Description

Technical Field

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

[0002] Drinking containers are indispensable items in daily life, office and outdoor scenarios. To meet the requirements of portability and sealing, the lids of existing drinking containers usually need to have the function of controlling the water flow to ensure a leak-proof seal when carrying and allow liquid to flow out when in use.

[0003] Currently, common cup lid designs are quite complex, often involving multiple independent components such as springs, rotating valve cores, or locking mechanisms. This not only increases the difficulty of product assembly and production costs but also complicates the operational logic, requiring users to perform multiple steps to switch between lids, thus affecting ease of use. For example, some cup lids require pressing to unlock and then rotating to open the water flow, or pushing the valve core to turn the lid on or off. These multiple steps not only increase the burden on users but are also not user-friendly, especially for the elderly and children. Furthermore, the complex structural design also makes the overall size of the cup lid relatively large, which is detrimental to the portability of the drinking container and fails to adequately meet the user's needs in different scenarios.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains. The terms “first,” “second,” and similar terms used in the specification and claims of this patent application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an” or “a” and similar terms do not indicate a limitation of quantity, but rather indicate the presence of at least one.

[0035] like Figure 1-15 As shown, an embodiment of the present invention discloses a drinking container lid, including an upper lid 1 and a lower lid 2. The lower lid 2 is connected to the cup body and includes a first lid body 21, a first lower sidewall 22 connected to the lower part of the first lid body 21, and a first upper sidewall 23 connected to the upper part of the first lid body 21. The first lower sidewall 22 has a first threaded structure 221 for connecting to the cup body, used to tighten the lower lid 2 onto the cup body. The first lid body 21 has a water inlet channel 211 communicating with a water storage cavity inside the cup, through which liquid in the water storage cavity enters the lid. The water inlet channel 211 includes a water outlet 2111 constructed on the upper side of the lower lid 2, serving as the water outlet of the water inlet channel 211. The upper cover 1 includes a second cover body 11 and a second lower side wall 12 connected to the lower part of the second cover body 11. A drinking channel 111 is arranged in the second cover body 11 as the main path for the user to drink water. The drinking channel 111 includes a drinking port 1111 constructed on the upper side of the upper cover 1 for the user to suck water. The second lower side wall 12 is connected to the first upper side wall 23 through a second threaded structure 7, thereby movably mounting the upper cover 1 on the lower cover 2.

[0036] The upper cover 1 can rotate around the lower cover 2 via the second threaded structure 7, switching between a closed position and a drinking position. In other words, when the user rotates the upper cover 1, guided by the second threaded structure 7, the upper cover 1 can rotate relative to the lower cover 2 around its central axis and switch between a closed position and a drinking position along the axial direction of the cup lid. In the closed position, the water inlet 2111 is disconnected from the drinking channel 111, thereby preventing liquid in the water storage chamber from flowing into the drinking channel 111; in the drinking position, the water inlet 2111 is connected to the drinking channel 111, and liquid in the water storage chamber can enter the drinking mouth 1111 through the water inlet 211. The drinking channel 111 of the upper cover 1 and the water inlet 211 of the lower cover 2 form a complete and unobstructed liquid passage, allowing liquid in the water storage chamber to flow smoothly from the water inlet 211 through the water inlet 211 into the drinking channel 111 and be inhaled by the user through the drinking mouth 1111. Meanwhile, the distance between the upper cover 1 and the lower cover 2 in the closed position is smaller than the distance between them in the drinking position. That is, in the closed position, the relative distance between the upper cover 1 and the lower cover 2 is smaller, blocking or sealing the passage between the drinking channel 111 and the water supply channel 211, thus preventing liquid from being drawn out of the water storage chamber. In the drinking position, the relative distance between the upper cover 1 and the lower cover 2 is larger, forming a sufficient gap or flow channel space. Simultaneously, the drinking channel 111 and the water supply channel 211 are interconnected, forming a continuous passage, allowing liquid to pass smoothly. This structure is compact, reasonable, simple, and convenient. The drinking channel 111 can be opened or closed simply by rotating the upper cover 1. The threaded connection enables rotation and lifting, ensuring smooth movement and reliable positioning, reducing the likelihood of accidental opening or jamming. While ensuring sealing, it significantly reduces the difficulty of operation and is highly practical.

