Description

Technical Field

[0001] This utility model relates to the field of cup technology, and in particular to a self-locking glass water-sealing cup lid and a water cup. Background Technology

[0002] In the prior art, water cups (including thermos cups and similar products) have a sealing ring between the lid and the mouth of the cup body for sealing. The sealing ring is usually a silicone sealing ring. However, in actual use, the silicone sealing ring can still cause leakage. This can lead to leakage when the cup is tightly closed and carried, which does not meet the user's needs. Utility Model Content

[0017] (III) The technical effects to be achieved

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Firstly, the inner wall of the inner cover of this utility model has evenly spaced slots, and the inner cover is provided with a self-locking device that can radially contract and radially expand. The inner wall of the outer cover is provided with a groove for causing the self-locking device to radially expand. A protrusion is formed between the inner walls of the outer cover between adjacent grooves. In the initial state, the self-locking device is in contact with the groove. When the outer cover is rotated, the self-locking device switches back and forth between the groove and the protrusion, thus switching between radial expansion and radial contraction. The self-locking device can achieve self-locking and unlocking, which is beneficial to meeting the user's needs.

[0020] Secondly, the inner cover of this utility model is provided with a glass water-sealing component for sealing water, and the outer wall of the inner cover is evenly arranged with inclined slide grooves. The outer cover is provided with a rolling component that slides in the corresponding inclined slide groove. The outer cover does not need to rotate 360° by sliding the rolling component in the inclined slide groove, thus ending the cumbersome operation of 360° rotation, making it easier and more convenient for users to operate.

[0021] Thirdly, the cup body of this utility model has a glass ring installed at the mouth, and evenly distributed locking protrusions and locking grooves on the outer wall of the cup body. When the self-locking glass sealing cup lid is placed on the cup body, the locking protrusions fall into the locking grooves. When the self-locking glass sealing cup lid is rotated, the self-locking device changes from an unlocked state to a self-locked state locked in the locking groove, or the self-locking device changes from a self-locked state locked in the locking groove to an unlocked state. At the same time, the glass sealing component moves downward and makes close contact with the glass ring. When the self-locking glass sealing cup lid is rotated in the opposite direction, the self-locking device changes from a self-locked state locked in the locking groove to an unlocked state. This application on the water cup eliminates the need for 360-degree rotation to open and close, making it easier and more convenient for users. At the same time, the glass-to-glass sealing method eliminates the possibility of water or air leakage, making it more convenient for users to carry the water cup. Furthermore, since there is no plastic contact with water, zero pollution is achieved, making drinking water safer and healthier. Attached Figure Description

[0055] 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.

[0056] Example 1: See Figures 1 to 19A self-locking glass water cup lid includes an inner lid 1 and an outer lid 2 disposed on the inner lid 1. The outer lid 2 is fitted onto the outer surface of the inner lid 1 and can rotate on the inner lid 1. The inner wall of the inner lid 1 has evenly spaced slots 11. The inner lid 1 is provided with a self-locking device 3 capable of radial contraction and radial expansion. The inner wall of the outer lid 2 has grooves 21 for causing the self-locking device 3 to expand radially. Protrusions 22 are formed between the inner walls of the outer lid 2 and adjacent grooves 21, allowing the self-locking device 3 to contract radially. In its initial state, the self-locking device 3 is in contact with the grooves 21. When the outer lid 2 is rotated, the self-locking device 3 can be radially contracted. The self-locking device 3 switches back and forth between the groove 21 and the protrusion 22, thereby enabling the self-locking device 3 to switch back and forth between radial expansion and radial contraction, which is conducive to unlocking and self-locking. The inner cover 1 is provided with a glass water-sealing component 4 for sealing water. The glass water-sealing component 4 helps to better meet the water sealing effect and prevent water leakage. The outer wall of the inner cover 1 is evenly arranged with inclined slide grooves 12, while the outer cover 2 is provided with a rolling component 5 that slides in the corresponding inclined slide groove 12. By the rolling component 5 sliding in the inclined slide groove 12, the outer cover 2 does not need to rotate 360°, ending the cumbersome operation method of 360° rotation.

[0057] Example 2: This can be explained based on Example 1, such as... Figures 1 to 5 as well as Figure 9 and Figure 10 As shown, an outer shell 6 is fixed to the outer cover 2. The outer shell 6 can drive the outer cover 2 to rotate on the inner cover 1. The outer shell 6 provides a certain degree of protection for both the outer cover 2 and the inner cover 1. Furthermore, the outer shell 6 is made of stainless steel, which facilitates manufacturing.

