Abstract

1418472 Tear-off pad of plastics film articles such as bags BRITISH VISQUEEN Ltd 6 March 1973 [24 March 1972] 13862/72 Heading B8C A tear-off pad of plastics-film articles, such as bags 1, having an aperture in an edge portion 2 thereof and a stud 5 passing through the aperture is characterized in that the articles are heat-sealed to one another and, in the same region, collectively to the stud around the aperture. As shown, each bag 1 in a stack of identical bags has a front wall mouth edge 3 and a lip extension 2 of the back wall provided with a tear line 4 and a pair of openings each of which receives a stud 5 bored at 6 to accommodate a pin of a dispenser, the bags being heatsealed to one another and to the stud 5 in each region 7, Fig. 2. In a device for forming a pad a stack of bags 15 is clamped to a plate 14 and the latter is lowered to press the stack 15 against a plate 11 and, simultaneously, press a stud 5, mounted upon a spring-loaded plunger 9, wholly within an aperture 10 in the plate 11. A heated punch 12 is then driven through an aperture 13 in the plate 14 and through the stack of bags to melt and displace the plastics material to form an aperture in the stack, and depress slightly the stud 5. The punch 12 is then withdrawn followed by the stud 5, which, driven by the plunger 9, is pushed through the aperture in the stack until a flange 8 on the stud 5 abuts the underface of the stack 15, the the stud becoming sealed within the aperture as the molten plastics cools. The studs may be solid and be provided with hooks for suspending packs of supermarket bags; the bags being advantageously formed of polyethylene film, and the studs of polyethylene itself. The stud may be made of other material such as cellulose fibres, paper, or wool, and could be formed in extensions along the bottom, or side, edges of the bags.
