Abstract

A portable liquid dispenser for dispensing one of two liquids from a single vessel has a base with first and second separate horizontally disposed compartments separated by a liquid-impermeable barrier, a neck secured to the base and mounting handle, a valve assembly including first and second valve elements rotatably mounted in the neck for swinging between open and blocking relationship with the compartments and a valve seat in snap-fit relationship with the valve assembly. The valve elements swing downwardly for alternate abutment with the impermeable barrier and into sealing engagement with the valve seat. An actuator is coupled to the valve elements through a shaft and is positioned for actuation by the thumb of a user which grips the handle. The base can be formed in separate injection-molded sections which are secured together and which have a stainless steel bottom integrally molded into the bottom of the section.

Claims

1. A hand-held, portable liquid dispenser for selectively dispensing one of two different liquids from a single container, said dispenser comprising:

a base forming first and second separate horizontally disposed compartments separated by a liquid-impermeable barrier;

a neck secured to said base, mounting a handle at one side and forming a spout on an opposite side thereof, said neck having a central opening through which liquid may be introduced into the base and dispensed from the base;

valve means mounted in said neck and having a sleeve forming valve seats at a bottom portion thereof and first and second valve elements rotatable in unison in said neck between first and second positions, said first valve element is in seating contact with one of said seats, blocking communication between said first compartment and said spout, when in said first position and is adjacent said barrier, opening communication between said first compartment and said spout, when in said second position, said second valve element is adjacent said barrier, opening communication between said second compartment and said spout when in said first position and is in sealing contact with the other of said seats, blocking communication between said second compartment and said spount, when in said second position;

said liquid-impermeable barrier comprising a wall which extends up to said valve seats; and

actuator means coupled to said valve means for moving said valve elements between said first and second positions and mounted on said neck in close proximity to said handle so that said actuator means can be operated by the thumb of a user whose hand grips the dispenser by the handle.

2. A liquid dispenser according to claim 1 wherein said valve means sleeve is circular;

and said valve elements are semicircular in shape.

3. A liquid dispenser according to claim 2 wherein said valve elements have an included angle of about 60°

therebetween.

4. A liquid dispenser according to claim 2 and further comprising means for rotatably mounting said valve elements in said sleeve.

5. A liquid dispenser according to claim 4 wherein said sleeve is mounted in snap-fit engagement in said neck.

6. A liquid dispenser according to claim 5 wherein said valve elements and actuator are mounted in snap-fit engagement in said sleeve.

7. A liquid dispenser according to claim 6 wherein said sleeve is formed of a relatively soft material to form pliant seats.

8. A liquid dispenser according to claim 7 wherein said neck is permanently secured to an upper portion of said base.

9. A liquid dispenser according to claim 8 wherein said base is at least partially molded from a plastic material with said liquid-impermeable barrier.

10. A liquid dispenser according to claim 9 wherein said base further comprises a metal bottom plate integrally molded to said molded plastic material.

11. A liquid dispenser according to claim 2 wherein said sleeve is mounted in snap-fit engagement in said neck.

12. A liquid dispenser according to claim 11 wherein said valve elements and said actuator are mounted in snap-fit engagement in said sleeve.

13. A liquid dispenser according to claim 1 wherein said base is at least partially molded from a plastic material with said liquid-impermeable barrier.

14. A liquid dispenser according to claim 13 wherein said base further comprises a metal bottom plate integrally molded to said molded plastic material.

15. In a liquid dispenser having an open-top base for holding liquid and an annular neck secured to said base, said neck forming a spout on one side and a handle on another side thereof, the neck having a central opening through which liquid may be introduced into the base and dispensed from the base;

the improvement which comprises;

a liquid-impermeable barrier dividing said base into two separate horizontally disposed compartments;

valve means mounted in said neck and comprising valve seats disposed in said central opening and valve elements mounted in abutting relationship with said barrier and adapted to alternately seat against said valve seats to close off one of said two compartments, while opening the other, and vice versa, said valve means further comprising means to rotatably mount said valve elements in said neck for rotational movement to swing downwardly into said base between said seats and said barrier; and

actuator means coupled to said valve elements to rotate said valve elements between said two alternate positions.

16. A liquid dispenser according to claim 15 wherein said barrier extends to said valve seats and forms a pair of semicircular openings therewith;

and said valve elements have a semicircular shape to conform with said semicircular openings.

17. A liquid dispenser according to claim 16 wherein the included angle between said valve elements is about 60°

.

18. A liquid dispenser according to claim 16 wherein said valve seat is formed in an annular sleeve of a relatively soft material.

19. A liquid dispenser according to claim 18 wherein said valve elements are snap-fit into said annular sleeve.

20. A liquid dispenser according to claim 19 wherein said annular sleeve is snap-fit into said neck.

21. A liquid dispenser according to claim 20 wherein said actuator is mounted in close proximity to said handle so that one can operate said actuator with the thumb of a hand which grips said handle.

22. A liquid dispenser according to claim 16 wherein said base is at least partially molded from a plastic material and has a metal bottom plate integrally molded therewith.

23. A hand-held, portable liquid dispenser for selectively dispensing one of two different liquids from a single container, said dispenser comprising:

a base forming first and second separate horizontally disposed compartments separated by a liquid-impermeable barrier, said base having a metal bottom portion and a molded plastic upper portion forming said barrier, said metal base being integrally molded to said plastic upper portion;

a neck secured to said base, mounting a handle at one side and forming a spout on an opposite side thereof, said neck having a central opening through which liquid may be introduced into the base and dispensed from the base;

valve means mounted in said neck and having first and second valve elements rotatable in unison in said neck between first and second positions, said first valve element blocking communication between said first compartment and said spout when in said first position and opening communication between said first compartment and said spout when in said second position, said second valve element opening communication between said second compartment and said spout when in said first position and blocking communication between second compartment and said spout when in said second position; and

actuator means coupled to said valve means for moving said valve elements between said first and second positions and mounted on said neck in close proximity to said handle so that said actuator means can be operated by the thumb of a user whose hand grips the dispenser by the handle.

24. A liquid dispenser according to claim 23 wherein said barrier extends to and is in sealing engagement with said metal bottom portion and extends upwardly therefrom to and in sealing engagement with said valve means.
