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 a water cup. Background Technology

[0002] Cups are a common type of utensil in daily life, often used to hold tea or alcohol. Generally, a cup consists of a cup and a lid, connected by threads. These threads mesh at the joint; for example, the cup may have an external thread at the top and an internal thread on the inner wall of the lid, or vice versa. However, in daily use, when hot water is inside the cup, after cooling for a period of time, a negative pressure forms inside the cup, causing the lid to stick and become difficult or impossible to open. This inconveniences the user and affects their experience. Furthermore, applying significant force to turn the lid can also cause problems. This can cause hot water to spill from the thermos, resulting in burns. This has led to the development of inventions such as the Chinese invention patent CN105059693B, which discloses an expandable container sealing plug. This plug uses an annular elastic seal with a V-shaped cross-section. While it also seals the container tightly, the V-shaped cross-section after expansion makes it more convenient and less strenuous to use. However, this technology is relatively simple, and manufacturers need different solutions to achieve the same sealing effect and facilitate user operation. Utility Model Content

[0049] 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.

[0050] Example 1: See Figure 1 , Figure 2 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 5 A threadless quick-opening cup lid includes an upper cover 1 and an elastic seal 2. The upper cover 1 has an upper rack guide seat 3 and a lower rack guide assembly 4 that can move relative to the upper rack guide seat 3. The elastic seal 2 is disposed between the upper rack guide seat 3 and the lower rack guide assembly 4. The upper cover 1 has a switch assembly 5 for unlocking the lower rack guide assembly 4. The relative movement between the upper rack guide seat 3 and the lower rack guide assembly 4 causes the elastic seal 2 to deform and return to its initial state. Figure 1 , Figure 2 , Figure 10 , Figure 11 and Figure 12 As shown, pressing the upper cover 1 causes the upper rack guide seat 3 to move with the upper cover 1. The upper rack guide seat 3 and the lower rack guide assembly 4 move relative to each other, compressing and deforming the elastic seal 2. After the lower rack guide assembly 4 is fixed on the upper cover 1, it causes the elastic seal 2 to deform and be fixed in place. Figure 1 , Figure 13 , Figure 14 and Figure 15 As shown, when the switch assembly 5 is activated, the switch assembly 5 will cause the lower rack guide assembly 4 to disengage from the upper cover 1. After the upper rack guide seat 3 and the lower rack guide assembly 4 move relative to each other, the elastic seal 2 will return to its initial state (original state) due to the absence of external pressure.

[0051] Example 2: This can be explained based on Example 1, such as... Figure 1 and Figure 6 As shown, the upper rack guide seat 3 includes a fixed seat 31 mounted on the upper cover 1, and guide posts 32 and racks 33 integrally formed with the fixed seat 31. The guide posts 32 and racks 33 are distributed in pairs, as shown in the figure. Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 14 As shown, the lower rack guide assembly 4 includes a guide plate 41 that penetrates the fixed base 31. A toothed block 42 that meshes with the corresponding rack 33 is provided on the guide plate 41. A guide post 32 is located on the surface of the corresponding toothed block 42. A base 43 is integrally formed with the guide plate 41. A gear 44 is provided between the toothed block 42 and the rack 33, facilitating relative movement (up and down movement) between the lower rack guide assembly 4 and the upper rack guide seat 3 via the gear 44. A notch 45 is provided on the guide plate 41, and correspondingly distributed locking pieces 46 are provided on both sides of the notch 45. The upper cover 1 is provided with a slot 47 for locking the locking piece 46. When the switch assembly 5 is activated, it forces the locking piece 46 to disengage from the slot 47. This facilitates the elastic seal 2 to return to its initial state (original state) after the upper rack guide seat 3 and the lower rack guide assembly 4 move relative to each other, as there is no external force pressing. The guide plate 41 at the notch 45 is provided with an exhaust assembly 48 for venting gas. When the switch assembly 5 is activated, it forces the exhaust assembly 48 to move downward, and when the switch assembly 5 is deactivated, the exhaust assembly 48 returns to its initial state upward. In this embodiment, two gears 44 are used, which helps to make the relative movement of the lower rack guide assembly 4 and the upper rack guide seat 3 more balanced.

[0052] Among them, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the locking component 46 includes a buckle 461 on a guide plate 41 located on both sides of the notch 45. Each buckle 461 is provided with a return member 462. One end of the return member 462 contacts the buckle 461, and the other end of the return member 462 contacts the inner wall of the guide plate 41. This facilitates the compression and extension of the buckle 461. In this embodiment, the return member 462 is a spring, which is convenient to implement and also facilitates the extension and compression of the buckle 461.

