Definitions
- the present invention relates to a device for dispensing fluid products comprising a precompression pump and more particularly a means and a method adjusting the volume of the pump chamber of said dispensing device, allowing thus to vary the amount of product dispensed during actuation of said device.
- Such a dispenser is described for example in document FR-2 686 377 and is shown in Figure 1. It includes a precompression pump comprising a body of a cylindrical pump 1 in which an annular piston 3 slides, the piston 3 is controlled by a push rod 10 which slides in said piston 3 and which comprises a outer sleeve 11, fixed on an inner core 12, and an outlet channel 13 opening in the pump body 1 through a lateral opening 5.
- the piston cooperates with the push rod 10 for closing or clearing said lateral opening, the push rod being connected to the piston 3 by a precompression spring 8 which pushes the piston towards a rest position where it closes said lateral opening. Pressing the push rod 10 lowers it in the pump body which urges the piston 3 downwards made of precompression spring 8. This creates an overpressure in the pump 6 until this overpressure is sufficient to counterbalance the force of the precompression spring 8 and thus release the lateral opening 5 to allow the expulsion of the product contained in the pump chamber 6.
- an upper part 2 of the pump body 1 is fixedly fixed on the neck of the container by means of a hoop or capsule 20a, capable of be crimped on the upper part 2 of the pump body, and which has an opening central unit 21 through which an upper part 10 of the pump passes.
- the object of the present invention is to provide a means and a method for adjusting the volume of the pump chamber 6 of such a product dispenser comprising a pump with precompression, said means having to be easily realizable and adaptable to said product distributor without increasing manufacturing costs.
- the present invention therefore relates to a product distribution device fluid comprising a container provided with a neck and a pump fixed on said neck by means a hoop said pump comprising a pump chamber delimited by a body of pump and a piston sliding in said pump body between a rest position and an actuating position, the volume of the pump chamber being defined by the body pump and the piston rest position, said hoop having a central opening through which an upper part of said pump passes, characterized in that said hoop has, near its central opening, at least one recess having a determined depth and penetrating into the pump body, said at least one recess being with a lower part, in contact with an element of the pump determining the rest position of the piston, this being moved inside the body of pump from a distance approximately equal to the depth of said at least one recess, of so that the depth of said depression regulates the volume of the pump chamber.
- the invention therefore makes it possible to solve the aforementioned technical problem by not modifying only one piece, the hoop, which is one of the last pieces to be assembled on the Mountain range.
- the hoop which is one of the last pieces to be assembled on the Mountain range.
- said hoop has a single depression in the body of pump, said recess being annular and defining said central opening.
- said hoop with its depression has a general external shape identical regardless of the depth of said depression. It is so possible, with a single assembly unit, to make distributors with rooms with different dosing chamber volumes.
- the invention also relates to a method for adjusting the volume of a pump chamber of a pump fixed to the neck of a container by means of a hoop, said pump comprising a pump body and a piston sliding in said pump body pump between a rest position and an actuation position, the volume of the pump chamber being defined by the pump body and the piston rest position, said hoop having a central opening through which a part passes upper part of said pump, said method being characterized by the step of forming in the hoop, near the central opening, at least one recess having a determined depth and penetrating into the pump body, said recess being, with a lower part, in contact with a element of the pump determining the rest position of the piston, the latter being moved to the interior of the pump body from a distance approximately equal to the depth of said au minus one depression, so that the depth of said at least one depression regulates the volume of the pump chamber.
- a single annular depression is formed in the hoop, said annular depression defining said central opening.
- the step of forming at least one depression in the hoop is carried out by deformation of material near said central opening.
- the step of forming at least one depression in the hoop is carried out so that the fret with at least one recess has an external shape general identical regardless of the depth of said depression.
- the pump chamber 6 is delimited by the pump body 1 and the piston 3.
- the quantity of product dispensed when the device is actuated is defined by the volume of said pump chamber 6, itself defined by the rest position of the piston 3.
