Description

Absorbent article

The present invention relates to an absorbent article for use on a wearer's lower jaw. Specifically, the present invention relates to an absorbent article suitable for use in the lower jaw of a wearer who is placed in a lateral or semi-recumbent position.

Absorbent articles such as disposable diapers or overlapping inner surfaces such as underwear have been known for use in adults. Such absorbent articles are referred to as urination pads or absorbent pads. The urination pad is generally formed to have a front portion that covers the wearer's abdomen, that is, a front portion that covers the back of the wearer, that is, a rear portion that covers the wearer's back, and a lower jaw that abuts the wearer's lower jaw between the front and rear bodies (front and rear faces). Planar shape (Patent Document 1, etc.).

In addition, at the nursing site, when the caregiver puts the urination pad on the chin of the wearer (the care recipient), the urination pad is sometimes folded in the longitudinal direction, so that the cross section of the urination pad becomes W-shaped and then sandwiched. The squat of the wearer (see Figure 49). By folding into a W-shape, the convex portion at the center of W abuts on the sexual organs, so that it is easy to absorb urine. Further, when the wearer is a male, the urination pad is U-shaped, and the penis is placed in contact with the penis to be placed at the bottom of the U, and the urinary excretion direction is guided to design.

Also, among the wearers, there are symptoms such as paralysis or joint flexion, which cannot be lying face up, and only those in the lateral or semi-recumbent position can be taken. As shown in Fig. 50, in the state of lying only in the lateral or semi-recumbent position, since the two legs are often tightly closed, the urination pad needs to be sandwiched between the wearer's feet. However, if the urination pad is folded into a W shape or a U shape and is sandwiched in a state in which the thickness is formed, a gap is formed between the urination pad and the wearer's lower jaw, and it is easy to leak from the gap. Problems with urine (see Figure 49).

Further, as shown in Fig. 49, the general urination pad 300 has a structure in which the absorbent body 303 is interposed between the liquid permeable topsheet 301 and the liquid-impermeable back sheet 302. In this case, if the urination pad 300 is folded into a W shape, the liquid-impermeable back sheet 302 abuts against the inner thigh of both sides of the wearer. However, if the liquid-impermeable back sheet 302 abuts against the inner thigh, it is impossible to absorb urine flowing along the inner thigh with the urination pad, and there is a problem that urine easily leaks from between the back sheet 302 and the inner thigh. In addition, if the liquid-impermeable back sheet 302 continues to abut against the wearer's skin, it may become a cause of skin problems.

Accordingly, it is an object of the present invention to provide a body fluid which can be fitted without causing a gap in the lower jaw of a wearer who adopts a lateral or semi-recumbent posture, and can appropriately absorb body fluid flowing along the inner thigh to prevent leakage to the outside. Absorbent items.

[1. First Embodiment]

The first embodiment of the absorbent article 100 of the present invention will be described with reference to Figs. 1 to 5 . Fig. 1 is a perspective view showing an outline of an absorbent article 100 according to the present invention. As shown in Fig. 1, the absorbent article 100 according to the present invention is formed in a cylindrical three-dimensional shape having a space 4 therein. In the present embodiment, the back side of both ends of the planar rectangular outer absorbent body 10 is formed into a tubular shape having a space 4 extending in the depth direction (D). The absorptive body 10 forming a three-dimensional shape has a top surface portion 1 having a plane abutting against a lower jaw of the wearer, left and right side surface portions 2, 3 (left side surface portion 2 and right side surface portion 3), and the like from the top surface portion 1 The left and right sides extend toward the non-opposing side of the skin; and the space 4 is formed on the left and right side portions 2, 3 between. This space 4 penetrates from the end of the wearer's ventral side to the end of the back side, and penetrates in the depth direction (D). Further, a liquid-impermeable leakage preventing sheet 20 is attached to the lower end portion 5 of the left and right side surface portions 2, 3 of the absorbent body 10. The leakage preventing sheet 20 is joined to the left and right side surface portions 2 and 3, and also functions to connect the side surface portions 2 and 3. Further, a through hole 7 connected to the internal space 4 is formed on the top surface portion 1 of the absorbent body 10.

Next, each element constituting the absorbent article 100 will be specifically described. Fig. 2 is an exploded perspective view showing the absorbent article 100, and Fig. 3 is a cross-sectional view showing the absorbent article. As shown in FIGS. 2 and 3, the absorbent article 100 includes an absorbent main body 10 and a leakage preventing sheet 20 attached to the lower portion thereof.

The absorbent body 10 is an element for absorbing body fluids that are retained from the wearer's lower jaw. The absorbent body 10 has a configuration in which the absorbent body 13 is interposed between a plurality of sheet members. Specifically, the absorbent body 10 has an outer sheet 11 constituting the outer surface (the skin facing surface) of the absorbent article 100, an inner sheet 12 constituting the inner surface (the skin non-opposing surface) of the absorbent article 100, and The absorber 13 between the two sheets 11, 12. In the present embodiment, the outer sheet 11, the inner sheet 12, and the absorber 13 are formed in a rectangular shape. However, the shapes of the outer sheet 11, the inner sheet 12, and the absorber 13 are not limited to rectangular shapes, and may be circular, elliptical, or other polygonal shapes. Further, the outer sheet 11 and the inner sheet 12 have a length and a width which are larger than the absorbent body 13, and are joined by a well-known adhesive or heat fusion or ultrasonic welding to surround the periphery of the absorbent body 13. Therefore, the absorber 13 is in a state of being sealed to the inside of the outer sheet 11 and the inner sheet 12 to be joined around.

The outer sheet 11 is a sheet-like member for directly contacting the skin of the wearer and allowing body fluid such as urine to penetrate the absorbent body 13. Therefore, the outer sheet 11 is made of a highly liquid permeable material. Forming the outer sheet An example of the liquid permeable material of 11 is a woven fabric, a non-woven fabric or a porous film. Further, as the outer sheet 11, a fiber obtained by hydrophilizing a fiber such as polypropylene or a thermoplastic resin such as polyethylene, polyester or nylon may be used to form a nonwoven fabric. Examples of the non-woven fabric include a breathable nonwoven fabric, a point-bonded nonwoven fabric, a spunbonded nonwoven fabric, and a melt blown nonwoven fabric.

The inner sheet 12 does not directly contact the skin of the wearer, but is preferably formed of a material that allows the body fluid introduced into the space 4 through the through hole 7 of the top surface 1 to penetrate the material of the absorber 13. form. Therefore, the inner sheet 12 and the outer sheet 11 are preferably made of a highly liquid permeable material. Examples of liquid permeable materials are as described above. However, the inner sheet 12 does not necessarily need to be formed of a liquid permeable material, and may be formed of a liquid impermeable material. An example of a liquid-impermeable material is a plastic film composed of a polyethylene resin. In particular, in the case where the inner sheet 12 is formed of a liquid-impermeable sheet member, in order to ensure air permeability, it is preferable to use a microporous polyethylene film in which a plurality of fine pores of 0.1 to 4 μm are formed.

The absorber 13 is a member for absorbing body fluid such as urine and holding the absorbed body fluid. The absorber 13 is disposed between the outer sheet 11 and the inner sheet 12. Further, as will be described later, the absorber 13 disposed on the outer sheet 11 and the inner sheet 12 is not limited to one layer, and may be two or more layers. Further, the absorber 13 may be joined to the outer sheet 11 and the inner sheet 12 by a hot-melt adhesive or the like so as not to be displaced between the outer sheet 11 and the inner sheet 12. The absorbent body 13 is basically composed of an absorbent material 13a and a core coated sheet 13b covering the absorbent material 13a. As the absorbent material 13a, a fluff pulp obtained by crushing a fibrous material such as conifer or hardwood, or a superabsorbent polymer (SAP) or a hydrophilic sheet can be used. In addition, as for the absorbent material 13a, one of a fluff pulp, a superabsorbent polymer, and a hydrophilic sheet may be used alone, or two or more types may be used in combination. general In other words, the absorbent material 13a is composed of a superabsorbent polymer dispersed in the fluff pulp. The core covering sheet 13b is a sheet member for covering the absorbent material 13a to maintain its shape. As the core-coated sheet 13b, a liquid-permeable sheet member is used. As an example of the core-coated sheet 13b, a tissue such as toilet paper or a well-known non-woven fabric can be used.

The leakage preventing sheet 20 is a sheet-like member for preventing body fluid absorbed by the absorbent body 10 from leaking to the outside. The leakage preventing sheet 20 can also be used as a handle when the absorbent article 100 absorbing the body fluid is taken out from the lower jaw of the wearer. Therefore, the leakage preventing sheet 20 is attached to at least a part of the outer surfaces of the left and right side surface portions 2, 3 of the absorbent body 10. Specifically, the leakage preventing sheet 20 is preferably attached to the outside of the lower end portion 5 of the left and right side portions 2, 3 of the absorbent body 10. In order to prevent leakage of body fluid, the leakage preventing sheet 20 is made of a liquid-impermeable material. As described above, an example of the liquid-impermeable material is a plastic film composed of a polyethylene resin. In particular, in order to maintain liquid permeability while ensuring air permeability, it is preferable to use a microporous polyethylene film in which a plurality of fine pores of 0.1 to 4 μm are formed.

The outer sheet 11, the inner sheet 12, and the absorber 13 are bonded together in an unfolded state as shown in Fig. 2 to form the absorbent body 10, and the left and right ends of the absorbent body 10 in the width direction (W) are inward. The face sheet 12 is bent sideways, and its lower end portion is fitted with the leakage preventing sheet 20. Thereby, the absorbent article 100 including the absorbent main body 10 and the leakage preventing sheet 20 has a cylindrical three-dimensional shape as shown in FIG. Further, as shown in FIG. 3, a leakage preventing sheet 20 is attached to the lower end portion 5 of the absorbent body 10 across the left side surface portion 2 and the right side surface portion 3. Therefore, the leakage preventing sheet 20 can be said to be responsible for the function of joining the left side surface portion 2 and the right side surface portion 3 of the absorbent body 10.

In the example shown in Fig. 3, the absorbent body 10 has a top surface portion 1 that abuts against a plane of the wearer's lower jaw, and left and right sides extending from the left and right sides of the top surface portion 1 toward the skin non-opposing surface side. Side part 2, 3 are connected integrally. Further, a mountain-shaped fold 8 is formed on the boundary line between the top surface portion 1 and the left and right side surface portions 2, 3. Thereby, the cross section of the absorbent body 10 becomes approximately an inverted triangle. Further, although the top surface portion 1 is located between the left and right mountain-shaped folds 8, the top surface portion 1 has a slightly flat plane. As described above, the top surface portion 1 is easily formed in close contact with the lower jaw of the wearer by forming a flat surface without being bent on the top surface portion 1. Further, as shown in Fig. 3, the length B of the width direction (W) of the top surface portion 1 is preferably, for example, 20 mm to 150 mm, and particularly preferably 30 mm to 100 mm.

Further, as shown in Fig. 3, the left and right side surface portions 2, 3 are respectively divided into a lower end portion 5 which is a region where the leakage preventing sheet 20 is joined, and a liquid absorbing portion which is a region from the lower end portion 5 to the top surface portion 1 (the mountain-shaped fold 8). 6. The leakage preventing sheet 20 is not joined to the liquid suction portion 6. Therefore, the left and right side surface portions 2, 3 can absorb the body fluid from the outer side in the liquid-absorbent portion 6. When the absorbent article 100 is sandwiched between the lower jaw of the wearer in a side lying position or a semi-recumbent posture, and the top surface portion 1 is brought into contact with the lower jaw of the wearer, the left and right side portions 2, 3 abut against wearing. The inner thigh of both feet. Therefore, by forming the liquid absorbing portion 6 capable of absorbing the body fluid from the outer surface side on the left and right side surface portions 2, 3, the body fluid flowing along the inner thigh of the wearer can be effectively absorbed. Further, the length T of the liquid-absorbent portion 6 in the height direction (H) is preferably, for example, 20 mm to 200 mm, more preferably 50 mm to 150 mm. Further, the left and right side surface portions 2, 3 may be mutually adhered by a hot melt adhesive or the like at the lower end portion (the end portion on the side of the leakage preventing sheet 20).

As shown in FIGS. 1 to 3, a through hole 7 is formed in the top surface portion 1 of the absorbent body 10, and body fluid can be introduced into the space 4 through the through hole 7. Therefore, as shown in Fig. 2, the through hole 7 is formed on all of the outer sheet 11, the inner sheet 12, and the absorber 13 which constitute the top surface portion 1. The through hole 7 is preferably formed in an elongated shape extending along the depth direction (D) of the absorbent body 10. The shape of the through hole 7 is not particularly limited, and may be formed as a slightly hexagon as shown in FIG. 2 and the like. Shape, or square shape, elliptical shape. Further, the through hole 7 may be a simple slit. Further, the through hole 7 may be a slit having one end reaching the front end or the rear end of the absorbent body 10, or may be a crack having both ends reaching the front end and the rear end of the absorbent body 10. As described above, by forming the through hole 7, the discharged body fluid can be penetrated not only from the outer sheet 11 side but also from the inner sheet 12 side to the absorber 13. Therefore, even if a large amount of body fluid is excreted at once, it is possible to effectively prevent leakage of urine. Further, when the wearer is a male, the direction of excretion of urine can be guided or fixed by inserting the penis into the through hole 7.

Fig. 4 is a view showing an example of a state in which the absorbent article 100 is sandwiched between the wearer's lower jaw. As shown in Fig. 4, the top surface portion 1 of the absorbent body 10 which forms a flat surface is in close contact with the lower jaw of the wearer, and the side surface portions 2, 3 on the left and right sides thereof are in close contact with the inner thigh of the wearer. Further, since the space 4 is held between the left and right side surface portions 2, 3, the absorbent body 10 as a whole has a high cushioning property, and the adhesion state to the lower jaw and the inner thigh can be maintained. Thereby, a gap is not generated between the absorbent body 10 and the wearer's skin, even in the case of wearing the wearer in the lateral or semi-recumbent posture, it is possible to effectively prevent the side from the top face 1 or Leakage of urine on the side portions 2, 3 side. Further, since the leakage preventing sheet 20 is added to the lower end portion 5 of the absorbent body 10, it is possible to avoid the soiling of the underwear, the sheets, or the disposable diaper which is used after being worn. Further, when the absorbent article 100 is exchanged, the leakage preventing sheet 20 is taken out as a handle, and the exchange work can be easily performed without soiling the hand.

