Abstract
A device for spraying or dispensing a fluid and adapted to be mounted on a fluid tank 30 includes a body 1, an actuator member 3 slidably mounted relative to the body, an inlet passage 14 communicating with the tank and enabling the fluid to enter into the body, and an elongate member 5, 25 slidably mounted in the inlet passage and penetrating into the tank. The elongate member is displaceable together with the actuator member towards the tank on the first occasion that the actuator member is actuated, and the elongate member exerts mechanical action on an element 33, 42 secured to the tank when it is displaced, and in such a manner as to puncture or dislodge the element.
