Definitions
- the invention relates to a flow restrictor for a pressurized product dispenser, in particular for an aerosol generator of the type equipped with a diffuser and a valve equipped with a stem.
- Pressure product dispensers are commonly used in many fields. To distribute their contents, they are equipped with valves equipped with a stem. Depending on requirements, these may be single-lane valves or two-way valves. Two-way valves are used when two products must be kept separately until they are applied simultaneously. For this, the products are stored in two different tanks, usually two pockets side by side or one in the other, or one in a pocket and the other in the housing of the aerosol. The two-way valves can also be used to dispense the product contained in the distributor by a first route and the propellant through the other way, the product possibly being contained in a bag protected from the propellant gas. To operate the valve, a diffuser is placed at the top of the stem.
- the two products come into contact only at the outlet of the stem, or even at the outlet of the diffuser.
- To introduce the product or products in the pressure product dispensers it is common to enter their tanks (bags or housings) respectively via the valve, so via the pathways through the stem. This operation is all the easier and faster as the products are not very viscous and the channels have a large cross section.
- the entry of the product is facilitated, its exit is also facilitated.
- two-way valves it may also be necessary for the two products not to come out with the same flow rate.
- the two products have different viscosities, it may be necessary to adapt the cross section of the channels to obtain the desired flow rate for each of the products.
- the adaptation of the cross section of the channels to guarantee the desired flow of the product or of each of the two products is done in the stem thanks to the choice of the size and the number of the orifices giving access to the tracks of the stem and in the diffuser via the outlet orifice of the nozzle.
- each stem and nozzle must be adapted case by case, which requires different molds for their manufacture and large stocks.
- the choice of the size and the number of the orifices in the stems can limit the speed of filling when the container is filled via the valve, therefore through the stem.
- the objective of the invention is to allow to adjust the flow rate of a valve, whether one-way or two-way, to the needs related to the products to be applied while maintaining a stem with the widest possible routes .
- the reducer will be designed to allow the other standard components to be retained as well.
- the flow restrictor is constituted by a separate part of the stem and preferably the diffuser, and which comprises
- first outlets which, when the gearbox is mounted on the stem of a valve, are able to be sealingly connected to the first channel of the stem of the valve, forming an extension of the first channel
- the outer face of the gearbox preferably having a contour substantially identical to that of the portion of the stem which projects from the valve and which is intended to be covered by the gear.
- the flow restrictor may further comprise
- one or more second outlet orifices which, when the gearbox is mounted on the stem of a two-way valve, are capable of being sealed to the second path of the stem of the two-way valve by forming an extension the second way
- sealing means which, when the gearbox is mounted on the stem of a two-way valve, are able to maintain the separation of the two tracks at the junction between the gearbox and the stem on which it is mounted and between this junction and the outlets.
- the reducer extends the one or two tracks that remain isolated from each other to the outlets. Simply adjust the number and / or section of the outlets to adjust the flow of products in each channel. It is thus possible to store stems with large section channels and standard diffusers. Only the reducer, simple element to manufacture, is adapted to the case by case.
- the reducer can be used for single-track stems as well as two-way concentric or two-way parallel stems. Whether it is a single-path stem or a concentric two-way stem, the stem usually has a first tubular wall defining the first path.
- the reducer preferably comprises:
- a cylindrical first-way wall defining a first-way cylindrical space forming at least a portion of the recess and having a first end facing the opening of the recess and a second end opposite the opening of the recess, the cylindrical wall of the first channel being adapted, when the reducer is mounted on the stem of a valve, to surround at least partly the first tubular wall of the stem; a top closure wall in the extension of the second end of the cylindrical first-way wall, said top closure wall closing the cylindrical first-way space;
- the first outlet orifice or openings being made in the top closure wall in an area of the aperture closure wall which, when the reducer is mounted on the stem of a valve, is in contact with the first channel of the stem.
- the flow restrictor comprises a cylindrical top wall defining an upper cylindrical space whose cross section is smaller than the cross section of the cylindrical first-track space, and
- the cylindrical space of the first channel and the summit cylindrical space forming at least part of the recess adapted to be threaded onto a stem;
- the first outlet orifice or openings being made in the second top closure wall in an area of the second top closure wall which, when the reducer is mounted on the stem of a valve, is in contact with the first channel; stem.
