Abstract: A plastic can is formed of a body member including a content protecting layer which is a tubular body formed by folding back and outward one side edge of a laminated film, bonding the folded parts such that air bubbles are not entrapped thereunder, overlapping the other side edge of the same laminated film on the bonded surface and bonding the side edges such that air bubbles are not entrapped between the side edges. An additional sheet is bonded all over the external surface of the laminated film except for a projecting stripe formed by the bonding of the side edges. A surfacing plastic layer covers the additional sheet and the projecting stripes. An apparatus is provided for forming the can, smoothing the surfacing plastic layer, forming the tube into can bodies, shaping the can bodies and sealing, lids on the ends of the cans.

Abstract: An integrally molded plastic holder for tape cartridges is provided wherein the holder is partitioned into an upper section and a lower section by two spaced apart ledges integrally formed therewith and wherein the upper and lower sections have a plurality of compartments dimensioned to receive a tape cartridge and wherein a plurality of resiliently tab portions are mounted between the upper and lower ledges so that a portion of each tab portion is located in a recess in a tape cartridge when the tape cartridge has been inserted into one of the compartments to restrain the removal of the tape cartridge from the compartment. The tab portions are mounted so that, when the tab portions are in the recesses, they are in an unstressed condition.

Abstract: A bottle closure cap stampable from sheet metal as a shallow cylindrical inverted dish having a rounded juncture forming a fillet between its crown and its cylindrical wall; a layer of elastomeric material being disposed in the fillet and engageable with the axial end of the bottle when the cap is attached. A generally radially extending rip tab is integral with the cylindrical wall at the bottom edge thereof and is adapted to tear through the cylindrical wall by a generally circumferential pull of the user to gain access to the container. A rip line is provided commencing at a corner defined by the bottom edge of the cylindrical wall where it meets the rip tab. At least one groove is formed in the rip tab extending in the inner surface of the side wall. The rip line extends at a shallow angle across the cylindrical wall, without crossing the groove, continuing to a level which is spaced below the crown, continuing parallel to the crown circumferentially about half-way around the closure cap.
