という問題点がある。2. Description of the Prior Art Breathing apparatus for diving are roughly classified into an open type breathing apparatus and a semi-closed type breathing apparatus or a closed type breathing apparatus. The above-mentioned open breathing apparatus uses compressed air as a source of breathing gas and discharges all breathing gas that has been breathed once into the water.When using it for long-term diving, increase the capacity of the cylinder. However, there is a problem that the weight must be increased.

気を外部に排出しないようにしたものである。On the other hand, the semi-closed breathing apparatus is equipped with an air bag, an exhaust valve, a carbon dioxide gas adsorbing device, and a breathing gas cylinder to remove carbon dioxide gas from the breathing air circulating in the breathing circuit and to remove the carbon dioxide gas. In addition, a small amount of breathing gas is introduced into the airbag to discharge excess breathing air.The closed breathing device has the same structure as the semi-closed breathing device, but has an exhaust valve. Without doing so, it is designed so that excess respiratory air is not discharged to the outside.

うに丸めて外筒５内に挿入せしめる。In the present invention, as shown in FIG. 1, heat-welding is performed each time a predetermined amount of carbon dioxide adsorbent is put into a long bag 8 having air permeability by a conventionally known automatic filling means (not shown). Lateral sealing is performed so that the front side and the back side of the bag 8 are fused at this portion, and this operation is repeated thereafter to form, for example, a continuous strip 10 of four capsules 9 separated from each other. The strip 10 is rolled up as shown in FIGS. 2 and 3 and inserted into the outer cylinder 5.
