Dispenser and methods
A chamber body is mounted to the bottle body and has an opening and partially bounds a first chamber and a second chamber. A selector is mounted to the chamber body for relative rotation between a first dosing condition and a second dosing condition. In the first dosing condition: flow is not blocked from the first chamber out the opening; flow is blocked from the second chamber out the opening; flow is blocked from the bottle interior to the first chamber; and flow is not blocked from the bottle interior to the second chamber. In the second dosing condition: flow is blocked from the first chamber out the opening; flow is not blocked from the second chamber out the opening; flow is not blocked from the bottle interior to the first chamber; and flow is blocked from the bottle interior to the second chamber.
1. An apparatus comprising:
a bottle body having an interior for storing a flowable material;
a chamber body mounted to the bottle body and partially bounding a first chamber and a second chamber and having:
an opening; and
a spout; and
a selector mounted for rotation relative to the chamber body between a first dosing condition and a second dosing condition,
wherein:
in the first dosing condition:
flow is not blocked from the first chamber out the opening;
flow is blocked from the second chamber out the opening;
flow is blocked from the bottle interior to the first chamber; and
flow is not blocked from the bottle interior to the second chamber; and
in the second dosing condition:
flow is blocked from the first chamber out the opening;
flow is not blocked from the second chamber out the opening;
flow is not blocked from the bottle interior to the first chamber; and
flow is blocked from the bottle interior to the second chamber.
2. The apparatus of claim 1 wherein:
the selector is mounted for rotation relative to the chamber body between said first dosing condition, said second dosing condition, and a free-pouring condition; and
in the free-pouring condition, flow is not blocked from the bottle interior, through the first and second chambers and out the opening.
3. The apparatus of claim 2 wherein:
the selector is mounted for rotation relative to the chamber body between said first dosing condition, said second dosing condition, a closed condition; and
in the closed condition, flow is blocked from the bottle interior into both the first and second chambers and is blocked from the first and second chambers out the opening.
4. The apparatus of claim 3 wherein:
the selector and chamber body combined to provide means for identifying each of the first dosing condition, second dosing condition, free-pouring condition, and closed condition.
5. The apparatus of claim 1 wherein:
the selector is mounted for rotation relative to the chamber body between said first dosing condition, said second dosing condition, a closed condition; and
in the closed condition, flow is blocked from the bottle interior into both the first and second chambers and is blocked from the first and second chambers out the opening.
6. The apparatus of claim 1 wherein:
a dose volume of the first chamber and of the second chamber is 15-75 ml.
7. The apparatus of claim 1 wherein:
a dose volume of the first chamber and of the second chamber is 20-40 ml.
8. The apparatus of claim 1 wherein:
the chamber body and selector are each a single separate piece assembled to each other.
9. The apparatus of claim 1 wherein:
the chamber body is threaded onto a neck of the bottle body.
10. The apparatus of claim 1 wherein:
the selector is held for rotation via a cooperating rib and channel.
11. The apparatus of claim 1 wherein:
the chamber body comprises vertical radial vanes between the inner wall, outer wall, and bottom wall, to define the first chamber and the second chamber.
12. The dispenser of claim 11 wherein:
the body is a single piece.
13. The apparatus of claim 1 wherein:
the bottle body is polyethylene; and
the chamber body and selector are polypropylene.
14. The apparatus of claim 1 wherein:
the chamber body comprises a two-piece assembly of a cup and a lid; and
the selector is a single separate piece assembled to the chamber body.
15. The apparatus of claim 1 further comprising:
a flowable material within the bottle body.
16. The apparatus of claim 1 wherein:
the bottle body interior has a volume of 0.4-2.0 l.
17. A method for using the apparatus of claim 1 comprising:
inclining the apparatus in the first dosing condition to pour a first dose of material from the first chamber and introduce a second dose of the material to the second chamber;
rotating the selector to the second dosing condition to isolate, relative to the bottle interior, the second chamber; and
inclining the bottle body in the second dosing condition to pour the second dose of material from the second chamber and replenish the first dose of the material in the first chamber.
18. The method of claim 17 further comprising:
rotating the selector to a free-pouring condition; and
in the free-pouring condition, inclining the bottle body to cause flow from the bottle interior, through the first and second chambers in parallel, and out the opening.
19. A method for manufacturing the apparatus of claim 1 , the method comprising:
securing the chamber body to the bottle body; and
securing the selector to the chamber body.
20. The method of claim 19 wherein:
the securing of the chamber body comprises locking to prevent rotation and extraction; and
the securing of the selector comprises snapping onto the chamber body to permit rotation between at least said first dosing condition and second dosing condition.
