Abstract

The invention relates to a non-rechargeable package comprising a valve casing (4) with a main valve (11) and an auxiliary valve (19) cooperating with a seat (23) and initially primed in the open position by a locking disk (49) which is unlocked, at the end of a first filling, by an extension (39) of the main valve (11) rendered active by a displacement of the main valve (40) beyond its normal open position. The auxiliary valve (19) is then bearing on its seat (23) by a weak spring (46). Any underpressure during tapping off causes the auxiliary valve (19) to open, whilst any excess pressure during filling strikes the auxiliary valve (19) in the closed position.

Description

La présente invention concerne une valve pour emballage non rechargeable, du genre comprenant un boitier à valve principale montée dans un passage de communication avec ledit remballage, coopérant avec un ressort de rappel de fermeture, et présentant un moyen de poussée axiale du clapet de valve vers la position d'ouverture contre l'action du ressort. The present invention relates to a valve for non-refillable packaging, of the type comprising a main valve housing mounted in a communication passage with said repackaging, cooperating with a closing return spring, and having a means of axial thrust from the valve flap to the open position against the action of the spring.

L'utilisation de plus en plus fréquente d'emballages légers, qui ne doivent être remplis qu'une seule fois, dits emballages non rechargeables, pose des problèmes de sécurité en ce qui concerne leur réemploi éventuel, qui est généralement interdit, d'autant plus que, dans certains cas, les pressions de service peuvent en être élevées. The increasingly frequent use of light packaging, which must only be filled once, known as non-refillable packaging, poses safety problems with regard to their possible reuse, which is generally prohibited, all the more so. more than, in some cases, the operating pressures may be high.

Pour éliminer la possibilité d'un quelconque remplissage ultérieur par un utilisateur ignorant la législation, ou les dangers d'une telle opération, l'invention propose de perfectionner les valves existantes afin de permettre exclusivement le renplissage initial de ltes3ballage et d'interdire à coût sûr tout nouveau remplissage subséquent à un vidage d'utilisation. To eliminate the possibility of any subsequent filling by a user who is unaware of the legislation, or the dangers of such an operation, the invention proposes to improve the existing valves in order to allow exclusively the initial filling of the package and to prohibit at cost safe any new filling subsequent to an emptying of use.

Cet objectif de l'invention est réalisé en aménageant une valve à clapet auxiliaire montée dans ledit boitier, dont le clapet est associé à un ressort de fermeture à faible tarage et qui est, lors de sa fabrication, maintenu en position d'ouverture par un moyen de verrouillage armé initialement et dont le déverrouillage définitif ne peut être assuré que sous l'action du clapet de valve principal lors d'une action d'ouverture accentuée exercée sur le clapet principal au delà de sa course d'ouverture normale, de façon à déverrouiller ledit clapet auxiliaire et à l'amener en position de fermeture sous l'action du ressort à faible tarage, ledit moyen de verrouillage étant du type fixé à demeure à la paroi du boîtier de valve et ancré de façon amovible sur le clapet auxiliaire.Grâce à cet agencement, après avoir procédé en usine au renplissage en liquide et/ou en gaz d'un emoallage, il suffit d'exercer sur le clapet principal une action de déplacement plus accentuée pour assurer le déverrouillage du clapet de valve auxiliaire et sa venue en position de fermeture sous l'action d'un ressort à faible tarage.On comprend qu'un soutirage ultérieur est tout à fait possible, car le clapet auxiliaire vient en position d'ouverture grâce à la dépression initiale de soutirage côté aval et se déplace sous l'action de la pression interne du fluide dans ltemballage, mais reste au contraire en position fermée lors de toute tentative d'un nouveau remplissage après soutirage 3neme partiel du fluide stocké initialement, sous l'effet du ressort de clapet auxiliaire qui ramène le clapet auxiliaire en position de fermeture, position qui est d'ailleurs considérablement renforcée par la pression externe lors de cette tentative de remplissage. This objective of the invention is achieved by fitting an auxiliary valve valve mounted in said housing, the valve of which is associated with a low-setting closing spring and which is, during its manufacture, maintained in the open position by a locking means initially armed and whose final unlocking can only be ensured under the action of the main valve valve during an accentuated opening action exerted on the main valve beyond its normal opening stroke, so unlocking said auxiliary valve and bringing it into the closed position under the action of the low-setting spring, said locking means being of the type permanently fixed to the wall of the valve housing and detachably anchored on the auxiliary valve .Thanks to this arrangement, after having carried out in the factory the filling in liquid and / or gas of a packaging, it is enough to exert on the main valve a displacement action more accentuated to ensure the unlocking of the auxiliary valve flap and its coming into the closed position under the action of a spring with low setting. We understand that a subsequent withdrawal is quite possible, because the auxiliary valve comes in position d opening thanks to the initial suction depression on the downstream side and moves under the action of the internal pressure of the fluid in the packaging, but remains on the contrary in the closed position during any attempt to refill after partial withdrawal of the stored fluid initially, under the effect of the auxiliary valve spring which returns the auxiliary valve to the closed position, a position which is moreover considerably reinforced by external pressure during this attempt at filling.

