Abstract
A flexible film fluid-dispensing device including (A) at least one flexible film liner member having a flexibility property of from 3.6e-10 Nm to 2 Nm; (B) a rigid frame member for receiving the flexible film liner member and for removably holding the flexible film liner member in place during the flow of fluid through the flexible fluid-dispensing device; and (C) a connection means for connecting the flexible film fluid-dispensing device to the outlet feed stream of a fluid production process line; a process of manufacturing the above flexible film fluid-dispensing device; and a process for dispensing a fluid using the above flexible film fluid-dispensing device.
Claims11
A flexible film fluid-dispensing device comprising:
- (A) at least one flexible film member having a flexibility property of from 3.6e-10 Nm to 2 Nm;
- wherein the flexible film member includes:
- (i) at least one fluid inlet aperture,
- (ii) a plurality of outlet apertures, and
- (iii) a series of flexible inflatable and deflateable fluid flow path ducts integral with the at least one fluid inlet aperture and the plurality of outlet apertures for passing a fluid through the fluid flow ducts and out of the flexible film member;
- (B) a rigid frame member for receiving at least one edge of the flexible film member and for holding the flexible film member in place during the flow of fluid through the flexible multilayer film member;
- and
- (C) a connection means for connecting the flexible film member to the outlet feed stream of a fluid production line, wherein:
- the at least one flexible film member, component (A), includes a multilayer flexible film fluid-dispensing liner member;
- wherein the multilayer flexible film fluid-dispensing liner member includes:
- (a) at least one first flexible film substrate layer;
- and
- (b) at least one second flexible film substrate layer;
- the at least one first flexible film substrate layer is bonded to the at least one second flexible film substrate layer;
- wherein the first and second substrates of the multilayer flexible film fluid-dispensing liner member are constructed of a material adapted for use with and contacting a polyurethane composition fluid;
- and
- the multilayer flexible film fluid-dispensing liner member has a flexibility property of from 3.6e-10 Nm to 2 Nm as calculated by the following equation:

- (ii) a plurality of outlet apertures, and
- (iii) a series of flexible inflatable and deflateable fluid flow path ducts integral with the at least one fluid inlet aperture and the plurality of outlet apertures for passing a fluid through the fluid flow ducts and out of the flexible film member;
- (B) a rigid frame member for receiving at least one edge of the flexible film member and for holding the flexible film member in place during the flow of fluid through the flexible multilayer film member;
- and
- (C) a connection means for connecting the flexible film member to the outlet feed stream of a fluid production line, wherein:
- a first film substrate inner layer is bonded to a second film substrate inner layer by heat-sealing the substrates using a heating sealing die wherein, upon bonding the first film substrate inner layer to the second film substrate inner layer together the heat sealing forms (i) at least one fluid inlet aperture, (ii) a plurality of fluid outlet apertures, and (iii) a series (or pattern) of flexible fluid flow path ducts (or passageways) are formed in the flexible multilayer film member for passing a fluid therethrough.
