Working line for fluidic or fluid products contained in pre-dosed containers, wherein a container comprises at least one cover and/or one lid for closing it; said working line comprising: - a first manipulation station comprising at least one manipulator adapted to manipulate covers and/or lids associable with said container through joint-type and/or screw type means, and adapted to manipulate said cover and/or lid so as to remove said cover and/or lid from said container, thereby opening the latter; - at least one working station adapted to carry out at least one operation on the fluid product contained in the container after the removal of said cover and/or lid from the container; - a second manipulation station comprising at least one manipulator adapted to manipulate covers and/or lids associable with said container through joint-type and/or screw type means; - a transportation system adapted to move the pre-dosed containers among the different stations (3, 5, W); said at least one working station is located between said first manipulation station and said second manipulation station; said working line comprising a movement system adapted to move covers and/or lids at least between said first manipulation station and said second manipulation station; said working line being characterized in that: said movement system comprises: - at least one movement device adapted to move said covers and/or lids between said first manipulation station and said second manipulation station; - at least two conveyance systems adapted to allow said covers and/or lids to appropriately move from said manipulator (4, 6) to said movement device, and vice versa; - a plurality of anti-dripping systems adapted to avoid that, at least while said covers and/or lids are being moved between the conveyance systems and the manipulators (4, 6), part of the fluid product might soil the containers, said covers and/or lids, and/or part of the working line; and in that the at least one manipulator at the second manipulation station is adapted to manipulate the cover and/or lid removed from a container at said first manipulation station so as to associate the cover and/or lid with the same container from which it was removed, thereby closing it, when the same container arrives at the second manipulation station. - a first manipulation station comprising at least one manipulator adapted to manipulate covers and/or lids associable with said container through joint-type and/or screw type means, and adapted to manipulate said cover and/or lid so as to remove said cover and/or lid from said container, thereby opening the latter; - at least one working station adapted to carry out at least one operation on the fluid product contained in the container after the removal of said cover and/or lid from the container; - a second manipulation station comprising at least one manipulator adapted to manipulate covers and/or lids associable with said container through joint-type and/or screw type means; - a transportation system adapted to move the pre-dosed containers among the different stations (3, 5, W); said at least one working station is located between said first manipulation station and said second manipulation station; said working line comprising a movement system adapted to move covers and/or lids at least between said first manipulation station and said second manipulation station; said working line being characterized in that: said movement system comprises: - at least one movement device adapted to move said covers and/or lids between said first manipulation station and said second manipulation station; - at least two conveyance systems adapted to allow said covers and/or lids to appropriately move from said manipulator (4, 6) to said movement device, and vice versa; - a plurality of anti-dripping systems adapted to avoid that, at least while said covers and/or lids are being moved between the conveyance systems and the manipulators (4, 6), part of the fluid product might soil the containers, said covers and/or lids, and/or part of the working line; and in that said working line comprising a movement system adapted to move covers and/or lids at least between said first manipulation station and said second manipulation station; said working line being characterized in that: said movement system comprises: - at least one movement device adapted to move said covers and/or lids between said first manipulation station and said second manipulation station; - at least two conveyance systems adapted to allow said covers and/or lids to appropriately move from said manipulator (4, 6) to said movement device, and vice versa; - a plurality of anti-dripping systems adapted to avoid that, at least while said covers and/or lids are being moved between the conveyance systems and the manipulators (4, 6), part of the fluid product might soil the containers, said covers and/or lids, and/or part of the working line; and in that - at least one movement device adapted to move said covers and/or lids between said first manipulation station and said second manipulation station; - at least two conveyance systems adapted to allow said covers and/or lids to appropriately move from said manipulator (4, 6) to said movement device, and vice versa; - a plurality of anti-dripping systems adapted to avoid that, at least while said covers and/or lids are being moved between the conveyance systems and the manipulators (4, 6), part of the fluid product might soil the containers, said covers and/or lids, and/or part of the working line; and in that
