Description

Technical Field

[0001] This invention relates to the technical field of sealed containers, specifically to a fastening structure for a sealed container lid, a sealed container lid, and a container. Background Technology

[0002] A sealed container is a container that is isolated from the outside world and does not leak air.

[0003] The applicant previously applied for a sealing container that uses a radially deformable elastic seal to seal the container lid to the container. However, in the aforementioned sealing container, if the internal pressure exceeds the critical value of the frictional force between the elastic seal and the inner wall of the container, the elastic seal cannot complete the seal between the container lid and the container, causing the container lid to separate from the container and resulting in air leakage from the sealed container. Summary of the Invention

[0004] Therefore, it is necessary to provide a fastening structure for a sealing container lid, a sealing container lid, and a container.

[0005] A fastening structure for a sealed container lid includes at least two fastening components and a stop block adapted to the position of the fastening components. The fastening components are evenly disposed on the connector of the sealed container lid. During the sealing process between the sealed container lid and the container, when the fastening components abut against the stop block, at least part of them abut against a preset position of the inner layer of the container and undergo elastic deformation. During the unsealing process between the container lid and the container, the fastening components restore their deformation and separate from the stop block.

[0006] In one embodiment, the fastening assembly includes a first snap-fit ​​member and a spring, one end of the spring being fixedly connected to the first snap-fit ​​member and the other end being fixedly connected to a connector.

[0007] In one embodiment, the fastening assembly includes a second snap-fit ​​member and an elastic block, one end of which is fixedly connected to the second snap-fit ​​member and the other end of which is fixedly connected to the connector.

[0008] In one embodiment, the fastening assembly includes a third snap-fit ​​member and an elastic strip, both ends of which are fixed to the connector, and at least a portion of the elastic strip is fixedly or detachably connected to the third snap-fit ​​member.

[0009] In one embodiment, the first snap-fit ​​member has a buckle, which abuts or separates from the limiting portion on the connector during the process of the first snap-fit ​​member separating from or abutting the stop block.

[0010] In one embodiment, the third snap-fit ​​member has a limiting member for controlling the movement of the elastic strip.

[0011] In one embodiment, the side of the stop block near the fastening assembly has a curved surface structure.

[0012] A sealing container lid with a fastening structure includes a lid body. A connector and a movable base that can move up and down are sequentially arranged on the lower side of the lid body. An elastic sealing element is provided between the movable base and the connector. The elastic sealing element is connected to the connector or the movable base. An opening and closing mechanism for opening and closing the container lid is provided on the upper side. Fastening components are evenly distributed on the connector. A stop block is arranged on the movable base and is adapted to the position of the fastening components. When the opening and closing mechanism controls the movable base to move towards the connector, the elastic sealing element seals the container under the joint action of the connector and the movable base. At the same time, the stop block compresses the fastening components and moves them towards the inner layer of the container until they abut against a preset position of the inner layer of the container.

[0013] In one embodiment, the opening and closing mechanism includes a switch cover and a sliding cover, which are slidably connected. The switch cover has a stop member, and the sliding cover has a stop portion. When the stop member approaches or moves away from the sliding cover and moves to a preset position, the stop portion on the sliding cover abuts against or separates from the stop member during the sliding process of the sliding cover on the switch cover.

[0014] A container with a sealing lid having a fastening structure, wherein when the lid is sealed to the container, the fastening component abuts against a preset position on the inner layer of the container; when the lid is unsealed from the container, the fastening component separates from the preset position on the inner layer of the container, and the fastening component returns to its initial state.

[0015] The aforementioned fastening structure of the sealed container lid, the sealed container lid, and the container, through the fastening components and their cooperation with the stop block, ensure that during the sealing process between the sealed container lid and the container, the fastening components, when in contact with the stop block, at least partially abut against a preset position on the inner layer of the container and undergo elastic deformation. During the process of releasing the seal between the container lid and the container, the fastening components restore their deformation and separate from the stop block. This prevents the elastic seal from failing to seal the container lid and the container when the pressure inside the container exceeds the critical value of the frictional force between the elastic seal and the inner wall of the container, thus ensuring the normal use of the sealed container.

