When the container is produced, the heating bag is only required to be filled into the cavity between the first piston and the second piston, and the liquid which is matched with the heating bag to carry out exothermic reaction is filled into the cavity between the second piston and the end face of the heating bin far away from the opening;

when the application is used, the first piston is pushed, so that the first piston drives the first piston rod to move, and the first piston rod drives the second piston to move, so that the sealing gasket arranged on the second piston is separated from the first bulge loop; because the diameter of the second piston is smaller than the inner diameter of the heating bin and larger than the inner diameter of the first bulge loop, when the sealing gasket on the second piston is tightly attached to the first bulge loop, liquid can be prevented from entering the cavity between the first piston and the second piston, and the problem of heating in advance is caused; after the sealing gasket arranged on the second piston is separated from the first bulge loop, liquid can enter a cavity between the first piston and the second piston from a gap between the second piston and the inner wall of the heating bin, so that the liquid can perform exothermic reaction with the heating bag; the beverage inside the container is heated.

And the limiting device is used for preventing the first piston from being separated from the heating bin when the heating bin is not in use, and the first piston pushes the second piston to move under the action of external force, so that the sealing gasket on the second piston is separated from the first bulge loop, and the problem of heating in advance is caused.

Further, the limiting device comprises a first protruding portion arranged on the inner wall of the heating bin and a recessed portion arranged on the first piston and matched with the first protruding portion.
