Abstract

PROBLEM TO BE SOLVED: To facilitate refilling of pressurized fuel into a pressurized fuel vessel made of metal by mounting an adapter in an upper part of the pressurized fuel vessel made of metal and pressing down a valve stem when a filling cylinder is inserted into an opening at the center thereof from above to form a filling passage. SOLUTION: When pressurized fuel is filled into a pressurized fuel vessel can 2 used for a movable cooking stove on the table, a square projection 4 of a cylindrical part 3 at the center of an adapter 1 is fitted into a lower bottom part of a filling device 11, and a filling cylindrical part 12 is inserted into an opening at the center of the adapter 1 from above to communicate a filling hole 23 of the filling cylindrical part 12 with a longitudinal hole for supplying liquid 21 of a valve stem 7. The valve stem 7 is pressed down by the filling cylindrical part 12 to open a transverse hole 22 of the valve stem 7 which has been closed by a stem rubber 8 and fill pressurized fuel into the pressurized fuel vessel 2 through a pressurized fuel flow-in port 17. After fuel is filled, the filling device 11 is removed, and the valve stem 7 rises by a coil spring 15 to close the transverse hole 22 by the stem rubber 8.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-sized pressurized fuel container with a refillable adapter and an adapter thereof, and more particularly to a small-sized pressurized fuel tank with an adapter which can be refilled many times and used for a small tabletop cooker for one person. It relates to a fuel container and its adapter.

2. Description of the Related Art In a hot pot cooking at a hotel or the like, a solid fuel is generally used. The solid fuel is sold in blocks of a certain size in an amount sufficient to cook the serving material. However, there are various types of cooking ingredients, such as those that are difficult to boil and those that are relatively easy to pass through.How to use such ingredients to provide delicious and attractive dishes, The current situation is that we are making efforts every day. In such a case, when the solid fuel is formed in a certain size, the heating time is constant, so that the material used for the dish is naturally limited. Therefore, it is necessary to select a material by calculating backward from the heating time. Further, since the heating power cannot be adjusted, even if it is desired to extinguish the fire, it cannot be extinguished. Also,
For example, when using a stove using solid fuel outdoors, such as a barbecue, the fire may be extinguished by the wind. In addition, the thermal power is constant and cannot be adjusted. If you have to be careful not to extinguish the fire and not to burn the material, the enjoyment of the place will be halved. Portable pressurized fuel containers are currently used instead of solid fuels, but are not small enough to be used on a stove for one person, and are disposable and uneconomical, thus increasing waste It will also be.

[0003]

SUMMARY OF THE INVENTION Accordingly, it is a first object of the present invention to provide a small pressurized fuel container with a refillable adapter which can be used, for example, for a tabletop stove for cooking pots for one person. And Also, by mounting the adapter on the top of the small pressurized fuel container, for example, when used in a small tabletop stove, enables the ejection of pressurized fuel,
It is a second object of the present invention to provide a small-sized pressurized fuel container adapter which can be filled with pressurized fuel at the time of filling.

[0004]

According to the present invention, there is provided a pressurized fuel container 2 having a pressurized fuel jet valve at an upper portion, and a tip of a valve stem 7 of the pressurized fuel jet valve located in a central opening 3 '. The adapter 1 is placed on the pressurized fuel container 2 in such a manner that the central tubular portion 3 is erected from the central portion of the adapter 1 and penetrates the central tubular portion 3 to vertically extend the central opening 3 ′. The upper portion of the central cylindrical portion 3 is made larger in diameter than the lower portion to constitute a locking portion for a filling device or a stove mounted thereon, and is engaged with the inside of the peripheral hanging portion 1 '. A stop projection 6 is provided so that the stop can be engaged with the upper part of the pressurized fuel container can 2, and the stop projection 6 is interrupted by a plurality of vertical grooves 5 extending upward from the lower edge of the peripheral hanging portion 1 '. The O-ring 9 is formed in a circumferential groove formed on the lower surface of the central cylindrical portion 3 of the adapter 1. To prevent the pressurized fuel from leaking to the outside, and when stationary, the liquid supply passages 21 and 22 are closed with the valve stem 7 located at the central opening 3 ′ being raised by a spring, and at the time of filling, Alternatively, a small-sized pressurized fuel container with a refillable adapter capable of filling or ejecting fuel by opening the liquid supply passage with the valve stem 7 lowered at the time of ejection. The present invention also includes a circular flat plate portion and a peripheral hanging portion 1 'hanging down from the periphery of the circular flat plate portion. The central cylindrical portion 3 is erected from the central portion of the circular flat plate portion and penetrates the central cylindrical portion 3. A central opening 3 ′ in the vertical direction is formed, and the upper part of the central cylindrical part 3 is made larger in diameter than the lower part thereof to form a locking part with a filling device or a stove mounted thereon, A locking projection 6 is provided inside the peripheral hanging portion 1 'so that it can be locked on the upper part of the pressurized fuel container 2, and the locking projection 6 extends upward from a lower edge of the peripheral hanging portion 1'. The O-ring 9 is fitted in a circumferential groove formed on the lower surface of the central cylindrical portion 3 and is locked on the upper part of the pressurized fuel container. This is a small pressurized fuel container adapter to be used.

[0005]

Since the present invention is constructed as described above, the large-diameter rectangular projection 4 of the central cylindrical portion 3 of the adapter 1 is fitted into the lower bottom of the filling device 11 by one-touch at the time of filling the pressurized fuel. 12 is inserted from above into the central opening 3 ′ of the adapter 1, and communicates with the filling hole 23 of the filling cylinder 12 and the liquid supply vertical hole 21 of the valve stem 7. As the filling cylinder pushes down the valve stem 7, as shown in FIG. 1, the side hole 22 of the valve stem 7 which has been closed by the stem rubber 8 is opened and passes through the pressurized fuel flow population 17 of the housing. A filling passage into the pressurized fuel container 2 is formed. Thus, pressurized fuel can be charged. When the filling is completed and the filling device 11 is removed, the valve stem 7 is raised by the coil spring 15, so that the side hole 22 is closed again by the stem rubber 8, and the ejection valve returns to the state of FIG. When this small pressurized fuel container is used, for example, for a small tabletop stove for one person, the fuel flow path is formed in the same manner. The large-diameter rectangular projection 4 of the central cylindrical portion 3 of the adapter 1 is fitted into the lower bottom portion of a small-sized tabletop stove for one-touch operation, and the fuel ejection passage of the tabletop stove communicates with the liquid supply vertical hole 21 of the valve stem 7. By operating the knob of the tabletop stove, the valve stem 7 is pushed down,
As in the case of filling, a lateral hole 22 is opened and communicates with the inside of the pressurized fuel container 2 through the pressurized fuel flow population 17 of the housing,
A fuel ejection passage from the pressurized fuel container 2 to the tabletop stove is secured, and pressurized fuel is ejected. Thus, the user can freely adjust the heating time and the heating power.