[0023] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediary component present. Conversely, when a component is said to be "directly" connected to another component, there is no intermediary component.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1 As shown, a fastening structure for a sealed container lid includes at least two fastening components 100 and a stop 200 adapted to the position of the fastening components 100. The fastening components 100 are evenly distributed on the connector 320 of the sealed container lid. During the sealing process between the sealed container lid 300 and the container 400, when the fastening components 100 abut against the stop 200, at least partially abut against a preset position of the inner layer of the container 400 and undergo elastic deformation. During the unsealing process between the container lid 300 and the container 400, the fastening components 100 restore their deformation and separate from the stop 200.

[0027] like Figure 1As shown, in one embodiment, the fastening assembly 100 includes a first snap-fit ​​member 110 and a spring, one end of which is fixedly connected to the first snap-fit ​​member 110 and the other end of which is fixedly connected to the connector 320.

[0028] like Figure 2 As shown, in one embodiment, the fastening assembly 100 includes a second snap-fit ​​member 130 and an elastic block 140, one end of the elastic block 140 being fixedly connected to the second snap-fit ​​member 130 and the other end being fixedly connected to the connector 320.

[0029] like Figure 3 As shown, in one embodiment, the fastening assembly 100 includes a third snap-fit ​​member 150 and an elastic strip 160, both ends of which are fixed to the connector 320, and at least a portion of the elastic strip 160 is fixedly or detachably connected to the third snap-fit ​​member 150.

[0030] In one embodiment, the first snap-fit ​​member 110 has a buckle 111, which abuts or separates from the limiting portion 321 on the connector 320 during the process of the first snap-fit ​​member 110 separating from or abutting the stop block 200.

[0031] In one embodiment, the third snap-fit ​​member 150 has a limiting member 151 for controlling the movement of the elastic strip 160.

[0032] In one embodiment, the side of the stop 200 near the fastening assembly 100 has a curved structure.

[0033] like Figure 4 As shown, a sealing container lid with a fastening structure includes a lid body 310. A connector 320 and a movable base 330 that can move up and down are sequentially arranged on the lower side of the lid body 310. An elastic sealing element 340 is provided between the movable base 330 and the connector 320. The elastic sealing element 340 is connected to either the connector 320 or the movable base 330. An opening and closing mechanism 350 for opening and closing the container lid is provided on the upper side of the lid. Fastening components 100 are evenly distributed on the connector 320. A stop block 200 is disposed on the movable base 330 and adapted to the position of the fastening components 100. When the opening and closing mechanism 350 controls the movable base 330 to move towards the connector 320, the elastic sealing element 340 seals the container under the combined action of the connector 320 and the movable base 330. Simultaneously, the stop block 200 compresses the fastening components 100, moving them towards the inner layer of the container until they abut against a preset position on the inner layer of the container.

[0034] like Figure 5As shown, in one embodiment, the opening and closing mechanism 350 includes a switch cover 351 and a sliding cover 352, which are slidably connected. The switch cover 351 has a stop member 3511, and the sliding cover 352 has a stop portion 3522. When the stop member 3511 approaches or moves away from the sliding cover 352 and moves to a preset position, during the sliding process of the sliding cover 352 on the switch cover 351, the stop portion 3522 on the sliding cover 352 abuts against or separates from the stop member 3511.

[0035] like Figure 6 , Figure 7 As shown, a container with a sealing lid having a fastening structure, when the container lid 300 and the container 400 are sealed, the fastening component 100 abuts against a preset position on the inner layer of the container; when the container lid 300 and the container 400 are unsealed, the fastening component 100 separates from the preset position on the inner layer of the container, and the fastening component 100 returns to its initial state.

[0036] There are at least two fastening components 100, for example, there can be three or four. The fastening components 100 are evenly distributed on the connector 320 of the sealed container lid. "Evenly distributed" means that when the fastening components 100 are installed on the connector 320, the connector 320 can be divided into several equal parts. The number and position of the stop blocks 200 are adapted to the fastening components 100, and they can abut or separate from the fastening components 100 from different directions under external force. A pre-set annular groove is provided at a predetermined position on the inner layer of the container 400.

