Description

  The present invention relates to absorbent articles such as sanitary napkins, panty liners, and incontinence pads for absorbing menstrual blood, vaginal discharge, etc., and more specifically, three-dimensional gathers formed on both sides of the surface of the absorbent article. Concerning structure.

  Conventionally, as an absorbent article such as a panty liner, sanitary napkin, incontinence pad, a liquid-impervious back sheet such as a polyethylene sheet or a polyethylene sheet-laminated nonwoven fabric, and a liquid-permeable top sheet such as a nonwoven fabric or a liquid-permeable plastic sheet There is known an intervening absorber made of cotton-like pulp or the like.

  Many improvements have been made to this type of absorbent article, and various ideas have been made. For example, in the absorbent article (night sanitary napkin 50) shown in FIGS. 10 and 11, a liquid-impervious back sheet 52 made of a polyethylene sheet or the like and a liquid-permeable top sheet that allows menstrual blood or the like to permeate quickly. 53, an absorbent body 54 made of cotton-like pulp or synthetic pulp interposed between the two sheets 52, 53, and a pair of left and right three-dimensional gathers BS, BS provided on both sides of the surface. In the periphery of the absorbent body 54, the outer edge portion of the liquid-impervious back sheet 52 and the liquid-permeable top sheet 53 is bonded at the front and rear end edges thereof by an adhesive such as hot melt or heat seal. The liquid-impermeable back sheet 52 which is joined by the means and extends laterally from the absorbent body 54 at both sides (side flap portions) and the three-dimensional gather BS are formed. The side nonwoven fabric 55 is bonded by an adhesive such as hot melt or an adhesive means such as heat seal, and a wing shape protruding laterally by a laminated sheet portion of the liquid-impermeable back sheet 52 and the side nonwoven fabric 55. The flaps W and W are formed, and the hip-hold flaps HF and HF are formed on the rear side of the flaps W and W. The three-dimensional gather BS is for blocking body fluid and preventing side leakage, and the wing-shaped flaps W and W are for fixing the sanitary napkin 50 tightly to shorts. The hip-hold flaps HF and HF are for preventing lateral displacement of the sanitary napkin 50 and body fluid leakage on the buttock side.

  The adhesive layers 57..., 58... Are respectively provided on the back surfaces of the wing-shaped flaps W and W and the hip-hold flaps HF and HF, and the sanitary napkin 50 is shown in FIG. As shown, the sanitary napkin 50 is applied locally, the wing-shaped flaps W, W protruding laterally are taken out from the underwear, folded at the fold lines RL, RL at the base end of the wing-shaped flap W, and the underwear 30 Attach it to the outer surface of the crotch part of the underwear while keeping the crotch part of the wrap around.

Examples of the sanitary napkin that have a pair of left and right three-dimensional gathers on both sides of the surface side include the following Patent Documents 1 to 5; among these sanitary napkins, As a three-dimensional gather in the napkin for use, what is formed over a relatively long range from the front side to the rear side of the napkin is shown.
JP 2004-358109 A Japanese Patent Laid-Open No. 2003-62008 JP 2001-95842 A JP 2002-656 A JP-A-64-68503

  However, the three-dimensional gathers shown in Patent Documents 1 to 5 are respectively formed on both sides corresponding to the body fluid discharge site. For example, when body fluid is discharged in the supine state at bedtime, The body fluid that once leaks to the side and then laterally leaks so as to diffuse to the side cannot be well blocked.

  In addition, the napkin is mounted in a state of being sandwiched between the body and shorts, and even if there is a difference in individual body shape, the napkin is mounted in close contact with the body due to its flexibility. When the three-dimensional gather is formed over a relatively long range like the three-dimensional gather shown, the curved shape in the longitudinal direction of the napkin becomes too large due to the three-dimensional gather, and depending on the body shape, the body can be well adapted to the body. As the three-dimensional gather formation section becomes longer, the contraction force of the elastic member must be set to a certain level, the elastic elastic member may give the skin a sense of incongruity, and the elastic elastic member may be retracted during manufacturing. There was a problem that it might occur.

  Therefore, the main problem of the present invention is that the body fluid that leaks sideways so as to diffuse once after flowing to the buttocks side is blocked, and the bending of the napkin in the longitudinal direction is caused by the elastic force of the elastic member arranged in the three-dimensional gather. The purpose is to prevent the shape from being over-regulated and being unable to follow the body.

