Description

  The present invention relates to an absorbent article including a pant main body and an absorbent pad that is replaceably attached to the pant main body, and a pant main body constituting the absorbent article. The “absorbent article” in the present invention is intended for infants or nursing diapers, adult incontinence products, and the like.

  As an infant or nursing diaper, there is a pants-type disposable diaper in which an elastic member such as rubber is arranged in the opening around the waist and the opening around the leg, and the waist opening and the leg opening are respectively provided with elasticity. Are known. This pants-type disposable diaper is a combination of a pant body equivalent to a diaper cover and an absorbent body that absorbs and holds urine, etc., and is easy for the wearer to attach and detach. In the case of adults, it is possible to wear underwear.

  In order to reduce the economic burden on such disposable diapers, there are also incontinence pants that can be used repeatedly by washing and those that can be worn as an absorbent pad for the pants body to be exchangeable This is proposed in Patent Document 1, Patent Document 2, and Patent Document 3.

The incontinence pants described above are composed mainly of fabric in order to enable repeated use by washing, and are more comfortable to wear than pants-type disposable diapers. Can be said to be effective. In addition, the one that the absorbent pad can be exchangeably attached to the pant body is designed to hold the absorbent pad inside the pant body, and the pant body can be used repeatedly against the disposable absorbent pad. Is possible.

  In conventional pants-type disposable diapers, since the pant body and the absorbent body are integrated, if the wearer contaminates the absorbent body due to incontinence, etc., the entire pant body including the pant body has to be discarded. . For this reason, there is a drawback that the economic burden on the user side is significantly increased.

  The incontinence pants that can be used repeatedly by washing can reduce such an economic burden, but since the part that constitutes the absorbent body is mainly made of fabric, it is like an absorbent body used in disposable diapers. It does not have sufficient absorbency. For this reason, even if it can cope with light incontinence, there exists a problem that it cannot respond to normal urination or defecation.

  Although it is not as much as the incontinence pants mentioned above, it is more economical on the user side than the previous pants-type disposable diaper in that the absorbent pad can be exchanged on the inside of the pants body, although it is not as incontinence pants as mentioned above It is possible to reduce the burden. Moreover, depending on the ability of the absorbent pad, it can be adapted to normal leakage and defecation. However, when replacing the absorbent pad, especially in a bedridden sick person, the lower back is lifted off the bed, the pant body is slid down in this state, the absorbent pad is replaced, and then the pant body is re-regulated. It was necessary to pull it up to a position, and this work had a drawback that imposed a great physical burden on the caregiver. Such inconveniences occur in the same manner as incontinence pants and pants-type disposable diapers when care is given to a bedridden sick person or the like. In addition, when the pant body is pulled up to the normal position of the wearer, there is a possibility that the position of the absorbent pad may be shifted or bent.

[Object of invention]
The objective of this invention is providing the absorbent article which can replace | exchange an absorption pad easily and rapidly with respect to the underpants main body in a wearing condition.

  Another object of the present invention is to provide a pant body constituting such an absorbent article.

A first aspect of the present invention is a pant body having a waist opening, a pair of leg openings, and a liquid passage part, and an absorbent pad that is exchangeably joined from the outside of the pant body and covers the liquid passage part. And joining means for joining at least the front and rear ends of the absorbent pad to the pant body in a replaceable manner, wherein the liquid passage portion has a front opening for passing urine and a rear opening for passing stool. Yes and, in the absorbent article, wherein the further comprising an elastic member disposed in the lateral direction of the pants body between these front opening and the rear opening.

The elastic member for forming a gather around the waist and an elastic member for forming a gather around the waist and the stretch around the open end of the leg around opening to form a gather around the leg And an elastic member. In this case, it is possible to include an elastic member that is distribution along the lateral direction of the pants body during part of the elastic member is the front opening and the rear opening to form a leg gather.

  The absorbent pad can have joining means separable from the pant body at least at both longitudinal ends.

  The pant body has a liquid-permeable main sheet and a liquid-impermeable or liquid-repellent cover sheet that is integrally joined to a portion of the main sheet on which at least the absorbent pad around the liquid passage portion is overlaid. It may be.

  The absorbent pad may have a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between the two sheets. In this case, it may further include a liquid-impermeable or liquid-repellent cover sheet that is arranged so as to overlap the surface sheet and has an opening having a shape corresponding to the liquid passage portion. Further, the absorbent pad is provided with a pair of gather sheets arranged along the left and right side edges of the surface sheet, and an elastic for arranging the three-dimensional gathers in a stretched state on the free edge sides of the pair of gather sheets. And a member.

The second aspect of the present invention includes a waist opening, a pair of leg openings, and a liquid passage covered by an absorption pad that is exchangeably joined from the outside, and the liquid passage passes through the urine. possess a rear opening of the front opening and feces for passage of the use, the pants body, characterized by further comprising an elastic member that is disposed along the lateral direction between these front opening and the rear opening is there.

  According to the present invention, the pant body is worn such that the opening around the waist of the pant body surrounds the wearer's waist and the pair of opening around the leg surrounds the base of the wearer's leg. After that, attach the absorbent pad to the appropriate position of the pant body through the joining means so as to cover the liquid passage part of the pant body, but attach the absorbent pad to the pant body when wearing the pant body. Is also possible. The excrement of the wearer of the absorbent article is absorbed and held by the absorbent pad from the liquid passage portion of the pant body. If it becomes necessary to replace the absorbent pad, the absorbent pad holding the excrement is removed from the pant body through the joining means while wearing the pant body, and a new absorbent pad is removed from the pant body. The pants body is again mounted at an appropriate position through the joining means so as to cover the passage portion.

  The pant body in the present invention uses a single fiber such as cotton, polypropylene, polyethylene, polyester, nylon, or a composite fiber obtained by combining two or more kinds of polyester, polypropylene, polyethylene, nylon, etc., and a hydrophilic or hydrophobic nonwoven fabric. Although it can be composed of a woven fabric or the like, it is not limited to this, and an optimum one may be adopted according to the demand for the pant body. In order to improve the wearing feeling of the pant body, the pant body is divided into a plurality of parts such as the front body and the back body, and these are sewn together or joined together using an adhesive or heat seal, etc. It is desirable to form.

