Description
DISPOSITIF DE CONDITIONNEMENT ET DISTRIBUTION D'UN PRODUIT AVEC FLACON ET EMBOUT MUNI DE JONCS ANNULAIRES. DEVICE FOR PACKAGING AND DISPENSING A PRODUCT WITH BOTTLE AND TIP PROVIDED WITH ANNULAR JUNCLES.
La présente Invention se rapporte au domaine technique de l'emballage, et plus spécialement à celui du conditionnement et de la distribution d' un produit liquide semi-fluide ou en suspension destiné à être conservé d'une manière étanche et stérile, sans l'adjonction de conservateur, et à être distribué sous forme de gouttes à l'aide d'un ensemble distributeur muni d' un embout. The present invention relates to the technical field of packaging, and more particularly to that of packaging and distribution of a semi-fluid or suspended liquid product intended to be stored in a sealed and sterile manner, without the addition of preservative, and to be dispensed in the form of drops using a dispenser assembly provided with a nozzle.
L' invention a plus particulièrement pour objet un dispositif de conditionnement et distribution d' un produit stérile, et qui comprend un récipient destiné à contenir le produit devant être distribué à l'aide d'un embout, du type sans entrée d'air, dont le récipient est muni . The invention more particularly relates to a device for packaging and dispensing a sterile product, and which comprises a container intended to contain the product to be dispensed using a nozzle, of the type without air intake, with which the container is provided.
Un tel dispositif est décrit dans les brevets US5605257 et EP1458621 dans lequel la distribution du produit est obtenue par une pression exercée par l'utilisateur sur les parois du récipient à l'aide d'un ensemble de distribution comprenant un embout . Such a device is described in patents US5605257 and EP1458621 in which the distribution of the product is obtained by a pressure exerted by the user on the walls of the container using a distribution assembly comprising a nozzle.
Cet embout comprend une partie souple en coopération avec une partie rigide de telle façon que l'extrémité élastique de ladite parte souple s'écarte de l'extrémité de ladite partie rigide lorsqu'une pression est exercée sur le récipient, permettant ainsi à une portion de produit d'être expulsée, et revient à sa position initiale sous l'effet de son élasticité sans permettre à l'air extérieur de pénétrer à l'intérieur du récipient . This tip includes a flexible part in cooperation with a rigid part so that the elastic end of said flexible part moves away from the end of said rigid part when pressure is exerted on the container, thus allowing a portion of product to be expelled, and returns to its initial position under the effect of its elasticity without allowing outside air to penetrate inside the container.
Ces brevets prévoient de ménager un emplacement pour un filtre dont le but est de rendre stérile l'air entrant dans le récipient afin de compenser la dépression créée par la distribution d' une portion de produit ; ce filtre est placé dans l'ensemble distributeur. These patents provide for a location for a filter whose purpose is to make the air entering the container sterile in order to compensate for the depression. created by the distribution of a portion of product; this filter is placed in the distributor assembly.
Ces brevets décrivent également un clapet associé au filtre et opérant de manière qu' il puisse laisser entrer l'air dans le flacon et s'opposer à toute sortie d'air ou de liquide vers l'extérieur du flacon. These patents also describe a valve associated with the filter and operating in such a way that it can allow air to enter the bottle and oppose any outflow of air or liquid to the outside of the bottle.
Un tel dispositif est également décrit dans le brevet EP1773676 qui prévoit la possibilité de distribuer le produit par une action de l'utilisateur sur les parois d'une chambre de dosage ménagée à l'intérieur de l'embout distributeur . Such a device is also described in patent EP1773676 which provides for the possibility of dispensing the product by action of the user on the walls of a metering chamber provided inside the dispensing nozzle.
