ABSTRACT:
A disposable oral liquid measure/dispenser for administering measured, pre-packaged dosages of liquid medication or food to human or animal patients comprises a one-piece structure made of a flexible thermoplastic, preferably by blow-molding. The container/dispenser has an upper cylindrical neck section for filling with liquid and sealable with a tamper-evident seal. A flexible bellows section extending downwards from the neck section joins a central fluid reservoir section, which is in turn joined at its lower end to a dispensing tube shaped like an inverted U-tube. The outer, outlet leg of the dispensing tube has a cap which is serverable by a scissors when it is desired to dispense the contents. Pushing downward on the upper surface of the sealing cap collapses the bellows, pressurizing the fluid storage reservoir section of the container. This in turn forces fluid upwards into the inner, inlet leg of the dispenser tube, and out the outlet leg into a patient's mouth.
