Abstract

Process for manufacturing a bag with a valve, starting from a tubular sleeve made of thermoplastic material, whose method consists of heating, at the desired temperature, for example higher than the melting point of said material, an area of said form sleeve and suitable dimensions, then in causing a deformation of this area, with a view to obtaining a tubular flexible tube, perpendicular to the axis of the sleeve, and that, after drilling the base that is farthest from the main wall of the bag, will constitute the valve.
