VALVE-INTEGRATING CONTAINER, LIQUID WITHDRAWING DEVICE EQUIPPED WITH THE SAME, AND METHOD FOR MANUFACTURING VALVE-INTEGRATING CONTAINER

摘要

The valve-integrating container (100) includes a container body (10) and a valve mechanism (20) switching whether a liquid stored in the container body (10) is allowed to flow out. The valve mechanism (20) has a spring (21), a spring supporting part (22), and a valve plug (23). The spring supporting part (22) has a liquid flow channel (22a) formed in a cylindrical shape extending along the axis X, a lower end portion (22b) mounted to an internal threads of a reduced-diameter portion (12), an upper end portion (22c) projecting toward the enlarged-diameter portion (11), and a guide groove (22d) formed on a lower end side outer circumferential surface for guiding a liquid stored in a connecting portion (13) downwardly. The valve plug (23) has on its outer circumferential surface a guide groove (23a) guiding the liquid guided by the guide groove (22d) downwardly to an opening portion (12a).
