- the step of closing is carried out during the assembly of the deformable chamber 45 and the reservoir 3, more precisely by plugging the opening 8 by the head 2 for example by snap-fastening or screwing.
- the filling needle injects of the product in the deformable chamber, preferably during this operation the needle is tightly connected to the supply orifice.
- the method according to the invention can also comprise an additional step of evacuating the deformable chamber 45 (in which a depression is created relative to the outside) a closing step to bring additional product into the deformable chamber 45 from the reservoir 3.
- the outlet 6 of the head 2 can be blocked by a preferably flexible element placed on the valve module or in the outlet orifice and compressed by a cover (not shown) covering the head 2 .
- the deformable movable wall 13 can be replaced by a movable wall such as a rigid piston connected to an actuation button arranged to move this piston so as to vary the volume of the chamber 45 .
- the head 2 comprises a bearing surface 46 of the wall 13.
- the wall 13 comprises a bellows 48 in the form of a helix. This facilitates demolding of the wall 13 during its manufacture.
- the distribution valve 5 is integrated inside a module 47 initially separated from the rest of the head 2,
- the device 102 comprises a channel 220 which emerges from the plug 22 (which forms a bottom wall) in the direction of the reservoir 3.
- This channel 220 has two ends, including:
- the end 221 is equipped with the filling valve 41 (as illustrated in FIG. 11) which is also the intake valve 4, or the other end of the channel 220 is equipped with the filling valve 41 (as illustrated in Figure 10) which is also the intake valve 4.
- the chamber 45 comprises the channel 221 for the filling step (FIG. 11), or
- the reservoir 3 contains (after assembly) the channel 221 for the filling step ( Figure 10).
- the filling step comprises at least partial filling (for example a drop) of product 16 or of a priming product, preferably within the channel 221, so that the product 16 or priming product is in contact of the filling valve 41 (which is also the intake valve 4), at least at the level of the valve seat 41/4, on the side of the reservoir 3 (in the case of FIG. 10 or 11) and / or on the side of the deformable chamber 45 (in the case of FIG. 10 or 11, this requiring a displacement or an opening of the valve 41/4 typically by the rod 50).
- the filling valve 41 which is also the intake valve 4
- the priming product is typically a gel or an oil a liquid (different from product 16 with which the reservoir 3 is filled), such as a carbomer or synthetic hydrophilic polymer of acrylic acid, and / or
- the filling comprises the deposition of priming product as previously described, and can optionally further comprise filling the reservoir 3 with the product 16 (air or another gas which may be present between the priming product in contact of valve 4/41 and product 16 in tank 3).
- the filling step is an at least partial filling step with priming product, so that the priming product is in contact with the filling valve 41 (on the side of the reservoir 3 and / or on the side of the deformable chamber 45), and so that the priming product comprises a gel or a liquid (preferably in the channel 221) between the mobile membrane of the supply valve 4 (which is also the valve of filling 41 in this example) and the valve supply seat 4 (which is also the seat of the filling valve 41 in this case) while the chamber 45 is at least partially filled with gas or with gas.
- the manufacturing method further comprises:
- a step of assembling the deformable chamber 45 to a ring 43 (the bottom wall 22 (or plug 22) being assembled to the chamber 45 before or after the ring 43) passing the deformable chamber 45 through the interior of the ring 43 (more precisely through an orifice 42 in the ring 43), so that the ring 43 surrounds the chamber 45 while leaving an insertion orifice 461 accessible, then
- This insertion is carried out by inserting the valve 5 alone and / or of the module 47 into the orifice 461.
- the module 47 is preferably fixed (preferably by ultrasound) at the head 2 on a weld zone 49 surrounding the orifice 461.
- the ring 43 can be circular or square or the like.
- the manufacturing process comprises a step of assembling the deformable chamber 45 on the reservoir 3 by the ring 43 so that the ring 43 is fixed on the reservoir 3 while exerting a force for holding the chamber 45 and / or the wall 22 on the reservoir 3.
- the ring 43 maintains the bottom wall 22 and / or the chamber 45 in position in the ring 43.
- the ring 43 is screwed or clipped onto the reservoir 3.
- the filling valve 41 (and / or an additional filling valve) is arranged on the head 2 (for example on the wall 46) and / or on the chamber 45, so that the interior of the deformable chamber 45 is separated from the exterior by the filling valve 41 (and / or respectively by the additional filling valve).
