Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an absorbent article that is intended to reduce the skin trouble of the buttock in consideration of preventing stool from directly adhering to the wearer's buttock, and in particular, so that only the stool can be taken out from the absorbent article and easily discarded. It is a thing. The “absorbent article” in the present invention represents an infant or a nursing diaper, an adult incontinence product, and the like.
[0002]
[Prior art]
According to “so-called diaper rash” by Kazuya Yamamoto described on page 949 to page 956 (1998) of dermatology 30 regarding the cause and pathogenesis of diaper rash, (1) urine and feces are mixed. Ammonia is generated, (2) this ammonia makes the environment alkaline, (3) the enzyme in the stool is strongly activated in an alkaline atmosphere, (4) the weakened part of the skin is inflamed by this enzyme and ammonia, and the diaper It states that a rash will occur. Causes of weakened skin are the mechanical irritation such as the touch of the diaper components that come into contact with the skin, and the environment inside the diaper where the skin becomes soft due to high humidity in the diaper. It has been pointed out.
[0003]
Even if there is defecation by improving the performance accompanying the technological advancement of the water-absorbing polymer material, for example, by quickly absorbing this after urination and reducing its osmotic diffusion against the cause of diaper rash as described above It is possible to make it difficult to mix with this. As for the environment inside the diaper, for example, by using a breathable sheet for the diaper, it is possible to take measures against stuffiness in the diaper and to prevent the skin from being softened. Since countermeasures against diaper rash have progressed in this way, skin troubles such as rash caused by the use of so-called disposable diapers have also decreased.
[0004]
However, when urine and feces are excreted almost simultaneously, or for prevention of rashes on soft stools, measures have not been sufficient. In the case of loose stool, if it is left unmixed with urine, the burden on the skin increases. Since loose stool hardly passes through the top sheet of the diaper that comes into contact with the skin, a part of the moisture remains on the top sheet and adheres to the wearer's buttocks, except for a part of the moisture transferred to the absorber. For this reason, even if trouble does not occur in the skin, the wiping work on the buttocks becomes complicated when changing diapers.
[0005]
In this way, in order to prevent stool and urine from mixing with each other and stool from adhering to the buttocks, for example, an opening for dropping stool into the top sheet or skin contact sheet of a diaper is provided, and urine and stool are collected. Diapers with a structure that can be separated have been proposed. However, since the top sheet and the skin contact sheet itself do not have a function of maintaining the shape of the diaper when worn, it is difficult to maintain the opening in a released state.
[0006]
From this point of view, in Japanese Patent Application Laid-Open No. 61-41304, Utility Model Registration No. 2559050, Special Table No. 10-513072, Japanese Utility Model Application Publication No. 6-5614, Japanese Utility Model Application Publication No. 6-11723, etc. Diapers that can separate feces have been proposed.
[0007]
The diaper disclosed in Japanese Patent Application Laid-Open No. 61-41304 has a so-called top sheet by providing a long opening in the length direction at the center of the top sheet and attaching an elastic member along the peripheral edge of the opening. It is designed so that the opening is not blocked by having a stiffness. The disposable diaper disclosed in Utility Model Registration No. 2559050 has a liquid-absorbing panel interposed between a liquid-permeable inner sheet and a liquid-impervious outer sheet, and a wearer on the upper surface of the liquid-permeable inner sheet. The second liquid-permeable inner sheet provided with an opening facing the urinary organ and anus is overlapped, and a gap is formed between these two inner sheets. Moreover, the disposable absorbent article disclosed in Japanese Patent Publication No. 10-513072 is provided with a hole facing the wearer's anus and / or urethra opening, and absorbability for receiving feces and / or urine through the hole. A pocket in which a material is arranged is formed. The diaper disclosed in Japanese Utility Model Laid-Open No. 6-5614 includes a recess extending under an opening provided in the surface sheet, and a valve portion having the surface sheet extending from the periphery of the opening to the center. In order to prevent the stool separated by the opening from returning. Further, in the diaper disclosed in Japanese Utility Model Laid-Open No. 6-11723, the second surface sheet is overlapped with the first surface sheet, and the opening formed in the central region in the length direction of the second surface sheet is formed in the lateral direction. A plurality of elastic members are arranged to be expanded.
