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′).
Claims6
A dispensing system integrally formed with a collapsible, pouch- or bag-style container, the system comprising:
- first and second identically-shaped plastic members;
- a container-forming film enveloping the coupled plastic members and sealed along a peripheral edge of the film;
- wherein each plastic member includes an elastically-yielding hemispherical section with a periphery in which a first duct portion is formed spaced apart from a second duct portion and wherein the first duct portion includes a valve formation that is shaped differently in comparison to a valve formation in the second duct;
- wherein the first and second plastic members are oriented so that the first duct of the first member abuts the second duct of the second member, wherein the first and second plastic members are coupled together by a continuous rib and an opposing groove formed around the hemispherical section of each plastic member thereby creating a collapsible chamber defined by the hemispherical sections and inlet and outlet channels defined by the duct portions.