As described above, since the absorbent article 100 of the present invention is intended to be sandwiched between the wearer's lower jaw and the user, it is not necessary to cover the front body of the wearer's abdomen or the back body covering the back of the wearer as in the conventional urination pad. Therefore, as shown in Fig. 1, it is sufficient that the length L of the entire depth direction (D) of the absorbent article 100 of the present invention is 80 mm to 250 mm or 100 mm to 200 mm. With the present invention, such small absorption can be achieved Sexual items.

Figs. 5(a) to 5(e) are diagrams showing an example of a manufacturing procedure of the absorbent article 100 according to the first embodiment. In Fig. 5, a cross-sectional view of each V-V line is shown. The absorbent article 100 can be manufactured in accordance with the steps shown in Figs. 5(a) to 5(e). That is, first, a rectangular outer sheet 11 is prepared (Fig. 5(a)). Further, at this time, the through hole 7 is not formed on the outer sheet 11. Next, the rectangular absorber 13 in which the through hole 7 is formed is placed on the skin non-opposing surface side of the outer sheet 11, and the inner sheet 12 is further placed on the skin non-opposing surface side of the absorber 13 (Fig. 5) (b)). At this time, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. Further, the absorber 13 may be joined to either or both of the outer sheet 11 and the inner sheet 12. Thereby, the absorbent body 10 can be obtained. Further, at this stage, the through hole 7 is not formed on the outer sheet 11. Next, the absorbent body 10 is folded in half toward the inner sheet 12 along the through hole 7 formed in the absorber 13 (Fig. 5(c)). In other words, the outer sheet 11 is folded outward and the inner sheet 12 is inside. At this time, the through hole 7 of the absorber 13 is located at the apex of the fold. Thereafter, the through hole 7 of the absorber 13 positioned at the apex portion is cut away, and the through hole 7 having substantially the same shape as the absorber 13 is formed on both the outer sheet 11 and the inner sheet 12 (Fig. 5(d)) . At this time, since the outer sheet 11 and the inner sheet 12 are overlapped with the through hole 7 of the absorber 13, the outer sheet 11 and the inner sheet 12 are cut away from the same position as the through hole 7 of the absorber 13. Then, the through hole 7 can be formed substantially simultaneously on both the outer sheet 11 and the inner sheet 12. Thereafter, the leakage preventing sheet 20 is joined at a position corresponding to the lower end portion of the absorbent body 10 (Fig. 5(e)). Further, a step of forming a mountain-shaped fold 8 (or a valley-shaped fold 9 to be described later) at an appropriate position of the absorbent body 10 constituting the absorbent article 100 may be added. Further, it is also possible to increase the end portion on the side opposite to the apex of the folded edge by the hot melt adhesive or the like (that is, the side of the leakage preventing sheet 20 is disposed. End) steps.

According to the above manufacturing steps, the absorbent article 100 in which the through holes 7 are formed can be efficiently manufactured. Further, as shown in FIG. 5(c), after the through hole 7 is formed in the absorber 13, the entire absorbent body 10 is folded in half along the through hole 7, and the top surface attached to the absorbent body 10 can be attached. The fold on 1 is limited to a minimum. That is, as described above, the top surface portion 1 preferably has a flat surface and does not have any wrinkles. However, since the fold is formed along the through hole 7 at the time of manufacture, the wrinkle attached to the top surface portion 1 can be minimized. Thereby, a state in which the fold does not remain can be formed on the top surface portion 1 when it is worn.

In the present embodiment, the absorption body 13 and the sub-absorbent body 14 are superposed on the left and right side surface portions 2, 3, and the amount of absorption of the body fluid in the side surface portions 2, 3 is increased. In particular, the body fluid introduced into the space 4 through the through hole 7 of the top surface portion 1 can be absorbed in a large amount by the sub-absorber 14 disposed on each of the side surface portions 2 and 3. Therefore, this embodiment can be said to be a form suitable for a male who uses a penis inserted into the through hole 7 of the top surface portion 1. Further, as shown in Fig. 10, it is preferable that the sub-absorbent body 14 is disposed so as to overlap the absorber 13 at least on the lower end portion 5 side of the left and right side surface portions 2, 3. However, the sub-absorbent body 14 may be disposed to overlap the absorber body 13 over the entire left and right side surface portions 2 and 3. Further, although not shown in the drawings, the sub-absorbent body 14 may be disposed on the skin facing surface side of the absorber 13 (main absorber), that is, between the absorber 13 and the outer sheet 11.

11(a) to 11(e) are diagrams showing an example of a manufacturing procedure of the absorbent article 100 according to the third embodiment. In Fig. 11, a cross-sectional view of each XI-XI line is shown. First, a rectangular outer sheet 11 is prepared, and an absorber 13 (main absorber) in which the through holes 7 are formed is placed on the skin non-opposing surface side (Fig. 11(a)). Second, in the equivalent of the absorber Further, one sub-absorbent body 14 is overlapped at the position of the side surface portions 2 and 3 on the non-opposing surface side of the skin 13 (Fig. 11(b)). Further, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13 and the sub-absorber 14. Thereby, the absorbent body 10 can be obtained. Next, the absorbent body 10 is folded in half toward the inner sheet 12 along the through hole 7 formed in the absorber 13 (Fig. 11(c)). In other words, the outer sheet 11 is folded outward and the inner sheet 12 is inside. At this time, the through hole 7 of the absorber 13 is located at the apex of the fold. Thereafter, the through hole 7 of the absorber 13 positioned at the apex portion is cut away, and the through hole 7 having substantially the same shape as the absorber 13 is formed on both the outer sheet 11 and the inner sheet 12 (Fig. 11(d)) . Thereafter, the leakage preventing sheet 20 is joined at a position corresponding to the lower end portion of the absorbent body 10 (Fig. 11(e)). Further, a step of forming a mountain-shaped fold 8 (or a valley-shaped fold 9 to be described later) at an appropriate position of the absorbent body 10 constituting the absorbent article 100 may be added.

[4. Examples of changes in absorbent articles]

Next, a modification of the absorbent article will be described with reference to Figs. 12 to 14 . The variation described here can also be applied to any of the above embodiments. Further, in the drawings of Fig. 12 and subsequent figures, the cross-sectional shape of the absorbent body 10 is simplified.

Fig. 12(a) shows an example in which the cross-sectional shape of the absorbent body 10 is an inverted triangle as in the above-described embodiment. In the case of this example, a mountain-shaped fold 8 is formed on the boundary line between the top surface portion 1 and the left and right side surface portions 2, 3. Therefore, the top surface portion 1 forms a flat surface. The leakage preventing sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2, 3, and is provided across the side surface portions 2, 3.

Fig. 12(b) shows an example in which the cross-sectional shape of the absorbent body 10 is slightly T-shaped. In this case, a mountain-shaped fold 8 is formed on the boundary line between the top surface portion 1 and the left and right side surface portions 2, 3, and a valley shape is formed at a position corresponding to the liquid-absorbent portion 6 of the left and right side surface portions 2, 3. Fold 9. In the region below the valley fold 9, the left and right side portions 2, 3 abut against each other and extend straight. Further, in the region where the left and right side surface portions 2, 3 abut, it is preferable not to join the two in order to widen the space 4 between the left and right side surface portions 2, 3. However, a portion where the left and right side surface portions 2, 3 are in contact with each other may be joined by a hot melt adhesive or the like. The leakage preventing sheet 20 is added to the lower end portions 5 of the left and right side portions 2, 3. The slightly T-shaped absorbent body 10 is folded along the mountain-shaped folds 8 and the valley-shaped folds 9, so that the flat top surface portion 1 is not provided with a fold and is densely accommodated.

Fig. 12(c) shows an example in which the cross-sectional shape of the absorbent body 10 is slightly tapered. In the case of this example, the absorbent body 10 is not formed with buckling (mountain-shaped folds and valley-shaped folds), and the left and right ends are bound by the leakage preventing sheet 20 by the flexible bending of the absorbent body 10. Therefore, among the absorbent body 10, the top surface portion 1 having a flat surface that contacts the lower jaw of the wearer protrudes toward the skin side of the wearer, unlike the one shown in Fig. 12 (a) or Fig. 12 (b). As in the example, it has a flat plane. Further, in the example shown in FIG. 12(c), when the boundary between the top surface portion 1 and the left and right side surface portions 2, 3 is not formed, the absorbent body is applied in the width direction in the natural state. The portion to be divided is the top surface portion 1, and the division of the portion is such that the absorbent body 10 is divided into regions having the maximum width to be the top surface portion 1. The leakage preventing sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2, 3, and is provided across the side surface portions 2, 3. Since the teardrop-shaped absorbent body 10 has high cushioning properties and no unevenness, the skin feels good and does not give mechanical comfort to the wearer's skin.

Fig. 12 (d) shows an example in which the cross-sectional shape of the absorbent main body 10 is slightly rounded on the upper side and slightly rectangular on the lower side. In the case of this example, a valley-shaped fold 9 is formed in the liquid-absorbent portion 6 of the left and right side surface portions 2, 3 of the absorbent body 10. In the region above the valley fold 9, no buckling is formed, and the flexible body of the absorbent body 10 is bent to form a slight The profile is round. Therefore, the top surface portion 1 of the absorbent body 10 is entirely convex toward the skin side of the wearer, and there is no flat surface. On the other hand, in the region below the valley fold 9, the left and right side portions 2, 3 abut against each other and extend straight. The portions where the left and right side portions 2, 3 abut each other may be joined by a hot melt adhesive or the like. Further, the portion where the left and right side surface portions 2, 3 abut each other serves as a handle function when the absorbent article 100 is taken out and inserted into the lower jaw of the wearer. In the example shown in Fig. 12(d), for example, the leakage preventing sheet 20 extends longer upwards and is easier to grasp. In the example shown in Fig. 12(d), when the absorbent article 100 is required to partially contact the narrow portion of the wearer's lower jaw, it can be said that it is an easy-to-use article.

Fig. 13(a) shows an example in which the cross-sectional shape of the absorbent body 10 is slightly rounded. In this case, the absorbent body 10 is completely cylindrical. Further, a leakage preventing sheet 20 is added to a portion of the outer surface of the absorbent body 10. Further, the portion where the leakage preventing sheet 20 is added is referred to as the lower end portion 5 of the left and right side surface portions 2, 3, and the portion opposite to the lower end portion 5 is referred to as the top surface portion 1, and the lower end portion 5 and the top surface portion 1 are provided. The area between them serves as the liquid absorbing portion 6.

Fig. 13(b) shows an example in which the cross-sectional shape of the absorbent body 10 is slightly inverted. In this case, the absorbent body 10 has a top surface portion 1 having a plane abutting against the wearer's lower jaw, and is divided into left and right at the crack 7'. The left and right side surface portions 2, 3 extend toward the skin non-opposing surface side of the top surface portion 1 at a position corresponding to the crack 7' at the center in the width direction of the top surface portion 1. Further, a space 4 is formed between the left and right side surface portions 2, 3. The crack 7' of the top surface portion 1 opens into the space 4 between the left and right side portions 2, 3. Therefore, this crack 7' can be said to have the same function as the aforementioned through hole 7. Further, a valley-shaped fold 9 is formed on the boundary line between the top surface portion 1 and the left and right side surface portions 2, 3. Furthermore, the left and right side portions 2, 3 are integrally connected at the lower ends of the side portions, on the left and right sides. A mountain-shaped fold 8 (folding line) is formed on the boundary line of the portions 2 and 3. Therefore, the absorbent body 10 is in a state in which the lowermost end portion is closed. In other words, the absorbent body 10 has a shape in which it is folded at the center in the width direction to form a mountain-shaped fold 8 (folding line), and is bent in the opposite direction on the left and right sides in the width direction to form a valley-shaped fold 9. In the example shown in Fig. 13(b), the mutually opposing planes of the left and right side portions 2, 3 may be partially or entirely joined by a hot melt adhesive or the like, or may not be joined at all. In particular, the body fluid is introduced into the space 4 through the crack 7' of the top surface portion 1, or the penis is inserted into the space 4, and the opposing planes of the left and right side portions 2, 3 are preferably not joined, or only partially joined. . The leakage preventing sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2, 3, and is provided across the side surface portions 2, 3. At this time, the folds corresponding to the mountain-shaped folds 8 (folding lines) on the boundary line between the left and right side surface portions 2, 3 may be formed on the leakage preventing sheet 20. In the example shown in Fig. 13(b), even a solid object can be accommodated in the space 4 between the left and right side surface portions 2, 3. Therefore, it can be suitably used as a gasket for storing a soft stool or the like.

Fig. 13(c) is a further variation of the example shown in Fig. 13(b). In the example shown in Fig. 13(c), the left side face 2 and the right side face 3 are separated at the lower end. That is, in this example, the left absorbent top surface 1 and the left side surface 2 are formed by the first absorbent body 10, and the right top surface 1 and the right side surface 3 are formed by the second absorbent body 10 by the two absorbent bodies 10. . The left side surface portion 2 of the first absorbent body 10 and the right side surface portion 3 of the second absorbent body 10 are connected to the leakage preventing sheet 20 at the lower end portion 5, and the two absorbent bodies 10 are joined. The example shown in Fig. 13(c) is basically the same as the example shown in Fig. 13(b) except that the absorptive body 10 is divided into two on the right and left sides.

Fig. 14(a) shows an example in which one absorbent body 10 is bent so that the absorbent body 10 is superposed on the top surface portion 1 into two layers. That is, in this example, the absorbent body 10 is overlapped on the top surface portion 1 into two The layer, the upper layer portion and the left side surface portion 2 are integrally connected, and the lower layer portion and the right side surface portion 3 are integrally connected. A mountain-shaped fold 8 is formed on the boundary line between the top surface portion 1 and the left and right side surface portions 2, 3, and the top surface portion 1 has a slightly flat surface. Further, the left and right side surface portions 2, 3 are integrally connected at the lower end, and a mountain-shaped fold 8 is formed on the boundary line between the two. Therefore, the cross-sectional shape of the absorbent body 10 becomes a slightly inverted triangle. The leakage preventing sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2, 3, and is provided across the side surface portions 2, 3. In the example shown in Fig. 14(a), since the absorbent body 10 is superposed on the top surface portion 1 in two layers, the amount of absorption of the body fluid on the top surface portion 1 can be increased.

