Abstract

The container (1) is filled with a charge of rapid combustion powder in the same volume as a traditional slow-burning powder charge used for long-range projectiles, and has an inner volume reducer (R) which can be differentiated visually and/or by touch from a traditional container. The container has a basically cylindrical outer casing (3), a central through channel and two end walls (4,5), and the inner volume reducers can be in the form of recesses in the end walls or cylindrical side wall of the casing. The casing can be assembled, for example, from three coaxial moulded components which are made from a cardboard charged with nitrocellulose some 3 mm thick.

Description

L'invention concerne un conteneur combustible de charge propulsive pour une munition d'artillerie de campagne.The invention relates to a propellant charge combustible container for field artillery ammunition.

D'une manière générale, une munition d'artillerie de campagne est réalisée en deux parties, l'une constituée par un projectile, par exemple du type incendiaire, explosif, éclairant, etc..., et l'autre par une charge propulsive.Generally, a field artillery ammunition is produced in two parts, one consisting of a projectile, for example of the incendiary, explosive, lighting, etc. type, and the other by a propellant charge .

La charge propulsive est le plus souvent fractionnée de manière à pouvoir ajuster la portée du projectile suivant la stratégie militaire appliquée. Il est connu de réaliser ce fractionnement sous la forme de gargousses constituées chacune d'un sac de toile renfermant une quantité de poudre propulsive, mais on voit maintenant apparaître de plus en plus un fractionnement sous la forme de conteneurs combustibles. En jouant sur le nombre des gargousses ou des conteneurs (de 1 à 6), on modifie la quantité de poudre utilisée et on règle ainsi la portée du tir.The propellant charge is most often divided so that the range of the projectile can be adjusted according to the military strategy applied. It is known to carry out this fractionation in the form of gargoyles each consisting of a canvas bag containing a quantity of propellant powder, but we now see a fractionation appearing more and more in the form of combustible containers. By varying the number of gargoyles or containers (from 1 to 6), the quantity of powder used is modified and the range of the shot is thus regulated.

Cependant, à l'heure actuelle, on recherche une certaine polyvalence des artilleries de campagne qui sont essentiellement utilisées pour des tirs de longue portée, au-delà de 15 km, afin de pouvoir les utiliser pour effectuer des tirs à courte portée sur des distances inférieures à 10 km, par exemple.However, at the moment, we are looking for a certain versatility of field artillery which is mainly used for long-range shots, beyond 15 km, in order to be able to use them to make short-range shots over distances. less than 10 km, for example.

Cette polyvalence des artilleries de campagne se heurte toutefois au problème de la nature de la poudre à utiliser car le fonctionnement de l'artillerie ne doit pas être perturbé. Pour un tir de longue portée, on utilise une poudre lente, c'est-à-dire à débit gazeux faible, mais cette poudre n'est pas adaptée à un tir de courte portée. En effet, si on réduit la quantité de poudre lente en n'utilisant que deux ou trois conteneurs par exemple, la pression qui est alors engendrée dans la chambre de l'arme au moment du tir est relativement faible et entraîne des problèmes de combustion incomplète, ce qui se traduit par la présence d'imbrûlés.This versatility of field artillery however comes up against the problem of the nature of the powder to be used because the functioning of the artillery must not be disturbed. For long-range shooting, a slow powder, that is to say with a low gas flow, is used, but this powder is not suitable for short-range shooting. Indeed, if the quantity of slow powder is reduced by using only two or three containers for example, the pressure which is then generated in the chamber of the weapon at the time of the firing is relatively low and causes problems of incomplete combustion , which results in the presence of unburnt.

Par contre, les poudres vives à débit gazeux relativement important sont parfaitement adaptées pour des tirs de courte portée, alors qu'elles ne le sont pas pour des tirs de longue portée.On the other hand, live powders with a relatively large gas flow rate are perfectly suited for short-range shots, whereas they are not suitable for long-range shots.

Des conteneurs combustibles sont par exemple décrits dans les documents WO-A-8500433 et EP-A-475 207.Combustible containers are for example described in documents WO-A-8500433 and EP-A-475 207.

Le document WO-A-8500433 décrit des modules de charge propulsive sous la forme de conteneurs combustibles remplis de poudre, avec un canal axial dans lequel est placée une charge d'allumage.WO-A-8500433 describes propellant charge modules in the form of combustible containers filled with powder, with an axial channel in which an ignition charge is placed.

