Definitions
- Fluid product distribution member with an offset offset channel Fluid product distribution member with an offset offset channel.
- the present invention relates to a fluid dispenser member intended to be mounted on the neck of a container.
- This type of dispensing member generally comprises a body defining a chamber in which a piston slides.
- a fixing member is often provided for fixing the dispensing member to the neck of the container.
- a discharge channel is often provided to convey the fluid product from the chamber to a dispensing orifice.
- a feature of the dispensing member of the present invention is that the dispensing member is fixed.
- Document WO 93/03857 describes a fluid dispenser member having a fixed dispenser orifice.
- This prior art dispensing member comprises a body in which is engaged a cylindrical part which defines the pump chamber with a piston.
- the piston surmounted by a pusher slides inside this cylindrical part housed inside the body of the dispensing member.
- the cylindrical part defines an outlet valve seat.
- the body is further provided with a fixing member in the form of a snap ring intended to cooperate with the outside of the neck of a container.
- a cap piece which defines a nozzle at the end of which is the fixed dispensing orifice. More precisely, the cap piece is screwed onto the body while maintaining the fixing member on the body.
- a delivery channel is provided which extends between the cylindrical part and the body.
- This delivery channel extends from the lower end of the cylindrical part to its upper end vertically when the dispensing member is upright.
- a groove is made in the internal wall of the body and this groove is sealed in isolation by the cylindrical piece attached to the interior of the body.
- this dispensing member it has four parts (apart from the piston), namely a body, a cylindrical piece, a fixing member and a cap piece.
- Document FR 2 714 027 also discloses a manual pump comprising an internal cylinder in which a piston slides and a body in which the cylinder is received.
- the external diameter of the cylinder is much smaller than the internal diameter of the body so that a space is defined between the cylinder and the body.
- This space has a crescent-shaped cross section because the cylinder is positioned offset in the body.
- This crescent shaped space defines a considerable volume which is a dead volume.
- the body extends upward to form a fixing ring on the outside of a container neck.
- the body of this pump comprises two separate parts, namely a skirt receiving the cylinder and a ring coming around a neck, the skirt and the ring being however connected together in a single piece. It should be noted that by coming to be fixed on the outside of the neck, the ring also increases the useful diameter of the pump.
- the present invention aims to remedy the aforementioned drawbacks of the prior art by defining a dispensing member having a minimum number of constituent parts while defining an offset offset delivery channel of reduced dead volume leading to a fixed dispensing orifice.
- the present invention provides a fluid dispenser member intended to be mounted on the neck of a container, said member comprising: a body defining a chamber in which a piston slides, - a fixing member intended to cooperate with the neck, said fixing member extending around the body, and a delivery channel connecting the chamber to a fixed dispensing orifice, said delivery channel being formed between the body and the fixing member, characterized in that the fixing member is able to cooperate with an internal wall of the neck to achieve a fixing of the dispensing member in the neck.
- the fixing member therefore serves both to form the delivery channel and to fix it in the neck.
- the fixing member comprises latching means intended to cooperate with at least one recess formed in the internal wall of the neck.
- the fixing member comprises a substantially cylindrical skirt defining internally the delivery channel with the body and externally latching means in the neck. The skirt thus fulfills a double function by itself.
- said delivery channel forms a groove in the external wall of the body, said fixing member comprising a skirt in contact with the body.
- the skirt is in tight contact with the body so that the groove made in the external wall of the body is insulated over its entire length.
- the channel extends substantially over the entire height of the body.
- the body is engaged by sealed sliding with friction in the skirt of the fixing member.
- the latching means comprise at least one projection intended to snap into at least one recess formed in the internal wall of the neck.
- the fixing member which is then practically invisible then fulfills a double function, namely that of isolating the groove with its internal wall and of snap-fastening with its external wall.
- the fixing member can then be summarized as a simple skirt enveloping the body of the dispensing member.
- the delivery channel opens near the fixed dispensing orifice. The fluid product flow path is thus reduced to its minimum, which reduces the pressure losses and makes it possible to soften the operation of the dispenser.
- the dispensing orifice is formed in the fixing member or in a nozzle received in a housing formed in the fixing member.
- the single figure is a section in vertical cross section through a dispensing member according to the invention mounted on a container neck.
- the dispensing member shown in the single figure is a pump comprising a pump body 2 defining a barrel in which slides a piston 4 mounted at the end of an actuating rod 5 equipped at its upper end a pusher 51.
- the pump body 2 defines with the piston 4 a pump chamber 43 of variable volume having an inlet 230 communicating with the interior of a reservoir and an outlet 231.
- a return spring 52 brings the piston back 4 in a rest position in which the volume of the pump chamber 43 is maximum.
- a ferrule 6 is provided forcibly engaged inside the pump body 2 at its upper end. This is a completely conventional design for a fluid pump such as may be encountered in the fields of perfumery, cosmetics and pharmacy.
- a fixing member 3 in the form of a fixing ring which cooperates with the neck 10.
- this type of fixing ring cooperates with the external wall of the neck 10 which forms a reinforcement.
- a fixing ring which cooperates with the internal wall 11 of the neck 10.
- the internal wall 11 of the neck 10 forms at least one recess 12
- the fixing ring 3 comprises a skirt 30 which forms on its external wall at least one projection 32 intended to snap into the interior of the recess 12. At its upper end , the skirt 30 forms a shoulder 33 intended to come to bear on the upper end of the neck 10.
- the fixing ring 3 forms a housing 34 in which is mounted a nozzle 8 which forms a fixed distribution orifice 81.
- This orifice can alternatively also be directly formed in the fixing ring 3.
- the ring forms a channel outlet 35 and channels and a swirl chamber 36.
- a covering band 9 can also come to cover the fixing ring so as to hide it as well as the neck 10.
- the body 2 of the pump is engaged inside the skirt 30 of the ring 3.
- the outlet from the pump chamber 43 is formed in the pump body 2 and connects the nozzle 8 through a discharge channel 23.
- the discharge channel 23 is formed between the body 2 and the fixing ring 3, in particular its skirt 30.
- the external wall of the body 2 is formed with a groove which extends from the outlet 231 to another bore 232 produced through the wall of the pump body.
- the skirt 30 completes the groove made in the body of the pump to isolate and thus form the delivery channel 23.
- the product arrives in a chamber 73 of variable volume.
- An outlet valve is produced in the form of a differential piston and is slidably mounted on the ferrule 6 and is elastically constrained by the spring 52 which therefore serves both as a return spring and as a precompression.
- the differential piston 7 moves upwards and releases another bore 25 formed in the body 20 which communicates with the outlet duct 35 produced by the fixing ring 3.
- the dispensing member which can of course undergo numerous modifications without departing from the spirit of the invention which resides in the fact that the delivery channel 23 is formed between the fixing member, in this case the skirt 30 of the ring 3, and the pump body 20. It is also advantageous for the fixing member to cooperate with the internal wall of the neck so that the same piece, namely the skirt 30, fulfills a double function using these internal and external walls.
