  Although the embodiments include various variations, the reference numerals given to the components of the embodiments shown in the drawings are in principle the case where they are substantially the same as the components of the invention regardless of the variations. The same reference numerals are attached, and the explanation of the configuration, action, effect, and the like described above is incorporated, and various aspects of the invention are explained in a unified manner while avoiding the trouble due to the distinction of reference signs. Moreover, although the manufacturing method of each absorber product and the structure obtained by the said manufacturing method were classified and described for every embodiment, the structure described in each embodiment is another embodiment equivalent to the said structure. It can be arbitrarily replaced with the configuration of and combined.

1. 1st Embodiment (FIGS. 1-17): Straight cut system (1) Manufacturing method The absorber product 1a of this example is a tapeless type (pants type) diaper provided with a structure different from the conventional one. It is manufactured according to the following process described separately.

  As shown in FIG. 1, in this step, a strip-shaped nonwoven fabric 2 (PP spun melt nonwoven fabric or the like) continuous in a predetermined direction and a liquid-impermeable sheet 3 (in a strip shape continuous in a predetermined direction and smaller in width than the nonwoven fabric 2) Use a breathable film. The predetermined direction is a horizontal direction in an actual manufacturing process, but is represented as a vertical direction in the figure. That is, while the non-woven fabric 2 is continuously supplied and conveyed in a predetermined direction, the liquid impermeability is smaller in width than the non-woven fabric 2 in the center of the non-woven fabric 2 in the width direction (left and right direction in the figure orthogonal to the predetermined direction) at a predetermined position. The sheet 3 is supplied, overlapped, and continuously joined to form a strip-shaped leak preventer continuous in a predetermined direction.

  The joining is performed using a hot melt resin or the like. The same applies to the other steps and the bonding performed in the steps described in the second embodiment and thereafter.

  In this example, both the non-woven fabric 2 and the liquid impermeable sheet 3 are expressed in a strip shape in which the dimension in a predetermined direction is limited in the figure, but in actuality, it is a long strip material in the predetermined direction. The material supply location of the process is stored in, for example, a roll shape, and is configured so that the material is fed out in a predetermined direction and conveyed in a predetermined direction according to the progress of the process. In addition, in this example and description after 2nd Embodiment, the structural member used by a manufacturing process is continuous in a predetermined direction like the said nonwoven fabric 2 and the said liquid impervious sheet 3 unless there is particular notice. It is assumed that the material is a long belt-like material.

  As shown in FIG. 2, a plurality of absorbent bodies 4 having a width smaller than that of the liquid impermeable sheet 3 are arranged on the central portion in the width direction of the liquid impermeable sheet 3 at appropriate intervals in a predetermined direction. I will do it. The type of the absorbent body 4 is not particularly limited, but if a component other than the liquid absorbent material itself, for example, a top sheet or AQL (Aquisition Layer) to be placed on the liquid absorbent material is necessary, these are combined in advance. Although not shown, these components are stacked on the absorbent body 4 during the process, but this corresponds to the function / structure of the absorbent body 4 required by the specifications of the absorbent product 1a. .

  As shown in FIG. 3, two boundary portions related to the width direction of the nonwoven fabric 2 and the liquid impermeable sheet 3 that are stacked, that is, continuous in a predetermined direction in which the nonwoven fabric 2 and the liquid impermeable sheet 3 are adjacent to each other in the width direction. A plurality of elastic members 5 are respectively arranged in two regions that are stretched in a predetermined direction. A polyurethane filament or the like can be used as the elastic member 5. In addition, since the leg hole 6 is formed in the boundary portion between the nonwoven fabric 2 and the liquid impermeable sheet 3 in a later step, there is provided a room for forming the leg hole 6 without cutting the elastic member 5, and the leg hole 6 A portion having a relatively wide interval a is provided in the interval between the elastic members 5 so that the elastic members 5 are disposed on both sides of the elastic member 5. Here, the distance a is between the elastic member 5 provided on the nonwoven fabric 2 and the elastic member 5 provided on the liquid-impermeable sheet 3.

