Description

  The present invention relates to an absorbent article and a method for producing the same. More specifically, the present invention relates to an absorbent article that can be disposed inside clothing or a diaper so that excrement can be well absorbed and retained, and a method for manufacturing the same.

  Conventionally, as an absorbent article for infants or adults such as the elderly and disabled persons, a urine pad provided with a top sheet, a back sheet, and an absorbent body interposed between a part of both sheets, A stool pad is used.

  The above-mentioned urine pad is used so that the surface of the top sheet is in contact with the wearer's skin, so that the urine excreted by the wearer permeates the top sheet and is absorbed and held by the absorber. At the same time, leakage of excrement to the outside is prevented by the back sheet having excellent leakage prevention.

  Moreover, the male urine pad of the type which encloses and uses a male genitalia is known as an absorbent article specialized for men (for example, refer patent document 1). This male urine pad is an absorbent article provided with a top sheet, a back sheet and an absorbent body, similar to conventional disposable diapers and urine pads. It is characterized in that it is encapsulated.

For example, the male urine pad 100 shown in FIG. 23 includes a top sheet 102, a back sheet 104, and an absorbent body 106 interposed in a part between both sheets, and further on the back sheet 104 side. An adhesive portion 108 for mounting is formed on the surface. Such a male urine pad 100 is addressed from the lower side of the male genitalia 118 so that the upper edge 110 thereof is on the near side (the body side of the wearer), and along the straight lines L ₁ and L ₂ , After the right edge 112 and the left edge 114 are folded back toward the center of the pad, the adhesive portion 108 is used in a state of being fixed to the surface sheet 102 on the left edge 114 side. By doing so, the male urine pad 100 has a cone shape (sack shape) with the upper end edge 110 side as an opening and the lower end edge 116 side as an apex, so that the male genital box 118 can be encapsulated. Reference numeral 138 denotes a pad stretchable material.

  Since the male urine pad as described above is used in a state where the male genitalia is encapsulated, compared with a disposable diaper, or a urine pad that is simply placed on clothing or a diaper, excrement and the skin of the wearer The contact area can be reduced. Therefore, there is an advantage that skin troubles caused by excrement can be reduced.

  For example, although illustration is abbreviate | omitted, it has an absorber arrange | positioned between a surface sheet and a back surface sheet, and a flap part is along an outer side (outer edge) of an absorber along a longitudinal direction (left-right direction). A male urine pad (see, for example, Patent Document 2) in which a cut portion (slit) is formed at a substantially central portion in the longitudinal direction of the flap portion, or a male urine pad (for example, preliminarily molded into a bag shape) , See Patent Document 3).

  Hereinafter, the best mode for carrying out the absorbent article of the present invention will be described in more detail with reference to the drawings for each example of a male urine pad and a urine / feces pad.

[2] Male urine pad:
First, the example at the time of using the absorbent article of this invention as a urine pad for men is demonstrated. As shown in FIGS. 1-3, the male urine pad 1a which is one embodiment of the absorbent article 1 of the present invention is disposed so as to cover the absorbent body 2 and the surface of the absorbent body 2, and at least A part of the top sheet 3 made of a liquid permeable material and a back sheet 4 made of a liquid impermeable material are arranged so as to cover the back surface of the absorbent body 2. And a skin sheet body 5 having an opening 11 into which a device can be inserted. This male urine pad 1a is used for inserting a male genital into the opening 11 of the skin sheet body 5 to absorb urine. Here, FIG. 1 is a plan view showing an embodiment of the absorbent article of the present invention, and FIG. 2 shows a cross section of the absorbent article shown in FIG. 1 cut along the line AA ′. FIG. 3 is a schematic cross-sectional view, and FIG. 3 is a schematic cross-sectional view showing a cross section obtained by cutting the absorbent article shown in FIG. 1 along the line BB ′.

  In the male urine pad 1a of the present embodiment, since the male genitalia is held by the opening 11 of the skin sheet body 5, the fixation effect on the male genital is high, and the urine pad misalignment or detachment that causes urine leakage is prevented. It can be effectively prevented. Moreover, since the skin surface sheet body 5 is in contact with most of the wearer's skin (that is, the portion other than the male genitals inserted into the opening 11 of the skin surface sheet body 5), the skin of the wearer and the top sheet 3 is separated. Thereby, a favorable wearing feeling can be obtained.

  For example, as shown in FIG. 4, the male urine pad of the present embodiment is inserted at a substantially central portion on the longitudinal side of the male urine pad 1a after inserting the male device 21 into the opening 11 of the skin sheet body 5. Fold it in half. By comprising in this way, the front-end | tip part of the male device 21 can be hold | gripped so that it may wrap with the male urine pad 1a, and a fixing effect can be heightened.

  As shown in FIG. 1, in the male urine pad 1 a of the present embodiment, an elastic material 12 (hereinafter referred to as “opening elastic material”) along a part of the inner periphery of the opening 11 of the skin sheet body 5. It is preferable that the By comprising in this way, the opening part 11 can be expanded-contracted according to the size of a wearer's male device 21 (refer FIG. 4), and the effect which fixes the male device 21 (refer FIG. 4) is improved further. be able to. Moreover, since a favorable fixing effect can be obtained regardless of the size of the wearer's male genitals, the male genitals can be used particularly suitably for the elderly and disabled persons who often atrophy. For example, a conventional male urine pad as shown in FIG. 23 folds a sheet-like pad into a cone shape (sack shape) and fixes it with an adhesive portion, and encloses the male genitalia. Since pubic hair and clothing may stick to the skin, it is extremely difficult to use.

