Definitions

  • the present invention relates to a collapsible container that is suitable for stacking.
  • Stacking containers are widely used in the retail industry for transporting produce such as fresh fruit and vegetables from the growers to the shops, and for displaying those goods for sale.
  • the containers protect the goods during transportation and storage and may be stacked for efficient handling and storage. After the goods have been sold, the containers are washed and returned for re-filling.
  • the first type of container is nestable and has inclined or stepped walls and a mouth that is larger than the base. This allows an empty container to be nested with similar containers.
  • Nestable containers normally have retractable stacking bars (or "bale arms") that can be positioned over the mouth of the container, allowing it to be stacked with other similar containers in an unnested configuration (also sometimes called a "column stacked" configuration) with virtually no intrusion into the enclosed volume of the container.
  • the stacking bars can be located in a third position to allow stacking in a partially nested condition.
  • the stacking bars also allow slide stacking, in which a container is stacked by placing it on a lower container in an offset position and then sliding it to its final stacking position. This improves handling of the containers.
  • An example of a nestable container is described in EP 0553540 .
  • the second main type of container is collapsible and generally has a rectangular base and four walls that are attached to the edges of the base by hinges.
  • the walls can be folded flat onto the base for transportation and storage when empty.
  • the walls are vertical and the mouth of the container is the same size as the base.
  • collapsible container described in EP 0911268 is not compatible with nestable containers. In other words, nestable and collapsible containers cannot be stacked together, because the base of the nestable container will fit within the collapsible container.
  • An answer to this problem is supplied by the container described in WO 01 /44060 . That document describes a collapsible container that has pivoting stacking bars attached to the end walls. The stacking bars can be positioned over the mouth of the container to allow stacking with nestable containers, as well as with similar collapsible containers. The stacking bars also serve as a secondary locking device to retain the walls in the upright configuration, and they allow slide stacking.
  • a collapsible container that may be configured in a collapsed condition or an erected condition, including a base and a plurality of walls that are pivotally attached to the base and arranged to lie substantially parallel with the base when collapsed and to stand substantially perpendicular to the base when erected, said walls having free edges that define a mouth when the container is an erected condition, and at least one stacking element carried by one of said walls and located towards a free edge of said carrying wall for supporting the base of a second container stacked on the collapsible container, wherein the plurality of walls include two shorter walls that lie adjacent the base when collapsed and two longer walls that overlie the shorter walls when collapsed.
  • the stacking element is pivotally attached to the carrying wall and is constructed and arranged to be configured in a deployed condition for stacking in which it extends at least partially into the mouth of the container, or a retracted condition in which it is withdrawn from the mouth of the container.
  • the stacking element is constructed and arranged to deploy automatically when the container is erected, and to retract when the container is collapsed. Because the stacking elements are deployed and retracted automatically, the need for a laborious manual operation is avoided. The risk of damage to the goods through failure to deploy the stacking bars is also avoided.
  • Resilient biassing means is provided to cause deployment: this may be part of the stacking element, part of a wall or a separate component.
  • the container described above provides a number of important advantages over the prior art.
  • the stacking element or elements
  • the stacking element(s) are however able to support a second container stacked on top of the folding container, the base of the second container being smaller than the mouth of the collapsible container.
  • the container can therefore be stacked either with similar collapsible containers or with nesting containers. Further, when the container is in a collapsed condition it occupies less than 25% of the volume occupied when it is in an erected condition, thereby providing greater economies in shipping costs.
  • the length of the shorter walls is preferably less than the separation of the erected longer walls, so that the shorter walls can pivot between the erected longer walls.
  • the collapsible container includes a pair of stacking elements carried by an opposed pair of walls.
  • references to a stacking element apply equally to pairs of stacking elements.
  • the stacking element is pivotally attached to an inner face of the carrying wall.
  • the stacking element is constructed and arranged to retract into a recess in the wall.
  • the resulting container is suitable for automatic filling owing to the small intrusion of the stacking elements into the mouth of the container and the fact that the stacking elements can be easily retracted into the recesses if necessary.
