  • Patent number: 4099665
    Abstract: A reclosable carton having opposing side and end walls, the upper portions of the end walls being displaceable inwardly so that the uppermost edges of the side walls may be juxtaposed to form a tapered top closure, a closure flap being hingedly connected to the uppermost edge of one of the side walls, the closure flap being foldable over the uppermost edge of the opposite side wall and releasably secured in the folded over condition to form a tight reclosure. When provided with a liner, the upper end of the liner extends above the uppermost edges of the side walls, and is pinched therebetween when the edges of the side walls are juxtaposed, the folding over of the closure flap serving to automatically enforce the folding of the liner mouth over the uppermost edge of the opposite side wall, thereby providing a tight reclosure for the liner as an incident of reclosing the carton.
