Abstract

A fastening member that is capable of attachment to a molded article is disclosed. The fastening member may include at least one fastener element extending from a base and an anchor layer attached to the base. The anchor layer may be coated with a magnetically attractable coating. The magnetically attractable coating may be substantially continuous on select portions of the anchor layer and discontinuous on other select portions of the anchor layer.

Claims

1. A fastening member suitable for attachment to a molded article, comprising:

a base having a first surface and a second surface;

at least one fastener element extending from the first surface of the base;

an anchor layer attached to the second surface, wherein at least a portion of the anchor layer extends laterally from the base; and

a magnetically attractable coating disposed on the portion of the anchor layer that extends laterally from the base.

2. The fastening member according to claim 1, wherein the magnetically attractable coating is discontinuous.

3. The fastening member according to claim 2, wherein the anchor layer has a first side and a second side, opposite of the first side, and wherein the base is attached to the first side and the discontinuous magnetically attractable coating is disposed on the first side.

4. The fastening member according to claim 1, wherein the anchor layer has a first side and a second side, opposite of the first side, and wherein the base is attached to the first side and a substantially continuous magnetically attractable coating is disposed on the second side opposite of where the base is attached to the first side.

5. The fastening member according to claim 4, wherein the magnetically attractable coating disposed on the at least a portion of the anchor layer that extends laterally from the base is discontinuous.

6. The fastening member according to claim 1, wherein the first surface of the base is connected to the second surface of the base by at least one side surface, wherein at least a portion of the at least one side surface slants away from the second surface of the base at an angle less than normal relative to the second surface.

7. The fastening member according to claim 1, wherein the anchor layer bonds to molding material during the molding process such that the fastening member is secured to the molded article.

8. The fastening member according to claim 1, wherein the anchor layer comprises a non-woven fabric.

9. The fastening member according to claim 1, wherein the anchor layer is attached to the second surface of the base by ultrasonic welding or an adhesive.

10. The fastening member of claim 1, wherein the at least one fastener element is integrally formed with the base.

11. The fastening member of claim 1, wherein the at least one fastener element comprises umbrella-shaped elements.

12. The fastening member of claim 1, wherein the base comprises an extruded thermoplastic polymer.

13. The fastening member of claim 1, wherein the magnetically attractable coating comprises iron oxide.

14. The fastening member of claim 1, wherein the base further comprises a first end and a second end, and wherein foam seals are disposed adjacent the first end and second end.

15. The fastening member of claim 1, wherein the base further comprises a first end and a second end, and wherein the anchor layer extends beyond the first end and the second end, and wherein a discontinuous magnetically attractable coating is disposed on the anchor layer that extends beyond the first end and second end.

16. A fastening member suitable for attachment to a molded article by molding the fastening member into the molded article as the article is molded, the fastening member comprising:

a base having a first surface and a second surface;

a plurality of fastener elements extending from the first surface;

an anchor layer attached to the second surface;

a magnetic seal extending outward from the base, the magnetic seal capable of magnetically coupling to a surface in a mold to prevent mold material from contacting the plurality of fastener elements during molding.

17. The fastening member of claim 16, wherein the magnetic seal comprises a portion of the anchor layer coated with a magnetically attractable coating.

18. The fastening member of claim 17, wherein the magnetically attractable coating is discontinuous.

19. The fastening member according to claim 16, wherein the first surface of the base is connected to the second surface of the base by at least one side surface, and wherein at least a portion of the at least one side surface slants away from the second surface of the base at an angle less than normal relative to the second surface.

20. A touch fastener strip, comprising

an elongated base having a first face, a second face that opposes the first face, and at least one side surface that connects the first face to the second face, wherein at least a portion of the side surface slants away from the second face at an angle less than normal relative to the second face;

a plurality of fastening elements extending from the first face of the base;

a cloth member attached to the second face of the base, the cloth member having a first portion that extends over the length of the second face of the base and a second portion that extends laterally from the base; and

a magnetically attractable coating disposed on the cloth member, wherein the coating is substantially continuous on the first portion of the cloth member and is discontinuous on the second portion of the cloth member.
