Abstract
The invention relates to a method for manufacturing a dispenser container for pressurized fluids, comprising the steps of providing a cylindrical; a partition wall for separating the internal volume of the cylindrical shell; and a piston; and bringing the partition wall and piston together into the lower part of the cylindrical shell before applying an external indent in the cylindrical shell. The invention further relates to a dispenser container for pressurized fluids as manufactured with this method.
Claims21
Method for manufacturing a dispenser container for pressurized fluids, comprising the steps of:
- A) providing a cylindrical shell with a bottom and an open top, forming at least part of the outer wall of the dispenser container;
- B) providing a partition wall for separating the internal volume of the cylindrical shell into a high-pressure chamber and a fluid chamber, with a valve mounted into the partition wall;
- C) providing a piston to be moveably positioned in the fluid chamber;
- D) bringing the partition wall and the piston together into the lower part of the cylindrical shell;
- and
- E) after step D) applying at least one external indent in the cylindrical shell, which indent extends as a protrusion into the internal volume of the cylindrical shell;
- whereby the partition wall is located at the height where the external indent is applied or whereby the partition wall and the piston are located on the bottom side in the cylindrical shell of the location where the external indent is applied.