  As shown in FIG. 4, both side edges in the width direction of the nonwoven fabric 2 are folded inward, and the elastic member 5 is sandwiched between them.

  As shown in FIG. 5, in the two boundary regions on both sides of the absorber 4, the leg hole 6 is formed as a slit-shaped opening along a predetermined direction at a position where the distance between the elastic members 5 is a wide. Form through. As a result, the elastic member 5 is arranged above and below the leg hole 6 (left and right in the figure), and when worn, the entire circumference of the leg hole 6 is elastically adhered to the circumference of the wearer's leg. Can be kept sealed.

  As shown in FIG. 6, the absorbent body 4 is folded in half along the center line parallel to the predetermined direction through the center in the width direction of the absorbent body 4 so that both side edges in the width direction of the nonwoven fabric 2 overlap. Wrap the whole thing.

  As shown by a chain line in FIG. 7A, the absorbent product 1a as shown in FIG. 7B is cut by sealing between the absorber 4 and the absorber 4 along a direction orthogonal to the predetermined direction. Separated. In addition, the shape of the absorbent product 1a shown in FIG. 7 (b) represents individual products at the moment when the seal is cut while being stretched by applying tension in a predetermined direction as shown in FIG. 7 (a). Actually, at the moment when the seal is cut and separated into individual products, the elastic member 5 is retracted, so that the portion above the leg hole 6 as shown in FIG. Shrinks, and a portion (bag portion 8 to be described later) below the leg hole 6 is relatively extended in the front-rear direction.

  Thus, according to the manufacturing method of the absorbent product 1a of this example, the belt-shaped nonwoven fabric 2 and the liquid impermeable sheet 3 are stacked and conveyed in the horizontal direction, and the absorbent bodies 4 are arranged at predetermined intervals thereon. Then, the elastic member 5 extended in the carrying direction is arranged, and the whole is folded in half along the center line parallel to the carrying direction, and the individual absorbent bodies are cut and sealed one after another. Since it can isolate | separate into the product 1a, the absorber product 1a can be mass-produced easily and reliably.

  In addition, in the manufacturing method of this example, as shown to Fig.5 (a), although the left and right legholes 6 and 6 were each formed separately, after the whole was turned in the process shown in FIG. The left and right leg holes 6 and 6 may be collectively formed by cutting through.

(2) Structure (FIGS. 8 to 11)
Next, the structure of the absorbent product 1a obtained by the above steps will be described with reference to FIGS. FIG. 8 thru | or FIG. 9 has shown the form at the time of extending the absorber product 1a of this example so that it might mount | wear with a human body. First, the body portion 7 is a circumferential portion composed of the nonwoven fabric 2 with the elastic member 5 interposed therebetween, and is provided with a waist hole 9 penetrating vertically, and is attached elastically to the wearer's waist. Is done.

  The bag portion 8 integrally formed on the lower side of the body portion 7 is housed inside the bag body 11, a bag body 11 communicating with the opening on the lower side of the waist hole 9 of the body portion 7 through the upper opening 10. Consisting of the absorbent body 4. The bag body 11 is composed of a leak-proof body composed of the outer nonwoven fabric 2 and the inner liquid impermeable sheet 3, and the absorbent body 4 is disposed along the inner surface of the bag body 11 at the bottom of the bag body 11. . A leg hole portion in which the leg hole 6 is opened is formed at each boundary portion between both side surfaces of the body portion 7 and the bag portion 8.

  Therefore, the trunk | drum 7 and the bag part 8 are the rear part corresponding to the wearer's abdomen and the front center corresponding to a wearer's back | dorsal part except the bottom part of the bag part 8 turned back by the centerline along a wearer's front-back direction. The center is joined to each other.

  When wearing the absorbent body product 1a having such a structure, the wearer puts both legs into the body part 7 from the waist hole 9, and then protrudes from the inside of the leg hole 6 to the outside, lifting the body part 7 and lifting the waist part. Attach around.

