Carton blank

A carton blank comprising:

• a unitary sheet of a relatively rigid material having an inner surface and an outer surface;
• said unitary sheet of a relatively rigid material having a left side edge, a right side edge, a top edge and a bottom edge;
• said unitary sheet of a relatively rigid material having a plurality of cut and fold lines for dividing said unitary sheet of relatively rigid material into a plurality of sidewall panel portions, a glue tab panel portion and top and bottom panel portions extending outwardly from said sidewall panel portions;
• each of said plurality of sidewall panel portions, said glue tab panel portion and said top and bottom panel portions having an inner surface;
• a sheet of a relatively flexible plastic material superposed over said inner surface of said unitary sheet of relatively rigid material;
• first securing means extending between said right side edge and said left side edge for securing a first portion of said sheet of a relatively flexible plastic material to portions of said inner surfaces of said sidewall panel portions located between said fold lines between said sidewall panel portions and said top and bottom panel portions and a first portion of said glue tab panel portion;
• a first sheet of a relatively flexible material secured to a second portion of said sheet of relatively flexible plastic material and superposed over said top panel portions and the portions of said inner surfaces of said sidewall panel portions between said first portion of said sheet of relatively flexible material and said fold lines between said sidewall panel portions and said top panel portions and a second portion of said glue tab panel portion;
• and
• a second sheet of a relatively flexible material secured to a third portion of said sheet of a relatively flexible plastic material and superposed over said bottom panel portions and the portions of said inner surfaces of said sidewall panel portions between said first portion of said sheet of relatively flexible plastic material and said fold lines between said sidewall panel portions and said bottom panel portion and a third portion of said glue tab panel portion.

A carton blank comprising:

• a first layer comprising a unitary sheet of a relatively rigid material having an inner surface and an outer surface;
• said unitary sheet of a relatively rigid material having at least a left side edge, a right side edge, a top edge and a bottom edge;
• said unitary sheet of a relatively rigid material having a plurality of cut and fold lines for dividing said unitary sheet into at least a plurality of sidewall panel portions, a glue tab panel portion and top and bottom panel portions extending from said sidewall panel portions;
• a second layer comprising a fluid impervious material having an inner surface and an outer surface;
• at least a portion of said inner surface of said first layer secured to at least a portion of said outer surface of said second layer;
• and
• at least one sheet of a relatively flexible material located between said first and second layers and being secured to said second layer and not secured to said first layer.

A carton blank comprising:

• a unitary sheet of a relatively rigid material having an inner surface and an outer surface;
• said unitary sheet of a relatively rigid material having a left side edge, a right side edge, a top edge and a bottom edge, said left and right side edges being perpendicular to said top and bottom edges;
• said unitary sheet of relatively rigid material having a plurality of cut and fold lines for dividing said unitary sheet of relatively rigid material into a plurality of sidewall panel portions, a glue tab panel portion and top and bottom panel portions extending outwardly from each of said sidewall panel portions;
• each of said plurality of sidewall panel portions, said glue tab panel portion and said top and bottom panel portions having an inner surface;
• a first sheet of relatively flexible, fluid impervious material superposed only over portions of said inner surface of said sidewall panel portions and a portion of said inner surface of said glue tab panel portion;
• first securing means extending continuously between said right side edge and said left side edge for sealing and securing a portion of said first sheet of relatively flexible material to portions of said inner surface of said sidewall panel portions adjacent to said fold lines between said sidewall panel portions and said top panel portions and to said portion of said glue tab panel portion and leaving a remaining portion unsecured;
• a second sheet of relatively flexible, fluid impervious material superposed only over other portions of said inner surface of said sidewall panel portions and another portion of said inner surface of said glue tab panel portion;
• and
• second securing means extending continuously between said right side edge and said left side edge for sealing and securing a portion of said second sheet of relatively flexible material to said inner surface of said sidewall panel portions adjacent to said fold lines between said sidewall panel portions and said bottom panel portions and to said another portion of said glue tab panel portion and leaving a remaining portion unsecured.

A carton blank comprising:

• a unitary sheet of a relatively rigid material having an inner surface and an outer surface;
• said unitary sheet of a relatively rigid material having a left side edge, a right side edge, a top edge and a bottom edge;
• said unitary sheet of a relatively rigid material having a plurality of cut and fold lines for dividing said unitary sheet of a relatively rigid material into a plurality of sidewall panel portions, a glue tab panel portion and a plurality of top and bottom panel portions extending outwardly in opposite directions from said plurality of sidewall panel portions and joined thereto by fold lines;
• said inner surface of said plurality of sidewall panel portions and said glue tab panel portion having a central body portion and opposite edge portions;
• said central body portion located between and spaced from said fold lines between said plurality of sidewall panel portions and said plurality of top wall panel portions and said fold lines between said plurality of sidewall panel portions and said plurality of bottom wall panel portions and extending into said glue tab panel portion;
• a rectangular sheet of a relatively flexible, fluid impervious material having a central body portion;
• said central body portion of said rectangular sheet of a relatively flexible material being secured to said central body portion of said inner surface of said plurality of sidewall panel portions and said glue tab panel portion;
• said rectangular sheet of a relatively flexible material having opposite edge portions;
• at least portions of one of said opposite edge portions of said rectangular sheet of a relatively flexible fluid impervious material overlying but not secured to one of said opposite edge portions of said sidewall panel portions and said glue tab panel portion;
• and
• at least portions of the other of said opposite edge portions of said rectangular sheet of a relatively flexible fluid impervious material overlying but not secured to the other of said opposite edge portions of said sidewall panel portions and said glue tab panel portion.
