Description

The present invention relates to the technical field of sealed containers, and more specifically to a fastening structure for a sealed container cover, a sealed container cover, and a container.

A so-called sealed container is a container that is isolated from the outside and does not leak gas.

The applicant has previously filed a patent application for a sealed container that uses a radially deformable elastic sealing member to seal the container cover and the container. However, when the internal pressure of the sealed container exceeds a critical value for the frictional force between the elastic sealing member and the inner wall of the container, the elastic sealing member is unable to completely seal the container cover and the container, causing the container cover and the container to separate and resulting in gas leakage from the sealed container.

Based on this, it is necessary to provide a fastening structure for a sealed container cover, a sealed container cover, and a container.

A fastening structure for a sealed container cover, comprising at least two fastening assemblies and stoppers that fit into the positions of the fastening assemblies. The fastening assemblies are evenly installed on the connecting member of the sealed container cover. When the fastening assemblies abut against the stoppers during the process of sealing the sealed container cover and the container, at least a portion of them abuts and is held in a predetermined position on the inner layer of the container, causing elastic deformation. When the container cover and the container are released from the seal, the fastening assemblies recover from the deformation and separate from the stoppers.

In one embodiment, the fastening assembly includes a first fastening member and a spring, one end of the spring being fixedly connected to the first fastening member and the other end of the spring being fixedly connected to the connecting member.

In one embodiment, the fastening assembly includes a second fastening member and an elastic rubber block, one end of the elastic rubber block being fixedly connected to the second fastening member and the other end being fixedly connected to the connecting member.

In one embodiment, the fastening assembly includes a third fastening member and an elastic rubber strip, both ends of which are fixed to the connecting member, and at least a portion of which is fixedly or removably connected to the third fastening member.

In one embodiment, the first fastening member has a buckle that abuts against or separates from a limiting portion on the connecting member during the process of abutting or separating the first fastening member from the stopper.

In one embodiment, the third engaging member has a limiting member for controlling the movement of the elastic rubber strip.

In one embodiment, the surface of the stopper adjacent to the fastening assembly has a curved structure.

A sealed container cover with a fastening structure comprises a cover body, a connecting member and a movable base that can move up and down, sequentially disposed below the cover body, an elastic sealing member disposed between the movable base and the connecting member, the elastic sealing member connected to the connecting member or the movable base, an opening/closing mechanism for opening and closing the container cover disposed above the container cover, the fastening assembly evenly disposed on the connecting member, the stopper disposed on the movable base and adapted to the position of the fastening assembly, and the opening/closing mechanism controls the movable base to move toward the connecting member, so that the elastic sealing member seals the container in cooperation with the connecting member and the movable base, and the fastening assembly is compressed so that the stopper moves toward the inner layer of the container until it abuts a predetermined position on the inner layer of the container.

In one embodiment, the opening/closing mechanism includes an opening/closing cover and a sliding cover, which are slidably connected to each other, the opening/closing cover having a stopper member, the sliding cover having a stopper portion, and when the stopper member moves toward or away from the sliding cover to a predetermined position, the stopper portion on the sliding cover abuts against or separates from the stopper member as the sliding cover slides over the opening/closing cover.

A container with a sealed container cover having a fastening structure. When the container cover and container are sealed, the fastening assembly abuts a predetermined position on the inner layer of the container. When the seal between the container cover and container is released, the fastening assembly separates from the predetermined position on the inner layer of the container, and the fastening assembly returns to its initial state.

In the above-mentioned fastening structure for a sealed container cover, the sealed container cover, and the container, the fastening assembly and stopper are installed in conjunction with each other. When the fastening assembly abuts the stopper during the process of sealing the sealed container cover and the container, at least a portion of it abuts and is held in place on the inner layer of the container, causing elastic deformation. During the process of releasing the seal between the container cover and the container, the fastening assembly recovers from deformation and separates from the stopper. This prevents the elastic sealing member from being unable to complete the seal between the container cover and the container when the internal pressure of the container exceeds the critical value of the friction force between the elastic sealing member and the inner wall of the container, thereby ensuring normal use of the sealed container.

