Description

cup lid

The invention relates to a cup cover.

The container of general drink (such as plastic cup or paper cup) is usually fastened to the opening of this container by a plastic cup lid, prevents the liquid in this container from spilling and is easy to carry. In addition to being provided with a drinking port, the known plastic cup lid is also provided with a ventilating flow channel. When the container is used to accommodate hot drinks, hot air can be discharged from the container to avoid danger caused by excessive pressure inside the container.

Although the ventilation channel of the conventional plastic cup cover can discharge the hot air from the container to reduce the pressure, the discharged hot air will condense into liquid and overflow on the outer periphery of the ventilation channel after contacting the cold air outside. Opening to the outside may also result in contamination or leakage of the drink in the container. In order to solve the above-mentioned problems, a method has been developed on the market that covers the mouth of the plastic cup cover and penetrates a small air-permeable flow channel on the cover to achieve exhaust and anti-leakage. Effect. However, the air-ventilating channel on the cover still has the problem of leakage during travel, and the cover cannot be stably assembled to the plastic cup cover and is easy to fall off, so there are shortcomings that need to be improved urgently.

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

The main purpose of the present invention is to provide a cup cover which can prevent pollution and leakage and is easy to produce.
