Description

Cup lid

The present invention relates to a cup cover, and more particularly to a cup cover suitable for covering over a cup.

Existing disposable cups or cups, such as cups, usually use a sealing film or a lid to seal the opening to avoid spillage of the beverage in the cup. Most of the cup lids currently on the market are made of plastic or paper, and the present invention provides an innovative cup cover for consumers to choose.

Accordingly, it is an object of the present invention to provide a cup cover that overcomes at least one of the disadvantages of the prior art.

Thus, the novel cup cover comprises a cover body integrally formed and defining a cover space, the cover body comprising a metal layer and two cover layers respectively coated on the inner and outer sides of the metal layer.

Referring to Figures 1, 2, and 3, an embodiment of the novel cup cover is adapted to be detachably covered over a cup 1 having a cup formed on the top side and surrounding a cup opening 11 defining Edge 12. The cover includes an integrally formed cover body 2. Of course, the cover may further include a printed body (not shown) formed on the outer side of the cover body 2, but this is not the focus of the present invention, so it is not here. Again.

Firstly, the cover body 2 includes a top cover wall 21, and a surrounding wall 22 surrounding the top cover wall 21 and surrounding the cover wall 21, the top cover wall 21 is matched with the surrounding wall 22. A cover space 23 with an opening facing downward is defined.

The top cover wall 21 is adapted to be correspondingly fitted over the cup opening 11 of the cup 1. The top cover wall 21 has a middle top portion 211, an inner side portion 212 projecting upward from a periphery of the middle top portion 211, and a cover portion A ring top 213 projecting laterally outwardly from a top edge of the inner portion 212 and a lower portion 214 extending downwardly from an outer periphery of the ring top 213 to connect the surrounding wall 22. The ring top 213 has a drinking hole 215 that communicates with the cover space 23. The middle top portion 211 is horizontally rounded, but in other embodiments, the shape may be changed, for example, having a recessed area, so the design is not limited to this embodiment.

The surrounding wall 22 is adapted to be fastened to the periphery of the cup edge 12 of the cup 1, the surrounding wall 22 having a laterally outwardly projecting edge of the outer side portion 214 of the top cover wall 21 and resting against the cup edge 12. An upper ring shoulder portion 221, a peripheral portion 222 extending downward from the outer peripheral edge of the ring shoulder portion 221 and abutting on the circumferential side of the cup edge 12, and an inward and downward direction from the bottom edge of the outer peripheral portion 222 The buckle portion 223 is bent and extended to the lower side of the cup edge 12.

In terms of structure, the cover body 2 further includes a metal layer 24 and two covering layers 25 respectively coated on the inner and outer sides of the metal layer 24, and the top cover wall 21 and the surrounding wall 22 The sheet 3 (see FIG. 4) of the three-layer structure in which the metal layer 24 is sandwiched between the cladding layers 25 is formed. In the embodiment, the material of the metal layer 24 is aluminum alloy (Al alloy). The material of each of the coating layers 25 is polyethylene terephthalate (PET), of course, the above materials are not limited thereto.

Referring to Figure 4, in order to more clearly illustrate the construction of the novel cup cover, the following is a further description of the manufacturing process in which the coating layers 25 are applied to both sides of the metal layer 24 during manufacture, or in the metal layer 24. The two side surfaces are formed into the coating layer 25, thereby forming a sheet or a roll of the sheet 3 having a three-layer structure. Then, the sheet 3 is sent to a cup forming machine (not shown), and a circular original piece 31 is punched out first, and then the circular original piece 31 is punched into the shape of the cover body 2, and then reshaped. The drinking hole 215 (see FIG. 1) is not described in detail because the manufacturing process is not the focus of the present invention.

In summary, the novel cup cover forms a three-layer structure of the coating layer 25 on the inner and outer surfaces of the metal layer 24, which is an unprecedented innovative design and provides consumers with a choice of opportunities. Achieve the purpose of this new type. Further, the material of the three-layer structure is such that the material of the coating layer 25 is an acid-base resistant polyethylene terephthalate, which prevents the aluminum alloy of the metal layer 24 from being metallic or dissolving harmful substances. It can solve the doubts that aluminum alloys release harmful substances in an acidic environment, which can improve the safety of use, effectively improve the market competitiveness and universal rate, and truly realize the advantages of environmental protection of the cup cover.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
