Wherein, the through hole 11 can be the drinking port of the cup cover 1; the at least one slot portion 12,12a may be, for example, a through slot, a blind slot, or other relatively concave similar structure. When the cap 1 is covered on a container 2 containing beverage and the through hole 11 is covered on a cover 20, the interior of the container 2 can be communicated with the outside through the at least one groove 12,12a to allow gas to circulate, and the body 10 does not need to be provided with ventilation holes in a penetrating way, and can be suitable for the existing cover.

The cap 1 further includes the cap 20, and at least one ventilation channel 30 is defined between the cap 20 and the at least one groove 12,12a to allow air to circulate. In this embodiment, the body 10 further includes a hole wall 13 surrounding the through hole 11, and the at least one groove 12,12a is concavely disposed inside the hole wall 13 and radially opened toward the through hole 11, so that the at least one groove 12,12a can be directly formed during manufacturing of the cup cover 1, which is convenient. In other embodiments, the at least one groove portion may be a through groove extending in a bending manner and circumferentially closed, and the through groove is opened to the through hole through one end for gas circulation.

Preferably, the body 10 includes a plurality of grooves 12,12a, the grooves 12,12a are spaced apart from each other in the circumferential direction of the hole wall 13 and extend along the axial direction, so that the ventilation effect is good and the fastening stability of the cover 20 and the hole wall 13 is maintained. Referring to fig. 3 to 5, the cover 20 includes a plurality of spaced baffles 21, at least one communication channel 22 is defined between two adjacent baffles 21, each ventilation channel 30 is communicated with one communication channel 22, so that hot air can be condensed in the at least one communication channel 22, and beverage in the container 2 is not easy to leak out. At least one of the baffles 21 is circumferentially abutted against the hole wall 13 and seals the through hole 11, and the peripheral wall of at least one of the baffles 21 faces the at least one groove 12,12a, and the extending length of the at least one groove 12,12a is longer than the thickness of the baffle 21 in the axial direction, so that the leakage of liquid in the container can be effectively prevented and the circulation of gas is allowed. In this embodiment, each of the baffles 21 circumferentially abuts the hole wall 13 and the outer peripheral wall faces one of the grooves 12,12a, so as to avoid oversized holes between the cover 20 and the hole wall 13.

Further, each of the baffles 21 circumferentially closes the through hole 11, and the plurality of grooves 12,12a are at least partially offset in the axial direction; the through hole 11 includes a first port 111 and a second port 112 axially opposite to each other, and one of the plurality of grooves 12,12a communicates with the first port 111 and the other communicates with the second port 112. When in use, gas can enter the connecting channel 22 from the groove part 12 through the ventilation channel 30 and then be discharged to the outside from the groove part 12a, and leakage of liquid is prevented through the bent path, so that the structure is simple and the use effect is good. In other embodiments, the body 10a may be provided with only one groove 12b, and the groove 12b extends along the axial direction and communicates with the first port 111 and the second port 112, as shown in fig. 6, so that the liquid can still enter the at least one connecting channel 22 to achieve the buffering effect; each groove part can also bend and extend on the hole wall to prevent liquid from directly passing through.

In detail, the baffles 21 include an upper surface 211 and a lower surface 212 facing the at least one connecting channel 22, and an extending height of the through hole 11 in the axial direction is not smaller than a distance between the upper surface 211 and the lower surface 212, so as to prevent beverage in the container 2 from directly entering the at least one connecting channel 22. The cover 20 further includes a connecting portion 23 connected to the plurality of baffles 21 at intervals, and the connecting portion 23 includes at least one column 231, which is simple in structure and easy to process and form. In this embodiment, the cover 20 is an integrally formed single member, and a radial dimension of each of the columns 231 is not smaller than a thickness of the baffle 21, so that the cover is strong in structure and not easy to break; the at least one column 231 extends parallel to the axial direction, so that the cover 20 can be easily detached by applying force, and is not easily damaged due to improper stress. Preferably, each baffle 21 is slightly deformable under force, so as to facilitate disassembly and the sealing of the hole wall 13 is better. In this embodiment, the cover 20 includes two baffles 21, and the two baffles 21 define a connecting channel 22 therebetween, and the connecting channel 22 extends annularly and is circumferentially open to the hole wall 13, so as to allow the liquid flowing into the cover 20 to be removed when the cover is pulled out of the body 10, thereby effectively avoiding blockage.

In other embodiments, the first engaging portion may be an annular flange; one of the first clamping part and the second clamping part can be provided with at least one clamping convex part, and the other one is provided with at least one clamping concave part which can be clamped with the at least one clamping convex part; the through hole can also be gradually reduced towards one side of the container in the axial direction, and the limit effect can be achieved by radially pressing the hole wall against the cover body.

The cover 20 further includes a top surface 25 and a head 26 connected to the top surface 25, and in the axial direction, the top surface 25 is not higher than the through hole 11, as shown in fig. 5, so that the cover 20 is not easy to fall off due to collision. The body 10 is further provided with a groove 15, the cover 20 can be inserted into the groove 15, the inner peripheral wall of the groove 13 can be clamped with the cover 20 in a tight fit manner or is provided with clamping structures such as a clamping protrusion, a clamping recess and the like, and when the beverage in the container 2 is drunk, the groove 13 can be used for clamping the cover 20, so that the use convenience is good, the sanitation is good, and the cover 20 can be prevented from being lost.

Referring to the third preferred embodiment shown in fig. 7, the first engaging portion 14a is a recess adjacent to the through hole 11, and the second engaging portion 24a is a protrusion integrally extending from the baffle 21a, and the protrusion can be fastened to the recess to position the cover 20a for convenient operation. The groove 12c extends transversely to the axial direction and is concavely formed on an end surface of the hole wall 13a adjacent to the first port 111, and the groove 12d is concavely formed on the inner side of the hole wall 13a and is communicated with the second port 112, so that the opening directions of the ventilation channels 30a,30b are different, and the anti-leakage effect is good. In other embodiments, the first engaging portion may be a convex engaging portion, and the second engaging portion may be a concave engaging portion, which may achieve the same effect.
