Claims13
A wrap-around article carrier for carrying articles comprising;
- (a) a top panel, opposite side panels and a bottom panel;
- (b) the bottom panel having inner and outer panel flaps, a portion of the outer panel flap overlapping a portion of the inner panel flap;
- (c) the inner panel flap having at least one lock ledge formed by an opening cut in the inner panel flap;
- (d) the outer panel flap having at least one primary lock for each lock ledge, formed by a slit cut in the outer panel flap;
- (e) the outer panel flap having at least one secondary male lock formed as an extension of the flap;
- (f) the inner panel having at least one secondary female opening for each secondary male lock, said secondary female opening formed by a slit and fold line which forms a flap in the female opening, said flap leaning against the secondary male lock when it has been extended through the female opening to assist in holding the secondary male lock in a vertical position with respect to the outer flap so the lock does not become accidentally disengaged, the slit forming the flap on the secondary female opening is substantially parallel to and closer to the end of the inner flap than the fold line by which the flap in the female opening is connected to the bottom panel flap.