As shown in FIG. 3, in one embodiment, the fastening assembly 100 includes a third fastening member 150 and an elastic rubber strip 160, both ends of which are fixed to the connecting member 320, and at least a portion of which is fixedly or removably connected to the third fastening member 150.

In one embodiment, the first fastening member 110 has a buckle 111, which abuts against or separates from a limiting portion 321 on the connecting member 320 during the process of the first fastening member 110 and the stopper 200 coming into or out of contact with each other.

In one embodiment, the third engaging member 150 has a limiting member 151 for controlling the movement of the elastic rubber strip 160.

In one embodiment, the surface of the stopper 200 adjacent to the fastening assembly 100 has a curved structure.

As shown in FIG. 4 , the sealed container cover with a fastening structure includes a cover body 310, a connecting member 320 and a movable base 330 that can move up and down, which are sequentially provided below the cover body 310, an elastic sealing member 340 provided between the movable base 330 and the connecting member 320, and the elastic sealing member 340 connected to the connecting member 320 or the movable base 330, and an opening/closing mechanism 350 for opening and closing the container cover is provided above the container cover 300, the fastening assembly 100 is evenly installed on the connecting member 320, and the stopper 200 is installed on the movable base 330 and is adapted to the position of the fastening assembly 100. The opening/closing mechanism 350 controls the movable base 330 to move toward the connecting member 320, and the elastic sealing member 340 seals the container through the cooperation of the connecting member 320 and the movable base 330, and the stopper 200 compresses the fastening assembly 100 to move toward the inner layer of the container until it abuts a predetermined position on the inner layer of the container.

As shown in FIG. 5, in one embodiment, the opening/closing mechanism 350 includes an opening/closing cover 351 and a sliding cover 352, which are slidably connected to each other. The opening/closing cover 351 has a stopper member 3511, and the sliding cover 352 has a stopper portion 3522. When the stopper member 3511 moves toward or away from the sliding cover 352 to a predetermined position, the stopper portion 3522 on the sliding cover 352 abuts against or separates from the stopper member 3511 as the sliding cover 352 slides on the opening/closing cover 351.

As shown in Figures 6 and 7, in a sealed container cover container having a fastening structure, when the container cover 300 and the container 400 are sealed, the fastening assembly 100 abuts at a predetermined position on the inner layer of the container. When the seal between the container cover 300 and the container 400 is released, the fastening assembly 100 separates from the predetermined position on the inner layer of the container, and the fastening assembly 100 returns to its initial state.

There are at least two fastening assemblies 100, but the number may be three or four. The fastening assemblies 100 are evenly installed on the connecting member 320 of the sealed container cover. "Evenly installed" means that when the fastening assemblies 100 are attached to the connecting member 320, the connecting member 320 may be divided into several equal parts. The stoppers 200 are adapted to the number and positions of the fastening assemblies 100 and may abut or separate from the fastening assemblies 100 from different directions under the action of external force. An annular groove is provided at a predetermined position on the inner layer of the container 400.

Example 1
The fastening assembly 100 includes a first fastening member 110 and a spring, one end of which is fixedly connected to the first fastening member 110 and the other end of which is fixedly connected to a connecting member 320. A first notch 322 is provided on the connecting member 320 at a position corresponding to the first fastening member 110. During the process of sealing the container cover 300 and the container 400, an external force is applied to the stopper 200, which moves the stopper 200 toward the first fastening member 110 until it abuts against the first fastening member 110. At this time, at least a portion of the first fastening member 110 is pushed by the stopper 200 and moves toward the annular groove of the container 400 through the first notch until it abuts against and engages with the annular groove. At this time, the spring is compressed and deformed, and during the process of unsealing the container cover 300 and the container 400, the stopper 200 gradually separates from the first engaging member 110, and the spring recovers from the deformation, driving the first engaging member 110 to return to its initial position.