[0058] Example 3: This can be described based on Example 1 or Example 2, such as... Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the glass water-sealing component 4 includes a mounting base 41 located inside the inner cover 1. The mounting base 41 is provided with an inverted hook 42 that passes through the upper surface of the inner cover 1. A limiting ring 43 is provided between the inner cover 1 and the outer cover 2. The limiting ring 43 is provided with an inverted hook 44 for fixing to the upper surface of the outer cover 2. The inverted hook 42 cooperates with the limiting ring 43 to prevent the mounting base 41 from detaching from the inner cover 1. A glass plate 45 is provided on the lower surface of the mounting base 41. Water sealing is achieved through the glass plate 45, surpassing the existing technology of using silicone sheets for water sealing, resulting in a better sealing effect. Furthermore, the glass plate 45 is made of borosilicate glass, microcrystalline glass, or heat-resistant glass, which are widely available and easy to implement.

[0059] Among them, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a fixing plate 46 is provided on the mounting base 41, and a glass plate 45 is provided on the fixing plate 46. A reset member 47 for resetting the fixing plate 46 is provided at the center of the inner cover 1. The reset member 47 helps to maintain a downward pressure on the fixing plate 46 and the glass plate 45. The fixing plate 46 is provided with an inverted hook 461 to prevent it from detaching from the mounting base 41, and a placement groove 462 for placing the reset member 47 is also provided on the fixing plate 46. This arrangement helps to ensure that the glass plate 45 is always subjected to a downward force through the reset member 47. The reset member 47 can also be omitted to meet the usage requirements. Further explanation is provided below. Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the reset element 47 is made of a spring or a silicone ring, which is easy to implement; or, a spring body 48 is provided between the mounting base 41 and the glass plate 45, which is beneficial to the springback of the glass plate 45. The spring body 48 is made of a silicone ring, which is easy to implement.

[0060] Among them, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the hooks 42 and the bracket 41 are integrally formed, which greatly improves the structural strength. The hooks 42 are evenly spaced on the bracket 41. In this embodiment, three hooks 42 are used, which helps to make the bracket 41 operate more stably. The limiting ring 43 and the hooks 44 are integrally formed. The hooks 44 are evenly spaced on the limiting ring 43. In this embodiment, six hooks 44 are used, which helps to make the connection with the outer cover 2 more secure.

[0061] Example 4: This can be described based on Example 1, Example 2, or Example 3, such as... Figure 3 , Figure 11 , Figure 13 and Figure 14As shown, the self-locking device 3 includes mounting holes 31 evenly spaced on the inner cover 1. Each mounting hole 31 houses a lever-operated hook 32. All hooks 32 on the inner cover 1 are bound together by an elastic body 33. The inner wall of the outer cover 2 has grooves 21 corresponding to the number of hooks 32. Initially, the back of each hook 32 is in the groove 21, which facilitates the hooks being in a released state. During use, simply rotating the outer cover 2 causes the back of the hooks 32 to switch between the groove 21 and the protrusion 22, ultimately enabling the self-locking and unlocking of the self-locking device 3. In this embodiment, three hooks 32 are used, a reasonable arrangement that facilitates placement on the inner cover 1.

[0062] Among them, such as Figure 14 As shown, each hook 32 includes an upper body 321 and a lower body 322 integrally formed with the upper body 321. An arc-shaped groove 323 is provided on the upper body 321, located on the outer surface of the upper body 321. The arc-shaped groove 323 facilitates the placement of the elastic body 33. A latch 324 is provided on the lower body 322, located on the inner surface of the lower body 322. Rotating shafts 325 are provided on both sides of the upper body 321, located on the inner cover 1. The lower body 322 contacts the inner wall of the outer cover 2. In use, the hook 32 can perform lever movement by using the rotating shafts 325 as a fulcrum. The lever movement of the hook 32 is achieved by the rotation of the outer cover 2 relative to the inner cover 1, thereby causing the back of the lower body 322 of the hook 32 to be concave. When the groove 21 or protrusion 22 is rotated, the hook 32 is used to perform lever movement with the rotating shaft 325 as the fulcrum. In the initial state, the back of the lower body 322 of the hook 32 is located in the groove 21, and each hook 32 is in the loose state, that is, all the hooks 32 are in the radially expanded state. When the outer cover 2 is rotated, the back of the lower body 322 of the hook 32 changes from the groove 21 to the protrusion 22. In this way, the protrusion 22 of the outer cover 2 pushes the hook 32 with the rotating shaft 325 as the fulcrum, so that the hook 32 can perform lever movement. At this time, the hook 32 moves inward, and each hook 32 is in the self-locking state, that is, all the hooks 32 are in the radially contracted state. In this way, the self-locking and unlocking of the self-locking device 3 can be switched back and forth by rotating the outer cover 2, which is beneficial to meet the user's needs.

[0063] Among them, such as Figure 12 and Figure 13 As shown, the elastic body 33 is an elastic ring, such as a spring coil. This design is more conducive to all the hooks 32 performing lever movements on the inner cover 1.

