Description

Technical Field

[0001] This invention relates to the field of cup lid technology, and more particularly to a splash-proof cup lid. Background Technology

[0002] Beverages that can be made on-site, such as milk tea and coffee, are gradually gaining popularity. In order to cater to high-end consumers, they are packaged in disposable cups with lids.

[0003] These cup lids are basically divided into two types: one is the straight-insert type, where the straw is inserted and passes through the lid, and the other is the direct-drink type, where you can drink directly by opening the lid seal. The direct-drink type is designed to make the liquid flow more smoothly when drinking, but this type is prone to causing the beverage to spill out of the lid during delivery by the delivery person due to shaking, which greatly affects the eating experience. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a splash-proof cup lid that combines the direct insertion and direct drinking styles, and fundamentally solves the problem of beverages splashing out of the cup lid due to shaking.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A splash-proof cup lid includes: an outer lid and an inner lid that is adjustable and can prevent splashing inside the outer lid; the outer lid includes a limiter, a lid body for mounting the limiter, a drinking vessel mounted on the lid body, and a sealing cover for preventing water leakage from the drinking vessel; the inner lid includes a cover plate, a water-absorbing ring mounted on the cover plate, a lifter located at the center of the water-absorbing ring, a water outlet located on one side of the lifter, and a baffle plate located below the water outlet.

[0007] Preferably, the limiter includes a limit plate; one end of the limit plate has a rotating hole, and the other end has a limit hook.

[0008] Preferably, the cover includes a cover ring, a cover top mounted on the cover ring, a lifting hole in the cover top, and a rotating shaft disposed on one side of the lifting hole; the limiter is inserted into the rotating shaft through the rotating hole and connected to the cover; the inner cover is inserted into the lifting hole through a lifter and connected to the cover.

[0009] Preferably, the drinker includes a drinking ring mounted on the top of the lid, a drinking opening disposed on the drinking ring, and a pin disposed inside the drinking opening.

[0010] Preferably, the sealing cover includes a flange, a flap mounted on the flange, and a sealing cap disposed on the flap; the sealing cover seals the drinking vessel by fitting the sealing cap over the drinking spout.

[0011] Preferably, the lifting device consists of a cylinder and several rings fitted onto the cylinder, with a limiting opening between two adjacent rings; the limiting device is engaged with the limiting opening by a limiting hook to limit the lifting device.

[0012] Compared with the prior art, this application has the following beneficial effects:

[0013] This invention employs a combination of an outer and an inner lid. When a beverage is poured into the cup and the lid is closed, the inner lid, with its lifting function, is lowered onto the beverage surface. Then, a limiter on the outer lid restricts the inner lid in place. Thus, during delivery, the inner lid remains pressed against the beverage surface, significantly reducing the space for the beverage to move around in the cup and decreasing its kinetic energy. This prevents the beverage from splashing out through the gaps in the inner lid due to kinetic energy. Attached Figure Description

[0026] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0027] Example 1:

[0028] like Figures 1 to 8 As shown, a splash-proof cup lid includes: an outer lid 10, and an inner lid 20 disposed inside the outer lid 10 that is adjustable for splash prevention (e.g., ...). Figure 1 The outer cover 10 includes a limiter 11, a cover body 12 for mounting the limiter 11, a drinking vessel 13 mounted on the cover body 12, and a sealing cover 14 for preventing leakage from the drinking vessel 13 (e.g., Figure 2The inner cover 20 includes a cover plate 21, a water-absorbing ring 22 mounted on the cover plate 21, a lifter 23 located at the center of the water-absorbing ring 22, a water outlet 24 located on one side of the lifter 23, and a baffle plate 25 located below the water outlet 24 (e.g., Figure 6 , Figure 7 ).

[0029] The reason why beverages can spill out from the gap between the lid and the cup during delivery is that there is still a certain distance between the surface of the beverage in the cup and the lid. During delivery, this distance can cause the beverage to tumble in the space between the lid and the cup, generating kinetic energy. When the beverage splashes into the gap between the lid and the cup under this kinetic energy, it can easily seep out.

[0030] Therefore, to fundamentally solve the problem of beverage spillage, it is necessary to address the kinetic potential energy generated when the beverage is shaken. Thus, the anti-splashing cup lid of this invention adds an inner lid 20 to the existing outer lid 10. The inner lid 20 has a lifting function; when the cup is full of beverage, the outer lid 10 is closed, and the inner lid 20, located inside the outer lid 10, is lowered until it is flush with the beverage surface. In this way, the distance between the beverage surface and the inner lid 20 is zero. During delivery, the beverage can hardly shake, thus preventing the generation of kinetic potential energy and preventing spillage from the cup.

[0031] Furthermore, in order to realize the lifting function of the inner cover 20, a lifting device 23 is installed on the cover plate 21 of the inner cover 20. The lifting device 23 can be a manual device, and this embodiment does not limit it.

