Abstract
A carton blank may be formed from a first sheet of relatively rigid material and a second sheet of relatively flexible fluid impervious material. The second sheet of relatively flexible fluid impervious material may cover some but not other portions of the first sheet of relatively rigid material in order to facilitate gluing of the other portions of the first sheet of relatively rigid material when the carton blank is assembled into a carton.
Claims30
A carton blank comprising:
- a unitary sheet of a relatively rigid material comprising an inner surface and an oppositely disposed outer surface;
- said unitary sheet of a relatively rigid material further comprising a plurality of outer edges defining an outer periphery of said unitary sheet of a relatively rigid material;
- said outer surface of said unitary sheet of a relatively rigid material having at least a first portion and a second portion;
- a unitary sheet of a relatively flexible fluid impervious material covering said first portion of said outer surface of said unitary sheet of a relatively rigid material;
- wherein said second portion of said outer surface of said unitary sheet of a relatively rigid material is not covered by said at least one unitary sheet of relatively flexible fluid impervious material;
- and
- wherein no part of said unitary sheet of a relatively flexible fluid impervious material extends beyond said outer periphery of said unitary sheet of a relatively rigid material.

A carton blank comprising:
- a first sheet of material comprising an inner surface and an oppositely disposed outer surface;
- said first sheet of material comprising a plurality of outer edges defining an outer periphery of said first sheet of material;
- said first sheet of material having a length defined between two of said outer edges of said first sheet of material;
- said first sheet of material having a width defined by another two of said outer edges of said first sheet of material, said width being perpendicular to said length;
- a second sheet of plastic material covering a portion of said outer surface of said first sheet of material;
- said second sheet of plastic material comprising a plurality of outer edges defining an outer periphery of said second sheet of plastic material;
- said second sheet of plastic material having a length defined between two of said outer edges of said second sheet of plastic material;
- said second sheet of plastic material having a width defined by another two of said edges of said second sheet of plastic material, said width of said second sheet of plastic material being perpendicular to said length of said second sheet of plastic material;
- wherein said length of said first sheet of material is equal to said length of said second sheet of plastic material;
- and
- wherein said width of said first sheet of material is greater than said width of said second sheet of plastic material.

A method of forming a carton blank, said method comprising:
- providing a sheet of first material having a first surface and an oppositely disposed second surface thereon;
- said first surface comprising a first area and a second area;
- providing a sheet of second material comprising a first portion and a second portion;
- causing said first portion of said sheet of second material to overlie said first area of said sheet of first material and said second portion of said sheet of second material to overlie said second area of said sheet of first material;
- adhering said first portion of said sheet of second material to said first area of said sheet of first material;
- thereafter, exposing said second area of said sheet of first material by removing said second portion of said sheet of second material.
