Description

La présente invention concerne un dispositif de distribution d'une dose de volume déterminé d'un produit liquide ou pâteux comportant un récipient susceptible de contenir plusieurs doses de produit et un flacon susceptible de contenir une seule dose du produit, un moyen pour transférer le produit du récipient dans le flacon, et un moyen pour distribuer la dose de produit à partir du flacon.The present invention relates to a device for dispensing a dose of a determined volume of a liquid or pasty product comprising a container capable of containing several doses of product and a bottle capable of containing a single dose of the product, a means for transferring the product from the container into the bottle, and means for dispensing the dose of product from the bottle.

Il est souvent nécessaire de prélever une dose de volume bien déterminé à partir d'un récipient de stockage contenant un grand nombre de doses. C'est le cas, en particulier, dans les salons de coiffure ou d'esthétique ; il est préférable de montrer au client qu'il a bien reçu, lors des soins, la dose convenable de produit facturée, alors que le produit est stocké dans des récipients plus grands.It is often necessary to withdraw a dose of well-determined volume from a storage container containing a large number of doses. This is the case, in particular, in hairdressing or beauty salons; it is preferable to show the customer that he has indeed received, during the care, the appropriate dose of invoiced product, while the product is stored in larger containers.

On a proposé dans FR-A 2 556 091 un dispositif de ce type dans lequel on prélève dans un récipient le produit à l'aide d'un flacon du type seringue comportant un piston et une ouverture située à une extrémité du flacon et on distribue le produit par la même extrémité en repoussant le piston. Ce dispositif permet de répartir le produit mais ne permet pas de distribuer le produit par pulvérisation qui est le mode de distribution le plus généralement utilisé.A device of this type has been proposed in FR-A 2,556,091 in which the product is withdrawn from a container using a syringe-type bottle comprising a plunger and an opening situated at one end of the bottle and dispensed the product by the same end by pushing back the piston. This device makes it possible to distribute the product but does not make it possible to distribute the product by spraying which is the most generally used mode of distribution.

La présente invention concerne un dispositif qui permet de distribuer le produit par pulvérisation.The present invention relates to a device for dispensing the product by spraying.

La présente invention a pour objet un dispositif de distribution d'une dose de volume déterminé d'un produit liquide ou pâteux, comportant un récipient susceptible de contenir plusieurs doses de produit, un flacon susceptible de contenir une seule dose de produit, un moyen pour transférer le produit du récipient dans le flacon et un moyen pour distribuer le produit à partir du flacon, le flacon pouvant être fixé de façon amovible sur le récipient et pouvant coulisser longitudinalement par rapport audit récipient, caractérisé par le fait que :

  • le récipient est muni d'une première pompe comportant une tige creuse de commande, pour transférer par refoulement, le produit du récipient dans le flacon ;
  • le flacon est muni à une extrémité d'une deuxième pompe et d'une tête de distribution pour distribuer la dose de produit à partir du flacon, ledit flacon ayant à l'autre extrémité un fond adapté à coopérer avec l'extrémité de la tige de commande de la première pompe et comportant une valve obturant un canal de communication entre le flacon et le récipient et ne s'ouvrant que sous la pression du produit contenu dans le récipient lorsque la première pompe est actionnée.
The subject of the present invention is a device for dispensing a dose of a determined volume of a liquid or pasty product, comprising a container capable of containing several doses of product, a bottle capable of containing a single dose of product, a means for transferring the product from the container to the bottle and a means for dispensing the product from the bottle, the bottle being able to be fixed removably on the container and being able to slide longitudinally with respect to said container, characterized in that:
  • the container is provided with a first pump comprising a hollow control rod, for transferring by delivery, the product from the container into the bottle;
  • the bottle is provided at one end with a second pump and a dispensing head for dispensing the dose of product from the bottle, said bottle having at the other end a bottom adapted to cooperate with the end of the rod for controlling the first pump and comprising a valve closing a communication channel between the bottle and the container and opening only under the pressure of the product contained in the container when the first pump is actuated.

