Definitions

  • This invention relates to a ready-to-use box which is provided with a tubular corner support structure at the corners for improving stackability.
  • a ready-to-use box is a box which, by virtue of a specific corner connection, permits the upright walls thereof, while mutually connected, to be collapsed onto the bottom of the box, so that the finished box can be stored without occupying much space.
  • set-up boxes which can likewise be formed from a blank but require a number of operations to be performed for making them ready for use, such as the separate erection of the sidewalls and effecting corner connections through stapling, glueing, by slipping locking tabs into receiving openings, or other operations which consume time that is often not available when vegetables or fruit are being packaged directly after harvesting.
  • GB-A-2,196,608 describes a ready-to-use box where, in the corner zones, corner support tubes have been formed from flaps provided with parallel fold lines, these flaps being situated between the collapsed walls and the bottom of the box in the collapsed condition of the box.
  • the corner support tubes In the erected box, the corner support tubes have the form of quadrilateral prisms, two of the sides thereof being in abutment with the upright walls of the box that meet in the corner in question and the two other sides reaching into the interior of the box.
  • a drawback of such prismatic corner supports with a sharp edge or rib projecting into the interior of the box is that they reduce the useful interior space of the box and are unacceptable for certain products, such as soft fruit, on account of the associated risk of damage to the products.
  • the corner support tubes extending into the interior of the box would have to be manually formed into tubes with a concave profile facing the interior of the box, i.e., the inwardly directed sharp edge of the prismatic tubular leg is bent further into the direction of the box corner in question, which has as a supplementary advantage that the support leg and the box as a whole acquire more robustness, more specifically, the torsional stiffness and the stability of the box upon dynamic loading are increased by virtue of the corner zones of the box being subject to tension.
  • This situation is shown in Fig. 4 of GB-A-2,196,608.
  • the object of the invention is to provide a box of the subject type which maintains the advantages of the tubular corner support structures in a ready-to-use box, but does not have the drawbacks mentioned.
  • a ready-to-use box that can be made from a blank by folding and adhesion, comprising a bottom surface and upright longitudinal and transverse walls connected to the bottom surface by four fold lines bounding said bottom surface, whilst at the corners where upright walls meet, one of the upright walls is provided with a connecting flap connected to the upright wall by a fold line, and the other upright wall comprises a triangular connection zone bounded by a fold line starting from the bottom corner point at a 45° angle, which connection zone, after being folded back, as viewed from the interior of the box, against the outside of that upright wall, is attached by adhesion to the outside of the connecting flap, whilst collapsible tubular corner support structures are formed from corner support flaps provided with fold lines, these corner support flaps being connected to an upright wall part of the box, is characterized in that each tubular corner support structure comprises a corner support panel which, in the erected condition of the box, extends from a first upright box wall to the corresponding corner and terminates at a distance
  • a substantially flat tube in each corner zone a substantially flat tube can be formed, having a generally L-shaped cross-section as seen in top plan view of the erected box, this tube being bounded on the outside by portions of the upright box walls meeting in that corner zone and on the inside by the first and the second corner support panels, the third corner support panel increasing the stability of the inner boundary of the L tube.
  • the stability of the corner support structure can be improved by folding a fourth corner support panel, which is connected to the third corner support panel by a fold line, back over the third corner support panel, the fold line being situated near the fold line between the first and the second corner support panel.
  • the part of the corner support structure that serves as a bearing for a superjacent box in a stack is thus enhanced and stiffened.
  • the fourth corner support panel connected to the third corner support panel by a fold line, may be connected with the second corner support panel, such that the fold line between the third and the fourth corner support panels is situated near the fold line between the first and the second corner support panels in the collapsed position of the box.
  • the corner support structure in the erected condition of the box, will comprise, in addition to the tube of L-shaped cross-section, a second flat tube, which, on the side of the interior of the box, is bounded by the third corner support panel and which overlaps one of the legs of the L-shaped tube.
