Abstract

The present invention relates generally to a magnetic valve system. Embodiments of the present invention provide a system to minimize the potential for mistakenly dispensing one fluid in place of another or desired fluid. More particularly, embodiments of the present invention provide a magnetic valve, where a bias mechanism is provided to bias the magnetic valve into a closed position, whereby a receptacle having a magnet with a magnetic polarity arranged opposite to that of the magnetic valve exerts a force on the magnetic valve sufficient to over come the bias mechanism, and the magnetic valve slides into an open position or state permitting fluid to flow into the receptacle. When the receptacle is removed, the bias mechanism forces the magnetic valve back into the closed position, where no or minimal fluid is permitted to flow.
