Abstract

The preservation system is for fluids to be distributed under pressure, particularly perfume. The fluid is enclosed in a vessel under a pressure at the most equal to atmospheric, the vessel being sealed by means of a suction and pressure pump acting in one direction and allowing no air flow in the reverse direction into it. As the pump distributes the fluid, an increasing vacuum is generated inside the vesel. The pump (3) can have an immersion feed pipe (10) with its mouth at the bottom of the vessel (4). The internal volume of the pipe is at the most equal to half the working volume of the pump.

Description

Procédé de conditionnement de liquide à distribuer sous pression et conditionnent mettart en oeuvre un tel procédé.Process for conditioning liquid to be dispensed under pressure and condition the implementation of such a process.

La présente invention concerne un perfectionnement au procédé et au conditionnement décrits et revendiqués dans le brevet principal. The present invention relates to an improvement to the process and to the packaging described and claimed in the main patent.

La distribution d'un liquide par une pompe,en créant une dépression croissante à l'intérieur d'un récipient, qui fait l'objet du brevet principal, présente de nombreux avantages de simplicité de mise en eouvre et de souplesse de fonctionnement. The distribution of a liquid by a pump, by creating an increasing vacuum inside a container, which is the subject of the main patent, has many advantages of simplicity of implementation and flexibility of operation.

La pression à exercer sur le piston de la pompe, pour obtenir une bonne pulvérisation, est inférieure à celle nécessaire pour actionner une pompe classique dans un conditionnement comportant une mise à l'atmosphère à l'intérieur du récipient. The pressure to be exerted on the piston of the pump, in order to obtain good spraying, is less than that necessary to actuate a conventional pump in a package comprising an atmosphere setting inside the container.

De plus, pour la distribution des parfurns, on constate que le conditionnement avec pompe à dépression est meilleur que le conditionnement traditionnel à pression atmosphérique. In addition, for the distribution of perfumes, it can be seen that the packaging with vacuum pump is better than the traditional packaging at atmospheric pressure.

On note en effet une fragrance plus franche et plus vive qu'avec le conditionnement traditionnel. I1 semble, en effet, que la dépression provoquée dans le flacon aurait plutôt tendance à augmenter la "note" du parfum. There is indeed a more frank and livelier fragrance than with traditional packaging. It seems, in fact, that the depression caused in the bottle would tend to increase the "note" of the perfume.

Cependant,le conditionnement sous dépression présente un inconvénient fréquent qui est le désamorçage de la pompe au bout d'un temps relativement court d'inutilisation, inférieur à une journée. However, vacuum packaging has a frequent drawback, which is the defusing of the pump after a relatively short period of non-use, less than a day.

La solution classique pour éviter le désamorçage des pompes consiste à équiper l'admission de la pompe d'un clapet anti-retour. Cependant, un tel clapet présente l'inconvénient de gêner le fonctionnement d'une pompe à dépression et de nécessiter l'adjonction de pièces supplémentairesqui grèvent le prix de revient. The classic solution to avoid defusing the pumps is to equip the pump inlet with a non-return valve. However, such a valve has the drawback of hampering the operation of a vacuum pump and of requiring the addition of additional parts which increase the cost price.

On auget yéneralemerlt qu'une pompe ne fonctionne pas du premier coup àcondition que l'on obtienne la distribution du liquide au deuxième ou, à la rigueur, au troisième coup. It is generally expected that a pump does not work the first time, provided that the distribution of the liquid is obtained on the second or, if necessary, the third stroke.

L'invention a pour but de pallier l'inconvénient du désamorçage d'une pompe à dépression sans nécessiter de pièces supplémentaires et dans modifier l'assemblage du conditionnement. The invention aims to overcome the disadvantage of defusing a vacuum pump without requiring additional parts and in modifying the packaging assembly.

L'invention a pour objet un procédé de conditionnement de liquide à distribuer sous pression suivant la revendication du brevet principal, caractérisé en ce qu'on épquipe la pompe d'un tube plongeur d'alimentation débouchant au fond du récipient, le volume intérieur de ce tube étant au plus égal à la moitié du volume utile de la pompe. The subject of the invention is a process for conditioning liquid to be dispensed under pressure according to the claim of the main patent, characterized in that the pump is fitted with a supply dip tube opening at the bottom of the container, the internal volume of this tube being at most equal to half the useful volume of the pump.

L'invention a également pour objet un conditionnement dont la pompe est équipée d'un tube plongeur capillaire de diamètre intérieur inférieur à 1 mm environ
L'invention sera mieux comprise à la lecture de la description détaillée qui va suivre et a l'examen du dessin annexé qui représente, à titre d'exemple non limitatif un mode de réalisation de l'invention.The subject of the invention is also a package, the pump of which is equipped with a capillary dip tube with an internal diameter of less than approximately 1 mm.
The invention will be better understood on reading the detailed description which follows and on examining the appended drawing which represents, by way of nonlimiting example, an embodiment of the invention.

La figure annexée représente un conditionnement suivant le brevet principal essentiellement constitué par un récipient rigide 4 sur le col duquel est sertie une coupelle métallique 8 dont la partie centrale maintient une collerette 7 sertie du corps 5 d'une pompe 3. The appended figure represents a packaging according to the main patent essentially consisting of a rigid container 4 on the neck of which is crimped a metal cup 8 the central part of which holds a flange 7 crimped with the body 5 of a pump 3.

