Definitions

• Fluid dispenser and dispenser comprising such a dispensing member
• the present invention relates to a fluid dispenser member, for example of the pump or valve type, intended to be associated with a fluid reservoir to thereby form a fluid dispenser. Moreover, the present invention also relates to such a fluid dispenser.
• This type of distributor and distributor has a preferred application, but not exclusive, in the fields of perfumery, cosmetics or pharmacy.
• the dispensing member comprises a body through which the dispensing member is fixedly mounted on a dispenser mounting part, which may be the reservoir itself or an intermediate element mounted on the reservoir and receiving the distribution organ.
• a dispenser mounting part which may be the reservoir itself or an intermediate element mounted on the reservoir and receiving the distribution organ.
• the body must always be mounted on any mounting piece. In general, this body serves as a support for other constituent elements of the dispensing member.
• the body In the case of a pump, the body generally serves as a support for the inlet valve and also defines, in cooperation with a piston, a pump chamber of variable volume.
• This pump or distribution chamber communicates with the reservoir via the inlet valve and communicates with the outside advantageously through an outlet valve.
• the assembly of the dispensing member on the mounting piece serves only to hold the dispensing member firmly and in a sealed manner in order to constitute a solid and impervious dispenser.
• the mounting of the dispensing member on the mounting piece does not affect the assembly of the various constituent elements of the dispenser member.
• the body defines a housing for receiving another constituent element of the dispensing member
• the fixing and or sealing of this constituent element in the housing of the body is not at all dependent on the mounting of the dispensing member on the mounting piece.
• the present invention aims to use this assembly of the dispenser member on the mounting member to influence the assembly or cooperation of the various constituent elements of the dispenser member.
• the mounting of the dispensing member on the mounting piece must be able to improve the attachment and / or sealing of a constituent element of the dispensing member on its body.
• the present invention proposes a fluid product dispensing member intended to be associated with a fluid reservoir to form a fluid dispenser, said member comprising a body through which the dispensing member is fixedly mounted on a mounting piece, the body defining a housing for receiving another constituent element of the dispensing member, characterized in that the housing comprises a movable portion movable from an initial configuration, wherein the housing is open, to a final configuration, wherein the housing is closed on the component, during assembly of the dispenser member in the mounting part. Therefore, the dispensing member, before its mounting on the mounting piece, is not in its final assembly configuration that will only be reached when it is permanently mounted on the mounting piece. In other words, the mounting piece is used to complete or complete the assembly of the dispensing member.
• the mounting piece thus serves as a constraint or biasing means which make it possible to bring the dispensing member into its final assembly configuration. Instead of closing a housing, it is quite possible to imagine that the mounting part urges a part of the body or a part of a constituent element to engage with another constituent element of the dispenser member .
• the mounting piece thus makes it possible to bring the dispensing member into a final assembly configuration from a pre-assembled or non-definitive pre-assembly configuration.
• the movable portion of the housing may comprise an outer peripheral flange which is deformable radially inwardly against said component to firmly lock it in the housing.
• the flange is continuous on its periphery.
• the collar is split on its periphery. The flange is thus inserted, engaged or fitted inside the mounting piece which tightly surrounds the flange and deforms or moves radially inwardly. The mounting piece thus acts as a hoop that tightly surrounds and constrains the flange inwardly.
• said constituent element forms with the body a fluid dispensing chamber.
• said constituent element forms an elastically deformable membrane provided with an anchor heel sealingly engaged in the housing, moving the movable part compressing the heel in its housing.
• the heel of the deformable membrane is pre-mounted in the housing and held inside thereof sufficiently to be able to handle, store and report the organ distribution on its mounting piece. Closing the housing by moving the movable portion ensures not only a perfect attachment of the heel in the housing, but also ensures a perfect sealing of the dispensing chamber at the level where the heel meets the body. This avoids any risk of leakage of fluid from the pump chamber at this level.
• the present invention also relates to a fluid dispenser comprising a fluid dispenser member as defined above and a fluid reservoir.
• the mounting piece is the tank.
• the mounting piece is an adaptation cup received on the reservoir, the cup comprising a ring in which the body of the dispenser member is mounted, the movable portion being moved into its final configuration when engaged in the ring.
• the adapter cup serves as a connecting piece between the dispensing member and the reservoir. It advantageously allows to mount a standard distribution member on several tank versions by modifying only this adapter cup.
• the ring of the cup remains identical, since the dispenser member is standard. However, the shape, size and configuration of the cup may be changed depending on the type of tank on which we want to mount the standard dispenser.
• the reservoir comprises a barrel and a follower piston slidably engaged in the barrel, the dispensing member is a pump without air intake.
• FIG. 1 is a vertical cross-sectional view through a fluid dispenser according to one embodiment of the invention
• FIG. 2 is a partial cross-sectional view of the dispenser member of the invention. Figure 1 just before mounting on the adapter cup.
• the dispensing member chosen to illustrate the present invention is a pump without air intake.

