Abstract

Unique designs, devices, systems, materials and fabrication methods are provided including adhesive closure devices that are easily released and are suitable for extended/repeated use in a variety of applications.

First claim

What is claimed is:

1. A closure device capable of forming a releasable seal, comprising
an adhesive pad comprising:
a backing layer; and
an elastic planar layer having a first and a second side, the first side applied to the backing layer, and the second side having an adhering surface, wherein the backing layer has a higher in-plane stiffness than the elastic planar layer; and

an adherent member having an adhering surface;
wherein the adhesive pad and the adherent member are releasably attachable to one another when pressed against each other with the adhering surface of the second side of the layer of elastic material and the adhering surface of the adherent member positioned face-to-face.

2. The closure device of claim 1 , further comprising a tether component attached to the backing layer on a side opposite the elastic planar layer, wherein the tether is capable of bearing a load force.

3. The closure device of claim 2 , wherein the backing layer, the tether component, and the adherent member together consecutively form a single continuous component.

4. The closure device of claim 3 , wherein the adhering surface of the adhesive pad of the second side of the elastic planar layer and the adhering surface of the adherent member are on a same side of the single continuous component.

5. The closure device of claim 1 , wherein the backing layer comprises a natural fabric material, a synthetic fabric material, or a blend or hybrid thereof.

6. The closure device of claim 5 , wherein the natural fabric material is selected from cotton, hemp, wool, silk, bamboo string, cellulose, jute, and pina.

7. The closure device of claim 5 , wherein the synthetic fabric material is a fabric of polyester, polyolefin, spandex, nylon, carbon fiber, polyaramid, carbon fiber polyaramid hybrid, carbon fiber basalt hybrid, fiberglass, carbon fiber, or fiberglass hybrid.

8. The closure device of claim 5 , wherein the adhering surface of the adherent member comprises a surface of metal, wood, carbon, polymers, gels, leather, plastic or ceramic.

9. The releasable, surface-adhesive closure device of claim 1 , wherein the releasable seal is part of a closed loop when the adhesive pad and the adherent member are pressed against each other.

10. The closure device of claim 1 , wherein the adhering surface of the adhesive pad has an area in the range of 0.01 cm 2 -100 m 2 .

11. The closure device of claim 1 , wherein the adhering surface of the adhesive pad has a uniform thickness of 0.0001 mm-10 cm.

12. The closure device of claim 1 , wherein the elastic planar layer has an elastic modulus of 0.001 MPa-100,000 MPa.

13. The closure device of claim 1 , wherein said closure device is capable of multiple cycles of closure and release.

14. The closure device of claim 1 , wherein the adherent member is a second adhesive pad, and wherein the first and second adhesive pads are releasably attachable to one another using the adhering surfaces of the two adhesive pads.

15. The closure device of claim 14 , further comprising a tether attached to at least one adhesive pad.

16. The closure device of claim 1 , wherein the elastic planar layer includes an elastomeric material.

17. The closure device of claim 1 , wherein the adhesive pad and the adherent member form a seal when they are attached to one another.
