Process and dispensing system for preparing liquid concentrates for plastics
First Claim
1. A process for preparing a liquid concentrate for use in the manufacture of plastic parts comprising:
- (a) preparing one or more liquid intermediates, wherein the liquid intermediates comprise a liquid vehicle and at least one additive;
(b) standardizing the liquid intermediates;
(c) transferring the standardized liquid intermediates to a remote location; and
(d) dispensing the liquid intermediates to produce a liquid concentrate, wherein the quantity of each liquid intermediate dispensed is controlled according to a predetermined formula for the liquid concentrate.

Abstract
The invention provides a process for preparing a liquid concentrate for use in the manufacture of plastic parts (including without limitation, as part of the sampling, evaluation and approval process before a plastic part goes into production) comprising: (a) preparing one or more liquid intermediates, wherein the liquid intermediates comprise a liquid vehicle and at least one additive (which may include a pigment, dye or other additive); (b) standardizing the liquid intermediates; (c) transferring the standardized liquid intermediates to a remote location; and (d) dispensing the liquid intermediates to produce a liquid concentrate, wherein the quantity of each liquid intermediate dispensed is controlled according to a predetermined formula for the liquid concentrate. The present invention also provides a process for preparing a liquid concentrate for use in the manufacture of plastic parts comprising: (a) providing one or more-liquid intermediates, wherein the liquid intermediates comprise a liquid vehicle and at least one additive (which may include a pigment, dye or other additive), wherein the liquid intermediates are standardized, and wherein the liquid intermediates have been prepared remotely; and (b) dispensing the liquid intermediates to produce a liquid concentrate, wherein the quantity of each liquid intermediate dispensed is controlled according to a predetermined formula for the liquid concentrate. The present invention also provides a process for preparing a liquid concentrate as described above using a dispensing system which includes a dispensing machine and mixing equipment which may be controlled by a computer or operated manually at the location where the dispensing is done to produce the liquid concentrate; and which may include the manual “hand add” of one or more components of the predetermined formula before the mixing step.

20. A dispensing system to prepare a liquid concentrate for use in the manufacture of plastic parts comprising:
-
(a) a plurality of containers each containing a standardized liquid intermediate prepared at a location remote from the dispensing system; and
(b) a dispensing machine for dispensing a plurality of liquid intermediates to produce a liquid concentrate, wherein the quantity of each liquid intermediate dispensed is controlled according to a predetermined gravimetric formula for the liquid concentrate, wherein the quantity of each liquid intermediate is controlled by a computer that contains the predetermined gravimetric formula, and wherein the dispensing of the liquid intermediates is controlled by the computer.
