[0028] When in use, the mouth first contacts the upper flange structure. Compared to the existing technology where the external thread is directly set on the can opening structure, the upper flange structure 5 of this utility model ensures that the mouth contacts the upper flange structure 5 when drinking beverages. The upper flange structure 5 is as follows: Figure 3The longitudinal section of the neck structure 1 is circular, which makes the mouth more comfortable and enhances the drinking experience, and the lower end of the neck structure 1 is connected with a ring-shaped limiting plate 6, and the outer ring of the ring-shaped limiting plate 6 is connected with a downward turning edge structure 7, the ring-shaped limiting plate 6 cooperates with the downward turning edge structure 7 to increase the contact area between the top cover and the can body, thereby improving the sealing degree between the can body and the top cover, and in order to further improve the relative sealing of the top of the can body and the top cover, the inner ring of the downward turning edge structure 7 is provided with a ring-shaped rubber strip 9, and the top of the can body is generally installed by pressing, and the top of the can body is partially clamped into the downward turning edge structure 7, and the ring-shaped rubber strip 9 is squeezed, thereby greatly improving the sealing performance, and the inner ring of the ring-shaped limiting plate 6 is provided with a sunken groove 8, and the groove bottom is lower than the lower surface of the ring-shaped limiting plate 6, which is also used to further increase the contact area between the can body and the top cover, thereby improving the sealing performance after installation, and after the top of the can body is pressed and installed, the top surface is attached to the bottom surface of the ring-shaped limiting plate 6, the outer ring is inserted into the downward turning edge structure 7 and presses the ring-shaped rubber strip 9, and the inner ring is attached to the outer groove wall of the sunken groove 8, and the longitudinal section of the top of the can body is in the shape of 7, and the sunken groove 8 can also be used to hold part of the small water droplets or the part of the beverage that leaks out when drinking, so that the small part of the beverage does not directly flow to the hand from the mouth.

[0029] Embodiment 2:

[0030] In addition to including the structural features of the foregoing embodiments, in the specific embodiments of the utility model, a ring-shaped protrusion 10 that cooperates with the upward turning edge structure 5 is arranged on the inner bottom of the cover groove of the screw cover 3, and the side surface of the ring-shaped protrusion 10 that faces the upward turning edge structure 5 is arranged in an arc shape.

[0031] In order to improve the sealing performance between the screw cover 3 and the top cover, a ring-shaped protrusion 10 that cooperates with the upward turning edge structure 5 is arranged on the inner bottom of the cover groove of the screw cover 3, which can be obviously seen from Figure 1 The ring-shaped protrusion 10 on the inner bottom of the cover groove of the screw cover 3 will be in contact with the outer ring of the upward turning edge structure 5 after the screw cover 3 is installed on the top of the top cover through the internal thread on the inner wall of the cover groove, the side surface of the ring-shaped protrusion 10 that faces the upward turning edge structure 5 is arranged in an arc shape, which is used to further increase the contact area between the two, thereby improving the sealing performance.

[0032] Embodiment 3:

[0033] In addition to comprising the structural features of the preceding embodiments, in the specific embodiments of the utility model, the jar mouth structure 2 is provided with a circular seal 11 at the bottle mouth, the upper surface of the circular seal 11 is provided with a U-shaped pull ring 12, and the two ends of the U-shaped pull ring are connected to the circular seal 11. In the specific embodiments of the utility model, the circular seal 11 is divided into two layers, the upper layer is a hard layer 111, and the lower layer is a plastic layer 112, and the two ends of the U-shaped pull ring 12 are connected to the upper surface of the hard layer 111. In the specific embodiments of the utility model, the distance from the connection of the two ends of the U-shaped pull ring to the center of the hard layer 111 is equal, and the two connections are axially symmetrical.

[0034] The circular seal 11 at the bottle mouth of the jar mouth structure 2 is used after the screw cap 3 is opened, and is used when the beverage in the jar body is not drunk at one time, which facilitates the semi-sealed use of the beverage. At the same time, the circular seal 11 can be used to further improve the sealing of the top of the top cover after the jar is produced. The upper surface of the circular seal 11 is provided with a U-shaped pull ring 12, the two ends of the U-shaped pull ring 12 are connected to the circular seal 11, and in use, the U-shaped pull ring 12 is pulled to separate one side of the circular seal 11 from the bottle mouth of the jar mouth structure 2. The edge of the circular seal 11 is usually bonded to the bottle mouth of the jar mouth structure 2 by means of glue. Half or more of the circular seal 11 is pulled apart, and after one or more sips of beverage are drunk, the part of the circular seal 11 that is pulled apart is pushed back into the bottle mouth of the jar mouth structure 2. This can greatly reduce the entry of external air into the jar body, and can greatly delay the drinkable time regardless of whether the jar body contains beverage or wine. The circular seal 11 is divided into two layers, the upper layer is a hard layer 111, and the lower layer is a plastic layer 112. The material of the plastic layer 112 is used to improve the service life of the circular seal 11. After all, the jar body contains beverage or wine. Plastic can better play the role of sealing and not being easily corroded. The distance from the connection of the two ends of the U-shaped pull ring to the center of the hard layer 111 is equal, and the two connections are axially symmetrical, which is used to improve the connection stability between the U-shaped pull ring and the hard layer 111. When the U-shaped pull ring is pulled, the stress on the hard layer 111 is uniform.

[0035] Embodiment 4:

[0036] In addition to comprising the structural features of the preceding embodiments, in the specific embodiments of the utility model, a connecting part 4 is further arranged between the neck structure 1 and the jar mouth structure 2, the connecting part 4 is a hollow structure and communicates with the neck structure 1 and the jar mouth structure 2. In the specific embodiments of the utility model, the wall thickness of the connecting part 4 is greater than the wall thickness of the jar mouth structure 2 and the neck structure 1, respectively.

[0037] The connection part 4 is arranged to play a role of connecting up and down, and its thickness is greater than the wall thickness of the neck structure 1 and the can mouth structure 2 respectively, so as to increase the strength of the top cover itself, and further play a role of strengthening the connecting strength of the neck structure 1 and the can mouth structure 2.