[0008]
[Problems to be solved by the invention]
In the case of a diaper disclosed in Japanese Patent Application Laid-Open No. 61-41304 and Japanese Utility Model Laid-Open No. 6-5614, when the diaper is actually worn, the crotch portion of the diaper is located on the center side by the crotch of the wearer's legs. It became clear that it was in a state where it hanged down without being in close contact with the skin. That is, since the crotch part of the top sheet or the top sheet (hereinafter collectively referred to as the top sheet) is not in close contact with the wearer's crotch, the opening provided in the top sheet does not make sense for these diapers. This causes a problem that the stool spreads on the top sheet. Even if the position of the opening of the top sheet matches the position of the wearer's anus, since the top sheet is not in close contact with the wearer's crotch, the opening is closed, and the opening is closed. It is expected that the stool cannot be guided between the top sheet and the back sheet.
[0009]
The diaper disclosed in Japanese Utility Model Publication No. Hei 6-11723 has a similar problem, the opening is only expanded in the width direction, and the opening is crushed depending on the wearing state, and the opening Basically, it is impossible to make full use of these functions.
[0010]
Further, in the case of the disposable diaper disclosed in Utility Model Registration No. 2559050, urine and feces are less likely to adhere to the buttocks, but it is not possible to prevent urine and stool from being mixed together. Can not eliminate the pollution.
[0011]
Further, when the stool is treated with the disposable absorbent article disclosed in JP-T-10-513072, it is necessary to discard the entire disposable absorbent article. If the urine is not excreted, the urine is absorbed. It will be discarded without effectively using the function. Such a problem applies to all of the conventional diapers described above.
[0012]

DETAILED DESCRIPTION OF THE INVENTION
As the back sheet in the present invention, a liquid-impermeable polyethylene sheet is preferably used, and more preferably has moisture permeability such as a polyethylene sheet provided with micropores or a sheet obtained by adding a filler to a thermoplastic resin. By using the soaked one, it is possible to reduce the stuffiness and make it comfortable. Furthermore, a non-woven fabric may be attached to form the back sheet in order to improve the feel on the outside of the sheet and reduce the unique rubbing sound of the synthetic resin sheet. As this non-woven fabric, synthetic fibers made from thermoplastic resins such as polyethylene, polypropylene, and polyester can be employed, and any of liquid impermeability and liquid permeation may be used.
[0028]
As the liquid-permeable top sheet in the present invention, a non-woven fabric, a perforated non-woven fabric, a mesh sheet, or the like made of synthetic fiber made of polyethylene, polypropylene, polyester, or other thermoplastic resin is used.
[0029]
The stool separation sheet in the present invention has an opening structure that allows stool to pass through the stool separation sheet, and the opening ratio can be arbitrarily set within a range of 10 to 90%. If the open area ratio is less than 10%, it is difficult to pass the stool. Conversely, if it exceeds 90%, the stool passes reversely and the buttock is easily soiled. As the form of the opening of the stool separation sheet, for example, a notch, a mesh, or a mesh can be adopted. More specifically, a non-woven fabric made of polyethylene, polypropylene, polyester, or other synthetic fiber made of thermoplastic resin is used as a notch, or a non-woven fabric with holes formed by a hot needle or suction treatment. can do. In addition, a mesh sheet, a mesh sheet, a perforated film, a perforated sheet made from a foamed resin, or a mesh sheet may be used. As a stool separation sheet using foamed resin, a foamed resin sheet obtained by adding a foaming agent to polyethylene, polypropylene, or polystyrene and extruding the sheet into a sheet shape. A net obtained by extruding a resin sheet in a mesh shape can be used.
[0030]
The above-mentioned mesh-like sheet is well known as a buffer material for transporting fruits. For example, Miranet (trade name: manufactured by JSP Co., Ltd.) made of foamed polyethylene by a non-crosslinking method is commercially available and wraps the heel part. Since it has a characteristic that it can be easily deformed, it is suitable as a constituent material of the feces separation sheet in the present invention.
[0031]
Commercially available foamed resin sheets include polyethylene foam as a raw material, such as Miramat (trade name: manufactured by JSP Corporation), Hiethylene S (trade name: manufactured by Hitachi Chemical Co., Ltd.), Softlon. (Trade name: manufactured by Sekisui Chemical Co., Ltd.), foamed polypropylene sheet made of polypropylene, for example, high ethylene PP (trade name: manufactured by Hitachi Chemical Co., Ltd.), peamat (trade name: manufactured by JSP Corporation), or Examples thereof include expanded polystyrene sheets made of polystyrene as a raw material, such as post-styrene paper (trade name: manufactured by JSP Corporation), Miraboard (trade name: manufactured by JSP Corporation), and the like. Among these, Miramat is suitable as a constituent material of the stool separation sheet in the present invention because it is flexible and not crosslinked.
