Description

Technical Field

[0001] This invention relates to the technical field of cup bodies, and more particularly to a double-layered press-to-unlock safety cup lid and a thermos cup. Background Technology

[0002] Insulated cups, with their excellent heat retention properties, have become an indispensable beverage container in people's daily lives. The lid, as a crucial component of the insulated cup, directly impacts the user experience with its sealing performance and ease of opening and closing. Traditional insulated cups, for ease of use, feature lids that can be unlocked by pressing a button, allowing the lid to automatically flip open under the action of a torsion spring. However, this type of lid is prone to opening due to accidental bumps or presses of the button, leading to problems such as leaks and burns.

[0003] Therefore, existing technology provides a cup lid with a safety mechanism that locks the lid's button, allowing the lid to be opened only after unlocking. However, the safety mechanism of such cup lids typically uses a separate toggle switch design. Users must first operate the toggle switch to unlock the lid before pressing the button to open it. This results in users having to find the toggle switch, making the operation cumbersome and inconvenient. Summary of the Invention

[0004] To address the problems mentioned above, this invention provides a double-layer press-to-unlock cup lid and a thermos cup, which not only achieves stable locking of the cup lid, but also has a simple unlocking operation logic that fits daily usage habits and greatly improves ease of use.

[0005] The solution adopted by this invention to solve its technical problem is: a double-layer press-to-unlock safety cup lid, including a bottom cover and a top cover with a hinged cover disposed on the top of the bottom cover, wherein the bottom cover has a locking mechanism at the opposite edge of the hinged position that engages with the top cover, and the locking mechanism includes: A snap button is used to fasten the top cover. The bottom cover has a radially extending movable channel that penetrates the top surface of the bottom cover. The snap button is slidably embedded in the movable channel and its top is fastened to the top cover. An unlocking channel is provided through the center of the snap button along the length of the movable channel. The unlock button is embedded within the unlock channel; and An elastic blocking member is embedded at the end of the movable channel. The elastic blocking member has elastic arms on both sides that abut against the buckle button. The end of the unlock button is inserted between the two elastic arms and abuts against the inner wall of the elastic arm. In the initial state, the elastic blocking member blocks the snap button, restricting the snap button from moving along the active channel to release it from the top cover; When the unlock button is pressed, the unlock button causes the elastic arm to deform, releasing the elastic blocking member from obstructing the latch button, allowing the latch button to move along the movable channel and thus release the latch from the top cover.

[0006] Furthermore, the end of the elastic arm is provided with a blocking part, and the side of the buckle button is provided with a blocking block corresponding to the elastic arm. The ends of the blocking block and the blocking part are both vertical planes and abut against each other in the initial state.

[0007] Furthermore, the unlock button has triggering blocks on both sides extending from its end toward its front end. The width of the triggering blocks gradually increases with its extension direction and pushes the elastic arm to deform and open when the unlock button is pressed, thus misaligning it with the contact position of the latch button.

[0008] Furthermore, a guide portion is provided at the end of the elastic arm corresponding to the position of the triggering inclined block. The guide portion is folded towards the outer wall of the elastic arm to form an inclined surface that facilitates the sliding of the triggering inclined block along the inner wall of the elastic arm.

[0009] Furthermore, the active channel is provided with a reset spring for pushing the unlock button to reset. One end of the reset spring abuts against the elastic blocking member, and the other end of the reset spring abuts against the unlock button.

[0010] Furthermore, a positioning block is provided on the end wall of the active channel, and a positioning hole is provided at the center of the elastic blocking member. When the elastic blocking member is installed, the positioning block passes through the positioning hole.

[0011] Furthermore, the end of the active channel is provided with a limiting chamber, and the ends of both sides of the buckle button are provided with limiting parts that move within the limiting chamber; the end of the unlocking channel is provided with a limiting protrusion extending toward the center of the unlocking channel, and the end of the unlocking button is provided with a limiting block at the position corresponding to the limiting protrusion.

[0012] Furthermore, the surface height of the unlock button is lower than the surface height of the latch button.

[0013] Furthermore, the top of the buckle button is provided with a locking tongue that extends through the movable channel and is exposed on the top surface of the bottom cover. The inner wall of the top cover on the other side opposite to the hinge position is provided with a locking opening. When the top cover is fastened, the locking tongue is embedded in the locking opening.

