CAP FOR A CONTAINER
First Claim
1. A cap assembly for a container used for holding a liquid that is removed therefrom, said cap assembly comprising:
- a cap defined as having a roof portion, a cylindrical skirt depending from an outer periphery defined by the roof portion, and a well extending from said roof portion into said cap, the well having a wall terminating at a base structure, said base structure having an aperture that is sized smaller than said well; and
a filter sized to frictionally fit into said well section and having a material characteristic of being air permeable and liquid impermeable such that liquid contained within said container is prevented from leaking and air may pass through said filter into the container.

Abstract
A cap assembly for a container used for holding a liquid that is removed from the container, the cap assembly includes: a cap having a roof portion, a cylindrical skirt depending from an outer periphery defined by the roof portion, and a well extending from the roof portion into the cap. The well further has a wall terminating at a base structure, and the base structure has an aperture that is sized smaller than the well. The cap assembly also includes a filter sized to frictionally fit into the well section and the filter is air permeable and liquid impermeable. The cap assembly also includes a seal that has an opening sized to fit over the well and has a diameter substantially matching the internal diameter of the.

6. A cap assembly for use with a container holding a liquid that is removed therefrom:
-
said container comprising; a neck portion surrounding an orifice, a thread positioned about the neck, a tube in fluid communication with said container, such that liquid contained therein flows through the tube when a pressure within the container substantially equals atmospheric pressure; and said cap assembly comprising; a cap defined as having a roof portion, a cylindrical skirt depending from an outer periphery defined by the roof portion, and a well extending from said roof portion into said cap, the well having a wall terminating at a base structure, said base structure having an aperture that is sized smaller than said well, a filter sized to frictionally fit into said well section and having a material characteristic of being air permeable and liquid impermeable such that liquid contained within said container is prevented from leaking and air may pass through said filter into the container, and a corresponding thread positioned on an internal region of said cylindrical skirt to mate with said thread on said neck, whereby air passes through said filter into said container to substantially equalize the pressure within the container and permit the fluid within the container to flow through said tube. - View Dependent Claims (7, 8, 9, 10)
