が今までなかった。(Technical background of the invention and its problems) Metal cases made of aluminum or the like are generally used as containers for liquids such as coffee or juice. This can block light and air from the outside world. This is because it also has the feature of being resistant to impact. However, this metal case has drawbacks such as difficulty in disposing of it after use and the high cost of the metal material, so to prevent liquid from leaking onto paper, plastic, or composites of these materials, the inner surface is laminated with aluminum foil. What has been done is considered. These materials have the advantage that they are inexpensive and can be incinerated compared to metals when they are disposed of after use. When using materials such as paper as containers for liquids, gas barrier properties can be improved at low cost, and outer back lines can be cut by laminating the inner surface of aluminum foil. If left, the quality of the internal liquid will deteriorate, so it is necessary to seal it in an overflow state. However, due to problems with the filling machine or defects in the container, air bubbles may remain in the container after filling, and these must be disposed of as defective products, but there has been no method to detect this transmission until now.

９Ａと空気部分８Ｂの温度差を見ることができる。(Embodiment of the Invention) FIG. 1 shows a paper container to which the present invention can be applied and an embodiment in which heat is applied to the container. Hot air 2 is blown into the paper container 3 filled with liquid through a heater device l. It is placed at the top. This paper container 3 consists of a main body 3A and a lid 3B, and an enlarged sectional view of the upper part of this container 3 is shown in Figure fjS2. Here, air bubbles are contained in the paper container 3, and by tilting the paper container as shown in FIG. Figure 3 shows the temperature distribution of this paper container 3 detected from the side, that is, from the front in Figure 2, using an external line camera (not shown).The CR7 screen 6 shows the temperature distribution of each part. The temperature distribution is shown by the density of the color, and by comparing it with the temperature scale 10, you can judge the temperature of that part. The temperature distribution of each of the paper containers 9 which are tilted and supported by the supporting stand 8 supported on the stand 7 is shown, and the temperature difference between the liquid portion 9A and the air portion 8B can be seen.
このような構成においてこの発明の詳細な説明すると、
温風２により紙容器３全体が熱せられたところで温風を
停止して少し時間をおくと、液体部分４に接している紙
容器３の部分の温度に比し、空気部分５に接している紙
容器３の部分は熱容量の違いから、高い温度を示してい
る。つまり、液体部分４に接している部分はほぼ室温を
維持している液体に熱が吸収されてしまうので、空気部
分５に接している部分よりＦ￥！、（冷えるのである。A detailed explanation of the invention in such a configuration is as follows:
Once the entire paper container 3 is heated by the hot air 2, the hot air is stopped and after a while, the temperature of the portion of the paper container 3 that is in contact with the liquid portion 4 is lower than that of the portion that is in contact with the air portion 5. The portion of the paper container 3 exhibits a high temperature due to the difference in heat capacity. In other words, heat is absorbed by the liquid in the part that is in contact with the liquid part 4, which maintains almost room temperature, so the heat is absorbed by the part that is in contact with the air part 5. (It gets cold.
従って、赤外線カメラによってその温度分布を見ると、
空気部分の温度分布８Ｂは液体部分の温度分布９Ａに比
し色が濃く見えて高温であることがわかる。これが、紙
容器の中に空気がない場合は、一様に液体部分の温度分
布９Ａの色の濃さとなる。つまり、紙容器３の中に空気
部分５があるかどうかは、赤外線カメラによって得られ

合とか、或いはある設定温度以上の部分がある場合に判
断でき、これにより不良品の判別が回部となるのである
。Therefore, when looking at the temperature distribution with an infrared camera,
The temperature distribution 8B of the air portion appears darker than the temperature distribution 9A of the liquid portion, indicating that the temperature is high. If there is no air in the paper container, the color density of the temperature distribution 9A of the liquid portion will be uniform. In other words, whether there is an air portion 5 in the paper container 3 is determined by analyzing the temperature data obtained by an infrared camera, and if there is a partial temperature difference or if there is a portion whose temperature is higher than a certain set temperature. This makes it easy to identify defective products.
実験による一例によれば、紙容器に６０〜＋００°Ｃ程

分が２８℃となり、この温度差はだいたい３０秒程度以
上は生じており、充分その温度差によって又は設定温度
（例えば３２℃程度）超えたことにより不良品排出信号
を示すことは可能であった。According to an example from an experiment, a paper container is heated to a temperature of several tens of degrees by blowing hot air at a temperature of about 60 to +00°C, and a few seconds after the hot air is stopped, the high-temperature air part rises to 35°C and a low-temperature one. The liquid part reaches 28℃, and this temperature difference occurs for approximately 30 seconds or more, and it is possible to indicate a defective product discharge signal due to the sufficient temperature difference or because the set temperature (for example, about 32℃) has been exceeded.

(Not shown) While the paper container 3 filled with liquid is tilted, gently move it in the direction of arrow N! I! Continuously moving. The movement by this Peltocoveyor begins with a process in which the heating unit 11 heats the body with hot air 2, then passes through a process in which the hot air 2 does not hit, and then the infrared camera 13 is heated by the temperature detection unit 12.
The temperature distribution of the paper container 3 is detected, and if it is determined to be a defective product, it is discharged like the paper container 21 in the next process, the defective product discharge section 14.

なるので紙質である必要がある。FIG. 5 is a block diagram showing the steps leading up to the discharge of defective products as described above. Upon receiving a temperature signal from the infrared camera 13, the temperature detection section 12 inputs temperature data TA to the temperature difference judgment section 15. However, if there is a temperature difference of more than a predetermined temperature in each part of the paper container, or if there is a part with a temperature higher than the set value, a defective product signal TB is manually sent to the defective product discharging section 14, and the defective product is ejected. It will be done. The belt conveyor drive synchronization signal 16 is input to the temperature detection section 12 and the defective product discharge section 14, and when a defective product is detected by the temperature detection section 12, the belt conveyor drive synchronization signal 16 is synchronized with the speed at which the belt conveyor moves. The paper containers are discharged in the process of the defective product discharge section 14. Here, the shape and size of the paper container are not particularly limited, but if the outer surface has a metallic luster,
It must be made of paper because it reflects infrared rays from the outside, making temperature measurement impossible.
