Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cartridge-type refueling tank used for oil-burning equipment such as an oil fan heater and containing petroleum fuel such as kerosene therein.
[0002]
[Prior art]
Conventionally, in general, this type of cartridge type refueling tank is provided with a screw portion in a refueling port cylinder at the bottom of the tank body, and a refueling port cap provided with an opening / closing valve device is screwed to the refueling port cylinder to form a refueling port cap. Is removably attached to the fuel filler tube, so that when fueling, there is a disadvantage that petroleum fuel attached to the fuel filler cap arrives at the hand and gets dirty.
[0003]
In order to solve the above-mentioned drawbacks of the cartridge type refueling tank, for example, as disclosed in Japanese Patent Publication No. 6-56259, it is necessary to cover the refueling port cap with a cap opening / closing device and to perform the mounting and dismounting operation of the refueling port cap. In this way, a hand is prevented from being stained with petroleum fuel at the time of refueling. For example, as disclosed in Japanese Utility Model Unexamined Publication No. 60-81455, a flange portion is provided at the end of a screw portion of a fuel filler cap. It is known that one operation handle is rotatably provided on a flange portion so that hands are not stained with petroleum fuel during refueling.
[0004]
However, in the device disclosed in Japanese Patent Publication No. 6-56259, the cap opening / closing device is separated from the fuel tank when the normal fuel tank is used or when the season is off when the fuel tank is used for an oil fan heater or the like. There is a concern that the operation handle may be lost due to being placed in a position where it is placed, and the operation handle disclosed in Japanese Utility Model Laid-Open Publication No. 60-81455 has only one operation handle. It is easy to swing and unstable, and when the tip handle of the operation handle does not protrude sideways from the tank body when falling, sufficient distance between the filler cap and the tip handle of the operation handle is secured. When the operation handle is grasped, there is a concern that the hand may come into contact with the filler cap when the operation handle is grasped, thereby damaging the hand or soiling the hand with petroleum fuel.
[0005]
Also, in the conventional type, since the filler cap and the filler cylinder are screw-connected, it is necessary to rotate the filler cap at least once when attaching or removing the filler cap. This cannot be done quickly, especially when the filler cap is provided with one operation handle.When the filler cap is rotated more than once, it is necessary to change the operation handle many times. However, the operation handle must be supported by another hand so as not to fall down to the flange portion side, so that simple operation with one hand cannot be performed.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described circumstances, and has a sufficient length of a distance between a fuel filler cap and a distal end grip portion of an operation handle in a limited space that does not protrude sideways from a tank body. It is another object of the present invention to eliminate the instability of the operation handle at the time of attaching / detaching the filler cap, and to enable quick attachment / detachment of the filler cap by simple operation.
