Description
前記課題を解決するため、本発明は、突出する筒状のネック部を備え、気体又は液体を収容する中空の樹脂ライナーと、前記ネック部の径方向外側に設けられた口金部材と、前記ネック部及び前記口金部材の径方向内側に挿入された取付部材と、前記樹脂ライナー及び前記口金部材の外側を覆う補強層と、前記ネック部と前記取付部材との間に介設されたシール部材と、前記ネック部の周方向に亘って設けられた補強部材と、を有し、前記補強部材は、筒状の本体部と前記本体部から径方向内側に向けて突出する位置決め部とを備えており、前記本体部は、前記ネック部の先端から所定の距離をあけて配設され、前記位置決め部は、前記本体部において前記ネック部の基端側に形成され、前記位置決め部をブローピンの外周に当接させた状態でブロー成形して前記ブローピンと前記本体部とで囲まれた空間に樹脂を入り込ませ、前記ネック部の内部に前記補強部材を配置することを特徴とする。 In order to solve the above problems, the present invention includes a hollow resin liner that has a protruding cylindrical neck portion and accommodates a gas or a liquid, a base member provided radially outside the neck portion, and the neck. a mounting member parts and inserted in the radially inner side of the cap member, the resin liner and the reinforcement layer covering the outside of the cap member, shea Lumpur which is interposed between the mounting member and the neck portion a member, a reinforcing member provided over the circumferential direction of the neck portion, have a said reinforcing member, and a positioning portion that protrudes toward the main body portion and a cylindrical body portion radially inwardly The main body portion is disposed at a predetermined distance from the tip of the neck portion, the positioning portion is formed on the base end side of the neck portion in the main body portion, and the positioning portion is connected to the blow pin. In contact with the outer circumference By blow molding intruded resin in a space surrounded by the blow pin and the body portion, characterized by arranging the reinforcing member to the inside of the neck portion.
かかる構成によれば、内圧を受けてへたりやすいネック部の先端に補強部材を設けることにより、ネック部の強度を高めることができる。シール部材は、バルブ等の取付部材と強度が向上したネック部との間に介設されるため、樹脂ライナーに貯留された気体又は液体のリークを確実に防止することができる。また、一つのシール部材で、樹脂ライナーに貯留された気体又は液体のリークを確実に防止することができる。According to such a configuration, it is possible to increase the strength of the neck portion by providing the reinforcing member at the tip of the neck portion that is likely to sag due to internal pressure. Since the seal member is interposed between an attachment member such as a valve and a neck portion with improved strength, it is possible to reliably prevent leakage of gas or liquid stored in the resin liner. Moreover, the leak of the gas or liquid stored by the resin liner can be reliably prevented with one seal member.
また、前記シール部材は、前記ネック部の基端から先端へと向かう方向において、前記補強部材と重なる位置に設けられていることが好ましい。かかる構成によれば、ネック部のうち強度が最も高い部分と口金部材とでシール部材が挟まれるため、より確実にシールすることができる。 Moreover, it is preferable that the said sealing member is provided in the position which overlaps with the said reinforcing member in the direction which goes to the front- end | tip from the base end of the said neck part . According to such a configuration, since the seal member is sandwiched between the portion having the highest strength in the neck portion and the base member, the seal can be more reliably performed.
また、本発明は、ブローピンに補強部材を配置する配置工程と、一対の成形型の間にパリソンを供給するパリソン供給工程と、前記成形型を閉じつつこれらの成形型によって形成された空間に前記ブローピン及び前記補強部材を挿入する型締め工程と、前記ブローピンに空気を供給して前記成形型に前記パリソンを転写させるブロー工程と、を含み、前記ブローピンは、大径部と、前記大径部の先端側に設けられた小径部と、前記大径部と前記小径部によって形成された段差部とを備え、前記補強部材は、円筒状を呈する本体部と、前記本体部から径方向内側に向けて突出する位置決め部とを備えており、前記配置工程では、前記小径部に前記位置決め部を当接させるとともに前記成形型と前記補強部材との間、前記段差部と前記補強部材との間及び前記小径部と前記補強部材との間の順番で連続した空間が形成されるように配置し、前記ブロー工程では、前記連続した空間に樹脂が入り込むことにより圧力容器のネック部の内部に前記補強部材を配置することを特徴とする。 Further, the present invention provides an arrangement step of disposing a reinforcing member on the blow pin, a parison supply step of supplying a parison between a pair of molds, and a space formed by these molds while closing the mold. A mold clamping step of inserting the blow pin and the reinforcing member, and a blow step of supplying air to the blow pin to transfer the parison to the mold, wherein the blow pin has a large diameter portion and the large diameter portion A small-diameter portion provided on the distal end side, a step portion formed by the large-diameter portion and the small-diameter portion, and the reinforcing member includes a cylindrical main body portion and a radially inner side from the main body portion. and a positioning portion that protrudes toward, and in the arrangement step, between the reinforcing member and the mold is brought into contact with the positioning portion to the small diameter portion, and the reinforcing member and the stepped portion During and arranged to sequentially continuous space between is formed between the reinforcing member and the small diameter portion, the blow step, the inside of the neck of the pressure vessel by the resin from entering the continuous space The reinforcing member is arranged.
かかる方法によれば、ブローピンの段差部に補強部材を配置してブロー成形するだけでよいため、作業手間や製造コストを削減することができる。また、ブローピンに対して補強部材が位置決めされるため、ネック部に補強部材を精度よく設けることができる。According to this method, since it is only necessary to arrange the reinforcing member at the step portion of the blow pin and perform blow molding, it is possible to reduce labor and manufacturing cost. Further, since the reinforcing member is positioned with respect to the blow pin, the reinforcing member can be provided on the neck portion with high accuracy.