La caractéristique des dispositifs de ce genre réside dans la construction de l'ensemble partie souple et partie rigide que comprend l'extrémité de l'embout distributeur, de telle manière que ledit ensemble permette la sortie du liquide lorsqu'une pression est exercée soit sur le récipient lui-même soit sur la chambre de dosage, mais s'oppose à toute entrée de l'air extérieur dans le récipient lorsque ladite pression cesse ou même lorsque le dispositif n'est plus sollicité mais reste soumis à des manipulations extérieures . The characteristic of devices of this kind resides in the construction of the flexible part and rigid part assembly which comprises the end of the dispensing nozzle, in such a way that said assembly allows the exit of the liquid when pressure is exerted on the container itself is on the metering chamber, but opposes any entry of outside air into the container when said pressure ceases or even when the device is no longer stressed but remains subject to external manipulations.
L'introduction indésirable de l'air extérieur non stérile au travers de cet embout vers l'intérieur du récipient aurait pour effet de contaminer le produit contenu à l'intérieur dudit récipient et de rendre inopérant l'ensemble du dispositif. The undesirable introduction of non-sterile outside air through this nozzle towards the inside of the container would have the effect of contaminating the product contained inside said container and rendering the entire device inoperative.
La difficulté provient du fait que l'étanchéité de l'ensemble partie souple et partie rigide est délicate et que, pour être efficace la surface de contact entre ladite partie souple élastique et ladite partie rigide doit être importante . The difficulty stems from the fact that the tightness of the flexible part and rigid part assembly is delicate and that, to be effective, the contact surface between said elastic flexible part and said rigid part must be large.
Or plus cette surface de contact est importante et meilleure est son efficacité et sa résistance à l'entrée des bactéries mais plus la pression nécessaire à exercer pour obtenir la distribution du produit est élevée . The more this contact surface is large and the better its effectiveness and resistance to the entry of bacteria, but the higher the pressure necessary to exert to obtain the distribution of the product is high.
Or cette pression est déterminante dans le bon fonctionnement du dispositif et doit rester d' une valeur acceptable afin que son utilisation soit aisée . However, this pressure is decisive in the proper functioning of the device and must remain of an acceptable value so that its use is easy.
Il est à noter que la force de serrage entre les parties souple et rigide de l'embout n'intervient pas dans la résistance de l'ensemble au passage des bactéries . It should be noted that the clamping force between the flexible and rigid parts of the end piece does not intervene in the resistance of the assembly to the passage of bacteria.
En effet les bactéries sont très mobiles et de très petite taille (quelques microns) et si elles ont la capacité à pénétrer dans le moindre interstice puis à cheminer en direction de l'intérieur du récipient vers lequel elles sont attirées, elles ne disposent par contre d' aucune force capable de vaincre mécaniquement le serrage entre les deux parties de l'embout. In fact the bacteria are very mobile and very small (a few microns) and if they have the capacity to penetrate into the smallest interstice and then to travel towards the interior of the container to which they are attracted, they do not have on the other hand of no force capable of mechanically overcoming the tightening between the two parts of the endpiece.
Le serrage entre lesdites deux parties peut par conséquent être très faible (environ de 50 à 250 mbar) et ainsi faciliter leur ouverture en ne nécessitant qu'une faible pression. The tightening between said two parts can therefore be very low (about 50 to 250 mbar) and thus facilitate their opening by requiring only a low pressure.
Seule la surface de contact entre ces deux parties intervient de manière que le cheminement des bactéries soit rendu le plus long et le plus difficile possible et que ces dernières rencontrent un obstacle s'opposant à leur progression vers l'intérieur du récipient. Only the contact surface between these two parts intervenes so that the path of the bacteria is made as long and as difficult as possible and that the latter encounter an obstacle preventing their progression towards the interior of the container.
