Abstract

Described is a fastening tape that includes a plurality of attachment portions extending upwardly from a bottom portion of the fastening tape. The fastening tape also includes at least one inner wall disposed adjacent to at least some of the plurality of attachment portions and at least one outer wall offset from the at least one inner wall such that a cavity is disposed between the at least one inner wall and the at least one outer wall. Finally, the fastening tape includes an injected foam member disposed in the cavity.

First claim

That which is claimed is:

1. A fastening tape comprising:
a plurality of attachment portions extending upwardly from a bottom portion of the fastening tape;
at least one inner wall disposed adjacent to at least some of the plurality of attachment portions;
at least one outer wall offset from the at least one inner wall such that a cavity is disposed between the at least one inner wall and the at least one outer wall; and
an injected foam member disposed in the cavity, wherein:
at least one of the at least one inner wall and the at least one outer wall extends along a length and a height of the cavity such that the at least one of the at least one inner wall and the at least one outer wall blocks more than approximately 50% of a side of the cavity; and
the injected foam member comprises a gasket member for sealing against a mold surface to prevent component foam from reaching the plurality of attachment portions.

2. The fastening tape of claim 1 , further comprising at least one magnetic portion.

3. The fastening tape of claim 2 , wherein the at least one magnetic portion comprises an iron monofilament that is approximately cylindrical and that extends in a longitudinal direction of the fastening tape.

4. The fastening tape of claim 2 , wherein:
the at least one magnetic portion comprises a plurality of main portions and a plurality of notches; and
the at least one magnetic portion is disposed within the cavity.

5. The fastening tape of claim 2 , wherein:
the at least one magnetic portion comprises a plurality of hook portions; and
the at least one magnetic portion is disposed within the cavity such that the injected foam member surrounds the plurality of hook portions.

6. The fastening tape of claim 1 , wherein the injected foam member comprises iron powder mixed therein.

7. The fastening tape of claim 1 , wherein the injected foam member comprises a pressure-sensitive adhesive resin.

8. The fastening tape of claim 1 , wherein at least one of the at least one inner wall and the at least one outer wall each comprises an inwardly facing protrusion configured to hold the injected foam member in position within the cavity.

9. The fastening tape of claim 1 , wherein:
a base of the cavity comprises a plurality of projections; and
the injected foam member surrounds the plurality of projections.

10. The fastening tape of claim 1 , wherein at least one of the at least one inner wall and the at least one outer wall is continuous.

11. The fastening tape of claim 1 , wherein the fastening tape comprises a mixture of plastic resin and iron powder such that at least a portion of the fastening tape is magnetic.

12. The fastening tape of claim 1 , wherein a height of the injected foam member from the bottom portion of the fastening tape is greater than a height of the at least one inner wall and a height of the at least one outer wall from the bottom portion of the fastening tape.

13. A fastening tape comprising:
a plurality of attachment portions extending upwardly from a bottom portion of the fastening tape;
at least one inner wall disposed adjacent to at least some of the plurality of attachment portions;
at least one outer wall offset from the at least one inner wall such that a cavity is disposed between the at least one inner wall and the at least one outer wall;
an injected foam member disposed in the cavity; and
at least one magnetic portion, wherein:
at least one of the at least one inner wall and the at least one outer wall extends along a length and a height of the cavity such that the at least one of the at least one inner wall and the at least one outer wall blocks more than approximately 50% of a side of the cavity; and
the at least one magnetic portion comprises an iron monofilament that is approximately cylindrical and that extends in a longitudinal direction of the fastening tape.

14. A fastening tape comprising:
a plurality of attachment portions extending upwardly from a bottom portion of the fastening tape;
at least one inner wall disposed adjacent to at least some of the plurality of attachment portions;
at least one outer wall offset from the at least one inner wall such that a cavity is disposed between the at least one inner wall and the at least one outer wall; and
an injected foam member disposed in the cavity, wherein:
at least one of the at least one inner wall and the at least one outer wall extends along a length and a height of the cavity such that the at least one of the at least one inner wall and the at least one outer wall blocks more than approximately 50% of a side of the cavity; and
at least one of the at least one inner wall and the at least one outer wall each comprises an inwardly facing protrusion configured to hold the injected foam member in position within the cavity.
