Patented Jan. 5, 1954 SHIPPING CONTAINER FOR HEAVY BULK MERCHANDISE Jack R. Belsinger, Atlanta, Ga., assignor to Belsinger, Inc., Atlanta, Ga., a corporation of Georgia Application November 8, 1950, Serial No. 194,67 7

1 Claim.

This invention relates to a shipping carton of paperboard material particularly adapted for heavy bulk merchandise such as nails, rivets, and like articles.

It has heretofore been the practice to ship standard quantities, such as one hundred pounds, of such heavy bulk articles in wooden kegs and like containers, largely for the reason that paperboard boxes have not been able to withstand the tests demanded prior to certification of such containers for general freight and express shipments, or such paperboard boxes have been of such complex and expensive construction that their use has been limited by economic factors incident to manufacture or loading thereof.

One of the features of the present invention is the provision of a paperboard box or carton having reinforcing members at the parts which have been found most subject to penetration from the exterior or interior during the shipment of such goods.

Another feature of the invention is the provision of a simple but adequately reinforced carton or box for such materials, which can be handled, loaded, shipped, opened, and discharged without major changes from existing methods employed with wooden kegs in present practice of packing, and with greater facility of opening and discharge than with such wooden kegs.

A further feature of the invention is the provision of a container for such materials, in which the several parts provide reinforced walls at all points of contact of the lading therewith.

With these and other features in view, as will appear in the course of the following description and claim, an illustrative form of practicing the invention is shown on the accompanying drawings, in which:

Fig. l is a perspective view of the assembled, loaded, and sealed container.

Fig. 2 is a perspective view showing upper and lower parts of the container in separated relative position, with the lower part thereof shown in condition for loading.

Fig. 3 is an upright sectional view, on a larger scale, through a side wall and through part of the bottom wall of such a container.

Fig. 4 is a view, on a smaller scale than that of the foregoing figures, showing a blank for forming an end cap.

Fig. 5 is a view on a scale smaller than that of Fig. 4, showing a blankfor forming the side walls of a liner section.

Fig. 6 is a view on the scale of Fig. 5, showing a blank for forming the side walls of an outer section.

Fig. 7 is a view on the scale of Fig. 5, of a reinforcement pad.

In these drawings, the shipping carton or box is made of a paperboard material such as corrugated board, fiber board, or the like. It is comprised of two outer sections and a liner section, the liner section being illustratively secured in the lower outer section during assembly, as shown in Fig. 2. The two outer sections are of identical horizontal cross section, being preferably symmetrical with respect to one another, so that when their free edges are brought into abutment, the adjacent outer surfaces are flush with one another.

To construct the carton or box, two blanks as shown in Fig. 6 are utilized. Each of these blanks has a series of four panels II), ll, [2, l3, and an edge tab l4 illustrated as integral but separated by parallel fold lines I5. Such a blank is folded to form the four side walls for the outer section, with the edge tab 14 folded inside of the panel l0 (see Fig. 2) and stitched by the usual operation with staples l6.

Two end cap blanks are employed, as shown in Fig. 4. Each of these blanks has a central closing portion [8 formed integrally across fold lines I9, 20 with the flanges 2|, 22. Gashes 24 aligned with the fold lines l9 provide corner flaps 25 connected with the adjacent flanges 2| across the extended portions of the fold lines 29. By construction, the opposed pairs of edges of the central closing portion l3, provided at the fold lines i9, 20, are respectively equal to the horizontal dimensions of the wall panels Ill, I2 and II, I3 of Fig. 6. The peripheral flanges 2|, 22 of the blank in Fig. 4 are folded to positions at right angles to the central closing portion IS, with the corner flaps 25 turned to overlap the flanges 22, Fig. 2.

A reinforcing pad 28, Fig. 7, is provided for each of the outer sections. This pad has a surface of essentially the shape and area of the central closing portion I8 of the end cap blank, so that it has likewise the shape and area provided inside of the flanges 2|, 22 thereof when folded at right angles; and it likewise has essentially the same size and shape as the external cross sectional shape of the side Wall blank of Fig. 6 when folded and assembled into the form of a tube. Such a pad 28 is placed over the end of the side wall tube, and then the folded end cap piece is placed thereover, the parts are drawn tightly together, and secured by the staples 30. Thus, on the one hand, the pad 28 holds the central closing portion [8 of the end cap spaced from the adjacent edges of the side wall tube structure and, on the other hand, it tightly fits in this space so that it cannot later be dislocated as a result of internal or external blows upon the carton, and thereby reinforces against perforation and against distortion of the shape of the end cap and side wall structure. This provides a structure as shown by the upper section in Fig. 2.

