2. Description of the Related Art As this type of self-heating type container, the one shown in FIG. 5 is known. In FIG. 5, a self-heating type container is a cylindrical body (1) made of a composite material mainly composed of paper, and a metal top cover (2) and a bottom cover (2) fixed to both ends of the cylindrical body (1). 3)
A metal heater (4) having a vertical cross section and a substantially inverted U-shape, which is arranged in the lower part of the cylindrical body (1) and fixed to the cylindrical body (1); ) Is sealed with a water-tight bag (6) and quicklime (7). The top lid (2) is fixed to the cylindrical barrel (1) by tightening. A score line (not shown) is formed on the top lid (2) around the entire periphery thereof, and a portion surrounded by the score line is a removal portion (8). The removal portion (8) Attached to is a pull tab (9). The bottom lid (3) is fixed to the cylindrical body (1) by winding. A pin insertion hole (11) and a gas vent hole (12) are formed in the bottom lid (3), and both holes (11) and (12) are respectively in a sheet-like closing member (1).
It was closed in 3). The size of the lower end opening of the heater (4) is slightly smaller than the size of the lower end opening of the cylindrical body (1), and the flange (4a) formed on the lower end portion of the peripheral wall of the heater (4) together with the bottom lid (3) forms the cylindrical body ( The heater (4) is fixed to the cylindrical body (1) by being wound around the lower end of 1). The bottom lid (3) closes the lower end opening of the heater (4). A sheet-like leakage prevention member (10) for preventing leakage of water (5) and quick lime (7) is arranged so as to cover the upper surface of the bottom lid (3).

The heating of the liquid to be heated (L) such as liquor and coffee sealed inside in such a self-heating type container is performed as shown in FIG. That is, first, the container is turned upside down and the bottom lid (3) is turned to the upper side, and then the closing member (13).
Then, the pin (15) is inserted into the heater (4) through the pin insertion hole (11), and the water (5) is spilled out by breaking through the water-sealed bag (6). After that, pull out the pin (15) and turn the container upside down again. Then, water (5) and quick lime (7) come into contact with each other to cause an exothermic reaction,
This heat is transmitted to the liquid (L) through the wall of the heater (4), and the liquid (L) is heated.

However, the conventional self-heating type container has the following problems. That is, when the pin (15) is inserted into the heater (4) through the pin insertion hole (11) and the water-tight bag (6) is pierced, the container is not turned upside down again, that is, FIG. When left as it is, the liquid (L)
The air existing in the space (S) above is heated and expanded, and this pressure is applied to the cylindrical body (1), so that the cylindrical body (1)
Deforms outward in the circumferential direction (see the chain line in FIG. 6), and the tightening force at the tightening portion is weakened. Also, in severe cases, the tightening can be removed. As a result, the liquid (L) may leak.
