Abstract:
The invention relates to a piston for an optionally pressurized container, the piston having a sidewall, an upper side and a bottom side, and at least a first circumferential seal, wherein at least the upper side of the piston is closed by a closure and made of a first elastic material, wherein the upper side is configured to deform upon a pressure change acting on the upper side, wherein the sidewall is made of a second material which is different from the first elastic material, wherein the first circumferential seal is positioned on the sidewall on its outer surface. The invention further relates to an optionally pressurized container comprising a piston as mentioned above, to a process of discharging a product from said container and to a process of manufacturing said container.

Claim (Index 14):
A process of manufacturing a pressurized container, comprising at least these steps:\n a.) Providing a container body precursor having a first hole at one end of the container, and an open end; b.) Placing a piston as in  claim 1  in the container body precursor which seals a first chamber in the container body precursor designed to comprise a product; c.) Closing the open end of the container body precursor with a sealable bottom closure to form a second chamber; d.) Pressurizing the second chamber with a propellant and sealing the second chamber propellant-tight to form the pressurized container; e.) Loading a product into the pressurized container.
