Description

Distributeur de produit fluide rechargeable Refillable fluid dispenser
La présente invention concerne un distributeur de produit fluide rechargeable comprenant un réservoir de produit fluide définissant un col et un orifice de remplissage. Le distributeur comprend également un organe de distribution, tel qu’une pompe, monté sur le col du réservoir de produit fluide pour prélever du produit fluide, ainsi qu’un clapet de remplissage. Le distributeur définit une chambre séparant l’orifice de remplissage du clapet de remplissage. The present invention relates to a refillable fluid product dispenser comprising a fluid product reservoir defining a neck and a filling orifice. The dispenser also includes a dispensing member, such as a pump, mounted on the neck of the fluid reservoir for withdrawing fluid, as well as a filling valve. The distributor defines a chamber separating the filling port from the filling valve.
Le domaine d’application privilégié de la présente invention est celui de la parfumerie, sans oublier la cosmétique ou encore la pharmacie. The preferred field of application of the present invention is that of perfumery, without forgetting cosmetics or even pharmacy.
Dans l’art antérieur, on connaît déjà de nombreux distributeurs rechargeables que l’on désigne souvent sous le terme de « distributeur nomade ». Ils comprennent un réservoir de volume réduit, de l’ordre de 5 à 20 ml, et sont remplissables à l’aide d’une source de produit fluide apte à injecter du produit fluide sous pression à travers l’orifice de remplissage, de sorte que la pression du produit fluide ouvre le clapet de remplissage pour que le produit fluide injecté puisse remplir le réservoir. La source comprend en général une tige de soupape qui est appliquée contre le bord extérieur de l’orifice de remplissage. A chaque poussée de la tige soupape contre l’orifice de remplissage, une dose de produit fluide est injectée. In the prior art, many rechargeable dispensers are already known, which are often referred to as "nomadic dispensers". They include a reservoir of reduced volume, of the order of 5 to 20 ml, and can be filled using a source of fluid product capable of injecting fluid product under pressure through the filling orifice, so that the pressure of the fluid product opens the filling valve so that the injected fluid product can fill the reservoir. The source typically includes a valve stem which is pressed against the outer edge of the fill port. Each time the valve stem pushes against the filling orifice, a dose of fluid is injected.
A la fin de l’opération de remplissage, la tige de soupape est éloignée de l’orifice de remplissage, mais une petite quantité de produit fluide reste présent au niveau de l’orifice de remplissage. Parfois, une petite goutte peut s’en séparer. Ce produit fluide résiduel peut alors souiller un objet mis en contact de l’orifice de remplissage ou sur lequel la petite goutte va tomber. At the end of the filling operation, the valve stem is moved away from the fill port, but a small amount of fluid remains at the fill port. Sometimes a small drop can separate from it. This residual fluid product can then soil an object placed in contact with the filling orifice or on which the small drop will fall.
Il existe donc un problème de propreté au niveau de l’orifice de remplissage avec ces distributeurs nomades. C’est d’ailleurs une des raisons majeures pour laquelle ils ne sont pas plus répandus dans le commerce. L’utilisateur ne veut pas répandre son parfum dans toutes ses affaires, et en particulier celles de son sac à main, puisque les distributeurs nomades sont souvent transportés dans les sacs à main. There is therefore a problem of cleanliness at the level of the filling orifice with these nomadic dispensers. This is also one of the major reasons why they are not more widespread in the trade. The user does not want to spread his perfume in all his belongings, and in especially those of his handbag, since nomadic distributors are often carried in handbags.
La présente invention a pour but de remédier à ce problème persistant de propreté des distributeurs nomades de l’art antérieur. L’orifice de remplissage doit rester propre et donc exempt de produit fluide après chaque opération de remplissage. The object of the present invention is to remedy this persistent problem of cleanliness of nomadic distributors of the prior art. The filling orifice must remain clean and therefore free of fluid after each filling operation.
Pour atteindre ce but, la présente invention propose que la chambre, située entre l’orifice de remplissage et le clapet de remplissage, comprenne des moyens de rétention pour retenir le produit fluide à l’intérieur de la chambre. Ainsi, il n’y a presque pas ou plus du tout de produit fluide au niveau de l’orifice de remplissage, qui reste donc propre. To achieve this goal, the present invention proposes that the chamber, located between the filling orifice and the filling valve, include retention means for retaining the fluid product inside the chamber. Thus, there is hardly any fluid or any more at all at the level of the filling orifice, which therefore remains clean.
