Description

The present invention relates to an absorbent article mainly used for sanitary napkins, vaginal discharge sheets, incontinence pads, toiletries, etc. Specifically, the present invention relates to an absorbent article mainly used for sanitary napkins, vaginal discharge sheets, incontinence pads, toiletries, etc. The present invention relates to an absorbent article in which the position of the side edge portion can be recognized.

Conventionally, as the absorbent article, cotton-like pulp or the like has been used between a liquid-impermeable 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. It is known that an absorbent body consisting of the above is interposed, and an anti-slip adhesive layer is provided on the outer surface (underwear contact surface) of the back sheet to secure the undergarment.

To take out an absorbent article that has been folded into multiple pieces in the front-rear direction and put it on underwear, first place the absorbent article's body fluid discharge area corresponding to the crotch part of the underwear and fix it. The procedure is to fix the front part and the back part, which have been lifted up due to the folding tendency during individual packaging, to the underwear by pressing them with your hands from the skin-contacting side.

When holding the raised front and rear parts of an absorbent article with your hands, the wearer should hold the front and rear ends of the absorbent article as much as possible, because for hygiene reasons, you do not want to touch the skin-contacting surface of the absorbent article with your hands. I often held it with my hands. However, even if you press the area outside the area where the anti-slip adhesive layer is placed with your hand, it cannot be fixed to the underwear, so you have to change the area and repeat the process several times. The contact surface has to be touched over a wide area with the hands, which poses a hygiene problem, and there are other problems, such as insufficient fixation to the underwear, which tends to cause misalignment during wear, and the time it takes to put it on.

In recent years, various types of absorbent articles have been proposed that are provided with marks for attaching or removing absorbent articles. For example, Patent Document 1 listed below discloses that an index marker is provided in the crotch part of underwear for accurately locating an absorbent article, and Patent Document 2 listed below discloses the position of a non-adhesive area of a backsheet. Disclosed are visual indicators for indicating.

However, in Patent Documents 1 and 2, the positions of the front and rear ends of the anti-slip adhesive layer are not recognized from the skin-contacting surface side of the absorbent article, and the above-mentioned problem is not solved. There wasn't.

Therefore, the main object of the present invention is to be able to visually recognize the position of the front and rear ends of the anti-slip adhesive layer from the skin-contacting side of the absorbent article, maintain a sanitary condition, and securely fix it to underwear. To provide an absorbent article that can be worn easily and quickly.

In order to solve the above problems, the present invention according to claim 1 includes an absorbent body, a top sheet disposed on the skin contacting surface side of the absorbent body, and a surface sheet disposed on the non-skin contacting surface side of the absorbent body. In an absorbent article comprising a back sheet,
An anti-slip adhesive layer for fixing the absorbent article to underwear is provided on the non-skin contact surface of the main body portion in which the absorbent material is interposed between the top sheet and the back sheet, along the longitudinal direction and the width direction. There are multiple rows spaced apart ,

Embodiments of the present invention will be described in detail below with reference to the drawings.

[Basic structure of sanitary napkin 1]
As shown in FIGS. 1 to 3, the sanitary napkin 1 according to the present invention includes a liquid-impermeable back sheet 2 made of a polyethylene sheet, etc. ), an absorbent body 4 made of cotton-like pulp or synthetic pulp interposed between these two sheets 2 and 3, and both sides on the skin contact side. and side nonwoven fabrics 7, 7 provided over almost the entire length in the longitudinal direction, and around the absorbent body 4, the outer edges of the back sheet 2 and top sheet 3 are formed at the upper and lower edges thereof. The back sheet 2 and the side nonwoven fabric 7 are joined by a joining means such as hot melt adhesive, heat sealing, ultrasonic sealing, etc., and the back sheet 2 and the side nonwoven fabric 7 extend laterally beyond the absorber 4 at both side edges thereof. The flap portion is formed by joining using an adhesive such as hot melt, heat sealing, ultrasonic sealing, or other joining means. In the illustrated example, in order to maintain the shape of the absorbent body 4 and improve its diffusivity, the absorbent body 4 is surrounded by an enveloping sheet 5 made of crepe paper or nonwoven fabric. It does not need to be provided. Further, a second sheet made of a hydrophilic nonwoven fabric or the like having substantially the same shape as the top sheet 3 may be provided adjacent to the non-skin side of the top sheet 3.

