Abstract
A method of bottling liquids, in particular carbonated liquids or liquids sensitive to oxygen, on a machine comprising a conveying device movable along a given path and having at least one unit for receiving and retaining a bottle, the method comprising filling the bottle with a liquid as the unit travels along a first portion of the path; and capping the bottle with a cap as the same unit travels along a second portion of the path. Also, A bottle as obtained by the method and also comprising a further cap applied onto a neck of said bottle and provided with coupling means to engage and pull said cap along the bottle axis upon removal of said further cap from said neck so as to open the bottle.

A method of bottling liquids, in particular carbonated liquids or liquids sensitive to oxygen, on a machine comprising a conveying device movable along a given path and having at least one unit for receiving and retaining a bottle, wherein the machine comprises, for each said unit, a respective fill-and-cap head movable along the given path and comprising a cavity having a first opening facing the unit and a movable wall having a collar shape and slidable to laterally limit part of said cavity, the method comprising:
- filling the bottle with a liquid as the unit travels along a first portion of the given path;
- capping the bottle with a cap as the same unit travels along a second portion of the given path;
- moving the bottle through the first opening to close the cavity in fluidtight manner and define a chamber;
- connecting the chamber to a feed device for feeding the liquid into the bottle
- moving the cap inside the chamber and into position facing the bottle;
- moving the bottle through the first opening and against the cap to cap the bottle inside the chamber
- feeding a pressurized gas into the chamber before capping the bottle with the cap;
- and
- sliding the movable wall when capping the bottle to maintain a substantially constant volume of the chamber.
A machine for bottling liquids, in particular carbonated liquids, the machine comprising:
- a conveying device having at least one unit for receiving and retaining a bottle and which is fed by the conveying device along a given path;
- a feed device for feeding the liquid into the bottle as the unit travels along a first portion of the given path;
- a fill-and-cap head for capping the bottle with a cap as the unit travels along a second portion of the given path, wherein the fill-and-cap head is movable along the path and having a cavity having a first opening facing the unit, the fill-and-cap head comprising a movable wall having a collar shape and slidable to laterally limit part of the cavity and is movable when the bottle is moved inside the cavity to maintain a substantially constant volume of the cavity;
- and
- a feed device for feeding the cap into the chamber and into position facing the bottle;
- wherein the unit is movable crosswise to the path to move the bottle through the first opening to seal the cavity in fluidtight manner and define a chamber connectable to said feed device for feeding the liquid into the bottle.
