  The female urination auxiliary pad of the present invention is used by being attached to an absorbent article, and is used by being attached at a position facing a urination part of a female wearer. The female urination auxiliary pad of the present invention can be attached to, for example, a disposable diaper, a urine pad, an incontinence pad, a sanitary napkin, and the like, and is suitably used for a disposable diaper and a urine pad that handle a large amount of urine. The female urination auxiliary pad of the present invention can be attached to the absorbent article so that it can be freely adjusted to a position facing the urination part of the wearer according to the body shape of the female wearer. If the urination assist pad is used, any wearer can improve the fit around the urination part and easily prevent side leakage of urine.

  The female urination auxiliary pad of the present invention has an annular elastic body and also has fixing means for attaching the female urination auxiliary pad to the absorbent article. The female urination auxiliary pad of the present invention is used by being attached to the top sheet of the absorbent article so that the female urination portion is located in the opening of the annular elastic body. Since the auxiliary pad attached to the absorbent article acts as a urine weir, it is difficult for urine to spread on the top sheet. As a result, urine is easily absorbed in the region within the opening formed by the annular elastic body, and side leakage is less likely to occur.

  The elastic body is preferably a member that can be elastically deformed under the handling conditions of general absorbent articles. Moreover, it is preferable that an elastic body is a member which can track with respect to the twist or bending of an absorbent article, when attached to an absorbent article. Examples of the elastic body include foamed polymers such as foamed urethane, foamed rubber, and foamed polyester; natural rubber; synthetic rubbers such as urethane rubber, styrene butadiene rubber, butadiene rubber, and ethylene propylene rubber; cotton, sponge, pulp fiber, and synthetic fiber. A fiber lump that is an aggregate of fibers such as can be used. The fiber lump may contain a water absorbent resin. As the elastic body, it is preferable to use a foamed polymer or a fiber lump as one having excellent cushioning properties.

  The shape of the elastic body is not particularly limited as long as it is annular. Specific examples include a circle, an ellipse, a rectangle, a gourd shape, a rectangle with rounded corners, and the like. Preferably, the elastic body has a shape that is long in one direction. That is, the elastic body preferably has a lateral direction and a longitudinal direction longer than the lateral direction. In this case, the elastic body is attached to the absorbent article such that the longitudinal direction coincides with the front-rear direction (longitudinal direction) of the absorbent article. In addition, the front-back direction of an absorbent article means the direction from the stomach side to the back side when wearing an absorbent article. Moreover, the direction which is on the same plane as the absorbent article and is orthogonal to the front-rear direction is defined as the lateral direction of the absorbent article.

  FIG. 1 shows an example of an annular elastic body. FIG. 1A shows an example of a substantially elliptical elastic body, and FIG. 1B shows an example of a gourd-shaped elastic body. A preferable size and the like of the annular elastic body will be described with reference to FIG.

  The ring of the annular elastic body has a certain range of width (thickness) 11. Accordingly, the annular elastic body has an inner edge and an outer edge. The width 11 of the ring is preferably in the range of 5 mm to 50 mm (more preferably in the range of 10 mm to 30 mm). If the width 11 of the ring is 5 mm or more, when the female urination auxiliary pad is attached to the absorbent article, the auxiliary pad easily forms a weir. If the width 11 of the ring is 50 mm or less, flexibility is ensured at a location where the auxiliary pad is attached to the absorbent article to the extent that no practical problem is caused.

  The inner side of the inner edge of the annular elastic body, that is, the opening of the annular elastic body has a shape larger than an ellipse having a minor axis of 20 mm and a major axis of 50 mm (more preferably an ellipse having a minor axis of 50 mm and a major axis of 100 mm). Is preferred. If the opening of the ring-shaped elastic body has a size including at least the ellipse, it becomes easy to place the female urination portion in the opening and easily collect urine without overflowing from the weir formed by the auxiliary pad. Become.

  The outer edge of the annular elastic body preferably has a lateral length 12 of 300 mm or less, and more preferably 250 mm or less. If the length 12 in the lateral direction of the outer edge of the annular elastic body is 300 mm or less, the lateral length of the outer edge of the elastic body tends to be less than the lateral length of the absorbent article, and the elastic body becomes an absorbent article. Easy to install on the top sheet.

  The outer edge of the annular elastic body preferably has a longitudinal length 13 of 350 mm or less, and more preferably 300 mm or less. If the length 13 in the longitudinal direction of the outer edge of the annular elastic body is 350 mm or less, the elastic body has an appropriate size to function as a weir against urine.

  The shape of the annular elastic body is preferably a substantially elliptical shape as shown as an example in FIG. The substantially elliptical shape includes a rectangle with rounded corners. If the elastic body is substantially elliptical, it becomes easy to place the female urination section in the opening. In addition, a dam is formed surrounding the urine drainage part, and urine absorption by the absorbent article is easily performed mainly in the opening, so that side leakage is less likely to occur. When the annular elastic body has a substantially elliptical shape, the opening preferably has a lateral length 14 of 50 mm or more and 250 mm or less, and a longitudinal length 15 of 100 mm or more and 300 mm or less.