- the flow restrictor further comprises
- second-way cylindrical wall defining a second-way cylindrical space forming at least a portion of the recess and having a first end facing the opening of the recess and a second end opposite the opening, the cylindrical wall;
- second channel being adapted, when the reducer is mounted on the stem of a two-way valve, to surround at least partially the second tubular wall of the stem;
- the second outlet orifice (s) being (are) formed in the intermediate closure wall in a zone of the intermediate closure wall capable of being in contact with the second path of the stem.
- Such a flow restrictor allows a separation of the products until its output. If the separation is to continue to the inside of the diffuser, or even to the exit of the diffuser, the top cylindrical wall and the separation of the top closure wall will be provided in a first and a second top closure wall as indicated previously. If on the contrary, a separation of the products beyond the stem is not necessary, it is possible to give up the cylindrical top wall.
- provision may be made to produce one or more channels in the first channel cylindrical wall, which channels extend up to the top closure wall or up to the first top closure wall. and each channel opens onto one or more of the second outlet ports.
- first channel sealing tip on the top closure wall or at the first end of the top cylindrical wall, the first channel sealing end being suitable when the reducer is mounted on the stem of a valve two-way, to be introduced into the first path of a valve stem by sealing at the junction between the first path of the valve stem and the flow restrictor, and / or
- a second-channel sealing tip placed at the first end of the first-channel cylindrical wall, the second-channel sealing tip being suitable, when the reducing gear is mounted on the stem of a two-way valve, to be introduced into the second path of the stem by sealing at the junction between the second path of the stem and the flow restrictor.
- the outer contour of the first-channel cylindrical wall is adapted to cooperate with a diffuser, preferably with a diffuser adapted to cooperate with a stem for which the flow restrictor is intended.
- the outer contour of the cylindrical top wall may be adapted to cooperate with a diffuser for a single-way or two-way valve, in particular with a diffuser adapted to cooperate with a stem for which the flow restrictor is intended.
- the outer contour of the gearbox at the level of the cylindrical wall of the first lane and, if appropriate, of the cylindrical top wall is preferably substantially identical to the contour of the stem on which it is mounted so that it co-operates with the diffuser as the stem would have done. It is therefore possible to use the same diffusers for bare stems or stems equipped with a reducer. If it is not necessary to use the same broadcasters and specific broadcasters can be made, we can give up this identity form.
- the flow reducer can be sold separately. It can also be sold associated with the valve and / or the diffuser for which it is intended, especially in the form of a set. It is also conceivable that the reducer is sold premounted on the diffuser for which it is intended.

- the invention relates to a flow restrictor (10) for a stem (20) of a one or two-way valve (30) used with a housing (40) in pressure vessels. Such stems (20) are sometimes called valve stems.
- the flow restrictor is intended to be placed between the free end of the stem (20) protruding out of the valve and the diffuser (50), itself usually placed directly on this projecting end.
- the stems (20) may be of the concentric-channel type as in the example presented here (see in particular FIG. 8), or may be of the parallel-channel type.
- a two-way valve stem can be used in a two-way valve (30) with parallel pockets such as that shown by way of example in Figure 1 or concentric pockets (bag-in-bag).
- the stem and the flow restrictor of the invention usually have a certain symmetry of rotation around a main axis (A) passing through the stem and the pressure reducer.
- This symmetry of rotation is not absolute, some parts of the reducer moving away.
- the adjectives "axial” or “radial” refer to this main axis (A) and respectively define an element parallel to the axis or perpendicular to this axis.
- spatial references such as “high” and “low” or “higher” and “lower” refer to the flow restrictor and stem as shown in Figure 1 for example.
- a stem for a one-way valve generally comprises a first tubular wall forming a cylindrical channel open upwards and forming part of the single lane. This single path, when the valve is open, communicates with the inside of the housing or with a reservoir placed inside the housing, such as a flexible bag.
- this first tubular wall (21) is partially surrounded by a second tubular wall (22) forming an annular channel open upwards and forming part of the second channel.
- the second tubular wall (22) does not generally extend as high as the first central tubular wall (21).
- Each path of the stem when the valve is open, communicates with its respective reservoir, generally a flexible pouch or the inside of the case, in known manner via the valve.
