A liquid-impermeable sheet material 2 is applied to the outer surface of the urging 1, and an absorbent body for absorbing liquid such as urine is disposed on the inner side of the sheet material 2. A sheet material 3 that is permeable to liquid is disposed at a location where it contacts with.
[0003]
In general, the squeeze 1 is provided with sealing means 4 made of gathers or the like so as to surround the user's crotch when worn by the user. This sealing means 4 prevents liquid such as urine from flowing to the outside of the urine 1 to contaminate underwear or the like.
[0004]
[Problems to be solved by the invention]
By the way, such an urine 1 may excrete a large amount of liquid such as urine in a short time while being worn and used. In this case, the excreted urine is concentrated and hits a certain part of the surface of the liquid-permeable sheet material 3 that is in contact with the user's skin.
[0005]
Under the liquid-permeable sheet material 3, an absorber is disposed as described above so as to absorb the urine and the like. Actually, however, a large amount of urine excreted in an instant is predetermined. In order to concentrate on the location, the absorber cannot absorb urine or the like in this short time, spreads on the surface of the sheet material 3, reaches the end in the length direction of the sheet material 3, and is absorbed by the absorber below it Before being done, it may leak from the lateral crotch.
[0006]
In particular, if the user urinates with the urine 1 attached, a large amount of urine may move in the back direction (the length direction of the urine 1) at a time and leak from the end in the length direction. is there.
In any of the above-described cases, the absorber below the end of the sheet material 3 corresponding to the corner of the squeeze 1 cannot absorb liquid such as urine. In FIG. There existed a problem that the absorber arrange | positioned in the area | region which shows was not functioning.
[0007]
The present invention has been made in order to solve such problems. By promptly guiding the liquid discharged by the wearer toward the end portion of the sheet material, the absorbent body functions in a wide range. It is an object of the present invention to provide an absorptive product that can be completely sealed inside without leaking liquid such as the like.

The first sheet material 11 does not allow liquid to pass through, but preferably allows the water vapor to permeate to prevent stuffiness, and a material having some flexibility is selected. (Dirt) does not leak to the outside. For this reason, as the material of the first sheet material 11, a thin plastic film, specifically, a polyethylene film or polyethylene laminated paper is selected.
[0040]
Since the second sheet material 12 directly touches the user's skin, a material suitable for the second sheet material 12 is selected in consideration of a good touch without damaging the skin more than necessary. Furthermore, the second sheet material 12 is appropriately selected from various natural fibers, synthetic fibers, or a combination thereof as a fiber of a material suitable for allowing liquid to permeate and liquid components to permeate quickly. The
As the synthetic fiber, for example, a fiber made of polyester or polypropylene fiber so as to improve liquid permeability is suitable.
[0041]
The first sheet material 11 and the second sheet material have a size and a shape suitable for use as a squeeze, for example, as shown in the figure, and are fixed in an overlapping manner. This fixing method is suitably fixed by bonding or sewing, for example, at the whole or a part of the peripheral portion or at a location inside thereof.
The 1st sheet material 11 and the 2nd sheet material 12 which were piled up mutually are made into a shape like FIG. 2, for example, when comprising an urine as an absorptive product.
[0042]
In FIG. 2, the squeeze 10 has a substantially rectangular shape as a whole, and the edge portions 17 and 18 that constitute each long side and face each other are not illustrated, but are concave inwardly in the vicinity of the center thereof. A crotch portion may be provided.
Oshime 10 has three regions that are substantially divided in the vertical direction (vertical direction in the figure), and in the figure, the first region 21, the second region 22, and the third region from the top. 23. The first area 21 corresponds to the area corresponding to the rear side of the lower back from the hip when the user wears the urine 10, and the second area 22 includes the crotch portion including the perineum of the user. The third area 23 corresponds to the area on the front side of the lower back of the user.
[0043]
As shown in FIG. 3, an absorber 16 is disposed between the first sheet material 11 and the second sheet material 12. The absorber 16 serves to absorb and retain the liquid component that has permeated and penetrated the second sheet material 12. Accordingly, a material having excellent liquid absorbability is used.
