Description

Lid

The invention relates to a cup lid.

Generally, the beverage container is usually snapped with a plastic cup lid on the opening of the container or sealed with a plastic film to prevent the beverage in the container from spilling. However, the conventional plastic cup lid and the mouth of the cup have insufficient tightness, and the drink easily flows out of the interface during use, causing inconvenience to the user; a container sealed with a plastic film is torn or the plastic film is torn or After being punctured, it can no longer return to the closed state, and cannot effectively prevent the drink from leaking or foreign objects from entering the container. Therefore, a combined cup lid has been developed on the market, which includes a lid and a kit. The kit can be sleeved on the outer circumference of the container. The lid can be assembled with the kit to close the opening of the container. Can be opened and closed repeatedly. However, the conventional combined cup lid is poorly designed, and the opening of the container is easily misaligned with the lid member, resulting in poor sealing performance and further leakage of the contents.

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 which can be assembled stably and has good sealing performance.

In order to achieve the above object, the present invention provides a cup lid, including: a set body for sleeved on a cup body and abutting against a lip of the cup body; and a lid body detachably assembled to the sleeve body , Including a first peripheral wall, a second peripheral wall with a small diameter on the first peripheral wall, and a turning connecting portion connected between the first and second peripheral walls, the turning connecting portion including a facing to the sleeve body An annular surface and an abutting portion located above the outer side of the cup lip, and the annular surface and the abutting portion are for abutting against the cup lip.

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, and are described first.

Please refer to FIGS. 1 to 5, which show a preferred embodiment of the present invention. The cup cover 1 of the present invention includes a set body 10 and a cover body 20.

The sleeve body 10 is adapted to be sleeved on the cup body 30 and can abut against a lip 31 of the cup body 30; the cover body 20 is detachably assembled to the sleeve body 10 and includes a first peripheral wall 21 and a small A second peripheral wall 22 having a diameter in the first peripheral wall 21 and a turning connecting portion 23 connected between the first and second peripheral walls 21, 22, the turning connecting portion 23 includes an annular surface facing the sleeve body 10 231 and an abutting portion 232 located above the outer side of the cup lip 31, the annular surface 231 and the abutting portion 232 are for abutting against the cup lip 31. The turning connecting portion 23 may include a part of the first peripheral wall 21 adjacent to the ring surface 231. Thereby, the cup cover 1 and the cup body 30 can be assembled stably, and the sealing performance is good, and leakage is not easy.

The abutting portion 232 includes at least one abutting protrusion provided on the first peripheral wall 21, and the at least one abutting protrusion is configured to abut against the cup lip 31 in a radial direction. With reference to FIGS. 4 and 5, in this embodiment, the ring surface 231 axially faces the sleeve body 10, and the abutting portion 232 is integrally protruding between the first peripheral wall 21 and the ring surface 231 A ring step. The ring surface 231 and the ring step can respectively abut against the cup lip 31 in the axial and radial directions, and have good stability. In other embodiments, the ring surface can also face the sleeve obliquely; the at least one protrusion can also include a plurality of ribs arranged on the ring surface or the first peripheral wall at intervals, and the plurality of ribs can be The cup lip is provided to abut against the cup lip in the radial direction, which can also prevent the cup lip from being misaligned with the cover body. Preferably, a side of the abutting portion 232 away from the ring surface 231 is provided with an arc lead angle 233 for abutting the cup lip 31. When the cover body 20 is assembled with the sleeve body 10, the arc The lead angle 233 can be used to guide the cup lip 31 to avoid the cup lip 31 from being damaged by force.

In detail, an inner diameter of the surrounding structure of the abutting portion 232 is slightly equal to an outer diameter of the cup lip 31, whereby the abutting portion 232 can be radially limited and abut against the cup lip 31 to prevent leakage leak. With reference to FIG. 4, the maximum radial distance D1 between the abutting portion 232 and an inner surface of the second peripheral wall 22 is preferably not greater than the maximum between the inner peripheral surface of the cup body 30 and the outer peripheral edge of the cup lip 31 The radial distance D2 can ensure that the cup lip 31 axially abuts the ring surface 231 in an all-round way, and the sealing effect is good. In an axial direction A of the cup cover 1, the maximum distance D3 of the abutting portion 232 relative to the ring surface 231 is greater than 1/2 of the radial dimension of the cup lip 31, whereby the cup lip 31 and the abutment The portion 232 can stably abut in the radial direction. 5, when the cup lip 31 axially abuts the sleeve body 10 and the ring surface 231 and radially abuts against the abutment portion 232, the abutment portion 232 and the sleeve body 10 are between A gap G is maintained in the axial direction A, whereby the cup lip 31 can be squeezed and slightly deformed, and at the same time, it closely abuts the sleeve body 10, the ring surface 231 and the abutting portion 232, preventing seepage The leakage effect is good and the scope of application is wide.

The first peripheral wall 21 is provided with a first screw connection portion 211, the sleeve body 10 is provided with a second screw connection portion 11 that can be screwed with the first screw connection portion 211, and the first screw connection portion 211 is connected to the The abutting portions 232 are spaced apart to accommodate the cup lip 31. In this embodiment, the first screw connection portion 211 and the second screw connection portion 11 respectively include a plurality of convex sections 111, 212, and the distance between the abutment portion 232 and the first peripheral wall 21 is not less than At least one of the convex sections 111, 212 radially protrudes from the first peripheral wall 21 or the sleeve body 10 to ensure that the abutting portion 232 can radially abut the cup lip 31 with good stability. Of course, the first peripheral wall and the sleeve body can also be buckled by a buckling mechanism.

The outer peripheral surface of the sleeve body 10 includes a plurality of annular peripheral surfaces 12 arranged in steps. The radial dimension of the plurality of annular peripheral surfaces 12 gradually increases toward the cover body 20, and the thickness of the sleeve body 10 gradually increases toward the cover body 20. , The structure strength is good and it can abut the cup lip 31 stably. The sleeve body 10 further includes a plurality of buckle recesses 13 open to a side away from the cover body 20, and the plurality of buckle recesses 13 can be buckled with the buckle protrusions of a handle to be lifted, and the use convenience is good. Preferably, the cover body 20 further includes a through hole 24 and a closure member 25 detachably covering the through hole 24. The closure member 25 is integrally connected to the cover body 20 by a flexible strap 26, which is easy to Produced and easy to use.