Fig. 14(b) shows an example in which the absorbent main body 10 constituting the top surface portion 1 and the absorbent main body 10 constituting the left and right side surface portions 2, 3 are separately provided. In this case, the left and right side surface portions 2, 3 are formed by one absorbent body 10, and the absorbent body 10 is bent at the lower end of the mountain-shaped fold 8 to have a substantially V shape. The other side is bent toward the left and right sides and the inner side in the width direction of the absorbent body 10 constituting the top surface portion 1, and overlaps the outer surface sides of the upper end portions of the left and right side surface portions 2, 3, and the overlapping is performed by an adhesive or the like. section. The top surface portion 1 can be made flat without folds. In this manner, the top surface portion 1 and the left and right side portions 2, 3 may be formed by the respective absorbent bodies 10. Further, the leakage preventing sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2, 3, and is provided across the side surface portions 2, 3.

Fig. 14(c) is a view showing an example in which one absorbent body 10 is bent into two layers in which the absorbent body 10 is overlapped at the lower end portion 5. That is, in this example, the top surface portion 1 and the left and right side surface portions 2, 3 are integrally connected via the mountain-shaped folds 8. On the other hand, the portion where the left side surface portion 2 is formed is folded inward at the lower end, and the portion where the right side surface portion 3 is formed is folded inward at the lower end, and a portion overlaps the outer surface of the left side surface portion 2. In this way, the lower end sides of the left and right side portions 2, 3 may be folded and overlapped into two Floor. In this case, the amount of absorption of the body fluid at the lower end portion 5 of the absorbent body 10 can be increased. Further, the leakage preventing sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2, 3, and is provided across the side surface portions 2, 3.

Fig. 14(d) shows an example in which one absorbent body 10 is bent and the cross-sectional shape is a slightly inverted triangular shape, and the joint of the end portion of the absorbent body 10 is positioned on the right side surface portion 3 (or the left side surface portion 2). That is, in this example, the top surface portion 1 and the left and right side surface portions 2, 3 are integrally connected via the mountain-shaped folds 8. Further, the left and right side surface portions 2, 3 are integrally connected at the lower end, and a mountain-shaped fold 8 is formed on the boundary line. However, in this case, the joint at the end of the absorbent body 10 is located on the right side face 3. Thus, the leakage preventing sheet 20 is added so as to cover the joint. Therefore, in this example, the leakage preventing sheet 20 is attached only to the portion corresponding to the right side surface portion 3 of the absorbent body 10. In this manner, the leakage preventing sheet 20 is not limited to the lower end portion of the absorbent body 10, and may be attached to at least a portion of the outer surface of the absorbent body 10.

Further, in the examples shown in Figs. 12 to 14, the illustration of the through hole 7 of the top surface portion 1 is omitted. In the example shown in Figs. 12 to 14, the through hole 7 connected to the inner space 4 can be formed in the top surface portion 1 of the absorbent body 10 as in the first to third embodiments described above.

[5. Products containing absorbent articles]

Fig. 15 is a view schematically showing an example of a product in which a plurality of absorbent articles 100 are housed inside the package 200. In Fig. 15, the package 200 is depicted as a person having a rectangular parallelepiped or cubic internal space. As the package 200, a well-known person such as a bag shape or a box shape can be suitably used. Further, as the package 200, a well-known person such as paper, cloth, vinyl, or plastic can be used. The package 200 is not particularly limited as long as it has an internal space in which at least two or more absorbent articles 100 can be accommodated, and a well-known person can be suitably employed.

(a) of FIG. 15 is an example of a product in which the absorbent article 100 (see FIG. 12(b)) having a cross-sectional shape of the absorbent body 10 is housed in the package 200. As shown in Fig. 15 (a), each of the absorbent articles 100 is folded in the left and right mountain-shaped folds 8 provided between the top surface portion 1 and the left and right side surface portions 2, 3, and is formed in the valley fold provided on the left side surface portion 2. The folded state is arranged in the package 200. In this manner, the top surface portions 1 of the respective absorbent articles 100 are arranged in a state of being horizontally tilted, and it is not necessary to form a fold on each of the top surface portions 1 during storage in the package 200. Thereby, the flat state of the top surface portion 1 can be maintained, so that the top surface portion 1 can be easily brought into contact with the lower jaw of the wearer. Further, by folding the absorbent article 100 as shown in Fig. 15 (a), the plurality of absorbent articles 100 can be densely stored in the package 200.

(b) of FIG. 15 is an example of a product in which the cross-sectional shape of the absorbent body 10 is a slightly inverted triangular shape of the absorbent article 100 (see FIG. 12( a ) and the like). As shown in Fig. 15 (b), each of the absorbent articles 100 is folded in the left and right mountain-shaped folds 8 provided between the top surface portion 1 and the left and right side surface portions 2, 3. Further, each of the absorbent articles 100 forms a valley-shaped fold 9 only on the left side surface portion 2 (or the right side surface portion 3) among the left and right side surface portions 2, 3, and the valley-shaped folds 9 are also folded. As described above, in the example shown in FIG. 15(b), the top surface portions 1 of the respective absorbent articles 100 are arranged in a state of being horizontally tilted, and in the case of housing in the package 200, the top surface portions 1 are not required. The fold is formed on it.

Fig. 16 is a view showing a modification of the case where the absorbent article 100 is housed in the package 200. In the example shown in Fig. 16, the leakage preventing sheet 20 has a fixing portion 21 which is inseparably joined to the lower end portion 5 of the absorbent body 10, and an extending portion 22 which extends from either the left and right ends of the fixing portion 21 . In a state in which the absorbent body 10 is folded so that the top surface portion 1 is laterally tilted, the extending portion 22 of the leakage preventing sheet 20 has an extended length which can cover the top surface portion 1 of the absorbent body 10. Delay The stretched portion 22 may be temporarily covered in a state in which the top surface portion 1 or the side surface portions 2, 3 are partially peeled off. As described above, in a state of being housed in the package 200, a part (extension portion 22) of the leakage preventing sheet 20 covers the top surface portion 1 of the absorbent body 10, so that the sanitary state of the top surface portion 1 can be maintained. Further, as shown in Fig. 16, the leakage preventing sheet 20 may have an eyelet 23 formed between the fixing portion 21 and the extending portion 22, and the fixing portion 21 and the extending portion 22 may be separated along the eyelet 23. At the time of use, the extending portion 22 is separated from the fixing portion 21 and discarded, and the extending portion 22 does not become an obstacle.

[6. Further changes of absorbent articles]

Fig. 17 is a plan view showing a further variation of the absorbent article. In addition, Fig. 18 is a cross-sectional view schematically showing a cross-sectional shape of XVIII-XVIII shown in Fig. 17.

Fig. 17 is a view showing a state in which the absorbent body 10 is folded in the order of (a), (b), and (c), and finally the state shown in (c) is obtained. In the unfolded state shown in Fig. 17 (a), the absorptive body 10 is divided into a front side portion 10a located on the front side (the ventral side of the wearer) in the depth direction (D) and a rear side portion (D) in the depth direction (D). The rear side portion 10b of the back side of the person and the central portion 10c between the front and rear side portions. In the example shown in Fig. 17, when the entire length of the depth direction (D) of the absorbent main body 10 is 100%, the length of the central portion 10c is set to be about 10% to 50%, and the front side portion 10a and the rear side are provided. The portion 10b bisects the remaining length portion. Further, the front side portion 10a and the rear side portion 10b of the absorbent body 10 have a longer length in the width direction (W) than the center portion 10c. In other words, the absorbent body 10 has left and right flap portions 10L and 10R extending outward in the width direction (W) from the center portion 10c in both the front side portion 10a and the rear side portion 10b. Therefore, the absorbent body 10 has a shape such as a slightly hourglass type in plan view. Further, in the example shown in Fig. 17, the right lobe R extending from the central portion 10c to the outer side in the width direction (W) is longer than the left lobe L.

Further, as shown in Fig. 17 (a), the extrusion line 13c may be formed in a rectangular grid pattern on the absorber 13 of the absorbent body 10. The extrusion line 13c is formed by pressing the absorber 13 from either the skin facing side and the skin non-opposite side, and is formed on the absorber 13 along the pressing line 13c. Concave. In addition, the hatched grid pattern refers to a plurality of extrusion lines 13c extending in a direction (oblique direction) inclined in the depth direction (D) and the width direction (W) in a plan view, and is divided into oblique lines. A pattern of square (diamond) non-extrusion areas. As described above, by forming a plurality of extrusion lines 13c on the absorber 13, the diffusibility of the body fluid contacting the surface of the absorber 13 can be improved, and the strength or shape retention of the entire absorbent body 10 can be improved. Further, although not shown in the drawings, the extrusion line 13c may be formed in a square lattice pattern on the absorber 13. The square lattice-like pattern referred to herein means a plurality of extruded lines 13c extending in parallel with the depth direction and intersecting a plurality of extruded lines 13c extending in parallel with the width direction to divide a square (tetragonal) non-extrusion region. picture of.

Then, as shown in Fig. 17(b), the portion of the absorbent body 10 including the left side portion 10a of the front side portion 10a and the rear side portion 10b is folded toward the inner side in the width direction (W) to the skin facing side. . Thereafter, as shown in Fig. 17 (c), the portion of the absorbent body 10 including the right side portion 10a of the front side portion 10a and the rear side portion 10b is folded inward in the width direction (W) to the skin facing surface. side. At this time, the left lobe portion 10L and the right lobe portion 10R are vertically overlapped, and the portions overlapping each other are joined by a hot-melt adhesive or the like. As a result, as shown in Fig. 17(c), the central portion 10c of the absorbent body 10 is formed to penetrate between the petals 10L and 10R of the front side portion 10a and the petals 10L and 10R of the rear side portion 10b. Hole 7. This through hole 7 has a function corresponding to the through hole 7 of each of the above embodiments.

Fig. 18 is a cross-sectional view showing a state shown in Fig. 17(c). As shown in Figure 18, follow the steps shown in Figure 17 (a) ~ (c) When the absorbent body 10 is bent, a tubular three-dimensional absorbent article 100 having a space inside can be obtained. As shown in Fig. 18, the front side portion 10a and the left and right flap portions 10L, 10R of the rear side portion 10b form the top surface portion 1 of the absorbent body 10. Further, a through hole 7 that opens into the internal space is formed on the top surface portion 1. Further, the left and right side surface portions 2, 3 of the absorbent body 10 are formed on the inner side in the width direction of the left and right flap portions 10L, 10R. Further, in the central portion in the width direction of the absorbent body 10, a mountain-shaped fold 8 is formed along the depth direction thereof. Further, at the lower end portion 5 of the side surface portions 2, 3 of the absorbent body 10, a leakage preventing sheet 20 is added across the left and right side surface portions 2, 3. As described above, the three-dimensional absorbent article 100 having the through hole 7 in the top surface portion 1 can also be obtained by the method shown in FIG.

[7. Fourth Embodiment]

Next, a fourth embodiment of the absorbent article 100 of the present invention will be described with reference to Figs. 19 to 24 . The fourth embodiment is the same as the above-described embodiment, and the description thereof is omitted, and the structure different from the above-described embodiment will be mainly described.

Fig. 19 is a perspective view showing an outline of an absorbent article 100 according to a fourth embodiment of the present invention. As shown in Fig. 19, the absorbent article 100 according to the present invention is formed into a cylindrical three-dimensional shape having a space 4 therein. In the present embodiment, the back sides of the both ends of the flat rectangular absorbent body 10 are joined together to form a cylindrical shape having a space 4 extending in the depth direction (D). The absorptive body 10 forming a three-dimensional shape has a top surface portion 1 having a plane abutting against a lower jaw of the wearer, left and right side surface portions 2, 3 (left side surface portion 2 and right side surface portion 3), and the like from the top surface portion 1 The left and right sides extend toward the skin non-opposing surface side; and the space 4 is formed between the left and right side portions 2, 3. This space 4 penetrates from the end of the wearer's ventral side to the end of the back side, and penetrates in the depth direction (D). Furthermore, on the left and right sides of the absorbent body 10 Liquid-impermeable leakage preventing sheets 20 are attached to the lower end portions 5 of the faces 2 and 3. The leakage preventing sheet 20 is joined to the left and right side surface portions 2 and 3, and also functions to connect the side surface portions 2 and 3. Further, a through hole 7 connected to the internal space 4 is formed on the top surface portion 1 of the absorbent body 10.

Fig. 20 is an exploded perspective view showing the absorbent article 100, and Fig. 21 is a cross-sectional view showing the absorbent article. As shown in Fig. 20 and Fig. 21, the absorbent article 100 is provided with an absorbent main body 10 and a leakage preventing sheet 20 attached to the lower portion thereof.

The outer sheet 11, the inner sheet 12, and the absorber 13 are bonded together in an unfolded state as shown in Fig. 20 to form the absorbent body 10, and the left and right ends of the width direction (W) of the absorbent body 10 are inward. The face sheet 12 is bent sideways, and its lower end portion is fitted with the leakage preventing sheet 20. Thereby, the absorbent article 100 including the absorbent main body 10 and the leakage preventing sheet 20 has a cylindrical three-dimensional shape as shown in FIGS. 19 and 21. Further, as shown in Fig. 21, the leakage preventing sheet 20 is attached to the lower end portion 5 of the absorbent main body 10 so as to extend across the left side surface portion 2 and the right side surface portion 3. Therefore, the leakage preventing sheet 20 can be said to be responsible for the function of joining the left side surface portion 2 and the right side surface portion 3 of the absorbent body 10.

Fig. 22 is a view showing an example of a state in which the absorbent article 100 is sandwiched between the wearer's lower jaw. As shown in Fig. 22, the top surface portion 1 of the absorbent body 10 which is formed into a flat surface is in close contact with the lower jaw of the wearer, and the side surface portions 2, 3 on the left and right sides thereof are in close contact with the inner thigh of the wearer. Further, since the space 4 is held between the left and right side surface portions 2, 3, the absorbent body 10 as a whole has high cushioning property, and the adhesion state to the lower jaw and the inner thigh can be maintained. Thereby, a gap is not generated between the absorbent body 10 and the wearer's skin, even in the case of wearing the wearer in the lateral or semi-recumbent posture, it is possible to effectively prevent the side from the top face 1 or Leakage of urine on the side portions 2, 3 side. Furthermore, since the leakage preventing sheet 20 is added to the lower end portion 5 of the absorbent body 10, Avoid underwear, bed sheets, or disposable diapers that are worn after being worn. Further, when the absorbent article 100 is exchanged, the leakage preventing sheet 20 is taken out as a handle, and the exchange work can be easily performed without soiling the hand.

