Method and device for processing containers

A method for processing containers comprising, for each container to be treated,

• a) an assembling step for assembling a cap with a cover on a container, said cap comprising a tubular base and a cover pivotably connected to said base by means of an articulation between an open position and a closed position, said cap being assembled via said base on said container on an opening of said container,
• b) a step of sterilizing the container equipped with said cap having said cover, and
• c) a step of filling the container, said step of filling comprising maneuvering the cover into open position, filling of the container with a filling product, with the cover of said cap in said open position, and maneuvering the cover towards said closed position, wherein the maneuvering of the cover between the cover's two positions is carried out by relative movement of an actuating system in relation to the cap, said actuating system able to cooperate with at least one actuating member complementary to the cover in order to move the cover between said two positions, wherein said actuating system comprising a hollow cylindrical part, referred to as an actuating cylinder, comprising a central passage, an open upper end and an open lower end, the internal surface of the actuating cylinder being provided, on the side of its lower end, with an annular groove defined between a circular upper edge and a circular lower edge, the circular upper edge being offset towards the interior in relation to the lower edge,
• wherein at steps b) and/or c) before maneuvering of the cover the method comprises providing the container provided with the cap with said cover in closed position and arranging said container under said actuating cylinder, the longitudinal axes of said base and of said actuating cylinder being aligned, and wherein the manoeuvring of the cover is carried out by:
• for opening the cover, carrying out downwards a relative movement of the actuating cylinder in vertical translation, such that the lever passes beyond the lower edge, which is retracted in relation to the upper edge, and the actuating cylinder comes into a lower position to press via the upper edge against the lever and pivots the cover in order to open it, and
• for closing the cover, raising the actuating cylinder from said lower position, such that said lower edge presses on a lever and pivots the cover towards its closing position.