Ainsi donc, selon l'invention, le dispositif comporte deux pompes, une première pompe pour transférer par refoulement le produit du récipient dans le flacon, et une deuxième pompe pour effectuer la distribution ; le moyen pour transférer le produit du récipient dans le flacon est constitué par la première pompe coopérant avec la valve du fond du flacon.Thus, according to the invention, the device comprises two pumps, a first pump for transferring the product from the container into the bottle, and a second pump for dispensing; the means for transferring the product from the container to the bottle consists of the first pump cooperating with the valve at the bottom of the bottle.

La première pompe est, de préférence, une pompe dite "gros débit" qui permet de remplir le flacon en n'actionnant la pompe qu'une ou deux fois. On utilise, par exemple, de façon appropriée une pompe ayant un débit de 5 à 10 ml par coup pour alimenter un flacon de 10 ml.The first pump is preferably a so-called "high flow" pump which allows the bottle to be filled by actuating the pump only once or twice. For example, a pump having a flow rate of 5 to 10 ml per stroke is suitably used to supply a 10 ml bottle.

Avantageusement, la première pompe est fixée sur le goulot du récipient de façon amovible, la pompe et le récipient pouvant être séparés. Selon un mode de réalisation préféré, la première pompe est portée par une pièce formant bouchon comportant une jupe de fixation fermée par une paroi perpendiculaire à ladite jupe et munie d'une ouverture pour le passage du flacon lorsque la tige de commande de la première pompe est à l'intérieur du récipient ou pour le montage de la première pompe lorsque la tige de commande est extérieure au récipient, ladite pièce formant bouchon étant vissée ou claquée sur le goulot du récipient. Cette pièce est également avantageusement solidaire d'une pièce de guidage pour guider le coulissement du flacon par rapport au récipient. Les guides peuvent être disposés à l'intérieur ou à l'extérieur du récipient.Advantageously, the first pump is fixed to the neck of the container in a removable manner, the pump and the container being able to be separated. According to a preferred embodiment, the first pump is carried by a plug-forming part comprising a fixing skirt closed by a wall perpendicular to said skirt and provided with an opening for the passage of the bottle when the control rod of the first pump is inside the container or for mounting the first pump when the control rod is outside the container, said plug-forming part being screwed or slammed on the neck of the container. This piece is also advantageously secured to a guide piece for guiding the sliding of the bottle relative to the container. The guides can be arranged inside or outside the container.

Sur le goulot du flacon est disposée la deuxième pompe qui a un débit plus faible que la première pompe et qui est actionnable manuellement de l'extérieur à l'aide d'un bouton-poussoir porté par la tête de distribution. La tête de distribution est munie d'un canal de distribution s'ouvrant directement sur l'extérieur, en particulier dans le cas où le produit à distribuer est crémeux ou pâteux, ou d'un canal muni d'une buse de distribution pour pulvériser le produit à distribuer quand le produit est liquide.On the neck of the bottle is disposed the second pump which has a lower flow rate than the first pump and which is manually actuable from the outside using a push button carried by the dispensing head. The distribution head is fitted with a dispenser opening directly to the outside, in particular in the case where the product to be dispensed is creamy or pasty, or a channel provided with a dispensing nozzle for spraying the product to be dispensed when the product is liquid.

Le fond du flacon est, avantageusement, une pièce fixée, de préférence de façon amovible, sur le flacon, le flacon étant ouvert à l'extrémité opposée à celle qui porte la tête de distribution.The bottom of the bottle is advantageously a fixed part, preferably removably, on the bottle, the bottle being open at the end opposite to that which carries the dispensing head.

La valve disposée sur le fond du flacon est, de préférence, une valve comportant un corps mobile, avantageusement une bille, reposant sur un siège, le corps mobile étant maintenu en place par un moyen élastique tel qu'une lame ou un ressort hélicoïdal.The valve disposed on the bottom of the bottle is preferably a valve comprising a movable body, advantageously a ball, resting on a seat, the movable body being held in place by an elastic means such as a blade or a helical spring.

De préférence, la face extérieure du fond du flacon est pourvue d'une empreinte en creux ou cavité qui a une forme complémentaire de celle de l'extrémité de la tige de la première pompe. Dans cette empreinte s'ouvre le canal obturable par la valve qui permet de mettre en communication le récipient et le flacon.Preferably, the outer face of the bottom of the bottle is provided with a hollow imprint or cavity which has a shape complementary to that of the end of the stem of the first pump. In this imprint opens the channel closable by the valve which allows to put in communication the container and the bottle.