[0053] Among them, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 14As shown, the exhaust assembly 48 includes an exhaust needle 481 that can move up and down in the guide plate 41. The exhaust needle 481 is connected to the guide plate 41 by a reset member 482. In this embodiment, the exhaust needle 481 is in the shape of a "towel" character. Two reset members 482 are used, which is more conducive to the exhaust needle 481 returning to its original state. The reset member 482 is a spring. A sealing sleeve 483 is provided on the lower end surface of the exhaust needle 481. The guide plate 41 is provided with an installation hole for the up and down movement of the exhaust needle 481 and the sealing sleeve 483.

[0054] Embodiment 3: It can be described based on Embodiment 2. For example, Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, the upper cover member 1 includes an upper cover body 11 and a positioning sleeve 12 provided on the lower end surface of the upper cover body 11 for fixing the gear 44. The fixed seat 31, the guide post 32 and the rack 33 move back and forth in the positioning sleeve 12. An elastic sealing member 2 is sleeved on the positioning sleeve 12. The lower end surface of the elastic sealing member 2 is on the chassis 43. A card slot 47 is provided on the lower surface of the upper cover body 11. Pressing the upper cover member 1 like this realizes the relative movement of the upper rack guide seat 3 and the lower rack guide assembly 4. In this way, when the lower rack guide assembly 4 moves upward, the card member 46 is stuck into the card slot 47, so as to fix the elastically deformed elastic sealing member 2. When the pressing switch assembly 5 is activated, the switch assembly 5 will cause the card member 46 in the lower rack guide assembly 4 to脱离 the card slot 47. After the relative movement of the upper rack guide seat 3 and the lower rack guide assembly 4, the elastic sealing member 2 returns to its initial state (original state) because there is no external force extrusion. Further explanation, a carrying handle ring 13 is provided on the upper end surface of the upper cover body 11. A decorative ring 14 that can rotate back and forth is provided in the carrying handle ring 13. A compression member 15 is provided on the upper cover body 11. A round bead 16 is provided on the compression member 15. The round bead 16 is in contact with the circumferential surface of the decorative ring 14. The circumferential surface of the decorative ring 14 is provided with concavo-convex shapes. When the decorative ring 14 rotates inside the carrying handle ring 13, there is a rotating sound, which is more textured and interesting during rotation, and is conducive to the user having a decompression effect during use. In this embodiment, the compression member 15 is a spring, which is easy to implement.

[0055] Among them, for example, Figure 1 、 Figure 2 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15As shown, the elastic seal 2 uses a rubber ring, which is easy to implement.

[0056] Among them, such as Figure 2 , Figure 3 , Figure 11 and Figure 14 As shown, the positioning sleeve 12 includes a sleeve body and a positioning post disposed on the inner side wall of the sleeve body for fixing the gear 44. This arrangement is reasonable and easy to implement.

[0057] Example 4: This can be described based on Example 2 or Example 3, such as... Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 11 and Figure 14 As shown, the switch assembly 5 includes an upper cover 1 located between slots 47, on which a mounting groove is provided. A sliding seat 51 is provided on the mounting groove, and the sliding seat 51 slides back and forth along the mounting groove. The end of the sliding seat 51 that contacts the card 46 is set in an inclined shape. This design is more conducive to the sliding seat 51 pushing the card 46 out of the slot 47 after sliding into the mounting groove. A spring-loaded element 52 is provided on the sliding seat 51, which is conducive to the sliding seat 51 returning to its original state after the external force of pressing the sliding seat 51 is removed. A safety switch 53 is provided on the sliding seat 51. The sliding seat 51 can only be pressed through the safety switch 53 after the safety switch 53 is opened. Otherwise, the safety switch 53 cannot be pressed, and therefore the sliding seat 51 cannot be pressed, which helps to avoid accidental activation. The spring-loaded element 52 is a spring, which is easy to implement.

