Abstract
A liquid dosage dispenser includes a bottle and a dispenser apparatus supported on the bottle having a housing or sleeve extending into the bottle and a plunger device having a through passageway extending into the housing for longitudinal movement therein. The housing includes an opening through which liquid in the bottle can be drawn into the housing. A helical channel and one or more vertical channels are provided in the housing. The plunger device is rotatable within the housing to permit a follower extending from the plunger device to ride in the helical channel to move the plunger longitudinally in the housing. As the plunger moves upwardly within the housing, a preselected amount of liquid is drawn into the housing. When the follower is positioned in a vertical channel associated with a desired dosage level, the plunger may be forced downwardly to deliver the desired dosage through the passageway and out of the dispenser. Indents are provided along the helical channel at various vertical channel positions. When the follower encounters an indent, it snaps into the indent to indicate that a preselected dosage of liquid is available to be dispensed.