La tige de commande 1 du piston 2 de cette pompe communique par un canal d'évacuation 19 à une buse de pulvérisation 16 logée dans un bouton poussoir 15. The control rod 1 of the piston 2 of this pump communicates via an evacuation channel 19 to a spray nozzle 16 housed in a push button 15.

L'étanchéité est assurée entre la collerette 7 et la coupelle 8 autour d'n ouverture centrale 13, par un joint élastique 9 coincé par le rebord annulaire 12 d corps de pompe 5. Un piston auxiliaire 17 sollicité par un ressort de rappel 14 assure l'étanchéité par son extrémité en pointeau 18 à l'intérieur de la tige de commallde 1. Un logement en doigt de gant 6, à la partie inférieure du corps de pompe 5, maintient un tube capillaire 10 qui plonge dans le liquide à distribuer 11 au fond du récipient 4. Au fur et à mesure de la distribution du liquide 11, une dépression croissante est créé3 dans l'espace vide résiduel 20.The seal is ensured between the collar 7 and the cup 8 around a central opening 13, by an elastic seal 9 wedged by the annular flange 12 of the pump body 5. An auxiliary piston 17 biased by a return spring 14 ensures the sealing by its needle end 18 inside the control rod 1. A thimble housing 6, at the lower part of the pump body 5, maintains a capillary tube 10 which plunges into the liquid to be dispensed 11 at the bottom of the container 4. As the liquid 11 is distributed, an increasing depression is created3 in the residual empty space 20.

Dans un exemple pratique de réalisation avec une pompe équipée d'un tube capillaire de 0,8 mm de diamètre intérieur en polyéthylène ou polypropylène, le volume interne de la pompe est de 118 mm3, le volume utile de la pompe, c'est-d-dire le volume de la dose de liquide distribué à chaque coup est de 75 mm3, le volume intérieur desvcanaux du diffuseur et'de la buse est de 88 mm3. In a practical embodiment with a pump equipped with a capillary tube of 0.8 mm internal diameter made of polyethylene or polypropylene, the internal volume of the pump is 118 mm 3, the useful volume of the pump, ie the volume of the dose of liquid dispensed at each stroke is 75 mm 3, the interior volume of the channels of the diffuser and of the nozzle is 88 mm 3.

Avec un tube capillaire de 8 cm de long, le volume intérieur du tube est de 20 mm3. Le volume total d'amorçage est de 226 mm3 comprenant le remplissage du tube de la pompe et du diffuseur. Le volume de réamorçage comprenant seulement la pompe et le tube est de 138 mm3. With an 8 cm long capillary tube, the internal volume of the tube is 20 mm3. The total priming volume is 226 mm 3 including the filling of the pump tube and the diffuser. The priming volume including only the pump and the tube is 138 mm3.

On obtient ainsi,théoriquement, un amorçage de la pompe en deux ou trois coups et un réamorçage en un ou deux coups. En effet, la première pulvérisation obtenue ne correspond pas nécessairement au volume utile total.One thus obtains, theoretically, a priming of the pump in two or three strokes and a re-priming in one or two strokes. In fact, the first spray obtained does not necessarily correspond to the total useful volume.

De plus, par effet de capillarité à l'intérieur du tube le liquide en descend jamais à l'intérieur du tube au niveau extérieur du liquide. Avec le tube de l'exemple de 0,8mm de diamètre intérieur en polypropylène, la capillarité crée une différence de 9 à 10 mm du niveau du liquide ent-e l'extérieur et l'intérieur du cube
Cette différencie de niveau s'oppose au dosamorçage et facilite le réamorçage de la poè. In addition, by capillary action inside the tube the liquid never descends inside the tube at the outside of the liquid. With the tube of the example with an internal diameter of 0.8mm made of polypropylene, the capillarity creates a difference of 9 to 10 mm from the level of the liquid between the outside and the inside of the cube.
This level difference is opposed to back-priming and facilitates re-priming of the poet.

Avec un tube plongeur classique de 3 mm de diamètre intérieur, le désamorçage de la pompe survient très rapidement et le rcamorcage demande au moins un coup de pompe supplémentaire pour un tube plongeur de 8 cm de long. With a conventional dip tube with an internal diameter of 3 mm, pump priming occurs very quickly and re-initiation requires at least one more pump stroke for an 8 cm long dip tube.

Pour des conditionnements hauts de 16 cm par exemple, le réamorçage est toujours obtenu en un à deux coups de de pompe avec un tube suivant l'invention dont le plume intérieur ne dépasse pas alors 40 mm3, alors qu'il atteint 112 mm3 avec un tube classique, soit plus de deux coups de pompe supplémentaires. For packages 16 cm high, for example, the priming is always obtained in one to two pump strokes with a tube according to the invention, the inner feather of which does not then exceed 40 mm3, while it reaches 112 mm3 with a classic tube, i.e. more than two additional pump strokes.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et représenté, elle est susceptible de nombreues variantes accessibles à lthomme de l'art, suivant les applications envisagées et sans s'écarter pour cela du cadre de l'inver.tion.  Of course, the invention is in no way limited to the embodiment described and shown, it is capable of numerous variants accessible to those skilled in the art, depending on the applications envisaged and without departing from the scope of the invention. .tion.