[0037] In this embodiment, the upper cover 1 can rotate along the first direction via the second threaded structure 7 to move from the closed position to the drinking position, and can continue to rotate along the first direction to the unlocked position after reaching the drinking position; in the unlocked position, the upper cover 1 can be separated from the lower cover 2. In other words, the upper cover 1 and the lower cover 2 have three functional states: closed, drinking, and unlocked. The user can achieve the three functions of sealing and closing, normal drinking, and disassembling the upper cover 1 in sequence by continuously rotating the upper cover 1 in the same direction. The operation logic is consistent and the use is more convenient. In the unlocked position, the upper cover 1 can be completely separated from the lower cover 2, which makes it easy for the user to thoroughly clean the drinking channel 111, the water supply channel 211, and the inside of the cup lid, effectively avoiding the growth of bacteria from residual dirt and improving the hygiene of use; at the same time, the detachable structure of the upper cover 1 also makes it easy to replace the parts individually when they are damaged, reducing maintenance costs and extending the overall service life.

[0038] Furthermore, an anti-slip protrusion 122 is arranged on the outer side of the second lower sidewall 12. This anti-slip protrusion 122 is made of a flexible material and has anti-slip stripes on its surface, which increases the friction between the fingers and the upper cover 1, effectively preventing slippage during rotation and improving the stability and smoothness of the opening and closing operation. In other embodiments, the anti-slip protrusion 122 can also be arranged on the outer side of the first cover 21.

[0039] Furthermore, a flexible rubber ring is arranged on the outer side of the first cover 21 to improve the feel and anti-slip effect when the user holds or rotates the device, thereby further enhancing the comfort and operational reliability during use.

[0040] In this embodiment, the cup lid also includes a sealing structure 3, which maintains a relatively fixed connection with the upper cover 1 and can move vertically under the rotation of the upper cover 1. When the upper cover 1 rotates down to the closed position, the sealing structure 3 blocks the passage between the drinking channel 111 and the water supply channel 211, thereby achieving leak-proof operation of the entire cup lid. Specifically, Figure 3-5 The diagram shows cross-sectional views of the upper cover 1 in the closed, drinking, and unlocked positions. When the upper cover 1 rotates down to the closed position, the sealing structure 3 moves with the upper cover 1 to the water inlet 2111 and forms a tight abutment with the water inlet 2111, sealing the water inlet 2111 to prevent liquid in the cup's water storage cavity from entering the cup lid or the outside. When the upper cover 1 rotates up to the drinking position, the sealing structure 3 moves upward with the upper cover 1 and disengages from the water inlet 2111. At this time, the water inlet 2111 is exposed to the air hole, and the sealing structure 3 no longer blocks the water inlet channel, allowing the drinking channel 111 to connect with the water inlet channel 211. When the upper cover 1 rotates down to the unlocked position, the upper cover 1 is completely separated from the lower cover 2, allowing the user to clean the inside of the cup lid. In addition, the drinking channel 111 also includes a water inlet 1112 constructed on the lower side of the upper cover 1. Liquid in the water storage cavity of the cup body enters the drinking channel 111 through the water inlet 1112. Therefore, in some other embodiments, the sealing structure 3 can also be set on the lower cover 2. When the upper cover 1 rotates down to the closed position, the sealing structure 3 and the water inlet 1112 form a tight abutment and fit to seal the water inlet 1112. When the upper cover 1 rotates up to the drinking position, the sealing structure 3 disengages from the water inlet 1112, which can also realize the connection and disconnection of the liquid passage in the cup cover.

[0041] In this embodiment, the lower part of the upper cover 1 is constructed with an upper cavity wall structure 13, and the upper part of the lower cover 2 is constructed with a lower cavity wall structure 24. The upper cavity wall structure 13 and the lower cavity wall structure 24 are connected and surround each other to form a transfer chamber 4, so that the liquid can stay briefly in the cup lid. The upper cavity wall structure 13 can rotate and move up and down relative to the lower cavity wall structure 24. The inlet 1112 is located in the upper cavity wall structure 13 and communicates with the transfer chamber 4. The upper water outlet 2111 is located in the lower cavity wall structure 24 and communicates with the transfer chamber 4. When the upper cover 1 moves to the drinking position, the upper water outlet 2111 communicates with the drinking channel 111 through the transfer chamber 4. The liquid inside the drinking container can flow upward from the internal space of the container through the upper water channel 211 of the lower cover 2 under the user's sucking action, and smoothly enter the interior of the transfer chamber 4. The upper cavity wall structure 13 and the lower cavity wall structure 24 are compatible with each other in terms of structural size, mating position and sealing surface shape, and can be tightly joined in the contact state, so that the liquid is confined in the transfer chamber 4, preventing it from filling the entire inside of the cup lid, which is convenient for subsequent cleaning and maintenance.

