Description

  The present invention relates to an absorbent article that absorbs body fluid such as urine.

  Urine pads are known as absorbent articles that cope with mild urine leaks and the like. The urine pad is attached to a disposable diaper, an undergarment, and a cloth-type pants-type exterior body called a holder pants made for holding the urine pad, and absorbs body fluid such as urine. Urine pads are detachably attached to the crotch area of disposable diapers, underwear, and holder pants, and are often used in a method of replacing only the urine pads when absorbing body fluid. For this reason, the urine pad is required to have a function to cope with various leg movements and to rapidly and firmly absorb a large amount of urination and the like.

  Urine pads have to absorb large amounts of low-viscosity body fluids such as urine quickly, so an absorbent body with a width sufficient to cover crotch etc. firmly is placed, and to prevent leakage, it should be longer than crotch width Many are wide.

  In addition, there is also a device in which the absorber is more closely attached to the skin in the crotch. For example, in Patent Document 1, although it is a disposable diaper and not a urine pad, three slits are made in the absorber in advance, and it is deformed into a W shape by pulling on the left and right legs in the crotch, and it adheres to the crotch It describes what you want to do.

  Also, if a gap is created between the urine pad and the skin due to various movements of the leg, body fluid is likely to leak from the gap. Then, in order to prevent such a bodily fluid leak, the solid gathers structure which made the side sheet stand up from the side edge part of the absorber main body is applied. By the side sheet by this three-dimensional gathers structure being located in the end of an absorber main part, a three-dimensional gathers part becomes wrinkles and suppresses the leak of a bodily fluid.

JP, 2011-177310, A

  However, in the configuration in which three slits are provided in the crotch described in Patent Document 1 and the structure is bent, both ends in the width direction of the crotch portion are in a state where the absorber is bent in a valley break with respect to the skin. For this reason, a portion where four sheets of the absorber overlap in the width direction comes out, and depending on the wearer, the feeling of stiffness and stiffness of the crotch portion may be strongly felt, and the wearing feeling may be reduced. Although the distribution of the polymer is adjusted in order to suppress the discomfort, when drawing of the left and right legs is frequent such as sitting for a long time, the degree of adjustment of the polymer may not be sufficient.

  Moreover, even if it applies the side sheet of a solid gather to the thing which an absorber bends in a W shape in this way, there existed the following problem. Depending on the position of the three-dimensional gather of the side sheet provided at the side end of the absorber, the three-dimensional gather portion may lie on the skin due to the absorber bending in a W shape. Thus, with the deformation of the absorber, there may be a case where the descent function by the solid gather can not be sufficiently exhibited.

  In addition, since three slits aligned in the width direction are formed in the narrowed portion of the crotch portion, the strength of the absorber is reduced, and the absorber is appropriate in the state of being worn by the wearer Shape could cause the body fluid to leak.

  The present invention has been made in view of such conventional problems, and the problem is to make an absorbent article which adheres well to the skin by various movements of the legs and which can sufficiently exhibit a caking function in a three-dimensional gather portion. It is to provide.

  The absorbent article of the present invention comprises an absorbent body, a liquid-permeable top sheet superposed on one side of the absorbent body, a liquid-impermeable back sheet superposed on the other side of the absorbent body, and a wearer. Extends in a first direction from the wearer's ventral side to the crotch and back side in the wearing state, and at least a part is joined to the top sheet on both sides in the width direction orthogonal to the first direction of the top sheet A pair of side sheets, which are provided on the inner side in the width direction with respect to the joining portion with the top sheet, with an erected area not joined to the top sheet, and in the erected area An absorbent article comprising a side sheet provided with a three-dimensional gather to form a solid gather, wherein the absorbent body, when worn on the wearer, has both ends in the portion located under the crotch compared to the other portions Width direction The widthwise inner end of the side sheet is on the widthwise end of the narrow portion of the absorbent body or in the widthwise direction than the widthwise end of the narrow portion. It is characterized by being located inside and extending from the width direction outside rather than the width direction end of a narrow part.

