Definitions

  • a container according to this invention is formed from a single moulding of a plastics material such as polyethylene to form a box or transport case which comprises a bottom panel and first and second pairs of like wall panels hingedly connected to the bottom panel.
  • a lid or cover may be provided preferably as a separate item to close the open top of the box.
  • Containers according to the invention may also be stacked one upon the other so that it is often unnecessary to provide a lid for each container.
  • Non-collapsible cases with insulating properties for shipping fish and formed from expanded or foamed polystyrene are known but these known cases are not returnable and have become regarded by virtue of their composition, as being environmentally unacceptable.
  • a collapsible, returnable and reusable container is desirable for the shipping of fresh (chilled) or frozen fish.
  • a unitary knockdown foamed polystyrene shipping container is know from US- A-3 675 808 but is not robust enough for repeated return (round- trip) journeys. Moreover, the foamed material, at least to some extent, absorbs fluids and would on this count alone be unsuitable as a reusable fish box.
  • US-A-4 235 346 discloses a lightweight collapsible shipping container having a unitary moulded construction in which a bottom panel is integrally hinged to four peripheral side panels and a top panel is hinged to one of the side panels. However, this container is also intended to be formed from a foamed plastics material and is unsuitable for use as a reusable fish box for the reasons given above.
  • Collapsible containers having a more robust and acceptable composition are known from e.g. US-A-4 005 795 which discloses a container formed from a unitary blank of polypropylene in which side panels are integrally hinged to a bottom panel. There are provisions to lock together with side and end panels when they are brought into an upright position comprising stud and socket connections. However, the particular arrangement disclosed is insufficiently secure in view of the anticipated static and impact loading imposed upon a container according to the present invention utilized as a shipping container for fish.
  • US-A-3 675 808 discloses a collapsible box in which the side and end panels are secured together by means of a dovetail type tongue and recess.
  • the present invention seeks to achieve a robust but relatively low cost collapsible, returnable and reusable shipping container which for return shipment, can be put into nested superposed relationship with like containers, when collapsed so that the height and space occupied by a stack of collapsed containers is minimized.
  • the present invention provides a collapsible container for use in the shipping of goods, including perishable goods, and comprises a single moulding of a plastics material to form an open-topped box which comprises a bottom panel and first and second pairs of like wall panels hingedly connected to said bottom panel and wherein each wall panel and said bottom panel are integrally hinged together so that the walls can be erected from a collapsed position to an upright position and vice versa, wherein complementary locking means are provided at adjacent edges of said first and second pairs of wall panels so that said side and end panels are mutually lockable, when the corners of the container are formed by putting the wall panels into an upright attitude, wherein said container is adapted to nest in superposed relationship with respect to another like container when said containers are in collapsed condition so that the height of a stack of collapsed containers is minimized.
  • said panels may include features which protrude beyond the medial planes of said panels, said features being formed and positioned so as to permit nesting of superposed containers.
  • said locking means may comprise a retaining face provided by the panels of one pair of panels engagable with a retaining face provided by the panels of the other pair of panels to prevent collapse of said wall panels.
  • the retaining face of a panel of one pair of panels may be mutually engaged with the retaining face of a panel of the other pair of panels when the corners of the container are formed and locked thereby to prevent collapse of the containers.
  • the retaining face of said one panel may be provided by a rib adjacent an end face of that panel.
  • the rib may be received in a channel provided by the said other panel, one face of the channel providing the retaining face of the other panel to prevent collapse of the one panel.
  • a releasable locking face is hinged to said other panel for engagement with the retaining face of said one panel to prevent collapse of the other panel.
  • the locking face is carried by a locking flap hinged to said other panel which locking flap is integral with other panel and forms a part of said retaining channel face when locked.
  • said locking face may comprise a rib extending perpendicularly from said locking flap.
  • said locking rib and said one panel may comprise releasable complementary fastening means.
  • said complementary fastening means are a push-snap fit.
  • said fastening means comprise complementary notches and pegs formed along the mating adjacent vertical edges of said first and second pairs of wall panels and which are hinged into engagement when the locking flap is engaged after said wall panels are put into their fully upright positions to form said box.
