A mixing applicator for mixing a fluid substance with a solid substance to obtain a resulting substance having a desired consistency, comprises: two valves slidably displaceable within a hollow elongated barrel and sequentially arranged along a longitudinal axis, the valves having a third cross-sectional shape being complementary to a first cross sectional shape, thereby providing fluid-tight engagement within the first cross-sectional shape, the third cross-sectional shape being mismatched with a second cross-sectional shape to form a mismatch zone along a length of a chamber, the mismatch zone allowing fluid flow around the valves, thereby to allow the two valves to effect mixing of the fluid substance with the solid substance and subsequently to remove excess fluid to obtain the resulting substance having the desired consistency. |

1. A mixing applicator for mixing a fluid substance with a solid substance to obtain a resulting substance having a desired consistency, the applicator comprising:
a hollow elongated barrel having distal and proximal openings, the elongated barrel having a first cross sectional shape along a first proximal portion of the elongated barrel defining a first chamber, and a different second cross sectional shape along a second distal portion of the elongated barrel defining a second chamber, the second cross sectional shape extending from the distal end of the first portion to the distal opening of the hollow elongated barrel; a first and a second valve both slidably displaceable within the hollow elongated barrel and sequentially arranged along a longitudinal axis of the barrel, said solid substance and said fluid substance, being separately held on either side of said second valve, the first and second valves having a third cross-sectional shape being complementary to said first cross sectional shape, thereby providing fluid-tight engagement within said first cross-sectional shape, said third cross-sectional shape being mismatched with said second cross-sectional shape to form a mismatch zone along a length of said second chamber, said mismatch zone allowing fluid flow around the valves, said slidable displacement of said valves being configured with a length to locate both of said solid substance, said second valve and said fluid substance together in said mismatch zone, thereby to allow said first and second valves to effect mixing of said fluid substance with said solid substance and subsequently to remove excess fluid to obtain said resulting substance having said desired consistency. |