  As a joining means for joining the absorbent pad to the pant body in a replaceable manner, a hook-and-loop fastener or an adhesive tape can be used in addition to a button and a hook.

  The absorbent pad may have bonding means that can be separated from the pant body at least at both ends in the longitudinal direction.

  The top sheet of the absorbent pad can have the same or larger dimensions as the back sheet and may be composed of a single sheet, but is not limited to a single sheet, You may comprise by bonding a some sheet | seat, such as covering the left and right both sides edge part with a separate sheet | seat. When the front sheet is composed of a plurality of sheets, each sheet may use a different material, but the same material may be used. This surface sheet is made of a single fiber such as polypropylene, polyethylene, polyester, or nylon, or a composite fiber that is a combination of two or more of polyester, polypropylene, polyethylene, nylon, etc., and is hydrophilic or hydrophobic nonwoven fabric, woven fabric, porous It can be composed of a conductive plastic film. In particular, composite fibers of polyester / polyester, polyester / polyethylene, and polypropylene / polyethylene are preferable from the viewpoint of strength. However, the fiber is not limited to these, and an optimum fiber may be adopted according to the requirements for the surface sheet.

  The absorbent body of the absorbent pad is composed of cotton-like pulp, superabsorbent polymer (hereinafter abbreviated as SAP), hydrophilic sheet, etc., but is not particularly limited, and can be used for conventional diapers and other It may be a known absorber that is usually used for absorbent articles. That is, a single-layer or multi-layer mat made of absorbent fibers such as cotton pulp and rayon is covered with a hydrophilic sheet, and SAP is uniformly mixed in each mat or layered between each mat. Good. Or 3-60 weight% of heat-fusible substances may be mixed and thermocompression bonded to the cotton-like pulp, or only SAP may be surrounded by a hydrophilic sheet.

  As the above-described hydrophilic sheet, tissue, absorbent paper, hydrophilic nonwoven fabric and the like can be employed.

The cotton-like pulp having a fiber length of 5 mm or less obtained by defibrating a chemical pulp sheet or a mechanical pulp sheet with a pulverizer is used. The pulp raw material is not limited to conifers, but hardwoods, straw, bamboo, kenaf, and the like can be used, and waste paper pulp may be used. The amount of use of the cotton-like pulp varies depending on whether it is used singly according to the absorption characteristics of the target absorbent pad, a plurality of layers are used, or other absorbents are used together. Set to ˜400 g / m ² .

  SAP absorbs water such as urine and body fluid 20 times or more of its own weight, and examples thereof include starch-based, cellulose-based, and synthetic polymer-based ones. That is, starch-acrylic acid (salt) graft copolymer, saponified product of starch-ethyl acrylate graft copolymer, saponified product of starch-methyl methacrylate graft copolymer, saponified product of starch-acrylonitrile graft copolymer Saponified starch-acrylamide graft copolymer, acrylic acid (salt) polymer, polyethylene oxide cross-linked with acrylic acid, cross-linked product of sodium carboxymethyl cellulose, cross-linked product of polyvinyl alcohol-maleic anhydride reaction product, etc. In particular, a sodium polyacrylate type is most preferable from the viewpoint of absorption performance. The amount of SAP distributed is 10 to 500 parts by weight, preferably 15 to 300 parts by weight, based on 100 parts by weight of the dried cotton-like pulp, and is distributed substantially uniformly on the cotton-like pulp. When SAP absorbs urine and body fluids and swells, the interference between the particles is minimized, it is less likely to contact continuously to form a permeation barrier, and urine and body fluids are transmitted in three dimensions. It is desirable to absorb it.

  In order to improve the sense of incongruity with the absorbent pad when worn, it is effective to compress the absorbent body to increase the bulk density. Specifically, the outer peripheral surface may be compressed into a continuous surface so that the density of the absorber becomes substantially uniform over the whole by a roll having a smooth outer peripheral surface, or irregularities are formed on the outer peripheral surface. It is also effective to subject the absorbent body to embossing with a partially different bulk density by the formed roll or the like, and to compress and mold the urine, body fluid, etc. in the longitudinal direction or the oblique direction. When this embossing is performed, the compressed portion and the non-compressed portion may be either continuous or discontinuous.

  The shape of the absorbent body may correspond to the contour shape of the liquid passage portion, but it does not necessarily have to correspond, and may be rectangular or hourglass type, and is usually used in conventional disposable diapers and other absorbent articles. Any known shape may be used and is not particularly limited.

  When a liquid-impermeable or liquid-repellent cover sheet is disposed on the top sheet of the absorbent pad, the top sheet itself may have liquid diffusibility. Alternatively, it is also effective to interpose a diffusion sheet as a diffusion layer in at least a part of the surface layer side of the absorber facing the surface sheet. Even if it is difficult to form a sufficient gap for trapping between the topsheet and the absorber due to the wearer's body shape and wearing condition, urine and body fluids can be quickly transferred to the absorber via this diffusion sheet. Therefore, leakage of urine, body fluid, etc. can be prevented without reducing the absorption rate by the absorber. The diffusion sheet is made of polypropylene, polyethylene, polyester, rayon, pulp, or composite fibers of these, and is composed of hydrophilic and liquid-permeable nonwoven fabric, woven fabric, porous plastic, cotton pulp, etc. Although it fixes using an adhesive etc. between the bodies or the surface of an absorber, it is not specifically limited to these.

  The back surface sheet of the absorbent pad can be composed of a liquid-impermeable film such as polyethylene, a laminated material of a liquid-impermeable film and a nonwoven fabric, a laminated material of a liquid-impermeable film and a woven fabric, or the like. .

