(Cl. 229-34) This invention generally relates to an improved and novel box construction and more specically provides a shipping container made of paper, cardboard, metallic material, plastic material or other materials feasible for the construction of containers for shipping various types of products such as those generally classied as agricultural products, machinery, furs, furniture, accessories, spare parts for various equipment and other similar articles.

An object of the present invention is to provide a box construction which is initially formed from a single blank of material which may be shipped or transported to its point of origin in a relatively small space after which the device may be folded to a set-up condition for retaining articles during shipment thereof.

Another object of the present invention is to provide a box construction which is extremely strong and uses a minimum of materials and easy to manufacture and assemble at shipping and packing points without use of stapling, gluing or the use of other fastening means.

A further object of the present invention is to provide a box construction which may be used repeatedly and employed for easy display of merchandise and which is relatively inexpensive to manufacture.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a plan view of the blank of the box construction of the present invention;

Figures 2-6 are enlarged perspective views of one corner of the box illustrating the successive steps in assembling the box;

Figure 7 is a perspective view of a completed box in accordance with the present invention;

Figure 8 is a perspective view illustrating a plurality of stacked boxes illustrating the method of stacking;

Figure 9 is a plan view of the box with the top being removed illustrating the partitions therein;

Figure l is a partial plan View of the other form of the box; i

Figure ll is a partial perspective view of the corner of the modified form` of the box illustrating the assembly thereof; and l Figure 12` is a detail sectional View illustrating the side panel construction of the modified form of the box.

Referring now specifically to Figure l of the official drawings, the numeral `generally designates the blank of unitary construction from which the box of the present invention is formed. `The blank 10 when lin unassembled condition is of planar construction and may be disposed in `stacked relation` for shipment to a packaging or shipping point in a relatively small space.

The blank 10 includes` a bottom forming panel 12,

side forming panels

14 and 16 formed integrally with blank of an- 2,843,307 Patented July 151958 the opposite edges of the bottom forming panel 12. Formed integrally with the outer edges of the

side forming panels

14 and 16 are

top flaps

18 and 20 which are each provided with

partition flaps

22 and 24 on the outer edges thereof. All of the panels and llaps 12-24 are of substantial equal length and are integrally formed and attached to each other by fold lines 26 all of which are of substantially identical construction. The

side panels

14 and 16 are equal so that the

top iiaps

18 and 20 will overlie the bottom panel 12 in spaced parallel relation and each of the

flaps

18 and 20 is generally one-half of the area of the bottom panel 12 wherein the

top flaps

18 and 20 will cover the bottom panel 12. The

partition flaps

22 and 24 are equal in length to the

side panels

14 and 16 for positioning in depending relation to the

top flaps

18 and 20 in parallel relation to the side panels 14 and 16V for engagement with the bottom panel 12 for dividing the area between the bottom panel 12 and the

top flaps

18 and 20 into two equal compartments. Each of the

top flaps

22 and 24 is provided with a recessed portion 28 in the outer edge thereof to permit easier assembly and disassembly of the

partition aps

22 and 24 and also to permit communication between the compartments formed by the

partition ilaps

22 and 24.

Formed on each end of the bottom panel 12 is an end panel generally designated by the numeral 30 which includes an inner section 32 and an outer section 34 joined together by a fold line with the inner section 32 being attached to the bottom panel 12 by a fold line similar to the fold line 26 to permit the outer section 34 to be folded inwardly into overlying relation to the inner section 32 of the end panel 30 thereby forming an end panel of double thickness.

The bottom panel 12, adjacent each edge thereof, is provided with a pair of spaced slots 36 for receiving projecting lugs 38 on the outer edge of the outer section 34 of the end panel 30 for retaining the

sections

32 and 34 in overlying relation when the end panel 30 is disposed in perpendicular relation to the bottom panel 12. Also, the end panel 30 is provided with a pair of centrally disposed elongated slots 40 and a pair of outwardly disposed short slots 42 which are disposed along the fold line between the

sections

32 and 34 which are facing upwardly to provide openings for a purpose described hereinafter when the end panels 30 are disposed in upstandiug relation to the bottom panel 12.

At each end of the end panel 30 the bottom panel 12 is provided with a laterally projecting tab 44 which is vslightly longer than the length of the end panel 30 and is provided with a projecting lug 46 on its outer edge wherein the lug 46 is adapted to be inserted into a slot 48 on the end of the

side panel

14 or 16 adjacent to the tab 44. It is noted that the tab 44 is separate from the end panel 30 and is attached to the bottom panel 12 by a short fold line wherein the tab 44 may be raised to an upstanding position perpendicular to the bottom panel 12 for positioning in the slot 48 when the

respective side panel

14 or 16 is raised to perpendicular relation to the bottom panel 12 thereby retaining the side panels in upstanding position.

