BACKGROUND OF THE INVENTION




This present invention relates to an improvement in knock-down, collapsible, foldable boxes, and more particularly to shoe boxes for easy storage and shipment, both in the knock-down or assembled state while transporting shoes and, when set up and configured for use, are stackable upon one another and have a removable drawer-like container which, when removed, permits easy retrieval of the shoes within, especially in a shoe store, without adversely affecting the remainder of the stack. It must be understood that, though this invention was prompted by a need for better shoe boxes adapted to storage (in both shoe manufacturing and in retail stores), retrieval, and return, it is capable of being used for any product storage and is not limited to shoes and shoe boxes.




Currently shoes are shipped from manufacturer or distributor to a retailer in a pre-formed, generally pasted, shoe box. The typical box has a bottom part and a top part. The bottom part has a base or bottom with four upstanding walls which form a container. The top part is the cover which has an upper base with four downwardly extending walls which snugly fit around the four upstanding walls to cover the opening of the bottom part. Typically the four downwardly extending walls are considerably shorter in length than are the four upstanding walls. This box thus is a pasted-up open-top box closed by a removable lid adapted to fit snugly around the outside of the open-top of the box.




It is customary in shoe stores to stack such boxes on top of one another and to have numerous such stacks or columns abutting one another. In such stacking configurations, the stacks can be extremely high consisting of many boxes stacked upon one another. Stacking and columning are generally done in some organized fashion by style and size for example. Shoe boxes such as these generally have information about the shoe style, size, and color which is printed on one or more of their upstanding walls. When a shoe salesperson, for instance, needs a pair of shoes which are in a box on top of the stack, there is no problem in merely taking that box out to the showroom and returning it to the same location without disrupting the organization of the stacks. When a desired shoe is in a box or boxes below the top of a stack, in the middle, or at or near the bottom, pulling the box from the stack is more difficult. Box tops and bottoms can get damaged.




For organizational purposes, it is best that the space created by the removed box remain unfilled so that, if a sale is not consummated, the box may be returned to its proper organizational location. This is not what usually occurs however. Once a box is removed from the stack, the boxes in that stack above the removed box simply fall into the space created by the removed box. Given the configuration of the box and lid, the descent generally is not smooth and orderly thereby creating an unsightly, scattered, appearance and unsettling the organization of the stacks.




The present invention eliminates the bulk associated with shipping the pre-formed pasted boxes to the shoe manufacturer, for example, and eliminates the problems associated with removing boxes from their stacks in the retail shoe store. In addition, the present invention, with its sleeve, slidable and removable container, permits re-use of the container and placement of the container into its original or any vacant sleeve.




Accordingly, several objects and advantages of my invention are to:




a. provide boxes which are easy to manufacture and less bulky to ship to the shoe manufacturer, to the retailer, and to an end-user;




b. provide boxes for products which are stackable and maintain their stack integrity after the container portion of a box is removed from the stack;




c. provide boxes for products which facilitate retrieval of the product therefrom and return thereto;




d. provide boxes for products which are not limited to a single product size and style but which are relatively fungible and re-usable; and




e. provide product boxes which facilitate reorganization of a retailer's product inventory.




The foregoing has outlined some of the more pertinent objects of the present invention. These objects should be construed to be merely illustrative of some of the more prominent features and applications of the intended invention. Many other beneficial results can be attained by applying the disclosed invention in a different manner or by modifying the invention within the scope of the disclosure. Accordingly, other objects and a fuller understanding of the invention may be had by referring to the summary of the invention and the detailed description of the preferred embodiment in addition to the scope of the invention defined by the claims taken in conjunction with the accompanying drawings.




BRIEF SUMMARY OF THE INVENTION




The above-noted problems, among others, are overcome by the present invention. Briefly stated, the present invention contemplates a knock-down, foldable, collapsible, stackable box assembly which has a sleeve and a removable container insertable into and out of the sleeve. The container and sleeve are formed of folding blanks which, when folded and assembled, create a sturdy, slidable drawer-like box assembly with the inner container being the removable drawer. The front of the container has a compressible handle-like mechanism which, when one or more box assemblies are shipped together, especially in large shipping containers, compresses without damage to its structure or function. When not in use by the retail purchaser or end-user, the sleeve may be unfolded and collapsed flat and the container may be unfolded and unassembled into a flat blank. When needed, each is easily re-folded, re-assembled into useable box, drawer-like structures. Any suitable materials may be used for the box assembly but a cardboard or cardboard-like materials are best.




