A drum structure for laundry treatment device and a method of manufacturing a drum are disclosed. The drum structure for laundry treatment device includes a drum center formed of a metal sheet in a cylindrical shape having a hollow, and the drum center includes a reduced drum portion formed by reducing both ends of the drum center, and a curved portion formed in the reduced drum portion. The drum structure for laundry treatment device and the method of manufacturing a drum do not need to separately manufacture a drum front and a drum rear, do not require separate molds for the manufacture of the drum front and the drum rear, and can reduce the overall manufacturing cost.

In an example, a method for milling a sink is disclosed. The method includes receiving a metal sheet, positioning the metal sheet in a receiving assembly for a milling machine, and scoring the metal sheet via a cutter of the milling machine. The metal sheet is scored along an axis corresponding to a bend of the sink. The method also includes manipulating the metal sheet to form the sink.

The invention relates to a dispenser container for pressurized fluids, comprising: a metal shell forming at least part of an outer wall of the container, which metal shell at least partly encloses an internal container volume, a partition wall separating internal container volume into a high-pressure chamber and a low-pressure chamber, and a valve mounted into the partition wall in a substantially fluid-tight manner, which valve is configured for a controlled release of fluid from the high-pressure chamber to the low-pressure chamber, wherein the partition wall is at a sealing zone sealed to the metal shell in a substantially fluid-tight manner, and wherein the metal shell delimits at least a part of the high pressure chamber. The invention further relates to a dispenser comprising such a dispenser container and a method for manufacturing such a dispenser container.