S'il est quasiment impossible de s'opposer d'une manière absolue au cheminement des bactéries dont la taille est de quelques dixièmes de microns, notamment à cause des imperfections des parties souple et rigide de l'embout dues aux aléas de la fabrication, par contre il est possible de s'opposer à leur cheminement pendant une durée suffisamment longue pour que le dispositif soit opérant . If it is almost impossible to oppose absolutely the path of bacteria whose size is a few tenths of a micron, in particular because of the imperfections of the flexible and rigid parts of the nozzle due to the vagaries of manufacturing, on the other hand it is possible to oppose their progress during a long enough for the device to operate.
Force est de constater que les brevets précités ne donnent aucune indication sur la construction de l'ensemble partie souple et partie rigide, et a fortiori aucune indication qui permette de résoudre le problème contradictoire entre une bonne étanchéité aux bactéries et une faible pression indispensable au bon fonctionnement du dispositif. It is clear that the aforementioned patents give no indication of the construction of the flexible part and rigid part assembly, and a fortiori no indication which makes it possible to resolve the contradictory problem between a good seal against bacteria and a low pressure essential for good operation of the device.
Un premier but de l'invention est d'obtenir une bonne résistance de l'embout au cheminement des bactéries de l'extérieur vers l'intérieur du récipient. A first object of the invention is to obtain good resistance of the nozzle to the path of bacteria from the outside to the inside of the container.
Un autre but de l'invention est de permettre une utilisation aisée du dispositif en ne nécessitant qu'une force d'appui nécessaire à son fonctionnement aussi faible que possible. Another object of the invention is to allow easy use of the device by requiring only a support force necessary for its operation as low as possible.
Plus généralement, l'invention a pour but de remédier aux inconvénients des dispositifs analogues de 1 ' état de la technique et de proposer un tel dispositif qui convienne mieux aux diverses exigences de la pratique que les dispositifs connus. More generally, the object of the invention is to remedy the drawbacks of analogous devices of the prior art and to propose such a device which is better suited to the various requirements of the practice than the known devices.
A l'effet d'atteindre les buts recherchés par l'invention, celle-ci propose un dispositif de conditionnement et distribution d'un produit, généralement liquide semi-fluide ou en suspension comprenant : In order to achieve the aims sought by the invention, the latter proposes a device for packaging and distributing a product, generally a semi-fluid liquid or in suspension, comprising:
- un accessoire de distribution composé d'une partie rigide en coopération avec une partie souple, qui s'étend longitudinalement autour d'un axe longitudinal jusqu'à une extrémité libre ; - a dispensing accessory composed of a rigid part in cooperation with a flexible part, which extends longitudinally around a longitudinal axis to a free end;
- un récipient destiné à contenir le produit à conditionner et distribuer à l'aide dudit accessoire de distribution, ledit accessoire de distribution permettant au produit d'être expulsé vers l'extérieur lorsqu'une ou plusieurs parois latérales dudit récipient sont comprimées ou lorsqu'au moins une paroi actionnable dudit accessoire de distribution est actionnée mais ne permettant pas à l'air d'entrer à l'intérieur du récipient lorsque le dispositif n'est plus sollicité, le dispositif comprenant en outre un ensemble de renouvellement et de filtration de l'air entrant dans le récipient après la distribution d' une portion ou dose de produit, les dites parties souple et rigide étant aptes à s'écarter radialement l'une de l'autre par déformation d'un tronçon de contact, de forme généralement tubulaire, appartenant à la partie souple afin de permettre l'expulsion vers l'extérieur dudit produit, ledit tronçon de contact et la partie rigide étant par défaut mutuellement en contact de façon discontinue en formant plusieurs zones de contact dont des zones de contact axialement espacées entre elles . - a container intended to contain the product to be packaged and distributed using said accessory dispensing, said dispensing accessory allowing the product to be expelled to the outside when one or more side walls of said container are compressed or when at least one actuatable wall of said dispensing accessory is actuated but not allowing air to enter the interior of the container when the device is no longer used, the device further comprising a set of renewal and filtration of the air entering the container after the distribution of a portion or dose of product, said flexible and rigid parts being able to move radially apart from each other by deformation of a contact section, of generally tubular shape, belonging to the flexible part in order to allow expulsion to the outside of said product, said contact section and the rigid part being by default mutually in contact in a discontinuous manner by forming several contact zones including contact zones a xially spaced apart.
