fig. 3 is a bottom view of fig. 2.

Reference numerals:

1 can body, 11 pull rings, 2 sealing films, 20 sealing cavities, 3 heat sealing layers, 31 positioning ring grooves, 4 aluminum foil layers, 41 handheld parts, 5PE layers and 6 ethylene-vinyl acetate copolymer layers.

Detailed Description

As shown in fig. 1, fig. 2 and fig. 3, a can comprises a can body 1 and a tab 11 disposed on the can body 1, and comprises a sealing film 2, wherein the sealing film 2 comprises a heat-sealing layer 3 and an aluminum foil layer 4, the heat-sealing layer 3 comprises a PE layer 5 and an ethylene-vinyl acetate copolymer layer 6, the aluminum foil layer 4 is disposed on the PE layer 5, a positioning ring groove 31 is further disposed on the heat-sealing layer 3, the sealing film 2 passes through the heat-sealing layer 3 and then is bonded on the can body 1, and a sealing cavity 20 for sealing the tab 11 is formed between the sealing film 2 and the can body 1.

The sealing film 2 is arranged on the tank body 1, so that the pull ring 11 on the tank body 1 is sealed in the sealing cavity 20 formed by the sealing film 2 and the tank body 1, the pull ring 11 can isolate various foreign matters in the air, a consumer can drink more confidently, secondly, the sealing film 2 is positioned on the tank body 1 through the positioning ring groove 31, not only can the sealing film 2 be quickly installed and positioned, but also the sealing film 2 can move in the radial direction of the tank body 1, the fixing quality and the sealing effect of the sealing film 2 are improved, the sealing film 2 is prevented from falling off in the transportation process, so that the protection effect on a tank opening is improved, finally, the heat sealing layer 3 is arranged into the PE layer 5 and the ethylene-vinyl acetate copolymer layer 6, and the heat sealing layer 3 has good performance of a viscous metal due to the ethylene-vinyl acetate copolymer, is easy to be opened, so that the consumer can have better experience, the consumption experience is increased, the sealing film 2 after being uncovered can be used as a raw material for secondary utilization, can be conveniently disposed, and is strong in environmental protection.