Le flacon est, de préférence, muni d'évents au voisinage de la tête de distribution.The bottle is preferably provided with vents in the vicinity of the dispensing head.

Le flacon est, avantageusement, muni d'un renflement, au voisinage de la tête de distribution, de façon à remplir le flacon de façon fiable jusqu'à un niveau déterminé et à empêcher que le produit sorte par les évents.The bottle is advantageously provided with a bulge, in the vicinity of the dispensing head, so as to fill the bottle reliably to a determined level and to prevent the product from escaping through the vents.

Selon un mode de réalisation du dispositif de l'invention, le flacon contient un piston libre qui est poussé par le produit lorsque l'on remplit le flacon et qui suit le produit tout au long de la distribution. De préférence, le piston libre comprime en fin de course un ressort disposé dans le flacon au voisinage de la tête de distribution.According to one embodiment of the device of the invention, the bottle contains a free piston which is pushed by the product when the bottle is filled and which follows the product throughout the dispensing. Preferably, the free piston compresses at the end of its travel a spring placed in the bottle in the vicinity of the dispensing head.

Le dispositif selon la présente invention fonctionne de la façon suivante : lorsque l'utilisateur désire remplir le flacon, il le fixe sur le récipient de façon que l'extrémité de la tige de la première pompe coopère avec le fond du flacon, puis il appuie sur le flacon de façon à enfoncer la tige de la première pompe, le flacon coulissant longitudinalement par rapport au récipient. Le produit contenu dans le récipient sort par la tige et ouvre la valve disposée dans le fond du flacon obturant le canal de communication entre le flacon et le récipient et remplit le flacon. L'utilisateur recommence éventuellement l'opération de pompage jusqu'à remplissage complet du flacon. Il sépare le flacon du récipient et, pour distribuer la dose de produit contenue dans le flacon, il actionne la seconde pompe. L'utilisateur est alors assuré de distribuer une dose déterminée de produit.The device according to the present invention operates as follows: when the user wishes to fill the bottle, he fixes it on the container so that the end of the rod of the first pump cooperates with the bottom of the bottle, then he presses on the bottle so as to push the stem of the first pump, the bottle sliding longitudinally relative to the container. The product contained in the container exits through the rod and opens the valve placed in the bottom of the bottle closing the communication channel between the bottle and the container and fills the bottle. The user may start again the pumping operation until the bottle is completely filled. He separates the bottle from the container and, to distribute the dose of product contained in the bottle, he activates the second pump. The user is then assured of dispensing a determined dose of product.

Les figures 1 à 3 représentent un dispositif qui est désigné dans son ensemble par la référence 1. Le dispositif 1 se compose d'un récipient 2 et d'un flacon 3. Le récipient 2 comporte une pompe 4 munie d'une tige creuse 5 de commande coulissant dans un corps de pompe 6. La pompe 4 est fixée par vissage sur le goulot 7 du récipient 2 à l'aide d'une pièce de fixation 8 formant bouchon qui est solidaire du corps de pompe 6 ; la pièce de fixation 8 comporte une première jupe 9 cylindrique portant sur sa face interne un filetage correspondant à celui du goulot 7 et une seconde jupe 10 également cylindrique de plus faible diamètre que celui de la jupe 9. Une partie 10a de la jupe 10 s'étend à l'intérieur du goulot 7 du récipient 2 où elle se rattache au corps de pompe 6. Dans cette partie intérieure 10a de la jupe 10 sont ménagées des fentes 11. La partie 10b de la jupe 10 s'étend à l'extérieur du goulot 7 du récipient 2 et porte à sa partie supérieure (dans la position représentée sur les figures 1 et 2) une face transversale de fermeture 12, située dans un plan perpendiculaire à l'axe de la jupe 10, fermant la pièce de fixation formant bouchon 8 de la pompe 4. Dans la face de fermeture 12 est ménagée une ouverture circulaire 13 ayant un diamètre permettant le passage du flacon 3 à travers l'ouverture 13.Figures 1 to 3 show a device which is designated as a whole by the reference 1. The device 1 consists of a container 2 and a bottle 3. The container 2 comprises a pump 4 provided with a hollow rod 5 sliding control in a pump body 6. The pump 4 is fixed by screwing on the neck 7 of the container 2 using a fixing part 8 forming a plug which is integral with the pump body 6; the fixing piece 8 comprises a first cylindrical skirt 9 carrying on its internal face a thread corresponding to that of the neck 7 and a second cylindrical skirt 10 also of smaller diameter than that of the skirt 9. A part 10 a of the skirt 10 extends inside the neck 7 of the container 2 where it is attached to the pump body 6. In this inner part 10 a of the skirt 10 are formed slots 11. The part 10 b of the skirt 10 extends outside the neck 7 of the container 2 and carries at its upper part (in the position shown in FIGS. 1 and 2) a transverse closing face 12, situated in a plane perpendicular to the axis of the skirt 10, closing the fixing part forming a plug 8 of the pump 4. In the closing face 12, a circular opening 13 is formed having a diameter allowing the passage of the bottle 3 through the opening 13.