  The gathered sheet placed on the absorbent pad uses a single fiber such as polypropylene, polyethylene, polyester, nylon, or a composite fiber that combines two or more types of polyester, polypropylene, polyethylene, nylon, etc., and has a hydrophilic or hydrophobic nonwoven fabric. Consists of woven fabric and porous plastic film. In particular, composite fibers of polyester / polyester, polyester / polyethylene, and polypropylene / polyethylene are preferable from the viewpoint of strength, but the structure of the gather sheet is not limited thereto.

  It is also possible to form a gather sheet by extending the top sheet or the back sheet from the left and right side edges, but the above-described diffusion sheet or a sheet independent of these is used as the top sheet or the back sheet. It is also possible to form them by bonding them together.

  Elastic members for forming gathers around the waist, elastic members for forming gathers around the legs, and elastic members for forming three-dimensional gathers are all made of natural rubber, synthetic rubber, urethane, etc. Joined in a stretched state using a hot melt, starch-based or water-soluble glue such as CMC (carboxymethylcellulose) or a high-flow adhesive, heat, ultrasonic waves, etc. To do.

  According to the absorbent article of the present invention, the liquid passage part is formed in the pant body, and the absorbent pad that covers the liquid passage part is joined from the outside of the pant body through the joining means in an exchangeable manner. It is possible to quickly replace only the absorbent pad at a very easy and appropriate position from the outside while wearing it, and it is possible to reduce the economic burden by repeatedly using the pant body. is there. In addition, since it is not necessary to take off the pant body when replacing the absorbent pad, the physical burden and shame of the wearer can be further reduced, particularly as an absorbent article for nursing care. Furthermore, since the liquid passage part has a front opening for urine passage and a rear opening for stool passage, urine and stool can be separated and urine can be quickly guided to the absorption pad side and absorbed, Processing such as stool is also possible.

  An elastic member for forming a gather around the waist is arranged in an extended state along the opening end of the opening around the waist of the pant body, while an elastic member for forming a gather around the leg is arranged at the opening end of the leg opening. When arranged along the stretched state, it is possible to improve the feeling of wearing the pants body.

  When joint means that can be separated into the pant body is provided at least at both ends in the longitudinal direction of the absorbent pad, the absorbent pad can be easily attached and detached.

  When the pant body has a liquid-permeable main sheet and a liquid-impermeable or liquid-repellent cover sheet that is integrally joined to the main sheet portion on which at least the absorbent pad around the liquid passage portion is overlaid In this case, the part of the skin of the wearer that is in contact with the pant body around the liquid passage part can be kept dry to further reduce the discomfort.

  When the absorbent pad has a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body disposed between the two sheets, the absorbent sheet is directly applied to the wearer's skin by the top sheet. Leakage can be reliably prevented by the back sheet without touching.

  A pair of gather sheets in which the absorbent pads are arranged along the left and right side edges of the surface sheet; and an elastic member arranged in an extended state on the free end edges of the pair of gather sheets to form a three-dimensional gather respectively. When it has, it can prevent the leakage from the left and right side edges of the absorbent pad.

  According to the pant main body of the present invention, the pants main body is provided with the waist-periphery opening, the pair of leg-periphery openings, and the liquid passage covered by the absorbent pad that is exchangeably joined from the outside. If necessary, only the absorbent pad can be quickly replaced from the outside to a very easy and appropriate position, and the economical burden can be reduced by repeatedly using the pant body. In addition, since it is not necessary to take off the pant body when replacing the absorbent pad, the physical burden and shame of the wearer can be further reduced, particularly as an absorbent article for nursing care. Furthermore, since the liquid passage part has a front opening for urine passage and a rear opening for stool passage, urine and stool can be separated and urine can be quickly guided to the absorption pad side and absorbed, Processing such as stool is also possible.

  Examples of the absorbent article according to the present invention will be described in detail with reference to FIG. 1 to FIG. 29 together with reference examples thereof. However, the present invention is not limited to these examples, and these may be further combined, All changes and modifications encompassed by the inventive concept described in the claims of the present invention are possible, and can of course be applied to any other technique belonging to the spirit of the present invention.

  FIG. 1 is a perspective view showing a state where an absorbent pad 11 and a pant body 12 of an absorbent article in a reference example as incontinence pants are separated. FIG. 2 is a partially cutout development view of the absorbent pad 11. In FIG. 1 and FIG. 2, the absorbent pad 11 is a sheet in which an absorbent body 15 is disposed between a liquid-permeable top sheet 13 and a liquid-impermeable back sheet 14 and extends from the side edge of the absorbent body 15. Side flaps 16 are formed at the portions, and a joining means 17 for the pant body 12 is provided at portions located at both longitudinal ends of the front body portion 11F and the back body portion 11R. The pant body 12 has a back body part 12R, a crotch part 12C, and a front body part 12F, and a liquid permeable sheet 18 (area shown by slant lines in the figure) is disposed in the crotch part 12C. The joining means 19 with the absorption pad 11 is provided in 12R and the front body part 12F.

  The pant body 12 having the waist opening 12W and the pair of leg openings 12L is integrated with the absorbent pad 11 by the joining means 17 and 19 when worn. When urinating in a toilet or the like, Similarly, the absorbent pad 11 can be attached and detached. For this reason, it is very excellent in fit and can be mounted without a sense of incongruity. In addition, when incontinence occurs, only the absorbent pad 11 disposed outside is removed and the new absorbent pad 11 is disposed without taking off the pant body 12, which is not only very convenient, but also the lower body Because it is not necessary to expose, shame can be reduced.

  Generally used disposable pants-type diapers can be easily removed by removing the joints formed on both sides of the abdomen and dorsal side when the part of the absorbent pad 11 becomes dirty due to incontinence, In order to put on a new disposable pants-type diaper, it was necessary to take off the pants once and then put it on again. In addition, since not only the absorbent pad 11 but also the pant body 12 is discarded, the cost is high and the economic burden is large. Even if the urine pad placed inside the disposable pants-type diaper is replaced, for a wearer who can detach the pant by himself, the act of lowering the pant and exposing the lower body to replace the urine pad , To promote shame. In addition, the urine pad placed on the inside is bent when the wearer pulls up the disposable pants-type diaper, and the liquid-impermeable back sheet comes to the wearer's skin and cannot absorb urine during urination There was also a problem of leaking.

