Definitions

  • This invention relates to a container for the storage and/or transport of goods and in particular to a container which can be folded into a smaller size when it has been emptied of goods, so that it consumes less volume when returned for refilling or reuse.
  • a shortcoming associated with some collapsible containers is that different designs have been required for different applications. That is, a container intended for contents of high specific gravity was, out of necessity, of a substantially different design and construction to a container intended for contents of low, specific gravity.
  • a further problem with one class of known collapsible containers is that the side wall panels are pivotally connected to the base and they fold over so as to lay one atop the other atop a base.
  • a problem with this is that the side wall panels must be different sizes (the lowest panel in the stack being the longest, and the uppermost the shortest), so they are not interchangeable.
  • a container comprising a base, and a plurality of side wall assemblies, where each side wall assembly is comprised of a plurality of pivotally interconnected triangular elements, and each side wall assembly is adapted to fold from an erected state in which each side wall assembly is upstanding from the base, to a collapsed state in which a remainder of the elements in a respective side wall assembly sit atop a first element thereof, and each of the collapsed side wall assemblies sit alongside one another and atop the base.
  • each of the collapsed side wall assemblies sit alongside one another and atop the base without overlap between the collapsed side wall assemblies.
  • a side wall assembly comprises a lowermost element, this being the first element, four side elements, and an uppermost element.
  • the lowermost and uppermost elements are isosceles triangles of substantially the same shape and size, and the side elements are also isosceles triangles, each approximately one half the size of the upper and lowermost elements.
  • each side wall assembly is connected to the base by virtue of the lowermost element being pivotally attached to the base, and so the folding action when collapsing the container is a combined inward and downward action with respect to the base.
  • the container comprises a lid which is adapted to sit atop the erected walls of the container.
  • the base is square
  • the container comprises four side wall assemblies.
  • each wall assembly comprises a first locking means adapted to lock the wall assembly to an adjacent wall assembly, and a second locking means adapted to lock the lid to the wall assembly.
  • the invention may be said to include a container comprising a base, a plurality of side wall assemblies that are adapted to fold from an erected state in which each side wall assembly is upstanding from the base, to a collapsed state, each side wall assembly being comprised of a plurality of pivotally interconnected triangular elements, where selected edges of each element in a side wall assembly have profiles that create engagement between that element and an adjacent element in that wall assembly when the wall assembly is erected.
  • the invention may be said to include a container comprising a base, a lid, and a plurality of side wall assemblies that are adapted to fold from an erected state in which each side wall assembly is upstanding from the base, to a collapsed state, wherein each of the base, lid and the side wall assemblies are comprised of a plurality of smaller, interconnected elements that are adapted to be removed and replaced if damaged.
  • the invention may be said to include a method for collapsing the above described container, the method including the steps of:
  • the invention may be said to include a method for erecting the above described container, the steps for the method being the reverse of the method for collapsing the container described above.
  • the invention may be said to include a container comprising a base, and a plurality of side wall assemblies, where each side wall assembly is comprised of a plurality of pivotally connected elements, where contiguous edges of at least two adjacent elements incorporate means for controlling relative rotation between the two elements about the contiguous edges thereof.
  • said means transmits torque between said adjacent elements.
  • said means comprises meshing splines.

  • Figure 20 is a perspective view of a side wall assembly according to a further embodiment.
  • Figure 21 is a perspective view of the side wall assembly in Figure 20, where this is viewed from the opposing side to that illustrated in Figure 20.
  • FIG. 1 where there is illustrated a container 1 comprising a square base 2, four side wall assemblies, and a lid 4 seated atop the side wall assemblies. Three of the four side wall assemblies 6 are identical. A fourth side wall assembly 8 differs from the three identical side wall assemblies 6 only in as much as it incorporates provisions for an outlet (such as for fluidised materials) at 10.
  • the base 2 (see Figure 12) is constructed like a pallet, with apertures 3 for fork lift tines.
  • the base 2 is an assembly comprised of four almost identical plate modules 50 and four identical foot modules 52.
  • Each foot module 52 has a square footprint with an upwardly extending rectilinear column 56 at each corner thereof, each column being connected to another two columns 56 by a web 57.
  • a square plate module 50 sits atop the columns 56 of the foot module 52 and interlocks therewith, so that an upper surface of the plate forms the floor of the container 1.
  • Each foot module 52 and plate module 50 has edge features along two intersecting edges 51, 53 thereof such that each module 50 and 52 is adapted to interlock with like modules along these edges in order to form the base 2.
  • An advantage of constructing the base 2 in this modular fashion is that if one or more modules 50 or 52 should be damaged such as by impact from a forklift tine or the accidental dropping of the container 1 , then any damaged modules 50 and/or 52 can be replaced.