As shown in Figs. 19 to 23, the absorbent article 100 of the present invention has a plurality of extrusion lines 31, 32, 33 formed on the absorbent body 13. Each of the extrusion lines is formed by partially recessing the absorber 13 in the thickness direction. In particular, each of the extruded lines can be formed by partially compressing and compressing the absorbent body 13 from both sides or either side of the skin facing side and the skin non-opposing side. Therefore, the density of the absorbent material 13a constituting the absorber 13 is increased at the portion where the extrusion line is formed. Thus, by forming the pressing line on the absorber 13, the absorber 13 is easily bent along the extrusion line. Further, since the density of the absorbent material 13a is increased at the portion where the extrusion line is formed, the absorber 13 can increase the stress applied to the external force in the direction parallel to the direction in which the extrusion line extends. Further, since the absorber 13 is partially recessed at the portion where the extrusion line is formed, the body fluid flows along the extrusion line, and the body fluid easily spreads in the direction in which the extrusion line extends. Further, the extrusion line may be formed on the skin facing surface side of the absorbent body 13, and may be formed on the non-opposing surface side of the skin, or may be formed on both sides of the skin facing surface side and the skin non-opposing surface side. Hereinafter, the pattern of the extrusion line formed on the absorber 13 will be described in more detail.

Fig. 23 is a view for explaining the pattern of the extrusion line formed on the absorbent body 13, showing the expanded state of the absorbent body 13. As shown in Fig. 23, the absorber 13 is formed with a first extrusion line 31 extending in the width direction at a portion corresponding to the top surface portion 1 of the absorbent body 10. The first extrusion line 31 is formed with a plurality of strips at predetermined intervals in the depth direction, and each of the extrusion lines of the first extrusion line 31 has a linear shape parallel to the width direction. The interval between the plurality of first extrusion lines 31 is not particularly limited, but for example, the interval between the first extrusion lines 31 is preferably 3 mm to 30 mm or 5 mm to 20 mm. Basically, the first extrusion line 31 extends over the width of the top surface portion 1. Extending to the entire area. That is, the first pressing line 31 preferably reaches the boundary between the top surface portion 1 and the left side surface portion 2 and the boundary between the top surface portion 1 and the right side surface portion 3. Further, as described above, the through hole 7 is formed in the top surface portion 1. In this case, the first extrusion line 31 preferably reaches the periphery of the through hole 7.

As described above, by forming the plurality of first pressing lines 31 along the width direction on the top surface portion 1, the stress of the top surface portion 1 against the external force applied from the width direction can be increased. By increasing the stress of the top surface portion 1, the top surface portion 1 or the space 4 located below it does not cause collapse, so the absorbent body 10 is more easily concatenated with the wearer's lower jaw and the inner thigh, and the shape of the space 4 can also be maintain. Further, by forming the first pressing line 31 extending in the width direction on the top surface portion 1 of the absorber 13, the body fluid that touches the top surface portion 1 is easily diffused in the width direction. Thereby, the body fluid can be quickly absorbed from the top surface portion 1 over the wide range of the side surface portions 2, 3, so that the effect of preventing leakage of urine can be improved.

Further, as shown in Fig. 23, the absorber 13 is formed at a position corresponding to the boundary between the top surface portion 1 of the absorbent body 10 and the left and right side surface portions 2, 3 (i.e., the mountain-shaped fold 8) in the depth direction. Two extrusion lines 32. Therefore, the absorbent body 10 is bent along the second extrusion line 32 formed on the absorbent body 13. That is, the chevron 8 of the absorbent body 10 is formed in a shape corresponding to the second extrusion line 32 of the absorbent body 13. As shown in Fig. 23, the second extrusion line 32 extends over a substantially entire area in the depth direction of the absorber 13. For example, when the length of the absorber 13 in the depth direction is 100%, the second extrusion line 32 preferably extends over a length range of 80 to 100% or 90 to 100% in the depth direction.

Further, the pair of left and right second extrusion lines 32 are formed in an arc shape that protrudes outward in the width direction. That is, the distance between the pair of right and left second pressing lines 32 is the narrowest at the front end portion and the rear end portion in the depth direction, and the widest at the center portion in the depth direction. Thus, the second extrusion line is formed by arcuating the left and right second extrusion lines 32, respectively. The region between the 32, that is, the top surface portion 1 is formed in a slightly elliptical shape in plan view. Further, when the top surface portion 1 is defined by the arc-shaped second extrusion line 32, when the absorbent body 10 is bent along the second extrusion line 32, the top surface portion 1 is formed as shown in Fig. 19. The shape in which the front end portion and the rear end portion of the depth direction rise. In other words, as shown in Fig. 19, in a state in which the absorbent body 10 is formed into a cylindrical three-dimensional shape, the distal end portions of the top surface portion 1 in the depth direction are located above the center portion in the depth direction. By making the second pressing line 32 into an arc shape, the state of the top surface portion 1 can be naturally maintained. Since the front end portion of the top surface portion 1 in the depth direction is narrower than the central portion and raised upward, it is suitably adapted to the lower abdomen of the wearer. Further, since the rear end portion of the top surface portion 1 in the depth direction is also narrower than the central portion and raised upward, it is suitable for the wearer's buttocks as appropriate. Thereby, leakage of urine or stool can be prevented more effectively.

Further, as shown in Fig. 19 or Fig. 23, the first extrusion line 31 is formed from the second extrusion line 32 on the left side to the second extrusion line 32 on the right side, or from the central through hole 7 to the left and right. The second extrusion line 32. Thus, by forming the first pressing line 31 over a substantially entire area in the width direction of the top surface portion 1, the shape of the top surface portion 1 defined by the second pressing line 32 can be maintained. That is, since the density of the absorbent material becomes higher at the portion where the first extrusion line 31 is formed, the absorber 13 has a stronger stress against the external pressure in the width direction. Therefore, even if the top surface portion 1 defined by the second pressing line 32 is sandwiched between the two legs of the wearer, the first pressing line 31 does not cause collapse, and the state of the plane can be maintained. .

Further, as shown in Fig. 23, the absorber 13 is formed with a plurality of third extrusion lines 33 extending in the depth direction on the respective side surface portions of the left side surface portion 2 and the right side surface portion 3. The plurality of third pressing lines 33 include an arc-shaped pressing line 33a that protrudes in the same direction as the second pressing line 32 in the unfolded state, and a linear pressing line 33b that extends in parallel with the depth direction. The arc-shaped pressing line 33a is formed in a cylindrical shape in the absorbent body 10. The state of the three-dimensional shape (see Fig. 19) can be said to be an arc shape that protrudes downward. By forming the arc-shaped pressing line 33a on the left and right side surface portions 2, 3, the top surface portion 1 is bent in the opposite direction in the depth direction, and the deformation required for the three-dimensional portion of the side surface portions 2, 3 can be given, not in the top surface portion. 1 A gap is formed between the wearer's lower abdomen or buttocks to prevent leakage. Further, in the region between the arc-shaped pressing line 33a and the second pressing line 32, the left and right side surface portions 2, 3 are easily held outwardly, and as a result, the absorption can be largely ensured. The space 4 inside the body 10 can capture a large amount of urine or stool. Further, since the linear pressing lines 33b are formed on the left and right side surface portions 2, 3, the stress on the external pressure from the depth direction can be improved. Similarly, when the arc-shaped extrusion line 33a or the linear extrusion line 33b included in the third extrusion line 33 is the same as the second extrusion line 32, when the length of the absorber 13 in the depth direction is 100%, the most It is good to extend the length range of 80~100% or 90~100% in the depth direction.

Figs. 24(a) to 24(e) are diagrams showing an example of a manufacturing procedure of the absorbent article 100 according to the fourth embodiment. In Fig. 24, a cross-sectional view of each XXIV-XXIV line is shown. The absorbent article 100 can be manufactured in accordance with the steps shown in Figs. 24(a) to 24(e). That is, first, a rectangular outer sheet 11 is prepared (Fig. 24(a)). Further, at this time, the through hole 7 is not formed on the outer sheet 11. Next, the rectangular absorbent body 13 in which the through hole 7 is formed is placed on the skin non-opposing surface side of the outer sheet 11, and the inner surface sheet 12 is placed on the skin non-opposing surface side of the absorbent body 13 (Fig. 24 (Fig. 24) b)). At this stage, a plurality of extrusion lines 31, 32, 33 are formed on the absorber 13 in the aforementioned pattern. Further, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. Further, the absorber 13 may be joined to either or both of the outer sheet 11 and the inner sheet 12. Thereby, the absorbent body 10 can be obtained. Further, at this stage, the through hole 7 is not formed on the outer sheet 11. Second, the absorptive ontology 10 is folded in half toward the inner sheet 12 along the through hole 7 formed in the absorber 13 (Fig. 24(c)). In other words, the outer sheet 11 is folded outward and the inner sheet 12 is inside. At this time, the through hole 7 of the absorber 13 is located at the apex of the fold. Thereafter, the through hole 7 of the absorber 13 positioned at the apex portion is cut away, and the through hole 7 having substantially the same shape as the absorber 13 is formed on both the outer sheet 11 and the inner sheet 12 (Fig. 24(d)) . At this time, since the outer sheet 11 and the inner sheet 12 overlap with the through hole 7 of the absorber 13, the outer sheet 11 and the inner sheet 12 are cut by the same position as the through hole 7 of the absorber 13. Then, the through hole 7 can be formed substantially simultaneously on both the outer sheet 11 and the inner sheet 12. Thereafter, the leakage preventing sheet 20 is joined at a position corresponding to the lower end portion of the absorbent body 10 (Fig. 24(e)). Further, a step of forming a mountain-shaped fold 8 at a position where the arc-shaped second extrusion line 32 is formed on the absorber 13 may be added. Further, a step of the end portion on the side opposite to the apex of the folded edge (that is, the end portion on the side of the leakage preventing sheet 20) may be added with a hot-melt adhesive or the like.

According to the above manufacturing steps, the absorbent article 100 in which the through holes 7 are formed can be efficiently manufactured. Further, as shown in Fig. 24(c), after the through hole 7 is formed in the absorber 13, the entire absorbent body 10 is folded in half along the through hole 7, and the top surface attached to the absorbent body 10 can be attached. The fold on 1 is limited to a minimum. That is, as described above, the top surface portion 1 preferably has a flat surface and does not have any wrinkles, but forms a fold which must be generated at the time of manufacture along the through hole 7, and the wrinkle attached to the top surface portion 1 can be minimized. Thereby, it is also possible to form a state in which the fold hardly remains on the top surface portion 1 at the time of wearing.

[8. Fifth embodiment]

Next, a fifth embodiment of the absorbent article 100 of the present invention will be described with reference to Figs. 25 and 26. The fifth embodiment is the same as the above-described embodiment, and the description thereof is omitted. Description will be made focusing on a structure different from the above-described embodiment.

Fig. 25 is an exploded perspective view showing the absorbent article 100 according to the fifth embodiment, and Fig. 26 is a cross-sectional view showing the absorbent article 100 according to the fifth embodiment. As shown in Fig. 25 and Fig. 26, in the absorbent article 100 according to the fifth embodiment, the absorbent body 13 has a structure in which the main absorbent body 13 and the secondary absorbent body 14 are laminated.

As shown in Fig. 26, in the present embodiment, the main absorbent body 13 is located on the top surface portion 1 and the left and right side surface portions 2, 3 of the absorbent main body 10. In other words, the main absorber 13 of the fifth embodiment has a structure similar to that of the absorber 13 of the fourth embodiment described above. On the other hand, the sub-absorbent body 14 is disposed only on the top surface portion 1 of the absorbent body 10. In particular, the sub-absorbent body 14 is disposed on the skin non-opposing surface side of the main absorbent body 13, that is, between the main absorbent body 13 and the inner surface sheet 12. Further, the sub absorber 14 may be composed of an absorbent material and a core coated sheet in the same manner as the main absorber 13. In the present embodiment, the main absorbent body 13 and the sub-absorbent body 14 are superposed on the top surface portion 1, and the amount of absorption of the body fluid in the top surface portion 1 is increased. Therefore, this embodiment can be said to be a form suitable for a woman who has a large amount of body fluid directly contacting the top surface portion 1. Further, in the present embodiment, the through hole 7 is formed in both the main absorber 13 and the sub absorber 14, and the through holes 7 of both are connected to the space 4. Further, although not shown in the drawings, the sub-absorbent body 14 may be disposed on the skin facing surface side of the main absorbent body 13, that is, between the main absorbent body 13 and the outer sheet 11.

Further, as shown in Figs. 25 and 26, in the present embodiment, the first extrusion line 31 extending in the width direction is formed in the sub-absorbent body 14 located on the top surface portion 1. The first extrusion line 31 is formed with a plurality of strips at predetermined intervals in the depth direction, and each of the extrusion lines of the first extrusion line 31 has a linear shape parallel to the width direction. The function of the first pressing line 31 formed on the top surface portion 1 is as described above. That is, by forming a plurality of first extrusion lines 31 on the sub-absorbent body 14 located on the top surface portion 1, The stress increase for the external force from the width direction can be improved, and the body fluid can be widely and rapidly diffused by the first extrusion line 31.

Further, in the present embodiment, the main absorber 13 has a plurality of third extrusion lines 33 extending in the depth direction on the side surface portions of the left side surface portion 2 and the right side surface portion 3. The third extrusion line 33 formed on the main absorber 13 is formed in a linear shape extending in parallel with the depth direction. By forming the linear third extrusion line 33 on the left and right side portions 2, 3, the stress on the external pressure from the depth direction can be improved.

As described above, in the present embodiment, the first extruding body 14 is formed with the first extruding line 31 extending in the width direction, and the main absorbent body 13 is formed with the third extruding line 33 extending in the depth direction. However, it is also possible to form both the first extrusion line 31 extending in the width direction and the third extrusion line 33 extending in the depth direction, for example, on the main absorbent body 13.

[9. Sixth Embodiment]

Next, a sixth embodiment of the absorbent article 100 according to the present invention will be described with reference to Figs. 27 and 28. Fig. 27 is an exploded perspective view showing the absorbent article 100 according to the sixth embodiment, and Fig. 28 is a developed view and a side view showing the absorbent article 100 according to the sixth embodiment. The sixth embodiment corresponds to a modification of the fourth embodiment described above, and the basic constituent elements are the same. However, the sixth embodiment is different from the fourth embodiment in that the outer shape of the expanded state of the absorbent article 100 is circular.

