Description

  The present invention relates to a turn-up prevention attachment.

  Conventionally, when a light incontinence liner, a pad, a sanitary napkin, or the like is attached to an undergarment, an anti-slip adhesive is provided on the outer side of the backsheet, thereby fixing to the undergarment. However, when a light incontinence liner or a pad is attached to the shorts, the front and rear ends of these products may turn over or twist when the movement is intense, for a long time, or at bedtime. When turning or twisting occurs, it not only makes the skin feel uncomfortable but also causes pain and itching.

  In order to improve such a situation, there are the following prior arts to prevent turning over. An adhesive material is provided on the outer peripheral edge of the leak-proof material (Patent Document 1). This is difficult to turn over, but is difficult to peel off on the other side. A slip prevention adhesive layer is formed over the entire area of the release material (Patent Document 2). This is because the rear end is easy to turn because the rear end is concave. Although the front end reinforcing sheet and the rear end reinforcing sheet prevent the flaps from being turned over (Patent Document 3), when the unevenness is caused by the reinforcing sheet, there is a possibility of impairing the mounting feeling and fit.
