Abstract

A fluid dispenser having:a fluid reservoir (1);an applicator (2); and a dispenser module (3) that is arranged between the reservoir (1) and the applicator (2); the fluid dispenser being characterized in that the dispenser module (3) includes an air pump (4) for sending air into the reservoir (1), and a fluid duct (54) connecting the reservoir (1) to the applicator (2).

First claim

The invention claimed is:

1. A fluid dispenser comprising:
a fluid reservoir;
an applicator; and
a dispenser module that is arranged between the reservoir and the applicator; wherein the dispenser module includes an air pump for sending air into the reservoir, and a fluid duct connecting the reservoir to the applicator wherein the air pump connects the fluid reservoir through a one-way outlet valve; wherein the air pump connects to air outside of the device through a one-way inlet valve; and wherein the one-way outlet valve and the one-way inlet valve are formed by a single-piece valve member.

2. The fluid dispenser according to claim 1 , wherein the dispenser module includes reception housings in which the fluid reservoir and the applicator are respectively received.

3. The fluid dispenser according to claim 1 , presenting a configuration that is elongate along a longitudinal axis X, the reservoir, the applicator, and the dispenser module extending along the longitudinal axis X, with the dispenser module interposed between the reservoir and the applicator.

4. The fluid dispenser according to claim 1 , wherein the air pump includes a deformable actuator wall.

5. The fluid dispenser according to claim 1 , wherein the air pump comprises a single piece forming a pump chamber and a deformable actuator wall.

6. A fluid dispenser according to claim 1 , wherein the air pump extends beside, or all around, the fluid duct.

7. A fluid dispenser according to claim 1 , wherein the reservoir is transparent and does not have a dip tube.

8. A fluid dispenser comprising: a fluid reservoir; an applicator; and a dispenser module that is arranged between the reservoir and the applicator; wherein the dispenser module includes an air pump for sending air into the reservoir, and a fluid duct connecting the reservoir to the applicator, wherein the dispenser module comprises:
a module body forming the fluid duct and fastener means for fastening on the reservoir;
a cover forming reception means for receiving the applicator; and
the air pump in the form of a single-piece air expeller forming a pump chamber and a deformable actuator wall for actuating the air pump.

9. A fluid dispenser according to claim 8 , wherein the module body forms valve seats for a single-piece valve member respectively forming a one-way outlet valve connecting the air pump to the reservoir, and a one-way inlet valve connecting the outside to the air pump.

10. The fluid dispenser according to claim 8 , wherein the dispenser module includes reception housings in which the fluid reservoir and the applicator are respectively received.

11. The fluid dispenser according to claim 8 , presenting a configuration that is elongate along a longitudinal axis X, the reservoir, the applicator, and the dispenser module extending along the longitudinal axis X, with the dispenser module interposed between the reservoir and the applicator.

12. The fluid dispenser according to claim 8 , wherein the air pump comprises a single piece forming a pump chamber.

13. The fluid dispenser according to claim 8 , wherein the air pump extends beside, or all around, the fluid duct.

14. The fluid dispenser according to claim 8 , wherein the reservoir is transparent and does not have a dip tube.

15. A fluid dispenser comprising: a fluid reservoir; an applicator; and a dispenser module that is arranged between the reservoir and the applicator; wherein the dispenser module includes an air pump for sending air into the reservoir, and a fluid duct connecting the reservoir to the applicator,
wherein the dispenser module comprises:
a module body forming fastener means for fastening on the reservoir, and a bottom portion of the fluid duct;
a cover forming reception means for receiving the applicator, and a top portion of the fluid duct; and
a flexible sleeve that connects the module body to the cover so as to form between the module body and the cover the air pump, the flexible sleeve forming a deformable actuator wall for actuating the air pump.

16. The fluid dispenser according to claim 15 , wherein the module body forms valve seats for a single-piece valve member respectively forming a one-way outlet valve connecting the air pump to the reservoir, and a one-way inlet valve connecting the outside to the air pump.

17. The fluid dispenser according to claim 15 , wherein the dispenser module includes reception housings in which the fluid reservoir and the applicator are respectively received.

18. The fluid dispenser according to claim 15 , presenting a configuration that is elongate along a longitudinal axis X, the reservoir, the applicator, and the dispenser module extending along the longitudinal axis X, with the dispenser module interposed between the reservoir and the applicator.

19. The fluid dispenser according to claim 15 , wherein the air pump comprises a single piece forming a pump chamber and a deformable actuator wall.

20. The fluid dispenser according to claim 15 , wherein the air pump extends beside, or all around, the fluid duct.

21. The fluid dispenser according to claim 15 , wherein the reservoir is transparent and does not have a dip tube.
