ABSTRACT:
This relates to cartons or packages which are sealed in a manner wherein they cannot be opened no matter how careful one is without giving an indication of tampering. In one form of the invention, an outermost closure panel is provided with a tuck flap which extends down between inner and outer panels of a double wall carton body wall and the inner surface of the tuck flap is bonded to the exterior surface of an inner panel to provide an inaccessible bond. Panels of cartons which are bonded together and have an accessible seam may be provided with an arrangement of weakening lines so that if one attempts to destroy the bond using a knife or razor blade, the exposed outer panel will give evidence of rupturing and thus indicate tampering even though the two panels are later resealed. If desired, the inner of the two panels may also have an arrangement of weakening lines which match that of the exterior panel and the weakening lines may be arranged in rows extending transversely of the panels so that the bonded together panels may be readily torn to effect an opening of the package.