  In this reference example, both the absorbent pad 11 and the pant body 12 have the joining means 17 and 19, but it is only necessary to be able to couple them, and only one of the joining means 17 and 19 may be disposed. For example, when the sheet of the pant body 12 is made of cotton or a non-woven fabric with good fluff, and the joining means 17 of the absorbent pad 11 is made of hook material of a hook-and-loop fastener, the pant body 12 is particularly bonded. The means 19 need not be provided. Moreover, there is no problem even if these materials are arranged oppositely between the pant body 12 and the absorbent pad 11. When the bonding means 17 is provided only on the absorbent pad 11 and can be bonded anywhere on the pant body 12, the bonding means 19 can be easily integrated without defining the bonding means 19, which is very simple. Conversely, when the joining means 19 is provided only on the pant body 12 and the joining means 17 is not provided on the absorbent pad 11, it is not necessary to place an extra member on the absorbent pad 11 that is discarded every time after urination. Manufacturing becomes possible and the economic burden can be reduced.

  The binding position of the absorbent pad 11 in this reference example is the front body part 12F and the back body part 12R, but may be the front body part 12F and the crotch part 12C. When used at night or the like, it is necessary to arrange the absorption pad 11 up to the back body part 12R for the purpose of absorption at the wearer's buttocks in the supine state, but the front body part 12F and the crotch part only during the day Only 12C may be used. In the case of only the front body part 12F and the crotch part 12C, the absorbent pad 11 is also shortened in the longitudinal direction and can be manufactured at low cost. Moreover, when a wearer replaces, it is not necessary to turn a hand to the back body part 12R at the time of mounting | wearing with the absorption pad 11, and attachment / detachment becomes still simpler.

  When the liquid permeable sheet 18 is separately disposed in the crotch portion 12C of the pant body 12, the length may be the same as that of the absorbent pad 11, but it may be disposed only at the urination site of the wearer. Preferably, it has a length equivalent to that of the absorbent pad 11 so that it can cope with the flow of excrement due to the posture of the wearer during urination. Further, at least the liquid permeable sheet 18 has a smaller moisture retention amount than the top sheet 13 of the absorbent pad 11 and has a good feeling of slats.

  In FIG. 2, the absorbent pad 11 is a sheet portion in which an hourglass-shaped absorber 15 is disposed between a liquid-permeable top sheet 13 and a liquid-impermeable back sheet 14, and extends from a side edge of the absorber 15. The side flap 16 is formed. The absorbent pad 11 has a back body part 11R, a crotch part 11C, and a front body part 11F. The back body part 11R and the front body part 11F are arranged at the positions of both ends in the longitudinal direction of the absorbent pad 11 when worn. A joining means 17 is provided on the top sheet 13 side so that the part 11R and the front body part 11F are joined to the pant body 12.

  The width dimension of the crotch part 11C of the absorbent pad 11 corresponding to the crotch part 12C of the pant body 12 may be the same width as the crotch part 12C of the pant body 12 or may be different. When the width is the same, there is no wobbling in the crotch portion when worn, and the fit is good. When the width of the absorbent pad 11 is wider than the pant body 12, a gap is formed between the pant body 12 and the absorbent pad 11 in the crotch portion 12C, and this gap temporarily holds urine even when the absorbent pad 11 is thinned. It becomes an area, prevents leakage, and can be used suitably.

  You may arrange | position an elastic member around a leg and a three-dimensional gather along the longitudinal direction in the both sides of the absorption pad 11. FIG. The leg-hole elastic member is disposed between the top sheet 13 and the back sheet 14 in the region of the crotch portion 11 </ b> C of the absorbent pad 11.

  The three-dimensional gather may be inward, but a three-dimensional gather such as a C-fold or a Z-fold that is folded over or part of the three-dimensional gather may be arranged. There is no need for a pair when arranging, and a plurality of sets of solid gathers may be arranged by appropriately combining them. Moreover, although the elastic member which forms a three-dimensional gather may be one, multiple may be arrange | positioned. The base end portion of the three-dimensional gather may be installed on the outer side in the width direction of the absorbent body 15, but may be on the absorbent body 15 or the elastic member around the leg, and is not particularly limited.

  The height of the three-dimensional gather is 5 mm or more and 100 mm or less. If the excrement stays on the absorbent pad 11 if it is less than 5 mm, it cannot be a sufficient weir. If it exceeds 100 mm, the upper surface of the absorbent pad 11 is covered with the crotch portion 12 </ b> C, which may cause leakage, or a three-dimensional gather extends to the outside of the absorbent pad 11, which causes urine to flow outside the absorbent pad 11. It becomes a flow path and may cause leakage.

  The absorber 15 does not need to be an hourglass shape, and may be a rectangle or a T-shape. When the absorbent pad 11 is disposed only from the front body part 12F of the pant body 12 to the crotch part 12C, it is preferably T-shaped in order to improve the fit between the crotch parts, but is not particularly limited.

  3-5 is a figure of the Example different from FIG. 2, and has shown arrangement | positioning of the joining means 17 of the absorption pad 11. FIG. In the embodiment of FIG. 3, the bonding means 17 is arranged around the absorption pad 11. In this case, there is no gap between the absorbent pad 11 and the pant body 12, and the leakage prevention effect is high. In the embodiment shown in FIG. 4, the joining means 17 is arranged in a U shape on both ends in the longitudinal direction of the absorbent pad 11 and on both sides near both ends. In this case, when a leg elastic member and a three-dimensional gather are arranged in the crotch portion 11C of the absorbent pad 11, it is difficult to gather together with the pants body 12 due to the gather on the absorbent pad 11 side, This is suitable for the case where it is not desired to limit the movement of the absorbent pad 11 by surrounding movement. In the embodiment shown in FIG. 5, the joining means 17 is disposed only at a part of both ends in the longitudinal direction of the absorbent pad 11. In this case, since the arrangement area of the joining means 17 becomes small, it can be manufactured at low cost and is highly economical.

