PURPOSE: To make it possible to mix plural components with high accuracy by disposing a partitioning structure between a first chamber and a second chamber and providing this partitioning structure with a valve for starting a mixing step. CONSTITUTION: When an actuating member 58 is moved by the operation of an outer ring 60, hand or equivalent means, spikes 68 perforate a sheet 53 and the semi-conical outside surfaces thereof engage the complementary semi- conical recessed parts 69 formed within the inside surface of a vessel 50. The sheet 53 is clamped within the perforated region between the outside surface of the spikes 68 and the recessed parts 69 by this engagement, by which the holes formed in the sheet are opened and maintained and, simultaneously, partial loosening of the sheet and intrusion into the mixing material are prevented. As a result, the mixing may be efficiently executed. |
