Description

The invention relates to packaging with cell-type inserts for storing and transporting ammunition for small arms.

A known method of packaging artillery small-caliber cartridges and a device for its implementation according to the patent of the Russian Federation No. 2229681, F42B 39/26, including stuffing cartridges in the links of the tape, folding the tape in a spiral into two branches, installing cartridges head and bottom parts in a horizontal partition and support, respectively, the formation of the assembly, the location of the handles on top of it, the installation of the assembly by the handles on the bottom of the standard metal container and the implementation of the force clamping of the assembly by means of shock absorbers of the airtight lid interacting with the horizon a linen partition of the assembly, and lever-cam locks, characterized in that the folding of the tape in a spiral is carried out, forming the beginning of the spiral along the larger side of the support, having the cross-sectional shape of a standard metal container, while both branches of the spiral are made with a parallel bend of three conjugated links, and the installation of cartridges by the bottom part is carried out in blind decks made in the support and by the head part in through windows made in the horizontal partition.

The disadvantages of the known device include the rather large dimensions of the package, which take up a lot of space in the packaging.

A more perfect device is known - an insert for packaging cartridges, which is the closest in technical essence to the proposed one. (See patent No. 2368866 of 02.22.2008 - prototype), containing two parts located symmetrically relative to each other with front and back sides, while the cells of each part are made in the form of convex outward relative to the back side of the open rows of nests, repeating their profile, at least part of the profile of the cartridge, between the rows of sockets is a longitudinal stress concentrator, and parts of the liner are made with the possibility of folding relative to the stress concentrator before contact with its rear sides. The profiles of the open rows of sockets of the liner are made unidirectional. The stress concentrator between the rows of sockets is made, at least in the form of scoring. Cartridges are placed in the nests of the insert - the base of the sleeve - towards the hub. Due to the elastic properties of the material of the pressed paper of the liner, the cartridges are securely fixed in it. After that, the liner is bent in half and inserted into the box in this form. The insert is located in the box folded in half by the stress concentrator up, the cartridges - by the bullet down, while the parts of the insert diverge to the sides until the cartridges come in contact with the side walls of the box. The lid is closed and the resulting cartridge package is placed, for example, in a special cartridge box.

The disadvantages of the known liner include its low manufacturability associated with its subsequent use. So, due to the elastic properties of the liner of its half, when removing the liner from the box, constantly striving to diverge, change the vertically oriented position of the cartridges that are in its cells, which in conditions of time limited for loading the weapon can lead to delays. In addition, the hygroscopicity of the paper liner and its ability to absorb and accumulate moisture during storage of cartridges will adversely affect the coating of the liners and may lead to corrosion, loss of shape of the liner, which in turn can lead to displacement of the cartridges relative to the elements of the liner until they come into contact with transportation.

The present invention is the creation of a package, in particular, a liner with advanced technological capabilities, providing reliable fixation of the cartridge relative to the elements of the liner and providing unlimited storage time of small arms cartridges without changing their oriented vertical position in the package without contact of the cartridges with each other.

The problem is achieved in that the liner is made in the form of a lattice made of plastic, on the upper plane of which at the intersection of its transverse and longitudinal partitions forming through cells, at least one angular latch-retainer per cell is inserted, which is inserted when the cartridge is inserted into the insert in the annular groove of the cartridge or in contact with the conical surface of the sleeve body and preventing the involuntary displacement of the cartridge relative to the insert.

The retaining petals placed at the intersection of the partitions of each cell are made in the form of a part of a circle, rectangle or square with rounded corners, vertices or sides directed towards the center of the cell.

The petals-clamps in thickness are made equal to 0.1-0.3 of the width of the annular groove of the cartridge.

The height of the baffles of the liner is made equal to 0.8-1.5 diameter of the cartridge case.

