Description
- This present invention concerns a device for the dispensing of a fluid product, and more particularly a device of the aerosol type, including a non-metering dispensing valve and an external metering system mounted on the said valve.
- In systems of the aerosol type, it is common to use valves to dispense the product by means of a propellant. These valves can be metering valves, which dispense accurately metered quantities with each operation. These valves are quite complex to manufacture and to assemble, in particular when one requires to guarantee optimal metering accuracy. Likewise, the use of a metering valve considerably complicates the filling of the reservoir with the fluid product and the propellant, which also increases the costs. Moreover, in a metering valve, the metering chamber is generally filled just after dispensing the preceding quantity, so that in the event of an extended period of storage, the latter takes place with the chamber full. Furthermore, non-metering or continuous valves which dispense the product for as long as the valve stem is kept in its dispensing position, which is generally in the pressed position, are not suitable for a certain number of products, such as pharmaceutical products for example. These non-metering valves, which are very simple to manufacture and to assemble, and which allow very easy filling of the reservoir, therefore do not allow quantities of product to be dispensed in a precise manner.
- Documents FR 1 325 336, U.S. Pat. No. 4,915,262 and JP 2000/084444 describe push-button metering devices capable of being fitted to a continuous valve. These push-button devices are complicated, composed of many parts, and therefore costly to manufacture and to assemble.
- This present invention has as its aim to supply a fluid-product dispensing device which does not have the aforementioned disadvantages.
- More particularly, this present invention has as its aim to provide a fluid-product dispensing device which allows the dispensing of accurate and repeatable quantities of the product contained within the reservoir.
- In particular, this present invention has as its aim to supply a fluid-product dispensing device which guarantees both easy and simple filling, and accurate and repeatable dispensing, of the product contained in the reservoir.
- This present invention also has as its aim to provide such a device in which the metering chamber is filled just before expulsion of the metered quantity.
- This present invention also has as its aim to supply such a device which is simple and inexpensive to manufacture, to assemble and to use.
- This present invention therefore has as its subject a fluid-product dispensing device that includes a reservoir containing a fluid product and a propellant, with a non-metering dispensing valve being mounted on the said reservoir, the said valve including a valve stem that is movable between a closed position and an open position, the said valve being designed to dispense fluid product for as long as the valve stem is kept in the open position, with the device also including a dispensing head mounted on the said valve stem and including a dispensing orifice, characterised in that the said head includes a metering system designed to dispense a precise and repeatable metered quantity of fluid product with each operation of the device.
- Advantageously, the said metering system includes a control element to move the said valve stem between its closed and open positions, and a metering element which is movable in relation to the said control element between a shut-off position and a dispensing position.
- Advantageously, the said metering system includes an operating element, to move the said control element and the said metering element.
- Advantageously, the said operating element fits onto the said control element by means of an elastic element, such as a spring whose stiffness is greater than the force necessary to move the valve stem, so that at the start of the operation, the operating element, the control element and the metering element all move together as a static unit.
- Advantageously, when the control element is in abutment, with the valve stem in the open position, product is fed into the said dispensing head, with the metering element, in the shut-off position, preventing any dispensing of this product.
- Advantageously, when the control element is in abutment, with the valve stem in the open position, continuation of the operating element on its operating trajectory gives rise to a deformation of the said elastic element placed between the operating element and the control element, and therefore a movement of the said operating element and of the said metering element in relation to the said control element.
- Advantageously, when the metering element moves in relation to the control element, it first arrives at a metering position, in which it shuts off, in a sealed manner, a passage to the said valve stem, thus determining the volume of the metered quantity, and then at a dispensing position, in which the said metered quantity is dispensed through the said dispensing orifice.
- Advantageously, a control element is hollow and forms, at least partially, a metering chamber and a feed passage between the said metering chamber and the said valve stem, the said metering element including a first gasket forming, together with the said feed passage, an entry valve for the metering chamber, and a second gasket forming, together with the metering chamber, and exit valve from the metering chamber.