As shown in Fig. 27, in the sixth embodiment, the outer sheet 11, the inner sheet 12, and the absorber 13 are formed into a circular shape (or an elliptical shape) in plan view. Therefore, as shown in the plan view of Fig. 28(a), the absorbent body 10 in which the absorber 13 is laminated between the outer sheet 11 and the inner sheet 12 is also in an unfolded state, and its outer shape is circular in plan view ( Or oval). Further, as shown in the side view of Fig. 28(b), on the left and right sides of the lower end portions 5 of the left and right side surface portions 2, 3 of the absorbent body 10 The leakage preventing sheets 20 are attached to the faces 2 and 3. Thus, by molding the absorbent body 10 into a circular shape, the angle below the front end portion in the depth direction and the lower portion of the rear end portion can be removed as compared with the case where the absorbent body 10 is formed into a rectangular shape. Therefore, by molding the absorbent body 10 into a circular shape, the size of the entire absorbent article 100 can be made small. Further, in the embodiment in which the absorbent body 10 is formed into a rectangular shape, the corners may remain below the front end portion in the depth direction and below the rear end portion, and sometimes the corner may be caught on the underwear or the like, and the absorbent article may not be taken. 100 is pinched into the lower jaw. On the other hand, in the present embodiment, since the absorbent body 10 is formed into a circular shape, the edge below the front end portion in the depth direction and the edge below the rear end portion are formed in an arc shape, so that it is not caught on the clothes when worn, and can be smoothly performed. Wear it off. In addition, the outer shape of the absorbent body 10 may be a rectangular shape (fourth embodiment) or a circular shape (sixth embodiment), and may be appropriately changed in accordance with the use of the absorbent article 100.

[10. Seventh Embodiment]

Next, a seventh embodiment of the absorbent article 100 according to the present invention will be described with reference to Figs. 29 to 33. The seventh embodiment is the same as the above-described embodiment, and the description thereof is omitted, and the structure different from the above-described embodiment will be mainly described.

Fig. 29 is a perspective view showing an outline of an absorbent article 100 according to the present invention. As shown in Fig. 29, the absorbent article 100 according to the present invention is formed into a cylindrical three-dimensional shape having a space 4 therein. In the present embodiment, the back sides of the both ends of the flat rectangular absorbent body 10 are joined together to form a cylindrical shape having a space 4 extending in the depth direction (D). The absorptive body 10 forming a three-dimensional shape has a top surface portion 1 having a plane abutting against a lower jaw of the wearer, left and right side surface portions 2, 3 (left side surface portion 2 and right side surface portion 3), and the like from the top surface portion 1 The left and right sides extend toward the skin non-opposing surface side; and the space 4 is formed between the left and right side portions 2, 3. This space 4 is worn from The end of the ventral side to the end of the back side penetrates in the depth direction (D). Further, a liquid-impermeable leakage preventing sheet 20 is attached to the lower end portion 5 of the left and right side surface portions 2, 3 of the absorbent body 10. The leakage preventing sheet 20 is joined to the left and right side surface portions 2 and 3, and also functions to connect the side surface portions 2 and 3. Further, a through hole 7 connected to the internal space 4 is formed on the top surface portion 1 of the absorbent body 10.

Fig. 30 is an exploded perspective view showing the absorbent article 100, and Fig. 31 is a cross-sectional view showing the absorbent article. As shown in Fig. 29 to Fig. 31, the absorbent article 100 is provided with an absorbent main body 10 and a leakage preventing sheet 20 attached to the lower portion thereof.

As shown in Fig. 30, the absorber 13 is formed with a lattice-like pressing line 41 at least on the top surface portion 1. The extrusion line 41 is a linear recess formed by partially compressing the absorber 13. Further, the lattice shape refers to a state in which a plurality of extruded line groups extending in a certain direction intersect with a plurality of extruded line groups extending in a direction different from the line group. As shown in Fig. 30 and the like, the extrusion line 41 may be formed in a diagonal square lattice pattern, or may be formed in a square lattice pattern. In other words, the lattice-shaped extruded line 41 includes at least a person extending in the width direction (W) of the absorbent article or extending in a direction inclined in the range of 1 to 45 degrees in the width direction (W). For example, the angle (θ) at which the extrusion line 41 is inclined in the width direction of the absorbent article can be set to a range of 0 to 45 degrees, particularly preferably 30 to 45 degrees or 35 to 45 degrees.

Further, the extrusion line 41 can be basically formed by compressing the absorber 13 from the opposite side of the skin. However, the extrusion line 41 may be formed by compressing the absorbent body 13 from the non-opposing surface side of the skin, or may be formed by compressing the absorbent body 13 from both sides of the skin opposing surface and the skin non-opposing surface. As described above, since the extrusion line 41 is formed by compressing the absorber 13, the strength of the absorber 13 is increased at the portion (the top surface portion 1) where the extrusion line 41 is formed. In particular, as previously mentioned, the lattice-like absorber 13 is included along The width direction (W) of the absorbent article is extended or extended in a direction inclined in a predetermined range with respect to the width direction (W). Therefore, the absorber 13 can be said to have a portion where the top surface portion 1 of the extrusion line 41 is formed, and stress against an external force from the width direction can be increased.

As shown in Figs. 29 and 30, the stress of the top surface portion 1 is increased by forming the lattice-shaped pressing line 41 on the absorber 13 at a portion corresponding to the top surface portion 1 of the absorbent article 100. Therefore, even if the absorbent article 100 is sandwiched between the wearer's feet, the shape of the top surface portion 1 can be maintained, and the space 4 between the left and right side portions 2, 3 can be held. Thereby, the absorbent article 100 is more easily combined with the lower jaw and the inner thigh of the wearer. Further, by forming the lattice-shaped pressing line 41 on the top surface portion 1 of the absorber 13, the body fluid that touches the top surface portion 1 easily spreads along the pressing line 41. Thereby, the body fluid can be quickly absorbed from the top surface portion 1 over the side portions 2, 3 over a wide range, so that the effect of preventing leakage of urine can be improved.

Further, in the examples shown in Figs. 29 and 30, the pressing line 41 is formed only in the top surface portion 1 of the absorbent body 13. However, in the present invention, the extrusion line 41 may be formed at least on the top surface portion 1, and may be formed on the left and right side surface portions 2, 3, or may be formed on the entire absorbent body 13.

The outer sheet 11, the inner sheet 12, and the absorber 13 are bonded together in an unfolded state as shown in Fig. 30 to form the absorbent body 10, and the left and right ends of the absorbent body 10 in the width direction (W) are inward. The face sheet 12 is bent sideways, and its lower end portion is fitted with the leakage preventing sheet 20. Thereby, the absorbent article 100 including the absorbent main body 10 and the leakage preventing sheet 20 has a cylindrical three-dimensional shape as shown in FIG. Further, as shown in Fig. 31, the leakage preventing sheet 20 is attached to the lower end portion 5 of the absorbent main body 10 so as to extend across the left side surface portion 2 and the right side surface portion 3. Therefore, the leakage preventing sheet 20 can be said to be responsible for joining the left side surface 2 and the right side of the absorbent body 10. The function of the department 3.

Further, as shown in Figs. 29 and 30, the through hole 7 is preferably formed in a region of the top surface portion 1 in which the lattice-like pressing line 41 is formed. That is, in a state where the through hole 7 is surrounded by the pressing line 41, it is preferable that the pressing line 41 reaches the periphery of the through hole 7. That is, as shown in a part of the enlarged view of Fig. 30, the extrusion line 41 reaches the edge of the through hole 7, and a concave portion is also formed at the edge of the through hole 7. Further, as described above, since the strength of the absorber 13 is increased in the region where the extrusion line 41 is formed, the through hole 7 can be held by the through hole 7 in the region of the grid-like extrusion line 41. shape. In the present invention, as described above, by providing the lattice-shaped pressing line 41 on the top surface portion 1, the rigidity is increased in the width direction of the top surface portion 1 to prevent deformation. Therefore, even if the through hole 7 is provided in the top surface portion 1, the through hole 7 does not cause clogging by the action of the pressing wire 41, and the function as a hole can be exhibited.

As described above, the through hole 7 is formed on the outer sheet 11, the inner sheet 12, and the absorber 13 which constitute the entire top surface portion 1. Therefore, in order to prevent the contents of the absorbent body 13 from coming out of the edge of the through hole 7, it is preferable to join the outer sheet 11 and the inner sheet 12 in the through hole 7 along the contour of the through hole 7 as shown in Fig. 31. . Thereby, the exposure of the absorber 13 can be prevented.

Fig. 32 is a view showing an example of a state in which the absorbent article 100 is sandwiched between the wearer's lower jaw. As shown in Fig. 32, the top surface portion 1 of the absorbent body 10 which forms a flat surface is in close contact with the lower jaw of the wearer, and the side surface portions 2, 3 on the left and right sides thereof are in close contact with the inner thigh of the wearer. Further, since the space 4 is held between the left and right side surface portions 2, 3, the absorbent body 10 as a whole has high cushioning property, and the adhesion state to the lower jaw and the inner thigh can be maintained. Thereby, a gap is not formed between the absorbent body 10 and the wearer's skin, even in the case of wearing a wearer in a lateral or semi-recumbent posture, it can be effectively prevented. Leakage from the top surface 1 side or the side surface portions 2, 3 side. Further, since the leakage preventing sheet 20 is added to the lower end portion 5 of the absorbent body 10, it is possible to avoid the soiling of the underwear, the sheets, or the disposable diaper which is used after being worn. Further, when the absorbent article 100 is exchanged, the leakage preventing sheet 20 is taken out as a handle, and the exchange work can be easily performed without soiling the hand.

Figs. 33(a) to 33(e) are diagrams showing an example of a manufacturing procedure of the absorbent article 100 according to the seventh embodiment. In Fig. 33, a cross-sectional view of each of the XXXIII-XXXIII lines is shown. The absorbent article 100 can be manufactured in accordance with the steps shown in Figs. 33(a) to 33(e). In other words, first, the rectangular outer sheet 11 is prepared, and the rectangular absorber 13 in which the through hole 7 and the lattice-shaped pressing line 41 are formed is placed on the skin non-opposing surface side of the outer sheet 11 (Fig. 33(a)) . Further, at this time, the through hole 7 is not formed on the outer sheet 11. Next, the inner sheet 12 is placed on the skin non-opposing surface side of the absorber 13 (Fig. 33(b)). At this time, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. Further, the absorber 13 may be joined to either or both of the outer sheet 11 and the inner sheet 12. Thereby, the absorbent body 10 can be obtained. Further, at this stage, the through hole 7 is not formed on the outer sheet 11. Next, the absorbent body 10 is folded in half toward the inner sheet 12 along the through hole 7 formed in the absorber 13 (Fig. 33(c)). In other words, the outer sheet 11 is folded outward and the inner sheet 12 is inside. At this time, the through hole 7 of the absorber 13 is located at the apex of the fold. Thereafter, the through hole 7 of the absorber 13 positioned at the apex portion is cut away, and the through hole 7 having substantially the same shape as the absorber 13 is formed on the outer sheet 11 and the inner sheet 12 (Fig. 33(d)) . At this time, since the outer sheet 11 and the inner sheet 12 overlap with the through hole 7 of the absorber 13, the outer sheet 11 and the inner sheet 12 are cut by the same position as the through hole 7 of the absorber 13. Then, the through hole 7 can be formed substantially simultaneously on both the outer sheet 11 and the inner sheet 12. Thereafter, under the equivalent of the absorbent body 10 The leakage preventing sheet 20 is joined at the position of the end portion (Fig. 33(e)). Further, the step of forming the chevron 8 at an appropriate position of the absorbent body 10 constituting the absorbent article 100 may be added. Further, a step of the end portion on the side opposite to the apex of the folded edge (that is, the end portion on the side of the leakage preventing sheet 20) may be added with a hot-melt adhesive or the like.

According to the above manufacturing steps, the absorbent article 100 in which the through holes 7 are formed can be efficiently manufactured. Further, as shown in Fig. 33(c), after the through hole 7 is formed in the absorber 13, the entire absorbent body 10 is folded in half along the through hole 7, and the top surface attached to the absorbent body 10 can be attached. The fold on 1 is limited to a minimum. That is, as described above, the top surface portion 1 preferably has a flat surface and does not have any wrinkles, but forms a fold which must be generated at the time of manufacture along the through hole 7, and the wrinkle attached to the top surface portion 1 can be minimized. Thereby, it is also possible to form a state in which the fold hardly remains on the top surface portion 1 at the time of wearing.

[11. Eighth Embodiment]

Next, an eighth embodiment of the absorbent article 100 of the present invention will be described with reference to Figs. 34 to 36. The eighth embodiment is the same as the above-described embodiment, and the description thereof is omitted, and the structure different from the above-described embodiment will be mainly described.

Fig. 34 is an exploded perspective view showing the absorbent article 100 according to the eighth embodiment, and Fig. 35 is a cross-sectional view showing the absorbent article 100 according to the eighth embodiment. As shown in Figs. 34 and 35, the absorbent article 100 according to the eighth embodiment further includes a sub-absorbent body 14 in addition to the constituent elements described in the seventh embodiment.

As shown in Fig. 35, in the present embodiment, the sub-absorbent body 14 is disposed on the top surface portion 1 of the absorbent main body 10. In particular, the sub-absorbent body 14 is disposed on the skin non-opposing surface side of the absorber 13 (hereinafter also referred to as "main absorber"), that is, between the main absorber 13 and the inner sheet 12. Further, the sub absorber 14 is the same as the main absorber 13, and is made of an absorbent material 14a. It may be configured with the core wrap sheet 14b. According to the present embodiment, the main absorbent body 13 and the sub-absorbent body 14 are superposed on the top surface portion 1, and the amount of absorption of the body fluid by the top surface portion 1 is increased. Therefore, this embodiment can be said to be a form suitable for a woman who has a large amount of body fluid directly contacting the top surface portion 1. Further, when the sub-absorbent body 14 is disposed on the top surface portion 1, the through-holes 7 are also formed in the sub-absorbent body 14. By providing the main absorber 13 and the sub-absorber 14 on the top surface portion 1 in a two-layer structure, the rigidity is further increased in the width direction, and the blocking of the through hole 7 can be prevented. Further, although not shown in the drawings, the sub-absorbent body 14 may be disposed on the skin facing surface side of the main absorbent body 13, that is, between the absorber 13 and the outer sheet 11. In the present embodiment, the sub-absorbent body 14 may be disposed at least on the top surface portion 1, or may be disposed on the left and right side surface portions 2, 3. However, as in the embodiment shown in Fig. 35, the sub-absorbent body 14 is preferably disposed only on the top surface portion 1.