[0042] Furthermore, such as Figure 2 As shown, the upper cavity wall structure 13 includes a top wall 131 and a first barrier wall 132 arranged around the top wall 131, with an inlet 1112 located on the top wall 131. The lower cavity wall structure 24 includes a base 241 and a second barrier wall 242 arranged around the base 241, with an upper water inlet 2111 located on the base 241. The first barrier wall 132 and the second barrier wall 242 are partially sleeved and can move relative to each other, and the height of the first barrier wall 132 and / or the second barrier wall 242 is configured such that when the upper cover 1 and the lower cover 2 are displaced to the maximum distance relative to each other, the first barrier wall 132 and the second barrier wall 242 still remain in contact, so that during the process of the upper cover 1 moving from the closed position to the drinking position, the transfer chamber 4 only allows liquid to enter and exit through the inlet 1112 and the upper water inlet 2111, while the rest of the parts remain sealed. A flexible sealing ring 15 is arranged on the second barrier wall 242, and the second barrier wall 242 is sleeved with the first barrier wall 132 through the flexible sealing ring 15 to form a stable and reliable sealing fit, effectively improving the sealing performance between the channels and preventing liquid leakage and cross-contamination. In some other embodiments, the flexible sealing ring 15 is disposed on the first barrier wall 132, and the first barrier wall 132 is sleeved with the second barrier wall 242 through the flexible sealing ring 15.

[0043] Furthermore, the flexible sealing ring 15 has multiple layers of flexible ribs integrally formed on its outer side to increase the contact pressure between the flexible sealing ring 15 and the inner wall of the first barrier wall 132, effectively preventing liquid leakage.

[0044] In this embodiment, as Figure 2As shown, the sealing structure 3 includes a plug 31 and a connecting frame 32. The upper end of the connecting frame 32 is connected to the upper cavity wall structure 13, and the lower end is connected to the plug 31, so that the plug 31 can move synchronously with the upper cover 1. The plug 31 is a columnar or plug-shaped structure that matches the shape of the water inlet 2111. A flexible sealing sleeve can be fitted on its outer side to ensure a tight fit and reliable seal with the water inlet 2111 when closed. In addition, there is a water passage space between the connecting frame 32 and the water inlet 1112, so that the drinking channel 111 is connected to the transfer chamber 4, ensuring that the liquid temporarily stored in the transfer chamber 4 can flow smoothly into the drinking channel 111, realizing the stable output of liquid and meeting the user's drinking water needs. When the top cover 1 is rotated to the closed position, the plug 31 enters the water inlet channel 211 and blocks the water outlet 2111; when the top cover 1 is rotated to the drinking position, the plug 31 separates from the water outlet 2111, and the liquid in the water inlet channel 211 can enter the drinking channel 111 through the transfer chamber 4 and the water space.

[0045] Furthermore, such as Figure 6 As shown, the connecting frame 32 includes two connecting parts 321 and a mounting part 322. One end of the connecting part 321 is connected to the mounting part 322, and the other end is connected to the upper cavity wall structure 13, so that the mounting part 322 spans across the inlet 1112 through the two connecting parts 321 without obstructing the flow section of the inlet 1112. At the same time, the lower end of the mounting part 322 is connected to the plug 31, and through the connecting frame 32, the plug 31 achieves synchronous linkage with the upper cover 1.

[0046] Furthermore, such as Figure 8 As shown, two connectors 321 are symmetrically arranged on both sides of the mounting component 322, and the two connectors 321 are connected by a connecting plate 323. The thickness of the connecting plate 323 is less than the thickness of the two connectors 321, thereby forming a stepped water passage between the two sides of the connecting plate 323 and the connectors 321. This water passage is connected to the water passage of the cover. When the liquid flows through the inlet 1112, it is guided to pass smoothly along the stepped passage, effectively reducing fluid resistance and avoiding the generation of eddies.