Le document EP-A-475 207 décrit un conteneur combustible qui est constitué de deux parties d'enveloppe emboîtées l'une dans l'autre, avec un canal central renfermant une charge d'aide à l'allumage. On notera toutefois que la charge est une poudre lente compactée et que la surface externe du conteneur présente une aspérité susceptible de poser des problèmes lors de la phase d'alimentation de l'arme.The document EP-A-475 207 describes a combustible container which consists of two envelope parts fitted one inside the other, with a central channel containing an ignition aid charge. Note, however, that the charge is a slow compacted powder and that the external surface of the container has an asperity liable to pose problems during the feeding phase of the weapon.

Le but de l'invention est de proposer un conteneur combustible utilisable dans une artillerie de campagne pour effectuer des tirs de courte portée sans pour autant modifier le mécanisme de chargement de l'arme.The object of the invention is to provide a combustible container which can be used in field artillery to carry out short-range fire without modifying the loading mechanism of the weapon.

A cet effet, l'invention propose un conteneur combustible de charge propulsive pour une munition d'artillerie de campagne, qui est caractérisé en ce que la charge propulsive est une poudre vive, et en ce que le conteneur :

  • présente le même encombrement qu'un conteneur classique de charge propulsive à poudre lente et utilisé pour effectuer des tirs de longue portée,
  • comprend des moyens de réduction de son volume intérieur pour renfermer la quantité de poudre vive nécessaire pour que l'artillerie de campagne soit également utilisée pour effectuer des tirs de courte portée, et
  • comprend des moyens pour pouvoir le différencier visuellement et tactilement d'un conteneur classique à poudre lente.
To this end, the invention provides a combustible container of propellant charge for a field artillery ammunition, which is characterized in that the propellant charge is a live powder, and in that the container:
  • has the same size as a conventional propellant container with slow powder and used for long-range shots,
  • comprises means for reducing its internal volume to contain the quantity of live powder necessary for the field artillery to also be used for carrying out short-range fire, and
  • includes means to be able to visually and tactually differentiate it from a conventional slow powder container.

Selon une autre caractéristique de l'invention, les moyens de réduction du volume intérieur du conteneur forment également les moyens pour pouvoir différencier le conteneur d'un conteneur classique.According to another characteristic of the invention, the means for reducing the interior volume of the container also form the means to be able to differentiate the container from a conventional container.

D'une manière générale, le conteneur est constitué d'un fût central, d'une enveloppe latérale coaxiale et concentrique extérieurement au fût central, un fond et un couvercle, les moyens de réduction du volume intérieur du conteneur étant situé au niveau de son enveloppe, de son fond et/ou de son couvercle.In general, the container consists of a central barrel, a coaxial and concentric lateral envelope externally to the central barrel, a bottom and a cover, the means for reducing the interior volume of the container being located at its level. envelope, its bottom and / or its cover.

Selon une première forme de réalisation de l'invention, les moyens de réduction du volume intérieur du conteneur sont constitués par un rétreint formé au niveau de l'enveloppe du conteneur, ce rétreint étant par exemple réalisé par une réduction de diamètre de la partie centrale de l'enveloppe du conteneur.According to a first embodiment of the invention, the means for reducing the interior volume of the container are constituted by a constriction formed at the level of the envelope of the container, this constriction being for example produced by a reduction in diameter of the central part of the container shell.

Suivant un mode de réalisation du conteneur, le fond et le couvercle sont deux pièces annulaires sensiblement identiques qui sont pourvues de deux rebords circulaires interne et externe au moyen desquels ils sont emboîtés entre le fût central et l'enveloppe, cet assemblage par emboîtement étant un ajustage serré qui est éventuellement complété par une opération de collage.According to one embodiment of the container, the bottom and the cover are two substantially identical annular parts which are provided with two internal and external circular edges by means of which they are fitted between the central barrel and the casing, this fitting assembly being a tight fitting which is possibly supplemented by a gluing operation.

En variante, le fond et le couvercle du conteneur ne peuvent former qu'une seule pièce.As a variant, the bottom and the lid of the container can form only one piece.

Suivant un autre mode de réalisation, l'enveloppe du conteneur est formée de deux tronçons coaxiaux, axialement alignés l'un avec l'autre et assemblés l'un à l'autre par emboîtement à ajustement serré.According to another embodiment, the envelope of the container is formed of two coaxial sections, axially aligned with each other and assembled to one another by interlocking with close fit.

