摘要： A package for storing oxygen sensitive goods includes a first web in the form of a tray which may include flanges, a valve or valves, carbon dioxide, a good or goods, such as red meat or other oxygen sensitive food and non-food products and a second web sealed to the tray in the form of a gas impermeable film to which has been fitted a one-way valve. The pressure within the package increases as a gaseous modified atmosphere is introduced through the one-way valve in the tray. The oxygen within the barrier bag is forced out of the one-way valve located on the film. A vacuum applied to the one-way valve on the film facilitates the removal of oxygen. Additionally, the atmosphere within the bag can be monitored by locating sensors within the gas stream leaving the one-way valve in the film as it leaves the interior of the package.

摘要： Disclosed are an apparatus and method for cutting and sealing a plastic film. The plastics film is conveyed to a sealing area which contains a sealing wire in a housing over which the plastics film is draped out of contact with the wire. The wire is preheated to a first temperature and is then heated to a second higher temperature while a differential pressure is applied to the film biasing it towards and into contact with the wire which cuts and heat seals it. By providing the heat sealing area in the outer periphery of a rotatable drum to which a continuous film is conveyed, a continuous cutting and heat sealing process can be achieved.

摘要： A domed container for the preparation and display of food includes a receptacle, a dome cover, and a hollow mold member. The receptacle has a bottom with a top surface and an outer circumference. The bottom possesses at least one groove in a closed, continuous pattern. The groove has two side surfaces and a bottom surface, and each side surface is configured to include projections extending into the groove. The dome cover includes a top wall having at least one wall depending therefrom. The depending wall has an outside surface and an inside surface. The container possesses a locking structure for releasably locking the cover to the receptacle. The hollow mold member, which forms a closed continuous pattern, has a lower edge that fits into the groove of the receptacle and is held in place from each side by an interference fit between the projections of the side surfaces of the groove and the lower edge, thereby removably attaching the hollow mold member perpendicularly to the receptacle.

摘要： A soft, flexible, low-density, open-cell, thermoplastic, absorbent foam formed from a foam polymer formula including a balanced amount of a plasticizing agent and a surfactant in combination with a base resin. Thermoplastic elastomers can be added to the foam polymer formula to improve softness, flexibility, elasticity, and resiliency of the resulting foam. The surfactant may be either a single surfactant or a multi-surfactant system. The foam possesses a number of qualities, such as softness and strength, which render the foam particularly suitable for use in a variety of personal care products, medical products, and the like.

摘要： A microwavable container useful in the microwave heating of items, particularly foodstuffs, comprises readily separable components. An outer shell which will remain relatively cool and, therefore, capable of being handled, surrounds an inner shell capable of sustaining high temperatures. A consumer may heat a food product in the inner shell of the present invention without risking contact with that inner shell when the inner shell becomes hot. After use, the components are readily separable for separate recycling processes.

摘要： An apparatus and method for the determination of the flow properties of thermoplastic materials in admixture with volatile liquids or other additives comprising an extruder which is employed to melt the polymer and admix therewith volatile blowing agents or additives. Subsequently the molten mixture is injected into an extrusion plastometer or rheometer for extruding the mixture, while still in molten form, through a capillary orifice in the extrusion plastometer. When volatile liquid blowing agents are admixed with the molten polymer in the extruder, an adjustable linkage is provided interconnecting the plastometer and the extruder whereby the pumping rate of the blowing agent can be variably adjusted and the blowing agent positively injected into the molten polymer within the extruder by the reciprocal motion of a piston means employed in the extrusion plastometer.