[0047] In this embodiment, as Figure 7As shown, the upper cover 1 also includes a drinking spout assembly 5, which is detachably connected to the upper cover 1 for easy disassembly, cleaning, and replacement by the user. Specifically, the drinking spout assembly 5 includes a connecting base 51 and a drinking spout 52 mounted on the upper part of the connecting base 51; the upper cover 1 has an installation channel 14 extending through the upper and lower sides of the upper cover 1, and the connecting base 51 is detachably connected to the installation channel 14 via a snap-fit ​​structure 6, thereby installing the drinking spout 52 on the upper cover 1. During installation, the user aligns the connecting base 51 of the drinking spout assembly 5 with the installation channel 14 of the upper cover 1, applies pressure or rotates it through the snap-fit ​​structure 6, and securely engages the connecting base 51 with the installation channel 14 to complete the installation; during disassembly, the user only needs to release the locking state of the snap-fit ​​structure 6 to remove the drinking spout assembly 5 from the installation channel 14, making the operation simple and quick.

[0048] Furthermore, the drinking channel 111 is arranged inside the drinking spout assembly 5, so the drinking spout 52 has a drinking port 1111 at the top and a water inlet 1112 at the bottom.

[0049] Furthermore, the upper end of the connecting bracket 32 ​​is connected to the lower part of the connecting base 51 of the spout assembly 5, thereby forming a tight whole between the spout assembly 5 and the sealing structure 3. This not only saves installation space but also improves the integration of components. The connecting bracket 32 ​​also features an operating surface extending away from the spout 52. This operating surface is located in the stepped water passage area and is specifically formed on part of the surfaces of the connecting member 321 and the connecting plate 323, providing the user with a clear point of force application. When disassembling or installing the spout assembly 5, the user can easily disassemble the spout assembly and the sealing structure 3 by applying force to the operating surface, making the disassembly and assembly process more effortless and convenient.

[0050] In this embodiment, the drinking spout 52 also includes a mouthpiece body 521 located on the upper part of the upper cover 1 and a mounting seat 522 located in the mounting channel 14, with the mounting seat 522 connected to the bottom of the mouthpiece body 521. The outer side of the drinking spout 52 is made of a flexible polymer material, which not only improves the user's drinking comfort and fit but also enhances the sealing effect between the drinking spout 52 and the mounting channel 1411, effectively preventing leakage during use.

[0051] Furthermore, such as Figure 8As shown, the mounting base 522 consists of an inner rigid support part 522a and an outer flexible covering part 522b. The rigid support part 522a, the connecting base 51, and the sealing structure 3 below the connecting base 51 are integrally injection molded from the same material. The flexible covering part 522b is integrally molded with the nozzle body 521. This allows the lower support and sealing structure to be used for a long time without replacement, while the upper nozzle body, which comes into contact with the human body, can be replaced separately after long-term use or wear. This design ensures structural strength and installation stability while improving hygiene, facilitating component replacement, and reducing operating costs.

[0052] Furthermore, such as Figure 9 , Figure 10 As shown, the mounting base 522 includes a first sealing seat 5221 and a second sealing seat 5222. The upper and lower sides of the first sealing seat 5221 are connected to the mouthpiece body 521 and the second sealing seat 5222, respectively. The mounting channel 14 includes a first connecting channel 141. The periphery of the first sealing seat 5221 abuts against the inner wall of the first connecting channel 141, and the upper side of the second sealing seat 5222 abuts against the lower part of the periphery of the first connecting channel 141. The radial dimension of the first sealing seat 5221 is smaller than the radial dimension of the second sealing seat 5222. When the mouthpiece 52 passes through the mounting channel 14, the mounting base 522 and the mounting channel 14 form a stepped sealing fit, further improving the sealing reliability after assembly. Simultaneously, it positions and supports the mouthpiece 52, ensuring the stability of the assembled structure.

[0053] Furthermore, the lower part of the periphery of the first connecting channel 141 has a downwardly protruding first convex ring 1411, and the upper side of the second sealing seat 5222 has a sealing groove 5223 that matches the first convex ring 1411; when the drinking spout assembly 5 is installed on the upper cover 1, the first convex ring 1411 is engaged in the sealing groove 5223. The engagement between the first convex ring 1411 and the sealing groove 5223 forms a circumferential sealing structure between the cover and the drinking spout 52, effectively preventing liquid leakage from the assembly gap and improving the overall sealing performance.

