Description

Technical Field

[0001] This utility model belongs to the field of thermos cup technology, specifically relating to a thermos cup with an easy-to-open lid. Background Technology

[0002] As a commonly used liquid container, the core structure of a thermos usually includes an inner liner, an outer shell, and a vacuum insulation layer between the inner liner and the outer shell. The inner liner is often made of ceramic or stainless steel. The vacuum insulation layer can effectively block the heat exchange between the liquid inside and the external environment, slow down the heat dissipation of the liquid, and thus achieve the effect of keeping the liquid warm. It is widely used in daily life, office and outdoor scenarios.

[0003] In the overall structure of a thermos, the lid is a key component that ensures ease of use and airtightness. Currently, the mainstream lid structures on the market are mainly divided into two types: rotary lid and push-button lid. Among them, the rotary lid is opened and closed by rotating the inner plug. In actual use, changes in the temperature of the liquid inside the cup cavity can easily cause pressure fluctuations (such as the decrease in pressure inside the cup after hot water cools down), resulting in negative pressure adsorption between the inner plug and the cup mouth. Users need to apply a lot of force to open it, which is especially inconvenient for the elderly, children and other people with weak hand strength, affecting the user experience.

[0004] Button-operated thermos cups, which open by pressing the button in the middle of the lid, are popular due to their ease of use. However, existing thermos cups of this type have significant drawbacks in carrying and use: the button is often directly exposed on the outside of the lid and lacks an effective anti-accidental touch locking mechanism. When the thermos cup is placed in a backpack or handbag, or during daily storage or handling, the button is easily triggered by external impacts or accidental touches, causing the lid to open accidentally. This not only causes liquid leakage, wetting clothes and backpack items, but also poses a serious safety hazard. If the cup contains hot water, the leaked hot water can easily scald the body, threatening the user's personal safety. This fails to meet the user's requirements for the safety and reliability of thermos cups. In summary, rotary lids cannot meet the user's need for "convenient opening," and while existing button-operated lids achieve "easy opening," they pose safety hazards due to the lack of anti-accidental touch design. To solve the above problems, this application proposes a thermos cup with an easy-to-open lid. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a thermos cup with an easy-to-open lid, featuring easy-to-open pop-up lid and effective prevention of accidental contact.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermos cup with an easy-to-open lid, comprising a thermos cup body, the open end of which is connected to a lid body by a thread, the lid body having a drinking spout, and the lid body being hinged to a spring-loaded lid body via a pivot.

[0007] A button frame is provided on one side of the cup lid body, and connecting plates are hinged to both sides of the button frame via a pivot.

[0008] An anti-accidental touch component is disposed on the connecting plate and includes a baffle that can move relative to the button frame to cover the operating area of ​​the button frame.

[0009] Preferably, the anti-accidental touch component includes a fixing plate disposed on both sides of the connecting plate, and a connecting rod is symmetrically provided on one side of the two connecting plates, with both ends of the connecting rod being fixedly connected to the connecting plate and the fixing plate respectively;

[0010] Two sets of connecting rods are slidably fitted with baffles, and the outer wall of the connecting rods is fitted with a return spring, the two ends of the return spring abutting against the baffle and the fixing plate respectively.

[0011] Preferably, one side of the button frame is provided with two pairs of limiting plates for the baffle to be embedded in.

[0012] Preferably, each of the two fixed plates is rotatably connected to a roller on one side, and the outer wall of the roller abuts against the inner wall of the baffle.

[0013] Preferably, both sides of the baffle are provided with pushing blocks, and the pushing blocks are provided with anti-slip textures.

[0014] Preferably, a closure element is fixed inside the inner side of the spring cover body.

[0015] Preferably, the closure element is a conical sealing block and is made of silicone material.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, by setting up an anti-accidental touch component, the baffle automatically resets under the action of the return spring, and in conjunction with the limiting plate, the baffle is precisely limited in the horizontal direction. This effectively avoids the problem of accidental button triggering caused by external collisions or accidental touches during the carrying or placement of the thermos cup, thereby preventing liquid leakage and scalding risks caused by accidental opening of the cup lid. At the same time, through the design of the pushing block and anti-slip texture, users can easily push the baffle to expose and cover the button operation area, ensuring both the convenience of opening and the safety of use.

