ABSTRACT OF THE DISCLOSURE The specification of the present invention discloses an automatic bottle cap that may be applied to an opened receptacle. The value used in this cap automatically opens when the receptacle is tipped for pouring and closes when the receptacle returns to the upright position. The device uses two permanent magnets positioned such that a net unbalanced force exists be- tween them which is used to open or close the valve. The movement of one magnet within the structure causes the direction of the net unbalanced force to be reversed causing the second magnet and associated valve stem to move and open or close the valve.
