The bottle has a body (2), and a nipple (8) comprising a cover (12). A thin nozzle (10) is used for sucking by an infant. A mechanical holding unit (22) of the nipple is covered by the cover when not in use. The holding unit has hardness approximately greater than that of the nipple in order to distinguish respective mechanical behaviors of the cover and the nozzle. |
