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.
Claims14
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.