Sur le goulot du flacon 3 est fixée une pompe 15 et une tête de distribution 14 portant une buse de pulvérisation 14b. La pompe 15 est reliée à un tube plongeur 16. Une bague de fixation 14a, cannelée pour faciliter sa préhension, est prévue pour fixer, par vissage, la tête de distribution 14 sur le goulot dont est muni le flacon 3. A la partie inférieure du flacon 3 est fixé par claquage un fond 17 qui est représenté plus en détail sur la figure 3. Ce fond 17 est constitué d'un disque 18 portant à sa périphérie une jupe 19 s'étendant, perpendiculairement au disque 18 vers le flacon 3 ; elle est munie intérieurement d'un bourrelet 20 destiné à coopérer avec un bourrelet complémentaire 21 disposé à la partie inférieure du flacon 3, la surface extérieure de la jupe 19 étant alors dans le prolongement de la paroi latérale du flacon 3. Une lèvre d'étanchéité cylindrique 22 fixée sur le disque 18 coopère avec la paroi intérieure du bourrelet 21. Au centre du disque 18 émerge une colonne 23 s'étendant axialement vers l'intérieur du flacon. La paroi extérieure de la colonne 23 est cylindrique et se raccorde avec le disque 18 par un élargissement en tronc de cône. A la base de la colonne 23 et dans le disque 18 est ménagée une empreinte ou cavité 24 de forme générale sphérique dans laquelle peut s'ajuster l'extrémité 25 de la tige 5, qui a une forme sphérique complémentaire, lorsque le flacon 3 est monté sur le récipient 2. Dans la colonne 23 est défini un canal 26 débouchant d'un côté dans l'empreinte 24 et de l'autre dans un espace intérieur élargi recevant une bille 28 et raccordé au canal 26 par une portée conique 27 servant de siège pour la bille 28. La bille 28 est maintenue par une lame élastique 29 dont les extrémités sont insérées dans la paroi intérieure de la colonne 23.On the neck of the bottle 3 is attached a pump 15 and a dispensing head 14 carrying a spray nozzle 14b. The pump 15 is connected to a dip tube 16. A fixing ring 14 a , grooved to facilitate its gripping, is provided for fixing, by screwing, the dispensing head 14 on the neck with which the bottle 3 is provided. bottom of the bottle 3 is fixed by snapping a bottom 17 which is shown in more detail in Figure 3. This bottom 17 consists of a disc 18 carrying at its periphery a skirt 19 extending, perpendicular to the disc 18 towards the bottle 3; it is internally provided with a bead 20 intended to cooperate with a complementary bead 21 disposed at the lower part of the bottle 3, the outer surface of the skirt 19 then being in the extension of the side wall of the bottle 3. A lip cylindrical seal 22 fixed on the disc 18 cooperates with the inner wall of the bead 21. At the center of the disc 18 emerges a column 23 extending axially towards the inside of the bottle. The outer wall of the column 23 is cylindrical and is connected with the disc 18 by a frustoconical enlargement. At the base of the column 23 and in the disc 18 is formed an imprint or cavity 24 of generally spherical shape in which the end 25 of the rod 5 can be adjusted, which has a complementary spherical shape, when the bottle 3 is mounted on the container 2. In the column 23 is defined a channel 26 opening on one side into the cavity 24 and on the other in an enlarged interior space receiving a ball 28 and connected to the channel 26 by a conical bearing 27 serving seat for the ball 28. The ball 28 is held by an elastic blade 29, the ends of which are inserted into the inner wall of the column 23.

