When filling non-charcoal beverages into non-charcoal beverages such as I cans, the pressure inside the can cannot be expected to increase due to carbon dioxide gas in the beverage.
A liquefied inert gas such as α-nitrogen is dripped into the inside of the can after the beverage is filled just before the can is tightened.

There are two types of devices: an intermittent drip type that drips liquefied inert gas, and a continuous flow type that constantly drips liquefied inert gas. The present invention relates to an improvement in an intermittent downward-direction type device that drips pregelatinized inert gas (only when a can to be filled with liquefied inert gas is transported).

することとなる。The intermittent dripping device that drips pregelatinized inert gas (currently known) is a device that was developed to eliminate the loss of liquefied inert gas between can pitches, which is a drawback of the continuous flow type. Inert gas is dripped into each can. Then, in order to discharge a certain amount of α-inert gas for a short period of time, 0.2kg/0.2kg/
It is operated under pressure control by applying a small pressure of cm2, but the pressure fluctuation is large, about 10X, and because of the pressure, the dropping rate of liquefied inert gas increases, and the liquid level of the contents increases. The pregelatinized inert gas rebounds, and as a result, the variation in the internal pressure of the can becomes large. In other words, even if an attempt is made to bring the internal pressure of the can to an appropriate value, the pressure of the can is almost always lower than Ikg/cm''.As a result, more liquefied inert gas than necessary is discharged.

多いという。In order to eliminate the above-mentioned drawbacks, the direction of movement of the liquefied inert gas is made to match the direction in which the can is conveyed, and Iα-formed inert gas is added in a spray form to soften the shock at the liquid surface of the contents. There have been nine days since the start of the test, but even then there are large variations and the amount of liquid and inert gas used is large.

ソープションポンプの役割を果している。The following are the fruits of the present invention! Examples will be described with reference to the accompanying drawings. FIG. 1 shows an embodiment of the present invention. In Figure 1, a droplet 1/control sensor l″r using an optical fiber method measures the liquid level of liquefied inert gas with high precision (±3 m
m) is detected, and the liquefied inert gas is sent out and seeped out using the electromagnetic on-off valve 2 via the controller IO. The liquid level control sensor 1 has almost no loss rate of inert gas and is highly accurate compared to the thermocouple type or float type used in the 101. In other words, the liquid level of liquid nitrogen is L
Light emitted from a light-emitting element such as ED is transmitted through an optical fiber and utilizes reflection and refraction at the liquid surface. 1:1
．． Therefore, heat E] for humans is almost equal to zero. The light emitting element is L
It is not limited to only ED, but may also be a semiconductor laser. The storage tank for the liquid (inert gas) is composed of a vacuum tank 8, which is evacuated once by a valve 11.The vacuum tank 8 is filled with molecular sieves, which are used to store the liquefied inert gas. In other words, the degree of vacuum achieved with a normal rotary pump is about IQ-3 mml13, but if you pull it with a 1-way rotary pump filled with molecular sieve, 10-4 to 1 when storing α-gelatinized inert gas
0-'mm and 11g, so there is no need to use an expensive turbo vacuum pump to create a high vacuum in advance. In other words, the storage tank itself plays the role of a sorption pump.

いう考え方である。This device is basically an intermittent drip type, but in concept it is an intermittent flow type because no pressure is applied to the liquefied inert gas storage tank. In other words, the idea is to cut the loss part of the flow-down method.

５の引上げ時間の短縮をはかった。In the case of the conventional intermittent dripping method, pressure was applied to the reservoir tank in order to maintain followability on high-speed lines (1200epm), but the equipment was inevitably complicated and expensive. . As a result of intensive study by the present inventors on these points, it was found that even an intermittent flow type can sufficiently follow the same. In other words, in order to reduce the weight of the nozzle rod 5 and improve the solenoid 4 through TiX-like control, in other words, to speed up the control i3j of the solenoid, in the case of a solenoid whose appropriate voltage is 12 volts, the nozzle rod 5 is changed by applying a voltage of 24 volts. The aim was to shorten the lifting time.

クで製作テストした。However, we discovered a phenomenon in which, even with intermittent flow, when operating with one nozzle hole per nozzle, the amount of liquefied inert gas increases, and as a result, the contents scatter more on the liquid surface. did. This resulted in large fluctuations in the can internal pressure. Therefore, by increasing the number of nozzle holes to 2 to 4 per nozzle and reducing the size of the droplets, the scattering of liquefied inert gas was almost eliminated, making it possible to produce products without variations in can internal pressure. became. If you increase the number of holes further, it will become 1
In the nozzle, the droplets re-agglomerated into large droplets and had no effect. Furthermore, even if the holes are separated, the surface of the droplet (the surface of the droplet) becomes larger and evaporates more easily.The material of this nozzle is metal, such as carbon steel or stainless steel. Highly sexual 10~
Heat was transferred from the surroundings from 50 kcal/n+-hr·'C), and as a result, bubbling of the liquefied inert gas occurred near the nozzle 11, making it difficult to drip a fixed amount of liquid. Therefore, Tl (0,2~
In other words, a polymer compound (0.3 kcal/m-hr.degree. C.) was selected, and materials with high impact resistance such as glass, carbon, aramid, or plastic reinforced with boron fiber were fabricated and tested.

Has a function. In other words, depending on the nozzle diameter, the opening and closing time of the nozzle rod 5 is 0 to 40 m5ec.
The flow rate per can of liquefied inert gas can be adjusted between 0.17 and 0.341 by simply changing the flow rate, so it has an extremely flexible function. Usually 20G/2 +
