Filling devices for lever filling of bottles with liquids are provided. Such devices may include a body having a vertical inner cavity, an outer tube which is fixed at the top to a bottom wall of a main vessel intended to contain the liquid with which the bottles are to be filled, extending through the inner cavity of the body and projecting downward from the body, an inner tube which is arranged coaxially with the outer tube, extending with a lower portion thereof inside the outer tube and projecting upward from the outer tube, so as to reach with its top end a level higher than the level of the liquid contained in the main vessel. Filling machines containing such devices are also provided.

A liquid filling apparatus has a vertical tube with bottom opening opened and closed by a valve. The tube is insertable into a container from above and supplies liquid to the container. A flexible separating disk extends radially from the bottom end of the tube. The tube with flexible separating disk is movable toward the container bottom and air in the container escapes between peripheral rim of the separating disk and container wall as the tube moves down until the flexible separating disk rests on the container bottom. The tube with flexible separating disk then is moved upwardly so that, between flexible separating disk and container bottom, an enlarging space is formed with upward movement. Liquid is supplied into this space through the open tube opening as upward movement continues. When a targeted liquid level is reached, the valve closes and the tube is pulled from the container.

Disclosed is a method of forming a packaging, the method including the steps of: providing an empty container including a sidewall, an opneck and a base, the container further including a invertible diaphragm in an outwardly-protruding position; a filling step of pouring, within the container through the neck, a product at a temperature lower than or equal to ambient temperature; a capping step of sealingly closing the filled container by way of a cap mounted onto the neck; an inversion step of displacing the diaphragm to an inwardly-protruding position, the inversion step being conducted within seconds after sealingly closing the container.

The present invention relates to a filler machine and method. The filler machine and method allow efficient and/or accurate filling of containers such as bottles, and have particular application to filling bottles or similar containers with carbonated beverages.
