Abstract: A device for delivering a pellet, the device having: a base intended to be assembled to a neck of a recipient, including a skirt and a transverse wall presenting an orifice; a cap mounted coaxially on and around the base, including a transverse wall and a skirt presenting an aperture and wherein protrusions formed on the cap are displaced in grooves formed on the base so that the cap can be displaced between: a closed position, in which the transverse faces of the base and of the cap are adjacent, the orifice and the aperture being closed; and an open position, where, between the base and the cap, is created an intermediate chamber in which a pellet contained in the recipient can enter via the orifice of the base, and then come out via the aperture of the cap.
