Abstract
The invention pertains to a method and apparatus allowing for gas flow into and/or out of a container assembly. The container assembly comprises a container having a sealing surface, and a cap having a sealing surface. The sealing surface of the container, the cap, or both is prepared by either being made of a coarse texture or polished so that the sealing surface of the container and the cap may cooperate with one another to form a seal, yet allow gas to flow into or out of the container assembly, as required.
Claims20
A method for controlling gas flow into or out of a container assembly that is comprised of a cap and a container, the container and the cap each having a sealing surface and the sealing surfaces cooperating with one another, the method comprising steps of:
- preparing the texture of at least one of a group consisting of the sealing surface of the cap and the sealing surface of the container, and
- adjusting the texture to allow for a sufficient amount of gas to flow into or out of the container assembly as required.
A container assembly comprising:
- a container including a sealing surface:;
- a cap including a sealing surface;
- wherein the sealing surface of at least one of a group consisting of the container and the cap is prepared to have a desired texture, and wherein the sealing surface of the container and the cap cooperate with one another to allow for a substantial seal and to allow gas to flow into or out of the container assembly as required.
A container assembly comprising:
- a container and a cap;
- the container including a base, and a neck for engagement with the cap, an end of the neck defining a container mouth;
- the neck being substantially symmetrical about a central vertical axis, the neck forming a flexible lip proximate the mouth, with an upper generally frusto-conical exterior sealing surface, the lip having a lower generally frusto-conical interior sealing surface;
- the cap including a top, a skirt depending peripherally from the top, at least one first annular sealing protrusions depending from an interior surface of the top, and at least one second annular sealing protrusion depending from an interior surface of the top;
- wherein, upon engagement of the cap with the neck, the first sealing protrusion sealingly engages the lower interior sealing surface, and the second sealing protrusion engages the upper exterior sealing surface;
- and,
- wherein at least one of a group consisting of the interior sealing surface, the exterior sealing surface, at least a portion of the second sealing protrusion, and at least a portion of the first sealing protrusion is prepared to have a coarsened or polished surface so that gas can flow into or out of the container assembly as required.