[0014] The present invention also provides a thermos cup, including a cup body, wherein the top of the cup body is provided with a safety cup lid as described in any one of claims 1-9, and the safety cup lid is threadedly connected to the cup body.

[0015] In summary, the beneficial effects of the present invention are as follows: 1. This invention provides an elastic blocking element within the active channel for unlocking the snap button, with the elastic arms on both sides of the elastic blocking element abutting against the side of the snap button to block its movement. This effectively prevents the snap button from being accidentally pressed, thus preventing the top cover from opening unexpectedly. This achieves double locking of the top cover, thereby preventing risks such as water leakage and burns, and significantly improving safety.

[0016] 2. This invention sets an unlocking channel at the center of the latch button and installs an unlocking button that abuts against the inner wall of the elastic arm in the unlocking channel. When the unlocking button is triggered, it can push the elastic arm to deform, thereby releasing the obstruction of the latch button and thus unlocking. The operation logic is simple, and unlocking only requires double pressing in the same position, which fits daily usage habits and greatly improves the convenience of use.

Unless otherwise stated, "a plurality of" means two or more.

[0022] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of these terms in this invention based on the specific circumstances.

[0023] like Figures 1 to 4 As shown, this embodiment discloses a double-layer press-to-unlock safety cup lid. The double-layer press-to-unlock structure achieves stable locking of the top cover 2, preventing accidental opening that could lead to leakage or scalding. It also simplifies operation, improves ease of use, and balances insulation performance and safety. The safety cup lid of this embodiment includes a bottom cover 1, a top cover 2, and a locking mechanism 3. The bottom cover 1 is threadedly connected to the body 4 of the insulated cup, and has a hinge at its top edge. One edge of the top cover 2 is hinged to the hinge via a hinge shaft, allowing the top cover 2 to rotate around the hinge shaft, thus enabling the bottom cover 1 to be closed and opened. The locking mechanism 3 is located on the other side of the bottom cover 1 opposite the hinge, ensuring a stable connection between the top cover 2 and the bottom cover 1. This allows the top cover 2 to close and surround the spout on the bottom cover 1 after closing, preventing dust from entering or beverage leakage, ensuring cleanliness and sealing performance.

[0024] like Figures 2 to 4As shown, in order to achieve stable unlocking and latching of the top cover 2, the bottom cover 1 of this embodiment has a movable channel 11 extending radially and penetrating the top surface of the bottom cover 1 at the edge where it latches with the top cover 2. The latching mechanism 3 is located in the movable channel 11, so that when the top cover 2 is latched, it can latch with the latching mechanism 3 in the movable channel 11 to achieve stable closing of the top cover 2; when the latching mechanism 3 is pressed to trigger it, the latching mechanism 3 can be disengaged from the latching position, thereby realizing the opening of the top cover 2. Specifically, the latching mechanism 3 of this embodiment includes a latch button 31, wherein the latch button 31 is movably disposed in the movable channel 11, and the top is integrally formed with an upwardly protruding latch 35, which protrudes out of the movable channel 11 and is exposed on the top surface of the bottom cover 1; correspondingly, the inner wall of the top cover 2 on the other side opposite the hinge position is provided with a lock opening 21 adapted to the latch 35. When the top cover 2 is closed, the locking tongue 35 can be embedded in the locking opening 21 to achieve the locking of the top cover 2 and the bottom cover 1; when the buckle button 31 is pressed, the buckle button 31 slides along the moving channel 11, thereby causing the locking tongue 35 on its top to disengage from the locking opening 21 on the inner wall of the top cover 2, and then engage with the top cover 2 to achieve the opening of the top cover 2, which is convenient to use.

[0025] In order to prevent the top cover 2 from being accidentally opened due to accidental touch or collision of the latch button 31, the latching mechanism 3 of this embodiment is also provided with an elastic blocking member 33. The elastic blocking member 33 of this embodiment is embedded at the end of the movable channel 11, and elastic arms 331 extending along the length direction of the movable channel 11 are symmetrically provided on both sides. After the latch button 31 is installed into the movable channel 11, the end of the elastic arm 331 can abut against the side of the latch button 31, thereby blocking the movement of the latch button 31 in the movable channel 11, thus preventing the top cover 2 from being opened due to accidental touch or collision of the latch button 31.

