Abstract
A vent system adapted to be installed on a standard container, in place of a shipping and storage plug, for use in venting the container without requiring any modification to the container. The vent system includes a knob which is turnable in one direction to place the vent system in a vent closed condition, as for example for shipping the container, and turnable in the opposite direction to place the vent system in a vent open condition to permit air to be vented into the container during fluid removal. A vent housing is adapted to be screwed into a threaded opening of the container. The knob includes a cap and a ring which are held together by a tamper evident seal. The knob is captured by the vent housing to prevent unwanted removal of the knob and to prevent unwanted access to the container. The tamper evident seal must be removed for access to the vent housing and for removal of the vent system from the container. An alternate embodiment has provisions for preventing leaking of fluid from the container through the vent system in the event the container is tipped.
