Multicomponent Dispensing Device For Liquid And Powdery Materials

Abstract

A multicomponent dispensing device for liquid and powdery materials comprises a blister part having at least two chambers that are arranged adjacent each other and sealed by means of a film, a blister base with at least one dispensing member acting upon the chambers, an outlet, and closed channels or channels with sutures arranged between following chambers and/or between the last chambers with respect to the outlet. The blister part is fastened to the blister base in such a manner that the sutures yield so that the materials may pass through. The dispensing device comprises a static mixer. By using dispensing members for the simultaneous discharge of chamber rows and the integration of a mixer, a dispensing device is realized that allows, by means of inexpensive elements, a very precise delivery of well mixed substances.
