An apparatus is provided for venting liquid containers (10), and particularly for venting liquid containers of highly viscous liquids. The apparatus includes a vessel having a threaded neck (14). A cap (12) is suitably dimensioned for screwthreadably engaging the threaded neck. The cap defines an interior cap surface (18). The cap has formed therethrough at least one aperture (20). A mounting member (22) mounts a gas permeable membrane (24). The mounting member is disposed on the interior cap surface in communication with the aperture. A gas permeable membrane is mounted to the mounting member in an angled relation with respect to the interior cap surface and in liquid sealing relation with respect to the at least one aperture. |
