Abstract:
1. A cap containing a secondary material, comprising: a fixing member fixed on a container, the fixing member having a hollow main body and a supporting tube extending downward from an inner surface of the hollow main body, the supporting tube having a material exhausting portion and a seal member formed on the lower end of the supporting tube; a movable member threadably coupled to the fixing member, the movable member having a main body coupled on the main body of the fixing member and a tube extending downward from the main body to define a storage chamber for secondary material, the tube being provided with an opened lower end through which the secondary material is filled in the storage chamber, the opened lower end of the tube being tightly interlocked with the seal member formed on the supporting tube of the fixing member after the secondary material is filled in the storage chamber and the movable member is coupled to the fixing member and being released from the seal member so that the secondary material is mixed with a primary material contained in the container by being exhausted into the container through the material exhausting portion formed on the supporting tube of the fixing member when the movable member is moved relative to the fixing member thereby removing the seal and providing an opening between the opened lower end of the tube and the seal member thereby releasing the secondary material from the storage chamber into the primary material; and a stirring projection pin formed on an eccentric portion of the seal member and is configured to stir the secondary material when the movable member is removed from the fixing member, whereby rotation of the moveable member relative to the fixing member causes rotation of the secondary material relative to the stirring projection pin thereby causing stirring of the secondary material.
