METHOD FOR PRODUCING A DEVICE FOR DISPENSING FLUID PRODUCT UNDER PRESSURE, APPARATUS FOR IMPLEMENTING SUCH A METHOD AND DEVICE FOR DISPENSING FLUID PRODUCT UNDER PRESSURE

摘要

A method for producing a dispensing device (1) comprising the following steps: - 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), - 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.
