Abstract

The present invention concerns an auxiliary pad for absorbent article that can prevent body fluid from leaking along with the dislocation of an absorbent article such as sanitary napkin, and provides a hygienic article that can reduce the occurrence of body fluid leak, even when the dislocation of fitting happens, all the way securing a sufficient adhesion to the inside of the thigh.

An auxiliary pad for absorbent article (2), comprising an absorbent sheet body (5) adhered to the inside of the thigh of the wearer for absorbing body fluid, a linkage stem body (9) for linking the absorbent sheet body and an junction sheet body (7), and the junction sheet body (7) to which an adhesive (6) is applied, is attached to a sanitary napkin (10) to constitute a sanitary article (1).

Claims

1. An auxiliary pad for attaching to an absorbent article, comprising:

an absorbent sheet body including an absorbent body for absorbing liquid and a single cover sheet for covering the absorbent body,

a junction sheet body having an adhesive layer for attaching to the absorbent article, and

a linkage stem body for linking said absorbent sheet body and the junction sheet body,

wherein said absorbent sheet body has a plurality of layers, and at least one of said layers has an elastic recovery sheet,

wherein the single cover sheet surrounds the plurality of layers and the elastic recovery sheet, and

wherein said linkage stem body has such flexibility that it can prevent said absorbent sheet body and said absorbent article from moving together.

2. The auxiliary pad for attaching to an absorbent article according to claim 1, wherein said linkage stem body is attached so as to be positioned substantially in the middle of said auxiliary pad for attaching to an absorbent article.

3. The auxiliary pad for attaching to an absorbent article according to claim 1 or 2, wherein a. height dimension of said linkage stem body ranges from 1 to 15 mm.

4. The auxiliary pad for attaching to an absorbent article according to claim 1 or 2, wherein said linkage stem body includes an elastic flexible member.

5. The auxiliary pad for attaching to an absorbent article according to claim 1 or 2, wherein said linkage stem body has a linkage sheet.

6. The auxiliary pad for attaching to an absorbent article according to claim 1 or 2, wherein the absorbent sheet body has a convex portion having a gable-roof shape formed by bending.

7. The auxiliary pad for attaching to an absorbent article according to claim 6, further comprising a restriction sheet for restricting development of a bent portion attached to both base portions in the longitudinal direction of said convex portion.

8. The auxiliary pad for attaching to an absorbent article according to claim 1 or 2, wherein the auxiliary pad for attaching to an absorbent article is an auxiliary pad for incontinence of urine.

9. The auxiliary pad for attaching to an absorbent article according to any claim 1 or 2, wherein the auxiliary pad for attaching to an absorbent article is an auxiliary pad for absorbing a vaginal discharge.

10. A linkage stem body for connecting a general absorbent article, which can be provided for a general use for absorbing body fluid, to a special absorbent article, which has body fluid absorption capacity less than said general absorbent article, and which can be provided for use with the general absorbent article to function to supplement its body fluid absorption capacity,

wherein the linkage stem body comprising:

a single cover sheet surrounding an absorbent body of the special absorbent article, the single cover sheet having a left end portion having a back face and a right end portion having a back face, the left and right end portions back faces being joined onto a back face side of the absorbent body; and

an extending portion formed on a lower side of the linkage stem body.

11. A hygienic article, comprising:

a general absorbent article, provided for absorbing body fluids,

a special absorbent article, which has body fluid absorption capacity less than said general absorbent article, and which can be provided for use with the general absorbent article to supplement the body fluid absorption capacity, and

a linkage stem body for connecting said general absorbent article to said special absorbent article,

wherein said special absorbent article comprises;

a plurality of layers, and at least one of said layers has an elastic recovery sheet for preventing deformation; and

a single cover sheet surrounding the plurality of layers and the elastic recovery sheet, and

wherein said general absorbent article and said special absorbent article are used respectively solely or in combination, and used appropriately in combination with said linkage stem body.
