Definitions
- the present invention relates to gas cylinders and, more specifically, to liquefied petroleum gas cylinders, according to the preamble of claim 1.
- a bottle of liquefied petroleum gas has a body in one pressure-resistant material, in particular metal or material composite.
- a valve which, when it is closed, prevents gas from leaving the body.
- the action on the tap of the regulator causes a piston to move, allowing gas to flow out of the body.
- the invention provides a remedy with a bottle according to claim 1.
- Other improvements are defined in claims 2 to 6.
- the capsule in particular in plastic material, is not suitable for withstand the very high pressures prevailing, for example in a bottle liquefied petroleum gas, but may contain a gas leak occurring on the valve, as long as the leakage gas pressure does not exceed not a certain value, notably 14 bar, lower than the gas pressure prevailing in the body and however it can be easily removed from the valve by the user by moving the part which does not delimit the chamber.
- the valve includes a tubular metal chimney and the capsule includes an upper wall from which comes a tubular part open towards the bottom, the external lateral face of the tubular part coming into contact with interposition of a seal with the inner side face of the fireplace.
- the pressure it applies to the tubular part allows, by through the seal, to ensure a good seal between the inner side face of the chimney and the outer side face of the tubular part, so that gas cannot escape from the chamber.
- the chimney has an outer wall provided a shoulder and the capsule includes a skirt, a projection on the face inside of the skirt snapping under the shoulder.
- the projection may for example be a rib.
- This rib which can also be replaced by protrusions, preferably distributed evenly around the inside of the skirt, comes behind an outer rim of the valve and thus ensures that even if gas leaks and tends to repel the capsule, it is retained. Leaking gas comes to the inside of the tubular part, since the latter is open downwards and pushes the lateral surface of the tubular part towards the adjacent wall of the valve, which ensures tightness.
- the skirt flares down, which allows more easily snap on the protrusion.
- the skirt is extended downward, on the one hand, over part of the lower edge of the skirt by a tongue which results therefrom, and, on the other hand, on a second part of the lower edge of the skirt, larger than the first part, by a band connected to the lower edge of the skirt by a first line of lesser resistance to tearing.
- This band serves as a tamper-evident band. Onne can disengage the capsule only after having torn off this strip.
- the tongue connects the skirt to a ring. Even when the strip is removed, the cap remains held on the valve in a position where it tends to come back automatically due to the elasticity of the tongue, the entire capsule is preferably made of flexible plastic. The capsule still protects the valve from dust, snow, water, heat, sun, sand and other deposits of solid matter, but also valve leaks even after the tamper-evident strip has been removed.
- the lower edge of the band is connected to the ring by a second line of least resistance to tearing. This second line of least tear resistance constitutes an additional fixation of the strip and prevents it from coming off when inadvertently or by accident, the first line of least resistance to tearing is torn.
- the plastic capsule is formed of a cap, which comprises an extended circular upper wall 1 down by a skirt 2 which flares down.
- a rib 4 going all around the skirt 2 is provided on the inner face thereof.
- the skirt 2 is extended downward, on the one hand, over part of the edge lower of the skirt by a tongue 5 which results therefrom, and, on the other hand, on a second part of the lower edge of the skirt, which is larger than the first part, by a band 6 connected to the lower edge of the skirt 2 by a first line 7 of lower tear resistance, formed under the form of a series of equidistant studs.
- the tongue 5 connects the skirt 2 to a ring 8 of larger diameter than that of the lower edge of the skirt.
- the lower edge of the strip 6 is connected to the ring 8 by a second line 9 of least resistance to tearing.
- Figure 3 is a sectional view from the top of a next bottle the invention.
- This bottle has a body 10 surmounted by a neck 11 in which is screwed a valve, generally designated by 12.
- This valve includes a valve body forming an upper tubular chimney 13 the outer face of which has a shoulder 14 intended to cooperate with the projection 4.
- a ring 15 In the inner face of the body 10 is held by a ring 15 to stop a ball 16 forming a flow limiter.
- the ring carries a press spring 17 inside which is threaded a crew 18 with piston 19 pushed back upwards by a spring 20, one end of which rests on the face top of the spring press 17 and the other end of which rests on a rim 21 of the crew.
- a seal seal 22 which comes into contact with a seat 23 from the body 13 of valve.
- a seal 24 the inside diameter of which substantially corresponds to the outside diameter of the tubular part 3, in so that when it is threaded into the chimney 13, it applies there tightly through this seal 24 and defines a chamber C waterproof. If the valve leaks, gas comes into chamber C, but there is kept locked up without being able to get out of it and without any more than the force due at the pressure applied to the capsule is sufficient to lift it from the valve 12 and to set it aside due to the cooperation of the projection 4 and the shoulder 14.
- the capsule snaps on the rib 4 on the shoulder 14 of the valve 12 of the gas cylinder. In this position, it seals, even if valve 12 is leaking.
