Abstract: A tamper indicator includes a first indicator element coupled to a first cylindrical element, a second indicator element positioned within a second cylindrical element and displaceable between a first position spaced apart from the first indicator element and a second position contacting the first indicator element. The first indicator element changes visual states when it contacts the second indicator element. A biasing device biases the first indicator element toward the second indicator element. A locking system maintains the first and second indicator elements in a locked, spaced apart configuration while the first and second cylindrical elements remain in a first location. The locking device enables relative movement to occur between the first and second indicator elements after the first and second cylindrical elements have been displaced from the first position into a second position.

Abstract: A bulk material container with a vent. Disposed in the vent is a filter membrane. Under normal conditions, fluid in the container breathes with the air under atmospheric pressure through the filter membrane. In one embodiment, when the bulk material in the container is under excessive fluid pressure, the filter membrane is fractured for fluid under excessive pressure to vent rapidly to atmosphere. In another embodiment, when there is an excessive vacuum in the container, air under atmospheric pressure fractures the filter member for air atmospheric pressure to instantaneously enter the container through the fractured membrane to reduce the vacuum within the container.

Abstract: In combination, a container and a linerless cap and a method of forming the cap. The cap includes plastic and has a sealing surface which is softer than contiguous plastic portions as a result of its method of forming which includes stretching. In the method the cap is molded from plastic and includes a top wall, an outer depending skirt and an internal depending substantially annular wall having an upper end integral with and depending from the top wall and a lower free end. Thereafter the free end is engaged by a forming tool to progressively turn the free end away from the internal wall to create a stretched intermediate portion for sealing which is softer than its contiguous portions.
