Abstract
This assembly is of the type including: a container (4) for containing the liquid; a liquid dispensing device (6), including: a spout (20) through which liquid can pass out and air can come in; and elements (28) for filtering liquid and air passing through the spout (20); and a cap (14) for closing the container (4). One feature of the invention is that the assembly includes elements (38, 41, 39) for encouraging the entrance of air and/or the return of a residual quantity of liquid trapped in the spout (20) after dispensing some liquid, through the filtering elements (28), into the container (4).
Claims18
Assembly for containing and dispensing a liquid, comprising:
- a container (4) for containing the liquid;
- a liquid dispensing device (6), comprising:
- a spout (20) through which liquid can pass out and air can come in;
- and
- means (28) for filtering liquid and air passing through the spout (20);
- and
- a cap (14) for closing the container (4);
- and
- means (38, 41, 39) for encouraging the entry of air and/or the return of a residual quantity of liquid trapped in the spout (20) after dispensing some liquid, through the filtering means (28), into the container (4),
- characterised in that the means for increasing the entry of air and/or the return of a residual quantity of liquid comprise sealing means (38, 41) capable of closing in a sealed manner a space (42) located between the spout (20) and the partially-closed cap (14), the volume of which decreases as closure of the cap (14) progresses, so as to create an overpressure in the spout (20) downstream of the filtering means (28), due to the cap (14) being closed.
