Abstract

The invention is directed to a dispenser attachment to be mounted on a standard bottle having exterior threads at its neck. The attachment has two side arms emanating from a center. One arms has at its outer end a pressuring air bulb attached thereto. The outer end of the bulb has a one-way ball valve attached therein and another one-way ball valve is attached within the other end of the bulb. The pressurized air generated by the bulb enters directly into the interior of the bottle by way of a passage way. The passage way has a bypass just downstream of said one-way ball valve to accommodate the inward movement of the ball. The pressurized fluid in the bottle is controlled by a single unit ball valve assembly having a push button under a bias of a spring. The push button is located at the top of the attachment and is flush with its surface.