  In such a wearing state, the bag portion 8 in which the absorbent body 4 is housed is suspended from the body portion 7 between the wearer's legs, and reaches the rear lower back portion from the wearer's front lower abdomen through the crotch portion. A part involved in excretion of urine and feces is in a state of facing the upper opening 10 of the bag body 11. That is, the ejector and the position where the absorber exists are in a separated state. Most of the urine and feces excreted from the wearer can enter the bag portion 8 from the upper opening 10 without contacting the body surface of the wearer.

  According to the conventional absorbent product, the absorber is placed in close contact with the body surface, and the method of closely adsorbing urine flowing between the body surface and the absorbent with the absorber has been adopted. The entire amount is difficult to use efficiently, the skin may be irritated, and the feeling of wearing is not good, but according to the absorbent product 1a of this example, the urine and feces excreted by the wearer are Since it does not come into contact with the body surface and enters the bag portion 8 from the upper opening 10, urine or the like easily moves inside the bag body 11 and is efficiently absorbed by the internal absorber 4. Is placed in the bag 11 and is always away from the body surface of the wearer, so that urine does not stay between the absorbent body 4 and the skin, and there is little possibility that the skin will be covered with urine. Moreover, a feeling of wear is also favorable.

  Moreover, since the elastic member 5 exists under the trunk | drum 7 and the leg hole 6, high adhesiveness is obtained in the part which contacts a human body, and a liquid leak and an odor leak are prevented.

  Moreover, as shown in FIG.7 (b), since the leg hole 6 of this example is formed in the abdomen a little rather than the center of the junction part of a back part, and the junction part of an abdomen, the volume which accommodates a stool is large. Moreover, if the leg hole 6 is formed in the center of the junction part of a back part and the junction part of an abdomen and the thing of the front and back is the same shape, there will be no distinction of front and back, and it can wear without confirming front and back. Further, if the leg hole 6 is inclined with respect to the upper edge of the body part 7 so as to rise from the back part toward the abdomen, the abdomen side of the bag part 8 is lowered in the worn state, and urine is in front of the bag part 8. If the leg hole 6 is formed so as to be inclined downward from the back toward the abdomen, the back side of the bag 8 is lowered when worn, and urine is guided to the rear of the bag 8. Since it becomes easy, it is possible to easily set urine in an appropriate part of the bag body 11 according to the expected posture of the wearer.

  In addition, as shown in FIG. 7B, the leg hole 6 of this example is formed as a slit-like opening (linear opening), but the opening shape is a horizontally long rectangle or an ellipse or other horizontally long shape. You may form as a notch-shaped opening whose opening area is larger than a slit. Thus, a notch-shaped opening having a large opening area facilitates the wearing operation because it is easy to pass the wearer's leg when wearing, but the airtightness is lowered.

  FIG. 10 is a perspective view showing the absorbent product of the present example described above in an expanded state, and FIG. 11 (a) is a perspective view partially showing a state in which an infant wears the absorbent product of the present example. The front view and the figure (b) which are shown in this figure are the side views.

A space having a height L is formed between the lower end of the sheet-like absorbent body 4 and the bottom of the bag body 11, and a gap 12 that connects the space above the sheet-like absorbent body 4 and the space is formed in the sheet-like absorbent body 4. Is formed at the lower end. Such a space plays a very important role for an absorber composed mainly of SAP. That is, since it takes a set time to start the swelling absorption of SAP, a function of temporarily storing urine is required. The present inventors refer to this as a trap function, but this space is for exhibiting such a function. Note that the height L of the space between the lower end of the sheet-like absorbent body 4 and the bottom of the bag body 11 more effectively achieves the trap function in the same space, as well as the purpose of moving urine and storing stool. For this purpose, for example, it is preferably 5 mm or more. More preferably, it is 10 mm-30 mm.

