Abstract

A container or package which is particularly adapted for disposable single use in the packaging of products such as, for example, food, where the container may be filled with a portion of the product suitable for a single serving and capable of being consumed from the package. The container is formed from a single paperboard blank which is cut and scored so that it may be folded into a cup-like, or dish-like, body shape which is leakproof and which has an edge flange or margin to which the margins of a cover film may be secured.

Claims

1. A container having the general shape of a bowl which is fabricated from a single blank of flexible paperboard material, saiD blank being cut and scored to provide in the set-up container a bottom wall forming panel and a plurality of upwardly and outwardly slanted side wall forming panel portions which are integrally connected to the bottom wall forming panel on straight hinge lines defining the perimeter of said bottom wall forming panel, each said side wall forming panel portion having an upwardly bowed score line at the bottom which provides a flat surface bottom side wall panel area which extends a relatively short distance above said hinged connection with the bottom wall forming panel and merges into the curved top area of said panel portion, said side wall forming panel portions being connected to each other at adjoining ends by integral triangular web portions, each of said web portions being connected to the end edges of a pair of side wall forming panel portions on hinge lines which form an outwardly opening V configuration, said web portions each extending from the hinge line along which the associated side wall forming panels are connected to the bottom wall forming panel to the top edges of said side wall forming panels and terminating at said top edges, said web portions being folded and secured between overlapping end margins of said pair of side wall forming panel portions, said side wall forming panel portions each having at the top edge a relatively narrow out-turned rim forming member which is hingedly connected to the top edge thereof, said rim forming members each having an end section which is overlapped and adhered to a like section of an adjoining rim forming member so as to form a relatively narrow continuous top edge reinforcing rim thereon which is outwardly and downwardly inclined, with said side wall forming portions and said rim forming portions both having continuous curved surfaces extending in the direction around the perimeter of said container and which are held under stress thereby imparting substantial rigidity to the container.
