できるようになつている。Conventional structure and its problems In general, a cartridge tank for an kerosene heater is made by seaming the peripheral edges of a tank blank plate 1 and a tank blank plate 2 to integrate them, and also attaching a handle fitting 3, as shown in Fig. 1. It is connected to the tank blank 1 by welding or the like, and can be lowered by hand via a handle 4 pivoted to a handle fitting 3. Further, an oil gauge 5 is attached to the tank blank plate 1, which informs when the kerosene stove is running out when it is in use, and indicates when it is filled with kerosene when refueling.
Furthermore, an oil filler port 6 is attached to the tank blank plate 1,
In addition to serving as a lid, it is also possible to supply kerosene into the kerosene stove using a pin inside the kerosene stove.

The seaming portion with the sealing agent 8 has a sealing agent 8 inside, and is designed to be sealed with this sealing agent 8. This sealant 8 is applied in advance to either the tank blank plate 1 or the tank blank plate 2, and after temporarily drying, the tank blank plates 1 and 2 are assembled, and after the seaming process, the area around the seaming part 7 is re-applied.

み出てくるという問題があつた。 FIG. 3 shows a cross section of a steel plate constituting the tank blank plates 1 and 2. The tank blank plates 1 and 2 are coated with a metal coating 10 on a steel plate 9 that is easily pressure-formed to protect the steel plate 9 from corrosion. It is constructed by covering.
However, the tank blank plate 1 pressure-formed into a predetermined shape
At the corner portions 11, 11', 11'', 11, it is discovered that there are several layers of cracks 12 in the metal coating 10 as shown in FIG. 4. FIG. It is a diagram of a micrograph, showing crack 1.
It can be seen that 2 occurs in many layers. This crack 12 also occurs in this seamed portion during the seaming process. This crack 12 cannot be filled even if the sealant 8 is reheated and melted, and as a result, the seamed portion may not be completely sealed. In other words, as shown in Fig. 2, the sealant 8 is filled inside the seamed part, so if the high temperature (150 to 250°C) is maintained for a long time (more than 3 minutes) during reheating, the air inside will evaporate. The sealant 8 expands and seals the seaming part 7.
It goes outside and spoils the appearance. Therefore, heating is performed for a short time using a method such as high-frequency heating, but even if the sealant 8 becomes low in viscosity, it does not penetrate into the cracks 12 shown in FIGS. 4 and 5 for a short time. Therefore, when kerosene was poured into the tank, there was a problem that the kerosene would seep out.

500000が好ましい。DESCRIPTION OF EMBODIMENTS One embodiment will be described below with reference to FIGS. 6 and 7. FIG. 6 shows a completed tank after the cartridge tank has been seamed, and an organic coating 14 is applied around the seamed portions centering on the corner portions 11. The organic coating 14 is made of, for example, an acrylic resin having an average molecular weight of 20,000 dissolved in a solvent such as toluene or isopropyl alcohol, and is spray applied. At this time, it penetrates into the inside of minute cracks in the seamed part, seals the cracks, and destroys the coated organic film by drying at room temperature to avoid applying large stress to the formation of the organic film. Prevent deterioration. FIG. 7 shows a cross section of this corner portion 11. An organic coating 14 is applied over the cracks that have occurred in the metal coating 10, and the cracks are covered with the organic coating 1.
It shows the state filled with 4. Therefore, the defect rate due to kerosene seepage due to cracks is drastically reduced. By the way, as a result of an experiment on the failure rate (%) of kerosene seepage when acrylic resin was used for the organic coating 14, as shown in the histogram shown in Figure 8, no kerosene leakage occurred except in areas with low and high average molecular weights. I stopped doing it. The reason is not certain, but it seems to be as follows. In other words, it seems that if the average molecular weight of the organic coating material is large, it cannot penetrate into minute cracks, and if the average molecular weight of the organic coating material is small,
This is thought to be because although the cracks are filled, the organic coating agent itself is in a state where it is easily dissolved in the kerosene, so after a while the amount of organic coating agent dissolved in the kerosene increases and eventually cracks appear. According to experimental results, the average molecular weight of organic coating materials is 1000~
500000 is preferred.
ここで従来から市販のものにおいては、処理鋼

れないものである。 Conventionally, there are treated steel sheets on the market with an organic coating on them, but these have organic coatings with an average molecular weight of 1,000,000 or more, and are not subject to severe processing or the above-mentioned pressure. Cracks also occur when the coated metal cracks during forming and seaming. In other words, conventional organic coatings are hard and have a high average molecular weight in order to prevent them from being scratched during the normal distribution process, so they cannot achieve the effects of the present invention. .

ク完成後に本格的な塗装をする必要がない。 In the above embodiment, the treated steel sheet serving as the tank blank was a steel plate with a metal coating, but the metal coating 10 was made of zinc, an alloy of zinc and aluminum, lead, an alloy of lead and tin, aluminum, zinc and nickel, etc. Those containing at least one or more of them as main components are effective. Furthermore, the treated steel sheet is coated with acrylic resin,
Vinyl chloride resin, epoxy resin, melamine resin,
It may be made of polyester resin or the like and has at least one organic coating, and such a material may corrode from human fingerprint marks on the surface of the cartridge tank or be exposed to high temperature and humid conditions. This has the effect of preventing corrosion of the coated metal 10. Moreover, this treated steel sheet is also effective for metal coating 10 which has been subjected to phosphate treatment, chromate treatment, water glass treatment, colloidal silica treatment, alumina sol treatment, and the above-mentioned organic coating treatment. By applying this treatment, the strength against rubbing when loading and unloading the cartridge tank is increased, and by combining such treatments, corrosion resistance and
Abrasion resistance and adhesion of organic coatings can be increased.
By doing this, there is no need for full-scale painting after the cartridge tank is completed.
