Zusammenfassung: | To provide a vent tool generating a small gap between a nozzle tip of a suction machine and an abutting surface onto which the nozzle tip abuts.SOLUTION: A vent tool comprises a body part 1 anchored to an insertion hole provided at a storage bag and an adapter part 2 fitted to the body part 1. The body part 1 comprises a base part 4, a valve body 3 stored in the base part 4 and a lid part 5 fitted to the base part 4. The diameter of an outer periphery of the adapter part 2 is substantially identical with a diameter of a flange part 4a and is in an annular shape. The adapter part 2 is pushed until a lower bottom surface of the adapter part 2 abuts onto a surface 4b of the flange part 4a after inserted into the lid part 5 of the body part 1 anchored to the storage bag in a state where a central hole 2f is expanded. Air in the storage bag is exhausted by pushing the tip of the nozzle of a suction machine to a top surface 2a of the adapter part 2 to activate the suction machine.SELECTED DRAWING: Figure 1
【課題】吸引機のノズル先端とノズル先端が当接する当接面との間に、僅かな隙間を生じさせる排気具を提供する。【解決手段】排気具は収納袋に設けた挿入孔に固着する本体部1と、この本体部1に取り付けるアダプタ部2とから構成され、本体部1は、基部4と、この基部4内に収納する弁体3と、基部4に取り付ける蓋部5とから構成されている。アダプタ部2の外周の直径は、フランジ部4aの直径と略一致し、環状体をしている。アダプタ部2を、中央孔2fを拡開した状態で、収納袋に固着した本体部1の蓋部5に挿入した後に、アダプタ部2の下底面がフランジ部4aの表面4bに当接するまで押し込む。吸引機のノズルの先端をアダプタ部2の頂面2aに押し当てて、吸引機を起動させることで収納袋内の空気の排気を行う。【選択図】図1 |