- the user detaches the tamper-evident band 6, then disengages the rib 2.
- the opening of the valve 12 can then be released, by tilting the cover relative to the tongue 5 serving as a hinge.

Abstract
Description
La présente invention se rapporte aux bouteilles de gaz et, plus
précisément, aux bouteilles de gaz de pétrole liquéfié, selon le préambule de la revendication 1.The present invention relates to gas cylinders and, more
specifically, to liquefied petroleum gas cylinders, according to the preamble of
Une bouteille de gaz de pétrole liquéfié comporte un corps en un matériau résistant à la pression, notamment en métal ou en matériau composite. Dans le goulot du corps est montée une valve qui, lorsqu'elle est fermée, empêche que du gaz ne sorte du corps. L'action sur le robinet du détendeur fait se déplacer un piston, ce qui permet que du gaz sorte du corps.A bottle of liquefied petroleum gas has a body in one pressure-resistant material, in particular metal or material composite. In the neck of the body is mounted a valve which, when it is closed, prevents gas from leaving the body. The action on the tap of the regulator causes a piston to move, allowing gas to flow out of the body.
Un danger est que la valve fuie et que du gaz sorte intempestivement du corps et se répande dans la pièce où se trouve la bouteille de gaz. There is a danger that the valve should leak and that gas could come out unexpectedly of the body and spills into the room where the gas bottle is located.
On y remédie au EP-A-194923 dans le mode de réalisation de la figure 3 par une valve montée sur le goulot de la bouteille et empêchant, lorsqu'elle est fermée, du gaz de sortir et par une capsule ayant une partie cylindrique se terminant en forme de zone sphérique délimitant avec la valve une chambre de manière à rendre la chambre étanche à du gaz sous pression. La capsule a une jupe qui ne participe pas à la délimitation de la chambre. Cette jupe est emmanchée à force sur un filetage du goulot d'une manière précise pour que l'arrachement d'un anneau de préhension provoque la destruction de la capsule. Cette capsule est dite capsule témoin et d'obturation, car outre la fonction d'obturation secondaire elle permet de constater que la bouteille n'a pas été utilisée auparavant pour en soutirer du gaz. Mais elle a deux inconvénients : elle se pose avec difficulté et nécessite un filetage sur le goulot; elle ne peut plus servir à assurer l'étanchéité secondaire une fois qu'elle a été détruite alors pourtant qu'une bouteille de gaz de pétrole liquéfié est destinée à être ouverte et refermée plusieurs fois avant d'être échangée ou rechargée.This is remedied in EP-A-194923 in the embodiment of the FIG. 3 by a valve mounted on the neck of the bottle and preventing, when closed, gas comes out and through a capsule having a part cylindrical ending in the form of a spherical zone delimiting with the valve a chamber so as to make the chamber gas tight under pressure. The capsule has a skirt which does not participate in the delimitation of the bedroom. This skirt is press fitted onto a thread on the neck of a precisely so that the tearing of a grip ring causes destruction of the capsule. This capsule is called a control capsule and shutter, because in addition to the secondary shutter function it allows find that the bottle has not been used before to extract gas. But it has two disadvantages: it arises with difficulty and requires a thread on the neck; it can no longer be used to seal secondary once it was destroyed while a bottle of liquefied petroleum gas is intended to be opened and closed several times before being exchanged or recharged.
L'invention y porte remède par une bouteille suivant la revendication
1. D'autres perfectionnements sont définis dans les revendications 2 à 6. The invention provides a remedy with a bottle according to
Certes la capsule, notamment en matière plastique, n'est pas apte à résister aux très fortes pressions qui règnent, par exemple dans une bouteille de gaz de pétrole liquéfié, mais elle est à même de contenir une fuite de gaz se produisant sur la valve, tant que la pression du gaz de fuite ne dépasse pas une certaine valeur, notamment 14 bar, inférieure à la pression du gaz régnant dans le corps et cependant elle peut être retirée facilement de la valve par l'utilisateur en déplaçant la partie qui ne délimite pas la chambre.Admittedly the capsule, in particular in plastic material, is not suitable for withstand the very high pressures prevailing, for example in a bottle liquefied petroleum gas, but may contain a gas leak occurring on the valve, as long as the leakage gas pressure does not exceed not a certain value, notably 14 bar, lower than the gas pressure prevailing in the body and however it can be easily removed from the valve by the user by moving the part which does not delimit the chamber.