Dans cette forme de réalisation, chaque tronçon comprend une première partie cylindrique dans laquelle vient s'emboîter le fond ou le couvercle du conteneur, et une seconde partie cylindrique de diamètre réduit formant une partie du rétreint, ces première et seconde parties étant reliées l'une à l'autre par une paroi de liaison de forme globalement tronconique.In this embodiment, each section comprises a first cylindrical part into which the bottom or the lid of the container fits, and a second cylindrical part of reduced diameter forming a part of the constriction, these first and second parts being connected to the one to the other by a connecting wall of generally frustoconical shape.

Pour assurer l'assemblage entre les deux tronçons d'enveloppe, l'extrémité de la seconde partie cylindrique de diamètre réduit de l'un des tronçons de l'enveloppe présente une légère augmentation de diamètre formant une jupe dans laquelle vient s'emboîter la seconde partie cylindrique de diamètre réduit de l'autre tronçon.To ensure assembly between the two envelope sections, the end of the second cylindrical portion of reduced diameter of one of the envelope sections has a slight increase in diameter forming a skirt in which comes to fit the second cylindrical part of reduced diameter of the other section.

En variante, les deux tronçons de l'enveloppe sont sensiblement identiques. A cet effet, la seconde partie cylindrique de diamètre réduit de chaque tronçon comprend une demi-enveloppe ayant une légère augmentation de diamètre vers son extrémité libre pour former une demi-jupe dans laquelle vient s'emboîter la demi-enveloppe de l'autre tronçon qui n'est pas pourvu de la demi-jupe.Alternatively, the two sections of the envelope are substantially identical. To this end, the second cylindrical portion of reduced diameter of each section comprises a half-envelope having a slight increase in diameter towards its free end to form a half-skirt in which the half-envelope of the other section is fitted. which is not provided with the half-skirt.

Selon une seconde forme de réalisation, les moyens de réduction du volume intérieur du conteneur sont constitués par au moins une empreinte réalisée dans le fond et/ou le couvercle, cette empreinte délimitant un bossage qui fait saillie à l'intérieur du conteneur, cette empreinte étant sous la forme d'une gorge annulaire centrée autour du fût central, par exemple.According to a second embodiment, the means for reducing the interior volume of the container consist of at least one imprint made in the bottom and / or the lid, this imprint delimiting a boss which protrudes inside the container, this imprint being in the form of an annular groove centered around the central shaft, for example.

Suivant un mode de réalisation, l'enveloppe du conteneur est cylindrique, et le fond et le couvercle sont deux pièces annulaires semblables et pourvues de rebords circulaires interne et externe au moyen desquels ils sont assemblés par emboîtement entre l'enveloppe et le fût central.According to one embodiment, the envelope of the container is cylindrical, and the bottom and the cover are two similar annular parts and provided with internal and external circular edges by means of which they are assembled by interlocking between the envelope and the central barrel.

En variante, le fût, le fond et l'enveloppe du conteneur ne peuvent former qu'une seule pièce.As a variant, the barrel, the bottom and the envelope of the container can only form a single piece.

Selon une autre caractéristique de l'invention, les moyens de réduction du volume intérieur du conteneur comprennent également des cales intérieures en un matériau combustible pour caler la poudre vive sous la forme de grains, lorsque le volume intérieur du conteneur n'est que partiellement rempli.According to another characteristic of the invention, the means for reducing the interior volume of the container also include interior wedges of a combustible material for wedging the live powder in the form of grains, when the interior volume of the container is only partially filled. .

A titre d'exemple, une cale intérieure est par exemple constituée par un cylindre monté coaxialement au fût central en prenant appui contre les moyens de réduction du volume intérieur du conteneur, la poudre vive étant chargée du côté du fût central.By way of example, an inner wedge is for example constituted by a cylinder mounted coaxially with the central barrel, bearing against the means for reducing the interior volume of the container, the live powder being loaded on the side of the central barrel.

D'une manière générale, la poudre vive utilisée se présente sous la forme de grains, de sticks ou de brins pré-divisés, et le conteneur est fabriqué en un matériau combustible tel que du carton chargé de nitrocellulose avec une épaisseur de l'ordre de 3 mm.Generally, the live powder used is in the form of grains, sticks or pre-divided strands, and the container is made of a material fuel such as cardboard loaded with nitrocellulose with a thickness of the order of 3 mm.

