Abstract
A re-sealable package and method of making the same. The package includes a base having a cavity for receiving an article, and a hinged cover for forming a releasable snap fit closure with the base. A plurality of channels are in fluid communication between the cavity and an upper edge of the base. A volume of gas located within the cavity is removed or otherwise altered through the channels prior to sealing the cover to the base. A slot located adjacent the upper edge of the base provides a path for withdrawing or administering a volume of gas during the gaseous modification, and subsequently receives an extruded portion of the cover to form a lip for forming a releasable snap fit closure.
Claims27
A re-sealable package, comprising:
- a base having a cavity configured to receive an article therein, and a plurality of channels in fluid communication between the cavity and an upper perimeter of the base;
- a cover engaging the upper perimeter of the base;
- a hinge adjacent a side of the upper perimeter, the hinge pivotally coupling the base and the cover;
- and
- a seal at the upper perimeter between the base and the cover, wherein the seal prevents fluid communication through the plurality of channels.
A re-sealable package, comprising:
- a base having a cavity configured to receive an article therein and an upper perimeter, wherein the base includes an outer edge extending along a first side of the upper perimeter of the base;
- a cover engaging the upper perimeter of the base, the cover having a lip, wherein the lip engages the outer edge of the base to maintain the cover in a closed position over the cavity;
- a hinge adjacent a second side of the upper perimeter, the hinge pivotally coupling the base and the cover.
A method of manufacturing a re-sealable package, the method comprising:
- molding a base in a first formable web, the base comprising a base cavity and an upper perimeter;
- removing a portion of the first formable web to form an elongated slot at a first side of the upper perimeter of the base;
- receiving a second formable web above the first formable web;
- molding a cover in the second formable web for engagement with the base, wherein the cover comprises a sealing surface for engagement with the upper perimeter of the base;
- forming a hinge between the first formable web and the second formable web at a second side of the upper perimeter of the base;
- extruding a portion of the second formable web through the elongated slot to form a lip releasably engaging the elongated slot;
- and
- separating the first and second formable webs about a periphery of the re-sealable package.
