Definitions
- the present invention relates to a dispenser of more or less viscous fluid such as cream, gel, paw, lotion, perfume, etc.
- This dispenser comprises a fluid reservoir of variable volume in which the fluid product is stored out of contact with air.
- the reservoir is provided with an actuating wall axially displaceable back and forth between a rest position and a depressed position. The displacement of the wall varies the pressure inside the tank between vacuum phases and overpressure phases.
- the wall is located on one side of the dispenser.
- the dispenser comprises a dispensing orifice through which the fluid product is dispensed from the dispenser.
- the orifice is provided with a non-return check valve which prevents air from being drawn into the tank. This type of distributor is frequently found in the fields of perfumery, cosmetics, pharmacy and parapharmacy.
- the actuating wall is located near the dispensing orifice so that the depression of the actuating wall has the direct effect of putting the fluid product stored in the reservoir under pressure so that it is forced through the dispensing orifice.
- the outlet valve closes: the reservoir is then subjected to a depression, which has the effect of modifying its useful volume.
- This variation in useful volume can be effected for example because the reservoir is made from a deformable flexible bag.
- the reservoir forms a sliding shaft in which is engaged a follower piston.
- the depression has the effect of deforming the flexible pouch that will shrivel on itself.
- the object of the present invention is to provide a dispenser of this type having a configuration that avoids this design constraint.
- the present invention proposes that the dispensing orifice is located on one side of the distributor other than that where the actuating wall is located.
- the fluid dispenser comprises a bottom and a top, when positioned upright, the actuating wall being located at the bottom, the distributor resting, in the rest position and in the depressed position, on the actuating wall. .
- the actuation of the dispenser can thus be performed by pressing the dispenser, while its bottom rests on a bearing surface.
- the product is dispensed on the top or side of the dispenser.
- the reservoir forms a sliding shaft in which a follower piston is slidably mounted. This is an embodiment for making a reservoir of variable volume.
- the configuration is paradoxical, because it should be noted that the actuating wall does not act directly on the follower piston. but on the fluid product.
- the follower piston is at the bottom, and the orifice and the actuating wall at the top.
- a difficulty overcome by the present invention is to decouple the orifice and the actuating wall, while using a follower piston. And to do this, the follower piston can form a connecting conduit which communicates the reservoir with the dispensing orifice. It should first be noted that this characteristic can be implemented independently of the fact that the actuating wall is opposite or uncoupled from the dispensing orifice. However, the combination of these two features is advantageous.
- the follower piston does not communicate directly with the dispensing orifice.
- the follower piston is generally located at the bottom of the tank and it moves by suction towards the dispensing orifice.
- the originality of this feature lies in the fact that the follower piston connects the reservoir to the dispensing orifice.
- the wall and the follower piston move along a common axis X. They are separated by the fluid product stored in the reservoir. At each depression of the wall, fluid is dispensed and the follower piston remains static and at each release of the wall the follower piston moves.
- the conduit is in leaktight sliding engagement with a sleeve integral with the dispensing orifice, the conduit and the sleeve sliding relative to each other as the follower piston moves in the barrel.
- the barrel, the sleeve and the dispensing orifice are formed by a one-piece body.
- the body comprises an upper plate forming the top of the dispenser, the plate being formed with a hole which is advantageously provided with an outlet valve, so as to form together the dispensing orifice.
- the dispenser can be made from only three parts, namely the one-piece body, the follower piston and the actuating wall, if the outlet valve is omitted.
- the dispenser may comprise a one-piece body internally defining the fluid reservoir, the body being closed by a bottom forming the actuating wall.
- the reservoir is mainly formed by the bottom, the body and a follower piston, this follower piston being positioned between the bottom and the dispensing orifice.
- the body forms a sleeve integral with the dispensing orifice, the follower piston forming a duct engaged in leaktight sliding in the sleeve, the reservoir thus communicating with the dispensing orifice through the duct and the sleeve.
- FIG. 1 is a view in vertical cross-section through a fluid dispenser according to the invention in the rest state
- FIGS. 2a, 2b and 2c represent the dispenser of FIG. different phases of the operating cycle of the dispenser
- - Figure 3 is a view similar to that of Figure 1 for an alternative embodiment of the invention
- Figure 4 is a view similar to that of Figure 3 for another variant embodiment of the invention.
- the fluid dispenser according to the invention essentially comprises three component parts, namely a body 1, a bottom 2 and a follower piston 3.
- the distributor also comprises an outlet valve 4 or an attached nozzle.
- the dispenser may furthermore also be provided with a protective cover 5 which is removably mounted on the dispenser so as to mask the dispensing orifice.
- the body 1 is preferably made integrally of plastics material and comprises a barrel 11 of cylindrical shape, preferably circular, within which slides the follower piston 3, as will be seen below.
- the barrel 11 includes an open bottom end and an upper end which forms a shoulder 12 inwardly.
- the body 21 extends from this shoulder 12 upwards to form a ring 13 which can advantageously be used for fixing the protective cover 5.
- the body 1 forms a plate 14 which is here substantially circular.
- This plate 14 is substantially flat or concave and has a substantially central hole which will serve to define the dispensing orifice.
- a sleeve 16 extends from the hole towards the inside of the body so that the ring 13 extends concentrically with this sleeve 16. The lower end of the sleeve 16 extends to the level of the barrel 11
- the plate 14 at the substantially central hole defines a hooking structure 144 which retains the valve 4.
- any outlet valve in the context of this invention for example can be used a valve in the form of a mushroom or umbrella comprising an anchor foot 41 engaged in the attachment structure 144 and a washer or corolla 42 whose edge comes into selective waterproof support on a valve seat 15 formed at the junction of the plate 14 with the sleeve 13 which defines the hole.