Selon un premier avantage de l'invention, le conteneur peut être pris en charge par le dispositif de chargement automatique qui équipe les artilleries de campagne pour permettre à celles-ci d'effectuer indifféremment des tirs de longue ou de courte portée.According to a first advantage of the invention, the container can be taken care of by the automatic loading device which equips the field artillery to allow these to carry out either long or short range shots.

Selon un autre avantage de l'invention, le servant peut facilement différencier de jour comme de nuit ce type de conteneur par rapport à un conteneur de poudre lente de même encombrement qui ne présente pas des caractéristiques de forme telles que celles envisagées dans l'invention pour réduire le volume intérieur du conteneur.According to another advantage of the invention, the servant can easily differentiate day and night this type of container compared to a slow powder container of the same size which does not have shape characteristics such as those envisaged in the invention to reduce the interior volume of the container.

Selon encore un autre avantage de l'invention, le conteneur est réversible, c'est-à-dire qu'il n'y a pas lieu de distinguer une extrémité avant ou arrière avant de procéder à son chargement.According to yet another advantage of the invention, the container is reversible, that is to say that there is no need to distinguish a front or rear end before loading.

Les conteneurs à poudre vive selon l'invention et tels que schématisés sur les différentes figures présentent le même encombrement que des conteneurs classiques à poudre lente utilisés dans les munitions d'une artillerie de campagne qui effectue des tirs de longue portée, c'est-à-dire qu'ils présentent globalement les mêmes dimensions en hauteur et en diamètre extérieur que celles d'un conteneur classique pour qu'une artillerie de campagne puisse également effectuer des tirs de courte portée.The live powder containers according to the invention and as shown diagrammatically in the various figures have the same bulk as conventional slow powder containers used in the munitions of a field artillery which performs long-range shots, that is to say that is to say that they generally have the same dimensions in height and in outside diameter as those of a conventional container so that a field artillery can also carry out short-range fire.

D'une manière générale et dans tous les modes de réalisation qui vont être décrits, un conteneur 1 selon l'invention est constitué de plusieurs pièces, à savoir : un fût central 2 dont la hauteur définit ici la hauteur du conteneur, une enveloppe latérale 3 globalement cylindrique, coaxiale et concentrique extérieurement au fût 2, un couvercle 4 à une extrémité et un fond 5 à l'autre extrémité. Ces différentes pièces, une fois assemblées les unes aux autres, délimitent entre elles un volume intérieur 7 de forme annulaire et destiné à contenir de la poudre vive.In general and in all the embodiments which will be described, a container 1 according to the invention consists of several parts, namely: a central barrel 2 whose height here defines the height of the container, a lateral envelope 3 generally cylindrical, coaxial and concentric on the outside with the barrel 2, a cover 4 at one end and a bottom 5 at the other end. These different parts, once assembled to each other, delimit between them an internal volume 7 of annular shape and intended to contain live powder.

Etant donné que pour un même encombrement, ces conteneurs 1 vont être chargés d'une quantité de poudre vive inférieure à la quantité de poudre lente chargée dans un conteneur classique, le volume intérieur 7 de ces conteneurs va être réduit à l'aide de moyens dénommés ci-après moyens de réduction du volume intérieur du conteneur.Given that for the same size, these containers 1 will be loaded with an amount of live powder less than the amount of slow powder loaded in a conventional container, the internal volume 7 of these containers will be reduced using means hereinafter referred to as means of reducing the interior volume of the container.

Selon une première forme de réalisation de l'invention, les moyens de réduction du volume intérieur 7 d'un conteneur 1 sont constitués par un rétreint R formé au niveau de l'enveloppe latérale 3 du conteneur.According to a first embodiment of the invention, the means for reducing the internal volume 7 of a container 1 are constituted by a constriction R formed at the lateral envelope 3 of the container.

Selon un premier mode de réalisation illustré sur les figures 1 et 2, le fût central 2 et le fond 4 du conteneur ne forment qu'une seule pièce. Plus précisément, une extrémité du fût central 2 se prolonge radialement vers l'extérieur par une paroi de fond 8 plane et de forme annulaire. La partie périphérique externe de la paroi de fond 8 est bordée par une paroi latérale qui forme un rebord circulaire 9.According to a first embodiment illustrated in Figures 1 and 2, the central barrel 2 and the bottom 4 of the container form only one piece. More specifically, one end of the central barrel 2 is extended radially outwards by a bottom wall 8 which is flat and of annular shape. The external peripheral part of the bottom wall 8 is bordered by a side wall which forms a circular rim 9.

