[0015] Preferably, sealant is filled between the curling portion and the flanging portion;

[0016] The effect of preventing the sealing from leaking can be achieved by injecting the sealant therebetween.

[0017] Preferably, the inner liner and the curled edge portion and the flange portion on the bottom side thereof are sealed together with the can body by a double-sealing process.

[0018] The utility model provides an inner tank structure for a closed heating tank, which has the following beneficial effects:
