  • Patent number: 4660735
    Abstract: A re-closable container having a beadlike thickening (3), which is enclosed by the bent-down skirt of the inwardly depressed cap, has a collar (4) immediately beneath said thickening, under which an inside flange (12) on the part (11) of the bent skirt outside the container engages, when the cap is depressed down over the brim of the container. Weakening grooves (10) and (15) makes it possible to tear-off the part (11) of the cap with its flange (12), so that the cap can be lifted up from the container. To facilitate the tearing-off the outside part of the cap may have a narrow slot (14), which adjoins as well a circumferential weakening groove (10) as another one (15) reaching from the former and down to the free brim of the cap's skirt. When e.g. a table knife is inserted through the slot, the cap part (11) can be broken along the weaking groove (15), after which said part with its belonging flange easily can be torn-off.