[0058] Among them, such as Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 11 and Figure 14As shown, the safety switch 53 includes a blocking block 531 positioned in the mounting groove and a switch lock 532 that can slide back and forth on the surface of the sliding seat 51. The surface of the sliding seat 51 has a groove 511 and a protrusion 512. A push foot and a protrusion are provided on the surface of the switch lock 532, which corresponds to the surface of the sliding seat 51. The switch lock 532 can move back and forth on the surface of the sliding seat 51. When the push foot is in the groove 511, it cannot contact the bottom surface of the groove 511. The protrusion slides back and forth on the protrusion 512. The switch lock 532 below the protrusion is blocked by the blocking block 531, thus preventing the switch lock 532 from being pushed into the mounting groove, and consequently, preventing the sliding seat 51 from being pushed into the mounting groove by the switch lock 532. The movement helps to avoid accidental operation that could push the sliding seat 51. When the switch lock 532 moves away from the blocking block 531, the protrusion 512 moves along the protrusion, the push foot will disengage from the groove 511, and the push foot will contact the surface of the sliding seat 51. The switch lock 532 below the protrusion will disengage from the blocking block 531, and finally push the switch lock 532. The protrusion on the switch lock 532 will push the protrusion 512 on the surface of the sliding seat 51, and the push foot on the switch lock 532 will push the surface of the sliding seat 51, thereby causing the sliding seat 51 to slide into the mounting groove. At the same time, the spring member 52 is compressed, so the sliding seat 51 will cause the locking member 46 to disengage from the locking groove 47. When the external force is removed, the spring member 52 will cause the sliding seat 51 to return to its original state.

[0059] like Figure 2 , Figure 8 , Figure 9 , Figure 11 and Figure 14 As shown, in this embodiment, the groove 511 is horizontal, the protrusion 512 is on the surface of the sliding seat 51 below the groove 511, and the blocking block 531 is located below the opening of the mounting groove. This arrangement is beneficial for the switch lock 532 to slide up and down. When the switch lock 532 slides upward, it is beneficial for the safety of the switch lock 532 to be opened and for the sliding seat 51 to be pressed down to open. When the switch lock 532 slides downward, it cannot be pressed inward. If horizontal back-and-forth movement is to be achieved, it is only necessary to arrange the groove 511 and the blocking block 531 vertically.

[0060] Example 5: This can be described based on Example 1, Example 2, Example 3, or Example 4, such as... Figure 16 , Figure 17 , Figure 18 and Figure 19As shown, this utility model also provides a water cup, including a cup body 10. An O-ring 100 is provided on the inner side wall of the cup mouth of the cup body 10. The aforementioned threadless quick-opening cup lid 20 is installed on the cup mouth of the cup body 10. The threadless quick-opening cup lid 20 is squeezed and deformed to make close contact with the O-ring 100, which is conducive to sealing and connection, and also helps to ensure that there is no water leakage or air leakage, resulting in a better sealing effect. To further explain, the O-ring 100 is a raised O-ring 100 (recessed towards the cup opening), meaning that the cup opening of the cup body 10 has a raised O-ring 100. This allows the elastic sealing element 2 in the threadless quick-opening cup lid 20 to deform into a flat O-shape after compression, making tight contact with the raised O-ring 100 at the cup opening. The elastic sealing element 2, after deformation, is arranged along the lower surface of the O-ring 100. This design ensures that the cross-section of the elastic sealing element 2 in the cup opening of the threadless quick-opening cup lid 20, when compressed, does not form a V-shape, providing a different technical solution to achieve a tight seal. This facilitates a sealed connection and helps prevent water and air leakage, resulting in a better sealing effect. Figure 16 As shown, when the threadless quick-opening cup lid 20 needs to be tightly closed onto the opening of the cup body 10, this utility model only requires placing the threadless quick-opening cup lid 20 onto the opening of the cup body 10, and then pressing the upper cover 1. The upper cover 1 causes the upper rack guide seat 3 to move with the upper cover 1. The upper rack guide seat 3 and the lower rack guide assembly 4 move relative to each other, compressing and deforming the elastic sealing element 2. After the lower rack guide assembly 4 is fixed on the upper cover 1, it causes the elastic sealing element 2 to deform (open) and be fixed. The elastic sealing element 2 that contacts the O-ring 100 will then form a sealing connection, which is beneficial for tightly closing the threadless quick-opening cup lid 20 onto the opening of the cup body 10; Figure 17 As shown, when it is necessary to remove the threadless quick-opening cup lid 20, simply open the switch assembly 5. The switch assembly 5 will cause the lower rack guide assembly 4 to disengage from the upper cover 1. After the upper rack guide seat 3 and the lower rack guide assembly 4 move relative to each other, the elastic seal 2 will return to its initial state (original state) due to the absence of external pressure. The elastic seal 2 will then disengage from the O-ring 100, which facilitates the removal of the threadless quick-opening cup lid 20.

[0061] All standard parts used in this application can be purchased from the market, and the specific connection methods of each part adopt conventional methods such as springs and rubber rings that are mature in the existing technology, and will not be described in detail here.

[0062] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