- the dispenser according to the invention therefore provides for change the rest position of the piston 3 to adjust the volume of the pump chamber 6. All of the components of the dispenser according to the invention are identical to those of the dispenser of the prior art described above, and will therefore not be described in new in detail, except the hoop 20b for fixing the pump body 1 on the neck of the container.
- the hoop 20b comprises near said opening central unit 21 at least one recess 30 in said pump body 1, said recess 30 being, with a lower part 31, in contact with an element of the pump determining the rest position of the piston 3.
- said rest position is defined by the precompression spring 8 resting on one side on the piston 3 and on the other side on a shoulder 11a of the sleeve 11 of the push rod 10, said part of the sleeve relying on said hoop 20a, 20b possibly via a seal seal 17, as shown in Figure 2.
- the depression 30 moves the rest position of the piston 3 inside the pump body 1 from a distance of approximately equal to the depth of said depression. Therefore, the volume of the pump is modified in proportion to the depth of the depression 30.
- said hoop 20b comprises a single annular depression 30, said annular depression 30 defining the central opening 21.
- the method of manufacturing the hoop 20b according to the invention is therefore very easily achievable, by example by simple deformation of material at the level of the central opening 21, and does not therefore requires no complicated and expensive manufacturing machine. So advantageous, provision is made to form said lower part 31 of the recess 30 under the form of a horizontal flange having at its center said central opening 21.
- This implementation of the depression 30 makes it possible to arrange the seal 17 directly under said recess 30 and avoids having to insert a flat part additional.
- the general shape of the hoops 20a, 20b is not modified. These can therefore be mounted on the distribution device by the same assembly unit independently the presence of a depression 30.
- the main advantage of the invention is therefore to allow the manufacture of product distributors with metering chambers with different volumes, on the same assembly line, by modifying only one piece, namely the hoop, which plus is one of the last to be assembled. All other components making up the product distributor are unchanged.

Abstract
Description
La présente invention concerne un dispositif de distribution de produits fluides comportant une pompe à précompression et plus particulièrement un moyen et un procédé de réglage du volume de la chambre de pompe dudit dispositif de distribution, permettant ainsi de varier la quantité de produit distribué lors d'un actionnement dudit dispositif.The present invention relates to a device for dispensing fluid products comprising a precompression pump and more particularly a means and a method adjusting the volume of the pump chamber of said dispensing device, allowing thus to vary the amount of product dispensed during actuation of said device.
De nombreux produits, par exemple dans le domaine de la pharmacie, de la cosmétique ou de la parfumerie, doivent être distribués à des doses précises, différentes selon l'utilisateur ou le type de produit. La quantité de produit émis à chaque dose doit donc être choisie pour chaque application. Dans le cas des distributeurs de produits comportant une pompe à précompression, la quantité de produit émis à chaque dose est généralement définie par le volume de la chambre de pompe.Many products, for example in the field of pharmacy, cosmetic or perfumery, should be dispensed in specific, different doses depending on the user or the type of product. The quantity of product emitted at each dose must therefore be chosen for each application. In the case of product distributors with a precompression pump, the quantity of product emitted at each dose is generally defined by the volume of the pump chamber.