[0037] Example 1:

[0038] The fastening assembly 100 includes a first latching member 110 and a spring. One end of the spring is fixedly connected to the first latching member 110, and the other end is fixedly connected to the connector 320. A first notch 322 is provided on the connector 320 at a position corresponding to the first latching member 110. During the sealing process between the container cap 300 and the container 400, under the action of external force, the stop block 200 moves towards the first latching member 110 until it abuts against the first latching member 110. At this time, at least a portion of the first latching member 110 moves through the first notch towards the annular groove of the container 400 under the push of the stop block 200 until it abuts against the annular groove and is latched in the annular groove. At this time, the spring is compressed and deformed. During the unsealing process between the container cap 300 and the container 400, the stop block 200 and the first latching member 110 gradually separate, the spring recovers its deformation, and drives the first latching member 110 back to its initial position.

[0039] Furthermore, the first snap-fit ​​component 110 is provided with a spring receiving groove.

[0040] Example 2:

[0041] In one embodiment, the fastening assembly 100 includes a second snap-fit ​​member 130 and an elastic block 140, one end of which is fixedly connected to the second snap-fit ​​member 130 and the other end of which is fixedly connected to the connector 320. The second snap-fit ​​member 130 has at least two spaced-apart step-shaped second notches 131 near the connector 320. During the sealing process between the container lid 300 and the container 400, under the action of external force, the stop block 200 moves towards the second latching member 130 until it abuts against the second latching member 130. At this time, at least a portion of the second latching member 130 moves through the first notch towards the annular groove of the container 400 under the push of the stop block 200 until it abuts against the annular groove and is latched in the annular groove. At this time, the elastic rubber block 140 is compressed and deformed, and the second notch 131 abuts against the connector 320. During the process of unsealing between the container lid 300 and the container 400, the stop block 200 and the second latching member 130 gradually separate, the elastic rubber block 140 recovers its deformation and drives the second latching member 130 back to its initial position.

[0042] Example 3:

[0043] In one embodiment, the fastening assembly 100 includes a third snap-fit ​​member 150 and an elastic strip 160. Both ends of the elastic strip 160 are fixed to the connector 320, and at least a portion of the elastic strip 160 is fixedly or detachably connected to the third snap-fit ​​member 150. The third snap-fit ​​member 150 has a limiting member 151 for controlling the movement of the elastic strip 160. The limiting member 151 can be a groove or a protrusion. The end of the third snap-fit ​​member 150 near the connector 320 has a second-stepped third notch 152.

[0044] During the sealing process between the container lid 300 and the container 400, under the action of external force, the stop block 200 moves towards the third latching member 150 until it abuts against the third latching member 150. At this time, at least a portion of the third latching member 150 moves through the first notch towards the annular groove of the container 400 under the push of the stop block 200 until it abuts against the annular groove and is latched in the annular groove. At this time, the elastic rubber strip 160 bends under the force of the limiting member 151, forming an inwardly bent arc shape, and the third notch 152 abuts against the connector 320. During the process of unsealing between the container lid 300 and the container 400, the stop block 200 and the third latching member 150 gradually separate, the elastic rubber strip 160 returns to its initial shape and drives the third latching member 150 back to its initial position.

[0045] In this way, the fastening structure of the sealed container lid, the sealed container lid, and the container are configured through the fastening component 100 and the cooperation with the stop block 200. During the sealing process between the sealed container lid 300 and the container 400, when the fastening component 100 abuts against the stop block 200, it at least partially abuts against the inner layer of the container at a preset position and undergoes elastic deformation. During the process of releasing the seal between the container lid 300 and the container 400, the fastening component 100 returns to its deformation and separates from the stop block 200. This avoids the situation where the elastic seal cannot complete the sealing between the container lid and the container when the pressure inside the container exceeds the critical value of the frictional force between the elastic seal and the inner wall of the container, thus ensuring the normal use of the sealed container.

