Method and device for intimate mixing of two components in a package
First Claim
Patent Images
1. A method for intimately mixing at least two mutually barely miscible or paste-like components (A,B) with each other, wherein, initially, the different components are kept in separate storage compartments (16,17;
- 29,30;
31a,b;
33;
34;
35) in a flexible package (2), said method comprising the steps of (a) applying external pressure to the package and causing the components to flow into a common compartment (20a-d;
37a-37c;
41a-c;
44a-c) while being mixed together,(b) applying an external pressure to the common compartment and building up an increased internal pressure in the common compartment; and
(c) causing the components (A,B) to flow explosively together into an adjacent compartment while being intimately mixed with each other.

Abstract
A method and a device for intimately mixing two or more liquid or paste-like components inside a flexible plastic package (2). A squeezing roller (3) causes the components to be fed forward step by step between different compartments in the package, whereupon the discharge from one compartment to the next occurs suddenly and explosively, so that intimate and effective mixing of the components (A,B) is achieved.
