Description

Absorbent article and mounting structure of absorbent article

The present invention relates to an absorbent article that is used auxiliary with basic absorbent articles such as a pad type, a tape type, and a pants type, and a mounting structure thereof.

In addition to basic absorbent articles (also called outer) such as pad type, tape type, and pants type, excrement absorbent articles (diapers) for adults are expected to be used in combination with these. Auxiliary absorbent articles called types (also called inners) are provided, and combinations of these are widely used, particularly in care settings such as care facilities.

In particular, when the wearer is a male, the urination position changes depending on the position of the penis, so there is a problem that leakage from around the leg is likely to occur, and in order to solve this problem at the nursing care site, a flat type auxiliary absorbent By using an article and making both sides in the width direction bellows and placing the penis between the bellows-like parts, it is possible to fill the gap generated in the root groove of both legs from the groin to the crotch, especially wearing When a person is a male, a countermeasure is taken such as conically rolling it around a penis (hereinafter also referred to as male winding) (see, for example, Patent Documents 1 and 2).

Also, a bag-like absorbent article having a penis insertion opening has been proposed in order to simplify the man wearing operation and reduce leakage (see, for example, Patent Documents 3 and 4).

Japanese Patent Laid-Open No. 2006-212453 JP 2001-129002 A JP 2001-204755 A Japanese Patent No. 4388213

However, the above-described male-wrapped or bag-like absorbent article has a problem that the penis is restrained by the absorbent article in a worn state, so that the sense of discomfort is strong, and it does not make sense if the penis moves out of the article. .

In addition, the above-described bellows-like mounting form is less uncomfortable when worn compared to a male wound or bag-like absorbent article, but can completely fill a gap generated in the root groove of both legs from the groin to the crotch. This is difficult, and not only does it easily leave a gap, but also cannot easily follow the movement of the leg and the looseness tends to collapse, so there is room for improvement from the viewpoint of preventing leakage around the leg.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
(First form)
As shown in FIGS. 4 and 5, the absorbent article 10 of the first form includes a base portion 11 located in the middle in the width direction, and both side portions 12 located on both sides in the width direction of the base portion 11. Is a roll-shaped portion 13 that is thicker than the base 11 and is formed by winding the side end portion 12E so that the surface is on the inside.

As long as the absorbent article 10 is configured so that at least the roll-shaped portion 13 can absorb urine from its externally exposed surface, the internal structure is not particularly limited, and is absorbent as long as it has excellent shape maintainability. Although it can be constituted by a material alone, as shown in FIGS. 1 to 3, as shown in FIG. 1 to FIG. 3, an integral absorbent body 3 covering the base 11 and both side parts 12, and a liquid-permeable topsheet 2 covering the surface of the absorbent body 3 A structure including the liquid-permeable back sheet 1 that covers the back surface of the absorbent body 3 is simple and preferable. In this case, as shown in FIG. 4, the surface of the base 11 is formed by the top sheet 2, and the absorption to the absorbent body 3 is made through the top sheet 2, whereas the roll-shaped portion 13 is exposed outside A surface is formed by the back sheet 1, and absorption by the absorber 3 is performed through the back sheet 1. In addition, the dot pattern part in a figure has shown the adhesion part by a hot-melt-adhesive.

As the top sheet 2 and the back sheet 1, a perforated or non-porous nonwoven fabric or a perforated plastic sheet is used. When using a nonwoven fabric, the fiber is not particularly limited. In addition to synthetic fibers such as polyethylene or polypropylene such as olefins, polyesters, and amides, recycled fibers such as rayon and cupra, and natural fibers such as cotton can be used. The manufacturing method is not particularly limited, and a nonwoven fabric obtained by an appropriate processing method such as a spunlace method, a spunbond method, a thermal bond method, a melt blown method, a needle punch method, or the like 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 plastic sheet in which a large number of through holes are formed in the top sheet 2 and the back sheet 1 is used, urine and the like are quickly absorbed, and the dry touch property is excellent.

In the illustrated example, the top sheet 2 and the back sheet 1 are joined to a portion protruding from the periphery of the absorbent body 3, so that the flap portion 4 not having the absorbent body 3 is formed, but either one of the sheets is absorbed. It can also be set as the structure which does not have the flap part 4 in a part or all of circumference | surroundings by extending so that the peripheral part of the body 3 may be wound.

