Abstract

A fully enclosed paperboard carton having a top, a base, a pair of oppositely disposed sides and a pair of oppositely disposed end panels. Each end panel being substantially planar and perpendicular to the base and top. Each side having a lower portion that is substantially planar and perpendicular to the base and an upper portion that is substantially planar and tapers inwardly towards its edge connection with the top.

Claims

1. A fully enclosed paperboard carton comprising:

a top, a base, a pair of oppositely disposed sides and a pair of oppositely disposed end panel;

each said end panel being substantially planar and perpendicular to the base and the top;

each side having a lower portion that is substantially planar and perpendicular to the base; and

an upper portion that is substantially planar and tapers inwardly towards an edge connection with the top.

2. The carton as claimed in claim 1 wherein each end panel comprises top, base and side end panels each hingedly connected and adhesively secured to the respective top, base and sides.

3. The carton as claimed in claim 2 wherein each base end panel is foldably connected at each side to a gusset panel which in turn is hingedly connected to its adjacent side end panel.

4. The carton as claimed in claim 3 wherein the fold connection of the gusset panel with the base end panel is perpendicular to the fold between the base and the base end panel and the fold connection of the gusset panel with the side end panel is 45°

relative to the fold connection to the base end panel.

5. The carton as claimed in claim 4 wherein a further fold between said 45°

fold connection and the upright fold with a cut links the upper end of the further fold to the edge of the side end panel.

6. The carton as claimed in claim 2 wherein each top end panel has a primary push through flap to define a handle hole.

7. The carton as claimed in claim 6 wherein at each end of the carton, each of the two side end flaps are positioned behind the top end panel and have a secondary push through flap behind the primary push through flap, all push through flaps being rotatable inwardly through 180°

when moved into a carrying position.

8. The carton as claimed in claim 6 wherein the primary push through flap at each end remains hingedly connected to the top end panel along a substantially straight primary fold line.

9. The carton as claimed in claim 8 wherein the primary fold line comprises a pair of folds, spaced vertically a small distance to define a support panel therebetween.

10. The carton as claimed in claim 9 wherein the secondary push through flaps at each end remain hingedly connected to the side end panels along substantially straight secondary fold lines adjacent the primary fold line.

11. The carton as claimed in claim 2 wherein at each end of each side, a corner formation each defines a pair of creases, one crease extending from the apex between the top, side and end panel arrangement to a horizontal crease joining the upper and lower side portions and an other crease extending from the apex between the base, side and end panels to the join between the upper and lower side portions.

12. The carton as claimed in claim 1 wherein lines of weakening are provided to facilitate access to the carton.
