Method and assembly for evacuating a package (2), such as a vacuum package filled with a product such as nuts. The package is at least partially made of packaging film (6). The method employs a suction device (4) provided with a suction opening, for evacuating the package through an aperture (12) in the packaging film. The package is provided with a substantially plate-shaped, rigid element (8), one main surface of which substantially lying in contact 'with the inner side of the packaging film, wherein the aperture in the packaging film is provided at the location of the substantially rigid element. The method further includes the sealing abutment of the suction opening against an outer side of the package, at a location where the substantially rigid element lies in contact with the inner side of the packaging film, in such a way that the aperture is in fluid connection with the suction opening.
B65B 31/04 - Evacuating, pressurising or gasifying filled containers or wrappers by means of nozzles through which air or other gas, e.g. an inert gas, is withdrawn or supplied
B65B 31/08 - Evacuating, pressurising or gasifying filled containers or wrappers by means of nozzles through which air or other gas, e.g. an inert gas, is withdrawn or supplied the nozzle being adapted to pierce the container or wrapper
B65D 81/20 - Containers, packaging elements, or packages, for contents presenting particular transport or storage problems, or adapted to be used for non-packaging purposes after removal of contents providing specific environment for contents, e.g. temperature above or below ambient under vacuum or superatmospheric pressure, or in a special atmosphere, e.g. of inert gas
G01M 3/32 - Investigating fluid tightness of structures by using fluid or vacuum by measuring rate of loss or gain of fluid, e.g. by pressure-responsive devices, by flow detectors for containers, e.g. radiators
G01M 3/36 - Investigating fluid tightness of structures by using fluid or vacuum by detecting change in dimensions of the structure being tested

METHOD AND ASSEMBLY FOR DETERMINING THE PRESSURE PREVAILING IN A PACKAGE
Method and assembly for determining the pressure prevailing in a package, such as a vacuum pack filled with nuts, wherein the package is at least partly manufactured from packaging film, wherein the package is provided with a substantially rigid element that on an inner side of the package substantially lies in contact with the packaging film, wherein use is made of a measurement chamber that has an open side, wherein the open side sealingly abuts against an outer side of the package, on a location where the substantially rigid element substantially abuts against the inner side of the package, thus forming an enclosed volume between the measurement chamber and the package, wherein the pressure in the measurement chamber is substantially made equal to the pressure in the package and wherein subsequently the pressure in the measurement chamber is then determined.