The end caps are positioned on each of the two 3 outer setidnjhbs so that the overlaps ot the edge tab l4 with the panel 10, in the respective outer sections, can be brought into direct abutment as shown in Fig. 2: that is, the two outer sections are symmetrical with respect to one another.

The blank for the inner liner section, shownin Fig. 5, has the side wall port'ioifsfii f} and 3B, and an edge tab 39 connected integrally across parallel fold lines 40. wise folded and its edge tab 3!! brought inside for overlapping the free vertical edge of the si de Wall 35, and is stitched thereto by staples 4'l, Fi Iihe hor n imen ns 9 3 9 3 are dewa l pan s 3 ,33 o f 'br esp 'x 1'.9 l$ .,th '11 'anelfi 0,. .'L [2 13, t t the. 10 er fisections have tight teles opii ei v r h lmer' ect o V l'l e se'mpldl ner Se ion i hee' trqslwed in i t j 'u er ctie an rowed, wn- I..- ,r'e n n i it le'iv rjed 'eebutethe p tine ha 28. hie i- It'i f e x r ferr d t6 *secure the uner tube in position in this lower u er sec en y., 1es 5. t a t. nefi stap Be n meet d acent. ha' i i bi i of each iree side wall {edge "of the lower outer secbnxe' hown in F This assembled "lower structure, as shown in t e W? ba b 0 F 3 3 1 1 L i i 1 3 ing with the material to 'bef'shipped, It will be noted that the upper opening of "the full internal size of the containen 'and defines the internal volume of this container; wherewlth a tight filling to the level of this 'upper fopening wil produce a tight filling "of the completed package. The lower structure and its contents can be shaken as "an incident 'ofl'oading, "in the usual way, to obtain a tight fillin'g 'with the predetermined'weight of merclian disejtolevel condimen. The upper outer sec tionfis then placed in the 'gener'alpo'sition shown in Fig. 2, and is introduced over the liner s'ecti'onand 'slid telescopinglyfdownw ard into place until the free edges of the outer sections come into abutment and the wall panels forming the outer surfaces of "the side wallsprovide a series of planes across e u m t ne ,S inul newey. t t l abutment of 'thefr'eedges of the outer' sections, the inner surface of the pad l8=provided-in the upper section comes into contact with the upper edge of 'th'e'lin'er structure, Fig. 3. t

The parts may now be held in such condition by applyinga cemented tape Bill extending pe ri'pherally "around the side walls and secured to each sidewall panel of the upper and lower sections. It will be notedthatsuch'tapeis strong in"' te nsion, and that'it extends inplaneacross 'the'abut'inent lines from one section tothe other so that its tensile'strength is efiective to hold the outer members in thejstated'abuttingposition.

The abutting engagementpf the free 'edgesof the tube forming the liner section, with the innersurfaces of the; reinforcing *pads28, further supports these pads against departurefrorn their position,' and prevents'nails from gaining access to'the free edgeof the respective 'padZB, whereby to wedge 'ordeform'these pads from theirpositioned 'shape' and" condition. y

The structure, this filled, assembled and sealed, has doubled walls'throughout, with the several wall panels'held'in position by adjacent wall panels and cap portions; 'and 'with employment of the lower portionsof the liner and the side walls of the 'bottom section for stififening one another during filling, wherewith the upper This blank is then likeportionof thl llirier is held to permit the placing of the upper section thereon. The upper and lower sections of the container have doubled top and bottom walls adjacent the upper and lower edges; and at least tripled walls are provided at the lower and upper parts of the sides; thus affording a great stiffness against deformation under the conditions of shipping and handling. H

When it is desired to open and discharge the container, the tape 50 is slit by a knife, for example, along the lines of abutment, whereupon the upper section can be removed, therewith leaving the lower section as shown in Fig. 2, with the contents eas'i'ly exposed for removal individually or in hand-fulls. Further, the smooth interna walls of the container permit a much more easy discharge, by inversion, than can 'be accomplished by inverting a wooden keg. I

The container has a regular shape, requiring small space for shipment'and storage, and "readily adapts its'elfto position beneath a counter in a hardware store, and permits re-covering by the upper section wh'en'i-t is desirable to prevent the access of dust or moisture to such contents as iron nails.

While a sealing band 50 has been described in detail for holding the seeuens in closed position, it is to be understood that "in place (if the sealing 'band or in 'coi1junction therewith any of "the well-known metal bailing pends may be employed. Such "a bailing band 'is indicated at 5| in Figure 1 oithe-drawings.

It is obvious that the invention i'riay 'b'e employed in other ways than those-illustrated within'the's cope of the appended'claim.