It is the partially broken top view which looked at the urine pad to which this invention was applied from the skin contact surface side. FIG. 2 is a perspective view showing the urine pad shown in FIG. 1 in a disassembled state. It is a schematic perspective view of the urine pad shown in FIG. It is the top view which looked at the urine pad shown in FIG. 1 from the non-skin opposing surface side. It is sectional drawing of the urine pad corresponding to the state cut | disconnected by the VV line | wire of FIG. It is sectional drawing of the urine pad corresponding to the state cut | disconnected by the VI-VI line of FIG. It is the typical fragmentary perspective view which cut the crotch part of the urine pad in the wearing condition to a wearer along the cross direction. It is sectional drawing to which the cutting end surface of the urine pad shown in FIG. 7 was expanded.

  One embodiment of a urine pad to which the present invention is applied will be described in detail with reference to FIGS. 1 to 8.

  The urine pad according to the present invention is attached to, for example, a tape-type diaper, a pant-type diaper, or a holder pant, and is worn by the wearer in combination with these.

  In the present embodiment, the “longitudinal direction” refers to the first direction from the front to the back in the urine pad. That is, when the wearer wears the urine pad and the like of the present embodiment, it means a direction extending from the ventral side to the crotch and across the dorsal side. Further, the “width direction” means a second direction which is orthogonal to a direction connecting one side end and the other side end of the urine pad, that is, a longitudinal direction (first direction). In the drawings, the longitudinal direction is indicated by the Y axis, and the width direction is indicated by the X axis.

FIG. 1 shows a plan view of the urine pad 12 as viewed from the skin contact side, and FIG. 4 shows a plan view of the non-skin facing side, along lines V-V and VI-VI in FIG. The cross-sectional structure along is shown in FIG. 5 and FIG. The urine pad 12 in the present embodiment is in the form of an elongated rectangular sheet, and when worn on the wearer, extends from the ventral side to the dorsal side through the crotch. Hereinafter, a portion located on the ventral side of the urine pad 12 will be referred to as a front body 12F, a portion located on the back side as a back body 12R, and a portion located on the crotch will be referred to as a crotch 12C for convenience. The length L _C of the crotch 12 C along the longitudinal direction of the urine pad 12 is about 20 to 70% of the total length L of the urine pad 12. This relationship is because the length of the urine pad 12 itself differs depending on the application of the urine pad 12 (light incontinence pad, urine pad portion in diaper, etc.). Accordingly, the length L _C of the crotch portion 12C can also be defined as an appropriate length for covering the crotch portion of the wearer.

  The urine pad 12 has an absorbent property comprising a liquid impermeable back sheet 19, a liquid permeable top sheet 20 having a size slightly smaller than the back sheet 19, and an elongated sheet-like absorbent body 21. A main part is constituted by the main body 10 and a pair of left and right side sheets 22 impermeable to liquid on both the left and right sides in the width direction on the skin opposing surface side of the absorbent main body 10 over the entire longitudinal direction. The urine pad 12 of the present embodiment has a substantially rectangular shape in which the longitudinal direction from the ventral side to the dorsal side is longer than the width direction, but not limited to this, the length in the longitudinal direction and the length in the width direction are substantially the same It can also be made to correspond to the approximate square shape of, or the outline shape of the absorber 21 described later. In short, the dimensions and the contour shape of the urine pad 12 can be appropriately selected according to the figure of the person to be worn and the like.

  The absorber 21 is disposed between the top sheet 20 and the back sheet 19, and absorbs and holds body fluid such as urine that has passed through the top sheet 20. In order to perform such a function, the absorber 21 is comprised by the absorptive material, and the absorptive material can employ | adopt the well-known material which has an absorptive function. Specifically, for example, fluff pulp, super absorbent polymer (SAP), or a hydrophilic sheet may be used. One of these absorbent materials may be used alone, or two or more thereof may be used in combination. In this embodiment, a mixture of fluff pulp with super absorbent polymer (SAP) is made into a mat, and a single layer or a laminate of multiple layers is used, and the whole is covered with the tissue 23.

