Abstract: A baby bottle for preventing the release of endocrine disrupters is disclosed. The baby bottle includes a glass vessel containing milk. A protective cover has shock absorbing members to protect the glass vessel, and includes left and right cover bodies having a fastening protrusion and a fastening hole, respectively. An air inlet packing is placed on the upper end of the glass vessel to control inflow of external air, and is coupled to a ventilation tube and a nipple. A support cap is fastened to the upper end of the protective cover in such a way that the nipple is in close contact with the upper portion of the air inlet packing, when the air inlet packing is in close contact with the glass vessel.