[0064] Example 5: This can be described based on Example 1, Example 2, Example 3, or Example 4, such as... Figure 7 and Figure 11As shown, the inclined slide groove 12 includes a horizontal slide 121 and an inclined slide 122 disposed on the outer surface of the inner cover 1. The horizontal slide 121 and the inclined slide 122 are connected, and the rolling element 5 can slide back and forth on the horizontal slide 121 and the inclined slide 122. This is beneficial because the outer cover 2 does not need to rotate 360° on the inner cover 1. Further, the inclined slide 122 has an angle of 75° with the horizontal plane. This is beneficial because the outer cover 2 can rotate 75° to lock and unlock the self-locking device 3, avoiding the need for at least 360° starting with traditional threads, which often requires multiple rotations. It also avoids the phenomenon that threads must be precisely aligned to tighten. At the same time, it eliminates the need for two-handed operation and repeated checks for tightening during rotation (avoiding time-consuming and laborious operation), making it more practical and better meeting the user's operational needs. Further explanation is provided, as... Figure 15 , Figure 16 and Figure 17 As shown, each inclined slide 122 is provided with an elastic steel component 123 (in this embodiment, a U-shaped locking bar is used; the elastic steel mainly includes phase change induced elastic steel, CK75 spring steel, stainless steel spring wire, or SUP6 spring steel, etc.). This helps to prevent the rolling component 5 from easily rolling out and rolling in from the inclined slide 122. There is a clicking sound when the rolling component 123 is rolled, which helps to increase the difficulty of rolling and prevents it from being easily opened by mistake.

[0065] Among them, such as Figure 5 and Figure 11 As shown, the rolling element 5 is made of steel balls, and the steel balls can rotate on their own in the outer cover 2, which is more conducive to the operation of the rolling element 5.

[0066] In this embodiment, three inclined slide grooves 12 and three rolling elements 5 are used. One rolling element 5 rolls back and forth in one inclined slide groove 12. This arrangement is reasonable and facilitates the back and forth rotation of the outer cover 2 relative to the inner cover 1, making the rotation more stable and reliable.

[0067] Example 6: This can be described based on Example 1, Example 2, Example 3, Example 4, or Example 5, such as... Figure 3 , Figure 5 , Figure 10 , Figure 11 , Figure 18 and Figure 19As shown, the inner cover 1 is provided with a rotating limiting seat 7, and a hook 71 is integrally formed with the rotating limiting seat 7. The hook 71 cooperates with the inner cover 1 to prevent the rotating limiting seat 7 from detaching from the inner cover 1. The outer cover 2 is provided with a central hole 23. The upper part of the rotating limiting seat 7 is located in the central hole 23. The inner side wall of the central hole 23 is provided with recesses distributed at intervals. The upper end face of the rotating limiting seat 7 is provided with a device groove. A compression spring 72 is installed in the device groove. A spring pin 73 is provided on the compression spring 72. The upper end face of the rotating limiting seat 7 at the device groove position is provided with a notch for the spring pin 73 to enter and exit. When the outer cover 2 rotates, the spring pin 73 contacts the recess of the central hole 23, which facilitates the back and forth movement of the spring pin 73, thereby producing a rotating collision sound. The rotation is tactile and helps the user to know that it is rotating.

