One piece, collapsible package

A one piece package containing contents comprising a pre-cooked, frozen lobster hermetically sealed in a boilable plastic bag, said package comprising:

• (a) a generally trapezoidal shaped bottom panel having a central longitudinal crease running the length thereof,
• (b) a first generally rectangular shaped side panel hingedly connected to said bottom panel having hingedly connected end flaps,
• (c) a generally trapezoidal shaped top panel corresponding in shape and size substantially to said bottom panel and hingedly connected to said first side panel, having a central longitudinal crease running the length thereof and having hingedly connected end flaps and a plurality of hingedly connected window flaps which open inwardly to form one or more windows,
• (d) a second generally rectangular shaped side panel corresponding in shape and size substantially to said first side panel and hingedly connected to said top panel, having hingedly connected end flaps, and
• (e) a generally rectangular shaped panel hingedly connected to said second side panel and adhesively connected to said bottom panel;
• said inwardly opening window flaps being pushed by the contents of the package such that their edges contact the side panels, thereby defining fairly rigid inner walls which hold the contents of the package, provide lateral support for the contents in the package and ensure that the contents are centered in the package, and
• said longitudinal creases on said top and bottom panels being parallel to each other thereby allowing the package to be collapsible when the contents of the package are removed and the end flaps are not engaged and further allowing the package to more readily conform to the shape of the contents.