  • the box comprises a bottom surface 1 and upright sidewalls 2 and 3, connected to the bottom surface by fold lines 4 and 5, respectively.
  • one of the upright walls 2 is provided with a connecting flap 7 connected thereto by a fold line 6, and in the other upright wall 3 a triangular connection zone 9 is bounded by a fold line 8 starting from the bottom corner point at a 45° angle, which connection zone, after being folded back against the outside (as viewed from the interior of the box) of the upright wall 3, is attached through adhesion to the outside of the connecting flap 7 referred to. Since this form of corner connection is generally known in ready-to-use boxes, the folding mechanism thus achieved will not be discussed in detail. It is only mentioned that this mechanism makes it possible to collapse the two upright walls over the bottom surface, the connecting flap 7 and the connection zone 9 connected thereto being locked between the two collapsed walls 2 and 3.
  • a composite corner support panel 10 is connected to the upright wall 2 through the free edge thereof (i.e., the edge located opposite the fold line 4) via a fold line 11 of limited length.
  • the corner support panel 10 is made up of a plurality of corner support panels 10a-10f interconnected by fold lines 12a-12e.
  • corner supports with a flat tubular structure can be obtained in two ways, to be explained hereinafter with reference to Figs. 2-3 and Fig. 4, respectively.
  • the composite corner support panel 10 is folded about the fold line 11 over the inside of the upright wall 2.
  • the corner support panel 10a is fixed by means of a locking tab G and a locking slot S provided for that purpose in the bottom surface 1, in a position wherein this panel 10a abuts against the inside of the connecting flap 7 and such that the corner support panels 10b and 10c are spaced from the corner rib (fold line 6).
  • a substantially L-shaped tubular space LK is present, which is part of the corner support structure.
  • the free upper edges of the corner support panels 10b and 10c form bearings for a superjacent box in a stack.
  • the panel 10e extends in the direction of the fold line 12b between the corner support panels 10b and 10c and the panel 10f is arranged against the panel 10b and attached thereto.
  • a second flat tubular space PK is formed, which overlaps one of the legs of the L-shaped tubular space LK, so that the corner support structure is enhanced and additionally stabilized.
  • the connecting flaps 7 and the adjacent parts 10a of the composite corner support panels 10 are provided with corresponding fold lines 15, 15'. These fold lines 15, 15' facilitate the corner zones being pulled open, as appears from Fig. 3A.
  • the embodiment shown in Fig. 4 only differs from the embodiment shown in Figs. 2 and 3 in that the corner support panels 10e and 10f extend in different ways.
  • the panel 10e is arranged along the corner support panels 10c and 10d and the panel 10f is folded back about the fold line 12e over the panel 10e.
  • the flat tubular space PK is no longer present and instead, a stablilization is obtained by doubling of the material (triplication), albeit with a smaller bearing for superjacent boxes in a stack. Otherwise, both embodiments can be realized starting from the same blank shown in Fig. 1.
  • Figs. 1-4 show centering tabs 13, 14 designated at the connecting flap 7 and the panel 10a, respectively. In the erected position of the box, they project above the level of the box opening. In the bottom of the box centering openings C are present, such that in a stack of boxes the centering tabs 13, 14 reach into the centering openings C of a superjacent box.
  • the present invention makes use of the corner support panels 10 extending on the inside of each box corner and is based on the insight that by providing centering tabs 14' on corner support panels 10e, 10f and forming corresponding centering slots C' in the bottom 1, spaced from the corner rib 6, the above-mentioned drawbacks of the known centering and stabilizing means are avoided and a box can be placed on a stack by placing it approximately on the topmost box of the stack and subsequently centering it by shifting action, the centering tabs 14' of the subjacent box being automatically received in the centering slots C' of the superjacent box.
  • Fig. 1 the centering tabs 14' and the centering slots C' are indicated as an alternative by means of dotted lines and Fig. 5 shows such a box in erected position.
