Article closure tape for an absorbent

Abstract

The present invention refers to a closure tape (10) for an absorbent article, particularly for a disposable diaper (1), for fastening of the article on the body of a person, the closure tape being attachable to the outside surface (3) of the diaper (1) through one of its end portions (17) and comprising a backing (11) bearing a continuous or discontinuous adhesive layer (12), a fastening means (15) and a stretchable elastic sheet (13), the backing (11) being essentially non-elastic and / or essentially non-extensible, the support sheet comprising the backing (11) and the continuous or discontinuous adhesive layer exhibiting one or more incisions (14) in the area of the elastic sheet with at least one of the incisions extending in machine direction over the full width of the backing (11) and the end portion (17) being separated from the incision (14) closest to the end portion (17), by a sufficiently large distance (22) to prevent the incisions (14) essentially from opening when attaching the end portion (17) to the outside surface (3) of the diaper (1) and bending the remaining part of the closure tape (10) to contact the inside surface (2) of the diaper (1).

Description

FIELD OF THE INVENTION[0001] The invention relates to a closure tape for an absorbent article, particularly for a disposable diaper, for fastening of the article on the body of a person, said closure tape being attachable to the absorbent article through one of its end portions and comprising a backing, a fastening means and an elastic sheet to render the closure tape elastically stretchable. The invention furthermore relates to a prelaminated closure tape in a stable roll from which the closure tape can be cut.BACKGROUND OF THE INVENTION[0002] Absorbent articles such as disposable diapers are provided with closure tapes which are anchored to the absorbent article through one of its end portions by means of, for example, a pressure-sensitive adhesive layer. The opposite end portion of the closure tape comprises a fastening means to close the absorbent article around the wearer's body and fasten the absorbent article on the body. Among these closure tapes, there have also been descri...

Problems solved by technology

While these closure tapes are useful and of commercial importance they are sometimes disadvantageous in that the method of preparing them is relatively complicated and requires secure bonding of the tape segments.

Using closure tapes with elastically stretchable backings is sometimes disadvantageous because the closure tape which is attached to the diaper may exhibit an insufficient rigidity orthogonal to the long axis of the backing (machine direction) and be floppy.

This peel mode type of attachment offers a relatively low bonding strength and may fail when securing the diaper around the wearer's body or during use.

The slits are furthermore easily contaminated.