[0032] When the lifter 23 descends, it moves the cover plate 21 downwards and stops when it is in contact with the beverage surface. Then, the lifter 23 is limited by the limiter 11 on the outer cover 10, so that the cover plate 21 is always in contact with the beverage surface during the delivery process, preventing the beverage from generating potential energy due to shaking during delivery.

[0033] To prevent beverages from leaking out of the cup and lid 21 during delivery, a water-absorbing ring 22 is provided on the lid 21. The water-absorbing ring 22 has a water-absorbing and expanding function. The water that leaks out from the cup and lid 21 is absorbed by the water-absorbing ring 22, causing the water-absorbing ring 22 to expand, increasing the contact area between the water-absorbing ring 22 and the cup. Under the action of squeezing pressure, it further prevents beverages from leaking out of the cup and lid 21.

[0034] The baffle plate 25 is disposed below the outlet 24. Specifically, the baffle plate 25 is installed below the cover plate 21 (e.g., Figure 7 This design prevents beverages from spilling out of the water outlet 24 during delivery.

[0035] like Figure 3 As shown, the limiter 11 includes a limit plate 111; one end of the limit plate 111 is provided with a rotating hole 112, and the other end is provided with a limit hook 113.

[0036] like Figure 2 As shown, the cover 12 includes a cover ring 121, a cover top 122 mounted on the cover ring 121, a lifting hole 123 opened in the cover top 122, and a rotating shaft 124 disposed on one side of the lifting hole 123; the limiter 11 is inserted into the rotating shaft 124 through the rotating hole 112 and connected to the cover 12; the inner cover 20 is inserted into the lifting hole 123 and connected to the cover 12 through the lifter 23.

[0037] The limiter 11 can rotate on the rotating shaft 124 through the rotating hole 112. When the cup lid is placed on the cup, the limiter 111 rotates and moves away from the lifter 23, causing the lifter 23 to fall. When the lifter 23 stops falling, the cover plate 21 under the lifter 23 is attached to the beverage surface. At this time, the limiter 111 is rotated in the opposite direction to limit the lifter 23. During the delivery process, the cover plate 21 is always attached to the beverage surface to prevent the beverage from generating potential energy due to shaking.

[0038] like Figure 4 As shown, the drinking device 13 includes a drinking ring 131 mounted on the top of the cover 122, a drinking opening 132 disposed on the drinking ring 131, and a pin 133 disposed inside the drinking opening 132.

[0039] The water outlet 24 is inserted into the drinking port 132, and the pin 133 in the drinking port 132 is inserted into the water outlet 24.

[0040] A drinking ring 131 is installed on the lid 122 to facilitate drinking.

[0041] like Figure 5 As shown, the sealing cover 14 includes a flange 141, a flap 142 mounted on the flange 141, and a sealing cap 143 disposed on the flap 142; the sealing cover 14 is fitted onto the drinking spout 132 by the sealing cap 143 to seal the drinking vessel 13.

[0042] The flange 141 is mounted on the drinking ring 131.

[0043] Furthermore, in order to prevent the beverage liquid from leaking out from the gaps in the baffle plate 25 and flowing out through the outlet 24 from the drinking port 132, a sealing cap 14 is installed on the drinking ring 131. The sealing cap 143 on the sealing cap 14 is fitted onto the drinking port 132 to seal the drinking vessel 13. In this way, even if a little beverage liquid leaks out from the gaps in the baffle plate 25, it will not flow out from the drinking port 132.

[0044] like Figure 8 As shown, the lifting device 23 consists of a cylinder 231 and several rings 232 sleeved on the cylinder 231. A limiting port 233 is provided between two adjacent rings 232. The limiting device 11 is engaged in the limiting port 233 by a limiting hook 113 to limit the lifting device 23.

[0045] like Figures 1 to 8 As shown, the method of using the anti-splash and leak-proof cup lid is as follows: After the cup is filled with beverage, place the outer cover 10 on the paper cup, then flip the sealing cover 14 by the flange 141, and put the sealing cap 143 on the drinking spout 132. Then rotate the limiting plate 111 so that the limiting hook 113 on the limiting plate 111 disengages from the limiting port 233 on the lifting device 23, allowing the lifting device 23 to fall freely. When the cover plate 21 under the lifting device 23 is in contact with the beverage liquid surface, the lifting device 23 stops falling. At this time, rotate the limiting plate 111 in the opposite direction so that the limiting hook 113 on the limiting plate 111 hooks onto the limiting port 233 on the lifting device 23, limiting the lifting device 23. At this time, delivery can be carried out.

[0046] When the beverage reaches the user, simply open the limiting plate 111, pull the lifting device 23 to the highest point, and then limit the lifting device 23. At this time, the pin 133 in the drinking port 132 will push open the blocking plate 25 below the water outlet 24. Then open the sealing cover 14. When the user pours the paper cup, the beverage liquid can flow into the drinker's mouth through the water outlet 24 and the drinking port 132.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
