Abstract
【解決手段】母乳搾乳器の母乳容器と負圧発生手段の間に取り付ける逆止弁であって、弾性材料からなり、中空円筒形状の胴部の下端側に、肉薄で、下端に向って互いの間隔が徐々に接近するように側面視断面V字状に形成された傾斜した側壁を対向して設け、それぞれその傾斜した側壁が互いに近接する直線状の下端部分の両側には、その長さ方向に肉厚のリップ部を形成して開口部とするという手段を採用した。そして、それぞれの肉厚のリップ部は、外側に凸の半割円柱形状であるという手段、上記リップ部の開口部は、無負荷状態では常に開口しているという手段を採用した。また、上記逆止弁は、シリコンゴム又はエラストマー等で形成される。