[0046] In one embodiment, the first latching member 110 has a latch 111. During the process of the first latching member 110 separating from or abutting the stop block 200, the latch 111 abuts against or separates from the limiting part 321 on the connecting member 320. The limiting part 321 can be a groove or a protrusion. During the process of the container cap 300 and the container 400 being unsealed, when the spring 120 moves the first latching member 110 towards the opening and closing mechanism 350 during the process of restoring its deformation, the latch 111 abuts against the limiting part 321 on the connecting member 320, so that the first latching member 110 no longer moves towards the opening and closing mechanism 350, thus limiting the movement distance of the first latching member 110 and preventing the first latching member 110 from moving too far, which would prevent the next latching from being performed.

[0047] In one embodiment, to facilitate the contact between the stop 200 and the fastening component 100, the side of the stop 200 near the fastening component 100 is a curved structure.

[0048] In this way, as the stop 200 approaches the fastening component 100, the side of the stop 200 that approaches the fastening component 100 has a curved structure. When the stop 200 comes into contact with the fastening component 100, it can quickly push the fastening component 100 to move in the direction of the inner layer of the container, which is simple and fast.

[0049] A sealing container lid with a fastening structure includes a lid body 310. A connector 320 and a movable base 330 that can move up and down are sequentially arranged on the lower side of the lid body 310. An elastic sealing element 340 is provided between the movable base 330 and the connector 320. The elastic sealing element 340 is connected to the connector 320 or the movable base 330. An opening and closing mechanism 350 for opening and closing the container lid is provided on the upper side of the container lid 300. Fastening components 100 are evenly arranged on the connector 320. A stop block 200 is arranged on the movable base 330 and is adapted to the position of the fastening components 100. When the opening and closing mechanism 350 controls the movable base 330 to move towards the connector 320, the elastic sealing element 340 seals the container under the joint action of the connector 320 and the movable base 330. At the same time, the stop block 200 compresses the fastening components 100 and moves them towards the inner layer of the container until they abut against a preset position of the inner layer of the container.

[0050] When the container lid 300 and the container 400 are sealed, the opening and closing mechanism 350 is rotated. The opening and closing mechanism 350 pulls the movable base 330 to move towards the elastic sealing member 340. Under the combined action of the connector 320 and the movable base 330, the elastic sealing member 340 deforms outward to a diameter greater than that of the container sealing point, thus completing the sealing of the container 400. The stop block 200 on the movable base 330 compresses the fastening assembly 100 and moves it towards the inner layer of the container until it abuts against the preset position of the inner layer of the container, thus completing the fastening of the container 400.

[0051] In one embodiment, to avoid accidental disassembly of the opening and closing mechanism 350, the opening and closing mechanism 350 includes a switch cover 351 and a sliding cover 352, which are slidably connected. The switch cover 351 has a stop 3511, and the sliding cover 352 has a stop portion 3522. When the stop 3511 approaches or moves away from the sliding cover 352 and moves to a preset position, during the sliding process of the sliding cover 352 on the switch cover 351, the stop portion 3522 on the sliding cover 352 abuts against or separates from the stop 3511. The opening and closing mechanism 350 is detachably connected to the movable base 330, and the sliding cover 352 can slide on the switch cover 351 to increase the lever arm length of the switch cover. When the bottom position of the sliding cover 352 is higher than the height of the mounting base of the movable base 330, the opening and closing mechanism 350 can be easily detached from the movable base 330. By using the stop 3511 on the switch cover 351 and the stop 3522 on the sliding cover 352, when it is not necessary to disassemble the opening and closing mechanism 350, the stop 3511 is pushed towards the sliding cover 352 until it reaches a preset position. At this time, the sliding cover 352 can resist the stop 3522 when it slides upward, so that the bottom of the sliding cover 352 is lower than the height of the mounting base of the movable base 330, thus preventing the opening and closing mechanism 350 from being accidentally disassembled. When it is necessary to remove the opening and closing mechanism 350 from the movable base 330, the stop 3511 is pulled away from the sliding cover 352 until it reaches a preset position. At this time, the sliding cover 352 does not resist the stop 3522 when it slides upward. When the bottom of the sliding cover 352 is higher than the height of the mounting base of the movable base 330, the opening and closing mechanism 350 can be removed from the movable base 330.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
