Description

Absorbent articles

  The present invention relates to an absorbent article such as a pants-type disposable diaper main body and an auxiliary absorbent article.

Disposable disposable diapers are well known as absorbent articles for body fluids such as urine.
Although this paper diaper is worn on the body differently depending on the type of product, it is used between the liquid-permeable top sheet and the liquid-impermeable back sheet to absorb and retain body fluids such as urine and feces. This is common in that it has a structure in which an absorber is interposed. (See Patent Documents 1 to 3).
In recent years, for the purpose of increasing the amount of absorbed body fluid, a new wearing mode has been adopted in which auxiliary absorbent articles such as an absorption pad and an incontinence pad are used in combination. (See Patent Documents 4 to 5).
And in order to improve the convenience of such a new wearing mode, the present applicant attaches both the diaper body and the auxiliary absorbent article so that the auxiliary absorbent article can be attached to an appropriate position of the diaper body. An application was made for an absorbent article provided with a location mark (see Patent Document 6).

The invention described in this cited document 6 has improved many of the attachment of the auxiliary absorbent article to the wrong position, but the attachment position of the auxiliary absorbent article is almost unambiguous and there is almost no room for adjustment. It was impossible to select various mounting positions according to the gender and lifestyle of the person.
Moreover, even if the invention of Cited Document 6 is used, there is a case where it is not completely mounted at an appropriate position.
The present inventors investigated such mounting mistakes, and found that this occurred particularly when using an auxiliary absorbent article for a pant-type diaper body, particularly a diaper body having a so-called standing cuff. .
And the cause of this is that the pants-type diaper body is folded and compactly packaged so as to enhance the commercial product, and it is difficult to judge the position properly because it is folded. In many cases, it is caused when the mark is in a position that is difficult to visually recognize due to standing or lying down of the cuff.
In particular, in the case of a pants-type diaper body, when the wearer attaches the auxiliary absorbent article, the diaper body is fixed with his / her legs while the diaper body is held to about the knee, and the inside of the diaper body is viewed from above. The operation of attaching the auxiliary absorbent article to the inner surface of the diaper is often taken, and in the case of adopting such a mounting method, there is a case where the mark cannot be visually recognized in the invention of the cited document 6 and cannot be sufficiently dealt with.
Therefore, the present invention is capable of reliably attaching the auxiliary absorbent article to a pant-type diaper body, particularly a diaper body having a standing cuff, in an appropriate position. The task is to improve convenience.

In particular, in the case of this embodiment, the leg opening side end of the side joint corresponds to both ends of the leg periphery edge EL.
Moreover, the front-rear direction of the diaper main body in the present invention is the front-rear body direction based on the unfolded state shown in FIG. 1, and the width direction is a direction perpendicular to this.

The exterior sheet 11 of this embodiment has a laminated structure in which appropriate elastic elastic members such as a leg elastic elastic member 20, a waist elastic elastic member 21, a waist elastic elastic member 22 and the like are arranged between two layers of nonwoven fabric sheets 11s and 11s. Have.
The sheet material can be appropriately selected from non-woven sheets as well as sheet materials used as a known diaper exterior, and the number of sheets stacked can also be set appropriately. The arrangement form of the elastic elastic members is not limited to the form shown in the drawing.

  Various elastic elastic members 20 to 22 are typically made of rubber thread. As the thread rubber, those made of synthetic rubber or natural rubber and those mainly composed of natural rubber are suitable. In addition to the rubber thread, a material having rubber elasticity, which is formed (molded) into a thread shape, a string shape, a belt shape, a net shape, a foam shape, or the like, including a generally well-known elastomer resin can be used. For example, materials such as styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicon, and polyester can be used.

The absorbent body 3 is arranged so as to extend from the front body to the back body through the crotch according to a known pants-type diaper. The exterior body 1 is bonded by a known appropriate method such as a hot melt adhesive.
The structure of the absorbent body 3 is a layered structure in which an absorbent core 33 is disposed between a liquid-permeable top sheet 31 and a liquid-impervious back sheet 32, and the longitudinal direction (front and back) on the skin contact surface side. So-called standing cuffs (also referred to as barrier cuffs) 14, 14 standing along the longitudinal direction on the skin side by lifting elastic elastic members 23, 23, etc. provided along the direction).

