Therefore, they cannot be understood as limiting the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] Example 1,

[0030] See Figures 1-6 The utility model discloses a cup cover structure, including a cup cover body 10. Specifically, the cup cover body 10 has a covering plate 11, a connecting edge 12 and a covering edge 13. The top of the connecting edge 12 is arranged around the periphery of the covering plate 11, and the covering edge 13 is arranged around the bottom end of the connecting edge 12. A snap-fit ​​groove 121 is provided on the connecting edge 12, and a protruding portion 14 protruding inward is provided at the connecting position between the covering edge 13 and the connecting edge 12. The protruding portion 14 is located below the snap-fit ​​groove 121.

[0031] On the basis of the above structure, when using the cup cover structure of the present invention, the cup cover structure can be used on the cup body 20 with the snap-fit ​​flange 21. When sealing the cup mouth of the cup body 20, the cup cover body 10 is sealed at the cup mouth, and the snap-fit ​​flange 21 of the cup body 20 can be correspondingly snap-fitted into the snap-fit ​​groove 121 of the connecting edge 12 of the cup cover body 10. At this time, the sealing edge 13 can extend downward to cover the outer periphery of the cup body 20, and the sealing plate 11 seals at the top of the cup mouth. In this way, the connection and sealing of the cup cover body 10 and the cup body 20 are achieved. At the same time, after the snap-fit ​​flange 21 of the cup body 20 is snapped into the snap-fit ​​groove 121 of the cup cover body 10, the protrusion 14 below the snap-fit ​​groove 121 is abutted against the bottom end of the snap-fit ​​flange 21. In this way, the protrusion 14 can prevent the snap-fit ​​flange 21 from being separated from the snap-fit ​​groove 121, and the sealing structure of the cup cover body 10 is more secure and not easy to fall off.

[0032] The sealing edge 13 is wrapped around the outer periphery of the cup mouth. After the clamping flange 21 of the cup mouth is clamped into the clamping groove 121 of the cup cover body 10, the sealing edge 13 is further sealed below the connection position to achieve a better sealing effect.

[0033] Furthermore, the bottom wall of the above-mentioned engaging groove 121 is connected to the top of the protrusion 14 by a first arc surface. In this way, after the engaging flange 21 of the cup body 20 is engaged with the engaging groove 121, it is guided by the first arc surface to transition to the engaging groove 121, facilitating smooth engagement. When the cup cover body 10 is separated from the cup body 20, force is applied to the cup cover body 10, and the engaging flange 21 can slide out of the engaging groove 121 along the first arc surface, facilitating the separation of the cup cover body 10 from the cup mouth of the cup body 20.

[0034] More specifically, the bottom end of the protrusion 14 is connected to the top of the cover edge 13 with a second arc surface. When the snap-fit ​​flange 21 of the cup body 20 is snapped into the snap-fit ​​groove 121, the snap-fit ​​flange 21 can first be guided by the second arc surface to pass over the protrusion 14, and then be guided by the first arc surface to be snapped into the snap-fit ​​groove 121, so that the snap-fit ​​process is smoother.

[0035] When the cup cover body 10 is separated from the cup body 20, the engaging flange 21 can be guided by the first arc surface to slide out of the protruding portion 14, and then guided by the second arc surface to slide out, making the disassembly and assembly process smoother.

[0036] Furthermore, the sealing edge 13 gradually tilts outward from top to bottom, that is, the sealing edge 13 gradually tightens from bottom to top, so that after the snap-fit ​​flange 21 of the cup body 20 is snapped into the snap-fit ​​groove 121, the sealing edge 13 is tightened at the upper connection position, so that the snap-fit ​​sealing structure of the cup cover body 10 is more secure and not easy to detach.

[0037] See also Figure 1 as well as Figure 2In this embodiment, the top surface of the cover plate 11 is provided with a scoring portion 111. The scoring portion 111 is formed by a blade or other structure to provide a cutting mark on the top surface of the cover plate 11, and the scoring does not pass through the bottom surface of the cover plate 11. That is, in the initial state, the top surface of the cover plate 11 is provided with a scoring structure, while the bottom surface of the cover plate 11 is a blind end. In this way, when a straw needs to be inserted into the cup lid body 10 or the cup lid needs to be punctured to directly drink the beverage in the cup body 20, pressure can be applied to the scoring portion 111. The scoring portion 111 is relatively weak, so squeezing this position can make the top surface of the cover plate 11 penetrate to the bottom surface, allowing the straw to pass through or directly forming an opening structure at this position, so as to facilitate drinking of beverages when the cup lid body 10 is in the closed state.

