Definitions

  • the present invention relates to a fluid dispenser comprising a fluid reservoir containing fluid under pressure, a valve through which the fluid under pressure is discharged, and a dispensing head which cooperates with the valve to dispense fluid through a dispensing orifice.
  • the dispensing head comprises a dispensing tip connected to the valve and defining a supply conduit which connects the valve to the dispensing orifice, as well as a pusher for moving the dispensing tip along an actuation axis X between a rest position in which the valve is closed and a depressed position in which the valve is open.
  • Dispensing continues continuously as long as the plunger remains depressed, and the valve thereby open, the dispensing nozzle being biased towards its rest position by an internal return spring of the valve.
  • This type of dispenser can be described as an aerosol and finds a preferred application in the fields of cosmetics or even pharmacy, without excluding food and household products.
  • a known distributor is presented in US 6,352,184 B1 .
  • a particular type of aerosol implements an outer shell which encloses a flexible bag mounted at the inlet of the valve.
  • a pressurized gas is introduced between the shell and the pocket to pressurize the latter.
  • the fluid product to be dispensed can be introduced under pressure into the flexible bag, so that the fluid product can thus be stored under a pressure of the order of 8 bars at the start and still close to 3 bars when the bag is almost empty.
  • This type of aerosol without propellant gas mixed with the fluid product to be dispensed, is known under the designation of "Bag on Valve" and provides many advantages, such as a total separation between the fluid product and the propellant gas and a restitution approaching 100%.
  • the object of the present invention is to produce a dispenser with discrete or metered dispensing, similar to that of a pump, but from a dispenser of the aerosol type with continuous dispensing, as described above, and in particular an aerosol of bag-on-valve type. More specifically, a problem of the invention is to intervene between the pusher and the dispensing tip so that a conventional press on the pusher generates a short-term dispensing which is independent of the duration of the press on the pusher , but only of the tracking force which is that of a conventional aerosol pusher. In other words, even prolonged pressure on the push-button must produce a spray or a brief, succinct or ephemeral jet, the duration of which is reproducible.
  • the total stroke of the pusher must be at least equal to the limited axial stroke of the dispensing endpiece and preferably slightly or clearly greater, in particular at the end of the stroke, in order to guarantee the release of the dispensing endpiece at the end of its limited axial travel.
  • the pusher can therefore continue its travel after the release of the dispensing nozzle.
  • the pusher can thus remain depressed, but this has no effect on the dispensing of fluid product, given that the valve has already closed.
  • the user can press quite normally on the pusher, without worrying about the length of his press. It is only the support speed that could have a marginal influence on the duration of the distribution.
  • the dispensing nozzle comprises an axial support collar and the limited thrust member comprises at least one axial support profile which selectively comes into engagement with the axial support collar to drive the nozzle distribution on its limited axial stroke.
  • the end of the limited axial travel is characterized by the disengagement of the axial support profile from the axial support collar.
  • the axial support profile is in pressed engagement against the axial support collar only during the limited axial stroke.
  • the thrust release member may comprise cam means for moving said at least one axial bearing profile radially outwards to release the axial bearing collar.
  • said at least one axial support profile can be formed on an elastically deformable tab.
  • the cam means may comprise a conical surface on which the elastically deformable tab slides while deforming radially outwards, at least until the axial bearing flange is released from said at least one axial support profile. The support profile, while pressing axially on the support collar therefore moves outwards under the stress of the conical surface which deforms the elastic tab until the collar escapes from the profile. From this moment, the dispensing nozzle is returned to its rest position by the internal spring of the valve.
  • the conical surface can be formed by a covering part which is fixedly mounted on the reservoir of fluid product, and which advantageously guides the pusher in its axial movement.
  • the dispensing head further comprises a return spring to return the plunger and the limited thrust member to an initial position, this return spring being advantageously formed by the limited thrust member.
  • this return spring being advantageously formed by the limited thrust member.
  • said at least one axial support profile can be located axially away from the axial support flange, when the pusher and the limited thrust member are in the initial position and the dispensing endpiece in the rest position, so that the pusher and the limited thrust member perform an initial idle stroke before said at least one axial support profile comes into contact with the axial support collar.