Hereinafter, the structure of the sanitary napkin 1 will be explained in more detail.
For the back sheet 2, a sheet material such as polyethylene that has at least water-blocking properties is used, but from the viewpoint of preventing stuffiness, it is desirable to use a sheet material that has moisture permeability. This water-blocking and moisture-permeable sheet material is made by melt-kneading an inorganic filler into an olefin resin such as polyethylene or polypropylene, forming a sheet, and then stretching the sheet in a uniaxial or biaxial direction. A sheet is preferably used. On the non-skin contacting surface (outer surface) of the back sheet 2, there is one or more anti-slip adhesive layers 9, 9 in the illustrated example, three strips along the napkin longitudinal direction and spaced apart in the napkin width direction. is formed so that the sanitary napkin 1 is fixed to underwear when worn on the body. As the back sheet 2, a polylaminated nonwoven fabric made by laminating a plastic film and a nonwoven fabric may be used.

Next, as the top sheet 3, a perforated or non-perforated nonwoven fabric, a porous plastic sheet, or the like is preferably used. The material fibers constituting the non-woven fabric include synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters, and polyamides, recycled fibers such as rayon and cupro, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a spunlace method, a spunbond method, a melt blown method, or a needle punch method can be used. When a large number of through holes are formed in the top sheet 3, body fluids are quickly absorbed, resulting in excellent dry touch properties. The fibers of the nonwoven fabric may be either long fibers or short fibers, but it is preferable to use short fibers to give the texture of toweling. Further, in order to facilitate embossing, it is preferable to use olefin fibers such as polyethylene or polypropylene having a relatively low melting point. Further, composite fibers such as core-sheath type fibers, side-by-side type fibers, and split type fibers, which have a core of fibers with a high melting point and a sheath of fibers with a low melting point, can also be suitably used.

On the other hand, on the skin-contacting surface of the top sheet 3, compressed grooves 6 are formed in an appropriate pattern to be depressed toward the non-skin side. In the embodiment shown in FIG. 1, a compression groove 6 is formed to annularly surround the body fluid discharge portion corresponding region H, and ribbon-shaped compression grooves 6 are formed at the front and rear sides, respectively.

The absorbent body 4 interposed between the back sheet 2 and the top sheet 3 is made of, for example, fluff-like pulp and a water-absorbing polymer. The water-absorbing polymer is mixed into the pulp constituting the absorbent body, for example, in the form of granular powder. Examples of the pulp include chemical pulps obtained from wood, cellulose fibers such as dissolving pulp, and those made of artificial cellulose fibers such as rayon and acetate. Softwood pulps with longer fiber lengths have better functionality and properties than hardwood pulps. It is suitable for use in terms of price. When providing the covering sheet 5 that surrounds the absorbent body 4 as in this example, the covering sheet 5 is interposed between the top sheet 3 and the absorbent body 4, and is made of crepe paper or the like. The encapsulant sheet 5, which has excellent absorbency, allows bodily fluids to diffuse quickly and prevents menstrual blood from flowing back.

The absorbent body 4 may be mixed with synthetic fibers. The synthetic fibers can be, for example, polyolefins such as polyethylene or polypropylene, polyesters such as polyethylene terephthalate or polybutylene terephthalate, polyamides such as nylon, and copolymers of these. A mixture may also be used. Further, composite fibers such as core-sheath type fibers, side-by-side type fibers, split type fibers, etc., which have a core of fibers with a high melting point and a sheath of fibers with a low melting point, can also be used. In the case of hydrophobic fibers, it is desirable that the synthetic fibers be surface-treated with a hydrophilic agent so that they have an affinity for body fluids.

In the illustrated example, the width of the top sheet 3 is slightly longer than the width of the absorbent core 4, as shown in the cross-sectional views of FIGS. The outer side is a side nonwoven fabric 7 different from the top sheet 3, specifically, an appropriate repellent fabric depending on the purpose of preventing menstrual blood, vaginal discharge, etc. from penetrating, or increasing the texture. A side nonwoven fabric 7 made of a nonwoven fabric material subjected to water treatment or hydrophilic treatment is provided. For example, if you are focusing on functions such as preventing urine and vaginal discharge from penetrating or improving the texture, use water-repellent nonwovens coated with silicone-based, paraffin-based, or alkylchromic chloride-based water repellents. If absorbability of body fluids is important, it is desirable to use a method in which compounds with hydrophilic groups, such as oxidation products of polyethylene glycol, are coexisting and polymerized in the manufacturing process of synthetic fibers, or methods in which stannic chloride is used. Synthetic fibers are treated with metal salts to partially dissolve and make the surface porous, and synthetic fibers are made swollen or porous by depositing metal hydroxide, and hydrophilicity is imparted by applying capillary phenomenon. It is preferable to use The side nonwoven fabric 7 may be made of natural fibers, synthetic fibers, recycled fibers, or the like and formed by an appropriate processing method, but is preferably made of a material with a reduced basis weight to provide breathability. It is better to use non-woven fabric.