[0054] Furthermore, the upper side of the second sealing seat 5222 has an upwardly protruding second convex ring 5224, and the sealing groove 5223 is formed by the inner wall of the second convex ring 5224 and the outer wall of the first sealing seat 5221. When the first convex ring 1411 is engaged in the sealing groove 5223, the second convex ring 5224 and the outer wall of the first sealing seat 5221 are tightly fitted to both sides of the first convex ring 1411, forming a clamping effect, making the structure of this area compact, ensuring a stable and reliable sealing position, and automatically aligning during assembly, further improving the ease of installation.

[0055] In this embodiment, as Figure 7As shown, the snap-fit ​​structure 6 includes a matching snap-fit ​​assembly 61 and a snap-fit ​​protrusion 62. The snap-fit ​​assembly 61 is mounted on the upper cover 1, and the snap-fit ​​protrusion 62 is mounted on the connecting base 51. The two cooperate with each other to achieve the disassembly and fixation of the drinking spout assembly 5 and the upper cover 1. In some other embodiments, the snap-fit ​​assembly 61 may also be mounted on the connecting base 51, and the snap-fit ​​protrusion 62 may be mounted on the upper cover 1.

[0056] Furthermore, such as Figure 10 As shown, the installation channel 14 also includes a second connecting channel 142, and a slot assembly 61 is arranged on the inner wall of the second connecting channel 142. The slot assembly 61 includes a guide groove 621 and a snap-fit ​​groove 622 communicating with the guide groove 621. A snap-fit ​​protrusion 62 is arranged around the connecting base 51, and the snap-fit ​​protrusion 62 can enter the snap-fit ​​groove 622 through the guide groove 621. Specifically, the guide groove 621 extends axially upward from the bottom of the inner wall of the second connecting channel 142, and the snap-fit ​​groove 622 communicates with the guide groove 621 and extends circumferentially along the second connecting channel 142. During installation, the snap-fit ​​protrusion 62 enters the guide groove 621 axially and rotates circumferentially into the snap-fit ​​groove 622, thereby locking the spout assembly 5 with the cap. The guide groove 621 facilitates the smooth entry of the snap-fit ​​protrusion 62 into the assembly position, and the snap-fit ​​groove 622 can reliably limit and fix the snap-fit ​​protrusion 62. The user can operate easily and quickly during installation and disassembly, and at the same time, it can realize a stable and reliable detachable connection between the connecting base 51 and the cover.

[0057] In this embodiment, as Figure 10 As shown, the upper cover 1 also includes a cover shell 110 and a mounting base 120 disposed inside the cover shell 110; a first connecting channel 141 is arranged on the cover shell 110, and a second connecting channel 142 and a slot assembly 61 are both arranged on the mounting base 120. The first connecting channel 141 and the second connecting channel 142 are aligned with each other to form a mounting channel 14 through which the drinking spout 52 passes.

[0058] In this embodiment, as Figure 11As shown, the mounting base 120 and the cover shell 110 are detachably connected, and both are provided with at least one set of mutually cooperating connection structures 130. Specifically, the connection structure 130 includes a first connection structure 1301 and a second connection structure 1302. The first connection structure 1301 includes at least one latch 1301a disposed on the upper edge of the mounting base 120, and a protrusion 1301b disposed on the inner surface of the cover shell 110 and adapted to the latch 1301a; the latch 1301a can engage with the protrusion 1301b to limit the displacement of the cover shell 110 relative to the mounting base 120. The second connection structure 1302 includes at least one guide rib 1302a disposed on the inner surface of the cover shell 110 and surrounding the first connection channel 141, and a limiting groove 1302b disposed on the slot assembly 61 and adapted to the guide rib 1302a; the guide rib 1302a can engage with the limiting groove 1302b to further strengthen the connection strength between the two.

