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, includes a lid portion, a body portion connected to the lid portion, and a lid body. A ventilation hole for communicating with an external space and a shielding portion, the body enclosing an internal space, the shielding portion is provided in the internal space and at least one through hole communicating between the ventilation hole and the through hole is constructed, at least A through hole is opened toward an axial direction of the cover body.

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 body 10 is provided with a through hole 11; the cover body 20 is disposed on the through hole 11 and includes a cover portion 23, a body portion 24 connected to the cover portion 23, a vent 21 for communicating with the external space, and a The shielding portion 22, the body portion 24 enclosing an internal space 241, the shielding portion 22 is provided in the internal space 241 and enclosing at least one through hole 221 connected between the vent 21 and the through hole 11, at least one The through hole 221 is open toward an axial direction of the cover 20. 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.

In the axial direction, the vent 21 is preferably higher than a top surface 13 of the main body 10, so that the beverage inside the container 2 will not easily touch the vent 21 due to shaking during the movement. The vent 21 is provided on the cover 23, and the shielding portion 22 is provided on the body 24 protruding toward the inner space 241. The shielding portion 22 includes at least one baffle 222 extending radially inward from the body 24, and each baffle 222 is provided with at least one through hole 221. In this embodiment, the shielding portion 22 includes a plurality of the baffles 222, and one of the baffles 222 covers a side of the inner space 241 opposite to the cover 23; in the axial direction, the at least one through hole 221 and The vent holes 21 are spaced and aligned so that hot air can condense in the internal space 241, and the beverage in the container 2 will not directly leak out of the vent holes 21, and the ventilation effect is good; viewed along the axial direction, at least A baffle 222 shields at least 1/2 of the radial dimension of the through hole 11, and the blocking effect is good.

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 20 can be inserted into the groove 12, and the inner peripheral wall of the groove 12 may also be provided with the internal thread section or other corresponding to the second clamping portion 25 The clamping structure allows the lid 20 to be clamped 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 the second preferred embodiment of the present invention. The shielding portion 22a includes a baffle 222a integrally extending radially inward from the body portion 24a and covering the inner space 241a. The radial dimension of the at least one through hole 221a is smaller than the radial dimension of the vent 21, which can be This effectively reduces the probability of the liquid inside the container penetrating into the internal space 241a, while keeping the gas flowable. The outer peripheral surface of the body 24a is provided with a ring protrusion 242 or a plurality of clamping protrusions on the spaced periphery, which can stably abut against the inner peripheral surface of the through hole 11 or the groove 12, and has a simple structure and easy processing.

Please refer to FIG. 5, which shows a third preferred embodiment of the present invention. In the axial direction, at least one of the through hole 221b and the vent hole 21 are at least partially misaligned; preferably, in the axial direction, the through hole 221b adjacent to the vent hole 21 does not overlap with the vent hole 21 to prevent Good leakage effect. In this embodiment, the shielding portion 22b includes a plurality of the baffles 222b circumferentially connected to the inner peripheral surface of the body 24b, a through hole 221b of each baffle 222b and a through hole 221b of the other baffle 222b Displacement in the axial direction, whereby each of the through holes 221b allows gas to circulate freely, and each of the baffles 222b can effectively prevent liquid leakage and contamination in the container. 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. .

Please refer to FIG. 6, which shows a fourth preferred embodiment of the present invention. The plurality of baffles 222c alternately extend radially inwardly from the inner peripheral surface of the body 24c, so that the through holes 221c are axially displaced from each other, which can also block liquid and allow the flow of gas.

Please refer to FIG. 7, which shows a fifth preferred embodiment of the present invention. Each baffle 222d can also extend obliquely to the direction of the through hole 221d relative to the axial direction, which facilitates the flow of liquid back into the container along each baffle 222d.
