Definitions

  • This invention relates to collapsable containers.
  • Known collapsable containers having four sides hinged together at their vertical edges and having bottom and top members each hinged to one of the four sides have their closed positions by conventional locking members such as hasps and hooks or else the top and bottom mem bers have been provided with deep flanges which embrace free edges of the side members when the container is closed.
  • the known containers required the use of specially arranged hinges having straps and hinge pins.
  • a collapsable container having front, rear and side panels each having each of its vertical edges connected to the adjacent vertical edges of the next adjacent panels, a bottom panel having one edge connected to the lower edge of either of the front or the rear panels and a top panel having one edge connected to the upper edge of either of the front or the rear panels, the connections being such that all the panels are adapted to be collapsed to bring the broad surfaces of the panels together, is characterised in that the bottom panel is arranged, when the panels are erected, to be held in its closed position by a resilient flap which is secured to one panel of a pair of panels comprising the bottom and a side panel and is bendable out of the plane of a broad surface of the said one panel to enable it to enter and be frictionally engaged in a slot provided by a member attached to the other of the pair of panels and by the said other panel, the top panel being likewise arranged to be held to a side panel by a like bendable flap.
  • each edge of both the bottom and the top panels are held to an adjacent side panel by a bendable flap.
  • each flap which connects a side panel with a top or bottom panel is a metal strip having a longitudinal extending corrugation, the side of the strip on one side of the corrugation being secured to a panel and the corrugation being disposed so as to provide a rounded corner when the other side of the strip is inserted in a slot.
  • the panels may each be made of a cheap, readily available material for example plywood or hardboard which forms self-supporting panels from their sheet.
  • the strips may be made of any suitable material, for example tinplate, and may be attached to the panels by rivets or other conventional means.
  • FIG. 1 is a perspective view of a partly erected open box
  • FIG. 2 is a perspective view of a closed box
  • FIG. 3 is a perspective view on an enlarged scale of a corner of a box
  • FIG. 4 is a perspective view of a collapsed box.
  • a collapsable container comprises a front panel 1, side panels 2 and 3 and a rear panel 4.
  • the panels may be made of 3-ply plywood or hardboard which are stiff enough for the individual panels to be self-supporting.
  • the vertical edges of each of each of the panels 1, 2, Sand 4 are pivotally connected to the vertical edges of the next adjacent panel by thin tinplate strips 7 which, as shown, are riveted by rivets 8 to the panels which they connect.
  • This manner of connecting the panels 1, 2, 3 and 4 together permits the panels to be folded flat with broad surfaces of the panels brought together. Instead of riveting the strips 7 to the panels, they may be held to the panels by stitching in known manner.
  • a bottom panel 5 is pivotally secured to the lower edge portion of the front panel 1 by a thin metal strip 9* which is, in the example shown in the drawings, riveted to the outer surfaces of the panel 1 by rivets 10 and to the outer surface of the adjacent edge portions of the panel 5.
  • a top panel 6 is similarly connected to the rear panel 4 by a thin metal strip 11 which is shown in FIG. 4 in which the box is in its collapsed condition. Erection of the box is a simple and rapid operation.
  • resilient metal flaps 12 are used to connect the bottom panel 5 to each of the panels 2, 3 and 4.
  • This connection is effected with the use of flat rails 14 which are fixed to the lower edge portions of each of the panels 2, 3 and 4 by rivets 15 which fix the two ends of the rails and the upper longitudinal edge portion to the said three panels.
  • the rails are preferably made of plywood. The ends of the rails are placed over the adjacent metal strip 7 and the rivets pass through both the rails, the strips and the panels to which the rails are fixed. The upper longitudinal edge portion of each rail abuts directly on the outer surface of the adjacent panel.
  • the strips 7 act as spacers and in consequence of the manner of attaching a rail to a panel, the rail is placed in tension and slightly bowed to form a slot having a very narrow open mouth at the lower edge of each rail.
  • the metal flaps 12 bear on the outer surfaces of the panels to which they are secured and project, in the collapsed condition of the box, from the panels in substantially the plane containing the surface to which they are attached.
  • Each flap 12 is made, in the example now described, of tinplate which is bent over at the longitudinal edges and free corners of the flap.
  • Each flap has a single corrugation 13 intermediate its longitudinal edges. The flap 12 on one side of the corrugation is riveted to the outer surface of the bottom panel 5.
  • the flaps 12 When the bottom panel is moved to the lower edges of the panels '2, 3 and 4, the flaps 12, having previously been bent, have their free edges inserted in the slots between the various rails 14 and the panels on which they are fixed.
