Description

  The present invention relates to an absorbent article, and more particularly to an absorbent article for adult men.

  Absorbent articles include pants-type and tape-type disposable paper diapers, which are widely used as sanitary products for infants and care recipients who are difficult to excrete by themselves. And since an absorbent article makes it a main function to absorb and hold | maintain excrement reliably, the opening part which takes in and out a genital like the underwear for men is not normally provided.

On the other hand, when used as an auxiliary device for mild incontinence, urination may be performed by oneself depending on the symptoms and condition of the wearer. Even such a male wearer must lower the diaper and cannot easily urinate by taking out the genitals. Every time you urinate, you need to take down your diaper, etc., and you will always have to enter a private toilet, which may be inconvenient for male wearers. In addition, such inconvenience and resistance may make painful rehabilitation of male patients and incontinence patients in the early stages of urination disorder.
Instead of shifting the diaper, it may be possible to urinate by cleaving the side seal or the like, but after all, it takes time and effort as well as shifting the diaper. In addition, since the diaper cannot be reattached every time urination, it must be replaced with a new one, which is not only inconvenient but also extremely uneconomical. It is desired to maintain the liquid absorbency / retainability, which is the original function of the absorbent article, and to eliminate the above inconveniences.

  On the other hand, an inner sheet provided on the surface side in contact with the human body, an outer sheet provided on the opposite side to the surface in contact with the human body, and an intermediate sheet provided between the inner sheet and the outer sheet. A disposable diaper cover that is divided into an abdominal side portion located on the abdomen side of the wearer when worn, a dorsal side portion located on the dorsal side, and a crotch portion between the abdominal side portion and the dorsal side portion The inner sheet and the outer sheet on the abdominal side are provided with an opening having a size that allows a male genital to be taken out when worn, or a perforation or region for forming the opening. By shifting the sheet, the openings of the inner sheet and the outer sheet communicate with each other so that a through-hole can be formed in the ventral side, and the inner sheet and the opening of the outer sheet are formed by the intermediate sheet. When covering That the intermediate sheet to said inner sheet or the outer sheet is secured and peeling freely fastening member is provided it is disclosed (see Patent Document). However, the one disclosed here is provided with perforations above the absorber, and eventually it is necessary to shift the diaper for urination.

  The present invention is an absorbent article having an outer sheet and an absorbent body partially bonded and fixed to the inner side of the outer sheet, and an opening capable of breaking and opening the outer sheet in a region of the outer sheet where the absorbent body is disposed An outer part is provided, and the outer sheet and the absorbent body are brought into a non-adhesive state around the openable part, and the openable part is broken open to float the non-adhesive part of the absorbent body and take out the male genitalia The above objectives have been achieved with the absorbent article made to be moist.

  The absorbent article of the present invention has an excellent effect that it is easy to take out male genitalia without having to shift the absorbent article when the wearer urinates while maintaining good liquid absorbency and retention. . In addition, the absorbent article of the present invention maintains the above-mentioned excellent functions and should be suitably used for patients with mild incontinence, patients who need rehabilitation for urination, and those who require severe care requiring difficulty in detaching with the waist lifted. In particular, the mental burden of urination for male wearers can be reduced.

Hereinafter, the absorbent article of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view schematically showing a pants-type disposable diaper as a preferred embodiment of the absorbent article of the present invention in a substantially mounted state. Hereinafter, although a preferable aspect is demonstrated based on the diaper 10 of this embodiment, this invention is limited to this and is not interpreted.
In the diaper 10 of the present embodiment, a waist opening 11 and a pair of left and right leg openings 12 are provided. A plurality of elastic members 9 forming waist gathers are disposed in the vicinity of the waist opening 11 so that the waist is properly tightened to fit. Further, a plurality of elastic members 8 forming leg gathers are also provided in the vicinity of the leg opening 12, and a good fit is realized by appropriately tightening the thigh.

  In the diaper 10 of this embodiment, the side seal part 5 is provided and the side part is joined, but in addition to this form, a tape-type diaper may be provided without providing the side seal part 5. Moreover, although the diaper 10 of this embodiment is illustrated as a diaper for adults, a diaper for infants may be sufficient and it can be set as the absorbent article made into the form required according to needs. However, as will be described later, the absorbent article of the present invention has the advantage of facilitating the removal of male genitalia, so it is preferably used as a male absorbent article or a male-female absorbent article.