- Advantageously, during operation, the said entry valve closes before opening of the said exit valve, and after operation, the said exit valve closes again before opening of the said entry valve.
- Advantageously, the said first gasket is annular and fits onto the walls of the feed passage in the closed position of the entry valve, where the said passage and/or the said metering chamber include walls of larger diameter fitting the said first gasket in the open position of the said entry valve.
- Advantageously, the said second gasket is annular, and fits onto the walls of the said metering chamber in the closed position of the exit valve, the said metering chamber including walls of larger diameter fitting with the said second gasket in the open position of the said exit valve.
- Advantageously, the said operating element is snapped onto the said control element.
- Advantageously, the control element contains a metering chamber, the said metering element simultaneously forming the entry valve and exit valve of the said metering chamber.
- Other characteristics and advantages of this present invention will appear more clearly on reading the following detailed description of one particular embodiment of the latter, with reference to the attached drawings, given by way of non-limited examples, and in which :
-
FIG. 1 is schematic view in cross section of a fluid-product dispensing device according to this present invention, in the rest position, -
FIG. 2 is a view similar to that ofFIG. 1 , at the start of the operation, in the position for loading of the metered quantity, -
FIG. 3 is a view similar to that ofFIGS. 1 and 2 , during operation, in the position for isolation of the metered quantity, -
FIG. 4 is a view similar to that of FIGS. 1 to 3, in the position for expulsion of the metered quantity, and -
FIG. 5 is a view similar to that of FIGS. 1 to 4, with the device returning to the rest position after expulsion of the metered quantity. - The drawings, which represent one advantageous embodiment of this present invention, show a fluid-product dispensing device that includes a
reservoir 10 on which is mounted a continuous valve, also known as anon-metering valve 20, by means of a crimped-oncapsule 15 for example. The operation of a continuous non-metering valve is very simple, since in the rest position represented inFIG. 1 , the valve is closed and the contents of thereservoir 10 are isolated, while when in the dispensing position, with the valve stem pressed fully down, product is dispensed. - In order to achieve accurate metering of the product quantity dispensed with each operation, the device according to the invention specifies a
metering system head 30 which is mounted on the valve stem of thevalve 20. This metering system acts during the operation of the device, and ensures that the same metered quantity is dispensed with each operation, independently of the position of the valve stem of thecontinuous valve 20. In the example represented in the drawings, the metering system includes acontrol element 32 which is designed to move the valve stem of the valve between its closed and open positions. Thecontrol element 32 is preferably hollow and includes within it ametering element 33 which is movable in relation to the saidcontrol element 32 between a shut-off position represented inFIGS. 1 and 2 and a dispensing position represented inFIG. 4 . Anoperating element 34, to which the user applies force during the operation, fits onto both thecontrol element 32 and themetering element 33 to move these during the operation. As can be seen in the figures, an elastic element, such as aspring 35, is preferably placed between theoperating element 34 and thecontrol element 32. The stiffness of thisspring 35 is greater than the force necessary to move the valve stem of thevalve 20, so that at the start of the operation, it is the valve stem of thevalve 20 which is first pressed fully down while thespring 35 does not deform. At the start of the operation, thecontrol element 32, theoperating element 34 and themetering element 33 therefore move together forming a static unit. This movement is shown inFIG. 2 . In the position represented inFIG. 2 , thecontrol element 32 has therefore moved the valve stem of thevalve 20 to its open position. At that instant, product is expelled by the saidvalve stem 20. Thecontrol element 32, which is hollow, forms ametering chamber 50 which is connected firstly to a dispensingorifice 31 and secondly to the output of thevalve stem 20 by means of afeed passage 40. - The