Selon une forme de réalisation, le clapet auxiliaire est monté en prolongement axial du clapet principal avec des extensions axiales se faisant face, le ressort à faible tarage actif sur ledit clapet auxiliaire étant monté sur les dites extensions et prenant appui sur les dits clapets principal et auxiliaire, le moyen de verrouillage en position armée du clapet auxiliaire étant une pièce fixée à demeure au boitier et de façon amovible sur la valve auxiliaire. According to one embodiment, the auxiliary valve is mounted in axial extension of the main valve with axial extensions facing each other, the low-setting spring active on said auxiliary valve being mounted on said extensions and resting on said main valves and auxiliary, the locking means in the armed position of the auxiliary valve being a part permanently fixed to the housing and removably on the auxiliary valve.

Selon une forme préférentielle de réalisation, la pièce de verrouillage est un disque de forme annulaire dont la périphérie externe est fixée entre boîtier et culot de boîtier et présentant une pluralité de pattes radiales engagées élastiquement dans une rainure circonférentielle du corps de valve auxiliaire. According to a preferred embodiment, the locking piece is an annular disc whose external periphery is fixed between the housing and the housing base and having a plurality of radial lugs engaged elastically in a circumferential groove of the auxiliary valve body.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui suit à titre d'exemple en référence aux dessins annexés dans lesquels les figures 1 à 3 représentent l'équipement de bouteille non rechargeable, en coupe, dans trois conditions opérationnelles successives, à savoir - à la figure 1 en condition prêt pour recevoir la charge initiale avec
en encadré une vue partielle agrandie - la figure 2 en cours de charge - la figure 3 en condition soit immédiatement après déverrouillage de
fin de charge soit imnédiatement en début de soutirage soit en
tentative de nouveau roeplissage - la figure 4 est une vue en perspective de la pièce de verrouillage.The characteristics and advantages of the invention will become more apparent from the description which follows by way of example with reference to the appended drawings in which FIGS. 1 to 3 show the equipment of the non-refillable bottle, in section, under three operational conditions successive, namely - in Figure 1 in ready condition to receive the initial charge with
in box an enlarged partial view - Figure 2 during charging - Figure 3 in condition either immediately after unlocking
end of charge either immediately at the start of racking or
retrying attempt again - Figure 4 is a perspective view of the locking piece.

En se référant aux dessins annexés, une bouteille 1 à col 2 est équipée d'un boîtier de valve de tête 3 présentant un corps 4 vissé en 5 à l'intérieur du col 2 jusqu a appui serré sur un rebord supérieur 6 sur la tranche 7 du col de bouteille 2 avec interposition d'un joint d'étanchéité 8, le tout étant rendu indémontable par quelques corps de pointeau sur le col à l'endroit du pas de vis. Referring to the appended drawings, a bottle 1 with a neck 2 is equipped with a head valve housing 3 having a body 4 screwed in 5 inside the neck 2 until it is pressed tightly on an upper rim 6 on the edge 7 of the bottle neck 2 with the interposition of a seal 8, the whole being made non-removable by a few needle bodies on the neck at the place of the screw thread.

