Description

Technical Field

[0001] This utility model relates to the field of cup technology, and in particular to a threadless quick-opening cup lid and cup. Background Technology

[0002] Cups are essential drinking tools in people's daily lives. To prevent leakage and for easy portability, most cups have a sealable lid. However, the lid typically attaches to the cup using a screw thread, which requires holding the cup with one hand and the lid with the other to open or close, making it inconvenient. While screwless lids have emerged, such as the new screwless thermos disclosed in Chinese utility model patent CN220713594U, which only requires pressing down on a trigger to open the lid... The trigger part of the device moves downward until it contacts the inclined surface of the protrusion. Under the guidance of the inclined surface, the protrusion is peeled off from the snap-fit ​​edge. Then, under the action of the spring, the spring provides a downward elastic force relative to the trigger part to the lifting part, causing the seal to return to its initial state. At this time, the cup lid can be easily removed, and the lifting part can be lifted upward to seal the thermos cup. Although it is also operated by pressing and lifting, the lower end of the trigger part is provided with a through hole in the structure. During frequent operation, this will inevitably reduce the service life of the trigger part, which will lead to the scrapping of the whole and greatly increase the cost of use. Therefore, it cannot meet the use requirements. Utility Model Content

[0023] (III) The technical effects to be achieved

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] Firstly, the pull-lock assembly of this utility model includes a pull member that passes through the cover and the seal. The pull member is provided with a solid trigger that moves back and forth along the pull member and a horizontally moving slider. The inner side wall of the cover is provided with a locking part that cooperates with the slider. The downward movement of the solid trigger causes the slider to move horizontally to one side, and the locking part will disengage from the slider and abut against the lock, causing the seal to deform and return to its original shape. When the pull member is pulled up, the locking part will cause the slider to move horizontally to one side until the locking part is abutted and locked by the slider. Finally, the seal on the pull member is squeezed, expanded and deformed. This not only allows for unlocking by pressing and sealing by lifting, but also makes the internal structure more robust, greatly improving the internal structural strength, extending the service life and reducing cost.

[0026] Secondly, the solid trigger of this utility model includes a solid trigger body that can move up and down in the lifting member, a return member is provided between the solid trigger body and the lifting member, and a first inclined surface is provided on the solid trigger body. The sliding member includes a sliding block that can move back and forth horizontally in the lifting member, a reset member is provided between the sliding block and the lifting member, a sliding position is provided on one side of the sliding block for the solid trigger body to pass through, a second inclined surface that cooperates with the first inclined surface is provided on the sliding position, a protrusion that cooperates with the locking part is provided on the other side of the sliding block, a limiting hole is provided on the lifting member, the protrusion moves back and forth in the limiting hole, a third inclined surface is provided on the protrusion, the locking part moves up and down along the third inclined surface, and the locking part can move upward along the third inclined surface of the protrusion to disengage from the protrusion and abut against the locking. The solid trigger and sliding member have a more robust and stronger structure, which greatly improves the service life. At the same time, the up and down movement of the solid trigger promotes the horizontal movement of the sliding member, which is conducive to achieving the unlocking and locking effects.

[0047] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0048] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 12As shown, a threadless quick-opening cup lid includes a lid body 1 and a pull-lock assembly 2 disposed on the lid body 1. A sealing element 3, made of soft silicone, is provided on the pull-lock assembly 2. The pull-lock assembly 2 passes through the lid body 1 and the sealing element 3. The pull-lock assembly 2 includes a lifting element 21 that passes through the lid body 1 and the sealing element 3. The lifting element 21 has a solid trigger element 22 that moves back and forth along the lifting element 21, and a horizontally moving sliding element 23. The inner wall of the lid body 1 has a locking mechanism that cooperates with the sliding element 23. Part 24, the downward movement of the solid trigger 22 causes the slider 23 to move horizontally to one side, and the locking part 24 will disengage from the slider 23 and be locked. The lifting part 21 moves downward relative to the cover 1, thereby causing the seal 3 on the lifting part 21 to deform back to its original shape. When the lifting part 21 is lifted, the lifting part 21 moves upward relative to the cover 1, and the locking part 24 causes the slider 23 to move horizontally to one side until the locking part 24 is locked by the slider 23. Finally, the seal 3 on the lifting part 21 is squeezed, expanded and deformed.