Ainsi le dispositif permet de distribuer des portions ou doses de produit par simples pressions sur les parois du récipient ou sur la partie souple de l'embout dont l'accessoire est muni, de compenser la dépression ainsi créée dans le récipient par une arrivée d'air, de préférence stérile, au travers de l'ensemble de renouvellement et filtration, de telle manière qu' il puisse être actionné facilement, sans nécessiter une force d'activation excessive, tout en s'opposant d'une manière efficace à la pénétration des bactéries à l'intérieur du récipient. Thus the device makes it possible to distribute portions or doses of product by simple pressures on the walls of the container or on the flexible part of the nozzle with which the accessory is provided, to compensate for the depression thus created in the container by an arrival of air, preferably sterile, through the renewal and filtration assembly, so that it can be actuated easily, without requiring excessive activation force, while effectively opposing penetration bacteria inside the container.
Avantageusement, la surface de contact entre la partie rigide et la partie souple que comprend l'embout de distribution est de nature discontinue et comporte des joncs annulaires en nombre suffisant pour s'opposer efficacement à la progression des bactéries de l'extérieur vers l'intérieur du récipient, tout en offrant une faible résistance à la pression nécessaire à la distribution du produit par l'ouverture entre lesdites parties rigide et souple . Advantageously, the contact surface between the rigid part and the flexible part that the end piece comprises distribution is discontinuous in nature and has sufficient annular rods to effectively oppose the progression of bacteria from the outside to the inside of the container, while offering a low resistance to the pressure necessary for the distribution of the product by the opening between said rigid and flexible parts.
Suivant une option le dispositif comprend une ou des chambres de dosage, et l'accessoire de distribution, pourvu de ladite paroi actionnable, permet au produit d'être expulsé vers l'extérieur lorsque ladite paroi actionnable est actionnée, de préférence en étant poussée radialement vers l'intérieur, de façon à comprimer la ou les chambres de dosage sans permettre à l'air d'entrer à l'intérieur du récipient lorsque le dispositif n'est plus sollicité . According to an option, the device comprises one or more metering chambers, and the dispensing accessory, provided with said actuatable wall, allows the product to be expelled towards the outside when said actuatable wall is actuated, preferably by being pushed radially. inwardly, so as to compress the metering chamber or chambers without allowing air to enter the interior of the container when the device is no longer stressed.
Selon une particularité lesdites parties souple et rigide sont mutuellement en contact de façon discontinue en formant au moins deux zones d' étanchéité par contact radial annulaire, de préférence au moins trois zones d'étanchéité par contact radial annulaire, le tronçon de contact de ladite partie souple formant un joint labyrinthique qui s'étend longitudinalement entre ladite chambre de dosage et l'extrémité libre.

Suivant une option le tronçon de contact comporte des joncs d'étanchéité de préférence annulaires, qui délimitent deux gorges circonférentielles intermédiaires . According to an option, the contact section comprises preferably annular sealing rods, which delimit two intermediate circumferential grooves.
Suivant une autre option le tronçon de contact définit au moins trois contacts circulaires d'étanchéité radiale successifs contre la partie rigide, par lesdits joncs d'étanchéité. According to another option, the contact section defines at least three circular successive radial sealing contacts against the rigid part, by said sealing rods.
Suivant une particularité les joncs d'étanchéité sont séparés par des espaces circulaires . According to a particularity the sealing rods are separated by circular spaces.
Suivant une autre particularité le dispositif comporte des joncs d'étanchéité qui sont séparés par des espaces en creux et/ou des entailles qui ne s'étendent pas sur la totalité de la circonférence de la partie souple . According to another particular feature, the device comprises sealing rods which are separated by recessed spaces and / or notches which do not extend over the entire circumference of the flexible part.