Fig. 36 (a) and (b) show the main absorber 13 and the sub absorber 14 in a separate manner, and Fig. 36 (c) and (d) show the cross-sectional shape of XXXVI-XXXVI. Further, Fig. 37 is a view showing a state in which the main absorbent body 13 and the sub-absorbent body 14 are overlapped, and the pattern of the extrusion line 41 formed on the main absorbent body 13 and the extrusion line 51 formed on the sub-absorbent body 14 are enlarged. Pattern of the pattern. Further, in Figs. 36 and 37, only the main absorbent body 13 and the sub-absorbent body 14 are conceptually drawn for display.

As shown in Fig. 36 and Fig. 37, in the eighth embodiment, a plurality of the respective absorbers 13 and 14 are recessed in the thickness direction in the respective absorbers of the main absorber 13 and the sub absorber 14. The lines 41, 51 are extruded. That is, the plurality of extrusion lines 41 and 51 are formed on the respective absorbers of the main absorbent body 13 and the sub-absorbent body 14. The extrusion lines 41 and 51 are formed by partially compressing and compressing the respective extrusion lines 41 and 51 from both sides or either side of the skin facing surface side and the skin non-opposing surface side. Therefore, the density of the absorbent materials 13a and 14a of the respective absorbers 13 and 14 is increased at the portions where the extrusion lines 41 and 51 are formed. Moreover, the extrusion line formed on the main absorber 13 When the extrusion line 51 formed on the sub-absorber 14 is viewed from the plane direction, a pattern at least partially intersecting each other is formed. Hereinafter, the pattern of the extrusion line 41 formed on the main absorber 13 and the pattern of the extrusion line 51 formed on the sub-absorber 14 will be described in detail.

As shown in Fig. 36, the extrusion line 41 is formed on the main absorbent body 13 in a diagonal square lattice pattern. Here, the "skewed square lattice pattern" refers to a pattern in which a plurality of extrusion lines extending in a direction inclined in the longitudinal direction and the width direction intersect with each other and a rhombic (diamond) non-extrusion region is divided. For example, as shown in Fig. 36, the angle (θ) at which the extrusion line is inclined in the width direction of the absorbent article can be set to a range of 1 to 45 degrees, and further preferably 30 to 45 degrees or 35 to 45 degrees. . In particular, in the present embodiment, the pattern of the extrusion line 41 on the main absorber 13 forms a regular pattern in which the non-extrusion regions 42 surrounded by the extrusion line 41 become a regular rhombic shape (a rhomboid shape) (a rhombic square) Grid pattern). In this manner, the main absorber 13 can be imagined as a plurality of extrusion lines 41, a non-extrusion region 42 surrounded by the extrusion line 41, and an intersection portion 43 where the extrusion line 41 intersects. Hereinafter, for the sake of convenience, the extrusion line 41 of the main absorbent body 13 is referred to as "upper extrusion line 41", the non-extrusion region 42 is referred to as "upper non-extrusion region 42", and the intersection portion 43 is referred to as "upper intersection" Part 43".

On the other hand, the extrusion line 51 is formed on the sub-absorbent body 14 in a square lattice pattern. Here, the "square lattice-like pattern" means a plurality of extrusion lines extending in parallel with the longitudinal direction and intersecting a plurality of extrusion lines extending in parallel with the width direction, and are divided into a non-extrusion region having a quadrangular shape. pattern. In particular, in the present embodiment, the pattern of the extrusion line 51 on the sub-absorber 14 is formed into a square regular pattern (a square grid-like pattern) in which all of the non-extrusion regions 52 surrounded by the extrusion line 51 are square. Thus, in the case of the sub-absorber 14, it is also conceivable that a plurality of extruded lines 51 are formed, and the extruded line 51 surrounds the surrounding non-extrusion. The intersection portion 53 where the pressing region 52 and the pressing line 51 intersect. Hereinafter, for the sake of convenience, the extrusion line 51 of the sub-absorber 14 is referred to as "lower extrusion line 51", and the non-extrusion area 52 is referred to as "lower non-extrusion area 52", and the intersection portion 53 is referred to as " Lower intersection point 53".

Further, in the present embodiment, the upper pressing line 41 is formed by being recessed by compressing the main absorbent body 13 from the skin facing surface side. Similarly, the lower pressing line 51 is formed by compressing the sub-absorbent body 14 from the skin facing surface side. Therefore, the portion where the lower extrusion line 51 is formed on the sub-absorber 14 is in a state in which the main absorber 13 and the sub-absorber 14 are superposed, and a gap is formed therebetween.

As shown in Fig. 37, in the present embodiment, the upper side intersection portion 43 of the main absorber 13 and the lower side intersection portion 53 of the sub absorber 14 are overlapped in a state in which the respective absorbers 13 and 14 are overlapped. Further, the overlap with the center (the intersection of the diagonal lines) of the lower non-extrusion region 52 of the sub-absorber 14 is present in the plurality of upper intersection portions 43 of the main absorber 13. In particular, in the range where the pattern of the upper side extrusion line 41 of the main absorbent body 13 overlaps with the pattern of the lower side extrusion line 51 of the sub absorber 14, the upper side intersection portion 43 exists in the range of all the lower side non-extrusion areas 52. Inside. Therefore, in the present embodiment, it is found that the upper extrusion line 41 overlaps with the position corresponding to the diagonal of the square-shaped lower non-extrusion region 52. Further, in the present embodiment, it is found that the lower pressing line 51 is overlapped in the range of the upper non-extrusion region 42.

Further, as shown in Fig. 36, the length D1 of the diagonal along the longitudinal direction of the upper non-extrusion region 42 (orthogonal square) and the length L of the lower non-extrusion region 52 (square) in the longitudinal direction are slightly equal ( D1=L). Further, the length D2 of the diagonal along the width direction of the upper non-extrusion region 42 (orthogonal square) and the length B of the lower non-extrusion region 52 (square) in the width direction are slightly equal (D2=B). Furthermore, the term "slightly" in the specification of the present specification means an error of ±5%. Meet these conditions, the upper side squeeze The pressing wire 41 overlaps with a position corresponding to a diagonal line forming a square-shaped lower non-extrusion region 52.

As described above, in the present embodiment, the lower pressing line 51 is overlapped in the range of the upper non-extrusion region 42, and the lower side of the upper extrusion line 41 and the upper intersection portion 43 are overlapped in the range of the non-extrusion region 52, and The upper intersection portion 43 and the lower intersection portion 53 overlap each other. Therefore, the body fluid diffused along the upper side extrusion line 41 of the main absorbent body 13 falls onto the sub-absorbent body 14 and is absorbed by the lower non-extrusion region 52. Further, the body fluid retained in the upper intersection portion 43 of the main absorbent body 13 falls onto the sub-absorbent body 14, and is diffused along the lower side extrusion line 51 by the lower intersection portion 53. Further, the body fluid diffused along the lower side extrusion line 51 of the sub-absorber 14 is absorbed by the upper non-extrusion region 42 of the main absorber 13. Further, the lower side extrusion line 51 may also diffuse the body fluid in the diagonal direction of the lattice pattern of the upper side extrusion line 41. Thereby, by forming such a pattern, the body fluid can be quickly guided by the non-extrusion regions 42, 52 which have been conventionally regarded as having a slow absorption time.

Here, specific values regarding constituent elements of the absorbent article will be described. For example, the thickness of each of the absorbers 13, 14, that is, the thickness of the non-extrusion regions 42, 52 is preferably 5 mm to 20 mm, and particularly preferably 8 mm to 15 mm. Further, the thickness of each of the absorbers 13 and 14 at the portion where the extrusion wires 41 and 51 are formed is preferably 1 mm to 10 mm, and particularly preferably 2 mm to 5 mm. However, of course, the thickness of the portion where the extrusion lines 41, 51 are formed is smaller than the thickness of the non-extrusion regions 42, 52. For example, the thickness of the portion where the extruded wires 41, 51 are formed is 3% to 50%, particularly preferably 5% to 20%, for the thickness of the non-extrusion regions 42, 52.

Further, the width of each of the extrusion lines 41, 51 is preferably from 1 mm to 5 mm, particularly preferably from 2 mm to 4 mm. Further, the length D1 of the diagonal line in the longitudinal direction of the upper non-extrusion region 42 shown in Fig. 36 is preferably 10 mm to 50 mm, particularly preferably 20 mm to 40 mm or 30 mm. The length D2 of the diagonal line in the width direction of the upper non-extrusion region 42 The preferred range of values is the same as the length D1 described above. The length D1 and the length D2 are preferably slightly equal, but may be different. That is, the shape of the upper non-extrusion region 42 is not limited to a rhombic shape (a rhomboid shape), and may be another rhombic shape. Further, the length L of the lower non-extrusion region 52 shown in Fig. 36 is preferably 10 mm to 50 mm, particularly preferably 20 mm to 40 mm or 30 mm. The preferred numerical range of the width B of the lower non-extrusion region 52 is the same as the aforementioned length L. The length L and the width B are preferably slightly equal, but may be different. That is, the shape of the lower non-extrusion region 52 is not limited to a square shape, and may be another square shape. As described above, although the length D1 and the length L are slightly equal, and the length D2 and the width B are slightly equal to each other, the present invention is not limited thereto.

It is preferable that the extrusion lines 41 and 51 formed on each of the absorbers 13 and 14 are formed over a wide range in the longitudinal direction so that the body fluid discharged to the vicinity of the lower jaw portion can be widely diffused to the front body and the back body. Specifically, the length of the region in which the extrusion lines 41 and 51 are formed in the longitudinal direction is preferably 60% or more, and 60% to 100%, 70% to 100, in the longitudinal direction of each of the absorbers 13 and 14. % or 80%~100% is especially good. Further, it is preferable that the extrusion lines 41 and 51 formed on the respective absorbers 13 and 14 are formed over a wide range in the width direction so that the body fluid discharged to the vicinity of the center in the width direction is widely spread to the outside in the width direction. Specifically, the maximum width in the width direction of the region in which the upper extrusion line 41 is formed is 60% or more, and 60% to 100%, 70%, in the width direction of the top surface portion 1 of the main absorbent body 13. ~100% or 80%~100% is especially good. Further, the maximum width in the width direction of the region in which the lower extrusion line 51 is formed is 60% or more, and is 60% to 100%, 70% to 100% or 80, in the width direction of the sub-absorber 14. %~100% is especially good.

Further, in the figure, the extruded lines 41, 51 are shown by the absorbent materials 13a, 14a and the core pack constituting the respective absorbent bodies 13, 14. An example in which both of the covering sheets 13b and 14b are recessed. However, the extrusion lines 41, 51 may be formed by at least recessing the absorbent material 13a, 14a to be recessed. That is, after the extruded wires 41, 51 are formed by compressing the absorbent materials 13a, 14a, the core covering sheets 13b, 14b are joined to coat the absorbent materials 34, 44. In this sense, it is sufficient that the extrusion lines 41, 51 are formed on the absorbent materials 13a, 14a constituting the respective absorbers 13, 14.

[12. Ninth Embodiment]

Next, an absorbent article according to a ninth embodiment of the present invention will be described with reference to Figs. 38 and 39. The ninth embodiment is the same as the above-described embodiment, and the description thereof is omitted, and the structure different from the above-described embodiment will be mainly described.

Fig. 38 (a) and (b) show the main absorber 13 separated from the sub absorber 14, and Fig. 38 (c) and (d) show the cross-sectional shape of XXXVIII-XXXVIII. Further, Fig. 39 is a view showing a state in which the main absorbent body 13 and the sub-absorbent body 14 are overlapped, and the pattern of the extrusion line 41 formed on the main absorbent body 13 and the extrusion line 51 formed on the sub-absorbent body 14 are enlarged. Pattern of the pattern. Further, Figs. 38 and 39 show conceptually only the main absorbent body 13 and the secondary absorbent body 14 are drawn.

In the ninth embodiment, the patterns of the extrusion lines 41 and 51 formed on the respective absorbers 13 and 14 are different from those of the eighth embodiment. As shown in Figs. 38 and 39, the main absorber 13 forms the upper extrusion line 41 in a square lattice pattern, and the sub absorber 14 forms the lower extrusion line 51 in a pattern of a square oblique grid. The orthorhombic grid-like pattern and the square grid-like pattern referred to here are substantially the same as those described in the eighth embodiment. In the ninth embodiment, in a state in which the main absorber 13 and the sub-absorber 14 are superposed, a square lattice pattern formed on the main absorber 13 and a square lattice pattern formed on the sub-absorber 14 are formed. The relative positional relationship of the pattern and the eighth implementation Different forms.

As is apparent from the respective drawings, in the ninth embodiment, the area of the upper non-extrusion region 42 is larger than the area of the lower non-extrusion region 52. Therefore, when the main absorber 13 and the sub absorber 14 are overlapped, the lower non-extrusion area 52 (orthogonal square) is accommodated in the range of the upper non-extrusion area 42 (square).

Further, in the ninth embodiment, the four lower side intersection portions 53 of the lower non-extrusion region 52 (forward rhombic) are defined as the upper sides of the four sides of the upper non-extrusion region 42 (square). The extrusion lines 41 overlap. Therefore, as shown in Fig. 39, it is found that the lower non-extrusion region 52 (orthogonal square) is just accommodated in the range of the upper non-extrusion region 42 (square). That is, the center of the upper non-extrusion region 42 (square) (the intersection of the diagonal lines) coincides with the center of the lower non-extrusion region 52 (the oblique square) (the intersection of the diagonal lines). Further, as shown in Fig. 38, the length L of the longitudinal direction of the upper non-extrusion region 42 (square) and the length D1 of the diagonal along the longitudinal direction of the lower non-extrusion region 52 (forward oblique) Slightly equal (L=D1). Further, the length B of the upper non-extrusion region 42 (square) in the width direction and the length D2 of the diagonal along the width direction of the lower non-extrusion region 52 are slightly equal (B=D2). When these conditions are satisfied, the four lower side intersection portions 53 defining the lower side non-extrusion region 52 (forward rhombic) are respectively the upper side extrusion lines 41 which define the four sides of the upper side non-extrusion region 42 (square). overlapping.

Further, as shown in Fig. 39, the upper intersection portion 43 overlaps with the center (the intersection of the diagonal lines) of the lower non-extrusion region 52 (orthogonal square), respectively. When viewed from different angles, the upper side intersection portion 43 overlaps with the upper side intersection portion 43 and is present in a plurality of lower non-extrusion regions 52 (orthogonal squares). In the example shown in Fig. 39, it is known that among the plurality of rows of the lower non-extrusion region 52, the row in which the upper intersection portion 43 overlaps and the upper intersection portion 43 do not overlap each other alternately. . same In the plural column of the lower non-extrusion region 52, the column in which the upper intersection portion 43 overlaps and the upper intersection portion 43 do not overlap each other alternately.

