Abstract

Absorbent article such as a diaper and an incontinence guard provided with a pair of belt members (9) attached to the rear portion (6) of the article and which are intended to be fastened together around the waist of the wearer and where said front portion (5) is provided with fastening means (8) intended to be fastened to the belt members (9), in such a way that the article will assume a pantlike shape, where the belt members (9) form a part of the waist portions of the pant. The belt members (9) are before use double-folded and cut in an arcuate shape in which the tangent (12) to the arcuate curve (13) formed by the respective longitudinal edges (9a,b) of the belt members (9) in the area of the fold (14) makes a substantially right angle to the fold. The belt members are in their double folded condition applied to the rear portion (6) of the article, and when the article is to be used they are intended to be unfolded, at which the belt members in their unfolded position form an arcuate shape where the portions on either sides of the fold (14) are the mirror image of each other.

Claims

1. Absorbent article such as a diaper and an incontinence guard comprising a liquid permeable topsheet (2), a liquid impermeable backsheet (3) and an absorbent body (4) enclosed therebetween, said article having a front portion (5), a rear portion (6) and a crotch portion (7) therebetween, and further is provided with a pair of belt members (9) attached to the rear portion (6), alternatively to the front portion, of the article and which are intended to be fastened together around the waist of the wearer and where said front portion (5), alternatively said rear portion, is provided with fastening means (8) intended to be fastened to the belt members (9), in such a way that the article will assume a pantlike shape, where the belt members (9) form a part of the waist portions of the pant, characterized in that the belt members (9) before use are double-folded and cut in an arcuate shape in which the tangent (12) to the arcuate curve (13) formed by the respective longitudinal edges (9a,b) of the belt members (9) in the area of the fold (14) makes a substantially right angle to the fold, that the belt members in their double folded condition are applied to the rear portion (6) of the article, and that they when the article is to be used are intended to be unfolded, at which the belt members in their unfolded position form an arcuate shape where the portions on either sides of the fold (14) are the mirror image of each other.

2. Absorbent article as claimed in claim 1, characterized in that the belt members (9) are kept in place in their double folded position against the rear portion (6) of the article by means of an easily breakable seal (15).
