Definitions

  • a collapsible carton containing inner and outer telescoping shells which when constructed define a carton having four double walls of equal height, two end walls and two side walls wider than the end walls, at least one of the side walls having a hand opening on one of its inner panels.
  • This invention is directed to a construction for a double walled box collapsibly formed from a single blank of foldable sheet material such as solid or corrugated paperboard.
  • a blank formed from a single piece of corrugated or solid paperboard.
  • the blank has four upper panels joined by fold lines, an equal number of intermediate joining panels, and an equal number of bottom panels joined by fold lines.
  • the upper panels form the four walls of the inner box, the intermediate panels form the bottom of the box and the four bottom panels form the walls of the outer box.
  • the blank is erectable to form a double walled box construction having joined panels forming the inner shell within those forming the outer shell.
  • the four double walls of the box consist of two double end walls and two double side walls.
  • the side walls are wider than the end walls.
  • collapsible boxes are unexpectedly more readily disassembled if a hand Opening is provided in the inner panel of one of the side walls.
  • the box of this invention is more readily disassembled by a single operator by grasping the hand opening of the inner panel of one side Wall with one hand and the adjacent, outer panel with the other hand, whereupon the inner panels are readily pulled outwardly and the box is consequently disassembled by telescoping the inner and outer box panels.
  • My present invention is particularly suitable as embodied in collapsible boxes described in my Patent 3,278,108.
  • at least one set of panels forms sides of Patented Mar. 4, 1969 a truncated pyramid; that is, the fold lines and sides of each set are taken along lines which, if extended, would meet at a finite point.
  • the inner and outer shells are tapered. This permits the outer shell to accommodate the thickness of the walls of inner shell in so precise a manner that squeezing and crushing may be eliminated.
  • the inner shell telescopes with the outer shell so that there is little or no resistance to such collapsing, when the user wishes to pull out the inner box by means of its side wall hand opening to collapse the structure for storage.
  • the inner shell which comprises the inner panels
  • the outer shell which is defined by the outer panels
  • the central panels to fold over and form a double walled box with a double bottom. It is possible to squeeze the inner box into the outer box because even though the walls are upright the corrugated board of which the box is made is about air, having only of an inch of actual paper in said corrugated board.
  • the inner box is constructed at the corners and the air crushed out so that the outer box can be forced over the inner box as a tight fit.
  • those panels forming the inner box are the same dimensions as those forming the outer box and the thickness of paper of the box is not accounted for.
  • Considerable elfort is required to force the cardboard to compress enough to permit the inner shell to telescope within the outer shell.
  • the erected box is difiicult to collapse back to its flat form.
  • FIGURE 1 is a top plan view showing the blank pattern of the preferred embodiment of the present invention.
  • the angular relationships of the blanks are exaggerated in the drawings for clarity in the description.
  • FIGURES 2-7 show the erection of the preferred embodiment of the box utilizing the blank of FIGURE 1.
  • FIGURE 2 is a perspective view showing the blank of FIGURE 1 as preassembled and folded flat for shipment.
  • FIGURE 3 is a perspective view showing the first step in erection of the box and indicating the pyramidal shape of the box sections.
  • FIGURE 4 is a cross-sectional view taken along the line 44 of FIGURE 3.
  • FIGURE 5 is a cross-sectional view taken along the line 55 of FIGURE 3.
  • FIGURE 6 is a cross-sectional view of the box after its erection, corresponding to FIGURE 4.
  • FIGURE 7 is a cross-sectional view of the box after its erection, corresponding to FIGURE 5.
  • Such carton is formed of a single blank of foldable sheet matrial such as corrugated solid paperboard, which is scored and cut as indicated in FIGURE 1.
  • Substantially parallel to the top long edge 2 is a series of transverse score lines 3.
  • These lines in conjunction with the longitudinal score lines 4a, 4b and 4c, define a series of four substantially rectangular sections or panels 5, 6, 7 and 8.
  • End panels 6 and 8 are equal in size to each other; side panels 5 and 7 are also equal in size to each other, but are substantially wider than end panels 6 and 8.
  • side panel 7 has an opening 9 to form a hand opening, the opening being located approximately midway between the end panels 6, 8.
  • End panels 6 and 8 in the preferred embodiment of FIGURE 1, also have hand openings 10a and 10b. These panels 5, 6, 7 and 8 are at the top of the blank and form the four sides of an inner tubular shell.
