(ci. zza-1s Claims. 1

This invention relates to a palletlzed containe In the packaging industry it has been the cus tom to individually package a certain product and then package a considerable number of the immediate preceding recited packages in a larger, overall or master container and ship such container to a single consignee. Such master container may weigh as much as 400 pounds which limits its manual handling. l

The chief object of the present invention resides in forming the said container so that it can be stacked and readily handled by the so-called fork of a lift truck, with all the attendant advantages resulting therefrom.

The chief feature of the present invention consists in forming integral with a portion of the said container, a plurality of tubular structures adapted to contain reenforcement filler material so that in effect the bottom of the container, is palletized or cleated as it were to accommodate fork tines.

Other objects and features of the invention will be set forth more fully hereinafter.

'I'he full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings, Fig. 1 is a plan view of a detial part of the invention.

Fig. 4 is a perspective view of an end portion of the accordion type ller in slightly extended relation.

Fig. 5 is a perspective view of a rigid, nller element.

"veloped blank of a portion of a double bottom l In Figs. l and 2 of the drawings, IU indicates a pair of side Walls and hinged creased connected therewith are the end walls I I. 'There is also pro,- vided a manufacturers joint I2. Hinge-crease connected to a pair of opposed Walls, as for example sides Ill, are the bottom forming members I3 which herein are shown of a size or to form a double bottom. They may be of lesser size if desired. Hinge-crease connected to the corresponding edges of the other pair of walls, for example the endwalls I I, are the flap portions Il.

Each portion It is hinge-creased as at I5, I6, I'I and I8, defining portions I9, 2U, 2| and 22 ref spectively. The box is suitably erected into tubular formation and the flap I2 is stitched to the end wall II as at 23. The two bottoms I3 are turned inwardly and lap each other since they are of the size as shown clearly in Figs. 1 and 3, and form an end closure.

Then the flaps I4 are turned inwardly toward each other and the remainder of the portions I9, 2l and 22 are disposed in tubular formation as shown clearly in Fig. 3 and are suitably secured together in such position and to the lapped bottom portions I3 as indicated by stitching 24. This stitching, if used, is applied near each end of the tubes. If adhesive is used it would be coextensive with the tubes. The resulting structure is an open top container having tubular like cleats integral with the bottom or end closure and externally disposed thereon adjacent side edges thereof and substantially coextensive crosswise upon and with the walls to which they are united.

Containers without cleats, of this general type,

are usually of corrugated board although the same may be fabricated of solid fibre board as these terms are broadly used in the paper board box industry. f

To insure sufllcient strength in the palletizin tubes. inserts are provided which in Fig. 5 may comprise a stick of wood or pressed board and of the proper dimensions as to length, width and thickness so as to be slidably receivable when telescopically associated therewith. Such an in sert may be held therein by suitable means or held by friction. In Fig. 5 such a solid insert is designated by the numeral 26. Such an insert may comprise individual strips of board. Same may be tape banded if desired.

In Figs. 2 and 4 there is illustrated the preferred form of reenforcing filler 21. It is. preferably formed from a single sheet of corrugated board that is of double face character having the two liners 28 and 29 with the intermediate corrugated layer 30. Herein such a board has its corrugated layer cut through at each hinge connection and alternate hinge connections are formed by one linen-the opposite liner being severed in registration therewith, as shown in Fig. 4, so that successive hinge formations fold oppositely and are alternately formed by the two liners 28 and 29. It may comprise a crease-folded structure if desired.

When a sheet of corrugated board is thus slithinge fabricated, the same is collapsed from the fiat sheet to the position shown in Fig. 4 and then further collapsed to the position shown in Fig. 2. When so collapsed it is telescopically associated within a tube formation. as previously described. and thus the tube is substantially lled and thus reenforced. The iiller tends to expand inthe tubular pocket and cling to the walls thereof. Preferably the accordion type is disposed as shown in Fig. 2 although if desired it may be disposed in a position displaced 90 with respect to that shown in idg. 2%.

Herein also the tubes supporting portions M are shown suitably secured to the bottom forming walls i3 as by the staples 25. The container so palietized may be provided withpany suitable top or cover. In Fig. 2 such a cover is indicated generally by the numeral si.

It will be obvious, of course. that the tubular pockets thus formed may be disposed closer to the parallel edges oi the container or n f' f closer relation to each other, depending upon the position of the first creases i5 in the portions M and i9, 2d, 2i and 22; Strength disposition and the position of the forks of iiiter truck will determine the positions of the cleat constructions.

Whenever the individual load in any container is in excess of that which can be safely accompmodated by the two ends disposed cleats, without crushing of the cleats and/ or the container, there Amay be provided an intermediate cleat or cleats, not shown. Each could be formed by a. Ueshaped member, having the length of the tubular pockets illustrated and a depth corresponding thereto and of any desired width. Such ill-shaped pocket forming member may have outwardly and/ or in wardly vdirected flanges suitably secured to and through the two bottom portions iii. The reu sulting intermediate tubular pocket or pockets 'would then be lled by a iler structure of thecharacter previously described. l

While the invention has beenillustrated and described in great ,detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character. The several modidcations dcribed herein es 'well as others which will readily suggest the-rn- 4 selvestopersomskilledinthillrhallaroolll sidered to be within the vention, reference being 'had to claims.

The invention claimed is:

1*. In a paper board and the like container having tour sequentially connected side walls secured together in tubular formation, the combination therewith of end forming'aps, each hingediy connected to the adjacent edge of a wall and foldable inwardly for end closure purposes. at least two of said flaps having creases therein disposed in spaced relation to the hinge connection thereof to form tubes external of and integral with the end closure. the resulting tubes being disposed inwardly of and parallel to the adjacent edge of the container.

2. A paper board container as defined by claim l wherein each tube includes a tube reeniorcing nller of folded corrugated board.

3. A paper board container as defined by claim 2 wherein the folded corrugated board ller comprises an accordion fold relationship therein.

e. A device as defined by claim 3 wherein the accordion folded ller is of double face board. the faces at opposite sides being alternately slit for successive hinge folds.

5. In a paper board and the like container hav@- ing four sequentially connected side walls secured together in tubular formation, the combination therewith of end forming flaps, each hingediy connected to the adjacent edge of a wall and foidable inwardly for end closure purposes, at least two of said flaps having creases therein disposed in spaced relation to the hinge connection thereof to form tubes external of and integral with the end closure, the resulting tubes being disposed inwardly of and parallel to the adjacent edge of the container and substantially coextensive in length with the length of that edge.