Le couvercle 5 est constitué par une paroi de fond 10 plane et de forme annulaire. Cette paroi de fond 10 est bordée intérieurement et extérieurement par deux parois latérales qui s'étendent d'un même côté de la paroi de fond 10 et parallèlement à l'axe du fût central 2 pour former respectivement un rebord interne circulaire 11 et un rebord externe circulaire 12. Le diamètre intérieur du rebord circulaire interne 11 est ajusté au diamètre extérieur du fût central 2, alors que le diamètre extérieur du rebord circulaire externe 12 est sensiblement égal à celui du rebord circulaire 9 du fond 4.The cover 5 is constituted by a flat bottom wall 10 and of annular shape. This bottom wall 10 is bordered internally and externally by two lateral walls which extend on the same side of the bottom wall 10 and parallel to the axis of the central shaft 2 to respectively form a circular internal rim 11 and a rim external circular 12. The internal diameter of the internal circular rim 11 is adjusted to the external diameter of the central barrel 2, while the external diameter of the external circular rim 12 is substantially equal to that of the circular rim 9 of the bottom 4.

L'enveloppe 3 est formée de deux tronçons 3a et 3b qui comprennent chacun :

  • une première partie cylindrique 15 dont le diamètre extérieur délimite le diamètre du conteneur 1 et il est égal au diamètre extérieur d'un conteneur classique à poudre lente, et dont le diamètre intérieur est sensiblement ajusté au diamètre extérieur du rebord circulaire 9 du fond 4 ou du rebord circulaire externe 12 du couvercle 5,
  • une seconde partie cylindrique 17 de diamètre réduit et qui forme une partie du rétreint R, et
  • une troisième partie de liaison 19 de forme tronconique qui relie les parties cylindriques 15 et 17.
The envelope 3 is formed of two sections 3a and 3b which each include:
  • a first cylindrical part 15, the outside diameter of which delimits the diameter of the container 1 and it is equal to the outside diameter of a conventional slow powder container, and the inside diameter of which is substantially adjusted to the outside diameter of the circular rim 9 of the bottom 4 or the outer circular rim 12 of the cover 5,
  • a second cylindrical part 17 of reduced diameter which forms part of the constriction R, and
  • a third connecting part 19 of frustoconical shape which connects the cylindrical parts 15 and 17.

Vers son extrémité libre, la seconde partie cylindrique 17 du tronçon 3a présente une augmentation de diamètre à partir d'un rebord 20 pour former une jupe 22 dont le diamètre intérieur est ajusté au diamètre extérieur de la seconde partie cylindrique 17 de l'autre tronçon 3b. En variante, la jupe 22 peut être prévue sur le tronçon 3b.Towards its free end, the second cylindrical part 17 of the section 3a has an increase in diameter from a flange 20 to form a skirt 22 whose internal diameter is adjusted to the outside diameter of the second cylindrical part 17 of the other section 3b. As a variant, the skirt 22 can be provided on the section 3b.

Le conteneur 1 comprend donc quatre pièces, en l'occurrence : le fût central 2 prolongé à une extrémité par le fond 4, deux tronçons 3a et 3b qui forment l'enveloppe 3, et le couvercle 5. Ces quatre pièces sont fabriquées par moulage et leur assemblage s'effectue comme décrit ci-après.The container 1 therefore comprises four parts, in this case: the central barrel 2 extended at one end by the bottom 4, two sections 3a and 3b which form the envelope 3, and the cover 5. These four parts are produced by molding and their assembly is carried out as described below.

Le tronçon 3a de l'enveloppe 3 du conteneur est rapporté autour du fût central 2 de manière à ce que le rebord 9 du fond 4 vienne s'emboîter par un ajustement serré dans la partie cylindrique 15 du tronçon 3a.The section 3a of the envelope 3 of the container is attached around the central barrel 2 so that the rim 9 of the bottom 4 comes to fit by a tight fit in the cylindrical part 15 of the section 3a.

D'une manière analogue, le tronçon 3b de l'enveloppe 3 du conteneur est rapporté autour du fût central 2 de manière à ce que sa partie cylindrique 17 de diamètre réduit vienne s'emboîter par un ajustement serré dans la jupe 22 du tronçon d'enveloppe 3a précédemment assemblé au fond 4 du conteneur.In an analogous manner, the section 3b of the envelope 3 of the container is attached around the central barrel 2 so that its cylindrical part 17 of reduced diameter comes to fit by a tight fit in the skirt 22 of the section d envelope 3a previously assembled at the bottom 4 of the container.

