Il WILLIAM QBARRET'I FIG 3 III BY NICHOLAS MSIDER 36 do? Q- Ww ATTORNEY United States Patent O 3,236,433 CONTAINER William C. Barrett, La Grange, and Nicholas M. Sider,

Des Plaines, Ill., assignors to International Paper Company, New York, N.Y., a corporation of New York Filed Apr. 12, 1963, Ser. No. 272,712 6 Claims. (Cl. 22915) This invention relates to a container and more particularly to an insert or inserts for a container.

It is often desirable to divide a container into compart ments to accommodate individual articles or smaller packaging units. It is a principal object of this invention to provide an insert for a container which is adapted to divide the container into a plurality of compartments,

It is a further object to provide an insert for a container which is formed from a one-piece blank of foldable sheet material, such as corrugated paperboard, and which can be set-up without the use of extraneous means, such as glue or staples.

Another object is to provide an insert for a container having means to reinforce the side walls of the container.

A further object is to provide an insert for a container having means to reinforce the corners of the container.

Another object is to provide an insert for a container having means to anchor the insert in the container.

It is further often desirable to provide a container with compartments in two or more tiers. It is, therefore, still another object of the invention to provide a plurality of inserts for a container which are adapted to divide the container into a plurality of compartments in two or' more tiers.

It is a further object to provide a plurality of inserts for a container having means to reinforce the side walls and corners of the container and means to anchor the inserts in the container.

Another object is to provide a plurality of inserts for a container having means to support the inserts stacked one atop the other to form a tier effect and to lock the stacked inserts in place.

Other objects and advantages will appear from the following description and drawings, in which:

FIG. 1 is a plan view of a blank from which an insert of this invention is made;

FIG. 2 is a perspective view of two inserts in accordance with FIG. 1 (the uppermost insert being shown partly as sembled; the lowermost insert being shown fully assembled), one overlying the other in position to be stacked one atop the other;

FIG. 3 is a perspective view of a container showing inserts in accordance with FIG. 2 positioned therein;

FIG. 4 is a fragmentary perspective View of a blank from which a modified version of the insert of the present invention is made; and,

FIG. 5 is a fragmentary perspective view showing the corner of the insert formed from the blank of FIG. 4.

The insert 40 shown in FIGS. 2 and 3 is formed from a onepiece blank 1 (FIG. 1) of suitable sheet material, preferably corrugated paperboard. It may also be constructed from other materials, such as heavy paper or paperboard, depending upon the requirements of use.

The blank 1 has longitudinal and transverse fold lines 2 and 3 and longitudinal and transverse slits 4 and 5 which generally dene bottom parts (including first and second bottom panels 6 and 7), partition parts (including first and second transverse partition panels 84 and 9 and first and second longitudinal partition aps 10 and 11), side parts (including first, second, third and fourth side panels 12, 13, 14 and 15), corner parts (including rst, second, third and fourth corner flaps 16, 17, 18 and 19) and end parts (including first, second, third and fourth end aps 20, 21, 22 and 23).

3,236,433 Patented Feb. 22, 1966 Means are provided to interlock the partition parts, for a purpose further to be described, in the form of slots 24 in partition panels 8 and 9 and slots 25 in partition ilaps 10 and 11. Slots 24 extend inwardly from the upper edges 8a and 9a of the partition panels 8 and 9 and approximately one-half way therethrough and slots 25 eX- tend inwardly from the lower edges 10a and 11a of the partition flaps 10 and 11 and approximately one-half way therethrough. The ends of the slots 25 are preferably tapered or beveled as indicated at 26 so that the slots 25 may be mated with the slots 24 with greater ease when the insert is being set-up.

The partition panels 8 and 9 may be cut, as at 27, to provide stacking and locking tabs 28 which are adapted to be received in suitable openings or cut-outs 29 in the bottom Ipanels 6 and 7 of a like insert when arranged one atop the other.

