Description

Technical Field

[0001] This utility model relates to the field of cup lids, specifically a cup lid with a spout. Background Technology

[0002] As a core component of drinking utensils, the structural design of water bottle lids directly affects the product's functionality and user experience. Currently, water bottle lids on the market are mainly divided into two categories: sealing lids without spouts. These lids primarily function to seal the cup opening, typically using screw-on or snap-on seals. When drinking, the liquid must be poured into another container (such as the cup opening or a straw) or poured directly into the bottle. Typical applications include traditional insulated cups and office water bottles. Their design aims to ensure the airtightness and portability of liquid storage, but lacks a convenient structure for direct drinking. Functional lids with spouts, designed to meet the need for direct drinking, often include a spout in children's water bottles, sports water bottles, and outdoor water bottles. Currently, the mainstream straw material is flexible, such as rubber. It connects to the cup lid body through molding or an embedded structure to achieve functions such as sucking water and preventing leaks. After use, a pressure cap component bends and presses the straw to achieve a seal and storage. However, this method has the following drawbacks: insufficient durability. Flexible straws are prone to softening, hardening, cracking, or deformation after prolonged contact with high-temperature liquids (such as hot water), detergents, or frequent use. For example, the bite-shaped part expands and deforms due to repeated biting, reducing the seal and causing leaks; the internal flow channel of the straw changes due to deformation, leading to increased suction resistance or abnormal liquid flow rate; after long-term use, the straw has poor environmental adaptability; in low-temperature environments, the rubber hardens and becomes brittle, potentially producing debris; in high-temperature environments, it softens and deforms, causing leaks at the connection between the straw and the cup lid. Furthermore, to ensure the straw automatically springs back to a sucking state during use, the flexible nozzle needs a certain degree of elasticity. While this facilitates the springback, it also makes storing the straw after use cumbersome. Therefore, a cup lid with a built-in straw is essential. Utility Model Content

[0003] The purpose of this invention is to provide a cup lid with a spout, which allows the spout to be stored or released without deformation, improving durability and ease of operation, thereby solving the technical defects and unmet technical requirements of the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cup lid with a spout, comprising:

[0005] A cup lid, wherein the cup lid is provided with a first groove, a second groove, a third groove and a fourth groove, the first groove is formed at the top of the cup lid, the second groove is formed on the side wall of the cup lid, the third groove is formed at the bottom of the first groove, the fourth groove is formed at the bottom of the third groove and extends downward through the cup lid to the bottom of the cup lid, and a straw is provided in the fourth groove, and the first groove, the second groove, the third groove and the fourth groove are interconnected;

[0006] The suction nozzle has a connecting end, a free end, and a fluid channel. The connecting end and the free end are located at opposite ends of the suction nozzle. The fluid channel is located inside the suction nozzle, with its openings on the free end and the connecting end, respectively. The connecting end is rotatably connected to the inner wall of the first or third groove, ensuring it always fits and covers the upper surface of the straw. Further explanation is needed: without a mounting base, the connecting end fits and rotatably connects to the bottom wall of the third groove, covering it. The outline of the upper surface of the straw conforms to the bottom wall of the third groove, ensuring a complete bottom wall outline. If a mounting base is provided (as described below), the connecting end fits and rotatably connects to the top of the end of the mounting base with the first mounting hole, covering the top of this portion of the mounting base. This top portion of the mounting base conforms to the bottom wall outline of the third groove.

[0007] The bottom of the first groove is provided with an air pressure balance hole, which penetrates the cup lid;

[0008] In the initial state, the nozzle is located in the first and third grooves, with its upper end flush with the top of the cup lid and its lower end abutting against the bottom of the first groove;

[0009] In use, the free end is located outside the first groove, and the opening on the connecting end of the fluid channel is connected to the straw.

[0010] In this application, it is necessary to further explain that the initial state is when the nozzle is stored in the cup lid, that is, the free end is in the first groove. In the use state, the nozzle is rotated so that the free end rotates around the connecting end and rotates out of the first groove. When the opening on the connecting end of the fluid channel is connected to the upper end of the straw, it is in the use state. In addition, the air pressure balance hole penetrating the cup lid means that the upper opening of the air pressure balance hole is opened at the bottom of the first groove, and the lower opening is opened at the bottom of the cup lid.