The standing cuffs 14 and 14 are folded in such a manner that the standing sheets 40 and 40 are folded shortly on the inner surface side, and the two elastic elastic members 23 and 23 for lifting are fixed by a hot melt adhesive (not shown) or the like. Has a wrapped tip.
Furthermore, the other end side of the standing sheets 40, 40 is folded back to the liquid-impervious back sheet side at the bonding edge 14s between the liquid-permeable surface sheet 31 and the liquid-impervious back sheet 32, and impermeable from the bonding edge. It extends toward the center in the width direction of the liquid back sheet. And it adheres with the non-peeling hot-melt-adhesive etc. suitably with respect to the said liquid-impermeable back sheet from the joining edge.
Therefore, the rising end line 14s of the standing cuff 14 is an adhesive edge between the joining edge or the liquid-impervious back sheet and the exterior sheet.
In addition, the front-rear direction end portions of the upright sheets 40, 40 are applied to the article in a state where the front end of the free part is directed to the center side in the width direction of the article, specifically, a hot melt adhesive not illustrated on the outer surface of the liquid-permeable surface sheet, etc. It is fixed by and is urged to stand on the use surface side.
Further, the standing cuffs 14 and 14 are not limited to this example, and can have a form having a sticking start end in the form of a liquid-permeable surface sheet.

On the other hand, it is desirable that the standing sheet 40 forming the standing cuffs 14, 14 is not liquid-permeable but liquid-impermeable or hydrophobic. Further, the liquid-permeable sheet may be repelled by silicon treatment or the like. In addition, the concrete raw material of the sheet | seat for standing can use the thing similar to the raw material of the above-mentioned liquid-permeable surface sheet 31 or the liquid-impermeable back sheet 32. FIG.
Further, as the material of the lifting elastic stretchable member 23, thread-like elastic rubber made of styrene rubber, olefin rubber, urethane rubber, polyurethane, polystyrene or the like is preferably used. The lifting elastic elastic member has a thickness of 400 dtex or more, particularly preferably 500 to 1200 dtex, and is fixed to the standing sheet in a stretched state of 150 to 300%, particularly preferably 200 to 250%.

On the other hand, the diaper main body X1 of the present embodiment is characteristically provided with mounting positioning marks 50, 50 serving as a guide for the mounting position of the absorbent pad (auxiliary absorbent article) on the use surface side of the absorber side edge. . In the example shown in FIG. 1, the mounting positioning marks 50, 50 are formed on a liquid-permeable top sheet.
In the example shown in FIG. 4, the mounting positioning marks 50, 50 are provided on the standing cuffs 14, 14. In addition, in the example of FIG. 4, although it provided in the side surface which does not face a liquid-permeable surface sheet at the time of standing cuffs falling down, the surface which faces a liquid-permeable surface sheet at the time of standing cuffs lying down may be sufficient.
The mounting positioning marks 50, 50 are, for example, patterns, letters, numbers, designs, figures, etc., and ink or colored hot melt adhesive is applied to the positions by various printing machines such as inkjet and offset. Can do. It can also be formed by cutting a male or female material of a mechanical fastener, paper such as colored or printed thin paper into an appropriate pattern, design, or figure and adhering it to an appropriate position.

As a specific example of the shape of the mounting positioning marks 50, 50, a straight line shape figure in the longitudinal direction shown in FIG. In the example shown in FIG. 4, as a more preferable example, a substantially U-shaped bracket having a certain length in the longitudinal direction, with the standing tip edge 14 e side being the opening side at the same position in the front-rear direction of the left and right standing cuffs 14, 14. These characters are given by inkjet printing.
With these shapes, reliable positioning is achieved by an intuitive operation of matching a mounting positioning mark to be given to an absorption pad (auxiliary absorbent article) described later with a linear range or a U-shaped opening range. Of course, the mounting positioning marks 50 and 50 are not limited to these figures, and can be suitably seen figures.