The novelty of the proposed technical solution is the implementation of the liner in the form of a lattice made of plastic, on the upper plane of which at the intersection of its transverse and longitudinal partitions forming through cells, at least one angular latch-clamp is made for each cell included in the annular groove of the cartridge or contacting with the conical surface of the sleeve body and preventing its involuntary displacement relative to the liner.

So, the petals-retainers included in the groove or in contact with the conical surface of the sleeve body ensure reliable holding of the cartridge in the insert during transportation, shaking, and falling of the package from a height, since the holding forces of the petals are at least ten times the weight of the cartridge installed in the insert cell.

Signs of the implementation of the petals-retainers placed at the intersection of the partitions of each cell, in the form of a part of a circle, rectangle or square with rounded corners, vertices or sides facing the center of the cell, their execution in thickness equal to 0.1-0.9 width of the annular grooves of the cartridge, and the implementation of the height of the walls of the liner, equal to 0.8-1.5 of the diameter of the cartridge case, are additional features that reveal the specific performance of the main ones, and are aimed at achieving the objectives of the invention.

According to the patent information research, the proposed device is new, the features are significant, non-obvious, industrially feasible and aimed at achieving the objectives of the invention.

In Fig. 1, the proposed insert is schematically represented in isometry, a) with petals-retainers in the form of a quarter of a rectangle with rounded corners falling at each corner of the cell, b) shows a part of the insert with petals-retainers in the form of a quarter of a circle, c) with petals, retainers in in the form of a rectangle with vertices directed along the transverse and longitudinal partitions.

Figure 2 presents a fragment of the liner on the side of the cross-section aa with cartridges installed in its cells.

Figure 3 shows a fragment of the insert along the cross section BB along the diagonal of the cell with cartridges with petals-retainers placed in the annular groove of the cartridge case.

Figure 4 shows the placement of the petals of the retainers in the annular groove of the sleeve on an enlarged scale.

Figure 5 shows the placement of the petals of the retainers in contact with the conical surface of the housing of the sleeve.

The insert is made in the form of a predominantly rectangular shape with rounded corners of the casing, consisting of longitudinal 1 and transverse 2 partitions, forming cells for cartridges 3 with an annular groove 4. In the upper plane of the casing at the intersections of partitions 1 and 2 in each cell there are made latching tabs, which in shape in an embodiment with respect to each cell can be made in the form of one fourth of a circle 5 or rectangle 6, for example, with rounded corners. Rectangle 6 can be directed by vertices that coincide with the direction of the partitions 1 and 2, or made at an angle mainly of 45 ° to them.

Packaging cartridges of small arms using the proposed liner works as follows.

Insert the cartridge 3 into the cell from the side of the upper surface of the liner body with retainer petals and move them by tilting the retainer petals as they move into the annular groove 4 of the cartridge sleeve or to a predetermined position where the retainer petals contact the conical surface of the case sleeves. In this case, the latching petals, in the first case, having got into the annular groove 4, partially straighten due to the elastic properties of the liner material and reliably hold the cartridge against displacement relative to its longitudinal axis, and in the second case, in contact with the conical surface of the sleeve body, also hold the cartridge securely from displacement. The side walls 1 and 2 of each cell hold the cartridge from shifting to the sides. After filling all the cells of the insert with cartridges, the insert is installed in the packaging box and close it.

Using the proposed liner allows you to mechanize the process of packing cartridges, in particular to mechanize the processes of installing cartridges in the cells of the liner and installing liners with cartridges in the box.

Currently, the design and technological documentation has been developed for the proposed insert for packaging small arms cartridges, an experimental batch of inserts has been manufactured, cartridges have been packaged in them, and tests have been carried out that have shown positive results that meet all packaging requirements. The cartridges during shaking, falling of the packaging boxes from a height of two meters did not change their position in the insert and did not touch each other. After removing all the cartridges from the insert, the latter was suitable for installing other cartridges in the insert.

It was decided in the first quarter of 2011 to begin the industrial use of the proposed inserts for packaging small arms cartridges.
