    Abstract: A chamber assembly for testing a valve includes a proximal chamber portion that defines a proximal interior space, and a distal chamber portion that defines a distal interior space. The distal interior space includes a gas space. When a liquid is inserted into the proximal and distal chambers there is an interface between the liquid and a gas in the gas space. A valve holder is disposed adjacent to the proximal interior space and the distal interior space. The valve holder is configured to receive the valve in a bore of the valve holder. A shortest distance between a center of the valve when in the bore and the interface is at least about 45 mm.

    Abstract: A container assembly comprises a container having a peripheral side wall defining a rectangular interior space and having top flap and bottom flaps folded inwardly to selectively enclose the interior space. The bottom flaps include notched edges for interlocking to maintain corners of the peripheral side wall square. An insert is removably receivable in the rectangular interior space. The insert comprises first and second panels of sheet material selectively folded to define a plurality of rectangular mold cavities in the interior space. Distal edges of the panels are notched wherein the notched edges interlock at the corners of the peripheral side wall to maintain the mold cavities square.
