Abstract

The invention described herein pertains generally to an applicator for use in translating a grip-enhancing substance onto a piece of equipment. The applicator is essentially tubular in nature and has a longitudinal slit along the length of the applicator thereby permitting a piece of equipment to be inserted thereto. The applicator has an absorbent inner component which is adhesively secured to the foamed exterior component, the inner layer having the grip-enhancing substance applied thereto. Through the application of a force, typically a squeezing action, onto the exterior of the applicator, a controllable amount of the grip-enhancing substance is transtarred from the inner component to the inserted piece of equipment. In one embodiment, the grip-enhancing substance is a replacement for pine tar, and is a synthetic polymer blend, the degree of tack of the product being both a function of the composition of the polymer(s) used in the composition, and when the composition is a mixture of two or more polymers, by the ratio of the two components.

Claims

1. An applicator for grip-enhancing substances which comprises:

(a) a foamed pliable polymer tubular member, the member having

(i) an essentially non-absorbent outer portion, and

(ii) an absorbent inner portion; and

(b) a synthetic polymeric-containing grip-enhancing substance in associative contact with the inner portion, wherein the grip-enhancing substance is a polymer blend of a polymer and a wax which is a solid at room temperature, and further wherein the degree of tack which is transferrable onto an apparatus is controlled by the relative ratios between the polymer and the wax.

2. The applicator of claim 1 wherein the synthetic polymer-containing substance has a tack value of from 0.2 to 1.0.

3. The applicator of claim 2 wherein the polymer has a molecular weight from 50 to 100,000.

4. The applicator of claim 3 wherein the polymer has a molecular weight from 2,000 to 80,000.

5. The applicator of claim 4 wherein the polymer has a molecular weight from 20,000 to 60,000.

6. The applicator of claim 3 wherein the tubular member has a longitudinal slit disposed therein.

7. An applicator for grip-enhancing substances which comprises:

(a) an essentially foamed pliable polymer tubular outer member;

(b) an absorbent inner member in adhesive contact with the outer member and essentially contiguous therewith; and

(c) a grip-enhancing substance in associative contact with the inner member, wherein the grip-enhancing substance is a polymer blend of a polymer and a wax which is a solid at room temperature, and further wherein the degree of tack which is transferrable onto an apparatus is controlled by the relative ratios between the polymer and the wax.

8. The applicator of claim 7 wherein the grip-enhancing substance is selected from the group consisting of pine tar and polymers having a tack value of from 0.2 to 1.0.

9. The applicator of claim 8 wherein the polymer has a molecular weight from 50 to 100,000.

10. The applicator of claim 9 wherein the polymer has a molecular weight from 2,000 to 80,000.

11. The applicator of claim 10 wherein the polymer has a molecular weight from 20,000 to 60,000.

12. The applicator of claim 7 wherein the inner member is a laminate having at least two layers.

13. The applicator of claim 12 wherein the laminate further comprises a barrier layer.

14. An applicator for grip-enhancing substances which comprises:

(a) an essentially foamed pliable polymer tubular outer member having a longitudinal slit disposed therein;

(b) an absorbent inner member in adhesive contact with the outer member and essentially contiguous therewith; and

(c) a synthetic polymeric-containing grip-enhancing substance in associative contact with the inner member, wherein the grip-enhancing substance is a polymer blend of a polymer and a wax which is a solid at room temperature, and further wherein the degree of tack which is transferrable onto an apparatus is controlled by the relative ratios between the polymer and the wax.

15. The applicator of claim 14 wherein the synthetic polymer-containing substance has a tack value of from 0.2 to 1.0.

16. The applicator of claim 15 wherein the polymer has a molecular weight from 50 to 100,000.

17. The applicator of claim 16 wherein the polymer has a molecular weight from 2,000 to 80,000.

18. The applicator of claim 17 wherein the polymer has a molecular weight from 20.000 to 60,000.

19. The applicator of claim 14 wherein the absorbent inner member is a laminate having at least two layers.

20. The applicator of claim 19 wherein the laminate further comprises a barrier layer.