  In addition, when such an opening elastic member 12 is provided, as shown in FIG. 4, the male urine pad 1a (absorbent article 1) is used by being folded in half at the central portion on the longitudinal side. Furthermore, the skin surface sheet body 5 expands and contracts, and a space is formed between the skin surface sheet body 5 and the top sheet 3. For this reason, when excretion is performed from the male genitalia 21 inserted into the opening 11, the wearer's urine can be temporarily stored in this space. For example, when the amount of urine excreted at a time is large But urine is hard to leak outside. In addition, the size of the opening 11 can be adjusted by extending the both ends in the longitudinal direction of the male urine pad 1a by arranging the opening elastic member 12, and the male genital 21 The tightening degree can be easily adjusted. Note that the male urine pad 1a of the present embodiment is folded in advance at a substantially central portion on the longitudinal side, and when used, both end portions of the male urine pad 1a are widened. It is preferably used after being stretched. Here, FIG. 4 is explanatory drawing which shows the wearing condition at the time of using the absorbent article shown in FIG. 1 as a male urine pad.

  In the male urine pad 1a of the present embodiment, the male urine pad 1a is folded in advance at a substantially central portion on the longitudinal side, and when used, both end portions of the male urine pad 1a are widened. It is preferably used after being stretched. By comprising in this way, the front-end | tip part of the male genitalia 21 can be hold | gripped favorably so that it may wrap with the male urine pad 1a, and a fixing effect can be heightened further.

  Moreover, in the male urine pad 1a of this embodiment, as shown in FIG.5 and FIG.6, the skin sheet | seat body 5 is the both-sides edge 31 (31a, 31b) of the back seat | sheet 4, and at least one of the longitudinal direction Are joined at end portions 32 (both end portions 32a and 32b in FIGS. 5 and 6), and a bag-like space 33 is formed between the skin sheet body 5 and the top sheet 3. It is preferable. By configuring in this way, urine is held in the bag-shaped space 33 described above, so that, for example, even when the amount of urine excreted at a time is large, urine does not leak to the outside. . Here, FIG. 5 is a plan view showing another embodiment of the absorbent article of the present invention, and FIG. 6 shows a cross section of the absorbent article shown in FIG. 5 cut along the line CC ′. It is a schematic sectional drawing. In addition, there is no restriction | limiting in particular about the method of joining the skin sheet body 5 and the back sheet 4, For example, the conventionally well-known joining method by heat | fever including a heat seal, an ultrasonic wave, etc. can be used suitably.

Moreover, as shown in FIGS. 1-3, in the male urine pad 1a of this embodiment, the skin sheet body 5 is the at least one side edge 31 (in FIGS. 1-3) of the back seat | sheet 4. both side edges 31a, 31b) from the Ru der those constructed by folding a portion extending integrally on the surface of the top sheet 3 to the side. For example, as shown in FIGS. 7 and 8, the side flaps 5 a and 5 b as skin surface precursors that are integrally extended from both side edges 31 a and 31 b of the back sheet 4 to the side thereof are formed on the surface of the top sheet 3. A skin sheet body 5 (see FIG. 1) formed by folding up and joining the overlapping portions of the side flaps 5a and 5b can be given. When the skin sheet body 5 is configured in this way, when the side flaps 5a and 5b are folded back on the surface of the top sheet 3, portions where the portions do not overlap each other are provided. The opening part 11 of the skin surface sheet | seat body 5 as shown in 1 is formed. Since the male urine pad 1a configured in this manner has a simple structure, it can be manufactured easily and at low cost. Moreover, since it can produce by applying the existing production line for producing the conventional tape type diaper etc., it is excellent also in terms of equipment cost. Here, FIG.7 and FIG.8 is a top view which shows the state which expand | deployed one Embodiment of the absorbent article of this invention.

  Moreover, as shown in FIGS. 1-3, in the male urine pad 1a of this embodiment, it is preferable that at least one pair of the three-dimensional gathers 13 (13a, 13b) is formed on the surface of the top sheet 3. By comprising in this way, the side leakage of the urine which the wearer excreted can be prevented effectively.

  As shown in FIGS. 9 and 10, at least a pair of solid gathers 14 (14 a, 14 b) may be formed on the surface of the skin sheet body 5 that faces the top sheet 3. Such a three-dimensional gather 14 can have a function as a check valve for the opening 11 of the skin sheet body 5, and can effectively prevent urine backflow from the opening 11. Such a three-dimensional gather 14 may be an inversion gather that tilts toward the inside of the opening 11, but the absorbent article 1 can effectively prevent backflow of urine from the opening 11. It is preferable that the outer gathers are inclined toward the outside (specifically, the outside of the opening portion of the opening 11). Here, FIG. 9 is a plan view showing another embodiment of the absorbent article of the present invention, and FIG. 10 shows a cross section of the absorbent article shown in FIG. 9 cut along the line DD ′. It is a schematic sectional drawing.

