Abstract

The invention described herein is a shaped seal or gasket for use with a screw cap as commonly used in chemical barrels. The shaped gasket has a profile that includes a winged portion for contacting a sealing surface. The winged portion of the gasket defines a concave surface. The gasket has a second surface, or zone of contact, for contacting against a second surface, such as the underside of a screw cap. The winged portion of the gasket profile is wider than the zone of contact. The gasket profile can take on many different configurations, as shown in the drawings.

Claims

1. A gasket for use with a cap for creating a seal with a sealing surface opposing the cap, said gasket having a zone of contact for contacting the underside of the cap, the gasket profile including winged portions extending away from the zone of contact, said winged portions forming a width greater than the width of the zone of contact, the winged portions forming a concave surface for creating a seal against the sealing surface.

2. The gasket of claim 1, the winged portions terminating in ends and forming the concave surface there between, the concave surface having two flat surfaces meeting at an vertex.

3. The gasket of claim 2, where at least one of the ends is rounded.

4. The gasket of claim 2, where at least one of the ends is pointed.

5. The gasket of claim 2, the gasket having a concave surface extending form the zone of contact to an end of a winged portion.

6. The gasket of claim 1, wherein the winged portions form a width greater than the width of the zone of contact only when compressed between the cap and the sealing surface.

21. The gasket of claim 1, wherein the sealing surface includes a shape to be received by the concave surface of the gasket.

7. A gasket having a first surface for contacting the surface of another object and a concave surface for contacting a sealing surface opposing the second surface, the concave surface being wider than the first surface.

8. The gasket of claim 7, wherein the first surface is flat.

9. The gasket of claim 7, wherein the first surface is shaped to complement the second surface.

10. The gasket of claim 7, wherein the gasket includes a second concave surface, the second surface being between the first surface and the first concave surface.

11. The gasket of claim 7, wherein the concave surface is formed by two straight surfaces meeting at a junction.

12. The gasket of claim 7 wherein the sealing surface includes a protrusion to be received by the concave surface of the gasket when the first surface and sealing surface act to compress the gasket there between.

13. The gasket of claim 12, wherein the protrusion is shaped to complement the shape of the first concave surface.

14. The gasket of claim 7, wherein the gasket is annular.

15. A gasket for creating a seal between two surfaces, the gasket having a shaped profile including:

a zone of contact for contacting a first surface,

a concave surface for contacting a second surface, said concave surface being of greater width than the zone of contact.

16. The gasket of claim 15, wherein the gasket is annular.

17. The gasket of claim 15, wherein the concave surface has a depth of between ⅛

^th and ⅞

^th s of the total height of the gasket profile.

18. The gasket of claim 15, wherein the gasket is made of a material from the following group:

rubber, nylon, silicone, urethane, or neoprene, polypropylene, or polyethylene.

19. The gasket of claim 15, the concave surface having a width greater than the zone of contact only when the gasket is compressed between the two surfaces.

20. The gasket of claim 15, further including at least one additional concave surface located between the first concave surface and the zone of contact.
