ABSTRACT:
FIELD OF THE INVENTION
This invention relates to paperboard cartons with end wall handles.
SUMMARY OF THE INVENTION
According to the present invention, there is provided a paperboard carton having a base panel, a top panel, two oppositely disposed side panels and two oppositely disposed end walls, each end wall comprising a portion of multiple thickness in which portion there is a handle opening.
Preferably each end wall comprises an upper portion which is hingedly connected to the top panel and which comprises said multiple thickness portion, and a lower portion which is hingedly connected to the base panel, the upper portion being adhesively secured to the lower portion to fully enclose the ends of the carton. In a preferred arrangement the upper portion of each end wall comprises a first panel hingedly connected to the top panel, a second panel hingedly connected to the first panel and adhesively secured with respect to the first panel. Normally, the hinge connection between the first and second panels of each end wall is substantially parallel to the hinge connection between the first panel and the top panel.
In further embodiments each end wall further comprises a third panel. Conveniently said third panel is hingedly connected to said second panel, the hinge connection being substantially perpendicular to the hinge connection between the first and second panels. In one arrangement said third panel is hingedly secured between the first and second panels.
It is a preferred feature that a pair of side end panels is hingedly connected to respective side panels at each end of the carton, said side end panels being folded inwardly of the upper and lower end wall portions.
Preferably the top, one side panel, base and the other side panel are hingedly connected in series by means of substantially parallel fold lines and also an adhesive flap is hingedly connected to the top panel opposite said one side panel for attachment to the other side panel.
With preferred embodiments lines of weakening are provided in the top panel to facilitate access to the contents of the carton and conveniently said lines of weakening extend into the side panels.