  Further, in the male urine pad of the present embodiment, as shown in FIG. 11, the skin sheet body 5 and the top sheet 3 are side edges 31 a and 31 b on the side of the longitudinal end 32 from the opening 11. It may be joined in a part between. In addition, the code | symbol 17 shows the junction part of a skin surface sheet body and a top sheet. Since the urine excreted by the wearer passes through the top sheet 3 and is absorbed and held by the absorbent body 2, if the skin sheet body 5 and the top sheet 3 are too far apart, the urine moves over the top sheet 3. It may become difficult to permeate, and as a result, the speed absorbed by the absorber 2 may be slow. By comprising in this way, urine can be absorbed favorably, ensuring the space which inserts the male device 21 (refer FIG. 4). In addition, there is no restriction | limiting in particular about the method of joining the skin sheet body 5 and the top sheet 3, For example, the conventionally well-known joining method by heat | fever including a heat seal, an ultrasonic wave, etc. can be used suitably. Here, FIG. 11 is a plan view showing another embodiment of the absorbent article of the present invention.

  In FIG. 11, the skin sheet body 5 and the top sheet 3 are joined in stripes in the longitudinal direction of the absorbent article 1 (the direction from the opening 11 to the end 32) to form a joint 17. However, it is not limited to this shape. For example, although not shown, the absorbent article may be joined in a stripe shape from one side edge to the other side edge, or may be joined in a dot shape with a predetermined interval. .

  Further, in the male urine pad of the present embodiment, as shown in FIG. 12, the elastic material 15 (hereinafter referred to as “the urine pad”) is disposed on at least one end 32 side in the longitudinal direction of the male urine pad 1a (absorbent article 1). It is preferable that an “end stretchable material” is sometimes disposed. By arranging the end stretchable material 15 in this way, at least one end 32 side in the longitudinal direction of the male urine pad 1a can be contracted, and the side on which the end stretchable material 15 is disposed, By being positioned on the wearer's crotch side, it is easier to fit the wearer's body and the wearing feeling can be further improved. Here, FIG. 12 is a plan view showing another embodiment of the absorbent article of the present invention.

The male urine pad 1a shown in FIGS. 1 to 3 has a skin sheet body 5 integrally extended from the back sheet 4 to the side thereof, on the surface of the top sheet 3 outside the side edge of the absorbent body 2. It is configured to be folded back. Furthermore, as shown in FIGS. 13 and 14, the male urine pad 1 a according to the present embodiment has a skin sheet body 5 that is integrally extended from the back sheet 4 to the side thereof, and has side edges of the absorbent body 2. together with a part of, Ru der those constructed by folding back onto the surface of the top sheet 3. With this configuration, a part of the folded absorbent body 2 serves as a leak-proof wall, and the lateral leakage of urine excreted by the wearer can be achieved without arranging the three-dimensional gather 13 as shown in FIG. Can be effectively prevented. Here, FIG. 13 is a plan view showing another embodiment of the absorbent article of the present invention, and FIG. 14 shows a cross section of the absorbent article shown in FIG. 13 cut along the line EE ′. It is a schematic sectional drawing.

[3] Urine pad:
Next, an example in which the absorbent article of the present invention is used as a urine / feces pad will be described. As shown in FIGS. 1 to 3, a urine / feces pad 1 b, which is another embodiment of the absorbent article 1 of the present invention, is arranged so as to cover the absorbent body 2 and the surface of the absorbent body 2. The top sheet 3 made of a liquid permeable material, the back sheet 4 made of a liquid impermeable material, and the top sheet 3 are arranged so as to cover the back surface of the absorbent body 2. And a skin surface sheet 5 on which an opening 11 that can be passed is formed. This urine / feces pad 1b is used in the vicinity of the crotch of clothing or a diaper and absorbs and holds the stool and urine of the wearer to prevent leakage to the outside of the clothing or diaper. be able to. The urine / feces pad 1b of the present embodiment is different from the male urine pad 1a of the embodiment of the present invention described so far only in the method of use, and the configuration of the pad itself is the same. is there.

  Conventional urine / feces pads are made of a rough material on the top sheet in order to form a space for storing stool by providing a dent in the absorber and to prevent diffusion of stool excreted by the wearer. However, in reality, most of the stool remains on the top sheet, and the stool adheres to the wearer's crotch and buttocks. For this reason, a troublesome wiping work is required at the time of wearing, and this causes an increase in childcare burden and care burden, and also causes a skin trouble for the wearer.

  In the urine / feces pad 1b of the present embodiment, the stool excreted by the wearer passes through the opening 11 and falls onto the top sheet 3 so that the feces and the wearer's skin are in direct contact with each other. Can be greatly reduced. In addition, since the skin sheet body 5 first comes into contact with the skin of the wearer, the top sheet 3 disposed at the lower part of the skin sheet body 5 is difficult to directly contact the wearer's skin. That is, the wearer's skin and the top sheet 3 are separated. Furthermore, a shielding layer called a skin surface sheet 5 is interposed between the top sheet 3 and the skin of the wearer. Therefore, even if the stool remains on the top sheet 3, it has the effect of greatly reducing the chance that the stool and the skin of the wearer are in direct contact. For this reason, it is difficult for stool to adhere to the wearer's crotch and buttocks, so that troubles such as wiping work can be reduced and skin troubles of the wearer can be effectively prevented. In particular, the urine / feces pad 1b according to the present embodiment can cope with any stool satisfactorily without using stool properties such as watery stool, mud stool, and solid stool.

