Abstract
A mouth forming device for a container includes an opening section, an operating section and a supporting section which are disposed in substantially the same plane. A substantially U-shaped groove is provided between one end portion of the opening section and one end portion of the operating section. The supporting section surrounds a portion of the opening section and the operating section. The operating section is linked to and supported by the supporting section through axles. The opening section, the operating section and the supporting section are integrated through a thin wall portion and the support axles by molding. When the other end portion of the operating section is raised, the axles are twisted and the operating section rotates about the axles to close groove. Accordingly, the end portion of the opening section is pressed by the end portion of the operating section and the part of the container located beneath the opening section is opened by the opening section.