[0032]
In order to form a gap between the stool separation sheet and the second absorbent body, the stool separation sheet itself has elasticity, or the joining portion of the back sheet to which the stool separation sheet is joined has elasticity. There is a way. When the stool separation sheet is provided with elastic elasticity, the contraction force of the stool separation sheet is utilized by joining the both ends to the back sheet side in a stretched state along the longitudinal direction of the stool separation sheet. This is brought into close contact with the wearer's skin. In this case, the side edge portion of the stool separation sheet is also joined to the back sheet, so that a bag-like gap is formed between the back sheet and the stool separation sheet. In addition, in the case where the joining portion of the back sheet to which the stool separation sheet is joined has stretch elasticity, the stool separation sheet and the back sheet are joined via the stretch elastic sheet, and the stretch elastic sheet is stretched. The stool separation sheet is brought into close contact with the wearer's skin, and a gap is formed between the stool separation sheet and the second absorbent body held on the back sheet.
[0033]
In the present invention, the first absorbent body is preferably one in which wood pulp or fluff pulp made of non-wood pulp in cotton form is used as a main material and a water absorbent polymer material (SAP) in combination. Mixtures and laminates such as heat-sealing fibers are used. Further, a laminated structure in which the whole is wrapped with tissue to prevent SAP from popping out may be used. Specifically, a coating solution in which SAP and microfibril cellulose are dispersed in a mixed solution of propylene glycol or methanol and water is directly applied to the top sheet, or polyethylene, polypropylene, polyester, and other thermoplastic resins are used as raw materials. A sheet having SAP as a main component applied to a non-woven fabric made of synthetic fibers is used.
[0034]
When the first absorbent body has a structure in which a liquid-impermeable sheet is laminated on the surface in contact with the back sheet, a liquid-permeable material can be used as the back sheet, and air permeability is improved. Steaming can be prevented.
[0035]
Furthermore, an adhesive tape, a hook-and-loop fastener, or the like may be attached to the contact surface of the back sheet with the first absorbent body so that the first absorbent body can be detachably fixed to the back sheet.
[0036]
As the second absorber in the present invention, a hydrolytic paper sheet using rayon, pulp, CMC-Ca or the like is used for the surface layer, fluff pulp, curly fiber or the like is used for the absorbent core, and PVA is laminated to the back layer for the tissue. What used the poorly water-permeable sheet | seat etc. can be employ | adopted. In this case, what used SAP together with the fluff pulp which made wood pulp and the non-wood pulp into cotton shape as an absorption core is preferable. By making the SAP 10% by weight or less, the second absorbent body itself can be made water-degradable.
[0037]
As the gripping portion provided on the second absorbent body in the present invention, water-degradable materials that are usually used, such as paper, PVA film, and composites thereof, can be used. It is preferably in the form of a string or tape.
[0038]
As for the partition member of this invention, the longitudinal direction one end part is joined to a back sheet | seat in a crotch part, and the other end part is joined to a top sheet or a feces separation sheet | seat. In order to further ensure separation of urine and stool, two of the partition members are arranged, one end in the longitudinal direction is joined to the back sheet at the crotch, and the other end is joined to the top sheet. At the same time, the other end may be joined to the stool separation sheet. As this partition member, a film or a nonwoven fabric made of a thermoplastic resin such as polyethylene, polypropylene, or polyester is used. When using a nonwoven fabric, the thing of the SMS structure and SMMS structure which compounded spunbond (S) and melt blow (M), for example is suitable.
[0039]
In the present invention, it is effective to form a take-out port for taking out the second absorbent body in the back sheet or the feces separation sheet. The position of the take-out port can be arbitrarily selected from the crotch part to the back body part, and any form can be used as long as the second absorbent body can be taken out therefrom. For example, a perforation may be provided in the back sheet or the stool separation sheet, and when the second absorbent body is taken out, the perforation may be broken to form a take-out port. Alternatively, it is also effective to form a notch that can be opened and closed in advance as an extraction port, and attach an adhesive tape, a zipper, a hook-and-loop fastener, etc. to prevent the extraction port from opening when it is unnecessary. When the take-out port is not provided, the second absorbent body of the back sheet can be taken out by adopting a configuration in which the feces separation sheet can be peeled from the back sheet.
[0040]
Furthermore, in the absorbent article of the present invention, a takeout port for taking out the first absorbent body can be formed in the backsheet or topsheet. The position and form of the takeout port may be the same as in the case of the takeout port formed in the back sheet or the feces separation sheet in order to take out the second absorbent body as described above.
[0041]
Further, in the absorbent article of the present invention, when a material made of cloth is used as a material for parts other than the first and second absorbents, and the body part of the absorbent article is formed by sewing this, the absorbent body Only the discarded body part can be washed and reused.
[0042]