Le flacon 3 est muni d'un évent, constitué par une rainure (non représentée) ménagée dans l'épaulement 30 transversal du flacon 3 à la base du goulot du flacon 3.The bottle 3 is provided with a vent, constituted by a groove (not shown) formed in the transverse shoulder 30 of the bottle 3 at the base of the neck of the bottle 3.

Le dispositif 1 fonctionne de la façon décrite ci-après. Lorsque l'utilisateur désire remplir le flacon 3 d'une dose de produit, il introduit celui-ci dans le récipient 2 par l'ouverture 13 jusqu'à ce que la cavité 24 vienne en contact avec l'extrémité de la tige 5. Lorsque le flacon 3 est en place, il enfonce le flacon 3 par coulissement dans le récipient longitudinal 2 jusqu'à ce que la bague de fixation 14a de la tête de distribution 14 vienne en butée sur la surface 12. Le flacon 3 repousse la tige 5 et la première pompe 4 est actionnée. Le liquide sous pression sort par la tige 5, passe dans le canal 26 et repousse la bille 28 qui déforme élastiquement la lame 29. Le canal 26 est ouvert et le liquide pénètre dans le flacon 3. La rainure ménagée dans l'épaulement 30 du flacon 3 permet à l'air comprimé par l'arrivée du liquide de s'échapper. L'utilisateur recommence éventuellement cette opération de pompage jusqu'à ce que le flacon 3 soit rempli. Après chaque opération de pompage, la bille 28 retombe sur son siège 27 où elle est maintenue en place par la lame 29. Le flacon 3 est alors fermé de façon étanche.The device 1 operates in the manner described below. When the user wishes to fill the bottle 3 with a dose of product, he introduces it into the container 2 through the opening 13 until the cavity 24 comes into contact with the end of the rod 5. When the bottle 3 is in place, it pushes the bottle 3 by sliding into the longitudinal container 2 until the fixing ring 14 a of the dispensing head 14 comes into abutment on the surface 12. The bottle 3 pushes the rod 5 and the first pump 4 is activated. The pressurized liquid exits through the rod 5, passes through the channel 26 and repels the ball 28 which elastically deforms the blade 29. The channel 26 is open and the liquid enters the bottle 3. The groove formed in the shoulder 30 of the bottle 3 allows the compressed air through the arrival of the liquid to escape. The user possibly repeats this pumping operation until the bottle 3 is filled. After each pumping operation, the ball 28 falls back onto its seat 27 where it is held in place by the blade 29. The bottle 3 is then sealed.

Pour distribuer la dose de liquide contenue dans le flacon 3, l'utilisateur ressort le flacon 3 du récipient 2, le transporte sur le lieu de distribution et actionne la pompe 15 en appuyant sur le bouton-poussoir de la tête de distribution 14. Le liquide est pulvérisé à travers la buse 14b.To distribute the dose of liquid contained in the bottle 3, the user takes out the bottle 3 from the container 2, transports it to the place of distribution and activates the pump 15 by pressing the push button on the dispensing head 14. The liquid is sprayed through the nozzle 14 b .

