Abstract
947,341. Container closures; portable containers. REYNOLDS METALS CO. July 10, 1961 [July 11, 1960], No. 24904/61. Headings B8D and B8T. A lid 20 for a receptacle 10 e.g. a cup, having an open end with a peripheral outwardly extending lip 15, consists of a sheet of metal, e.g. aluminium, foil having a peripheral wall 27 terminating in an outwardly curled stiffening bead 28 for engagement under the lip 15, the inner circumference of the peripheral wall at the locus where the bead curls outwards being normally slightly smaller than the circumference of the receptacle lip 15 and the bead being resiliently deformable so as to pass over the receptacle lip. The bottom portion 21 of the lid is embossed with an ornamental pattern 22 and has an opening 23 to allow egress and inflow of air from and to the receptacle when the lid is put on and removed. The displaced metal from the opening 23 forms a flange 23a round the underside of the opening and helps to prevent loss of liquid through the opening of which the diameter is from 0.03 to 0.07 inch. The foil from which the lid is made is preferably between 0.001 and 0.0025 inch thick and can be indented by means of a pencil to indicate the nature of the contents of the receptacle. After removal from the mouth of the cup the lid may be used as a saucer. The cup may have flexible walls and may be made of thin, impact extruded synthetic plastic material or of a foamed synthetic plastic material. Specification 947,342 is referred to.
