The invention claimed is: 1. A coffee dosing apparatus comprising: a holder for coffee powder and a dosing mechanism, the dosing mechanism being provided with a dosing chamber bounded at a lower side by a bottom wall with a discharge opening and bounded at an upper side by an upper wall with a feed
The invention claimed is: 1. A coffee dosing apparatus comprising: a holder for coffee powder and a dosing mechanism, the dosing mechanism being provided with a dosing chamber bounded at a lower side by a bottom wall with a discharge opening and bounded at an upper side by an upper wall with a feed opening, the feed opening being rotationally staggered relative to the discharge opening, such that the upper wall extends above the discharge opening, a dosing element bounding portion spaces and being rotatable about a substantially vertically extending axis arranged in the dosing chamber, a driving element connected with the dosing element, wherein the driving element comprises a manually operable handle, a coupling provided between the handle and the dosing element such that the dosing element is rotatable in subsequent discrete steps, wherein at the end of a first discrete step a first of the portion spaces is located above the discharge opening, and a subsequent discrete step is startable only after the first discrete step has been rounded off completely, the coupling comprising a double ratchet mechanism. 2. A coffee dosing apparatus according to claim 1, wherein the double ratchet mechanism is provided with a ratchet wheel, a first ratchet spring and a second ratchet spring, the ratchet wheel is connected with the dosing element so as to be restrained from rotation, the first ratchet spring is connected with the handle, the second ratchet spring is firmly connected with the lower side of the bottom wall, the ratchet wheel is located at the lower side of the bottom wall. 3. A coffee dosing apparatus according to claim 1, wherein a loosening element is located above the upper wall of the dosing chamber and is connected with the dosing element so as to be restrained from rotation. 4. A coffee dosing apparatus according to claim 1, wherein the loosening element comprises a central hub with a number of arms radially extending from the hub. 5. A coffee apparatus according to claim 4, wherein the position of the arms is staggered relative to arms of the dosing element bounding the portion spaces. 6. A coffee dosing apparatus according to claim 1, wherein a wiper is connected with the dosing element so as to be restrained from rotation, wherein the wiper is arranged to wipe clean a transparent side wall of the holder. 7. A coffee dosing apparatus according to claim 1, wherein a coffee grinder is mountable on an upper side of the holder. 8. A coffee dosing apparatus according to claim 7, wherein an upper wall of the holder is provided with thread for mounting a closing cover and a connecting ring is provided with thread for fastening the coffee grinder on the holder.
