Problems solved by technology
A single buckle product, but the structure is complex, and subsequent manual assembly is required: it is time-consuming to drill self-tapping screws and it is difficult to control its tightness. The above two solutions are not efficient. These problems have always plagued the assembly of the cup lid and inner plug.

The invention relates to a vacuum cup cover molded by using two different injection molding materials, which belongs to the technical fields of injection molding and design and manufacturing of cup covers. The vacuum cup cover has the characteristics that: both an outer cover and an inner plug are molded by injecting plastic, wherein the inner plug is molded by injecting heat-resistant, nontoxic and food-grade plastic; and the outer cover is molded by injecting high-strength plastic. The vacuum cup cover has the following structure that: the inner plug is an eccentric cylinder with a mouth upward, and the end part of the cylinder mouth is provided with a flanged edge which is vertical to the edge of the cylinder; the outer cover is an eccentric cylinder with a mouth downward, wherein the center of the eccentric cylinder is a cylindric concave with a mouth upward; the outer surface of the cylindric concave is fitted with the inner surface of the cylindric inner plug; and the fitted cylindric vertical wall is provided with an interlayer of which an inner wall and an outer wall are made of two different injection materials by permeating and intermixing with each other; the vacuum cup cover is provided with an interlayer which is permeated into and intermixed with the flanged edge; and the concave is filled with a same-shaped insulating material. The vacuum cup cover has the advantages that complicated manual assembling is avoided, the processing is simplified, and the labor productivity is greatly improved.
Description
technical field [0001] The invention belongs to the technical fields of injection molding technology and cup cover design and manufacture. [0002] Background technique [0003] Common cup lids and inner plugs are assembled with ultrasonic waves or self-tapping screws. A single buckle product, but the structure is complex, and subsequent manual assembly is required: tapping self-tapping screws is time-consuming and it is difficult to control its tightness. The above two solutions are not efficient. These problems have always plagued the assembly of the cup lid and inner plug. Contents of the invention [0004] The invention provides a vacuum cup cover molded by two different injection molding materials with convenient processing, high production efficiency and high reliability. [0005] The technical scheme adopted in the present invention: [0006] A vacuum cup lid is injection molded from two different materials, the vacuum cup lid is used to combine with the cup body...
