The first chamber and the second chamber are communicated by insertion of a straw, and respective contents filled in the first chamber and the second chamber are mixed. The first container and the second container are connected in a state that a first wall and a second wall face to each other. The second container has a straw insertion part 230a. Before a tip end of the straw reaches an inner wall surface of the first chamber by inserting the straw from the straw insertion part, an opening area formed on the first wall becomes larger than a cross sectional area of the straw at a height same as that of the first wall, and an opening area of the second wall becomes larger than a cross sectional area of the straw at a height same as that of the second wall. |
