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.

Claims

1. A diaper fastening system for releasably securing first and second longitudinal ends of a diaper together, said fastening system including tab and landing members respectively mounted to said first and second longitudinal ends of said diaper, said tab member having a mounting portion, a connecting portion and a securement portion, said tab member being foldable to a Z-shape in a storage position and being deployable to a securement position to provide combined mechanical and adhesive securement with said landing member, said tab member including a facestock member having opposed inner and outer facestock surfaces, an adhesive layer having opposed inner and outer adhesive surfaces, said adhesive layer extending continuously along said facestock member adjacent said mounting, connecting and securement portions of said tab member and having said inner adhesive surface adjacent said inner facestock surface, a first release coating extending continuously along said outer adhesive surface adjacent said connecting portion, a second release coating extending continuously along the entire width and length of said outer facestock surface adjacent said mounting, connecting and securement portions of said tab member, mechanical fastening elements projecting from said outer adhesive surface adjacent said securement portion, said mounting portion being folded toward said connecting portion with said outer adhesive surface adjacent said mounting portion being secured to said first longitudinal diaper end and said securement portion being folded toward said first release coating and said connecting portion when said tab member is folded in said storage position, said securement portion being unfolded away from said first release coating to expose said outer adhesive surface and mechanical fastening elements adjacent said securement portion upon deployment of said tab member to said securement position, and said landing member including contact surface means for adhesive engagement by said outer adhesive surface adjacent said securement portion to provide immediate tack strength and mechanical engaging means for mechanical locking engagement by said mechanical fastening elements to provide shear strength, whereby said tab member and said landing member in said securement position provide combined adhesive and mechanical securement between said tab member and said landing member.

2. A diaper fastening system as in claim 1, wherein said mechanical fastening elements comprise hooks.

3. A diaper fastening system as in claim 1, wherein said mechanical fastening elements comprise separate hook elements embedded in said adhesive layer adjacent said securement portion.

4. A diaper fastening system as in claim 1, said tab member is extensible.

5. A diaper fastening system as in claim 1, wherein said mechanical fastening elements comprise hooks, said landing member comprises loops or fibrous material providing said mechanical engaging means and contact surface means.
