Abstract
Abstract A water cooler comprising a support base having a top wall with a top opening therein. A refrigerating coil is located inside the base and supported a predetermined distance from the top opening. A one-piece removable well having a liquid retaining reservoir and a support flange wall, is removable supported on the top wall of the support base with the support flange in support contact on the top wall and the reservoir extending through the top opening with a lower portion of the reservoir disposed internally of the refrigerating coil and in close fit therewith. The reservoir has an upper portion with separating means being provided for separating the lower and upper portions and permitting liquid flow therebetween. The support flange is provided with a support wall disposed about the reservoir for supporting a liquid container having a bottle neck. The container is supported in an inverted position with the bottle neck extending into the upper portion of the reservoir above the separating means. The container support wall permits air flow between the reservoir upper portion and atmosphere and about the container.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
186 words
A water cooler comprising a support base having a top wall with a top opening therein, a refrigerating coil inside said base and supported a predetermined distance from said top opening, a one-piece removable well having a liquid retaining reservoir and a support flange wall, said removable well being removably supported on said top wall with said support flange in support contact on said top wall and said reservoir extending into said top opening with a lower portion of said reservoir disposed internally of said refrigerating coil in close fit therewith, said reservoir having an upper portion, separation means for separating said lower and upper portions to define a lower and upper chamber and permitting liquid flow therebetween, said support flange having support means about said reservoir for supporting a liquid container having a bottle neck in an inverted position with said bottle neck extending into said upper chamber of said reservoir spaced above said separation means, said support means permitting air flow between said reservoir upper and outside air and about said container, and dispensing means connected to said removable well for dispensing liquid therefrom.
Claim 2
Dependent Claim
186 words
A water cooler comprising a support base having a top wall with a top opening therein, a refrigerating coil inside said base and supported a predetermined distance from said top opening, a one-piece removable well having a liquid retaining reservoir and a support flange wall, said removable well being removably supported on said top wall with said support flange in support contact on said top wall and said reservoir extending into said top opening with a lower portion of said reservoir disposed internally of said refrigerating coil in close fit therewith, said reservoir having an upper portion, separation means for separating said lower and upper portions to define a lower and upper chamber and permitting liquid flow therebetween, said support flange having support means about said reservoir for supporting a liquid container having a bottle neck in an inverted position with said bottle neck extending into said upper chamber of said reservoir spaced above said separation means, said support means permitting air flow between said reservoir upper and outside air and about said container, and dispensing means connected to said removable well for dispensing liquid therefrom.
Claim 3
Dependent Claim
35 words
A water cooler as claimed in claim 1, wherein there is further provided a cover removably positionable over said top wall about said support flange for concealing said liquid container when on said support flange.
Claim 4
Dependent Claim
73 words
A water cooler as claimed in claim 1, wherein said separation means is a removable disc wall supported inside said reservoir by circumferential support means, a passage in said wall for the passage of a conduit for communicating a dispensing valve with the inner area of said reservoir upper chamber above said disc wall, and one or more orifices for permitting said liquid flow from said reservoir upper chamber to said lower chamber.
Claim 5
Dependent Claim
32 words
A water cooler as claimed in claim 3, wherein said reservoir is molded with a circumferential flange wall intermediate said upper and lower portion, said disc being supported by said flange wall.
Claim 6
Dependent Claim
79 words
A water cooler as claimed in claim 3, wherein said disc is a circular disc, said reservoir being a cylindrical reservoir, said disc having an outer diameter smaller than the diameter of said reservoir upper portion, and a plurality of spacer ribs formed about said disc for supporting said disc with said outer diameter edge spaced from a side wall of said upper chamber to permit liquid flow from said upper chamber to said lower chamber about said disc.
Claim 7
Dependent Claim
70 words
A water cooler as claimed in claim 1, wherein said reservoir is a cylindrical reservoir, said support means of said support flange being constituted by an inwardly inclined annular flange wall disposed about an open top end of said reservoir and molded therewith, and spacer means on an upper surface of said annular flange wall for supporting portions of said liquid container spaced from said inwardly inclined annular flange wall.
Claim 8
Dependent Claim
28 words
A water cooler as claimed in claim 6, wherein said spacer means are ribs disposed about said annular flange wall and aligned with diametrical axes of said reservoir.
Claim 9
Dependent Claim
63 words
A water cooler as claimed in claim 2, wherein said support flange wall is provided with a circumferential reinforcing rib which sits on said top wall of said support base, said support flange wall being configured to the cross-section of said support base and frictionally engaging a bottom contour edge of said cover which is of the same cross-section as said support base.
Claim 10
Dependent Claim
69 words
A water cooler as claimed in claim 3, wherein said support base is an elongated vertical housing provided with a liquid dispensing portion recessed in a side wall thereof, a pair of dispensing valves in said dispensing portion, a drip tray spaced below said valves and disposed in said housing, each valve having a conduit communicating with a respective one of said upper and lower chambers of said reservoir.
Claim 11
Dependent Claim
43 words
A water cooler as claimed in claim 9, wherein a thermal insulating open top end cylinder is supported in said support base below said top opening in said top wall, said refrigerating coil being disposed inside said cylinder adjacent a bottom wall thereof.
Claim 12
Dependent Claim
60 words
A water cooler as claimed in claim 1 wherein said dispensing means comprises two valves each having conduit means detachably connected to said removable wall, each conduig having an intake orifice associated with a respective one of said lower and upper chamber of said well, said liquid in said lower chamber being cooler than said liquid in said upper chamber.
