Description

Technical Field

[0001] The present invention relates to the technical field of cup covers, and in particular to a splash-proof cup cover. Background Art

[0002] Beverages that can be made on site, such as milk tea and coffee, are gradually coming into people's view. In order to adapt to the high-end population, they are packaged in disposable cups with lids.

[0003] There are basically two types of cup lids. One is the direct-insert type, where you insert the straw through the cup lid; the other is the direct-drinking type, where you open the seal of the cup lid and drink from it. This direct-drinking type allows the liquid to flow more smoothly when drinking. However, during the delivery process, this method can easily cause the drink in the cup to spill out of the cup lid due to shaking, greatly affecting the eating experience. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a splash-proof cup cover which combines the direct insertion type and the direct drinking type and fundamentally solves the problem of beverage splashing out of the cup cover due to shaking.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A splash-proof cup cover comprises: an outer cover, and an inner cover which is arranged inside the outer cover and can be lifted and lowered to prevent splashing; the outer cover comprises a limiter, a cover body for mounting the limiter, a drinking vessel mounted on the cover body, and a sealing cover for preventing water leakage from the drinking vessel; the inner cover comprises a cover plate, a water absorption ring mounted on the cover plate, a lifter arranged at the center of the water absorption ring, a water outlet arranged on one side of the lifter, and a blocking sheet arranged below the water outlet.

[0007] Preferably, the limiter comprises a limit plate; a rotation hole is formed at one end of the limit plate, and a limit hook is formed at the other end.

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

[0009] Preferably, the drinking vessel comprises a drinking ring mounted on the top of the cover, a drinking port arranged on the drinking ring, and a thimble arranged in the drinking port.

[0010] Preferably, the sealing cover comprises a flange, a flap installed on the flange, and a sealing cap arranged on the flap; the sealing cover is sleeved on the drinking opening through the sealing cap to seal the drinking vessel.

[0011] Preferably, the lifter is composed of a cylinder, a plurality of rings sleeved on the cylinder, and a limiting opening is provided between two adjacent rings; the limiter limits the lifter by means of a limiting hook disposed in the limiting opening.

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

[0013] The present invention adopts a combination of an outer cover and an inner cover. When a drink is poured into the cup and the cup cover is put on, the inner cover has a lifting function, so that the inner cover is lowered onto the surface of the drink, and then the inner cover is limited by the limiter on the outer cover. In this way, during the delivery process, the inner cover is always pressed against the surface of the drink, which greatly reduces the space for the drink to shake in the cup and reduces the kinetic potential energy, thereby preventing the drink from splashing out from the gap of the inner cover with the help of the kinetic potential energy.

[0026] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0027] Embodiment 1:

[0028] like Figures 1 to 8 As shown, a splash-proof cup cover comprises: an outer cover 10, an inner cover 20 (such as Figure 1 ); the outer cover 10 includes a stopper 11, a cover body 12 for mounting the stopper 11, a drinking vessel 13 mounted on the cover body 12, and a sealing cover 14 (such as Figure 2); the inner cover 20 includes a cover plate 21, a water absorption ring 22 mounted on the cover plate 21, a lifter 23 disposed at the center of the water absorption ring 22, a water outlet 24 disposed on one side of the lifter 23, and a blocking sheet 25 disposed below the water outlet 24 (such as Figure 6 , Figure 7 ).

[0029] The fundamental reason why the beverage in the prior art splashes out from the contact gap between the cup lid and the cup during the dispensing process is that there is still a certain distance between the surface of the beverage in the cup and the cup lid, which is easy to cause shaking during the dispensing process. The shaking can cause the beverage in the cup to tumble in the space between the cup lid and the cup, forming dynamic potential energy. When the beverage splashes into the contact gap between the cup lid and the cup under the potential energy, it is easy to penetrate out.

[0030] Therefore, to solve the problem of beverage spillage, it is fundamentally necessary to solve the kinetic potential energy generated when the beverage is shaken. Therefore, the splash-proof cup cover described in the present invention has an inner cover 20 added on the basis of an outer cover 10. The inner cover 20 has a lifting function. When the cup is full of beverage, the outer cover 10 is covered, and the inner cover 20 arranged in the outer cover 10 is lowered to fit the surface of the beverage. In this way, the distance between the beverage surface and the inner cover 20 is zero. During the delivery process, the beverage can hardly be shaken, and kinetic potential energy cannot be generated, and it cannot spill out of the cup.

