Description

lid

The present invention relates to a cup lid.

Common beverage containers (such as plastic cups or paper cups) are usually fastened to the opening of the container by a plastic lid to prevent the liquid in the container from spilling and being easy to carry. In addition to the drinking port, the conventional plastic cup lid is also provided with a vent hole, when the container is used for accommodating hot drinks, the hot air can be discharged from the outside of the container, so as to avoid danger caused by excessive pressure inside the container.

Although the vent hole of the conventional plastic cup lid can allow hot air to be discharged from the container to reduce pressure, however, after the discharged hot air contacts the external cold air, it will condense into a liquid on the periphery of the vent hole and overflow, and the vent hole is open to the outside. It may also lead to the contamination or leakage of the beverage in the container, and there are disadvantages that need to be improved urgently.

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

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

In order to achieve the above object, the present invention provides a cup cover, comprising: a main body with a through hole; and a cover body, covered with the through hole, including a ventilation hole for communicating with the external space and a hole between the ventilation hole and the hole. A shielding portion between the through holes, the shielding portion encloses at least one through hole that communicates between the ventilation hole and the through hole, at least one of the through holes is open to an axial direction of the cover body and is connected to the ventilation hole at least partially out of phase.

The following examples only illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, and are described together first.

Please refer to FIGS. 1 to 3 , which show a preferred embodiment of the present invention. The cup cover 1 of the present invention includes a main body 10 and a cover body 20 .

The body 10 is provided with a through hole 11 ; the cover 20 covers the through hole 11 and includes a ventilation hole 21 for communicating with the external space and a shielding portion 22 between the ventilation hole 21 and the through hole 11 , The shielding portion 22 encloses at least one through hole 221 that communicates between the ventilation hole 21 and the through hole 11 , and at least one of the through holes 221 is open to an axial direction of the cover 20 and is at least partially connected to the ventilation hole 21 . Phase dislocation. Thereby, when the cup cover 1 is covered on a container 2 containing beverages, the through hole 11 , the at least one through hole 221 and the ventilation hole 21 are connected to allow the gas in the container 2 to be discharged, and the body 10 There is no need to provide additional ventilation holes, and the shielding portion 22 can allow hot air to condense between the cover 20 and the through hole 11 and prevent the beverage in the container 2 from being contaminated or leaking.

The cover body 20 includes a cover portion 23 with the ventilation hole 21 and a body portion 24 connected to the cover portion 23 . The body portion 24 encloses an inner space 241 , and the shielding portion 22 protrudes toward the inner space 241 . The exit is provided on the body 24 . In other embodiments, the body can also be solid and directly pass through a connecting channel that communicates between the ventilation hole and the through hole. . The shielding portion 22 includes at least one baffle plate 222 extending radially inward from an inner peripheral surface of the body portion 24 , and each baffle plate 222 defines at least one through hole 221 . In this embodiment, the shielding portion 22 includes a plurality of the baffles 222 circumferentially connected to the inner peripheral surface of the body 24 , the through holes 221 of each baffle 222 and the through hole 221 of the other baffle 222 . Axial dislocation; viewed along the axial direction, at least one of the baffles 222 shields at least 1/2 of the radial dimension of the through hole 11, as shown in FIG. 3, whereby each of the through holes 221 allows gas to flow freely, Each of the baffles 222 can effectively prevent the liquid in the container 2 from leaking and being polluted. Preferably, in the axial direction, the through hole 221 adjacent to the ventilation hole 21 does not overlap with the ventilation hole 21, and the leakage prevention effect is good. In other embodiments, each of the baffles can also extend obliquely toward the direction of the through hole, so as to facilitate the return of the liquid to the container.

In detail, the radial dimension of the cover portion 23 is larger than the radial dimension of the through hole 11 , and the sealing performance is good; the cover body 20 is a single component formed integrally, and has good structural strength. An inner wall surface of the through hole 11 and an outer wall surface of the cover body 20 are preferably respectively provided with a first engaging portion 111 and a second engaging portion detachably engaged with the first engaging portion 111 25; Referring to FIG. 3, in this embodiment, the first engaging portion 111 is an internal thread segment, and the second engaging portion 25 is an external thread segment, which can be stably engaged and not easily disengaged; the body 10 Preferably, a groove 12 is further provided, and the cover 20 can be inserted into the groove 12. The inner peripheral wall of the groove 12 can also be provided with the internal thread segment or other corresponding to the second engaging portion 25. The clamping structure can be used for clamping the cover 20 when drinking the beverage in the container 2 , which is convenient for use. Of course, the first and second engaging portions can also be configured with other structures according to requirements, such as buckle protrusions and buckle depressions.

Please refer to FIG. 4 , which shows another preferred embodiment of the present invention. The plurality of baffles 222a extend radially inward from the inner peripheral surface of the body 24a staggeredly so that the through holes 221a are axially displaced from each other. Similarly It can block liquid and allow the circulation of gas. The body 24a is provided with an annular protrusion 242 on the outer peripheral surface or a plurality of locking protrusions at intervals so as to stably contact the inner peripheral surface of the groove 12, and the structure is simple and easy to process.