[0026] Furthermore, the locking mechanism 3 of this embodiment also includes an unlocking button 32 for unlocking. When the unlocking button 32 is triggered, it can release the obstruction of the snap button 31 by the elastic blocking member 33, thereby allowing the snap button 31 to move along the movable channel 11 and release its engagement with the top cover 2. Specifically, the snap button 31 of this embodiment has an unlocking channel 311 extending along the length direction of the movable channel 11 at its center. The unlocking button 32 is movably embedded in the unlocking channel 311 and can slide along the unlocking channel 311, so that the unlocking button 32 can be pressed independently relative to the snap button 31. The end of the unlocking button 32 is inserted between two elastic arms 331, and the two sides of the unlocking button 32 abut against the inner walls of the two elastic arms 331 respectively. Thus, when the unlocking button 32 is triggered, it can push the two elastic arms 331 to expand outward, thereby causing the side of the snap button 31 to be misaligned with the end of the elastic arms 331, releasing the obstruction of the snap button 31, so that the snap button 31 can move along the movable channel 11 to open the top cover 2.

[0027] like Figure 2 and Figure 3 As shown, in the initial state, the elastic arm 331 is in a naturally straight state, and its end forms a rigid abutment with the side of the latch button 31, blocking the sliding of the latch button 31 and restricting the movement of the latch button 31 along the movable channel 11, thus preventing it from being released from the latch with the top cover 2 and locking the top cover 2. When it is necessary to open the cup lid, first press the unlock button 32. The unlock button 32 moves along the unlock channel 311 to the end of the movable channel 11 and drives the elastic arm 331 to deform and open to both sides, releasing the elastic blocking member 33 from blocking the latch button 31. At this time, the latch button 31 can be pushed to slide along the movable channel 11, thereby releasing the latch with the top cover 2 and opening the top cover 2.

[0028] Specifically, such as Figures 3 to 4 As shown, in this embodiment, the end of the elastic arm 331 is integrally formed with a blocking portion 332 extending toward the snap button 31, and the end of the blocking portion 332 is a vertical plane. Correspondingly, the two side walls of the snap button 31 are integrally formed with blocking blocks 312 corresponding to the position of the elastic arm 331, and the ends of the blocking blocks 312 are also vertical planes. In the initial state, the vertical planes of the blocking portion 332 and the vertical planes of the blocking blocks 312 abut against each other to form a surface contact blocking, thereby preventing the snap button 31 from sliding in the active channel 11. This can prevent the snap button 31 from being displaced due to vibration or slight touch, which would cause the top cover 2 to open, and the blocking stability is strong.

[0029] In order to efficiently push the elastic arm 331 to deform when the unlock button 32 is pressed, the unlock button 32 in this embodiment is provided with triggering wedges 321 extending from the end of the unlock button 32 toward the front end of the unlock button 32 on both sides. The width of the triggering wedges 321 gradually increases along the extension direction (i.e. from the end of the active channel 11 to the opening end of the active channel 11), forming a wedge structure. When the unlock button 32 is pressed, the triggering wedges 321 move toward the elastic arm 331 with the unlock button 32. The inclined side of the triggering wedges slide against the inner wall of the elastic arm 331. By using the guiding effect of the wedge structure, the axial force of the press is converted into a radial force that pushes the elastic arm 331 to open to both sides. This causes the elastic arm 331 to deform and open quickly and form a misalignment with the blocking block 312 of the latching button 31, thereby smoothly releasing the obstruction and unlocking the latching button 31.

[0030] Furthermore, in this embodiment, a guide portion 333 is provided at the end of the elastic arm 331 corresponding to the position of the triggering inclined block 321. The guide portion 333 is folded towards the outer wall of the elastic arm 331 to form a smooth inclined surface. This inclined surface is adapted to the side of the triggering inclined block 321, which can reduce the friction when the triggering inclined block 321 slides, making the pressing operation of the unlock button 32 smoother, while avoiding wear on the inner wall of the elastic arm 331 due to long-term friction, thus extending its service life.