As such a material, for example, a pulp absorber formed by mixing a polymer as an absorbent material with pulp as an absorber, or by dispersing a polymer on pulp, or a polymer described later is preferable.
Here, the pulp is, for example, an aggregate of cellulose fibers extracted by mechanically or chemically treating wood, and a linear or sheet-like product is used. As the polymer as the absorbent material, for example, a water-absorbing polymer is suitable. For example, a polyacrylate copolymer, a hydrolyzate of starch-acrylonitrile graft copolymer, starch-acrylic acid graft copolymer, polyvinyl Alcohol-acrylate copolymer, modified carboxymethyl cellulose and the like can be mentioned.
Furthermore, the absorbent 16 can contain a bactericidal agent, thereby preventing bacteria from generating ammonia from urea in the urine. As a result, it is possible to effectively prevent the occurrence of rough skin. Examples of such bactericides include benzalkonium chloride and chlorhexidine gluconate.
[0044]
In this embodiment, the absorber 16 is divided into a first absorber 16a and a second absorber 16b and is accommodated in an overlapping manner.
That is, as shown in FIG. 3 and FIG. 4, a tissue 21 is disposed under the second sheet material 12, and a first absorbent body 16 a is disposed under the tissue 21. A second absorber 16b wrapped with a tissue 22 is disposed under the absorber 16a.
[0045]
Further, the urging 10 is formed with a first flap portion 13 and a second flap portion 14.
As shown in FIG. 2, the first and second flap portions are provided along the side edge portions 17 and 18 of the urging member 10 that face each other. Here, “outer side” refers to the virtual line CL in FIG. 2 as a reference, with respect to the virtual line CL, a direction closer to CL is defined as “inside”, and a direction away from this is defined as “outside”.
[0046]
As shown in FIG. 2, the first flap portion 13 is formed so as to extend in the longitudinal direction with a certain width at each side edge of the fold 10.
As shown in FIGS. 3 and 4, the first flap portion 13 forms a portion obtained by extending the side edge portion of the first sheet material 11 outward and a second flap portion described later. The side edges of the material are overlapped to form a band.
[0047]
The first flap portion 13 is formed of a material having a certain degree of rigidity and flexibility. For example, a combination of a polyolefin-based nonwoven fabric or a polyester-based nonwoven fabric and a thin plastic film, a combination of a polyester-based nonwoven fabric and a polyethylene film, etc. Is suitable.
For this reason, the first flap portion 13 follows the curved shape on the inner peripheral side of both thick crotch portions in the vicinity of the crotch portion and surrounds the thick crotch portion when the user wears the urinal 10. The shape is held so that it can be brought into contact with and closely attached.
Thereby, the 1st flap part 13 plays the role which seals the excrement of the user mentioned later in the thigh vicinity of the crotch vicinity.
[0048]
As shown in FIGS. 3 and 4, the second flap portion 14 is arranged adjacent to the first flap portion 13 and on the inner side (the imaginary line CL side in FIG. 2). .
This 2nd flap part 14 is formed with the strip | belt-shaped member 15 extended in a longitudinal direction, as FIG. 2 shows.
That is, as shown in FIGS. 3 and 4, the inner side surface 14 a of the band-shaped member 15 is folded at the front end side, and, for example, a rubber-like long elastic material 17 is inserted along the longitudinal direction. . The middle portion of the belt-like member 15 is fixed to the side edge portion of the second sheet material 12.
[0049]
On the other hand, the outer edge portion of the belt-like member 15 is overlapped and fixed on the side edge portion of the first sheet material 11 to form the first flap 13 as described above. A long rubber-like elastic material 19 is also inserted and fixed along the longitudinal direction at the end of the first flap 13.
Thereby, the 1st flap 13 functions as a crotch gather closely_contact | adhering to a user's crotch part.
