ABSTRACT:
A disposable lid for pans, pots and other receptacles, particularly advantageous for use in ovens, comprising a plurality of layers of flexible material the outer of which is a foil and the inner of which is a thin film of plastic, known as a food service film, having the property to per se releasably attach to the surface of an article on a light pressured contact therewith. The lid is simply created by bringing sheets of the respective materials of its plurality of layers to a superposed contacting relation and applying thereto a relatively light pressure and tension causing the facing surfaces of such sheets to substantially coextensively contact and attach under conditions of ambient temperature and without application of intervening adhesive material. Simple apparatus facilitating the production of the lids in a kitchen, as, when and in a form required, comprises a receptacle accommodating or formed to provide means defining separate compartments each receiving a supply of a different one of the materials of the respective layers of material of the lid in sheet form, bearing means to which the sheets of material are simultaneously drawn from the respective compartments, under tension, to be applied thereto in a superposed contacting relation and per se be pressured thereby to produce a unitized layered structure, and means for separating said layered structure into segments each of which comprises a single lid.
