Abstract
Description
Le domaine technique de l'invention est celui des dispositifs permettantThe technical field of the invention is that of devices enabling
la fermeture d'un tube en carton et notamment la fermeture d'un conteneur tubulaire pouvant recevoir une munition. the closure of a cardboard tube and in particular the closure of a tubular container capable of receiving a munition.
Il a été proposé( notamment par le brevet GB102465, de réaliser des couvercles de fermetures de tubes de carton dans lesquels le couvercle porte un taraudage qui coopère avec un filetage réalisé sur une extrémité du tube. It has been proposed (in particular by the patent GB102465) to make closures for closures of cardboard tubes in which the cover carries a tapping which cooperates with a thread made on one end of the tube.
Cependant une telle solution présente l'inconvénient 10 d'être fragile. Le carton est soumis au cisaillement et le filetage risque donc de se dégrader. However, such a solution has the disadvantage of being fragile. The cardboard is sheared and the thread may be degraded.
De plus ce mode de liaison présente un niveau d'étanchéité insuffisant. La liaison filetée n'arrête pas suffisamment l'entrée de l'humidité externe et l'étanchéité risque par ailleurs de se dégrader au fil du temps. In addition, this connection mode has an insufficient level of sealing. The threaded connection does not stop the entry of the external moisture sufficiently and the seal may also degrade over time.
C'est le but de l'invention que de proposer un dispositif de fermeture permettant de pallier de tels inconvénients. It is the object of the invention to provide a closure device for overcoming such disadvantages.
Le dispositif de fermeture selon l'invention assure ainsi une fermeture à la fois sûre, robuste et étanche. Par ailleurs le dispositif selon l'invention autorise des ouvertures et fermetures multiples sans qu'il y ait dégradation, ni de la solidité de la liaison, ni de l'étanchéité. The closure device according to the invention thus ensures a closure that is both safe, robust and watertight. Furthermore the device according to the invention allows multiple openings and closures without degradation, or the strength of the connection, or sealing.
Ainsi l'invention a pour objet un dispositif de fermeture pour un tube en carton, dispositif caractérisé en ce qu'il comporte au moins une bague destinée à être positionnée à une extrémité du tube en carton, bague comportant des moyens assurant sa solidarisation d'avec le tube et présentant un profil d'accrochage destiné à recevoir un couvercle de fermeture. Thus, the subject of the invention is a closure device for a cardboard tube, characterized in that it comprises at least one ring intended to be positioned at one end of the cardboard tube, the ring comprising means ensuring its joining together. with the tube and having a hooking profile for receiving a closure lid.
Selon une caractéristique de l'invention, la bague comporte une cavité annulaire ayant une largeur légèrement supérieure à l'épaisseur du tube en carton, cavité destinée à recevoir une extrémité du tube en carton. According to one characteristic of the invention, the ring comprises an annular cavity having a width slightly greater than the thickness of the cardboard tube, a cavity intended to receive one end of the cardboard tube.
Avantageusement la bague pourra porter un profil fileté au niveau d'une surface externe. Advantageously, the ring may carry a threaded profile at an external surface.
La bague pourra porter une extrémité amincie sur la surface externe de laquelle sera réalisée au moins une gorge circulaire destinée à recevoir un joint d'étanchéité. The ring may carry a thinned end on the outer surface of which will be made at least one circular groove for receiving a seal.
Les moyens assurant la solidarisation de la bague et du tube pourront comprendre au moins une couche de colle. The means ensuring the fastening of the ring and the tube may comprise at least one adhesive layer.
Avantageusement le couvercle pourra comporter un profil interne conique destiné à venir coopérer avec le joint d'étanchéité de la bague. Advantageously, the lid may comprise a conical inner profile intended to cooperate with the seal ring.
Le couvercle pourra comporter un sillon circulaire interne à l'intérieur duquel se positionnera l'extrémité amincie de la bague. The cover may include an internal circular groove inside which will be positioned the thin end of the ring.
La bague pourra être réalisée en matière plastique. The ring can be made of plastic.