Le corps 4 du boitier de valve 3 présente un passage axial 11 avec une partie centrale 12 de logement d'un ensemble formant valve principale 13, une partie supérieure évasée 14 avec épaulement de butée 15 pour un organe de remplissage/soutirage 16, et une partie inférieure élargie 17 formant cambrage 18 pour une valve auxiliaire 19, ce chanbrage 18 étant ferme par un culot 20 vissé en 21 et présentant un passage de traversée 22 côté inférieur, précédé d'un large épaulement 23. The body 4 of the valve housing 3 has an axial passage 11 with a central part 12 for housing a main valve assembly 13, a flared upper part 14 with abutment shoulder 15 for a filling / withdrawal member 16, and a enlarged lower part 17 forming camber 18 for an auxiliary valve 19, this chamfering 18 being closed by a base 20 screwed at 21 and having a passage passage 22 on the lower side, preceded by a broad shoulder 23.

La valve principale 13 présente un corps de valve 31 vissé en 32 dais une partie supérieure du passage central 12 jusqu'à butée sur un épaulement 33. Ce corps de valve 31 présente une perforation axiale avec un épaulement de butée 35 pour un ressort de conpression 36 s'appuyant d'autre part sur une collerette amont 36 d'une tige de clapet 37 présentant une extension supérieure de manoeuvre 38 et une extension inférieure 39 à clapet proprement dit 40 incorporant un joint annulaire 41, le tout coopérant à ouverture/fermeture avec l'extrémité inférieure frontale 42 du corps de valve 31. L'extension axiale basse 39 du corps de valve 31 se présente en regard de la valve auxiliaire 19 qui, elle même, est conformée avec une extension en regard 45, un ressort de compression 46 à faible tarage étant engagé sur les extensions 39 et 45. The main valve 13 has a valve body 31 screwed in 32 into an upper part of the central passage 12 until it stops on a shoulder 33. This valve body 31 has an axial perforation with a stop shoulder 35 for a compression spring 36 resting on the other hand on an upstream flange 36 of a valve stem 37 having an upper actuating extension 38 and a lower extension 39 with valve proper 40 incorporating an annular seal 41, the whole cooperating in opening / closing with the lower front end 42 of the valve body 31. The lower axial extension 39 of the valve body 31 is opposite the auxiliary valve 19 which, itself, is shaped with an extension facing 45, a spring of compression 46 with low calibration being engaged on extensions 39 and 45.

La valve auxiliaire 19 présente en regard du passage 22 une paroi transversale formant clapet 46 avec un joint annulaire 47, le tout pouvant venir en appui étanche contre l'épaulement 23 circonscrivant le passage 22. The auxiliary valve 19 has, opposite the passage 22, a transverse wall forming a valve 46 with an annular seal 47, the whole being able to come into sealing abutment against the shoulder 23 circumscribing the passage 22.

Le corps de valve présente une rainure circonférentielle 48 de maintien provisoire de la valve auxiliaire 19 en position armée inopérative écartée du siège 23 grâce à un disque annulaire flexible 49 avec deux pattes radiales 49e et 49b engagées intérieurement dans ladite rainure 48 et dont la périphérie extérieure est coincée de façon étanche entre un épaulement 50 du culot 20 et un bord frontal 51 du corps de boitier 4. The valve body has a circumferential groove 48 for temporarily holding the auxiliary valve 19 in the inoperative armed position away from the seat 23 by means of a flexible annular disc 49 with two radial lugs 49e and 49b engaged internally in said groove 48 and whose outer periphery is tightly wedged between a shoulder 50 of the base 20 and a front edge 51 of the housing body 4.

L'organe de remplissage soutirage est de type quelconque, et présente un corps 61 adapté à être vissé en 62 dans l'évidement 14 avec une protubérance axiale inférieure 63 qui est alignée avec la tige de clapet principal 37. Ce corps 61 présente un passage axial 64 débouchant extérieurement par des conduits radiaux 65 et une tête (non représentée) incorporant le conduit 64, qui débouche dans un corps de robinet ou autre moyen de vanne contrôlée manuellement ou automatiquement.  The filling filling member is of any type, and has a body 61 adapted to be screwed at 62 into the recess 14 with a lower axial protuberance 63 which is aligned with the main valve stem 37. This body 61 has a passage axial 64 opening outwardly through radial conduits 65 and a head (not shown) incorporating the conduit 64, which opens into a valve body or other valve means controlled manually or automatically.