  These joining means 17 are not limited to these examples, and the embodiment shown in FIG. 2 and the embodiments shown in FIGS. 4 and 5 may be appropriately combined. Further, the joining means 19 of the pant body 12 can be appropriately changed according to the arrangement position of the joining means 17 of the absorbent pad 11.

  Moreover, when arrange | positioning the joining means 19 only to the underpants main body 12, there exists the method of arranging various according to the reference example of the arrangement position of these absorption pads 11, and it does not specifically limit.

  FIG. 6 is a development view showing an example of the pant body 12 of FIG. This is an example of cloth shorts. In FIG. 6, the pant body 12 has a front body portion 12F, a crotch portion 12C, and a back body portion 12R, and the crotch portion 12C has high liquid permeability and moisture retention. A low liquid-permeable sheet 18 (area shown by slanting lines in the figure) is disposed, and the front body part 12F and the back body part 12R are hygroscopic, and a stretchable main sheet 20 is separately disposed. . The left and right side flaps 16 'of the rear body part 12R are joined to form a belt, and the end part of the front body part 12F is overlapped and sewn on the lower part to form the pant body 12. In the present reference example, both side regions of the left and right side flaps 16 ′ of the back body part 12 </ b> R in FIG. 6 form a part of the front body part 12 </ b> F of the pant body 12.

  In order to enhance the fit around the waist and legs of the pant body 12, an elastic member may be separately provided.

  When the entire pant body 12 is formed of a material having high liquid permeability and low moisture retention, the crotch portion 12C, the front body portion 12F, and the back body portion 12R need not be separated and may be the same.

  FIG. 7 shows a reference example different from FIG. 6, and is a development view of the pant body 12 of FIG. In FIG. 7, the liquid permeable sheet 18 is arranged over the entire length in the longitudinal direction in the center region in the width direction of the pant body 12 (the region indicated by the slanted line in the drawing). Leg leg elastic members 21 for forming leg leg gathers 21G (see FIG. 1) are arranged. In addition, waist elastic members 22 for forming waist circumference gathers 22G (see FIG. 1) are disposed at both ends in the longitudinal direction. A side sheet 23 having elasticity is disposed on the side flap 16 ′ of the pant body 12, which may be the same as the main sheet 20. The pants body 12 is formed by bonding the side flaps 16 'of the front body part 12F and the back body part 12R.

  FIG. 8 shows a reference example different from FIGS. 6 and 7, and is a development view of the pant body 12 of FIG. In FIG. 8, a liquid-permeable sheet 18 is disposed in the central region in the longitudinal direction of the pant body 12 (the region indicated by the oblique lines in the figure), and is curved from the rear body portion 12R and the front body portion 12F at the crotch portion 12C. The leg elastic members 21 form a leg gather. Further, elastic members 22 around the waist are arranged at both ends in the longitudinal direction. The pants body 12 is formed by bonding the side flaps 16 'of the front body part 12F and the back body part 12R.

  The leg-around elastic members 21 do not necessarily need to intersect at the crotch portion 12C. Moreover, it can also be set as the structure which is not arrange | positioned.

  The configuration method of the pant body 12 is not limited to these FIGS. As long as the shape of the pants is maintained, the liquid permeable sheet 18 as the liquid passage portion is preferably disposed in the region of the crotch portion 12C, and the coupling means 19 with the absorbent pad 11 is provided.

  In the reference example described above, incontinence pants are intended as an absorbent article, but an elongated crotch opening extending from the lower part of the front body part 12F of the pant body 12 to the lower part of the rear body part 12R through the crotch part 12C is formed. In some cases, it can be used for defecation.

  The appearance of another reference example of such an absorbent article is shown in an exploded state in FIG. 9, the central vertical cross-sectional shape of the main part is shown in FIG. 10, and the pant body part is expanded and shown in FIG. The elements having the same functions as those of the previous reference example are denoted by the same reference numerals, and redundant description is omitted.

  In FIG. 9, the absorbent pad 11 includes an absorbent body 15 disposed between a liquid-permeable top sheet 13 and a liquid-impermeable back sheet 14, and a sheet portion extending from the side edge of the absorbent body 15. Side flaps 16 are formed, and joining means 17 for the pants body 12 are provided at both ends of the absorbent pad 11 in the longitudinal direction. The pant body 12 includes a back body part 12R, a crotch part 12C, and a front body part 12F. A crotch opening 24 is formed in the crotch part 12C, and the back pad part 12R and the front body part 12F are connected to the absorbent pad 11. A joining means 19 is provided.

  When this absorbent article is worn, the absorbent pad 11 and the pant body 12 are integrated by the joining means 17 and 19, and when it is desired to urinate in a toilet or the like, the absorbent pad 11 can be attached and detached in the same manner as normal pants. It is. For this reason, it is very excellent in fit and can be mounted without a sense of incongruity. Further, when incontinence occurs, it is very simple because only the absorbent pad 11 disposed outside is removed and the new absorbent pad 11 is disposed without removing the pant body 12.

  Generally used disposable pants-type diapers can be removed easily by removing the abdomen and dorsal side joints when the absorbent main body becomes dirty due to incontinence. To put it on, it was necessary to take off the pants once and then put it on again. In addition, since not only the absorbent pad but also the pant body 12 is discarded, the cost is high and the economic burden is high. Even when replacing the urine pad placed inside the disposable pants-type diaper, the urine pad placed inside is folded when the wearer pulls up the disposable pants-type diaper, and is a liquid-impermeable back sheet However, there was a problem that it came to the wearer's skin and leaked without being able to absorb urine during urination.

