Abstract

The invention relates to a system for hygienically reconstituting and delivering food preparations, such as drinks, comprising a metering and mixing device connected to a container containing a base liquid, in the form of a package configured to be connected to a base station. The metering and mixing device comprises a pump for metering the liquid, a diluent intake and a mixing chamber. Coupling means are provided for providing the diluent supply and the means for driving the liquid pump.

First claim

The invention is claimed as follows:

1. A package for metering a liquid and mixing this liquid with a diluent to prepare a product, comprising:
a multi-dose container to form a reserve of liquid;
a metering and mixing device comprising:
a diluent inlet,
a liquid pump for metering the quantity of liquid,
a mixing chamber for mixing the liquid and the diluent,
a diluent coupling member and a member for driving the liquid pump which are configured to connect the metering and mixing device to a base station capable of providing a diluent supply to the diluent coupling member and capable of driving the member for driving the liquid pump,
wherein the metering and mixing device comprises two half-shells assembled with one another along a parting line and configured to delimit at least the contours of a chamber of the pump and the mixing chamber.

2. The package of claim 1 , wherein the two half-shells define, by their assembly, along their parting line, a liquid metering duct of the metering device for delivering the flow of diluted and mixed liquid directly to a receptacle, the liquid metering duct thus extending the mixing chamber.

3. The package of claim 2 , comprising a diluent duct that intersects the liquid metering duct, wherein the two half-shells define, along the parting line, the liquid metering duct and, at least partially, the diluent duct.

4. The package of claim 2 , wherein the diluent duct is positioned relatively to the liquid metering duct so that a stream of the diluent intersects a stream of the liquid before or at the mixing chamber.

5. The package of claim 4 , wherein the metering and mixing device comprises a means for increasing the speed at which the diluent arrives at a point where the streams meet, in the form of a restriction in communication with a diluent intake situated upstream of the mixing chamber so that the flow of diluent is accelerated through the restriction.

6. The package of claim 1 , wherein the metering and mixing device comprises an air intake before or in the mixing chamber to carry air into the mixture of the diluent and the liquid and cause the mixture to froth.

7. The package of claim 1 , wherein the liquid is selected from the group consisting of a food concentrate intended to be reconstituted, a hot drink, a cold drink, a frothy drink and a non-frothy drink.

8. The package of claim 1 , wherein the liquid is a soap, detergent or other similar product for the preparation of a non-food product.

9. A container cap for metering a base liquid and mixing the base liquid with a diluent to prepare a food product, the container cap being so constructed and arranged to be connected to a container containing the base liquid, and the container cap comprising:
a diluent inlet,
a liquid pump for metering the quantity of liquid,
a mixing chamber for mixing the liquid and the diluent,
a diluent intake and a coupling member for driving the liquid pump which are configured to connect the container cap to a base station capable of providing a diluent supply to the diluent intake and capable of driving the coupling member for driving the liquid pump, and
two half-shells assembled with one another along a parting line and configured to delimit at least the contours of a chamber of the liquid pump and the mixing chamber.

10. The container cap of claim 9 , with
the diluent intake being complementary to a diluent coupling member of the base station and
the coupling member for driving the liquid pump being complementary to a member for coupling the liquid pump of the base station,
the coupling member for driving the liquid pump being arranged to receive a drive shaft attached to the base station.

11. A package for docking to a base station and for metering a liquid and mixing this liquid with a diluent to prepare a product, the package comprising:
a multi-dose container to form a reserve of liquid;
a metering and mixing device comprising:
a diluent inlet,
a liquid pump for metering the quantity of liquid,
a mixing chamber for mixing the liquid and the diluent,
a plurality of coupling members each complementing a coupling member of the base station,
the coupling members of the package comprising a diluent intake and a coupling member for driving the liquid pump,
the diluent intake being complementary to a diluent coupling member of the base station and
the coupling member for driving the liquid pump being complementary to a member for coupling the liquid pump of the base station,
the coupling member for driving the liquid pump being arranged to receive a drive shaft attached to the base station,
wherein the metering and mixing device comprises two half-shells assembled with one another along a parting line and configured to delimit at least the contours of a chamber of the pump and the mixing chamber.
