<p>PURPOSE: To downsize a molding tool of a mouth and also efficiently manufacture various bottles by providing an engaging part above a support ring formed at an opening of a plastic bottle wherein a separate mouth is engaged with a bottle body. CONSTITUTION: A plastic bottle widely used for holding various kinds of liquid such as feverages, soy sauce and salad oil is manufactured by engaging a separate mouth 2 with a bottle body 1, while an engaging part 4 is provided above a support ring 3 formed at an opening of the bottle body 1. By thus engaging the separate mouth 2 with the bottle body 1, mouths 2 having various shapes can be manufactured with small molding tools. In addition, since the engaging part 4 is provided above the support ring formed at the opening of the bottle body 1, the engaging part 4 can be protected by the support ring 3, thereby obtaining an entirely rigid bottle.</p> |