Suivant un mode de réalisation qui assure une très bonne étanchéité, la valve comprend une cheminée métallique tubulaire et la capsule comprend une paroi supérieure de laquelle est issue une partie tubulaire ouverte vers le bas, la face latérale extérieure de la partie tubulaire venant en contact avec interposition d'un joint d'étanchéité avec la face latérale intérieure de la cheminée. Lorsque, en raison d'une fuite de la valve, du gaz pénètre dans la chambre, la pression qu'il applique à la partie tubulaire permet, par l'intermédiaire du joint d'étanchéité, d'assurer une bonne étanchéité entre la face latérale intérieure de la cheminée et la face latérale extérieure de la partie tubulaire, en sorte que du gaz ne peut pas sortir de la chambre.According to an embodiment which ensures a very good seal, the valve includes a tubular metal chimney and the capsule includes an upper wall from which comes a tubular part open towards the bottom, the external lateral face of the tubular part coming into contact with interposition of a seal with the inner side face of the fireplace. When, due to a valve leak, gas enters the chamber, the pressure it applies to the tubular part allows, by through the seal, to ensure a good seal between the inner side face of the chimney and the outer side face of the tubular part, so that gas cannot escape from the chamber.
Selon l'invention la cheminée a une paroi extérieure munie d'un épaulement et la capsule comprend une jupe, une saillie sur la face intérieure de la jupe s'encliquetant sous l'épaulement. Cela contribue également à obtenir une bonne étanchéité de la chambre et empêche que la capsule ne se soulève du corps sous l'effet de la pression du gaz qui a pénétré dans la chambre. La saillie peut être par exemple une nervure. Cette nervure, qui peut être remplacée également par des saillies, de préférence réparties régulièrement sur le pourtour de la face intérieure de la jupe, vient derrière un rebord extérieur de la valve et assure ainsi que, même si du gaz fuit et tend à repousser la capsule, celle-ci est retenue. Le gaz qui fuit vient à l'intérieur de la partie tubulaire, puisque celle-ci est ouverte vers le bas et repousse la surface latérale de la partie tubulaire vers la paroi adjacente de la valve, ce qui assure l'étanchéité.According to the invention the chimney has an outer wall provided a shoulder and the capsule includes a skirt, a projection on the face inside of the skirt snapping under the shoulder. This contributes also to obtain a good seal of the chamber and prevents that the capsule is lifted from the body by the pressure of the gas which entered the room. The projection may for example be a rib. This rib, which can also be replaced by protrusions, preferably distributed evenly around the inside of the skirt, comes behind an outer rim of the valve and thus ensures that even if gas leaks and tends to repel the capsule, it is retained. Leaking gas comes to the inside of the tubular part, since the latter is open downwards and pushes the lateral surface of the tubular part towards the adjacent wall of the valve, which ensures tightness.
De préférence, la jupe s'évase vers le bas, ce qui permet d'en encliqueter plus facilement la saillie.Preferably, the skirt flares down, which allows more easily snap on the protrusion.
Pour désencliqueter la saillie, il suffit de donner à la capsule un mouvement ayant une composante radiale, en sorte que la capsule bascule et se désencliquette. La force à appliquer pour le désencliquetage est petite et est à la portée de tout utilisateur habituel.To disengage the projection, simply give the capsule a movement with a radial component, so that the capsule rocks and disengages. The force to be applied for the release is small and is within the reach of any regular user.
Selon l'invention la jupe est prolongée vers le bas, d'une part, sur une partie du bord inférieur de la jupe par une languette qui en est issue, et, d'autre part, sur une seconde partie du bord inférieur de la jupe, plus grande que la première partie, par une bande reliée au bord inférieur de la jupe par une première ligne de moindre résistance à la déchirure. Cette bande sert de bande d'inviolabilité. On ne peut désencliqueter la capsule qu'après avoir arraché cette bande. According to the invention the skirt is extended downward, on the one hand, over part of the lower edge of the skirt by a tongue which results therefrom, and, on the other hand, on a second part of the lower edge of the skirt, larger than the first part, by a band connected to the lower edge of the skirt by a first line of lesser resistance to tearing. This band serves as a tamper-evident band. Onne can disengage the capsule only after having torn off this strip.
La languette relie la jupe à un anneau. Même lorsque la bande est retirée, la coiffe reste maintenue sur la valve en une position où elle tend à revenir automatiquement en raison de l'élasticité de la languette, l'ensemble de la capsule étant de préférence en matière plastique souple. La capsule protège encore la valve des poussières, de la neige, de l'eau, de la chaleur, du soleil, du sable et autre dépôt de matière solide, mais aussi des fuites de la valve, même après que la bande d'inviolabilité a été retirée. De préférence, le bord inférieur de la bande est relié à l'anneau par une seconde ligne de moindre résistance à la déchirure. Cette seconde ligne de moindre résistance à la déchirure constitue une fixation supplémentaire de la bande et empêche que celle-ci ne se détache lorsque, par inadvertance ou par accident, la première ligne de moindre résistance à la déchirure est déchirée.The tongue connects the skirt to a ring. Even when the strip is removed, the cap remains held on the valve in a position where it tends to come back automatically due to the elasticity of the tongue, the entire capsule is preferably made of flexible plastic. The capsule still protects the valve from dust, snow, water, heat, sun, sand and other deposits of solid matter, but also valve leaks even after the tamper-evident strip has been removed. Of preferably the lower edge of the band is connected to the ring by a second line of least resistance to tearing. This second line of least tear resistance constitutes an additional fixation of the strip and prevents it from coming off when inadvertently or by accident, the first line of least resistance to tearing is torn.
