Description

  The present invention relates to an ammunition container that is used as a packing container for an ammunition for a cannon or a gun.

  Generally, metal ammunition containers are used as packing containers that have a certain level of strength and airtightness when transporting or storing ammunition for gun shells or ammunition for artillery. . However, since the conventional ammunition container is cylindrical, if the ammunition container is placed on the ground, it may roll carelessly. In addition, when storing ammunition containers in an ammunition storage etc. or temporarily leaving them outdoors during exercises, multiple ammunition containers are often piled up. Since stacking piles collapses by simply stacking containers for use, it was necessary to stop both ends of the stacked piles with stoppers. In addition, when stacking cylindrical ammunition containers in this way, since they can only be stacked in a pyramid shape, there is also a problem that the space utilization efficiency (the number of storage per unit space) is poor.

  Therefore, Patent Document 1 below has been proposed as a solution to such a problem. Specifically, a pallet having a plurality of grooves on both the front and back sides that match the concavo-convex portions of the ammunition container is used, and a plurality of ammunition containers are placed in parallel on the pallet. This prevents the cylindrical ammunition container from inadvertently rolling. In addition, by stacking a plurality of pallets vertically, it is possible to stack ammunition containers without using a stopper. At this time, the number of parallel lines at each stage is the same, and the stacked mountains are rectangular, which is advantageous for space utilization efficiency.

  However, in Patent Document 1, a pallet must be used when storing an ammunition container. This increases the cost for the pallet. In addition, when the ammunition container is large and difficult to carry, it may be carried while rolling on the ground, but in that case, it takes time and effort to remove the ammunition container from the pallet. In addition, when all the stored ammunition and the like have been used, the pallet remains in addition to the empty ammunition container.

  In order to solve this problem, it can be considered that the cross-sectional shape of the ammunition container is simply a polygon such as a triangle or a quadrangle. However, in the case of a triangle or a quadrangle, it is effective for preventing rolling, but since the angle of each corner (the angle between adjacent sides) is small, it is difficult to transport the ammunition container while rolling. If each corner is chamfered slightly, it will be easy to roll to some extent, but it will not lead to a fundamental solution. On the other hand, if it is more than a decagon, it becomes close to a circle, so that the rolling prevention effect is reduced.

  Therefore, the present invention solves the above-mentioned problem and does not roll easily even when placed on the ground, but can be rolled on the ground relatively easily during transportation, and without using a stopper or a pallet. Another object of the present invention is to provide a container for ammunition that can be piled up efficiently using space.

  As a means for that purpose, the ammunition container of the present invention has a bottomed cylindrical container main body and a rim provided so as to surround the outer periphery of the container main body at both axial ends of the container main body. In addition, at least one of the outer rims (the cross-sectional shape perpendicular to the axial direction of the container body) of the rims provided at both ends is an octagon. When only one of the rims provided at both ends is an octagon, the outer periphery of the other rim may be circular.

  If a rim is provided on the outer peripheral surface of the container body, the strength of the ammunition container is increased. Therefore, even if the ammunition container is accidentally dropped, the container main body is not easily deformed or lost, and thus the internal ammunition and the like can be protected accurately from the drop impact. Further, it is possible to prevent ammunition or the like from being removed from the container body as the container body is deformed. When the ammunition container is placed on the ground or stacked, the rim serves as a fulcrum. In addition, since the outer peripheral shape of at least one rim is an octagon, even if the ammunition container is placed on the ground in a lying state, it does not roll easily. Therefore, it can be stably placed even on an inclined surface. On the other hand, in the case of an octagon, the angle of each corner (the angle between adjacent sides) is obtuse, so if the ammunition container is large and difficult to carry, it is relatively easy to move on the ground. It can be transported while rolling. When rolling on the ground, it is basically preferable to roll with the other end side as a fulcrum while lifting one end side in the axial direction, but it is also possible to roll while lying down. Moreover, by stacking the sides of the octagon so that they are attached to each other during storage, a plurality of ammunition containers can be stably stacked without using a stopper, a pallet, or the like as in the prior art. At this time, it is not necessary to reduce the number as the upper level in the stacked mountains, so that the space utilization efficiency (the number of storage per unit space) is also good. If only one of the rims provided at both ends of the container body in the axial direction is octagonal, it can be rolled and transported more easily if the circular rim side is a fulcrum while the octagonal rim side is lifted. be able to.

  As described above, there is a specific effect by making only one rim an octagon, but it is also preferable that the outer peripheral shape of both rims be an octagon. In this case, the imaginary line connecting the corners of both rims is parallel to the central axis of the container body. That is, the phases of both rims are kept the same. As a result, the ammunition container is stably supported at both axial ends of the container body, so that inadvertent rolling can be prevented more reliably and stacking stability is also increased.

  In addition, it is preferable to provide an rim having an octagonal outer peripheral shape at the axially intermediate portion of the container body. In the present invention, the “axially intermediate portion” means that it is provided between the rims at both ends, and is located not only at the axially central portion but also at a position closer to the end portion deviated from the axially central portion. Including the case where it is provided. Also in this case, the imaginary line connecting the corner of the octagonal rim provided at the axial end of the container body and the corner of the octagonal rim provided at the axially intermediate portion has the same phase. Parallel to the central axis of the main body. According to this, since the container for ammunition is stably supported also in the axial direction intermediate part, inadvertent rolling can be prevented more reliably, and stacking stability is further improved. This effect is particularly great when only one rim provided at the end is an octagon.

  In addition, it is preferable that all the rims have a handle shape in which one side surface is recessed toward the other surface side. Accordingly, the ammunition container can be easily carried while grasping the rim. This effect is particularly great when the ammunition container is relatively long.