- the product to be dispensed is contained directly in the housing with the propellant, the product exiting through the first channel and the propellant by the second channel. To simplify the rest of the description, it will generally refer to pockets without this being a limitation, these pockets can be replaced by any other type of tank capable of performing the same function.
- the flow restrictor (10) of the invention is slipped on the projecting end of the stem and can maintain the separation of the channels when it is intended for a two-way valve.
- the flow restrictor (10) consists of three main parts: a first cylindrical wall (1 1), corresponding to the cylindrical wall of the second channel, a second cylindrical wall (12) corresponding to the cylindrical wall of first lane, and a third cylindrical wall (13), corresponding to the cylindrical top wall, each defining a cylindrical interior space.
- the first end (lower end) of the first cylindrical wall (1 1) is open and constitutes the lower end of the flow restrictor (10).
- the second end (upper end) of the first cylindrical wall (1 1) and the first end (lower end) of the second cylindrical wall (12) are connected together by a first radial wall (1 1 1), corresponding to the wall intermediate closure.
- the second end (upper end) of the second cylindrical wall (12) and the first end (lower end) of the third cylindrical wall (13) are connected together by a second radial wall (121) corresponding to the first closure wall summit.
- the third cylindrical wall (13) is closed at its second end (upper end) by a third radial wall (131) corresponding to the second top closure wall.
- the cylindrical walls and the radial walls contribute to closing the interior spaces defined by the three cylindrical walls and constitute closure walls.
- the cylindrical walls and the radial walls together define a recess corresponding to the three cylindrical spaces.
- the recess is open at the free end of the first cylindrical wall (first end opposite the first closure wall (January 1)). It will be seen that this recess is adapted to be threaded through the opening of the recess on a two-way stem, without the stem necessarily entering the bottom of the recess. In particular, the stem is not intended to penetrate into the summit cylindrical space.
- the three main walls (1 1, 12, 13) of the flow restrictor (10) are not necessarily absolutely cylindrical. They may be slightly frustoconical, generally not noticeable, to facilitate demolding.
- the inside diameter of the first cylindrical wall (1 1) of the flow restrictor is substantially equal to or slightly less than the outside diameter of the second tubular wall (22) of the stem.
- the inside diameter of the second cylindrical wall (12) is substantially equal to or slightly smaller than the outside diameter of the first tubular wall (21) of the stem. This is clearly visible in Figures 6 and 7.
- the outside diameter of the second cylindrical wall (12) of the flow restrictor is substantially equal to the outside diameter of the second tubular wall (22) of the stem
- the outside diameter of the third cylindrical wall (13) is substantially equal. to the outer diameter of the first tubular wall (21) of the stem. This is also visible in FIGS. 6 and 7.
- the outer contour of the gearbox, at the level of the second and third cylindrical walls, is substantially identical to the outer contour of the upper part of the stem intended to penetrate into the diffuser ( 50).
- the first tubular wall (21) of the stem penetrates into the second cylindrical wall (12) of the reducer and the second tubular wall (22) of the stem penetrates into the first cylindrical wall (1 1) of the reducer.
- the inside diameters of the first and second cylindrical walls (1 1, 12) are thus chosen to ensure permanent contact between the inner face of this cylindrical wall (1 1, 12) and the outer face of the tubular wall (21 , 22) corresponding to the stem (see in particular Figures 6 and 7).
- the assembly requires a slight force to overcome the friction of the walls on each other, which ensures that the restrictor remains on the stem without risk of it going away.
- the internal diameter of the cylindrical walls (1 1, 12) must not be too small so that the assembly does not require too much force that could damage the stem or the restrictor.
- the height of the outer face of the third cylindrical wall (13) is preferably substantially equal to the difference in height between the top of the first tubular wall (21) and the top of the second tubular wall (22) of the stem.
- the inner height of the first cylindrical wall (1 1) and that of the second cylindrical wall (12) are chosen from such that the two tubular walls (21, 22) of the stem are each in contact with at least a portion of the inner face of the corresponding cylindrical wall (22/1 1, 21/12) when the flow restrictor is mounted on a stem while ensuring on the one hand the continuity of the two channels and on the other hand their tight separation. It is not necessary that the first cylindrical wall (1 1) of the flow restrictor is as high as the projecting portion of the second tubular wall (22) of the stem.
- the third cylindrical wall (13) can extend downwards, inside the second cylindrical wall (12), by a first-way sealing tip (132). ) whose outer diameter is substantially equal to the inner diameter of the first tubular wall (21) of the stem.