[0038] Specifically, the scratch portion 111 is arranged in a cross shape, see Figure 1 That is, when subjected to force, force can be applied to the middle position of the scratch portion 111. The scratch structure formed by the "cross" is relatively weak in the middle and is easier to puncture.

[0039] Since the scoring portion 111 is a non-through structure, after the cup cover body 10 is closed, as long as the scoring portion 111 is not punctured, the beverage in the cup body will not spill out of the covering plate 11 , and there is no need to provide an additional plugging structure.

[0040] Of course, the scratch portion 111 can be set in other shapes such as an "I" shape or an "X" shape, and the specific shape is selected according to actual needs, so that the scratch portion 111 can be punctured when subjected to force.

[0041] See also Figure 3 、 Figure 4 as well as Figure 5 Alternatively, a direct drinking port 112 may be directly provided on the sealing plate 11 , and after the cup cover body 10 is sealed to the cup body 20 , the drink can be directly consumed through the direct drinking port 112 .

[0042] However, based on this structure, when there is no need to drink, a plug structure can also be provided at the drinking port 112 to prevent spillage.

[0043] Furthermore, the cup cover body 10 in this embodiment is made of pulp fiberboard or bamboo pulp fiberboard. The structure of the cup cover body 10 made of pulp fiberboard or bamboo pulp fiberboard is plant fiber, which is easier to degrade than plastic materials and is environmentally friendly.

[0044] Specifically, since the cup lid body 10 made of pulp fiberboard or bamboo pulp fiberboard is prone to poor strength, it can be integrally formed through the direct pressing process in the prior art (using molds, direct pressing machines, etc. in the prior art to apply pressure), so that the cup lid body 10 made in this way has better structural strength.

[0045] Furthermore, during the direct pressing process of pulp fiberboard or bamboo pulp fiber, wrinkles are easily formed at the edge due to the extrusion of the fiber structure, resulting in wrinkles and unevenness of the formed cover edge 13. Therefore, the cover edge 13 can be provided with a plurality of arc-shaped protrusions 131 and a plurality of arc-shaped grooves 132. The plurality of arc-shaped protrusions 131 are spaced apart in the circumferential direction of the cover edge 13, and adjacent arc-shaped protrusions 131 are connected by the arc-shaped grooves 132. In other words, the arc-shaped protrusions 131 formed by extrusion are disconnected by the arc-shaped grooves 132. In this way, a continuous structure is not formed, and wrinkles caused by the accumulation of the fiber structure during the extrusion process are prevented. The resulting cover edge 13 has a smoother structure.

[0046] Example 2,

[0047] See also Figure 1-Figure 7 The cup body shown includes a cup body 20 and the cup cover structure in Example 1, and a snap-in flange 21 is provided around the cup rim of the cup body 20; the snap-in flange 21 is used to snap into the snap-in groove 121, and the protrusion 14 is used to abut against the bottom end of the snap-in flange 21 after the snap-in flange 21 is snapped into the snap-in groove 121.

[0048] The cup cover structure can be used on a cup body 20 having a snap-fit ​​flange 21. When sealing the mouth of the cup body 20, the cup cover body 10 is sealed at the mouth of the cup. The snap-fit ​​flange 21 of the cup body 20 can be correspondingly snap-fitted into the snap-fit ​​groove 121 of the connecting edge 12 of the cup cover body 10. At this time, the sealing edge 13 can extend downward to cover the outer periphery of the cup body 20, and the sealing plate 11 seals at the top of the mouth of the cup. In this way, the connection and sealing of the cup cover body 10 and the cup body 20 are achieved. At the same time, after the snap-fit ​​flange 21 of the cup body 20 is snapped into the snap-fit ​​groove 121 of the cup cover body 10, the protrusion 14 below the snap-fit ​​groove 121 is abutted against the bottom end of the snap-fit ​​flange 21. In this way, the protrusion 14 can prevent the snap-fit ​​flange 21 from being separated from the snap-fit ​​groove 121, and the sealing structure of the cup cover body 10 is more secure and not easy to fall off.

[0049] The sealing edge 13 is wrapped around the outer periphery of the cup mouth. After the clamping flange 21 of the cup mouth is clamped into the clamping groove 121 of the cup cover body 10, the sealing edge 13 is further sealed below the connection position to achieve a better sealing effect.

[0050] It should be noted that the cup cover structure and working principle used for sealing the cup mouth of the cup body 20 are the same as those in Example 1, and the other structures of the above-mentioned cup body 20 are the same as the cup body 20 structure in the prior art, which will not be described in detail here.

[0051] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