  In the diaper 10 of this embodiment, the perforation 1 as an openable part is provided in the outer packaging sheet 3 on the diaper belly side f. The position where the perforation 1 is provided is a region where the absorbent body 6 provided on the article side is disposed. At this time, as shown in the figure, the abdominal side where the wearer's genitals can be easily taken out, more specifically, the center of the lower abdomen and The vicinity is preferable. In this way, the wearing state during normal use is such that the absorbent body 6 is appropriately positioned in the excretion region as shown in FIG. 1 to achieve good liquid absorption retention, and the genitals are accurately obtained during urination. Can be taken out.

  In the present invention, the openable portion is not limited to the perforation 1 as illustrated, and may be a honeycomb-shaped perforated row in which slits and perforations that can be opened are provided densely. In particular, it is preferable that the openable portion is the perforation 1 in consideration of workability, ease of opening, and the like. In the illustrated example, the perforation 1 is provided with its longitudinal direction oriented in the height direction (Y direction), but may be provided in the width direction (X direction), or in other oblique directions. Good. In addition, the perforations that are not limited to straight perforations, such as those shown in the figure, but perforations that intersect the cross, or perforations that are bent at the “U” or “U”, are appropriate depending on the function. Can be perforated in the form.

  When the openable portion is perforated, the length of one linear perforated portion is not particularly limited, but considering the dimensions of an adult diaper, it is practical to be about 3 to 8 mm. The interval between them (the length of the continuous portion) is practically about 1 to 5 mm. The length of the perforation 1 as a whole is not particularly limited, but is preferably about 50 to 200 mm in consideration of the dimensions of an adult diaper.

  It is preferable that the perforation 1 as the openable portion is arranged so as to be shifted somewhat to the left or right with respect to the midline p as in the diaper 10 of the present embodiment (in the present invention, the midline is the wearer's Assuming a midline that divides the body into a left and right body, this is the line formed by the crossing of the midline and a worn diaper.) In this way, it is preferable to slightly shift to the left or right of the median line p, so that when the male genitalia is taken out, an operation of floating the absorber described later is facilitated.

  It is preferable that an elastic member for forming a mouth opening prevention gather is provided at the upper part and / or the lower part of the openable part. In the diaper 10 of this embodiment, the elastic member forming the mouth opening prevention gather at the upper part of the perforation 1. 2 is provided. The elastic member 2 is preferably disposed so as to expand and contract in the article width direction (X direction) as illustrated. By doing so, even after the perforation 1 is once cut and opened, the opening state of the opening is prevented and is preferable for continuous use.

  FIG. 2 is an enlarged perspective view schematically showing a state when the perforation 1 of the diaper of the embodiment shown in FIG. 1 is divided and opened. The dividing opening mode of the perforation 1 is not limited to the mode shown in FIG. 2, but if the perforation is oriented in the length direction (Y direction) like the diaper 10 of the present embodiment, Normally, the fingers 22 and 23 of the left and right hands of the wearer, specifically, the both sides of the perforation 1 can be grasped by the respective thumbs and forefinger, and separated and opened in the direction of the arrow 24. . By doing so, the wearer himself can easily divide and open the openable part without preparing the caregiver or the like, and can prepare to take out the genitals and urinate. The absorbent body 6 inside the outer sheet 3 is exposed from the opening 21 thus created. The absorbent body 6 can be deformed so as to float when viewed from the outer packaging sheet 3, that is, pushed into the wearer's skin from the illustrated opening 21, and the male genitalia can be taken out.

  In the vicinity of the openable portion, as a rejoining means, for example, a seal portion coated with an adhesive tape or an adhesive may be provided. By doing so, for example, even after the perforation 1 is once cut and opened, it can be rejoined by the joining means and the outer sheet can be returned to a continuous state. However, in consideration of the work of the wearer to be rejoined, the production efficiency and cost of the article, it is practical to deal with the elastic member 2 having the above-described gather preventive gather without providing rejoining means or the like. It is preferable.

  FIG. 3 is a plan development view schematically showing a state where the diaper of the embodiment shown in FIG. 1 is expanded and developed. As already described, in the diaper 10 of this embodiment, the absorber 6 is provided inside the outer sheet 3, and a plurality of elastic members 9 forming a waist gather are provided in the vicinity of the waist opening. (However, the elastic member 8 forming the leg gathers and the elastic member 2 forming the mouth opening prevention gathers (see FIG. 1) are not shown). In the diaper 10 of the present embodiment, the outer sheet 3 is distributed more widely on the back side r than on the ventral side f. By doing in this way, when it wears so that crotch line c may be arranged between a wearer's crotch, it will become a form which wraps an overhanging heel part appropriately than usual, and is preferred.

