Abstract
Abstract A reusable closure for containers having an opening in a surface thereof. A seal of size and shape sufficient to cover the opening in the container and having a bore therethrough is positioned such that the bore generally is aligned with a portion of the opening including opposed edges thereof. A threaded cap has a diameter less than that of the bore, whereby threaded engagement between the cap and opposed edges of the opening is achieved. Tightening the cap holds the seal firmly in place, thereby maintaining a positive closure of the opening. The seal may abut a lip of the container thereby restricting lateral movement of the cap. The seal and the threaded cap may be separate elements or of integral construction. The invention is particularly suited for use in containers having a convenience opening known as pop-top cans.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
148 words
In combination, a container having an opening in a surface thereof, which opening has a pair of opposed edges, and a closure device therefor, said closure device comprising: a cap member having an upper part and a threaded lower part, a sealing member of an overall size and shape sufficiently large to over the opening, said cap member passing through a central portion of the sealing member such that the lower threaded part thereof is located below the sealing member, the threads of the threaded cap member being of a size such that they threadedly engage the said opposed edges of the opening, said upper part of the cap member comprising means for cooperating with the sealing member to urge the same into tight sealing engagement with the top of the can to cover the opening as the said lower threaded part is threadedly tightened into the opening.
Claim 2
Dependent Claim
148 words
In combination, a container having an opening in a surface thereof, which opening has a pair of opposed edges, and a closure device therefor, said closure device comprising: a cap member having an upper part and a threaded lower part, a sealing member of an overall size and shape sufficiently large to over the opening, said cap member passing through a central portion of the sealing member such that the lower threaded part thereof is located below the sealing member, the threads of the threaded cap member being of a size such that they threadedly engage the said opposed edges of the opening, said upper part of the cap member comprising means for cooperating with the sealing member to urge the same into tight sealing engagement with the top of the can to cover the opening as the said lower threaded part is threadedly tightened into the opening.
Claim 3
Dependent Claim
85 words
The invention of claim 1, wherein said sealing member comprises: a support having a bore completely therethrough for receiving and positioning said threaded lower part and being engaged along the upper surface thereof by a lower surface of the said upper part of the member and; a resilient sealing material having a bore completely therethrough for receiving said threaded lower part, and engaged by said support member, and compressed thereby when the threads of said threaded lower part engage the opposed edges of the opening.
Claim 4
Dependent Claim
16 words
The invention of claim 2 wherein said cap member and said support are of integral construction.
Claim 5
Dependent Claim
30 words
The invention of claim 1 wherein a surface of said sealing member contacting the surface of the container is substantially the same overall shape as the shape of the opening.
Claim 6
Dependent Claim
21 words
The invention of claim 1 wherein a surface of said sealing member contacting the surface of the container is substantially circular.
Claim 7
Dependent Claim
17 words
The invention of claim 1 wherein said cap member and said sealing member are of integral construction.
Claim 8
Dependent Claim
25 words
The invention of claim 1 wherein the container further has a lip raised above the surface thereof and said sealing member means abuts the lip.
Claim 9
Dependent Claim
172 words
In combination, a container having an opening in a surface thereof, and a lip raised above the surface thereof, which opening has a pair of opposed edges, and a closure device therefor, said closure device comprising: a cap member having an upper part and a threaded lower part, a sealing member of an overall size and shape sufficiently large to cover the opening, said cap member passing through a central portion of the sealing member such that the lower threaded part thereof is located below the sealing member, the threads of the threaded cap member being of a size such that they threadedly engage the said opposed edges of the opening, said sealing member positioned to abut said lip, thereby restricting lateral movement of said cap member, said upper part of the cap member comprising means for cooperating with the sealing member to urge the same into tight sealing engagement with the top of the can to cover the opening as the said lower threaded part is threadedly tightened into the opening.
Claim 10
Dependent Claim
172 words
In combination, a container having an opening in a surface thereof, and a lip raised above the surface thereof, which opening has a pair of opposed edges, and a closure device therefor, said closure device comprising: a cap member having an upper part and a threaded lower part, a sealing member of an overall size and shape sufficiently large to cover the opening, said cap member passing through a central portion of the sealing member such that the lower threaded part thereof is located below the sealing member, the threads of the threaded cap member being of a size such that they threadedly engage the said opposed edges of the opening, said sealing member positioned to abut said lip, thereby restricting lateral movement of said cap member, said upper part of the cap member comprising means for cooperating with the sealing member to urge the same into tight sealing engagement with the top of the can to cover the opening as the said lower threaded part is threadedly tightened into the opening.
Claim 11
Dependent Claim
86 words
The invention of claim 8 wherein said sealing member comprises: a support having a bore completely therethrough for receiving and positioning said threaded lower part and being engaged along the upper surface thereof by a lower surface of the said upper part of the cap member and; a resilient sealing material having a bore completely therethrough for receiving said threaded lower part, and engaged by said support member, and compressed thereby when the threads of said threaded lower part engage the opposed edges of the opening.
Claim 12
Dependent Claim
16 words
The invention of claim 9 wherein said cap member and said support are of integral construction.
Claim 13
Dependent Claim
30 words
The invention of claim 8 wherein a surface of said sealing member contacting the surface of the container is substantially the same overall shape as the shape of the opening.
Claim 14
Dependent Claim
21 words
The invention of claim 8 wherein a surface of said sealing member contacting the surface of the container is substantially circular.
Claim 15
Dependent Claim
