1 Claim.

The invention relates to new and useful improvements in a foldable fiber container which is especially adapted for crating eggs, fruits and the like for commercial handling.

An object of the invention is to provide a fiber container which may be made from a single rectangular blank by slitting and scoring wherein the container when assembled includes two substantially identical cells of equal capacity, the Walls of which are rigidly connected and housed solely within a bottom wall, side walls and a cover when the container is closed.

A further object of the invention is to provide a container of the above type wherein the back wall of the container is stitched to the rear walls of the cells and the front wall of the container is stitched to the front wall of the cells, thus providing a rigid container structure before loading and closing.

A still further object of the invention is to provide a container of the above type wherein the inner end walls of the cells are provided with flaps which are folded back onto the outer side wall of the cell and stapled thereto.

A still further object of the invention when found desirable is to provide a liner which reenforces the bottom wall of the container and also the end wall of the container.

A still further object of the invention is to provide when found desirable a liner for the container which has extensions adapted to serve as a cover for the container, thus making a double wall cover as well as double wall ends and double wall bottom.

These and other improvements will in part be obvious and will in part be hereinafter more fully disclosed.

In the drawing:

Figure 1 is a plan view of a body blank which has been slit and scored so that a container may be formed therefrom embodying the invention;

Figure 2 is a. perspective view showing the blank as folded so as to provide cells, the front wall of the blank being unfolded so as to show the flaps for securing the cells in assembled position;

Figure 3 is a view similar to Figure 2, but showing the rear wall as stitched to the cells and also the front wall as folded so as to provide a front wall for the container which is stitched to the flaps and the front side walls of the cells;

Figure 4 is a view showing the container closed and sealed by a sealing strip;

Figure 5 is a perspective view on a smaller scale showing a slightly modified form of con- 2 struction wherein the fiaps extend to the full height of the front side walls of the cells;

Figure 6 is a longitudinal sectional view through the container showing a modified form wherein the container is provided with the liner extending lengthwise of the bottom and to the full height of the end walls;

Figure '7 is a longitudinal sectional. view showing a further modification wherein the liner at each end thereof has an extension which serves as an inner cover when moved to closed position; and

Figure 8 is a longitudinal sectional view through the container showing a further modification wherein the liner at one end thereof only is provided with an extension forming an inner cover extending the whole length of the container.

The invention has to do with a fiber container which is made from a single blank, preferably of corrugated board. The blank is substantially rectangular in outline and is slit along parallel lines. so as to provide side walls which are in tegral with the bottom of the container and a cover section which is integral with the rear side wall. These slits also provide end walls which are integral with the bottom, side sections projecting laterally from the end sections and forming the side walls of cells and an inner end section for the cells which are provided with flaps adapted to rigidly connect the walls of the cells.

Referring more in detail to the drawings, the blank from which the container is formed is shown in Figure 1. It is substantially rectangular in shape. The blank is slit along the lines I, I, so as to provide a bottom 2, a rear side wall 3 and a cover 4. The rear side wall is separated from the bottom by a score line 5- and the cover is separated from the rear side wall by a score line 6. The cover 4 is provided with a flap 1 which is separated from the cover by a score line 8. The blank is also slit along the lines 9, 9 to provide a front wall I0 which is separated from the bottom by a score line I I. These score lines, of course, are not cut through the blank but are of sufiicient depth to aid in forming a fold line. The blank is of sufiicient width so as to provide an end section I2 separated from the bottom by a score line I3.

At the other end of the bottom is an end section I4 separated from the bottom by a score line I5. These end sections when folded to an upright position relative to the bottom form the end walls of cells in which the product is to be placed. The end section I2 is provided with a section It which is separatedfrom the end I2 of this cell. The flap 28,

by a score line H. At the other side of the end section there is an extension |B separated from the end wall |2 by a score line l9. These sections l6 and I8 when in folded position form the side walls of one of the cells. There are similar sections 20 and 2| at the sides of the end section M which are separated from the end sections by score lines 22 and 23 respectively. These extensions 20 and 2| form the side walls of the other cell in which the product is placed.

The section l6 has a further extension 24 separated from the section l6 by a score line 25. There is a similar extension 26 carried by the section 20 and separated therefrom by a score line 21. These extensions 24 and 26 form the inner end walls of the cells. These end walls are each provided with a flap, one of which is indicated at 28 and the other at 29. These flaps are separated from the extensions carrying the same by score lines 30, 30. This blank lends itself to slitting and scoring operations as differentiated from die cutting. This blank may be shipped in flat condition and then assembled for use as a container.

