PROBLEM TO BE SOLVED: To provide a hot-water bottle which is not less likely to induce a low-temperature burn by the morphological improvement of the shape, structure, etc. of a hot-water bottle body.SOLUTION: This invention relates to a plastic hot-water bottle which includes a nearly disk-shaped hot-water bottle body and is constituted so that a hot water pouring port for pouring hot water into the inside thereof is provided in the center of one surface of the hot-water bottle body. On the inner side of ridgelines surrounding the hot water pouring port of the one surface of the hot-water bottle body 11, a recessed part 13 is formed so that the hot water pouring port rises from the recessed part. Furthermore, in order that a part of the body such as a foot, which is placed on the hot-water bottle body, slips down, a portion on the outer side of the ridgelines of the outer periphery of the recessed part of the one surface surrounding the hot water pouring port is formed to have a gentle curved surface 15. Also in the center of the other surface of the hot-water bottle body, a recessed part surrounded by the ridgelines is formed, and the outer side of the ridgelines of the outer periphery of the recessed part of the other surface is formed to have the gentle curved surface.COPYRIGHT: (C)2011,JPO&INPIT【課題】湯たんぽ本体の形状、構造等の形態的な改良によって、低温やけどを誘発し難い湯たんぽを実現する。【解決手段】ほぼ円盤型の湯たんぽ本体を有し、その内部に湯を注入する注湯口を湯たんぽ本体の一面の中央部に設けた構成を有するプラスチック製の湯たんぽであって、湯たんぽ本体11の一面の注湯口を取り囲む稜線の内側に凹部13を形成し、その凹部から注湯口が立ち上がるように構成し、かつ、湯たんぽ本体に足など身体の一部を載せたときに滑り落ちるように注湯口を取り囲む一面の凹部外周の稜線から外方を滑らかな曲面15で構成し、また、湯たんぽ本体の他面の中央部にも稜線で囲まれた凹部を形成するとともに、他面の凹部外周の稜線から外方を滑らかな曲面で構成する。【選択図】図1
