  • Tamper proof folding box
    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.