Avantageusement, le clapet de remplissage est un clapet hydraulique qui s’ouvre sous l’action du produit fluide injecté sous pression à travers l’orifice de remplissage et la chambre. Le produit fluide sous pression pénètre donc dans la chambre à travers l’orifice de remplissage et soulève le clapet de remplissage pour atteindre le réservoir. Advantageously, the filling valve is a hydraulic valve which opens under the action of the fluid product injected under pressure through the filling orifice and the chamber. The pressurized fluid therefore enters the chamber through the filling orifice and lifts the filling valve to reach the reservoir.
Selon une forme de réalisation, le clapet de remplissage peut comprendre un insert formant un siège de clapet et un organe mobile qui vient en contact étanche sélectif avec le siège de clapet. D’autre part, le réservoir peut comprendre un fond formant l’orifice de distribution, l’insert étant monté sur le fond en formant entre eux la chambre. Ainsi, on peut dire que la chambre est un espace tampon entre l’orifice de remplissage et le clapet de remplissage. Avantageusement, le fond forme un conduit d’entrée définissant l’orifice de remplissage et une entrée dans la chambre. According to one embodiment, the filling valve may comprise an insert forming a valve seat and a movable member which comes into selective sealed contact with the valve seat. On the other hand, the reservoir may include a bottom forming the dispensing orifice, the insert being mounted on the bottom forming the chamber between them. Thus, it can be said that the chamber is a buffer space between the filling port and the filling valve. Advantageously, the bottom forms an inlet duct defining the filling orifice and an inlet into the chamber.
Selon un premier mode de réalisation, les moyens de rétention peuvent comprendre un dispositif anti-goutte situé à proximité de l’orifice de remplissage. Avantageusement, le dispositif anti-goutte peut comprendre une membrane souple fendue qui s’ouvre sous l’action du produit fluide injecté sous pression à travers l’orifice de remplissage et qui reste fermée et étanche au repos. Il est possible que la membrane souple fendue repose à l’état de repos directement contre l’entrée. Le dispositif anti-goutte peut être maintenu en place par coincement entre le fond et l’insert fixe. En variante, le maintien en position du dispositif anti-goutte peut aussi être assuré par une pièce intercalaire. According to a first embodiment, the retention means may comprise an anti-drip device located near the filling orifice. Advantageously, the anti-drip device can comprise a split flexible membrane which opens under the action of the fluid product injected under pressure through the filling orifice and which remains closed and sealed when at rest. It is possible that the flexible split membrane rests in the resting state directly against the inlet. The anti-drip device can be held in place by wedging between the base and the fixed insert. As a variant, the maintenance in position of the anti-drip device can also be ensured by an intermediate piece.
Selon un deuxième mode de réalisation, la chambre peut être à volume variable entre un volume maximal à l’état de repos et un volume minimal lorsqu’une pression est exercée au niveau de l’orifice de remplissage, créant ainsi un effet d’aspiration du produit fluide vers l’intérieur de la chambre, lorsque cette dernière retourne dans son état de repos. La variation de volume de la chambre peut provenir d’une déformation du fond et/ou d’un coulissement entre le fond et l’insert. Avantageusement, le conduit d’entrée définit un volume qui est inférieur à la variation de volume de la chambre, de manière à garantir le vidage du conduit d’entrée. Sinon, il est préférable que le conduit d’entrée soit long et fin pour augmenter la capillarité. According to a second embodiment, the chamber may have a variable volume between a maximum volume in the state of rest and a minimum volume when pressure is exerted at the level of the filling orifice, thus creating a suction effect. of the fluid product towards the interior of the chamber, when the latter returns to its rest state. The variation in the volume of the chamber may come from a deformation of the bottom and / or from a sliding between the bottom and the insert. Advantageously, the inlet duct defines a volume which is less than the variation in volume of the chamber, so as to ensure the emptying of the inlet duct. Otherwise, it is preferable that the inlet duct be long and thin to increase capillarity.