  Of course, the urine / feces pad 1b of the present embodiment can not only hold the stool of the wearer on the top sheet 3, but also can absorb and hold the urine excreted by the wearer by the absorbent body 2. For example, by using a skin surface sheet body having a urine permeable region that can transmit urine, the urine excreted by the wearer is transmitted through the urine permeable region and the top sheet of the skin surface sheet body, and the absorbent body. Can be absorbed and retained. The urine absorbed and retained by the absorber is prevented from leaking to the outside by the back sheet having excellent leakage prevention properties.

  Such a urine permeable region may be separately formed with an opening through which urine can permeate the skin sheet body, or a part of the skin sheet body is formed of a liquid permeable material. It is good also considering the site | part formed by urine permeation | transmission area | region.

  In the urine / feces pad 1b of the present embodiment, it is preferable that the opening stretchable material 12 is disposed along a part of the inner periphery of the opening 11 of the skin sheet body 5. By configuring in this way, as shown in FIG. 15, the skin surface sheet 5 expands and contracts, so that a substantially central portion (specifically, on the longitudinal side of the urine / feces pad 1 b (absorbent article 1)) The portion where the opening 11 is formed) is folded in half, and the opening 11 is greatly expanded. For this reason, it becomes easy to let the feces pass through the opening 11. Moreover, since a space is formed between the skin sheet body 5 and the top sheet 3, a space for temporarily storing the wearer's stool can be formed. For example, the amount of stool excreted at a time Even when there are many, stool can be held well in this space. Here, FIG. 15 is a perspective view showing a state where the absorbent article shown in FIG. 1 is bent at a substantially central portion on the longitudinal side.

  Note that the urine / feces pad 1b according to the present embodiment is previously folded in half at a substantially central portion on the longitudinal side, and when used, both ends of the urine / feces pad 1b are widened. It is preferably used after being stretched. By comprising in this way, the space between the above-mentioned skin surface sheet | seat body 5 and the top sheet 3 can be formed favorably.

  Further, in the urine / feces pad 1b of the present embodiment, as shown in FIGS. 5 and 6, the skin sheet body 5 includes the side edges 31 (31a, 31b) of the back sheet 4 and at least one of its longitudinal directions. Are joined at end portions 32 (both end portions 32a and 32b in FIGS. 5 and 6), and a bag-like space 33 is formed between the skin sheet body 5 and the top sheet 3. It is preferable. By configuring in this way, since excrement (stool and urine) is held in the bag-shaped space 33 described above, for example, even when the amount of excretion excreted at a time is large, There is no leakage to the outside. In addition, the amount of stool adhering to the wearer can be reduced. Furthermore, when exchanging the urine / feces pad 1b, the excrement is prevented from flowing out and spilled over, so that bedding such as clothes and sheets is not soiled.

Further, in the urine / feces pad 1b of the present embodiment, the skin sheet body 5 has at least one side edge 31 of the back sheet 4 (in FIGS. 1 to 3), like the male urine pad 1a. both side edges 31a, 31b) from the Ru der those constructed by folding a portion extending integrally on the surface of the top sheet 3 to the side. Since the urine / feces pad 1b configured as described above has a simple structure, it can be manufactured easily and at low cost. Moreover, since it can produce by applying the existing production line for producing the conventional tape type diaper etc., it is excellent also in terms of equipment cost.

  Moreover, as shown in FIGS. 1-3, in the urine / feces pad 1b of this embodiment, it is preferable that at least one pair of the three-dimensional gathers 13 is formed on the surface of the top sheet 3. By comprising in this way, the side leakage of the excretion (especially urine) which the wearer excreted can be prevented effectively.

  Further, as shown in FIGS. 9 and 10, at least a pair of solid gathers 14 may be formed on the surface of the skin sheet body 5 that faces the top sheet 3. Such a three-dimensional gather 14 can have a function as a check valve for the opening 11 of the skin sheet body 5 and effectively prevent the backflow of excrement such as urine and watery stool from the opening 11. can do. Such a three-dimensional gather 14 may be an inversion gather that tilts toward the inside of the opening 11, but the absorbent article can effectively prevent the backflow of excrement from the opening 11. It is preferable that the outer gather is inclined toward the outside of 1 (specifically, the outside of the opening portion 11 of the opening 11).

  Further, in the urine / feces pad 1b of the present embodiment, as shown in FIG. 11, the skin sheet body 5 and the top sheet 3 have the side edge 31a and the side edge on the longitudinal end 32 side of the opening 11. It may be joined in a part between 31b. In addition, there is no restriction | limiting in particular about the method of joining the skin sheet body 5 and the top sheet 3, For example, the conventionally well-known joining method by heat | fever including a heat seal, an ultrasonic wave, etc. can be used suitably.

