A heterogeneous material-containing bottle cap coupled to a container in a content discharge direction comprises a body assembled to a mouth of the container; a storage space coupled within the body; a receptacle having an opening; a spout assembled onto an upper body mouth having the receptacle; a seal formed on the lower portion of the spout for sealing the opening of the receptacle; and an upper cap having an upper spout engaging part is engaged with and assembled onto an upper side engaging part at the top of the spout. In such a bottle cap with the above configuration, when the upper cap is open, the spout ascends and the seal being sealed in the opening is pushed upwards such that the opening of the receptacle is open. Further, an actuation part with a dolphin formed in the space is assembled onto the bottom of the receptacle. As such, when the bottle cap with the actuation part is assembled onto the bottle neck, it stops temporarily, as opposed to the bottle neck. Under such circumstance, the body and the receptacle descend together, the dolphin of the actuation part pushes the seal that is mounted in the opening of the receptacle upward, and heterogeneous materials kept in the storage space of the receptacle are then dropped and mixed through the opening of the receptacle. |
