1. Field of the Invention
The present invention relates to reclosable containers for articles such as photographs, film strips, and compact discs, and particularly to containers formed from a unitary flat blank of flexible plastic.
2. Related Art
A wide variety of reclosable containers exist, some of which are formed from flat plastic blanks, what is desired is a reclosable container formed of a flat blank to provide a sturdy container that is easier to use than prior art devices.
For example, U.S. Pat. No. 6,401,917 discloses a container formed of a unitary plastic blank. The container therein uses a pair of relatively short locking tabs that are inserted in a respective pair of slits formed in a lower portion of the front flaps to secure the flaps inside the front panel.
The present invention provides elongated tabs formed on the sides of the rear panel and elongated slots are formed in the flaps foldably connected to the front panel. This approach provides a more secure connection because the tab/slot combinations extend substantially the length of the sides of the respective panels and flaps.
In addition, the present invention places the flaps flat against the inner surface of the rear panel. The prior art container has flaps that are forwardly mounted and extend upwardly past the upper edge of the front panel and thus interfere with usage of the container. The present invention employs a large cutout in the front panel to facilitate the use of the container.
In one aspect of the present invention, there is provided a flat blank for forming a collapsible and reclosable container for articles comprising: a rear panel having upper and lower portions and a pair of spaced side portions; a top panel having front and rear portions foldably connected to the upper portion of the rear and adapted to be bent at a right angle to the rear panel; a cover member having upper and lower portions foldably connected to the front portion of the top panel and adapted to be folded downwardly to a closed portion; a bottom panel having a rear and front portion foldably connected to the lower portion of the rear panel and adapted to be bent at a right angle to the rear panel; a front panel having side portions, a lower and upper portion foldably connected to the front portion of the bottom panel and adapted to be folded upwardly to be substantially parallel to the rear panel; a pair of spaced side panels each having side portions, each foldably connected to a respective side portion of the front portion and adapted to be bent to a right angle to the front panel; a pair of flaps each foldably connected to one respective side portion of a corresponding side panel and adapted to be bent at a right angle to the side panel; a pair of locking tabs each having ends and each foldably connected to a respective said side portion of the rear portion and adapted to be bent at a right angle to the rear panel; each side panel including a locking slot for receiving a respective locking tab to secure the front panel substantially parallel to the rear panel to define an interior space when the blank is folded to form a container.

The novel features which are believed to be characteristic of this invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings, in which:
With respect now to the drawings, the preferred flat, unitary, translucent plastic blank used to form the container is shown at 10. A tapered cover panel 11 is defined by a rear side defined by fold line 12, two side edge portions 14 and a tapered front edge portion 15. A securing tab 16 is cut into cover 11. Additional fold lines 13 and 13′ connect top panel 17 to rear panel 18 which includes a tab 19 formed by cut 20 that first through the center of one or more CD's, DVD's 41, etc. to hold them vertically. The side edge portions 21 of rear panel 18 are defined by fold lines 22. Locking tabs 23, having arcuate notches 24 at the ends thereof are foldably connected via fold lines 22.
A bottom panel 26, defined by fold lines 25 and 27, is foldably connected to front panel 28. Panel 28 includes two side edge portions defined by fold lines 30 and two side panels 32 defined by fold lines 31. Arcuate securing slot 29 is used to secure cover panel 11 via locking tab 16.
A pair of front flaps 33 are defined by respective sides 34 and fold lines 31. Each fold line 31 has a locking slot 37 having ends 38 into which are inserted locking tabs 23. Top edges 35 and cutout portion 36 further define front panel 28.
The construction of container 39 is accomplished by folding front panel 28 upwardly at a right angle to bottom panel 26 along line 27. The front flaps 33 are folded inwardly along fold lines 30 and 31 to form side panels 32.
Locking tabs 23 are bent at right angles at lines 22 and are inserted into locking slots 37 to place front flaps 33 flat against the inside surface 18′ of rear panel 18.
Cover panel 11 is then folded over lines 12 and 13 to place securing tab 16 into securing slot 29 to hold cover 11 over front panel 28.
The positioning of flaps 33 against the inner surface 18′ of rear panel 18 keeps the flaps 33 out of the way and thus they do not interfere with access to the articles within interior space 40.
The blank 10 is shipped and sold in a collapsed form achieved by folding cover panel 11 backwards along line 13′ against the outside surface of rear panel 18. Front panel 28 folded upwardly along line 27 to place the panel 28 flat against the inside surface 18′ of rear panel 18. The locking tabs 23 are folded flat against the inside surface 18′ of panel 18. The front flaps 33 are then folded along lines 30 to locate them flat against the outside surface of front panel 28.
Locking tabs 23 extend substantially the length of the sides of the rear panel 18 and locking slots 37 similarly extend substantially the length of the sides of front panel 28. This structure provides a more sturdy container 39 than prior art approaches.
Access to the interior space 40 of the container 39 and the various articles 41 therein is facilitated by the large cutout 36 located substantially medially in front panel 28.
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.
