Atmosphere controlled packaging for fresh foodstuffs
An atmosphere controlled, resealable foodstuff container includes a base tray and a cover. The cover and base tray are constructed of a substantially gas impermeable material. The cover and base tray include resealing members. When connected, the cover and base tray define a generally enclosed and sealed interior space for foodstuffs. The container includes at least one atmosphere control member, such as a membrane, which controls the flow of gases through an opening in the container. The member may be located over a recessed opening in the cover to permit the containers to be stacked without gas flow interference. A label extends over the recess, thus obscuring the membrane from view to the purchaser without affecting the membrane atmosphere control function. The base tray may be opaque for use as a serving tray and the cover transparent to permit viewing of the product.
1. A container for foodstuffs comprising:
a cover, said cover having an inner surface, an outer surface and a peripheral edge, said cover defining at least two compartments, said cover having an opening therein and said cover otherwise defining an essentially gas impermeable member, said cover further defining a first locking member;
a generally gas impermeable sealing film applied to said cover and extending over said at least two compartments to define a generally enclosed interior space with said cover;
a base tray, said tray having an inner surface, an outside surface and a peripheral edge, said inner surface being generally concave and said base tray comprising an essentially gas impermeable material, said base defining a second locking member, said base connected to said cover such that said sealing film is located between said cover and base, said cover and base connected to one another via engagement of said first and second locking members; and
an atmosphere control member closing said opening in said cover, said atmosphere control member configured to permit gas to flow through the interior area of said container when said atmosphere control member covers said opening, and wherein said opening is defined in a recessed area of said cover, said cover defining one or more air pathways leading to said recessed area and further comprising a packaging label located over said recessed area, whereby said packaging label is positioned over, but spaced from, said atmosphere control member so as to obscure said atmosphere control member, but whereby air may flow through said one or more air pathways to and from said atmosphere control member.
2. The container in accordance with claim 1 wherein said compartments are outwardly extending areas of said cover.
3. The container in accordance with claim 1 wherein said opening is located in one of said compartments.
4. The container in accordance with claim 1 wherein said base tray is constructed of an opaque material and said cover is constructed of a transparent material.
5. The container in accordance with claim 1 wherein said first locking member comprises an upstanding wall and said second locking member comprises a tongue member which may be press fit into engagement with said wall.
6. The container in accordance with claim 5 wherein said tongue extends downwardly from said cover and said wall extends upwardly from said base tray.