[0011] In addition, regarding the interconnection between the first, second, third, and fourth slots mentioned above, it needs to be specifically explained that the first slot is connected to the second slot, the first slot is connected to the third slot, and the fourth slot is connected to the third slot, while the second slot is not directly connected to the third slot. The second slot needs to be connected to the third slot through the first slot.

[0012] Preferably, the nozzle is further provided with a pressing member, which is located at the end of the nozzle away from the free end, and the connecting end is located below the pressing member;

[0013] In use, the pressing member is located in the second groove, and the bottom of the pressing member in the initial state can abut against the inner wall of the second groove.

[0014] It should be noted in this application that the top of the pressing member is at least flush with the top of the cup lid, and there is space between the pressing member and the bottom of the first groove at the same horizontal level. Therefore, the pressing member has enough space to rotate when the connecting end rotates. The above-mentioned connection end being below the pressing member refers to the horizontal level of the center of the connection end being below the horizontal level of the pressing member. It does not mean that the connection end is directly below the pressing member. It can be understood that the center of the connecting member is lower than the center of the pressing member in the vertical direction, and in the horizontal direction, the center of the connecting member is located between the center of the pressing member and the center of the free end. In addition, when switching between the initial state and the use state, the pressing member is positioned so that the end of the pressing member away from the free end is in the second groove, that is, the lower end face of the pressing member in the initial state can abut against the inner wall of the second groove.

[0015] Preferably, the nozzle is also provided with a dust plug, which is located at the bottom of the nozzle between the connecting end and the free end, and can block the air pressure balance hole.

[0016] Preferably, it includes a mounting base, the mounting base including a main body, a first mounting member and a second mounting member, the first mounting member and the second mounting member being located at opposite ends of the main body and both located on the lower end face of the main body, the top of the main body having a first connecting hole and a second connecting hole, the first connecting hole penetrating downward through the first mounting member, and the second connecting hole penetrating downward through the second mounting member;

[0017] The cup lid is also provided with a fifth groove, which is located at the bottom of the first groove and on the inner wall of the third groove, and covers the fourth groove, and is connected to the first groove, the third groove and the fourth groove respectively.

[0018] The first mounting piece is fitted into the fourth groove, with its lower end snapped into the bottom of the cup lid and its upper end snapped into the abutment of the fifth groove. The upper end of the straw is fitted into the first connecting hole, and the dust plug can be installed in the second connecting hole.

[0019] The second mounting piece is fitted into the air pressure balance hole, with its lower end snapped into the bottom of the cup lid and its upper end snapped into the air pressure balance hole;

[0020] The main body is disposed in the fifth groove, and the top position of the first connecting hole on the main body is connected to the inner wall of the third groove and is rotatably connected to the connecting end.

[0021] In this application, the first connecting hole and the second connecting hole respectively penetrate the first mounting part and the second mounting part. This can be understood as the lower opening of the first connecting hole being located on the lower end face of the first mounting part, and the lower opening of the second mounting hole being located on the lower end face of the second mounting part. In addition, the dust plug blocks the air pressure balance hole by sealing the second connecting hole. Since the main body abuts against the bottom of the first groove, and the second mounting part is fitted inside the air pressure balance hole, the second connecting hole at this time functions as an air pressure balance hole to balance the air pressure. The fitting of the second mounting part is also tight. Similarly, the first mounting part is also tightly fitted in the fourth groove, which is equivalent to "replacing" the fourth groove to realize the function of installing the straw and connecting the space between the cup and the lid.

[0022] The connection between the fifth slot and the main body in this application can be understood as follows: since the fifth slot is located at the bottom of the first and third slots, and the main body is located in the fifth slot, after the main body is installed in the fifth slot, the main body can fill the original fifth slot flush with it. That is, the main body can be installed in the fifth slot, and the bottom of the first and third slots can be restored to the outline shape before the fifth slot was opened. Therefore, the original connecting end is in rotational contact with the third slot, and at this time the connecting end will also be in rotational contact with the upper surface of the main body. The lower surface of the nozzle, which was originally in the initial position, is against the bottom of the first slot, and at this time it will also be against the top of the main body.