Les figures 4 à 6 représentent un autre mode de réalisation du dispositif selon l'invention, dans lequel le flacon contient un piston libre. Le dispositif est désigné dans son ensemble par la référence 101. Il comporte un récipient 102 sur lequel vient se fixer un flacon 103. Sur le goulot du récipient 102 est fixée une pompe 104 à l'aide d'une pièce de fixation 108 formant bouchon. Cette pièce 108 comporte une jupe cylindrique 110 portant un filetage interne coopérant avec un filetage externe du col du récipient 102 et un panier cylindrique 131 disposé dans le goulot du récipient 102 et ayant, au jeu nécessaire près, un diamètre égal au diamètre interne du goulot du récipient 102. Le panier 131 porte la pompe 104, la tige 105 de la pompe s'étendant dans le volume intérieur du panier 131. A la partie inférieure du panier 131, sont ménagés des évents 132 permettant d'évacuer le produit qui aurait pu pénétrer dans l'espace interne du panier 131. La pièce de fixation 108 est coiffée d'une pièce de guidage 133 qui comporte une ouverture axiale circulaire 134 d'où s'étend une jupe de guidage 135 tournée vers l'intérieur du récipient 102. Le flacon 103 est muni d'un fond 117 fixé par claquage sur le bord inférieur de la paroi latérale du flacon 103 de la même façon que le fond 17 de la variante précédente. Le fond 117 a une forme générale cylindrique se terminant par une pointe conique tournée vers l'intérieur du récipient de façon à faciliter son introduction dans le récipient 102. La colonne centrale 123 creuse définit un canal s'ouvrant du côté extérieur dans une cavité hémisphérique 124 ayant une forme complémentaire de celle de l'extrémité 125 de la tige 105 et de l'autre dans une chambre 127 communiquant avec la cavité 124 et munie d'un siège pour une bille 128. Un ressort 129 maintient la bille sur son siège. A la partie supérieure, le flacon 103 est muni d'une pompe 115 actionnée par une tête de distribution 114 munie d'une buse de pulvérisation 114b et d'une bague de fixation 114a cannelée. La pompe est reliée à un tube plongeur rigide 116. A la partie supérieure de la paroi du flacon 103 sont ménagés des évents 130. Un piston 136 ayant une forme cylindroconique est susceptible de coulisser autour du tube plongeur 116 de la pompe 115. La partie cylindrique du piston 136 est munie de lèvres extérieures 137 qui font étanchéité sur la paroi interne du flacon 103 et de lèvres 138 internes qui font étanchéité sur le tube plongeur 116 de la pompe 115. Un ressort 139 entoure le corps de la pompe 115 à la partie supérieure du flacon 103.Figures 4 to 6 show another embodiment of the device according to the invention, in which the bottle contains a free piston. The device is designated as a whole by the reference 101. It comprises a container 102 on which is fixed a bottle 103. On the neck of the container 102 is fixed a pump 104 using a fixing piece 108 forming a plug . This part 108 comprises a cylindrical skirt 110 carrying an internal thread cooperating with an external thread of the neck of the container 102 and a cylindrical basket 131 disposed in the neck of the container 102 and having, with the necessary clearance close, a diameter equal to the internal diameter of the neck of the container 102. The basket 131 carries the pump 104, the rod 105 of the pump extending in the interior volume of the basket 131. At the bottom of the basket 131, vents 132 are provided for discharging the product which could have entered the internal space of the basket 131. The fixing piece 108 is capped with a guide piece 133 which has a circular axial opening 134 from which s extends a guide skirt 135 facing inside the container 102. The bottle 103 is provided with a bottom 117 fixed by snap-fastening on the lower edge of the side wall of the bottle 103 in the same way as the bottom 17 of the variant previous. The bottom 117 has a generally cylindrical shape ending in a conical point facing the inside of the container so as to facilitate its introduction into the container 102. The central hollow column 123 defines a channel opening on the outside in a hemispherical cavity 124 having a shape complementary to that of the end 125 of the rod 105 and of the other in a chamber 127 communicating with the cavity 124 and provided with a seat for a ball 128. A spring 129 maintains the ball on its seat . At the upper part, the bottle 103 is provided with a pump 115 actuated by a dispensing head 114 provided with a spray nozzle 114 b and with a fixing ring 114 a grooved. The pump is connected to a rigid dip tube 116. Vents 130 are provided at the upper part of the wall of the bottle 103. A piston 136 having a cylindrical-conical shape is capable of sliding around the dip tube 116 of the pump 115. The part cylindrical piston 136 is provided with outer lips 137 which seal on the inner wall of the bottle 103 and 138 inner lips which seal on the dip tube 116 of the pump 115. A spring 139 surrounds the body of the pump 115 at the upper part of the bottle 103.

