Definitions

  • the present invention relates to apparatus and methods for forming containers and to containers formed from such apparatus and methods.
  • Containers such as cardboard containers are well known in the art. Some cardboard containers are formed manually from container blanks which are often made available in a flat configuration, where fold lines are provided for a person to fold the blank into a container.
  • One example of such containers is the "TrayBonTM" cardboard container made by TrayBon Bakery Pkg. Sys., a Division of AMCOR Ltd. While the TrayBonTM container is available in several size configurations, all configurations have a rectangular base and four sidewalls extending upwardly from the perimeter of the base.
  • FIG. 1 An example of one configuration of a TrayBonTM container blank 10 for forming into a container is illustrated in Figure 1, showing a base 11, a first pair of opposed wall portions 12a,b and a second pair of opposed wall portions 14a,b, and interlocking devices, comprising male tabs 16a,b and corresponding slots 18a,b, the male tabs 16a,b extending from ends 20a,b of the first pair of wall portions 12a,b.
  • An open container can be formed from the blank 10 by turning wall portions 12a,b and 14a,b on their respective fold lines 22a,b and 23a,b such that the male tabs 16a,b fold behind wall portions 14a,b, respectively.
  • Wall portions 14a,b are then respectively folded on fold lines 24a,b outwardly upon themselves and over the folded male tabs 16a,b.
  • an extension 26a,b of each of male tabs 16a,b is forced through corresponding slots 18a,b on the wall portions 14a,b to interlock the tabs 16a,b with the wall portions.
  • a distal part 28a,b of wall portions 14a,b must be extended over their respective male tab extensions 24a,b. In practice, this can lead to undesired buckling of the male tabs 16a,b, resulting in a less effective or ineffective interlock between the tabs 16a,b and the slots 18a,b.
  • an apparatus for forming a container from a container blank having a base, first and second wall portions and a catch device extending from the first wall portion for connecting to a corresponding portion on the second wall portion such that the wall portions form first and second sidewalls of the container

  • a support to support the catch device when the second wall is folded upon itself and over the catch device, undesired buckling of the catch device is prevented.
  • the support can be movable with respect to the fold device and/or the container. Further, the support can be movable, when the blank is in the preassembled condition, between a first position, away from the blank, and a second position against the catch device supporting the catch device against the second wall portion.
  • the support can be configured to turn the catch device from the plane of the first wall portion to a position against the second wall portion when moving from the first position to the second position. Also, the support can be configured to be removed from the container, once the second wall portion has been folded upon itself, to a third position being different to the first position. Alternatively, the third position is the same as the first position.
  • the corresponding portion of the container may comprise an opening in the wall portion, such that an end of the catch device may pass into the opening when the second wall portion is folded.
  • the support can be configured such that, when in its second position, an end thereof corresponding to the catch device end passes in to the opening of the corresponding portion when the second wall portion is folded.
  • the support may be configured such that the support end is removed from the opening when moved from the second position into the third position.
  • the apparatus may further comprise a folding assembly to fold the blank into the preassembled condition, where the first and second wall portions are turned out of the plane of the base.
  • the folding assembly may comprise a folding chamber and folding ram.
  • the fold device may be disposed on the folding ram.

  • the container 148 may be ejected from the chamber 138 using rotatable shunts 152a,b which are rotatably attached to respective support blade arms 149a,b.
  • the shunts 152a,b move the formed container 148 from the chamber 138.

Abstract

L'invention concerne un procédé et un appareil permettant de former un contenant à partir d'une découpe de contenant. L'appareil et le procédé servent à former des contenants à partir de découpes ayant un fond, une première partie de paroi et une deuxième partie de paroi, et un dispositif de fermeture s'étendant en provenance de la première partie de paroi à des fins de connexion au niveau d'une partie correspondante sur la deuxième partie de paroi de telle manière que les parties de paroi forment la première paroi latérale et la deuxième paroi latérale du contenant. L'appareil comporte le support configuré, quand la découpe est dans un état préassemblé dans lequel la première partie de paroi et la deuxième partie de paroi sont tournées vers l'extérieur au niveau du plan du fond, pour supporter le dispositif de fermeture contre la deuxième partie de paroi. De plus, un dispositif de pliage est configuré pour plier une partie de la deuxième partie de paroi sur elle-même et sur le dispositif de fermeture pour permettre au dispositif de fermeture de coopérer avec la partie correspondante de la deuxième partie de paroi. Le support empêche la partie dispositif de fermeture de se déformer quand la première partie est pliée dessus.