The absorber 21 has a narrow portion 21c in which the width of the portion corresponding to the crotch portion 12C is narrower than the width of the portion corresponding to the front body 12F and the rear body 12R. That is, the width of the portion of the absorbent body 21 corresponding to the front body 12F and the rear body 12R is substantially equal, and the narrow portion 21c of the absorbent body 21 has an hourglass shape which is scooped toward the center side. the minimum width W _C of the 21c is the same or slightly wide degree and crotch of the wearer. Thus, for the narrow portion 21c of the absorbent body 21, by a form of gouge increase its widthwise end portions, when worn, the narrow portion 21c of the absorbent body 21 falls within the crotch, the crotch Can be suppressed. From such a point of view, it is also effective to make the contour shape of the urine pad 12 itself into an hourglass shape adapted to the contour shape of the absorber 21. The shape of the narrow portion 21c can be formed by combining an arc of arbitrary curvature and a straight line, combining a plurality of straight lines, or an arc of a single curvature. The width W of the urine pad 12 itself is wider than the width of the crotch of the wearer, and can sufficiently cover the crotch and the ventral and dorsal sides connected from the crotch.

  Next, the top sheet 20 is in direct contact with the skin of the wearer's crotch and is for transmitting body fluid such as urine to the absorber 21. Therefore, the top sheet 20 is formed of a liquid-permeable material having a good touch. Specifically, a non-woven fabric made of a thermoplastic resin such as polypropylene, polyethylene, polyester, or nylon may be subjected to a hydrophilization treatment.

  The back sheet 19 is a member for preventing the liquid absorbed by the absorber 21 from leaking out. Therefore, the back sheet 19 is made of a liquid impermeable material, that is, a liquid repellent material, and a liquid impermeable film made of, for example, a polyethylene resin can be employed. Moreover, in order to ensure air permeability without leaking the liquid, it is preferable to use a microporous polyethylene film in which a plurality of fine pores of 0.1 to 4 μm are formed.

  Further, as shown in the cross-sectional view of FIG. 6, the top sheet 20 extends to the left and right outside in the width direction of the absorber 21 and wraps the end of the absorber 21. In addition, by bonding a part of the top sheet 20, that is, a portion positioned on the non-skin opposing surface side and the back sheet 19, the top sheet 20 and the back sheet 19 include the absorber 21.

  In addition, a liquid-permeable second sheet (not shown) may be provided between the top sheet 20 and the absorber 21. The second sheet is a sheet-like member disposed for the purpose of diffusing the liquid that has permeated the top sheet 20. By providing the second sheet, even if the urine pad 12 is compressed when the wearer is seated, and a sufficient space is not formed between the absorber 21 and the top sheet 20, the liquid is easily diffused. Since the liquid is easily diffused, it is possible to suppress a decrease in the liquid absorption rate. As a material which comprises a second sheet | seat, the liquid-permeable woven fabric, a nonwoven fabric, a porous film etc. can be used similarly to the top sheet 20. FIG.

  The pair of side sheets 22 form a solid gather 24g along side edges of the absorbent body 10 to prevent lateral leakage of body fluid. As the side sheet 22, one having water repellency and air permeability is suitable. As a specific material, for example, a non-woven sheet formed by a method such as card embossing or spun bonding can be used, and it is particularly preferable to use a non-woven sheet such as SMS or SMMS having high waterproofness and high breathability. Further, the side sheet 22 may be a woven fabric or a non-woven fabric subjected to a water repellent finish.

As shown in FIGS. 1 and 5, the side sheets 22 are belt-like sheets provided on both ends in the width direction of the absorbent body 10 and extending in the longitudinal direction. Side sheets 22 is divided from the width direction outside the junction region Z _C the standing area Z _S. Width joint region Z _C located outwardly, specifically, located on the skin-facing surface of the absorbent body 21, and a portion to be joined with the topsheet 20, extending in the widthwise outer side than the absorbent body 21 And there is a portion joined to the back sheet 19. On the other hand, the standing area Z _S of the side sheet 22 is not fixed to the topsheet 20, the end portion in the width direction inner side is a free end, these longitudinal ends is joined to the topsheet 20 It is in a state of