  • a secondary retaining face may be provided within the channel of said other panel to engage an end edge of said one panel within said channel.
  • said wall panels may be formed with integral handling recesses adjacent their uppermost ends.
  • the underface of said bottom panel of one container may be formed with locating means adapted to engage complementary locking means formed upon an uppermost rim of another like container, said complementary locating means being engagable to enhance secure stacking of those containers.
  • the complementary locating means formed upon said uppermost rim may be adapted to engage locating means provided on the underside of a lid so that the lid can be secured to close said container and wherein the upwardly exposed face of said lid also includes locating means adapted to be engaged by the said locating means provided on the underface of the bottom panel of another like container thereby to enhance secure stacking of those containers.
  • each wall panel and said bottom panel may be continuous along the length of the respective wall panel.
  • said container may be substantially sized to fit a standard European pallet measuring 1.2 x 0.8m for return shipment when said container is in a collapsed substantially flat condition.
  • a collapsible container for use in the shipping of goods which comprises a single mounding of a plastics material to form an open-topped box which comprises a bottom panel and first and second pairs of like wall panels hingedly connected to said bottom panel and wherein each wall panel and said bottom panel and first and second pairs of like wall panels hingedly connected to said bottom panel and wherein each wall panel and said bottom panel are integrally hinged together so that the walls can be erected from a collapsed position to an upright position and vice versa, wherein complementary locking means are provided at adjacent edges of said first and second pairs of wall panels so that said side and end panels are mutually lockable, when the corners of the container are formed by putting the wall panels into an upright attitude, said locking means comprises a retaining face provided by the panels of one pair of panels engagable with a retaining face provided by the panels of the other pair of panels to prevent collapse of said wall panels, wherein the retaining face of said one panel is provided by a rib adjacent an end
  • FIGURE 1 is a plan view of a unitary blank of moulded plastic material comprising a base panel and four integrally hinged wall panels from which the box can be formed, three of the wall panels being partly raised;
  • FIGURE 2 is a perspective view of an erected open-topped container formed from the blank shown in Figure 1;
  • FIGURE 3 is a perspective view of an erected open-topped container formed from the blank shown in Figure 1 and also comprising a fitted lid;
  • FIGURE 4 is a perspective view of the container showing the underside of the base panel
  • FIGURE 5 is an end view showing the end wall panel along an edge with the locking flap in coplanar relationship with respect to the end wall panel;
  • FIGURE 6 is an end elevational view of a partially-erected open- topped container formed from the blank shown in Figure 1, as viewed from an end of the container that has its end wall pivoted downward, further illustrating the elements shown in Figure 5;
  • FIGURE 7 is the same end elevational view of a partially-erected open-topped container as is illustrated in Figure 6 but wherein the blank of Figure 1 possesses additional elements;
  • FIGURE 8 is a perspective view of an open-topped container formed from the blank shown in Figure 7.
  • FIG. 1 there is shown a unitary blank 10 of moulded suitable plastic material comprising a rectangular bottom panel 12 to the peripheral edges of which are hinged first and second pairs, 14, 14a and 16, 16a respectively, of like wall panels
  • Side wall panels 14, 14a are hinged to the opposed longitudinal peripheral edges of bottom panel 12 along integral continuous hinges 18, 18a so that the wall panels can be erected from the collapsed position, in which they are substantially co- planar with the bottom panel, until they are upstanding substantially normal to the bottom panel, and vice versa.
  • end wall panels 16, 16a are hinged to the opposed transverse peripheral edges of bottom panel 12 along integral hinges 20, 20a.
  • Hinges 18, 18a and 20, 20a sometimes referred to as "living hinges," comprise integrally moulded continuous strips of plastics material which are moulded together with the panels of the blank and are significantly thinner and hence more flexible than the wall thickness elsewhere in the blank. Although such continuous hinge strips will usually be formed from the material injected during the moulding process to form the panels of the blank, other hinge constructions are envisaged.
  • FIG. 2 In order to maintain the wall panels upright to form the open topped container the side wall panels are locked to the end wall panels.
  • the opposed vertical edges of the end wall panels are each provided with a locking flap "f" which engages the external face of a side wall and is locked to it in a snap-fit.
