Abstract

A fluid dispenser comprising: a reservoir (1) serving to contain fluid and defining an actuating wall (14); and a dispensing orifice (20) via which the fluid is dispensed each time the wall (14) of the reservoir (1) is actuated; the reservoir (1) further containing a pump (3) defining a pump chamber (31) provided with an inlet valve (32) for communicating with the reservoir (1) and with an outlet valve (33), the pump (3) including a pusher (34) which is pushed in order reduce the volume of the pump chamber, said pusher (34) being disposed below the actuating wall (14) of the reservoir; said dispenser being characterized in that a delivery duct (21) connects the outlet valve (33) of the pump (3) to the dispensing orifice (20).

Claims

1. A fluid dispenser comprising:

a reservoir (1) serving to contain fluid and defining an actuating wall (14); and

a dispensing orifice (20) via which the fluid is dispensed each time the wall (14) of the reservoir (1) is actuated;

the reservoir (1) further containing a pump (3) defining a pump chamber (31) provided with an inlet valve (32) for communicating with the reservoir (1) and with an outlet valve (33), the pump (3) including a pusher (34) which is pushed in order reduce the volume of the pump chamber, said pusher (34) being disposed below the actuating wall (14) of the reservoir;

a delivery duct (21) connecting the outlet valve (33) of the pump (3) to the dispensing orifice (20),

said dispenser being characterized in that the pusher of the pump (3) is formed by a deformable wall (34) of the pump chamber (31).

2. A dispenser according to claim 1, in which the dispensing orifice (20) is defined by a pump support piece (2) to which the pump (3) is fitted.

3. A dispenser according to claim 2, in which the reservoir (1) is fixed to the support piece (2).

4. A dispenser according to claim 1, in which the reservoir (1) is made up of two deformable sheets (11, 12) sealed together around their peripheries (10).

5. A dispenser according to claim 4, in which the support piece is provided with a fixing appendage (23) to which the sheets (11, 12) of the reservoir (1) are fixed, advantageously by sealing.

6. A dispenser according to claim 1 in which the pusher of the pump (3) is formed by a deformable wall (34) of the pump chamber.

7. A dispenser according to claim 1, in which the support piece (2) forms a recess (24) into which component members of the pump (3) are inserted.

8. A dispenser according to claim 2 in which the support piece (2) defines a valve seat (27) for the inlet valve (32) of the pump.
