Description

Technical Field

[0001] This utility model relates to the field of storage container technology, and in particular to a sealed container. Background Technology

[0002] In daily life, airtight containers are widely used as an important type of container. Their main function is to store various items and ensure that the items are not affected by external environmental factors during storage, thus maintaining their original quality and performance.

[0003] Currently, there are many types of sealed containers on the market, each with its own unique sealing structure. Traditional sealed containers mostly use a simple threaded sealing method, where the lid and body are connected by a threaded connection, relying on the tight fit between the threads and possibly a sealing gasket to achieve a seal. However, the threads are prone to wear during repeated tightening and loosening, leading to a gradual decrease in sealing performance.

[0004] Some sealed containers use a snap-fit ​​sealing structure, where snaps on the lid engage with corresponding grooves on the edge of the container to achieve a connection and seal between the lid and the container. However, this structure requires snaps and grooves in multiple locations on both the lid and the container, making the opening and closing of the lid less convenient and impacting usability. Utility Model Content

[0005] The purpose of this invention is to provide a sealing container that can ensure the stability of sealing performance and improve the convenience of use.

[0006] To achieve the above objectives, the solution of this utility model is: a sealed container, including a container body and a container lid for sealing the container body, the container lid including: an outer lid body, an inner lid body, an elastic sealing ring, a limiting member, a transmission shaft, and a toggle member;

[0008] The actuating element is used to swing and abut against the top surface of the outer cover, and drives the inner cover and the elastic sealing ring to move upward through the drive shaft, so that the elastic sealing ring expands outward to block the gap between the outer cover and the inner wall of the tank to achieve the sealing of the tank cover and the tank body.

[0009] In a preferred embodiment, there are two drive shafts, two through holes, and two pivot joints. The limiting member is U-shaped and has a concave part and a convex part. The two convex parts of the limiting member are located in the two through holes, and the concave part of the limiting member abuts against the top surface of the outer cover. The top ends of the two drive shafts pass through the through holes and are hooked onto the limiting member. The two pivot joints are respectively pivotally connected to the top ends of the two drive shafts. The top end of each drive shaft is located between the pivot joint of the actuating member and the limiting member.

[0010] In a preferred embodiment, the bottom end face of the pivot is provided with a limiting protrusion, which is misaligned with the pivot axis.

[0011] In a preferred embodiment, the limiting protrusion is semi-circular.

[0012] In a preferred embodiment, the top surface of the outer cover is provided with a groove, the groove having an open end and a closed end, the open end extending to the edge of the outer cover, a through hole being formed on the bottom surface of the groove near the closed end, a limiting block being movably disposed in the groove near the closed end, a toggle member being disposed in the groove, one end of the toggle member being close to the closed end and pivotally connected to the top of the transmission shaft, and the other end of the toggle member being located at the open end.

[0013] In a preferred embodiment, both the bottom surface of the groove and the actuating component are square, the bottom surface of the groove is provided with a positioning boss, and the actuating component is provided with a positioning through hole at the position corresponding to the positioning boss.

[0014] In a preferred embodiment, the bottom surface of the groove has a recessed portion at the open end of the outer cover edge.

[0015] In a preferred embodiment, the inner cover is provided with an annular groove, the lower part of the elastic sealing ring is engaged in the annular groove, and the upper part of the elastic sealing ring is inclined outward toward the outer cover.

[0016] In a preferred embodiment, the bottom of the outer cover extends towards the inner cover to form an upper limit ring, and the outer wall of the upper limit ring abuts against the inner wall of the upper part of the elastic sealing ring.

[0017] In a preferred embodiment, the inner cover includes a bottom plate and a lower limiting ring formed by the edge of the bottom plate extending towards the outer cover. An annular groove is disposed on the lower limiting ring, the size of the lower limiting ring matches the size of the upper limiting ring, and when the lower limiting ring moves closer to the upper limiting ring, the outer wall of the lower limiting ring abuts against the inner wall of the upper limiting ring.

[0018] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0019] This invention uses a toggle mechanism that swings against the top surface of the outer cover. The drive shaft then moves the inner cover and the elastic sealing ring upwards, causing the elastic sealing ring to expand outwards. This effectively seals the gap between the outer cover and the inner wall of the tank. The operation is simple and convenient. Furthermore, because the limiting component is movably positioned on the top surface of the outer cover, and the top of the drive shaft passes through the through hole in the outer cover and is attached to the limiting component, the inner cover can be effectively prevented from falling into the tank when the toggle mechanism disengages from the drive shaft. This makes the design more user-friendly. Attached Figure Description

[0036] 2. Tank body. Detailed Implementation

[0037] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0038] This embodiment provides a sealed container, such as Figures 1 to 8 As shown, it includes a tank body 2 and a can lid 1 for sealing the tank body 2. The can lid 1 includes: an outer lid body 11, an inner lid body 12, an elastic sealing ring 13, a limiting member 14, a drive shaft 15, and a toggle member 16.

