Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a chemiluminescence device which is utilized for signs, fishing tackles, lighting equipment, accessories, and the like. 
     2. Description of the Related Art 
     FIG. 12 illustrates a conventional chemiluminescence device for attractions and accessories. 
     Referring to FIG. 12, reference numeral 51 designates a transparent cylindrical sealed container. A sealed tube 52 made of glass is arranged in the sealed container 51. First liquid A which emits light chemically when it mixes with second liquid B is charged in the sealed container 51 and the second liquid B is contained in the sealed tube 52. When the sealed tube 52 is broken by bending the sealed container 51 and then the first liquid A mixes with the second liquid B, light is emitted from the chemiluminescence device. 
     Incidentally, there is a demand to prolong an emitting period during which the chemiluminescence device emits light and to increase luminous intensity. To prolong the emitting period and to increase the luminous intensity, an amount of either the liquid A or the liquid B must be increased. In the chemiluminescence device shown in FIG. 12, however, when either the diameter or the length of the sealed container 51 is increased to increase the volume thereof, the following problem arises. Namely, a problem arises in that the sealed container 51 cannot be bent when the diameter of the sealed container 51 is increased. Also, when the length of the sealed container 51 is increased, the length of the chemiluminescence device cannot be determined to be a suitable length for use. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a chemiluminescence device capable of prolonging the emitting period, increasing the luminous intensity, and also with solving the above problems. 
     According to the present invention, a chemiluminescence device is provided, comprising: a first sealed container containing first substance therein which emits light chemically when it mixes with a second substance, light being able to pass through the first sealed container; a hollow protrudent portion protruded from the first sealed container, a shape of the hollow protrudent portion being able to be changed by external force; and a second sealed container containing the second substance therein and arranged in the first sealed container, at least a part of the second sealed container being breakable and arranged in the hollow protrudent portion, the part of the second sealed container being able to be broken by changing the shape of the hollow protrudent portion.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIG. 1 illustrates a first embodiment of the present invention. Referring to FIG. 1, reference numeral 2 designates an oval sealed container. The sealed container 2 is transparent and made from polyolefin resin, for example, polyethylene or polypropylene. Note, the sealed container 2 may be semitransparent. A protrudent portion 1 protruded from the sealed container 2 is formed integrally therewith. The protrudent portion 1 is substantially cylindrical and the center line C of the protrudent portion 1 is approximately coincident with the center line C of the sealed container 2. The diameter, the length, the thickness, and material of the protrudent portion 1 are determined so that the shape of the protrudent portion 1 can be changed by hand. In this embodiment, the protrudent portion 1 is made from the same material as the sealed container 2. The maximum diameter D of the sealed container 2 is approximately two times as large as the diameter D of the protrudent portion 1. A sealed tube 3 is arranged in the sealed container 2. The sealed tube 3 is cylindrical and made from glass. The diameter of the sealed tube 3 is slightly smaller than the inner diameter of the protrudent portion 1. One end portion of the sealed tube 3 is arranged in the protrudent portion 1 and the other end portion thereof extends near to the wall of the sealed container 2. The center line C of the sealed tube 3 is substantially coincident with the center line C of the sealed container 2. 
     First liquid A is contained in the sealed container 2 and second liquid B is contained in the sealed tube 3. When the first liquid A mixes with the second liquid B, light is emitted chemically. The first liquid A comprises, for example, oxalic ester, fluorescent substance, and dibutyl phthalate, and the second liquid B comprises, for example, hydrogen peroxide, sodium salicylate, and dimethyl phthalate. In the conventional chemiluminescence device, the volumetric ratio of the first liquid A to the second liquid B is 10:2˜3. In this embodiment, since the volume of the sealed container 2 can be considerably increased, a large amount of the first liquid A can be contained in the sealed container 2. Therefore, the volumetric ratio of the first liquid A to the second liquid B becomes 10˜20:1. Accordingly, in order to emit light efficiently under this volumetric ratio, molar concentration of component in the first liquid A and the second liquid B is adjusted. 
     When the sealed tube 3 is broken by bending the protrudent portion 1 by hand and then the first liquid A mixes with the second liquid B, light is emitted chemically from the chemiluminescence device. 
     In this embodiment, since a large amount of the first liquid A can be contained in the sealed container 2, the emitting period can be prolonged and the luminous intensity can be increased. Also, the protrudent portion 1 can be easily bent and the length of the chemiluminescence device can be shortened. 
     Further, since an area of lighting surface can be increased by increasing the volume of the sealed container 2, light can be found from farther away. 
     Further, since light is emitted approximately equal toward the entire direction, light can be easily found from the entire direction. 
     Furthermore, although carbon dioxide is generated during the chemical reaction by which light is emitted, since the sealed container 2 is oval, it is not easily deformed by gas pressure. 
     Furthermore, the chemiluminescence device can be easily attached to another member by the protrudent portion 1. 
     Note, a hole may be provided at the protrudent portion 1. In this case, by passing a thread through the hole, the chemiluminescence device can be easily worn as an accessory. 
     Further, the first liquid A may be contained in the sealed tube 3 and the second liquid B may be contained in the sealed container 2. 
     Furthermore, organic fluorescent substance may be added to the material which constitutes the sealed container 2 so that wavelength of light emitted by the chemical reaction is lengthened. For example, when 1-chloro-9,10-bis(phenylethynyl)-anthracene is used as the first liquid in the sealed container 2, the wavelength of light is 520 nm. In this case, when organic fluorescent, for example, 1,4dichloro-5,12-bis(phenylethynyl)-naphthacen(DCBPEN) or aryloxy substituted 3,4,9,10-perylene tetracarboxy diimido, is added to the material which constitutes the sealed container 2, the wavelength of light is lengthened to 600-615 nm. Therefore, the color of light emitted by the chemical reaction can be changed easily. 
     The following is an experimental result for comparing the first embodiment of the present invention and the conventional chemiluminescence device (see FIG. 12). The Table 1 shows the relationship between luminous intensity and elapsed time.

     The second embodiment of the present invention is shown in FIG. 2, wherein the sealed container 2 is spherical. Since the length of the protrudent portion 1 is shorter than that in the first embodiment, the protrudent portion 1 in the second embodiment cannot be bent. Accordingly, the sealed tube 3 is broken by adding impulsive force to the protrudent portion 1. 
     In this embodiment, light is emitted more equally toward the entire direction and sealed container 2 is stronger against gas pressure generated therein. 
     The third embodiment of the present invention is shown in FIG. 3, wherein the sealed container 2 is cylindrical.

Note, the tube may be made from material which is dissolved by seawater in order that the signal sinks when certain time elapses.
