Technical Field

[0001] This divisional application is a divisional application of the original application (application number: 2024117062757, application date: November 26, 2024).

[0002] This invention relates to the field of container sealing technology, specifically to a button locking assembly for a sealing cap and a sealing container. Background Technology

[0003] A sealed container is a type of container with airtight properties, typically used to store food, cosmetics, medicines, stationery, and other items. Most sealed containers on the market use push-button lids for opening and closing.

Some self-locking mechanisms lack reliability and are easily unlocked by accidental external force, thus compromising the seal. Furthermore, some self-locking switches are prone to jamming and may fail to lock after prolonged use and wear.

[0004] Therefore, how to develop a sealing cover button locking component that is simple in structure, easy to assemble, has stable and reliable locking, and is not prone to misunderstanding has become an important issue that needs to be addressed by those skilled in the art. Summary of the Invention

[0007] When button 3 is pressed down, the locking part 63 moves upward relative to the starting notch 623 along one of the guide paths 626. When button 3 is released, spring 61 drives button 3 to reset and guides the locking part 63 to fall to the ending notch 625, thus achieving a self-locking state. When button 3 is pressed again, the locking part 63 disengages from the ending notch 625 and moves to the other side along the guide path 626, thus achieving an unlocked state.

[0008] Preferably, the main body 621 has a labyrinth groove 622 on both sides; the locking part 63 has a locking part 631 symmetrically arranged on both sides, which moves along the labyrinth groove 622 on both sides respectively.

[0009] Preferably, the faceplate 2 forms a first mounting groove 22 in its middle downward for mounting the button 3, and the faceplate 2 extends upward in the middle of the bottom wall of the first mounting groove 22 to form a vertical guide groove 25; a guide ridge 26 protrudes from one inner side of the guide groove 25, and a guide groove 627 is recessed on the main body 621 for the guide ridge 26 to move up and down along it.

[0010] Preferably, the guide groove 25 has multiple supporting ribs 27 protruding outward on its outer groove wall and a transversely extending strip-shaped opening 28 on its groove wall. The locking part 63 overlaps on the supporting ribs 27, and its locking part 631 passes through the strip-shaped opening 28 into the path of the labyrinth groove part 622.

[0011] Preferably, the first mounting groove 22 has a plurality of vertical guide openings 29 on its side wall, and the button 3 has a guide protrusion 31 that is inserted into the vertical guide opening 29 and moves up and down along the vertical guide opening 29.

[0012] Preferably, the bottom wall of the mounting groove 22 is recessed downward to form an annular limiting groove 221, and the spring 61 is mounted on the annular limiting groove 221.

[0013] The second aspect of the present invention provides a sealed container, including a container body 200 and a sealing cover 100; the sealing cover 100 includes: a sealing cover bottom shell 1, a front shell 2 installed above the sealing cover bottom shell 1, a button 3 installed on the front shell 2, and the button locking device described in the first aspect, wherein a sealing ring 4 is installed around the outer periphery of the sealing cover bottom shell 1.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The design of the labyrinth groove structure and locking parts in this case makes the movement path of the locking parts within the labyrinth groove more complex, making it more difficult for the locking parts to be accidentally unlocked in the locked state. This improves the safety and stability of the sealed container using this locking device and helps ensure sealing performance. Simultaneously, the movement path of the locking parts within the labyrinth groove structure is clear and defined, reducing the likelihood of jamming or failure, thus extending the switch's lifespan. Furthermore, the labyrinth groove design increases the contact area and friction between the locking parts and the labyrinth groove structure, making the locked state more stable and less prone to unlocking due to external interference. The locking device in this case consists of a few components, including a button, spring, labyrinth groove structure, and locking parts. Compared to other complex self-locking switch types, it has fewer components and a simpler assembly process. Moreover, due to the fewer components and simpler design, the labyrinth lock self-locking switch has higher assembly efficiency, helping to reduce production costs and improve production efficiency. The labyrinth groove structure is integrated inside the button, effectively utilizing limited space and making the entire sealed container design more compact and efficient. Furthermore, in this solution, the user can drive the locking parts to move in the labyrinth groove structure simply by pressing, thereby achieving locking and unlocking. The operation is simple and straightforward, requiring no complicated steps or skills.