Au dessin annexé, donné uniquement à titre d'exemple:
Comme représenté aux figures, la capsule en matière plastique est
formée d'une coiffe, qui comprend une paroi 1 supérieure circulaire prolongée
vers le bas par une jupe 2 qui s'évase vers le bas. Une partie 3 tubulaire, de
même axe XX' que la coiffe, est issue de la face inférieure de la paroi 3
supérieure et s'ouvre vers le bas. Une nervure 4 faisant tout le tour de la jupe
2 est prévue sur la face intérieure de celle-ci.As shown in the figures, the plastic capsule is
formed of a cap, which comprises an extended circular
La jupe 2 est prolongée vers le bas, d'une part, sur une partie du bord
inférieur de la jupe par une languette 5 qui en est issue, et, d'autre part, sur
une seconde partie du bord inférieur de la jupe, qui est plus grande que la
première partie, par une bande 6 reliée au bord inférieur de la jupe 2 par une
première ligne 7 de moindre résistance à la déchirure, constituée sous la
forme d'une série de tenons équidistants.The
La languette 5 relie la jupe 2 à un anneau 8 de plus grand diamètre
que celui du bord inférieur de la jupe. Le bord inférieur de la bande 6 est relié
à l'anneau 8 par une seconde ligne 9 de moindre résistance à la déchirure. The
La figure 3 est une vue en coupe du haut d'une bouteille suivant l'invention.Figure 3 is a sectional view from the top of a next bottle the invention.
Cette bouteille comporte un corps 10 surmonté d'un goulot 11 dans
lequel est vissée une valve, désignée dans son ensemble par 12. Cette valve
comprend un corps de valve formant une cheminée 13 tubulaire supérieure
dont la face extérieure comporte un épaulement 14 destiné à coopérer avec
la saillie 4. Dans la face intérieure du corps 10 est maintenue par une bague
15 d'arrêt une bille 16 formant limiteur de débit. La bague porte un presse
ressort 17 à l'intérieur duquel est enfilé un équipage 18 à piston 19 repoussé
vers le haut par un ressort 20 dont l'une des extrémités s'appuie sur la face
supérieure du presse ressort 17 et dont l'autre extrémité s'appuie sur un
rebord 21 de l'équipage. Entre le piston 19 et le rebord 21 est prévu un joint
d'étanchéité 22 qui vient en contact avec un siège 23 issu du corps 13 de
valve. Lorsqu'un détendeur de gaz appuie sur le piston 19, l'équipage
descend vers le bas à l'encontre de la force du ressort 20 et du gaz peut
passer entre le siège 23 et le joint 22.This bottle has a
Au dessus du piston, est monté, dans un renfoncement de la face
intérieure du corps 13, un joint 24 d'étanchéité, dont le diamètre intérieur
correspond sensiblement au diamètre extérieur de la partie 3 tubulaire, en
sorte que, lorsque celle-ci est enfilée dans la cheminée 13, elle s'y applique
étroitement par l'intermédiaire de ce joint 24 d'étanchéité et délimite une
chambre C étanche. Si la valve fuit, du gaz vient dans la chambre C, mais y
est maintenu enfermé sans pouvoir en sortir et sans non plus que la force due
à la pression appliquée à la capsule suffise à la soulever de la valve 12 et à
l'en écarter en raison de la coopération de la saillie 4 et de l'épaulement 14.Above the piston, is mounted in a recess on the face
inside of the
La capsule s'encliquette par la nervure 4 sur l'épaulement 14 de la
valve 12 de la bouteille à gaz. En cette position, elle assure l'étanchéité,
même si la valve 12 fuit. Pour dégager la valve 12, l'utilisateur détache la
bande 6 d'inviolabilité, puis désencliquette la nervure 2. L'ouverture de la
valve 12 peut être alors dégagée, en faisant basculer la coiffe par rapport à la
languette 5 servant de charnière. Lorsqu'on ne veut plus prélever du gaz de la
bouteille, on laisse la coiffe 1 et 2 revenir, en raison de l'élasticité de la
languette 5, sur la valve 12, ce qui protège celle-ci de la neige, de l'eau, de la
chaleur, du soleil, du gel et de dépôt de matière solide tel que du sable et, en
la réencliquetant, assure encore l'étanchéité en cas de fuite de la valve 12.The capsule snaps on the