The foregoing has outlined the more pertinent and important features of the present invention in order that the detailed description of the invention that follows may be better understood so the present contributions to the art may be more fully appreciated. Additional features of the present invention will be described hereinafter which form the subject of the claims. It should be appreciated by those skilled in the art that the conception and the disclosed specific embodiment may be readily utilized as a basis for modifying or designing other structures and methods for carrying out the same purposes of the present invention. It also should be realized by those skilled in the art that such equivalent constructions and methods do not depart from the spirit and scope of the inventions as set forth in the appended claims.

′ and a rear receiving slot


38


′. A front-end assembly


19


extends forward and outward from the bottom


23


which, when the front-end assemble


19


is folded and assembled, forms the front


22


of the container


20


and also forms a compressible handle mechanism therefor. As shown here, the front-end assembly


19


has a first front panel


11


which is foldably connected to the bottom


23


front, followed by a second front panel


12


which is foldably connected to the first front panel


11


, followed by a third front panel


13


which is foldably connected to the second front panel


12


, followed by a fourth front panel


14


which is foldably connected to the third front panel


13


, followed by the fifth front panel


16


which is foldably connected to the fourth front panel


14


. At least four such front panels are required for this container but a fifth, or more, front panels may be so connected. The main purpose of the fifth front panel

,


17


to the third front panel


13


. The first, second, and third front panels


11


,


12


,


13


, in conjunction with the extension flaps


15


,


17


will, when the front-end assembly


19


is folded and assembled, form a handle or grabbing mechanism to facilitate the translation of the container


20


in and out of the sleeve


70


and will also provide sound structural support for the front of the container


20


.




A rear-end assembly


39


extends rear ward and outward from the bottom


23


which, when the rear-end assembly


39


is folded and assembled, forms the completed, structurally sound, rear


24


of the container

28


which is foldably connected to the first rear panel


27


, followed by a third rear panel


29


which is foldably connected to the second rear panel


28


. At least two such rear panels are required for this container


20


but a third, or more, rear panels may be so connected. The main purpose of the third rear panel


29


will be explained as the assembly of the container


20


is more fully described. Adjacent to the far end of the second rear panel


28


, at or near the fold-line of the second and third rear panels, is a rear tab


38


which, when the container


20


is assembled, will securingly mate with receiving slot


38


′.




A first-side assembly


43


and a second-side assembly


53


are foldably connected to opposing sides of the bottom


23


of the container


20


. For reference purposes, these respectively form a right side and a left side for the container


20


. Each side assembly


43


,


53


has a front-side lockable flap


35


,


37


, respectively, and a rear-side lockable flap


25


,


26


, respectively. The right front-side lockable flap


35


has an extension tab


45


and a slit


47


which, when folded and assembled, securely mate with the extension tab


46


and slit


48


of the left front-side lockable flap


37


. Similarly, the right rear-side lockable flap


25


has an extension tab


65


and a slit


67


which, when folded and assembled, securely mate with the extension tab


66


and slit


68


of the left rear-side lockable flap


26


. When so folded and assembled, the container


20

FIGS. 4-7

and


9


-


14


illustrate the folding and assembly of the container


20


. It is best to fold and assemble the side assemblies first; either side assembly may be folded and assembled first, either by hand or by mechanical means. In this regard, each side assembly is folded up followed by folding the front-side lockable flaps


35


,


37


in the direction of arrows A and B and mating the respective flaps as previously described and as illustrated in FIG.


5


. This is followed by folding the rear-side lockable flaps


25


,


26


in the direction of arrows A′ and B′ and mating these respective flaps similarly as the front-side flaps were mated. It must be understood that the extension tabs


45


,


46


may be exposed as illustrated in

FIG. 5

or may be tucked inward and not exposed. With either method, the side assemblies securely lock together and thereby establishes four upstanding perimeter walls of the container


20


.




Reference is now made to

FIGS. 6-11

for completion of the front-end assembly


19


. As previously discussed, the handle mechanism is formed by the first front panel


11


, the second front panel


12


, and the third front panel


13


in combination with extension flaps


15


,


17


and the expansion section in between the third front panel


13


and its extending extension flaps


15


,


17


.

