Abstract

The invention discloses a hot drink cup cover with a backflow cavity. The hot drink cup cover comprises a main cover body; the top wall of the main cover body is provided with a recessed part; the topopening of the recessed part is closed by a cover plate, and the cover plate is provided with a vent hole; the upper surface of the bottom wall of the recessed part is arranged towards the center ofthe top wall of the main cover body; the short axis of the elliptical bottom wall of the recessed part is horizontal, the long axis of the elliptical bottom wall of the recessed part is oblique, and the long axis and the center of the top wall of the main cover body are located on the same vertical plane; the bottom wall of the recessed part is provided with a backflow hole which is located in thebottom end of the long axis of the bottom wall of the recessed part. As the hot drink cup cover is provided with the backflow hole and the vent hole, gas in a cup can escape naturally; as the hot drink cup cover is further provided with the backflow cavity, liquid overflowing through the backflow hole can be temporarily stored and prevented from overflowing from the vent hole directly; as the structures and positions of the backflow cavity and the backflow hole are specially optimized, the situation that liquid overflows from the backflow hole can be reduced, and the backflow of liquid in thebackflow cavity is more facilitated.

Description

technical field [0001] The invention relates to a lid for a hot drink cup provided with a recirculation cavity. Background technique [0002] With the rise of the mobile Internet, more and more people choose to buy hot drinks on online food delivery platforms. [0003] At present, hot drink cups with lids are generally used for delivery of hot drinks. Due to the high temperature of hot drinks, the gas in the cup will expand during the delivery process, resulting in bursting and splashing of the cup lid, which brings bad experience to users. There are also health hazards. Therefore, the lid of the hot drink cup needs to be provided with vent holes to allow the gas expanded in the cup to leak out naturally and prevent the lid from being separated from the cup body. [0004] However, during the delivery process, the hot drink cup will inevitably shake. After the hot drink cup cover is equipped with vent holes, the hot drink in the cup may overflow the vent hole when shaking, ...
