  • Patent number: 6109517
    Abstract: The present invention refers to a constructive arrangement applied to an opening device for packages of the carton type, containing a dry product, either powdered or granulated, such as powdered soap or the like. The constructive arrangement includes a transversely semiarticulated tongue which has perforated lines. The tongue is defined by a semicircular area disposed in one of the side faces of the package and by a rectangular area disposed in the upper face thereof. An articulated rectangular flap is positioned on the portion which is disposed in the upper face and also has perforated lines. To open the package, these perforated lines are broken and the semiarticulated tongue and the rectangular flap are moved so as to be juxtaposed in the vertical position in the upper face of the package. In operation, the semiarticulated tongue is folded so that its semicircular and rectangular parts will be joined together in the vertical position.

  • Patent number: 5190155
    Abstract: A folding box has a reclosable end flap opening on a side wall panel end which defines a seal identifying segment portion. The reclosable end flap covers the reclosable opening and has a bent over flap extension adjacent to the seal identifying segment. The box permits hand separation of the segment to break the seal of the box while allowing the reclosable flap to act as a reclosable portion after the seal is broken so that there is a visible indication that the seal is no longer intact.
