Reservoir and method of making

A reservoir for use in a water distribution system within a refrigeration device comprising:

• a container having a vessel portion terminating at a neck around an opening,
• a cap sealingly engaging the container, the cap comprising:
• an internal surface in communication with an interior of the vessel portion,
• an external surface opposite the internal surface,
• an inlet aperture and an outlet aperture through the cap in fluid communication with the container opening,
• an inlet tube in fluid communication with the inlet aperture extending from the external surface,
• an outlet tube in fluid communication with the outlet aperture extending from the external surface,
• the reservoir being oriented in the upright position such that the cap is located above the vessel portion when the reservoir is installed in the refrigeration device,
• a dip tube in fluid communication with the outlet aperture extending from the internal surface into and near the bottom of the vessel,
• the cap further comprising a cylindrical outlet flange connecting the outlet tube and the dip tube, the outlet tube and the dip tube positioned within the cylindrical outlet flange, and
• an air vent from the interior of the vessel portion to the outlet tube, where the air vent comprises a groove in an inside surface of the cylindrical outlet flange in communication with the interior of the vessel portion extending along an outside surface of the dip tube adjacent to the outlet tube, and an opening in the outlet tube in communication with the groove,
• where a gap between the dip tube and the outlet tube allows air from the groove to pass between the dip tube and the outlet tube and enter the outlet tube.