  In this reference example, both of the absorbent pad 11 and the pant body 12 have the joining means 17 and 19, but it is only necessary to be able to join both, and only one of the joining means 17 and 19 is disposed. But it ’s okay. For example, when the pant body 12 sheet is made of cotton or non-woven fabric with good fluff, and the joining means 17 of the absorbent pad 11 is made of hook material of hook-and-loop fastener, it is necessary to provide the joining means 19 in the pant body 12 in particular. Absent. Moreover, there is no problem even if these materials are arranged oppositely between the pant body 12 and the absorbent pad 11. When the joining means 17 is provided only on the absorbent pad 11 and can be joined anywhere on the pant body 12, the joining means 19 can be easily integrated without defining the joining means 19, which is very simple. On the contrary, when the joining means 19 is provided only on the pant body 12 and the joining means 17 is not provided on the absorbent pad 11, it is not necessary to place an extra member on the absorbent pad 11 that is discarded every time after urination. Can be reduced and the economic burden can be reduced.

  As shown in FIGS. 9 to 11, the pant body 12 in the present reference example has one crotch opening 24 formed in the crotch part 12 </ b> C of the pant body 12. The crotch opening 24 has a size including at least a urination position and a defecation position. The position and size may be different between men and women, or may be a position and size that can cover both. . Preferably, it is better to set the urination position and the defecation position to be large so that the urination position and the defecation position enter the crotch opening 24 even for a slight deviation. In this reference example, any excretion can be handled by the crotch opening 24 that can cover both the urination position and the defecation position.

  12 to 14 are development views of the pant body 12 respectively showing different examples of openings formed in the pant body 12.

  FIG. 12 shows a reference example in which a front opening 25 is formed at the urination position of the crotch portion 12 </ b> C of the pant body 12. The front opening 25 has a size including at least a urination position, and the position and size may be divided between men and women, or may be a position and size that can cover both. In the case of men, the size may be such that only the penis is passed through, or the size up to the testicles may be used. Preferably, the size is such that only the penis is passed. Moreover, it is good also as a structure used by making the opening part 25 into a slit shape and pinching a wearer's penis part in this slit. By placing the testicles in the pant body 12, the testicles are not contaminated by urine and the like, and fogging can be prevented. In this reference example, defecation is possible in the toilet, but it is possible to deal with cases where only urination leaks.

  FIG. 13 shows a reference example in which one rear opening 26 is formed at the defecation position of the crotch portion 12 </ b> C of the pant body 12. The rear opening 26 is sized to include at least the defecation position. In this reference example, it is possible to cope with cases where the urethra is connected to the intestine due to surgery and leakage occurs only from the anus, or due to sudden constipation due to sudden constipation due to taking medicine, etc. is there.

  FIG. 14 shows an embodiment in which a front opening 25 and a rear opening 26 are formed in the crotch portion 12C of the pant body 12. These two openings 25 and 26 are formed corresponding to at least the urination position and the defecation position, and the front opening 25 at the urination position may be divided in position and size between men and women, or both The thing of the position and the size which can be covered may be sufficient. The two openings 25 and 26 may have the same size, but may have different sizes. In this embodiment, the two openings 25 and 26 are formed at both the urination position and the defecation position, so that any excretion can be handled.

  15 to 18 are developed plan views in a state where the absorbent pad 11 is disposed on the pant main body 12.

  FIG. 15 shows an embodiment in which the absorbent pad 11 is arranged from the front body portion 12F to the back body portion 12R, and is effective for all the reference examples and embodiments described above. That is, even when only the front opening 25 is formed corresponding to the urination position or only the rear opening 26 is formed corresponding to the defecation position, the absorbent pad 11 is removed from the front body 12F. By disposing over the entire portion 12R, even if excrement flows, it can be easily absorbed, and in the case of defecation, a large gap is formed between the pants body 12 and the absorbent pad 11. Therefore, the leakage prevention effect is also enhanced.

  FIG. 16 is a reference example in which the absorbent pad 11 is arranged from the front body part 12F to the crotch part 12C. In the case of incontinence pants, by arranging the absorbent pad 11 only from the front body part 12F to the crotch part 12C, the absorbent pad 11 is shortened in the longitudinal direction and can be manufactured at low cost. Further, the wearer does not need to turn his / her hand to the back body portion 12R when the absorbent pad 11 is mounted, and the attachment / detachment is further simplified.

  FIG. 17 is a reference example in which the absorbent pad 11 is arranged from the crotch portion 12C to the back body portion 12R. When only the rear opening 26 is formed according to defecation, the absorbent pad 11 is shortened in the longitudinal direction by arranging the absorbent pad 11 only from the crotch portion 12C to the rear body portion 12R, and can be manufactured at low cost. . Moreover, in this case, it can be set as the absorption pad 11 only for a flight. Since the stool-specific absorption pad 11 does not need to absorb urine, it is only necessary to arrange a very small amount of the absorber 15 and can be manufactured at a very low cost. It is also possible to make the absorbent pad 11 with the absorber 15 completely eliminated.

  FIG. 18 shows an embodiment in which the absorption pads 11 are arranged at the urination position and the defecation position, respectively. The two absorbent pads 11 may be the same, but may have different configurations. When the two absorbent pads 11 are arranged, the only part that gets wet by urination is from the front body part 12F to the crotch part 12C. Further, since the stool does not spread to the urination site, it also prevents infection from the urination site. Furthermore, since the part which becomes dirty with feces is only in the vicinity of the rear opening 26 of the defecation part, cleaning of the skin and the like is simple.

  19 to 22 are plan views respectively showing the arrangement state of the bonding means 17 of the absorbent pad 11.

  In the embodiment shown in FIG. 19, the bonding means 17 is arranged around the absorption pad 11. In this case, there is no gap between the absorbent pad 11 and the pant body 12, and the leakage prevention effect is high.

  FIG. 20 shows an embodiment in which the joining means 17 is arranged in the shape of a key at both ends in the longitudinal direction of the absorbent pad 11. In this case, when the elastic members around the legs are arranged in the crotch portion 11C of the absorbent pad 11, it is difficult to attach the pants body 12 tightly due to gathers on the absorbent pad 11 side, This is suitable when the movement of the absorbent pad 11 is not desired to be restricted.