FIG. 8

details the expansion section


30


between, and serving as the connection to, the third front panel


13


and its two extension flaps


15


,


17


. The expansion section


30


is an important feature of the container


20


. As illustrated here, the expansion section


30


has three fold-lines


31


,


32


,


33


. Fold-line


32


has one or more slots


34


and it, the fold-line, is folded or creased inwardly or outwardly in the direction of arrows X. Fold-line


31


is folded or creased in the direction of arrow Z and fold-line


33


is folded or creased in the direction of arrow Y. As so folded, the expansion section takes on an accordion-like appearance and function. The slots


34


facilitate it compressibility. It must be understood that there may be more than three fold-lines as illustrated and that one or more slots


34


may be inserted into any one or more of the fold-lines. Ease of construction, assembly, and use militates in favor of three fold-lines as shown with one or more slots


34


in the middle fold-line


32


.




After the folds have been made to ready the expansion sections


30


,


30


′ on both extension flaps


15


,


17


but, before the extension flaps


15


,


17


are folded, the first front panel


11


should be folded upward and inward, in the direction of arrow C followed by the downward and inward folding of the second front panel


12


in the direction of arrow D. As so folded, these front panels


11


,


12


resemble an up-side-down “V”. The third front panel


13


is then folded upward and inward, in the direction of arrow E. This is followed by the inward folding, in the direction of arrows F, of the extension flaps


15


,


17


over the first front panel


11


.

FIG. 9

represents the result of these folds.




The front-end assembly


19


is completed by folding the fourth front panel


14


and, in the direction of arrow G, carrying it over and into the container


20


to the bottom and inserting the tab


18


into the receiving slot


18


′ thereat. Although a fifth front panel


16


is not required, it is preferred in that it protects and better secures the tab


18


to receiving slot


18


′ connection. The front-end assembly


19


is now complete and sturdy. A compressible handle mechanism extends from the front end and is suitable for grabbing, holding, and moving the container into and out of the sleeve


70


.




The container


20


is completed with the folding and carrying over, in the direction of arrow H, of the rear-end assembly


39


and, similar to the assembly of the front-end assembly


19


, insertion of the tab


38


into the receiving slot


38


′. Similar to the front-end assembly


19


, the third rear panel


29


, though not necessary, is preferred as it too protects and better secures in place the rear-end assembly tab


38


to receiving slot


38


′ connection.





FIGS. 15-20

illustrate the sleeve


70


component of the box assembly


10


. The sleeve


70


is generally formed from a single flat blank with fold lines folded and the ends fastened by glue, a self-adhesive strip, or similar means to thereby form a collapsible basically rectangular hollow into which the container


20


may be insertable and removable.

FIG. 15

illustrates the sleeve


70


in its knock-down, collapsed state.

FIG. 16

illustrates the sleeve


70


, from the rear, in an uncollapsed or open state ready for assembly. The sleeve


70


has a foldable top rear flap


77


, a foldable bottom rear flap


79


and two foldable rear side flaps


75


,


76


. The top rear flap


77


has inward and upward angled sides terminating at and creating a top extension flap


97


. It also has a hole or vent


78


which facilitates the insertion and removal of the container


20


. The vent


78


is shown on the top rear flap


77


but instead may be on the bottom rear flap


79


, or on either rear side flap


75


,


76


, or any combination thereof. The bottom rear flap


79


has a depression or channel


96


centered on its outer edge and two step taps


95


extending farther outward beyond the channel


96


. Each rear side flap


75


,


76


has a protruding tab


85


,


86


and groove


87


,


88


, respectively.




Assembly of the sleeve


70


entails folding the bottom rear flap


70


upward to resemble the sleeve


70


as depicted in FIG.


17


. This is followed by the inward folding of each rear side flap


75


,


76


in the direction of arrows I and inserting the respective protruding tabs


85


,


86


over the channel


96


and into the sleeve


70


. The result of this operation is depicted in FIG.


18


. Next the top rear flap


77


is folded downward and the top extension flap


97


inserted over the channel


96


and into the sleeve


70


. As assembled, the top extension flap


97


is seated in between the bottom rear flap


79


and the protruding tabs


85


,


86


, and such configuration forms a walled rear for the sleeve


70


and a stop for the container


20


. The box assembly


10


is now ready for full use and stacking without experiencing excess damage from shipping or use.




The components (container


20


and sleeve


70


) of the box assembly


10


each come with fold or crease lines and cuts, slits, or slots as described herein already incorporated in the respective component.