The urine / feces pad 1b shown in FIGS. 1 to 3 has a skin sheet body 5 integrally extended from the back sheet 4 to the side thereof on the surface of the top sheet 3 outside the side edge of the absorbent body 2. It is configured to be folded back. Furthermore, as shown in FIGS. 13 and 14, the urine / feces pad 1 b according to the present embodiment includes a skin sheet body 5 integrally extended from the back sheet 4 to the side thereof, and the side edges of the absorbent body 2. together with a part of, Ru der those constructed by folding back on the surface of top sheet 3. With this configuration, a part of the folded absorbent body 2 serves as a leak-proof wall, and the lateral leakage of urine excreted by the wearer can be achieved without arranging the three-dimensional gather 13 as shown in FIG. Can be effectively prevented.

[4] Skin sheet body:
The skin sheet body is a sheet body for separating the wearer's skin and the top sheet, and is disposed on the surface of the top sheet, and an opening through which feces can pass and / or an opening into which a male genitalia can be inserted. The part is formed. By providing this skin sheet body, the skin sheet body first comes into contact with the wearer's skin, and therefore the top sheet disposed at the lower part of the skin sheet body is less likely to directly contact the wearer's skin. . That is, the wearer's skin and the top sheet are separated from each other. Moreover, the shielding layer called a skin surface sheet | seat body will also interpose between a top sheet and a wearer's skin.

  As a material which comprises a skin surface sheet body, the nonwoven fabric, mesh sheet | seat, film, etc. which consist of resin, such as polyethylene, a polypropylene, and polyester, can be used, for example.

  In addition, when using the absorbent article of this invention as a urine pad for men, it is preferable to use a nonwoven fabric in the point that the touch is favorable. When used as a urine pad for men, in order to excrete with a male genitalia inserted into the opening of the skin sheet body, the skin sheet body may be configured so that the excreted urine does not pass through. preferable. For this reason, it is preferable that the area | region in which the opening part of the skin sheet body is formed consists of a water-repellent material or a liquid-impermeable material. In particular, a water-repellent material (such as a water-repellent nonwoven fabric) is preferable in that it can maintain a light touch (dryness) even when worn for a long time.

  Moreover, when using the absorbent article of this invention as a urine pad, it is preferable to use a nonwoven fabric in the point that the touch is favorable. These materials may be liquid permeable, liquid impermeable, or water repellent. However, the area where the skin sheet body has at least the opening is formed from a water-repellent material (water-repellent material) in that it can maintain a light touch (dryness) even when worn for a long time. It is preferable that it consists of a nonwoven fabric etc.). As described above, when used as a urine pad, a urine permeable region through which urine can permeate may be formed by using a liquid permeable material for a part of the skin sheet body.

As shown in FIGS. 7 and 8, the skin sheet body folds side flaps 5 a, 5 b integrally extending from both side edges 31 a, 31 b of the back sheet 4 to the side thereof onto the surface of the top sheet 3. Can be formed .

  Although there is no restriction | limiting in particular about the shape of the opening part of a skin surface sheet body, According to the use, it can select suitably. For example, when used as a male urine pad, a shape that allows a male genitalia to be inserted and held well, for example, so-called openings (holes such as circular openings, elliptical openings, rhombus openings) ). In addition, when used as a urine / feces pad, when excreted by being placed near the crotch part of clothing or diapers, the excreted feces can be passed well, for example, a circular opening In addition to so-called openings (holes) such as circular, elliptical, and diamond-shaped openings, linear slits, cross-shaped slits, slits such as star-shaped slits that intersect three or more slits, and the like can be given. . Furthermore, as shown in FIG.16 and FIG.17, the notch-shaped opening part 11 in which the opening part 11 covers the longitudinal direction edge part 32 or the side edge 31 of the absorbent article 1 may be sufficient. . Here, FIG.16 and FIG.17 is a top view which shows other embodiment of the absorbent article of this invention.

  When the skin sheet body is extended from at least one side edge of the back sheet, the side from the side edges 31a and 31b of the back sheet 4 as shown in FIGS. In the side flaps 5a and 5b that are integrally extended in the direction, a notch 46 corresponding to the shape of the opening 11 (see FIG. 1) is formed, and the respective side flaps 5a and 5b are attached to the top sheet 3. The opening 11 (see FIG. 1) may be formed by the notch 46 when folded on the surface.

  When the absorbent article of the present invention is used as a urine / feces pad, a urine passage opening may be separately formed in the skin sheet body as a urine permeable region through which urine can permeate. By forming the urine passage opening, the urine excreted by the wearer through the opening can be reliably introduced into the space between the skin sheet body and the top sheet. The urine passage opening is preferably formed in a portion closer to the wearer's front body than the opening through which stool can pass.

  Moreover, in the absorbent article of this invention, as above-mentioned, you may arrange | position an elastic material (opening part elastic material) along a part of inner periphery of the opening part of a skin surface sheet body. By comprising in this way, when it folds and uses in the approximate center part of the longitudinal side of an absorptive article, a skin sheet body expands and contracts, and a skin sheet sheet and a top sheet are separated apart reliably. Thus, a space can be formed between the skin sheet body and the top sheet. Thereby, when it is used as a urine / feces pad, it is possible to secure a sufficient space to accommodate the wearer's feces. Further, when used as a male urine pad, the male genital can be inserted into the opening and fixed well, and the opening can be expanded and contracted according to the size of the wearer's male genital.