  FIG. 21 shows an embodiment in which the joining means 17 is arranged only at both ends in the longitudinal direction of the absorbent pad 11. In this case, since the arrangement area of the joining means 17 becomes small, it can be manufactured at low cost and is highly economical.

  FIG. 22 shows an embodiment in which the joining means 17 is arranged only at a part of both ends in the longitudinal direction of the absorbent pad 11. In this case, since the arrangement area of the joining means 17 is further reduced, it can be manufactured at low cost, is highly economical, and can follow up without obstructing the expansion and contraction of the pant body 12 around the waist due to the movement of the wearer. Become.

  The embodiments shown in FIGS. 20 to 22 can be appropriately combined to set the arrangement of the joining means 17. Further, the joining means 19 of the pant body 12 can be appropriately changed according to the arrangement position of the joining means 17 of the absorbent pad 11.

  Moreover, when arrange | positioning one joining means 19 in the underpants main body 12, there exists the method of arrange | positioning variously according to the arrangement position of these absorption pads 11, and it does not specifically limit.

  FIG. 23 is another developed view of the pant body 12 of FIG. In FIG. 23, the pant body 12 has a front body part 12F, a crotch part 12C, and a back body part 12R. A crotch opening 24 is formed in the crotch part 12C, and the whole is constituted by the main seat 20. The main sheet 20 is stretchable and preferably hygroscopic. The pants body 12 is formed by joining the left and right side flaps 16 'of the rear body part 12R to form a belt and joining the end of the front body part 12F to the lower part.

  In order to improve the fit around the waist and legs of the pant body 12, an elastic member may be separately arranged. An elastic member may be disposed over a part or the entire periphery of the crotch opening 24.

  The pant body 12 does not need to be composed of only a single main sheet 20, and a pant body can be formed by connecting or overlapping a plurality of sheets having different properties.

  FIG. 24 shows a reference example different from FIG. 23 and shows a developed state of the pant body 12 of FIG. In FIG. 24, a front opening 25 is disposed at the urination position of the crotch portion 12C of the pant body 12, and the leg-around elastic member 21 is disposed along the left and right side edges of the crotch portion 12C. Further, elastic members 22 around the waist are disposed on both sides in the longitudinal direction. The pants body 12 is formed by bonding the side flaps 16 'of the front body part 12F and the back body part 12R.

  The elastic member may be arranged over a part or the entire circumference of the front opening 25. In addition, the side flap 16 ′ of the pant body 12 can be formed of a sheet having elasticity different from that of the main sheet 20.

  FIG. 25 shows an embodiment of the present invention and shows the developed shape of the pant body 12 of FIG. In FIG. 25, a front opening 25 and a rear opening 26 are respectively disposed at the urination position and the defecation position of the crotch part 12C of the pant body 12, and the back body part 12R and the front body part 12F are located at the crotch part 12C. A leg circumference gathering is formed by the leg circumference elastic members 21 arranged curvedly. Further, elastic members 22 around the waist are arranged at both ends in the longitudinal direction. The pants body 12 is formed by bonding the side flaps 16 'of the front body part 12F and the back body part 12R to each other.

The leg-around elastic members 21 do not necessarily need to intersect at the crotch portion 12C . This may be arranged an elastic member over a portion or the entire circumference of the periphery of these two openings 25, 26.

  The pant body 12 does not need to be composed of only a single main sheet 20, and the pant body 12 can be formed by connecting or overlapping a plurality of sheets having different properties.

  The configuration of the pant body 12 is not limited to the reference examples and examples shown in FIGS. 11 to 14 and FIGS. 23 to 25. As long as the shape of the pants is maintained, it is sufficient that at least one of the openings 24 to 26 is provided. Moreover, the formation method of the underpants main body 12 and the positions, sizes, and numbers of the openings 24 to 26 are not particularly limited, and any combination may be used.

  FIG. 26 shows a partially broken plan view of the absorbent pad 11 in the present embodiment, and FIG. 27 shows a sectional structure taken along the line XXVII-XXVII. That is, the absorbent pad 11 in the present embodiment includes a liquid-impermeable top sheet 13, a liquid-impermeable back sheet 14, an absorber 15 disposed between the two sheets 13 and 14, and a top sheet. 13 and the water-repellent cover sheet 28 which are respectively joined to the left and right edge portions of the back sheet 14 and are arranged so as to cover the top surface of the top sheet 13 and have an opening 34 at the position of the crotch portion 11C. And a pair of joining means 17 provided on the upper surface of the cover sheet 28. In the present embodiment, the elastic members 31 are arranged in an expanded state along both longitudinal edges of the opening 34 formed in the cover sheet 28, thereby forming a three-dimensional gather 30. In this embodiment, a diffusion sheet 32 that covers the surface of the absorbent body 15 is interposed between the absorbent body 15 and the top sheet 13, and the absorbent body 15 is wrapped with tissue 33 together with the left and right side edges of the diffusion sheet 32. It is in the state. The diffusion sheet 32 has a function for quickly diffusing a liquid such as urine over the entire surface of the absorber 15. The absorbent pad 11 in the present embodiment has the same width dimension at both ends in the longitudinal direction, but can be set to an arbitrary shape along the crotch portion 12C.

  In this embodiment, an opening 34 having a shape corresponding to the crotch opening 24 of the pant body 12 is formed on the surface of the cover sheet 28, and the opening 34 of the cover sheet 28 and the crotch opening 24 are in communication with each other. When the absorbent pad 11 is attached to the pant body 12 as described above, urine passes through the surface sheet 13 from the opening 34 of the cover sheet 28 of the absorbent pad 11 and is guided to the diffusion sheet 32, so that the outer surface of the pant body 12 is urine. Can be prevented from getting wet. From such a viewpoint, it is effective to set the opening 34 of the cover sheet 28 to be smaller than the crotch opening 24 of the pant body 12. Further, the front body portion 12F and the crotch portion 12C of the pant body 12 overlapping the absorption pad 11 can be made liquid permeable, and urine can be quickly guided to the absorption pad 11 side from other than the crotch opening 24. Is possible.