[0050]
Here, like the first flap 13, the belt-like member 15 constituting the second flap portion 14 is suitable for a waterproof property having a certain rigidity and flexibility. For example, polyester It is made of a non-woven fabric of polyolefin or polyolefin.
Thereby, this 2nd flap part 14 acts so that a user's excrement or its liquid component may block inside the 1st flap 13 so that it may not leak outside.
In particular, the second flap portion 14 has its end portion 14a standing up and in close contact with the user's skin as shown in FIG. 3 near the second region 22 by the action of the elastic material 17. By acting on, the sealing performance of liquid or the like is improved.
[0051]
Further, in the present embodiment, as shown in FIG. 2, an initial absorption portion 35 is provided on the surface of the second sheet material 12 (the side in contact with the user's skin). In the example of FIG. 2, the initial absorption portion 35 is provided in the vicinity of the approximate center of the urination 10, but this position is not necessarily appropriate, and the position where the initial absorption portion 35 is provided will be described later. .
[0052]
The initial absorption part 35 is provided with a concave groove 36 as a first liquid transport part formed by processing the surface of the second sheet material 12 and the absorber 16 therebelow into a concave shape as shown in the figure, for example. It is formed inside by enclosing it with a concave groove 36.
The concave groove 36 is formed by pressing the second sheet material 12 and the absorber 16 from above in FIG. 4 by a method such as embossing, as shown in FIG. The portion to be formed is pressed and compressed to form a recess. In this case, the surface of the second sheet material 12 may not be processed, and a recess may be provided only in the absorber 16. As shown in FIG. 2, the concave groove 36 has a ring shape, and the inside thereof is a circular initial absorbing portion 35.
[0053]
Here, the first liquid transport unit 36 is formed by partially increasing the density of the absorber 16. That is, when the density of the absorber is partially increased, moisture can be quickly absorbed by capillary action as compared to the surrounding portion where the density is low. Therefore, when a region where the density of the absorber is increased along the direction in which the liquid component such as urine is desired to be conveyed, the liquid can be quickly conveyed in the direction.
As a preferred configuration example of such a liquid transport unit, the concave groove 36 is provided. That is, the absorbent body 16 is provided by increasing the density of the absorbent material under the groove by pressing the absorber 16 into a concave groove. Thereby, moisture is rapidly sucked into a portion where the density of the material under the groove is high due to capillary action.
[0054]
Therefore, the initial absorption part 35 is formed at a location where the user first hits the urine etc., and the urine etc. is not only directly absorbed by the initial absorption part 35 itself but also the first liquid. The transport unit 36 is rapidly sucked and transported around the initial absorption unit 35. Then, from the lower side of the concave groove 36 serving as the first liquid transporting portion, the initial absorption portion 35 made of an absorber having a low material density is absorbed and held from the periphery thereof.
[0055]
In addition, the first liquid transport unit is not limited to the concave groove 36 as described above, and even if the groove is not a concave groove, the thickness is the same and the absorber material in a predetermined region is higher than the surroundings. You may form by making it into a density.
[0056]
Furthermore, as shown in FIG. 2, the surface of the second sheet material 12 is provided with a second liquid transport unit. In this embodiment, the second liquid transport section is formed as four concave grooves 31, 32, 33, 34 that extend obliquely. The formation method of these grooves is the same as that of the above-described groove 36 and has the same structure (see FIG. 3). Accordingly, the concave grooves 31, 32, 33, and 34 are configured so that the second sheet material 12 and the absorber 16 are pressed from above as shown in the drawing and the groove portions are pressed and compressed to form concave portions. Alternatively, the surface of the second sheet material 12 may not be processed, and a recess may be provided only in the absorber 16.
In the illustrated case, each of the concave grooves 31, 32, 33, 34 is connected to the concave groove 36 around the initial absorption portion 35 at one end side, and the other end side extends obliquely, It reaches the corner of the absorber 16 below the second sheet material 12.