To assemble the insert from the blank of FIG. l, t-he blank is folded along the transverse fold lines 3a, 3b, and 3c so as to bring the partition panels 8 and 9 into abutting contact with each other and perpendicular to the bottom panels 6 and 7. The partition flaps 10 and 11 are then folded perpendicular to the side panels 12 and 13 and as the side panels 12 and 13 are folded perpendicular to the bottom panels 6 and 7, the downwardly opening slots 25 in the partition aps 10 and 11 are tucked into the upwardly opening slots 24 of the partition panels 8 and 9 to interlock the partition parts as shown in FIG. 2. In their fully assembled condition the partition panels 8 and 9 are perpendicular to the partition flaps 10 and 11 and the partition panels and aps are perpendicular to the bottom panels 6 and 7.

The side panels 14 and 15 are then folded perpendicular to the bottom panels 8 and 9 and the corner flaps 16, 17, 18 and 19 are folded inwardly at a slight angle to the side panels 12, 13, 14 and 15 so as to overlie the corners of the bottom panels 6 and 7. Then the end flaps 20, 21, 22 and 23 are folded perpendicular to the bottom panels 6 and 7 and into contact with the free edges of the corner aps 16, 17, 18 and 19, to complete the assembly of the insert.

The assembled insert 40 may now be inserted into a container to divide it into compartments. The container may be a regular slotted container, as shown at C in FIG. 3, having side walls 30, end walls 36 and top and bottom closing means including top closing aps 31 and bottom closing flaps (not shown). However, the insert is adapted for use with any rectangular container which is loaded through its top.

A single insert divides the container into four compartments in one tier. If more than one tier of compartments is desired, like inserts are stacked one atop the other until the desired number of tiers is obtained.

Referring to FIG. 2, the ease with which inserts are stacked and locked in a stacked position as a result of their unique construction is readily apparent. It is only necessary to insert the tabs 28 cut from partition panels 8 and 9 in the lowermost insert into the openings 29 in the bottom panels 6 and 7 in the insert stacked on it to stack them one on the other and lock them together.

Two inserts stacked one atop the other in this manner are shown in position in the container C in FIG. 3. Thus positioned, they divide the container into two tiers of four compartments each.

When lstacked one atop the other, the upper edges of the panels 12, 13, 14 and 15 and the flaps 16, 17, 18 and 19 of the lowermost insert provide stacking support at the sides and corners for the insert placed on it. This support combined with the support provided along the longitudinal and transverse centers by the partition panels 8 and 9 and the partition flaps 10 and 11 is more than adequate to handle the vertical loads to which the lowe-rmost inserts are subjected.

The inserts are further provided with anchoring iiaps 20, 21, 22 and 23 which enable them to fit snugly within the container.

When the container has been loaded with its contents, the top flaps 31 are folded perpendicular to the side walls 30 to close the container. To further hold and lock the vinsert or inserts in-position in the container and particularly the partition panels 8 and 9 and partition fiaps 10 and 11 perpendicular to the bottom panels 6 and 7 and to each other, the inner top fiaps 31a are provided with cut-outs V352 which are adapted to receive the tabs 28 of the uppermost insert to lock itin place.

In a preferred embodiment where a single insert is being -used to divide a container into compartments in one tier, the height of the insert is substant-ially the same height as the sidewalls of the container. And where two or more inserts are fused to provide compartments in two vor more tiers, the inserts are preferably dimensioned so that the sum of their heights is substantiaily equal to the height of the container side walls. For example, if two insertsfare used, the height of each would be substantially one-half the height of the container side walls.

A modification 41 of the insert is shown in FIGS. 4 and 5. It is identical to the insert 40 except that the corner parts have been changed slightly. Additional longitudinal fold lines 2a and cut-outs 412 have been pro vided to divide the co-rner fiaps into inwardly and outwardly directed flap sections, such as 19a and 19h. Although it takes slightly longer to set-up flaps 19 i-n insert 40, these inwardly and centerdirected flaps provide more support at the corners oftheinsert.