  In the absorbent article of the present invention, the absorbent body 6 is long like the one shown in FIG. 3 and is long on the inner side of the outer packaging sheet 3 so as to extend from the wearer's abdominal side f to the back side r. It is preferable to arrange a long-sized absorber 6. Here, regarding the adhesive fixing mode between the outer sheet 3 and the absorbent body 6, the following three types can be distinguished from each other.

  As a preferred mode 1 of adhesive fixing, there is a mode in which the outer sheet 3 and the absorbent body 6 are bonded and fixed only in the vicinity of both end portions in the longitudinal direction of the absorbent body 6. In the embodiment shown in FIG. 3, the fixing mode is such that only the adhesive fixing portions 6a and 6d are adhesively fixed. A wide central region of the absorbent body 6 other than the adhesively fixed part is not fixed, and the absorbent body 6 is clamped between the outer packaging sheet 3 and the wearer's skin by wearing, including the periphery of the crotch line c, and the absorbent body 6 is fixed in position. It will be in the state.

  As another preferable aspect 2 of the adhesive fixing, there is an aspect in which the outer sheet 3 and the long absorbent body 6 are adhesively fixed only in the substantially entire region on the back side r of the absorbent body 6 and in the vicinity of the end portion on the ventral side f. . In the embodiment shown in FIG. 3, the fixing state is such that the adhesive fixing portions 6 a, 6 b and 6 d and the adhesive fixing portion 6 c are adhesively fixed only at the back side portion. At this time, the back side portions of the mounting fixing portions 6a, 6b, and 6c may be divided into a single mounting fixing portion. Thereby, when it says in the form of FIG. 3, the non-adhesion state is implement | achieved over the article | item width direction (X direction) in the ventral | abdominal part of the absorber 6 which provided the perforation 1. FIG. In this way, for example, in the form shown in FIG. 3, the perforation 1 is provided on the right side of the midline p, but the perforation (not shown) is also provided on the left side of the midline p at the same time. be able to. Accordingly, it is possible to determine whether to use the right perforation 1 or the left perforation (not shown) according to the wearer's preference, which is preferable in that the number of options increases. In this way, when the perforation is provided on both the left and right sides, in the illustrated form, the fold line 6f of the absorber described later is provided only on the right side, but it is preferable to provide the fold line (not shown) on the left side. .

  As still another preferable aspect 3 of the adhesive fixing, the outer sheet 3 and the long absorbent body 6 are added to the adhesive fixing part of the above aspect 2, and either left or right with respect to the midline on the ventral side f of the absorbent body 6 The mode which adhere | attaches and fixes is mentioned. At this time, it is preferable that the perforation is arranged so as to be shifted in the left-right reverse direction of the median line with respect to the adhesive fixing portion so as to avoid the adhesively fixed portion of the absorber. In the embodiment shown in FIG. 3, the adhesive fixing portions 6a, 6b, 6c, and 6d are bonded and fixed. At this time, the adhesive fixing portions 6a, 6b, 6c, and 6d may be divided into one continuous adhesive fixing portion without being divided. In this adhesive fixing mode, the left side of the median line p is fixed by the adhesive fixing part 6c on the ventral side f of the absorbent body 6, and the perforation 1 is provided on the opposite right side. However, the perforation 1 and the adhesive fixing portion 6c may be arranged in the opposite directions.

  A method for adhering and fixing the absorbent body 6 and the outer sheet 3 may be an ordinary method, for example, hot melt adhesion.

In the absorbent article of the present invention, it is preferable to provide a crease in the absorbent body. In the diaper 10 of this embodiment, a crease line 6f bent in a “V shape” is provided so as to cross the upper part of the linear perforation 1 twice. By doing in this way, it becomes easy to float the absorber 6 along the crease line 6f, and the male genitalia can be taken out accurately.
FIG. 4 is an enlarged sectional view showing a section taken along line IV-IV in FIG. In the same figure, the part which provided the folding line of the diaper 10 of this embodiment is shown as sectional drawing. In the present embodiment, the outer sheet 3 is made of a two-layer sheet material of an inner sheet 3a and an outer sheet 3b, but the number and form of the outer sheet 3 are not particularly limited, and it is considered that sufficient strength is obtained. A two-layer sheet as described above is preferable.