If the mounting positioning marks 50 and 50 are the shape examples shown in FIGS. 1 and 4, the size depends on the size of the diaper main body, but the width is 2 to 10 mm and the length in the front-rear direction is about 30 to 60 mm. It is good to do.
In the present invention, the front-rear direction length of the mounting positioning mark 50 and 50, longer than mark 80, 80 for positioning to be described later. There is a certain margin in the range in which the absorbent pad Y1 is matched with the diaper main body X1, and it becomes easy to match the mark intuitively without becoming nervous, which is convenient.

On the other hand, the position in the front-rear direction of the mounting positioning marks 50, 50 is not particularly limited, but preferably the range includes a range of 15 to 35 mm in the front-rear direction from the front-rear center (groin C) of the diaper body X1. Good. In the example of FIGS. 1 and 4, in particular, it is arranged in a range of 15 to 35 mm in the front-rear direction across the center in the front-rear direction (longitudinal direction), that is, the crotch C position.
Although the position in the width direction depends on the size of the diaper main body, it is located in the range of 10 to 40 mm from the absorber side edge (the joining edge of the liquid-permeable surface sheet and the liquid-impermeable back sheet in the example of FIG. 1). It is good to do. When it is provided on the standing cuff, it depends on the standing length. As the position on the standing cuffs, the standing cuffs 14 and 14 are preferably located within a range of about 5 to 15 mm from the tip edge 14e. If it exceeds 15 mm, the mark becomes difficult to visually recognize due to the standing cuff 14 standing up.

The mounting positioning marks 50, 50 can be configured to have a leak sensor function that changes color when contacted with urine or the like. A known technique can be used for the leak sensor function based on such a color change.
The specific application procedure of the mounting positioning marks 50, 50 is not limited, and may be formed by printing on the upright sheet 40 in advance or after the diaper main body X1 is manufactured. It may be formed in any of the manufacturing processes of the diaper main body X1.

On the other hand, the absorbent core 33 of the absorbent body of the present embodiment has an arcuate center in the front-rear direction on both sides along the leg-circumference edge EL of the exterior sheet 11, and the fit to the legs is enhanced. Yes.
As the liquid-permeable surface sheet 31 covering the surface side (skin contact surface side) of the absorbent core 33, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. The material fibers that make up the nonwoven fabric can be synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters, and polyamides, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as 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 surface sheet 31, urine and the like are quickly absorbed, and the dry touch property is excellent.
As the liquid-impervious back sheet 32 that covers the back side (non-skin contact surface side) of the absorbent core 33, a liquid-impervious plastic sheet such as polyethylene or polypropylene is used. Those having wettability are preferably used. This water-impervious / breathable sheet is a microporous sheet obtained by, for example, melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. If the sheet thickness is the same, the rigidity is lower than that of the non-porous sheet, which is superior in terms of flexibility.

The absorbent core 33 is formed by interspersing an absorbent polymer in fibers such as piled pulp or nonwoven fabric and encased with a liquid-permeable sheet such as crepe paper, nonwoven fabric sheet or perforated sheet.
Examples of the superabsorbent polymer include carboxymethyl cellulose, polyacrylic acid and salts thereof, acrylate polymer cross-linked product, starch-acrylic acid graft copolymer, starch-acrylonitrile graft copolymer hydrolyzate, polyoxyethylene cross-linked product Products, crosslinked products of carboxymethyl cellulose, polyethylene oxide, polyacrylamide and other partially crosslinked polymers, or a copolymer of isobutylene and maleic acid are preferably used. What added the blocking inhibitor in order to suppress the blocking property by moisture absorption of a product can also be used. In addition, the superabsorbent polymer has various forms such as powder, particles, granules, pellets, sol, suspension, gel, film, and nonwoven fabric. Any of them can be used in the present invention, and a particulate material is particularly preferably used.

<Auxiliary absorbent article Y1>
The absorbent pad Y1 as an auxiliary absorbent article has a liquid-permeable top sheet 61, a liquid-impervious back sheet 62, and an absorbent core 70 interposed therebetween.