  • a series of transverse score lines 12 are parallel to the bottom edge 11 of the blank. Score lines 12, in conjunction with longitudinal score lines 13a, 13b and 13c, define a second series of panels 14, 15, 16 and 17 with panel 17 having a hinged attachment flap 32 on the outer end 13 thereof.
  • the longitudinal score lines 4a and 13a lie along common imaginary line 40a.
  • lines 4b and 13b lie along line 40b
  • lines 4c and 130 lie along line 40c.
  • Side panels 14 and 16 are substantially wider than end panels 15 and 17.
  • side panels 14 and 16 and the end panels 15 and 17 of the outer shell are wider, respectively, than the side panels 5 and 7 and the end panels 6 and 8 of the inner shell.
  • End panels 15 and 17, in the preferred embodiment of FIGURE 1 have hand openings 18a and 18b.
  • These panels 14-17 form the four sides of the outer tubular shell.
  • the shell formed from the inner panels 5-8 is capable of fitting within the shell formed from the outer panels 14-17.
  • One connecting strip or portion consists of the sections 20 and 21 which are hinged along the center fold line 22.
  • the sections 20 and 21 are trapezoidal in shape, the long base of the trapezoid 20 coinciding with the long bottom edge of the panel 5, and the long base of the trapezoid 21 coinciding with the long bottom edge of the panel 11.
  • a similar set of sections 23 and 24 are formed between the panels 7 and 16, the sections 23 and 24 being hinged along the center fold line 25.
  • the connecting strip between the panels 6 and '15 is substantially rectangular and consists of the sections 26 and 27 which are hinged centrally at 28.
  • a similar strip, consisting of the sections 29 and 30 hinged centrally together at 31, is positioned between the panels 10 and 17.
  • Recesses 34a and 34b, cut into the fold lines 28 and 31, respectively, perform the function of interlocking the various panels 20, 21 and 23, 24 with panels 27, 26 and 23, 24 to form the bottom, as described below.
  • the panels 5-8 are rendered smaller than the corresponding panels 14-17 by laying out the blank with its fold lines 4a, 4b and 4c and 13a, 13b and 13c along lines 40a, 40b, 400.
  • the lines 40a-40e meet at a distant finite vanishing point (not shown).
  • the blank is laid out as an arcuate segment with a long radius. In a common size of the erected box, namely, one about a cubic foot in volume, the vanishing point or radius is fixed at feet distant.
  • This slight taper is greatly exaggerated in the drawing of FIGURE 1, and in the other figures, for clarity. It is this slight taper which allows the inner panels 5-8 to be smaller than panels 14-17.
  • the convergence of the lines 4a-4e and 13a-13e is shown, again exaggerated, in FIGURE 3, showing the box when opened, but before it is fully erected.
  • the blank After the blank has been scored and cut in the factory, as indicated in FIGURE 1, it is folded upon itself along the lines 12, and is then folded transversely along the lines 4a-4c and 13a-13c.
  • the hinged attachment flap 32 (on the end of panel 17) is brought into overlapping engagement with the free edge of the panel 14. This flap is then secured to this free edge by gluing, stapling, etc., and the resultant structure assumes the flattened condition shown in FIGURE 2.
  • a similar flap may be used to fasten the free edges of the inner shell, if even a stronger carton is desired. This completes the manufacturing procedure, which is relatively simple and inexpensive. In its flat condition shown in FIGURE 2, the carton may be stacked with others, packaged, readily transported, and stored.
  • FIGURES 2-7 The process of setting up the box by the user is illustrated in FIGURES 2-7.
  • the first step is to open the assembled blank into the position shown in FIGURE 3, in which each shell assumes a tubular configuration having a rectangular cross section.
  • the outer shell consists of the panels 14-17, its lower edge being defined by the lines 12.
  • the inner shell consists of the panels 5-10, its lower edge being defined by the lines 3. Connecting these edges are the strips which, in FIGURES 2 and 3, lie adjacent to the respective panels which they unite.
  • the final step is setting up the structure as illustrated in FIGURES 4 and 5 and consists in telescoping the inner shell into the outer shell.
  • each trapezoidal strip 20 and 21 and 23 and 24 doubles inwardly upon itself.
  • the rectangular strips of sections 26- 27 and 29-30 slide into positions between the folded halves of the adjacent trapezoidal strips and are overlapped.
  • the four folded trapezoidal strips lie in the interengaged relation shown in FIGURES 6 and 7. In this position the sections connecting the outer and inner shells form the floor in the container and provide the floor with a double layer of corrugated board.
