A package for containing food products has at least two compartments having different atmospheric conditions. Each of the compartments may be sealed by a membrane having different permeability. The membranes may be sealed to a peripheral flange extending around each of the compartments. The peripheral flange is designed to facilitate severing in place on the tray of a membrane from a continuous web of material.

A sealable multicompartment container comprises a first inner compartment surrounded by a second compartment in the form of an annular trough, both compartments having upper edges for sealing with a closure lid and being joined by a folded wall member pliable to permit unfolding, thereby extending the container depth and merging the two compartments.
A drawer insert, in particular a cutlery insert, which may be adapted to different drawer sizes. The drawer insert comprises a plurality of separate trays (6, 7) each delimiting a receiving space. At least one of the trays (7) is compressible in a resilient manner. The trays (6, 7) are surrounded by a frame (8) whereof lateral delimiting struts (9) are compressible in a resilient manner.
A plastic food storage container includes a container body having a bottom and a peripheral wall, an upper end of the container body having a peripheral rim; a lid having a peripheral edge adapted to matingly engage the peripheral rim; a region of the lid having a lifting tab extending outwardly from the peripheral edge, and a vent located in the region.

An apparatus for supplying one or more gases, such as oxygen, to a target area, comprising a top layer and a bottom layer sealed around the perimeter of the layers to form a reservoir between the layers, wherein the top layer is not gas-permeable and the bottom layer is highly gas-permeable, said reservoir containing one or more gases. The present invention also describes methods of using such an apparatus to supply oxygen to a wound for improved wound healing.
