Example 1

As shown in fig. 1 and 2, a pop can opening sealing structure comprises an inner concave column groove 101 at the top of a pop can, wherein a main shaft 1 is arranged at the center of the inner concave column groove 101, a rotary sealing cover 2 is rotatably arranged on the main shaft 1, and the rotary sealing cover 2 can cover a pop can opening 100; at least two groups of magnetic components 3 are arranged on the side wall of the inner concave column groove 101, each magnetic component 3 comprises a first magnetic part 31 arranged at the near end of the pop can opening 100 and a second magnetic part 32 arranged at the far end of the pop can, and the magnetic components 3 can be connected with the rotary sealing cover 2 in a suction manner. The rotary sealing cover 2 can freely rotate in the inner groove column at the top of the pop can, when a user drinks liquid in the pop can, the rotary sealing cover 2 can be rotated to one side far away from the opening of the pop can and is fixedly attracted by the second magnetic part 32, when the user does not drink the liquid in the pop can in a short time, the rotary sealing cover 2 can be rotated to the position above the opening of the pop can, the second magnetic part 32 is fixedly attracted by the rotary sealing cover 2, the rotary sealing cover 2 is ensured to seal the opening of the pop can so as to ensure that the liquid in the pop can cannot be spilled, and the liquid in the pop can is prevented from being polluted by external impurities.

An operation groove 21 is arranged on one side of the top of the rotary sealing cover 2 far away from the main shaft 1. The main shaft 1 is sleeved with a bearing 11, and the rotary sealing cover 2 is sleeved outside the bearing 11. The operating groove 21 is convenient for angular adjustment by rotating the closure 2 by finger drive, thereby realizing rapid closure and opening of the can opening. The rotary sealing cover 2 can freely rotate on the main shaft 1 through the bearing 11, and the sealing cover failure caused by the fact that the rotary sealing cover 2 and the main shaft 1 cannot smoothly rotate due to overlarge friction resistance is avoided.

First magnetism spare 31 and second magnetism spare 32 use main shaft 1 to set up as the axis symmetry, first magnetism spare 31 includes two magnetic sheets 311 that set up in the zip-top can mouth both sides, the inner wall of interior concave column groove 101 is connected in the laminating of magnetic sheet 311.

The first magnetic part 31 is used for fixing the rotary sealing cover 2 when the rotary sealing cover 2 is at the position for closing the opening of the pop can, and the second magnetic part 32 is used for fixing the rotary sealing cover 2 when the rotary sealing cover 2 is at the position for opening the opening of the pop can. The thin wall of the magnetic sheet 311 will not affect the rotation of the rotary cover 2 when the rotary cover 2 is closed.

The rotary sealing cover 2 is arranged between the ring-pull can pull ring 103 and the top surface of the ring-pull can, and the bottom of the rotary sealing cover 2 is attached to the top surface of the ring-pull can. The rotary closure 2 is provided with a chamfer 4 near the edge of the can tab 103. The rotary sealing cover 2 can be attached to the top surface of the pop can, and the design can ensure that when the rotary sealing cover 2 is positioned at the position for closing the opening of the pop can, the gap between the rotary sealing cover 2 and the opening of the pop can is effectively eliminated, and the sealing performance is improved. As shown in fig. 5, since the rotary sealing cap 2 is located at the bottom of the can tab 103, the chamfer 4 structure of the rotary sealing cap 2 can prevent the contact area between the rotary sealing cap and the can tab 103 from being too small when the rotary sealing cap is away from the can opening, and prevent the ring tab from being easily bent due to stress concentration when the ring tab is stressed.

The rotary cover 2 is made of stainless steel. The rotary sealing cover 2 is exposed at the top of the pop can and made of stainless steel materials, so that the influence on the overall appearance attractiveness of the pop can caused by rusting in the transportation process can be effectively avoided.

Particularly, the thickness of the middle part of the rotary sealing cover 2 is larger than that of the edge, so that the rotary sealing cover 2 can be smoothly inserted between the pull ring 103 of the pop can and the top surface of the pop can in the rotating process.

The utility model discloses in, after the easy open can was produced, the acquiescence position of rotatory closing cap 2 was in easy open can mouth top, and this can avoid in the transportation impurity to fall to on the apron 102 of easy open can mouth department to apron 102 immerses jar interior liquid and produces the pollution when the easy open can is opened. As shown in fig. 3 and 4, when a user opens a pop can, the rotary sealing cap 2 is firstly rotated to the bottom of the pop can pull ring 103, and the thickness of the edge of the rotary sealing cap 2 is thinner, so that the rotary sealing cap 2 can be smoothly inserted into the bottom of the pop can pull ring 103 to realize rotation, and the joint of the pop can pull ring 103 and the top of the pop can is lower than the thickness of the middle part of the rotary sealing cap 2, so that the pulling hole end 104 of the pop can pull ring 103 can be slightly tilted by being supported by the thickness of the rotary sealing cap 2, so that an opening gap 5 exists between the pulling hole end 104 and the top of the pop can, and meanwhile, the highest point of the pull ring cannot exceed the height of the edge of the concave column groove 101, so that the pop can opening caused by mistaken hanging of the pull ring in the transportation process is avoided, and meanwhile, the opening gap 5 can assist the shorter user to quickly pull the pop can open the pop can when the user opens the pop can. When the user does not drink the liquid in the can, the user can rotate the rotary sealing cover 2 to the position above the can opening, the rotary sealing cover 2 is fixedly attracted by the two magnetic sheets 311 of the first magnetic piece 31, and the rotary sealing cover 2 is attached to the can opening, so that the can opening is ensured to be sealed. When drinking again, only the rotary sealing cover 2 needs to be rotated again, so that the second magnetic part 32 attracts and fixes the rotary sealing cover 2, and a user can drink by opening the pop can opening again.

In addition to the above embodiments, the technical features of the present invention can be re-selected and combined within the scope of the present invention as disclosed in the claims and the specification to constitute new embodiments, which can be realized by those skilled in the art without any creative work, therefore, the embodiments of the present invention not described in detail should be regarded as specific embodiments of the present invention and within the protection scope of the present invention.