Suivant une autre particularité les joncs possèdent une hauteur maximale de 0,3 à 1 mm, mesurée parallèlement à l'axe longitudinal, lesdits joncs d'étanchéité n'ayant pas nécessairement chacun la même hauteur. According to another particular feature, the rods have a maximum height of 0.3 to 1 mm, measured parallel to the longitudinal axis, said sealing rods not necessarily each having the same height.
Optionnellement la partie souple entoure la partie rigide qui est cylindrique à proximité de ladite extrémité libre pour former une surface cylindrique de contact sur laquelle s'appuient radialement vers l'intérieur les joncs d'étanchéité inclus dans le tronçon de contact de la partie souple . Optionally, the flexible part surrounds the rigid part which is cylindrical near said free end to form a cylindrical contact surface on which the sealing rods included in the contact section of the flexible part bear radially inwards.

- la figure 6 est une vue analogue à la figure 5 représentant l'espace entre deux joncs réduit à un secteur. - Figure 6 is a view similar to Figure 5 showing the space between two rods reduced to a sector.
Tel que représenté sur la figure 1, le dispositif de conditionnement et distribution comprend un récipient 1 dans lequel est contenu le produit à distribuer 2, un espace libre 3 situé au-dessus du liquide 2, un accessoire de distribution 15 composé d'une partie rigideAs shown in Figure 1, the packaging and distribution device comprises a container 1 in which is contained the product to be dispensed 2, a free space 3 located above the liquid 2, a distribution accessory 15 composed of a rigid part
7 et d'une partie souple 8, l'extrémité de ladite partie souple 8 comportant des joncs d'étanchéité 13, 13a, 13b et 13c, des espaces libres 14, 14a et 14b, et coopérant avec l'extrémité de ladite partie rigide 7 afin de permettre au produit contenu dans ledit récipient 1 d'être expulsé de l'intérieur dudit récipient 1 lorsque celui-ci est comprimé mais ne permettant pas à l'air extérieur de pénétrer dans ledit récipient 1 lorsque celui-ci n'est plus comprimé, un orifice 11 permettant au produit 2 de s'acheminer de l'intérieur du récipient 1 vers l'embout distributeur 15, un ensemble de filtration de l'air de renouvellement comprenant un filtre stérilisant 4 associé à une valve 5 qui permet à l'air extérieur de renouvellement de pénétrer à l'intérieur du récipient après la distribution d' une goutte de produit 2 mais s'oppose à toute sortie d'air ou de produit 2 de l'intérieur vers l'extérieur du récipient 1. 7 and a flexible part 8, the end of said flexible part 8 comprising sealing rods 13, 13a, 13b and 13c, free spaces 14, 14a and 14b, and cooperating with the end of said rigid part 7 in order to allow the product contained in said container 1 to be expelled from the interior of said container 1 when the latter is compressed but not allowing outside air to penetrate into said container 1 when the latter is not more compressed, an orifice 11 allowing the product 2 to pass from the interior of the container 1 to the dispensing nozzle 15, a set of filtration of the renewal air comprising a sterilizing filter 4 associated with a valve 5 which allows outside air renewal to enter the interior of the container after dispensing a drop of product 2 but opposes any air or product 2 from the inside to the outside of the container 1 .
Le dispositif tel que représenté sur la figure 2 fonctionne de la manière suivante . The device as shown in Figure 2 operates as follows.
Un appui sur les parois du récipient 1 suivant les flèches A et A' entraîne une diminution du volume 3 de l'air situé au-dessus du produit 2 créant ainsi une pression P qui s'exerce sur la surface du produit 2. Pressing on the walls of the container 1 according to the arrows A and A ′ causes a reduction in the volume 3 of the air located above the product 2 thus creating a pressure P which is exerted on the surface of the product 2.
