  • DETAILED DESCRIPTION OF THE INVENTION
  • With respect to the drawings, a blank 10 of clear or translucent plastic is shown in collapsed, unassembled form in FIG. 1. A front panel 11 has a finger hole 12 and is further defined by a score line 13 and a pair of spaced elongate score lines 17. A flap panel 4 is defined by score or fold line 13 and a tapered side portion 15 and a straight edge portion 16 and is used to reinforce the bottom of the assembled container or vertical file 53 (FIGS. 5-8).
  • A first side panel has straight edge portion 19, a slanted edge portion 20, another edge portion 21 and two elongate score or fold lines 22 and 33. A first rear panel 23 is defined by score line 22 and edge portions 24, 25 and 26. The first rear panel 23 includes three spaced vertical slots 27 each having spaced ends in the form of top and bottom end portions 28, 29.
  • A first bottom portion 30 is defined by an elongate score or fold line 33 and two slanted edge portions 31 and three rectangular securing tabs 32. Two spaced securing slots 34 are formed in the bottom portion 30 adjacent score line 33.
  • A second side panel 35 is substantially identical to panel 18 and includes edge portions 36, 37 and 38 and elongate score or fold lines 39 and 43. A second bottom panel 42 is also defined by elongate score or fold line 43 and includes a straight edge portion 46 and three spaced securing tab slots 44 and two spaced slots 45 closely adjacent score line 43.
  • A second rear panel 40 includes an elongate score or fold line 39 as one edge portion and an upper edge portion 50 and a lower score or fold line 47′ connecting to base panel 47. Panel 40 includes three spaced locking tabs 41 connected via spaced score or fold lines 41′. Flap panel 47 is substantially identical to panel 14 and has straight edge portion 49 and tapered edge portion 48 and is also used to reinforce the bottom of an assembled container 53.
  • FIG. 1 illustrates the inside surfaces of the blank 10 but it is to be understood that the specific construction of the blank 10 depends on which side the various score or fold lines used for foldable connections to facilitate bending panels and tabs in a specific direction with respect to the other portions of the blank 10.
  • The assembly of the blank 10 proceeds as follows. Panel 14 is folded towards the assembly along score line 13 to place it at a right angle to front panel 11.
  • Flap panel 47 is folded in a similar manner around score line 47′ with respect to panel 40. Panels 30 and 42 are also folded at right angles along respective score lines 33 and 43.
  • Side panel 40 is folded along score line 39 to place flap panel 47 above folded panel 42. Panel 14 is also positioned above panel 42 when side panel 35 is folded toward the user along score line 17.
  • Panel 30 is folded 90° along score line 33 to bring panel 30 below panel 42 and each tab 32 is inserted into respective tab slot 44. After this step panels 14 and 47 should be disposed over panel 42, which overlies panel 30.
  • Panel 23 is folded towards the user along score line 22 and each locking tab 41 is bent at a right angle along corresponding score line 41′ and inserted into respective locking slot 27 to position panel 40 outside panel 23.
  • FIG. 2 illustrates a top partial detail showing the folding of panel 40 and at right angle to place a folded locking tab 41 into a locking slot 27. The securing step is shown completed in FIG. 3.
  • FIG. 4 illustrates a rear view of a locking tab 41 being moved towards a locking slot 27. The locking tab 41 includes a pair of spaced arcuate notches 51 to greatly inhibit the withdrawal of the tabs 41 once inserted into locking slots 27. The procedure for securing a locking tab 41 into a locking slot 27 involves forcing the lower end of a tab 41 into a slot 27 near a lower end portion 29 and then pushing the upper portion of a tab 41 into the slot 27 adjacent the upper end portion 28. Preferably, three locking tabs 41 are used and are preferably installed from the lower tab 41/slot 27 pair and then the middle pair and finally the uppermost pair.
  • FIG. 6 illustrates the assembled lower panels 30 and 42 connected together by forcing a respective securing tab 32 into a corresponding securing slot 44. There are preferably three spaced tab 32/slot 44 pairs as clearly shown.
  • FIGS. 5-7 illustrate respective front, bottom and rear views of an assembled container 53 for use as a vertical file. FIG. 8 illustrates a perspective view of the container 53. Slots 34, 45 are formed to provide feet 34′, 45′ to elevate the bottom of the container slightly to compensate for the increased thickness resulting from the use of flap panels 14 and 47.
  • The blank 10 is preferably shipped and sold in a partially assembled form by inserting tabs 41 into slots 27 and leaving the bottom panels 30, 42 and flap panels 14, 47 flat and then folding the blank 10 to place the inside surface of front panel 11 against a portion of side panel 18 and to place rear panel 40 against a portion of side panel 35.
  • With respect to FIGS. 9 and 10, a container in the form of a cover for the container or vertical file 53 of FIGS. 1-8 is shown at 54. Side walls 55 and 56 connect end panels 59 and 85 to define interior space 57. End panel 84 is formed from overlapping panels 58 and 75.
  • Container or cover blank 54 is constructed in a manner substantially similar to that of the blank 10 used to form the assembled container 53 and, with the exception of slots 45 and feet 45′, is constructed in a similar manner.
  • Fold lines 62 and 63 separate bottom panels 72 and 84. Tabs 71 fit into slots 65, tabs 67 and 79 are positioned inside and rest above the assembled wall formed by overlapping panels 72, 84. Tabs 83 fit into slots 77 to secure overlapping panels 75, 85 to form wall 86 defined along score lines 77′ and 83′.
  • Container or cover 54 is sized to fit snugly over the upper portion of container or vertical file 53.
  • It is to be understood that terms such as “front” and “rear” are used as a manner of convenience since the finger hole 12 of container 53 usually faces outwardly toward a user when the container is placed on a shelf adjacent a rear wall of a house or a rear wall of a bookcase or the like.
  • While the invention has been described with respect to certain specific embodiments, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention. It is intended therefore, by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention.