Selon un troisième mode de réalisation, la chambre contient une matière spongieuse qui est exprimée sous l’action du produit fluide injecté sous pression dans la chambre et qui s’imprégne de produit fluide la pression retombe dans la chambre. La matière spongieuse peut par exemple remplir la chambre, à l’exception d’un passage central qui relie directement l’orifice de remplissage au clapet de remplissage. A chaque injection de produit fluide sous pression dans la chambre, la matière spongieuse est écrasée et dégorge son contenu de produit fluide et dès que la pression revient à la normale, la matière spongieuse se détend et s’imbibe du produit fluide resté dans la chambre. According to a third embodiment, the chamber contains a spongy material which is expressed under the action of the fluid product injected under pressure into the chamber and which is impregnated with the fluid product, the pressure falling back into the chamber. The spongy material can, for example, fill the chamber, with the exception of a central passage which directly connects the filling port to the filling valve. With each injection of pressurized fluid product into the chamber, the spongy material is crushed and disgorges its fluid content and as soon as the pressure returns to normal, the spongy material relaxes and soaks up the fluid product remaining in the chamber .
Dans les trois modes de réalisation, le produit fluide est retenu dans la chambre, de manière à empêcher l’alimentation en retour de l’orifice de remplissage en produit fluide. L’invention s’applique aux fluides de toutes viscosités, du parfum aux produits cosmétiques. Elle permet aussi de retarder ou d’empêcher le séchage des produits cosmétiques. In all three embodiments, the fluid is retained in the chamber, so as to prevent the backflow of fluid to the fill port. The invention applies to fluids of all viscosities, from perfume to cosmetic products. It also helps to delay or prevent the drying of cosmetic products.
L’invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d’exemples non limitatifs, plusieurs modes de réalisation de l’invention. The invention will now be more fully described with reference to the accompanying drawings giving, by way of non-limiting examples, several embodiments of the invention.

The dispenser comprises the following constituent elements, namely a fluid reservoir R, a dispenser member P, a fixing ring F, a pusher B, a filling valve 2, 3 and a vent valve 5, 6.
Le réservoir de produit fluide R comprend un fût R1 qui est globalement cylindrique. A son extrémité supérieure, le fût R1 définit un col R2. Le fût R1 peut être réalisé en verre transparent. A son extrémité inférieure R3, le fût R1 est pourvu d’un fond de réservoir 1 définissant un orifice de remplissage 10. Ce fond 1 sert de support au clapet de remplissage, qui comprend un insert fixe 2 et un organe mobile 3. Une chambre C est définie conjointement par le fond 1 et l’insert fixe 2 entre l’orifice de remplissage 10 et l’organe mobile 3. The fluid reservoir R comprises a barrel R1 which is generally cylindrical. At its upper end, the barrel R1 defines a neck R2. The barrel R1 can be made of transparent glass. At its lower end R3, the barrel R1 is provided with a tank bottom 1 defining a filling orifice 10. This bottom 1 serves as a support for the filling valve, which comprises a fixed insert 2 and a movable member 3. A chamber C is defined jointly by the bottom 1 and the fixed insert 2 between the filling orifice 10 and the movable member 3.
Plus précisément, le fond 1 est une pièce rapportée dans l’extrémité inférieure R3 du fût R1. Le fond 1 peut être réalisé en matière plastique. Il comprend un manchon 11 engagé en force et de manière étanche dans l’extrémité inférieure R3 du fût. Un épaulement annulaire 12 repose sur le bord annulaire libre de l’extrémité inférieure R3.

La couronne 14 fait saillie vers l’intérieur du réservoir R, alors que le téton 15 fait saillie de manière opposée vers l’extérieur. Le téton 15 forme un conduit d’entrée 16 qui définit l’orifice de remplissage 10 côté extérieur et une entrée 17 côté intérieur. L’orifice de remplissage 10 est situé au fond d’une coupelle 18, adaptée à recevoir l’extrémité libre de la tige de soupape S (représentée en traits pointillés) d’une source de produit fluide. Le passage interne de la tige de soupape S est ainsi automatiquement aligné avec l’orifice de remplissage 10. More precisely, the base 1 is a part attached to the lower end R3 of the barrel R1. The bottom 1 can be made of plastic. It comprises a sleeve 11 forcefully engaged in leaktight manner in the lower end R3 of the barrel. An annular shoulder 12 rests on the free annular edge of the lower end R3. The bottom 1 forms an annular flange 13 which connects the sleeve 11 and the annular shoulder 12 to a ring 14 and a stud 15. The ring 14 projects towards the inside of the reservoir R, while the stud 15 protrudes so opposite to the outside. The stud 15 forms an inlet duct 16 which defines the filling orifice 10 on the exterior side and an inlet 17 on the interior side. The filling orifice 10 is located at the bottom of a cup 18, adapted to receive the free end of the valve stem S (shown in dotted lines) from a source of fluid. The passage internal valve stem S is thus automatically aligned with the filling port 10.
