Abstract
Disclosed is a method for producing a dispensing device (1). The method includes mounting a valve (4) into a dispensing opening (7) of an internal reservoir (3) with a variable volume, sealingly attaching an attachment sleeve (22) made of thermoplastic polymer to the internal reservoir (3), disposing the internal reservoir (3) and the valve (4) inside an external container (5) made of thermoplastic polymer, placing the attachment sleeve (22) opposite to and at a distance from a mounting opening (16) of the external container (5), inserting through the mounting opening (16) a pressurized gas between the internal reservoir (3) and the external container (5), and closing off the mounting opening (16) with the attachment sleeve (22) and welding the attachment sleeve (22) and the external container (5) to one another.