Le fût central 2, le fond 4 et l'enveloppe 3 du conteneur ainsi assemblés, délimitent entre eux le volume intérieur 7 du conteneur dont la capacité de charge, pour un encombrement donné du conteneur, est fonction de la profondeur du rétreint R qui est formé dans l'enveloppe 3 et de la forme donnée à la partie de liaison 19 qui réunit les deux tronçons d'enveloppe 3a et 3b.The central barrel 2, the bottom 4 and the casing 3 of the container thus assembled, delimit between them the interior volume 7 of the container, the load capacity of which, for a given size of the container, is a function of the depth of the constriction R which is formed in the envelope 3 and of the shape given to the connecting part 19 which joins the two envelope sections 3a and 3b.

Le volume intérieur 7 du conteneur est chargé de poudre vive selon des modalités qui seront précisées plus loin, et est ensuite fermé au moyen du couvercle 5 qui vient s'emboîter avec un ajustement serré entre le fût central 2 et le tronçon d'enveloppe 3b au moyen de ses deux rebords circulaires interne 11 et externe 12.The interior volume 7 of the container is loaded with live powder according to methods which will be specified below, and is then closed by means of the cover 5 which comes to fit together with a tight fit between the central barrel 2 and the envelope section 3b by means of its two circular edges internal 11 and external 12.

Les opérations d'assemblage des différentes pièces du conteneur 1 peuvent être améliorées par des opérations de collage, connues en soi.The assembly operations of the different parts of the container 1 can be improved by bonding operations, known per se.

Un second mode de réalisation illustré sur les figures 3 et 4 diffère du précédent essentiellement dans les moyens utilisés pour réaliser l'assemblage entre les deux tronçons d'enveloppe 3a et 3b.A second embodiment illustrated in Figures 3 and 4 differs from the previous essentially in the means used to achieve the assembly between the two envelope sections 3a and 3b.

Sur la figure 3, la partie cylindrique 17 de diamètre réduit du tronçon d'enveloppe 3b comporte une jupe 24 qui ne s'étend que sur une demi-circonférence et, d'une façon symétrique, la partie cylindrique 17 de diamètre réduit de l'autre tronçon 3a comporte également une demi-jupe 24 qui ne s'étend que sur une demi-circonférence. Ainsi, les deux tronçons d'enveloppe 3a et 3b ont des formes identiques mais chacun d'eux présente une dissymétrie par rapport à l'axe du fût central 2, disymétrie qui disparaît lorsque les deux tronçons d'enveloppe 3a et 3b sont assemblés l'un à l'autre par emboîtement. Un tel assemblage permet de réduire le nombre de pièces constituant un conteneur.In FIG. 3, the cylindrical part 17 of reduced diameter of the envelope section 3b comprises a skirt 24 which extends only over a half-circumference and, in a way symmetrical, the cylindrical part 17 of reduced diameter of the other section 3a also comprises a half-skirt 24 which extends only over a half-circumference. Thus, the two envelope sections 3a and 3b have identical shapes but each of them has an asymmetry with respect to the axis of the central shaft 2, asymmetry which disappears when the two envelope sections 3a and 3b are assembled. 'to each other by interlocking. Such an assembly makes it possible to reduce the number of parts constituting a container.

Selon un troisième mode de réalisation illustré à la figure 5, l'enveloppe 3 du conteneur est formée en une seule pièce qui comprend une première partie cylindrique 15 à chaque extrémité, une partie cylindrique centrale 17 de diamètre réduit et deux parois de liaison 19 globalement tronconiques entre les deux parties 15 et 17. Dans ce mode de réalisation, le fond 4 est dissocié du fût central 2, c'est-à-dire que le fond 4 est sensiblement identique au couvercle 5 et présente un rebord circulaire interne 11 et rebord circulaire externe 12 au moyen desquels le fond 4 vient s'emboîter entre le fût central 2 et l'enveloppe 3.According to a third embodiment illustrated in FIG. 5, the envelope 3 of the container is formed in a single piece which comprises a first cylindrical part 15 at each end, a central cylindrical part 17 of reduced diameter and two connecting walls 19 overall frustoconical between the two parts 15 and 17. In this embodiment, the bottom 4 is dissociated from the central barrel 2, that is to say that the bottom 4 is substantially identical to the cover 5 and has an internal circular rim 11 and external circular rim 12 by means of which the bottom 4 fits between the central barrel 2 and the casing 3.

