Abstract
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.

Claim 1
Independent Claim
345 words
A carton comprising a plurality of panels arranged to form walls of said carton, said walls including at least first and second pairs of walls with the walls of each pair being remotely disposed, said first pair of walls including first and second walls, said first wall of said first pair being a double wall and including inner and outer panels, said second pair of walls including first and second walls each of a double wall construction and being disposed next adjacent said first wall of said first pair of walls, said first wall of said second pair of walls including a first terminal panel and a first intermediate panel with said terminal panel being bonded to the interior of said intermediate panel, said second wall of said second pair of walls including a second terminal panel and a second intermediate panel, said second terminal panel being an exterior panel having an interior surface thereof bonded to said second intermediate panel, said second terminal panel having free edge disposed remote from said first wall of said first pair of walls and being generally of the same width as said second intermediate panel, said carton has at least one closed end formed by a plurality of closure members; said closure members including an outer closure flap hingedly carried by said second terminal panel, an inner closure flap hingedly carried by said second intermediate panel, said inner closure flap and said inner closure flaps being bonded together and folded to form part of said closed end and to prevent separation of said second terminal panel from said second intermediate panel, an outer closure panel hingedly carried by said second wall of said first pair of walls and overlying said closure flaps, said closure panel terminating in a tuck flap positioned between said inner and outer panels of said first wall of said first pair of walls, and securing means permanently bonding an inner surface of said tuck flap to an outer surface of said inner panel at a location which is completely inaccessible in the sealed carton.
Claim 2
Dependent Claim
345 words
A carton comprising a plurality of panels arranged to form walls of said carton, said walls including at least first and second pairs of walls with the walls of each pair being remotely disposed, said first pair of walls including first and second walls, said first wall of said first pair being a double wall and including inner and outer panels, said second pair of walls including first and second walls each of a double wall construction and being disposed next adjacent said first wall of said first pair of walls, said first wall of said second pair of walls including a first terminal panel and a first intermediate panel with said terminal panel being bonded to the interior of said intermediate panel, said second wall of said second pair of walls including a second terminal panel and a second intermediate panel, said second terminal panel being an exterior panel having an interior surface thereof bonded to said second intermediate panel, said second terminal panel having free edge disposed remote from said first wall of said first pair of walls and being generally of the same width as said second intermediate panel, said carton has at least one closed end formed by a plurality of closure members; said closure members including an outer closure flap hingedly carried by said second terminal panel, an inner closure flap hingedly carried by said second intermediate panel, said inner closure flap and said inner closure flaps being bonded together and folded to form part of said closed end and to prevent separation of said second terminal panel from said second intermediate panel, an outer closure panel hingedly carried by said second wall of said first pair of walls and overlying said closure flaps, said closure panel terminating in a tuck flap positioned between said inner and outer panels of said first wall of said first pair of walls, and securing means permanently bonding an inner surface of said tuck flap to an outer surface of said inner panel at a location which is completely inaccessible in the sealed carton.