[0068] Example 7: This can be described based on Example 1 or Example 2, such as... Figures 20 to 28 As shown, this utility model also provides a water cup, including a cup body 10. A glass ring 20 is installed at the mouth of the cup body 10. Evenly spaced locking protrusions 30 are provided on the outer wall of the mouth of the cup body 10, and a locking groove 40 is provided on the outer wall of the mouth of the cup body 10. When the self-locking glass-sealed water cup lid 50 is placed on the mouth of the cup body 10 as described above, the locking protrusions 30 fall into the locking groove 11, thus restricting the rotation of the inner lid 1. When the self-locking glass-sealed water cup lid 50 is rotated (clockwise), the self-locking device 3 changes from an unlocked state to a self-locked state locked in the locking groove 40, or the self-locking device 3 changes from a self-locked state locked in the locking groove 40 to an unlocked state. Simultaneously, the glass sealing component 4 moves downwards and comes into close contact with the glass ring 20, sealing the water cup. The glass plate 45 and glass ring 20 in component 4 seal off water vapor through a self-sealing principle upon contact with water. This ensures that the self-locking glass water-sealing lid 50 and the cup body 10 will not leak water or air, avoiding the need for contact with plastic in existing technologies. From adding water to drinking, there is no contact with plastic, achieving zero pollution. Utilizing the properties of glass, the glass plate 45 and glass ring 20 can self-adhere to each other after contact, forming a seal that releases air and seals water. This facilitates a tighter seal of the self-locking glass water-sealing lid 50 on the cup body 10. When the self-locking glass water-sealing lid 50 is rotated in the opposite direction (counterclockwise), the self-locking device 3 changes from a locked state in the locking groove 40 to an unlocked state, making it easy to remove the self-locking glass water-sealing lid 50 from the cup body 10. This utility model is applicable to stainless steel cups, plastic cups, titanium cups, and specially made glass cups and related liquid containers, etc. Further explanation: the glass ring 20 is made of borosilicate glass, microcrystalline glass, or heat-resistant glass, which are widely available and easy to implement. Among them, such as Figures 20 to 24As shown, the glass ring 20 is truncated cone-shaped, and a sealing ring 201 is provided between the lower end face of the glass ring 20 and the cup body 10. This facilitates the up-and-down movement of the glass ring 20 and allows for better contact between the glass ring 20 and the glass plate 45 for sealing water. A pressure ring 202 is provided on the mouth of the cup body 10 to fix the glass ring 20. The truncated cone-shaped glass ring 20 and the pressure ring 202 have better contact, which helps to better fix the glass ring 20 on the mouth of the cup body 10. The outer surface of the truncated cone-shaped glass ring 20 is inclined, and the inner surface is straight. This is more conducive to meeting the requirements of fixing and sealing water. The sealing ring 201 is located between the lower end face of the glass ring 20 and the upper end face of the cup body 10. The glass ring 20 is preferably a spring ring or a silicone ring for easy implementation. In this embodiment, four locking protrusions 30 are used, and the four locking protrusions 30 are evenly spaced on the outer wall of the cup mouth of the cup body 10. This makes it easier for the locking protrusions 30 to engage with the locking groove 11, resulting in a more stable connection between the self-locking glass water cup lid 50 and the cup body 10, and preventing the inner lid 1 from rotating. The pressure ring 202 can also be omitted (e.g., Figures 25 to 28 (As shown).

[0069] like Figures 1 to 28As shown, initially, the self-locking device 3 in the self-locking glass water cup lid 50 is in the initial released state (i.e., the radially expanded state). When the self-locking glass water cup lid 50 is placed on the mouth of the cup body 10, the evenly distributed locking protrusions 30 on the outer side wall of the cup body 10 fall into the locking grooves 11 on the inner side wall of the inner lid 1. At this time, the inner lid 1 cannot rotate at the mouth of the cup body 10. Then, rotating the outer shell 6 (clockwise) will cause the outer shell 6 to rotate the inner lid 2 together (clockwise). The groove 21 on the inner side wall of the inner lid 2 contacts the locking hook 32 and becomes an inner... The protrusion 22 on the inner wall of the lid 2 contacts the hook 32, which pushes the hook 32 to perform a lever movement on the inner lid 1. The lower part of the hook 32 moves towards the center of the inner lid 1, and all the lower parts of the hooks 32 change from radial expansion to radial contraction. In this way, the hooks 32 are locked in the locking groove 40 of the cup body 10, thus realizing the self-locking glass water-sealing lid 50 being tightly closed on the mouth of the cup body 10. At the same time, the glass plate 45 in the glass water-sealing component 4 moves downward and seals the water vapor between it and the glass ring 20 on the cup body 10 through the principle of self-sealing upon contact with water. This design ensures that the self-locking glass water-sealing lid 50 and the cup body 10 will not leak water or air, avoiding the need for contact with plastic in existing technologies. From adding water to drinking, there is no plastic contact, achieving zero pollution. Utilizing the properties of glass, the glass plate 45 and glass ring 20 can self-adhere to each other to form a seal, preventing air from escaping and water leakage. This helps to ensure the self-locking glass water-sealing lid 50 is more tightly sealed to the mouth of the cup body 10. When the outer shell 6 is rotated in the opposite direction (counterclockwise), the outer shell 6 will also cause the inner lid 2 to rotate in the opposite direction (counterclockwise). The convex shape on the inner wall of the inner lid 2... When the hook 22 contacts the hook 32, the groove 21 on the inner side wall of the inner cover 2 contacts the hook 32. At this time, the hook 32 performs lever movement on the inner cover 1. The lower part of all the hooks 32 changes from a radially contracted state to a radially expanded state. At this time, the self-locking device 3 returns to its initial state. In this way, the hook 32 will disengage from the locking groove 40 of the cup body 10. The glass plate 45 in the glass sealing component 4 can be returned to its original position under the action of the restoring force of the reset component 47 or the spring body 48. In this way, the self-locking glass sealing cup lid 50 can be removed from the cup mouth of the cup body 10.

[0070] 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 sealing rings and springs that are mature in the existing technology, and will not be described in detail here.