[0059] In this embodiment, as Figure 12 As shown, the inlet 2111 is shaped like a trumpet, wider at the top and narrower at the bottom, and has a sealing part 211a that is adapted to the shape of the plug 31. Specifically, the base 241 of the lower cavity wall structure 24 is provided with a platform portion 241a that is recessed towards the interior of the transfer chamber 4. The upper water inlet 2111 is opened in the recessed area of ​​the platform portion 241a and is in the shape of a trumpet, which is larger at the top and smaller at the bottom. The bottom periphery of the upper water inlet 2111 is provided with a limiting edge 2112 for radially limiting the sealing element of the sealing structure 3. The limiting edge 2112 and the inner wall of the trumpet-shaped upper water inlet 2111 together form a sealing portion 211a. In this way, the trumpet-shaped structure, which is larger at the top and smaller at the bottom, provides an automatic guiding and centering effect for the downward pressing and sealing action of the plug 31, avoiding problems such as misalignment of the plug 31 during the sealing process. At the same time, the limiting edge 2112 of the upper water inlet 2111 forms a full circumferential limit on the plug 31, ensuring that the plug 31 and the sealing mating surface are accurately aligned and pressed together, thereby enhancing the sealing effect of the cup lid.

[0060] In this embodiment, in order to achieve airflow balance when the cup lid is opened for drinking, avoid negative pressure inside the container that would cause drinking difficulties, and ensure sealing performance when closed, an air guide hole 212 is arranged on the outer side of the second barrier wall 242 of the first lid 21, penetrating the upper and lower sides of the first lid 21. The vent 212 is located within the coverage area of ​​the first barrier wall 132. At this time, the first barrier wall 132 is arranged close to the outside of the second barrier wall 242 and above the vent 212. When the upper cover 1 is rotated to the drinking position, the upper cover 1 moves the first barrier wall 132 upward, causing the first barrier wall 132 to separate from the vent 212. The vent 212 is in an open state, and the outside air can enter the drinking container through the vent 212 to balance the air pressure inside and outside the container and ensure that the liquid flows out smoothly. When the upper cover 1 is rotated to the closed position, the first barrier wall 132 moves downward with the upper cover 1 and presses tightly against the end face of the vent 212 to form a seal and block the vent 212, preventing the liquid inside the container from leaking through the vent and preventing external impurities from entering. In other embodiments, the air vent 212 may also be arranged at other positions outside the second barrier wall 242. In this case, a sealing ring 15 corresponding to the position of the air vent 212 is provided outside the first barrier wall 132. When the upper cover 1 is in the closed position, the sealing ring 15 fits tightly with the periphery of the air vent 212, further improving the sealing effect at the position of the air vent 212.

[0061] In this embodiment, as Figure 2 As shown, the second threaded structure 7 includes a helical guide groove 71 and a sliding guide portion 72 adapted to the helical guide groove 71. The helical guide groove 71 is located on the outer side of the first upper sidewall 23, and the sliding guide portion 72 is located on the inner side of the second lower sidewall 12. The sliding guide portion 72 can move along the helical guide groove 71 to drive the upper cover 1 to rotate and rise relative to the lower cover 2. When the sliding guide portion 72 moves from the front end to the rear end along the helical guide groove 71, it drives the upper cover 1 to rotate relative to the lower cover 2 and rise upwards away from the lower cover 2. Through the relative movement of the sliding guide portion 72 along the helical guide groove 71, the upper cover 1 can be stably driven to achieve the linkage action of rotation and lifting, ensuring a smooth and stable opening and closing process. In some other embodiments, the helical guide groove 71 can also be located on the inner side of the second lower sidewall 12. In this case, the sliding guide portion 72 is located on the outer side of the first upper sidewall 23. Similarly, the sliding guide portion 72 can move along the helical guide groove 71 to drive the upper cover 1 to rotate and rise relative to the lower cover 2.