  • the cut-out recesses 34a and 34b along fold lines 28 and 31 accommodate the edges 33 of the inwardly folding panel sections 20, 21, 23 and 24, as is shown in FIGURE 4. Theses panel sections thus interlock with panel sections 26, 27, 29 and 30 to form an interlocked double bottom.
  • Hand opening 9 is of course through inner panel 7, the inner panel 7 being on the side opposite the joint formed by the attachment flap 32 and the panel 14. In order to so locate the hand opening 9, the opening is placed through the inner panel 7 which is remote from the longitudinal end of the blank as is illustrated in FIGURE 1. Since there is no attachment flap for the inner shell, the hand opening 9 is on the side opposite the loose inner panel '5.
  • Each pair of registering end openings affords a hand grip with which the carton may be grasped for lifting or transporting, while the opening on the inner panel of one side affords means by which the carton may be readily disassembled in accordance with this invention.
  • the carton is collapsed by the reverse procedure of that shown in FIGURES 2-7. Opening 9 is grasped by one hand while the other hand applies force to the upper edge of panel 16, and the inner shell is lifted out of the outer shell (FIGS. 6,4). Finally, the opened carton (FIG. 3) is folded flat to the position shown in FIG- URE 2.
  • the outer shell tapers outwardly and the inner shell tapers inwardly. There is no tight contact between the shells (FIGS. 4 and 5) until the inner shell is telescoped wholly within the outer shell (FIGS. 6 and 7). With the provision of hand opening 9, moreover, the carton is easy to erect and disassemble.
  • the clearance between the unitary inner and outer shells permits erection and knock-down of the boxes, without the forceful effort required to telescope, with consequent crushing, identically sized box sections.
  • the side hand opening greatly facilitates disassembly by a single person. The resultant ease of assembly and disassembly permits the boxes to be repeatedly set up without strain on the cardboard.
  • the box is 12 inches wide (the width of end panels 15 and 17), 15 inches deep (the width of side panels 14 and 16) and 10 inches high (the height of panels 1447). Due to the precise measurements made possible in the preferred embodiment by the truncated pyramid shape of the blank and the definite thickness of the corrugated board (which ranges from A3 of an inch for B flute, to A of an ich for A flute) the box can *be so closely planned that the inner walls of the box may slide with ease into the outer walls of the box without crushing. The collapsing for reuse of this box having a hand opening on a side panel of the inner shell is easily achieved by one person.
  • the easy collapsing of the box embodying this invention makes new and more practical uses for the box, for example, as a factory tote box for transporting small parts from one department to another, and storing them. After the parts are removed from the box, the boxes may be collapsed and folded flat into a comparatively small package for transport back for another load of parts.
  • nested inner and outer tubular shells each of which comprises adjacent end and side panels with longitudinal hinge connections, said shells being axially movable into a telescoped overlying relationship in which the telescoped shells define a set of double walled carton sides, and a series of foldable panels transversely hingedly connected between the adjacent end edges of said shells, said foldable panels being adapted to interlock in a common transverse plane to define the floor of the carton when said shells are telescoped, said end and side panels of each shell being of substantially equal height, said side panels of each shell being of substantially equal length, said end panels of each shell being of substantially equal length, all of said side panels being substantially longer than any of said end panels, at least one side panel of said inner shell having a hand opening located substantially midway between said end panels, said hand opening extending through said inner shell only.
  • a single piece blank of paperboard for a double walled carton comprising four inner shell panels consisting of two side panels and two end panels and lying along one transverse edge of the blank and defined by longitudinal score lines, four outer shell panels consisting correspondingly of two side panels and two end panels and lying along the opposite transverse edge of the blank and defined by longitudinal score lines, and four separated bottom forming panels extending between said inner and outer shell panels and defined therefrom by transverse score lines, at least one of the inner shell side panels only having a hand opening substantially midway between the ends thereof, said hand opening extending through said inner shell only.
  • the collapsible carton of claim 1 including an attachment flap transversely hingedly attached to one of the panels of the outer shell, the flap being fixedly attached to an adjacent panel to form a continuous, bonded outer shell, said hand opening extending through the side panel of the inner shell which is opposite the side panel of the outer shell to which the flap is attached.
  • a single piece blank of paperboard for a double walled carton comprising:
  • outer shell panels consisting correspondingly of two side panels and two end panels and an attachment flap, the side and end panels lying along the opposite edge of the blank and defined by longitudinal score lines, the flap lying along one transverse edge of the blank and being attached to one of the outer shell panels, and
