- a fluid reservoir such as for example a bottle or a can of water, drink or more generally of fluid product .
- the nature of the contents of the tank does not of course limit the present invention, which also relates to the use of such a head mounted on a tank.
- the particular type of fluid dispensing head according to the invention comprises a dispensing valve which can be moved elastically between a closed position in which the fluid product cannot flow from the reservoir through the head and an open position in which the fluid product can flow from the reservoir through the head, and a manually operable control member for bringing the dispensing valve from its closed position to the open position.
- the valve includes a seat and a movable member in sealed contact in the closed position and detached from one another in the open position.
- part of the dispensing valve moves relative to another part to release a flow passage for the fluid product from the reservoir.
- the control member generally constitutes a separate part associated during assembly with the distribution valve. Therefore, it is very common that such a dispensing head is made up of several separate parts which are assembled together to form the dispensing head.
- the manufacturing process requires the implementation of several different molds and the assembly process requires the assembly of several separate parts.
- the object of the present invention is to simplify both the manufacture and the mounting of such a fluid product dispensing head.
- at least one element constituting the head is produced by co-molding of two different plastics.

- the annular movable member comprises a rigid bushing comprising an annular free end intended to come into tight contact with the seat in the closed position and flow passage forming means intended to come into non-tight contact with the seat in open position.
- the means for forming a flow passage comprise longitudinal ribs or fins formed on an external wall of the sleeve above the free annular end.
- the rigid sleeve with its external longitudinal ribs and its free annular end is moved relative to the elastically deformable annular lip connected to the fixed rigid sleeve.
- This has the effect of bringing the longitudinal ribs into contact with the lip which comes off from the free annular end.
- several flow passages are formed between the ribs in contact with the lip.
- the cover forms the control member.
- the hood control member comprises a movable bearing surface, the second part being integral in displacement with the bearing surface, the cover further comprising a rigid external crown in watertight engagement with the base in the final mounting position, said crown being connected to the bearing surface and to the second part by an elastically deformable membrane.
- the membrane is made of an elastomeric plastic material, the membrane being connected by co-molding on the one hand to the crown and on the other hand to the bearing surface and to the second part, the crown, the surface support and the second part being made of a harder plastic material.
- the elastically deformable membrane fulfills a return spring function making it possible to return the control member and its second associated valve part to the rest position, corresponding to the closed position of the valve.
- the membrane is produced by co-molding or bi-injection of an elastomeric material inside the single mold into which is also injected a harder or more rigid plastic which forms the remainder of the head. distribution.
- the dispensing head comprises an inlet space separated from an outlet space by said valve, said outlet space extending concentrically around the inlet space.
- the base forms a dispensing orifice communicating upstream with the outlet space.
- the base can form an air intake hole communicating with the outlet space.
- the present invention also relates to the use of such a dispensing head in the supine position with the dispensing orifice facing downward and the air intake hole facing upward, the fluid product coming from the reservoir. reaching the head by gravity.

