However, because the spring force and atmospheric pressure cannot give sufficie...
Fix the assembled bottle or jar on the special fixture of the torque meter, rotate the cover by hand, and take the displayed data on the torque meter as the standard to achieve the required test force; the corresponding torque value of the thread diameter should conform to the normative appendix Table of rules. There is no slipping in the vacuum bottle and lotion bottle where the screw teeth are subjected to the specified rotational torque. Low temperature test requirements: Vacuum bottles and l...
