Abstract: A transdermal patch is provided for use during oil delivery to a user's skin. The patch has a first foam member and a second foam member positioned adjacent the first foam member. An adhesive member is attached to the second foam member for securing the patch to a user's skin. A release liner covers and extends across the adhesive member. A gap can be formed between the first foam member and the second foam member and surrounds the first foam member. The first foam member has a thickness which is greater than a thickness of the second foam member.

Abstract: Fastening systems for releasably securing two components together include tab and landing members. In a first arrangement, a Z-fold tab member has combined mechanical and adhesive engagement. A second arrangement includes adjacent adhesive and cohesive contact portions. A third arrangement contoured apertures and mechanical engaging elements. A fourth arrangement includes apertures and mechanical engaging elements sized and arranged so that each aperture receives a plurality of mechanical engaging elements. A fifth arrangement includes tab and landing members that cooperate to provide a color indicia of secure adhesive engagement.

Abstract: A fastening system for releasably securing a diaper provides both mechanical and adhesive or cohesive securement. Tab members comprise a facestock layer, a contact layer of adhesive or cohesive overlying at least a portion of the facestock layer, and mechanical fastening elements projecting from at least a portion of the contact layer. The facestock layer includes extensible and substantially nonextensible polymeric portions. A landing member includes complementary mechanical fastening elements and a contact surface or cohesive for engagement with the tab adhesive or cohesive. A method is also disclosed for making the fastening system.

Abstract: A release liner providing a release surface which comprises a first olefin polymer film formed having dispersed therein by high shear mixing a release substance which is polyethyleneimine octadecyl carbamide, polyvinyl octadecyl carbamate or a mixture thereof, coextruded or cocast onto a film formed from a second olefin polymer. The release liner has particular utility in diaper tape application.

Abstract: A refastenable diaper is provided with a securing zone on the diaper outer cover of a peak strength of less than 2750 grams/inch. A refastenable adhesive taping system for the diaper includes an adhesive fastening tape comprising a flexible backing and a layer of pressure-sensitive adhesive permanently combined to said flexible backing and adapted to be applied to and released from the securing zone to fasten and open the diaper. The adhesive exhibits a 180.degree. peel adhesion of the tape to the securing zone that is less than the peak strength of the securing zone. The adhesive is selected to be within a specified rheological window, that is, have a maximum tan delta, or (tan delta).sub.max, of from 1.5 to 2.5 at 20.degree. C., reached at a frequency, or (w).sub.max, of greater than 500 rad/sec.

Abstract: Thermoplastic elastomers provide autoadhesive properties at room temperature having improved anti-blocking properties. The elastomers are substantially non-adhesive. The elastomers include physical cross-links which enable the elastomers to be formed as laminates with other polymeric materials by processing techniques involving application of heat.

Abstract: A bandage for the transdermal or topical administration of a drug over an extended period of time comprising an impermeable backing sheet, a solid drug pellet on the backing sheet, and a layer of contact adhesive covering the pellet and backing sheet. In another form, the adhesive is carried by a web made of a non-woven or woven fabric. Control over the rate of dissolution of the solid drug can be achieved by varying the type of web fabric, the type of adhesive, and the thickness of the adhesive.