  The shape of the annular elastic body is also preferably a gourd shape as shown as an example in FIG. The gourd shape is not particularly limited as long as a part of the ring-shaped longitudinal direction is narrow. If the elastic body is a gourd shape, the auxiliary pad is less likely to be distorted when the auxiliary pad is used by attaching the auxiliary pad to the absorbent article so that the constricted portion of the gourd shape is located in the crotch portion of the wearer. Therefore, the fit of the auxiliary pad to the wearer is enhanced, and urine lateral leakage is less likely to occur.

  When the annular elastic body has a gourd shape, the opening preferably has a length 15 in the vertical direction of 100 mm or more and 300 mm or less. The lateral length 16 of the opening is preferably 250 mm or less. In the case of a gourd shape, the lateral length 16 of the opening means the length of the longest portion in the lateral direction. The lateral length 17 of the gourd-shaped constricted portion is preferably 50 mm or more.

  As shown in FIG. 1B, the gourd-shaped elastic body may have substantially the same size with a constricted portion interposed therebetween. In addition, as shown in FIG. 2, a gourd shape may be used in which one is large and the other is small across the constricted portion. However, the latter is preferred as the gourd shape. In this case, it is preferable that the auxiliary pad is used by being attached to the absorbent article such that the larger part is located in the urination part with the constricted part interposed therebetween. If the elastic body has a shape as shown in FIG. 2, the auxiliary pad is excellent in fit and leakage prevention.

  It is preferable that both ends in the longitudinal direction of the annular elastic body are thicker than other portions. Since the horizontal direction center part of an elastic body exists only in the vertical direction both ends, if the vertical direction both ends of an elastic body are thicker than another part, the thickness of an elastic body will increase in the horizontal direction central part. That is, it is preferable that the annular elastic body has a thicker central portion in the horizontal direction at both ends in the vertical direction than in other portions. If both ends in the longitudinal direction of the annular elastic body are thick, when the auxiliary pad is attached to the absorbent article and used, even if the auxiliary pad is curved along the wearer's skin, A gap is less likely to occur between the center of the direction and the skin of the wearer, and adhesion with the wearer is increased. As a result, leakage from the front and rear ends of the auxiliary pad is less likely to occur. The effect is particularly effective when the auxiliary pad is curved along the wearer's skin in a transverse section.

  FIG. 3 shows a trihedral view of the substantially elliptical elastic body shown in FIG. In FIG. 3, both ends in the longitudinal direction of the elastic body are thicker than the other parts, and the central part in the horizontal direction is thicker than the other parts.

  The above description regarding the size of the elastic body means the size and shape of the elastic body in a state where the elastic body is covered with a sheet, as will be described later. For example, when the elastic body is compressed by being covered with the sheet, it means the size and shape of the elastic body in the compressed state.

  The female urination auxiliary pad of the present invention has an annular elastic body and also has fixing means for attaching the female urination auxiliary pad to the absorbent article. The female urination auxiliary pad of the present invention is used by being attached to the top sheet of the absorbent article. Therefore, the fixing means is not particularly limited as long as it can be fixed to the top sheet.

  Since the top sheet is generally composed of a liquid-permeable nonwoven fabric, a member that can be attached to the nonwoven fabric is preferably used as the fixing means. Specifically, as the fixing means, an adhesive (for example, an adhesive tape, an adhesive layer or the like), a hook member (for example, a member having a hook shape such as a bowl shape, a bowl shape, or a mushroom shape) may be employed. That's fine.

  When an adhesive is used as the fixing means, the adhesion between the auxiliary pad and the top sheet of the absorbent article is enhanced, and the auxiliary pad becomes a weir and urine is difficult to spread on the top sheet. Therefore, side leakage of urine is effectively prevented.

  When a hook member is used as the fixing means, the auxiliary pad can be attached to and detached from the absorbent article, and the attachment position of the auxiliary pad to the absorbent article can be adjusted.

  The fixing means is directly or indirectly attached to one surface of the annular elastic body. As will be described later, when the elastic body is covered with a sheet, the fixing means may be attached to the sheet. The fixing means may be provided on the entire one surface of the elastic body or may be provided partially.

  In the female urination auxiliary pad of the present invention, the elastic body is preferably covered with a liquid-impermeable or water-repellent sheet (hereinafter sometimes referred to as “coating sheet”). The auxiliary pad frequently touches the wearer's skin when used attached to the absorbent article. However, when the portion of the auxiliary pad that touches the wearer is made of a hydrophilic material or a material that can hold liquid, the wearer feels wet at the portion of the auxiliary pad that touches, and the feeling of wear tends to deteriorate. At the same time, the skin may be damaged when the skin is placed in a wet state at the portion. From such a viewpoint, the elastic body is preferably coated with a liquid-impermeable or water-repellent sheet. If the elastic body is covered with a liquid-impermeable or water-repellent sheet, the wearing feeling of the auxiliary pad is improved and the wearer is less likely to be damaged by the skin.

