Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a pressure container having high connection strength between a liner body and a mouthpiece flange portion, and having superior gas sealing performed on an interface therebetween.SOLUTION: A pressure container 10 has a liner body 11, an FRP layer 12, a mouthpiece body 30 having a cylindrical portion 32 and a metallic flange portion 33, and made of metal, and a mouthpiece 20 covering at least an outer peripheral face of the cylindrical portion 32 and the entire metallic flange portion 33 of the mouthpiece body 30, having an annular resin flange portion 42 projecting radially outward from an end of the metallic flange portion 33, attached to an inner side face of the liner body 11, and having a mold body 40 made of a synthetic resin. A surface attached to the liner body 11, of the mouthpiece 20 is composed of the mold body 40, an outer peripheral end face 43 of the resin flange portion 42 is disposed radially outward end portion of the resin flange portion 42, and the liner body 11 continuously covers an upper side face and a part of the outer peripheral end face 43.
【課題】ライナ体と口金フランジ部との結合強度が高く、両者の界面におけるガスシール性能に優れた圧力容器を提供することを目的とする。【解決手段】ライナ体11と、FRP層12と、筒状部32と金属フランジ部33とを有し、かつ金属で形成される口金本体30と、口金本体30のうち少なくとも筒状部32の外周面及び金属フランジ部33全体を覆い、金属フランジ部33の端から径方向外向きに張り出す環状の樹脂フランジ部42を有し、ライナ体11の内側面と被着し、合成樹脂で形成されるモールド体40とを有する口金20と、を備え、口金20におけるライナ体11と被着される面は、モールド体40で構成されており、樹脂フランジ部42の外周端面43は、樹脂フランジ部42の径方向外向きの端部に設けられており、ライナ体11が前記上側面、及び外周端面43の一部を連続して覆っている圧力容器10。【選択図】図2 |
