のである。BACKGROUND ART Generally, the fluorescent tube part of a fluorescent lamp is made of glass, so it is easily damaged in the event of a disaster such as an earthquake or when something hits it, and broken glass tube fragments scatter. That is a concern. In addition, fluorescent lamps are widely used as a light source in various stores and factories, but the ultraviolet rays of fluorescent lamps cause the fading and deterioration of important products, cause eye fatigue and injury, and protect against ultraviolet rays. It is known that insects fly in. Further, it causes various problems such as scattered glass pieces being mixed in the product.

てから熱風で収縮させるものである。In response to the above-mentioned problems, products aiming at preventing glass scattering have been commercialized. For example, a film type that shrinks by heat is a thin tube-shaped PET resin having a wall thickness of about 100 microns, which is covered with a fluorescent lamp and then shrunk by hot air.

ィルムとしている。Further, as shown in FIG. 25, the type in which the fluorescent lamp is inserted into the bag-shaped cover has two films 12,
Both width portions of 13 are integrated by a binding margin 14 formed by adhering or welding, and both ends in the length direction are configured as openings 15. In this case, one film 12 is an aluminum vacuum deposition surface, and the other film 13 is an ultraviolet absorbing film.

であった。The heat-shrink film type described above adheres the film to the fluorescent lamp by heat, so even if it becomes necessary to replace the fluorescent lamp with the film once it is attached, the film cannot be peeled off and reused. is there. Further, since it is a very thin film because it needs to be heat-shrinked, it is expected that fragments of the glass tube will break through the film and be exposed depending on the time of breakage or an external impact. Further, since the glass tube of the fluorescent lamp is in a negative pressure state, the negative pressure acts on the film that is in close contact with the glass tube due to damage or the like, so that the base is pulled into the film, and the subsequent processing becomes troublesome. I also understood that. Further, since it is necessary to request a professional processor for the step of bringing the film into close contact with heat, it cannot be used in a factory, a store, or the like as needed.

ものであった。In addition, since the adhesive-adhesive film type is attached to a fluorescent lamp with an adhesive, the film cannot be peeled off and reused even if it is necessary to replace the fluorescent lamp once it has been adhered. . Moreover, it was found that wrinkles and air bubbles are likely to enter when the film is attached to the fluorescent lamp, and it is difficult to adhere the film neatly. Furthermore, A in FIG.
As shown in the part, there is a slight difference in the outer circumference between the base of the fluorescent lamp and the joint between the glass tube and the glass tube, but since only a flat film is wound along the outer circumference of the glass tube. Since it cannot be covered along the shape of the joint, it is expected that ultraviolet rays may leak from the joint or broken glass may scatter.

等が十分に解消されていないものであった。Further, the bag-shaped cover type can be easily used and can also improve the illuminance, but since the bag-shaped opening 15 is set wide and the binding margin 14 projects in the width direction, There are more protruding parts in the width direction from the pipe,
The appearance was not good. Moreover, the scattering of glass, the leakage of ultraviolet rays, etc. at the time of breakage from the openings 15 at both ends have not been sufficiently eliminated.

は、さらなる工夫が求められるものであった。As described above, in each of the conventional scattering prevention tools for fluorescent lamps, there are still problems with film strength such as a heat-shrinkable film and adhesion at both ends of the fluorescent lamp. It could not be said that the prevention of the dispersion of the above was completely achieved. Particularly, from the viewpoint that maximum preventive measures should be taken within the range that can be done in advance for risks that may occur in the future in the range of predictability, further devising was required. .

いといった問題も有している。In addition, in each of the conventional anti-scattering devices for fluorescent lamps, there is no one that can be easily installed under the condition that the appearance of the fluorescent lamp is not significantly changed, and similarly, once installed, it is necessary to replace the fluorescent lamp with a new one. Even if it occurs, it has a problem that it cannot be reused.
