A sift proof carton, comprising:
- a carton member having at least a first open end and comprising a first inside major flap, a second outside major flap, and a pair of opposed minor flaps, each one of said flaps including a first proximal end connected along a fold line to a body portion of said carton member for pivotal movement with respect to said first open end of said carton member for closing said first open end of said carton member when folded inwardly, a second distal end, and opposite sides, said pair of opposed minor flaps comprising a first closure surface with respect to said first open end of said carton member when folded inwardly, said first inside major flap comprising a second closure surface with respect to said first open end of said carton member by being disposed upon said pair of opposed minor flaps when folded inwardly and including first mitered portions along said opposite sides thereof, said second outside major flap comprising a third closure surface when folded inwardly with respect to said first open end of said carton member by being disposed upon both said first inside major flap and portions of said pair of opposed minor flaps, extending along said first proximal ends thereof, as a result of said portions of said pair of opposed minor flaps, extending along said first proximal ends thereof, being exposed and accessible to said second outside major flap by said mitered portions of said first inside major flap, and at least one of said pair of opposed minor flaps and said second outside major flap having embossed means formed along at least one of said exposed and accessible portions of said pair of opposed minor flaps extending along said first proximal ends of said pair of opposed minor flaps, and said opposite sides of said second outside major flap, so as to extend toward the other one of said pair of opposed minor flaps and said second outside major flap;
- and
- adhesive means, provided upon an inside surface of said second outside major flap and upon outside surfaces of said pair of opposed minor flaps, for providing seals between said pair of opposed minor flaps and said first and second inside and outside major flaps, and between said first and second inside and outside major flaps, said adhesive means comprising a first adhesive strip provided upon said outside surfaces of said pair of opposed minor flaps so as to extend across both of said minor flaps and substantially from one side of said carton body to the other side of said carton body, and along one of said opposite sides of said pair of opposed minor flaps, so as to be disposed adjacent to said fold line of said first proximal end of said first inside major flap such that edge and corner sealing is achieved between said pair of opposed minor flaps and said first inside major flap when said pair of opposed minor flaps and said first inside major flap are folded inwardly with respect to said carton body;
- a second adhesive strip provided upon said outside surfaces of said pair of opposed minor flaps so as to extend across both of said minor flaps and substantially from said one side of said carton body to said other side of said carton body, and along the other one of said opposite sides of said pair of opposed minor flaps, so as to be disposed adjacent to said fold line of said first proximal end of said second outside major flap such that said second distal end of said first inside major flap is sealed to said pair of opposed minor flaps along said other one of said opposite sides of said pair of opposed minor flaps when said pair of opposed minor flaps and said first inside major flap are folded inwardly with respect to said carton body;
- a third adhesive strip provided upon said inside surface of said second outside major flap so as to extend across said second outside major flap substantially from said one side of said carton body to said other side of said carton body, and along said second distal end of said second outside major flap, such that said second distal end of said second outside flap is sealed to said first proximal end of said first inside major flap when said first and second inside and outside major flaps are folded inwardly with respect to said carton body;
- and a pair of fourth adhesive strips provided upon said inside surface of said second outside major flap and extending respectively along said opposite sides of said second outside major flap substantially between said first proximal end of said second outside major flap and said third adhesstrip extending along said second distal end of said second outside major flap for direct engagement with said portions of said pair of minor flaps, exposed by said mitered portions of said first inside major flap and extending along said first proximal ends of said pair of opposed minor flaps, as a result of said embossed means formed upon at least one of said exposed and accessible portions of said pair of opposed minor flaps and said second outside major flap, and extending toward the other one of said pair of opposed minor flaps and said second outside major flap, upon folding of said carton flaps so as to provide a seal between said opposite sides of said second outside major flap and said first proximal ends of said pair of opposed minor flaps.