As the present invention according to claim 1 for solving the above-mentioned problem, in an absorbent article in which an absorbent body is interposed between a liquid-permeable top sheet and a back sheet,
On the surface side of the absorbent article, a set of three-dimensional gather components provided in the longitudinal direction on both the left and right sides, and two sets of these three-dimensional gather components are provided, and one side of the three-dimensional gather components is a body fluid In the discharge part corresponding part, it was made to stand on the surface side by the contraction force by the elastic expansion and contraction member, and the three-dimensional gather component on the other side was made to stand on the surface side by the contraction force by the elastic expansion and contraction member in the part corresponding to the buttock side. A featured absorbent article is provided.

  In the present invention described in claim 1, two sets of three-dimensional gather components are provided on the surface side of the absorbent article, with one set of three-dimensional gather components provided on the left and right sides in the longitudinal direction. To do. The one-sided three-dimensional gather component is caused to stand on the surface side by the contraction force by the elastic expansion and contraction member at the body fluid discharge portion corresponding portion, and the other side three-dimensional gathering component is the contraction force by the elastic expansion and contraction member at the buttocks side corresponding portion It is intended to stand on the surface side.

  Therefore, the body fluid that flows laterally at the body fluid discharge site can be dammed by the three-dimensional gather on one side, and the body fluid that leaks laterally so as to diffuse once after flowing to the buttocks side is described above. Can be dammed by the three-dimensional gather. In addition, since the elastic elastic members for raising the three-dimensional gather function to stand up the barriers at the respective three-dimensional gather parts, the curved shape in the longitudinal direction of the napkin is caused by the elastic elastic force arranged in the three-dimensional gather. Can be prevented from being overly regulated by the body.

  Furthermore, since the contraction force of the elastic elastic member is sufficient for normal setting, the elastic elastic member may give the skin a sense of incongruity and can prevent the elastic elastic member from being pulled in during manufacturing.

  The absorbent article according to claim 1, wherein the standing range of the one-sided solid gathering component and the standing range of the other side three-dimensional gathering component are given an overlap margin as the present invention according to claim 2. Is provided.

  The present invention according to claim 2 is configured such that an overlapping margin is provided between the rising range of the one-sided solid gathering component and the standing range of the other-sided solid gathering component. If there is a section that does not have a barrier between the one-sided solid gather and the other-side solid gather, there is a concern about side leakage from the section. By providing a margin, it is possible to prevent side leakage in most sections in the longitudinal direction.

  As the present invention according to claim 3, the standing base point of the one-sided three-dimensional gathering component and the standing base point of the other-side three-dimensional gathering component are separated in the width direction of the absorbent article. 2. An absorbent article according to any one of 2 is provided.

  In the third aspect of the present invention, the standing base point of the one-sided three-dimensional gathering component and the standing base point of the other-side three-dimensional gathering component are separated in the width direction of the absorbent article. is there. By forming an interval (groove) between the standing base point of the adjacent one-sided solid gather and the other side three-dimensional gathering standing base point, the effect of preventing side leakage is enhanced.

  As the present invention according to claim 4, the contraction force of the elastic elastic member disposed on the other side three-dimensional gather component is more than the contraction force of the elastic elastic member disposed on the one side three-dimensional gather component. The absorbent article according to any one of claims 1 to 3, which is set to be relatively small.

  In the invention according to the fourth aspect, the contraction force of the elastic expansion / contraction member in the other side three-dimensional gather is set to be relatively smaller than the contraction force of the elastic expansion / contraction member in the one side three-dimensional gather. If the contraction force of the three-dimensional gather on the buttock side is set high, it is desirable to set the elastic expansion / contraction member to a relatively small value because the elastic elastic member tends to give the heel part a feeling of strangeness.

  As this invention which concerns on Claim 5, the said absorbent article is a night absorbent article which has the rear part flap extended outward on both sides of a rear part, The absorbent article in any one of Claims 1-4 is provided. Is done.

  The invention according to claim 5 applies the present invention to a night absorbent article having rear flaps extending outwardly on both sides of the rear. In particular, it is a night-time absorbent article that has a problem of side leakage on the rear side (the buttock side).