As shown in FIGS. 2 and 3, the side nonwoven fabric 7 is bonded with an adhesive such as hot melt from a predetermined inner position to the outer edge of the back sheet 2 at a portion outside the middle portion in the width direction. The laminated sheet portions of the side nonwoven fabric 7 and the back sheet 2 form flap portions on both sides of the absorbent body 4 in which the absorbent body 4 is not interposed. Although not shown, the flap portion may form a pair of left and right wing-shaped flaps at the side portion of the absorbent body that approximately corresponds to the region H corresponding to the body fluid discharge portion. Each of the wing-shaped flaps is provided with an adhesive layer on the outer surface side, and when attached to the underwear, the wing-shaped flaps are folded back to the opposite side at the folding line position of the base end and secured by wrapping around the crotch part of the underwear. can do.

On the other hand, on the inner side of the side nonwoven fabric 7, as shown in FIG. One or more (in the illustrated example, two) filament-like elastic stretchable members 8, 8 are arranged at appropriate positions, and the double sheet portion is erected on the surface side by the contraction force of the three-dimensional gathers G. , G are formed.

As shown in FIG. 1, the non-skin contact surface (outer surface of the back sheet 2) of the main body portion in which the absorbent body 4 is interposed between the top sheet 3 and the back sheet 2 is provided for fixing to underwear. A plurality of anti-slip adhesive layers 9, 9, 9, . These anti-slip adhesive layers 9, 9... are removably covered with a release sheet (not shown) when the sanitary napkin 1 is individually packaged.

[Mark]
In the present sanitary napkin 1, as shown in FIG. 1, the marks 10, 10, . It is provided at a position that is visible from the skin contact side. More specifically, the marks 10, 10 indicating the front end of the anti-slip adhesive layer 9 are located on the front side of the sanitary napkin 1 and are visible from the skin-contacting side of the sanitary napkin 1. Marks 10, 10 indicating the rear end of the anti-slip adhesive layer 9 are provided on the rear side of the sanitary napkin 1 and are visible from the skin-contacting side of the sanitary napkin 1. located at the location.

As mentioned above, the anti-slip adhesive layer 9 is provided on the non-skin contact surface (underwear contact surface) of the main body portion where the absorbent body 4 is interposed, so that the sanitary napkin 1 does not come into contact with the skin. From the side, it is impossible to see through it. Therefore, in this sanitary napkin 1, by providing the marks 10 that are visible from the skin-contacting surface side, the wearer can move from the skin-contacting surface side of the sanitary napkin 1 to the front side of the anti-slip adhesive layer 9. The respective positions of the end portion and the rear end portion can be visually recognized. Since the positions of the front and rear ends of the anti-slip adhesive layer 9 can be recognized by the marks 10, when the sanitary napkin 1 is taken out of the individual package and put on underwear, body fluids in the sanitary napkin 1 can be recognized. After fixing the part including the discharge part corresponding area H to the crotch part of the underwear, the front part and the back part, which have been raised due to the folding tendency when individually packaged, are placed against the skin contacting surface of the sanitary napkin 1. With minimal contact, the front and rear ends of the anti-slip adhesive layer 9 can be held by hand to be fixed to the underwear. Therefore, the skin-contacting surface of the sanitary napkin 1 can be maintained in a sanitary condition without repeatedly touching the skin-contacting surface with your hands, and the front and back portions of the sanitary napkin 1 can be kept in a sanitary state. It is securely fixed to underwear, making it difficult for it to shift while being worn, and making it possible to put it on quickly.

Hereinafter, the mark 10 will be explained in more detail.
It is preferable that the marks 10 are provided at positions corresponding to both sides of the area where the anti-slip adhesive layers 9, 9... are arranged. That is, among the three anti-slip adhesive layers 9 arranged along the longitudinal direction, the marks 10 are provided at positions corresponding to the outer sides in the width direction of the anti-slip adhesive layers 9 on both sides. ing. The anti-slip adhesive layer 9 is removed by pressing with a finger on the area S in the longitudinal direction where the marks 10 are arranged on both sides at the front end and the rear end of the anti-slip adhesive layer 9, respectively. The end can be securely fixed to underwear.

