摘要:
An absorbent article includes an absorbent pad and an outer cover. The absorbent pad includes an absorbent core enveloped by a first layer and a second barrier layer. The first layer and the second barrier layer are secured to each other outwardly of a perimeter of the absorbent core. A deformable third layer is disposed in the absorbent article between the first layer and an outer cover. The deformable layer is adhesively secured to the inner surface of the outer cover. There is no significant securement between the deformable layer and the first layer. In embodiments where the outer cover is extensible in a cross-direction and/or a longitudinal direction, the deformable layer deforms during extension of the outer cover, but such deforming has no significant harmful effect on the first layer. Therefore, damage to the first layer, the second barrier layer, or the absorbent pad, and concomitant release of superabsorbent material from the absorbent pad, is avoided.

A disposable absorbent article includes a multi-functional fastening system which includes a pair of primary fasteners which are located on the opposed side edges in one of the waist regions of the absorbent article. The primary fasteners are configured to releasably engage the opposite waist region of the absorbent article. The fastening system also includes at least one secondary fastener which is located in one of the waist regions of the absorbent article. The secondary fastener is configured to releasably engage the opposite waist region of the absorbent article to conform the waist regions of the article to a wearer's body after the primary fasteners have been releasably engaged. The primary fasteners may be prefastened to allow the disposable absorbent article to be pulled on or off over the wearer's hips. The fastening system may further include a belt segment to which the secondary fasteners are attached.

The present invention is generally directed to adhesive compositions comprising selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic. or isotactic configuration) is used to prepare adhesives of the present invention. As an example, a selected amount of isotactic polypropylene is blended with a selected amount of atactic polypropylene to prepare an adhesive composition having one or more performance properties (e.g., bond strength) that are superior to the performance properties of a conventional hot-melt adhesive.

An absorbent article includes at least one fit panel which is located in one of the waist sections of the absorbent article adjacent an end edge of the absorbent article. The fit panel extends laterally beyond both of the side edges of an absorbent chassis of the absorbent article. The fit panel may include a center bridge panel and a pair of laterally opposed side panels which are connected to opposed lateral edges of the bridge panel. Desirably, the bridge panel and side panels provide individual zones of elasticity across the width of the fit panel which have different elastic properties.

Disposable absorbent articles which include an outer cover, an absorbent chassis, an adjustable belt and belt loops are described. The adjustable belt is located in one waist region of the absorbent article and includes a fastener on each of it's opposed end portions. The belt loops are located inward from and adjacent to each of the fasteners on the adjustable belt and the longitudinal ends of the belt loops are attached to the absorbent article to slidably contain the adjustable belt between the belt loops and the waist region. The fasteners on the adjustable belt are configured to releasably engage the opposite waist region of the absorbent article. Desirably, the adjustable belt and belt loops are located on an inner surface of the absorbent article such as the bodyfacing surface of the outer cover or the bodyside liner. The absorbent article may also include fasteners on the belt loops to provide another pair of fasteners.

An absorbent article includes an absorbent pad and an outer cover. A release agent is applied to one of the outer surface of the absorbent pad and the inner surface of the outer cover. The release agent prevents at least a portion of the outer cover from adhering to the absorbent pad. In embodiments where the outer cover is extensible in a cross-direction and/or a longitudinal direction, the release agent prevents the absorbent pad from resisting mobility of the outer cover. Thus the absorbent pad has substantially no adhesion to the outer cover where the release agent is applied. Therefore, tearing of the absorbent pad and damage to, or release, of superabsorbent material from the absorbent pad during extension of the outer cover, is prevented. The release agent can be a silicon-active agent or a powder material having properties that prevent adhesion between adhesive and a forming tissue of the absorbent pad, or the outer cover.

This invention pertains to cutting dies for cutting continuous strip elements from a continuous web of fibrous and/or polymeric material. An improved cutting die has an elevated stripping land between adjacent but spaced elongated cutting knives. The elevated stripping land obviates the trim element becoming lodged in the trim zone between the cutting knives, and thereby assists in stripping the trim element from the trim zone.
