Stackable and readily separable carton blank with ease of assembly features

A knocked-down flat container blank comprising:

• a substantially flat blank of carton stock material having a shape;
• said blank having a pattern of fold lines formed thereon;
• said pattern of fold lines being configured to define with said shape, at least one captured flap and at least one capturing flap foldable and alignable in layered overlapping relationship wherein said capturing flap is configured for capturing at least one thickness of carton stock of said captured flap in a sandwich-like relationship between two thicknesses of carton stock of said capturing flap when said blank is fully assembled in the form of a three-dimensional structure have a container shape;
• an elongated generally rectangular portion of the surface area of said capturing flap, proximate a distal edge of said capturing flap, having a separable strip of non-stick material adhered thereto, said strip having a finite thickness;
• said separable strip being adhered to said portion of the said surface area on said capturing flap portion by an adhesive contacting both of said capturing flap portion of said blank of carton stock material and said separable strip in an elongated generally rectangular area coextensive with said strip, and characterized by a greater adherence force between said adhesive and the carton stock material of said blank than the adherence force between said adhesive and the surface of said strip of non-stick material, and wherein said adhesive and said strip are applied only to the capturing flap of the capturing and captured flaps.
