Abstract: An actuating assembly for dispensing a product under pressure is provided, which includes a shoulder mounted on a device for sampling the product under pressure, and a button with an inner actuator having a upstream spout mounted in a feeding tube and a downstream spout in communication with the upstream spout which terminates in a dispensing outlet, wherein the button has an outer cover with a peripheral skirt and a dispensing hole, and wherein the outer cover is mounted on the actuator in a actuating position in which the hole is arranged opposite the outlet to allow the product to be dispensed through the hole. The button is also axially displaceable with respect to the shoulder in a dispensing and aspiration stroke, and the cover is reversibly mounted on the actuator from an actuating to an inactive position and is arranged in order to prevent axial displacement of the button.

Abstract: An actuating assembly for a system for dispensing a product under pressure, which comprises a shoulder to be mounted on a device for sampling the product under pressure, which further comprises a press button with an inner actuator having a upstream spout to be mounted in a feeding tube of the device, wherein said actuator comprises a downstream spout in communication with said upstream spout and terminates in a dispensing outlet, said button comprises an outer cover with a peripheral skirt in which a dispensing hole is formed, wherein said cover is mounted on said actuator in a actuating position in which the hole is arranged opposite the outlet to allow said product to be dispensed through the hole and wherein the button is axially displaceable with respect to the shoulder in a dispensing/aspiration stroke, the cover is reversibly mounted on the actuator from the actuating position to an inactive position, in which the geometric means formed in the cover are arranged to cooperate with the complementary geom
