Description

lid

The present invention relates to a cup cover.

Generally, beverage containers (such as plastic cups or paper cups) are usually fastened to the opening of the container by a plastic lid to prevent the liquid in the container from spilling and being easy to carry. In addition to the drinking opening, the conventional plastic cup lid is also provided with a vent hole. When the container is used to hold hot drinks, the vent hole can be used to discharge hot air to the outside of the container, so as to avoid danger caused by excessive pressure inside the container. .

Although the vent hole of the conventional plastic cup cover can allow hot air to be discharged from the container to reduce pressure, the discharged hot air will condense into a liquid on the outer periphery of the vent flow channel after contacting the external cold air and overflow, and the vent hole is open to the outside. It may also lead to contamination or leakage of beverages in the container. In order to solve the aforementioned problems, a method has been developed in the market to cover the drinking opening of the plastic cup lid and pass a tiny ventilation hole through the lid to achieve the effects of exhaust and anti-leakage. . However, the vent holes on the cover still have the problem of leakage during running, and there are drawbacks that need to be improved urgently.

Therefore, it is necessary to provide a novel and progressive cup lid to solve the above problems.

The main purpose of the present invention is to provide a cup lid which can prevent contamination and leakage.

In order to achieve the above object, the present invention provides a cup cover, comprising: a main body, including a through hole extending along an axial direction and at least one groove part, the at least one groove part is at least partially open to the through hole and is connected to the main body one external.

The following examples only illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, and are described together first.
