Definitions
- the present invention relates to a fluid product dispensing device having a liquid to pasty consistency contained in a reservoir, said dispensing device dispensing fluid product in the form of a fixed spray.
- the term "fixed spray” means a j and of fluid product in sprayed form which does not move when the device is actuated. Indeed, most of the dispensing devices are actuated by translational movement of a pusher incorporating the nozzle on which one acts using a finger or an actuating device. The fixity of the spray is therefore to be taken with respect to the reservoir.
- Fixed spray dispensing devices which can be a simple or precompression pump or a metering valve or not, can for example find their usefulness in applications related to pharmacy in which the accuracy of j and is important.
- the invention proposes to use conventional dispensing devices with non-fixed spray modified so that their spray is made fixed.
- the subject of the present invention is a device for dispensing a fluid product contained in a reservoir, said device comprising: a pump or a valve of conventional type comprising a fixed body in which an actuating rod is movable between a position of rest and a dispensing position, said rod being hollow so as to form a delivery channel bringing fluid communication into at least part of said fluid product with outlet orifices formed on the rod, characterized in that the device comprises further - a dispensing member fixedly mounted on said body, said dispensing member having a fixed dispensing orifice and communication means for placing said movable outlet orifices in fluid communication with the orifice fixed dispenser at least in the dispensing position, and a push button mounted on the actuating rod so as to close the delivery channel at its upper end.
- the fluid product is expelled from the chamber through the delivery channel incorporated in the movable actuating rod.
- the fluid passes through the actuating rod which allows the use of conventional dispensing devices not producing of fixed spray.
- the actuating rod could be a valve stem of a valve or an actuating rod of a precompression pump or not
- the valve or the pump is of a completely conventional type and therefore of relatively low cost low. Consequently, by simply adapting the dispensing member and the push button on the rod, a fixed spray dispensing device is obtained.
- the communication means comprise an outlet chamber integral with the dispensing member in which a part of the rod comprising at least the outlet orifice means is slidably mounted in leaktight manner, said chamber communicating , at least in the dispensing position, the outlet ports of the rod with the dispensing port.
- the outlet chamber surrounds the rod over a height substantially equal to the stroke height defined between the rest position and the dispensing position of the rod.
- the outlet chamber is provided with two annular sealing lips in leaktight sliding contact with the rod.
- the fluid product discharged through the discharge channel through the outlet port means therefore arrives in a chamber high enough to allow the outlet port means to be at all times in communication with this outlet chamber at least on part of the stroke of the rod going to its dispensing position.
- the outlet orifice means can be at any time in communication with the outlet chamber throughout the stroke of the rod between the rest position and the dispensing position.
- the dispensing device should be fitted with an outlet valve.
- the rod outlet orifice means, in the rest position can be isolated from the dispensing member.
- the rod outlet orifice means are located outside the outlet chamber in the rest position.
- the obstruction of the outlet orifice means in the rest position plays the role of outlet valve means.
- the outlet orifice means are therefore masked.
- This alternative embodiment is particularly suitable in the case where the rod is an actuating rod of a precompression pump, in which a short initial stroke of the rod serves to put the fluid product under pressure.
- Figure 1 is a sectional view of a dispensing device according to a first embodiment of the present invention
- Figure 2 is a sectional view of a dispensing device according to a second embodiment of the present invention, showing the internal structure of the device.
- the present invention applies to any dispensing device having an actuating rod movable between a rest position and a dispensing position.
- a dispensing device of this type mention may be made of simple or precompression pumps and metering valves or not.
- FIG. 1 a dispensing device has been shown designated by the reference numeral 1, the internal structure of which is not not visible. It should be understood that it can be either a pump or a valve.
- the dispensing device 1 is mounted on the neck 2 of a container on which it is fixed by a crimping 14.
- the container can be a pressurized container or not.
- the dispensing device 1 comprises a fixed body 10 in which an actuating rod 11 surmounted by an actuating pusher 13 is movable between a rest position and a depressed dispensing position.
- the actuating rod 11 is hollow and communicates through an internal delivery channel 15 the distribution chamber, in the case of a pump or a metering valve, or the container itself in the case of a non-metering valve, with one or more outlet orifices 12 formed laterally in the actuating rod 11.
- a dispensing member designated as a whole by the reference numeral 3, which is mounted on the dispensing device in a stationary or static manner with respect to the reservoir. This means that the dispensing member does not move when the push-button 13 is depressed.
- the dispensing member 3 communicates the outlet orifice (s) 12 of the actuating rod 11 with a dispensing orifice 30 which allows a projection of the fluid product in the form of jets of fine spray droplets
- the dispensing orifice 30 can be any suitable nozzle with or without swirl chamber In the embodiment shown in FIG.
- the dispensing member covers the dispensing device with a cylindrical sleeve 33 which extends over the crimp 14 until it contacts the base of the neck 2 of the reservoir.
- This outer sleeve 33 incorporates the nozzle 30 and also allows the depression of the pusher 13 inside the sleeve until the upper surface of the pusher 13 is flush with the upper edge of the sleeve 33.
- the dispensing member 3 comprises further an annular flange 36 which extends from the outer sleeve 33 inwards.
