A closure device (2) for closing a flexible container (4), in particular a valve bag (4), has a welding device (14), a sensor device (20) for acquiring a position of a part of the container (4) to be closed (6), and a control unit (28). The control unit (28) is coupled with the sensor device (20) and with the welding device (14), and is configured to place the welding device (14) in a first position and a second position spaced apart from the first position on the part of the container (4) to be closed (6) by actuating at least one moving device, to detect when at least one of the two positions has been reached via the sensor unit (20), and to actuate the welding device (14) at the respective first and second position to generate a weld seam on the container (4).

A device for the packaging of products, particularly of the food type, includes a container made of material that is flexible and substantially impermeable to gases and water vapor. The container forms inside it a compartment for accommodating products and is provided with at least one passage opening for the introduction and/or evacuation of the products into/from the compartment. At least one functional port can be closed hermetically and is associated with the container in fluid communication with the accommodation compartment. At least one monitoring port is associated with the container in fluid communication with the accommodation compartment, which is adapted to allow the passage of fluid at least from the inside of the compartment toward the outside. An assembly for detecting at least one chemical-physical parameter of the atmosphere is located within the accommodation compartment.

A valve bag filling device for filling powdered filling material into a valve bag is provided, and has a filling spout (1), which is provided so as to be introduced into a valve hose of a valve bag to be filled. The device has a conveying device for conveying the filling material to be filled from a supply tank through the filling spout (1) into a valve bag resting on the filling spout (1) with the valve hose, as well as a suction device (3, 4) for aspirating excess filling material via a suction opening (5). The suction opening (5) is arranged spaced a distance (9, 10) from the filling spout (1). A control device is provided, with which the suction opening (5) can be traversed in a direction (6) in relation to the filling spout (1).
