Lid with ventilation system

摘要

A lid (2) for a reservoir (1) to be connected to a liquid spraying device, comprising a ventilation hole (3); a flexible tube (4); and a valve (5), wherein the combination of the ventilation hole (3), the flexible tube (4), and the valve (5) forms a ventilation system which allows an air movement from the outside of the reservoir (1) via the ventilation system to the inside of the reservoir (1) while it blocks the movement of a liquid (6) from the inside of the reservoir (1) via the ventilation system to the outside of the reservoir (1).

1. A lid for a reservoir to be connected to a liquid spraying device, comprising:
a lid portion defining a cavity; a ventilation hole; a flexible tube; and a valve, wherein a combination of the ventilation hole, the flexible tube, and the valve forms a ventilation system which allows an air movement in a first direction, from the ventilation hole and through the flexible tube and valve, while blocking movement of a liquid in a second direction opposite the first direction, from the valve and through the flexible tube and ventilation hole; and wherein the tube is sufficiently flexible to deflect from an original position to a bent position, in which the tube and valve are at least partially received within the cavity.