  As described above in detail, according to the present invention, it is possible to satisfactorily stop the body fluid that leaks laterally so as to diffuse once after flowing to the buttocks side, and by the elastic stretching force disposed in the three-dimensional gather. It is possible to prevent the curved shape in the longitudinal direction of the napkin from being restricted too much by being restricted. In addition, since the contraction force of the elastic elastic member is sufficient for normal setting, it is possible to prevent the elastic elastic member from giving an uncomfortable feeling to the skin and to prevent the elastic elastic member from being pulled in during manufacturing.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[Basic structure of sanitary napkin 1]
1 is a developed view of a sanitary napkin 1 according to a first embodiment of the present invention, FIG. 2 is a view taken along the line II-II in FIG. 1, and FIG. 3 is a view taken along the line III-III in FIG. 4 is a view taken along the line IV-IV in FIG.

The sanitary napkin 1 includes a liquid-impervious back sheet 2 made of a polyethylene sheet, a liquid-permeable top sheet 3 that allows permeation of menstrual blood, cages, and the like, and an intervening sheet between the sheets 2 and 3. Absorbent body 4 made of cotton-like pulp or synthetic pulp, etc., crepe paper 5 surrounding the absorbent body 4 for maintaining the shape and improving the diffusibility of the absorbent body 4, and a surface corresponding to the body fluid discharge site R1 Mainly from a pair of left and right front side gathers BS ₁ and BS ₁ provided on both sides of the side and a pair of left and right rear side gathers BS ₂ and BS ₂ provided on both sides of the rear side surface of the napkin 1 The outer periphery of the liquid-impervious backsheet 2 and the liquid-permeable topsheet 3 is formed of an adhesive such as hot melt, heat seal, etc. Are joined by wearing means and said liquid-impermeable back sheet 2 that extends laterally than the absorption body 4 at both side edge portions thereof, the three-dimensional gathers BS _1, to form a BS ₂ side nonwoven fabric 7 Are bonded by an adhesive such as hot melt or an adhesive means such as heat seal, and wing-like flaps W and W projecting sideways are formed by the laminated sheet portion of the liquid-impermeable back sheet 2 and the side nonwoven fabric 7. In addition, second wing-shaped flaps (rear flaps) W _B and W _B are formed in a portion located on the side of the buttock than this.

Hereinafter, the structure of the sanitary napkin 1 will be described in detail.
As the liquid-impervious backsheet 2, a sheet material having at least water shielding properties such as polyethylene is used. The water- and moisture-permeable sheet material is a microporous material obtained by melting and kneading an inorganic filler in an olefin-based resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. A sheet is preferably used. One or a plurality of adhesive layers (not shown) are formed on the non-use side (outer surface) of the liquid-impermeable back sheet 2 so as to fix the sanitary napkin 1 to the underwear when worn on the body. It has become. As the liquid-impermeable back sheet 2, a polylaminated nonwoven fabric in which a plastic film and a nonwoven fabric are laminated may be used.

  As the liquid-permeable top sheet 3, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. As the material fibers constituting the nonwoven fabric, in addition to olefins such as polyethylene or polypropylene, polyesters, polyamides, and other synthetic fibers, regenerated fibers such as rayon and cupra, and natural fibers such as cotton can be used. A nonwoven fabric obtained by an appropriate processing method such as a method, a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft. When a large number of through holes are formed in the liquid permeable top sheet 3, menstrual blood, venom, etc. (hereinafter collectively referred to as body fluid) are quickly absorbed, and the dry touch property is excellent. It will be a thing.

  The absorbent body 4 is not particularly limited as long as it can absorb and retain bodily fluids. Usually, a fluffy pulp mixed with a water-absorbing polymer powder is preferably used from the viewpoint of the absorption function and cost. The absorbent body 4 is preferably surrounded by crepe paper 5 to maintain its shape.

In the illustrated example, the width dimension of the liquid-permeable top sheet 3 is slightly longer than the width of the absorbent body 4 as shown in the cross-sectional views of FIGS. The three-dimensional gathers BS ₁ and BS ₂ are stopped, and the side non-woven fabric 7 different from the liquid-permeable top sheet 3, specifically, prevents menstrual blood, or the like from penetrating, or enhances the feeling of touch. Depending on the purpose, a nonwoven fabric material subjected to appropriate water repellent treatment or hydrophilic treatment is used. The side nonwoven fabric 7 can be made of natural fiber, synthetic fiber, regenerated fiber, or the like and formed by an appropriate processing method. Preferably, the side nonwoven fabric 7 eliminates the feeling of stickiness and prevents stuffiness. For this reason, it is preferable to use a non-woven fabric with reduced basis weight and air permeability. Specifically, it is desirable to use a nonwoven fabric prepared with a basis weight of 18 to 23 g / m ² , and silicon-based, paraffin-based, alkylchromic chloride-based water repellents, etc. to reliably prevent the passage of body fluids. A water repellent nonwoven fabric coated with is preferably used.