• the pump 1 is associated with an adapter cup 3, a reservoir 2, a pusher 4 and a cap 5 to form a fluid dispenser.
• Cap 5 is optional.
• the reservoir 2 is a variable volume reservoir. More particularly, the reservoir 2 comprises a substantially cylindrical barrel 22 inside which a follower piston 23 is slidably mounted. Initially, the follower piston 23 is located near the open bottom of the barrel 22. In this configuration, the reservoir defines a maximum useful volume 20 which will decrease as the follower piston 23 goes up inside the barrel 22.
• the tank also defines a neck 21 which is located here in the extension of the barrel 22. This neck 21 has means for a stable and sealed attachment of the cup 3 on the reservoir. In this case, the collar 21 internally defines one or more attachment profiles in the form of grooves and / or ribs.
• the adapter cup 3 is a mounting piece which makes it possible to fix the pump 1 to the tank 2.
• the pump 1 is not mounted directly on the tank 2, although this is entirely possible.
• the dispenser does not include an adapter cup, since the reservoir is itself the mounting piece on which the pump is mounted.
• the pump 1 is mounted on the adapter cup 3 which is itself mounted on the reservoir 2.
• the cup 3 comprises a gripping section engaged inside the neck 21.
• This attachment section 31 may be formed with one or more attachment profile (s) complementary to those of the neck 21.
• the cup 3 forms a peripheral flange 32 which protrudes radially outwards and which is intended to bear on the upper edge of the neck 21.
• the cup forms a flange 33 which can be used for the detachable snap-fastening of the cap 5 which can bear on the flange 32.
• the cup 3 extends downwardly from the hooking section 31 to form a substantially radial section 34 which extends inwardly by a mounting ring 35 which is substantially cylindrical.
• the ring 35 is open upwards and slightly closed downwards by a peripheral shoulder 36 which projects substantially radially inwards. This shoulder 36 may extend in the extension of the flange 34.
• the ring and the shoulder 36 together form a mounting housing 37 accessible axially from above.
• the pump 1 comprises in this embodiment four main constituent elements, namely a body 11, an inlet valve element 12, a flexible part 13, and a movable outlet valve member 14.
• the pump can to include fewer pieces, or on the contrary more pieces, without departing from the scope of the invention.
• the body 11 of the pump is the part which serves to support other elements constituting the pump, such as the flexible part 13 and the valve member 12.
• the body 11 is also the part which is directly mounted on the cup 3 to its mounting housing 37. Specifically, the body 11 is inserted into the ring 35 to abut on the shoulder 36.
• the body 11 defines a fluid product inlet 110 which is here in the form of a plurality of inlet holes. On the periphery of these holes, the body defines an inlet valve seat 112. This seat 112 is intended to cooperate with a movable inlet valve member 122 formed by the inlet valve element.
• the movable member 122 may be in the form of a disk or a washer which is axially displaceable or deformable.
• the body 11 forms a central chimney 111 in which the inlet valve member 12 is trapped. However, it can move on a small stroke allowing the movable member 122 to move relative to its seat 112.
• the body 11 On its outer periphery, the body 11 forms a housing 113 for holding and fixing a heel anchoring 131, as will be seen below.
• This housing 113 comprises a fixed internal wall 114 and a movable wall or external part 115. The displacement of the movable part 115 radially inwardly makes it possible to close the housing 113.
• the mobile part 115 is here formed by a external peripheral collar that surrounds the fixed inner wall 114 of concentric strap.
• the housing 113 is defined by an annular space delimited between the inner wall 114 and the deformable peripheral outer collar 115.

• the collar 115 may be continuous on its periphery, or alternatively, as shown in FIG.
• the collar may be interrupted by slots 117 which thus separate the collar in a plurality of paws or tongues.
• the flange may be internally provided with a projecting bead 116 which allows to further close the housing 113.
• the bead 16 engages just above the upper edge of the anchor heel 131 Starting from FIG. 2, it is easy to understand that the flange 115 will progressively be deformed radially inwards against the anchoring heel 131 as the pump
• the pump 1 as partially shown on FIG. FIG. 2 is in a pre-assembled or pre-assembled initial configuration in which the anchor heel 131 is inserted into the housing 113, but this housing 113 is not in its final mounting configuration. Only after mounting the pump in the adapter cup 3 that the housing reaches its final configuration of assembly.

• the flexible part 13 is preferably made in one piece from a relatively flexible plastic material when it has reduced wall thicknesses.
• the flexible piece 13 comprises an anchor heel 131 engaged in the housing 113, an elastically deformable membrane 132, a rigid plate 133 defining internally a shutter seat 134 and a rigid bushing 135 defining at its upper end a seat of outlet valve 136.

• the membrane 132 serves both piston and return spring. It is his memory that allows him to return elastically to its initial configuration of rest.
• the seat 134 of the plate 133 is engaged with a closure element 124 integrally formed by the inlet valve element 12. It may even be noted that the closure member 124 engaged with its seat 134 raises the movable member 122 of the inlet valve away from its seat 112. Thus, in the rest position, the inlet valve is open and communicates with the reservoir 2. On the other hand, the chamber 10 is closed at the sealing member 124 resting on its seat 134. This position exists only when the flexible membrane 132 is at rest. On the other hand, as soon as this flexible membrane is deformed, the movable member 122 comes to clap on its seat 112 and the shutter element 124 is detached from its seat 134.
• the chamber 10 is isolated from the tank 2 by the inlet valve closed but can communicate upwardly with the inside of the rigid sleeve 134.
