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.
A container mouth forming device for forming a mouth in a container that is formed primarily of paper or plastic, comprising a supporting section adapted to be attached to an outer surface of the container, an opening section supported on the supporting section for forming an opening in the container, an operating section for operating said opening section to form the opening in the container, said opening section and said operating section being positioned in opposing relation to each other with a U-shaped groove provided between said opening section and said operating section, said U-shaped groove having a thin wall portion, said operating section being connected to and supported by said supporting section through projecting support axles that are provided on both sides of said groove at positions spaced apart from said groove, said support axles having a cross-section that includes a laterally extending portion, and said opening section, said operating section and said supporting section being integrated through said thin wall portion and said support axles by molding.
A container mouth forming device for forming a mouth in a container that is formed primarily of paper or plastic, comprising a supporting section adapted to be attached to an outer surface of the container, an operating section connected to and supported on the supporting section, and an opening section connected to the operating section, said opening section possessing a lower surface and said supporting section possessing a lower surface, said opening section having a first end portion and an oppositely located second end portion, said operating section having a first end portion and an oppositely located second end portion, the operating section being positioned relative to the opening section so that the first end portion of the opening section is located adjacent to the first end portion of the operating section with a U-shaped gap being located between the first end portion of the opening section and the first end portion of the operating section, and a thin wall portion at a bottom of the U-shaped gap that interconnects the opening section and the operating section, the operating section being rotatable about an axis with rotation of the operating section in an upward direction closing said gap and causing the first end portion of the operating section to engage the first end portion of the opening section to move the opening section downwardly so that the lower surface of the opening section extends below the lower surface of the supporting section, the operating section being connected to the supporting section by a pair of support axles located on opposite sides of the U-shaped gap, the support axles each having a cross-shaped cross-section.
