Abstract

The utility model relates to the technical field of coffee cups, in particular to a coffee cup cover with a rotary opening structure and an optimized heat preservation design, which comprises an upper cover and a lower cover, the upper cover is connected with the lower cover through threads, the upper cover comprises an outer rotary cover and an inner rotary cover which are mutually buckled and connected, and a foam pad for heat preservation is hidden in the inner rotary cover. Two waterproof silica gel parts are arranged on the inner screw cap in a sleeving manner; the lower cover comprises an inner plug cover and an inner plug outer ring which are connected in a buckled mode, and the inner plug cover is sleeved with a waterproof silica gel part. According to the coffee cup cover with the rotary opening structure and the optimized heat preservation design, by means of the innovative opening mode that the outer rotary cover is rotated by 180 degrees to enable the arc-shaped opening to be aligned with the drinking opening of the inner plug cover, the defects that a traditional rotary cover needs to be integrally screwed out, the safety problem is easily caused by cover bouncing operation, and the leakage prevention of a flip cover is poor are overcome. A user can quickly open the drinking opening only by simply rotating the outer screw cap, and the operation is simple, convenient and efficient when drinks are taken for multiple times.
