Definitions

  • the invention relates to a collapsible box with a bottom, a first sidewall and a second sidewall extending parallel to the first sidewall, wherein the box is configured to automatically collapse under vertical pressure in a substantially uniform manner.
  • the invention further relates to a set of such collapsible boxes.
  • the US 201 1/0309134 A1 discloses a collapsible box formed from cardboard with four sidewalls and a rectangular bottom. Each sidewall comprises several scores which extend parallel to the bottom along the width of the sidewall. The scores are configured to facilitate the collapsing of the box or carton when for instance another box is set on the carton to form a stack. The weight of the upper box presses down on the lower box which, due to the scores in the sidewalls, collapses in a substantially uniform manner. When the lower box has been collapsed, the sidewalls comprises pleats which are defined by the scores. The pleats of opposite sidewalls of the box have a same distance to the bottom.
  • the vertical size of the box can be adjusted in dependence on the filling degree of the box. If for instance the content of the box does not completely fill the interior space of the box, the box, when being pressed down, will be collapsed up to a level at which a lid of the box abuts against the content. The downwardly directed force is then mainly supported by the content of the box.
  • cartons are often set on a pallet on which more than one layer constituted by several cartons are stacked on each other.
  • the above mentioned scores and the pleats resulting thereof should allow the cartons to be collapsed in a substantially uniform manner, the non-uniform collapsing cannot be excluded completely. Cartons higher in the stack are therefore prone to slanting and - worst case - to falling down from the stack. Therefore, there is a need to stabilize stacked cartons on the pallet when being collapsed due to vertical pressure.
  • One object of the present invention is to provide a collapsible box which can be collapsed in a substantially uniform manner and contributes to the stability of a set of collapsible boxes placed side by side and loaded by a vertical force.
  • the object is achieved with a collapsible box having the feature of claim 1.
  • Embodiments and developments of the invention are the subject matter of the claims which depend on claim 1 .
  • a first pleat of the first sidewall is directed inwardly to the interior of the box while a second pleat of the second sidewall is directed outwardly opposite to the interior of the box.
  • the first pleat and the second pleat have the some distance to the bottom of the box.
  • the interlocking between the two cartons leads to a compact unit within a stack of boxes, thus increasing the stability of the stack when the boxes are subject to vertical pressure.
  • the interlocking functions in different directions. Firstly, there is a kind of positive fit in a vertical direction. Secondly, when the outwardly directed pleat is clamped or trapped by the inwardly directed pleat, frictions forces between the pleats hinders the adjacent boxes to be moved relative to each other in a horizontal plane.
  • the collapsing box according to the invention can preferably be used to pack powder like detergent powder. Once bagged and packed, the volume of detergent powder decreases due to different reasons. Therefore, the volume of the powder at the moment of packing differs from the final volume at the warehouse.
  • the powder In case of using a carton which is completely filled up with a detergent powder, the powder itself can carry most of a vertical load in a stack of cartons.
  • the carton as such has to bear only a part of the load, what allows the carton to be designed simple and cost effective.
  • the detergent powder loses a part of its initial volume, the interior of the carton will not be filled up completely anymore. Consequently, the sidewalls of the cartons have to bear the complete load.
  • the load on top of the carton causes the sidewalls to collapse in a uniform matter by creating pleats so that the height of the carton becomes smaller, until the powder within the carton comes in contact with the lowered lid of the carton and therefore begins to absorb again at least a part of the top load.
  • the volume of the detergent powder decreases with the time, the combination of the collapsible box with the powder filled therein guarantees that powder always contributes to the absorption of the top load. This leads to savings during the entire supply chain.
  • the first sidewall comprises at least two scores extending parallel to the bottom, wherein an upper score is located on an inner surface of the first sidewall and wherein a lower score is located on an outer surface of the first sidewall.
  • the upper score causes the material of the sidewall to be bent inwardly while the lower score causes the material of the sidewall to be bent outwardly.
  • the scores defines the inwardly directed pleat. Instead of the edge there can be provided a further score located above the upper score so that these three scores define the pleat.
  • the second sidewall can comprise at least two scores extending parallel to the bottom, wherein an upper score is located on an outer surface of the second sidewall and wherein a lower score is located on an inner surface of the first sidewall.
  • the two scores can be combined with an edge between the lid and the second sidewall or with a further parallel extending score in order to define the outwardly directed pleat.
  • the first sidewall When being collapsed by a top load, can comprise more than the first pleat, for instance two, three or four pleats.
  • all pleats of the first sidewall are directed inwardly, preferably all pleats have a same buildup.
  • the outer surface of the first sidewall defines a main plane of the first sidewall wherein all pleats do not extend beyond this plane but extend starting from the plane in the direction of the interior of the box.
  • all pleats of the first sidewall do not necessarily have to be directed inwardly.
  • the first sidewall shall have a pattern of pleats which corresponds to a counter pattern of pleats of the second sidewall so that, at respective heights of the sidewalls, any of the pleats of the first sidewall can engage into the recess of the corresponding counter pleat of the second sidewall and vice versa.
  • the box comprises a third sidewall and a fourth sidewall extending parallel to the third sidewall and perpendicular to the first sidewall and the second sidewall, respectively.
  • the bottom of this embodiment is rectangular.
  • the third sidewall comprises a third pleat and the fourth sidewall comprises a fourth pleat, wherein a height of the third pleat substantially equals a height of the fourth pleat, and wherein the third pleat is directed inwardly to the interior of the box and the fourth pleat is directed outwardly opposite to the interior of the box.
  • the third sidewall and the fourth sidewall can comprise more than only one pleat when being collapsed.
  • the third pleat on the third sidewall and the fourth pleat on the fourth sidewall can create a further interlocking between boxes placed adjacent to each other. Assuming that nine carton are placed in three rows each of the rows comprises three cartons, there will be an interlocking between cartons of the same row (by the first pleat and the second pleat) and an interlocking between adjacent rows (by the third pleat and the fourth pleat).
  • the height of the third pleat and the fourth pleat can substantially equal the height of the first pleat and the second pleat.
  • the pleats of the third sidewall and the fourth sidewall can have a vertical offset to each other.
  • Another object of the invention the providing a set of collapsible boxes, wherein the set has an enforced stability, is achieved by the subject matter of claim 6.
  • Embodiments of this invention are described in the claims depending on claim 6.
  • a first box and at least a second box are placed side by side, wherein a second sidewall of the first box abuts on a first sidewall of the second box, wherein, when the boxes are collapsed by vertical pressure, the outwardly extended pleat of the second sidewall of the first box extends into a recess of the second box, the recess being formed by the inwardly directed pleat of the first sidewall of the second box.
  • At least a third box is placed side by side to the first box, wherein a fourth sidewall of the third box abuts on a third sidewall of the first box, wherein, when the boxes are collapsed by vertical pressure, an outwardly extended pleat of the fourth sidewall of the third box extends into a recess of the first box, the recess being formed by a third inwardly directed pleat of the third sidewall of the first box.
