[0018] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific implementation manners.

[0019] In the description of the utility model, it should be explained that the orientation or position relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "another end" and the like is the orientation or position relationship shown in the drawing, and is only for the convenience of describing the utility model and simplifying the description, and is not indicative or suggestive of the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicative or suggestive of relative importance.

[0020] In the description of the utility model, it is necessary to explain that, unless there is definite stipulation and limitation, the terms "mount", "set with", "connect" and the like should be understood broadly, for example, "connect", can be fixedly connected, also can be detachably connected, or integrally connected;Can be mechanical connection, also can be electrical connection;Can be directly connected, also can be indirectly connected through intermediate medium, can be the communication inside two elements.For the ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0021] Please refer to Figs. 1-3 The utility model provides a technical scheme:

[0022] A paper can bottle cap structure of high sealing performance, including paper can body 1, paper can body 1 upper end fixedly connected with connecting port 2, and the connecting port 2 upper end is inserted and movably connected with sealing device 3.

[0023] In the embodiment, the sealing device 3 includes a paper cover 31, a plurality of grooves 33 are formed on the outer surface of the paper cover 31, the plurality of grooves 33 are arranged in a ring shape at equal distances, an inner sealing layer 32 is fixedly connected to the inner wall of the paper cover 31, a reinforcing member 35 is fixedly connected to the inner wall of the inner sealing layer 32, the reinforcing member 35 has a cross shape, and a rubber sealing ring 34 is placed between the inner sealing layer 32 and the paper cover 31; a first arc surface 311 is arranged at the lower part of the paper cover 31; a second arc surface 321 is arranged at the lower part of the paper cover 31; the position of the first arc surface 311 corresponds to the position of the second arc surface 321; the inner sealing layer 32 is located inside the connecting port 2; and the paper cover 31 is located on the outer surface of the connecting port 2.

[0024] Through the above scheme: when the paper cover 31 is covered on the paper can body 1, it not only tightly wraps the outer surface of the connecting port 2 to form a preliminary protective barrier, but also the built-in inner sealing layer 32 is tightly attached to the inner wall of the connecting port 2, effectively blocking the penetration of external air, and the rubber sealing ring 34 is placed between the inner sealing layer 32 and the paper cover 31, tightly filling the tiny gap between them, and the tacit cooperation between the inner sealing layer 32, the rubber sealing ring 34 and the paper cover 31 greatly improves the sealing performance of the connecting port 2.