Le dispositif 101 fonctionne de façon analogue au dispositif 1. L'utilisateur enfonce le flacon 103 dans le récipient 102 jusqu'à ce que l'extrémité 125 de la tige 105 vienne se placer dans la cavité 124. L'utilisateur pousse alors le flacon 103 pour actionner la pompe 104 en enfonçant la tige 105 jusqu'à ce que la tête de distribution 114 vienne en butée sur la pièce de guidage 133. Le liquide sous pression contenu dans le récipient 102 vient pousser la bille 128 qui comprime le ressort 129. Le liquide pénètre dans le flacon 103 et soulève le piston 136 qui, en fin de remplissage du flacon 103 vient comprimer le ressort 139. L'air comprimé au-dessus du piston 136 s'échappe par les évents 130.The device 101 operates in a similar fashion to the device 1. The user pushes the bottle 103 into the container 102 until the end 125 of the rod 105 comes to be placed in the cavity 124. The user then pushes the bottle 103 to actuate the pump 104 by pushing the rod 105 until the dispensing head 114 abuts on the guide piece 133. The liquid under pressure contained in the container 102 pushes the ball 128 which compresses the spring 129 The liquid enters the bottle 103 and lifts the piston 136 which, at the end of filling of the bottle 103 compresses the spring 139. The compressed air above the piston 136 escapes through the vents 130.

Pour utiliser la dose du flacon 103, l'utilisateur sépare le flacon 103 du récipient 102 et le transporte sur le lieu de distribution où il actionne la pompe 115 à l'aide de la tête de distribution 114 pour pulvériser le liquide par la buse 114b. Au cours de la pulvérisation, le piston libre 136 redescend et, lorsque la dose est conditionnée,vient reprendre sa place à la partie inférieure du flacon 103.To use the dose of the bottle 103, the user separates the bottle 103 from the container 102 and transports it to the dispensing location where he actuates the pump 115 using the dispensing head 114 to spray the liquid through the nozzle 114 b . During spraying, the free piston 136 descends and, when the dose is conditioned, comes back to its place at the bottom of the bottle 103.

Le ressort 139 permet à l'air d'entrer par la prise d'air interne et non par la valve à bille dès qu'on actionne la pompe 115.The spring 139 allows air to enter through the internal air intake and not through the ball valve as soon as the pump 115 is activated.

La présence du piston libre 136 qui est en contact permanent avec le liquide permet une utilisation du flacon 103 aussi bien tête en bas que tête en haut, ce qui facilite souvent l'application, par exemple en coiffure.The presence of the free piston 136 which is in permanent contact with the liquid makes it possible to use the bottle 103 both upside down and upside down, which often facilitates application, for example in hairdressing.

La figure 7 représente partiellement un dispositif 201 qui est une variante du dispositif 101 dans laquelle le tube plongeur 216 de la pompe 215 est souple et collabore avec l'ouverture 238 du piston 236.FIG. 7 partially represents a device 201 which is a variant of the device 101 in which the dip tube 216 of the pump 215 is flexible and collaborates with the opening 238 of the piston 236.

La figure 8 représente partiellement un dispositif 301 qui est une variante du dispositif 101 dans laquelle la tige 305 de la pompe 304 est située à l'extérieur du récipient 302 et où la jupe de guidage 335 de la pièce de guidage 333 du flacon est extérieure au récipient 302 et protège la tige 305.FIG. 8 partially represents a device 301 which is a variant of the device 101 in which the rod 305 of the pump 304 is located outside the container 302 and where the guide skirt 335 of the guide piece 333 of the bottle is external to container 302 and protects the rod 305.

La figure 9 représente un autre mode de réalisation du flacon. Le flacon 403 comporte une partie renflée 403a au voisinage de son extrémité portant la tête de distribution 414. Cette partie renflée 403a permet de remplir de façon plus fiable le flacon 403 jusqu'à un niveau bien déterminé. En effet, après avoir atteint la partie inférieure de la partie renflée, le niveau du produit à distribuer monte moins vite dans le flacon et il est plus facile de s'arrêter. Par ailleurs, on évite que le niveau monte jusqu'aux évents (non représentés) ménagés à la partie supérieure du flacon.Figure 9 shows another embodiment of the bottle. The bottle 403 has a bulged part 403 a in the vicinity of its end carrying the dispensing head 414. This bulged part 403 a allows the bottle 403 to be filled more reliably up to a well-determined level. In fact, after reaching the lower part of the swollen part, the level of the product to be dispensed rises more slowly in the bottle and it is easier to stop. Furthermore, it is avoided that the level rises to the vents (not shown) formed at the top of the bottle.