As the absorbent body 3, it is possible to use a laminate of pulp fibers, an aggregate of filaments such as cellulose acetate, or a nonwoven fabric, and a mixture obtained by mixing and fixing a superabsorbent polymer as necessary. . The absorbent body 3 can be packaged with a packaging sheet (not shown) having liquid permeability and liquid retention, such as crepe paper, if necessary, for holding the shape and polymer. The shape of the absorber 3 can be an appropriate shape in addition to a rectangular shape as illustrated. The fiber weight and the weight of the absorbent polymer in the absorbent body 3 can be determined as appropriate, but the fiber weight is preferably about 250 to 500 g / m ^2, and the weight of the absorbent polymer is about 50 to 250 g / m ^2. Is preferable.

Unlike the illustrated example, a known liquid-impervious sheet is disposed only on the back side of the base 11, only a part of the externally exposed surface of the roll-shaped portion 13 is liquid-permeable, or the absorber 3 in the base 11 is omitted. It is possible to make appropriate changes such as providing the absorber 3 individually for the base 11 and the side portions 12.

The size and shape of the absorbent article 10 can be determined as appropriate, but in the normal case, the width W in the unfolded state is preferably about 350 to 450 mm, and the longitudinal length L in the unfolded state is about 140 to 210 mm. It is preferable to use a horizontally long shape having a width W longer than the length L in the front-rear direction. The width (deployed state) of the base 11 is narrower than the wearer's crotch width and can be about 60 to 90 mm. The width (deployed state) of the side portions 12 is determined according to the winding length of the roll-shaped portion 13 (the length in the width direction of the wound portion), and the number of windings is about 1.5 (see FIG. 4). In this case, it is preferable to set the thickness to about 145 to 180 mm.

The absorbent article 10 configured as described above is disposed between the inner surface of the basic absorbent article 20 and the male genitalia P, as shown in FIGS. 6 to 8, and from the groin to the crotch of the wearer. The roll-shaped portions 13 of the both side portions 12 are inserted into the root grooves of both legs T, and the male genital P is disposed between the roll-shaped portions 13 so that the male genital P is covered with the base 11 and attached. Can do. In this mounted state, the gap generated in the root groove of both legs T from the groin to the crotch can be filled with the roll-shaped portion 13 capable of absorbing urine, and the urine heading around the leg T can be filled with the roll-shaped portion 13. It can be absorbed effectively. Moreover, since the roll-shaped portion 13 is rich in elasticity and shape maintainability (hardness of shape collapse), it fits firmly in the groove at the base of the leg T and deforms and restores following the body movement of the leg T and the like. In addition, it is difficult for deformation to occur. Therefore, leakage from around the leg T hardly occurs. Moreover, the male genitalia P is not strongly restrained, and it is hard to produce a sense of incongruity. In addition, the code | symbol D in FIG. 8 has shown the wearer's lower abdominal part D. FIG.

In particular, as illustrated, when the winding of the roll-shaped portion 13 is not fixed, the user can return or advance the winding of the roll-shaped portion 13 as necessary, so that the position of the roll-shaped portion 13 It is possible to adjust the diameter, elasticity and ease of deformation of the roll-shaped portion 13 by adjusting the diameter, loosening or tightening the winding, and obtaining an appropriate wearing state even if there are some individual differences be able to. Further, when the winding of the roll-shaped portion 13 is not fixed, the roll-shaped portion 13 swells and fits so as to fill a gap generated in the root groove of the leg T by the action of loosening the winding. The property of deforming and restoring following the body movement of the leg T and the like is also extremely high. The basic absorbent article 20 is generally provided with a three-dimensional gather 24. In such a case, if the absorbent article 10 is arranged between the three-dimensional gather 24, the roll-shaped portion 13 is loosened even if the winding is loose. Since it is restrained by the gathers 24, the winding of the roll-shaped part 13 becomes difficult to collapse.

In addition, as shown in the figure, the base 11 and the both sides 12 have an integral absorbent body 3 and a liquid permeable sheet covering both the front and back surfaces of the absorbent body 3. The entire portion 12 can absorb urine from both the front and back surfaces, and the absorbed urine can diffuse throughout the absorber 3. Further, due to the rigidity of the absorbent body 3, the roll-shaped portions 13 of the both side portions 12 are urged toward the root grooves of both legs T in the mounted state. The twelve roll-shaped portions 13 can swing around the boundary with the base portion 11, and the dynamic fit is excellent, and the pressure on the male genital P from the side is reduced.

