Abstract: An apparatus for promoting circulation through a subcutaneous lymph vascular network may comprise a first manifold layer, a second manifold layer coupled to the first manifold layer, and a cover layer coupled to the second manifold layer. The first manifold may have a first stiffness, and the second manifold may have a second stiffness greater than the first stiffness. In some embodiments, the apparatus may additionally have a fluid interface configured to fluidly couple at least one of the first manifold layer and the second manifold layer to a fluid conductor through the cover layer. The fluid conductor may be coupled to or configured to be coupled to a source of negative pressure.

Abstract: A tray-like container is disclosed having an open compartment for containing articles therein when shipped. The container includes a top surface with a first downwardly depending well defining a female element, and a second downwardly depending well within the compartment bottom, laterally offset with respect to said first well defining a male element. When formed into a display structure a base having an inclined top surface is employed. Within the inclined surface is disposed a well defining a female element engageable with the male element of a container stacked thereon. The nestable engagement of the male and female elements of stackably tiered containers engaged with the inclined base form a unitary display structure wherein the articles contained within each container are accessible.

Abstract: Containers of the open top can type are closed and sealed by a closure system comprising an inner lid of thin material such as plastic film and a stiff outer cover which grips the container and bears down on the inner lid flange to hold it securely in closed, sealing position. Optional provision is made for the escape of air during insertion of the inner lid and retention of the lid in position pending application of the outer cover.