[0016] 2. This design features labyrinthine grooves on both sides, each equipped with a locking mechanism. This design ensures a more secure connection between the locking components and the main body, effectively preventing loosening or detachment due to external forces, thus improving locking stability. Furthermore, the labyrinthine grooves on both sides increase the structural strength of the main body, making it more resistant to external pressure or impact. The supporting ribs serve two purposes: firstly, they support the locking components, preventing them from wobbling and ensuring stability during the locking and unlocking process; secondly, they further enhance the strength of the guide groove, ensuring the overall structural stability and durability. The strip-shaped opening limits the lateral movement space of the locking components, ensuring that the locking parts can move smoothly along the path of the labyrinthine grooves, thereby achieving the locking or unlocking function.

[0025] The following examples further illustrate the features and other related characteristics of the present invention in detail, to facilitate understanding by those skilled in the art:

[0026] Example 1

[0027] This embodiment provides a button locking assembly for a sealing cover, which is assembled onto the faceplate of the sealing cover; as shown Figures 1 to 7 As shown, a sealing cover includes: a sealing cover bottom shell 1, a front shell 2 mounted above the sealing cover bottom shell 1, and a button 3 mounted on the front shell 2. A sealing ring 4 is installed around the outer periphery of the sealing cover bottom shell 1. A double-lever sealing lifting assembly 5 is installed inside the button 3 to drive the sealing cover bottom shell 1 to compress the sealing ring 4. The double-lever sealing lifting assembly 5 includes: a short lever 51 and a long lever 52, which are cross-hinged. Both the short lever 51 and the long lever 52 have barbs 53 at their tails. The sealing cover bottom shell 1 has a locking hole 11 for the barbs 53 to hook into. The outer edge of the sealing ring 4 abuts against the front shell 2. In a specific implementation, the sealing ring 4 is a silicone sealing ring.

[0028] like Figure 1 , Figure 3 , Figure 4 As shown, in a specific implementation, the sealing cover of this case further includes: a button locking assembly 6, which includes: the button 3, a spring 61 for automatically resetting the button 3 after the external force is released, a labyrinth groove structure 62 disposed inside the button 3, and a locking part 63 capable of limited movement along the labyrinth groove path of the labyrinth groove structure 62; the spring 61 is disposed between the button 3 and the face shell 2; the labyrinth groove structure 62 includes: a main body portion 621 protruding downward from the button 3, and a labyrinth groove portion 622 formed on the main body portion 621, the labyrinth groove portion 622 including: a starting notch 623, a mounting protrusion 624 protruding on the main body portion 621, an ending notch 625 formed on the mounting protrusion 624, and a guide path 626 surrounding the mounting protrusion 624 and connecting the starting notch 623 and the ending notch 625;

[0029] When button 3 is pressed down, the locking part 63 moves upward relative to the starting notch 623 along one of the guide paths 626. When button 3 is released, spring 61 drives button 3 to reset and guides the locking part 63 to fall to the ending notch 625, thus achieving a self-locking state. When button 3 is pressed again, the locking part 63 disengages from the ending notch 625 and moves to the other side along the guide path 626, thus achieving an unlocked state.

[0030] As described above, the design of the labyrinth groove structure and locking parts in this case makes the movement path of the locking parts within the labyrinth groove more complex, making it more difficult for the locking parts to be accidentally unlocked in the locked state. This improves the safety and stability of the sealed container using this locking device and helps ensure sealing performance. Simultaneously, the movement path of the locking parts within the labyrinth groove structure is clear and defined, reducing the likelihood of jamming or failure, thus extending the switch's lifespan. Furthermore, the labyrinth groove design increases the contact area and friction between the locking parts and the labyrinth groove structure, making the locked state more stable and less prone to unlocking due to external interference. The locking device in this case consists of a small number of components, including a button, spring, labyrinth groove structure, and locking parts. Compared to other complex self-locking switch types, it has fewer components and a simpler assembly process. Moreover, due to the fewer components and simpler design, the labyrinth lock self-locking switch has higher assembly efficiency, helping to reduce production costs and improve production efficiency. The labyrinth groove structure is integrated inside the button, effectively utilizing limited space and making the entire sealed container design more compact and efficient. Furthermore, in this solution, the user can drive the locking parts to move in the labyrinth groove structure simply by pressing, thereby achieving locking and unlocking. The operation is simple and straightforward, requiring no complicated steps or skills.

[0031] Furthermore, the design of the starting and ending recesses and guide paths in the labyrinth groove creates a complex labyrinth path, significantly increasing the movement complexity of the locking components during locking and unlocking, thereby significantly improving the security of the sealed container using this locking device. The mounting protrusions provide support for the ending recesses and increase the overall structural strength of the labyrinth groove, helping to prevent deformation or damage due to long-term stress during use, thus improving the durability of the locking device. The guide paths are arranged around the mounting protrusions; this layout allows the locking components to be evenly stressed during movement, reducing wear or jamming caused by uneven stress, further improving locking stability.

