Method and adhesive pattern for a reverse fold sift proof carton

Claim 1

A method of folding and sealing the major and minor side and end flaps of a carton so as to provide a sift proof container, comprising the steps of: providing a carton having a pair of opposite sides, a pair of opposite ends, and at least an open top including a first inside major flap, a second outside major flap, and a pair of opposed minor flaps, wherein each one of said flaps is pivotably connected to a respective one of said opposite sides and said opposite ends of said carton so as to be foldable with respect to said open top so as to close off said open top; positioning said minor flaps, said first inside major flap, and said second outside major flap in a predetermined open position with respect to said top of said carton; folding said first inside major flap inwardly so as to cover said open top of said carton; applying multiple beads of adhesive to peripheral areas of the inside surface of said second outside major flap, to peripheral areas of the outside surface of said first inside major flap, and to peripheral areas of the inside surfaces of both of said minor flaps such that said adhesive applied to said outside surface of said first inside major flap and to said inside surfaces of said minor flaps extends across gaps defined between said folded first inside major flap and said open minor flaps, and said adhesive applied to said peripheral areas of said inside surface of said second outside major flap and to said peripheral areas of said outside surface of said first inside major flap cooperate together so as to be disposed about the entire periphery of said top of said carton when said minor flaps and said second outside major flap are folded inwardly over said folded first inside major flap so as to provide said carton with a peripheral seal extending about the entire periphery of the closed top of said carton; folding said minor flaps inwardly into engagement with said first inside major flap; and folding said second outside major flap inwardly into engagement with said first inside major flap and both of said minor flaps such that said adhesive and said peripheral areas where said adhesive has been applied provide sealing contact between said flaps about the entire periphery of said closed top of said carton so that said carton is rendered sift proof.

Claim 2
