2 Claims. (Cl. 229

This is a division of application Serial No. 853,416, filed November 16, 1959, now abandoned.

The invention relates in generalto new and useful improvements in corrugated boxes and the like, and more particularly seeks to provide a compartmented corrugated box which is suitable for holding large quantitles of free flowing solids and the like, and a filling device for simultaneous filling of each of the compartments of the box.

A corrugated box may be readily reinforced against endwise collapsing by placing upright reinforcing therein. However, when a large corrugated box is filled with a free flowing solid, the outward pressure of the solids on the walls of the box results in the bowing of the walls notwithstanding the existence of internal reinforcement which would normally prevent endwise collapsing.

In view of the foregoing, it is an object of the invention to provide a corrugated compartment bulk box for free flowing solids and the like, the box, due to its novel construction, having a relatively great strength of the type which will increase the stacking strength of the box and minimize the outward bowing of the side walls now experienced with other styles of corrugated bulk boxes currently in use, and a filling device for simultaneous filling of each compartment of the box.

Another object of the invention is to provide a largecorrugated box to function as a bulk carrier, the corrugated box being formed in sections whereby not only is the strength of the box greatly increased, but also the individual compartments are provided so that, if desired, more than one type of bulk material may be stored within the box, and/or each individual compartment may be detached from the main body and handled 'as a separate unit.

Still another object of the invention is to provide a novel bulk carrier in the form of a corrugated box which includes a base having an upstanding peripheral flange,

a plurality of nested sleeves seated within the base and projecting upwardly thereabove, and a cover overlying thesleeves, the cover having a peripheral flange depending therefrom and being telescoped over the upper ends of the sleeves, the base and the cover forming both the ends of the sleeves and retaining the sleeves against separation, the individual sleeves being capable of preventing their side walls from'bowing due to the outward pressure of the bulk material contained therein.

A further object of the invention is to provide a corrugated box for free flowing solids, the corrugated box being provided with a plurality of compartments which are disposed adjacent a common center, and there being provided a filling device which may be seated on the upper ends of the individual compartments and which filling device will simultaneously direct streams of free flowing solids into the individual compartments so that the entire box may be filled at one time through the use of the.

filling device.

A still further object of the invention is to provide a corrugated box particularly adapted to function as a bulk carrier for free flowing solids and the like, the corrugated box being generally of the size of a conventional pallet and having feet on the underside thereof which are spaced apart suitable distances to receive the tines of a fork 3,248,037 Patented Apr. 26, 1966 inafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims, and the several views il lustrated in the accompanying drawings:

In the drawings:

FIGURE 3 is an enlarged bottom perspective View of thefilling device of FIGURE 2, and shows the specific details of the construction thereof for mounting upon the sleeves of the bulk-carrier.

FIGURE 4 is an enlarged plan view of the bulk carrier as it appears in FIGURE 1, and shows the specific relationship of the filling device with respect to the individual sleeves. I

FIGURE 5 is an enlarged vertical sectional view, taken substantially upon the plane indicated by the section line 5-5 of FIGURE 1, and showsthe specific internal construction of the bulk carrier, there also being shown the details of a strap which may be used for holding together the individual sleeves intermediate their ends.

FIGURE 6 is an enlarged exploded perspective view of the various components of the bulk carrier and shows the various details thereof.

The general details of the embodiment of the invention disclosed herein are generally illustrated in FIGURE 1, the bulk carrier being generally referred to by the numeral 10. The bulk carrier 10 is formed of a base, generally referred to by the numeral 11, a plurality of upstanding sleeves or tubes 12 seated within the base and projecting thereabove, and a cover, generally referred to by the numeral 13. It is to be noted that the bulk carrier 10 is generally rectangular or square in outline, which shape is the preferred shape for shipment and storage purposes.

ponents of the bulk carrier 10 may be secured together by various types of conventional fastening means, including stapling, gluing, etc.

The base 11 is folded from a fiat blank, and includes a bottom wall 14 which has extending along the edges thereof

flaps

15 and 16. The flaps 16 differ from the flaps 15 in that they are provided with extension flaps 17. Also, the flaps 16 are provided with diagonal fold lines 18 at their corners to facilitate the folding of the assembled base 11 to a relatively flat state for storage and shipment, if so desired. I

In the assembled form of the base 11, the

flaps

15 and 16 are connected together by extending the flap extensions 17 into overlapping relation with respect to the flaps 15 and suitably securing them to the flaps 15, as by staples 19 illustrated in FIGURES 1 and 2.

Each of the sleeves 12 is folded from an elongated blank so as to have four sides. The free edges of the blank from which the sleeves 12 are formed are suitably connected together by, for example, an elongated cloth the sleeves 12 may be reinforced by cloth tape (not shown).

