description 1,221,322. Vacuum cleaner bag closures. CONSOLIDATED FOODS CORP. 15 Feb., 1968 [15 Feb., 1967; 6 March, 1967 (2); 28 March, 1967; 21 April, 1967], No. 7491/68. Heading B1T. The end closure member 13 for a vacuum cleaner dust bag 10 comprises a plate member (e.g. of cardboard) having a plurality of flaps such as 14 biassed to the closed position by resilient strip member such as 31a, 31b. Thus the flaps snap shut when the suction tube S is removed. As described, the resilient member may be a slitted rubber band 31. The plate member may comprise two cardboard layers 15, 16 sandwiching the resilient member. A production line for assembling the device is described. Figs. 20, 21 (not shown).