[0031] like Figure 2 and Figure 4 As shown, the active channel 11 of this embodiment is also provided with a reset spring 34. One end of the reset spring 34 abuts against the end face of the elastic blocking member 33, and the other end abuts against the end face of the unlock button 32. When the unlock button 32 is pressed, the reset spring 34 can be compressed and store elastic potential energy. When the unlock button 32 is released, the reset spring 34 releases the elastic potential energy and pushes the unlock button 32 to automatically reset to the initial position. At this time, the elastic arm 331 returns to its natural straight state under its own elastic action and squeezes and pushes the latch button 31 back along the active channel 11, so that the end of the elastic arm 331 abuts against the blocking block 312 of the latch button 31 again, restoring the blocking of the latch button 31. No manual reset is required, making it convenient to use.

[0032] To achieve precise positioning and installation of the elastic blocking component 33, a positioning block 12 is integrally formed on the wall surface at the end of the movable channel 11 in this embodiment. A positioning hole 334 adapted to the positioning block 12 is provided at the center of the elastic blocking component 33. When the elastic blocking component 33 is installed, the positioning block 12 passes through the positioning hole 334 to form a positioning fit, which can prevent the elastic blocking component 33 from shifting or rotating within the movable channel 11, ensuring that the elastic arm 331 and the blocking block 312 of the latch button 31 always maintain precise alignment, thereby improving the stability of the blocking and unlocking functions.

[0033] like Figure 3 and Figure 4 As shown, the active channel 11 of this embodiment is provided with a limiting chamber 13 that extends to both sides at the end. The two ends of the snap button 31 are integrally formed with limiting parts 313 that are adapted to the limiting chamber 13. The limiting parts 313 move within the limiting chamber 13. The length of the limiting chamber 13 is aligned with that of the movable channel 11, and its width is greater than that of the movable channel 11. This allows limiting surfaces to be formed between the two sides of the limiting chamber 13 and the two side walls of the movable channel 11, which can limit the sliding stroke of the latch button 31, preventing excessive sliding of the latch button 31 and damage to the latching structure with the top cover 2, and preventing the latch button 31 from falling out of the movable channel 11. In addition, the end of the unlocking channel 311 is provided with a limiting protrusion 314 extending toward the center of the unlocking channel 311. The end of the unlocking button 32 is provided with a limiting block 322 at the position corresponding to the limiting protrusion 314. The limiting protrusion 314 and the limiting block 322 form a limiting engagement, which can limit the pressing stroke of the unlocking button 32, preventing excessive pressing of the unlocking button 32 and causing the triggering block 321 to over-compress the elastic arm 331, resulting in permanent deformation of the elastic arm 331, and ensuring the service life of the elastic blocking component 33.

[0034] like Figure 1As shown, in order to further reduce the probability of accidental touch, the surface height of the unlock button 32 in this embodiment is lower than the surface height of the latch button 31, forming a double-layer button structure with different heights. This allows users to quickly identify the operation sequence during use, and the lower unlock button 32 is less likely to be accidentally touched, thereby effectively reducing the probability of accidental touch of the unlock button 32 and further improving the safety of use.

[0035] This embodiment also provides a thermos cup, including a cup body 4. The top of the cup body 4 is provided with the aforementioned safety cup lid. The inner wall of the bottom cover 1 of the safety cup lid is provided with internal threads, and the outer wall of the top of the cup body 4 is provided with external threads. The safety cup lid and the cup body 4 are connected by threads, which is firm and has good sealing performance, effectively ensuring the heat preservation effect of the thermos cup. At the same time, with the double locking structure of the safety cup lid, it prevents water leakage and scalding caused by accidental contact when carrying or placing the thermos cup, thus improving the safety and practicality of the thermos cup.

[0036] In summary, this embodiment achieves anti-accidental locking through the abutting cooperation between the elastic blocking member 33 and the snap button 31, and achieves convenient unlocking through the linkage between the unlock button 32 and the elastic arm 331. The operation logic is simple, and the cup lid can be opened by simply pressing the double layer in the same position. The method of use is convenient and fits daily usage habits, effectively solving the problems of easy accidental touch and cumbersome operation of traditional cup lids.

[0037] The embodiments described above are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and modifications made by those skilled in the art based on the invention shall fall within the scope of protection of the present invention.