  According to the modification of FIG. 12A, two sheet-like absorbers 4 having different left and right dimensions are extended obliquely downward, and both lower end portions are overlapped with a gap 12 therebetween. According to the modified example of FIG. 12B, the two sheet-like absorbers 4 having the same horizontal dimension are extended obliquely downward so that both lower end portions face each other with a gap 12 therebetween.

  As shown in FIG. 49, the non-woven fabric 2 is cut along a predetermined direction between the two parts and divided into two to form a band-shaped member (part which becomes the body part 7 when completed) continuous in two predetermined directions. .

  As shown in FIG. 50, both side edges in the width direction of the absorbent body 4 are folded inward to form the flanges 16.

  As shown in FIG. 51, the absorbent body 4 is formed by cutting in a direction perpendicular to a predetermined direction along a cutting line indicated by a chain line, and appropriately setting the dimension in the predetermined direction.

  As shown in FIG. 52, a liquid impermeable sheet 3 having a band shape continuous in a predetermined direction and having a width smaller than that of the nonwoven fabric 2 is overlapped at the center in the width direction of the belt-shaped nonwoven fabric 2 continuous in a predetermined direction. In the center in the width direction of the sheet 3, a plurality of absorbent bodies 4 having a width smaller than that of the liquid-impermeable sheet 3 are arranged at appropriate intervals in a predetermined direction, and these are bonded and integrated.

  As shown in FIG. 53, a plurality of elastic members 5 extended in a predetermined direction are arranged on both side edges in the width direction of the liquid-impermeable sheet 3, respectively.

  As shown in FIG. 54, both side edges in the width direction of the nonwoven fabric 2 are folded inward and bonded with the elastic member 5 interposed therebetween, thereby forming a bag portion 8 having a stretchable band 20 for preventing liquid backflow when completed. Forming part.

  As described above, the portion to be the body portion 7 manufactured in the separate process and the portion to be the bag portion 8 manufactured in the separate step as described above are combined. First, as shown in FIG. 55, the portions that become the two body portions 7 are arranged along the predetermined direction at intervals in the width direction, and between the portions (7) and (7) that become the two body portions 7 In addition, the portion (8) that becomes the bag portion 8 with the stretchable band 20 is stacked and placed in a stretched state along a predetermined direction.

  As shown in FIG. 57, the overlapping portion of the portion (7) that becomes the body portion 7 and the portion (8) that becomes the bag portion 8 with the elastic band 20 is a leg hole 6 in which the portion close to the absorber 4 is unjoined. The crank-shaped seal portion 25 is formed at intervals in a predetermined direction so as to be configured. To describe the shape of the seal portion 25 in detail, the first seal portion 25a along the predetermined direction from the both side edges of the one end portion of the absorber 4 with respect to the predetermined direction to the region between the adjacent absorbers 4, A second seal portion 25b that extends from the first seal portion 25a to the portion (20) that becomes the stretchable band 20 along the width direction orthogonal to the first seal portion 25a, and continues to the second seal portion 25b. And a third seal portion 25c along a predetermined direction that continues to a position corresponding to the midway portion of the adjacent absorber 4 along the portion (20), and each seal portion 25a, 25b, 25c is continuous. As a whole, the shape is such that two L-shapes having substantially the same shape are combined with the object to be rotated.

  Then, along the center line passing through the center of the absorbent body 4 in the width direction and parallel to the predetermined direction, the absorbent body 4 is folded in two and the whole body portion 7 is folded back so that both side edges in the width direction overlap.

  As shown by a chain line in FIG. 58 (a), by passing through the second seal portion 25b between the absorber 4 and the absorber 4 along a direction orthogonal to the predetermined direction, and performing a seal cut, FIG. The absorbent product 1d as shown in FIG. The shape of the absorbent product 1d shown in FIG. 58 (b) represents an individual product at the moment when the seal is cut while being stretched by applying tension in a predetermined direction as shown in FIG. 58 (a). In fact, at the moment when the seal is cut and separated into individual products, the upper body portion 7 is contracted as shown in FIG. The upper part of the bag part 8 shrinks, and it becomes the external shape where the lower part overhangs back and forth.

