[0024] 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 being separated or abutted against each other.

[0025] In one embodiment, the third fastening member 150 has a limiting member 151 for controlling the movement of the elastic rubber strip 160 .

[0026] In one embodiment, the surface of the stopper 200 adjacent to the fastener assembly 100 has a curved structure.

[0027] As shown in FIG. 4, a sealed container cover having a fastening structure includes a cover body 310, a connecting member 320 and a movable base 330 movable up and down are sequentially provided under the cover body 310, an elastic sealing member 340 is provided between the movable base 330 and the connecting member 320, 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 provided on the upper side of the container cover 300, the fastening assembly 100 is evenly installed on the connecting member 320, the stopper 200 is installed on the movable base 330 and fits to the position of the fastening assembly 100, and 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.

[0028] As shown in FIG. 5, in one embodiment, 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 are slidably connected, the opening / closing cover 351 has a stopper member 3511, and the sliding cover 352 has a stopper portion 3522, and when the stopper member 3511 moves close to or away from the sliding cover 352 to a predetermined position, during the process of the sliding cover 352 sliding on the opening / closing cover 351, the stopper portion 3522 on the sliding cover 352 abuts against or separates from the stopper member 3511.

[0029] 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, and 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.

[0030] The number of fastening assemblies 100 is at least two, for example, three or four. The fastening assemblies 100 are evenly installed on the connection member 320 of the sealed container cover. The so-called evenly installed means that when the fastening assemblies 100 are attached to the connection member 320, the connection member 320 may be divided into several equal parts. The stopper 200 is adapted to the number and position of the fastening assemblies 100, and may abut or separate from the fastening assemblies 100 from different directions under the action of external force, and a ring-shaped groove is provided at a predetermined position on the inner layer of the container 400.

[0031] 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 the 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, the stopper 200 moves toward the first fastening member 110 under the action of an external force until it abuts against the first fastening member 110. At this time, at least a part of the first fastening member 110 moves toward the annular groove of the container 400 through the first notch by the pushing movement of the stopper 200 until it abuts against and engages with the annular groove. At this time, the spring is compressed and deformed, and in the process of releasing the seal between the container cover 300 and the container 400, the stopper 200 gradually separates from the first fastening member 110, and the spring recovers from the deformation, driving the first fastening member 110 to return to its initial position.

[0032] Furthermore, the first fastening member 110 is provided with a spring receiving groove.

[0033] 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 two-step second notches 131 spaced apart at one end adjacent to the connecting member 320. During the process of sealing the container cover 300 and the container 400, the stopper 200 moves toward the second fastening member 130 under the action of an external force until it abuts against the second fastening member 130. At this time, at least a part of the second fastening member 130 moves toward the annular groove of the container 400 through the first notches due to the pushing of the stopper 200 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 releasing the seal between the container cover 300 and the container 400, the stopper 200 gradually separates from the second fastening member 130, and the elastic rubber block 140 recovers from the deformation, driving the second fastening member 130 to return to its initial position.

[0034] 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.

[0035] During the process of sealing the container cover 300 and the container 400, the stopper 200 moves toward the third fastening member 150 under the action of an external force until it abuts against the third fastening member 150. At this time, at least a part of the third fastening member 150 moves toward the annular groove of the container 400 through the first notch by the pushing of the stopper 200 until it abuts against and engages with the annular groove. At this time, the elastic rubber strip 160 is bent by the force of the restricting member 151 to form an inwardly bent arc surface shape, 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 initial shape, driving the third fastening member 150 to return to its initial position.

[0036] In this way, in the fastening structure of the sealed container cover, the sealed container cover, and the container, the fastening assembly 100 and the stopper 200 are installed in coordination, and during the process of sealing the sealed container cover 300 and the container 400, when the fastening assembly 100 abuts against the stopper 200, at least a portion of it is held in abutment at a predetermined position on the inner layer of the container, causing elastic deformation, and during the process of releasing the seal between the container cover 300 and the container 400, the fastening assembly 100 recovers from the deformation and separates from the stopper 200, thereby avoiding the elastic sealing member 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.

[0037] 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 separating or abutting the first fastening member 110 and the stopper 200. The limiting portion 321 may be a groove or a protrusion. During the process of releasing the seal between the container cover 300 and the container 400, 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, the buckle 111 abuts against the limiting portion 321 on the connecting member 320 to prevent the first fastening member 110 from moving toward the opening / closing mechanism 350, thereby limiting the moving distance of the first fastening member 110 and avoiding the first fastening member 110 moving too far to be able to engage the next time.

[0038] In one embodiment, the surface of the stopper 200 adjacent to the fastener assembly 100 has a curved structure to facilitate contact between the stopper 200 and the fastener assembly 100 .

[0039] In this manner, during the process of the stopper 200 approaching the fastening assembly 100, the surface of the stopper 200 approaching 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 is easy and quick.

[0040] A sealed container cover having a fastening structure, comprising a cover body 310, a connecting member 320 and a movable base 330 movable up and down are sequentially provided under the cover body 310, an elastic sealing member 340 is provided 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 provided on the upper side of the container cover 300, a fastening assembly 100 is evenly provided on the connecting member 320, a stopper 200 is provided on the movable base 330 and fits to the position of the fastening assembly 100, and the opening / closing mechanism 350 controls the movable base 330 to move toward the connecting member 320, so that 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.

[0041] When sealing the container cover 300 and the container 400, the opening and closing mechanism 350 is rotated to pull the movable base 330 so that the opening and closing mechanism 350 moves toward the elastic sealing member 340, and the elastic sealing member 340 is deformed outward until it becomes larger than the diameter of the sealing point of the container through the cooperation of the connecting member 320 and the movable base 330, thereby completing the sealing of the container 400, and 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.

[0042] In one embodiment, in order to prevent the opening / closing mechanism 350 from being erroneously 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 are slidably connected, the opening / closing cover 351 has a stopper member 3511, the sliding cover 352 has a stopper portion 3522, and when the stopper member 3511 moves close to 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 during the process of the sliding cover 352 sliding on the opening / closing cover 351. The opening / closing mechanism 350 and the moving 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. When 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 can be easily removed from the movable base 330. By providing the stopper member 3511 on the opening / closing cover 351 and the stopper portion 3522 on the slide cover 352, when it is not necessary to remove the opening / closing mechanism 350, the stopper member 3511 is pushed so as to move toward the slide cover 352 until it reaches a predetermined position. At this time, the slide cover 352 can be made lower than the height of the mounting seat of the movable base 330 by abutting and holding the stopper portion 3522 when sliding upward, thereby preventing the opening / closing mechanism 350 from being removed by mistake. When it is necessary to remove the opening / closing mechanism 350 from the movable base 330, the stopper member 3511 is pulled so as to move in a direction away from the slide cover 352 until it reaches a predetermined position. At this time, if the slide cover 352 is not held in 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.

[0043] 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, but any combination of these technical features, unless contradictory, should be considered to be within the scope described in this specification.

[0044] The above examples merely describe some embodiments of the present invention, and although the description is more specific and detailed, it should not be understood as limiting the patent scope of the invention. It should be noted that a person skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and all of them belong to the protection scope of the present invention.
