DETAILED DESCRIPTION

[0030] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application. EXAMPLE

[0031] In combination with the drawings shown in Figure 1 , Figure 2 and Figure 10 , the easy-open can lid of the present embodiment includes a fixed cover body 2 mounted at the top opening of an easy-open can 100, a movable bottom cover 8 hinged at the bottom of the fixed cover body 2, an opening 3 provided on the fixed cover body 2, and an opening mechanism 5 provided in the opening 3. The opening mechanism 5 includes a pull ring body 53 and a rotating shaft 52 located on the pull ring body 53; the movable bottom cover 8 is provided with a hinged seat 51 at the upper portion, and the rotating shaft 52 can rotate in the hinged seat 51; when the pull ring body 53 is lifted upward to rotate around the rotating shaft 52, the pull ring body 53 can push the movable bottom cover 8 downward to open the easy-open can; the fixed cover body 2 is provided with a locking mechanism 6 for locking the opening mechanism 5 from turning over.

[0032] The application provides a novel easy-to-pull can lid which is mainly composed of an easy-to-pull lid body 1 and is used for being installed at a top opening of an easy-to-pull can to realize sealing and opening functions. A fixed lid body 2 is a part of the easy-to-pull lid body 1 which is installed at the top opening of the easy-to-pull can and plays a basic fixing role. An opening 3 is formed in the fixed lid body 2, and the opening 3 provides a channel space for the subsequent setting of a pull ring body 53 and the outflow of substances in the can.

[0033] An active bottom cover 8 is hinged to the fixed lid body 2, so that the active bottom cover 8 can rotate at a certain angle relative to the fixed lid body 2. Specifically, the fixed lid body 2 comprises an upper lid body 21 and a lower lid body 22 which are respectively arranged at the upper part and the lower part of the top opening of the can body, the upper lid body 21 and the lower lid body 22 are fixedly connected, the active bottom cover 8 is hinged to the lower lid body 22, a first sealing piece 9 is arranged on the active bottom cover 8, the first sealing piece 9 plays a role in enhancing the sealing performance between the active bottom cover 8 and the fixed lid body 2 when the active bottom cover 8 is closed with the fixed lid body 2, so as to prevent the substances in the can from leaking, and a connecting cover 4 is fixedly arranged at the upper part of the pull ring body 53, the connecting cover 4 and the pull ring body 53 can be regarded as a whole, a through hole 41 is formed in the connecting cover 4, and a fixed column 532 matched with the through hole 41 is arranged on the pull ring body 53. The through hole 41 penetrates through the thickness direction of the connecting cover 4, provides a space for the insertion of the fixed column 532, and fixes the connecting cover 4 and the pull ring body 53 as a whole, the pull ring body 53 is arranged in the opening 3 of the fixed lid body 2, and the shape and size of the pull ring body 53 should be adapted to the opening 3, so that the pull ring body 53 can be installed at the opening 3 and realize the functions of opening and closing the opening 3. That is, the rotation of the pull ring body 53 can be transmitted to the active bottom cover 8, so that the active bottom cover 8 is driven to perform a turnover action, and the opening 3 is opened or closed.

[0034] A locking mechanism 6 is arranged on the fixed lid body 2 and is used for locking the turnover of the pull ring body 53. When the easy-to-pull lid is not needed to be opened, the locking mechanism 6 fixes the pull ring body 53 at the position of closing the opening 3, so as to prevent the pull ring body 53 from being accidentally turned over and causing the substances in the can to leak; when the easy-to-pull lid needs to be opened, the locking mechanism 6 is released from locking the pull ring body 53 through a specific operation, so that the pull ring body 53 can be freely turned over.

[0035] When the easy-to-pull lid is not opened, the active bottom cover 8 keeps a relative fixed position with the fixed lid body 2 through the hinge, and the first sealing piece 9 ensures that the active bottom cover 8 and the fixed lid body 2 are well sealed. At the same time, the locking mechanism 6 locks the pull ring body 53, so that the pull ring body 53 is fixed at the position of closing the opening 3, and the substances in the can are prevented from leaking through the opening 3, at this time, the whole easy-to-pull lid is in a sealed state, and the substances in the can are protected.

