Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 ^ 8929 A7 _____B7__ V. State at the time of the invention description (9). Fig. 6A shows a state where the cap of Example 2 is completely attached to the head of the bottle mouth. Fig. 7A shows a state in which the cap of the comparison side 1 is completely attached to the neck and neck of the bottle. Fig. 5B shows a state in which the cap of the embodiment is mounted halfway through the neck and neck of the bottle. Fig. 6B does not show the embodiment. The cap of Example 2 is mounted halfway through the mouth and neck of the bottle. Fig. 7B shows a state in which the cap of Comparative Example 1 is mounted halfway through the neck and neck of the bottle. When these drawings are compared and examined, Examples 1 and 2 are compared with Comparative Example 1 in that the contact area of the bottle lip portion 211 of the ring-shaped sealing portion 140 is large and tightly sealed, and it can be judged that the bottle has good sealing performance. Alas, the ring-shaped seal is quite effective in contact with the outer surface of the bottle lip, and it is very effective for the inside of the mouth of an extended blow-molded bottle made of polyethylene terephthalate. Next, for Example 1, Example 2, Example 3, and Comparative Example 1, the torque when the cap was plugged into the neck and neck of the bottle was measured. FIG. 8 is a graph showing the relationship between the winding angle and the torque. The lines L1, L2, L3, and L4 in Fig. 8 represent the characteristics of Example 1, Example 2, Implementation 'Example 3, and Comparative Example 1 obtained experimentally, respectively. Looking at FIG. 8, Comparative Example 1 and Example 1, Example 2 and Example 3 have a larger angle of torque generation than ®. In this case, when the cap is turned in the unloading direction, the comparative example uses the earliest torque, which means that the angle becomes 0 (small release seal angle). In addition, Binshi Example 1, Nutrient Example 2 and Example 3 have a larger release sealing angle than Comparative Example 1, and the torque shows that the sealability is good. That is, in Example 3, when the cap is rotated in the unloading direction, although the attenuation rate of the torque is reduced halfway, the moment becomes 0 earlier than in Examples 1 and 2. This is because the contents of Example 3 are supposed to be pressurized contents such as carbonated beverages due to the release property. -1 The size of this paper is applicable to the Chinese National Standard (CNS) A4 specification mo X 297 mm.