  As the opening stretchable material, stretchable materials that have been used in conventional disposable diapers can be suitably used. Specific examples include elastic rubber, elastic film, elastic foam (urethane foam, etc.), etc., as well as thread rubber and flat rubber made of elastic materials such as natural rubber and synthetic rubber (urethane rubber, etc.). .

  The arrangement pattern of the opening stretchable material is not particularly limited as long as it is a pattern that can exhibit the above-described effect, but is preferably arranged in a pattern that can reliably exert a stretching force on the opening. For example, as shown in FIG. 1, the opening stretchable material may be arranged linearly along a part of the inner periphery of the opening. For example, as shown in FIG. You may arrange | position the opening part expansion-contraction material 12 so that it may surround. Moreover, although illustration is abbreviate | omitted, you may arrange | position an opening expansion-contraction material by patterns, such as circular, an ellipse, and a rhombus, for example. Here, FIG. 18 is a plan view showing another embodiment of the absorbent article of the present invention.

  In addition, when using what formed by folding up the side flap extended from the both-sides edge of a back sheet on the surface of a top sheet as a skin surface sheet body, the side flap extended from each side edge It is preferable not to arrange the above-described opening stretchable material in the overlapping region. Thus, in the part which a side flap overlaps, since the thickness of a skin surface sheet | seat body becomes thick, the expansion-contraction force of an opening part expansion material may become difficult to act.

  The opening stretchable material is fixed to the skin sheet by an adhesive or other means. The fixing method may be, for example, adhesion using a hot melt adhesive or other highly fluid adhesive, or may be welding by heat such as heat sealing or ultrasonic waves.

  The opening stretchable material is preferably fixed in an expanded state in order to cause a sufficient stretching force to act on the opening. For example, when the opening stretchable material is natural rubber or synthetic rubber, it is preferably fixed in a stretched state of 120 to 400%, and more preferably fixed in a stretched state of 200 to 300%. By fixing in the stretched state in such a range, it is possible to cause a sufficient stretching force to act on the skin sheet body and to prevent the opening from being reduced more than necessary.

  The arrangement method of the opening stretchable material is not particularly limited. For example, the skin sheet is formed by bonding two sheet materials (upper sheet and liner sheet), and the opening is formed between the upper sheet and the liner sheet. It is preferable to arrange so as to sandwich the elastic material. Employing such an arrangement method is preferable because a stretching force can be imparted to the skin sheet body with the minimum necessary stretching material.

  Even in the case of adopting the configuration as described above, the skin surface sheet body is sufficient if the portion on which the opening stretchable material is disposed is composed of two sheet materials, and the entire skin sheet body is not necessarily provided. It is not necessary to be constituted by two sheet materials. For example, the portion where the opening stretchable material is disposed may be constituted by two sheet materials, and the other portion may be constituted by one sheet material.

[5] Absorber:
The absorber is a member for absorbing and holding the wearer's urine. The absorber is made of an absorbent material because it needs to absorb and retain the wearer's urine and body fluid.

  Examples of the absorbent material constituting the absorber include conventionally known absorbent materials usually used for disposable diapers and other absorbent articles, such as fluff pulp, super absorbent polymer (Super Absorbent Polymer; hereinafter referred to as “SAP”). And a hydrophilic sheet. It is possible to use wood pulp or non-wood pulp defibrated as fluff pulp, sodium polyacrylate as SAP, tissue, absorbent paper, hydrophilized nonwoven fabric as hydrophilic sheet preferable. Moreover, as a countermeasure against the loss of shape of the absorbent body, synthetic fibers such as heat-sealing fibers may be included.

  These absorbent materials are usually used as a single-layer or multi-layer mat. Under the present circumstances, 1 type may be used independently among the said absorptive materials, and 2 or more types may be used together. Especially, what used together about 10-500 mass parts SAP with respect to 100 mass parts of fluff pulp is preferable. At this time, the SAP may be uniformly mixed in each mat of fluff pulp, or may be arranged in layers between the layers of the multilayer fluff pulp.

  It is preferable that the absorber is interposed at least in part between the top sheet and the back sheet. Usually, the absorber is interposed between the top sheet and the back sheet by being sandwiched between the top sheet and the back sheet and sealing the peripheral edge thereof. Therefore, the flap part in which the absorber is not interposed is formed between the top sheet and the back sheet at the peripheral part of the absorber. The absorber is interposed in at least a part between the top sheet and the back sheet.

  It is preferable that the absorber is entirely wrapped with a hydrophilic sheet. Such a configuration has an advantage that SAP can be prevented from leaking from the absorber and shape stability can be imparted to the absorber.

