Abstract: A ventilated plastic bag particularly adapted for carrying hot food from fast food restaurants includes the following components. Front and rear wall sections are connected together to define a closed bottom area and an open top area. A handle or handles are provided in the top area and include a cut out of the front and rear wall sections creating reduced strength regions with resulting high potential for carrying around at least part of the cut out. Closely spaced micro-perforations extend through the wall sections in at least a major portion of the plastic bag other than the reduced strength regions to provide ventilation to an interior food carrying area of the plastic bag while not further weakening the reduced strength regions and increasing the potential for tearing of the bag.

Abstract: A system for forming and mounting end closures for peel-top containers, each closure including a peelable sealing membrane, with a folded pull tab, and a separate plastic overcap. The individual sealing membranes are cut from a continuous web and deposited directly on the open ends of cans or containers being fed in a continuing line. Each membrane is retained in properly oriented association with the corresponding container, by adhesive tacking or through a partial vacuum generated within the container, until such time as the container supported membrane is engaged by a chuck to effect a positive sealing of the membrane to the container. After a sealing of the membrane to the container, the container proceeds through a cycle wherein the tab on the membrane is laterally bent, the overcap is applied, and the container with completed end closure is discharged.