[0039] The outer cover 11 has a through hole 112. The inner cover 12 is located below the outer cover 11 and moves in the direction of approaching or away from the outer cover 11. The elastic sealing ring 13 is located on the inner cover 12. The limiting member 14 is movably located on the top surface of the outer cover 11. The bottom end of the drive shaft 15 is located on the top surface of the inner cover 12. The top end of the drive shaft 15 passes through the through hole 112 of the outer cover 11 and is hooked on the limiting member 14. The actuating member 16 is located on the top surface of the outer cover 11 and has a pivot part 161. The pivot part 161 is pivotally connected to the top end of the drive shaft 15. The vertical distance between the bottom end face of the pivot part 161 and its pivot axis is less than the vertical distance between the top of the pivot part 161 and the side of the outer cover 11 that it abuts and its pivot axis.

[0040] The actuating element 16 is used to swing and abut against the top surface of the outer cover 11 and drive the inner cover 12 and the elastic sealing ring 13 to move upward through the transmission shaft 15, so that the elastic sealing ring 13 expands outward to block the gap between the outer cover 11 and the inner wall of the tank 2 to achieve the sealing of the tank cover 1 and the tank 2.

[0041] Since the inner cover 12 needs to move up and down below the outer cover 11 to seal, if the top of the drive shaft 15 of the inner cover 12 is simply passed through the through hole 112 of the outer cover 11 and pivotally connected to the actuating member 16, the inner cover 12 will fall into the can 2 when the actuating member 16 is disengaged from the drive shaft 15, affecting the items stored in the can 2.

[0042] Therefore, to avoid such situations, this embodiment movably provides a limiting member 14 on the top surface of the outer cover 11. The top end of the drive shaft 15 passes through the through hole 112 of the outer cover 11 and is hooked onto the limiting member 14. The pivot part 161 of the actuating member 16 is pivotally connected to the top end of the drive shaft 15. That is, the top end of the drive shaft 15 adopts a double pivot connection. When the actuating member 16 is disengaged from the pivot point of the drive shaft 15, it can effectively prevent the inner cover 12 from falling into the can 2, making the design more user-friendly. In addition, when the can lid 1 is unsealed from the can 2, the actuating member 16 is in an upright open state. At this time, the limiting block located at the top end of the drive shaft 15 can also serve a decorative purpose.

[0043] By rotating the actuating component 16 to a horizontal position against the top surface of the outer cover 11, or rotating it to an upright position, the inner cover 12 and the elastic sealing ring 13 can be moved up and down via the drive shaft 15. This causes the elastic sealing ring 13 to expand outward to seal the gap between the outer cover 11 and the inner wall of the can 2, or to retract from the gap between the outer cover 11 and the inner wall of the can 2, thus achieving sealing and locking or unlocking of the can lid 1 and the can 2. The operation is simple and convenient. When the sealed can is used to store items such as fruits and vegetables that require soaking in water and where solids and liquids coexist, it can effectively preserve freshness and prevent leakage, making it convenient for carrying when traveling.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, there are two drive shafts 15, two through holes 112, and two pivots 161, but it is not limited to this. The limiting member 14 is U-shaped and has a concave portion 141 and a convex portion 142. The two convex portions 142 of the limiting member 14 are located in the two through holes 112. The concave portion 141 of the limiting member 14 abuts against the top surface of the outer cover 11. The top ends of the two drive shafts 15 pass through the through holes 112 and are hooked onto the limiting member 14. The two pivots 161 are respectively pivotally connected to the top ends of the two drive shafts 15. The top end of each drive shaft 15 is located between the pivot 161 of the actuating member 16 and the limiting member 14, which can ensure the stability of the inner cover 12 moving up and down and ensure the sealing performance.

[0045] like Figure 4 and Figure 8 As shown, in this embodiment, the bottom end face of the pivot 161 is provided with a limiting protrusion 162. The limiting protrusion 162 is misaligned with the pivot axis, that is, the limiting protrusion 162 is not on the extension line of the length direction of the actuating member 16. Since the vertical distance X between the bottom end face of the pivot 161 and its pivot axis is less than the vertical distance Y between the side of the pivot 161 and its pivot axis, and there is a height difference between the limiting protrusion 162 and the bottom end face of the pivot 161, the actuating member 16 will naturally tilt when it swings to the upright state. The actuating member 16 and the top surface of the outer cover 11 are not in a perpendicular state. The limiting protrusion 162 can play a limiting role, so that the can cover 1 and the can body 2 always remain in a sealed and unlocked state.

[0046] like Figure 3 and Figure 4 As shown, the limiting protrusion 162 in this embodiment is semi-circular, but not limited to this, which makes the swinging process of the toggle member 16 smoother and the operation simpler.

[0047] like Figure 1 and Figure 2 As shown, the top surface of the outer cover 11 in this embodiment is provided with a groove 111. The groove 111 has an open end and a closed end. The open end extends to the edge of the outer cover 11. A through hole 112 is opened on the bottom surface of the groove 111 near the closed end. A limiting block is movably disposed in the groove 111 near the closed end. A toggle member 16 is disposed in the groove 111. One end of the toggle member 16 is close to the closed end and pivotally connected to the top end of the transmission shaft 15. The other end of the toggle member 16 is located at the open end.

