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 particular suited for transport and storage of fresh foodstuffs comprising:
a tray, said tray having a base with an upwardly extending wall and a flange extending outwardly from a top portion of said wall opposite said base, said tray constructed of an essentially gas impermeable material;
a cover, said cover having a generally closed top with a downwardly extending wall and a flange extending outwardly from a bottom portion of said wall opposite said top, said flange defining a tongue configured to press-fit into engagement with said upwardly extending wall of said tray, said top of said cover divided into a least two compartments, at least a portion of said top at one of said compartments defining a recessed area, an opening located in said cover at said recessed area and said cover defining at least one air passage leading to said recessed area, said cover constructed of an essentially gas impermeable material;
an atmosphere control member comprising a gas permeable membrane, said membrane extending over said opening, said atmosphere control member permitting gas to flow therethrough into and out of said container when said membrane covers said opening; and
a packaging label connected to said top of said cover and extending over said recessed area, thereby obscuring said membrane from view, but not blocking said at least one air passage, whereby air may flow between said exterior of said container and said atmosphere control member at said recessed area when said label is connected to said cover.
2. The container in accordance with claim 1 wherein said tray is constructed of a generally opaque material and said cover is constructed of a generally transparent material.
3. The container in accordance with claim 1 wherein said top of said cover is divided into at least three compartments.
4. The container in accordance with claim 1 wherein said tray and cover, when connected by pressing said tongue into an inset portion of said base defined by an upwardly extending wall, substantially seal said container without additional sealing means.
5. The container in accordance with claim 1 wherein said at least one air passage comprises at least one slot formed in said top of said cover.
6. The container in accordance with claim 1 wherein said recessed area comprises a depressed portion of said top of said cover relative to at least one adjacent raised portion of said cover and said at least one air passage comprises a slot formed in said at least one adjacent raised portion of said cover.
7. The container in accordance with claim 1 wherein said recessed area comprises a generally four-sided depressed area within a surrounding generally four-sided raised portion of said cover and said at least one air passage comprises a slot formed in each of said four sides of said raised portion of said cover.
