Definitions

• the invention relates to a valve according to the preamble of the main claim.
• valves allow two vials of fluid to be withdrawn under pressure, which must be separated before use so that they do not react together before use. This is the case, for example, with hair dyes.
• Valves are known from, for example, EP 1 281 635 A1.
• a first liquid is contained in a flexible pouch which itself is located in a rigid bottle containing on the one hand the propellant and on the other hand the second component of the product, for example a gel.
• the valve consists of two channels, one of which can be brought into contact with the flexible bag and the other with the interior of the container when the valve is actuated.
• the fluid of the bag is not in contact with the fluid contained in the bottle with the gas.
• the propellant propels the second fluid through the second passage.
• the gas presses on the walls of the pocket thus forcing its contents out through the first passage.
• the two components are only encountered at the outlet of the valve, for example in a diffuser. This solution has the major disadvantage that the second component is mixed with the propellant gas. In addition, the gas is necessarily expelled with this second component.
• Document WO 2005/087616 A1 discloses a system of parallel double pockets each provided with a valve. Both pockets are contained in a rigid container under pressure. Both components are both isolated from the gas and each exit through a valve. The propellant can not escape from the container.
• This solution has the disadvantage of requiring two valves.
• US 3,674,180 A discloses a valve with two parallel inlets on each of which is fixed a flexible bag. The two pockets are therefore parallel.
• the disadvantage of parallel pockets lies in the fact that the occupation of the interior of the bottle is not optimal.
• the pockets are not arranged in the axis of the valve, it is difficult to wind them to allow their introduction into the container before filling.
• the volume of the two pockets is necessarily similar, it is not possible, unless further increase the dead volume in the container, to have a significantly larger pocket than the other. Finally, it is not possible to fill the pockets from the valve, because the two parallel inputs end up in a common channel. It is therefore necessary to fill each pocket at the bottom before sealing it and to close the pressure vessel.
• the two pockets are concentric.
• the inner bag is fixed on the valve and the outer bag is fixed on the bottle itself.
• the outer bag is first attached to the bottle and then the inner bag is introduced into the bottle while being held in the upper position by hooks which bear against the neck of the bottle while the pockets are filled.
• the valve is snapped onto the neck of the inner pocket always held in high position by the hooks.
• the valve is pressed into the bottle by carrying with it the hooks inside the bottle. In both cases, it is not possible to manufacture in a first step the valve with the two bags which can then be introduced by the cosmetic manufacturer into the bottle before filling.
• DE 2 160 268 A1 discloses a hermetically sealed bottle containing two concentric pockets. In use, this bottle is introduced into a bottle equipped with a sprayer. The base of the sprayer is provided with two parallel prods which perforate the bottle in two distinct places so that the first goad enters the inner bag and the second into the outer bag. Again, it is not possible to manufacture in a first step a valve with its two pockets.
• the object of the invention is therefore to develop the valve according to the preamble which allows to separate the two fluids and the gas while having only one valve.
• the valve must be able to be manufactured in a first step with its two pockets so that it can be introduced later into a rigid container before filling, preferably by the portion of the valve protruding from the container.
• Another objective is to allow if necessary to let the gas escape from the container.
• Another objective is to allow the addition of a third component in the propellant.
• This object is achieved according to the invention because the first pocket is placed inside the second pocket. In this way, the dead space in the bottle is reduced and the filling rate is thus increased.
• the two pockets being in the winding axis, it is facilitated and the pockets are not likely to tear.
• the volume of each pocket can be chosen freely and it is thus possible to vary at will the ratio between the two volumes.
• first passage with first closure means which, depending on whether they are open or closed, bring the inside or the first pocket into contact with the outside of the valve, and provide the second passage with seconds. sealing means which, depending on whether they are open or closed, bring the inside of the second bag into contact with or isolate the inside from the outside of the valve.
• the first passage and the second passage are constituted by two concentric channels, one of which can be brought into contact with the first flexible bag and the other with the second flexible bag when the means shutter are open. It is a simple way to access the contents of the two pockets, one of which is placed inside the other.
• the propulsion means are constituted by means for exerting pressure on the second flexible bag.
• these means for exerting pressure on the second flexible bag are constituted by a pressurized gas contained in a rigid container in which are placed the two pockets.
• a third passage provided with third closure means which, depending on whether they are open or closed contact or isolate the space outside the second pocket, but inside the rigid container when the valve is mounted on such a container, with the outside of the valve, the third passage may lead into the first or the second downstream passage, with respect to the direction of circulation of the fluids during sampling, means for sealing said first or second passage. It is also possible to add a third fluid to the propellant which, while being separated from the two other fluids, can enter into the composition of the final product leaving the valve.
• the closure means are each constituted by a hole made in a movable wall between a position where they open on one side at least on a second wall so that they form blind holes and a position where they open on one side on spaces in contact with the inside of the pockets and the other on spaces in contact with the outside of the valve.
• the valve comprises a valve body that can be secured to a cup to be fixed on a rigid container, and a stem placed in the valve body and provided with means for moving it between a first position in which the means of shutter are closed and a second position in which the shutter means are open.
• the means for moving the stem between the two positions preferably consist firstly of a spring and secondly of means on which a force opposing the action of the spring can be exerted. These latter means will be constituted for example by a diffuser placed on the valve.
• a valve according to the invention consists essentially of a stem, a valve body, a first and a second seal.
• the stem is provided with a first cylindrical wall forming a central hole closed at its lower end, said first cylindrical wall being provided near the bottom of the central hole of a first radial hole bringing into contact the interior of the central hole with the outer of the stem, and a second cylindrical wall concentric with the first and located outside thereof so as to form an annular channel between the two cylindrical walls, said channel being open in its upper part and closed in its lower part so as not to cross the first radial hole, a second radial hole passing through the second wall so as to bring the inside of the annular channel into contact with the outside of the stem.
• the valve body is provided with a first main part provided with an axial channel in which the stem rests on a spring retained in the axial channel by retaining means, this first main part being able to be provided with a lower lug on which can be placed a tube, the first pocket can be fixed on the outer face of this first main part, and a second main part in the form of concentric collar to the first main part partially covering it so that to form an annular channel between the two main parts, this annular channel having in its bottom, at the level of the junction between the two main parts, orifices.
