Description
本発明は、飲料用等のキャップが螺着されるねじを有する容器を密封するライナ付キャップの製造方法に関する。 The present invention relates to the production how the liner with the cap to seal the container with a screw cap or the like beverage is screwed.
本発明は、このような事情に鑑みてなされたものであって、ライナの材料使用率を高めることができ、容器開栓時のトルクを比較的低い状態で維持できるとともに、開栓前は良好に密封状態を維持することができるライナ付キャップの製造方法を提供することを目的とする。 The present invention has been made in view of such circumstances, can increase the material usage rate of the liner, can maintain a relatively low torque when opening the container, and is good before opening and to provide a manufacturing how the cap with liner can maintain the sealed state.
本発明のライナ付キャップの製造方法は、天面部と該天面部の周縁から略垂下されてなる円筒部とを備えるキャップ本体と、前記天面部の内面に非接着状態に設けられたライナとを有し、容器を密栓可能なライナ付キャップを製造する方法であって、アルミニウム又はアルミニウム合金の板材をカップ状に打抜いてキャップ本体を成形するキャップ本体成形工程と、前記キャップ本体の天面部と摺動する摺動層を該天面部内面に樹脂のモールド成形により形成する摺動層成形工程と、前記円筒部の前記天面部近傍に半径方向内方に突出して前記摺動層を係止するフック部を形成するフック部形成工程と、前記フック部を形成した後に、前記摺動層に積層され該摺動層よりも軟質で外径が小さく前記容器と接触する密封層を樹脂のモールド成形により形成して、前記摺動層と前記密封層とからなる前記ライナを形成する密封層成形工程とを備え、前記摺動層成形工程よりも前に前記天面部の内面に前記摺動層の接着防止措置を施す接着防止措置工程を有することを特徴とする。 A method of manufacturing a cap with a liner according to the present invention comprises: a cap body including a top surface portion and a cylindrical portion substantially suspended from the periphery of the top surface portion; and a liner provided in an unbonded state on the inner surface of the top surface portion. A method of manufacturing a cap with a liner capable of sealing a container, and forming a cap body by punching a plate of aluminum or aluminum alloy into a cup shape; and a top surface portion of the cap body; engaging a sliding layer forming step of the sliding layer is formed by molding a resin in the top panel face the inner surface, the sliding layer protrudes above the top surface portion radius inward in the vicinity of the cylindrical portion which slides a hook portion forming step of forming a full-click portions you, after forming the hook portion, the sealing layer outer diameter is in contact with reduced the vessel is softer than the sliding Doso laminated on the sliding layer Resin molding A sealing layer forming step for forming the liner composed of the sliding layer and the sealing layer, wherein the sliding layer is formed on the inner surface of the top surface portion before the sliding layer forming step. It has the adhesion prevention measure process which performs an adhesion prevention measure, It is characterized by the above-mentioned.
本発明のライナ付キャップの製造方法は、天面部と該天面部の周縁から略垂下されてなる円筒部とを備えるキャップ本体と、前記天面部の内面に非接着状態に設けられたライナとを有し、容器を密栓可能なライナ付キャップを製造する方法であって、アルミニウム又はアルミニウム合金の板材をカップ状に打抜いてキャップ本体を成形するキャップ本体成形工程と、前記キャップ本体の天面部と摺動する摺動層を該天面部内面に樹脂のモールド成形により形成する摺動層成形工程と、前記摺動層に積層され該摺動層よりも軟質で外径が小さく前記容器と接触する密封層を樹脂のモールド成形により形成して、前記摺動層と前記密封層とからなる前記ライナを形成する密封層成形工程と、前記ライナを形成した後に、前記円筒部の前記天面部近傍に半径方向内方に突出して前記摺動層を係止するフック部を形成するフック部形成工程とを備え、前記摺動層成形工程よりも前に前記天面部の内面に前記摺動層の接着防止措置を施す接着防止措置工程を有することを特徴とする。 A method of manufacturing a cap with a liner according to the present invention comprises: a cap body including a top surface portion and a cylindrical portion substantially suspended from the periphery of the top surface portion; and a liner provided in an unbonded state on the inner surface of the top surface portion. A method of manufacturing a cap with a liner capable of sealing a container, and forming a cap body by punching a plate of aluminum or aluminum alloy into a cup shape; and a top surface portion of the cap body; A sliding layer forming step in which a sliding sliding layer is formed on the inner surface of the top surface portion by resin molding, and is laminated on the sliding layer and is softer and smaller in outer diameter than the sliding layer and is in contact with the container. Forming a sealing layer by resin molding to form the liner composed of the sliding layer and the sealing layer; and forming the liner, and then forming the liner and then close to the top surface portion of the cylindrical portion. Projects half radially inward and a hook portion forming step of forming a full-click unit that abolish engaging said sliding layer to said the inner surface of the top surface portion before the slide layer forming step It has the adhesion prevention measure process which performs the adhesion prevention measure of a sliding layer, It is characterized by the above-mentioned.
