Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, and in particular to a thermos cup with anti-accidental opening function. Background Technology

[0002] Insulated water bottles, widely used in modern life, effectively maintain beverage temperatures thanks to their vacuum insulation structure and sealing properties, meeting users' needs for all-day portability. However, traditional insulated water bottles reveal significant drawbacks in practical use: when users need to drink hot water, they must fully unscrew the lid to pour the liquid. At this point, it's difficult to precisely control the angle of the bottle's tilt and the water flow rate, easily causing a sudden spill of hot water and posing a scalding risk. While lid structures with improved dispensing methods, such as direct-drinking spouts, have emerged in recent years, technical bottlenecks remain in terms of ease of use and safety.

[0003] For example, the Chinese utility model patent CN221511532U, entitled "A Double-Lid Insulated Cup," uses a combination of a screw cap and a direct drinking spout, with the spout opening and closing via rotation. While this design allows for control of the water flow, it requires both hands to screw on the cap for each use, making it extremely inconvenient for single-handed use scenarios such as walking or driving. More importantly, the frequent rotation of the screw structure can easily lead to wear on the sealing ring, posing a risk of leakage after prolonged use.

[0004] For example, the Chinese utility model patent "A Double Drinking Cup Lid" with patent publication number CN222640237U uses a press-type locking mechanism to control the opening and closing of the flip lid, and achieves flow restriction through the water passage at the bottom of the drinking slot. Although it improves the opening efficiency, its single-point press unlocking mechanism lacks accidental touch protection: when the thermos cup is placed in a bag and is under pressure or when a child accidentally touches it, the flip lid may open unexpectedly, causing hot water leakage and leading to a safety accident.

[0005] Existing solutions either sacrifice ease of operation for safety or oversimplify the structure, leading to protective failures. Neither of these solutions meets users' comprehensive needs for efficient and safe drinking water. Therefore, there is an urgent need in the market for a thermos that can control the water flow rate, is easy to open, and prevents accidental opening. Utility Model Content

[0006] This invention addresses the problem that existing solutions either sacrifice ease of operation for safety or oversimplify the structure, leading to protective failure. The technical problem this invention aims to solve is to provide a thermos cup that can control the water flow rate, is easy to open, and prevents accidental opening.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a thermos cup with anti-accidental opening, including a cup body and a cup lid covering the cup body. The cup lid has a water outlet sleeve that communicates with the cup body and extends vertically out of the top surface of the cup lid. A flip cover that seals the water outlet of the water outlet sleeve is hinged to the cup lid through a hinge shaft. The flip cover is made of elastic material. The end of the flip cover away from its hinge shaft is provided with an installation port that penetrates its side wall and top wall. A locking cover that covers the installation port is rotatably connected to the installation port. An elastic protrusion is provided on the inner side wall of the locking cover. A limiting groove that matches the elastic protrusion is provided on the outer wall of the water outlet sleeve.

[0008] When the flip cover is closed, the elastic protrusion is inserted into the limiting groove under the elastic pre-tightening force of the flip cover to lock the flip cover.

[0009] When the flip cover is opened, a first operating force is applied to push the locking cover upwards and flip it over, while a second operating force is applied to press the top surface of the flip cover to cause local deformation, so that the elastic protrusion disengages from the limiting groove.

[0010] A further preferred embodiment of this utility model is: the locking cover is provided with connecting shafts on both sides, and the mounting port is provided with shaft holes on both sides. The locking cover is inserted into the shaft holes through the connecting shafts on both sides and can rotate around the shaft holes.

[0011] A further preferred embodiment of this utility model is: the top edge of the flip cover extends horizontally to form an outer edge, and the top surface of the locking cover has a toggle portion that extends horizontally and is flush with the outer edge.

[0012] A further preferred embodiment of this utility model is as follows: a first slot is provided on the side wall of the end of the flip cover away from the hinge axis, and a second slot is provided on the top wall of the end of the flip cover away from the hinge axis, wherein the first slot and the second slot are connected to form the mounting opening.

[0013] A further preferred embodiment of this utility model is as follows: the top wall of the flip cover is provided with an arc-shaped hole communicating with the second slot, the wall of the arc-shaped hole is provided with a first arc-shaped step, the side of the locking cover near the arc-shaped hole is an arc-shaped notch, the arc wall of the arc-shaped notch is provided with an upper second arc-shaped step, the arc-shaped hole and the arc-shaped notch together form a circular mounting hole, the first arc-shaped step and the second arc-shaped step together form an annular step, a silicone plug is provided in the circular mounting hole, the silicone plug is provided with an annular groove adapted to the annular step, the silicone plug is locked in the annular mounting hole through the annular groove, and the lower end of the silicone plug has a plug that extends into the water outlet sleeve to block the water outlet of the water outlet sleeve.

[0014] A further preferred embodiment of this utility model is that the arc length of the arc-shaped hole is greater than the arc length of the arc-shaped notch.

[0015] A further preferred embodiment of this utility model is that the flip cover is made of silicone.