L’insert fixe 2 du clapet de remplissage est monté, par exemple par encliquetage sur le fond 1. Il comprend une jupe externe 25 qui est en prise dans le manchon 11 du fond 1 et une douille 23 en prise avec la couronne 14 du fond 1 . Une de ces deux prises, voire les deux, peuvent être étanches. L’insert 2 forme également un logement central 24 qui est entouré par une ou plusieurs ouvertures 22, elles-mêmes entourées par un siège de clapet annulaire 21 . The fixed insert 2 of the filling valve is mounted, for example by snap-fastening on the base 1. It comprises an outer skirt 25 which is engaged in the sleeve 11 of the base 1 and a sleeve 23 in engagement with the crown 14 of the base 1. One of these two sockets, or both, can be waterproof. The insert 2 also forms a central housing 24 which is surrounded by one or more openings 22, themselves surrounded by an annular valve seat 21.
L’organe mobile 3 du clapet de remplissage est monté sur l’insert fixe 2. Il comprend une corolle souple 31 qui vient sélectivement en appui étanche sur le siège de clapet 21 de l’insert 2. L’organe mobile 3 comprend aussi un talon d’ancrage 32 qui est engagé dans le logement central 24. Au repos, le clapet de remplissage est naturellement fermé. Lorsque du produit fluide sous pression passe par les ouvertures 22, il soulève la corolle 31 en la déformant élastiquement. Dès que la pression retombe en-dessous d’un seuil prédéterminé, la corolle 31 revient en contact étanche sur son siège 21 . The movable member 3 of the filling valve is mounted on the fixed insert 2. It comprises a flexible corolla 31 which selectively bears tightly on the valve seat 21 of the insert 2. The movable member 3 also comprises a anchoring heel 32 which is engaged in the central housing 24. At rest, the filling valve is naturally closed. When the pressurized fluid product passes through the openings 22, it lifts the corolla 31 by deforming it elastically. As soon as the pressure drops below a predetermined threshold, the corolla 31 returns in sealed contact on its seat 21.
Le fond 1 et l’insert fixe 2 forment entre eux une chambre C par laquelle le produit fluide chemine en entrant par le conduit d’entrée 16 et en sortant par le passage créé entre la corolle 31 et son siège 21 . Cette chambre C est donc amenée à être constamment remplie de produit fluide. Une fuite est donc possible à travers le conduit d’entrée 16 et l’orifice de remplissage 10. The bottom 1 and the fixed insert 2 form between them a chamber C through which the fluid travels entering through the inlet duct 16 and exiting through the passage created between the corolla 31 and its seat 21. This chamber C is therefore caused to be constantly filled with fluid. A leak is therefore possible through the inlet duct 16 and the filling port 10.
Selon l’invention, la chambre C comprend des moyens de rétention pour retenir le produit fluide à l’intérieur de la chambre. Ainsi, il n’y a presque pas ou plus du tout de produit fluide au niveau de l’orifice de remplissage, qui reste donc propre. Ces moyens de rétention peuvent présenter différentes formes de réalisation. Ils peuvent agir par obturation, aspiration ou imprégnation. According to the invention, the chamber C comprises retention means for retaining the fluid product inside the chamber. Thus, there is hardly any fluid or any more at all at the level of the filling orifice, which therefore remains clean. These retention means can have different embodiments. They can act by obturation, suction or impregnation.