[0062] Specifically, such as Figure 13 , Figure 14 As shown, Figure 13 The positional relationship between the spiral guide groove 71 and the sliding guide part 72 is shown when the upper cover 1 is in the closed position; Figure 14The diagram shows the positional relationship between the spiral guide groove 71 and the sliding guide portion 72 when the top cover 1 is in the drinking position. The sliding guide portion 72 is trapezoidal, having two relatively parallel inclined surfaces and a horizontal surface. The spiral guide groove 71 consists of a connected inclined slide groove 71a and a horizontal slide groove 71b, with the two inclined surfaces of the sliding guide portion 72 parallel to the two sides of the inclined slide groove 71a, and its horizontal surface parallel to the horizontal slide groove 71b. When the top cover 1 is in the closed position, the sliding guide 72 is completely located within the inclined slide groove 71a, and the inclined surfaces on both sides of the inclined slide groove 71a tightly clamp the inclined surfaces on both sides of the sliding guide 72. Under the action of external force, the sliding guide 72 slides along the inclined slide groove 71a and gradually enters the horizontal slide groove 71b until the top cover 1 is rotated to the drinking position, at least a part of the sliding guide 72 enters the horizontal slide groove 71b, and the horizontal surface of the sliding guide 72 is aligned with the horizontal slide groove 71b, thereby realizing the rotation and lifting of the top cover 1 relative to the bottom cover 2 through the cooperation of the spiral guide groove 71 and the sliding guide 72.

[0063] In this embodiment, the second threaded structure 7 further includes a limiting component 73, which limits the rotational stroke of the upper cover 1, ensuring that the upper cover 1 is stably positioned in the drinking position and preventing it from dislodging due to excessive rotation. Specifically, the limiting component 73 includes a first protrusion 731 disposed at the rear end of the spiral guide groove 71 and a second protrusion 732 disposed on the inner side of the first sidewall; when the second protrusion 732 moves to the first protrusion 731, the upper cover 1 is in the drinking position. In other words, when the second protrusion 732 rotates with the upper cover 1 to contact the first protrusion 731, it indicates that the upper cover 1 is in the drinking position, achieving precise indication and limiting of the end point of the stroke.

[0064] Furthermore, such as Figure 15 As shown, the first protrusion 731 includes an extrusion groove 7311 arranged on the side wall of the lower cover 2 at the end of the spiral guide groove 71 and a protrusion 7312 arranged on the outside of the groove wall of the extrusion groove 7311; the protrusion 7312 has a certain elastic deformation capability, and can shrink towards the groove of the extrusion groove 7311 after being squeezed by the second protrusion 732, thereby playing a role in buffering and guiding.

[0065] Furthermore, the protrusion 7312 of the first protrusion 731 is provided with a first ridge 7312a, a recess 7312b, and a second ridge 7312c in sequence along the circumferential direction. When the upper cover 1 is rotated to the furthest distance from the lower cover 2, the second protrusion 732 engages in the recess 7312b. At this time, the first ridge 7312a and the second ridge 7312c are located on both sides of the circumference of the first protrusion 731, forming a stable engagement limit.

[0066] Furthermore, the height of the first protrusion 7312a is lower than the height of the second protrusion 7312c. When the upper cover 1 rotates from the closed position to the farthest position along the first direction, the second protrusion 732 first contacts the lower first protrusion 7312a. Due to its smaller height, the second protrusion 732 can smoothly pass over the first protrusion 7312a with less resistance and slide into the recess 7312b, achieving easy locking. However, when the upper cover 1 continues to rotate along the first direction, the second protrusion 732 needs to overcome the obstruction of the higher second protrusion 7312c, making it difficult for the second protrusion 732 to come out of the recess 7312b, thereby effectively preventing the upper cover 1 from rotating excessively and achieving unidirectional limiting.

[0067] Furthermore, if the user continues to apply rotational force to the upper cover 1 in the first direction, the second protrusion 732 can also pass over the second protrusion 7312c. At this time, the second protrusion 732 rotates with the upper cover 1 and passes over the first protrusion 731, and the upper cover 1 enters the unlocked state. In the unlocked state, the upper cover 1 can be separated from the lower cover 2, the limiting relationship between the second protrusion 732 and the spiral guide groove 71 is released, and the upper cover 1 is completely removed, thereby achieving quick disassembly and making it convenient for the user to clean and maintain the inside of the cup lid.

[0068] In this embodiment, the upper cover 1 further includes a third lower sidewall 16 arranged annularly inside the second lower sidewall 12. The second lower sidewall 12 and the third lower sidewall 16 clamp together to form a rotation space. The first upper sidewall 23 is at least partially installed within the rotation space, thereby achieving clamping and improving sealing performance. The sealing structure 3 is installed inside the second lower sidewall 12.

[0069] Another embodiment of the present invention discloses a cup, including a cup body and a drinking container lid as described above.
