[0028] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used only for explaining the utility model and cannot be understood as limiting the utility model.

[0029] The embodiments of the utility model will be described below according to the overall structure of the utility model.

[0030] An improved easy -open can cover, likeFigure 1 Figure 4 As shown, it comprises a cover 1, a sealing cover plate 6 and a drinking opening 10.

[0031] Specifically, the cover 1 is rotatably installed with a rotating shaft seat, and the rotating shaft seat is installed with a pull tab 3, and the end of the pull tab 3 is installed with a pressing plate 31 for extruding the sealing cover plate 6. The pressure transmission capability of the pressing plate 31 converts the movement of the pull tab 3 into extrusion force on the sealing cover plate 6, making it easier to open the sealing cover plate 6. The coverage area of the pull tab 3 is larger than the area of the drinking opening 10, which is used to shield the drinking opening 10, so as to completely shield the drinking opening 10 when the pull tab 3 is in the closed position, preventing foreign matter from entering the tank. The bottom surface of the pull tab 3 is installed with a sealing gasket 32 corresponding to the drinking opening 10, and the area of the sealing gasket 32 is larger than the drinking opening 10, which is used to further seal the drinking opening 10, so that the pull tab 3 produces a tighter sealing effect on the drinking opening 10. The top of the cover 1 is installed with a limiting frame 7 on one side of the drinking opening 10, which is used to limit the position of the pull tab 3, thereby preventing the pull tab 3 from deviating during rotation. The limiting frame 7 guides the pull tab 3 during rotation, ensuring that the pull tab 3 can smoothly seal the drinking opening 10. Through the guidance of the limiting frame 7, the pull tab 3 can be more accurately aligned with the drinking opening 10, while ensuring that the sealing gasket 32 can tightly fit the edge of the drinking opening 10 when closed, thereby improving the sealing performance.

[0032] Please refer to Figure 1 Figure 4 The top of the cover 1 is provided with a groove 2 corresponding to the pull tab 3, and the bottom surface of the groove 2 is lower than the plane where the bottom surface of the pull tab 3 is located, which is used for the user to pull the pull tab 3 upwards. Through the design of the groove 2, it is easier to apply tension to the pull tab 3, and the convenience of operation is improved.

[0033] Please refer to Figure 1 Figure 4 The end of the pressing plate 31 is located above the sealing cover plate 6, so that when tension is applied to the pull tab 3, the pressing plate 31 can be driven to rotate, thereby allowing the pressing plate 31 to extrude the sealing cover plate 6. The top of the cover 1 is provided with an installation slot 11 corresponding to the pressing plate 31, so that the pressing plate 31 can be placed in the position of the installation slot 11 when extruding the sealing cover plate 6, thereby more easily separating the sealing cover plate 6 and the cover 1. The drinking opening 10 and the installation slot 11 are communicated.

[0034] Please refer to Figure 1 Figure 4 ​​​​The rotating shaft base comprises a rotating base 5 rotatably connected with the cover body 1, and the rotating base 5 is rotated to make the pull-tab 3 above the drinking opening 10, so that the pull-tab 3 completely covers the drinking opening 10, thereby avoiding foreign matters from entering the drink through the drinking opening 10, and the rotating base 5 is provided with a bearing seat 4 rotatably connected with the pull-tab 3, so that the pull-tab 3 can be kept stable during rotation.

[0035] Please refer to Figure 1 - Figure 4 The rotating base 5 is provided with an opening corresponding to the position of the mounting groove 11, so that the pressing plate 31 is arranged at the position of the mounting groove 11 when the pull-tab 3 is pulled to open the sealing cover plate 6, and the length of the opening is less than the radius of the rotating base 5, so that the rotating base 5 can seal the mounting groove 11 after the pull-tab 3 is rotated and the drinking opening 10 is sealed, thereby enhancing the sealing performance.

[0036] Please refer to Figure 1 - Figure 4 The limiting frame 7 is designed as an arc-shaped block corresponding to the outer wall of the pull-tab 3, the movement range of the pull-tab 3 is limited by the limiting frame 7, so that the pull-tab 3 can smoothly enter the limiting frame 7 to cover the drinking opening 10, thereby improving the sealing performance of the pull-tab 3 on the drinking opening 10, and the position of the limiting frame 7 is staggered with the pressing plate 31, so as to ensure that the pressing plate 31 does not affect the limiting frame 7 during rotation, thereby keeping the smooth operation of the pull-tab 3.

[0037] Please refer to Figure 1 - Figure 4 The bottom of the limiting frame 7 is provided with a slot 71 abutting the outer wall of the pull-tab 3, so that the pull-tab 3 is kept close and stable after entering the slot 71, and the edge of the opening position of the slot 71 is designed as an inclined angle, so as to guide the pull-tab 3 to smoothly enter the slot 71 by chamfering the opening position of the slot 71, thereby further improving the sealing performance of the pull-tab 3 on the drinking opening 10.

[0038] The working principle of the utility model is as follows: in the use process, the user first needs to pull the pull-tab 3 upwards from the position of the groove 2, so that the pull-tab 3 drives the pressing plate 31 to rotate, the pressing plate 31 extrudes the sealing cover plate 6, the sealing cover plate 6 is separated from the cover body 1, and the drinking opening 10 is forced to be opened, so that the easy-open can is more easily opened;

[0039] In use, if it is desired to reseal the can, a downward force is applied to the pull-tab 3, causing it to rotate to the starting position under the restraint of the bearing seat 4, and the pull-tab 3 is then pushed clockwise, causing it to rotate via the rotating base 5, and the edge of the pull-tab 3 is pushed into the limiting frame 7, in the process, as the pull-tab 3 gradually approaches the limiting frame 7, the outer wall of the pull-tab 3 will come into contact with the slot 71, at which point the inclined surface of the slot 71 will guide the pull-tab 3, ensuring that the pull-tab 3 can smoothly enter the slot 71, when the outer wall of the pull-tab 3 abuts the inner wall of the slot 71, at which point the pull-tab 3 completely covers the drinking opening 10, and the rotating base 5 covers the mounting slot 11, thereby achieving the purpose of completely sealing the drinking opening 10, preventing subsequent foreign matter from entering the can, in the rotation process of the pull-tab 3, as the pull-tab 3 enters the slot 71, the sealing gasket 32 gradually enters the drinking opening 10, when the pull-tab 3 completely enters the slot 71, the top and bottom surfaces of the pull-tab 3 abut the inner wall of the slot 71 and the top surface of the cover 1 respectively, and because the area of the sealing gasket 32 is greater than the drinking opening 10, the sealing gasket 32 will be subjected to the pressure exerted by the opening of the drinking opening 10 and the pull-tab 3, causing the sealing gasket 32 to deform, further enhancing the sealing effect of the drinking opening 10, so that after the can is not finished in one go, the drinking opening 10 can be resealed, avoiding direct contact between the beverage and the air, and problems such as oxidation and deterioration.

[0040] Although the embodiments of the present application have been shown and described, the specific embodiments are merely illustrative of the present application, and are not intended to limit the present application, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and those skilled in the art can make modifications, replacements and variations of the embodiments without creative contribution after reading the present specification, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
