The main functions of a cup lid are to maintain the temperature of the beverage, prevent dust and foreign objects from falling into the cup, and facilitate carrying and drinking. Some specially designed cup lids also offer multiple functions such as leak prevention, straw insertion, and flow control, greatly enhancing the user experience.

[0003] Most cup lids on the market today typically have an upper lid and a lower lid. The upper and lower lids are often connected by threads to ensure structural stability. However, because of the threaded connection, the threaded holes or screws on the lid are exposed on the outer wall of the lid, which seriously affects the overall aesthetics of the lid.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] The existing cup lids often use threaded connections to connect the upper and lower lids to ensure structural stability. However, this threaded connection exposes the threaded holes or screws on the outer wall of the lid, severely affecting its overall aesthetics. The technical solution adopted by this invention to solve this problem is as follows:

[0006] A cup lid fixing structure includes a cup lid body, the cup lid body including an upper lid and a lower lid, and a connecting mechanism is provided between the upper lid and the lower lid. The connecting mechanism includes a first connecting part located on the side of the upper lid near the lower lid and a second connecting part located on the side of the lower lid near the upper lid. The first connecting part and the second connecting part cooperate to allow the upper lid and the lower lid to be detachably connected.

[0007] Furthermore, the first connecting part is a buckle located on the inner sidewall of the upper cover and extending toward the lower cover, and the second connecting part is a slot located on the inner sidewall of the lower cover and engaging with the buckle.

[0008] Furthermore, the buckles are spaced apart along the circumference of the upper cover, and the slots are spaced apart along the circumference of the lower cover.

[0009] Furthermore, the lower cover includes a first lower cover and a second lower cover sleeved on the outer side wall of the first lower cover. The slot is located on the first lower cover, and an installation mechanism is provided between the first lower cover and the second lower cover. The first lower cover is detachably connected to the second lower cover through the installation mechanism.

[0010] Furthermore, the mounting mechanism includes a mounting slot on the second lower cover and a mounting protrusion on the first lower cover, the mounting protrusion extending into the mounting slot so that the first lower cover restricts the axial mounting position of the second lower cover.

[0011] Furthermore, the buckle is integrally formed on the inner side wall of the upper cover.

[0012] Furthermore, a handle mechanism is provided on the side of the upper cover away from the lower cover. The handle mechanism includes a handle mounting base fixedly disposed on the upper cover, a handle housing detachably connected to the handle mounting base, and a handle cover located above the handle housing.

[0013] Furthermore, the handle mounting base is integrally formed on the surface of the upper cover, and a reinforcing rib is provided between the handle mounting base and the surface of the upper cover.

[0014] Furthermore, the handle mounting base extends toward the handle housing and into the handle housing, the handle mounting base is provided with a first connecting hole, and the handle housing is provided with a second connecting hole that is threadedly connected to the first connecting hole.

[0025] Figure 7 for Figure 4 An enlarged view of section C marked with a symbol. Detailed Implementation

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 7 The cup lid fixing structure shown includes a cup lid body 1, which includes an upper lid body 2 and a lower lid body 3. A connecting mechanism is provided between the upper lid body 2 and the lower lid body 3. The connecting mechanism includes a first connecting part located on the side of the upper lid body 2 near the lower lid body 3 and a second connecting part located on the side of the lower lid body 3 near the upper lid body 2. The first connecting part and the second connecting part cooperate to make the upper lid body 2 and the lower lid body 3 detachably connected.

[0028] This invention features a first connecting part on the side of the upper cover near the lower cover and a second connecting part on the side of the lower cover near the upper cover. When the upper and lower covers are connected by the first and second connecting parts, both the first and second connecting parts are hidden between the upper and lower covers, making the connecting mechanism invisible to the user from the outside. This improves the overall aesthetics of the cup lid and effectively solves the problem that existing cup lids often use threaded connections to connect the upper and lower lids to ensure structural stability. However, due to the threaded connection method, the threaded holes or screws on the cup lid are exposed on the outer wall of the cup lid, which seriously affects the overall aesthetics of the cup lid.

