What is claimed is: 1. A liquid metered dispensing bottle, comprising: (a.) a squeezable container having an opening for dispensing liquid therefrom at one end and a bottom at the other end; (b.) a non-flexible trap chamber of a predetermined volume, connected to said opening of said container, said trap chamber having a lower end which is inserted into said container opening and having an inlet orifice extending from said lower end and into said container, said trap having an upper end with at least one dispensing orifice; (c.) a dip tube, said dip tube having an upper end extending from said inlet orifice and extending downwardly into said container, said dip tube having a lower end at or near the bottom of said container; (d.) a one way valve system connected to said lower end of said dip tube which permits liquid to flow from the container into said dip tube but not from said dip tube to said container, wherein said one way valve system includes: (i.) a valve housing with two opposing sidewalls and two inlet orifices, said two inlet orifices being a first inlet orifice being located on one of said two opposing sidewalls and a second inlet orifice being located on the other of said two opposing sidewalls, each of said two opposing sidewalls being non-vertical and non-horizontal on their insides, and (ii.) two slide valves, one being located at said first inlet orifice and the other being located at said second inlet orifice, each of said two slide valves having a rest position when said bottle is upright wherein both inlet orifices is closed, and having a second position when said bottle is inverted 180 degrees wherein both inlet orifices are open to air, and having a third position when said bottle is upright and squeezed wherein at least one of said inlet orifices are open to air and having a fourth position when said bottle is rotated 90 degrees from upright wherein one of said inlet orifices is open to air and the other of said orifices is closed; and, (e.) a brush connected to said trap chamber at its upper end and functionally connected to said at least one dispensing orifice. 2. The liquid metered dispensing bottle of claim 1 wherein said trap chamber has indicia which indicate predetermined volume levels. 3. The liquid metered dispensing bottle of claim 1 wherein said non-flexible trap chamber has either the male or female portion of a snap-in lock for permanent insertion into the opening of said container and said container has the other of the male or female portion of said snap-in lock. 4. The liquid metered dispensing bottle of claim 1 wherein said squeezable container contains a liquid for dispensing which fills the container to a predetermined level below said trap chamber to create an air space therebetween. 5. The liquid metered dispensing bottle of claim 1 wherein said dispensing orifice having a diameter small enough to prevent dripping of a liquid therefrom by gravity when inverted but being large enough to dispense liquid therefrom when said container is inverted and squeezed the exact diameter of the orifice being dictated by the viscosity of the liquid. 6. The liquid metered dispensing bottle of claim 1 wherein when said bottle is rotated 90 degrees, and said valves are in their fourth position, one of said inlet orifices is more elevated than the other of said inlet orifices, and wherein the more elevated inlet orifice is open to air and the other is closed. 7. The liquid metered dispensing bottle of claim 1 wherein said trap chamber has indicia which indicate predetermined volume levels. 8. The liquid metered dispensing bottle of claim 1 wherein said brush is selected from the group consisting of a separately created, attached brush and a brush integrally formed with said trap chamber. 9. The liquid metered dispensing bottle of claim 1 wherein said squeezable container contains a liquid for dispensing which fills the container to a predetermined level below said trap chamber to create an air space therebetween. 10. The liquid metered dispensing bottle of claim 1 wherein two slide valves are located on opposite ends of a single valve component. 11. The liquid metered dispensing bottle of claim 1 wherein said two trap slide valves are separate from one another and are each maintained in a slide track that permits movement along its sidewall and away from and toward its sidewall, and maintains functional orientation of said slide valve. 12. A liquid metered dispensing bottle, comprising: (a.) a squeezable container having an opening for dispensing liquid therefrom at one end and a bottom at the other end; (b.) a non-flexible trap chamber of a predetermined volume, connected to said opening of said container, said trap chamber having a lower end which is inserted into said container opening and having an inlet orifice extending from said lower end and into said container, said trap having an upper end with at least one dispensing orifice; (c.) a dip tube, said dip tube having an upper end extending from said inlet orifice and extending downwardly into said container, said dip tube having a lower end at or near the bottom of said container; (d.) a one way valve system connected to said lower end of said dip tube which permits liquid to flow from the container into said dip tube but not from said dip tube to said container, wherein said one way valve system includes: (i.) a generally inverted trapezoidal valve housing with tapered opposing sidewalls with an inlet orifice in each of said sidewalls, and (ii.) an inverted trapezoidal valve having opposing slide valve ends, and having a rest position when said bottle is upright wherein both inlet orifices are closed, and having a second position when said bottle is inverted 180 degrees wherein both inlet orifices are open to air, and having a third position when said bottle is upright and squeezed wherein at least one of said inlet orifices are open to air and having a fourth position when said bottle is rotated 90 degrees from upright wherein one of said inlet orifices is open to air and the other of said orifices is closed; and, (e.) a brush connected to said trap chamber at its upper end and functionally connected to said at least one dispensing orifice. 13. The liquid metered dispensing bottle of claim 12 wherein when said bottle is rotated 90 degrees, and said valve is in its fourth position, one of said inlet orifices is more elevated than the other of said inlet orifices, and wherein the more elevated inlet orifice is open to air and the other is closed. 14. The liquid metered dispensing bottle of claim 12 wherein said trap chamber has indicia which indicate predetermined volume levels. 15. The liquid metered dispensing bottle of claim 12 wherein said non-flexible trap chamber has either the male or female portion of a snap-in lock for permanent insertion into the opening of said container and said container has the other of the male or female portion of said snap-in lock. 16. The liquid metered dispensing bottle of claim 12 wherein said squeezable container contains a liquid for dispensing which fills the container to a predetermined level below said trap chamber to create an air space therebetween. 17. The liquid metered dispensing bottle of claim 12 wherein said inverted trapezoidal valve has a vertical central orifice at least partially aligned with said dip tube. 18. The liquid metered dispensing bottle of claim 12 wherein said valve housing has flat inside sidewalls at predetermined angles and said opposing slide valve ends are flat with corresponding predetermined angles.
