Abstract

A beverage dispensing apparatus for extracting beverage from a cartridge includes a slide assembly including a cartridge holder for receiving the cartridge. The slide assembly is used for moving the cartridge holder from a loading position to a loaded position. An injection assembly is coupled to the slide assembly, and includes an injector movable relative to the slide assembly. The injector is movable into and out of an injection position, for piercing the cartridge to inject a liquid into the cartridge. A driving assembly is coupled to the injection assembly for moving the injection assembly into and out of the injection position. An extraction mechanism cooperates with the cartridge holder and includes an extractor that is movable between an extraction position for piercing the cartridge and extracting the beverage, and a non-use position.

2. The beverage dispensing apparatus according to claim 1, wherein the direction of movement of the slide assembly is substantially orthogonal to the direction of movement of the injection assembly.

3. The beverage dispensing apparatus according to claim 1, wherein the direction of movement of said extractor is substantially orthogonal to the direction of movement of said injector.

4. A beverage dispensing apparatus for extracting beverage from a cartridge, the beverage dispensing apparatus comprising:

a slide assembly including a cartridge holder for receiving the cartridge, the slide assembly for moving the cartridge holder from a loading position to a loaded position, the cartridge holder including an arch-shaped cavity for receiving the cartridge therein;

an injection assembly coupled to the slide assembly, the injection assembly including an injector movable relative to the slide assembly, into and out of an injection position, for piercing the cartridge to inject a liquid into the cartridge;

a driving assembly coupled to the injection assembly for moving the injection assembly into and out of the injection position;

an extraction mechanism cooperating with the cartridge holder and including an extractor movable between an extraction position and a non-use position, the extraction position for piercing the cartridge and extracting the beverage; and

a cartridge ejector mechanism, including an ejector biased downwardly for contacting said cartridge when said slide assembly is moved from said loaded position to said loading position.

5. The beverage dispensing apparatus according to claim 4, wherein said ejector is biased downwardly into contact with a surface of the cartridge holder for contacting a lip of said cartridge when said slide assembly is moved from said loaded position to said loading position, said ejector for inhibiting said cartridge from moving when said slide assembly moves from said loaded position into said loading position.

6. The beverage dispensing apparatus according to claim 4, further comprising a cartridge support with a semicircular cut-out portion for cooperating with the cartridge holder for supporting the cartridge.

7. The beverage dispensing apparatus according to claim 6, wherein said cartridge holder is adjacent said cartridge support when said cartridge holder is in said loaded position and said cartridge holder is spaced from said cartridge support when said cartridge holder is in said loaded position.

8. The beverage dispensing apparatus according to claim 7, wherein said arch-shaped cavity of said cartridge holder and said semi-circular cut-out portion of said cartridge support form a generally circular support when said cartridge holder is in said loaded position, for holding the cartridge therein.

9. The beverage dispensing apparatus according to claim 5, wherein said ejector displaces the cartridge from the cavity when the slide assembly moves from the loaded position to the loading position.

10. A beverage dispensing apparatus for extracting beverage from a cartridge, the beverage dispensing apparatus comprising:

a slide assembly including a cartridge holder for receiving the cartridge, the slide assembly for moving the cartridge holder from a loading position to a loaded position;

an injection assembly coupled to the slide assembly, the injection assembly including an injector movable relative to the slide assembly, into and out of an injection position, for piercing the cartridge to inject a liquid into the cartridge;

a driving assembly coupled to the injection assembly for moving the injection assembly into and out of the injection position;

an extraction mechanism cooperating with the cartridge holder and including an extractor movable between an extraction position and a non-use position, the extraction position for piercing the cartridge and extracting the beverage, wherein said extraction mechanism is coupled to said cartridge holder and said extractor moves between a non-use position and an extraction position for piercing the cartridge on a side wall thereof, by moving through an aperture in a side of the cartridge holder proximal a base of the cartridge holder.

11. A beverage dispensing apparatus for extracting beverage from a cartridge, the beverage dispensing apparatus comprising:

a slide assembly including a cartridge holder for receiving the cartridge, the slide assembly for moving the cartridge holder from a loading position to a loaded position;

an injection assembly coupled to the slide assembly, the injection assembly including an injector movable relative to the slide assembly, into and out of an injection position, for piercing the cartridge to inject a liquid into the cartridge;
