BOTTLE CAP WITH LOW END GASKET

摘要

PURPOSE: A container lid is provided to prevent deformation by improving sealing properties. CONSTITUTION: A storage member (520) includes a discharge port at a lower side surface of an inner cap providing a path from a main cap (524) to the inlet of a container. An opening member (530) includes a slider (536) of an additive container function and is combined with an extension pipe (527) extended to an upper part of the main cap. A lower surface gasket (550) combines with a storage member by using a hook (553) and is separated from a slider. A lower and inner lid (560) is combined with a lower end of an outlet and simultaneously seals a lower surface and an inner surface. An inner vertical supporting unit supports a lower gasket and inner surface. A horizontal supporting unit (562) supports an inner vertical supporting unit in parallel. An inner surface supporting unit (561) supports a sealing ring (551) of the lower surface gasket at an external end of the horizontal supporting unit. A sealing ring supporting protrusion (563) is formed inside a side supporting unit.