[0023] In addition, since the fourth slot is also located at the bottom of the third slot, and the fifth slot is also located at the bottom of the fourth slot, the bottom of the fifth slot will cover part of the opening of the fourth slot at the bottom of the third slot. In other words, it can be understood that the order from top to bottom is the third slot, the fifth slot, and the fourth slot, and the three are connected in sequence.

[0024] In this application, the mounting base is made of a flexible material, such as rubber. Furthermore, an annular groove is formed outside the opening of the first connecting hole on the top of the mounting base, so that the opening of the first connecting hole on the top of the mounting base is separated from the top surface of the mounting base. This allows the connecting end to better fit with the opening of the first connecting hole on the top of the mounting base, further ensuring the connection between the fluid channel and the suction tube.

[0025] Preferably, the surface of the connecting end is set as an ellipsoid, and rotating connectors are provided on both sides of the connecting end;

[0026] A rotating connection hole is provided on the inner wall of the first groove or the inner wall of the third groove;

[0027] The rotating connector is fitted inside the rotating connection hole, and the rotating connector can rotate within the rotating connection hole.

[0028] What needs further explanation in this application is that the position of the rotating connection hole can be on the first inner sidewall, on the inner sidewall of the third groove, or partly on the inner sidewall of the first groove and partly on the inner sidewall of the third groove, as long as the connection end can be rotatably connected with the inner wall of the third groove. That is, in this application, a part of the connection end is always located in the third groove and rotatably connected with the inner wall of the third groove.

[0029] Preferably, the rotating connector is provided with an inclined surface, which extends from the side of the rotating connector to the end face of the rotating connector away from the connecting end.

[0030] Preferably, the cup lid is also provided with a handle, which is rotatably connected to the cup lid.

[0031] In this application, the cup lid and the handle can be rotatably connected by providing two opposite holes on both sides of the cup lid and installing connectors on both ends of the handle. Alternatively, two connectors can be provided on both sides of the cup lid and two holes can be provided on both ends of the handle. The holes on the handle can be fitted onto the two connectors, allowing them to rotate relative to each other. The specific connection method is not limited.

[0032] Preferably, the radial dimension of the cross-section of the fluid channel at the connecting end is smaller than the radial dimension of the cross-section of the fluid channel at the free end.

[0033] Preferably, the bottom of the cup lid is provided with a first extension and a second extension, both of which have annular cross-sections. The second extension is fitted inside the first extension. The openings of the fourth groove and the air pressure balance hole at the bottom of the cup lid are both located in the inner circle of the second extension. There is a space between the first extension and the second extension to accommodate the cup opening.

[0034] In this application, the above content can be understood as follows: the inner wall of the cup's rim is fitted outside the second extension, and the first extension is fitted outside the outer wall of the cup's rim. This is equivalent to placing the cup wall at the cup's rim between the first and second extensions. The connection method between the cup lid and the cup rim is not specifically limited here.

[0035] Preferably, the inner wall of the first extension is provided with an internal thread, or the outer wall of the second extension is provided with an external thread, and the cup lid is connected to the cup by a threaded connection.

[0036] In this application, it should be further explained that in the above-mentioned connection between the cup lid and the cup via a threaded connection, the thread is the internal thread on the first extension or the external thread on the second extension. It can be understood that the connection between the cup lid and the cup is established through the thread on the first extension or the second extension.

[0037] Compared with the prior art, the beneficial effects of this utility model are:

[0038] 1. This application separates the straw and the nozzle, and rotates the nozzle onto the cup lid. By rotating the nozzle, the fluid channel can be connected and disconnected from the straw, avoiding deformation and bending of the straw and making it easy to store. The second groove and the pressing part provide good rotation space for the pressing part, while the inner wall of the second groove can limit and abut the pressing part to prevent excessive rotation of the nozzle and ensure the connection between the fluid channel and the straw. The pressing part also makes the rotation of the nozzle more convenient. The mounting base can better connect the nozzle and the straw and also make it easier to disassemble and clean the whole.

