Abstract

A canister includes a closure configured to mount on a container to close an open mouth into a product storage region formed in the container. The closure includes a lid and a lid retainer coupled to the lid. The lid retainer is configured to mate with an external thread on the container to retain the closure in a mounted position on the container.

First claim

The invention claimed is:

1. A canister comprising
a container formed to include a product receiving chamber and a mouth arranged to open into the product receiving chamber,
a closure coupled to the container in an installed position closing the mouth, and
an annular seal unit coupled to the top wall and formed to include an annular receiving channel defined by an annular plug arranged to extend into the mouth and establish a first seal interface, an upper valve arranged to receive a filler neck of the container, and an outer valve,
wherein the closure includes a lid having a top wall and a sidewall coupled to the top wall and arranged to extend downwardly away from the top wall toward the container, the lid and the sidewall cooperating to define an interior region formed in the lid, and a series of gussets coupled to the top wall and the side wall and located in the interior region, the series of gussets reinforcing the top wall to minimize a thickness of the top wall and so that the closure withstands pressure formed in the product receiving chamber when a pressurized fluid is stored in the product receiving chamber and the closure is in the installed position, and
wherein the outer valve is configured to provide means for releasing excess pressure formed in the product storage region when the closure is being uninstalled from the filler neck.

2. The canister of claim 1 , wherein the top wall has a thickness of less than 0.06 inches.

3. The canister of claim 2 , wherein the top wall has a thickness of less than 0.04 inches.

4. The canister of claim 3 , wherein the top wall has a thickness of less than 0.03 inches.

5. The canister of claim 4 , wherein the top wall has a thickness of 0.03 inches.

6. The canister of claim 1 , wherein each gusset included in the series of gussets is spaced-apart circumferentially from each neighboring gusset by eight degrees.

7. The canister of claim 1 , further comprising a series of knurls coupled to the sidewall, the series of knurls being configured to provide a means for reinforcing the side wall to minimize a thickness of the side wall so that the closure withstands pressure formed in the product receiving chamber when the closure is in the installed position.

8. The canister of claim 7 , wherein the series of knurls is coupled to the sidewall around an annular band.

9. The canister of claim 8 , wherein the annular band has a thickness of less than 0.04 inches.

10. The canister of claim 9 , wherein the annular band has a thickness of less than 0.03 inches.

11. The canister of claim 10 , wherein the annular band has a thickness of 0.022 inches.

12. The canister of claim 7 , wherein each knurl includes a body, a first shoulder, and a second shoulder, the body of each knurl arranged to extend away from the lid and positioned between the first shoulder and the second shoulder.

13. The canister of claim 1 , wherein each gusset includes a straight portion extending between the top wall and the side wall at an angle relative to a central axis of the canister and a curved portion coupled to the top wall and the side wall to couple each gusset to the closure.

14. The canister of claim 1 , wherein each gusset has a thickness and is spaced apart from neighboring gussets by a distance and the thickness of each gusset is smaller than the distance.

15. The canister of claim 1 , wherein each gusset is spaced apart from the outer valve when the closure is in the installed position on the container.

16. A canister comprising
a container formed to include a product receiving chamber and a mouth arranged to open into the product receiving chamber,
a closure coupled to the container in an installed position closing the mouth,
wherein the closure includes a lid having a top wall and a sidewall coupled to the top wall and arranged to extend downwardly away from the top wall toward the container, the lid and the sidewall cooperating to define an interior region formed in the lid, and a series of gussets coupled to the top wall and the side wall and located in the interior region, the series of gussets reinforcing the top wall to minimize a thickness of the top wall and so that the closure withstands pressure formed in the product receiving chamber when a pressurized fluid is stored in the product receiving chamber and the closure is in the installed position, and
wherein the lid further includes a lid retainer coupled to the sidewall and formed to include internal threads, a series of speed bumps, and valve passageways, wherein the valve passageways are formed to include gaps in the internal threads to provide means for releasing excess pressure from the product receiving chamber.

17. The canister of claim 16 , wherein the lid includes a first, second, third, and fourth speed bump coupled to the side wall and positioned along the internal threads to provide means for controlling the force required to uninstall the closure from the container.

18. The canister of claim 17 , wherein the speed bumps have a thickness of less than or equal to 0.01 inches.

19. A closure comprising
a lid having a top wall and a sidewall coupled to the top wall and arranged to extend downwardly away from the top wall toward the container, the lid and the sidewall cooperating to define an interior region formed in the lid,
a series of gussets coupled to the top wall and the side wall and located in the interior region, the series of gussets configured to provide means for reinforcing the top wall to minimize a thickness of the top wall and so that the closure withstands pressure exerted on the top wall from inside the interior region of the lid, and
an annular seal unit coupled to the top wall and formed to include an annular receiving channel defined by an annular plug arranged to extend into a mouth of a container and establish a first seal interface, an upper valve arranged to receive a filler neck of the container, and an outer valve configured to provide means for releasing excess pressure formed in the container when the closure is being uninstalled from the filler neck.
