A bottle, in particular a baby's bottle, having a bottle jacket that is open at both ends. A base cap that is equipped with an air intake valve is fixed in one base end region of the bottle jacket and a teat is fixed in the opposite teat end region. The teat has a shaft and a nipple connected to the shaft by a lip contact region. The bottle jacket has an essentially conical form that widens from the teat end region to the base end region and the wall thickness of the shaft of the teat is greater than the wall thickness of the teat in the lip contact region and of the nipple. The bottle jacket is injection-molded from a polyolefin, in particular polypropylene.
