A bottle cap with an additive supply structure, comprising a bottle cap body (1) and a storage cap (2) connected to the bottle cap body. The bottle cap body (1) comprises a first top (3) and a first outer skirt part (5) arranged at the lower end of the first top. The storage cap (2) comprises a second top (4) and a second outer skirt part (6) arranged at the lower end of the second top, and the storage cap (2) is mounted in a mounting groove (8). The second top (4), the second outer skirt part (6) and a crackable part (10) form a sealed storage space. Additives are placed in the storage cap, the storage cap is mounted in the mounting groove, sealing performance of the storage space is better, and the additives can be prevented from being affected by damp and going bad. The bottle cap body is provided with the crackable part, the crackable part can be opened only by knocking on the storage cap downwards during use, making the additives fall into a bottle body so as to be mixed with bottled contents. The bottle cap is simple in structure, low in cost, and simple and convenient to operate. Providing a thickened part ensures that the crackable part will not fall into the bottle body after the crackable part is cracked open. |
