ABSTRACT:
A mixing capsule for mixing a first material with a second material, and in particular, a capsule in which the materials are kept separated and brought together only at the time they are to be mixed. The capsule is characterized by a pierceable partition which separates the materials to be mixed, a projection for piercing the partition and two grooves and a ridge. One of the grooves cooperates with the ridge so as to maintain the projection away from the pierceable partition during storage and transport. The other groove cooperates with the ridge so as to hold the mixing capsule together and prevent leakage once the partition is pierced.