  According to the manufacturing method of the absorbent product 1d of this example, the elastic member 5 is sandwiched between the nonwoven fabrics 2 and includes a portion that becomes the body portion 7 that is long in a predetermined direction, the nonwoven fabric 2, the liquid-impermeable sheet 3, and the absorber 4. Each of the portions that become the long bag portion 8 in the predetermined direction having the elastic band 20 for preventing the liquid back flow is manufactured in advance. And the part which becomes the bag part 8 is mounted on the part which becomes the two trunk | drums 7 with the space | interval, and the leg hole 6 is formed by sealing in a substantially crank shape in the overlapping part. Then, the whole is folded in half along a center line parallel to a predetermined direction, and a seal is cut through a seal portion between the absorber 4 and the absorber 4 along a direction orthogonal to the predetermined direction. Separated into product 1d. According to this example, by such a continuous and simple manufacturing method, it is possible to easily and reliably produce the absorbent product 1d in a form in which the bag portion 8 with the stretchable band is opened wider at the rear than the front of the wearer. The effect of mass production is obtained.

(2) Structure (FIGS. 59 to 65)
Next, the structure of the absorbent product 1d obtained by the above steps will be described with reference to FIGS. 59 (a) and 59 (b) and FIGS. These figures show the form when the absorbent product 1d of the present example is spread as if it is worn on a human body.

  The absorbent product 1d of the present example has the same basic structure as the absorbent product 1a of the first embodiment described with reference to FIGS. 7C to 7E, but FIG. 59A and FIG. 61, 63, and 64, the elastic band 20 provided so as to project inward from the upper edge of the bag portion protrudes from both sides in front of the bag portion 8 and has a narrow width. . And since it is not adhere | attached on the trunk | drum 7, it is not influenced by the expansion-contraction of a trunk | drum. The upper opening 10 of the bag portion 8 containing the absorbent body 4 becomes narrower toward the front side of the wearer and is closed to form a urine pocket. On the other hand, as shown in FIG. 59 (a), FIG. 62, and FIG. 65, the elastic band 20 behind the bag portion 8 is bonded to the body portion 7 on the outer side. The upper opening 10 of the portion 8 is wide open on the rear side of the wearer, and a stool passing space is secured.

  For this reason, according to the absorbent product 1d of this example, urine discharged to the front (abdominal side) of the wearer leaks from the front portion of the bag portion 8 in which the upper opening 10 is narrow and the elastic band 20 is provided. The stool that is difficult to be discharged to the back (back side) of the wearer is stored in the back portion of the bag portion 8 having a wide upper opening 10.

  In addition, the upper edge of the leg hole 6 has an elastic member 5 of the body part 7, and the lower edge has an elastic member 5 of an elastic band 20 of the bag part 8, and the circumferential surface of the wearer's leg and the leg hole 6 High adhesion is obtained between the periphery and liquid leakage and odor leakage are prevented.

  As described above, in any of the embodiments of the present invention, the bag portion 8 having the absorber 4 is disposed between both legs with the upper opening 10 facing the lower half of the wearer's legs. Since the urine discharged by the wearer is discharged into the bag portion 8, the possibility of the urine etc. adhering to the skin is low, so that the skin is hardly irritated and the wearing feeling is good. Moreover, when the urine moves inside the bag 11, the internal absorber 4 can be used efficiently. In contrast, conventional absorbent products are arranged with the absorbent body in close contact with the skin, and the body fluid (urine) that spreads between the skin and the absorbent body is absorbed only by the absorbent body that is in close contact with the skin. However, the absorbent product 1d of this example is an epoch-making absorbent product 1d that adopts a completely different structure and absorption mechanism.

  In any of the embodiments of the present invention, the continuous band-shaped material is transported in a predetermined direction while being overlapped or folded, and finally the seal is cut and separated into individual absorber products to be completed. By the continuous and simple production method, the effect that the absorbent product of the present example having the above-described innovative absorption mechanism can be easily and reliably mass-produced is obtained.