Une fois le fond 4 assemblé au fût central 2 et à l'enveloppe 3, on procède au remplissage du volume intérieur 7 du conteneur par de la poudre vive, et on rapporte ensuite le couvercle 5, comme précédemment.Once the bottom 4 has been assembled to the central barrel 2 and to the casing 3, the interior volume 7 of the container is filled with live powder, and the cover 5 is then brought back, as before.

Dans les trois modes de réalisation précédemment décrits, le rétreint R formé par une réduction de diamètre de la partie centrale de l'enveloppe 3, donne au conteneur une forme de bobine qui permet de le différencier immédiatement aussi bien visuellement que tactilement, par rapport à un conteneur à poudre lente de même encombrement dont l'enveloppe latérale est parfaitement cylindrique.In the three embodiments described above, the constriction R formed by a reduction in diameter of the central part of the envelope 3, gives the container a coil shape which makes it possible to immediately differentiate it both visually and tactile, compared to a slow powder container of the same size, the lateral envelope of which is perfectly cylindrical.

Suivant une deuxième forme de réalisation de l'invention, les moyens de réduction du volume intérieur 7 du conteneur 1 sont constitués par au moins une empreinte E réalisée dans le fond et/ou le couvercle du conteneur.According to a second embodiment of the invention, the means for reducing the interior volume 7 of the container 1 consist of at least one cavity E made in the bottom and / or the cover of the container.

Selon le quatrième mode de réalisation illustré sur la figure 6, le conteneur 1 comprend un fût central 2, une enveloppe latérale cylindrique 3 coaxiale et concentrique extérieurement au fût 2, un couvercle 5 avec une paroi de fond 10 annulaire bordée de chaque côté par un rebord circulaire interne 11 et un rebord circulaire externe 12, et un fond 4 avec une paroi de fond 8 annulaire bordée de chaque côté par un rebord circulaire interne 11 et un rebord circulaire externe 12. Ces quatre pièces sont assemblées par emboîtement comme précédemment.According to the fourth embodiment illustrated in FIG. 6, the container 1 comprises a central barrel 2, a cylindrical lateral envelope 3 coaxial and concentric externally with the barrel 2, a cover 5 with a wall of annular bottom 10 bordered on each side by an internal circular rim 11 and an external circular rim 12, and a bottom 4 with an annular bottom wall 8 bordered on each side by an internal circular rim 11 and an external circular rim 12. These four parts are assembled by interlocking as previously.

Une empreinte E est réalisée dans la paroi de fond 8 du fond 4 et dans la paroi de fond 10 du couvercle 5. Chaque empreinte E sous la forme d'une gorge annulaire 25 qui délimite un bossage qui fait saillie à l'intérieur du volume 7 du conteneur.An imprint E is made in the bottom wall 8 of the bottom 4 and in the bottom wall 10 of the cover 5. Each imprint E in the form of an annular groove 25 which delimits a boss which projects inside the volume 7 of the container.

Selon le mode de réalisation illustré aux figures 7 et 8, le conteneur 1 ne diffère de celui représenté à la figure 6 que par le fait que le fût central 2, la paroi de fond 4 et l'enveloppe latérale cylindrique 3 ne forment qu'une seule pièce pour limiter à deux le nombre de pièces à assembler. En variante, ce nombre pourrait être de trois en séparant l'enveloppe 3 et le fond 4 du conteneur.According to the embodiment illustrated in FIGS. 7 and 8, the container 1 differs from that shown in FIG. 6 only by the fact that the central barrel 2, the bottom wall 4 and the cylindrical lateral envelope 3 only form one piece to limit the number of pieces to be assembled to two. As a variant, this number could be three by separating the envelope 3 and the bottom 4 of the container.

Dans ces deux derniers modes de réalisation, le volume intérieur 7 du conteneur a une capacité de charge, pour un encombrement donné du conteneur, qui est fonction du nombre, de la forme et de la profondeur des empreintes E. Ces dernières donnent au conteneur une forme de couronne qui permet de le différencier aussi bien visuellement que tactilement, par rapport à un conteneur à poudre lente dont le fond et/ou le couvercle ne présentent pas de telles empreintes.In these last two embodiments, the interior volume 7 of the container has a load capacity, for a given size of the container, which is a function of the number, the shape and the depth of the imprints E. These latter give the container a crown shape which makes it possible to differentiate it visually as well as tactile, compared to a container with slow powder whose bottom and / or lid do not present such imprints.

