<p>The closure device (10) comprises a body (12) intended to be mounted onto the mouth of a container (C), a cap (14) which covers the body (12) from the top and encloses it laterally and which is rotatably mounted onto the body (12) to rotate between a closed position and an open position, and a spring (16) interposed between the body (12) and the cap (14) to apply onto the cap (14) a biasing torque tending to bring it back into the closed position. The body (12) and the cap (14) have a first opening (24) and a second opening (62), respectively, which in the closed position are angularly offset with respect to each other to prevent the product contained in the container (C) from being dispensed and in the open position are aligned with each other to allow the product contained in the container (C) to be dispensed. The body (12) and the cap (14) are advantageously made of moulded plastic material.</p> |
