Automatic capping machine for containers in the food sector, by means of twist-off lids, carried out in a totally automated way, with the simultaneous application of a vacuum in the container to prevent air from entering in it, which would significantly reduce the preservation time of the food contained inside.

The invention presented affords the main advantage of performing container capping in high-vacuum conditions, using conventional containers that are standard in the glass market, with metal twist-off lids, making food packaging possible without requiring any type of covering liquid inside the container, as well as allowing the control and pre-configuration of the lid closing torque before initiating the work cycle.

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.

An apparatus for vacuum-sealing a lid onto a jar includes a cap skirt joined to a cap. The cap and cap skirt are formed with internal threads for engaging corresponding external threads on the jar. A lid for the jar placed against the lid press will be drawn against the rim of the jar after air is pumped out of the jar through the cap. An airtight seal is established between the lid and the rim of the jar when air at normal atmospheric pressure enters the vacuum port, the pressure difference between the outside and inside of the jar forcing the lid onto the jar rim and sealing the jar. A prying plate positioned on the top of the cap permits removal of the lid without deforming the lid beyond its elastic limit, enabling lids to be removed and re-sealed against the jar.
