有底筒状に形成された金属製の缶体の開口部を縮径してなる口金部の上部外周にねじ部が設けられるとともに、前記ねじ部よりも下方にキャップ本体下部を巻き締めるための膨出部が形成され、前記口金部の先端部に外側に折り曲げられて形成されたカール部が設けられたボトル缶体の製造方法であって、  A screw portion is provided on the outer periphery of the upper portion of the base portion formed by reducing the diameter of the opening portion of the metal can body formed in a bottomed cylindrical shape, and for tightening the lower portion of the cap body below the screw portion. A bulging portion is formed, and a method of manufacturing a bottle can body provided with a curled portion formed by bending outward at a tip portion of the base portion,
前記開口部を縮径して口金部を形成した後、その口金部の開口端から所定距離分だけ再び拡径して拡径部を形成し、  After forming the base part by reducing the diameter of the opening, the diameter is increased again by a predetermined distance from the opening end of the base part to form an enlarged part,
前記ねじ部は、前記拡径部が形成された後、ねじを形成する部分を縮径し、その縮径された部分にねじ切り加工することによって形成され、  The threaded portion is formed by reducing the diameter of the portion that forms the screw after the diameter-expanded portion is formed, and threading the reduced diameter portion,
前記膨出部は、前記ねじ部を形成する際に縮径されずに残った拡径部分によって形成されることを特徴とするボトル缶体の製造方法。  The method of manufacturing a bottle can body, wherein the bulging portion is formed by an enlarged diameter portion that remains without being reduced in diameter when the screw portion is formed.
