In some embodiments, the support panel 110 may be sandwiched between top panels 66, 76 to form an integral multiply structure.

  • a significant reduction in stress which is transmitted to the handle occurs due to the collection of the score lines with the weakened severance lines from each comer of the top wall.
  • the comer structure of known cartons is fully enclosed and the fold lines defining top or bottom, and side and end wall panels intersect to define the comers.
  • This approach is undesirable, because it can cause a concentration in stresses at the comers when the carton is lifted.
  • the carton of the present invention incorporates bevelled comers between the side and end walls and preferably include bevelled upper and lower carton walls which results in comer structures with apertures 120, shown in Figure 5.
  • the aperture 120 leads to a reduction in stress, but it can be less rigid.
  • the portion 122 of top and side wall panels is formed by the extension of severance lines 104 extending across the upper bevelled panel and into the side walls.
  • the combination of locking and gluing the base in which the bottom panels are first locked then the end flaps are glued onto the lapped panels provides a more secure base structure to support articles contained in the carrier than other known base structures.
  • hinged connection should not be construed as necessarily referring to a single fold line only: indeed it is envisaged that the hinged connection can be formed from one or more of the following: a score line, frangible connection or a fold line without departing from the scope of invention.
  • the present invention and its preferred embodiments relate to a package, carton or article carrier which is shaped to provide a satisfactory rigidity to hold items such as cans with a degree of flexibility.
  • the shape of the blank minimizes the amount of paperboard required for the carton.
  • the carton can be constructed from a flap collapsed condition to a position of use by hand or automatic machinery. It is anticipated that the invention can be modified, without departing from the scope of invention, for example the top wall panel stmcture can be applied to wraparound or end loaded cartons of a known type.
