Abstract

A fluid dispenser comprising:
a fluid reservoir ( 1 ) that is transparent, at least locally; and a guide tube ( 21 ) that extends in the reservoir ( 1 ); the dispenser being characterized in that it further comprises a gauge ring ( 19 ) that is engaged freely around the guide tube ( 21 ) and that floats in the fluid in such a manner as to indicate visually the fluid level in the reservoir.

First claim

The invention claimed is:

1. A fluid dispenser comprising:
a fluid reservoir that is transparent, at least in part; and
a guide tube that extends in the reservoir;
the dispenser further comprising a gauge ring that is engaged freely around the guide tube and that, when the reservoir contains a fluid, floats in the fluid in such a manner as to indicate visually the fluid level in the reservoir;
wherein the reservoir includes a bottom wall provided with a filling valve, and a vent passage for allowing air from the reservoir to escape while the reservoir is being filled through the valve, and
wherein the guide tube extends in proximity of the bottom wall of the reservoir, the filling valve comprising a valve seat formed in the bottom wall of the reservoir and a valve member received in the reservoir and further comprising a closure pin for selectively coming into leaktight contact with the valve seat, the pin being connected to resilient drive elements, the guide tube pressing on the resilient elements so as to urge the pin against the seat.

2. The dispenser according to claim 1 , wherein the reservoir includes at least one bottom window and one top window through which the gauge ring is visible.

3. The dispenser according to claim 2 , wherein the windows are provided with magnifying lenses.

4. The dispenser according to claim 1 , further comprising:
a dispenser member; and
fastener means for fastening the dispenser member on the reservoir;
wherein the guide tube is formed by the fastener means, the dispenser member being engaged in the guide tube.

5. The dispenser according to claim 4 , wherein the ring comes into leaktight contact with the fastener means when the reservoir is full.

6. The dispenser according to claim 1 , wherein the gauge ring bears on the valve member when the reservoir is empty.

7. The dispenser according to claim 1 , further comprising a dispenser member, the dispenser being provided with a dip tube that extends into the reservoir, the guide tube surrounding the dip tube so as to guide the dip tube into the reservoir.

8. The dispenser according to claim 1 , further comprising a dispenser member, wherein the vent passage is closed selectively by closure means that are actuated by turning a pusher that is mounted on the dispenser member.

9. The dispenser according to claim 1 , further comprising a dispenser member that is a pump.

10. The dispenser according to claim 1 , further comprising a dispenser member, the dispenser member being provided with a dip tube that extends into the reservoir, the guide tube surrounding the dip tube so as to guide the dip tube into the reservoir at the bottom of the reservoir.

11. A fluid dispenser comprising:
a fluid reservoir that is transparent, at least in part; and
a guide tube that extends in the reservoir;
a gauge ring engaged freely around the guide tube and that, when the reservoir contains a fluid, floats in the fluid in such a manner as to indicate visually the fluid level in the reservoir;
a dispenser member; and
a fastener ring that fastens the dispenser member on the reservoir; and
wherein the guide tube is formed by the fastener ring, the dispenser member is engaged in the guide tube, and the gauge ring comes into leaktight contact with the fastener ring when the reservoir is full.

12. The dispenser according to claim 1 , further comprising a dispenser member provided with a dip tube that extends into the reservoir, and the guide tube surrounds the dip tube.

13. The dispenser according to claim 11 , wherein the dispenser member is provided with a dip tube that extends into the reservoir, and the guide tube surrounds the dip tube.

14. A fluid dispenser comprising:
a fluid reservoir that is transparent, at least in part; and
a guide tube that extends in the reservoir;
a gauge ring that is engaged freely around the guide tube and that, when the reservoir contains a fluid, floats in the fluid in such a manner as to indicate visually the fluid level in the reservoir; and
a dispenser member,
wherein a vent passage is closed selectively by closure means that are actuated by turning a pusher that is mounted on the dispenser member, and
wherein the reservoir includes a bottom wall provided with a filling valve, and the vent passage for allowing air from the reservoir to escape while the reservoir is being filled through the valve.