Avant un premier remplissage (figure 1), le corps 16 est vissé en 62 jusqu'à une position intermédiaire (figure 2) où la protubérance 63 est venue en appui sur l'extension 38 du clapet principal repoussant vers le bas la tige de clapet principal 37 et dégageant le clapet principal 40 de son siège 42. Before a first filling (FIG. 1), the body 16 is screwed at 62 to an intermediate position (FIG. 2) where the protuberance 63 comes to bear on the extension 38 of the main valve pushing down the valve stem. main 37 and releasing the main valve 40 from its seat 42.

Dans cette position intermédiaire, l'extension inférieure 39 solidaire du clapet principal 40 n'est pas encore en contact avec la protubérance 45 de la valve auxiliaire 19 qui est verrouillée en position ouverte par le disque 49. La charge peut alors avoir lieu, les deux valves principale 11 et auxiliaire 19 - étant toutes deux en position ouverte. Dès que la charge est terminée, on procède à un vissage plus poussé en 62 de l'organe de remplissage 16 (figure 3), de sorte que l'extension inférieure 39 de la valve principale 11 vient en contact avec l'extension supérieure 45 de la valve auxiliaire 19. Au delà d'une position axiale de déformation maximale, le disque de retenue 49 de la valve principale s'échappe de la rainure 48 et la valve auxiliaire 19 est définitivement libérée. In this intermediate position, the lower extension 39 integral with the main valve 40 is not yet in contact with the protuberance 45 of the auxiliary valve 19 which is locked in the open position by the disc 49. Charging can then take place, two main 11 and auxiliary 19 valves - both being in the open position. As soon as the charge is completed, a more thorough screwing is performed at 62 of the filling member 16 (FIG. 3), so that the lower extension 39 of the main valve 11 comes into contact with the upper extension 45 of the auxiliary valve 19. Beyond an axial position of maximum deformation, the retaining disc 49 of the main valve escapes from the groove 48 and the auxiliary valve 19 is definitively released.

Après quoi, la source de fluide est déconnectée et l'organe de remplissage soutirage retiré par dévissage en 62. L'emballage est prêt être stocké et/ou livré à l'utilisateur. After which, the source of fluid is disconnected and the filling filling member withdrawn by unscrewing at 62. The packaging is ready to be stored and / or delivered to the user.

Au poste d'utilisation, le cas échéant, un robinet à détendeur classique est mis en place. Toute poussée d'ouverture sur le clapet 13 provoque un soutirage gazeux et, du fait de la baisse de pression en aval du clapet auxiliaire 19, l'ouverture quasi-immediate de ce clapet auxiliaire 19, contre l'action du ressort à faible tarage 46, libérant ainsi du gaz hors de la bouteille. At the operating station, if necessary, a conventional pressure reducing valve is installed. Any opening thrust on the valve 13 causes gas to be drawn off and, due to the pressure drop downstream of the auxiliary valve 19, the almost immediate opening of this auxiliary valve 19, against the action of the spring at low setting. 46, thereby releasing gas from the bottle.

En fin de soutirage, en l'absence de surpression interne dans la bouteille, le clapet auxiliaire 19 ne peut plus se soulever, du fait de l'action de fermeture du ressort à faible tarage, et reste donc en position de fermeture sur son siège 23 sous l'action du ressort de compression 46 (figure 3). Dans cette position, toute tentative de remplissage par l'utilisateur est ainsi vouée à l'échec. blême en utilisant le robinet spécial à trois positions du poste de rewplissage, le clapet auxiliaire 19 reste définitivement en position de fermeture et toute arrivée de gaz ne peut que renforcer cette position de fermeture. L'emballage est donc à coup sûr non réutilisable.  At the end of racking, in the absence of internal overpressure in the bottle, the auxiliary valve 19 can no longer be lifted, due to the closing action of the spring at low setting, and therefore remains in the closed position on its seat. 23 under the action of the compression spring 46 (Figure 3). In this position, any attempt at filling by the user is doomed to failure. pale using the special three-position tap of the refilling station, the auxiliary valve 19 remains permanently in the closed position and any gas supply can only reinforce this closed position. The packaging is therefore certainly not reusable.