The cover 13 is of the same construction as the base 11, and is formed from a blank so as to provide a top wall 21 having a plurality of flaps extending thereabout. These flaps include a pair of flaps 22 disposed along opposite edges, and a second pair of flaps 23 disposed along the other of the opposite edges. The flaps 23 differ from the flaps 22 in that they are provided with flap extensions 24. In the assembled form of the cover 13,

thefiaps

22 and 23 are disposedin depending relation to provide a depending peripheral flange. The

flaps

22 and 23 are secured together by the flap extensions 24, wliich flap extensions overlap the flaps 22 and are secured thereto by suitable means, such as by staples 25, as is best shown in FIGURE 1. Also, the flaps 23 are provided with diagonal fold lines 26 which permit the folding of the assembled cover 13 to a relatively fiat state for storage and shipment, when desired.

Depending upon the particular requirements of the bulk carrier 10, the individual sleeves 12 and the base 11 and the cover 13 may remain as individual components which are releasably secured together, or the elements may be secured together to form a complete container which cannot be easily broken down into individual components.

In the form of the invention illustrated in FIGURES l and.2, the sleeves 12 are rigidly secured to the base 11, and the cover 13 is rigidly secured to the sleeves 12. The sleeves 12 may be rigidly secured to each other by such fastening means as adhesive, staples or tape. The relative proportions of the sleeves 12 are such that they will nest together having corners disposed along a common center line and will snugly fit within the flanges of the base 11 and the cover 13. The lower parts of the sleeves 12 are secured to the

flaps

15 and 16 of the base 11 by staples 27, and to the

flaps

22 and 23 of the cover 13 by staples 28.

Under certain conditions, it will be desired to form the bulk carrier 10 so that it is reusable and can be knocked down for shipment. In such event, the individual sleeves 12 will not be rigidly secured to each other, but may be secured together by a strap, such as the strap 29 illustrated in FIGURE 5. The strap 29 will extend about the sleeves 12 and may be removed therefrom so that the sleeves may be disassembled. Also, the base 11- and the cover 13 will not be rigidly secured to the sleeves 12. If desired, suitable strapping may be used for retaining the cover and base in clamping relation with respect to the ends of the sleeves.

The size of the bulk carrier 10 may vary as is desired. However, it is contemplated to form the bulk carrier 19 of the same size as a conventional pallet so that it may be readily handled by a fork lift truck. To this end, the base 11 may be provided with a plurality of feet 30. The feet 30, in the preferred embodiment, will be nine in number and will be secured to the underside of the bottom wall 14 about the periphery of the base 11 in the arrangement illustrated in FIGURE 2. In addition, there will be one of the feet 30 at the center of the base 11. The spacing of the feet 30 will be such that the tines of a fork lift truck fork may fit therebetween and engage the underside of the bottom wall 14.

It will be readily apparent that the presently proposed bulk carrier 10 is actually four boxes formed in one for ease of handling and ease of construction, as well as simplicity of construction and minimum costs. Because of the construction and since the pressures exerted on the side walls of the individual sleeves 12 will bear against only relatively short side walls, as opposed to long side walls in containers of equal size, the problem of the side walls bulging is minimized. Further, the construction of the sleeves 12 and the manner in which they are assembled, prevent endwise collapsing of the bulk carrier 10 so that a number of the bulk carriers 10 may be stacked one upon the other. The feet 30 will be of a size to properly transmit the loads from one bulk carrier to another. Also, it will be apparent that the feet 30 i are arranged so that the pressures exerted thereby on a next lower bulk carrier will be taken properly by the sleeves.

Because the bulk carrier 10 is divided into at least four. compartments, it will be apparent that, when desired, the

individual bulk carrier 10 may carry more than one kind 1 of material. For example, three of the sleeves 12 may.

be filled with one material, and the fourth sleeve filled is provided with .a bottom wall 33. The bottom wall 33 is provided with a centrally located, relatively large dispensing opening 34. The bottom wall 33 is also provided with radiating slots 35 whose positions correspond to the positions of the walls of the sleeves 12. The slots 35 have extensions 36 which extend up into the body 32.

When the filling device 31 is utilized, it is located on the bulk carrier 10 after the cover 13 has been removed It is centrally located with respect to the sleeves 12 and the upper edges of the sleeves 12 extend into the slots 35 and the slot extensions 36. v The bottom wall 33 of the filling device 31 is disposed below the upper edges of the sleeves 12. The size of the filling device 31 is such that the bulk material may be directed thereinto from a spout or other type of dispensing unit without waste.

The filling device 3-1, when centered on the sleeves 12,;

will simultaneously dispense the bulk material into the sleeves 12 in equal quantities. After the filling of the sleeves 12 has been completed, it is merely necessary to pull the filling device 31 off of the sleeves 12,after which the cover 13 maybe positioned on the sleeves 12 to complete the bulk carrier 10.

From the foregoing, it will be seen that novel. and advantageous provision has been made for carrying out the desired end. However, attention is again directed to the fact that variations may be made in the example embodiment disclosed herein without departing from the spirit and scope ofthe invention, as defined in. the appended claims.
