Two cover portions are pivotally mounted on the base and have lower edges with inwardly directing flanges interfitting with the rim of the base to seal the cover portions to the base. The cover portions seal to one another by structure such as a tongue and groove joint, and structure is provided for releasably holding the cover portions in closed position.

Abstract: A rigid container is made by injection molding a parison having plural layers of polymers. The parison is blow molded to the final shape of the container. Control during injection is exercised over each of the plural polymers so as to produce uninterrupted layers extending throughout the walls of the parison and to insure that the interior layers are completely encapsulated within the outer layers.

Abstract: An inexpensive, disposable, three-dimensionally contoured container, suitable for many purposes including holding food during exposure to high temperatures for long times in either a microwave or a conventional oven without any detrimental effect to the container or the food. The container consists of an essentially impervious liner of polyethylene terephthalate directly bonded by its own substance to a pre-formed contoured base obtained by molding to final shape nonbrowning substantially 100% bleached kraft wood pulp from an aqueous slurry thereof against an open-face suction mold, and drying the same under pressure imposed by a mating pair of heated dies. The liner is formed by bonding to the pulp base a 0.5-2.0 mil thick film of thermoformable, substantially amorphous, substantially unoriented polyethylene terephthalate having a molecular weight which is understood to be in excess of 15,000.

Abstract: A method of purveying food in which a variety of foods are cooked and frozen in disposable containers of ovenable sheet material each having a mouth surrounded by an outstanding lip and preferably a removable cover. At the time of serving, a plurality of the containers of frozen food are selected, to make up a meal, and a serving assembly provided by placing them in inverted position on an ovenable serving plate having a retaining rim, with the lips of adjacent containers overlapping each other or abutting the rim and to form a base that seats on the plate surface. The assembly is then heated to eating temperature and placed before the diner and the containers removed to display the foods as a normal serving. An aspect of the invention is the ovenable assembly of filled containers inverted on a serving plate having a retaining rim.

Abstract: A process for preparing a retort-proof laminate for packaging foodstuffs which comprises laminating an aluminum substrate to at least one polyolefin film selected from the group consisting of high density-polyethylene, polypropylene, ethylene-propylene copolymers and polybutene films using as an adhesive a specific polyolefin resin in melted state prepared by combining together (A) at least one member selected from the group consisting of high-density polyethylene, polypropylene ethylene-propylene copolymers and polybutene, (B) maleic anhydride and (C) aluminum hydroxide, and by rendering said specific polyolefin resin substantially free from unreacted maleic anhydride and low molecular weight maleic anhydide homopolymers.The process also includes preparing a retort-proof coated aluminum substrate for packaging foodstuffs which comprises coating an aluminum substrate with a layer formed from the above-described specific polyolefin resin and thereafter forming a suitable retort packaging container therefrom.

Abstract: A container for packaging frozen food in which the food can be reheated including a paperboard tray having upstanding side walls and horizontal flanges and an upright central divider wall forming separate food compartments in the tray. The container is formed from a planar die-cut blank in which the central divider wall is formed by folding adjacent rectangular panels on the blank into abutting, back-to-back relation and the side walls are one piece and are foldably connected to adjacent die-cut portions of the blank so that when the divider wall is erected, the side walls are continguous to each other about the periphery of the tray. A pre-formed, semi-rigid blister of thermoformable plastic material is used in combination with the tray to provide a leakproof liner.

Abstract: A frozen or refrigerated precooked meal formed from a number of food components is packaged in a compartmented tray which is transparent to radiant energy such as that from microwave or infrared energy sources. Each of the tray compartments is defined by ridges and side walls formed integrally with the tray and the different component foods of the meal are disposed within selected different tray compartments. A radiation transparent film is secured over the tray and is bonded to the upper edge of the tray side wall and ridges to seal each compartment. Selected areas of the seals between the film and portions of the ridges and/or tray side walls are weakened so that they may rupture in response to excessive water vapor pressure build up to enable the water vapor to escape. The sealed food tray may be placed in a specially formed shielding box which controls the quantity of radiation to which each of the food components are exposed within a given time.
