Dosing dispenser system
View Patent ↗A dosing dispenser includes a housing, a traveler, and a plunger. The dosing dispenser also includes a driver. The housing defines a chamber, and the traveler and plunger are each positionable within the chamber. The traveler is configured to selectively position the plunger along an axis in at least one direction within the chamber.
1. A dosing dispenser comprising:
a housing defining a chamber;
a traveler 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; and
a plunger within the chamber,
wherein the traveler is movable along an axis between an engaged position and a disengaged position relative to the plunger within the chamber and when the dosing dispenser is assembled, and
wherein the traveler is spaced apart from the plunger in the disengaged position within the chamber and when the dosing dispenser is assembled.
2. The dosing dispenser of claim 1 , wherein the plunger comprises a first end and a second end, wherein the housing comprises a first end and a second end, wherein the second end of the plunger defines a plunger cavity, and wherein the plunger defines a filling portion of the chamber between the first end of the housing and the first end of the plunger.
3. The dosing dispenser of claim 1 , wherein the traveler is configured to abut and selectively position the plunger in the engaged position.
4. The dosing dispenser of claim 3 , wherein the traveler comprises a first end and a second end, wherein the first end comprises a plunger driver configured to selectively engage the plunger within a plunger cavity of the plunger and movably position the plunger within the chamber.
5. The dosing dispenser of claim 1 , further comprising a base assembly coupled to the housing, the base assembly comprising a base and configured to movably position the traveler within the chamber through rotation of the base.
6. The dosing dispenser of claim 1 , wherein in the disengaged position, the traveler is spaced apart from the plunger, and wherein in the engaged position, a plunger driver of the traveler abuts the plunger within a plunger cavity of the plunger.
7. The dosing dispenser of claim 1 , wherein the housing comprises a dispensing channel, wherein the plunger comprises a crown, wherein the plunger defines a filling portion of the chamber between the dispensing channel and the plunger, and wherein at least a portion of the crown is positionable within the dispensing channel of the housing when a volume of the filling portion of the chamber is at a minimum.
8. The dosing dispenser of claim 7 , wherein the housing further comprises an intermediate chamber between the chamber and the dispensing channel, and wherein at least a portion of the crown is positionable within the intermediate chamber when the volume of the filling portion of the chamber is at the minimum.
9. A dosing dispenser comprising:
a housing defining a chamber and comprising a first end and a second end, wherein the first end comprises a dispensing aperture;
a traveler movable within the chamber, wherein the traveler comprises a first end and a second end opposite from the first end, and wherein the first end and the second end are retained within the chamber such that the traveler is retained within the chamber when assembled; and
a plunger movable within the chamber,
wherein the traveler is configured to selectively position the plunger along an axis in at least one direction within the chamber.
10. The dosing dispenser of claim 9 , wherein the housing further comprises a dispensing channel in fluid communication with the chamber at the first end.
11. The dosing dispenser of claim 9 , wherein the housing further comprises a dispensing channel in fluid communication with the chamber, and wherein the at least one direction is towards the dispensing channel.
12. The dosing dispenser of claim 9 , wherein the traveler is configured to move independently from the plunger in a direction opposite from the at least one direction.
13. The dosing dispenser of claim 9 , further comprising a base assembly configured to movably position the traveler within the chamber.
14. The dosing dispenser of claim 13 , wherein the base assembly comprises:
a base;
a drive screw threadably engaged with the traveler and coupled to the base such that rotation of the base rotates the drive screw and axially moves the traveler within the chamber;
a base support rotatably supporting the drive screw and the base, the base support comprising a mounting portion and a supporting portion, the supporting portion comprising at least one notch; and
a cam mounted on the drive screw and comprising at least one extension configured to engage the at least one notch as the cam is rotated by the drive screw.
15. The dosing dispenser of claim 9 , wherein a cross-sectional shape of the plunger is substantially similar to a cross-sectional shape of the chamber such that the plunger forms a fluid tight seal with the housing within the chamber as the plunger is movably positioned within the chamber.
16. 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;
a driver at least within the chamber and engaged with the traveler such that rotation of the driver movably positions the traveler within the chamber; and
a plunger within the chamber and engaged with the traveler such that movement of the traveler movably positions the plunger along an axis in at least one direction within the chamber when the dosing dispenser is assembled.
17. The dosing dispenser of claim 16 , wherein the traveler is movable along the axis between an engaged position and a disengaged position relative to the plunger within the chamber and when the dosing dispenser is assembled, and wherein the traveler is spaced apart from the plunger in the disengaged position within the chamber and when the dosing dispenser is assembled.
18. The dosing dispenser of claim 16 , wherein the traveler is hollow and comprises a chamber extending from the first end to the second end of the traveler.
19. The dosing dispenser of claim 16 , wherein the traveler comprises threading such that the traveler is threadably engaged with the driver within the chamber.
20. The dosing dispenser of claim 16 , wherein the plunger comprises a first end and a second end, wherein the first end of the plunger is proximate to a first end of the housing relative to the second end of the plunger, wherein the second end of the plunger defines a plunger cavity, and wherein the first end of the traveler is configured to engage the plunger within the plunger cavity.