  Although there is no restriction | limiting in particular about the shape of an absorber, The shape used in the conventional disposable diaper and other absorbent articles, for example, a rectangular shape, an hourglass type, a gourd type, a T shape etc. can be mentioned. The absorbent article 1 shown in FIG. 1 is an example in which an hourglass-type absorber is used as the absorber 2. Such an hourglass-shaped absorbent body is particularly suitable when a space is easily formed between the skin sheet body and the top sheet when the absorbent article is used by being folded in two at the substantially central portion on the longitudinal side of the absorbent article. Can be used.

  Moreover, for example, as shown in FIG. 12, when the end stretchable material 15 is disposed on at least one end 32 side in the longitudinal direction of the absorbent article 1, the absorptive material in which the end stretchable material 15 is disposed. As shown in FIG. 19, notches may be formed in the corners of the absorbent body 2 such as a rectangular shape or an hourglass shape so that the end portion side of the article 1 is easily contracted (in FIG. 19, an hourglass shape). A notch is formed in one corner of the absorbent body 2). Moreover, for example, as shown in FIG. 17, when a notch-shaped opening 11 is formed such that the opening 11 is applied to a part of the longitudinal end 32 or the side edge 31 of the absorbent article 1. As shown in FIG. 20, a T-shaped absorber 2 can be used. Here, FIG.19 and FIG.20 is a top view which shows other embodiment of the absorbent article of this invention.

  In addition, a sheet (second sheet) for diffusing liquid such as urine and body fluid may be incidentally disposed on the surface side of the absorber (for example, between the absorber and the top sheet). . When this second sheet is attached, due to the wearer's posture, etc., even when the space on the back side of the top sheet is not sufficiently formed, the absorption rate of urine, body fluid, etc. is difficult to decrease, and the absorption rate decreases. It is possible to prevent leakage of urine and body fluids.

  Examples of the material constituting the second sheet include hydrophilic and liquid-permeable materials such as woven fabric, non-woven fabric, porous plastic, and fluff pulp. Examples of these constituent materials include polypropylene, polyethylene, polyester, rayon, pulp, and composite fibers thereof. As the pulp, crimped fibers such as curly cellulose fibers can be suitably used.

[6] Top sheet:
A top sheet is a sheet | seat arrange | positioned so that the surface (surface located in a wearer's skin side, when an absorbent article is mounted | worn) may be coat | covered. At least a part (all or a part) of the top sheet is made of a liquid-permeable material because the absorber disposed on the back surface side needs to absorb the wearer's urine. Usually, at least near the surface of the absorber, it is made of a liquid-permeable material that can permeate the wearer's urine and body fluid. As long as at least a part is made of the liquid permeable material, the entire top sheet is not necessarily made of the liquid permeable material.

  Examples of the liquid permeable material constituting the top sheet include a woven fabric, a nonwoven fabric, and a porous film. Among these, it is preferable to use a non-woven fabric made of a thermoplastic resin such as polypropylene, polyethylene, polyester, or nylon and subjected to a hydrophilic treatment. There is no restriction | limiting in particular also about the kind of nonwoven fabric, The conventionally well-known nonwoven fabric manufactured by various manufacturing methods, such as air through (card hot air), card | curd embossing, and a spun bond, can be used suitably. The top sheet may be composed of a single sheet material, but may be composed of a plurality of sheet materials.

[7] Backsheet:
A backsheet is a sheet | seat arrange | positioned so that the back surface (surface located in a wearer's clothing side, when an absorbent article is mounted | worn) may be coat | covered. The back sheet is made of a liquid-impermeable material because it is necessary to prevent the wearer's urine from leaking outside the absorbent article. In addition, as described above, in the absorbent article of the present invention, such a back sheet and a skin sheet body may be composed of an integral sheet.

  Examples of the liquid-impermeable material constituting the backsheet include a liquid-impermeable film made of a resin such as polyethylene. Among these, a microporous polyethylene film is preferably used. This microporous polyethylene film has a large number of fine pores of 0.1 to several μm, and is liquid-impermeable but has moisture permeability, so it is possible to prevent stuffiness inside the absorbent article. There is an advantage that you can.

  Note that a sheet material (cover sheet) may be bonded to the outer surface of the back sheet. This cover sheet is used to reinforce the back sheet and improve the feel (tactile feeling) of the back sheet.

  Examples of the material constituting the cover sheet include paper cloth, woven fabric, and non-woven fabric. In particular, the use of a paper cloth can effectively prevent skin troubles such as rash.

  Moreover, in the absorbent article of this invention, as shown in FIG. 21, you may have the fixing means 16 for fixing to clothing or a diaper on the back surface of the back seat | sheet 4. As shown in FIG. Examples of such fixing means 16 include an adhesive tape and a mechanical fastener. By further including such a fixing means 16, the absorbent article 1 of the present invention can be fixed to the inner surface of clothes, diapers, etc., and displacement of the absorbent article 1 can be effectively prevented. it can. Here, FIG. 21 is a plan view showing another embodiment of the absorbent article of the present invention.

  The above-mentioned “mechanical fastener (also referred to as a surface fastener)” is a surface fastener that uses mechanical coupling, and for example, a large number of protrusions (such as a hook, mushroom, and hook) are formed on the surface. A combination of the projected member (hook member) and a recess member (loop member) having loop-like fibers arranged on the surface is often used. In this fastener, the hook material is overlapped on the surface of the loop material, and a large number of protrusions of the hook material are engaged with the surface of the loop material, so that both members can be attached and detached firmly and firmly. It can be done. Since the hook material of the mechanical fastener can be engaged with a material having a fibrous surface such as woven fabric, non-woven fabric, felt, and pile in addition to the loop material of the mechanical fastener corresponding thereto, the fiber It can be fixed by being engaged with clothing or a diaper made of a material having a shaped surface.

