The spiral cylinder B5 is configured to rotate at a reduced speed with respect to the rotation of the cylindrical substrate B4.

  A case where the mixing apparatus configured as described above is used will be described. FIG. 1 shows a state in which the two-chamber container A is mounted on the mixing device B. From this state, when the cylindrical base B4 is rotated relative to the pedestal B1, the second gears B3 are rotated clockwise. Revolve. At that time, the first gear member B2 is rotated clockwise by the first gear 37 meshed with the second gear B3. The first gear member B2 rotates until its ratchet pawl 38 comes into contact with the vertical surface 32b of the ratchet projection 32. When these contact, the rotation stops, and the second gear B3 starts rotating while revolving. If the ratchet pawl 38 and the vertical surface 32b of the ratchet projection 32 are in contact with each other from the beginning, the first gear member B2 does not rotate from the beginning, and only the second gear B3 rotates clockwise. Revolve around.

  As the second gears B3 rotate (rotate), the third cylinder 73 meshed with them rotates the helical cylinder B5 in the clockwise direction. The clockwise rotation of the helical cylinder B5 is slower than the clockwise rotation of the cylindrical base B4, and as a result, the sliding protrusions 78 on the inclined surface 71 are guided by the vertical grooves 41 and are lifted.

Further, when the pressing body B6 is raised, as shown in FIG. 13, the first movable wall A6 rises until it comes into contact with the lower surface of the second movable wall A7, and the contents in the first accommodation chamber R1 become the second accommodation chamber R2. And mix thoroughly with the contents in the second storage chamber R2.

  Thereafter, when the cylindrical base B4 is further rotated clockwise with respect to the pedestal B1, the sliding protrusions 78 are all lifted up the inclined surface 71, and then are guided by the vertical surface 75 so that the pressing body B6 is caused by its own weight. Move down and return to the original state. Next, the two-chamber container A is rotated by a predetermined angle with respect to the cylindrical base B4 so that each engaging projection 14 is pivoted to a lower position of each insertion passage and then lifted upward. Can be easily removed from the mixing device B.

  When installing a new two-chamber container A, each engaging projection 14 is inserted through the insertion passage, the two-chamber container A is pushed in, and the two-chamber container A is rotated with respect to the mixing device B at the lowest position. Thus, the engaging protrusion 14 may be engaged with the downward stepped portion 66 between the locking protrusion 67 and the overpass protrusion 69.

  In addition, although the material which forms each said member is not specifically limited, a synthetic resin can be employ | adopted preferably.
