FIG. 5A shows a state in which the cap of Example 1 is completely attached to the mouth and neck of the bottle.
FIG. 7A shows a state when the cap of Example 2 is completely attached to the mouth and neck of the bottle, and FIG.
Shows a state in which the cap of Comparative Example 1 is completely attached to the mouth and neck of the bottle. Then, FIG.
FIG. 6B shows a state in which the cap of Example 1 is being attached to the mouth and neck of the bottle, and FIG. 6B shows a state in which the cap of Example 2 is being attached to the mouth and neck of the bottle. FIG. 7 (b) shows a state in which the cap of Comparative Example 1 is being attached to the mouth and neck of the bottle. Comparing and examining these figures, in Examples 1 and 2, the contact area of the ring-shaped sealing portion (140) with the bottle mouth (211) is large and firmly adhered, and the sealing of the bottle is large. Can be determined to be good. In addition, since the ring-shaped sealing part is in contact with the outer surface of the bottle mouth to a considerable extent, it is very effective against the inward fall of the mouth of the stretch blow molded bottle made of polyethylene terephthalate.
