Abstract

A removable leakproof stopper for use with liquid containing bottles which enables the user to quickly and easily dispense desired quantities of liquid and the method of use of the stopper. The stopper is a hollow chamber with a pour spout located at the top. A horizontal partition containing an exit port divides the chamber into two sections. The exit port is closed with a plug activated by a trigger which is located outside the chamber. Beneath the partition is a delivery tube attached about the interior circumference of the chamber. The delivery tube tapers downward to a constant bore portion which extends into the neck of the bottle. A compressible collar surrounding the constant bore portion provides a tight seal within necks of bottles of varying interior diameters. An opening in the wall of the chamber communicates with a pressure equalizing tube. A second trigger is used to close this opening. The triggers are oriented to permit both to be depressed simultaneously for good control and smooth delivery of liquid. There can be no leakage through the stopper if the bottle is tipped over or inverted and liquid can only be dispensed when both triggers are depressed simultaneously.
