[Industrial applications]

 This device is designed to fill a gas container with a predetermined concentration of an inspection gas into a gas container provided with a void-shaped blowing tube made of a thermoplastic resin that is gas-impermeable and flexible, and then connects the gas container to the gas container. When the gas alarm is inspected, the tip of the blowing capillary is melt-sealed, and the tip of the blowing capillary is cut and inserted or contacted with the inspection port of the gas alarm to be inspected, and the filling part is pressed with a finger. By injecting the inspection gas into the inspected gas alarm device, it is possible to accurately inspect whether or not the gas detection function of the inspected gas alarm device is correct.

[Prior art]

 A conventional container for enclosing and storing this type of inspection gas is disclosed in Japanese Utility Model Publication No. 50-42793. As shown in FIG. 6, the container 14 has a small-diameter opening 12 and can be sealed. A gas generator for inspection in which a gel-like solid solvent 15 containing an organic solvent with high volatility is stored in a flexible container 11 equipped with a The gas in the flexible container 11 is pressed out, compressed and deformed to be blown out from the small-diameter opening 12 and brought into contact with the gas detection device to be inspected. " It can be recognized that a mode is disclosed in which a gel-like solid solvent 15 containing an organic solvent having a high property is stored, and the lid 14 is opened each time it is used. (The number of each component is different from that of the original publication.)

Therefore, in the container 11 that encloses and stores this type of inspection gas, when a gas detection device such as a gas alarm is newly installed or regularly inspected, a predetermined detection is normally performed. In order to inspect whether or not to operate, the purpose is to make it possible to blow out the inspection gas in a desired direction easily and easily at any time. Then, in order to perform the above-mentioned inspection, conventionally, a container 11 provided with a lid 14 which can be sealed as described above is generated from a solid solvent 15 which is gelled by adding a surfactant to a highly volatile organic solvent. It was using gas. As another method, the gas emitted from a commercial cigarette lighter was not ignited and was sprayed near the inspection port of the gas alarm for inspection.

On the other hand, the gas detection device is, for example, a natural gas, LP gas, or coal gas (manufacturing gas) for a gas leak alarm device, and a ventilation notification alarm for notifying that the indoor air is polluted for ventilation. For applications, carbon monoxide gas, etc. is being developed for each application so that it can operate properly when a gas leaks, depending on the type of gas. In recent years, improvements have been made to prevent malfunctions due to interfering gases unrelated to gas leaks such as alcohol.Furthermore, in addition to simply detecting fuel gas leaks, incomplete combustion of gas appliances A combined gas alarm system has been developed that can detect gas at the same time with a single gas leak alarm.

[Problems to be solved by the device]

 In other words, in order to check the gas alarms according to their respective uses in this way, it is necessary to use different types of inspection gas according to their purpose. Required to be placed. In this way, gas detectors are becoming more sophisticated and multifunctional, and there is a pressing need to deal with inspection gases that inspect gas detectors.

As described above, among the conventionally used inspection gases, the main component of the gas emitted from the cigarette lighter is isobutane, so it is suitable for the inspection of LP gas alarm devices. There are drawbacks that are not necessarily suitable for inspection of alarms for natural gas and manufactured gas. Further, since the gas generated from the gelled solid solvent is usually ethyl alcohol, there is also a disadvantage that it is not useful for a gas alarm device provided with measures against malfunction due to alcohol or the like.

In particular, all of the conventional inspection gas generators shown in FIG. 6 have a storage container for the inspection gas and a screwing lid 14, so that a volatile solvent is screwed into the storage container. There was a problem that it leaked from the part 13 and could not be used at the time of use. Further, in the container 11 for enclosing and storing such a test gas, since the test gas blowing port 12 is the opening 12 formed in the flat surface portion, the inside of the test gas alarm device or the like is It was difficult to determine whether the inspection gas was effectively contacting the gas sensor of, and there was a fundamental problem that only uncertain inspection results could be obtained in the end.

Furthermore, in a container that stores and stores this kind of inspection gas, the inspection gas is not enclosed, but the raw material that generates the inspection gas is dissolved in a volatile solvent and stored. Therefore, it is not a method applicable to all gas species. In addition, the concentration of the test gas changes due to environmental changes such as temperature and weather, and the gas concentration also changes depending on conditions such as the number of ejections and the ejection interval. It was an undeniable drawback to exist.

Therefore, the present invention provides various advanced and multifunctional gas detection devices in order to solve the problem that the conventional container for enclosing and storing the inspection gas has. On the other hand, by directly enclosing the various inspection gases that correspond to each other precisely in a container made of a flexible synthetic resin that is a stable material for the gas, it is always stored at a constant quality and concentration for a long period of time. In addition, it is possible to provide a test gas filled container capable of achieving stable supply of test gas, which can blow out a fixed amount of spraying at a proper concentration and timely by a simple operation during use. It is what