  • hinge pin supports 58 Extending upwardly from the upper surfaces of base plate modules 50 along two intersecting edges thereof are a plurality of spaced apart hinge pin supports 58 (see Figures 12 and 15). These hinge pin supports 58 have aligned apertures 59 passing through them, so that a hinge pin 60 may be passed through the hinge pin supports 58 of a pair of interconnected base modules 50 for the purpose of retaining a side wall assembly 6, 8 thereto.
  • each side wall assembly 6, 8 is comprised of a plurality of pivotally interconnected triangular elements, these being a triangular lowermost element 20, four triangular side elements 22 and 24, and a triangular uppermost element 26.
  • each side wall assembly 6, 8 incorporates a pair of diagonally intersecting 'fold lines' extending between the corners thereof so as to form an 'X', and a horizontal fold line extending across the wall assembly, so that the three fold lines intersect near the geometric centre of the wall assembly 6, 8, in this case.
  • the geometry of the elements and their fold lines contributes not only to the advantageous manner in which the side wall assembly folds, but also to the way in which loads are transmitted through the elements of these side wall assemblies.
  • the lowermost element 20 of each side wall assembly 6 and 8 is pivotally attached to the base 2 of the container 1 along a longest edge thereof.
  • Lowermost element 20 includes hook shaped hinge portions 21 which are sized and positioned along the longest edge thereof so as to interleave with the hinge pin supports 58 of base plate modules 50.
  • These hook shaped hinge portions 21 define aligned apertures 23, so that the hinge pin 60 may be passed through the hook shaped hinge portions 21 for the purpose of pivotally connecting the side wall assemblies 6, 8 to the base plate modules 50.
  • One each of the side elements 22, 24 is pivotally attached to one each of the remaining (equal length) sides of the lowermost element 26.
  • a further side element 22, 24 is pivotally connected to each of the first two side elements 22, 24.
  • the uppermost element 26 is pivotally connected to one each of the further side elements 22, 24 along its sides of equal length.
  • Each of these elements 20 through 26 is connected to the other elements in the side wall assembly 6, 8 via a series of spaced apart links 40.
  • Each link 40 has a pair of parallel holes 42 passing there through, there being one of the holes 42 toward each end of the link 40.
  • a plurality of spaced apart recesses 44 are provided in edges of elements that are to be connected with other elements via these links 40. Each of these recesses 44 is sized so as to accept an end of a link 40.
  • edge portions 46 of elements that are between and/or to either side of recesses 44 have aligned apertures passing through them so that a further hinge pin 60 (see Figure 1 1) may be passed through both these edge portions 46 and the links 40 thereby pivotally connecting these.
  • each side wall assembly 6, 8 is adapted to fold from an erected state in which the side wall assembly is upstanding from the base 2 (as illustrated in Figures 1 and 9), to a collapsed state in which a remainder of the elements 22, 24 and 26 in a respective wall assembly 6, 8 sit atop the lowermost element 20, which in turn sits atop the base 2 (as illustrated in Figure 3).
  • a significant feature of the exemplary container is that at least two edges of each element in a wall assembly have profiles that permit some degree of interlock between that element and an adjacent element when the wall assembly 6, 8 is erected.
  • link 40 is represented by a solid line extending between the two pivot points A and B.
  • Each of the pair of elements is equipped with one of a matching pair of edge profiles 102 and 104, where a first profile 102 is characterised by an outwardly projecting ridge 106, and the second profile is characterised by a recess 108 which is sized and shaped so as to accept the ridge 106 therein when the wall assembly 6, 8 is erected.
  • Each of the matching pair of edge profiles 102 and 104 incorporates a rounded portion 1 10 that extends between (so as to blend) a first side 112 of each element (which may be either of an inner side or an outer side depending on the elements) to either of the ridge 106 or recess 108 in the end profile 102 or 104 respectively.
  • a ledge 1 1 1 Extending between the ridge 106 and a second side of the lower element is a ledge 1 1 1.
  • a shoulder 1 12 Extending between the recess and a second side of the upper element is a shoulder 1 12 which, when the wall assembly is erected, is adapted to abut against the ledge 111 of the lower element.
  • FIG 11a where the two elements are illustrated lying down (i.e. the container 1 is in its folded state), the upper element laying atop of the lower element (in this case), and the first sides (again, in this case) of the two elements being in contact.
  • Figure l ib the curved surfaces of the two elements bear against and rotate relative to one another, and this continues through Figures 1 Ic through l ie, until the ridge 106 locates within the recess 108 and the shoulder abuts 112 against the ledge 111 as shown in Figure 1 If, this being when the side wall assembly 6, 8 is erected.
