PROBLEM TO BE SOLVED: To provide a mamilla protector which does not give pains and uncomfortable stimulation to the mamilla part of a person who performs breast-feeding by the deformation of the mamilla part without maintaining the crushed deformation of the mamilla part, reduces stimulations when abutted to a mamma, prevents a mark from remaining, and surely protects a mamilla.SOLUTION: The mamilla protector is molded entirely with a soft material, and includes: a hollow mamilla part 11 having a through-hole 11a on the distal end a body part 19 which has an enlarged diameter part 12 where the diameter of the hollow internal space is gradually enlarged continuously from the mamilla part and also has a large diameter part 13 formed by extending an enlarged inner diameter part and a mamma abutting part 15 which is a ring-like flange pat formed at the opening peripheral edge of the end of the body part. The large diameter part is provided with a narrowed part 14 formed by reducing the outer diameter and a through-hole 18 for ventilation which communicates the space and the outside.COPYRIGHT: (C)2010,JPO&INPIT【課題】乳頭部の潰れ変形が維持されることがなく、乳頭部の変形により授乳を行う者の乳頭部に痛みや不快な刺激を与えず、乳房に当接する際に刺激を低減して跡が残ることを防止し、確実に乳頭を保護できる乳頭保護具を提供すること。【解決手段】全体が柔軟な材料で成形されており、先端に貫通孔11aを備える中空の乳頭部11と、該乳頭部から連続して前記中空の内部空間を徐々に拡径した拡径部12を備えるとともに、拡大した内径部分を延長して形成した大径部13を有する胴部19と、該胴部の端部の開口周縁に形成したリング状のフランジ部である乳房当接部15とを備えており、前記大径部には、外径を縮径して形成したくびれ部14と、前記空間と外部とを連通する通気用の貫通孔18を有している乳頭保護具。【選択図】図2
