PACKAGING DEVICE WITH VACUUM NODE AND PACKING METHOD Russian patent published in 2019 - IPC B65B25/00 B65B31/02 

FIELD: control; regulation.

SUBSTANCE: device contains a control unit, a loading unit, configured to place a tubular film around the product to be packed, and a sealing unit associated with a control unit configured to control the sealing unit to create one or more seals on the tubular film. Device also contains a vacuum unit connected to the control unit and containing the first element and the second element, located opposite the first, which contains the deformable part. First and second elements are able to move relative to each other between the position of the first configuration, in which the first and second elements are separated from each other, the position of the second configuration in which the deformable part contacts at least part of the second element and / or part of the tubular film, which rests on the second element in use, and the position of the third configuration in which the deformable part is compressed in the compression direction towards the second element. Device also includes means for moving the product to and from the vacuum unit, the first element contains a latch, the deformable part is connected to the latch, facing the second element, has the shape of an apron connected to the latch, and forms the side wall of the chamber, and the apron part, which is at least 30 % in the vertical direction, consists of a deformable material or a deformable structure, or the deformable part contains a deformable area that has a bellows type structure, which is circumferentially along the second part. Invention is also a method which is carried out using the device described above.

EFFECT: group of inventions provides a reduction in volume and quality improvement.
