The invention discloses a bottle structure, which comprises a nipple, a screw cap and a bottle body. The bottom end of the bottle body is provided with a base, and the bottom of the base is an arc end, and the base is provided with a counterweight unit. Thus, when the bottle body is under the force, it will swing, and when the force is counteracted, it will return to the upright state.本創作揭露一種奶瓶構造，其包含奶嘴、旋蓋及瓶體所構成。該瓶體的底端設有一底座，而底座的底部為圓弧端，且底座內設有配重單元者。藉此，當瓶體受力時擺動，力量抵消時則回復為直立狀態。