  The width of the crotch portion 11C of the absorbent pad 11 may be set to the same width as that of the crotch portion 12C of the pant body 12, but may be different. When the width is the same, there is no wrinkle in the crotch part when wearing, and the fit is good. When the width of the absorbent pad 11 is wider than the crotch part 12C of the pant body 12, a gap is formed between the pant body 12 and the absorbent pad 11 in the crotch part 12C, and this gap is not reduced even when the absorbent pad 11 is thinned. Since urine etc. can be temporarily hold | maintained by this, leakage can be prevented and it can be used conveniently.

  You may arrange | position a leg periphery elastic member in the both sides along the longitudinal direction of the absorption pad 11. FIG. The leg-around elastic member is disposed between the cover sheet 28 and the back sheet 14 located in the crotch portion 11 </ b> C of the absorbent pad 11. The elastic members around the legs may be arranged in parallel, but may be curved or arranged in a square shape.

  The three-dimensional gather 30 may be formed by arranging a belt-like gather sheet in the longitudinal direction of the absorbent pad 11 in addition to the cover sheet 28. In this case, the three-dimensional gather 30 may be tilted inward, but a three-dimensional gather 30 such as C-folding or Z-folding that is turned over or part of the three-dimensional gather 30 may be arranged. There is no need for a pair when arranging, and a plurality of sets of solid gathers may be arranged by appropriately combining them. Moreover, although the elastic member 31 which comprises the three-dimensional gather 30 may be one, multiple pieces may be arrange | positioned. Although the base end part of the three-dimensional gathers 30 may be installed outside the absorber 15, it may be on the absorber 15 or an elastic member around the leg, and is not particularly limited.

  The height of the three-dimensional gather is 5 mm or more and 100 mm or less. If the excrement stays on the absorbent pad 11 below 5 mm, it cannot be a sufficiently high weir. Conversely, if it exceeds 100 mm, the upper surface of the absorbent pad 11 is covered by the crotch portion 12C, which may cause leakage, or the three-dimensional gather 30 extends to the outside of the absorbent pad 11 and urine to the outside, etc. It becomes a flow path and may cause leakage.

  The absorber 15 does not need to be an hourglass shape, and may be a rectangle or a T-shape. When the absorbent pad 11 is disposed only from the front body part 12F of the pant body 12 to the crotch part 12C, in order to improve the fit at the crotch part 12C, it is preferably T-shaped, It is not limited.

  As illustrated, the absorbent pad 11 may have the same width at both ends in the longitudinal direction, or may be different. When arrange | positioning only in a urination position or a defecation position, the width | variety of the edge part which hits the front body part 12F or the back body part 12R may be formed wider than the width | variety of the edge part which hits the crotch part 12C. Further, in the case of the absorbent pad 11 arranged only at the urination position or the defecation position, the leg elastic member is moved to one longitudinal end edge side of the absorbent pad 11 so as to coincide with the leg opening 12L of the pant body 12. You may arrange in the form.

  FIG. 28 shows a cross-sectional structure of another embodiment of the absorbent pad 11, and an absorption wrapped with a diffusion sheet 32 and tissue 33 between a liquid-permeable top sheet 13 and a liquid-impermeable back sheet 14. The body 15 is disposed, and cover sheets 28 are disposed on both sides of the absorbent body 15. The cover sheet 28 may be hydrophilic, but is preferably water repellent. In this embodiment, the cover sheets 28 are disposed on both sides of the top sheet 13 in the width direction. However, the cover sheets 28 may be omitted and the whole may be covered with the liquid permeable top sheet 13.

  FIG. 29 shows the developed shape of the embodiment in which the cover sheet 36 is disposed separately from the pant body 12. In FIG. 29, a cover sheet 36 having an opening 35 is arranged on the outer surface defecation side of the pant body 12 having a front opening 25 and a rear opening 26, and two absorbent pads 11 are arranged on the outer side. ing. The cover sheet 36 is joined to the pant body 12 so that the opening 35 of the cover sheet 36 matches the rear opening 26 of the pant body 12. By this arrangement, excretion excreted through the openings 25 and 26 of the pant body 12 spreads on the surface of the absorbent pad 11, and the absorbent pad 11 is pressed against the pant body 12 by the posture of the wearer. Since the outer side of the pant body 12 is covered with the cover sheet 36, the outer side of the pant body 12 can be used without being stained.

  The cover sheet 36 is partly or entirely joined to the outside of the pant body 12 by a known joining means such as an adhesive or mechanical joining. The cover sheet 36 only needs to have a size that does not contaminate the pant body 12, and the size is not particularly limited, but is preferably larger than the overlapping portion of the absorbent pad 11 with the pant body 12. When the cover sheet 36 is disposed, the absorbent pad 11 may be structured to be bonded to the cover sheet 36 bonded to the pant body 12.

  The opening 35 formed in the cover sheet 36 may be the same size as the rear opening 26 of the pant body 12 or may be different. The rear opening 26 of the pant body 12 is preferably larger than the opening 35 of the cover sheet 36. In this case, the pant body 12 can be used without making it dirty. Further, an elastic member may be disposed around the opening 35.

  The cover sheet 36 may be a hydrophilic material used for the top sheet 13 of the absorbent pad 11, but is preferably a water-repellent or liquid-impermeable material.

  In the present embodiment, the cover sheet 36 is disposed only on the defecation side, but can also be disposed on the urination side. In this case, one cover sheet 36 having two openings 35 may be arranged, but two cover sheets 36 each having one opening 35 may be arranged. . When separate cover sheets 36 are arranged on the urination side and the defecation side, it is economical because only the dirty cover sheet 36 can be replaced when only one of them is dirty.

  Furthermore, although the present Example has shown the case where the underpants main body 12 and the two absorption pads 11 which have the two opening parts 25 and 26 are arrange | positioned, the number of the absorption pads 11, a magnitude | size, and an arrangement position are not specifically limited.