Dans tous les modes de réalisation, la poudre vive qui est chargée dans le conteneur peut se présenter sous la forme de grains, de sticks ou de brins pré-divisés, et le conteneur est fabriqué avantageusement en un matériau combustible comme du carton chargé de nitrocellulose, par exemple.In all the embodiments, the live powder which is loaded into the container can be in the form of grains, sticks or pre-divided strands, and the container is advantageously made of a combustible material such as cardboard loaded with nitrocellulose. , for example.

Plus précisément, en ce qui concerne le chargement de la poudre vive sous la forme de grains, le volume intérieur 7 du conteneur 1 peut être complètement ou partiellement rempli. Au contraire d'un remplissage complet, comme illustré sur la figure 1, un remplissage partiel nécessite la présence de moyens complémentaires de réduction du volume intérieur 7 du conteneur 1 pour caler les grains de poudre g et assurer la cohésion du conteneur 1. Comme illustré aux figures 5 et 6, ces moyens sont constitués par au moins une cale intérieure 30 en un matériau combustible, cette cale 30 étant montée à l'intérieur du conteneur 1 de manière à ce que les grains de poudre g soit de préférence au contact du fût central 2. La cale 30 est par exemple un tube monté coaxialement au fût 2 en prenant appui contre la partie cylindrique 17 de diamètre réduit de l'enveloppe 3 du conteneur 1 (figure 5) ou contre la paroi latérale de la gorge 25 (figure 6). En outre, des cales peuvent s'avérer nécessaires dans le cas où, pour un même conteneur et pour les mêmes caractéristiques de poudre, la masse et le volume de cette poudre peuvent être différents suivant les lots de fabrication.More precisely, as regards the loading of the live powder in the form of grains, the internal volume 7 of the container 1 can be completely or partially filled. Unlike complete filling, as illustrated in FIG. 1, partial filling requires the presence of additional means for reducing the internal volume 7 of the container 1 for wedging the grains of powder g and ensuring the cohesion of the container 1. As illustrated in FIGS. 5 and 6, these means consist of at least one internal wedge 30 made of a combustible material, this wedge 30 being mounted inside the container 1 so that the powder grains g is preferably in contact with the central barrel 2. The wedge 30 is for example a tube mounted coaxially with the barrel 2 by bearing against the cylindrical part 17 of diameter reduced from the casing 3 of the container 1 (Figure 5) or against the side wall of the groove 25 (Figure 6). In addition, shims may prove to be necessary in the case where, for the same container and for the same powder characteristics, the mass and the volume of this powder may be different according to the production batches.

Par contre, lorsque la poudre vive est sous la forme de sticks, c'est-à-dire de la poudre agglomérée sous la forme de cylindres 32 qui sont tronçonnés à la longueur désirée, des cales intérieures ne sont pas nécessaires. En effet, ces cylindres 32 sont montés parallèlement au fût central 2 en prenant directement appui contre ce dernier et la partie cylindrique 17 de diamètre de l'enveloppe 3 du conteneur 1 ou la paroi latérale de la gorge 25 (figure 7).On the other hand, when the live powder is in the form of sticks, that is to say agglomerated powder in the form of cylinders 32 which are cut to the desired length, internal shims are not necessary. Indeed, these cylinders 32 are mounted parallel to the central barrel 2 by pressing directly against the latter and the cylindrical part 17 of diameter of the envelope 3 of the container 1 or the side wall of the groove 25 (Figure 7).

D'une manière générale, le fût central 2 du conteneur est destiné à contenir une charge d'allumage, d'une façon connue en soi, et c'est pour cette raison que, dans le cas de la présence de cales intérieures 30, le chargement de poudre est avantageusement situé du côté du fût central 2 du conteneur 1. La hauteur des rebords circulaires du fond 4 et du couvercle 5 est ajustée de manière à conférer au conteneur une rigidité ou robustesse suffisante, et le conteneur est parfaitement réversible, c'est-à-dire qu'il peut être indifféremment chargé par une extrémité (côté fond) ou l'autre extrémité (côté couvercle).In general, the central barrel 2 of the container is intended to contain an ignition charge, in a manner known per se, and it is for this reason that, in the case of the presence of internal shims 30, the powder load is advantageously located on the side of the central barrel 2 of the container 1. The height of the circular edges of the bottom 4 and of the cover 5 is adjusted so as to give the container sufficient rigidity or robustness, and the container is perfectly reversible, that is to say, it can be indifferently loaded by one end (bottom side) or the other end (cover side).
