ABSTRACT:
An inverted liquid supply bottle containing liquid to be dispensed has a downwardly opening neck portion. In one form of the invention, a supply bottle support cup forms a reservoir defining a basin, an upper portion of which is nominally open to the atmosphere. The cup supports the bottle to position the bottom of the downwardly extending neck portion in spaced relation to the bottom of the cup. A liquid feed tube in the form of a capillary tube opens downwardly from the bottom of the reservoir basin and feeds into a transparent sight glass. A flexible deformable liquid delivery tube or hose carries the liquid being dispensed from the bottom of the sight glass to a location for use, and a manually operable hose clamp valve on the hose regulates the rate of flow of the liquid through the hose. In a second form, a reservoir providing a basin is situated below and spaced from the bottle neck. A liquid supply tube extends from inside of the bottle in sealing relationship to the neck portion and into the reservoir to terminate in the basin spaced from the bottom of the basin. A liquid delivery tube extends from the bottom of the basin into a conduit which delivers the liquid being dispensed to a location for use. In either form of the invention, the hose clamp on the outlet hose can be eliminated and flow can be controlled by controlling access of atmospheric pressure to the upper portion of the reservoir basin.
