Abstract: The invention disclosed is an intermediate-volume, dimensionally scalable container having a large transmural aperture providing easy access to contents and a resealable lid providing quick and repeated access to the contents. In one embodiment the invention provides a clear visible indication as to the locked or unlocked state of the lid and is adapted to readily incorporate different forms of tamper proof and tamper evident seals. The invention includes an assembly of similar containers of the same or different volumes having recessed bottom portions to receive the upper portion and lid of a vertically adjacent container when stacked and at least two opposing sides having complementary surface deformations to facilitate side-to-side mating of such containers when shipped, displayed for sale or stored.

Abstract: An apparatus and method for using a detachable sealed enclosure for containing and quickly accessing filter elements and the like without the use of tools and without the possibility of initial or subsequent over tightening. A first set of paired protrusions receive lateral pinch forces which draw the enclosure into a sealed connection with a lid while selectively compressing a seal between these components. A second set of paired protrusions receive lateral pinch forces which release the sealed connection, providing access to the enclosure content.
