A diaper fastener which comprises tape and has first and second anchoring portions and an attachment portion. The first and second anchoring portions are secured, respectively, to the inner and outer surfaces of the diaper adjacent a lateral margin and each is in a force-transmitting relation to the attachment portion. The attachment portion has a pressure-sensitive adhesive disposed on one surface thereof, whereby it is securable to a remote region of the diaper for retaining the diaper on the wearer.

The pressure sensitive adhesive bandage disclosed includes a novel low density polyethylene closed cell foam backing sheet with a glossy, smoothly pebbled, low friction, non-adherent face surface and a coating-adherent rear surface having a pressure sensitive adhesive to which is adhered an absorbent pad. In comparison with bandages having a vinyl backing sheet, the novel plasticizer-free polyethylene foam backing sheet provides improved shelf life, while its low density and low hand provides superior smoothness, flexibility, conformability and softness.

Adhesive bandage with foam backing

A scrub sponge comprising, a packet having a rupturable wall and a closed chamber containing a liquid scrub agent, and a cover of foam material having a cavity to receive the packet. The sponge has a puncture member intermediate the cover and the rupturable wall, with the puncture member having a projection facing toward the puncturable wall such that the projection pierces the puncturable wall when the puncture member is pressed toward the packet to release the scrub agent into the cover.

A dressing composite comprising, a bandage comprising an elongated backing sheet having a back surface facing away from a patient after application of the bandage, a front surface facing toward the patient after application of the bandage, an absorbent pad located over the front surface of the backing sheet and intermediate opposed ends of the backing sheet, and an adhesive covering a substantial portion of the front surface of the backing sheet intermediate the pad and the opposed ends of the backing sheet. The dressing composite has a package comprising a front cover sheet extending the length of the bandage, and having a width greater than the width of the bandage backing sheet, with opposed side margins of the front cover sheet extending past opposed sides of the bandage, and an inner release surface releasably attached to the exposed adhesive of the bandage. The dressing composite has a back cover sheet extending the length of the bandage, and having a width greater than the width of the bandage backing sheet, with opposed side margins of the back cover sheet extending past opposed sides of the bandage, and an adhesive on a front surface of the back cover sheet with a portion of the adhesive being releasably attached to the back surface of the backing sheet, and a portion of the adhesive extending along the side margins on the front surface of the back cover sheet and being releasably attached to a release surface on the side margins of the facing inner surface of the front cover sheet. The front and back cover sheets are releasably attached together adjacent at least one end of the bandage.

Dressing composite

A bandage comprising, a pressure-sensitive tape strip having a central portion, and a pair of opposed end portions extending from the central portion for securing the bandage to a patient. The bandage has a protective member having a back surface secured to the front surface of the tape strip central portion, and a front surface defining a cavity. The bandage also has an absorbent pad received in the cavity with the protective member absorbing blows applied to the bandage to minimize trauma to a wound covered by the bandage.

Bandage with protective member

A disposable diaper comprising, an absorbent pad assembly having an absorbent pad, and a sheet covering a surface of the pad. The sheet has a slit defining a strip connected to the remaining portion of the sheet. The diaper has a pressure-sensitive tape strip secured to the pad assembly and extending across an opening defined by the slit, with the tape strip having adhesive facing toward the sheet strip. The sheet strip is releasably attached to the adhesive and is peeled from the tape strip in order to expose the adhesive through the opening for use in securing the diaper about an infant.

Disposable diaper with flap covered tape fastener

A disposable diaper comprising, an absorbent pad assembly having opposed surfaces, a pair of side edges, and a pair of end edges connecting the side edges. The diaper has a tape fastener comprising, tape means having a first portion secured to one of the surfaces of the pad assembly, a split securement portion for attachment to a spaced portion of the diaper and distribution of forces in the fastener.

Diaper with elastic fastener

A disposable diaper comprising, an absorbent pad assembly, a release sheet on a surface of the pad assembly adjacent a side edge, a rape strip having a first portion secured to the surface of the pad assembly, a securement portion releasably attached to the release sheet, and an extensible central portion connecting the first and securement portions.

Diaper with extensible fastener

A disposable diaper comprising, an absorbent pad assembly having an absorbent pad, a front surface, a back surface, a pair of side edges, and a pair of end edges connecting the side edges. The pad assembly has a plurality of longitudinally extending folds defining a box-pleat configuration of the pad assembly having a pair of first fold lines defining a longitudinally extending central panel, and a pair of second fold lines defining a pair of first pleat panels intermediate the first and second fold lines and overlying the central panel, and defining a pair of second pleat panels extending from the second fold lines. The pad assembly has a lateral fold of the box-pleat assembly along a fold line spaced slightly from one of the end edges and defining an end section of the pad assembly intermediate the lateral fold line and the one end edge, with the end section being folded over the front surface of an adjacent portion of the pad assembly. The diaper has a tape fastener comprising, a release sheet on the back surface of the end section, and a tape strip having a first inner section attached to a second pleat panel beneath the central panel of the folded over end section. The tape strip also has a second outer section extending around the back surface of the end section and having an adhesive surface releasably attached to the release sheet.

Disposable diaper with fastener retained end barrier

A disposable diaper comprising, an absorbent pad assembly, a release sheet on a surface of the pad assembly adjacent a side edge, a tape strip having a first portion secured to the surface of the pad assembly, a securement portion releasably attached to the release sheet, and an extensible central portion connecting the first and securement portions.

Disclosed is a diaper comprising an absorbent body, diaper end margins defining front and back waistline regions and lateral margins extending between the end margins. Each lateral margin has a predetermined unconstrained length between those end margins. The diaper further comprises limiting means operative to shorten the length of a lateral margin from its unconstrained length.

Diaper fastener

A disposable diaper comprising, an absorbent pad assembly having opposed surfaces, a pair of side edges, and a pair of end edges connecting the side edges. The diaper has a tape fastener comprising, tape means having a first portion secured to one of the surfaces of the pad assembly, a securement portion for attachment to a spaced portion of the diaper, an extensible portion connecting the first and securement portions, and elastic means constraining expansion of the extensible portion.

Diaper with elastic fastener tab

A disposable diaper comprising, an absorbent pad assembly having opposed surfaces and a side edge. The diaper has a tape fastener comprising, a pressure-sensitive tape strip having a first end portion secured to one of the surface of the pad assembly adjacent a side edge, a second securement end portion for securing the diaper about an infant, and an elastic band extending around and laterally constraining a central portion of the strip intermediate the first and second portions. The band reduces the lateral dimensions of the central portion and the effective normal length of the strip, such that the second strip portion is longitudinally extensible relative the first portion by increasing the size of the central portion from reduced to enlarged lateral dimensions while expansing the band responsive to forces applied in a longitudinal direction against the strip.