[0049] Example 2: This can be explained based on Example 1, such as... Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 12As shown, the solid trigger 22 includes a solid trigger body 221 that can move up and down in the lifting member 21. A return member 222 is provided between the solid trigger body 221 and the lifting member 21. A first inclined surface 2221 is provided on the solid trigger body 221. The sliding member 23 includes a sliding block 231 that can move back and forth horizontally in the lifting member 21. A reset member 232 is provided between the sliding block 231 and the lifting member 21. A sliding position 233 is provided on one side of the sliding block 231 for the solid trigger body 221 to pass through. A second inclined surface 2331 that cooperates with the first inclined surface 2221 is provided on the sliding position 233. A locking part 24 is provided on the other side of the sliding block 231. The protrusion 2311 and the lifting member 21 are provided with a limiting hole. The protrusion 2311 moves back and forth in the limiting hole. The protrusion 2311 is provided with a third inclined surface 2312. The locking part 24 moves up and down along the third inclined surface 2312. The locking part 24 can move upward along the third inclined surface 2312 of the protrusion 2311 to disengage from the protrusion 2311 and abut against the locking part 24. In this way, the lifting member 21 moves downward relative to the cover 1, thereby causing the seal 3 on the lifting member 21 to deform back to its original shape. The locking part 24 can move downward along the third inclined surface 2312 of the protrusion 2311 until the protrusion 2311 abuts against the locking locking part 24. Finally, the seal 3 on the lifting member 21 is squeezed, expanded and deformed. The protrusion 2311 and the sliding block 231 are integrally formed, which greatly improves the structural strength. To further explain, both the return element 222 and the reset element 232 are springs, which facilitates the reset of the solid trigger 221 and the sliding block 231, respectively. Two return elements 222 are used, which further ensures that the solid trigger 221 can be smoothly reset after the pressing force is removed. The solid trigger 221 has symmetrically distributed positioning posts for positioning and installing the return element 222, while a positioning rod for positioning and installing the reset element 232 is provided on one end face of the sliding block 231.

[0050] Among them, such as Figure 10 As shown, the lifting component 21 has a mounting hole for mounting a solid trigger 22 and a mounting cavity for mounting a sliding component 23. The solid trigger 22 moves back and forth in the mounting hole, while the sliding component 23 moves back and forth horizontally in the mounting cavity. The lifting component 21 includes a first housing 211 and a second housing 212 that engage with each other. A base 213 integrally formed with the first housing 211 is provided at the lower part of the first housing 211. After the first housing 211 and the second housing 212 are engaged, a mounting hole and a mounting cavity are formed inside. After the first housing 211 and the second housing 212 are engaged, a lifting hole 214 for lifting is formed at the upper part. This arrangement is reasonable and easy to implement. A sealing component 3 is fitted on the engaged housing 211 and the second housing 212 on the upper surface of the base 213. During use, the base 213 moves towards the cover 1, thereby causing the sealing component 3 to be squeezed and deformed.

[0051] Example 3: Based on Example 2, such as... Figure 2 , Figure 4 and Figure 6 As shown, it also includes an exhaust assembly 25 disposed on the lower end face of the lifting member 21. The downward movement of the solid trigger member 22 will cause the exhaust assembly 25 to open, which facilitates pre-venting. Specifically, the exhaust assembly 25 includes an exhaust rod 251 disposed on the lower end face of the lifting member 21 that can move up and down. The exhaust rod 251 is located below the solid trigger member 22. When the solid trigger member 22 moves downward, it can resist the downward movement of the exhaust rod 251. The exhaust rod 251 is provided with a compression member 252. In this embodiment, the compression member 252 is a spring, which facilitates the return of the exhaust rod 251. Furthermore, a sealing ring 253 is provided on the exhaust rod 251 exposed on the lower end face of the lifting member 21, which helps to improve the venting and sealing effect.

