The flame tube rolling prevention device of FIG. 1 has one protrusion 2 on the outer surface of the tubular body 1 and has an opening 4 in the longitudinal direction of the tubular body 1.

幅に依存する。The easiness of fitting of the flaming cylinder rolling preventive tool of the present invention to the flaming cylinder, and the difficulty of pulling out the flaming cylinder rolling prevention device when the flaming cylinder is thrown out during use are determined by the elasticity of the material, the flaming cylinder. It depends on the inner diameter of the tubular body 1 to be fitted to the, the thickness of the tubular body 1, the length of the tubular body 1, and the opening width of the opening 4 of the tubular body 1.

選択される。The inner diameter of the tube body 1 of the flame tube rolling preventive, the thickness of the tube body 1, the length of the tube body 1, and the opening width of the opening portion 4 of the tube body 1, which are fitted into the flame tube 3, are determined by the material. It is appropriately selected depending on the resilience and the force of pressing when mounting the flame tube.

さくなると、嵌合させにくくなり、また発炎筒の外径を
超えて大きい場合には、使用時、発炎筒を投げ出した時
に、発炎筒転がり防止具が抜けやすくなる。The inner diameter of the tubular body 1 is usually 4/5 to 1/1 of the outer diameter of the flaming tube 3. When the outer diameter of the tubular body 1 is smaller than 4/5, it becomes difficult to fit the tubular body 1, and when it is larger than the outer diameter of the flaming barrel, the flaming barrel rolling preventive tool is likely to come off during use when the flaming barrel is thrown out. Become.

り、作業性が低下する。The thickness of the cylindrical body 1 is usually 1 mm to 3 mm. If the thickness of the tubular body 1 is thinner than 1 mm, the force for fitting becomes weak, and it becomes easy to pull it out when the flaming tube is thrown out during use, and if it is thicker than 3 mm, the force for fitting becomes strong. As a result, the time required for mounting becomes long and the workability deteriorates.

通常、発炎筒の外径の１／１０〜１／２である。The opening width of the opening 4 in the lengthwise direction of the cylindrical body 1 is
Usually, it is 1/10 to 1/2 of the outer diameter of the flaming cylinder.

に、開口幅が大きい方が好ましい。In the case of polyethylene, for example, the opening width of the opening 4 is 1/10 to 1/3 of the outer diameter of the flaming cylinder, and in the case of polypropylene which is harder than polyethylene and is hard to bend and has high elasticity. Is 1/6 to 1/2 of the outer diameter of the flaming cylinder. In general, a material having high elasticity has a larger opening width.

て、適当な開口幅を選択する。Generally, if the opening width is large, it can be mounted with a small pressing force, but it becomes easy to come out of the flaming cylinder during use.
Also, if the opening width is small, it cannot be installed unless the applied pressure is increased, but it is difficult for the flaming cylinder rolling preventive tool to come off from the flaming cylinder during use.Therefore, select an appropriate opening width considering the type of material, workability, etc. To do.
【００３２】筒体１の開口部４の端面の角部は、面取り

にスムースに嵌合させることができ、より容易に装着す
ることができる。The corners of the end surface of the opening 4 of the cylindrical body 1 are chamfered to form curved surfaces. In this case, the cylinder 1 is replaced by the flaming cylinder
It can be fitted smoothly to and can be mounted more easily.
【００３３】筒体１の外側面に設ける、発炎筒転がり防
止用の突起２の数は、少なくとも１個である。突起２の
数が３個を超えても、転がり防止効果はあまり変らない
ので、３個までで十分である。The number of projections 2 provided on the outer surface of the cylindrical body 1 for preventing the flaming cylinder rolling is at least one. Even if the number of the protrusions 2 exceeds three, the rolling prevention effect does not change so much, and thus the number of protrusions up to three is sufficient.

の場合、突起２の長さを全て同じとする必要はない。The length of the projection 2 can be appropriately selected in consideration of the intended rolling prevention effect, but is usually 1/3 to 1/1 of the outer diameter of the flaming cylinder. For example, the outer diameter is 3 cm
In the case of a φ flame tube, the length of the protrusion 2 is 1 cm to 3 cm. The longer the protrusion 2 is, the more the rolling prevention effect can be improved. Further, when the number of the protrusions 2 is plural, it is not necessary that the lengths of the protrusions 2 are all the same.
【００３５】突起２を設ける外側面の位置は、転がり防