  According to the present invention, the rim having an octagonal outer peripheral shape is provided on the outer peripheral surface of the container main body so that it does not roll easily even when the ammunition container is placed on the ground. Can be rolled. Moreover, it is possible to stack a plurality of ammunition containers with high space utilization efficiency without using a stopper or a pallet.

Example 1
In the following, typical examples of the present invention will be described. As shown in FIG. 1, an ammunition container 1 includes a bottomed cylindrical container body 10 and reinforcing rims 11, 12, 3 provided at three axial end portions and an intermediate part of the container body 10. 13 and a lid 15 for sealing the opening of the container body 10.

  The material of the container body 10 is not particularly limited as long as the container body 10 has a strength that can store and store the projectile or ammunition. For example, metal, plastic, fiber reinforced plastic, resin-impregnated paper, etc. can be used. Among them, metal and fiber reinforced plastic are preferable in terms of having good rigidity, but plastic or resin-impregnated paper may be used because reinforcing rims 11, 12, and 13 are provided. The metal is not particularly limited as long as it is a metal conventionally used in this type of ammunition container, and for example, steel, aluminum alloy, copper alloy and the like can be used. Among these, steel is preferable from the viewpoint of strength.

  The lid 15 is cup-shaped, and the material is not particularly limited as long as the inside of the ammunition container 1 can be sealed. For example, as with the container body 10, it can be made of metal, plastic, fiber-reinforced plastic, resin-impregnated paper, or rubber. The lid 15 is fitted into the opening of the container body 10 by press fitting.

  The rim 11 provided at the opening end of the container body 10, the rim 12 provided at the bottom end, and the rim 13 provided in the axial intermediate portion (axial central portion in this embodiment) It is provided so as to surround the entire circumference of the main body 10, and the outer peripheral shape (cross-sectional shape orthogonal to the axial direction of the container main body 10) of each rim 11, 12, 13 is a regular octagon. The phases of the rims 11, 12, and 13 are the same, and the imaginary line that connects the corners of the rims 11, 12, and 13 is parallel to the central axis of the container body 10. Moreover, the diameter of the virtual circle circumscribing each rim 11, 12, 13 is also the same. The rims 11, 12, and 13 can be made of metal, plastic, fiber reinforced plastic, resin-impregnated paper, or rubber, like the container body 10. Among these, since the rim is a reinforcing member for the container body 10, it is preferable that the rim is made of metal, hard plastic, fiber-reinforced plastic, or hard rubber. Each rim 11, 12, 13 is joined to the outer peripheral surface of the container body 10 by welding, screwing, adhesion, engagement, or the like. Each of the rims 11, 12, and 13 is formed by drawing, and has a handle shape in which one side surface is recessed on the other surface side (see FIG. 2).

  As shown in FIG. 2, in the ammunition container 1, a plurality of bullet gun firing charges, artillery ammunition and the like are stored in a state of being arranged in series. In FIG. 2, the state which accommodated the projectile charge 30 is shown. As the propellant used for the propellant 30, a single base propellant, a double base propellant, a triple base propellant, a multi-base propellant and the like are used. The propellant 30 is obtained by loading a granular propellant inside a burnout case made by molding a mixture of kraft pulp and nitrocellulose. Reference numeral 31 is a foamed rubber cushion material disposed at both ends of the module. Reference numeral 33 denotes a storage bag that wraps all the propellant charges 30 and the cushion materials 31 at both ends and modularizes them.

  When the ammunition container 1 is stored in an ammunition cabinet or the like, a plurality of ammunition containers 1 are stacked as shown in FIG. At this time, the octagonal rims 11, 12, and 13 serve as fulcrums, so that each ammunition container 1 does not roll and each side of the rims 11, 12, and 13 is lined with each other. By contacting, it can be piled up stably. Therefore, the stopper which prevents the collapse | stacking of the pile which piled up is unnecessary. Moreover, since it is not necessary to reduce the number so that it goes to the upper stage, it is advantageous also for space utilization efficiency.

  In the case of using the projectile charge 30, the ammunition container 1 is taken out from the stacked mountain and transported to a necessary place. At this time, it can be easily carried by grasping any two of the rims 11, 12, and 13 having a handle shape. Moreover, when the weight of the ammunition container 1 is large, it can be transported while rolling on the ground in a state where one end (the rim 11 side or the rim 13 side) is lifted or laid down. At this time, since each rim 11, 12, 13 is an octagon, it can be rolled relatively easily.

(Example 2)
FIG. 4 shows a second embodiment of the present invention. In the first embodiment, the rims 11 and 12 at both ends are both octagonal, but either one may be octagonal and the other may be circular. For example, in the second embodiment shown in FIG. 4, the rim 14 at the bottom end is circular. According to this, if the circular rim 14 side is used as a fulcrum while the octagonal rim 11 side is lifted, it can be easily rolled and transported. Alternatively, the rim at the opening side end can be circular.

(Modification)
As mentioned above, although the typical Example of this invention was described, a various deformation | transformation is possible in the range which is not restricted to this but does not deviate from the summary of this invention. For example, the cross-sectional shape of the container main body 10 may be a polygonal shape depending on the outer peripheral shape of a gun cannon firing charge or a gun gun ammunition. The lid 15 may be screwed together as well as press-fitted.

  The rim 13 at the intermediate portion in the axial direction is not necessarily provided. The rim 13 is not limited to the central portion in the axial direction, and can be provided at a position closer to one of the end portions. In addition, a plurality of rims can be provided in the middle portion of the container body 10 in the axial direction.
