Appeal No. 2000-1789 Page 5
Application No. 08/699,572
D) 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;
E) 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.
16. A plurality of knocked-down flat carton blanks comprising:
A) a plurality of substantially flat, unfolded blanks of carton stock material
each having the same configuration.
B) each blank having a pattern of fold lines for folding said blank into a
three-dimensional structure having a container shape;
C) each blank having at least one flap positionably adjacent to another
portion of the blank such that secured attachment of said flap to said other
portion of the blank retains the blank in said three-dimensional structure having a
container shape;
D) an elongated generally rectangular area of adhesive applied to the
carton blank along a peripheral edge thereof for securing said flap to said other
portion of the blank;
E) an elongated generally rectangular strip of non-stick material
coextensive with and positioned over the adhesive and separable therefrom to
expose the adhesive for securing the flap to said other portion of the blank, said
strip of non-stick material forming a surface discontinuity extending to an edge of
said blank creating an air passage for precluding formation of an air vacuum
suction lock between abutting blanks; and
F) said plurality of substantially flat, unfolded blanks arranged in an
aligned stack with air passages formed by the strip of non-stick material
extending to the edge of the stack to permit easy separation of abutting stacked
blanks.
