DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 and 2. Reference numeral 1 denotes an oil receiving tray 3 provided in an oil combustion apparatus 2 such as a vertically long known oil stove or oil fan heater. The cartridge type tank main body is placed upside down and supplies fuel oil, and a cylindrical oil injection port 4 is projectingly opened on the upper surface.

A screw is formed on the side surface of the oil filling port 4, and a lid 5 that is screwed into the screw is provided. A valve device (not shown) is provided at the tip of the lid 5, and fuel is supplied to the oil receiving tray 3 via the valve device when the tank is set in the oil receiving tray 3. A fulcrum 7 around which the handle 6 rotates is provided at the same position on the front surface and the back surface of the side surface of the tank body 1. The fulcrum 7 is formed by a hole provided at the center of a hollow mounting member 8 attached to the tank body 1 by spot welding or the like, and is formed on the side surface on the left side of the perpendicular line (the one-dot chain line in FIG. 1) passing through the center of gravity of the tank body 1. Therefore, it is provided at the same position on the front surface and the back surface.

The handle 6 is rotated about a fulcrum 7, and a wire rod having a diameter of about 4 mm is appropriately bent and the tip is hooked on the fulcrum 5. The handle 6 is covered with a resin tube or cushion material. A grip portion 9 is provided. The dimension L1 of the handle 6 is longer than half the height dimension L2 of the tank main body 1 so that the tank main body 1 can be used in both the upright state and the inverted state.

An upper stopper 10 is provided above the fulcrums of the front surface and the rear surface of the tank body 1, and is formed so as to project from the tank body 1 so as to prevent the handle 6 from rotating upward. Reference numeral 11 denotes a lower stopper provided on the front surface and the rear surface of the tank body 1 below the fulcrum 7, so as to prevent the tank body 1 from rotating when carrying the tank body 1 upside down. It is provided so as to project more. In this embodiment, the stoppers 10 and 11 are formed by partially projecting the outer wall of the tank, but of course, another member may be attached to the tank body 1 by spot welding or the like to form the projection. . Further, if a protrusion having a height lower than that of the stoppers 10 and 11 is separately provided in the vicinity of the rotation range of the stoppers 10 and 11, the handle 6 can be more stabilized when the tank is transported.

Reference numeral 12 is an oil meter, which is a transparent plate made of resin or glass attached to the side surface of the tank body 1 through a packing (not shown) and an oil meter metal fitting 13 so as not to overflow the fuel oil during refueling. Therefore, the user can visually check the amount of oil in the tank body 1. Reference numeral 14 denotes a burner which is provided in the petroleum burning device 2 and which receives the fuel oil supplied from the oil pan 3 and burns.

Next, the operation of supplying fuel oil to the tank body 1 will be described. First, the lid 5 is removed from the oil filling port 4, fuel is supplied from the oil filling port 4, the lid 5 is screwed, and then the handle 6
If the handle 6 is lifted, the handle 6 rotates until it hits the upper stopper 10 and then stops, so that the tank body 1 can be lifted. If you carry it to an oil burning appliance and lift the bottom of the tank body 1 with the other hand while holding the handle 6 with one hand, the tank body 1 can rotate around the fulcrum 7 and be smoothly inverted. It may be set in the oil pan 3 of.

Further, in order to take out the emptied tank main body 1 from the oil receiving tray 3 and change it from the inverted state to the upright state, the above procedure may be performed. With this configuration, the tank can be smoothly rotated from the upright position to the inverted position or from the inverted position to the upright position while holding the handle 6 with one hand at the time of refueling, so that even a woman or an elderly person can refuel without difficulty. Therefore, even if the hand becomes dirty with fuel, there is no danger of the hand slipping and dropping the tank, and it is possible to provide a safe and easy-to-use cartridge refueling tank. Further, since the handle 6 and the mounting member 8 do not project extremely from the side surface of the tank body 1, there is no possibility that the tank or the tank is caught when the tank is inserted into or withdrawn from the oil burning instrument 2, and the instrument or the tank is damaged. Further, although the screw-type lid 5 is used in this embodiment, the same effect can be obtained by using the fitting-type lid 5.

[0013]
