When liquid is in the buffer groove 590, the liquid can flow back into the cup through the shaft hole 560 along the conical hopper. Therefore, the air holes formed at the bottom of the limiting groove 230 in embodiment 1 may not be present in this embodiment.

Fig. 6a-b are schematic diagrams of the structure of the cover body provided according to embodiment 2 of the present invention. As shown, an annular plug 690 having a reduced diameter at its distal opening is provided around the shaft 610 to fit into the buffer recess 590. The diameter of the annular plug 690 is slightly larger than the diameter of the relief groove 590 so that the two are in interference fit to prevent leakage of liquid from the annular plug gap.

According to an embodiment of the present invention, the rotating shaft 610 is concentrically disposed with the annular plug 690, and the ventilation groove 612 is formed along the sidewall of the rotating shaft. The air-permeable groove 612 is a semicircular groove, penetrates through the top end and the tail end of the rotating shaft 610, and can keep the air pressure in the cup same as the outside through the air-permeable groove 612, so that the air pressure balance is kept. A protrusion ring 611 is provided at the end of the rotation shaft 610. When the rotating shaft 610 is assembled into the shaft hole 560, the protruding ring 611 is caught on the bottom edge of the shaft hole 560, so that the cover body 600 can rotate around the shaft hole 560 and is not easily detached.

According to an embodiment of the present invention, as shown in fig. 6b, the outside of the cover body 600 is provided with an air hole 680 having an opening diameter of 0.2-2 mm, which is communicated with the inside of the cover body 600 at the bottom of the annular plug 690. An overflow preventing step 681 is provided at the inner side of the cover body 600 to protrude inward to communicate with the airing holes 680. The anti-overflow table 681 is a cylinder, and the height of the anti-overflow table is smaller than that of the annular plug 690, so that liquid can be prevented from overflowing out of the cup cover through the air holes 680.

According to an embodiment of the present invention, the cover body 600 is prevented from rubbing the top surface of the cup cover body 500 during rotation, and the method described in embodiment 1 is adopted to increase a circular truncated cone at the outer side of the bottom of the annular plug 690, so as to increase the distance from the lower surface of the cover body 600 to the top surface of the cup cover body 500; in other embodiments, as shown in FIG. 6b, one or more steps 670 are added to the inside of the cover 600 that mate with one or more steps of the cup cover 500.

Fig. 7a is a schematic cross-sectional view of a cup lid body provided according to embodiment 2 of the present invention. Fig. 7b is a schematic partial enlarged view of the cup lid body according to embodiment 2 of the present invention. As shown in the drawing, when the annular plug 690 is fitted into the buffer groove 590, a buffer space 691 is formed. The buffer space 691 is a closed space, the top of the buffer space is provided with a vent hole 680 communicated with the outside, and the bottom of the buffer space is provided with a vent groove 612 communicated with the space in the cup, so that a venting system of the cup is formed.

According to an embodiment of the present invention, when the air pressure in the cup is higher than the outside, the air in the cup flows into the buffer space 691 through the ventilation groove 612, and further flows into the outside through the ventilation hole 680; when a user drinks with the cup cover, the air pressure in the cup is smaller than that in the outside, air in the outside enters the buffer space through the air holes and enters the cup through the air holes 612, and the air pressure in the cup is balanced.

According to the utility model discloses an embodiment, when the cup takes place to rock or slope, gas and a small amount of liquid in the cup get into buffer space through the bleeder vent, because buffer space's cushioning effect for liquid is difficult to flow the cup outside, and gas runs outside the cup through bleeder vent 680, makes the inside and outside atmospheric pressure of cup reach the balance. At this time, the liquid in the buffer space flows back into the cup through the ventilation groove 612 due to gravity, so that the function of preventing spilling is realized.

Fig. 8 is a schematic view of an assembly of the cup lid body and the lid body according to embodiment 2 of the present invention. As shown in the figure, the cover body 600 is assembled on the cup cover body 500, the sealing plug 620 covers the drinking hole 510, and the two are in interference fit, so that the cup cover sealing function is realized. When the user wants to drink, pull up outward turn-ups 641 with the hand for lid 600 upwards buckles along indent 650, and the certain angle of rotation around the axis of rotation 610 for sealing stopper 620 aims at spacing groove 530 and pushes down, makes sealing stopper 620 fill in spacing groove 530, and the restriction lid swings at will, avoids influencing user experience.

The above embodiments are provided only for the purpose of illustration, and are not intended to limit the present invention, and those skilled in the relevant art can make various changes and modifications without departing from the scope of the present invention, and therefore, all equivalent technical solutions should also belong to the scope of the present invention.
