Carton and stress relieving score pattern for handle

摘要

A carton blank is assembled into a carton for beverage containers, the blank having a number of panels including a top panel, a bottom panel and a pair of side panels each joined by a fold line to an adjacent one of the panels. A number of end flaps are each joined by an end flap fold line to one of the panels and the end flaps are adapted to be folded upon selected other end flaps to form composite end panels of the carton. A carrying handle is formed in a selected one of the panels and adapted to be grasped by a user to carry the erected carton filled with the beverage containers. A pattern of stress-relieving score lines are formed in the carton blank to produce a desired buckling of the carton when erected, filled and lifted to avoid tearing of the carton material.

主权项

1. A carton blank to be assembled into a carton for beverage containers, the carton blank comprising:
a plurality of panels including a top panel, a bottom panel and a pair of side panels each joined by one of a plurality of panel fold lines to an adjacent one of the panels; a plurality of end flaps each joined by one of a plurality of end flap fold lines to one of the panels, the end flaps being adapted to be folded upon other end flaps to form composite end panels of the carton; a carrying handle formed in a selected one of the panels and adapted to be grasped by a user to carry the erected carton when filled with the beverage containers; a pattern of stress-relieving score lines in the blank positioned relative to the carrying handle so as to distribute lifting stresses exerted on the carton to avoid tearing the panels; wherein the pattern of stress-relieving score lines is located in both the selected one of the panels and an adjacent panel; a primary reinforcing panel joined to one of the panels such that the primary reinforcing panel may be folded into face to face juxtaposition with the selected one of the panels; and a secondary reinforcing panel joined to one of the panels via a secondary reinforcing panel fold line about which the secondary reinforcing panel may be folded into face to face juxtaposition with at least one of the primary reinforcing panel and the selected one of the panels; wherein when the primary and secondary reinforcing panels are folded into position at least portions of the selected one of the panels surrounding the handle have a triple layer of thickness.