Therefore, on the surface of the second sheet material 12, virtual extensions inside the grooves 31, 32, 33, and 34 that are substantially X-shaped and concave with the initial absorption portion 35 as the center are the initial absorption portions 35. It is designed to intersect at the center.
[0057]
This embodiment is configured as described above, and the operation thereof will be described next.
Oshime 10 of this embodiment wears each region 21, 22, 23 of Oshime 10 explained in Drawing 2 according to each corresponding part of a user's body, respectively.
In such a wearing state, when the user discharges excrement such as urine, feces, blood and the like, it acts as follows.
[0058]
Preferably, the excretion part of the user's body abuts or faces the initial absorption part 35, and the excreted liquid component such as urine first hits the initial absorption part 35. In the case of urine excretion, a large amount of urine is released in a very short time. This large amount of urine and the like is not only directly absorbed by the initial absorption unit 35 itself but also the first liquid transport unit 36. As a result, the material is rapidly sucked into a region having a high material density below the groove 36 around the initial absorption portion 35 and conveyed in a ring shape. And it absorbs and holds from the circumference | surroundings with respect to the initial stage absorption part 35 which consists of an absorber with a thin material density from the lower side of the concave groove | channel 36 which is this 1st liquid conveyance part.
[0059]
On the other hand, urine or the like guided to the lower side of the groove 36 is below the concave grooves 31, 32, 33, 34, which are the second liquid transporting portion surrounding and surrounding the initial absorption portion 35. Absorbed to the side. Accordingly, a considerable portion of urine or the like does not stay in a partial region on the surface of the second sheet material 12, but extends below the groove along the extending direction of the concave grooves 31, 32, 33, 34. While moving quickly, the absorber 16 is absorbed from the periphery of the region having a high material density.
Here, in the illustrated case, each of the concave grooves 31, 32, 33, and 34 is connected to the concave groove 36 around the initial absorption portion 35, and a region where the material density is increased continues. Therefore, the liquid component can quickly move from the initial absorbing portion 35 to the concave grooves 31, 32, 33, 34 accordingly.
[0060]
As a result, liquid components such as urine are absorbed while spreading on all surfaces reaching the corner of the second sheet material 12, so that the urine and the like can be absorbed before the corner of the absorber 16 functions as in the prior art. The liquid component does not leak from the crotch portion of the fold 10.
[0061]
Here, since each of the concave grooves 31, 32, 33, 34 is connected to the groove 36 around the initial absorption portion 35, urine or the like absorbed under the groove 36 is immediately put into each groove 31. , 32, 33, 34 are absorbed underneath and have the effect of spreading quickly.
Therefore, it is preferable that the groove 36 completely surrounds the periphery of the initial absorption portion 35. However, even if part of the groove 36 is interrupted, if the groove 36 is connected to each of the grooves 31, 32, 33, 34, substantially the same effect is obtained. There is.
[0062]
Further, when the connection between the grooves 31, 32, 33, 34 and the groove 36 around the initial absorption part 35 is omitted due to manufacturing reasons, it is preferably located on the front side of the user's body. Only the grooves 32 and 33 may be connected, and the 31 and 34 may not be connected. Thereby, when the user wears the urine 10 and takes a sleeping posture, urine or the like can be guided to the front side of the user's body. Thereby, in this posture, it is possible to prevent urine or the like from being intensively guided behind the user and not being absorbed and leaking from the end on the back side.
[0063]
FIG. 5 is a top view showing a second embodiment of the present invention.
In the figure, the portions denoted by the same reference numerals as those in the first embodiment have a common configuration, and therefore, overlapping description will be omitted, and hereinafter, differences will be mainly described.
In the squeeze 40 of the second embodiment, the initial absorption portion 35 is provided at a position of the third region 23 corresponding to the front side of the body when worn as compared with the first embodiment.
[0064]
Moreover, the concave grooves 41, 42, 43, and 44 as the second liquid transporting portion extend in a dotted line shape as shown in the figure. That is, the embossed row forming each groove extends intermittently.