- the second cylindrical wall (12) of the reducer can extend downwards, inside the first cylindrical wall (1 1), by a second-channel sealing tip (122) whose outer diameter is substantially equal to the inside diameter of the second tubular wall (22) of the stem. Due to the tight fitting of the first cylindrical wall (1 1) on the second tubular wall (22) of the stem on the one hand, and the second cylindrical wall (12) on the first tubular wall (21) of the stem of on the other hand, it would be possible to give up the second channel seal (122).
- first and second cylindrical wall (1 1, 12) at their respective lower ends to allow a self-centering effect of the reducer with respect to the stem.
- a second channel sealing tip (122) is provided, it is sufficient to chamfer the inner face thereof, without the chamfer necessarily reaching the inner face of the second cylindrical wall (12).
- a central channel (133) of substantially constant diameter passes through the third cylindrical wall (13) from its lower end, or the lower end of the sealing cap (132) when there is one, to the third radial wall (131) closing the third cylindrical wall (13).
- a central outlet (134) is formed in the third radial wall to contact the central channel (133) and the exterior of the reducer. This outlet (124) corresponds to one of the first outlets. Rather than a single orifice, it would be possible to make several orifices in the third radial wall (131). Similarly, one or more side channels (123), here two, can be made in the thickness of the second cylindrical wall (12).
- Each side channel (123) terminates in one or more outlets (124) formed in the second radial wall (121) closing the second cylindrical wall. These outlets (124) correspond to the second outlets.
- the side channels (123) can be made entirely in the mass of the cylindrical wall (12), or only be partially included in this wall, as is the case in the example presented here. This is clearly visible in FIGS. 3 and 5. In this case, the outer face of the first tubular wall (21) of the stem closes the lateral wall of the tubular channels (123) as shown in FIG. 6 and FIG.
- the flow restrictor (10) is preferably made of a plastic material, for example a flexible polyolefin to facilitate tight fitting and participate in the sealing of the tip (10) on the stem (20).
- the product contained in the first tank leaves the valve by the first channel, which ends in the central channel located in the first tubular wall (21).
- stem The product leaving the stem through this first channel enters the central channel (133) of the third cylindrical wall of the flow restrictor and exits through the outlet port (134) at the top of the restrictor.
- the central channel (133) is therefore an extension of the first channel.
- the product leaving the stem by this second channel enters the two lateral channels (123) and exits through the outlet orifices (124) located on the second radial wall (121) at the junction between the second and the third cylindrical wall (12). , 13).
- the side channels (123) therefore constitute an extension of the second channel. Leaving the orifices (124, 134), the products enter the diffuser as they would have if they had left the stem directly.
- the first channel sealing tip (132) ensures separation of the two products.
- the sealing tip (122) of the second channel contributes to the sealing of the second channel relative to the outside.
- the cross-section of the outlets (124, 134) and / or the number of lateral channels (123) are chosen according to the needs, namely the ratio between the two products to be dispensed taking into account the viscosity of each. It is therefore possible to have several different flow restrictors for the same set of stem and diffuser. A stem with two tracks of large cross-sections is preserved, allowing a rapid filling of pockets, while being able to adapt the output flow rate with the reducer of the invention. Because of its outer contour with the same dimensions as those of the stem, it is not necessary to modify the diffusers that can be transferred to the gearbox as they would on a stem.
- the gearbox can be delivered alone, mounted in a diffuser or placed temporarily on a two-way valve.
- the second radial wall (121) closing the top of the second cylindrical wall (12) extends over the entire cross section of the channel defined by the cylindrical wall (12), the central outlet (134) being made in the center of this radial wall (121) so as to be in front of the first path of the stem defined by the first tubular wall (21). It is even conceivable to give up the first channel sealing tip (131).
- the system can be adapted to parallel rather than concentric channel stems.
- the flow restrictor is provided with two non-concentric parallel channels each with one or more outlet orifices whose cross section is adjusted on a case by case basis.
- the flow restrictor of the invention has almost no effect on the pressure and does not fulfill the function of a pressure reducer.
- the reducing agent of the invention can be used for any type of aerosol, for the application of pasty products, for foams, gels or liquids. It can be applied to pocket valves whose pockets can be welded or snapped onto the valve body.