As described above, by forming the pattern of the upper side extrusion line 41 (square lattice shape) and the pattern of the lower side extrusion line 51 (orthogonal square lattice shape), even if the extrusion line is not densely formed on one absorber, The body fluid can be effectively diffused into the non-extrusion region, and the body fluid can be absorbed over a wide range of the entire absorbent body of the two layers. That is, the body fluid diffused along the upper extrusion line 41 of the main absorbent body 13 is absorbed by the lower non-extrusion region 52 of the sub-absorbent body 14. Therefore, the body fluid diffused along the upper side extrusion line 41 of the main absorbent body 13 does not reach the end portion, and the leakage to the outside can be effectively prevented. Further, since the body fluid can be absorbed in a wide range of the two layers of the absorbent bodies 13, 14, the amount of absorption of the body fluid is improved, and the wearer is not unpleasant even if worn for a long period of time. In the intersection portions 43 and 53 formed on the respective absorbers 13 and 14, since the extrusion lines 41 and 51 intersect, the body fluid tends to stay. By overlapping the upper intersection portion 43 of the main absorbent body 13 with the lower non-extrusion region 52 of the sub-absorbent body 14, the body fluid retained in the upper intersection portion 43 can be effectively infiltrated into the lower non-extrusion region 52. .

Further, in the ninth embodiment, the row and the row of the lower non-extrusion regions 52 in which the upper intersection portion 43 is overlapped are formed in every other row and every other row, so that the body fluid permeating the main absorber 13 can be diffused to more. Far area. Therefore, the body fluid permeating into the main absorbent body 13 can be diffused and infiltrated into a wide range of the sub-absorbent body 14.

Further, the extrusion line has a function of flowing a liquid as a groove and diffusing the liquid along the pressing portion to a non-extrusion region around the pressing portion by capillary action. Even when it is used in a functional form as a groove, the liquid is allowed to be transferred from the extrusion line of one of the absorbent bodies to the extrusion line or the non-extrusion area of the other absorbent body. The reason is as follows. That is, the extrusion line deforms the absorbent material constituting the absorbent body by pressure. Therefore, the absorbent body absorbs the liquid at the portion where the extrusion line is formed, and the thickness changes. That is, in the pulp of the extrusion line or the SAP-absorbent, the interval between the pulps will relax as the use time increases, and the SAP will swell, so the extrusion line will gradually become shallower, and finally the thickness will be different from that after swelling. The squeezing area is approximately the same. Thus, even if the extrusion line has a depth before absorption, the depth will gradually become shallow as the liquid absorption proceeds. Therefore, it is easy to impart a liquid to the extrusion line or the non-extrusion area of the absorbent body of the other one of the absorbers of the other. That is, since the extrusion line forms a groove in the initial state, the liquid preferentially flows into the extrusion line. Then, the portion where the extrusion line is formed is subjected to liquid absorption, and the extrusion line is swollen, so as described above, the liquid is squeezed onto the absorbent body of the other one overlapping the swollen extrusion line. The line or non-extrusion area moves.

As described above, the pattern of the ninth embodiment can be said that the diffusion range of the body fluid is wider than that of the pattern of the eighth embodiment. On the other hand, the pattern of the eighth embodiment can be said that the absorption rate of the body fluid is faster than that of the pattern of the ninth embodiment. Therefore, in the case where the extrusion line is formed on each of the absorbers of the two layers of the absorbent body, any pattern of the pattern of the eighth embodiment and the pattern of the ninth embodiment is used, and the performance required for the absorbent article is considered. Just decide it properly.

Further, the width D1 of the respective extrusion lines 41, 51, the length D1 of the diagonal in the longitudinal direction of the upper non-extrusion region 42, the length D2 of the diagonal in the width direction, or the length direction of the lower non-extrusion region 52 The value of the length L or the width B is preferably set to the same range as the above-described eighth embodiment.

[13. Tenth Embodiment]

Next, a tenth embodiment of the absorbent article 100 of the present invention will be described with reference to Figs. 40 to 44. The tenth embodiment is the same as the above-described embodiment, and the description is omitted. It is to be noted that the structure different from the above-described embodiment will be mainly described.

Fig. 40 is a perspective view showing an outline of an absorbent article 100 according to the present invention. As shown in Fig. 40, the absorbent article 100 according to the present invention is formed into a cylindrical three-dimensional shape having a space 4 therein. In the present embodiment, the back sides of the both ends of the flat rectangular absorbent body 10 are joined together to form a cylindrical shape having a space 4 extending in the depth direction (D). The absorptive body 10 forming a three-dimensional shape has a top surface portion 1 having a plane abutting against a lower jaw of the wearer, left and right side surface portions 2, 3 (left side surface portion 2 and right side surface portion 3), and the like from the top surface portion 1 The left and right sides extend toward the skin non-opposing surface side; and the space 4 is formed between the left and right side portions 2, 3. This space 4 penetrates from the end of the wearer's ventral side to the end of the back side, and penetrates in the depth direction (D). Further, a liquid-impermeable leakage preventing sheet 20 is attached to the lower end portion 5 of the left and right side surface portions 2, 3 of the absorbent body 10. The leakage preventing sheet 20 is joined to the left and right side surface portions 2 and 3, and also functions to connect the side surface portions 2 and 3. Further, a through hole 7 connected to the internal space 4 is formed on the top surface portion 1 of the absorbent body 10.

Fig. 41 is an exploded perspective view showing the absorbent article 100, and Fig. 42 is a sectional view showing the absorbent article. As shown in FIGS. 40 to 42, the absorbent article 100 is provided with an absorbent body 10 and a leakage preventing sheet 20 attached to the lower portion thereof.

As shown in Figs. 40 and 41, the absorber 13 is formed with a plurality of extrusion lines 41 at least on the left and right side portions 2, 3. The extrusion line 41 is a linear recess formed by partially compressing the absorber 13. The plurality of extruded lines are preferably a plurality of parallel extruded lines or a plurality of extruded lines defining a closed area. In addition, a plurality of extrusion lines are particularly preferred for a plurality of parallel extrusion lines defining the enclosed area. In the embodiment shown in Fig. 40 and Fig. 41 and the like, the extrusion line 41 is formed in a lattice shape. In addition, the so-called lattice shape refers to a plurality of extrusion lines extending in a certain direction. The group intersects with a plurality of extruded line groups extending in different directions from the line group. The extrusion line 41 may be formed in a diagonal square lattice pattern as shown in FIG. 41 or the like, or may be formed in a square lattice pattern. In other words, the lattice-shaped extrusion line 41 includes, as shown in Fig. 41, when the absorber 13 is expanded into a planar shape, extending along the width direction (W) of the absorbent article or along the width direction (W) ) extends in the direction of inclination from 1 to 45 degrees. For example, the angle (θ) at which the extrusion line 41 is inclined in the width direction of the absorbent article can be set to a range of 0 to 45 degrees, particularly preferably 30 to 45 degrees or 35 to 45 degrees.

Further, the extrusion line 41 can be basically formed by compressing the absorber 13 from the opposite side of the skin. However, the extrusion line 41 may be formed by compressing the absorbent body 13 from the non-opposing surface side of the skin, or may be formed by compressing the absorbent body 13 from both sides of the skin opposing surface and the skin non-opposing surface. Since the extrusion line 41 is a portion that compresses the absorber 13 in this manner, the strength of the absorber 13 is improved at the portion (the left and right side portions 2, 3) where the extrusion line 41 is formed.

As shown in Fig. 40 and Fig. 41, by forming the lattice-like pressing line 41 on the left and right side surface portions 2, 3 of the absorbent body 13, the body fluid contacting or infiltrating into the left and right side portions 2, 3 will follow. This extrusion line 41 spreads. Thereby, the body fluid can be quickly absorbed over a wide range of the side portions 2, 3, so that the effect of preventing leakage of urine can be improved. Further, in the portion corresponding to the left and right side surface portions 2, 3 of the absorbent article 100, the lattice-shaped pressing line 41 is formed on the absorbent body 13, so that the stress of the left and right side surface portions 2, 3 becomes strong. Therefore, even if the absorbent article 100 is sandwiched between the wearer's feet, the shape of the top surface portion 1 can be maintained, and the space 4 between the left and right side portions 2, 3 can be held. Thereby, the absorbent article 100 is more easily combined with the lower jaw and the inner thigh of the wearer.

Further, in the examples shown in Figs. 40 and 41, the extrusion line 41 is formed only in the left and right side surface portions 2, 3 of the absorbent body 13. Of course Further, in the present invention, the extrusion line 41 may be formed not only on the left and right side surface portions 2, 3 but also on the top surface portion 1, or may be formed on the entire absorbent body 13.

The outer sheet 11, the inner sheet 12, and the absorber 13 are bonded together in an unfolded state as shown in Fig. 41 to form the absorbent body 10, and the left and right ends of the width direction (W) of the absorbent body 10 are inward. The face sheet 12 is bent sideways, and its lower end portion is fitted with the leakage preventing sheet 20. Thereby, the absorbent article 100 including the absorbent main body 10 and the leakage preventing sheet 20 has a cylindrical three-dimensional shape as shown in Fig. 42. Further, as shown in Fig. 42, the leakage preventing sheet 20 is attached to the lower end portion 5 of the absorbent main body 10 so as to extend across the left side surface portion 2 and the right side surface portion 3. Therefore, the leakage preventing sheet 20 can be said to be responsible for the function of joining the left side surface portion 2 and the right side surface portion 3 of the absorbent body 10.

Further, as shown in Figs. 40 to 42, the lattice-like pressing line 41 is preferably formed on the liquid absorbing portion 6 in which at least the leakage preventing sheet 20 is not attached to the left and right side surface portions 2, 3. By providing the lattice-like pressing line 41 on the liquid-absorbent portion 6, it is possible to prevent the pressing line 41 from being hidden on the back surface of the leakage preventing sheet 20. Thereby, the body fluid adhering or infiltrating into the liquid absorbing portion 6 spreads along the extrusion line 41 to a wide range. Further, it is preferable that the extrusion line 41 is formed not only by the liquid absorbing portion 6, but also from the liquid absorbing portion 6 through the lower end portion 5 to which the leakage preventing sheet 20 is attached. That is, the lattice-like pressing line 41 preferably extends beyond the edge of the leakage preventing sheet 20 and continuously extends from the liquid-absorbent portion 6 to the lower end portion 5. Thus, by providing the pressing line 41 to be connected from the liquid-absorbent portion 6 to the lower end portion 5, the body fluid absorbed by the liquid-absorbent portion 6 can be quickly introduced into the lower end of the back surface of the leak-proof sheet 20 by the extrusion line 41. Department 5. Since the lower end portion 5 is hidden on the back surface of the leakage preventing sheet 20, the body fluid does not penetrate into the lower end portion 5, but the pressing line 41 functions as a flow path for transporting the body fluid to the lower end portion 5. Thereby, the body fluid can be further diffused to a wide range.

Further, as shown in Fig. 40, in the present embodiment, the left and right side surface portions 2, 3 are divided into a region in which the lattice-shaped extrusion line 41 is formed, that is, the extrusion line forming region 6a, and the extrusion line 41 is not formed. The area is the extruded line non-formed area 6b. In the present embodiment, the extrusion line forming region 6a is provided on the lower end sides of the left and right side surface portions 2, 3, and the extrusion line non-formation region 6b is provided in the top surface portion 1 (the mountain-shaped fold 8) and the extrusion line forming region 6a. between. Since the extrusion line forming region 6a is partially compressed by the absorbent body 13, the skin feel is slightly hardened. On the other hand, the extruded line non-formation region 6b does not have the pressing line 41, and the skin feels relatively soft. Therefore, by providing the pressing line 41 between the top surface portion 1 and the pressing line forming region 6a, the skin feel of the absorbent article 100 in contact with the hip joint of the wearer can be improved. Thereby, the wearing feeling of the absorbent article 100 is improved. Further, even if the region where the extrusion line 41 is formed is limited to the lower end sides of the left and right side portions 2, 3, the body fluid permeating the absorber 13 flows downward with gravity, so that it finally reaches the extrusion line forming region. 6a. Then, the body fluid reaching the extrusion line forming region 6a spreads widely along the extrusion line 41. As described above, in the present invention, the extrusion line non-formation region 6b is provided on the upper side of the left and right side surface portions 2, 3, and the extrusion line formation region 6a is provided on the lower side. Thereby, while maintaining the diffusibility of the body fluid, the stimulation of the wearer's skin is reduced as compared with the case where the extrusion line is formed on, for example, the entire left and right side portions 2, 3, and the skin feel can be improved.

Further, the length of the extrusion line non-formation region 6b in the height direction (H) is preferably 20% or more for the entire length of the left and right side portions 2, 3 in the height direction (H). Specifically, the length of the extrusion line non-formation region 6b in the height direction (H) is preferably 20 to 70%, more preferably 30 to 50%. As described above, by ensuring a certain range or more of the range of the extruded line non-formation region 6b, it is possible to improve the comfort of the skin touch to the portion near the hip joint of the wearer.

Figure 43 is a view showing the sandwiching of the absorbent article 100 An example of the state of the person's jaw. As shown in Fig. 43, the top surface portion 1 of the absorbent body 10 which forms a flat surface is in close contact with the lower jaw of the wearer, and the side surface portions 2, 3 on the left and right sides thereof are in close contact with the inner thigh of the wearer. Further, since the space 4 is held between the left and right side surface portions 2, 3, the absorbent body 10 as a whole has high cushioning property, and the adhesion state to the lower jaw and the inner thigh can be maintained. Thereby, a gap is not generated between the absorbent body 10 and the wearer's skin, even in the case of wearing the wearer in the lateral or semi-recumbent posture, it is possible to effectively prevent the side from the top face 1 or Leakage of urine on the side portions 2, 3 side. Further, since the leakage preventing sheet 20 is added to the lower end portion 5 of the absorbent body 10, it is possible to avoid the soiling of the underwear, the sheets, or the disposable diaper which is used after being worn. Further, when the absorbent article 100 is exchanged, the leakage preventing sheet 20 is taken out as a handle, and the exchange work can be easily performed without soiling the hand.

