ABSTRACT:
A chemicals mixing container (1), which allows two kinds of chemicals, a liquid material (2) and a powder material (4), to be stored therein in isolation from each other and which allows the liquid material (2) and the powder material (4) to be mixed together. The mixing container includes: a first cylinder (6); a first piston (7) which is fitted in the first cylinder (6) to define a first internal space (3); a second cylinder (8) which is connected to the first cylinder (6) or the first piston (7) so as to be rotationally slidable thereon; and a second piston (9) which is fitted in the second cylinder to define a second internal space (5). The second cylinder (8) and the first cylinder (6) or the first piston (7) to which the second cylinder (8) is connected have communicating holes (13, 14) formed in their mutual sliding surfaces at positions, respectively, eccentric relative to a rotation axis X. The first internal space (3) and the second internal space (5) are communicated with or isolated from each other depending on a rotational sliding angle between the second cylinder (8) and the first cylinder (6) or the first piston (7) to which the second cylinder (8) is connected.
