A refillable closed container (1) that cannot be refilled without the use of a special mechanism. The refillable closed container system comprises a valve body (13) secured in an opening of the container (3), a flow passage through the valve body for permitting flow into and out of the container, a magnetically attractable valve member (17) in the valve body, and a magnet carrier (61). The valve member is movable between a closed position for blocking flow through the passage and an open position for permitting flow through the passage. The magnet carrier carries a magnet (65) for magnetical ly moving the valve member toward an open position when the magnet carrier is secured to the container to permit refilling of the container. |