  • the stacking element may be pivotally attached to an upper edge of the carrying wall.
  • the stacking element may be constructed and arranged to retract to an upright position in which it extends upwards from the upper edge of the carrying wall.
  • the resilient biassing means is constructed and arranged to bias the stacking element when the container is in an erected condition, and to apply no bias when the container is collapsed.
  • the resilient biassing means is constructed and arranged to engage a support element (for example a flange) on a wall adjacent said carrying wall, when the container is in an erected condition, thereby urging the stacking element towards the deployed condition.
  • a support element for example a flange
  • the resilient biassing means disengages the support element, to relieve any stresses in the biassing means.
  • the resilient biassing means is provided on a wall adjacent the carrying wall.
  • the stacking element includes end portions that are constructed and arranged to engage and support adjacent walls of the erected container when deployed.
  • the stacking element extends along substantially the entire length of the carrying wall.
  • the stacking element may be pivotally attached to the shorter wall (the end wall), allowing slide stacking from the sides of the container.
  • the stacking element may be pivotally attached to the longer wall (the side wall).
  • the stacking element is arranged to support the shorter walls when deployed, thereby preventing unintended collapse of the walls.
  • Stacking elements may be located towards the ends of the longer walls.
  • the stacking element is pivotally attached to the shorter wall.
  • the stacking element may include locking elements that are constructed and arranged to engage the longer walls when deployed, to prevent unintended collapse of the walls.
  • the first container 100 shown in Figures 1-6 comprises a substantially rectangular base 102, two longer side walls 104 and two shorter end walls 106.
  • the side walls and the end walls are attached to the base 102 by means of hinges 108, which allow the walls to be folded flat onto the base 102 for storage or transportation in a collapsed condition, as shown in Figure 2 .
  • the end walls 106 are folded first and that in the collapsed condition they lie adjacent to the base 102.
  • the length of the end walls 106 is less than the separation of the erected side walls 104, so that the end walls can pivot between the side walls.
  • the side walls 104 are collapsed after the end walls 106 and in the collapsed condition overlie the end walls 106.
  • Recesses 109 are provided where necessary in the side walls to allow them to lie flat against the end walls.
  • Complementary locking formations 110 in the form of resilient detents are provided on the end walls and the side walls, to lock the walls together when the container is in the erected condition as shown in Figure 1 .
  • the locking formations 110 are conventional and will not be described in detail.
  • the upper edges 112 of the side walls 104 and the end walls 106 are designed to receive the edges of the base 102 of a similar container when the containers are stacked in an erected, column stacked condition.
  • the edges and the base may be provided with complementary locking formations 114, to prevent relative movement of the stacked containers.
  • Each of the end walls 106 carries a retractable stacking element 116, that may be deployed to allow stacking with a nestable container.
  • the retractable stacking element is shown in more detail in Figures 3-6 and comprises a pivotable support bar, mounted in a recess 118 on the inner face of the carrying wall 106, adjacent its upper edge 112.
  • the support bar 116 is attached to the end wall by means of a pivot 120, allowing it to be deployed as shown in Figures 3 and 5 , or retracted within the recess 118 as shown in Figures 4 and 6 .
  • a spring element 122 attached to the support bar engages the rear face of the recess 118 and urges the support bar outwards into the deployed position. The support bar may however be pushed back into the recess 118 against the resilience of the biassing member 122.
  • the stacking elements 116 In use, when the container is in an erected condition, the stacking elements 116 automatically adopt the deployed condition as shown in Figures 3 and 5 , owing to the resilience of the biassing elements 122. This allows the container to be stacked with a nestable container, without the nestable container intruding significantly into the enclosed volume of the container.
  • the container can also be column stacked with similar collapsible containers, which engage the upper edges 112 of the walls 104,106.
  • the end walls 106 are collapsed first and laid flat against the base 102.
  • the locking formations 110 are such that they can be released simply by pressing on the end walls 106.