[0051] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0052] Please see Figure 1-10 Embodiments of this utility model:

[0053] Example:

[0054] like Figure 1 , 2 As shown in Figures 3, 4, 5, 7, and 8: A cup lid 1 with a spout 3, comprising:

[0055] A cup lid 1 is provided with a first groove 4, a second groove 5, a third groove 6, and a fourth groove 7. The first groove 4 is located at the top of the cup lid 1, the second groove 5 is located on the side wall of the cup lid 1, the third groove 6 is located at the bottom of the first groove 4, and the fourth groove 7 is located at the bottom of the third groove 6 and extends downward through the cup lid 1 to the bottom of the cup lid 1. A straw 2 is provided in the fourth groove 7. The first groove 4, the second groove 5, the third groove 6, and the fourth groove 7 are interconnected.

[0056] The suction nozzle 3 is provided with a connecting end 8, a free end 9 and a fluid channel 11. The connecting end 8 and the free end 9 are located at opposite ends of the suction nozzle 3. The fluid channel 11 is located inside the suction nozzle 3, with its openings located on the free end 9 and the connecting end 8 respectively. The connecting end 8 is rotatably connected to the inner wall of the first groove 4 or the third groove 6, and can always fit and cover the upper end face of the straw 2.

[0057] The bottom of the first groove 4 is provided with an air pressure balance hole 10, which penetrates the cup lid 1;

[0058] In the initial state, the nozzle 3 is located in the first groove 4 and the third groove 6, with its upper end flush with the top of the cup lid 1 and its lower end abutting against the bottom of the first groove 4;

[0059] In use, the free end 9 is located outside the first groove 4, and the opening on the connecting end 8 of the fluid channel 11 is connected to the straw 2.

[0060] In this embodiment, the straw 2 and the nozzle 3 are set separately, and the nozzle 3 is rotated and set on the cup lid 1. By rotating the nozzle 3, the fluid channel 11 is connected and disconnected from the straw 2, avoiding deformation and bending of the straw 2, and making it easy to store.

[0061] like Figure 7-8 As shown: The suction nozzle 3 is also provided with a pressing member 12, which is located at the end of the suction nozzle 3 away from the free end 9, and the connecting end 8 is located below the pressing member 12; in the use state, the pressing member 12 is located in the second groove 5, and the bottom of the pressing member 12 in the initial state can abut against the inner wall of the second groove 5.

[0062] In this embodiment, the second groove 5 and the pressing member 12 are provided. The second groove 5 provides better rotation space for the pressing member 12, and at the same time, it can limit and abut the pressing member 12 through its inner wall, so as to avoid excessive rotation of the suction nozzle 3 and ensure the connection between the fluid channel 11 and the fluid. The setting of the pressing member 12 also makes the rotation of the suction nozzle 3 more convenient.

[0063] like Figure 2 , 7 As shown in Figure 8: The suction nozzle 3 is also provided with a dust plug 13, which is located at the bottom of the suction nozzle 3, between the connecting end 8 and the free end 9, and can block the air pressure balance hole 10.

[0064] like Figure 2 , 9As shown in Figure 10: It includes a mounting base 14, which includes a main body 15, a first mounting member 16 and a second mounting member 17. The first mounting member 16 and the second mounting member 17 are located at both ends of the main body 15 and are both located on the lower end face of the main body 15. The top of the main body 15 is provided with a first connecting hole 18 and a second connecting hole 19. The first connecting hole 18 penetrates downward through the first mounting member 16, and the second connecting hole 19 penetrates downward through the second mounting member 17.

[0065] The cup lid 1 is also provided with a fifth groove 20, which is located at the bottom of the first groove 4 and on the inner wall of the third groove 6, and covers the top of the fourth groove 7, and is connected to the first groove 4, the third groove 6 and the fourth groove 7 respectively.

[0066] The first mounting component 16 is fitted into the fourth groove 7, with its lower end snapped into the bottom of the cup lid 1 and its upper end snapped into the bottom of the fifth groove 20. The upper end of the straw 2 is fitted into the first connecting hole 18, and the dust plug 13 can be installed in the second connecting hole 19.

[0067] The second mounting component 17 is fitted into the air pressure balance hole 10, with its lower end snapped into the bottom of the cup lid 1 and its upper end snapped into the air pressure balance hole 10.

[0068] The main body 15 is disposed in the fifth groove 20, and the top position of the first connecting hole 18 on the main body 15 is connected to the inner wall of the third groove 6 and is rotatably connected to the connecting end 8.

