A method of coupling a container body (2) and a cover member (3) in a capsular container (1) includes a filling step for filling liquid medicine, powdered medicine, or granular medicine in the container body (2), and a fitting step for fitting the container body (2) to the cover member (3) under an atmosphere at a negative pressure which is lower than atmospheric pressure. Consequently, the pressure inside the joined container (1) does not exceed atmospheric pressure, the filling (37) which fills the inside of the container (1) can be prevented from leaking out between the container body (2) and the cover (3), and it is also possible to prevent bending of the container (1) which starts from the weak portion of the container (1).本發明之課題係為提供一種在把液體、粉體或粒體裝入容器本體後,在裝上蓋體時,可抑制內壓上昇之蓋體的結合方法。本發明之解決手段為:在低於大氣壓的負壓狀態下,結合容器本體2與蓋體3。2...容器本體3...蓋體4...容器本體承接部5...凹部6...蓋體承接部7...凹部8...管部9...下面10...推昇銷11...銷孔12...孔
