PROBLEM TO BE SOLVED: To provide a dispensing container capable of preventing a microorganism from entering a content liquid storing part, and having a simple structure and being compact.SOLUTION: The dispensing container 1 includes: a double container 9 consisting of an external layer body 3 and an internal layer body 5, and forming an open air introducing hole 7 for introducing the open air between the external layer body 3 and the internal layer body 5 each other on the mouth part 3a of the external layer body 3 and a plug body 11 assembled on the mouth part 9a of the double container 9 and for dispensing the content liquid in the internal layer body 5. On the plug body 11, a valve member integrally has a dispensing valve part 35 and an air suction valve part 37 and comprising an elastic material is provided. The dispensing valve part is formed of a dispensing hole 31 for dispensing the content liquid stored in the internal layer body 5, and an air suction hole 33 connected with the open air introducing hole 7, the dispensing hole 31 is enclosed and meanwhile, is elastically deformed by the liquid pressure to be opened by pressing. The air suction valve part encloses the air suction hole 33, and meanwhile, it is elastically deformed by the negative pressure in the external layer body 3 with the volume reduction of the internal layer body 5 when the content liquid is dispensed to open the air suction hole 33.COPYRIGHT: (C)2013,JPO&INPIT【課題】内容液収容部への微生物の侵入を防止することができ、構造が簡単でコンパクトな吐出容器を提案する。【解決手段】吐出容器1は、外層体3と内層体5とからなり、外層体3の口部3aに外層体3および内層体5相互間に外気を導入するための外気導入孔7を形成してなる二重容器9と、該二重容器9の口部9aに組み付けられ、内層体5内の内容液を吐出する栓体11とを備える。栓体11には、内層体5内に収容された内容液を吐出するための吐出孔31と、外気導入孔7につながる吸気孔33とが形成されるとともに、吐出孔31を閉塞する一方、液圧で弾性変形して押し開かれる吐出弁部35と、吸気孔33を閉塞する一方、内容液が吐出した際の内層体5の減容に伴う外層体3内の負圧により弾性変形して吸気孔33を開放する吸気弁部37とを一体に有する、弾性材からなる弁部材が設けられている。【選択図】図1
