Summary: | 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.
La invención se relaciona con un pistón para un recipiente opcionalmente presurizado, el pistón tiene una pared lateral, un lado superior y un lado inferior, y al menos un primer sello circunferencial, en donde al menos el lado superior del pistón se cierra mediante un cierre y se elabora de un primer material elástico, en donde el lado superior se configura para deformarse sobre un cambio de presión que actúa sobre el lado superior, en donde la pared lateral se elabora de un segundo material que es diferente del primer material elástico, en donde el primer sello circunferencial se ubica sobre la pared lateral sobre su superficie exterior. La invención se relaciona, además, con un recipiente presurizado opcionalmente presurizado que comprende un pistón como se mencionó anteriormente, con un proceso para descargar un producto de dicho recipiente y a un proceso para fabricar dicho recipiente. |