[0016] A further preferred embodiment of this utility model is that the water outlet sleeve is located at the edge of the cup lid.

[0017] A further preferred embodiment of this utility model is: the cup lid is provided with a handle, and the two ends of the handle are fixed to the side walls of the cup lid.

[0018] A further preferred embodiment of this utility model is: the cup lid is threadedly connected to the cup body, and the cup body has a double-layer structure with a vacuum cavity between the inner and outer layers.

[0019] Compared with existing technologies, this utility model has the following advantages: Firstly, the water outlet sleeve allows for control of the water flow speed during pouring. Secondly, the flip-top is designed with an elastic material, and a locking cap is rotatably connected at the installation opening to close it. When the flip-top is closed, the elastic protrusion is embedded in the limiting groove under the elastic pre-tightening force of the flip-top, locking the flip-top and preventing accidental opening, thus avoiding beverage leakage. When opening the flip-top, a first operating force is applied to push the locking cap upwards, causing the elastic protrusion to disengage from the limiting groove. Simultaneously, a second operating force is applied to press the top surface of the flip-top, causing local deformation and further helping the elastic protrusion to disengage from the limiting groove. This dual-operating-force design increases the difficulty of accidental opening; it can only be unlocked when the user consciously operates, effectively preventing accidental opening of the flip-top due to accidental contact, improving the safety and reliability of the thermos. Furthermore, both the first and second operating forces can be applied with one hand, making opening the lid convenient. Attached Figure Description

[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0031] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0032] This embodiment mainly describes a thermos cup with anti-accidental opening features, as detailed below:

[0033] like Figures 1 to 8As shown, a thermos cup with anti-accidental opening features includes a cup body 1 and a lid 2 that fits onto the cup body 1. The lid 2 is connected to the cup body 1 by a threaded connection. Specifically, the outer wall of the cup body 1 has external threads, and the inner wall of the lid 2 has internal threads. The opening of the cup body 1 extends into the lid 2 and is threadedly connected to it. Alternatively, the inner wall of the cup body 1 has internal threads, and the outer wall of the lid 2 has external threads. The lower side of the lid 2 is inserted into the cup body 1 and threadedly connected to it. The lid 2 has a water outlet sleeve 3 that communicates with the cup body 1 and extends vertically out of the top surface of the lid 2, providing a channel for beverage flow. A hinged flap 4, which seals the water outlet of the water outlet sleeve 3, is hinged to the lid 2 via a hinge shaft 5. The hinged flap 4 is made of an elastic material and has a certain elastic deformation capability. The end of the flip cover 4 away from its hinge axis 5 is provided with an installation port 41 that penetrates its side wall and top wall. A locking cover 6 is rotatably connected to the installation port 41 to close the installation port 41. An elastic protrusion 61 is provided on the inner side wall of the locking cover 6, and a limiting groove 31 that matches the elastic protrusion 61 is provided on the outer wall of the water outlet sleeve 3.

[0034] When the flip-top 4 is closed, the elastic protrusion 61, under the elastic pre-tightening force of the flip-top 4, embeds itself into the limiting groove 31, locking the flip-top 4 and preventing accidental opening, thus avoiding beverage leakage. When the flip-top 4 is opened, a first operating force is applied to push the locking cover 6 upwards to flip it over, while a second operating force is applied to press the top surface of the flip-top 4 to cause local deformation, causing the elastic protrusion 61 to disengage from the limiting groove 31, thereby unlocking and opening the flip-top 4. This structural design ensures the sealing of the thermos during normal use and effectively prevents accidental opening through a dual-operating-force unlocking mechanism, improving the safety and reliability of the thermos.

[0035] Specifically, the locking cover 6 has connecting shafts 65 on both sides, and shaft holes 413 are provided on both sides of the mounting opening 41. The locking cover 6 is inserted into the shaft holes 413 through the connecting shafts 65 on both sides and can rotate around the shaft holes 413. This structure allows the locking cover 6 to be stably installed at the mounting opening 41 of the flip cover 4 and to rotate flexibly around the shaft holes 413, thereby realizing the locking and unlocking operations of the elastic protrusion 61 and the limiting groove 31. The matching structure of the connecting shaft 65 and the shaft hole 413 is simple and reliable, easy to process, manufacture and install, while ensuring the movement accuracy and stability of the locking cover 6. In order to prevent the locking cover 6 from easily falling off when subjected to external force, the distance between the outer ends of the two connecting shafts 65 is designed to be greater than the width of the mounting opening 41, so that the locking cover 6 can be firmly fixed in the mounting opening 41 after installation, thereby improving the stability of the locking cover 6.

[0036] like Figure 6 As shown, the top edge of the flip cover 4 extends horizontally to form an outer edge 44, as... Figure 4 and Figure 7As shown, the top surface of the locking cover 6 has a horizontally extending actuating portion 64, which is flush with the outer edge 44. The design of the actuating portion 64 makes it easy for the user to apply an initial operating force to push the locking cover 6 upward, thereby unlocking it. The structure design, where the outer edge 44 is flush with the actuating portion 64, makes the operation more comfortable and convenient for the user, while also enhancing the overall aesthetics of the thermos.