[0029] Optionally, in some embodiments, the first connecting part is a connecting protrusion located on the inner sidewall of the upper cover 2 and extending towards the lower cover 3, and the second connecting part is a connecting round hole located on the inner sidewall of the lower cover 3 and corresponding to the connecting protrusion. When the upper cover 2 and the lower cover 3 are closed, the connecting protrusion and the connecting round hole are inserted and engaged. At this time, the connecting protrusion and the connecting round hole are both hidden between the upper cover 2 and the lower cover 3, so that the user cannot see the connecting protrusion and the connecting round hole from the outside, which helps to improve the overall aesthetics of the cup lid body 1.

[0030] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the first connecting part is a buckle 41 located on the inner side wall of the upper cover 2 and extending towards the lower cover 3, and the second connecting part is a slot 42 located on the inner side wall of the lower cover 3 and corresponding to the buckle 41. When the upper cover 2 and the lower cover 3 are closed, the buckle 41 and the slot 42 engage. At this time, both the buckle 41 and the slot 42 are hidden between the upper cover 2 and the lower cover 3, so that the user cannot see the buckle 41 and the slot 42 from the outside, which helps to improve the overall aesthetics of the cup lid body 1.

[0031] Optionally, in some embodiments, both the upper cover 2 and the lower cover 3 are made of plastic, such as polypropylene or polyethylene. Plastic is relatively lightweight, so that the overall weight of the cup lid body 1 is relatively light, making it easy for users to carry and use. Secondly, plastic has good plasticity and can be made into various complex shapes and structures through molding processes such as injection molding and blow molding, which helps to meet the personalized needs of users.

[0032] Optionally, in some embodiments, both the upper cover 2 and the lower cover 3 are made of metal, such as stainless steel or titanium alloy. Metal is relatively strong and not easily deformed or damaged by external impact, which helps to extend the service life of the cup lid body. Secondly, metal has a unique texture and luster, which helps to improve the appearance quality of the cup lid body 1.

[0033] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the upper cover 2 is made of plastic and the lower cover 3 is made of metal. The plastic upper cover 2 can significantly reduce the overall weight of the cup lid body 1, making it more convenient for users to carry. The metal lower cover 3 can provide a sturdy structural support, which is beneficial to enhancing the durability and impact resistance of the cup lid body 1. Secondly, the metal lower cover 3 can utilize its good thermal conductivity to maintain the temperature of the beverage to a certain extent. At the same time, the plastic upper cover 2 plays a role in heat insulation, which helps to slow down the rate at which heat is lost from the top of the cup lid body 1, thereby achieving an optimized balance between heat preservation and heat insulation.

[0034] like Figures 1 to 7The first connecting part shown is a buckle 41 located on the inner side wall of the upper cover 2 and extending toward the lower cover 3, and the second connecting part is a groove 42 located on the inner side wall of the lower cover 3 and engaging with the buckle 41.

[0035] Furthermore, the snap-fit ​​between the buckle 41 and the slot 42 provides a relatively stable connection. When the cup lid body 1 is installed, the buckle 41 is firmly locked in the slot 42, which can effectively prevent the upper lid body 2 and the lower lid body 3 from accidentally separating during normal use.

[0036] Furthermore, the buckle 41 and the slot 42 are respectively provided on the inner side wall of the upper cover 2 and the inner side wall of the lower cover 3. From the outside, the buckle 41 and the slot 42 are hidden, so that the overall appearance of the cup lid body 1 is more concise and beautiful.

[0037] Furthermore, the snap-fit ​​connection between the buckle 41 and the slot 42 provides a convenient installation method. Users do not need to use additional tools. Compared with the traditional threaded connection, users only need to align the buckle 41 and the slot 42 and press gently to complete the installation, which helps to improve the assembly efficiency of the cup lid body 1.

[0038] like Figures 1 to 7 The buckles 41 shown are spaced apart along the circumference of the upper cover 2, and the slots 42 are spaced apart along the circumference of the lower cover 3;

[0039] Furthermore, the buckle 41 and the slot 42 are respectively spaced along the circumference of the upper cover 2 and the lower cover 3, which can ensure that the upper cover 2 and the lower cover 3 are subjected to more uniform force when connected, which helps to avoid damage or deformation of the connecting parts due to excessive force at a single point, thereby enhancing the stability and durability of the cup lid body 1.