In Figure 2 of the drawings the end section l2 and I l are folded upwardly from the bottom. The sections l8 and I8 are folded so as to form the side walls of one of the cells. The extension 24 is folded so as to form an inner end wall if used, is folded onto the outer face of the front side section of the cell and may be stapled thereto so as to hold the cell rigidly in assembled position. The end wall I4 is likewise folded to vertical position to form the end wall of the other cell. The extensions and 2| are folded in position so as to form the side walls of this other cell. The extension 26 is folded in position so as to form the inner end wall opposed to the end wall M. The flap 29 is folded onto the outer face of the front side wall of the cell and may likewise be stapled to the front wall for forming a rigidly assembled cell. These two cells just described are identical in shape and height and are therefore of equal capacity. The section 3 is folded along the score line 5 to the position shown in Figure 2 and this provides the rear wall of the container. As viewed in Figure 2, the front wall ID has not yet been folded to vertical position.

In Figure 3, this front wall In is shown as r folded to a vertical position, and when so positioned it contacts in part with the flaps 28 and 29 and in part with the front side walls l8 and 2| of the cells. As shown in this Figure 3, the rear wall is stitched, preferably by staples indicated at 3|, to the rear side walls of the cells. Likewise the front wall In is stitched preferably by staples 32, 32 to the flaps and to the front side walls of the cells. This makes a very rigid container construction ready for loading.

It is noted that the flaps 28 and 29 do not extend to the full height of the side walls as shown in Figure 2. These flaps space the front wall ID from the side walls l8 and 20, thus providing a pocket. This will permit the flap 1 of the cover, when in closed position, to be inserted in the pocket between the front wall In and the front side walls l8 and 2| of the cells. After the cover has been moved to closed position and the flap placed between these sections, then a sealing strip 33 may be applied which extends from one end of the container to the other and firmly secures the cover in closed position.

In the modification illustrated in Figure 5,

the flaps on the end walls of the cells extend to the full height of the side walls and the flap 1 of the cover is cut away in the central portion thereof so as to form two flaps l 1 which may be inserted between the front wall H! of the container and the outer portions of the front side walls l8 and 2| of the cells.

The container above described is made from a single foldable fiber blank which may be readily folded and assembled to provide independent cells of equal capacity housed within a bottom wall, side wall and a cover wherein the front and rear walls when in assembled position may be stitched to the cells for providing a rigid construction. For certain uses it may be desirable to strengthen the bottom and end walls.

In Figure 6 there is shown a liner 33 which extends the full length of the bottom wall 2 and likewise the full width of the bottom wall. This will reenforce the bottom wall. The partitions 24 and 26 are shortened slightly to permit the liner to extend beneath the same. The liner has an extension 34 which serves as a reenforcement for the end wall l4 and also an extension 35 which serves as a reenforcement for the end wall I2. The liner at the ends extends all the way to the upper end of the end walls of the cells.

In the modification shown in Figure '7, the liner 33 is provided with further extensions. The extension of the end liner wall I34 provides an inner cover section 36 and the extension of the end wall 35 provides an inner cover section 31. These inner covers 36 and 31 are each provided with flaps 38, 38 and the flaps when the covers are in closed position extend between the partitions 24 and 26. This makes a. container which has a double bottom wall, double end walls, double front and rear walls and a double cover.

In Figure 8, the end liner wall 35 has an ex-- tension which forms an inner cover 39. This inner cover extends from one end of the box to the other and is provided with a flap 40 which extends down between the end wall l4 and the liner end wall 34. This also produces a container wherein there is a double cover as well as double walls throughout.

While the flaps 28, 29 have been illustrated and are preferred, it will be understood that they may be omitted and tape employed for securing the end walls of the cells to the front side walls of the cells.

It is further understood that minor changes in the details of construction may be made without departing from the spirit of the invention as set forth in the attached claim.

I claim:

A foldable fiber container formed from a substantially rectangular blank, said blank being scored and slit so as to provide when assembled for use a bottom wall, side and rear walls integral therewith, a cover member integral with said rear wall, cell end walls integral with said bottom wall, front and rear cell side walls formed integral with each end cell wall, inner end cell walls formed integral with each rear cell wall and carrying flaps at the ends thereof, said inner cell walls being dimensioned so as to extend from the bottom to the cover when the container is closed for supporting said cover and also dimensioned so as to extend transversely of the container between the inner ends of the front side cell walls and with the flaps folded flat against the outer faces of said front cell side walls, said container front wall being folded into vertical position and against said flaps, said flaps spacing said front container wall from said front cell walls to form a pocket stitching means passing through said container front wall,
