< Topic >Offer of the collection container in order to treat the blood waste safely.SolutionsThe container itself having opening 23 2, the cover in full circuit of the open end of the container itself lap the wall 25 in cover 3 the flat part 31 which covers the whole surface of opening 23, flange 24 and lap the annular section 32 which covers the wall 25, injector insertion opening 33, facilities the blood waste inside container 1 from injector insertion opening 33 it starts us to be constituted from the absorption pad 4 which is laid out inside 3 which closes the opening and container 1, form just in flange, 24 and the rim be done on rear side of flat part, 31 leaping to outside the container and it starts neutron leakage, the function which is preventedWhen it has the sponge component 5 which, it possesses pushes in cover 3 together in container itself 2, lap annular pawl 34 the person in charge stopping and cover 3 is locked to container itself 2 in bottom full circuit of the wall 25 by the restoring force of aforementioned annular public side. When the injector can be flared with the cutting eye 35 of the interpose and sponge component 34 to injector insertion opening 33, the injector is surpassed on the one hand, injector insertion opening 33 is closed with the restoring force of sponge component 34.< Choice figure >Drawing 1【課題】血液廃棄物を安全に処理するための捕集容器の提供。【解決手段】開口部23を備える容器本体2、開口部を塞ぐ蓋3、容器1内に配置される吸収パッド4から構成されており、容器本体の開放端の全周にはフランジ24とその外周に周壁25が一体成形され、蓋3には開口部23の全面を覆う平坦部31、フランジ24及び周壁25を覆う環状部32、注射器挿入口33、平坦部31の背面側に貼設され、容器1内の血液廃棄物が注射器挿入口33から容器外へ跳ね出したりや漏れ出したりを防止する機能を有する海綿部材5を備え、容器本体2に蓋3を合わせて押し込むと、前記環状部外側の復元力により周壁25の下端全周に環状爪34が係止し、蓋3が容器本体2に固定される。注射器を注射器挿入口33へ挿し込むと、海綿部材34の切り目35によって押し広げられ、一方注射器を抜き去ると海綿部材34の復元力により注射器挿入口33を塞ぐ。【選択図】図1
