PROBLEM TO BE SOLVED: To provide a mixer which can be manufactured relatively simply and relatively inexpensively, and in which the sealing of a mixture storage chamber can be released sufficiently quickly.SOLUTION: A mixer 2 is composed of three components of a unique form having no seal member fixed by heat adhesion, which include a body 4 having a circular closing wall 10, an upper member 6 fitted to the body and covering the closing wall, and a lower member 8 fitted to the body and located below the closing wall. On the closing wall of the body, at least one breakable thin line is formed, and at least one deformation area is defined. Locked means is provided on an undersurface of the deformation area. A cylindrical wall 46 defining a mixture storage chamber 45 is formed in the upper member. The lower member has a cylindrical fitting wall 52 fitted rotatably to the body, and a support piece 54 extending radially inward from an inner peripheral surface of the fitting wall. Locking means 60 cooperating with the locked means is provided on an upper surface of the support piece.SELECTED DRAWING: Figure 1 |
