Liquefied butane gas is usefully used that much, but careful attention must be paid in order to use liquefied butane gas vulnerable to heat and pressure it is easily expanded by heat and has a danger of a possible explosion. The most dangerous accident when the portable gas stove is used is an explosion accident attributable to the overheating of a disposable gas can in which flammable liquefied butane gas is filled in the nature of liquefied butane gas as described above. Accordingly, special attention must be paid because the explosion force of liquefied butane gas expanded by heat corresponds to an explosion which may kill or injure people around 10 m or more. One of the causes of the generation of most accidents attributable to the explosion of the disposable gas can may include the use of an excessive hot grill. If a hot grill or a frying pan is placed higher than the top of a gas can reception unit in which the disposable gas can is received, the upper side of the disposable gas can is overheated by heat from the excessive hot grill or the heat is transferred to the disposable gas can through a boundary surface on the burner unit side of a housing and the gas can reception unit. Accordingly, there is a problem in that an accident in which the gas can explodes because pressure within the gas can is increased due to the overheating of the gas can.
