1 Claim.

This invention rel-ates to improvements in assembled partitions for cardboard boxes.

The partitions or dividers now generally used in cardboard boxes are of the notched or slotted varieties, and the several notched pieces need to be carefully set together by hand and inserted in the box; all of which requires tedious and time consuming labor, thus considerably enhancing the cost of producing the cells in the boxes by the use of such partition means.

It has been attempted to obviate such notched partitions, by securing several plies or strips of cardboard together, as by the use of glue, and then bending the wings upon score lines outward from the main center stem, as is indicated in the patent to Gemmill, #2,105,645. However, that form requires score lines whereon to bend the Wings, and thus necessitates an extra scoring operation; and furthermore, the main stem must thereby also consist of many superposed plies or layers, requiring half as many layers as there are cells in the box, so that such form makes the central stem too thick and requires too much material, especially where a large number of cells are required in the box. Moreover, the glue used in such forms for securing the strips together in those partition units tends to give oiT odors, etc., which becomes injurious to candy and the like when packed therein.

The main object and purpose of this invention is to provide an efiicient partition means for cardboard and paper boxes which can be readily manufactured and quickly and conveniently inserted in the box, and is adapted for producing any desired number of cells, at a minimum of st.

A more particular object of this invention is to provide partition means comprising several units, each of which has several sections or wings firmly secured together, so as to avoid the use of slotted pieces which require considerable time for combining and inserting them in the box; and to have the wings of each unit seamed together so as to be readily bent apart on the seam line, to avoid the use of glue and to obviate the need of any extra score lines whereon to bend the wings apart.

A further object of this invention is to provide an improved method for making such partition units, so that they can be readily manufactured and quickly installed in the box, at a minimum of cost for material and for labor; and which will provide flexibility so as to readily produce any number of cells desired in the box.

These and various other objects and advantages are attained with this invention, as will become apparent from the following description, taken in connection with the accompanying drawing illustrating this invention in its preferred form of construction, it being apparent that other forms and modifications may be resorted to for carrying out the objects and purposes of this invention.

In the drawing:

Fig. 1 is a plan View showing part of a pair .of superposed sheets of material seamed, together along the middle line, which are then cut across the seam into strips to provide the partition units.

Fig. 2 is a plan view of a partition unit in its flat shape.

Fig. 3 is an edge view of such a flat unit.

Fig. 4 is a perspective view of a partition unit with its wings unfolded along its seam line, ready for use.

Fig. 5 is a plan view of a box having several of my partition units set in place therein to provide the cells.

Fig. 6 is a section-a1 View thereof, taken on line 66 of Fig. 5.

The drawing illustrates this invention in the preferred form of construction, and it discloses the preferred method of making the units and setting them in place in a box, for providing the desired number of cells in the box.

In carrying my invention into effect, in making this improved partition unit and utilizing it for providing cells in a box, two layers or sheets l0 and II of material, preferably fibrous material, such as cardboard, paper or the like, are laid one upon the other and are secured together by running .a seam l2 along their middle line. This is readily and economically done by means of a machine in the shop; and an ideal manner is .to employ tWo sheets of such material which are superposed on a roll, and run these superposed sheets together from the roll thru the sewing machine, thus conveniently securing the pair of sheets together by the seam.

This united pair of superposed sheets is then cut across, laterally, as indicated by the dot-anddash lines 13, shown in Fig. 1 of the drawing, to provide the partition means or units [4 of the desired size, each of which consists of two strips [5 and I6 having part of said seam l2 extending along the middle cross line thereof, substantially as shown in Figs. 2 and 3. This cutting is preferably done by laying a number of such pairs of seamed sheets upon each other and cutting them together into the desired size by means of a cutting machine in the shop.

These partition units are then in their flat shape, and can thus be readily stored and shipped; and when it is desired to use the same the sections of said strips [5 and. [6 are then conveniently bent apart on the seam l2, so as to provide four wings or sections l5, l5, l6 'and I6", which extend substantially at right "angles to each other, as shown in Fig. 4. The seam I2 has thereby provided the securing means along the middle line of the strips for securing them firmly together, and it has also provided a score line or means whereon the four wings are easily bent apart, and without any necessity of providing extra score lines or requiring any extra scor-' ing operation.

These partition units with their wings bent apart are next readily set into the box [1 whenever desired for use, and they areso arranged therein'that a wing of one unit overlaps a wing of an adjoining unit, and so as to provide substantially rectangular cells in the box, as shown in Fig. 5, ready to receive the 'articles'therein.

With this invention I provide an improved and economical partition means and manner of manufacturing it, so that it can be readily constructed and quickly set in place in the box, all at a minimum of cost. v I moreover avoid the lengthy and tedious labor required in setting'together the customary notched type of partition means in the box; since with this method I canrun two superposed sheets from a roll thru the sewing machine, and thus readily secure them together. I also avoid the troubles encountered with the other form, which requires triple and quadruple layers in a unit, and further requires the double steps of first gluing the sheets together and then also providing score lines whereon to bend the wings apart.

This partition means furthermore provides flexibility, as the several units can be readily set together in the box, with the adjoining wings overlapping, as shown in Fig. 5, so as to conveniently provide any number of cells desired in a box, by the simple use of this one inexpensive form of unit.

I claim:

In a rectangular cardboard box, a plurality of partition units, each consisting of a pair of strips of fibrous material which are secured together by a line of stitches extending across the middle thereof, providing four alike wings which are readily bent apart on each stitch line and extend substantial-1y at right angles to each other, said units with their wings so bent apart being positionedin the box to have at least each of two wings of each unit substantially fully overlapped by a wing of an adjacent unit, each pair of overlapped wings being parallel and in face contactme; relation, thereby readily producing a selected number of similar sized substantially rectangular cells in the box.