  In the cross-sectional position of the diaper shown in FIG. 4, the absorbent body 6 and the outer sheet 3 (inner sheet 3a) are bonded and fixed in the left region q of the midline p, and are not bonded in the other regions r. Yes. And it turns out that the folding line 6f is provided in the upper part vicinity of the perforation 1 of an absorber. Although the cross-sectional shape of the folding line 6f of the absorber 6 is not particularly limited, for example, a constricted shape obtained by compressing the absorber as shown in FIG. Such a compression constriction shape can be formed by consolidating the absorbent body by a normal thermocompression bonding process. Thereby, the part 6e of the absorber is in a state of being easily deformed (hereinafter, the part 6e that has been easily deformed by the folding fold is referred to as a deformable part).

  FIG. 5 is an enlarged development plan view schematically showing an aspect in which the perforation is divided and opened in the diaper of the present embodiment to float the absorber. FIG. 6 is an enlarged sectional view showing a section taken along line VI-VI in FIG. As shown in both figures, the diaper of this embodiment can insert the finger 52 etc. from the opening part 21 which opened the perforation 1, and can float the deformable part 6e of the absorber 6. FIG.

  As described above, in the present embodiment, since the arbitrary folding line 6f is provided at an effective position, the deformable portion 6e of the absorber is accurately floated, and the space inside the article and the external space can be made continuous. . Further, in the present embodiment, a V-shaped crease line (see FIG. 5) and a compression-creased crease line with a constricted cross section (see FIG. 6) are provided, so that the deformable portion 6e can be easily floated and returned. As described above, the deformable portion 6e of the absorbent body can be easily deformed and returned to the original shape, so that the male genitalia can be reliably and quickly inserted even in the gap between the crotch and the absorbent article with little gap in the mounted state. Can be taken out and stored again. Furthermore, even if the central part of the absorbent body 6 is slightly wetted and swollen due to incontinence or urine leakage, the deformable part 6e is almost unaffected and deforms easily and appropriately. be able to.

  In the absorbent article of the present invention, as shown in its preferred embodiment, the wearer's confidence can open the male part and urinate by separating and opening the opening. Therefore, it is preferably used for patients with mild incontinence or during rehabilitation. Furthermore, even male patients who are difficult to move, such as lifting their waists, who had to give up urinating on their own, can take out male genitals themselves and urinate, which contributes to reducing the mental burden It is. It can also be used as a training diaper for infants.

As described above, the outer sheet 3 can have a two-layer structure including the inner sheet 3a and the outer sheet 3b. At that time, the material of both sheets is not particularly limited, and a material normally used for absorbent articles can be used. it can. For example, in a two-layered sheet composed of an inner sheet 3a and an outer sheet 3b that constitute the outer package sheet 3, it is preferable that both are composed of a water-repellent nonwoven fabric. Further, it is also preferable to form a sheet having a three-layer structure with a vapor permeable sheet provided with vapor permeability, for example, from the viewpoint of preventing stuffiness, while being liquid-impermeable between the two sheets.
For the inner sheet 3a and the outer sheet 3b, it is preferable to use a liquid-impermeable sheet in view of the liquid leakage prevention property. For example, a waterproof sheet material such as polyethylene can be used, from the viewpoint of preventing stuffiness. Further, a sheet material having moisture permeability is preferable. As a sheet material having this waterproofness and moisture permeability, for example, a sheet is formed by melting and kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene, and then stretched in a uniaxial or biaxial direction. The microporous sheet material obtained by is preferably used.

  The absorbent body 6 is not particularly limited as long as it has a function of absorbing liquid. For example, the absorbent body 6 is made of a superabsorbent polymer such as a superabsorbent polymer, a superabsorbent fiber, pulp, or the like, and is made of a single material made of these materials. A layer structure may be sufficient and the structure divided into several layers may be sufficient.

  As materials for the elastic members 2, 9, and 8, elastic materials that are normally used for absorbent articles can be used. For example, synthetic rubber such as styrene-butadiene, butadiene, isoprene, and neoprene, natural rubber, EVA, and stretchability. Examples thereof include polyolefin and polyurethane. As the cross-sectional shape of the elastic member, a thread shape or string shape (flat rubber or the like) such as a rectangle, a square, a circle, or a polygon, or a multifilament type thread shape can be used.
