A chamber conveyor belt machine having a machine frame, a chamber cover with two or more columns and a lifting device for lifting the chamber cover. The lifting device may include a safety system that includes a latching rail that cooperates with a latching hook disposed on at least one of the two columns. The safety system may include one or more sensors for determining whether the lifting device is working correctly or is in a failure condition. The safety system may prevent the chamber conveyor belt machine from operating if a failure condition is sensed.

A container is provided with a flange defining a container opening that may help expunge food product as the film and seal head comes down on the container flange. The flange of the container opening has a predetermined angle. The container flange with its sealing surface generally deflects or angularly pivots when sealed with the film during the sealing process. The container flange and film may push product contamination from the sealing surfaces inwardly into the container. The flange may be continuous about the periphery of the container opening.

There is provided a moisture-sensitive vacuum packing machine, and particularly, there is provided a moisture-sensitive vacuum packing machine for sensing moisture within a chamber. The moisture-sensitive vacuum packing machine includes: a device housing having a controller and a vacuum driving unit; a chamber unit positioned above the device housing and having a first chamber and a second chamber whose interiors are vacuumized when the vacuum driving unit operates; and a sensing unit installed in the chamber unit such that it is associated with the controller, and sensing the presence or absence of moisture within the second chamber according to whether the sensing unit comes into contact with the second chamber.

The utility model discloses a cavity-type vacuum sealing machine, comprising a machine body and a cover which covers the machine body. The machine body is internally provided with a tray; an airtight cavity for holding packaging bags is formed between the tray and the cover; the cavity is internally provided with a hot-pressing bar and a heating and sealing component for sealing the packaging bags; the machine body is internally provided with a vacuum pump set for vacuumization; and the suction ports of the vacuum pump set communicate with the airtight cavity for holding the packaging bags via tubes. The cavity-type vacuum machine disclosed by the utility model has the advantages of smaller volume and small occupied space.

The invention relates to a filling and closing device (20) for an applicator for active substances (1) and to a method for filling and closing such an applicator for active substances (1) by means of such a filling and closing device (20). The applicator for active substances (1) comprises an applicator tube (7) that overlaps the sealing edge (5), at least in part. The filling and closing device (20) comprises a receiving element (21) for the lower part (2) of the applicator for active substances (1), having a circumferential pressure surface (22) and a receiving channel (23) for the applicator tube (7), said receiving channel extending below the pressure surface (22). The receiving element (21) is constructed of at least two parts, having a base element (24) and a cover element (25) that is movable with respect to the base element (24). After completion of the filling and sealing process, the cover element (25) is moved relative to the base element (24), such that the receiving channel (23) formed therebetween is exposed. The filled and sealed applicator for active substances (1) can then be easily removed from the receiving element (21) by way of the applicator tube (7).