[0040] Furthermore, the combination of multiple buckles 41 and slots 42 can increase the number of connection points between the upper cover 2 and the lower cover 3, thereby improving the stability of the connection. The multi-point connection method makes the cup lid body 1 less likely to loosen or fall off when subjected to external impact or vibration.

[0041] Preferably, there are four buckles 41 and four slots 42, which are evenly spaced along the circumference of the upper cover 2 and the lower cover 3, respectively.

[0042] like Figures 1 to 7 The lower cover 3 shown includes a first lower cover 31 and a second lower cover 32 sleeved on the outer side wall of the first lower cover 31. The slot 42 is located on the first lower cover 31. An installation mechanism 5 is provided between the first lower cover 31 and the second lower cover 32. The first lower cover 31 is detachably connected to the second lower cover 32 through the installation mechanism 5.

[0043] Optionally, in some embodiments, the mounting mechanism 5 includes a mounting buckle on the first lower cover 31 and a mounting slot on the second lower cover 32, wherein the mounting buckle and the mounting slot are connected to each other so that the first lower cover 31 and the second lower cover 32 are detachably connected.

[0044] Optionally, in some embodiments, the mounting mechanism 5 includes a mounting protrusion on the first lower cover 31 and a mounting hole on the second lower cover 32. The mounting protrusion and the mounting hole are inserted into each other to allow the first lower cover 31 and the second lower cover 32 to be detachably connected.

[0045] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the mounting mechanism 5 includes a mounting slot 51 on the second lower cover 32 and a mounting protrusion 52 on the first lower cover 31. The mounting protrusion 52 and the mounting slot 51 are connected in a slot so that the first lower cover 31 and the second lower cover 32 are detachably connected.

[0046] like Figures 1 to 7 The mounting mechanism 5 shown includes a mounting slot 51 on the second lower cover 32 and a mounting protrusion 52 on the first lower cover 31. The mounting protrusion 52 extends into the mounting slot 51 so that the first lower cover 31 restricts the axial mounting position of the second lower cover 32.

[0047] Furthermore, by setting the mounting slot 51 and the mounting protrusion 52, the user can easily insert the mounting protrusion 52 into the mounting slot 51 through a simple alignment and insertion action, thereby achieving a quick connection between the first lower cover 31 and the second lower cover 32, which helps to simplify the installation process and effectively improve assembly efficiency.

[0048] Furthermore, the connection between the mounting slot 51 and the mounting protrusion 52 effectively prevents unnecessary movement of the second lower cover 32 in the axial direction. Once the mounting protrusion 52 extends into the mounting slot 51, the second lower cover 32 is restricted in the axial direction by the first lower cover 31. This makes it difficult for the first lower cover 31 and the second lower cover 32 to have relative displacement in the axial direction during daily use, which helps to enhance the stability of the connection between the first lower cover 31 and the second lower cover 32.

[0049] Specifically, the second lower cover 32 is fixed to the first lower cover 31 by a slot connecting the mounting protrusion 52 and the mounting groove 51, thereby forming the lower cover 3 as a whole. The inner side wall of the first lower cover 31 is provided with a slot 42, and the inner side wall of the upper cover 2 is provided with a buckle 41. The buckle 41 and the slot 42 engage with each other to make the first lower cover 31 and the upper cover 2 detachably connected.

[0050] like Figures 1 to 7 The buckle 41 shown is integrally formed on the inner sidewall of the upper cover 2;

[0051] Furthermore, there is no connection gap between the integrally formed buckle 41 and the inner wall of the upper cover 2, making the overall structure more stable and helping to prevent the risk of performance degradation or safety hazards caused by the buckle 41 loosening or falling off during use.

[0052] Furthermore, the one-piece molding process ensures the dimensional and shape accuracy of the buckle 41, making the fit between the buckle 41 and the slot 42 tighter and more accurate, which helps to improve the connection stability of the product.

[0053] Furthermore, the one-piece molded buckle 41 eliminates the need for additional assembly steps, which simplifies the production process, helps reduce production costs, and effectively improves production efficiency.

[0054] like Figures 1 to 7 The upper cover 2 shown is provided with a handle mechanism 6 on the side away from the lower cover 3. The handle mechanism 6 includes a handle mounting base 61 fixedly disposed on the upper cover 2, a handle housing 62 detachably connected to the handle mounting base 61, and a handle cover 63 located above the handle housing 62.

