Abstract: A method for gas filling a handle portion of a container of a collapsible type. The handle portion being defined by two opposite side walls of the container and communicating, via a duct defined by the side walls, with an opening formed in one of the side walls. The method including the steps of supplying, at a gas filling station, a gas to the handle portion via the opening and the duct, blocking the duct by squeezing action to retain the gas supplied to the handle portion, transporting the container to a sealing station while maintaining the squeezing action and, at the sealing station, sealing the duct while maintaining the squeezing action, so as to permanently enclose the gas in the handle portion. The disclosure further concerns a container of a collapsible type.

Abstract: A system for filling a package of the collapsible type with a product in the form of a powder or liquid having a package, which has a chamber defined by flexible walls, and an arrangement for filling a package of the collapsible type with a product in the form of a powder or liquid.

Abstract: A filling device (100) for filling a container (1) with a liquid has a filling duct (15) which is connected to a storage tank. On a carrying means (10) there are arranged a deformable tube (20) which forms a throttle portion (22) in the duct (15), and a squeezing means (30) which is arranged along the tube and which is adapted to act on the sides of the tube (20) and which, when operated to close the duct, is adapted to move countercurrently to generate a subatmospheric pressure in the duct (15) downstream of the squeezing means (30). The filling device also has a meter for measuring a discharged amount of liquid.
