ABSTRACT:
The gas-venting groove or grooves are formed, while leaving a part of the thread ridge up to a certain height, as the vertical degassing paths in the thread ridge carved on the outer surface of the round neck wall and the entire neck is whitened by the thermal crystallization. This thermal crystallization is conducted under the condition that the neck is prevented from undesired deformation caused by uneven resin flow state. Thus, the object of this invention is to provide a highly safe neck that can be used widely in the field of heat-resistant containers, pressure-tight containers, and heat-resistant and pressure-tight containers.