Soumis à cette pression P le produit 2 est entraîné vers l'embout distributeur 15 au travers de l'orifice 11 suivant la flèche B puis suivant le canal 9 vers la zone 10 située entre les parties rigide 7 et souple 8 de l'extrémité dudit embout 15. Subject to this pressure P the product 2 is driven towards the dispensing nozzle 15 through the orifice 11 along the arrow B then along the channel 9 towards the zone 10 located between the rigid 7 and flexible 8 parts of the end of said end cap 15.
Sous l'effet de la pression P, le produit 2 provoque l'écartement de l'extrémité de la partie souple Under the effect of the pressure P, the product 2 causes the separation of the end of the flexible part
8 de l'extrémité de la partie rigide 7 entraînant la distribution d'une goutte de produit 2 vers l'extérieur du dispositif au travers de la zone 10. 8 of the end of the rigid part 7 causing the distribution of a drop of product 2 towards the outside of the device through the zone 10.
Lorsque l'appui sur les parois du récipient cesse, le dispositif n'est plus sollicité et l'élasticité de l'extrémité de l'embout souple 8 entraîne son retour à sa position initiale et la fermeture de la zone 10. When the pressure on the walls of the container ceases, the device is no longer stressed and the elasticity of the end of the flexible tip 8 causes it to return to its initial position and the zone 10 to close.
Le principe de fonctionnement du dispositif tel que représenté sur la figure 3 est identique à celui de la figure 2, mais l'appui est exercé sur la partie 17 de l'embout souple 8 au niveau des chambres de dosage 16 suivant les flèches D et D' et non plus sur les parois du récipient 1. The operating principle of the device as shown in FIG. 3 is identical to that of FIG. 2, but the support is exerted on the part 17 of the flexible end piece 8 at the metering chambers 16 according to the arrows D and From and no longer on the walls of the container 1.
Un clapet 18 est disposé dans l'orifice de communication 11 afin de s'opposer au retour du produit 2 vers l'intérieur du récipient 1 lorsqu'une pression est exercée sur les chambres 16. A valve 18 is placed in the communication orifice 11 in order to oppose the return of the product 2 towards the interior of the container 1 when pressure is exerted on the chambers 16.
La figure 4 représente le détail de l'extrémité de l'embout distributeur 15 lorsque le dispositif n'est pas sollicité . Figure 4 shows the detail of the end of the dispensing nozzle 15 when the device is not stressed.
L'extrémité de la parte souple 8 qui coopère avec l'extrémité de l'embout rigide 7 est munie de plusieurs joncs d'étanchéité 13, 13a, 13b et 13c qui sont séparés par des espaces libres 14, 14a et 14b qui n'offrent pas de contact entre les parties souple 8 et rigide 7. The end of the flexible part 8 which cooperates with the end of the rigid end piece 7 is provided with several sealing rods 13, 13a, 13b and 13c which are separated by free spaces 14, 14a and 14b which do not offer no contact between the flexible 8 and rigid 7 parts.
Une pression P exercée sur le produit 2 entraîne son passage dans le canal 9 et l'ouverture du premier jonc 13. A pressure P exerted on the product 2 causes it to pass through the channel 9 and the opening of the first rod 13.
Le produit 2 pénètre alors dans le premier espace libre 14. The product 2 then enters the first free space 14.
Lorsque cet espace est entièrement rempli du produit 2 la pression P s'exerce alors sur le deuxième jonc 13a et provoque son ouverture permettant au produit 2 de pénétrer dans l'espace libre suivant 14a. When this space is completely filled with the product 2, the pressure P is then exerted on the second rod 13a and causes its opening allowing the product 2 to enter the next free space 14a.
Une action similaire est alors exercée successivement sur les joncs et espaces libres suivants. A similar action is then exerted successively on the following rods and free spaces.
On constate que la pression P nécessaire pour ouvrir la totalité des joncs est identique à la pression nécessaire pour ouvrir le premier jonc. It can be seen that the pressure P necessary to open all of the rods is identical to the pressure necessary to open the first rod.
