Disclosed is a device (1) for filling a container of a collapsible type with a product in the form of powder or liquid. The container has a compartment which is defined by flexible walls and whose volume is dependent on the relative position of the walls. The container is filled through a filling duct. The container includes a valve housing (2) with a filling tube (5), which is insertable into the filling duct of the container to supply a product to the compartment of the container through a product path. The product path is defined by the valve housing and its filling tube, a piston element (4) arranged in the product path and comprising a valve body (11) and, arranged downstream thereof, an end element (12). The piston element and end element are movable between two positions. In a first position, the valve body abuts against a valve seat (7) of the valve housing to block the product path and the end element is arranged in or adjacent to an outlet portion (6) of the filling tube to counteract dripping. In a second position, in which the valve body is displaced from the valve seat to open the product path and the end element takes a position, in which it defines, together with the outlet portion, a filling passage. The container also has a squeezing means (3), which grips the filling tube and the filling duct to seal between them. The filling tube is made of a rigid material.
