Hold it in cap 2. By operating the fuel pump 12 in this state, kerosene is sucked out from the kerosene tank (not shown) through the pipe 13 as shown by the broken line arrow A in FIG. The cartridge tank 1 is then replenished, and the air in the tank 1 is discharged into four parts through the opening 3 of the base 2 and the gas vent hole 15 of the holder 9, as shown by the dashed line arrow. Problems to be Solved by the Invention (For example, Japanese Utility Model Application Publication No. 62-70238) However, in the above configuration, the kerosene flow path (broken arrow) and the air flow path (--dotted chain arrow) in the cap 2 are The structure is such that the liquid kerosene and the gaseous air collide with each other, and as a result, it may not be possible to refuel quickly into the cartridge tank 1, or if you try to refuel quickly, there may still be a small amount left in the tank 1. Even when there is no kerosene in it, the kerosene discharged from the notch 14 of the discharge pipe 8 hits the inside of the mouthpiece 2, and the force of the collision causes kerosene to blow out along with air through the opening 3 and gas vent hole 15. As a result, the area around the cartridge tank and hands got dirty.

の外に放出される。According to the structure described in the following, the present invention first attaches and connects the adapter to the cap of the second liquid storage container during liquid transportation, and the valve body of the cap is pushed open by the tip of the discharge pipe of the adapter, At this time, the discharge port opened in the discharge pipe is located below the lower end of the mouthpiece. Next, by operating the pump unit in this state, the liquid is transferred from the first liquid storage container to the second liquid storage container by the pump unit. At this time, the liquid passes through the discharge pipe of the adapter and is discharged from the discharge port to the second liquid storage container, and at the same time, the air in the second liquid storage container flows through the opening of the mouthpiece and the discharge pipe. The liquid is discharged to the outside of the second liquid storage container from the gap between the liquid and the flow section.
さて、空気放出に関しては口金の開口部径を一定として

び液体の流通をスムーズに行うことができる。Now, regarding air discharge, if the outer diameter of the entire discharge pipe is made smaller while keeping the opening diameter of the mouthpiece constant, air resistance will be less and machining will be easier, but at the same time the inner diameter will also be smaller, and the flow path resistance on the liquid side will be large. Become. Therefore, the flow rate decreases. By making the outer diameter of only the discharge pipe and the flow section facing the opening of the cap smaller than the others, the air passage area can be increased and the air and liquid can circulate smoothly.

を汚さずに給油が可能になる。During refueling, as described above, the discharge port opened in the discharge pipe is located below the lower end of the mouthpiece, so even if the force of the liquid to be discharged is strong, the liquid will not collide with the inner wall of the mouthpiece. without flowing into the second liquid storage container. Therefore, the liquid does not collide with the inner wall of the cap and blow out air and liquid together from the opening of the cap due to the force as in the conventional case, and the liquid can be smoothly transported to the second liquid storage container. In other words, the flow path resistance due to residual air is small, and refueling can be performed quickly and in a short time.Moreover, the liquid does not leak outside from the vicinity of the joint between the adapter and the mouthpiece, making it possible to refuel without getting your hands dirty.

The opening 29 is sealed and closed when the adapter 20 is not connected to the base 23. That is, the compression spring 41 is a biasing means that always biases the valve body 43 in a direction toward closing. Further, a valve body case 44 which is caulked and fixed to the inside of the cap 23 and to the outside of the valve body 43 guides the valve body 43. The side surface of the valve body case 44 has a large open window 45 formed therein. The opening range of the opening window 45 is such that when the actuator 20 is coupled to the base 23, the opening range extends from at least the tip end 31 of the discharge pipe to a position above the discharge port 38.

く手を汚さずに給油ができる。The lower the resistance during air discharge, the greater the amount of liquid flowing from the discharge port 38. Furthermore, since the discharge port 38 opened in the discharge pipe 30 is located at a position lower than the lower end 25 of the mouthpiece 23, the liquid to be discharged (even if the force is strong, the liquid collides with the wall of the mouthpiece 23). Therefore, as in the conventional case, the liquid hits the inner wall of the cap 2 and the force causes the opening 3 of the cap 2 to flow into the second liquid storage container 22. This has the effect of preventing the liquid from boiling over into the tank J and allowing the liquid to be smoothly transferred to the second liquid storage container 22.In other words, the liquid and air collide violently within the nozzle 23 during refueling. Since they do not fit together, there is little flow resistance due to residual air, allowing quick and short refueling, and there is no leakage of liquid to the outside from the area where the Akubuta 20 and mouthpiece 23 are connected, allowing refueling without getting your hands dirty. .
