The present invention relates to a bottle cap having a top function. The conventional bottle cap having a top function was made to rotate with the top part of its dome shape contacting the floor when the user rotates it by holding the middle part which is thicker than the entrance. However, the conventional bottle cap requires to additionally form the middle part and an additional forming has to be done on the top part of the dome shape with its inside closed. When the inside of the dome shape is closed, the material cost is increased for the materials occupying the thickness, and the entire manufacturing cost is also increased. The external shape is also greatly changed making harmony difficult with the conventional bottle formed. The present invention adds a top function while not greatly changing the external shape of the conventionally provided bottle cap to harmonize with the provided bottle. When the bottle cap is used as a top, the user is allowed to cut a toothpick, a matchstick, or a straw, which are easy to grip, to insert them into the bottle cap, and to hold it to rotate or is allowed to hold the handle formed into one body with the inside of the bottle cap and rotate it by hand. Thus, a great rotary force is conveyed to the bottle cap, and the rotating time is increased over that of the conventional bottle cap to increase the interest in playing with the top. And, the user can play a game wherein the person who is directed by the arrow placed on the bottom surface of the bottle cap selectively conducts a motion instructed as a penalty. |
