Definitions

  • the present invention relates to cartons, to blanks suitable for the construction of such cartons and to methods of manufacturing cartons.
  • Radiused cornered paperboard containers are commonly used in packaging a variety of articles such as bottles, cookies, confectionery, granular foodstuffs, potato chips and other such articles/items.
  • the majority of these containers are manufactured in remote locations and shipped in a set up form to the point of product packing.
  • expensive dedicated machinery is set up at the side of the packing operation to manufacture the containers and thus avoid the shipping costs and associated logistical problems.
  • GB 2451281 discloses a round or curved carton. This carton however has a complicated base structure which is difficult and costly to glue into its desired flat or knock down state.
  • An aim of the present invention is to provide a radiused cornered container with a strong and substantially flat base or lid which is less complicated in its construction and method of manufacture.
  • GB 2451281 has a base which sits recessed from the bottom of the carton. It is advantageous to have the base structure resting on the ground when erected. The load of the product is transferred in this case directly to the surface below rather than through the base construction itself.
  • a method of construction of a carton from a blank comprising a side wall having free ends, the side wall comprising a first panel connected to a second panel, a hinged base panel connected to the first panel and an inner base panel hingedly connected to the second panel, the method comprising the steps of folding the hinged base panel above the first panel, folding the inner base panel over the second panel, folding the hinged base panel about the central crease line, affixing part of the of the reverse of the hinged base panel to a corresponding part of the face of the inner base panel comprising folding the first and second panels relatively towards each other, fixing the free ends of the side wall and moving the hinged locking base panel and the inner base panel to form a base of the carton, whereby the hinged base panel and inner base panel are configured to form a base at the bottom of the carton.
  • side locking base panels are pushed through corresponding apertures in the hinged base panel.
  • the ends of the side locking base panels are provided with one way entry barbed ends to prevent them from disassembling once constructed.
  • the carton is provided with a plurality of crease or weakening lines located in the areas where the radius corners occur, designed to allow the carton to curve uniformly at the corners.
  • the carton is erected over a former or mandrill of substantially the same shape as the finished carton profile.
  • the free end of the first panel is affixed to the free end of the second panel, but if there are more than two panels, the relevant free ends are fixed together.
  • the partly assembled carton is placed over a mandrill or forming tool and pressure applied to the two opposite creases to open up the carton and form the base.
  • the side locking panels are folded over and secured to the hinged base panel.
  • a carton comprising a side wall comprising a first panel connected to a second panel, the first and second panels having free ends, a hinged base panel hingedly connected to the first panel and an inner base panel hingedly connected to the second panel, the hinged base locking panel being folded along a hinge line thereof and affixed to the inner base panel, the free ends of the sidewall being fixed to each other, whereby the hinged base panel and inner base panel are configured to form a base at the bottom of the carton.
  • the hinged base panel is replaced by an inner base panel with no hinge.
  • the carton is glued at its free ends only and placed over a mandrill or former.
  • the inner base flap is folded over first and is provided with cutouts to receive one or more side locking panels.
  • an outer base flap is folded over and glued to at least the inner base panel but additionally can be glued also to one or more side locking panels.
  • the hinged base panel, the inner panel and /or the outer base panel are substantially square or rectangular in cross sectional shape with radiused corners.
  • the hinged base panel and the inner base panel can be a variety of radiused cornered shapes such as square, rectangular, triangular etc in cross- section.
  • the inner base panel comprises at least one flap extending therefrom, configured to be folded to lie against the inside of the first panel or the second panel in the made-up carton.
  • a flap extends from an end of the inner base panel and a second flap extends from an opposing end of the inner base panel, whereby the first flap is configured to be folded to lie against the inside of the first panel in the made up carton and the second flap is configured to be folded to lie against the inside of the second panel in the made up carton.
  • a first shaped flap extends from the edge of the first panel opposite the edge from which extends the hinged base panel and a second shaped flap extends from the corresponding edge of the second panel, whereby the first shaped flap and the second shaped flap provide a plurality of recessed arms.
