An apparatus for producing plastic bottles comprising: a blow moulding machine including a blow moulding carousel being configured to transform a succession of plastic preforms into respective bottles; a filling machine including: a filling carousel, and a plurality of handling units; a labeling unit configured to feed a succession of labels to be attached to the respective bottles; and a conveying system configured to transfer the bottles within the apparatus. The labeling unit is arranged peripherally to the filling carousel and is configured to feed the labels to the handling units carrying the respective bottles while the handling units are advanced by the filling carousel. The conveying system includes a plurality of consecutive transport star wheels transferring the bottles in a continuous stream from the blow moulding carousel to the filling carousel.

A filling valve group for a filling machine, comprising a supply duct for delivering a liquid into a container, an air return tube, and a shutter provided with a narrowing portion fixed to the supply duct and an enlarged portion fixed to the air return tube. In addition, the filling valve group comprises a centering body, which is placed at the outlet section of the supply duct to abuttingly receive the mouth of the container, and is removably fixed to a lower portion of the filling valve group by a first quick coupling. The filling valve group further comprises a fixed assembly, which forms an upper section of the supply duct, and a removable tube, which forms a lower section of the supply duct, carries fixed thereto the narrowing portion of the shutter and is removably fixed to the fixed assembly by a second quick coupling.

A gas stem assembly is disclosed including a vent tube having at least one protrusion extending radially from the vent tube and a receiver having a non-circular opening and an attachment surface at an end of the non-circular opening. The vent tube is at least partially insertable through the non-circular opening of the receiver when the vent tube and the at least one protrusion are aligned with the non-circular opening. The attachment surface of the receiver contacts the at least one protrusion to inhibit the at least one protrusion from passing back through the non-circular opening when the at least one protrusion is misaligned with the non-circular opening.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head.

A valve assembly for a machine for filling containers with a liquid has an adduction conduit extending along a valve axis and connectable to a tank of the filling machine to allow inflow of the liquid through a discharge mouth. A shutter arranged inside the adduction conduit and moving along the valve axis between a closing position and one or more opening positions has an annular gasket that with the shutter in the closing position sealingly engages an abutment seat. The annular gasket has a first annular portion for sealingly engaging a first portion of the abutment seat, and a second annular portion for sealingly engaging a second portion of the abutment seat. At least one flow window interrupts an annular continuity of the second annular portion and allows a partialized flow of liquid through the adduction conduit when the first annular portion is spaced apart from the abutment seat.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head.

A device for filling cans includes a filling valve, a gas channel and a seal. The seal is connected to the gas channel for receiving a compressed gas and is elastically deformable by the received compressed gas in a downward direction for pressing against a peripheral upper edge of a can positioned below the filling valve. Advantageously, the device can enable a secure sealing of the inlet gap between the can and the filling valve with comparatively low contact forces via the downwardly elastically deformable seal, so that even very thin-walled cans can be filled without risk of damage.

Systems, methods, and apparatus are disclosed herein for counter pressure filling. In particular, embodiments of the present disclosure provide for independently operated filling nozzles for establishing counter pressure of containers when supplying carbonated liquid to provide consistent quality and improve product characteristics. The flow rate of the carbonated liquid can be manipulated based on the counter pressure maintained by the system during the filling cycle.