As shown in FIGS. 2 to 4, the side nonwoven fabric 7 extends from the inner side position of the absorbent body 4 to the outer edge of the liquid-impermeable back sheet 2 slightly beyond the absorbent body side edge from the width direction intermediate portion. Are bonded by an adhesive such as hot melt over the range of the above, and by the laminated sheet portion of the side nonwoven fabric 7 and the liquid-impermeable back sheet 2, a pair of left and right at the absorbent body side position substantially corresponding to the body fluid discharge portion. wing flaps W, to form a W, a second wing-shaped flaps W _B now to the buttocks side _position, to form a W _B. These wing-shaped flaps W, W and second wing-shaped flaps (rear flap) W _B, W, respectively on the outer surface side adhesive layer 12 of the _B ..., 13 ... comprises a, as shown in FIG. 12, against shorts 30 At the time of mounting, the wing-shaped flaps W, W are folded back to the opposite side at the position of the folding line RL, and are wound around the crotch portion of the shorts and fastened.

The front-side three-dimensional gather BS ₁ and the rear-side three-dimensional gather BS ₂ are formed by the inner side sheet portion of the side nonwoven fabric 7. The front-side three-dimensional gather BS ₁ is a three-dimensional gather that is formed on both sides corresponding to the body fluid discharge site R1 and prevents side leakage of body fluid by a standing barrier, and the rear-side three-dimensional gather BS ₂ It is a three-dimensional gather for damming body fluid that is formed on both sides of the side and leaks laterally so that it once flows to the buttock side and then diffuses to the side.

Specifically, as shown in FIGS. 2 to 4, two barriers (solid gathering components) are formed in which the inner side sheet portion of the side nonwoven fabric 7 is folded almost double over the entire length in the longitudinal direction. ing. The barrier 7B formed relatively inside is for forming the front side three-dimensional gather BS ₁ , and the barrier 7A formed relatively outside is used for forming the rear side three-dimensional gather BS _2. It is.

First, in the body fluid discharge site R1, as shown in FIG. 2, an elastic elastic member in which appropriate positions in both ends or in the longitudinal direction are fixed to the middle portion in the height direction inside the double sheet of the inner barrier 7B. 15 and a plurality of, in the illustrated example, two elastic elastic members 14 and 14 are arranged on the upper portion of the elastic elastic member 15 in a state where both ends or appropriate positions in the longitudinal direction are fixed. The inner barrier 7B is erected on the surface side in the BS ₁ section shown in FIG. 1 by the contraction force of the elastic elastic members 14 and 15. In this case, the double sheet portion of the inner barrier 7B is located on the top sheet 3 side at the front and rear end portions of the napkin, with the region portions 19 and 20 indicated by hatching in FIG. By bonding, as shown in FIG. 2, the front-side three-dimensional gather BS ₁ has a pocket in which an opening is directed inwardly in a cross-sectional shape with the arrangement site of the elastic elastic member 15 as a bending point. While forming P, it stands on the surface side. In contrast, the outer barrier 7A is folded outward and bonded to the surface of the side nonwoven fabric 7 of the side flap by a hot melt adhesive or the like (shaded area 21).

On the other hand, as shown in FIG. 4, one or more elastic elastic members 16 in the illustrated example are disposed inside the double sheet of the outer barrier 7A on the collar side, and this elastic elastic member The outer barrier 7A stands up on the surface side in the BS ₂ section shown in FIG. On the other hand, the inner barrier 7B is bonded to the top sheet 3 in a state where the inner barrier 7B is folded and laminated in a Z-shaped section.

Incidentally, in the above the boundary portion between the front side three-dimensional gather BS ₁ and the rear-side three-dimensional gathers BS _2, as shown in FIG. 3, the top sheet in a state in which the inner barrier 7B are stacked folded section Z-shaped The outer barrier 7A is also folded outward and bonded to the surface of the side nonwoven fabric 7 of the side flap with a hot melt adhesive or the like.

