Abstract

An improved package is provided which is formed from a blank of rigid material, such as cardboard, and an internal lining of plastic material, with the rigid blank including a bottom wall and a plurality of side walls. The internal lining extends over the top edge of the side walls and along the exterior walls of the package to define an exterior lining. The free edge of the exterior lining includes a flange extending in a direction outwardly from the side walls of the package. In addition, extension flaps of one package are operable to act as a stop and engage a portion of another package nested therewith to prevent the nested packages from being wedged within each other.

Claims

1. A package formed from a blank of rigid material, said blank including a bottom wall and a plurality of side walls and extension members extending outwardly from portions of said side walls, a lining of plastic material lining the internal walls of said package, said internal lining extending over the top edge of said side walls, said lining further extending along a portion of the exterior of the side walls of said package and along said extension members to define an exterior lining, said exterior lining further including a free edge defining a flange extending in a direction outwardly from the side walls of the package, said extension members reinforcing said flange and being operable to act as a stop for one part of the package and said flange being operable to act as a stop for another part of the package and engage a portion of another package nested therewith to prevent said nested packages from being wedged within each other.

2. A package according to claim 1 wherein said extension members include extension flaps folded outwardly and downwardly toward the exterior of the side walls of said package, said exterior lining extending along said extension flaps and including said free edge defining said flange, the strength of said flange being reinforced by said extension flaps.

3. A package according to claim 1 wherein said plastic lining is adhered to said rigid blank by binding agent.

4. A package according to claim 1 wherein one or more of said side walls include embossed portions operable as said extension members to facilitate the separation of nested packages.

5. A package according to claim 1 wherein said plastic lining is a polyvinyl-chloride foil of a thickness in the range of 0.10-0.15 mm.