Each of the

side panels

14 and 16 are provided on each end thereof with an outwardly extending tab 50 which has a recessed portion 52 on the edge` thereof re mote from the bottom panel 12 with the projecting lug 54 at the outer end of the recessed portion 52. The lug 54 is adapted to engage the outermost slot 42 in the end panel 30 when the end panel 30 is folded `over with the tab 50 being positioned therebetween.

Each ofthe

top flaps

18 and 20 are provided on each end thereof with a projecting tab 56 having an elongated projecting lug 58 on the end thereof with the lug 58 heilig` disposed adjacent the outer edge `of the

top panels

18 and 20 for reception in the elongated slots 40 from the upper edge thereof when the

top iiaps

18 and 20 are brought into overlyingV relation to the bottom panel 12. .-ReferringnowV specifically to Figures 2 6, it will be noted that the sequential steps of assembling the box from the blank is illustrated. Figure 2 illustrates the initial step wherein the top panel 18 is folded upwardly to an upstanding position after which the tab 44 is folded into an upstanding position and then lthe side panel 14 is folded into an upstanding position and the slot 48 is brought into registry with the lug 46 on the tab 44 which will retain the tab 44 in upstanding position and also retain the side panel 14 in upstanding position. The tab 50 on the side panel 14 is then folded inwardly against the outer surface of the tab 44 and the end panel 30 including the

sections

32 and 34 are folded upwardly along the old line between the end panel 30 and the bottom panel 12 against the outer surface of the tab 50 as illustrated in Figure 4. The outer section 34 of the end panel 30 is then folded inwardly and the lugs 38 are brought into registry with the slots 36 for retaining the

sections

34 and 32 in overlying relation. The lug 54 on the recessed portion is engaged in the slot 42 and the slots 40 are presented upwardly substantially as illustrated in Figure 5. The tabs 56 are then folded inwardly and the elongated lug 58 thereon is received within a slot 40 and the

partition flaps

22 and 24 are folded downwardly and are positioned in abutting engagement with each other for retaining the box in closed position. The box may be opened by lifting vertically on the

partition flaps

22 and 24 and the cut out portion 68 therein forms a handle for such opening of the box.`

Each side edge of the bottom panel 12 is provided with an elongated slot 60 adjacent the

side panels

14 and 16. Each

side panel

14 and 16 includes a small slot 62 adjacent and parallel to the slot 60 and also includes a cut-out lug 64 which is cut around three sides thereof to permit the lug 64 to be forced inwardly. Each

top flap

18 and 20 includes a cut-out lug 66 having a generally triangular-shaped free edge which is adapted to extend upwardly for insertion into a slot 60 on a container positioned thereon in stacked relation. The triangular end portion of the lug 66 is extended outwardly through the opening formed when the lug 64 is pushed inwardly after which the pointed end of the lug 66 is inserted back through the slot 62 thereby securely interlocking the containers in stacked relation substantially as illustrated in Figure 8. Each of the

top flaps

18 and 20 may also be provided with cut-outs 68 adjacent the inner edges thereof for facilitating opening of the iiaps.

As illustrated in Figure 9, a pair of liners or dividers 70 may be provided which are positioned within the container and include three complete walls with the outer side walls including recesses 72 for receiving the inwardly struck lug 64 wherein the liner may have extending projections which extend in overlying relation to the inwardly struck lug 64 wherein the lug 62 will retain the liners `or partitions 70 in position.

As illustrated in Figures lO-lZ, a modiiied form of the present invention is generally designated by the numeral 74 and is substantially identical in construction to that form of the invention illustrated in Figures 1 9. The only difference is that the end panels 30 are only provided with the short slots 42 and the tab 56' `on the top panel does not have any lug 58. In this instance, the tab 56 is inserted lbehind the inner surface of the end panel 30 when it is in assembled position as illustrated in Figure l2 and the tab 56 is equal in depth to the side panels for reinforcing and completing the end panel which is of double thickness at the lower portion thereof. Otherfthan these two changes, identical reference numerals are employed for setting forth the similar structure.

The exposed cut edges may be laminated by parafiin, or other substances, to prevent fraying of all cut edges thereby protecting the tabs 56 and the slots from becoming frayed. Ventilation openings may be provided wherever desired in any of the panels as may become necessary in adapting the box to various uses.

It will be seen that the present invention provides a box -construction which is simple to assemble and may vbe employed for many uses and may be constructed of various materials. The size, shape and arrangement of the various elements may be altered to adapt the box to its many and varied uses.

The foregoing is considered as illustrative only lof the principles of the invention. Further, since numerous modiiications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed. i