[0018] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] Please see Figures 1-5 The present invention provides the following technical solution: a thermos cup with an easy-to-open lid, comprising a thermos cup body 1, a lid body 2 connected to the open end of the thermos cup body 1 by a thread, a drinking spout 3 on the lid body 2, and a spring lid body 4 hinged to the lid body 2 by a pivot.

[0029] A button frame 6 is provided on one side of the cup lid body 2, and connecting plates 7 are hinged to both sides of the button frame 6 via pivots.

[0030] An anti-accidental touch component 100 is provided on the connecting plate 7 and includes a baffle 103 that can move relative to the button frame 6 to cover the operating area of ​​the button frame 6. The anti-accidental touch component 100 includes a fixing plate 102 provided on both sides of the connecting plate 7. A connecting rod 101 is symmetrically provided on one side of the two connecting plates 7, and the two ends of the connecting rod 101 are fixedly connected to the connecting plate 7 and the fixing plate 102 respectively.

[0031] Two sets of connecting rods 101 are slidably fitted with baffles 103. The outer wall of the connecting rods 101 is fitted with a return spring 104. The two ends of the return spring 104 abut against the baffle 103 and the fixing plate 102 respectively. Both sides of the baffle 103 are provided with push blocks 105, and the push blocks 105 are provided with anti-slip textures 106. In use, in the initial state, the baffle 103 is in the closed position under the elastic force of the return spring 104, completely covering the operating area of ​​the button frame 6, forming an effective shield, which can prevent the button from being accidentally triggered due to accidental touch or collision during carrying or placement, and avoid the cup lid from being accidentally opened.

[0032] When it is necessary to open the pop-up lid body 4, the user only needs to push the push blocks 105 on both sides of the baffle 103 with his finger to the outside. The anti-slip texture 106 increases the friction, causing the baffle 103 to slide away from the button frame 6 along the connecting rod 101. At this time, the reset spring 104 is compressed, and the operating area of ​​the button frame 6 is exposed. Then, rotate the baffle 103 downward so that the baffle 103 moves to the bottom of the button frame 6 and fits. At this time, the button frame 6 is fully exposed, and the user can directly press the button to open the pop-up lid body 4. After the pop-up lid body 4 is opened by rotating around the hinge axis, the drinking spout 3 is exposed for easy drinking.

[0033] After drinking, the operation can be reversed to close the device: first push the baffle 103 away from the button frame 6 (to release the bottom contact state), then flip the baffle 103 upwards to return it to a position parallel to the button frame 6. Then release the push block 105. Under the elastic restoring force of the return spring 104, the baffle 103 slides along the connecting rod 101 towards the button frame 6, and finally returns to the initial closed position, covering the operating area of ​​the button frame 6 again, forming a stable anti-accidental touch protection. This achieves the synergistic optimization of "easy to open" and "safe anti-accidental touch".

[0034] Preferably, by Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, two pairs of limiting plates 8 are provided on one side of the button frame 6 for the baffle 103 to be embedded in. The two pairs of limiting plates 8 are respectively located at corresponding positions on both sides of the button frame 6, and their height is adapted to the thickness of the baffle 103. When the baffle 103 is in the closed state, it can be accurately embedded in the groove formed between the two pairs of limiting plates 8. The side wall of the limiting plate 8 limits the baffle 103 in the horizontal direction, preventing the baffle 103 from shifting or shaking under the elastic force of the return spring 104. This ensures that the baffle 103 can accurately cover the operating area of ​​the button frame 6, improves the stability and reliability of the anti-accidental touch component 100, and further enhances the safety and convenience of opening the thermos cup.

[0035] Preferably, by Figure 3 and Figure 4 As shown, in this embodiment, rollers 107 are rotatably connected to one side of each of the two fixed plates 102. The outer wall of the rollers 107 abuts against the inner wall of the baffle 103. When the baffle 103 slides on the connecting rod 101, the rollers 107 will rotate accordingly, changing the original sliding friction into rolling friction. This greatly reduces the friction force experienced by the baffle 103 during the sliding process, making it easier and less strenuous for the user to push or pull the baffle 103, and the operation is smoother, effectively improving the user's experience when using the thermos.