[0055] Furthermore, the handle housing 62 is detachably connected to the handle mounting base 61. When the handle housing 62 is damaged, such as by wear or breakage, the user can easily remove it from the handle mounting base 61 for replacement without having to replace the entire upper cover 2 or the handle mechanism 6. Similarly, if the handle cover 63 is damaged, it can also be replaced separately, which helps to reduce maintenance costs.

[0056] Furthermore, the handle mechanism 6 is designed so that users can easily lift the entire cup lid body 1 and the container connected to it, which is beneficial for users to carry or move the cup lid body 1.

[0057] Optionally, the handle mounting base 61 and the handle housing 62 can be connected by threaded connection, slot connection, snap-fit ​​connection, or other connection methods.

[0058] Optionally, the handle housing 62 and the handle cover 63 can be connected by threaded connection, slot connection, snap-fit ​​connection, or other connection methods.

[0059] like Figures 1 to 7 The handle mounting base 61 shown is integrally formed on the surface of the upper cover 2, and a reinforcing rib 611 is provided between the handle mounting base 61 and the surface of the upper cover 2;

[0060] Furthermore, the handle mounting base 61 is integrally formed on the surface of the upper cover 2, which helps to avoid the problem of weak connection that may exist in traditional connection methods such as bonding and screwing. The integral forming makes the handle mounting base 61 and the upper cover 2 a whole, so that when subjected to external force, it will not loosen or separate due to the weakness of the connection part.

[0061] Furthermore, the reinforcing ribs 611 provided between the handle mounting base 61 and the surface of the upper cover 2 further enhance the rigidity of the structure. The reinforcing ribs 611 can effectively disperse the force transmitted to the handle mounting base 61 by the handle mechanism 6 during use, and prevent the handle mounting base 61 and the surface of the upper cover 2 from deforming. Whether it is the pulling force of the handle mechanism 6 during the lifting process or the impact force when subjected to accidental collision, the reinforcing ribs 611 can play a good supporting and dispersing role, thereby improving the stability of the entire structure.

[0062] Specifically, the reinforcing ribs 611 are spaced apart along the circumference of the upper cover 2.

[0063] like Figures 1 to 7 The handle mounting base 61 shown extends toward the handle housing 62 and extends into the handle housing 62. The handle mounting base 61 is provided with a first connecting hole 612, and the handle housing 62 is provided with a second connecting hole 621 that is threadedly connected to the first connecting hole 612.

[0064] Furthermore, the handle mounting base 61 extends towards and into the handle housing 62, enabling precise positioning of the handle mounting base 61 and the handle housing 62 during assembly. During installation, the handle mounting base 61 acts as a positioning guide structure, ensuring that the handle housing 62 is accurately installed in the predetermined position. Simultaneously, the handle housing 62 is firmly fixed to the handle mounting base 61 through the threaded connection between the first connecting hole 612 and the second connecting hole 621. The threaded connection can withstand greater tensile and torsional forces, effectively preventing loosening or detachment between the handle housing 62 and the handle mounting base 61 during daily use, thus ensuring the connection stability of the handle mechanism 6.

[0065] Furthermore, by extending the handle mounting base 61 into the handle housing 62, it is beneficial to hide the connecting parts, making the product's appearance neater and smoother, and improving the overall aesthetics of the cup lid body 1.

[0066] like Figures 1 to 7 The inner wall of the handle housing 62 shown is provided with a handle buckle 622, and the inner wall of the handle cover 63 is provided with a handle groove 631. The handle buckle 622 and the handle groove 631 are engaged to make the handle housing 62 and the handle cover 63 detachably connected.

[0067] Furthermore, the handle buckle 622 and handle slot 631 are designed to make the connection between the handle housing 62 and the handle cover 63 simple and quick. Users do not need to use additional tools or complicated operating steps. They can simply align the handle buckle 622 with the handle slot 631 and press it gently to complete the installation, which helps to improve the convenience of use.

[0068] Furthermore, the tight fit between the handle buckle 622 and the handle slot 631 helps to ensure a stable connection between the handle housing 62 and the handle cover 63, so that the handle mechanism 6 is not easy to loosen or fall off during use, which helps to improve the safety and reliability of the handle mechanism 6.