Un tel distributeur est décrit par exemple dans le document FR-2 686 377 et est
représenté sur la figure 1. Il comporte une pompe à précompression comprenant un corps
de pompe cylindrique 1 dans lequel coulisse un piston annulaire 3, le piston 3 est
commandé par une tige-poussoir 10 qui coulisse dans ledit piston 3 et qui comporte un
manchon extérieur 11, fixé sur un noyau intérieur 12, et un canal de sortie 13 débouchant
dans le corps de pompe 1 par une ouverture latérale 5. Le piston coopère avec la tige-poussoir
10 pour obturer ou dégager ladite ouverture latérale, la tige-poussoir étant
connectée au piston 3 par un ressort de précompression 8 qui repousse le piston vers une
position de repos où il obture ladite ouverture latérale. Une pression sur la tige-poussoir
10 fait descendre celle-ci dans le corps de pompe ce qui sollicite le piston 3 vers le bas du
fait du ressort de précompression 8. Il se crée donc une surpression dans la chambre de
pompe 6 jusqu'à ce que cette surpression soit suffisante pour contre-balancer la force du
ressort de précompression 8 et ainsi dégager l'ouverture latérale 5 pour permettre
l'expulsion du produit contenu dans la chambre de pompe 6.Such a dispenser is described for example in document FR-2 686 377 and is
shown in Figure 1. It includes a precompression pump comprising a body
of a
Comme représenté sur la figure 1, une partie supérieure 2 du corps de pompe 1 est
assujettie fixement sur le col du récipient au moyen d'une frette ou capsule 20a, pouvant
être sertie sur la partie supérieure 2 du corps de pompe, et qui comporte une ouverture
centrale 21 à travers laquelle passe une partie supérieure 10 de la pompe.As shown in FIG. 1, an
La présente invention a pour but de fournir un moyen et un procédé de réglage du
volume de la chambre de pompe 6 d'un tel distributeur de produit comportant une pompe
à précompression, ledit moyen devant être facilement réalisable et adaptable audit
distributeur de produit sans en augmenter les coûts de fabrication.The object of the present invention is to provide a means and a method for adjusting the
volume of the
La présente invention a donc pour objet un dispositif de distribution de produit fluide comportant un récipient muni d'un col et une pompe fixée sur ledit col au moyen d'une frette ladite pompe comportant une chambre de pompe délimitée par un corps de pompe et un piston coulissant dans ledit corps de pompe entre une position de repos et une position d'actionnement, le volume de la chambre de pompe étant défini par le corps de pompe et la position de repos du piston, ladite frette comportant une ouverture centrale à travers laquelle passe une partie supérieure de ladite pompe, caractérisé en ce que ladite frette comporte, à proximité de son ouverture centrale, au moins un enfoncement ayant une profondeur déterminée et pénétrant dans le corps de pompe, ledit au moins un enfoncement étant avec une partie inférieure, en contact avec un élément de la pompe déterminant la position de repos du piston, celle-ci étant déplacée à l'intérieur du corps de pompe d'une distance environ égale à la profondeur dudit au moins un enfoncement, de sorte que la profondeur dudit enfoncement règle le volume de la chambre de pompe.The present invention therefore relates to a product distribution device fluid comprising a container provided with a neck and a pump fixed on said neck by means a hoop said pump comprising a pump chamber delimited by a body of pump and a piston sliding in said pump body between a rest position and an actuating position, the volume of the pump chamber being defined by the body pump and the piston rest position, said hoop having a central opening through which an upper part of said pump passes, characterized in that said hoop has, near its central opening, at least one recess having a determined depth and penetrating into the pump body, said at least one recess being with a lower part, in contact with an element of the pump determining the rest position of the piston, this being moved inside the body of pump from a distance approximately equal to the depth of said at least one recess, of so that the depth of said depression regulates the volume of the pump chamber.
L'invention permet donc de résoudre le problème technique précité en ne modifiant qu'une seule pièce, la frette, qui est une des dernières pièces à être assemblées sur la chaíne de montage. Ainsi, il n'est pas nécessaire pour régler le volume de la chambre de pompe de modifier une ou plusieurs pièces constitutives de la pompe elle-même, de rajouter une pièce supplémentaire, ou de modifier la chaíne de montage, ce qui entraínerait une hausse considérable du coût de fabrication.The invention therefore makes it possible to solve the aforementioned technical problem by not modifying only one piece, the hoop, which is one of the last pieces to be assembled on the Mountain range. Thus, there is no need to adjust the volume of the pump to modify one or more component parts of the pump itself, to add an additional part, or modify the assembly line, which would cause a considerable increase in the manufacturing cost.
Avantageusement, ladite frette comporte un seul enfoncement dans le corps de pompe, ledit enfoncement étant annulaire et définissant ladite ouverture centrale.Advantageously, said hoop has a single depression in the body of pump, said recess being annular and defining said central opening.
