Abstract: A two-piece container, for sandwiches and the like, having a paperboard base, which includes a central, polygonal, bottom panel of at least four sides; at least four, upstanding, side wall panels, preferably connected to the sides of the bottom panel; at least four, triangular gusset panels, each gusset panel being located between and foldably connected to two, adjacent, side wall panels; and at least two, downwardly extending, base-locking flaps, foldably connected to the top edges of at least two, non-adjacent, side wall panels; the central, leading edge portions of each base-locking flap being adhesively bonded to the underlying surface of a side wall panel; and each of the gusset panels being folded so that it lies substantially flat against a surface of a side wall and is overlain by a base-locking flap. The top edges of each gusset panel are substantially colinear with the lateralmost, lateral edge portions of an overlying, base-locking flap.

Abstract: A process for providing a hermetic, heat-sealed closure for a filled, thermoplastic or thermoplastic coated container by the steps of: providing a continuous web of a thermoplastic material, having a temperature within the drooping and heat-sealing ranges of the thermoplastic material, draped over the mouth of the filled container; urging the web inwardly of the mouth of the container so that the web overlies interior and exterior, thermoplastic surfaces of the mouth of the container; and pressing the web against the interior and exterior, thermoplastic surfaces of the mouth of the container to form a heat-sealed bond, by directing a stream of a gas against an exposed surface of the web overlying a thermoplastic surface of the mouth of the container.

Abstract: A container for packaging fragile items. The container provides an inner carton suspended within an outer carton. The suspension is achieved by means of integral end flaps on the inner carton which interlock the end flaps of the outer carton.
