Abstract
A device is provided for controlled dispensing of a measured quantity of fluid from a flexible container. The device has a chamber adapted to hold a measured quantity of fluid when the container is inverted and righted. This fluid is then dispensed from the chamber through a conduit in direct response to a force exerted on the flexible wall of the container.
Claims8
A device for dispensing measured quantities of liquid from a supply of same comprising, in combination:
- a container having at least one flexible wall and a discharge opening;
- a measuring means adapted to fit said discharge opening, said measuring means having a chamber adapted for dispensing therefrom a liquid held therein;
- means for conducting said liquid between said contained and said chamber when the device is inverted and means for retaining in the chamber a variable measured said means for conducting comprising adjustable amount of said liquid when the device is returned to the upright position;
- means for discharging said liquid held in said chamber said means for discharging including conduit means extending from a location within the chamber and proximate its base to a point outside said device such that said liquid is discharged from said chamber in response to a force exerted on said flexible wall of said container;
- wherein said means for conducting said liquid between said container and said chamber when the device is inverted comprises a first tube portion and a second tube portion engaging sad first tube portion, said adjustable means comprising at least one opening formed in said first tube portion and at least one opening formed in said second tube portion such that said openings can be placed in alignment by rotating one of said tube portions, and movable means by which one of said tubes can be grasped and rotated.
