Holder for a liquid

1. A holder, for holding a liquid, the holder comprising:

(a) a supply chamber with a bottom surface, a peripheral wall standing from the peripheral edge of the bottom surface and a closing upper surface, wherein a passage opening is arranged close to or in the upper surface;

(b) a dosing chamber arranged on the passage opening of the supply chamber,

extending at least partly below the level of the passage opening, wherein the dosing chamber further comprises a pouring opening for pouring the liquid out of the dosing chamber; and

(c) a closure for closing either the pouring opening or the passage opening as desired, comprising a valve for closing the passage opening and a closing cap arranged on the pouring opening;

wherein the closing cap is coupled to the valve;

wherein the closure comprises a housing extending between the passage opening and the pouring opening, wherein the housing wall is perforated, and wherein the housing does not move within the holder during normal dosing and dispensing operations of the holder; and

wherein the closure further comprises a coupling for effecting a coupling between the closing cap and the valve during sealing of the pouring opening with the closing cap, wherein a coupling element is attached to the valve;

wherein the coupling comprises at least one finger extending from the coupling element and a cooperating groove within the closing cap, wherein the coupling may be disengaged such that the cap is not coupled to the valve;

wherein in a first position, the cap is secured in the pouring opening and the valve is depressed by the cap such that the passage opening is open and the at least one finger engages with the cooperating groove to couple the cap and valve so that the movement of the cap from the first position will cause the cap to pull the valve upward; and

wherein in a second position, the cap is removed from the pouring opening and the valve is positioned such that the passage opening is closed and the cap and valve are disengaged.

2. The holder as claimed in claim 1 , wherein the dosing chamber extends on the outer side of the supply chamber along at least a part of the peripheral wall.

3. The holder as claimed in claim 1 , wherein the dosing chamber is arranged eccentrically relative to the passage opening.

4. The holder as claimed in claim 1 , wherein the cap is a screw cap.

5. The holder as claimed in claim 1 , wherein the cap comprises a hingedly arranged cover.

6. The holder as claimed in claim 1 , wherein the fingers are resiliently engaged with the cooperating groove.
