Definitions
- the present invention relates to a fluid dispenser device such as a pump or a valve intended to be mounted on a container neck so as to form a fluid dispenser.
- a fluid dispenser device such as a pump or a valve intended to be mounted on a container neck so as to form a fluid dispenser.
- Such dispensing devices are widely used in the field of perfumery, cosmetics or even pharmacy for dispensing liquid to pasty products.
- this type of device comprises a body in which a piston slides by pressing on a pusher, as well as a fixing member for fixing the body to the neck of the container.
- a dip tube can also be used to bring the fluid from the container to the inside of the body, this dip tube comprising a free end located near the bottom of the container and an upper end fixed to the dispensing device.
- the upper end of the dip tube is fixed to the body of the device which for this purpose forms a connection sleeve into which the end of the dip tube is inserted by force.
- the object of the present invention is to propose another solution for fixing the dip tube to the dispensing device.
- connection means for fixing the dip tube to the dispensing device are formed by the fixing member.
- the fixing member is in fixing engagement with an internal wall of the container neck.
- fixing socket it is meant that it is the contact of the fixing member with the internal wall of the neck which ensures the fixing of the body on the neck.
- the fixing member thus extends towards the bottom of the body, preferably by surrounding it with a tight contact, to form at its lower end the connection means which may advantageously be in the form of a similar connection sleeve. to that of a conventional body of the prior art described.
- the fixing member forms an inlet valve seat for a movable inlet valve element.
- the inlet valve seat is formed by the connection sleeve.
- the body and the fixing member together form an inlet valve chamber in which a movable valve element is trapped.
- At least part of a channel for discharging the fluid product out of the body extends between the fixing member and the body.
- the fixing member comprises means for snapping into the neck.
- the invention also relates to a fluid dispenser equipped with such a dispensing device.
- Figure 1 is a vertical cross-sectional view through a fluid dispenser device according to a first embodiment of the invention mounted on a container neck.
- Figure 2 shows a variant of Figure 1.
- the fluid dispenser used to illustrate the present invention is a pre-compression pump, but one could also have used another pump or even a valve.
- the pump shown in the figures is a fixed spray pump, that is to say provided with a fixed dispensing orifice which does not move when the pump is actuated.
- This is a special type of pump, and another mobile spray pump could have been used to illustrate the present invention.
- the pump comprises a pump body 2 defining a cylindrical part 20 a flange 22 connected to the upper end of the cylindrical part 20 and a lower part 21 connected to the lower end of the cylindrical part 20.
- the pump body 2 is open at both ends.
- a piston 3 slides in the pump body 2 at its cylindrical part 20.
- the piston 3 is mounted on an actuating rod 34 surmounted by a pusher 35 which is pressed to move the piston with a sealed slide inside the cylindrical part 20 of the pump body 2.
- a return spring 57 biases the piston 3 in the rest position which defines the maximum volume of the pump chamber -23. In the rest position shown in the figures, the piston 3 is supported on a ferrule 6 engaged by force in the pump body 2. The ferrule 6 therefore defines the top dead center of the pump.
- the ferrule 6 defines a central opening through which the actuating rod 34 slides.
- the ferrule 6 also serves as a fulcrum for a movable top valve member 7 which can move on the ferrule 6.
- the return spring 57 is supported on the one hand under the pusher 35 and on the other hand on the top movable valve member 7.
- the high valve member may be in the form of a cuff which can slide freely on the actuating rod 34 which defines an internal duct through which the product flows from the chamber 23 for regain a dispensing orifice formed in the pusher 35.
- the top movable valve member 7 slides on the other hand in the pump body 7 at the flange 22.
- the pump also comprises a fixing member 8 which makes it possible to fix the pump body 2 on the neck 10 of a container 1.
- the fixing member 8 cooperates with the inner wall 11 of the neck 10.
- the fixing member 8 comprises a skirt 80 forming on its outer wall a boss 81 intended to be housed in a recess 12 formed in the inner wall 11 of the neck 10. This is a snap fastening which can advantageously be blocked by means of the ferrule 6 or pump body 2.
- the dispensing device of the invention is also provided with a dip tube 9 which is partially shown in the - figures. In fact, only the fixed upper end 90 of this dip tube 9 is shown.
- the dip tube 9 is fixed to the pump by means of a sleeve. connection 85 formed by the fixing member 8.
- the skirt of the fixing member 8 is extended downwards by a bottom part 87 at the lower end of which the connection sleeve 85 is formed.
- the dip tube 9 is forcibly inserted into the sleeve 85 with its upper end 90 until it abuts against a shoulder 88 formed in the connection sleeve.
- the pump body 2 is inserted inside the fixing member 8 with a tight tight contact at the level of the cylindrical part 20 and the lower part 21.
- the pump body 2 is open at its lower end through which passes the connection sleeve 85 so that the dip tube communicates directly with the interior of the pump chamber 23.
- the upper end of the sleeve 85 forms an inlet valve seat 86 on which is disposed a movable valve element 4 which can move in a limited manner inside a chamber 48 formed jointly by the fixing member 8 and the lower part 21 of the pump body 2.
- the element movable valve 4 may be in the form of a ball, but also in the form of a molded plastic part as shown in the figures.
- valve seat 210 is conventionally formed by the body 2 of the pump at its lower part 21.
- the movable valve element 4 is trapped in the body which forms a throttle 211 through which the valve element 4 can move in a limited way by lugs 45.
- the pump chamber 23 communicates with the nozzle 84 via a delivery channel 28 formed between the pump body 2 at its cylindrical part 20 and the fixing member 8 at the level of its skirt 80.
- the isolation of this discharge channel 28 is possible because the fixing member 8 is in tight sealing contact with the pump body 2.
- the fluid product discharged by the piston 3 from the chamber 23 passes through the discharge channel 28 to reach the outlet valve element 7 which is then pushed by the pressurized product so as to release the hole which communicates with the outlet orifice 83.
- an air return channel 29 is also formed between the fixing member 8 and the pump body 2 to allow external air to penetrate inside the container as the product fluid is distributed by the pump. This return air channel 29 is formed similarly to the discharge channel 28.
- nozzle 84 is housed in an appendage 82 formed by the fixing member 8.
- the fastener 8 of the present invention therefore fulfills multiple functions, namely that of fixing the body to the neck, that of connection means for the dip tube, that of the inlet valve seat, that of housing for the nozzle 84, that for forming the discharge channel 28 and that for forming the return air channel 29. This saves several parts.
