PROBLEM TO BE SOLVED: To provide an artificial nipple, and a feeding bottle using that, in which a nipple tip can sufficiently reach a feeding hole, and can be properly crushed, in such a way that feeding movement is securely performed in the state.SOLUTION: The device includes a base part 21 as a mould of elastic material such as soft resin that is an almost conical hollow member as a whole, of which diameter is enlarged to match a mounting object, an areola part 22 formed continuous with the base part to extend with its diameter contracted gradually, and a nipple part 23 extended from the areola part, with its diameter further contracted than the areola part. A flange part 41 provided on the base part has prescribed thickness. A check valve 44 is provided on the base part to form a valve member that is totally contained in the thickness size of the flange part.COPYRIGHT: (C)2011,JPO&INPIT【課題】乳首先端部が哺乳窩に十分に到達できて、適切に押し潰されることができ、その状態で確実に哺乳運動ができるようにした、人工乳首およびこれを用いた哺乳器を提供すること。【解決手段】軟質樹脂等の弾性材料による全体が略円錐状の中空体とされた成形品であり、取り付け対象に対応して拡径されている基部21と、該基部に連続して形成されており、徐々に縮径されて延びる乳輪部22と、該乳輪部から延びており、前記乳輪部よりもさらに縮径された乳首部23とを備えており、前記基部に設けたフランジ部41が所定の厚みを有していて、該基部に設けられて前記フランジの厚み寸法内に完全に収まるように弁体を形成した逆止弁44とを備えている。【選択図】図10