In the plan view of the sanitary napkin 1 shown in FIG. It may be arranged, and furthermore, it may be arranged at a position overlapping with the anti-slip adhesive layer 9. Preferably, in order to ensure that all the anti-slip adhesive layers 9 are pressed against the underwear by pressing the area S where the marks 10, 10 on both sides are arranged with fingers, the anti-slip adhesive layer 9... It is preferable to arrange them at a distance on the outside in the width direction.

The mark 10 is preferably applied by embossing, printing, or a combination thereof. The embossing forms a recessed portion on the non-skin side by squeezing from the skin contacting surface side. By applying the embossing, the embossed recesses are melted and solidified, giving the sanitary napkin 1 a different color tone compared to other areas when viewed from the outside, so that the position of the mark 10 can be clearly identified from the skin-contacting surface side. It becomes visible. The printing can be performed using any known printing method without any restrictions, and can be printed on any member or two or more members constituting the sanitary napkin 1 as long as it is visible from the skin-contacting side of the sanitary napkin 1. It may be applied. As a combination of embossing and printing, it is possible to print on an embossed part, or to emboss a printed part. Further, by applying the embossing, the transparency of the embossed recesses increases in a solidified state after being thermally melted. By coloring the back sheet 2 in a color different from that of the skin contacting surface, the color of the back sheet 2 may be seen through the embossed recesses.

The mark 10 may be provided at a position outside the absorbent body 4 in the width direction where it does not overlap with the absorbent body 4, as shown in FIG. 1, or at a position where it overlaps with the absorbent body 4, as shown in FIG. It may be provided. When provided at a position that does not overlap with the absorbent body 4, it may be placed so that there is a distance in the width direction between the absorbent body 4 and the side edge of the absorbent body 4, or as shown in FIG. It may be arranged close to the side edge of the absorbent core 4 so that there is no separation distance from the edge in the width direction. When disposed close to the side edges of the absorbent body 4, when the longitudinal region S where the marks 10, 10 are arranged on both sides is pressed by hand, almost the entire width of the absorbent body 4 can be pressed; This is preferable because the anti-slip adhesive layer 9 can be fixed to the underwear more reliably. On the other hand, as shown in FIG. 3, when the mark 10 is placed at a position overlapping the absorbent body 4, on both sides of the absorbent body 4 on which the side nonwoven fabrics 7 are laminated, there is a It is preferable to form an embossed concave portion recessed toward the non-skin side on the skin-contacting surface of the side nonwoven fabric 7 by squeezing. Thereby, the side nonwoven fabric 7 can be firmly fixed to the topsheet 3, and the side nonwoven fabric 7 can be prevented from peeling off at the front and rear ends.

In the example shown in FIG. 1, the planar shape of the mark 10 is a triangle pointing toward the center in the width direction, but as shown in FIG. (C) star shape, (D) cross shape, (E) heart shape, (F) arrow shape, etc. In addition, characters, figures, symbols, etc. may be formed. When forming a shape having a pointed portion toward the center in the width direction, such as a triangle or an arrow, the tip of the pointed portion is provided at a position that matches the end of the anti-slip adhesive layer 9 in the front and rear directions in the width direction. is preferable. This makes it possible to clearly grasp the end positions of the anti-slip adhesive layers 9 in the front-rear direction, and it becomes possible to reliably press the end positions of the anti-slip adhesive layers 9 in the front-rear direction with fingers.

The size of the mark 10 is determined based on the size of the sanitary napkin 1 as shown in FIG. Preferably, the length A in the longitudinal direction is formed to be a predetermined length. Specifically, the length A is preferably 3 to 30 mm, more preferably 10 to 20 mm. Further, the width B of the mark 10 is preferably 3 to 30 mm. As shown in FIG. 1, the region S in the longitudinal direction where the marks 10, 10 are arranged on both sides becomes the region against which the abdomen of the finger is pressed when fixing the front and rear ends of the sanitary napkin 1 to underwear. If the length of this area S in the longitudinal direction of the napkin is too large, it will become unclear which part of this area S should be pressed to securely fasten the napkin, and if it is too small, it will not be noticeable, which is undesirable.

