Portable liquid dispenser
First Claim
1. A person-carried or vehicle-carried portable liquid dispenser comprising;
- a liquid container having a filling cap for receiving liquids,a single flexible dispensing tube having two separate, longitudinally-extending, substantially parallel passages extending from end to end thereof,said tube having one end attached to and opening into said filling cap and its other end extending therefrom,a dispensing valve attached to the extended end of said dispensing tube for selectively dispensing liquid from said container,pressurizing means secured on said dispensing tube in communication with one of said longitudinal passages for creating air pressure within said container, andthe other of said longitudinal passages interconnecting said dispensing valve and the interior of said container whereby operation of said dispensing valve permits flow of liquid from said container through said other longitudinal passage.

Abstract
A portable liquid dispenser suitable for use by persons while performing an activity comprises a thermally-insulated container for liquids having a fastener for releasably attaching the same for access by the user. A single flexible dispensing tube having a pair of parallel longitudinal passages is connected at one end connected to the filling cap of the container and at the other end to a dispensing valve for discharging liquids from the container. The container is pressurized by a compressible bulb sealed end around the distal end of the dispensing tube in communication with the interior of the container through one longitudinal passage in the tube. A check valve is disposed in the air inlet of the fitting and another check valve is disposed in the air inlet of the dispensing valve which cooperate with the bulb to force air into the container. A number of compressions of the bulb forces air into the container to pressurize the liquid therein which flows through the other longitudinal passage on demand of the user by pressing a plunger on the dispensing valve.

29. A person-carried or vehicle-carried portable liquid dispenser comprising;
-
a liquid container having a filling cap for receiving liquids, tube means having two separate, longitudinally-extending, passageways, extending in closely spaced parallel relation for substantially their entire length, said tube means having one end attached to and opening into said filling cap and its other end extending therefrom, a dispensing valve attached to the extended end of said tube means in communication with only one of said passageways for selectively dispensing liquid from said container, pressurizing means secured on said tube means surrounding both of said passageways but in communication with only the other one of said passageways for creating air pressure within said container, and said one passageway interconnecting said dispensing valve and the interior of said container whereby operation of said dispensing valve permits flow of liquid from said container through said one passageway and out of said valve.
