PROBLEM TO BE SOLVED: To provide an expired air sampling vessel that even a person whose expiration power is weak can surely use and with which an expired air sample can be measured accurately by preventing external air that an examinee breathes in through deep breathing from being sampled as it is.SOLUTION: An expired air sampling vessel 1 comprises: a vessel body 3 which includes a mouth part 3a in an upper end and a lower end of which is closed with a bottom part 3b to form an expired air storage space M inside and a base cap 11 which includes a top wall 5 covering the upper end opening of the mouth part 3a of the vessel body 3 and a surrounding wall 7 which is drooped from an outer circumferential edge of the top wall 5 and surrounds the mouth part 3a, and forms a through-hole 9 communicated to the storage space M on the top wall 5. On a rear side of the top wall 5, a pipe 13 is provided perpendicularly which is communicated with the through-hole 9 and the distal end of which directs the bottom part 3b. On the top wall 5, an opening 14 is formed which discharges gas extruded from the storage space M with expired air that flows in through the through-hole 9 and the pipe 13.COPYRIGHT: (C)2013,JPO&INPIT【課題】吹き込み力の弱い者でも確実に使用することができ、かつ、被験者が深呼吸により吸い込んだ外気がそのまま採取されるのを防止して呼気試料の正確な測定を可能とする呼気採取容器を提供する。【解決手段】呼気採取容器1は、上端に口部3aを有するとともに下端を底部3bで閉塞して内側に呼気の収容空間Mを形成する容器本体3と、容器本体3の口部3aの上端開口を覆う天壁5および該天壁5の外周縁より垂下して口部3aを取り囲む周壁7を有し、天壁5に収容空間Mにつながる貫通開孔9を形成してなるベースキャップ11と、を備え、天壁5の裏面に、貫通開孔9と連通し先端が底部3bを指向するパイプ13を垂設するとともに、該天壁5に、貫通開孔9およびパイプ13を通って流入する呼気によって収容空間Mから押し出される気体を排出させる開孔14を形成してなるものである。【選択図】図1