[0036] When the pull ring body 53 is rotated by an external force, the pull ring body 53 drives the opening mechanism 5 to act, and in turn drives the connecting part of the movable bottom cover 8 and the fixed cover body 2 to flip, so that the opening 3 is opened, and the substances in the can can flow out through the opening 3.

[0037] If it is needed to close again after opening, the pull ring body 53 is reversely rotated, the pull ring body 53 reversely flips the movable bottom cover 8 through the opening mechanism 5, so that the movable bottom cover 8 re-closes the opening 3, and then the locking mechanism 6 locks the pull ring body 53 again to restore the sealed state.

[0038] In combination with Figures 3-9 As shown in the figure, the opening mechanism 5 includes a hinge seat 51 arranged at the top of the movable bottom cover 8 on both sides, a rotating shaft 52 arranged inside the hinge seat 51, and a pull ring body 53 connected to the rotating shaft 52, and the top of the pull ring body 53 is fixedly connected to the connecting cover 4.

[0039] Specifically, the opening mechanism 5 is a device for realizing the flipping of the pull ring body 53 and in turn controlling the opening and closing of the pull ring can opening, and the hinge seat 51 is arranged at the top of the movable bottom cover 8 on both sides. The two hinge seats 51 provide a basic support and positioning structure for the whole opening mechanism 5, are fixed to the movable bottom cover 8, and ensure the stability of the installation of subsequent components.

[0040] The rotating shaft 52 is installed inside the hinge seat 51. The rotating shaft 52 is a core rotating component of the opening mechanism 5, can freely rotate in the hinge seat 51, provides a rotating shaft for the movement of the whole mechanism, and enables other components connected thereto to rotate around it.

[0041] The pull ring body 53 is connected to the rotating shaft 52. One end of the pull ring body 53 is sleeved on the rotating shaft 52 and can rotate with the rotating shaft 52. The pull ring body 53 plays a force transmission role, and when an external force is applied to the pull ring body 53, the pull ring body 53 rotates around the rotating shaft 52, thereby driving other related components to move.

[0042] In combination with Figure 4 , Figure 7 , Figure 8 and Figure 9As shown, the inside of the hinge seat 51 is provided with an oval-shaped groove 511, and the rotating shaft 52 is inserted into the groove 511 and connected slidingly therein. Specifically, the hinge seat 51 is a base support component of the opening mechanism 5 and is arranged on both sides of the opening 3. The inside of the hinge seat 51 has a key structure, i.e., the oval-shaped or waist-shaped groove 511. The groove 511 provides a mounting and moving space for the rotating shaft 52, so that the pull ring body 53 can rotate and hinge in the groove 511 and also move a certain distance along the length direction of the groove 511. Meanwhile, a corresponding inclined surface 14 is arranged on the upper part of the hinge seat 51 and the lower part of the rotating shaft 52 for easy installation.

[0043] The locking mechanism 6 includes a sliding groove 61 arranged on both sides of the opening 3, and the outer ends of the pull ring body 53 are provided with sliding blocks 531 matched with the sliding groove 61. Specifically, the locking mechanism 6 is a key part of the new type of can body easy-open lid for controlling the overturning of the pull ring body 53 to realize the opening or closing of the can body. The sliding groove 61 is arranged on both sides of the opening 3. The sliding groove 61 is a long strip-shaped structure, which provides a sliding track for the sliding blocks 531 at the outer ends of the pull ring body 53 and is an important space limiting component for realizing the function of the locking mechanism 6.

[0044] The sliding blocks 531 are arranged on both sides of the outer ends of the pull ring body 53. The shape and size of the sliding blocks 531 are matched with the sliding groove 61, so that the sliding blocks 531 can smoothly slide in the sliding groove 61. The sliding blocks 531 are fixedly connected with the pull ring body 53 and drive the pull ring body 53 and the connecting cover 4 connected therewith to perform corresponding actions through the sliding of the sliding blocks 531, so that the sliding blocks 531 are key components for transmitting motion in the locking mechanism 6.