[0048] In this embodiment, the toggle 16 is placed in the groove 111, which can avoid accidental contact during use and affect the sealing effect. The open end of the groove 111 extends to the edge of the outer cover 11, making it convenient for the user to rotate the toggle 16, and the operation is simple.

[0049] like Figure 2 As shown, the bottom surface of the groove 111 and the actuating member 16 in this embodiment are both square. The bottom surface of the groove 111 is provided with a positioning boss 113, and the actuating member 16 is provided with a positioning through hole 163 at the position corresponding to the positioning boss 113.

[0050] In this embodiment, the positioning boss 113, in conjunction with the positioning through hole 163, can limit the position of the actuating member 16 in the groove 111, ensuring the stability of the sealing effect.

[0051] like Figure 1 and Figure 2 As shown, in this embodiment, the bottom surface of the groove 111 is provided with a recessed portion 114 at the open end of the edge of the outer cover 11. The recessed portion 114 and the toggle member 16 form a finger placement space, which makes it convenient for the user to rotate the toggle member 16. The structure is simple.

[0052] like Figure 2 and Figure 3 As shown, the inner cover 12 of this embodiment is provided with an annular groove 123, the lower part of the elastic sealing ring 13 is engaged in the annular groove 123, and the upper part of the elastic sealing ring 13 is inclined outward towards the outer cover 11.

[0053] In this embodiment, both the tank body 2 and the tank lid 1 are rounded rectangles. Correspondingly, the annular groove 123 and the elastic sealing ring 13 are also rounded rectangles. The upper part of the elastic sealing ring 13 is inclined outward towards the outer cover 11. When the actuating member 16 swings and abuts against the top surface of the outer cover 11 and drives the inner cover 12 and the elastic sealing ring 13 upward through the transmission shaft 15, the upper part of the elastic sealing ring 13 expands outward to seal the gap between the outer cover 11 and the inner wall of the tank body 2, thereby achieving a seal. The structure is simple and easy to process. Of course, in other embodiments, the rounded rectangle can also be set as a circle.

[0054] like Figure 6 and Figure 8 As shown, since the inner cover 12 moves up and down below the outer cover 11 to achieve sealing, the bottom of the outer cover 11 in this embodiment extends towards the inner cover 12 to form an upper limit ring 115. When the actuating member 16 swings and abuts against the top surface of the outer cover 11 and drives the inner cover 12 and the elastic sealing ring 13 to move upward through the transmission shaft 15, the outer wall of the upper limit ring 115 abuts against the inner wall of the upper part of the elastic sealing ring 13. At the same time, the upper part of the elastic sealing ring 13 expands outward to block the gap between the outer cover 11 and the inner wall of the tank 2, thereby achieving sealing. The structure is simple.

[0055] like Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, the inner cover 12 of this embodiment includes a bottom plate 121 and a lower limiting ring 122 formed by the edge of the bottom plate 121 extending toward the outer cover 11. An annular groove 123 is disposed on the lower limiting ring 122. The size of the lower limiting ring 122 matches the size of the upper limiting ring 115. When the lower limiting ring 122 moves closer to the upper limiting ring 115, the outer wall of the lower limiting ring 122 abuts against the inner wall of the upper limiting ring 115.

[0056] When the actuating element 16 swings and abuts against the top surface of the outer cover 11 and drives the inner cover 12 and the elastic sealing ring 13 to move upward through the transmission shaft 15, the outer wall of the upper limit ring 115 abuts against the inner wall of the upper part of the elastic sealing ring 13, the lower limit ring 122 is embedded in the upper limit ring 115, and the outer wall of the lower limit ring 122 abuts against the inner wall of the upper limit ring 115. At the same time, the upper part of the elastic sealing ring 13 expands outward to block the gap between the outer cover 11 and the inner wall of the tank 2, thereby achieving a seal. The structure is simple.

[0057] The working process of this embodiment is as follows:

[0058] like Figure 6As shown, when the seal is locked, the pivoting member 16 is rotated to a horizontal position against the top surface of the outer cover 11. The transmission shaft 15 drives the inner cover 12 and the elastic sealing ring 13 to move upward, and the elastic sealing ring 13 expands outward to seal the gap between the outer cover 11 and the inner wall of the tank 2. Because the vertical distance between the bottom end face of the pivot 161 and its pivot axis is less than the vertical distance between the side face of the pivot 161 and its pivot axis, the can cover 1 and the tank 2 are always kept in a sealed and unlocked state.

[0059] like Figure 8 As shown, during the sealing and unlocking process, by rotating the actuating element 16 to an upright position, the transmission shaft 15 drives the inner cover 12 and the elastic sealing ring 13 to move downwards, and the elastic sealing ring 13 exits from the gap between the outer cover 11 and the inner wall of the can 2. Since the vertical distance between the bottom end face of the pivot 161 and its pivot axis is less than the vertical distance between the side of the pivot 161 and its pivot axis, and there is a height difference between the limiting protrusion 162 and the bottom end face of the pivot 161, the actuating element 16 will naturally tilt when it is rotated to an upright position, so that the can cover 1 and the can 2 always remain in a sealed and unlocked state.

[0060] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0061] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
