  • Patent number: 4676394
    Abstract: A carton for receiving and sealing an inner bag is provided. The carton, for example a cereal box, includes flexible tabs thereon oriented to engage a sealing fold selectively formed in a flexible bag received within the container. In the preferred embodiment, the flexible tab is formed by rupturing a portion in the sidewall of the container, along a tear-line provided therein. In an alternate embodiment, the flexible tab is formed from a modified flap mounted on an upper edge of the container. In still other alternate embodiments, containers with multiple flexible tabs for clamping an inner received bag shut, are presented. In all embodiments, the flexible tab or tabs provide clamping shut of the internally received bag by generally pinching a sealing fold, formed in the bag, between the tab(s) and an inner wall of the container.