Cette pression est largement inférieure à la pression qui serait nécessaire à l'ouverture d'une surface de contact égale à la somme des surfaces de contact de l'ensemble des joncs. This pressure is much lower than the pressure that would be required to open a contact surface equal to the sum of the contact surfaces of all the rods.
A titre d'exemple la pression nécessaire à l'ouverture d'un jonc 13 offrant une extension longitudinale de la surface de contact annulaire de 0.8 mm avec la partie rigide 7 varie de 100 à 300 millibars suivant les diamètres relatifs et le serrage existant entre ces deux pièces . By way of example, the pressure required to open a rod 13 offering a longitudinal extension of the annular contact surface of 0.8 mm with the rigid part 7 varies from 100 to 300 millibars depending on the relative diameters and the tightening existing between these two pieces.
En supposant la réalisation de 4 joncs 13 de dimensions identiques, l'extension longitudinale de la surface de contact entre les deux parties souple 8 et rigide 7 continue équivalente serait de 3.2 mm et la pression nécessaire à son ouverture rédhibitoire avec un fonctionnement normal du dispositif. Assuming the production of 4 rods 13 of identical dimensions, the longitudinal extension of the contact surface between the two flexible 8 and rigid 7 equivalent equivalent parts would be 3.2 mm and the pressure necessary for its opening prohibitive with normal operation of the device .
On a ainsi réalisé un dispositif dont l'embout distributeur 15 exerce une résistance efficace à l'entrée des bactéries de l'extérieur vers l'intérieur du récipient 1 grâce à une surface de contact entre les parties souple 8 et rigide 7 suffisante mais ne nécessitant qu'une pression réduite à son bon fonctionnement . A device has thus been produced, the dispensing nozzle 15 of which exerts effective resistance to the entry of bacteria from the outside towards the inside of the container 1 thanks to a sufficient contact surface between the flexible 8 and rigid 7 parts but does not requiring reduced pressure for proper operation.
La résistance absolue à la progression des bactéries par des zones de contact étanches entre deux parties souple et rigide est illusoire et le but d' un dispositif tel que décrit précédemment est de s'opposer le plus longtemps possible à cette progression vers l'intérieur du récipient vers lequel ces bactéries sont attirées et qui doit rester stérile. The absolute resistance to the progression of bacteria by sealed contact zones between two flexible and rigid parts is illusory and the purpose of a device as described above is to oppose this progression towards the interior as long as possible. container to which these bacteria are attracted and which must remain sterile.
L'expérience a montré que plusieurs joncs étaient nécessaires à une résistance efficace à la progression des bactéries. Lorsque les bactéries ont réussi à pénétrer dans le premier espace libre 14 elles se multiplient et on doit donc essayer de minimiser le volume de cet espace de manière à limiter le nombre de ces bactéries. On a ainsi représenté, sur la figure 6, un espace libre réduit à un secteur angulaire et ne s'étendant pas sur 360° comme représenté sur la figure 5.Experience has shown that several rods are necessary for effective resistance to the progression of bacteria. When the bacteria have successfully entered the first free space 14 they multiply and one must therefore try to minimize the volume of this space so as to limit the number of these bacteria. FIG. 6 shows a free space reduced to an angular sector and does not not extending over 360 ° as shown in Figure 5.
La construction décrite, qui s'apparente à un joint labyrinthique (en anglais : « labyrinth seal ») , répond à cet objectif et le nombre de joncs, leur forme, leurs dimensions ainsi que celles des espaces libres entre lesdits joncs peut varier sans sortir du cadre de 1' invention . The construction described, which is similar to a labyrinth seal (meets in English: "labyrinth seal"), meets this objective and the number of rods, their shape, their dimensions as well as those of the free spaces between said rods can vary without leaving of the scope of the invention.
