A stable upright fluid dispensing container in which a fluid is dispensed from the top of the container while the container remains in an upright position. The bulk of the fluid always remains in the bottom of the container. A passageway tube and a plunger apply pressure on the fluid. Knobs on the plunger can include horizontal knob gears, vertical knob gears or push button rack gears. Pressure can also be applied to the fluid by a non-rotating threaded passageway tube having a fixed plunger and a rotating threaded knob. In flexible sealed containers pressure can be applied to the fluid by providing a flexible sealed container, a non-threaded passageway tube and one-way check valve. These features provide increased pressure such that the fluid will be forced to flow into a passageway tube through an entrance opening at the bottom of the passageway tube, up through the tube and out an exit opening. Further, once pressure is relaxed, the fluid flow will stop and the fluid will remain in the passageway tube. Thus, all the fluid in the container will be dispensed.

1. Field of the Invention
A new mechanism that dispenses fluids, especially highly viscous fluids, from a container, particularly upright containers, in an efficient and user friendly manner is disclosed. More particularly, the present invention provides fluid dispensing containers such that fluid is dispensed from the top of the containers while the bulk of the fluid always remains at the bottom of the container. This provides a container that is stable in an upright position and a container such that all the fluid contained therein is easily dispensed without problem.
2. Description of the Art
FIG. 1. is a flow chart of the various embodiments of the stable upright fluid dispensing container according to the present invention.
FIGS. 2A-2C are illustrations of various views of the rotating threaded passageway tube and free non-rotating threaded plunger according to an embodiment of the stable upright fluid dispensing of the present invention;
FIGS. 3A-3C are illustrations of a non-rotating threaded passageway tube having a plunger fixed to a passageway tube and a free rotating threaded knob according to another embodiment of the stable upright fluid dispensing container of the present invention;
The following new containers have been invented in order to dispense fluids, especially high viscous fluids, from a container, especially an upright container, in an efficient and user-friendly manner. The uniqueness of these containers is that the fluid within the containers can be dispensed from the top of the containers while the bulk of the liquid always remains on the bottom of the container thereby making the containers stable in the upright position and able to dispense all the fluid therein.
The new containers eliminate the need to turn the container upside down in order for the fluid to flow to the top of the container when the fluid is almost all used. Instead, the container is always in the upright position, the user squeezes it, turns, or pushes a knob, and the fluid therein is dispensed. In the containers of the present invention, the liquid always remains on the bottom of the container making the container stable in the upright position. This improves the efficiency and ease at which the liquid is dispensed.
The containers of the present invention are designed to dispense a wide variety of fluids such as shampoo and other hair products, body lotions, and food products such as mustard, ketchup, and mayonnaise. The containers of the present invention are also able to dispense fluids in a controlled manner so that a required amount of fluid can be dispensed and recorded, such as in the recommended dose of fluoride toothpaste in the tooth care of children. In this case, even when it is recommended by professionals (Ad Hoc Subcommittee on Fluoride (1991) “Public Health Service Report on Fluoride Benefits and Risks” pg 6) to provide a regulating dose dispenser for fluoride toothpaste used by children, no such container is available at this time. The container of the present invention fulfills the requirements of fluoride treatments recommended by this report.