  • the limited thrust member may comprise several elastically deformable tabs separated by axial slots, each elastically deformable tab internally forming an axial support profile, advantageously in the form of a shoulder facing downwards , the dispensing endpiece comprising an axial section having a connection end connected to the valve and forming the axial support flange, the dispensing endpiece advantageously comprising a transverse section forming the dispensing orifice.
  • the fluid reservoir comprises a flexible pouch pressurized by an external gas.
  • a “Bag on Valve” which is particularly advantageous with the present invention, because the residual pressure in the flexible bag is still high (approximately 3 bars), when it is almost empty. Indeed, this residual pressure makes it possible to generate a dose of fluid product which is substantially identical to or approaching the dose of fluid product when the pocket is full with 8 bars of pressure. With a conventional aerosol with propellant gas mixed with the fluid product to be dispensed, the residual pressure is too low to generate an acceptable dose.
  • the spirit of the invention resides in the fact of decoupling the pusher (on which one presses) from the part (dispensing tip) which directly actuates the valve to release it at a given moment or place of the stroke of the pusher so that the valve can close independently of the pressing force exerted on the pusher. The plunger can then be pressed fully, while the valve is closed again. It is therefore necessary to temporary thrust means for driving the dispensing nozzle and release means for stopping the driving of the dispensing nozzle.
  • the distributor of figure 1 comprises two separate sub-assemblies, namely a fluid reservoir 1 and a dispensing head 3.
  • the dispensing head 3 can be completed with a removable protective cover 8.
  • the fluid reservoir 1 comprises, in this non-limiting embodiment, a rigid outer canister 12 enclosing a flexible pocket 11.
  • the outer canister 12 is provided with a mounting cup 21 on which is mounted a valve 2.
  • the pocket flexible 11 is attached in a sealed manner to the valve 2.
  • the flexible pouch 12 is pressurized by means of a gas G which is present between the container 12 and the pouch 11. Initially, when the pouch 11 is full, the gas G can be at a pressure of the order of 8 to 12 bars, and when the pocket 11 is empty or almost empty, the gas G can still be at a pressure of about 2 to 5 bars.
  • This fluid reservoir 1 is often referred to as a “Bag on Valve”, in the sense that the flexible pouch 11 is (directly or indirectly) mounted on the valve 2. It should be noted that there is no gas thruster inside pocket 11.
  • the valve 2 comprises a receiving housing 22 for the dispensing endpiece 4, as well as a seal 23 which can produce a seal with this dispensing endpiece 4.
  • the valve 2 also comprises a return spring 24 which urges it in a closed state.
  • the dispensing head 3 here comprises four constituent elements, apart from the removable protective cover 8, namely a dispensing endpiece 4, a pusher 5, a limited thrust member 6 and a covering part 7. All these parts can be made by injection/moulding of suitable plastic material.
  • the pusher 5 and the covering part 7 can optionally be made of another material, such as metal for example.
  • the dispensing endpiece 4 is the part which makes it possible to convey the fluid product coming from the valve 2 to a dispensing orifice 41, at the level of which the fluid product leaves the dispenser, for example in the form of a foam, a jet , spray, cord or hazelnut.
  • the dispensing endpiece 4 firstly comprises a connection end 43 which is engaged in a leaktight manner in the housing 22 of the valve 2, being surrounded by the seal 23.
  • This connection end 43 is part of a section axial 44 which forms on its outer periphery an axial bearing flange 46 which projects outwards. It can thus be said that this axial bearing flange 46 forms a shoulder facing upwards.
  • the dispensing nozzle 4 also comprises a transverse section 45 which extends radially outwards from the upper end of the axial section 44.
  • the axial section 44 and the transverse section 45 are crossed by a supply conduit 42 which defines at its downstream end the dispensing orifice 41.
  • the transverse radial section 45 extends substantially at right angles to the axial section 44.
  • the radial section 45 could, however, have other orientations.
