  • Patent number: 4893552
    Abstract: A beverage making machine includes a housing with structure defining a storing receptacle receiving region and support structure above the storing receptacle receiving region, and filter case structure for releasable engagement with that support structure. The filter case structure has an outlet in which an anti-drip valve is disposed. A valve operating mechanism includes biasing means for biasing the valve to its closed position, and one piece lever structure is connected between the biasing means and the valve for moving the valve to its open position. The one piece lever structure is deflectable about a first axis of rotation by a stop on the housing as the filter case structure is inserted into the beverage making machine without opening said anti-drip valve, and, insertion of the storing receptacle beneath said filter case structure moves the lever about a second axis of rotation to open the anti-drip valve.