Here, the width L ₁ of the distance to the boundary between the junction region Z _C the standing area Z _S of the side sheets 22 from the side end edges of the absorbent body 21 in the narrow portion 21c, the width of the standing area Z _S of the standing gathers 24g Let W _{G be} the maximum width of the portion of the absorber 21 corresponding to the front body 12F and the rear body 12 R as W _E , the following relationship:
(W _C / 2) <L ₁ + W _G
L ₁ ≦ W _G
(W _C / 2) + L ₁ <(W _E / 2)
It is preferable to satisfy More specifically, the minimum width W _C of the absorber 21 is desirably about 40 to 60% of the maximum width W _E of the absorber 21, and W _C is 60 mm to 160 mm, W for adults. _E is preferably in the range of 120 mm to 260 mm.

Further, the free end 22a of the standing area Z _S of the side sheets 22, the rubber-like elastic member 24 such as rubber threads are secured in the longitudinal direction. While the rubber-like elastic member 24 is stretched, it is fixed along the longitudinal direction of the free end portion 22a, by the rubber-like elastic member 24 contracts, three-dimensional gathers 24g to the standing area Z _S of the side sheets 22 is formed Be done. Further, as the rubber-like elastic member 24 is contracted, the side sheet 22 is drawn to the center in the longitudinal direction, and as shown in FIG. 3, the free end 22a rises in the direction in which the free end 22a abuts on the skin of the wearer. It will be.

  As shown in FIG. 4, a mounting portion 25 for bonding the urine pad 12 to a diaper or the like is provided on the non-skin-facing surface of the front body 12F of the urine pad 12. The mounting portion 25 is composed of an adhesive layer 25a and a release paper 25b for sealing the adhesive layer 25a until use. When the urine pad 12 is used, the release paper 25b is removed to expose the adhesive layer 25a, and the adhesive layer 25a is joined to an inner sheet such as a diaper, for example, a top sheet, whereby the urine pad 12 can be used as a diaper. Join the The structure of the mounting portion 25 is not limited to this, and can be provided on the rear body 12R, and it is effective to join the exterior member 11 in a replaceable manner using a surface fastener or the like.

By the way, in the state shown in FIG. 1, the side sheet 22 is positioned such that the end on the inner side in the width direction is located at the center side in the width direction from the side edge of the absorber 21. The width direction inner end of the standing area Z _S of the side sheet 22 (the standing area tip) is adapted to position on the end of the narrow portion 21c of the absorber 21. That is, the width W _S of the side sheet 22 in the present embodiment is equal to the length from the widthwise outer end of the absorbent main body 10 to the inner end of the narrow portion 21c of the absorbent body 21, but enters further inside. It may be long to some extent. In this case, it is preferable to fit within about 30 mm from the side edge of the narrow portion 21 c of the absorber 21. If the width W _S of the side sheet 22 is expanded inward than this, the top sheet 20 is covered with the hydrophobic side sheet 22 when the solid gather 24 g falls inward when worn, and the exposed area of the top sheet 20 May lead to urine leakage. Therefore, the width W _S of the side sheet 22 is desirably about 20 to 30% of the width W of the urine pad 12.

And in the center of narrow part 21c of absorber 21, bending part 21a extended along the longitudinal direction is provided. The bent portion 21 a is disposed at a position obtained by dividing the width W _C of the narrow portion 21 c of the absorber 21 into two halves and into a position obtained by dividing the width W of the urine pad 12 into two parts. The bent portion 21a is a pre-processed bendable portion that is preprocessed so that the urine pad 12 is drawn in the width direction by the movement of the wearer's thighs and that the urine pad 12 is bent preferentially over other portions when it is bent. It is a department. The bent portion 21a is folded so that the portion protrudes as seen from the skin facing surface side. That is, it is formed as a mountain fold which can be broken toward the skin. The length from the widthwise end of the urine pad 12 to the bent portion 21 a is about half the width W of the urine pad 12. The urine pad 12 is preferably disposed so that its widthwise center line is located at the center of the crotch of the wearer, and the width is substantially bisected such that the bent portion 21a is located at the center of the crotch It is arranged in the position.