De préférence, ladite frette avec son enfoncement a une forme extérieure générale identique quelle que soit la profondeur dudit enfoncement. Il est ainsi possible, avec une seule unité d'assemblage, de réaliser des distributeurs avec des chambres ayant des volumes de chambre de dosage différents.Preferably, said hoop with its depression has a general external shape identical regardless of the depth of said depression. It is so possible, with a single assembly unit, to make distributors with rooms with different dosing chamber volumes.
L'invention a également pour objet un procédé pour régler le volume d'une chambre de pompe d'une pompe fixée sur le col d'un récipient au moyen d'une frette, ladite pompe comportant un corps de pompe et un piston coulissant dans ledit corps de pompe entre une position de repos et une position d'actionnement, le volume de la chambre de pompe étant défini par le corps de pompe et la position de repos du piston, ladite frette comportant une ouverture centrale à travers laquelle passe une partie supérieure de ladite pompe, ledit procédé étant caractérisé par l'étape de former dans la frette, à proximité de l'ouverture centrale, au moins un enfoncement ayant une profondeur déterminée et pénétrant dans le corps de pompe, ledit enfoncement étant, avec une partie inférieure, en contact avec un élément de la pompe déterminant la position de repos du piston, celle-ci étant déplacée à l'intérieur du corps de pompe d'une distance environ égale à la profondeur dudit au moins un enfoncement, de sorte que la profondeur dudit au moins un enfoncement règle le volume de la chambre de pompe.The invention also relates to a method for adjusting the volume of a pump chamber of a pump fixed to the neck of a container by means of a hoop, said pump comprising a pump body and a piston sliding in said pump body pump between a rest position and an actuation position, the volume of the pump chamber being defined by the pump body and the piston rest position, said hoop having a central opening through which a part passes upper part of said pump, said method being characterized by the step of forming in the hoop, near the central opening, at least one recess having a determined depth and penetrating into the pump body, said recess being, with a lower part, in contact with a element of the pump determining the rest position of the piston, the latter being moved to the interior of the pump body from a distance approximately equal to the depth of said au minus one depression, so that the depth of said at least one depression regulates the volume of the pump chamber.
Avantageusement, un seul enfoncement annulaire est formé dans la frette, ledit enfoncement annulaire définissant ladite ouverture centrale.Advantageously, a single annular depression is formed in the hoop, said annular depression defining said central opening.
De préférence, l'étape de former au moins un enfoncement dans la frette est réalisée par déformation de matière à proximité de ladite ouverture centrale.Preferably, the step of forming at least one depression in the hoop is carried out by deformation of material near said central opening.
De préférence, l'étape de former au moins un enfoncement dans la frette est réalisé de telle sorte, que la frette avec son au moins un enfoncement a une forme extérieure générale identique quelle que soit la profondeur dudit enfoncement.Preferably, the step of forming at least one depression in the hoop is carried out so that the fret with at least one recess has an external shape general identical regardless of the depth of said depression.
D'autres caractéristiques et avantages de la présente invention apparaítront au cours de la description suivante d'un mode de réalisation de l'invention, donnée à titre d'exemple non limitatif en regard des dessins joints.Other characteristics and advantages of the present invention will become apparent during of the following description of an embodiment of the invention, given as non-limiting example with regard to the accompanying drawings.
Sur les dessins :
- la figure 1 est une vue en coupe longitudinale d'un dispositif de distribution de produit comportant une pompe à précompression, selon l'art antérieur et,
- la figure 2 est une vue en coupe longitudinale d'un dispositif de distribution de produit selon un mode de réalisation de la présente invention incorporant le moyen de réglage du volume de la chambre de pompe.
- FIG. 1 is a view in longitudinal section of a product dispensing device comprising a precompression pump, according to the prior art and,
- Figure 2 is a longitudinal sectional view of a product dispensing device according to an embodiment of the present invention incorporating the volume control means of the pump chamber.
