Closure tape with patterned adhesive
View Patent ↗Various fastening tape closure assemblies are described. The closure tapes are useful in the manufacture of disposable articles, and particularly disposable diapers. The closure tapes generally include a fastening tape and a release tape that at least partially covers the fastening tape during storage and transport of the tape and/or the disposable article. The release tapes include a layer of adhesive for bonding to a region of a diaper. The adhesive layer is in a patterned configuration.
1. A composite tape from which a closure tab for disposable articles can be cut, the tape comprising:
a fastening tape defining a distal end and an opposite proximal end, the fastening tape including a backing film, and an adhesive layer disposed on at least a portion of the backing film;
a release tape defining a distal end and an opposite proximal end, the release tape including a backing film, an adhesive layer disposed on a first face of the backing film, a hinge component disposed at the proximal end of the release tape, the release tape also defining a second face oppositely directed from the first face;
wherein the fastening tape and the release tape are sized and configured for attachment to one another such that the hinge component of the release layer contacts the adhesive layer of the fastening tape and is adhesively attached thereto, and the adhesive layer of the release tape is arranged in a pattern configuration
wherein the pattern configuration includes a plurality of rows of adhesive, each adhesive row separated from immediately adjacent adhesive rows by a spacing row.
2. The composite tape of claim 1 wherein the length of the release tape is less than the length of the fastening tape.
3. The composite tape of claim 1 further comprising:
an outwardly projecting finger lift disposed at a distal end of the fastening tape.
4. The composite tape of claim 3 wherein the finger lift is colored.
5. The composite tape of claim 1 wherein the distal end of the fastening tape has a serrated configuration.
6. The composite tape of claim 1 wherein the release tape is positioned relative to the fastening tape such that the distal end of the fastening tape extends beyond the distal end of the release tape.
7. The composite tape of claim 1 wherein the ratio of widths of the adhesive row to the spacing row is from about 0.5 to about 2.5:1.
8. The composite tape of claim 7 wherein the ratio is about 1.5:1.
9. The composite tape of claim 1 wherein the adhesive layer of the fastening tape is a continuous layer.
10. The composite tape of claim 1 wherein the composite tape is in roll form.
11. The composite tape of claim 1 wherein the fastening tape defines an adhesive-free region along a face of the backing film of the fastening tape directed toward the release tape and extending from the hinge component toward the proximal end.
12. The composite tape of claim 1 wherein the release tape defines an adhesive-free region along a face of the backing film of the release tape directed toward the fastening tape and extending from the hinge component toward the proximal end.