[0052] Example 4: Based on Example 2 or Example 3, such as... Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 11 As shown, the device also includes a safety lock 26 on the lifting member 21 to prevent the solid trigger member 22 from being accidentally opened. The solid trigger member 22 can only be pressed when the safety lock 26 is open, and cannot be pressed when the safety lock 26 is closed. Specifically, the safety lock 26 includes a slide rail 261 on the lifting member 21, a sliding lock 262 that slides back and forth on the slide rail 261, and a slide rail 263 on the upper surface of the solid trigger member 22. The slide rail 261 and the slide rail 263 form an annular slide rail. When the sliding lock 262 slides onto the slide rail 263, it prevents the solid trigger member 22 from being accidentally triggered. When the sliding lock 262 slides away from the slide rail 263 and onto the slide rail 261, the solid trigger member 22 can be pressed. In this embodiment, the sliding lock 262 is arc-shaped. To further explain, protrusions are provided on the outer surface of the slide lock 262. In this embodiment, the protrusions are spaced apart on the outer surface of the slide lock 262. This helps to increase friction and makes it easier for the slide lock 262 to rotate back and forth on the slide rail 261.

[0053] Example 5: This can be described based on Example 1, Example 2, Example 3, or Example 4, such as... Figure 12As shown, the cover 1 has a device hole for installing the pull-locking assembly 2. A snap-fit ​​portion 24, integrally formed with the cover 1, is provided on the inner wall of the device hole. This design is reasonable and facilitates the installation of the pull-locking assembly 2, making the integral structure of the snap-fit ​​portion 24 and the cover 1 more robust. It also facilitates relative movement between the cover 1 and the pull-locking assembly 2, thereby allowing the seal 3 to be deformed and return to its original shape. In this embodiment, the snap-fit ​​portion 24 is a cylindrical column for ease of implementation.

[0054] Example 6: Based on Example 1, Example 2, Example 3, Example 4, or Example 5, such as... Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, this utility model also provides a cup, including a cup body 10, with a threadless quick-opening cup lid 20 as described above installed at the opening of the cup body 10. Further, the inner wall of the opening of the cup body 10 is provided with a receiving groove. In use, a sealing connection is achieved by squeezing and expanding the sealing member 3 into the receiving groove.

[0055] This invention first slides the sliding lock 262 away from the slide rail 263 and onto the slide rail 261. Then, the solid trigger body 221 can be pressed down. The solid trigger body 221 moves downward in the lifting member 21, compressing the return member 222. At the same time, the lower end face of the solid trigger body 221 will cause the exhaust assembly 25 to open, venting the cup body 10 through the exhaust assembly 25. Furthermore, the solid trigger body 221 on the solid trigger body 221 cooperates with the second inclined surface 2331 on the sliding block 231 to cause the sliding block 23 to move. 1. Moving the reset member 232 to one side compresses the reset member 232, causing the snap-fit ​​part 24 on the cover 1 to move upward along the third inclined surface 2312 of the protrusion 2311, disengaging from the protrusion 2311 and abutting against the lock. Pulling the locking assembly 2 moves downward relative to each other in the cover 1, ultimately causing the seal 3 on the lifting member 21 to return to its initial position. Consequently, the seal 3 will not seal and lock with the receiving groove, which facilitates the removal of the threadless quick-opening cup lid 20. After the external force of pressing the solid trigger 221 is removed, in Under the action of the return member 222, the solid trigger 221 returns to its original position, the sliding block 231 resets under the action of the reset member 232, and the exhaust assembly 25 returns to its original position. When it is necessary to tighten the threadless quick-opening cup lid 20 onto the opening of the cup body 10, it is only necessary to pull the lifting member 21 upward. The lifting member 21 moves upward relative to the lid body 1, so that the locking part 24 on the lid body 1 will move downward along the third inclined surface 2312 of the protrusion 2311 until the protrusion 2311 abuts against the locking part 24 (wherein the locking part 24 will cause the sliding block 231 to move downward). 1. Move the reset member 232 to one side to compress the reset member 232 until the locking part 24 is located at the lower end face of the protrusion 2311 and is blocked and locked. Under the action of the spring force of the reset member 232, the sliding block 231 is reset, so that the locking part 24 is located at the lower end face of the protrusion 2311 and is blocked and locked. Finally, the seal 3 on the lifting member 21 can expand and deform along the seal 3. The seal 3 moves axially to seal and fill into the receiving groove. This is conducive to the threadless quick-opening cup lid 20 being tightly closed on the opening of the cup body 10.

[0056] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, springs and sealing rings that are mature in the existing technology, and will not be described in detail here.
