Abstract:
A filter container comprises a top cap, and a bowl formed of a rigid material. The top cap includes a top cap flange that includes a first path around at least a portion of the top cap flange. The bowl includes a bowl flange that includes a second path around at least a portion of the bowl flange. At least one of the first path and the second path include a reduced thickness of material by comparison with surrounding material. The first path is at a different radial distance from a central axis of the filter container than the second path around the extent of both the first path and the second path, such that exerting a force on an opening member creates a tear through the top cap flange and bowl flange, the tear forming between the first path and the second path and allowing opening of the filter container.