- - FIG. 1 is a slightly perspective view from above of a fluid dispensing head according to the invention in the initial position at the outlet of the mold
- - Figure 2 is a vertical cross-sectional view at through the dispensing head of FIG. 1
- - FIG. 3 is a perspective view of the dispensing head of the preceding figures in final mounting position ready for use
- the dispensing head comprises a base 1 and a cover 2 connected together by a joint 112.
- the base 1 and cover 2 are preferably made in a single piece in a single mold by plastic injection.
- One or more plastics of different natures can be used.
- two or three materials of different rigidity are used.
- the imprint of the joint 112 constitutes a point of passage of material between the base 1 and the cover 2. It can also be envisaged that the cover is not connected to the base.
- the base 1 comprises an outer ring 11 of generally substantially cylindrical shape.
- the ring 11 forms a dispensing orifice 12 and an air intake hole 13.
- the base 1 also comprises a skirt 14 which extends concentrically inside the lower part of the ring 11.
- the skirt 14 is intended to come into engagement with an opening or a neck of the fluid reservoir.
- the base 1 also comprises a sleeve 15 which extends concentrically inside the upper part of the ring 11.
- the skirt 14 is connected to the sleeve 15 by an annular flange 145.
- the skirt 14 and the sleeve 15 internally form an inlet space 10 which allows the fluid stored inside the tank to flow through the head.
- the sleeve 15 is further provided with an annular sealing lip 16, which is here Tonic-shaped.
- the lip 16 can be made from a material different from that of the remainder of the base 1.
- the lip 16 and the remainder of the base can however be co-molded in a single mold using '' a bi-injection technique.
- the lip can be made of a plastic material of the elastomer type, while the rest of the base can be made of a harder or rigid plastic material.
- the sleeve 15 and the upper part of the ring 11 at which the dispensing orifice 12 and the intake hole 13 are formed together form an annular dispensing space 18, the bottom of which is formed by the annular flange 145.
- the distribution space extends concentrically around the entry space.
- the cover 2 includes a substantially rigid outer ring 23 which is connected to the base by the joint 112.
- a socket 21 extends substantially centrally and axially in the ring 23.
- the socket 21 is connected to the ring 23 by at least one connecting flange 24.
- the socket 21 comprises a bottom 25.
- the socket 21 also comprises several radial fins 22 which extend on the outer periphery of the socket 21.
- the free end 211 of the socket is however free of 'fin so as to form a perfectly cylindrical section. This is clearly visible in Figure 1.
- the sleeve 21 is certainly connected to the crown 23 by one or two connecting flange (s) 24: however, the sleeve 21 is also connected to the crown 23 by an elastically deformable membrane 26 which has a frustoconical annular shape.
- the membrane is fixed to the crown on the outer periphery and to the sleeve on the inner periphery.
- This membrane 26 can be made of a material different from the rest of the cover 2.
- the membrane can be made of elastomer while the rest of the cover can be made of a harder material than the membrane.
- the membrane 26 and the remainder of the cover can be molded in a single mold by a bi-injection technique, such as the lip 16.
- the dispensing head 1 leaves the single mold in the configuration shown in FIGS. 1 and 2: the free end 211 of the sleeve points upwards and the bottom 25 downwards.
- the cover 2 is then folded down by pivoting on the base 1 so as to snap the crown in a sealed and definitive manner 23 inside the ring 11. This is shown in FIGS. 3 and 4.
- the sleeve 21 is then partially engaged in the sleeve 15 with the lip 16 which comes into contact with the lower edges 221 of the fins 22, but also with the fiber end 211 of the socket.
- the free end of the lip 16 comes into peripheral sealed contact around the periphery of the sleeve 21, by pressing on the lower edges 221.
- the lip 16 and the sleeve 21 with its ribs with fins 22 together form a valve. distribution, the base forming a first part with the lip and the cover forming a second part with its rib socket.
- the valve is only formed and operational in the end mounting position of FIGS. 3 to 5. In the initial configuration or position for leaving the mold, the first part is separated from the second part of the valve.

- the fins 22 of the socket 21 will force the lip 16 to deform and break its tight contact with the perfectly cylindrical part 211 formed at the free end of the socket 21.
- the fluid product coming from the inlet space 10 can then flow between the fins 22 to reach the outlet space 18 formed around the sleeve 15. From there, the fluid can flow through the dispensing orifice 12.
- air can penetrate through the intake hole 13 in the space 18 and then pass between the fins 21 and then in the space 10 to the interior of the tank.
- the purpose of the air entry through the hole 13 is to compensate for the quantity of fluid distributed towards the orifice 12.
- the elastically deformable membrane 26 returns to its closed rest position, in which the free end of the lip 16 comes into sealed contact on the cylindrical part 211 of the sleeve 21.
- the dispensing head is then closed again.
- the head can be produced in a single or two elements) constituting) distinct, at least one of the elements (base-cover) being produced by co-molding bi-material or tri-material.
- the lip 16 can for example be made in one piece with the same material as the rest of the base.
- the free end 211 can be made of a material different from that of the remainder of the sleeve, and even of the membrane 26
- a preferred use of this dispensing head is that in which the head is arranged in a supine manner as shown in FIGS. 3, 4 and 5.
- the dispensing orifice 12 is located at the bottom, while the hole 13 is oriented towards the high.
- the fluid which flows between the fins 22 in the outlet space 18 will reach by gravity the level of the dispensing orifice 12.