[0065]
The squeeze 40 according to the second embodiment is configured as described above, and exhibits the same operational effects as the first embodiment, but in addition to this, exhibits the following operational effects. That is, since the initial absorption part 35 is located in the 3rd area | region 23, especially regarding a male user, it can be made to respond | correspond to the excretion part. Thereby, in the case of a male user, the excretion part of the body tends to contact the initial absorption part 35. For this reason, since the excreted urine is immediately absorbed by the initial absorption part 35, it does not stay on the second sheet material 12.
[0066]
Moreover, the concave grooves 41, 42, 43, 44 are provided intermittently. For this reason, the liquid component absorbed in the region where the material density under the groove is high soaks into the absorber having a low material density at the portion where the groove is interrupted, but the portion where the material density under the groove following it is high Will be sucked further. In this way, liquid components such as urine are guided by the suction force acting along the direction in which the groove extends. As a result, excreted urine and the like are rapidly absorbed.
[0067]
FIG. 6 is a top view showing a third embodiment of the present invention.
In the figure, the portions denoted by the same reference numerals as those in the first embodiment have a common configuration, and therefore, overlapping description will be omitted, and hereinafter, differences will be mainly described.
In the urine 50 of the third embodiment, a first initial absorption part 51 and a second initial absorption part 52 are provided, and the first initial absorption part 51 is provided in the third region 23. The second initial absorber 52 is located in the second region 22.
[0068]
In addition, from the concave groove 36 that is the first liquid transport section around the first initial absorption section 51, the concave grooves 53, 54, and 55 that are the second liquid transport section in the direction corresponding to the back of the body. Is formed.
Of these, the grooves 53 and 55 extend obliquely toward the rear corner of the absorber, and the groove 54 extends rearward.
In the direction corresponding to the front of the body, the concave grooves 56, 57, and 58 that are the second liquid transport section are formed from the concave groove 36 that is the first liquid transport section around the second initial absorption section 52. Is formed.
Of these, the grooves 56 and 58 extend obliquely toward the front corner of the absorber, and the groove 57 extends forward.
[0069]
The present embodiment is configured as described above, and exhibits the same operational effects as the first embodiment and has the following operational effects.
The 1st and 2nd initial absorption parts 51 and 52 respond | correspond to each excretion part near the front part and crotch center of a user's body. For this reason, the liquid component from each excretion part can be absorbed and guided separately.
[0070]
In particular, the first initial absorption part 51 corresponds to the central part of the body, and since the grooves 53, 54, 55 extend rearward from this, when the user excretes in the sleeping state In addition, the liquid component excreted over the entire region of the absorber 16 corresponding to the back side of the urine 50 can be absorbed.
[0071]
In addition, since the concave groove 59 is provided between the first and second initial absorption parts, the liquid can be appropriately moved and absorbed between these.
[0072]
FIG. 7 is a top view showing a fourth embodiment of the present invention.
In the figure, the portions denoted by the same reference numerals as those in the first embodiment have a common configuration, and therefore, overlapping description will be omitted, and hereinafter, differences will be mainly described.
In the squeeze 60 according to the fourth embodiment, as compared with the first embodiment, the groove 61 that connects the end portions of the concave grooves 31 and 32 that are the second liquid transfer unit, and the grooves 33 and 34. The difference is that a groove 62 is provided to connect the end portions of the two. The concave grooves 61 and 62 are a third liquid transport unit.
[0073]
These grooves 61 and 62 extend along the side edge of the absorbent body 16 below the second sheet material 12. The side edge portion is located inside the crotch portions 17 and 18.
The structure of these grooves 61 and 62 is the same as the other concave grooves 31, 32, 32, 33.
[0074]
The present embodiment is configured as described above, and exhibits the same operational effects as the first embodiment and has the following operational effects.
Even when liquid components such as urine excreted by the user leak out in the lateral direction, which is the short direction of the product, before reaching the crotch portions 17 and 18, the lower side of the grooves 61 and 62 It is absorbed in places where the material density is high. As a result, it is prevented that the material under the groove is absorbed by the absorber 16 having a low material density and leaked to the outside.
