Liquid container support and probe-type hygienic liquid dispensing system

A liquid container support and hygienic delivery system for dispensing drinking water or other potable liquid to a predetermined maximum liquid level in a dischargeable reservoir open at its upper end and housed within a cabinet from an inverted unpressurized container having an internal liquid confining surface defined by a substantially rigid, generally cylindrical body with a radially inwardly directed downwardly sloping shoulder portion merging into a generally cylindrical depending neck defining an opening closed by a coaxial cap circumferentially surrounding at least an outer axial portion of said neck and having an internal recess therein including a hollow tubular sleeve portion and a plug and recess sealing portion connected thereto and defining a closed end with a central cavity having internal gripping means therein comprising, in combination,

• removable mounting means adapted to fit on the upper portion of said cabinet and defining an annular ring for supporting said sloping shoulder portion of said inverted container thereon, said removable mounting means also defining a tapered entry portion having a substantially closed inner wall extending downwardly and inwardly from said annular ring for receiving said depending container neck and said coaxial cap therein, said entry portion having a substantially closed bottom end and a length greater than that of said depending container neck and said coaxial cap when said inverted container shoulder portion is supported on said annular ring,
• sealing means carried by said removable mounting means for sealingly closing said open upper end of said reservoir,
• an upstanding feed probe dimensioned to penetrate into said hollow tubular sleeve portion of said coaxial cap and said container neck to provide a hygienic flow path for delivering liquid from said inverted unpressurized container into said reservoir to said predetermined maximum liquid level and for admitting air from said reservoir above said liquid level into said container to displace the liquid delivered therefrom, said feed probe having upper and lower end portions,
• means carried by said removable mounting means for rigidly supporting said upstanding feed probe with said upper end projecting upwardly from said bottom end of said entry portion and means depending downwardly from said bottom end of said entry portion of said removable mounting means into said reservoir to define said predetermined maximum liquid level,
• said upper end of said feed probe having a length greater than said recess in said coaxial cap and a tip portion disposed and dimensioned for entry into said recess to axially separate said cap plug and recess sealing portion from said hollow tubular sleeve portion when said container is inverted and lowered onto said mounting means with said sloping shoulder portion of said inverted container supported by said annular ring in order to permit the discharge of liquid from said container into said reservoir to said predetermined maximum liquid level and admission of air from said reservoir above said liquid and into said container,
• said tip portion of said upstanding feed probe being formed with complementary external gripping means disposed and dimensioned for securing said plug and recess sealing portion on said feed probe and for holding said plug and recess sealing portion free of contact with said internal liquid confining surface of said inverted container when said feed probe is inserted in said recess of said coaxial cap to axially separate said plug and recess sealing portion from said hollow tubular sleeve portion when said sloping shoulder portion of said inverted container is supported on said annular ring of said mounting means,
• and said upstanding feed probe being dimensioned and disposed to draw said plug and recess sealing portion into interfitting sealing relation with said hollow tubular sleeve portion when said inverted container is lifted off said support ring and said feed probe is withdrawn from said recess of said coaxial cap.
