SEALED LID SET AND PACKAGING CONTAINER USING THIS LID SET

Abstract

The application relates to a leak-proof lid assembly and a packaging container using this lid assembly. The lid assembly comprises an inner stopper (10), an inner lid (20), and a sealing element (25). The stopper has a dispensing area (13) with a dispensing hole (14). The lid has a dispensing groove and a sealing area (23). The sealing element is hermetically sealed to the inner lid. The lid is rotatably connected to the inner stopper by a rotating mechanism. The lid is made from a first plastic, the sealing element from a second plastic, and the lid and sealing element form a single unit manufactured by two-color injection molding. The hardness of the first plastic is greater than that of the second plastic.In the application, the sealing element and the inner cover are hermetically sealed, ensuring a good sealing effect.