[Finger pressing part]
In the present sanitary napkin 1, as shown in FIG. 5, the marks 10 are arranged on the skin-contacting surfaces corresponding to the front and rear ends of the anti-slip adhesive layer 9, respectively. It is desirable to provide a finger pressing part 11 in the longitudinal region S for the wearer to press his or her finger when fixing the front and rear ends of the sanitary napkin 1 to underwear. In other words, the front finger pressing part 11 is provided in the region S of the skin contact surface corresponding to the front end of the anti-slip adhesive layer 9, and the rear side of the anti-slip adhesive layer 9 A finger pressing portion 11 on the rear side is provided within the region S of the skin contact surface corresponding to the end portion. The finger pressing pressing portion 11 is a recessed portion recessed toward the non-skin side that is formed on the skin contacting surface of the topsheet 3 by squeezing from the skin contacting surface side of the topsheet 3 .

By providing the finger pressing compression part 11, the positions to press with the fingers when fixing the front and rear ends of the sanitary napkin 1 to the underwear become clearer, and the sanitary napkin 1 is even more firmly fixed to the underwear. become able to. In addition, when comparing the contact area between the finger and the surface of the sanitary napkin 1 when pressing the finger pressing part 11 with the abdomen of the finger, it is found that when pressing the flat part as shown in FIG. While almost the entire surface of the abdomen of the napkin contacts the surface of the napkin, as shown in FIG. The contact area between the abdomen of the patient and the surface of the sanitary napkin 1 is reduced. Therefore, the skin contact surface can be maintained in a more sanitary condition.

As shown in FIG. 5, the finger pressing part 11 is preferably formed in a linear shape extending in the width direction of the sanitary napkin 1 so as to cross all the anti-slip adhesive layers 9. As a result, all the anti-slip adhesive layers 9 can be firmly fixed to the underwear by placing the abdomen of the finger along the linearly formed finger-pressing compression part 11. When the finger-pressing compressing portion 11 is formed in a linear shape, it is preferable that one finger-pressing compressing portion 11 is provided within the region S. If two or more are provided, it is not preferable because it becomes unclear which pressing part should be pressed.

It is preferable that the finger-pressing pressing section 11 is arranged at a position that includes a region on the skin-contacting surface side corresponding to the front end and the rear end of the anti-slip adhesive layer 9, respectively. In other words, the finger pressing compression part 11 disposed in the front area S of the sanitary napkin 1 is disposed at a position that includes the area on the skin contact surface side corresponding to the front end of the anti-slip adhesive layer 9. The finger-pressing compressing part 11 arranged in the region S on the rear side of the sanitary napkin 1 is located at a position including a region on the skin-contacting surface side corresponding to the rear end of the anti-slip adhesive layer 9... It is located in In the embodiment shown in FIG. 5, the finger pressing compression part 11 is formed in a line that passes through the skin-contact surface side corresponding to the front end and the rear end of the anti-slip adhesive layer 9. It is formed. In the embodiment shown in FIG. 5, the front end and the rear end of the anti-slip adhesive layer 9 are arranged on a straight, almost straight line in the width direction of the sanitary napkin 1, so that the finger pressing part 11 is also formed by a straight line extending in the width direction of the sanitary napkin 1.

On the other hand, if the front end and the rear end of the anti-slip adhesive layer 9 are not on a straight line with respect to the width direction of the sanitary napkin 1, for example, as shown in FIG. When the front end and the rear end of the anti-slip adhesive layer 9 are located on the outer side in the longitudinal direction of the anti-slip adhesive layers 9, 9 disposed on both sides, as shown in the illustrated example, The compressed portion 11 bulges outward in the longitudinal direction at the center in the width direction so that the compressed portion 11 passes through the skin-contact surface side corresponding to the front end or the rear end of all the anti-slip adhesive layers 9. It is preferable to form it in a curved shape.

In this way, the planar shape of the finger-pressing pressing part 11 can be formed in various shapes according to the front end or the rear end of the anti-slip adhesive layer 9. However, it is preferable that the finger-pressing part 11 be provided only in the region S in the longitudinal direction where the marks 10, 10 are arranged on both sides, and should not be provided extending outward from the region S. It is preferable to do so. This allows the sanitary napkin 1 to be firmly fixed to the underwear while maintaining a sanitary condition without touching the outside of this area S with your hands when pressing your finger along the finger pressing compression part 11. It becomes like this. Therefore, as shown in FIG. 1, the ribbon-shaped compression grooves 6 provided at the front and rear sides are formed in an area including a longitudinal area S where the marks 10, 10 are arranged on both sides. , is not provided in accordance with the front end or the rear end of the anti-slip adhesive layer 9, and is provided extending outward from the region S, so it is not the finger pressing pressing part 11. .
