Abstract

(57) [Summary] [Purpose] By making a case housing a mobile phone emit light in the dark, it is possible to easily confirm the existence of the place where the mobile phone is placed. [Structure] The case body is made of a foamed resin sheet in which a light-emitting body is dispersed in part or all. A transparent protective sheet is provided on the resin sheet so as to cover the surface.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a radio telephone and various portable devices, particularly to a mobile phone case which is used for storing and carrying a mobile phone, and whose case body emits light even in the dark so that its presence can be visually confirmed. It is.

[0002]

[Prior art]

 A mobile phone case is used to store and protect a mobile phone in a safe place such as a pocket, bag, handbag, etc. That is being done. Conventionally, as such a mobile phone case, those described in Japanese Utility Model Publication No. 7-29849, Japanese Utility Model No. 3016201, and Japanese Utility Model Publication No. 3016202 are known.

[0003]

[Problems to be solved by the invention]

 By the way, mobile phones have been increasingly miniaturized with the rapid progress of performance in recent years, and with this, storage cases of small shapes corresponding to the device main body have been developed one after another, but if the size becomes smaller, When mobile phones are closed or misplaced due to diversification of places, misplaced or misplaced places can cause unexpected situations, especially at night or in the dark, in emergencies.

The present invention has been made in view of the above-mentioned problems of the conventional technology, and an object of the present invention is to make the case body emit light in the dark so that it can be used at night or in the dark. To enable instant confirmation of the presence of a mobile phone even when the power is turned off, and to provide a highly practical mobile phone case with a simple configuration and low cost. It is.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the mobile phone case according to the present invention comprises a case body 10 having a front panel 1, a rear panel 2, and left and right side panels 3.4. Alternatively, the entirety is constituted by the independent foamed resin sheet 11 in which a granular light emitting body is dispersed.

Further, it is desirable to provide a transparent synthetic resin protective sheet 12 on the independent foamed resin sheet 11 in which the particulate luminous body is dispersed so as to cover a part or the entire surface of the sheet.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the case body 10 includes a front plate 1, a rear plate 2, and left and right side plates 3.4, on which a bottom plate 5 and an opening / closing cover 6 are provided. ing. A window 7 is provided on the front plate 1, and a transparent plate 8 such as vinyl is attached to the window 7 by bonding, peripheral welding or sewing.

Such a case body 10 is formed of a closed-cell resin sheet 11 in which a granular light-emitting body 9 is dispersed except for a transparent plate 8 of a window portion 7. The independent foamed resin sheet 11 has a thickness of about 0.5 mm. In order to prevent the surface from being contaminated by a thin plate having a thickness of about 5 to 4.0 millimeters, a transparent synthetic resin protective sheet 12 is integrally or separately provided so as to cover the surface.

The independent foamed resin sheet 11 is made of a material such as atsutsu vinyl (EVA) and dispersed with a luminous body 9 such as phosphorus, sulfide or aluminate, particularly preferably strontium aluminate. It is formed by foaming 2 to 15 times, particularly preferably 6 times, and can be obtained by slicing it into a sheet. The thus obtained independent foamed resin sheet 11 contains the luminous body 9 on the entire surface and in all the layers, and 50% or more of the normal volume is a void portion. Efficiently absorbs and accumulates light, and emits light in the dark. The emission color is light green in the case of strontium aluminate.

[0011]

[Action]

 When the case body 10 housing the mobile phone is left in the dark, the portion excluding the window or the whole emits light with a sheet in which the luminous body is dispersed, so that the location of the luminous body can be easily confirmed.

In the daytime or under an electric lamp, light is efficiently stored, and light is emitted in a place where luminance is lower than that of a sheet in which a light-emitting body is dispersed, so that light can be repeatedly used. The independent foamed resin sheet 11 in which the granular luminous body is dispersed is completely protected from external impact and friction because the surface is covered with a transparent synthetic resin protective sheet 12, and is luminous because it is transparent. Also, it does not prevent the phosphorescent performance. Further, the independent foamed resin sheet 11 can be colored to a desired color by using a transparent colored synthetic resin sheet.

[0013]

[Effect of the invention]

 In the present invention, as described above, a part or the whole of the case body 10 is constituted by the independent foamed resin sheet 11 in which the particulate luminous body is dispersed, so that the case body itself emits light in the dark. Yes, it can be easily searched for even at night or in the dark, and in the daytime or under an electric light, the luminous action progresses naturally and the luminescent action can be maintained for a long time, so that it can be used semipermanently. In addition, the mobile phone case can be provided at low cost and high practicality without being hindered by the light emitting function and the light storing function because it is externally protected and transparent because it is covered with the protective sheet.