  As the liquid-impermeable or water-repellent sheet, a nonwoven fabric, a plastic film, a laminate of a plastic film and a nonwoven fabric, or the like may be used. As the liquid-impermeable or water-repellent nonwoven fabric, a nonwoven fabric formed from hydrophobic fibers such as polypropylene, polyethylene, polyester, polyamide, and nylon can be used. Considering the point that the wearer feels good, it is preferable to use a liquid-impermeable or water-repellent nonwoven fabric as the covering sheet.

  The elastic body may be covered with one cover sheet, or may be covered by being sandwiched between two or more cover sheets. In any case, it is preferable that the entire surface of the elastic body is covered with a covering sheet.

  A preferable combination of the elastic body and the covering sheet is a combination using a foamed polymer or a fiber lump as the elastic body and a liquid-impermeable or water-repellent nonwoven fabric as the covering sheet. If the auxiliary pad is constituted by such a combination, an auxiliary pad that is excellent in cushioning and touch and has a high urine damming effect can be obtained.

For example, a nonwoven fabric formed from hydrophilic fibers such as cellulose and rayon; and a nonwoven fabric formed from hydrophobic fibers such as polypropylene, polyethylene, polyester, polyamide, and nylon, and the surface of the hydrophobic fibers is a surfactant. Those hydrophilized with can be used.

  The backsheet is preferably a liquid-permeable or liquid-impermeable sheet material. For example, when the absorbent article is a urine pad, the backsheet may be liquid permeable. As the liquid-permeable sheet material, a material usable for the top sheet may be used. As the liquid-impermeable sheet material, a nonwoven fabric formed from hydrophobic fibers such as polypropylene, polyethylene, polyester, polyamide, and nylon, a plastic film, and the like can be used. Moreover, you may use the laminated body of a nonwoven fabric and a plastic film.

  The absorbent core is not particularly limited as long as it is provided between the top sheet and the back sheet and can absorb excrement such as urine. As the absorbent core, for example, a molded body in which the absorbent material is molded into a predetermined shape is used, or the absorbent material is covered with a paper sheet (for example, tissue paper) or a liquid-permeable nonwoven fabric sheet. Can do. Examples of the absorbent material contained in the absorbent core include hydrophilic fibers such as pulverized pulp fibers and cellulose fibers, and water-absorbing resins such as polyacrylic acid-based, cellulose-based, and starch / acrylonitrile-based materials. The absorbent material preferably contains at least a water absorbent resin. Moreover, you may use what mixed or disperse | distributed the water absorbing resin to the aggregate | assembly of a hydrophilic fiber as an absorptive material.

  The absorbent article of the present invention has a top sheet, a back sheet, and an absorbent core provided therebetween, and the female urination auxiliary pad of the present invention is located at a position where the female urination portion of the top sheet faces. As long as it is attached to, the specific aspect of the absorbent article is not particularly limited. Examples of absorbent articles include disposable diapers, urine pads, incontinence pads, sanitary napkins and the like.

  When the absorbent article is a urine pad, an incontinence pad, or a sanitary napkin, examples of these shapes include a substantially rectangular shape, an hourglass shape, and a gourd shape.

  When the absorbent article is a disposable diaper, the disposable diaper is provided with a pair of fastening members on the left and right, and is an open-type disposable diaper that is formed into a pants shape when worn by the fastening member, or a front abdomen and a back part. It may be a pants-type disposable diaper in which a waist opening and a pair of leg openings are formed by bonding. The front part, the back part, and the crotch part are referred to as the front part of the wearer's abdomen when wearing disposable diapers and the back part of the part as it applies to the buttocks side of the wearer. A portion that is located between the abdomen and the back portion and is placed between the wearer's crotch is referred to as a crotch portion.

  When the absorbent article is a pants-type disposable diaper, the disposable diaper includes, for example, an absorbent main body having a top sheet, a back sheet, and an absorbent core at a crotch portion of an exterior member formed in a pants type. It may be. Moreover, a disposable diaper consists of a laminated body by which the absorptive core was distribute | arranged between the top sheet and the back sheet, for example, and this laminated body may be formed in the underpants type.

  In the absorbent article of the present invention, the auxiliary pad is attached to the position of the top sheet facing the female urination part, so that the fit around the urination part is improved and the auxiliary pad acts as a urine weir. Side leakage is less likely to occur.

  If the hook member is attached to the auxiliary pad as a fixing means, the absorbent pad of the present invention can be detachably handled even if the auxiliary pad is once attached to the top sheet.
