BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to handle arrangements for paperboard cartons, such as fully enclosed cartons, partially enclosed cartons, sleeve type cartons. Such cartons may be used for holding a number of cans, bottles or other articles.
SUMMARY OF THE INVENTION
According to the present invention there is provided a paperboard carton having a top panel, a base panel, two oppositely disposed end panels hingedly connected to said top panel and a separate strap handle extending between the two end panels and being adhesively secured thereto, cuts being provided in each end panel on both sides of the adhesively secured portion of the strap handle, which cuts also extend across the hinges with the top panel and into the top panel.
In preferred arrangements the top panel provides a substantially continuous and uninterrupted surface except for the cuts.
Preferably the pair of cuts in each end panel flare outwardly and downwardly from the hinge with the top panel. Also, the lowermost end of each cut is provided with stress relieving means. In one arrangement the stress relieving means comprises an arcuate end portion of the cut which end portion extends outwardly and upwardly.
A further preferred feature is that the parts of each pair of associated cuts in the top panel are substantially parallel. Also further stress relieving means is also provided at the ends of the cuts in the top panel.
In one such arrangement said further stress relieving means is in the form of the end of the cuts curving outwardly.
Another feature is that between each pair of cuts in the top panel is a transverse fold which is parallel to and is spaced from the hinge between the associated end panel and the top panel.
In preferred arrangements the handle is in the form of a parallel sided strip of plastic or paperboard and the carton is in the form of a fully enclosed carton incorporating side panels. A further feature is that the adhesive for the handle extends up to the junction of the end panels and the top panel and the cuts include frangible connections which break in use of the carton so that the cuts extend their full length when the handle is used.
Embodiments of the present invention will now be described in more detail. The description makes reference to the accompanying drawings:
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a paperboard blank for forming a carton,
FIG. 2 shows the FIG. 1 blank with a handle member attached,
FIG. 3 is a perspective view of the FIG. 2 arrangement assembled, and
FIG. 4 is an enlarged perspective view of part of the FIG. 3 assembly from another angle with the assembly being lifted by the handle.
DETAIL DESCRIPTION
In the figures there is shown a blank 10 for forming a carton 11 for receiving therein an article or a number of articles such as cans or bottles. The blank 10 has a top panel 12, oppositely disposed end panels 13 hingedly connected to the top panel 12 at folds 14 and oppositely disposed side panels 15 hingedly connected to the top panel 12 at folds 17. A base panel 18 and an overlapping adhesive panel 19 are also provided as well as base closure flaps 20 and side closure flaps 21. When folded and secured together the blank produces the generally rectangular cuboid carton 11, although the upper parts 22 of the end panels 13 are angled slightly inwards in the arrangement shown. In other arrangements the upper parts of the side panels 15 could be angled inwards.
Spanning each fold 14 between the top panel and its associated end panel 13 is a pair of cuts 23. The pair of cuts 23 are centrally disposed along the fold 14 and extend parallel to each other in the top panel and flare outwardly and downwardly from the fold 14 in the end panel 13.
Apart from the cuts 23, the top panel 12 provides a continuous, uninterrupted surface which is particularly suitable for printing and which has no joins.
The lower ends of the cuts 23 in each end panel 13 are provided with stress relieving means 24 which in this embodiment comprise arcuate continuations of the cuts 23 exte