- This annular flange 36 incorporates a distribution duct 34 which extends from the nozzle 30 inwards where it opens into an outlet chamber 31 formed by a sealing sleeve 32 which is formed in one piece with the flange annular 36 and the outer sleeve 33.
- the annular flange 36 also incorporates a vent hole 35 which allows air to enter as fluid is distributed in the case of a non-airless pump.
- Snap tabs 37 extend from the underside of the annular flange 36 and are engaged with the dispensing device for securing the dispensing member 3 to the dispensing device 1
- the tabs snap-fit 37 must be strong enough to prevent any relative displacement of the dispensing member 3 relative to the dispensing device 1. The dispensing member 1 is therefore snapped onto the dispensing device 1.
- the push-button 13 acts as a plug to close the open upper end of the actuating rod, which is normally connected to a conventional dispensing head incorporating a nozzle or a nozzle. ensure good sealing and good support, the push-button 13 is force-fitted into the actuating rod; an annular sealing bead can for example improve the sealing.
- the dispensing member 3 and the push button 13 of the invention it is possible to transform virtually any conventional pump or valve into a fixed spray dispenser, the dispensing member 3 making it possible to bring the fluid from the movable actuating rod to the fixed nozzle and the push button for closing the upper end open the delivery channel 15 of the actuating rod 11.
- the outlet chamber 31 formed by the sleeve 32 is crossed by the actuating rod 11 of the dispensing device 1.
- the outlet chamber 32 is made watertight by two annular sealing lips 320, 321 which are in sealed sliding contact with the actuating rod 11.
- the effective volume of the outlet chamber 31 is therefore defined by the annular formed between the sleeve 32 and the actuating rod 11.
- the outlet port (s) 12 of the actuating rod 11 are located inside the outlet chamber 31.
- the hollow actuating rod 11 is in fluid communication with the outlet orifice 30 via the outlet orifice (s) 12, the outlet chamber 31, and the dist duct ribution 34.
- the outlet chamber 31 must have a sufficient height to allow the outlet orifices 12 to be inside the outlet chamber 31 when the rod actuation reaches its dispensing position, that is to say the lowest position. It is essential that the outlet port (s) of the actuating rod 11 are located inside the outlet chamber 31 at least in the dispensing position.
- the fluid is discharged through the actuating rod 11, either from the start of the stroke of the rod towards its dispensing position, or from a certain length of stroke during which no fluid is distributed.
- a precompression pump in which the product is dispensed only after a certain distance of travel of the actuating rod which makes it possible to overcome a precompression spring.
- the interior of the dispensing device must be in fluid communication with the dispensing orifice 30. Since the orifice (s) of the actuating rod 11 are permanently located inside the outlet chamber 31, it is ensured that all of the fluid is distributed through the dispensing orifice 30.
- the dispensing member 3 according to the invention makes it possible, thanks to its outlet chamber 31, to erase the effects of the displacement of the actuating rod 11 on the jet of fluid product sprayed at the outlet.
- the distribution chamber 31 therefore makes it possible to restore the fixity of the spray of sprayed product.
- the fixity of the jet is particularly appreciable in the case of the use of dispensing devices in which the precision of the jet is important, as is the case in the pharmaceutical field.
- the dispensing member of the invention can be adapted to practically any dispensing device having an actuating rod.
- FIG. 2 shows the internal structure of the dispensing device, which in this case is a precompression pump.
- a return spring 17 pushes the actuating rod 11 towards its rest position which is that shown in FIG. 2
- the precompression necessary to obtain a good quality of the jet of sprayed product is ensured by a second spring 16 called precompression.
- a detailed explanation of the operation of a precompression pump will not be made here, and reference may for example be made to the document FR - 2 403 465 for further explanations.
- the precompression pump has been slightly modified in that it no longer comprises an outlet valve, the function of which is now ensured by the dispensing member 3.
- the actuating rod 11 opens directly into the pump chamber.
- the outlet orifices 12 of the actuating rod 11 are not located in the outlet chamber 31 of 1 dispensing member in the rest position.
- the outlet orifices 12 are located, in the rest position, in an insulated chamber 315 closed by two annular sealing lips 320 and 325. Consequently, the outlet orifices 12 of the actuating rod 11, in the rest position, are isolated from the outside by the double row of annular lips 320 and 325.
- the insulated chamber 315 fulfills the function of outlet valve chamber by isolating the pump chamber from 1 exterior
- the outlet orifices 12 are therefore not positioned in the outlet chamber 31 of 1 dispensing member in the rest position.
- the outlet orifices 12 will not be in communication with the outlet chamber 31 until after the actuating rod 11 has made a certain travel distance.
- the actuating rod 11 must reach with these outlet orifices 12 the outlet chamber 31 which is also delimited by a double row of annular lips 320 and 321.
- the annular lip 320 delimits the separation between the valve chamber 315 and the outlet chamber 31.
- the dispensing member of the invention therefore fulfills a double function: that of an outlet valve for a precompression pump and that of the fixity of the jet of sprayed fluid product.
- the push-button 13 it also fulfills here the function of shutter of the delivery channel 15.
