Abstract
There is provided a container having a container with open end, and a bottom cap has a sealant material bonded thereto to provide a hermetic seal between the bottom cap and the open bottom of the container and a grip surface through or slightly beyond the exterior surface of the bottom cap to contact a substrate, such as a table.
Claims23
A bottom cap for closing and hermetically sealing the open bottom end of a container, the bottom cap comprising:
- a bottom wall having a peripheral portion;
- a side wall extending upwardly from said peripheral portion, said side wall having means for securing said bottom cap to the bottom end of the container;
- and
- a continuous layer of sealant material bonded to said peripheral portion of said bottom wall, said sealant material being adapted to envelop the bottom end of the container forming a hermetic seal when said bottom cap is secured thereto.
1 more element
A container assembly, comprising:
- a container having an open bottom end with a downwardly directed sealing surface having an inside surface and an outside surface, and means for securing a bottom cap to said bottom end;
- a bottom cap for closing and hermetically sealing said bottom end, said bottom cap having a bottom wall and an upstanding peripheral wall having means for securing said bottom cap to said-bottom end;
- and
- a continuous strip of compressible sealant material bonded to said container assembly, said strip being between said sealing surface and said bottom wall so that when said bottom cap is secured to said bottom end, said sealing surface compresses said strip against said bottom wall thereby enveloping said sealing surface, said inside surface and said outside surface forming a hermetic seal between said sealing surface of said container and said bottom cap.
1 more element
A container assembly, comprising
- a container having a threaded cylindrical bottom end with a downwardly directed sealing surface having an inside surface and an outside surface;
- and
- a bottom cap for closing and hermetically sealing a bottom end, said bottom cap having a bottom wall with a peripheral portion, and a threaded upstanding cylindrical peripheral wall for threadedly securing said bottom cap to said bottom end of said container, said peripheral portion of said bottom cap having an annular layer of compressible elastomeric sealant material fused thereto, said sealant material having a Shore A Hardness from about 30 to about 60, and said layer being adapted to be compressed by and thereby enveloping said sealing surface, said inside surface and said outside surface forming a hermetic seal with said sealing surface when said bottom cap is threadedly secured to said bottom end of said container.
