Abstract

A grip and grip plug, the grip having a grip cavity extending from an open grip cavity bottom end; a tab aperture and a lock protrusion aperture formed proximate the grip cavity bottom end; the grip plug having a skirt extending from at least a portion of the plug body; a tether portion and a lock protrusion extending from the skirt, wherein the tether portion is positionable through at least a portion of the lock protrusion aperture, and wherein the lock protrusion extends beyond at least a portion of the lock protrusion aperture; and a tab extending from the skirt, proximate a first end portion of the grip plug body, wherein the tab is removably engageable with at least a portion of the tab aperture, such that the grip plug is positionable within at least a portion of the open grip cavity bottom end.

Claims (42)

1. A grip, comprising:

a grip body having a grip cavity extending from an open grip cavity bottom end, wherein a lock protrusion aperture is formed proximate said open grip cavity bottom end;

a grip plug body extending from a first end portion to a second end portion;

a skirt extending downward from at least a portion of said grip plug body;

a pull tab extending from a portion of said plug body;

a tether portion extending from said skirt, proximate said second end portion of said grip plug body, wherein a lock protrusion extends from said tether portion, wherein said tether portion is positionable through at least a portion of said lock protrusion aperture; and

a tab extending from said skirt, proximate said first end portion of said grip plug body.

2. The grip plug of claim 1 , wherein said grip plug body is a substantially oval shape.

3. The grip plug of claim 1 , wherein two or more flex recesses are formed through at least a portion of said skirt, wherein each flex recess is formed proximate said tab.

4. The grip plug of claim 1 , wherein said lock protrusion is a T-shaped lock protrusion.

5. The grip plug of claim 1 , wherein said grip plug is formed of a substantially resilient material.

6. The grip plug of claim 1 , wherein each of said grip plug body, said skirt, said tab, said tether portion, said lock protrusion, and said pull tab are integrally formed as a single component.

7. A grip and grip plug, said grip comprising:

a grip body having a grip cavity extending from an open grip cavity bottom end to a grip cavity top wall portion;

a tab aperture formed proximate said grip cavity bottom end;

a lock protrusion aperture formed proximate said grip cavity bottom end;

said grip plug, comprising:

a grip plug body extending from a first end portion to a second end portion;

a skirt extending from at least a portion of said grip plug body;

a pull tab extending from a portion of said plug body;

a tether portion extending from said skirt, proximate said second end portion of said grip plug body, wherein a lock protrusion extends from said tether portion, wherein said tether portion is positionable through at least a portion of said lock protrusion aperture, and wherein said lock protrusion extends beyond at least a portion of said lock protrusion aperture; and

a tab extending from said skirt, proximate said first end portion of said grip plug body, wherein said tab is removably engageable with at least a portion of said tab aperture, such that when said tab is engaged within at least a portion of said tab aperture, said grip plug is positioned within at least a portion of said open grip cavity bottom end.

8. The grip plug of claim 7 , wherein said grip plug body is a substantially oval shape.

9. The grip plug of claim 7 , wherein two or more flex recesses are formed through at least a portion of said skirt, wherein each flex recess is formed proximate said tab.

10. The grip plug of claim 7 , wherein said lock protrusion is a T-shaped lock protrusion.

11. The grip plug of claim 7 , wherein said grip plug is formed of a substantially resilient material.

12. The grip plug of claim 7 , wherein each of said grip plug body, said skirt, said tab, said tether portion, said lock protrusion, and said pull tab are integrally formed as a single component.

13. The grip plug of claim 7 , wherein when said grip plug is positioned within at least a portion of said open grip cavity bottom end, frictional engagement between at least a portion of said grip plug and interior side walls forming said grip cavity hermetically seal said grip cavity.

14. A grip having a grip plug, comprising:

a grip body having a grip cavity that extends from an open grip cavity bottom end to a grip cavity top wall portion;

a tab aperture formed proximate said grip cavity bottom end;

a lock protrusion aperture formed proximate said grip cavity bottom end;

said grip plug having a grip plug body;

a skirt that extends from at least a portion of said grip plug body;

a tether portion that extends from said skirt, wherein a lock protrusion extends from said tether portion, wherein said tether portion is positionable through at least a portion of said lock protrusion aperture, and wherein said lock protrusion extends beyond at least a portion of said lock protrusion aperture; and

a tab that extends from said skirt, wherein said tab is removably engageable with at least a portion of said tab aperture, such that when said tab is engaged within at least a portion of said tab aperture, said grip plug is positioned within at least a portion of said open grip cavity bottom end.

15. The grip plug of claim 14 , wherein said grip plug body is a substantially oval shape.

16. The grip plug of claim 14 , wherein two or more flex recesses are formed through at least a portion of said skirt, wherein each flex recess is formed proximate said tab.

17. The grip plug of claim 14 , wherein said lock protrusion is a T-shaped lock protrusion.

18. The grip plug of claim 14 , wherein said grip plug is formed of a substantially resilient material.

19. The grip plug of claim 14 , wherein a pull tab extends from a portion of said plug body.

20. The grip plug of claim 14 , wherein when said grip plug is positioned within at least a portion of said open grip cavity bottom end, frictional engagement between at least a portion of said grip plug and interior side walls forming said grip cavity hermetically seal said grip cavity.
