ABSTRACT:
A refrigerator container for food. The container includes a receptacle portion comprising a plastic which is resistant to flexing and a lid for sealing the container. The lid has an inflexible portion which comprises a material having the same shrink properties as the receptacle and a resilient portion, the inflexible portion including a peripheral flange which extends parallel to the inner surface of the mouth of the receptacle portion, the outer surface of the peripheral flange being substantially the size of but slightly smaller than the inner surface of the mouth of the receptacle portion. The resilient portion of the lid includes a peripheral flange that fits about and closely adjacent the outer surface of the peripheral flange of the inflexible portions so that when the lid is used to close the container there is a tight fit between the lid and the mouth of the receptacle as the flange of the inflexible portion is urged against the flange of the resilient portion. The inflexible portion of the lid has the same shrink characteristics as the receptacle portion so that a tight fit between the lid and the receptacle at room temperature remains tight when the container is placed in a refrigerator.
