Claim 1
Independent Claim
251 words
A disposable diaper, comprising: an absorbent pad assembly having a pair of side edges, a pair of end edges connecting the side edges, a front surface, a backing sheet of fluid impervious material defining a back surface of the pad assembly, an absorbent pad, and a laterally extending end section adjacent one end edge of the pad assembly; and a tape fastener comprising, a release sheet having a release back surface and being attached to the back surface of said end section adjacent a side edge of the pad assembly, a securement section having adhesive on a front surface releasably attached to the back surface of the release sheet and having a release back surface, and a retaining section having adhesive on a front surface releasably attached to the back surface of the securement section, said retaining section being peeled from the securement section and folded around the side edge of the pad assembly into a configuration with the retaining section overlying the front surface of the pad assembly and with the adhesive on the retaining section facing away from the front surface of the pad assembly, said end section of the pad assembly being folded over an adjacent portion of the pad assembly into a configuration with the adhesive on the retaining section contacting a portion of the pad assembly underlying the end section and retaining the end section in the overlying configuration, and said securement section being peeled from the release sheet to secure the diaper about an infant.
Claim 2
Dependent Claim
251 words
A disposable diaper, comprising: an absorbent pad assembly having a pair of side edges, a pair of end edges connecting the side edges, a front surface, a backing sheet of fluid impervious material defining a back surface of the pad assembly, an absorbent pad, and a laterally extending end section adjacent one end edge of the pad assembly; and a tape fastener comprising, a release sheet having a release back surface and being attached to the back surface of said end section adjacent a side edge of the pad assembly, a securement section having adhesive on a front surface releasably attached to the back surface of the release sheet and having a release back surface, and a retaining section having adhesive on a front surface releasably attached to the back surface of the securement section, said retaining section being peeled from the securement section and folded around the side edge of the pad assembly into a configuration with the retaining section overlying the front surface of the pad assembly and with the adhesive on the retaining section facing away from the front surface of the pad assembly, said end section of the pad assembly being folded over an adjacent portion of the pad assembly into a configuration with the adhesive on the retaining section contacting a portion of the pad assembly underlying the end section and retaining the end section in the overlying configuration, and said securement section being peeled from the release sheet to secure the diaper about an infant.