[0037] like Figure 5 and Figure 6 As shown, the side wall of the flip cover 4 away from the hinge axis 5 has a first slot 411 penetrating the side wall, and the top wall of the flip cover 4 away from the hinge axis 5 has a second slot 412 penetrating the top wall. The first slot 411 and the second slot 412 communicate to form the mounting opening 41. This slot structure design allows the shape and size of the mounting opening 41 to meet the installation and rotation requirements of the locking cover 6, and also facilitates manufacturing. The connection between the first slot 411 and the second slot 412 forms a stable installation space, providing a reliable structural foundation for the installation of the locking cover 6, and further enhancing the stability of the anti-accidental opening function of the thermos cup.

[0038] like Figure 6 As shown, the top wall of the flip cover 4 has an arc-shaped hole 42 communicating with the second slot 412, and the wall of the arc-shaped hole 42 has a first arc-shaped step 43. Figure 7 As shown, the locking cover 6 has an arc-shaped notch 62 on the side near the arc-shaped hole 42, and a second arc-shaped step 63 is provided on the arc-shaped wall of the arc-shaped notch 62. The arc-shaped hole 42 and the arc-shaped notch 62 together form a circular mounting hole, and the first arc-shaped step 43 and the second arc-shaped step 63 together form a ring-shaped step. A silicone plug 7 is provided inside the circular mounting hole, such as... Figure 8 As shown, the silicone plug 7 has an annular groove 71 that matches the annular step. The silicone plug 7 is secured in the circular mounting hole through the annular groove 71. The lower end of the silicone plug 7 has a plug 72 that extends into the water outlet sleeve 3 to block the water outlet of the water outlet sleeve 3. This structural design allows the silicone plug 7 to be stably installed in the circular mounting hole and reliably fixed through the cooperation of the annular groove 71 and the annular step. The plug 72 at the lower end of the silicone plug 7 extends into the water outlet sleeve 3 to block the water outlet of the water outlet sleeve 3, further enhancing the sealing performance of the thermos. In the unlocked state, when the flip cover 4 is opened, the silicone plug 7 can disengage from the water outlet sleeve 3 with the movement of the flip cover 4, thereby allowing the beverage to flow out. This design not only improves the sealing performance of the thermos but also makes the control of the water outlet more flexible and reliable, further enhancing the performance of the thermos.

[0039] Specifically, the arc length of the arc-shaped hole 42 is greater than the arc length of the arc-shaped notch 62. This design allows the silicone plug 7 to be stably installed on the flip cover 4. The circular mounting hole formed by the arc-shaped hole 42 and the arc-shaped notch 62 has sufficient space to accommodate the silicone plug 7 and ensure its stability during installation and use. At the same time, the larger arc length of the arc-shaped hole 42 also facilitates the installation and removal of the silicone plug 7, making it easier for users to clean and maintain the thermos.

[0040] Specifically, the flip cover 4 is made of silicone. Silicone has good elasticity, flexibility, and high-temperature resistance, which meets the elastic deformation requirements of the flip cover 4 during use, while ensuring the normal use of the thermos in high-temperature environments. The silicone flip cover 4 is comfortable to the touch, easy to clean, and has a certain degree of anti-slip performance, further enhancing the user experience and safety of the thermos.

[0041] like Figure 1 As shown, the water outlet sleeve 3 is located on the edge of the lid 2. This design makes the position of the water outlet sleeve 3 more reasonable, allowing users to directly place their lips close to the water outlet sleeve 3 when drinking, thus improving the convenience of drinking. At the same time, the location of the water outlet sleeve 3 on the edge of the lid 2 also facilitates processing, manufacturing, and installation, further reducing the production cost of the thermos.

[0042] Specifically, the lid 2 is equipped with a handle 8, the two ends of which are fixed to the side walls of the lid 2. The handle 8 design makes it convenient for users to carry the thermos, especially when traveling or exercising. Users can easily hang the thermos on their backpack or wrist, improving its portability. The handle 8, with its two ends fixed to the side walls of the lid 2, has a simple and sturdy structure that can withstand a certain amount of pulling force, ensuring the stability of the thermos during transport.

[0043] like Figure 3 As shown, the cup body 1 has a double-layer structure, with a vacuum cavity 9 between the inner and outer layers. The double-layer structure of the cup body 1 and the vacuum cavity 9 effectively insulate against heat, maintaining the temperature of the beverage and extending the insulation time, thus meeting users' requirements for heat preservation performance. This structural design not only improves the heat preservation effect of the thermos but also ensures its overall stability and reliability.

[0044] The water outlet sleeve 3 of this utility model thermos cup enables control of the water flow speed when pouring water. The flip cover 4 is designed with elastic material and a locking cover 6. The flip cover 4 has multiple functions such as preventing accidental opening and convenient opening, which meets the comprehensive needs of users for efficient and safe drinking water and has good market application prospects.