  • the dispensing orifice 41 preferably opens laterally.
  • the pusher 5 is a cup-shaped part comprising an upper bearing wall 51 located on the X axis and a peripheral skirt pierced with a notch 52.
  • the pusher 5 also comprises a mounting sleeve 56 which extends towards the down inside the bucket.
  • This sleeve 56 has a perfectly or partially cylindrical shape.
  • the pusher 5 comprises an external attachment profile 53, the function of which will be given below.
  • the pusher 5 does not act directly on the dispensing nozzle 4, but via the limited thrust member 6, which is secured to the pusher 5 via a chimney 65 in engagement with the mounting sleeve 56.
  • the pusher 5 and the limited thrust member 6 could be made in one piece, but for reasons of ease of molding, they are made separately, then reported the one over the other permanently.
  • the limited thrust member 6 also comprises a crown 60 which extends downwards, substantially in the extension of the chimney 65.
  • This crown 60 comprises several elastically deformable lugs 61 which are separated by axial slots 61a.
  • Each tab 61 internally forms an axial support profile 62, in the form of a shoulder facing downwards.
  • Each leg 61 also defines a free sliding end 63.
  • the limited thrust member 6 also comprises leaf springs 64, which here are three in number. Blades 64 extend helically around crown 60. These blades 64 can be replaced by a conventional spring.
  • Trim part 7 is visible in detail on the picture 3a .
  • this trim piece 7 comprises an outer jacket 71 which is pierced with a window 72 for the passage of the dispensing nozzle 4.
  • this jacket 71 may comprise a profile for the attachment of the pusher 5 at its hooking profile 53.
  • the covering part 7 comprises also an annular assembly housing 73 in which the hemmed edge of the cup 21 is received. The covering part 7 then extends radially inwards, forming an annular flange 23, then a conical surface 75.
  • the axial section 44 of the dispensing tip 4 extends inside the crown 60.
  • the axial support profiles 62 are located a short distance axially above the bearing flange 46.
  • the free sliding ends 63 are arranged axially away from the conical surface 75.
  • the transverse section of the dispensing nozzle 4 extends through the notch 52 of the pusher 5 and through the window 72 of the trim piece 7. It can also be seen that the leaf springs 64 rest on the annular flange 74 of the trim piece 7.
  • a user can press on the support surface 51 of the pusher 5 so as to push it along an actuating axis X inside the covering part 7, which is mounted fixedly on the tank 1.
  • the pusher 5, and its limited thrust member 6, will first travel a dead stroke, that is to say that it generates no effect on the distribution of fluid product.
  • the limited thrust member 6 will thus move until the axial support profiles 52 come into contact with the axial support flange 46, which is shown on the figure 3b .
  • the free sliding ends 63 can simultaneously come into contact with the conical surface 75.
  • the dispensing nozzle 4 has not yet moved and the valve 2 is closed. There is no smooth product dispensing yet.
  • the displacement of the pusher 5 and of its limited thrust member 6 into this position takes place at against the leaf springs 64, which presses more strongly on the annular flange 74.
  • the dispensing of fluid product takes place only in the driving phase of the dispensing nozzle 4 until its release, which marks the closing of the valve 2 and the end of the dispensing.
  • the user when he presses on the bearing surface 51 of the pusher 5, does not realize how the various phases described above are proceeding. He presses button 5 naturally and instinctively, so that there is no downtime between the different phases described above.
  • the driving of the dispensing endpiece 4 by the limited thrust member 6 takes place only over part of the total stroke of the pusher 5.
  • the proportion of the stroke corresponding to the driving of the dispensing endpiece 4 can be adjusted by acting on the length of the legs 61 and the inclination of the conical surface 75.
  • the radial projection of the profiles 62 also influences the length of the drive stroke. The brevity of the dispensing therefore depends on the stroke length corresponding to the drive of the dispensing nozzle 4.
  • valve-operated fluid dispenser which by definition provides continuous dispensing of fluid
  • pseudo-pump dispenser in the sense that the dispensing of fluid is automatically completed, as soon as when the pusher is fully pressed.