[0032] like Figure 3 and Figure 4As shown, in a specific implementation, the faceplate 2 extends upward from the middle of the bottom wall of the mounting groove 22 to form a vertical guide groove 25; a guide ridge 26 protrudes from one inner side wall of the guide groove 25, and a guide groove 627 is recessed on the main body 621 to allow the guide ridge 26 to move up and down along it. Thus, the cooperation of the guide ridge and the guide groove provides clear guidance for the up and down movement of the button and its main body, ensuring the stability of the button during pressing and releasing, preventing the button from shifting or shaking during operation, thereby improving the user's operating experience. The design of the guide ridge and the guide groove makes it easier to position the button and its main body during installation, preventing the faceplate and button from being installed backwards, thus preventing mistaken installation, simplifying the installation process, and improving operating efficiency.

[0033] like Figures 3 to 6 As shown, in a specific implementation, the main body 621 has labyrinth grooves 622 on both sides; the locking part 63 has locking parts 631 symmetrically arranged on both sides, which move along the labyrinth grooves 622 respectively; the guide groove 25 has multiple supporting ribs 27 protruding outward on its outer groove wall and has a transversely extending strip-shaped opening 28 on its groove wall. The locking part 63 overlaps the supporting ribs 27, and its locking part 631 passes through the strip-shaped opening 28 into the path of the labyrinth groove 622. In a specific implementation, the locking part 631 passes through the strip-shaped opening 28 and falls into the initial recess of the labyrinth groove when initially installed.

[0034] As described above, the inclusion of labyrinthine grooves on both sides, along with corresponding locking mechanisms, ensures a more secure connection between the locking components and the main body. This effectively prevents the locking components from loosening or falling off due to external forces, thereby improving locking stability. Furthermore, the labyrinthine grooves on both sides increase the structural strength of the main body, making it more resistant to external pressure or impact. The supporting ribs serve two purposes: firstly, they support the locking components, preventing them from wobbling and ensuring stability during the locking and unlocking process; secondly, they further enhance the strength of the guide groove, ensuring the overall structural stability and durability. The strip-shaped opening limits the lateral movement space of the locking components, ensuring that the locking parts can move smoothly along the path of the labyrinthine grooves, thus achieving the locking or unlocking function.

[0035] like Figure 3 and Figure 4 As shown, in a specific implementation, the side wall of the mounting groove 22 is provided with multiple vertical guide openings 29, and the button 3 is provided with a guide protrusion 31 that is inserted into the vertical guide opening 29 and moves up and down along the vertical guide opening 29; the outer periphery of the bottom wall of the first mounting groove 22 is recessed downward to form an annular limiting groove 221, and the spring 61 is installed on the annular limiting groove 221.

[0036] As described above, by creating multiple vertical guide openings on the sidewall of the mounting groove and cooperating with them, a stable guide path can be provided for the button. After the guide protrusion engages with the vertical guide opening, the button's up-and-down movement is restricted by the vertical guide opening, thus preventing the button from shaking or shifting during movement. The annular limiting groove provides a clear mounting position for spring 2, ensuring the stability and accuracy of the spring during installation, preventing the spring from shifting or falling off during installation, thereby improving the reliability and durability of the entire structure. The design of the annular limiting groove also simplifies the installation process of spring 2. Installers can more easily place the spring in the correct position without additional fixing devices or tools, making installation more convenient.

[0037] like Figure 1 , Figure 5 , Figure 6 As shown, the short lever 51 is a double-armed short lever with two arms for support, and the long lever 52 is a double-armed long lever with two arms for support. The short lever 51 has a first shaft 511 protruding inward at both ends of its arms, and the long lever 52 has elongated holes 521 in its arms. The short lever 51 slides into the elongated holes 521 on both sides of the long lever 52 through its first shaft 511. Specifically, the short lever 51 has two symmetrically arranged short support arms, and the long lever 52 has two symmetrically arranged long support arms.

