Abstract
An apparatus for facilitating the filling of a spray device, the spray device being constituted by a receptacle and an extraction and projection pump mounted on the receptacle. The pump is of the precompression type and includes a valve member (8) having a pin (9) which is held pressed against a seat (7) by a spring (10) whose characteristics determine the degree of precompression. The seat is formed around the axis of the delivery piston (4) of the pump, and wherein breakable or deformable projections (15) are formed on the valve member suitable for holding the valve open so long as said projections are not destroyed or deformed.
