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 3):
The piston of any one of  claim 1 , wherein the piston has at least one of these features:\n i) the piston has a maximum seal diameter, which is from about 0 to about 11% larger than a maximum diameter of the sidewall; ii) the sidewall of the piston is configured to deform under pressure; iii) the first circumferential seal is positioned on the sidewall in proximity to the upper side of the piston; iv) the piston has a height, which is in the range from about 25% or more than the maximum diameter of the piston, wherein the height is determined in the direction of the axis of movement of the piston; v) the second material comprises at least one element selected from the group consisting of a metal, an alloy, a material based on or derived from cellulose, a fibrous material, a thermoplastic and an elastomer; and vi) the first circumferential seal is made of a material comprising at least one element selected from the group consisting of an elastomer, a thermoplastic elastomer (TPE), a thermoplastic olefin (TPO), a thermoplastic urethane (TPU), silicone, butyl rubber (butyl), butyl methacrylate (buma) and a urethane-low density polyethylene copolymer (ULDPE).
