Description

Cup lid

The invention relates to a cup lid.

Generally, beverage containers (such as plastic cups or paper cups) are usually attached to the opening of the container by a plastic cup lid, so as to prevent the liquid in the container from spilling and making it easier to carry. The conventional plastic cup lid is not only provided with a drinking port, but also provided with a vent hole. When the container is used for holding hot drinks, hot air can be discharged from the outside of the container to avoid danger caused by excessive pressure inside the container.

Although the vent hole of the conventional plastic cup lid can be used for the hot air to exhaust the container to reduce pressure, however, the exhausted hot air will condense into liquid around the vent hole and overflow when it contacts the outside cold air, and the vent hole is open to the outside It may also lead to contamination or leakage of the beverage in the container, and there are shortcomings that need to be improved urgently.

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

The main purpose of the present invention is to provide a cup lid that is breathable and effectively prevents pollution and leakage.

In order to achieve the above object, the present invention provides a cup lid, which includes: a body with a through hole; and a lid body, which is arranged in the through hole, and includes an air hole for communicating with the external space and an air hole located between the air hole and the air hole. The shielding portion between the through holes, the shielding portion surrounds at least one through hole communicating between the vent hole and the through hole, and at least one through hole is open toward an axial direction of the cover and is connected to the vent hole At least part of the phase is misaligned.

The following examples are only used to illustrate the possible implementation aspects of the present invention, but they are not intended to limit the scope of protection of the present invention.

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

The main body 10 is provided with a through hole 11; the cover body 20 is disposed on the through hole 11 and includes an air hole 21 for communicating with the external space and a shielding portion 22 located between the air hole 21 and the through hole 11, The shielding portion 22 encloses at least one through hole 221 connected between the vent 21 and the through hole 11, and at least one through hole 221 is open toward an axial direction of the cover 20 and is at least partially connected to the vent 21 Phase misalignment. Thereby, when the lid 1 is placed on a container 2 containing a drink, the through hole 11, the at least one through hole 221, and the vent 21 are connected to allow the gas in the container 2 to escape, and the body 10 There is no need to provide an additional vent hole, and the shielding portion 22 can condense hot air between the lid 20 and the through hole 11 and prevent the beverage in the container 2 from being contaminated or leaked.

The cover body 20 includes a cover portion 23 provided with the vent 21 and a body portion 24 connected to the cover portion 23. The body portion 24 encloses an internal space 241, and the shielding portion 22 protrudes toward the internal space 241 The place of departure is set at the body 24. In other embodiments, the body can also be solid and directly penetrate a connecting channel between the vent hole and the through hole. The connecting channel can be, for example, a turning extension, an arc extension, or an oblique extension, etc. . The shielding portion 22 includes at least one baffle 222 extending radially inward from an inner peripheral surface of the body 24, and each baffle 222 is provided with at least one through hole 221. As 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, a through hole 221 of each baffle 222 and a through hole 221 of another baffle 222 Axial misalignment; viewed along the axial direction, at least one baffle 222 shields at least 1/2 of the radial dimension of the through hole 11, as shown in FIG. 3, whereby each through hole 221 allows gas to flow freely, Each of the baffles 222 can effectively prevent liquid leakage and contamination in the container 2. Preferably, in the axial direction, the through hole 221 adjacent to the vent hole 21 and the vent hole 21 do not overlap, and the leakage prevention effect is good. In other embodiments, each of the baffles can also extend obliquely toward the direction of the through holes, so as to facilitate the flow of liquid back into 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 an integrally formed single member with 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 clamping portion 111 and a second clamping portion detachably clamping with the first clamping portion 111 25; with reference to Figure 3, in this embodiment, the first clamping portion 111 is an internal thread segment, the second clamping portion 25 is an external thread segment, which can be stably engaged and not easily disengaged; the body 10 Preferably, a groove 12 is additionally provided, and the cover body 20 can be inserted into the groove 12, and the inner peripheral wall of the groove 12 can also be provided with the internal thread section or other corresponding to the second clamping portion 25 The snap connection structure can be used to snap the lid 20 when drinking the beverage in the container 2, which is convenient to use. Of course, the first and second clamping portions can also be configured in other structures according to requirements, such as buckle protrusions and buckle recesses.

Please refer to FIG. 4, which shows another preferred embodiment of the present invention. The plurality of baffles 222a extend radially inwardly from the inner peripheral surface of the body 24a so that the through holes 221a are axially misaligned with each other. It can stop the liquid and allow the flow of gas. The outer peripheral surface of the body 24a is provided with a ring protrusion 242 or a plurality of clamping protrusions on the interval circumference, which can stably abut against the inner peripheral surface of the groove 12, and has a simple structure and easy processing.