Furthermore, a spring accommodating groove is provided in the first engaging member 110.

Example 2
In one embodiment, the fastening assembly 100 includes a second fastening member 130 and an elastic rubber block 140, one end of which is fixedly connected to the second fastening member 130 and the other end of which is fixedly connected to the connecting member 320. The second fastening member 130 has at least two spaced-apart second notches 131 formed in a two-step configuration at one end adjacent to the connecting member 320. During the process of sealing the container cover 300 and the container 400, an external force is applied to move the stopper 200 toward the second fastening member 130 until it abuts against the second fastening member 130. At this time, at least a portion of the second fastening member 130 is pushed by the stopper 200 and moves toward the annular groove of the container 400 through the first notches until it abuts against and engages with the annular groove. At this time, the elastic rubber block 140 is compressed and deformed, and the second notch 131 abuts against the connecting member 320. During the process of unsealing the container cover 300 and the container 400, the stopper 200 gradually separates from the second engaging member 130, and the elastic rubber block 140 recovers from the deformation, driving the second engaging member 130 to return to its initial position.

Example 3
In one embodiment, the fastening assembly 100 includes a third fastening member 150 and an elastic rubber strip 160, both ends of which are fixed to the connecting member 320, and at least a portion of the elastic rubber strip 160 is fixedly or removably connected to the third fastening member 150. The third fastening member 150 has a limiting member 151 for controlling the movement of the elastic rubber strip 160. The limiting member 151 may be a groove or a protrusion. The third fastening member 150 has a two-step third notch 152 at one end adjacent to the connecting member 320.

During the process of sealing the container cover 300 and the container 400, an external force causes the stopper 200 to move toward the third fastening member 150 until it abuts against the third fastening member 150. At this time, the stopper 200 is pushed and moves toward the annular groove of the container 400 through the first notch until at least a portion of the third fastening member 150 abuts against and engages with the annular groove. At this time, the elastic rubber strip 160 bends under the force of the restricting member 151, forming an inwardly bent arcuate surface, and the third notch 152 abuts against the connecting member 320. During the process of releasing the seal between the container cover 300 and the container 400, the stopper 200 gradually separates from the third fastening member 150, and the elastic rubber strip 160 returns to its original shape, driving the third fastening member 150 to return to its initial position.

In this way, the fastening assembly 100 and stopper 200 are installed in conjunction with each other in the fastening structure for the sealed container cover, the sealed container cover, and the container. When the fastening assembly 100 contacts the stopper 200 during the process of sealing the sealed container cover 300 and the container 400, at least a portion of it is held in contact with a predetermined position on the inner layer of the container, causing elastic deformation. When the container cover 300 and the container 400 are released from the seal, the fastening assembly 100 recovers from the deformation and separates from the stopper 200. This prevents the elastic sealing member from being unable to complete the seal between the container cover and the container when the internal pressure of the container exceeds the critical value of the friction force between the elastic sealing member and the inner wall of the container, thereby ensuring normal use of the sealed container.

In one embodiment, the first fastening member 110 has a buckle 111 that abuts against or separates from a limiting portion 321 on the connecting member 320 during the process of separating or abutting the first fastening member 110 and the stopper 200. The limiting portion 321 may be a groove or a protrusion. When the spring 120 drives the first fastening member 110 to move toward the opening/closing mechanism 350 during the process of recovering from deformation during the process of releasing the seal between the container cover 300 and the container 400, the buckle 111 abuts against the limiting portion 321 on the connecting member 320, preventing the first fastening member 110 from moving toward the opening/closing mechanism 350. This limits the movement distance of the first fastening member 110, preventing it from moving too far and preventing the next engagement.

In one embodiment, the surface of the stopper 200 that is closest to the fastening assembly 100 has a curved structure to facilitate contact between the stopper 200 and the fastening assembly 100.

