To prevent increase in the number of assembly steps are failure due to interpose a urethane plate between the core member and the container (interior material), the increase in waste. A container 2 comprising, a cap 5 and the container body 3 of the tubular longitudinal end face is open, opening and closing by detaching the opening 4 of the container body, is housed in a container, the longitudinal end face at least In the sperm collecting apparatus having a, a core member 10 of the gel-like resin having an insertion cavity 12 extending inward from the insertion slot 11, the core member, the core body 50 provided with an insertion cavity and the insertion opening, By wherein the ribs 51 of the plurality of intersecting each other and protrude from the outer surface of the core body, the outer edge of each rib is in contact with the container body inner wall, and a core body outer surface, and a plurality of ribs, and the I will form a closed space S between the inner wall of the container body.容器とコア部材(内装材)との間にウレタン板を介在させることによる不具合である組立工数の増大、ゴミの増大を防止する。少なくとも長手方向一端面が開口した筒状の容器本体3と、該容器本体の開口部4に着脱して開閉するキャップ5と、から成る容器2と、容器内に収容され、長手方向一端面の挿入口11から内部に延びる挿入空所12を有したゲル状樹脂製のコア部材10と、を備えた精子採取装置において、コア部材は、挿入口と挿入空所を備えたコア本体50と、該コア本体の外面から突設して互いに交差する複数のリブ51と、を備え、各リブの外側端縁が前記容器本体内壁に接触することにより、コア本体外面と、複数のリブと、前記容器本体内壁との間で密閉空所Sを形成する。