  • FIG. 1 If that the joint created between the two elements permits one element to rotate through 180 degrees relative to the other, the joint locking if any attempt is made to force its rotation beyond this 180 degrees.
  • FIGs 20 and 21 where there is illustrated a side wall assembly 6a that is very nearly the same as the side wall assembly 6 discussed above, but with one important distinction.
  • the rounded portions 1 10 of each of edge profiles 102 and 104 extending in at least the regions between links 40 of selected panels incorporate a series of teeth or splines 300 extending lengthwise along them.
  • the teeth or splines 300 of adjacent elements (20a and 22a, and 24a and 26a respectively) mesh and transmit rotational torque between these elements so that the erection and collapse of side wall assembly 6a (i.e. the relative rotation between the two elements about the contiguous meshing edges thereof) occurs in a very controlled, progressive and precise fashion, with all elements in the side wall assembly 6a reaching both the fully erected and fully collapsed state at exactly the same time.
  • each of edge profiles 102 and 104 of elements 22a and 24a do not incorporate these teeth or splines 300 (although optionally they may do), as their inclusion is not necessary for the purpose of effecting controlled, progressive and precise erection and collapse of side wall assembly 6a.
  • the incorporation of splines 300 at these points may create an internal pinching hazard for container contents, where such a pinching hazard would prove especially perilous for liquid carrying plastic bags within the container.
  • the lid 4 is an assembly comprised of four identical plate modules 4a that may be either hot plate welded or mechanically fastened together. Each lid module incorporates a moulded retaining corner detail 5, which allows for registration of stacked units.
  • Lowermost element 20 incorporates an integrally formed pin portion 20a at its apex
  • the uppermost element 26 an integrally formed, c-shaped recess 26a at its apex that is adapted to accept the pin portion 20a of the lowermost element 20 therein in a releasably engageable fashion.
  • each wall assembly comprises a first locking means 200 adapted to lock one wall assembly (such as wall assembly 6 in Figure 1) to an adjacent wall assembly (such as wall assembly 8 in Figure 1), this then being in effect a 'lateral' locking means.
  • first locking means 200 adapted to lock one wall assembly (such as wall assembly 6 in Figure 1) to an adjacent wall assembly (such as wall assembly 8 in Figure 1), this then being in effect a 'lateral' locking means.
  • Each lateral locking means 200 comprises a latch 202 operated pin 204 which acts to capture the adjacent wall assembly. In this way, each wall assembly 6 or 8 is locked to adjacent wall assemblies 6 or 8 along both edges thereof, and at the top and bottom of each edge thereof via each of the upper 22 and lower 22 side elements thereof, this then providing secure lateral locking between side wall assemblies 6 and 8.
  • each wall assembly 6, 8 comprises a second locking means 220 adapted to lock the lid 4 to this.
  • This lid locking means 220 comprises a lever 222 which is pivotally attached to the lid 4 at a first end, the handle having a lug 224 projecting there from which registers in an arcuate track 226 formed into an uppermost element of the side wall assembly 6 or 8. Rotation of the handle through 90 degrees from a horizontal orientation to a vertical one moves the lug 224 along and down the track 226 so that the side wall assembly 6 or 8 (and so the remainder of the container) captures the lid 4.
  • Figure 2 illustrates a collapsed container (i.e. a container that has been folded down into its collapsed state) with its lid 4 removed (lid 4 can be laid atop side wall assemblies 6 and 8).
  • a second side wall assembly 8 is illustrated partially but not fully erected.
  • this second wall is illustrated fully erected and locked to the first erected side wall.
  • FIGs 8 and 9 a third and fourth wall respectively have been erected and locked to adjacent walls. With all four side walls erected and interlocked, the erected container can be filled and the lid applied and locked in position.
  • An advantage of this exemplary container 1 is its modular construction, so that if one element in the container is damaged and rendered inoperable, that element (or just a portion thereof) may be easily replaced. If just a portion (e.g. a side element 22) of an element (e.g. side wall assembly 6) is damaged, then that portion can be replaced without necessitating the replacement of the entire element.
  • a further advantage is that the container 1 is adapted to fold down in to a very compact state whilst employing side panel assemblies which are substantially identical and therefore interchangeable.
  • a further advantage of the container 1 is that it may be modified by the use of strengthened hinge pins 60 to increase its strength and thereby increase its load carrying capacity. Where a container is to carry lighter loads, lower strength hinge pins 60 made of low grade plastic, aluminium or the like may suffice. Where a container is to carry heavy loads however, higher strength hinge pins 60 of steel, engineered plastic, reinforced plastic or composites may well be required. An advantage of the container 1 then is that the pins 60 of the container can be interchanged as required.
