A system for evacuating and sealing containers filled with product, for example, food product, includes an enclosed, sealed housing wherein the pressure level and the atmospheric content can be controlled. A vacuum shroud is positioned in registry with a container entrance opening in the housing, the shroud connectible to a vacuum source and to a source of replaceable gas to replace the ambient air to be removed from the container. The shroud is advanceable to seal the container entrance opening and is retractable from the container entrance opening. A container transport system inserts the container through the housing entrance opening and into the shroud. Thereupon, a sealing system seals the housing from the ambient after the container has been inserted into the shroud. After the air in the container has been replaced with an inert gas and then the shroud retracted, a closure subsystem applies a cover to the evacuated container. Thereafter, an out feed subsystem removes the closed container from the housing while maintaining the atmospheric content and pressure level within the housing.

A device for opening, or re-closing, and holding lids of containers, each provided with an oblong spout, comprises a removal head of the pneumatic type which has a through housing channel which develops along an axis and in which the spout is at least partly housed, and a holding member, associated to the removal head, to cooperate with the spout. The holding member is actuated pneumatically to define at least a reversible condition of holding the spout inside the housing channel and comprises elastically deformable means which laterally delimit the housing channel. The elastically deformable means are configured to be deformed elastically by means of a fluid under pressure, so as to selectively define a reduction in section of the housing channel suitable to hold the spout.