In this way, when the stopper 200 approaches the fastening assembly 100, the surface of the stopper 200 that approaches the fastening assembly 100 has a curved structure, and when the stopper 200 abuts against the fastening assembly 100, the fastening assembly 100 can be quickly pushed to move toward the inner layer of the container, which makes this process easy and quick.

A sealed container cover with a fastening structure comprises a cover body 310, a connecting member 320 and a movable base 330 that can move up and down, sequentially disposed below the cover body 310. An elastic sealing member 340 is disposed between the movable base 330 and the connecting member 320, and the elastic sealing member 340 is connected to the connecting member 320 or the movable base 330. An opening/closing mechanism 350 for opening and closing the container cover is disposed above the container cover 300. A fastening assembly 100 is evenly disposed on the connecting member 320, and a stopper 200 is disposed on the movable base 330 and is adapted to the position of the fastening assembly 100. The opening/closing mechanism 350 controls the movable base 330 to move toward the connecting member 320, and the elastic sealing member 340 seals the container through the cooperation of the connecting member 320 and the movable base 330. The stopper 200 compresses the fastening assembly 100, moving toward the inner layer of the container until it abuts a predetermined position on the inner layer of the container.

When sealing the container cover 300 and the container 400, the opening and closing mechanism 350 is rotated, pulling the movable base 330 so that the opening and closing mechanism 350 moves toward the elastic sealing member 340. The elastic sealing member 340 is deformed outward by the cooperative action of the connecting member 320 and the movable base 330 until it becomes larger than the diameter of the sealing point on the container, thereby completing the sealing of the container 400. The fastening assembly 100 is compressed so that it moves toward the inner layer of the container until the stopper 200 on the movable base 330 abuts against a predetermined position on the inner layer of the container, thereby completing the fastening of the container 400.

In one embodiment, to prevent the opening/closing mechanism 350 from being accidentally removed, the opening/closing mechanism 350 includes an opening/closing cover 351 and a sliding cover 352, the opening/closing cover 351 and the sliding cover 352 being slidably connected, the opening/closing cover 351 having a stopper member 3511, the sliding cover 352 having a stopper portion 3522, and when the stopper member 3511 moves toward or away from the sliding cover 352 to a predetermined position, the stopper portion 3522 on the sliding cover 352 abuts against or separates from the stopper member 3511 as the sliding cover 352 slides on the opening/closing cover 351. The opening/closing mechanism 350 and the movable base 330 are detachably connected, and the sliding cover 352 slides on the opening/closing cover 351, thereby increasing the length of the moment arm of the opening/closing cover. If the bottom of the sliding cover 352 is higher than the mounting seat of the movable base 330, the opening/closing mechanism 350 can be easily removed from the movable base 330. By providing a stopper member 3511 on the opening/closing cover 351 and a stopper portion 3522 on the sliding cover 352, when the opening/closing mechanism 350 does not need to be removed, the stopper member 3511 is pushed toward the sliding cover 352 until it reaches a predetermined position. At this time, the sliding cover 352 abuts against the stopper portion 3522 as it slides upward, thereby lowering the bottom of the sliding cover 352 below the mounting seat of the movable base 330, thereby preventing the opening/closing mechanism 350 from being accidentally removed. When the opening/closing mechanism 350 needs to be removed from the movable base 330, the stopper member 3511 is pulled away from the sliding cover 352 until it reaches the predetermined position. At this time, if the slide cover 352 does not come into contact with the stopper portion 3522 when sliding upward, and the position of the bottom of the slide cover 352 is higher than the height of the mounting seat of the movable base 330, the opening/closing mechanism 350 may be removed from the movable base 330.

The technical features of the above embodiments may be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features of the above embodiments are described. However, any combination of these technical features, unless inconsistent, should be considered to be within the scope of the present specification.

The above examples merely illustrate some embodiments of the present invention, and although the descriptions are more specific and detailed, they should not be understood as limiting the patent scope of the invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and all of these fall within the scope of protection of the present invention. Therefore, the patent scope of the present invention should be determined based on the appended claims.