[0069] In this embodiment, the mounting base 14 allows for better connection between the nozzle 3 and the straw 2, and also enables better disassembly and cleaning. Furthermore, in the initial state, the lower end of the nozzle 3 covers the air pressure balance hole 10, and the dust plug 13, through its connection to the second connection hole 19, further ensures that dust is better prevented from entering the water cup when the nozzle is not in use.

[0070] Specifically, in this embodiment, the structure related to the above-mentioned snap-fit ​​relationship is as follows: as shown in the figure, both the fourth groove 7 and the air pressure balance hole 10 are through-holes, which can be understood as holes. Therefore, the lower end of the fourth groove 7 and both ends of the air pressure balance hole 10 are specifically set as stepped holes, that is, the lower end of the fourth groove 7 and both ends of the air pressure balance hole 10 are stepped. Due to the opening of the fifth groove 20, a part of the fifth groove 20 is opened on the third groove 6, and the bottom of the fifth groove 20 is located on the fourth groove 7. This makes the upper end of the fourth groove 7 also form a stepped shape under the influence of the fifth groove 20. Both ends of the first mounting member 16 and the second mounting member 17 are provided with snap-fit ​​members. This snap-fit ​​member can abut against the step of the stepped hole to complete the snap-fit. The lower end of the first mounting hole is also set as a stepped hole. The upper end of the straw 2 is sleeved in the first mounting hole, and the upper end of the straw 2 abuts against the stepped surface in the first mounting hole.

[0071] In this embodiment, the mounting base 14 is made of rubber, and an annular groove 30 is formed outside the opening of the first connecting hole 18 on the top of the mounting base 14, so that the opening of the first connecting hole 18 on the top of the mounting base 14 is separated from the top surface of the mounting base 14, so that the connecting end 8 can better fit with the opening of the first connecting hole 18 on the top of the mounting base 14, further ensuring the communication between the fluid channel 11 and the straw 2.

[0072] like Figure 3 , 4 As shown in Figures 5, 7 and 8: the surface of the connecting end 8 is set as an ellipsoid, and rotating connectors 21 are provided on both sides of the connecting end 8;

[0073] A rotating connection hole 22 is provided on the inner wall of the first groove 4 or the inner wall of the third groove 6;

[0074] The rotating connector 21 is fitted inside the rotating connection hole 22, and the rotating connector 21 can rotate within the rotating connection hole 22.

[0075] like Figure 7 As shown: The rotating connector 21 is provided with an inclined surface 23, which extends from the side of the rotating connector 21 to the end face of the rotating connector 21 away from the connecting end 8.

[0076] like Figure 1 As shown: The cup lid 1 is also provided with a handle 24, which is rotatably connected to the cup lid 1.

[0077] In this embodiment, two connectors are provided on both sides of the cup lid 1, and two holes are provided at both ends of the handle 24. The holes on the handle 24 are fitted onto the two connectors, and the two can rotate relative to each other, thereby completing the rotational connection between the cup lid 1 and the handle 24.

[0078] like Figure 8 As shown: the radial dimension of the cross-section of the fluid channel 11 located at the connecting end 8 is smaller than the radial dimension of the cross-section of the fluid channel 11 located at the free end 9.

[0079] In this embodiment, the fluid channel 11 has a certain length, and the connecting end 8 in the figure also has a certain volume. Therefore, specifically, the radial dimension of the cross-section of the part of the fluid channel 11 located inside the connector is smaller than the radial dimension of the cross-section of the fluid channel 11 at other positions on the nozzle 3. To better distinguish them, the part with the smaller radial dimension is the first fluid channel 28, while the part with the larger radial dimension is the second fluid channel 29.

[0080] like Figure 2 , 5 As shown in Figure 6: The bottom of the cup lid 1 is provided with a first extension 25 and a second extension 26. The cross-section of the first extension 25 and the second extension 26 is annular. The second extension 26 is sleeved inside the first extension 25. The openings of the fourth groove 7 and the air pressure balance hole 10 at the bottom of the cup lid 1 are both provided in the inner circle of the second extension 26. There is a space 27 between the first extension 25 and the second extension 26 for accommodating the cup mouth.

[0081] like Figure 5 As shown: The inner wall of the first extension 25 is provided with an internal thread, and the cup lid 1 is connected to the cup by the threaded connection.

[0082] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
