Abstract:
1. A box formed from a single piece of punched and crease-lined cardboard sheet comprising at least four consecutive main panels and a flap projecting from the first main panel and superposed on and glued onto the last main panel, the main panels and said flap being separated from each other by parallel folding lines, two closure panels for two ends of the box and projecting from ends of at least one of the main panels, at least one tab projecting from one end of at least one of the main panels consecutive to that from which the closure panels project, the closure panels and said tab being, separated from the main panels by transverse folding lines perpendicular to said longitudinal folding lines, a lip projecting from each closure panel and separated from each respective closure panel by a folding line parallel to said transverse folding lines, each lip being inserted into the closed box below a main panel different from those from which the closure panels and said flap project, in the cardboard sheet there being provided cuts which define at least one appendix projecting from at least one closure panel, to leave a corresponding window free within each lip when each lip is folded about the respective closure panel from which each lip projects, there also being provided a knurling which extends along the length of the folding line between each lip and each respective closure panel to define a tearing line along which each lip can be torn away from the respective closure panel, from said tab there laterally projecting a hook-shaped tooth which, in the closed box, projects through the window formed in a first lip to retain the first lip and the respective closure panel in its closed position, wherein from that main panel on the inside of which the first lip projecting from the respective closure panel is positioned, there projects a supplementary tab in which an aperture is provided, said supplementary tab being separated from the main panel from which the supplementary tab projects by a transverse folding line from which said aperture is spaced and being folded into an interior of the box onto an inner surface of the main panel from which said supplementary tab projects, a free end of said appendix being positionable through and retained in said aperture when the box is reclosed after being opened for the first time with consequent separation of the first lip from the respective closure panel.