By the way, as shown in FIG. 5, the standing range of the front side three-dimensional gather BS _{1 and} the standing range of the rear side three-dimensional gather BS ₂ may have an overlap margin in the longitudinal direction. . In the overlap margin section, as shown in the cross-sectional view of FIG. 6, the inner barrier 7B stands on the surface side and the outer barrier 7A also stands on the surface side. Lateral leakage can be reliably prevented in this section.

Moreover, since the compression force by the elastic expansion / contraction member 16 tends to give a sense of incongruity on the buttock side, the contraction force of the elastic expansion / contraction member 16 in the rear side three-dimensional gather BS ₂ is the elastic expansion / contraction member 14 in the front side three-dimensional gather BS ₁ . It is better to set it relatively smaller than 15 contraction force.

  As the elastic elastic members 14 to 16, materials such as styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicon, polyester and the like that are usually used can be used.

[Another formation example of the three-dimensional gather BS ₁ and BS ₂ ]
(1) In the above embodiment, the front-side three-dimensional gather BS ₁ is erected on the surface side while forming a pocket P with an opening inward in a cross-sectional shape, and the rear-side three-dimensional gather BS ₂ is upright. Although it was formed as a wall-shaped barrier, as shown in FIG. 7, two barriers 7A and 7B are formed by using the non-woven fabric 7 as a base point S with substantially the same point on the side edge of the absorbent body, and the body fluid discharge portion R1 In the corresponding part, as shown in FIG. 7 (A), in the double sheet, an elastic stretchable member 15 having both ends or an appropriate position in the longitudinal direction fixed to the middle in the height direction is disposed. A plurality of, in the illustrated example, two elastic elastic members 14, 14 are disposed in the upper portion of the elastic elastic member 15 in a state where both ends or appropriate positions in the longitudinal direction are fixed, and the inner barrier 7 </ b> B has a cross-sectional shape. Pocket P with an opening facing inward Formed while erecting on the surface side while the outer barrier 7A adhered in the folded state.

On the other hand, as shown in FIG. 7 (B), on the heel part side, an elastic elastic member 18 having both ends or appropriate positions in the longitudinal direction fixed to the middle part in the height direction is disposed in the double sheet. A plurality of, in the illustrated example, two elastic elastic members 17 and 17 are disposed on the upper portion of the elastic elastic member 18 in a state where both ends or appropriate positions in the longitudinal direction are fixed, and the outer barrier 7A is cross-sectioned. While forming a pocket P with an opening facing inward in a square shape, the inner barrier 7B is folded and adhered to the inner surface of the outer barrier 7A in a folded state, thereby allowing the front side Both the three-dimensional gather BS ₁ and the rear-side three-dimensional gather BS ₂ can be erected on the surface side while forming a pocket P having an opening inward in a cross-sectional shape.
(2) The three-dimensional gathering mode shown in FIG. 8 is an example in which the outer barrier 7A is formed from the substantially outer bending point position of the inner barrier 7B formed in a cross-sectional shape. As shown in FIG. 8A, in the front side three-dimensional gather BS ₁ forming member, the outer barrier 7A is bonded to the outer surface side of the inner barrier 7B, and the inner barrier 7B is raised by the elastic elastic members 22, 22. The front side three-dimensional gather BS ₁ is formed, and, as shown in FIG. 8 (B), at the rear side three-dimensional gather BS ₂ formation site, the lower part from the bending point of the inner barrier 7B is on the top sheet 3 side. as well as adhesive, to adhere the upper portion than the bending point of the inner barrier 7B so as to laminate on the upper surface thereof, to form the rear side standing gather BS ₂ by causing the outer barrier 7A portion erected by resilient and elastic members 23, 23 I am doing so.
(3) The solid gathering mode shown in FIG. 9 is an example in which the standing base point of the inner barrier 7B and the standing base point of the outer barrier 7A are separated by a distance D in the width direction of the napkin. In the front side three-dimensional gather BS ₁ formation site, the inner barrier 7B is erected by the elastic elastic members 24, 24, while the outer barrier 7A is bonded to the surface of the side nonwoven fabric 7 of the folded side flaps with a hot melt adhesive or the like. 9B, in the rear side three-dimensional gather BS ₂ formation site, the inner barrier 7B is folded inward and bonded to the top sheet 3 side, while the outer barrier 7A is attached to the elastic elastic member 25, 25 so as to stand on the surface side.
