Abstract
The present invention concerns a system (1; 501; 601; 701; 801) for dispensing a fluid (L), comprising a container (C; C′) for the fluid (L) and a device (10; 210; 210′; 310; 410; 410′) for dispensing the fluid (L). The device (10; 210; 210′; 310; 410; 410′) comprises a collapsible chamber (20) which defines a volume (V) suited to receive a quantity of said fluid (L) to be dispensed. The chamber (20) is defined by a first portion (30) and a second portion (130) mutually coupled with each other, wherein the first portion (30) comprises an area connected to the container (C; C′) and wherein the second portion (130) comprises an area connected to the container (C; C′).