Selon un premier mode de réalisation représenté sur les figures 1 et 2, les moyens de rétention comprennent un dispositif anti-goutte 4 situé à proximité de l’orifice de remplissage 10. Le dispositif anti-goutte 4 comprend une membrane souple fendue 41 qui s’ouvre sous l’action du produit fluide injecté sous pression à travers l’orifice de remplissage 10 et qui reste fermée et étanche au repos. Le dispositif anti-goutte 4 comprend une bague de fixation 42 qui être maintenue en place par coincement entre le téton 15 du fond 1 et la douille 23 de l’insert fixe 2. Le coincement de la bague 42 peut assurer l’étanchéité de la chambre C entre le fond 1 et l’insert 2. Ce dispositif anti goutte 4 agit donc à la manière d’un obturateur ou d’un clapet, mais avec un seuil d’ouverture très faible, qui ne génère que très peu de perte de charge. En effet, le produit fluide injecté sous pression à travers le conduit d’entrée 16 ne doit pas être gêné par la membrane souple fendue 41 , qui doit s’ouvre facilement et rapidement. Sa fonction n’est pas de supporter des pressions ou des dépressions, mais simplement de retenir le produit fluide dans la chambre C qui est à la pression atmosphérique, une fois l’injection de produit fluide terminée. On peut considérer que le dispositif anti-goutte 4 a pour fonction physique de créer une perte de charge suffisante au repos pour empêcher le produit fluide de fuir par le conduit d’entrée 16. Une étanchéité parfaite n’est pas exigée. According to a first embodiment shown in Figures 1 and 2, the retention means comprise an anti-drip device 4 located near the filling orifice 10. The anti-drip device 4 comprises a split flexible membrane 41 which s '' opens under the action of the fluid product injected under pressure through the filling orifice 10 and which remains closed and waterproof at rest. The anti-drip device 4 comprises a fixing ring 42 which is held in place by wedging between the stud 15 of the bottom 1 and the sleeve 23 of the fixed insert 2. The wedging of the ring 42 can ensure the sealing of the gasket. chamber C between the bottom 1 and the insert 2. This anti-drip device 4 therefore acts in the manner of a shutter or a valve, but with a very low opening threshold, which generates very little loss dump. In fact, the fluid product injected under pressure through the inlet duct 16 must not be hampered by the flexible split membrane 41, which must open easily and quickly. Its function is not to withstand pressures or depressions, but simply to retain the fluid product in the chamber C which is at atmospheric pressure, once the injection of fluid product is completed. It can be considered that the anti-drip device 4 has the physical function of creating a sufficient pressure drop at rest to prevent the fluid product from leaking through the inlet duct 16. Perfect sealing is not required.
En variante représentée sur la figure 3, le dispositif anti-goutte 4’ se présente sous la forme d’un simple disque souple fendu qui est maintenu en place sur sa périphérie par une douille rallongée 23’ de l’insert 2’, qui appuie le disque souple fendu sur une paroi de fond plane 19 de la chambre C’. Il faut remarquer que le disque souple fendu 4’ repose à l’état de repos directement contre l’entrée 17 du conduit d’entrée 16. Ainsi, seul le contenu du conduit d’entrée 16 est susceptible de fuir, mais comme son volume est extrêmement faible, la fuite sera imperceptible. In a variant shown in Figure 3, the anti-drip device 4 'is in the form of a simple split flexible disc which is held in place on its periphery by an extended sleeve 23' of the insert 2 ', which supports the flexible disc split on a flat bottom wall 19 of the chamber C '. It should be noted that the split flexible disc 4 'rests in the rest state directly against the inlet 17 of the inlet duct 16. Thus, only the content of the inlet duct 16 is liable to leak, but like its volume is extremely low, the leak will be imperceptible.