  As shown in FIG. 6, the bent portion 21 a can be compressed and formed by embossing the absorber 21. Alternatively, slits may be formed in the absorber 21. The compression may be performed from the skin facing surface side of the absorber 21, from the skin non-facing surface side, or from both sides. For example, the bending portion 21 a is embossed after being compressed from the non-skin-facing side of the absorber 21. Due to the embossing creasing, the bent portion 21a is bent preferentially over the other portions of the absorber 21. In order to obtain a better fit, it is also effective to bifurcate the end of the bent portion 21a located on the rear body 12R side of the urine pad 12 or to widen the width thereof.

Side sheets 22 is joined to the topsheet 20 and backsheet 19 at the junction region Z _C, in the crotch portion 12C of the urine pad 12, it is directly below the side sheet 22 in a state where there is no absorber 21 ing. Further, as shown in FIG. 6, the proximal end of the standing area Z _S, i.e. the boundary between the standing area Z _S and the junction region Z _C is separated by a W _G from the side edge of the narrow portion 21c of the absorber 21 It will be. In other words, the distance L ₁ from the side edge of the narrow portion 21c of the absorbent body 21 in this embodiment, to the boundary between the standing area Z _S and the junction region Z _C is the width of the standing area Z _S of the side sheets 22 Although it is equal to W _G , in the case of a urine pad for adults, it is desirable that this distance L ₁ be 20 mm or more.

As shown in FIG. 6, the urine pad 12 with such a structure is such that the portion of the three-dimensional gather 24 g of the side sheet 22 rises high centering on the narrow portion 21 c of the absorber 21.

And when a wearer wears the urine pad 12 of this embodiment and the urine pad 12 is drawn in the width direction by the movement of the leg as shown in FIG. 7 , the absorber 21 has the bent portion 21a as the top. It bends in the shape of a mountain so as to protrude toward the crotch. By bending in this manner, for example, when the wearer is a woman, the bent portion 21a can be located near the urethral opening, and the other portion can have a crotch and a gap. As a result, the fit of the urine pad 12 in the crotch region is improved, and the contact area with the skin can be suppressed, so that the urine pad 12 can maintain a smooth feeling even after the body fluid is absorbed. In addition, since the width W _C of the narrow portion 21c of the absorber 21 corresponding to the crotch 12C of the urine pad 12 is narrow, the absorber 21 does not hold even if both legs are brought close.

In addition, the portions of the back sheet 19 and the top sheet 20 extending from the width direction edge of the narrow portion 21 c of the absorbent body 21 are not joined to the side sheet 22 and the absorbent body 21 does not exist. Region 12a is formed. Therefore, the free region 12a is also pulled up by being pulled up by the solid gathers 24g due to the expansion and contraction of the rubber-like elastic member 24. As a result, the rise height of the standing gathers 24g near the narrow portion 21c of the absorber 21 is increased with a length L ₁ of the free area 12a of the urine pad 12, the end of the standing gathers 24g, i.e., the side The free end 22a of the sheet 22 is positioned closer to the skin of the wearer than the ridge of the bent portion 21a. As the solid gathers 24g portion of the side sheet 22 rises in this manner, the crotch 12C of the urine pad 12 has a W-shaped cross section as shown in FIGS. 7 and 8 . The distance W _C / 2 from the ridge (apex) of the central bent portion 21a to the side end of the absorber 21 and the distance L ₂ from the side end of the absorber 21 to the free end 22a of the side sheet 22 are In comparison, L ₂ has a longer relationship than W _C / 2. Thus, when the portion of the three-dimensional gather 24g of the side sheet 22 rises high, the portion of the three-dimensional gather 24g securely adheres to the crotch of the wearer, and the space where the absorber 21 is located is made a closed space. The solid gathers 24g having a high height firmly hold the body fluid such as urine firmly and prevent the leakage to the outside.

  Moreover, since the absorber 21 is located only at the central peak portion in the W shape and the absorber 21 is not located at the rising portions on both sides, the overlapping of the absorbers 21 can be made only at the peak portion, There is no triple or quadruple overlap of the body 21 and there is no increase in thickness.