Comme décrit précédemment pour le distributeur de produits de l'art antérieur, en
regard de la figure 1, la chambre de pompe 6 est délimitée par le corps de pompe 1 et le
piston 3. La quantité de produit distribué lors de l'actionnement du dispositif est définie
par le volume de ladite chambre de pompe 6, lui-même défini par la position de repos du
piston 3.As described above for the distributor of products of the prior art, in
look at Figure 1, the
Le distributeur selon l'invention, représenté sur la figure 2, prévoit donc de
modifier la position de repos du piston 3 pour régler le volume de la chambre de pompe
6. Tous les éléments constitutifs du distributeur selon l'invention sont identiques à ceux
du distributeur de l'art antérieur décrit précédemment, et ne seront donc pas décrit à
nouveau en détail, sauf la frette 20b permettant de fixer le corps de pompe 1 sur le col du
récipient.The dispenser according to the invention, shown in Figure 2, therefore provides for
change the rest position of the
Ainsi, selon l'invention, la frette 20b comporte à proximité de ladite ouverture
centrale 21 au moins un enfoncement 30 dans ledit corps de pompe 1, ledit enfoncement
30 étant, avec une partie inférieure 31, en contact avec un élément de la pompe
déterminant la position de repos du piston 3. En effet, ladite position de repos est définie
par le ressort de précompression 8 s'appuyant d'un côté sur le piston 3 et de l'autre côté
sur un épaulement 11a du manchon 11 de la tige-poussoir 10, ladite partie du manchon
s'appuyant elle sur ladite frette 20a, 20b éventuellement par l'intermédiaire d'un joint
d'étanchéité 17, comme représenté sur la figure 2. Ainsi, l'enfoncement 30 déplace la
position de repos du piston 3 à l'intérieur du corps de pompe 1 d'une distance environ
égale à la profondeur dudit enfoncement. Par conséquent, le volume de la chambre de
pompe est modifié proportionnellement à la profondeur de l'enfoncement 30.Thus, according to the invention, the
Avantageusement, ladite frette 20b comporte un seul enfoncement 30 annulaire,
ledit enfoncement annulaire 30 définissant l'ouverture centrale 21. Le procédé de
fabrication de la frette 20b selon l'invention est donc très facilement réalisable, par
exemple par simple déformation de matière au niveau de l'ouverture centrale 21, et ne
nécessite donc pas de machine de fabrication compliquée et coûteuse. De manière
avantageuse, on prévoit de former ladite partie inférieure 31 de l'enfoncement 30 sous la
forme d'une bride horizontale comportant en son centre ladite ouverture centrale 21. Cette
mise en oeuvre de l'enfoncement 30 permet de disposer le joint d'étanchéité 17
directement sous ledit enfoncement 30 et évite d'avoir à intercaler une pièce plate
supplémentaire.Advantageously, said
De préférence, hormis ledit enfoncement 30 à proximité de l'ouverture centrale 21,
la forme générale des frettes 20a, 20b n'est pas modifiée. Celles-ci peuvent donc être
montées sur le dispositif de distribution par la même unité d'assemblage indépendamment
de la présence d'un enfoncement 30.Preferably, apart from said
L'avantage principal de l'invention est donc de permettre la fabrication de distributeurs de produits avec des chambres de dosage ayant des volumes différents, sur une même chaíne de montage, en ne modifiant qu'une seule pièce, à savoir la frette, qui plus est, est une des dernières à être assemblée. Tous les autres composants formant le distributeur de produit sont inchangés.The main advantage of the invention is therefore to allow the manufacture of product distributors with metering chambers with different volumes, on the same assembly line, by modifying only one piece, namely the hoop, which plus is one of the last to be assembled. All other components making up the product distributor are unchanged.
On obtient ainsi un faible coût de production et une grande flexibilité, les enfoncements pouvant être de profondeur variable, définissant par conséquent plusieurs volumes de chambre de pompe différents.This produces a low production cost and great flexibility, indentations which may be of variable depth, therefore defining several different pump chamber volumes.