[0045] In the normal closed state of the easy-open can, the sliding blocks 531 at the outer ends of the pull ring body 53 are located at specific positions of the sliding groove 61, which are generally close to the inside of the can body and limit the upward overturning of the pull ring body 53. At this time, the pull ring body 53 cannot rotate upward around the rotating shaft 52 due to the blocking of the sliding blocks 531 by the structure of the sliding groove 61, and the connecting cover 4 fixedly connected with the top of the pull ring body 53 also cannot overturn, thereby tightly closing the opening 3 and effectively preventing the leakage of the contents in the can.

[0046] When the easy-open can needs to be opened, an operator holds the pull ring body 53 with his hand and applies a pulling force in a specific direction. Under the action of the pulling force, the sliding blocks 531 begin to slide in the sliding groove 61. With the continuous action of the pulling force, the sliding blocks 531 move along the track of the sliding groove 61 and gradually move away from the locking position, generally when the sliding blocks 531 appear in the field of view. When the sliding blocks 531 slide to a position in the sliding groove 61 that allows the pull ring body 53 to overturn upward, the pull ring body 53 can rotate and overturn upward around the rotating shaft 52.

[0047] One end of the sliding groove 61 is provided with an outlet 611 for the sliding block 531 to enter and exit. Specifically, the outlet 611 is provided at one end of the sliding groove 61 and is designed specifically for the sliding block 531 to enter and exit the sliding groove 61. The size of the outlet 611 is adapted to the sliding block 531 to ensure that the sliding block 531 can pass through smoothly, and at the same time, it will not be too large to cause the sliding block 531 to accidentally fall out under non-operating conditions. When the can is in the normal closed state of unopened, the sliding block 531 is located at the end of the sliding groove 61 away from the outlet 611. At this time, the inner wall of the sliding groove 61 restricts the movement of the sliding block 531, thereby preventing the pull ring body 53 from rotating upward around the rotating shaft 52.

[0048] When the contents of the can are used up or the can needs to be temporarily closed, the operator presses the connecting cover 4 downward. The connecting cover 4 drives the pull ring body 53 to rotate downward, and at the same time, the sliding block 531 moves towards the direction of the sliding groove 61. When the sliding block 531 reaches the outlet 611 again, continued pressing will make the sliding block 531 enter the sliding groove 61 through the outlet 611 and slide along the sliding groove 61 to the initial locking position away from the outlet 611. At this time, the pull ring body 53 is again restricted from being flipped upward, and the connecting cover 4 also tightly seals the opening 3, and the can returns to the locked state.

[0049] Regarding the sealing of the can body easy open lid, as shown in Figure 11 The upper part of the movable bottom cover 8 is provided with a first sealing member 9 for sealing between the movable bottom cover 8 and the lower cover body 22. The first sealing member 9 is annular and made of soft rubber or silicone; The lower cover body 22 is provided with a second sealing member 10 for sealing between the lower cover body 22 and the lower part of the opening at the top of the can. The second sealing member 10 is annular and made of soft rubber or silicone.

[0050] The movable bottom cover 8 is provided with a third sealing member 11 in the middle, and the pull ring body 53 is provided with a sealing boss 12 corresponding to the third sealing member 11. The third sealing member is provided with a gas hole 13 in the center. In the closed state of the easy open lid, the sealing boss 12 abuts against the third sealing member 11 to block the gas hole 13. Generally, the can is filled with carbonated beverages, and the inside is under a certain degree of high pressure. The movable bottom cover 8 is also in a state of being pressed tightly on the can body. In order to push it down, it needs to be depressurized in advance. When the pull ring body 53 moves horizontally outward, even during the process of the sliding block 531 moving away from the locking position, the sealing boss 12 is not in abutment with the third sealing member 11, so that the gas hole 13 is exposed and depressurized, and then it can be normally opened. Embodiment