- the foot 41 can be fixed in place inside the attachment structure 144: in this case, the washer 42 is elastically deformable.
- the anchor foot 41 can move on a limited stroke inside the attachment structure 144: in this case, the washer 42 does not need to be elastically deformable.
- the protective cover 5 comprises a peripheral skirt 51 intended to come into frictional engagement, latching or screwing with the crown 13 and a cover wall 52 which covers the plate 14, with its central hole and its valve 4.
- the cover protection 5 can be entirely removed from the body 1, or alternatively, the cover can be hinged to the body.
- the cover 5 is made integrally with the body and connected thereto by a bridge of deformable material.
- the follower piston 3 conventionally comprises a sealing lip 31, which here is of the type with a double sealing contact.
- the sealing lip 31 is connected to a roof 32 which extends in its center by a axial conduit 33 which is open at both ends.
- the conduit 33 comprises a free end opposite the roof 32 and which forms a leaktight sliding lip 34.
- the conduit 33 is engaged inside the sleeve 16 so that the lip 34 can slide in a sealed manner inside the sleeve 16. It can also be envisaged that the conduit 33 is arranged around the sleeve 16: in this case, it is the free end of the sleeve 16 which is then provided with a sealing lip.
- the sealing lip 31 of the follower piston is engaged in leaktight sliding inside the barrel 11 of the body 1. In the initial starting position, the lip 31 is located in the upper part of the barrel 11. As and when of the use of the dispenser, this lip 31 will move towards the bottom of the barrel 11.
- the bottom 2 of the distributor is sealingly engaged in the open lower end of the barrel 11.
- the bottom 2 comprises a rigid annular cup 21 which is anchored on its outer periphery 22 in a sealed manner in the barrel 11.
- the inner periphery of the cup 21 is connected to a membrane 24 having a fixing heel connected to the cup.
- This elastically deformable membrane 24 is in the form of an annular dome which is closed at its center by an actuating wall 25.
- This wall 25 is situated substantially centrally with respect to the bottom 2 of the distributor.
- This actuating wall 25 is axially displaceable back and forth by deforming the flexible membrane 24. In Figure 1, the actuating wall 25 is in its rest position.
- the bottom 2 can be made integrally with a single plastic material.
- the bottom 2 can be made by bi-injection or co-molding from two different plastics.
- the bottom, and thus the actuating wall are in direct contact with the fluid, so that they form a tank wall element.
- the dispenser In FIG. 1, the dispenser is in its rest position with the reservoir 10 filled to the maximum, the lip 31 of the follower piston being in abutment with the shoulder 12.
- the valve 4 is closed so that there is no no dispensing orifice.
- the lip 34 is at its highest point in the sleeve 16. From this initial rest position, will now be described, with reference to Figures 2a, 2b and 2c a complete operating cycle of the dispenser according to the invention.
- the first step is to remove the cover 5, as shown in Figure 2a.
- the distribution of fluid product then stops at this moment and as soon as the pressure is released on the actuating wall 25, the valve 4 closes so that there is again no more orifice. 150.
- the wall 25 then returns to its initial rest position under the effect of the membrane 24 which tends to return to its original starting position because of its elastic shape memory.
- the membrane 24 therefore plays a role of return spring.
- the actuating wall 25 generates a depression inside the tank 10, which has the effect of sucking the follower piston 3 which then moves with a leaktight sliding inside. of the drum.
- the displacement of the follower piston is represented in FIG. 2b by the two arrows on either side of the duct 33.
- the follower piston makes a fluid connection between the reservoir 10 and the dispensing orifice.
- This fluidic connection makes it possible to produce a distributor without air intake whose reciprocating movable actuating wall is clearly separated from the dispensing orifice, and even situated on the opposite side.
- the actuating wall 25 is movable between two extreme positions, the fluid dispensing is perfectly metered. This produces a metering distributor without air intake whose actuating wall is located at the bottom and the dispensing orifice at the top. It is the follower piston itself which provides the connection between the reservoir and the dispensing orifice.
- FIG. 3 shows an alternative embodiment in which the follower piston 3 and the bottom 2 may be similar or identical to those of the first embodiment.
- the body 1 also comprises a shaft 11, a ring 13, a plate 14 and a sleeve 16, but it further comprises a dispensing nozzle 17 which terminates in a dispensing orifice 150.
- This dispenser also comprises a valve 4.
- the dispensing orifice 150 can also be made using a nozzle allowing a swirling of the fluid product.
- This nozzle can be integrated into the body 1 or made in the form of an insert.
- the dispenser of FIG. 3 comprises three constituent parts, namely the body 1, the bottom 2 and the follower piston 3.
- This dispenser can be used with the aid of a single hand in the manner of a syringe, disposing of the index finger and the middle finger on the plate 14 on the front part of the tip 17 and the thumb on the actuating wall 25.
- the dispensing of fluid product is perfectly dosed and the actuating wall returns to each actuation in its initial resting position.
- Such a dispenser may for example be used in pharmacies for the injection of various fluids into the natural orifices, such as nostrils or ears.
- the shown dispenser differs from that of FIG. 3 essentially at the end of the end piece 17 and its bottom 2.
- the end piece here is no longer axial, but instead lateral.
- the dispensing orifice 150 is formed by a slotted shutter which opens under the pressure of the fluid product.
- the actuating wall 25 projects downwards and can thus constitute a bearing surface of the dispenser. It is of course still possible to imagine other embodiments in which the actuating wall is located at the bottom of the dispenser, but on the side or the top. Similarly, the follower piston 3 can move horizontally.
