10. A lid according to claim 1 and further comprising a dispensing spout having a first end in communication with said dispensing opening and a second end facing in a downward direction when said lid is in said open position, said dispensing spout having a longitudinal tube axis, said second end of said spout being surrounded by an end edge of said spout which lies in a plane oblique to said longitudinal axis of said spout.

11. A lid according to claim 1 wherein said housing is detachably mounted to said lid for selective removal of said housing from said lid.

12. A lid according to claim 1 and further comprising a counterbalance assembly mounted to said lid for yieldably urging said lid toward said open position about said hinge.

13. A lid according to claim 12 wherein said counterbalance assembly comprises a torsion spring.

14. A lid according to claim 12 wherein said counterbalance assembly is detachably mounted to said lid.

15. The lid according to claim 1 wherein the valve is spring biased toward the closed position.

16. A lid for a washing machine having an upwardly presented access opening, comprising:

a lid frame having a front edge, a rear edge, side edges, an upper surface, and a lower surface;

a hinge connected to one of said lid frame edges permitting hinged attachment of said lid frame to said washing machine for pivotal movement between an open position wherein said upper and lower surfaces are upstanding and a closed position;

a housing carried on said lower surface of said lid frame and forming a dispensing chamber;

said housing having a fill opening providing communication into said dispensing chamber for filling said chamber with a fluid;

said housing having a dispensing opening forming communication from within to outside said dispensing chamber for permitting removal of said fluid from said dispensing chamber;

a manually operated dispensing valve mounted in said dispensing opening and manually movable from a normally closed position preventing fluid from leaving said chamber through said dispensing opening to an open position permitting fluid to exit through said dispensing opening when said lid frame is in said open position;

an indicator on said housing for visually representing the amount of fluid which has been dispensed from said dispensing chamber; and

said dispensing opening being located above said access opening when said lid frame is in said open position whereby fluid exiting from said dispensing opening will fall by gravity into said access opening.

17. A lid according to claim 16 wherein said indicator further comprises a window in said housing permitting visual inspection of the level of fluid within said dispensing chamber.

18. A lid according to claim 17 and further comprising a marker attached to said window and movable to a plurality of positions with respect to said window to mark the level of said fluid within said dispensing chamber after a predetermined amount of said fluid has been dispensed.

19. A lid according to claim 17 wherein said housing includes a slide track formed adjacent said window, said marker being mounted within said slide track for sliding movement therein.

20. The lid according to claim 16 wherein the valve is spring biased toward the closed position.

21. A lid for a washing machine having an upwardly presented access opening, comprising:

a lid frame having a front edge, a rear edge, side edges, an upper surface, and a lower surface;

a hinge connecting the lid frame to the washing machine for movement between open and closed positions relative to the access opening;

a housing carried on said lower surface of said lid frame and forming a dispensing chamber;

said housing having a fill opening providing communication into said dispensing chamber for filling said chamber with a fluid;

said housing having a dispensing opening forming communication from within to outside said dispensing chamber for permitting dispensing of said fluid from said dispensing chamber;

a manually operated dispensing valve mounted in said dispensing opening and manually movable from a normally closed position preventing fluid from leaving said chamber through said dispensing opening to an open position permitting fluid to exit through said dispensing opening when said lid frame is in said open position;

said dispensing valve being detachably mounted in said dispensing opening and selectively removable therefrom for cleaning; and

said dispensing opening being located above said access opening when said lid frame is in said open position whereby fluid exiting from said dispensing opening will fall by gravity into said access opening.