L'invention sera mieux comprise à la lecture de la description d'un mode particulier de réalisation, description faite en référence au dessin annexé qui représente en coupe longitudinale partielle un dispositif de fermeture selon l'invention. The invention will be better understood on reading the description of a particular embodiment, description made with reference to the accompanying drawing which shows in partial longitudinal section a closure device according to the invention.
En se reportant au dessin annexé, un dispositif de fermeture 1 selon l'invention est destiné à obturer un tube en carton 2 dont seule une extrémité est représentée ici. Ce tube est ici un conteneur renfermant une munition 12 maintenue par des moyens de calage 13,14 qui ne font pas l'objet de la présente invention et qu'il n'est donc pas nécessaire de décrire en détails. Referring to the accompanying drawing, a closure device 1 according to the invention is intended to close a cardboard tube 2, only one end is shown here. This tube is here a container containing a munition 12 held by setting means 13,14 which are not the subject of the present invention and it is not necessary to describe in detail.
Ce dispositif comprend une bague 3 qui est positionnée à une extrémité du tube 2. This device comprises a ring 3 which is positioned at one end of the tube 2.
La bague est réalisée ici en matière plastique mais tout 30 autre matériau plus résistant que le carton pourrait être envisagé, par exemple le métal. The ring is made here of plastic material but any other material more resistant than the cardboard could be envisaged, for example the metal.
Cette bague comporte une cavité annulaire 4 délimitée par deux cloisons cylindriques coaxiales 5a et 5b. La largeur de la cavité 4 est légèrement supérieure à l'épaisseur du tube en carton 2 pour permettre le montage de celui ci. This ring comprises an annular cavity 4 delimited by two coaxial cylindrical partitions 5a and 5b. The width of the cavity 4 is slightly greater than the thickness of the cardboard tube 2 to allow the assembly thereof.
La bague 3 est rendue solidaire du tube 2 par collage. On disposera une couche de colle entre l'extrémité du tube 2 et le fond de la cavité 4 et/ou entre le tube 2 et les cloisons 5a, 5b. The ring 3 is secured to the tube 2 by gluing. There will be a layer of adhesive between the end of the tube 2 and the bottom of the cavity 4 and / or between the tube 2 and the partitions 5a, 5b.
Il serait possible de compléter la liaison bague / tube en prévoyant des indentations ou un moletage sur l'une et/ou l'autre des cloisons 5a, 5b. La bague 3 protège ainsi l'extrémité du tube de carton 2 et empêche notamment l'humidité de pénétrer dans le matériau du tube au niveau de l'extrémité de celui ci. Un vernis d'étanchéité pourra par ailleurs recouvrir la paroi cylindrique externe du tube 2. It would be possible to complete the ring / tube connection by providing indentations or knurling on one and / or the other of the partitions 5a, 5b. The ring 3 thus protects the end of the cardboard tube 2 and particularly prevents moisture from entering the material of the tube at the end thereof. A sealing varnish may also cover the outer cylindrical wall of the tube 2.
La bague 3 comporte au niveau de sa cloison externe 5b un profil fileté 6 qui permet la fixation d'un couvercle de fermeture 7 portant un taraudage complémentaire. The ring 3 comprises at its outer wall 5b a threaded profile 6 which allows the attachment of a closure cover 7 carrying a complementary thread.
Le taraudage et le filetage représentés ici sont à profil "artillerie", c'est à dire dans lequel chaque dent comporte un flanc perpendiculaire à l'axe de vissage. Tout autre type de filetage pourrait bien entendu être utilisé. The tapping and threading shown here are "artillery" profile, that is to say in which each tooth has a flank perpendicular to the screw axis. Any other type of thread could of course be used.
Selon une autre caractéristique de l'invention, la bague 3 comporte une extrémité amincie 3a sur la surface externe de laquelle est réalisée une gorge circulaire 8 destinée à recevoir un joint d'étanchéité torique 9. According to another characteristic of the invention, the ring 3 comprises a thinned end 3a on the outer surface of which is formed a circular groove 8 intended to receive an O-ring seal 9.
