Carton, carton blank and associated methodology
View Patent ↗A carton blank may be formed having at least one score line therein. A second layer of material may overlay at least a portion of the first layer, including the score line, thus defining an overlaid score area. The overlaid score area may include at least a portion in which the second layer is not adhered to the first layer.
1. A carton blank comprising:
a first layer of material comprising a plurality of score lines formed therein, wherein the plurality of score lines define a plurality of central panels of the first layer of material; and
a second layer of material overlaying at least a portion of an inner surface of the first layer of material, wherein
portions of the second layer of material overlaying the plurality of score lines in the first layer of material comprise overlaid score areas,
each overlaid score area comprises a non-adhered portion, a first adhered portion at a first end of the non-adhered portion, and a second adhered portion at a second end of the non-adhered portion,
the second layer of material is not adhered to the first layer of material at the non-adhered portions,
the second layer of material is adhered to the first layer of material and is in direct contact with the score lines at the adhered portions, and
the second layer of material is adhered to the central panels at locations between the overlaid score areas.
2. The carton blank of claim 1 , wherein the carton blank is folded about at least two of the score lines by approximately one hundred and eighty degrees.
3. The carton blank of claim 2 , wherein the plurality of central panels includes at least one glue panel adhered to one of the remaining central panels.
4. The carton blank of claim 2 , wherein the plurality of score lines are pressed into the first layer from an outer surface of the first layer of material that is opposite to the inner surface of the first layer of material.
5. The carton blank of claim 2 , wherein:
the first layer of material has a first thickness; and
the second layer of material has a second thickness less than the first thickness.
6. The carton blank of claim 2 , further comprising:
a plurality of top flap panels spaced from the non-adhered portions; and
a plurality of bottom flap panels spaced from the non-adhered portions.
7. A carton comprising:
a first layer of material comprising a plurality of score lines formed therein, wherein the plurality of score lines define a plurality of central panels of the first layer of material;
a second layer of material overlaying at least a portion of an inner surface of the first layer of material, the second layer of material having a sealed portion and an open top end;
a plurality of top flap panels; and
a plurality of bottom flap panels, wherein
portions of the second layer of material overlaying the plurality of score lines in the first layer of material comprise overlaid score areas,
each overlaid score area comprises a non-adhered portion, a first adhered portion at a first end of the non-adhered portion, and a second adhered portion at a second end of the non-adhered portion,
the second layer of material is not adhered to the first layer of material at the non-adhered portions,
the second layer of material is adhered to the first layer of material and is in direct contact with the score lines at the adhered portions,
the second layer of material is adhered to the central panels at locations between the overlaid score areas,
the plurality of bottom flap panels are spaced from the non-adhered portions, and
the plurality of bottom flap panels are spaced from the non-adhered portions.
8. The carton of claim 7 , wherein the plurality of central panels includes at least one glue panel adhered to one of the remaining central panels.
9. The carton of claim 7 , wherein the plurality of score lines are pressed into the first layer from an outer surface of the first layer of material that is opposite to the inner surface of the first layer of material.
10. The carton of claim 7 , wherein:
the first layer of material has a first thickness; and
the second layer of material has a second thickness less than the first thickness.
