## Abstract

The invention relates to a device for delivering a beverage into a thermoplastic container formed from a heated preform, the preform being approximately cylindrical and positioned in a mold, characterized in that it includes injection unit for injecting at least one beverage into a recess in the preform so as to promote expansion of the preform inside the mold, the mold defining the shape of the container, the injection unit comprising an injection head designed to inject at least one beverage through a mouth of the recess, the injection head being integrated into the mold.

## Claims

### Claim 1

A device for delivering a beverage into a thermoplastic container formed from a heated preform, the preform being positioned in a mold, the device comprising an injector for injecting at least one beverage into a recess in the preform so as to promote expansion of the preform inside the mold, the mold defining the shape of the container, the injector comprising at least one injection head designed to inject at least one component of the beverage through a mouth of the recess, at least part of the at least one injection head being defined by the mold, the at least one injection head including a spout on an end of a duct perpendicular to a longitudinal axis of a container cavity defined in the mold, the spout being oriented parallel to the longitudinal axis, and an axially moveable stretch rod extending through a passageway defined in the mold.

### Claim 2 (depends on 1)

The device according to claim 1, comprising means for forming the container using air, up to a fraction of its final volume, and means for increasing the internal pressure in the container, the formation being accomplished using the beverage.

### Claim 3 (depends on 1)

The device according to claim 1, comprising a means for pressurizing a volume of beverage to be injected.

### Claim 4 (depends on 3)

The device according to claim 3, wherein the pressurizing means comprises one of a pump, a piston and a central pressurized air reservoir.

### Claim 5 (depends on 1)

The device according to claim 1, comprising a system for degassing the beverage.

### Claim 6 (depends on 1)

The device according to claim 1, comprising a cleaner for cleaning at least part of the mold.

### Claim 7 (depends on 1)

The device according to claim 1, wherein the mold consists of a mold base and two upper mold parts.

### Claim 8 (depends on 1)

The device according to claim 1, wherein the at least one injection head is placed so as to allow a stopper fixing member to operate.

### Claim 9 (depends on 8)

The device according to claim 8, wherein an upper part of the mold has at least two configurations, the at least one injection head being at least partly defined by the upper part, the at least one injection head being capable of injecting the beverage into the preform in the first configuration, and the stopper fixing member being designed to position a stopper on the neck of a preform in the second configuration.

### Claim 10 (depends on 1)

The device according to claim 1, further comprising a stopper that can be positioned on a neck of the recess.

### Claim 11 (depends on 1)

The device according to claim 1, wherein the spout is separately defined in the mold from the passageway through which the stretch rod extends.

### Claim 12

A for delivering a beverage into a thermoplastic container formed from a heated preform, the preform being positioned in a mold, the device comprising an injector for injecting at least one beverage into a recess in the preform so as to promote expansion of the preform inside the mold, the mold defining the shape of the container, the injector comprising two injection heads designed to inject at least one component of the beverage through a mouth of the recess, at least part of the two injection heads being defined by the mold, each of the two injection heads including a spout on an end of a duct perpendicular to a longitudinal axis of a container cavity defined in the mold, the ducts being connected to a circuit for supplying at least one constituent of the beverage, and an axially moveable stretch rod extending through a passageway defined in the mold and wherein the ducts are located on opposing sides of the stretch rod.

### Claim 13 (depends on 12)

The device according to claim 12, wherein the ducts are integrated into a top part of the mold.

### Claim 14 (depends on 12)

The device according to claim 12, comprising means for forming the container using air, up to a fraction of its final volume, and means for increasing the internal pressure in the container, the formation being accomplished using the beverage.

### Claim 15 (depends on 12)

The device according to claim 12, comprising a means for pressurizing a volume of beverage to be injected.

### Claim 16 (depends on 15)

The device according to claim 15, wherein the pressurizing means comprises one of a pump, a piston and a central pressurized air reservoir.

### Claim 17 (depends on 12)

The device according to claim 12, comprising a system for degassing the beverage.

### Claim 18 (depends on 12)

The device according to claim 12, comprising a cleaner for cleaning at least part of the mold.

### Claim 19 (depends on 12)

The device according to claim 12, wherein the mold consists of a mold base and two upper mold parts.

### Claim 20 (depends on 12)

The device according to claim 12, wherein the two injection heads are placed so as to allow a stopper fixing member to operate.

### Claim 21 (depends on 20)

The device according to claim 20, wherein an upper part of the mold has at least two configurations, the two injection heads being at least partly defined by the upper part, the two injection heads being capable of injecting the beverage into the preform in the first configuration, and the stopper fixing member being designed to position a stopper on the neck of a preform in the second configuration.

### Claim 22 (depends on 12)

The device according to claim 12, further comprising a stopper that can be positioned on a neck of the recess.

### Claim 23 (depends on 12)

The device according to claim 12, wherein each spout is separately defined in the mold from the passageway through which the stretch rod extends.