Therefore, in the present embodiment, the grooves 61 and 62 as the third liquid transport unit guide urine and the like, and leakage from the crotch portion is almost complete by the action of the first and first flap portions 13 and 14. To be prevented.

In the figure, the portions denoted by the same reference numerals as those in the first embodiment have a common configuration, and therefore, overlapping description will be omitted, and hereinafter, differences will be mainly described.
Compared with the first embodiment, the urging 70 of the present embodiment is different in configuration of the first liquid transport unit 76 and the first liquid transport units 71, 72, 73, and 74.
That is, the first liquid transport unit 76 is a concave groove formed so as to surround the initial absorption unit 35, and in particular, an absorbent material is accommodated in the groove. Similarly, the second liquid transport units 71, 72, 73, 74 are concave grooves provided so as to extend obliquely from the initial absorption unit 35, and in particular, an absorbent material is accommodated in the grooves. Yes.
[0076]
FIG. 10 is a perspective view showing an enlarged portion of the groove 72 in order to show in detail the state in which the absorbent material is disposed in the concave groove as the liquid transport portion, and the first liquid transport portion is also shown in FIG. The second liquid transport unit has the same configuration.
In the drawing, as described above, the groove 79 which is a part of the second liquid transport unit presses the second sheet material 12 and / or the absorber 16 from above by a method such as embossing. It is formed so as to form a recess by pressing and compressing a portion that becomes a groove.
Thereby, the part 75 below the groove 79 of the absorber 16a is a region where the density of the material of the absorber is high. This part becomes the main body of the liquid transport unit. As described above, the liquid such as urine is rapidly transported to the portion 75 which is the main body of the liquid transport unit based on the capillary phenomenon.
[0077]
At this time, the liquid such as urine transported through the portion 75 is transported through the portion 75 while being absorbed to the other region side via the boundary portions 77, 77 with the other region of the absorber 16a. is there.
In the groove 79, for example, the above-described absorbent material 79 such as a polymer is disposed by a polymer spraying method in the manufacturing process. For this reason, the liquid conveyed through the portion 75 can be absorbed by the absorbent 79 in the groove 72 not only from the boundaries 77 and 77 but also from the boundary 78 above the portion 75.
For this reason, in the urine 70, not only can the operational effects of the first embodiment be exhibited, but in addition, a larger amount of liquid such as urine can be absorbed and held.
[0078]
Further, as shown in FIG. 10, the absorbent material 79 is not mixed in the absorbent body 16 a and is disposed in the groove 72, thereby collecting a predetermined amount of the absorbent material 79 in the groove 72 that is easily in contact with the liquid. Therefore, the expensive absorbent 79 can be functioned without waste.
Further, when more absorbent material 79 can be used, as shown in FIG. 11, it can be configured as a pulp absorbent material so as to be scattered not only in the groove 72 but also in the absorbent body 16a. In some cases, a larger amount of liquid can be absorbed and held.
[0079]
The present invention is not limited to the above-described embodiment.
In the above-described embodiment, squeeze has been described. However, the present invention can be applied to various products such as absorbent products other than squeeze, such as feminine sanitary products and auxiliary absorbent products for incontinence.
Further, a so-called pant-type product is also within the scope of the present invention by adding a significant configuration such as a fixing tape that is convenient for the user to wear to the urging shown in FIG.
Further, for example, in the urging 10 shown in FIG. 2, the regions 21 and 23 are slightly extended in the length direction, and both side edges of the regions 21 and 23 are overlapped and fixed so that they can be peeled off. It is the scope of the invention.
Moreover, you may combine each component of each above-mentioned embodiment arbitrarily.
[0080]
【The invention's effect】
As described above, according to the present invention, the liquid discharged by the wearer is quickly guided toward the end of the sheet material, and the absorbent is functioned in a wide range, thereby allowing the liquid such as urine to be discharged to the outside. It is possible to provide an absorbent product that can be completely sealed inside without leaking.
