Application July 29, 1941, Serial No. 404,490

2 Claims.

This invention relates to a box for gun cartridges and has for its principal object the provision of a simple, economical, easily manufactured, and highly eflicient partition member for cartridge boxes which will maintain each individual cartridge separated and cushioned from all of its neighbors.

Other objects of the invention are to provide a partition member for cartridge boxes which will reduce the amount of cardboard usually required, which can be quickly and easily manufactured by automatic machines, and which will consist in its entirety of a single sheet of material such as cardboard.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efliciency. These will become more apparent from the following description.

In the following detailed description of the invention reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing:

Fig. 1 is a perspective view, partially broken away, illustrating the improved partition member in place in a typical cartridge box;

Fig. 2 illustrates the blank used for forming the partition member;

Fig. 3 is a perspective view illustrating the blank with the separating tabs in the erected position;

Fig. 4 is a detail view illustrating an alternate form of cut for the separating tabs to provide means for holding the tab erect; and

Fig. 5 is a detail view illustrating the tab of Fig. 4 in the erected position.

In the drawing a typical cardboard cartridge box is illustrated at IU holding typical gun cartridges II.

This invention relates more particularly to the partition structure employed in the box I0. This partition structure consists of a single sheet or blank I2 of cardboard or other suitable material. The blank I2 is scored longitudinally through its middle by means of a score line I3 so that the two halves thereof can be folded together along this line.

Each half of the blank I2 is similarly die cut with a plurality of uniformly spaced, U-shaped cuts l4 each of which outlines a partition tab I5. Along the line where each tab I5 joins the blank I2 a {old line I6 is scored therein. The

tabs in each half Of the blank l2 are positioned exactly opposite the tabs in the other half so that when the two halves are folded together, the tabs therein will align opposite each other. Before the blank I2 is folded, all of the tabs are folded upwardly to a position at right angles to the blank [2, as shown in Fig. 3. The blank is then folded along the line 13 with the tabs projecting oppositely outward and inserted in the box H] where it will assume a position as illustrated in Fig. 1. Each series of tabs Will define a series of uniform, vertical pockets for receiving the cartridges II. The cartridges are inserted with the bullet downward. The tabs are positioned adjacent the top of the box and are of suflicient length to cover the powder chamber portion of the shells.

After the partition structure is in place in the box and after cartridges are in place therein, the partition tabs I5 cannot fold or move and the blank cannot open up on its fold line I3 so that a solid substantial structure is formed.

It is preferred to run a line of glue on the back side of the blank I2, as indicated by the broken line H, so that when the two halves are pressed together they will adhere to each other.

In Fig. 4 means for holding the partition tabs I5 perpendicular to the blank is illustrated. This is accomplished by cutting the tabs so that the out line thereof at one extremity will extend inwardly and outwardly as shown at I8 in Fig. 4. This out line defines a finger I9 which does not fold upwardly with the tab itself but which can be folded upwardly from one end of the tab opening, after the tab is erected as shown in Fig. 5, so as to provide a brace which will act to support the tab in its perpendicular position. This finger I9 requires no additional material and provides a very effective means for holding the partition tabs at right angles to the blanks until the box has been filled with cartridges.

While the invention has been described as particularly applicable for use with gun cartridge boxes, it is not limited to this particular use since it will be equally valuable for packing any articles where individual separation is desired.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is:

1. A partition member for cartridge boxes comprising: a blank of sheet material folded back on itself along its medial line to form a longitudinal partition of double thickness; outwardly extending tabs cut from the material of each thickness opposite similar tabs in the other thickness, the tabs in the two thicknesses projecting oppositely outward from each other throughout the length of the longitudinal partition; and fingers cut from the material of the blank and hinged thereto at the extremity of and at right angles to each tab, said fingers extending outwardly between the outward position of the tab and the plane of the blank to obstruct the return of the projecting tabs to their former position.

2. A partition structure for a cartridge box comprising: two similar vertical longitudinal partition walls positioned back-to-back; verticallyelongated, openings through both walls in parallel spaced-apart relation; vertical tabs projecting perpendicularly outward from both Walls, each tab being secured along one side of one of said openings; a finger member cut from the material of each wall and secured along one end of each opening, said finger members projecting outwardly from said walls between said tabs and said openings to prevent the return of the tabs thereto.
