Abstract
A dosing dispenser for a flowable composition includes a housing, a traveler, a plunger, and a driver. The housing defines a chamber, and the plunger is movable within the chamber. The traveler is at least partially within the chamber and configured to selectively position the plunger. The driver is at least partially within the chamber and configured to movably position the traveler relative to the driver. The driver is engaged with the traveler within the chamber.
Claims12
A dosing dispenser comprising:
- a housing defining a chamber;
- a traveler comprising a first end and a second end opposite from the first end, wherein the traveler is retained within the chamber when the dosing dispenser is assembled such that the first end and the second end are within the chamber;
- an anti-back rotation assembly comprising an elongated driver and at least one flexible arm rotatable with the elongated driver, wherein the anti-back rotation assembly is at least partially within the chamber and engaged with the traveler such that rotation of the driver movably positions the traveler within the chamber along an axis,
- wherein the at least one flexible arm extends circumferentially in a direction opposite a direction of rotation of the driver, wherein the at least one flexible arm comprises an outer surface facing outwards and an inner surface facing inwards, and wherein, when the dosing dispenser is assembled, the outer surface of the at least one flexible arm is an outermost extent of the anti-back rotation assembly;
- a base that is rotatable relative to the housing, and wherein the rotation of the driver is caused by rotation of the base;
- and
- a plunger within the chamber and engageable with the traveler,
- wherein, when the dosing dispenser is assembled and the traveler is engaged with the plunger, the plunger is unidirectionally movable by the traveler within the chamber along the axis, and
- wherein the traveler is configured to selectively position the plunger at a predetermined location by unidirectionally moving the plunger along the axis so as to dispense a predetermined quantity of a flowable composition from the dosing dispenser.
A dosing dispenser comprising:
- a housing defining a chamber and comprising a first dispensing end, a second end, and a sidewall extending from the first dispensing end to the second end;
- a traveler comprising a first end and a second end opposite from the first end, wherein the traveler is retained within the chamber when the dosing dispenser is assembled such that the first end and the second end are within the chamber;
- a driver at least partially within the chamber and engaged with the traveler such that rotation of the driver movably positions the traveler within the chamber along an axis;
- and
- a plunger engageable with the traveler and movable within the chamber between a dispensed position and a filled position, wherein, in the filled position, the plunger is at a maximum spaced apart distance from the first dispensing end of the housing, and wherein, in the dispensed position, the plunger is at a minimum distance from the first dispensing end,
- wherein, when the dosing dispenser is assembled and the traveler is engaged with the plunger, in the dispensed position, at least a portion of the driver is uncovered within the chamber relative to the sidewall of the housing.