On the other hand, the base 11 can be unfixed to the basic absorbent article 20, but, as shown in the figure, on the back surface of the base 11, a male material (hook tape) of an adhesive layer or a hook-and-loop fastener (mechanical fastener). It is also a preferred form to provide a misalignment stopping portion 5 made up of or the like to prevent misalignment of the base portion 11. In addition, the illustration form assumes the case where the slip prevention part 5 is formed with the adhesive layer, and the code | symbol 6 is a peeling sheet which covers an adhesive layer. In use, the release sheet 6 is peeled off to expose the pressure-sensitive adhesive layer and adhere to the inner surface of the basic absorbent article 20.

(Second form)
In the said 1st form, since the roll-shaped part 13 of the both-sides part 12 is separated, it is not only bulky in the product packaging state or the time of carrying and storage before use, but it is easy to lose its shape. Therefore, as shown in FIG. 9, the roll-shaped portions 13 of the both side portions 12 are in contact with or close to each other on the side surfaces of the base portions 11, and at least one roll-shaped portion 13 is unwound during use. A form is also proposed in which a space 13D is provided between the roll-shaped portions 13 of the side portions 12. In such a form, it is very compact during product packaging and when being carried and stored before use, and in accordance with the wearer's body dimensions, the position and diameter of the roll-shaped portion 13 and the roll-shaped portion 13 The mutual distance 13D can be adjusted.

In the second embodiment, it is preferable to fix the roll-shaped portion 13 so as to be able to be released in order to maintain the shape. For example, as shown in FIG. 12 (a), the fixing may be performed such that the opposite side surfaces of the roll-shaped portion 13 are detachably joined by a joining means 15 such as a pressure-sensitive adhesive layer or a male material of a hook-and-loop fastener, or FIG. As shown in FIG. 12, the adhesive tape 16 is applied so as to straddle between the upper surfaces of both roll-shaped portions 13, and the adhesive tape 16 is peeled off and removed to remove the fixing, or as shown in FIG. Thus, both the roll-shaped parts 13 are passed through an annular body 17 (for example, a rubber band or a cylindrical shape) made of a flexible material such as paper, nonwoven fabric, or plastic film, and the annular body 17 is removed. Thus, the fixing can be released.

(Third form)
In the said 1st form, since the roll-shaped part 13 of the both-sides part 12 is separated, it is not only bulky in the product packaging state or the time of carrying and storage before use, but it is easy to lose its shape. In the second embodiment, there is room for improvement in compactness. Therefore, as shown in FIG. 10, the roll-shaped absorbent article 10 is wound around the side end 12 </ b> E on the other side so that the surface is on the inside, starting from the side end 12 </ b> E on one side. Is also proposed (third embodiment). In use, as shown in FIG. 11, the other side portion 12 is unwound from the roll shape and rewound, or the whole is expanded and then rewound, and the roll-shaped portions of both side portions 12 as shown in FIG. 13 is formed and then mounted. In such a form, it is very compact when the product is packaged and when it is carried and stored before use, and the shape is not easily collapsed. In use, the position and diameter of the roll-shaped portion 13 and the mutual distance 13D of the roll-shaped portion 13 can be adjusted according to the body dimensions of the wearer.

Also in the third embodiment, it is preferable to fix the roll shape so that it can be released in order to maintain the shape. For example, as shown in FIG. 12 (d), the fixing is performed by joining a roll-shaped absorbent article 10 winding end portion 10 </ b> E and a portion facing the inside thereof with an adhesive layer or a male member of a hook-and-loop fastener. As shown in FIG. 12 (e), the winding end portion 10E of the absorbent article 10 in a roll shape is fixed with an adhesive tape 16, and the adhesive tape 16 is peeled off and removed. As shown in FIG. 12 (f), the absorbent article 10 in a roll shape is made of an annular body 17 (for example, rubber band) made of a flexible material such as paper, nonwoven fabric, or plastic film. (It may be cylindrical.) It is possible to adopt a configuration in which the fixing is released by removing the annular body 17 by passing through the inside.