  • the stacking elements 116 engage the base, they are pushed back into the recesses 118 against the force of the resilient biassing elements 122.
  • the side walls 104 are then folded down on top of the end walls 106.
  • Erecting the collapsed container for use is simply a reverse of the procedure described above.
  • the side walls are lifted first, followed by the end walls 106, which are locked into position by the locking formations 110.
  • the stacking elements 116 deploy automatically, under the force of the resilient biassing elements 122.
  • the first container described above provides a number of important advantages over the prior art.
  • the end walls 106 have to be folded before the side walls 104, the side walls 104 cannot easily collapse during a washing process. This makes the process more reliable.
  • the stacking elements 116 do not protrude far into the open mouth of the container, they do not significantly restrict access to the goods in the container. The stacking elements are deployed and retracted automatically, avoiding the need for a laborious manual operation. The risk of damage to the goods through failure to deploy the stacking bars is also avoided.
  • the container is also suitable for automatic filling owing to the small intrusion of the stacking elements into the mouth of the container and the fact that the stacking elements can be easily retracted into the recesses in the end walls if necessary during the filling operation.
  • the stacking elements also allow slide stacking from the sides of the container. Finally, when the container is in a collapsed condition, it occupies less than 25% of the volume when it is in an erected condition, thereby providing greater economies in shipping costs.
  • the resilient biassing elements can be formed as separate components or they can be moulded as parts of the supporting walls.
  • Embodiments 2 to 6 are provided as background art useful for understanding the invention.
  • the second container 200 shown in Figures 7-12 comprises a substantially rectangular base 202, two side walls 204 and two end walls 206.
  • the side walls and the end walls are attached to the base 202 by means of hinges 208, which allow the walls to be folded flat onto the base 202 for storage or transportation in a collapsed condition, as shown in Figure 8 .
  • the end walls 206 are folded first and that in the collapsed condition they lie adjacent to the base 202.
  • the side walls 204 are collapsed after the end walls 206 and in the collapsed condition overlie the end walls 206.
  • Complementary locking formations 210 are provided on the end walls and the side walls, to lock the walls together when the container is in the erected condition as shown in Figure 7 .
  • the locking formations 210 are conventional and will not be described in detail.
  • the upper edges 212 of the side walls 204 and the end walls 206 are designed to receive the edges of the base 202 of a similar container when the containers are stacked in an erected condition.
  • the edges and the base may be provided with complementary locking formations to prevent relative movement of the stacked containers.
  • Each of the side walls 204 carries a retractable stacking element 216, that may be deployed to allow stacking with a nestable container.
  • the retractable stacking element is shown in more detail in Figures 9-12 and comprises a pivotable support bar, mounted in a recess 218 on the inner face of the carrying side wall 204, adjacent its upper edge 212.
  • the support bar 216 is attached to the end wall by means of a hinge 220, allowing it to be deployed as shown in Figures 9 and 12 , or retracted within the recess 218 as shown in Figures 10 and 11 .
  • the support bar is urged outwards into the deployed position by gravity and is supported in that position by an inclined wall 221.
  • the support bar may however be pushed back into the recess 218 when necessary.
  • the support bar 216 includes a lower part 216a, a middle part 216b, and an upper part 216c.
  • the lower and upper parts 216a,216b are inclined outwards from the side wall 204, and the middle part 216b is substantially horizontal.
  • the upper edge of the upper part 216c engages the underside of a stacked container.
  • the upper part 216c includes a number of notches 222, which allow it to fold flat against the folded end walls 206.
  • the ends of the support bars 216 are received in shaped recesses 224 provided in the end walls 206, when the container is in an erected condition with the stacking elements deployed (see Figure 9 ).
  • the support bars 216 thus provide a secondary locking function, to prevent the end walls from being folded inwards.
  • the support bars 216 are first retracted into the recesses 218 in the side walls 204 as shown in Figure 10 . This allows the end walls to be folded flat against the base 202, followed by the side walls 204.