44(a) to 44(e) are diagrams showing an example of a manufacturing procedure of the absorbent article 100 according to the tenth embodiment. In Fig. 44, a cross-sectional view of each XLIV-XLIV line is shown. The absorbent article 100 can be manufactured in accordance with the steps shown in Figs. 44(a) to 44(e). In other words, first, a rectangular outer sheet 11 is prepared, and a rectangular absorber 13 having a through hole 7 and a lattice-shaped extruded line 41 is placed on the skin non-opposing surface side of the outer sheet 11 (Fig. 44 (a) ). Further, at this time, the through hole 7 is not formed on the outer sheet 11. Next, the inner sheet 12 is placed on the skin non-opposing surface side of the absorber 13 (Fig. 44(b)). At this time, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. Further, the absorber 13 may be joined to either or both of the outer sheet 11 and the inner sheet 12. Thereby, the absorbent body 10 can be obtained. Further, at this stage, the through hole 7 is not formed on the outer sheet 11. Next, the absorbent body 10 is folded in the inner peripheral sheet 12 side along the through hole 7 formed in the absorbent body 13 (Fig. 44 (c)). In other words, the outer sheet 11 is folded outward and the inner sheet 12 is inside. At this time, absorption The through hole 7 of the body 13 is located at the apex of the fold. Thereafter, the through hole 7 of the absorber 13 positioned at the apex portion is cut away, and the through hole 7 having substantially the same shape as the absorber 13 is formed on both the outer sheet 11 and the inner sheet 12 (Fig. 44 (d)) . At this time, since the outer sheet 11 and the inner sheet 12 overlap with the through hole 7 of the absorber 13, the outer sheet 11 and the inner sheet 12 are cut by the same position as the through hole 7 of the absorber 13. Then, the through hole 7 can be formed substantially simultaneously on both the outer sheet 11 and the inner sheet 12. Thereafter, the leakage preventing sheet 20 is joined at a position corresponding to the lower end portion of the absorbent body 10 (Fig. 44(e)). At this time, the leakage preventing sheet 20 partially covers the region where the extrusion line 41 is formed (the extrusion line forming region 6a). Further, the step of forming the chevron 8 may be added to an appropriate position of the absorbent body 10 constituting the absorbent article 100. Further, a step of the end portion on the side opposite to the apex of the folded edge (that is, the end portion on the side of the leakage preventing sheet 20) may be added with a hot-melt adhesive or the like.

According to the above manufacturing steps, the absorbent article 100 in which the through holes 7 are formed can be efficiently manufactured. Further, as shown in FIG. 44(c), after the through hole 7 is formed in the absorber 13, the entire absorbent body 10 is folded in half along the through hole 7, and the top surface attached to the absorbent body 10 can be attached. The fold on 1 is limited to a minimum. That is, as described above, the top surface portion 1 preferably has a flat surface and does not have any wrinkles, but forms a fold which must be generated at the time of manufacture along the through hole 7, and the wrinkle attached to the top surface portion 1 can be minimized. Thereby, it is also possible to form a state in which the fold hardly remains on the top surface portion 1 at the time of wearing.

[14. Eleventh embodiment]

Next, an eleventh embodiment of the absorbent article 100 of the present invention will be described with reference to Figs. 45 to 48. The eleventh embodiment is the same as the above-described tenth embodiment, and the description thereof is omitted, and the structure different from the tenth embodiment will be mainly described.

Fig. 45 is an exploded perspective view showing the absorbent article 100 according to the eleventh embodiment, and Fig. 46 is a cross-sectional view showing the absorbent article 100 according to the eleventh embodiment. As shown in Fig. 45 and Fig. 46, the absorbent article 100 according to the eleventh embodiment further includes two sub absorbers 14 in addition to the constituent elements described in the tenth embodiment.

As shown in Fig. 46, in the present embodiment, the sub-absorbent body 14 is disposed one on each of the left and right side surface portions 2, 3 of the absorbent main body 10. In particular, the two sub-absorbers 14 are disposed on the skin non-opposing surface side of the main absorbent body 13 constituting the top surface portion 1 and the left and right side surface portions 2, 3, that is, between the main absorbent body 13 and the inner surface sheet 12. Further, similarly, each of the sub-absorbers 14 and the main absorber 13 may be composed of an absorbent material 14a and a core-coated sheet 14b. In the present embodiment, the amount of absorption of the body fluid in the side portions 2, 3 is increased by superposing the main absorbent body 13 and the sub-absorbent body 14 on the left and right side surface portions 2, 3. In particular, the body fluid introduced into the space 4 through the through hole 7 of the top surface portion 1 can be absorbed in a large amount by the sub-absorber 14 disposed on each of the side surface portions 2 and 3. Therefore, this embodiment can be said to be a form suitable for a male who uses a penis inserted into the through hole 7 of the top surface portion 1. Further, as shown in Fig. 46, it is preferable that the sub-absorbent body 14 is disposed so as to overlap the main absorber 13 at least on the lower end portion 5 side of the left and right side surface portions 2, 3. However, the sub-absorber 14 may be disposed to overlap the main absorber 13 over the entire left and right side portions 2 and 3. Further, although not shown in the drawings, the sub-absorbent body 14 may be disposed on the skin facing surface side of the main absorbent body 13, that is, between the main absorbent body 13 and the outer sheet 11.

As shown in Fig. 45 and Fig. 46, in the eleventh embodiment, a plurality of strips are formed on each of the absorbers of the main absorber 13 and the sub-absorber 14, so that the absorbers 13 and 14 are recessed in the thickness direction. The lines 41, 51 are extruded. That is, the plurality of extrusion lines 41 and 51 are formed on the respective absorbers of the main absorbent body 13 and the sub-absorbent body 14. Extrusion lines 41, 51 are by Each of the extrusion lines 41, 51 is partially compressed and compressed from the opposite side or the side of the skin non-opposite side of the skin. Therefore, the density of the absorbent materials 13a and 14a of the respective absorbers 13 and 14 is increased at the portions where the extrusion lines 41 and 51 are formed. Further, the extrusion line 41 formed on the main absorbent body 13 and the extrusion line 51 formed on the sub-absorber 14 form a pattern that at least partially intersects each other when viewed in the planar direction. Hereinafter, the pattern of the extrusion line 41 formed on the main absorber 13 and the pattern of the extrusion line 51 formed on the sub-absorber 14 will be described in detail.

Fig. 47 is a view showing a state in which the patterns of the extrusion lines 41, 51 formed on the main absorbent body 13 and the sub-absorbent body 14 are superposed. As shown in Fig. 45 or Fig. 47, the main absorbent body 13 is formed with a pressing line 41 in a diagonal square lattice pattern. Here, the "skewed square lattice pattern" refers to a pattern in which a plurality of extrusion lines extending in a direction inclined in the longitudinal direction and the width direction intersect with each other and a rhombic (diamond) non-extrusion region is divided. For example, as shown in Fig. 47, the angle (θ) at which the extrusion line is inclined with respect to the width direction of the absorbent article can be set to a range of 1 to 45 degrees, and further preferably 30 to 45 degrees or 35 to 45 degrees. . In particular, in the present embodiment, the pattern of the extrusion line 41 on the main absorbent body 13 is formed such that the non-extrusion regions 42 surrounded by the extrusion line 41 all have a regular pattern of a rhombic shape (a rhomboid). A diagonal square lattice pattern). As such, the main absorber 13 can be imagined as a plurality of extrusion lines 41, a non-extrusion region 42 surrounded by the extrusion line 41, and an intersection portion 43 where the extrusion line 41 intersects. Hereinafter, for the sake of convenience, the extrusion line 41 of the main absorbent body 13 is referred to as "upper extrusion line 41", the non-extrusion region 42 is referred to as "upper non-extrusion region 42", and the intersection portion 43 is referred to as "upper intersection" Part 43".

On the other hand, the sub-absorbent body 14 is formed with a squeeze line 51 in a square lattice pattern. The "square lattice pattern" as used herein refers to a plurality of extrusion lines and width directions extending in parallel with the longitudinal direction. A plurality of extruded lines extending in parallel intersect and are divided into a pattern of non-extrusion regions of a quadrangular shape. In particular, in the present embodiment, the pattern of the extrusion line 51 on the sub-absorber 14 is formed such that all of the non-extrusion regions 52 surrounded by the extrusion line 51 have a square regular pattern (a square lattice pattern). . As described above, in the sub-absorbent body 14, it is also conceivable that a plurality of extrusion lines 51 are formed, and the non-extrusion region 52 surrounded by the extrusion line 51 and the intersection portion 53 where the extrusion line 51 intersects. Hereinafter, for the sake of convenience, the extrusion line 51 of the sub-absorber 14 is referred to as "lower extrusion line 51", and the non-extrusion area 52 is referred to as "lower non-extrusion area 52", and the intersection portion 53 is referred to as " Lower intersection point 53".

Further, in the present embodiment, the upper pressing line 41 is formed by being recessed by compressing the main absorbent body 13 from the skin facing surface side. Similarly, the lower pressing line 51 is formed by compressing the sub-absorbent body 14 from the skin facing surface side. Therefore, the portion where the lower extrusion line 51 is formed on the sub-absorber 14 is in a state in which the main absorber 13 and the sub-absorber 14 are superposed, and a gap is formed therebetween.

As is apparent from Fig. 47, in the present embodiment, the area of the lower non-extrusion region 52 is larger than the area of the upper non-extrusion region 42. Therefore, when the main absorber 13 and the sub absorber 14 are overlapped, the upper non-extrusion area 42 (orthogonal square) is accommodated in the range of the lower non-extrusion area 52 (square).

Further, in the present embodiment, the four upper side intersection portions 43 defining a certain upper non-extrusion region 42 (forward rhombic) are respectively pressed to the lower side of the four sides defining the lower non-extrusion region 52 (square). The press lines 51 overlap. Therefore, as shown in Fig. 47, it is found that the upper non-extrusion region 42 (orthogonal square) is just accommodated in the range of the lower non-extrusion region 52 (square). That is, the center of the lower non-extrusion region 52 (square) (the intersection of the diagonal lines) coincides with the center of the upper non-extrusion region 42 (the oblique square) (the intersection of the diagonal lines). Furthermore, as shown in Fig. 47, the lower non-extrusion area 52 (square The length L of the longitudinal direction of the shape is slightly equal to the length D1 of the diagonal along the longitudinal direction of the upper non-extrusion region 42 (orthogonal square) (L=D1). Further, the length B of the lower non-extrusion region 52 (square) in the width direction and the length D2 of the diagonal along the width direction of the upper non-extrusion region 42 are slightly equal (B=D2). When these conditions are satisfied, the four upper side intersection portions 43 defining the upper non-extrusion region 42 (forward rhombic square) become the lower side extrusion line 51 which respectively defines the four sides of the lower side non-extrusion region 52 (square). overlapping. Furthermore, the term "slightly" in the specification of the present specification means an error of ±5%.

As described above, by forming the pattern of the upper side extrusion line 41 (the diagonal square lattice shape) and the pattern of the lower side extrusion line 51 (square lattice shape), even if the extrusion line is not densely formed on one of the absorbers, The body fluid can be effectively diffused into the non-extrusion region, and the body fluid can be absorbed over a wide range of the entire absorbent body of the two layers. That is, the body fluid diffused along the upper extrusion line 41 of the main absorbent body 13 is absorbed by the lower non-extrusion region 52 of the sub-absorbent body 14. Therefore, the body fluid diffused along the upper side extrusion line 41 of the main absorbent body 13 does not reach the end portion, and the leakage to the outside can be effectively prevented. Further, since the body fluid can be absorbed in a wide range of the two layers of the absorbent bodies 13, 14, the amount of absorption of the body fluid is improved, and the wearer is not unpleasant even if worn for a long period of time. In the intersection portions 43 and 53 formed on the respective absorbers 13 and 14, since the extrusion lines 41 and 51 intersect, the body fluid tends to stay. By overlapping the upper intersection portion 43 of the main absorber 13 with the lower extrusion line 51 of the sub-absorber 14, the body fluid retained in the upper intersection portion 43 can be introduced into the lower extrusion line 51 and made effective. The ground penetrates into the secondary absorber 14.

Fig. 48 is a view showing a variation of the pattern of the extrusion line 41 formed on the main absorbent body 13 and the pattern of the extrusion line 51 formed on the sub-absorber 14. In the modification shown in FIG. 48, in the state in which the respective absorbers 13 and 14 are overlapped, the upper intersection portion 43 of the main absorber 13 overlaps with the lower intersection portion 53 of the sub absorber 14. Furthermore, a plurality of the main absorbers 13 A portion overlapping the center (the intersection of the diagonal lines) of the lower non-extrusion region 52 of the sub-absorber 14 exists in the upper intersection portion 43. In particular, in a range in which the pattern of the upper side extrusion line 41 of the main absorbent body 13 overlaps with the pattern of the lower side extrusion line 51 of the sub-absorber 14, the upper side intersection portion 43 exists in all of the lower non-extrusion areas 52. Within the scope. Further, in the present embodiment, the lower pressing line 51 is overlapped in the range of the upper non-extrusion region 42.

As described above, in the modification shown in FIG. 48, the lower side extrusion line 51 is overlapped in the range of the upper non-extrusion area 42, and the upper side extrusion line 41 and the upper side intersection part 43 are overlapped in the lower side non-extrusion area 52. Within the range, the upper intersection portion 43 and the lower intersection portion 53 overlap. Therefore, the body fluid diffused along the upper side extrusion line 41 of the main absorbent body 13 falls onto the sub-absorbent body 14 and is absorbed by the lower non-extrusion region 52. Further, the body fluid remaining in the upper intersection portion 43 of the main absorbent body 13 falls on the sub-absorbent body 14 and is diffused along the lower extrusion line 51 by the lower intersection portion 53. Further, the body fluid diffused along the lower side extrusion line 51 of the sub-absorber 14 is absorbed by the upper non-extrusion region 42 of the main absorber 13. Further, the lower side extrusion line 51 may also diffuse the body fluid in the diagonal direction of the lattice pattern of the upper side extrusion line 41. Thereby, by forming such a pattern, the body fluid can be quickly guided by the non-extrusion regions 42, 52 which have been conventionally regarded as having a slow absorption time.

Thus, the pattern shown in Fig. 48 can be said that the absorption rate of the body fluid is faster than that of the pattern shown in Fig. 47. In contrast, the pattern of Fig. 47 can be said that the diffusion range of the body fluid is wider than that of the pattern of Fig. 48. Therefore, in the case where the extrusion line is formed on each of the absorbers of the two-layered absorbent body, any one of the patterns of Figs. 47 and 48 can be appropriately determined in consideration of the performance required for the absorbent article.
