ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to blanks for forming cartons useful in packaging a plurality of articles such as cans or bottles of drink for example, and more particularly to carton blanks for packaging articles in a non-rectangular array to form, for example, a fully enclosed carton.
A known carton having an octagonally shaped base and top panel is disclosed by Chaussadas in U.S. Pat. No. 4,747,485. The carton comprises a large number of separate panels for closing the sides and ends of the carton. A separate panel is hingably connected to each of the eight edges of the top and base panels. The majority of these panels depend only substantially halfway between the associated top or bottom panel and the opposite bottom or top panel and therefore overlap an associated panel depending from the opposite top or bottom panel. A relatively complex method of folding various panels is therefore required in order to close the carton shown in U.S. Pat. No. 4,747,485.
SUMMARY OF THE INVENTION
The invention seeks to avoid or at least mitigate various problems with prior art cartons. According to one aspect of the invention there is provided a blank for forming a carton for packaging a plurality of articles comprising a series of hingably interconnected top, first side, bottom and second side panels for forming an open ended sleeve capable of receiving said articles, the top and bottom panels being similarly non-rectangularly shaped substantially to correlate with the cross-sectional shape of the array of articles in a plane parallel to said top and bottom panels, wherein a gusset comprising two hingably connected gusset panels connects the first side panel and top or bottom panel which gusset is adapted to facilitate movement of the side panel to correlate with the associated shape of a stowed array of articles during the formation of the carton.
The carton blank preferably comprises two gussets between the first side panel and the top or bottom panel which gussets cooperate with associated end portions of the first side panel to cause movement thereof during the formation of the carton. Two gussets can connect both side panels to the top panel and two gussets connect both side panels to the bottom panel.
The side panel can comprise a series of hingably connected portions, and the hingably connected portions can be separated by curvable portions which provide rounded corners in the completed carton.
One of the gusset panels can comprise a tab which protrudes therefrom to facilitate tucking of the gusset inside the carton during formation thereof. Also, one of the gusset panels can comprise means such as an edge which operably abuts an end of the carton to help retain the associated side panel in its formed position in the carton. Preferably, said protruding tab comprises said abutting edge.
Another aspect of the invention provides a blank for forming a carton for packaging a plurality of articles comprising a series of hingably interconnected main panels for forming an open ended sleeve capable of receiving said articles, two opposite main panels being similarly non-rectangularly shaped substantially to correlate with the cross-sectional shape of the array of articles in a plane parallel to said two opposite main panels, wherein a gusset comprising two hingably connected gusset panels connects a first main panel and one of the two opposite main panels which gusset is adapted to facilitate movement of the first main panel to correlate with the associated shape of a stowed array of articles during the formation of the carton.
The gusset can comprise an associated aperture which facilitates folding of the gusset, and the gusset can comprise means which close the aperture when the carton is formed. Other aspects of the invention relate to a carton and of forming a carton.