  • the vertical internal face of the end wall adjacent each end edge is formed with a channel "C,” the outermost wall 22 of which provides a retaining face to prevent collapsing movement of the side walls, e.g. side wall 14 is furnished, adjacent its end edge, with an integral perpendicular flange or rib 24.
  • Locking flap "f” is integrally hinged to the end edge of the end wall and includes a perpendicular locking rib 26.
  • the side wall is formed with a pair of spaced pegs 28 located behind rib 24.
  • Pegs 28 locate as a "snap-fit" into spaced notches 30 formed in the locking rib 26.
  • a secondary locking rib 32 is formed within channel "C" against which the extreme end face 33 of the side wall panel engages and thereby gives better locking security and a more positive engagement of the wall panel edges when the corner of the container is being formed.
  • the end walls are formed, adjacent their top ends with an inwardly projecting recess 34 which not only increases the vertical compression strength and the rigidity of the end wall but provides a handle feature for the end walls of the box.
  • Similar handle recesses 36, 38 respectively, are formed in each of the side walls of the container, each recess 36 and 38 being separated by horizontal 40 and vertical 42 ribbing of the external face of the wall which improves the stiffness and stacking strength of the longer side wall panels.
  • Each of the wall panels includes an inwardly directed top flange 44, 44a and 46, 46a, respectively, which together form a raised upper rim R of the container when the wall panels are in their erected positions.
  • Top lid “L” ( Figure 3) has a peripheral complementary channel (not shown) which can be snap-fitted onto the raised rim R of the container.
  • a peripheral complementary channel (not shown) which can be snap-fitted onto the raised rim R of the container.
  • a series of upstanding lips 48 and 48a and the underside of bottom panel 12 is formed, adjacent its periphery, with a peripheral channel 50 ( Figure 4) so that the lip of the lid “L” of an upper container can be located in the channel 50 of a lower container to facilitate locking and enhance stacking stability.
  • the lid “L” also includes two pairs of transverse lips 52, 52a which are received in a relieved section 54 of the bottom panel of another like container. Lips 48, 52 and 48a, 52a so that each of those above groups engages and half of the bottom panel of a container stacked transversely thereon.
  • FIG 7 is the same end elevational view of a partially-erected container as is illustrated in Figure 6, and, simultaneously, also referring to Figure 8, additional elements of the container are illustrated.
  • a tab-like member 56 protruding from each channel "C” and a corresponding complementary notch 58, formed in each respective perpendicular flange or rib 24, for receiving the tab member 56.
  • a tab member 56 and corresponding complementary notch 58 are formed and aligned to engage one another when the ends of end walls 14, 14a and side walls 16, 16a are brought into contact with one another.
  • the tab member 56 is tapered, or bevelled, so that its narrowed leading end can easily engage the corresponding complementary notch 58.
  • each tab 56 is forced through a corresponding complementary notch 58 until the flared, or wider, portion of the tab member 56 extends into the complementary notch 58. It is the forcing of the flared tab member 56 through the complementary notch 58 which brings the edge of an end wall 14, 14a into desired alignment with the edge of a side wall 16, 16a.
  • Each perpendicular locking rib 26 may be modified to facilitate engagement of each notch 30 in a locking rib 26 with a corresponding peg 28 (not visible in Figures 7 and 8 but previously discussed above).
  • a secondary notch 60 is placed in the locking rib 26 near each notch 30 to form a secondary peg 62.
  • the secondary peg 62 that is formed is flexible due to the notches 30, 60 on either side. The flexibility of the secondary peg 62 helps alleviate possible difficulty in snapping the pegs 28 into the notches 30 which may be caused by slight misalignment of the pegs 28 and respective notches 30.
  • the use of the secondary peg 62 in the locking rib 26 greatly reduces or eliminates the rigidity and inflexibility of the locking rib 26 when optimum alignment between the pegs 28 and respective notches 30 does not occur.
  • the panels of the blank are configured so that a stack of blanks can be formed with the blanks disposed in superposed nested relationship.
  • moulded features of each panel are all contained with a common plane on either side of a medial plane of that panel.
  • certain features are adapted to nest in other like features such as the handle recesses of the wall panels.
