PROBLEM TO BE SOLVED: To provide an infant-feeding bottle capable of being compact by being sanitarily folded.SOLUTION: An infant-feeding bottle is made of plastic, has an upper wall 2 having a cylindrical port 1, a bottom face wall 3, and a peripheral wall 4, and forms a recessed groove 7 along a scheduled folding line for folding so as to bring a front wall part inner surface and a rear wall part inner surface of the peripheral wall 4 into contact with each other. The recessed groove 7 is provided in an external surface 8. With this, the infant-feeding bottle can be folded and become compact, and be sanitarily expanded without touching the inner surface, and facilitates dissolving entire powdered milk without nondissolution.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2019,JPO&INPIT【課題】衛生的に折畳んでコンパクトにし得る哺乳瓶を提供する。【解決手段】プラスチック製であって、円筒状口部1を有する上壁2と、底面壁3と、周囲壁4とを、有し、周囲壁4の前壁部内面と後壁部内面が接するように折畳むための予定折れ線に沿って、凹溝7を形成する。凹溝7は、外面8に設けられている。これにより、折畳んでコンパクトにし得るとともに、内面に触れることなく衛生的に展開することができ、粉ミルクの溶け残しがなく、全部を容易に溶かすことが可能な哺乳瓶が提供できる。【選択図】図2
