Abstract: A vented liquid containment device has a cup member located within the structure of a threaded cap so that a filter material can be placed within the cup member to prevent liquids from being splashed in an upward direction into contact with a vent that is formed within an inside portion of the cap. When used in conjunction with a marine vessel, rough water can cause oil within an oil reservoir to splash upwardly and come into contact with the vent opening which is intended to allow air and other gases to pass back and forth between the cavity of the reservoir and the atmosphere. The presence of the filter material prevents the liquids from being splashed into direct contact with the vent openings which could otherwise allow oil to spill outwardly onto surfaces of the reservoir and nearby components.

Abstract: For use in medical trays the filtering flat material (2) has to be such that no micro-organisms can penetrate through it. In order to arrange such a filter (1) for achieving closure of a tray's partial surface including through openings which ensures sterility, a closed sealing line, which surrounds the through openings, is formed in the area of each flat partial surface having through openings, along which two tray parts to be assembled and including co-operating clamping surfaces enable clamping the seal (3) of the filter (1). By the elasticity of the seal (3) sufficiently good closure is ensured even by small clamping pressure and even with not precisely plane clamping surfaces. The bond of the seal (3) to the filtering flat material (2) has the additional advantage that the filter (1) can also be arranged at a lower surface by pressing its seal (3) into a corresponding groove and does not loosen due to gravity.

Abstract: A package for maintaining a modified atmosphere around contents being contained therein when stored in an ambient environment is set forth. The modified-atmosphere package includes a tray, a membrane, and a structural member. The tray has a base and side walls extending upwardly from the base. The side walls and the base define a cavity wherein the contents are disposed. A membrane is attached to a top portion of the side walls and encloses the cavity. The structural member is detachably connected to the top portion of the side walls and is disposed above the membrane to prevent the membrane from contacting an external structure which inhibits permeation through the membrane. The structural member also has at least one opening for exposing the membrane to the ambient environment. Stacking means at the base of the tray and the top of the structural member allow the modified-atmosphere packages to be easily stacked.
