A nozzle apparatus for infusing a liquid from a liquid reservoir into a vessel or bottle located lower than the reservoir. The nozzle apparatus comprising an outer cylindrical wall member having the interior communicated with the reservoir and filled with a liquid to be infused, an inner cylindrical wall member coaxially arranged in the interior of the outer cylindrical wall member for axial movement therein, a valve member adapted to close communication between the interiors of the outer and the inner cylindrical wall members, and an air-relief conduit member supported on the outer wall member and extending through the outer and the inner wall members and the valve member to terminate as a distal end which is adapted to be inserted in a vessel to be infused with a liquid. When the vessel is elevated by suitable means toward the nozzle apparatus, the vessel pushes the inner wall member upwards to a position allowing the valve to open for infusion of a liquid.
A nozzle apparatus for infusing a liquid from a liquid reservoir into a vessel, said vessel being located below said liquid reservoir, comprising an outer wall cylindrical member secured to the bottom of said reservoir providing a first chamber separate from said reservoir adapted to be filled with a liquid held in said reservoir, an inner wall cylindrical member fitted in said outer wall cylindrical member for axial movement therein providing a second chamber, valve means between said first and second chambers and adapted to connect and disconnect between said first and second chambers, air-relief conduit means rigidly carried by said outer wall cylindrical member and extending through said outer wall cylindrical member, said valve means and said inner wall member, the distal portion of said air-relief conduit means being adapted to be received in a vessel for said liquid to be infused into, elevation of said vessel causing said inner wall cylindrical member to be moved upwards to first compress air present in said second chamber and thereafter allow said valve to connect between said first and second chambers for infusion of liquid from said reservoir into said vessel and means for retaining said inner wall cylindrical member in a higher position than said position allowing said valve to connect between said first and second chambers.
A method for infusing a liquid from a liquid reservoir into a vessel, said vessel being located below said liquid reservoir, using a nozzle apparatus comprising an outer wall cylindrical member secured to the bottom of said reservoir and adapted to be filled with a liquid held in said reservoir, an inner wall cylindrical member fitted in said outer wall cylindrical member for axial movement therein, valve means in one of said inner and said outer wall cylindrical members and adapted to connect and disconnect between said inner and said outer wall members, and air-relief conduit means rigidly carried by said outer wall cylindrical member and extending through said outer wall cylindrical member, said valve means and said inner wall member, said method comprising charging a liquid into a reservoir with said valve means positioned to disconnect between said inner and said outer wall cylindrical members to allow said liquid to enter said outer wall cylindrical member, and elevating a vessel toward said nozzle apparatus to move upwards said inner wall cylindrical member to increase an air pressure in said inner wall cylindrical member until said inner wall cylindrical member reaches a position allowing said valve member to connect between said inner and said outer wall cylindrical members, whereby said liquid is gushed into said inner wall cylindrical member.