metering element 33, which is movable in relation to thecontrol element 32, is used to shut off the saidfeed passage 40 to allow a metered quantity to be loaded, and to open the output of themetering chamber 50, to allow the expulsion of the product through thedispensing orifice 31. As can be seen inFIG. 2 , when thecontrol element 32 arrives at the end of its travel on thefixing capsule 15, thefeed passage 40 is open into themetering chamber 50, while thismetering chamber 50 is isolated from the dispensingorifice 31. At that instant, the product is therefore fed into themetering chamber 50, filling it. There is no expulsion of product through the dispensingorifice 31, since the passage to this orifice is closed. When the user continues pressure on theoperating element 34, this then deforms thespring 35, which gives rise to the movement of themetering element 33 within thecontrol element 32. As can be seen inFIG. 3 , thefeed passage 40 is then firstly closed in relation to themetering chamber 50, which totally isolates the metered quantity within the metering chamber. This metering position is used to determine the volume of this metered quantity in a very precise and repeatable manner. Finally, continuation of the operating trajectory of theoperating element 34 moves themetering element 33 still further. As represented inFIG. 4 , themetering element 33 then opens the passage between themetering chamber 50 and the dispensingorifice 31, and thus allows the product to be dispensed. After expulsion of the product, when the user releases pressure on theoperating element 34, thespring 35 and the spring of the valve stem 20 return the metering system to its rest position. During this return to the rest position, themetering element 33 first closes the connection between themetering chamber 50 and the dispensingorifice 31 before again opening thefeed passage 40 to allow the loading of a fresh metered quantity. - The preferred embodiment represented in the figures includes a
metering element 33 fitted with afirst gasket 36 forming, together with the saidfeed passage 40, an entry valve for themetering chamber 50, as well as asecond gasket 37 which forms, together with themetering chamber 50, an exit valve from themetering chamber 50. As described above, during the operation, the entry valve closes before opening of the exit valve, and after operation, when the device returns to its rest position, the exit valve closes again before opening of the entry valve. Advantageously, thefirst gasket 36 is annular and fits onto a wall of thefeed passage 40 in the closed position of the entry valve, the saidgasket 36 being placed within themetering chamber 50 when the entry valve is in the open position. In a variant, one could envisage that in the open position, thefirst gasket 36 fits onto a wall part of larger diameter than the saidfeed passage 40. Furthermore, thesecond gasket 37 is also advantageously annular, and fits onto the walls of themetering chamber 50 in the closed position of the exit valve, with the saidmetering chamber 50 having walls of larger diameter which fit onto the saidsecond gasket 37 in the open position of the exit valve. This open position of the exit valve is shown inFIG. 4 , with a very slight difference in the diameter being sufficient to allow the metered product quantity to be expelled, in particular by the presence of a propellant gas. - Advantageously, it is possible to arrange for an atomising profile not shown at the level of the dispensing
orifice 31, in order to favour dispensing in the form of a spray. The operatingelement 34 is shown as being click-fitted or snapped on thecontrol element 32, but it is intended that any other means of attaching these various elements can be envisaged. - The invention has been described with reference to one particular embodiment of the latter, but it is clear that it is not limited to the example represented. In particular, the arrangement of the various elements forming the metering system operating element, elastic element, control element, and metering element can differ, and these various elements can be implemented in a different fashion, on condition that it adequately performs the metering function during the operation of the device. In particular, the position and the shape of the gaskets formed on the
metering element 33 can be implemented in any manner desired. Likewise, the shape of the entry and exit valves of the metering chamber can also be implemented in any manner desired. - One obvious advantage of this present invention is that it allows implementation of a metering system, and therefore the dispensing, in an accurate and repeatable manner, of the product contained in the
reservoir 10, while still using a non-metering valve. Moreover, the filling of the metering chamber occurs advantageously just before expulsion of the metered quantity. The use of a non-metering valve has many advantages, in particular regarding the manufacturing and assembly costs. It also simplifies the filling of the reservoir with the product and the propellant gas, to a very significant degree. Someone skilled in the art will also be able to perform all necessary changes to this present invention as described above, without moving outside the scope of the present invention as described in the appended claims.