Par ailleurs le couvercle 7 comporte un profil interne conique 10 qui est destiné à venir en contact avec le joint d'étanchéité 9 lors du vissage du couvercle 7. In addition, the cover 7 has a conical internal profile 10 which is intended to come into contact with the seal 9 when the cover 7 is screwed on.
Le couvercle comporte enfin un sillon circulaire interne 11 à l'intérieur duquel se positionne l'extrémité amincie 3a 30 de la bague 3. The cover finally has an internal circular groove 11 inside which is positioned the thinned end 3a 30 of the ring 3.
Le couvercle 7 est manipulé à l'aide d'une poignée 7a. Lors du vissage du couvercle 7 sur la bague 3, le profil conique 10 vient comprimer le joint torique 9, ce qui assure l'étanchéité tout en créant un couple de frottement qui évite un dévissage automatique comme suite aux vibrations éventuelles subies ultérieurement par le conteneur. The lid 7 is manipulated using a handle 7a. When the cover 7 is screwed onto the ring 3, the conical profile 10 compresses the O-ring 9, which ensures the seal while creating a friction torque which avoids an automatic unscrewing as a result of any vibrations subsequently suffered by the container. .
Par ailleurs en position vissée, l'extrémité amincie 3a de la bague 3 se positionne à l'intérieur du sillon interne 11 du couvercle 7. Une telle disposition assure guidage et centrage du couvercle 7 lors du montage. Furthermore in the screwed position, the thinned end 3a of the ring 3 is positioned inside the internal groove 11 of the cover 7. Such an arrangement ensures guiding and centering of the cover 7 during assembly.
La cloison lla du couvercle 7 délimitant partiellement le sillon 11 permet également de positionner et fixer (par collage) les moyens de calage 14 solidaires du couvercle 7. The partition 11a of the cover 7 partially delimiting the groove 11 also makes it possible to position and fix (by gluing) the wedging means 14 integral with the cover 7.
Ces moyens de calage 14 comprennent, comme cela est visible sur la figure, un tube de carton 15 qui maintient des cales de mousse 16 et 17. These wedging means 14 comprise, as can be seen in the figure, a cardboard tube 15 which holds foam shims 16 and 17.
Le dispositif selon l'invention est très robuste et tolère les ouvertures et fermetures multiples sans dégradation du tube en carton 2. Il est particulièrement bien adapté à la fermeture de conteneurs pour munitions en raison de la qualité de l'étanchéité assurée. The device according to the invention is very robust and tolerates multiple openings and closures without degradation of the cardboard tube 2. It is particularly well suited to the closure of ammunition containers because of the quality of the seal provided.
Par ailleurs la résistance mécanique et la tenue du carton à l'humidité se trouvent améliorées par la bague 3 qui 20 protège l'extrémité du tube 2. Moreover, the mechanical strength and the resistance of the cardboard to humidity are improved by the ring 3 which protects the end of the tube 2.
Le dispositif selon l'invention peut bien entendu être mis en oeuvre pour d'autres types de tubes ou conteneurs. The device according to the invention can of course be implemented for other types of tubes or containers.
Diverses variantes sont possibles sans sortir du cadre de l'invention. Il est ainsi possible de remplacer le filetage par un autre type de profil d'accrochage entre la bague et le couvercle: encliquetage, clipsage, fermeture à baïonnette... Various variants are possible without departing from the scope of the invention. It is thus possible to replace the threading with another type of fastening profile between the ring and the cover: snap-fastening, clipping, bayonet closing, etc.
On pourrait également prévoir un autre moyen de liaison entre la bague 3 et le couvercle 7, par exemple un fil de plombage de sécurité reliant deux pattes (non représentées) l'une solidaire du couvercle 7 et l'autre solidaire de la bague 3. One could also provide another means of connection between the ring 3 and the cover 7, for example a safety sealing wire connecting two tabs (not shown) one secured to the cover 7 and the other integral with the ring 3.