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

[0032] When the lifter 23 descends, it drives the cover plate 21 to move downward and stops when it is in contact with the surface of the beverage. 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 surface of the beverage during the delivery process, thereby preventing the beverage from generating potential energy due to shaking during delivery.

[0033] In order to prevent the beverage from seeping out from the joint between the cup and the cover plate 21 during the delivery process, a water absorption ring 22 is provided on the cover plate 21. The water absorption ring 22 has the function of absorbing water and expanding. The water seeping out from the joint between the cup and the cover plate 21 is absorbed by the water absorption ring 22, and the water absorption ring 22 expands, thereby increasing the joint area between the water absorption ring 22 and the cup. Under the action of the squeezing force, the beverage is further prevented from seeping out from the joint between the cup and the cover plate 21.

[0034] The blocking sheet 25 is arranged below the water outlet 24. Specifically, the blocking sheet 25 is installed below the cover plate 21 (such as Figure 7 ), such a design prevents the beverage from pouring out from the water outlet 24 during the delivery process.

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

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

[0037] The limiter 11 can rotate on the rotating shaft 124 through the rotating hole 112. When the cup cover is covered on the cup, the limit plate 111 is moved away from the lifter 23 by rotating, so that the lifter 23 falls. When the lifter 23 stops falling, the cover plate 21 under the lifter 23 is attached to the surface of the beverage. At this time, the limit plate 111 is rotated in the opposite direction and the lifter 23 is limited. During the delivery process, the cover plate 21 is always attached to the surface of the beverage to prevent the beverage from generating potential energy due to shaking.

[0038] like Figure 4 As shown, the drinking vessel 13 includes a drinking ring 131 installed on the cover top 122 , a drinking port 132 arranged on the drinking ring 131 , and a thimble 133 arranged in the drinking port 132 .

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

[0040] A drinking ring 131 is installed on the cover top 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 sleeved on the drinking opening 132 through 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 seeping out from the gap of the blocking sheet 25 and then flowing out from the drinking port 132 through the water outlet 24, a sealing cover 14 is installed on the drinking ring 131, and the sealing cap 143 on the sealing cover 14 is sleeved on the drinking port 132 to seal the drinking vessel 13. In this way, even if some beverage liquid seeps out from the gap of the blocking sheet 25, it will not flow out from the drinking port 132.

[0044] like Figure 8 As shown, the lifter 23 is composed of a cylinder 231, a plurality of rings 232 sleeved on the cylinder 231, and a limiting opening 233 is provided between two adjacent rings 232; the limiter 11 limits the lifter 23 by clamping the limiting hook 113 in the limiting opening 233.

[0045] like Figures 1 to 8 As shown, the method of using the splash-proof cup cover is as follows: when the cup is full of beverage, the outer cover 10 is placed on the paper cup, and then the sealing cover 14 is flipped over by the flange 141, and is sleeved on the drinking port 132 by the sealing cap 143, and then the limiting plate 111 is rotated to make the limiting hook 113 on the limiting plate 111 disengage from the limiting opening 233 on the lifter 23, so that the lifter 23 can fall freely, and when the cover plate 21 under the lifter 23 is attached to the liquid surface of the beverage, the lifter 23 stops falling, and at this time, the limiting plate 111 is rotated in the opposite direction to make the limiting hook 113 on the limiting plate 111 buckle the limiting opening 233 on the lifter 23 to limit the lifter 23, and then delivery can be carried out.

[0046] When the drink reaches the user, it is only necessary to open the limit plate 111, pull the lifter 23 to the highest point, and then limit the lifter 23. At this time, the ejector pin 133 in the drinking port 132 just pushes open the blocking sheet 25 below the water outlet 24, and then open the sealing cover 14. When the user pours the paper cup, the drink liquid can flow into the drinker's mouth through the drinking port 132 along the water outlet 24.

[0047] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.
