ABSTRACT:
The discharge spout of an inverted container of liquid product to be dispensed is received in a sleeve, the upper end of which is threaded onto the container in outwardly spaced relation from the spout. A metering and sealing cup supported within the sleeve receives the spout, the arrangement being such that the sleeve may be rotated about its threaded connection to the container, either to bring the cup into sealing relation with the container spout or into dispensing relation with respect thereto. The cup normally maintains a supply of liquid above the level of the discharge opening of the spout lower end and, under proper pressure conditions, permits overflow of product through a discharge passage which establishes communication between the cup and the open lower end of the sleeve. The discharge is automatically controlled by alternate compression and decompression of air within the sleeve arising from rising and falling of the column of tank water therein, as the flush tank is flushed and refilled.