Thus, in the crotch 12C of the urine pad 12, a narrow portion 21c having a narrower width of the absorber 21 than the other portions is provided, and the width W _C of the narrow portion 21c is about the width of the crotch of the wearer By doing this, the absorbent body 21 does not get tired even in the crotch of the wearer, and even if the urine pad 12 swells by sucking the body fluid, the absorbent body 21 is suppressed from overlapping in the crotch area, and discomfort due to wearing Can be reduced.

The amount of the absorbent 21 in the crotch 12C is reduced due to the presence of the narrow portion 21c , so the amount of the superabsorbent polymer corresponds to the front 12F and the rear 12R in order to absorb a large amount of body fluid. It may be more than. In this case, the rigidity of the narrow portion 21c of the absorber 21 may be increased compared to other portions, but the absorber area itself in the crotch 12C is smaller than the absorber area in the front 12F and the rear 12R. The sense of stiffness does not matter so much because it is folded in half at the central bent portion 21a.

  Further, a bent portion 21a is provided at the center of the crotch portion 12C of the urine pad 12, and the bent portion 21a is bent preferentially even when the urine pad 12 is broken by the movement of the leg such as pulling of the leg of the wearer. Thereby, the center of the urine pad 12 is bent so as to protrude toward the skin. By this deformation, the top of the bent portion 21a comes in contact with the crotch while the other part can form a gap with the skin, so the surface where the urine pad 12 contacts with the skin and gives pressure is minimized. Suppress pleasure.

  In addition, the side sheet 22 located in the crotch 12C can stand up high by the solid gather 24g because the absorber 21 is narrow, and it firmly adheres to the wearer's inguinal region, causing leakage of body fluid. You can prevent. Further, in the crotch 12C, the urine pad 12 is deformed in a W-shaped cross section, but the absorber 21 itself is only a portion of a central mountain fold due to the fold 21a, and a portion rising from valley breaks on both sides is a side sheet 22 and back sheet 19 only. For this reason, the overlapping of the absorbers 21 is thin only in the width direction and is easy to fit in the crotch only at the portion of the central mountain fold due to the fold 21a.

  In addition, since the portions rising from the valley breaks on both sides are only the sheet members of the side sheet 22, the back sheet 19, and the top sheet 20, compared to the conventional one in which the absorber 21 is also folded by the valley breaks on both sides. Soft and easy to follow the movement of the legs. Therefore, the solid gather 24g portion is separated from the groin of the wearer, and there is no gap.

  Moreover, since the part which stands up by the solid gathers 24g is high, the effect of blocking body fluid is high.

In addition, it is also possible to form the absorber 21 by the pulp of one or more layers, and the structure of the multiple layers which used the absorbent sheet which does not contain a pulp in the said pulp layer may be sufficient. In this case, the absorbent sheet containing no pulp may not have the narrow portion 21c, and the regions of the front, crotch and back may be formed to have the same width. Since the absorbent sheet containing no pulp is soft, when the urine pad 12 bends in the crotch, it is pulled up by the standing of the solid gather 24 g and stands up in the same manner as the back sheet 19. Therefore, the urine pad 12 has a W-shaped deformation similar to that of the present embodiment.

In addition, the crotch 12C of the urine pad 12 is easily deformed in a W shape, and in order to maintain this deformed state during wearing, it is a valley broken part and this is one of the places where the load of the wearer is concentrated and added. The left and right ends of a narrow portion 21c of a certain absorbent body 21 may be press-processed to increase the rigidity more than the other portions of the absorbent body 21. Further, the deformation shape of the crotch 12C of the urine pad 12 is not limited to the W shape, and for example, the urine pad 12 is deformed in the direction in which both widthwise end portions of the back sheet 19 approach each other with the widthwise middle portion as a boundary. Then, both ends in the width direction of the back sheet 19 may be adhered, and this deformed state may be maintained.

  In addition, although this embodiment demonstrated the urine pad to which this invention was applied, this invention is applicable not only to a urine pad but other absorbent articles, such as a tape-type diaper and a pants-type diaper.
