Embodiment Construction

[0033] Figure 1a and 1b The figure shows the way in which a dose of powder is dispensed with a prior art dispenser. The dispenser comprises a tank 40 for storing powder and a metering device 41 . The metering means are present in the tube 42 in which a plate 43 (shown in dashed lines) is arranged in order to close or open the tube section. This plate 43 is fixed on a shaft 44 coupled to a manual actuator 45 . When the metering device is not working, the actuator is in Figure 1a The stationary state shown does have the plate 43 oriented horizontally. Thereby no powder is dosed. When it is desired to deliver a dose of powder, the actuator is turned clockwise through a 90° angle so that the plate is vertical and the powder can flow through the tube 42 . A stop member 46 is provided so that the actuator does not rotate more than 90°.

[0034] This allocator has some flaws:

[0035] - To dispense large quantities of powder, the operator using the dispenser must turn the a...

Abstract

The invention concerns a dosing unit for a powder dispenser comprising two dosing chambers (2,3) each chamber comprising: one upstream inlet (21, 31) and one downstream outlet (22, 32), an upstream means (23, 33) for opening and closing the inlet, a downstream means (24, 34) for opening and closing the outlet, the upstream means (23, 33) closing the inlet (21, 31) when the downstream means (24, 34) opens the outlet (22, 32) and reciprocally, wherein the upstream means (23) of the first chamber closes the first chamber (2) when the upstream means (33) of the second chamber opens the second chamber (3) and reciprocally.

Description

technical field [0001] The present invention relates to a dispenser for dispensing a predetermined amount of powder, preferably a beverage or food ingredient powder. Background technique [0002] Powder dispensers generally comprise a powder canister, the bottom of which is closed by a dosing device for dosing and filling a dose of powder into a container. For the simplest dispensers that are manually actuated, the metering device is usually a horizontal plate that plugs the bottom of the powder canister, which is rotated to become vertical and cause the powder to flow out of the canister. This rotation is performed by manually rotating the actuator along a 90° angle. Depending on the nature of the powder stored in the tank, specific instructions are set to obtain the correct dose of powder for preparing a beverage or food product from the powder ingredient. These commands correspond to the number of partial rotations that must be applied to the actuator. One rotation cor...
