Abstract

The invention relates to a device for extracting a cap comprising a first part, a second part which is movable with respect to the second part which is provided with a space for the cap and defines the cap extracting position in a closed position thereof, an introduction and positioning part comprising the cap guiding elements which are arranged in such a way that it is possible to insert it in an intermediate position and a beverage pouring system in which the second movable part displaces the cap from the intermediate position to the extraction position.

Claims

1. A device for extraction of a capsule, the device comprising:

a first part;

a second part which is mobile relative to the first part;

a receptacle for the capsule, which, in a first position of closure of the second, mobile part against the first part, defines a position of extraction of the capsule according to an axis in the receptacle;

a part for introduction and positioning, comprising guide means for guiding the capsule, which are arranged to insert the capsule by gravity, and to position the capsule in an intermediate position; and

a system for flow of a drink, the second, mobile part being configured to displace the capsule from the intermediate position to the position of extraction during closure of the device,

the system for flow of a drink comprises stop means, the stop means comprise a first stop member and a second stop member, the guide means comprise a first guide member on which the first stop member is positioned and a second guide member on which the second stop member is positioned, and the first and second guide members are opposed elements pivotable independently, the second, mobile part acting on an opening of the stop means to move the stop means apart from each other during passage of the capsule from the intermediate position to the position of extraction.

2. The device according to claim 1, wherein the stop means are configured to retain the capsule in the intermediate position according to an axis which is substantially coaxial to the axis of the receptacle.

3. The device according to claim 1, wherein the first part is fixed and comprises a substantially horizontal guide body that guides the second, mobile part in translation towards the first, fixed part.

4. The device according to claim 3, wherein the part for introduction and positioning of the capsule is arranged in front of the guide body and comprises the first and second guide members.

5. The device according to claim 4, wherein the stop means are arranged to block the capsule in the intermediate position when the second, mobile part is in an opening position, permitting insertion of a capsule, and to release the capsule when the second, mobile part is in the closure position, to allow the capsule to be displaced from the intermediate position to the position of extraction, and to allow the capsule to be released when the second, mobile part is reopened.

6. The device according to claim 1, comprising an extraction plate towards which the second, mobile part displaces the capsule in the position of extraction.

7. The device according to claim 1, wherein the second, mobile part is moved by means which assure displacement into the opening and closure positions.

8. The device according to claim 7, wherein the means which assure the displacement are a system of connecting rods.

9. The device according to claim 1, wherein reopening of the second, mobile part permits dropping of the capsule by gravity.

10. The device according to claim 9, wherein the capsule is guided in its fall by the guide means.

11. A coffee machine comprising:

a device for extraction of a capsule, the device comprising;

a first part;

a second part which is mobile relative to the first part;

a receptacle for the capsule, which, in a first position of closure of the second, mobile part against the first part, defines a position of extraction of the capsule according to an axis in the receptacle;

a part for introduction and positioning, comprising guide means for guiding the capsule, which are arranged such as to insert the capsule by gravity, and to position the capsule in an intermediate position; and

a system for flow of a drink, the second, mobile part being configured to displace the capsule from the intermediate position to the position of extraction during closure of the device, the system for flow of a drink comprises stop means, the stop means comprise a first stop member and a second stop member, the guide means comprise a first guide member on which the first stop member is positioned and a second guide member on which the second stop member is positioned, and the first and second guide members are opposed elements pivotable independently, the second, mobile part acting on an opening of the stop means in order to move the stop means apart from each other during passage of the capsule from the intermediate position to the position of extraction;

a water reservoir;

a water duct;

a pump for displacement of the water;

means for heating the water; and

a water intake in the second, mobile part of the device.

12. A system comprising:

a device for extraction of a capsule, the device comprising;

a first part;

a second part which is mobile relative to the first part;

a receptacle for the capsule, which, in a first position of closure of the second, mobile part against the first part, defines a position of extraction of the capsule according to an axis in the receptacle;

a part for introduction and positioning, comprising guide means for guiding the capsule, which are arranged such as to insert the capsule by gravity, and to position the capsule in an intermediate position; and

a system for flow of a drink, the second, mobile part being configured to displace the capsule from the intermediate position to the position of extraction during closure of the device, the system for flow of a drink comprises stop means, the stop means comprise a first stop member and a second stop member, the guide means comprise a first guide member on which the first stop member is positioned and a second guide member on which the second stop member is positioned, and the first and second guide members are opposed elements pivotable independently, the second, mobile part acting on an opening of the stop means in order to move the stop means apart from each other during passage of the capsule from the intermediate position to the position of extraction; and

an asymmetrical capsule comprising a guide edge which is controlled by guide means of the device.

13. The system according to claim 12, wherein the capsule contains roasted ground coffee.

14. A device for extraction of a capsule, the device comprising:

a first part;

a second part which is mobile relative to the first part;

a receptacle for the capsule, which, in a first position of closure of the second, mobile part against the first part, defines a position of extraction of the capsule according to an axis in the receptacle;

a part for introduction and positioning, comprising a plurality of guide members for guiding the capsule, which are arranged to insert the capsule by gravity, and to position the capsule in an intermediate position; and

a system for flow of a drink, the second, mobile part being configured to displace the capsule from the intermediate position to the position of extraction during closure of the device, the system for flow of a drink comprises stop members, the stop members comprise a first stop member and a second stop member, the plurality of guide members comprise a first guide member on which the first stop member is positioned and a second guide member on which the second stop member is positioned, and the first and second guide members are opposed elements pivotable independently, the second, mobile part acting on an opening of the stop members to move the stop members apart from each other during passage of the capsule from the intermediate position to the position of extraction.