Selon un deuxième mode de réalisation représenté sur la figure 4, la chambre C” est à volume variable entre un volume maximal à l’état de repos et un volume minimal lorsqu’une pression est exercée sur le téton 15” au niveau de l’orifice de remplissage 10, créant ainsi un effet d’aspiration du produit fluide vers l’intérieur de la chambre C”, lorsque cette dernière retourne dans son état de repos. La variation de volume de la chambre C” résulte d’une déformation du fond 1 ” et/ou d’un coulissement entre le fond 1 ” et l’insert 2”. Plus précisément, la bride annulaire 13” du fond 1 ” présente une épaisseur de paroi réduite, de sorte qu’elle est élastiquement déformable, ne serait-ce que très faiblement. Ainsi, lorsque la tige de soupape S est appuyée contre la coupelle 18, le téton 15” est déplacé par rapport au manchon 11 et à l’insert 2. Le déplacement du téton 15” induit un coulissement étanche entre la douille 23” et la couronne 14”. Il s’ensuit une diminution de volume de la chambre C”. Dès que la pression est relâchée sur la téton 15”, celui-ci revient dans sa position initiale de repos, ce qui entraine une augmentation de volume de la chambre C”. Mais comme le clapet de remplissage est déjà refermé, le produit fluide présent dans le conduit d’entrée 16” est aspiré à l’intérieur de la chambre C”, laissant ainsi le conduit d’entrée 16” et l’orifice de remplissage exempt de produit fluide. Avantageusement, le conduit d’entrée 16” définit un volume qui est inférieur à la variation de volume de la chambre C”, de manière à garantir le vidage du conduit d’entrée 16”. Sinon, il est préférable que le conduit d’entrée 16” soit long et fin pour augmenter sa capillarité. According to a second embodiment shown in FIG. 4, the chamber C ”has a variable volume between a maximum volume in the state of rest and a minimum volume when pressure is exerted on the stud 15” at the level of the filling orifice 10, thus creating a suction effect of the fluid product towards the interior of the chamber C ”, when the latter returns to its rest state. The variation in the volume of chamber C ”results from a deformation of the base 1” and / or a sliding between the base 1 ”and the insert 2”. More precisely, the annular flange 13 ”of the bottom 1” has a reduced wall thickness, so that it is elastically deformable, even that very weakly. Thus, when the valve stem S is pressed against the cup 18, the 15 ”stud is moved relative to the sleeve 11 and the insert 2. The displacement of the 15” stud induces a tight sliding between the 23 ”sleeve and the 14 ”crown. This results in a decrease in the volume of chamber C ”. As soon as the pressure is released on the 15 ”stud, it returns to its initial rest position, which leads to an increase in the volume of the C” chamber. But as the filling valve is already closed, the fluid present in the 16 ”inlet duct is sucked inside the C” chamber, thus leaving the 16 ”inlet duct and the filling orifice free. of fluid product. Advantageously, the inlet duct 16 ”defines a volume which is less than the variation in volume of the chamber C”, so as to guarantee the emptying of the inlet duct 16 ”. Otherwise, it is preferable that the 16 ”inlet duct be long and thin to increase its capillarity.
Selon un troisième mode de réalisation représenté sur la figure 5, la chambre C’” contient une matière spongieuse 4”’ qui est exprimée sous l’action du produit fluide injecté sous pression dans la chambre C’” et qui s’imprègne de produit fluide la pression retombe dans la chambre C’”. La matière spongieuse 4”’ peut par exemple remplir la chambre C’”, à l’exception d’un passage central qui relie directement l’orifice de remplissage 10 au clapet de remplissage. A chaque injection de produit fluide sous pression dans la chambre C’”, la matière spongieuse 4”’ est écrasée et dégorge son contenu de produit fluide et dès que la pression revient à la normale, la matière spongieuse 4”’ se détend et s’imbibe du produit fluide resté dans la chambre C’”. On peut dire que le produit fluide est aspiré et retenu dans la chambre C’” par capillarité à l’intérieur de la masse spongieuse 4”’. Le conduit d’entrée 16”’ est ainsi exempt de produit fluide. According to a third embodiment shown in FIG. 5, the chamber C '”contains a spongy material 4”' which is expressed under the action of the fluid product injected under pressure into the chamber C '”and which is impregnated with the product. fluid pressure drops back into chamber C '”. The spongy material 4 "" can for example fill the chamber C ", with the exception of a central passage which directly connects the filling port 10 to the filling valve. With each injection of pressurized fluid product into chamber C '”, the 4”' spongy material is crushed and disgorges its fluid product content and as soon as the pressure returns to normal, the 4 ”'spongy material relaxes and s 'soaks up the fluid product left in chamber C' ”. We can say that the fluid is sucked and retained in the chamber C "by capillary action inside the spongy mass 4" ". The 16 "" inlet duct is thus free of fluid.
Dans tous les modes de réalisation décrits, la chambre forme ou contient des moyens de rétention du produit fluide à l’intérieur de la chambre qui peuvent même vider le conduit d’entrée, de sorte qu’il n’y a aucun risque de fuite. In all the embodiments described, the chamber forms or contains means for retaining the fluid product inside the chamber which can even empty the inlet duct, so that there is no risk of leakage. .
