An oxygen mask with an oxygen cylinder has been generally used as a respiratory protection device to be used when there is a risk of harming the human body, but recently, due to the fact that it is heavy and inconvenient to carry, the Oxygen-generating respirators using oxygen-generating agents such as potassium superoxide (KO 2 ) and sodium peroxide (Na 2 O 2 ) that react with carbon dioxide and water to generate oxygen have been developed. ing. These are generally composed of a face piece, a breathing bag, an oxygen generating can and the like, and a representative one thereof is that shown in JP-A-58-127664.

を経て酸素富化ガスとして再び人体に吸入される。In the former case, a breathing bag is connected to the half-face mask, and an oxygen generating can is provided inside the breathing bag by exposing only the lid part to the outside of the bag, and the inlet of the oxygen generating can is connected to the half-face mask via the exhalation valve. The outlet is opened in the breathing bag, and the inhalation valve is interposed between the breathing bag and the half-face mask.
Exhaled air discharged from the human body enters the oxygen generating can from the half-face mask through the exhalation valve, and the oxygen generated by the reaction of carbon dioxide gas and water in the exhaled gas with the oxygen generating agent is added to the exhaled breath inside the breathing bag. After being discharged to the human body, it is again inhaled by the human body as an oxygen-enriched gas through an intake valve and a half-face mask.

間形とされたものである。In the latter, a face mask such as a full face mask, a half face mask, or a mouthpiece, a breathing bag, and an oxygen generating can are sequentially connected from top to bottom, and an expiratory valve and an inhalation valve are connected to the face member, and the expiratory valve and oxygen are connected. A generating can is one connected by an exhalation passage tube. Exhaled air discharged from the human body descends from the half-face mask through the exhalation valve and the exhalation passage tube and enters the oxygen generating can,
The gas to which oxygen is added is discharged into the breathing bag, rises while being cooled in the breathing bag, and is again inhaled into the human body through the inhalation valve and the half-face mask. Both are basically closed-circulation oxygen-generating respirators of the same principle, but generally the former is a short-time type in which a relatively small oxygen-generating can is installed near the half-face mask. The latter is a long-time type in which a relatively large capacity oxygen generating can is provided under the breathing bag.

It is necessary to store the oxygen generator in a state where it is shielded from the outside air. For this reason, a method of sealing the half-face mask that communicates with the outside air, a full-face mask, a face piece part such as a mouthpiece to prevent invasion of outside air, sealing the entrance and exit of the oxygen generation can, and destroying this seal in preparation for use A method for providing a mechanism for removing (Japanese Utility Model Publication No. 50-50299) and an oxygen generating agent are filled in a cartridge so that this cartridge can be inserted into an oxygen generating can. Normally, this cartridge is airtight so that carbon dioxide gas and moisture are not permeated. Sealed in an inert gas atmosphere and stored in a bag of a different sex, then take this out of the bag when using and store it in an oxygen generation can (Shokai Sho 60-99).

用的でないなどそれぞれ問題点があった。However, the sealing of the face piece from the outside cannot be completed completely because the shape of this part is complicated, and since it has elasticity such as rubber, it may peel off during storage. Further, sealing the inlet / outlet of the oxygen generating can and providing a destruction mechanism or the like with this makes the structure extremely complicated, and the processing is troublesome. Furthermore, if the cartridge is filled with an oxygen generating agent and stored in a bag, it must be taken out and stored again in an oxygen generating can when it is used, which is complicated in operation and practical in an emergency. There were problems such as not.

Easily retrieved. At this time, since there is a flange-shaped convex portion 15 ′ close to the opening, the lid is
There is no risk of injury by touching the cut edge of the opening after removal of 15 or damage by touching the respiratory protection. At the same time as being taken out, the breathing bag 3 is instantly inflated by the action of the spring 12 so that it can immediately breathe and is attached to the human body. The exhaled breath exhaled from the human body into the half-face mask enters the oxygen generating can 7 through the exhalation valve 8. When the exhaled air passes through the oxygen generating can 7, the moisture and carbon dioxide in the exhaled gas react exothermically with each other to generate an excessive amount of oxygen. The high-temperature oxygen-enriched gas in which the oxygen concentration is enriched and the carbon dioxide gas is reduced in concentration is discharged from the outlet 5 of the oxygen generating can 7 into the breathing bag 3 and inside the breathing bag 3 outside the intake cylinder 11. While being cooled down, it is cooled and reaches the lower end of the intake cylinder 11. Here, the oxygen-enriched gas is reversed, sucked up in the intake cylinder 11 and rises, reaches the half-face mask 2 via the intake hole 6 and the intake valve 9 and is inhaled by the human body. Circulation breathing is performed in a form that is repeatedly cut off from the outside air.

At this time, it is preferable to provide a convex portion that bulges like a collar inside the container close to the opening in order to prevent the hand or respiratory protective equipment from touching the cut remaining in the opening. . The position where the automatic depressurizing valve is provided is the bottom surface, the upper surface, and the side surface of the container, but the flat surface of the container is preferable because of the ease of mounting, and in particular, the automatic depressurizing valve as shown in FIG. 2 and FIG. Is preferably set on a cover or the like, and attached according to the positions of the flow holes provided in the container.

樹脂などのオイルやグリースを薄く塗布してもよい。As an automatic depressurization valve, it is possible to appropriately discharge excess gas that gradually accumulates in the container to prevent pressure rise in the container and prevent outside air from entering the container. While keeping below 0.3Kg / cm 2 G
Even if an external pressure of about 0.05 Kg / cm 2 G is applied, it is possible to prevent outside air from entering the container. The type is not particularly limited as long as it is an automatic pressure relief valve that can satisfy such conditions, but the one illustrated in FIGS. 3A and 3B is convenient because it can be made relatively small. Among them, the one using a rubber tube as shown in FIG. 3 (a) has a simple structure and is practical with few troubles. In the automatic pressure relief valve of FIG. 3A, for example, the cylindrical body 23 has an outer diameter of 1.5 to 3.0 mm and a length of 8.
0 to 20 mm, inner diameter 1.0 to 2.0 mm, depth 4.0 to 1.0 mm, discharge hole 22
Can be relatively small with a diameter of about 0.8-1.5 mm. The rubber tube 24 is made of synthetic rubber such as natural rubber or chloroprene, so-called insect rubber is used, and its length preferably covers the entire tubular body 23, and its inner diameter cannot be unconditionally specified due to the elasticity of the rubber or the like. Is usually 50 to 99%, preferably 90 to 98%, and has a thickness of 0.3 to the outer diameter of the tubular body 23.
It is selected in the range of ~ 2.0 mm. In addition, in order to completely prevent the outside air from entering the container even when the internal pressure of the container becomes equal to or slightly lower than the external atmospheric pressure due to the temperature change during storage, etc., a non-volatile material is formed on the outer peripheral surface of the cylindrical body 23. A liquid, for example, oil or grease such as silicon or fluorine resin may be thinly applied.
