Specific embodiment

The utility model is described in further detail with embodiment for explanation with reference to the accompanying drawing, and the mode of the utility model includes But it is not limited only to following embodiment.

As shown in Figs 1-4, a kind of tin can provided by the utility model, structure is simple, design is scientific and reasonable, user Just, tin can is easy to open, and can also facilitate heating when edible.The utility model includes bottom seal, top opening, simultaneously It and is in the can box main body 1 of hollow cylinder, and match with the can box main body 1 and sealing cover is connected to the can The can ends 2 at 1 top of box main body；The top exterior walls of the can box main body 1 be equipped with external screw thread, the can box main body 1 it is interior Bottom is equipped with the exothermic mixture packet 3 that exothermic reaction can be generated with water, is being located at the exothermic mixture packet 3 just in the can box main body 1 Top is equipped with food packaging cartridge 4.

Can ends 2 described in the utility model include can ends main body 21, and the can ends main body 21 is by inner wall 24 and outside The sealing double-layer structure that wall 25 forms, and the inner cavity air pressure of the double-layer structure is higher than external atmosphere pressure, the can ends main body 21 24 lower part of inner wall is equipped with the internal screw thread 23 matched with the external screw thread, and the can ends main body 21 passes through the internal screw thread 23 Lid is connected to the top of the can box main body 1, and the outer wall 25 of the can ends main body 21 is equipped with for releasing bilayer after pulling open The pressure release pull ring 22 of gas in structure inner chamber, the outer wall 25 of the can ends main body 21 is thicker than inner wall 24, and the can ends Main body 21 squeezes the inner wall 24 by the air pressure of its double-layer structure inner cavity and seals with the can box main body 1, and the pressure release is drawn Ring 22 is located at the outer of the outer wall 25 of the can ends main body 21, and the inner wall 24 and outer wall 25 of the can ends main body 21 are one Body formula structure.

The utility model can ends main body is set as double-layer structure, and the inner cavity air pressure of double-layer structure is higher than external atmosphere pressure, and And inner wall is thinner than outer wall, it therefore, can be by the inner wall of can ends main body and can box main body by the air pressure of double-layer structure inner cavity It compresses, realizes that can ends main body enclosing cover is connected on can box main body, when needing canned food, pressure release pull ring is pulled open, it is double The pressure release of layer structure inner chamber, inner wall lose the pressure of inner cavity, easily can unscrew can ends main body from can box main body very much.

In order to facilitate the unlatching of food packaging cartridge, food packaging cartridge 4 described in the utility model includes that food encapsulates box main body It 41 and food is seal-installed on by double seam encapsulates the food of 41 top opening of box main body and encapsulate box cover 42, food envelope Mounted box lid 42, which is equipped with, tears trace 43 for open the food packaging cartridge 4, and described one end for tearing trace 43 is equipped with and tears Open pull ring 44.

Can box main body 1, the food packaging cartridge 4 and the can ends 2 described in the utility model are made by tinplate It forms, tinplate material is cheap and easy to get, is suitable for large-scale production.

The utility model sets exothermic mixture packet in can box main body, when needing canned food, pressure release pull ring is pulled open, to tank After the double-layer structure inner cavity air pressure venting of head cartridge main body, can ends are unscrewed, proper amount of clear water are injected in can box main body, then immediately Can ends lid is closed on can box main body, the clear water of injection is contacted with exothermic mixture packet makes exothermic mixture contract for fixed output quotas raw exothermic reaction, puts Thermal energy out heats the food packaging cartridge being located at right above exothermic mixture packet, is torn after the completion of to be heated by tearing pull ring What food packaging cartridge covered tears trace, can start to eat, easy to operate, convenient.

Above-described embodiment is only one of preferred embodiments of the present invention, should not be taken to limit the utility model Protection scope, as long as the utility model body design thought and mentally make have no the change of essential meaning or profit Color, it is solved the technical issues of it is still consistent with the utility model, the protection scope of the utility model should all be included in Within.