  With regard to the size and position of such fixing means, the absorbent article can be fixed to the inner surface of clothes, diapers, etc., and a binding force that does not cause displacement of the absorbent article can be obtained. For example, the fixing means may be disposed on the entire back surface of the back sheet, or a part of the back surface of the back sheet (for example, in FIG. 21, the end side in the longitudinal direction of the absorbent article). You may arrange in two places.

[8] Solid gather:
The three-dimensional gather is a member for preventing side leakage of the urine excreted by the wearer, and is a leak-proof wall configured to stand up three-dimensionally. In the absorbent article of the present invention, at least a pair of solid gathers may be formed on the surface of the top sheet, or at least a pair of solid gathers may be formed on the surface facing the top sheet of the skin sheet body. Good.

  When at least a pair of solid gathers are formed on the surface of the top sheet, even if urine spreads along the surface of the top sheet, the solid gathers serve as a breakwater, preventing leakage of urine to the outside. It can be effectively prevented.

  When at least one pair of three-dimensional gathers are formed on the surface of the skin sheet body that faces the top sheet, the three-dimensional gather serves as a check valve for the opening of the skin sheet body. The backflow of excrement can be effectively prevented.

  The structure of these three-dimensional gathers can employ | adopt the structure used for the conventional disposable diaper and other absorbent articles. For example, it is possible to suitably use a material in which a stretchable material (a three-dimensional gathered stretchable material) is arranged on a part of the sheet material, and a gather is formed on the sheet material by the three-dimensional gathered stretchable material.

  As the sheet material constituting the three-dimensional gather, it is preferable to use a water-repellent material from the viewpoint of improving the leak-proof property of the three-dimensional gather. Non-woven fabrics such as spunbond and card embossing may be used as the water-repellent material, but SMS (spunbond / meltblown / spunbond) and SMMS (spunbond / meltblown / meltblown / spun) are used because of their high water pressure resistance. It is preferable to use a non-woven fabric such as a bond.

  In such a three-dimensional gather, a sheet material completely different from the top sheet and the back sheet constituting the absorbent article is bonded to both side edges of the top sheet and the surface facing the top sheet of the skin sheet body. Can be formed. In addition, for example, a three-dimensional gather can be formed by folding back a part of a top sheet or a back sheet constituting the absorbent article.

  As the three-dimensional gather stretchable material, the same stretchable material as the already described opening stretchable material can be used. One or more three-dimensional gather elastic materials may be arranged for one three-dimensional gather. Moreover, there is no restriction | limiting in particular also about an arrangement position. For example, it may be arranged in the vicinity of the lower end edge (standing line) of the three-dimensional gather, or between the upper end edge and the lower end edge (standing line) of the three-dimensional gather, but is preferably arranged in the vicinity of the upper end edge of the three-dimensional gather. .

  For example, in the absorbent article 1 shown in FIG. 2, an example in which a pair of three-dimensional gathers 13 a and 13 b are arranged on the surface of the top sheet 3 is shown. The three-dimensional gathers 13a and 13b are formed by folding the end portions of the sheet material constituting the three-dimensional gathers (ends corresponding to the upper edge 34 of the three-dimensional gathers 13a and 13b), and two three-dimensional gathers at the folded portions. The elastic material 36 is disposed so as to be sandwiched therebetween. FIG. 10 shows an example in which a pair of three-dimensional gathers 14 a and 14 b are arranged on the surface of the skin sheet body 5 that faces the top sheet 3. In addition, this solid gather 14 can use what was comprised similarly to the solid gather 13 used for the absorbent article 1 shown in FIG.

  The height of the three-dimensional gather (length from the lower end edge to the upper end edge) is preferably 5 to 80 mm, and more preferably 10 to 40 mm. In addition to being able to ensure a sufficient leak-proof effect by setting it to 5 mm or more, by preventing the problem that the three-dimensional gather covers the surface of the top sheet and impedes the absorption effect by setting it to 80 mm or less. Can do.

  The types of three-dimensional gathers are: (1) Inverted gathers that tilt toward the inner side of the absorbent article, (2) Outer gathers that tilt toward the outer side of the absorbent article, and (3) Part of the height direction In addition, a three-dimensional gather (such as a C-fold gather or a Z-fold gather) having a bent portion or a folded portion may be used. For example, when a pair of three-dimensional gathers 13a and 13b are arranged on the surface of the top sheet 3 as shown in FIG. On the other hand, when a pair of three-dimensional gathers 14a and 14b as shown in FIG. 10 is disposed on the surface of the skin sheet body 5 facing the top sheet 3, the urine backflow from the opening 11 is effectively prevented. In order to be able to do it, it is preferable that it is an overturn gather.

  In addition, in the disposable diaper of this invention, although at least one pair of solid gathers is required, two or more pairs may be formed.