[0036] Preferably, by Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a closing member 5 is fixed inside the spring cap body 4. The closing member 5 is a conical sealing block made of silicone material. When the spring cap body 4 rotates around the hinge axis to the closed state, the conical sealing block will be tightly embedded in the corresponding sealing groove on the cup cap body 2. The silicone material has good flexibility and elasticity, and can undergo a certain degree of deformation to fill the tiny gap between the sealing groove and the sealing block, forming a reliable sealing effect and effectively preventing liquid leakage in the cup. At the same time, the silicone material also has the characteristics of high temperature resistance and corrosion resistance, which can adapt to the liquid holding needs of different temperatures and properties, further ensuring the performance and safety of the thermos cup.

[0037] Components not described in detail in this article are existing technologies.

[0038] The working principle and usage process of this utility model: When in use, the thermos cup body 1 serves as the main liquid storage body. The initial seal is achieved through the threaded connection between its open end and the cup lid body 2, ensuring that the overall structure is stable and easy to disassemble and clean. In the initial state, the baffle 103 in the anti-accidental touch component 100 is precisely embedded between the two pairs of limiting plates 8 on one side of the button frame 6 under the pre-tightening force of the return spring 104, completely covering the operating area of ​​the button frame 6. The limiting plates 8 prevent the baffle 103 from shifting by limiting the side wall. At the same time, the return spring 104 continuously provides elastic force in the direction of the button frame 6. The double protection can effectively isolate accidental external contact and prevent accidental button triggering that causes the pop-up lid body 4 to open accidentally, avoiding the risk of liquid leakage or burns.

[0039] When a user needs to drink the liquid in the cup, the operation process is divided into three steps: First, the user applies a push force to the anti-slip texture 106 on the surface of the push block 105 away from the button frame 6, causing the baffle 103 to slide along the connecting rod 101. During this process, the roller 107 on one side of the fixed plate 102 rolls into contact with the inner wall of the baffle 103, converting sliding friction into rolling friction, which significantly reduces the resistance to movement. The user does not need to apply too much force to push the baffle 103. At the same time, the return spring 104 is compressed and stores elastic potential energy.

[0040] The second step is to slide the baffle 103 until it is completely separated from the operating area of ​​the button frame 6, and then rotate the baffle 103 downward so that it fits the bottom of the button frame 6. At this time, the connecting plate 7 rotates synchronously with the rotation of the baffle 103, and the button frame 6 is fully exposed.

[0041] The third step is to press the button located inside the button frame 6. This button, through the built-in existing spring-loaded opening mechanism, directly acts on the locking mechanism inside the spring-loaded lid body 4, thereby releasing the locking state between the spring-loaded lid body 4 and the cup lid body 2. Subsequently, under the elastic force of its own spring (conventional design), the spring-loaded lid body 4 flips upward around the pivot hinged to the cup lid body 2, exposing the drinking spout 3 for easy drinking;

[0042] After drinking, first close the spring cap body 4, rotating it downwards around the hinge axis until it fits snugly against the cup lid body 2. At this time, the conical closing piece 5 fixed inside the spring cap body 4 will precisely embed into the corresponding sealing groove on the cup lid body 2. The silicone sealing block fills the gap between the sealing groove and the sealing block through its own deformation, forming a reliable sealing structure and effectively preventing liquid leakage from the cup. Then, the user once again uses their fingers to press and push the anti-slip texture 106 on the surface of the push block 105, applying a pulling force outwards, causing the baffle 103 to move along the connecting rod 101. Slide and compress the reset spring 104; when the baffle 103 slides between the two pairs of limiting plates 8 on one side of the button frame 6, the push block 105 is released, and the baffle 103, under the elastic restoring force of the reset spring 104, is precisely embedded in the groove formed by the limiting plates 8, completely covering the operating area of ​​the button frame 6, and restoring the initial anti-accidental touch state; this design, through the dual action of mechanical limiting and spring reset, ensures that the baffle 103 can stably cover the button area in the closed state, effectively avoiding the risk of accidental opening due to accidental touch;

[0043] Throughout the entire process, all components work together to achieve convenient opening of the pop-up lid body 4 through a simple two-step operation of "push-rotate", meeting the core requirement of "easy opening". At the same time, the limit of the anti-accidental touch component 100, the spring reset and the reliable sealing of the seal solve the problems of easy accidental touch and easy leakage of existing button-type thermos cups. It takes into account both the convenience of operation and the safety of use, and meets the diverse needs of daily use scenarios.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
