DESCRIPTION:
BRIEF SUMMARY
The field of the present invention is that of containers capable of accommodating a propellant charge and more particularly that of containers used in the field of large calibre or tank artillery.
In order to adjust the range of the round, it is often necessary to modify the amount of powder used for firing a projectile.
Modular containers have already been defined that are substantially cylindrical and made of a combustible material. Their rigidity makes such containers more easy to use than traditional bags of powder.
In order to reduce the space taken up by ammunition inside armoured vehicles, it may also be necessary to subdivide each round into two separate parts, one carrying the main propellant charge and the other the projectile and possibly a secondary propellant charge (such ammunition is described for example in patent GB2136929).
In any event one may consider the problem of integrating several containers.
For example it may be valuable to speed up the loading process by introducing all the containers in a single operation, for example by means of an automatic loading system.
It is then essential to integrate the containers together in order to give a degree of rigidity to the assembly.
Moreover it may prove necessary to quickly remove the charge already inserted in the chamber of a gun, and this process is made longer and more difficult if the entire charge is divided into several parts.
Patent FR9101499 describes a device for connecting containers together which comprises, first, a sliding sleeve and, secondly, automatic means of coupling positioned on a front surface of the container.
Such a system is complex and costly to manufacture.
Moreover it may or may not be necessary to link the containers together, according to operational requirements. The means proposed by FR9101499 do not allow such a choice to be made, the axial connection in all cases being provided by the automatic couplings.
Finally, the means proposed by FR9101499 are awkward to use. Thus for the sleeve to be able to slide, the radial positioning of the two containers must be exact. In fact the means of coupling are active whatever the relative radial position of the two containers. Consequently it is difficult to position the two containers and then to integrate them together.
The purpose of the present invention is to provide a container that is not affected by such drawbacks.
The invention therefore proposes a container comprising simple and inexpensive means of integrating it with a second container at one of its front surfaces.
Such a container can be connected quickly and easily to another container according to the invention, separation of the containers being equally easy.
Hence the purpose of the invention is a container intended to be integrated with a second container at one of its front surfaces, and comprising a sleeve fitted so as to slide on a first narrowed portion or neck, the said sleeve capable of sliding so as partly to cover a second narrowed portion or neck made on the second container, characterised by the fact that the sleeve carries a thread tapped on a forward end, the said thread being intended to engage on a thread integral with the second container.
According to another characteristic of the invention, the first neck has an annular collar upon which bears a shoulder machined on a rear part of the sleeve so as to immobilise the containers axially when the sleeve covers the second neck of the second container.
With advantage, the container has an inner sleeve integral with the first neck and which carries the annular collar, an inner sleeve upon which the sleeve can slide.
The purpose of the invention is also a container intended to be integrated at one of its front surfaces with another container, the said container being characterised by the fact that it comprises a second neck which is threaded, intended to accommodate a tapped and sliding sleeve carried by the other container.
This container advantageously comprises a threaded ring integral with the second neck.
