Definitions

• metering valves in which each time the valve is actuated, a precise dose of fluid product is dispensed, are well known in the state of the art, and are generally assembled on a reservoir containing the fluid product and a propellant gas used to carry out the expulsion of the dose.
• the filling of the reservoir of a fluid product dispensing device comprising a valve, in particular a metering valve, is generally done by means of a filling device which sends a pressurized flow of fluid product through the valve of the valve.
• a filling device which sends a pressurized flow of fluid product through the valve of the valve.
• the valve valve is inserted into a filling head which actuates the valve by moving the valve to its dispensing position and which then injects the fluid product through the outlet port of the valve.
• the fluid passes through the valve and enters the metering chamber and thence into the reservoir by deforming the chamber seal.
• the filling pressure is between 5 and 10 bars, which is sufficient to deform the chamber seal, which typically deforms from a pressure of 2 to 3 bars.

Inside said valve body 110, a valve 120 slides between a rest position, which is that shown in Figure 1, and a dispensing position, in which the valve 120 is pressed axially downwards inside the valve body 110.

These openings 111 allow the metering chamber 170 to be filled before each actuation, when in the inverted position of use (with the valve placed under the reservoir), the valve 120 is in its rest position.
• the metering chamber 170 is defined between two annular seals, a top seal or valve seal 171 and a bottom seal or chamber seal 172, in a well-known manner. This metering chamber 170 is filled before each actuation with a dose of fluid product from the reservoir, when the user returns the device to the inverted position.
• the volume of the metering chamber 170 is defined by means of a chamber insert 175, of substantially cylindrical shape, with a cylindrical wall having a greater or lesser radial thickness depending on the desired volume. This volume can advantageously vary between 25 and 75 pl.
• the chamber seal 172 advantageously comprises a radial sealing lip 173 to improve the dynamic seal with the valve 120 during its movement during actuation of the valve.
• This deformable lip 173 extends radially inwards and axially downwards. This implementation makes it possible to guarantee a perfect seal when the valve 120 moves in one direction then in the other direction during an actuation.
• this radial sealing lip allows easy filling of the reservoir through the valve without the risk of damaging the bottom seal 172, as will be described below.
• Figures 2 to 7 describe a filling head of a filling device according to an advantageous embodiment.
• This filling head comprises the following elements: a control member 10, an upper plate 20, a support ring 30, an ejector cylinder 40, a body 50, at least one ejector 60 and a receiving plate 70.
• First fixing means 1 are provided for fixing the control member 10 to the motor (not shown) of the filling device, second fixing means 2 are provided for fixing the upper plate 20 to the body 50, and third means for fixing 3 are provided for fixing the receiving plate 70 to the body 50.

• a first seal 4 is provided on the control member 10, to cooperate with a part of the body 50 when the control member 10 moves relative to the body 50.

During this axial displacement, the first seal 4 cooperates in a sealed manner with said hollow axial sleeve 54 to maintain said reception space 55 sealed. In addition, when the control member 10 moves towards its filling position, the first spring 7 compresses, to at the end of filling return the control member 10 to its rest position.
• This filling head is a so-called blank press head, that is to say that the pressure which it exerts on the valve is applied on the one hand to the valve 120 and on the other hand to the radially external part of the fixing element 130, that is to say the part which cooperates with the reservoir 200 via the neck seal 140.