(4th form)
As shown in FIG.13 and FIG.14, it is also a preferable form that the absorbent article 10 is individually packaged (packed individually) by a bag body 18. FIG. 13 shows a packaging example of the absorbent article 10 of the second form, and FIG. 14 shows a packaging example of the absorbent article 10 of the third form. In particular, as in the case of the bag 18 shown in the figure, when the individual packaging is carried out in close contact with both sides of the absorbent article 10 in the width direction, the shape of the absorbent article 10 can be maintained, and the above-described winding fixation Can be omitted, and the winding can be unfixed (in other words, the bag 18 serves as a fixing means capable of releasing the winding). Of course, the individual packaging is preferable in terms of hygiene.

The bag body 18 is preferably formed by forming a flexible sheet such as paper, non-woven fabric, or plastic film into a cylindrical shape and sealing the openings at both ends with a heat seal such as a heat seal. A form widely used in packaging, a form widely used in hand towels, and the like can be adopted.

<Others>
In order to obtain the mounting structure of the present invention, it is easier to mount a roll-shaped portion as shown in FIG. 4 because the number of operations is smaller and the shape is wrinkled. However, a user can wear a flat product (having the same appearance as the state shown in FIGS. 1 and 2) after the user winds both sides to form a roll-like portion.

The absorbent article according to the present invention can be used supplementarily regardless of the form of the basic absorbent article, such as a pad type, a tape type, and a pants type. Hereinafter, the form of a basic absorbent article will be described with reference to an example of a pad type absorbent article.

15 to 18 show an example 20 of a pad type absorbent article. The pad-type absorbent article 20 has a crotch portion C2 and an abdominal side portion F2 and a back side portion B2 extending on both front and rear sides thereof, and an inner surface of a liquid-impermeable back sheet 21 and a transparent portion. It has a basic structure in which an absorber 23 is interposed between the liquid top sheet 22.

The dimensions of each part of the pad-type absorbent article 20 can be appropriately determined. For example, the total length (length in the front-rear direction) L1 is about 350 to 700 mm, and the total width W1 is about 130 to 400 mm (however, the width of the absorbent surface of the diaper) In this case, the length of the crotch portion C2 in the front-rear direction is about 10 to 150 mm, the length of the ventral portion F2 is about 50 to 350 mm, and the length of the back portion B2 in the front-rear direction The thickness can be about 50 to 350 mm.

As the absorbent body 23, it is possible to use a laminate of pulp fibers, an aggregate of filaments such as cellulose acetate, or a nonwoven fabric, and a mixture obtained by mixing and fixing a superabsorbent polymer as necessary. . If necessary, the absorber 23 can be wrapped with crepe paper (not shown). In addition, the shape of the absorbent body 23 can be determined as appropriate, and in the illustrated example, in order to improve the fit to the inside of the thigh, the front-rear direction intermediate region including the crotch portion C2 has a constricted shape along the leg circumference. A rectangular shape or the like can also be used.

The fiber basis weight and the basis weight of the absorbent polymer in the absorbent body 23 can be appropriately determined. The fiber basis weight is preferably about 100 to 600 g / m ^2, and the basis weight of the absorbent polymer is about 0 to 400 g / m ^2. It is preferable to do this.

The back sheet 21 is provided on the back side of the absorber 23 so as to protrude a predetermined length from the periphery of the absorber 3. As the back sheet 21, a sheet having moisture permeability can be used in addition to a polyethylene film or the like without impairing water shielding from the viewpoint of preventing stuffiness. 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. Can be used. Even in such a moisture-permeable sheet, the transmission of odor is suppressed. In order to make the back surface of the pad-type absorbent article feel like a cloth, an exterior sheet 21C such as a nonwoven fabric is laminated on the outer surface of the backsheet 21, or a laminated sheet having a nonwoven fabric laminated on the outer surface is used as the backsheet 21. be able to. As raw materials for these non-woven fabrics, synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and amide, recycled fibers such as rayon and cupra, and natural fibers such as cotton can be used.

