  • Patent number: 4925034
    Abstract: A fitment for a package is stamped out of polystyrene strips and then hot melt adhesive bonded to the package so that a tab portion of the fitment overlies an openable flap formed by a score line in the package. The package is opened by rotating the tab so that the forward portion of the tab pushes the openable flap into the container. Since the forward portion of the tab is adhesively bonded to the openable flap, when a frangible connection between the tab and base fractures, the openable flap and tab can be removed to thereby expose an opening in the package. Rotation of the tab is initiated by pushing downwardly on the forward portion of the tab in order to fracture the score line of the package.