  • the operation of inserting the flaps 12 in the slots is very easily and quickly effected without the exercise of skill.
  • the flaps When inserted, the flaps are frictionally engaged in the slots and hold the bottom panel 5 firmly in its closed position.
  • the top panel 6 is similarly held in its closed position by like resilient bendable flaps 12 which engage in like slots formed between fiat rails 14 disposed at the upper edge portions of the panels 1, 2 and 3, the open mouths of the slots in this case facing upwards.
  • the flap 12 on the bottom panel 5 which engages in the slot formed between the lower edge portion of the rear panel 4 and the rail 14 mounted on this panel may be substantially longer than the flaps which engage slots at the lower edge portions of the panels 2 and 3.
  • the flap 12 on the top panel 6 which engages in the slot formed at the upper edge portion of the front panel 1 may be substantially longer than the flap 12 which engages in the slots at the upper edge portions of the panels 2 and 3.
  • the relatively sharp free edges of the various panels are located within an envelope which contains the rounded bent edges presented by the strips 7 and the flap 12' so that objects which would tend to engage the panel edges and pull the panels apart are less liable to encounter the panel edges.
  • the loaded and closed container may readily be bound by known wire-tying or strip banding machines.
  • the straps 7 may be made of bendable material other than tinplate.
  • Containers embodying the invention may be made in a very wide range of sizes while using cheap, strong and readily available materials.
  • -A collapsable container having four side panels, and top and bottom panels, each panel being formed of rigid non-bendable material, and each of said four side panels being connected at its vertical edges to the adjacent vertical edges of the adjacent side panels, by means of bendable strips secured to the said vertical panel edges, whereby said four side panels can be callopsed to lie flat on one another, and in which said top and bottom panels are each connected to one of said side panels by bendable strips secured to the adjacent edges thereof, and each of said top and bottom panels are further provided with bendable fiaps projecting from at least two edges thereof, and normally lying in the plane of said panel but bendable out of said plane, and at least two of said side panels are provided each with a rail secured thereto adjacent the upper edge of said side panel but spaced therefrom to define a narrow width slot parallel with the plane of said side panel and having an opening at its upper end, and adapted to receive and frictionally grip one of said bent-over flaps on said top panel, and at least two of said side panels are provided each with a rail
  • a collapsable container as claimed in claim 1 wherein each free edge of both the bottom and top panels ⁇ re held to an adjacent side panel by a bendable flap.
  • each resilient bendable flap is a metal strip having a longitudinally extending corrugation, the side of the strip on one side of the corrugation being secured to a panel and the corrugation being disposed so as to provide a rounded corner where the other side of the strip is inserted in a slot.
  • each member which cooperates with a panel to define a slot is a stiff rail which has one edge which forms one side of the mouth of the slot and which is secured to the panel along all its edges except that edge which defines the said mouth.
  • each member which cooperates with an panel to define a slot is a stiff rail having end and two longitudinal edges of which one longitudinal edge forms one side of the mouth of the slot, and is secured to the panel along the oppositely disposed longitudinal edge and along its end edges, the said end edges being each spaced from the said panel by a member which connects a vertical edge of the panel to the vertical edge of an adjacent panel whereby the rail is placed in tension.
  • a collapsable container as claimed in claim 1 in which said bendable strips are connected to the outer surfaces of the side panels at the vertical edges thereof to interconnect the said panels, and said bendable metal flaps are also connected to the outer surfaces of the top and bottom panels.
  • a collapsable container having flat front, rear and end panels, of rigid self-supporting material, each having vertical edges connected to the adjacent vertical edges of next adjacent panels by bendable strips fixed to the outer surfaces of the panels, a bottom panel having one edge portion connected to the lower edge portion of one of said front and rear panels by a bendable strip fixed to the outer surface of the bottom panel, a top panel having one edge portion connected to the upper edge portion of one of said front and rear panels by a bendable strip fixed to the outer surface of the top panel, resilient bendable flaps connected to the outer surface of at least one free-edge portion of said bottom panel, resilient bendable flaps each fixed to the outer surface of at least one freeedge portion of the top panel, and rails each having end and two longitudinal edges which are fixed at the end edges and one longitudinal edge to the outer surfaces of one of the front, rear and end panels to define a slot, having its mouth at the other longitudinal edge of said rail, for the reception of one of said bendable flaps on the top and bottom panels, the said end edges of said rails being each