The surface side of the absorber 23 is covered with a liquid-permeable top sheet 22. Although the absorber 23 partially protrudes from the side edge of the top sheet 22 in the illustrated form, the width of the top sheet 22 can be widened so that the side edge of the absorber 23 does not protrude. As the top sheet 22, a perforated or non-porous nonwoven fabric or a perforated plastic sheet is used. As the material fiber constituting the nonwoven fabric, synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and amide, recycled fibers such as rayon and cupra, and natural fibers such as cotton can be used.

At both ends in the front-rear direction of the pad-type absorbent article 20, the liquid-permeable top sheets 22 are attached to the front and rear ends of the absorbent body 23 so as to extend to the front and rear sides, and end flap portions EF where the absorbent body 23 is not present are formed. Is formed.

At both side portions of the pad type absorbent article 20, the back sheet 21 extends outward from the side edge of the absorbent body 23, and the surface of the portion from the extending portion to the side portion of the top sheet 22. Thus, the outer side portion 24x of the gather sheet 24s forming the three-dimensional gather 24 is pasted over the entire front-rear direction, thereby forming the side flap portion SF in which the absorber 23 does not exist. These bonded portions are indicated by dot patterns in FIGS. 17 and 18, and can be formed by hot melt adhesive, heat sealing, or ultrasonic sealing.

The absorbent body intervening portion other than the end flap portion EF and the side flap portion SF constitutes a main body portion BD that is a main absorption region of excrement. Although the dimensions of the end flap part EF and the side flap part SF can be determined as appropriate, the back sheet 21, the liquid-permeable top sheet 22, and the gather sheet 24 s are securely bonded together at the end flap part EF and the side flap part SF. Therefore, it is preferable that at least a part protrudes 10 mm or more from the boundary with the main body.

In the illustrated embodiment, the side edge of the side flap portion SF is bound so that the middle in the front-rear direction follows the leg periphery in accordance with the side edge of the absorber, but may be a rectangular shape without the neck. Also, when providing such a constricted portion along the leg circumference, the position of the constricted portion is biased to one side from the center in the front-rear direction, the front-rear length in the one-side portion is shortened, and the front-rear length in the other-side portion is increased. It is common to make the length longer and the one side part forward and the other side part rear (forward mounting). This is because, assuming a normal wearing state covering a wide area up to the buttocks and a female wearer, it is desirable that the longer front-rear length of both sides in the front-rear direction of the constricted part is the rear in the wearing state. The ventral portion F2 and the back portion B2 in the form correspond to this. However, the direction of wearing can be changed freely by the user.For example, when increasing the urination absorbency in men, the longer front-rear length of the front and rear sides of the constricted part is the front in the wearing state. That is, mounting (reverse mounting) is also performed so that the back portion B2 is positioned on the ventral side.

As a material for the gather sheet 24s, a plastic sheet or a melt-blown nonwoven fabric can be used. However, in terms of touch to the skin, a nonwoven fabric that is water-repellent treated with a water repellent such as silicone is preferably used. The

A portion 24c on the center side in the width direction of the gather sheet 24s extends to the top sheet 22, and an elongated elastic member 24g is stretched along the front-rear direction at the end portion on the center side in the width direction. It is fixed with a melt adhesive or the like. As the elongated elastic member 24g, styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone, polyester, etc., which are formed in a thread shape, a string shape, a belt shape, or the like. Ordinarily used materials can be used.

Further, the gather

sheets

24s and 24 are fixed to each other in the width direction outside portion 24x by being bonded and fixed to the inner surface of the article (the top sheet 22 surface and the back sheet 21 surface in the illustrated embodiment) across the entire front and rear direction. Portion 24c is bonded and fixed to the inner surface of the article (the surface of the top sheet 22 in the illustrated embodiment) at both ends in the front-rear direction, and between the both ends in the front-rear direction, the inner surface of the article (the surface of the top sheet 22 in the illustrated embodiment). It is not fixed. As shown in FIG. 18, this non-fixed portion is a portion that becomes a barrier portion that can stand up with respect to the inner surface of the article (the surface of the top sheet 22 in the illustrated embodiment), and the upright base end 24b has a width in the gather sheet 24s. It is located at the boundary between the outer fixed portion 24x and the inner portion 24c.

The present invention is suitable for auxiliary absorbent articles used in combination with basic absorbent articles such as pad type, tape type, pants type, etc., but by using a liquid-impermeable sheet as a back sheet, It can also be used as an absorbent article.