[0038] As described above, by employing a double-armed short lever 51 and a double-armed long lever 52 with double-arm support, the double-armed lever can more effectively distribute pressure and reduce the situation of excessive force at a single point compared to a single-armed lever. On the one hand, this avoids the problem of poor sealing effect caused by uneven force distribution; on the other hand, it can also extend the service life of the sealing cap. Due to the stability of the lever structure and the optimization of force distribution, it helps to ensure a tight contact between the sealing ring and the sealing surface, thereby improving the sealing effect and preventing air, moisture or other contaminants from entering the container. Among them, the short lever 51 is fitted into the elongated holes 521 on both sides of the long lever 52 through its first shaft 511 to achieve a sliding setting, which not only enhances the connection stability between the levers, but also makes the lever movement more flexible.

[0039] like Figure 1 As shown, in a specific implementation, the long lever 52 has a support protrusion 523 near the top of each of its support arms, and the support protrusion 523 forms a V-shaped support angle with the head of each support arm of the long lever 52. The head of each support arm of the long lever 52 is pressed by the button 3 when the button 3 is pressed.

[0040] As described above, the V-shaped support angle design allows the long lever 52 to better distribute pressure when under force, reducing excessive force at a single point and thus enhancing the strength and stability of the entire lever structure. The support protrusion 523 further reinforces the lever's support points, making the lever move more smoothly and reducing the risk of poor sealing due to vibration or shaking. Each support arm head is equipped with a silicone pad 524 to ensure good elasticity and a tight contact between the long lever 52 and the sealing cover bottom shell 1 when the button 3 is pressed. Furthermore, the silicone pad 524 provides cushioning, reducing impact and vibration on the long lever 52 under force, preventing wear from frequent pressing, and extending its service life.

[0041] like Figure 1 , Figure 3 , Figure 4 As shown, the faceplate 2 extends downwards from its bottom wall near the outer periphery to form a ring of top pressure ribs 21, and forms a first mounting groove 22 in its middle for mounting the button 3. A retaining strip 23 protrudes from the outer wall of the first mounting groove 22. The sealing cover bottom shell 1 extends upwards from its middle to form a second mounting groove 12 for the first mounting groove 22 to be inserted into. A retaining groove 13, which engages with the retaining strip 23, is provided on the bottom wall of the inner side of the second mounting groove 12. A retaining hole 11 is located in the second mounting groove 12. In a specific implementation, the sealing cover bottom shell 1 has first reinforcing ribs 14 distributed diffusely around the outer periphery of the second mounting groove 12, and the faceplate 2 has multiple second reinforcing ribs 24 protruding inwards from its top pressure rib 21.

[0042] As described above, the top pressure rib 21 can compress and expand the sealing ring downwards when the button is pressed down, enhancing the sealing effect. The first mounting groove 22 provides an independent mounting area for the button 3. The matching arrangement of the retaining strip 23 and the retaining groove facilitates a stable connection between the front and back shells and makes disassembly and assembly convenient. The second mounting groove 12 provides corresponding placement space for the first mounting groove 22. The first reinforcing rib 14 increases the structural strength of the sealing cover and back shell. The second reinforcing rib 24 increases the structural strength of the front shell and prevents deformation.

[0043] Example 2

[0044] like Figure 8As shown, a sealed container includes a container body 200 and a sealing cap 100 as described in Embodiment 1. In practice, when the user presses down on the button, the long lever moves downwards due to the pressure on the button, and the short lever also moves downwards under the influence of the long lever. The other ends of the two levers tilt upwards. The long and short levers have barbs at their ends to hook onto holes in the bottom shell, causing the bottom shell to move upwards. The pressure ribs on the top shell press against the sealing ring, preventing foreign objects from entering. Furthermore, when the bottom shell 1 of the sealing cap is lifted upwards, the sealing ring interferes with the pressure ribs inside the top shell, causing them to deform and compress the container body to form a seal.

[0045] In summary, the sealing cap includes a bottom shell, a top shell, a button, and a double-lever sealing lifting assembly. The double-lever sealing lifting assembly consists of a short lever and a long lever that are cross-hinged, both with double-arm support structures, enhancing structural stability and force uniformity. The long lever features a V-shaped support angle and a silicone pad, improving sealing effect and durability. The top shell and bottom shell are connected by a locking strip and slot, ensuring a stable structure and easy assembly / disassembly. The sealing cap also includes a button locking assembly, employing a labyrinth groove structure and locking parts, improving safety and stability. The sealing container consists of a container body and a sealing cap, allowing for easy switching between sealed and unsealed states via button operation. This invention features a compact structure, convenient operation, and excellent sealing effect, and has broad application prospects.

[0046] As stated above, this case protects a button locking device for a sealed cover and a sealed container, and all technical solutions that are the same as or similar to this case should be considered to fall within the protection scope of this case.
