  However, in the color rendering glass described in Patent Document 1, since the glass bottom is thick, not only is the design easily damaged and the merchantability is lowered, but the glass is heavy and handling is troublesome.

  In view of such problems, an object of the present invention is to provide a color rendering glass in which an excellent color rendering property can be obtained without the glass bottom being thick and heavy.

  The color rendering glass according to the present invention is a color rendering glass that accumulates light so that the entire glass emits light, and the glass body is manufactured in a bottomed cylindrical shape using a transparent or translucent material, and is formed on the bottom surface of the glass body. Is formed with a storage recess, which is filled with liquid silicon and sealed with a lid. The liquid silicon has a phosphorescent pigment having an average particle size in the range of 50 μm to 150 μm with respect to the liquid silicon. When the phosphorescent pigment settles in the liquid silicon, a high-density layer of the phosphorescent pigment is formed in the liquid silicon. On the lower outer surface, a diffused light reflection layer whose surface is repeatedly uneven is formed to cover the lower outer surface, and the outer surface of the diffuse light reflection layer is frosted to transmit light to the outside of the glass body. Is suppressed.

  One of the features of the present invention is that the storage recess on the bottom of the glass is filled with transparent liquid silicon and sealed with a lid. The liquid silicon is mixed with a phosphorescent pigment and settled, and the high density of the phosphorescent pigment in the liquid silicon. The point is that a layer is formed. Thereby, when the high-density layer of the phosphorescent pigment is irradiated with light, for example, light in the ultraviolet region, and the light irradiation is stopped, the phosphorescent pigment emits light.

  The average particle size of the phosphorescent pigment is in the range of 50 μm to 150 μm. If it is less than 50 μm, not only does it take a long time to settle, but a thick layer of phosphorescent pigment with sufficient thickness is formed. On the other hand, if the thickness exceeds 150 μm, the high density layer of the phosphorescent pigment becomes too thick, and it may be difficult to sufficiently reach the light below the high density layer.

  In addition, the amount of the luminous pigment is mixed with the liquid silicon by an amount in the range of 40 wt% to 70 wt%, while the thickness of the high density layer of the luminous pigment cannot be secured at less than 40 wt%, This is because if it exceeds 70% by weight, the high-density layer of the phosphorescent pigment becomes too thick, and light may not reach the lower part of the high-density layer sufficiently.

  By the way, in the case of a transparent or translucent glass, when light is emitted at the bottom of the glass, the light is transmitted outward, and in the case of a transparent glass, an impression is given that almost no light is emitted.

  The second feature of the present invention is that a light irregular reflection layer is formed on the lower outer surface of the glass, and the outer surface of the light irregular reflection layer is frosted. As a result, the light emitted from the bottom of the glass is diffusely reflected by the diffuse reflection layer at the bottom of the glass and returned to the shape of the glass, and there is little light that passes through the glass and leaks outward. it can.

  Moreover, since the liquid silicon is transparent, the light emitted from the phosphorescent pigment is easily transmitted through the glass bottom. In addition, since the bottom of the liquid silicon is sealed with the lid, the light emitted from the phosphorescent pigment is reflected by the lid and travels into the glass, so that the entire glass can emit light even more brightly.

  Here, considering the function of the lid, the surface of the lid is preferably mirror-finished. Also, since the color rendering glass is constantly washed and requires water resistance, the lid is preferably made of stainless steel.

  Further, the light irregular reflection layer only needs to be formed on the lower outer surface so as to have a surface with repeated irregularities. For example, a transparent or semi-transparent member having a plurality of ice particles or a plurality of ice particles continuously formed in a linear shape. The formed mountain-shaped transparent or translucent member can be formed by being fixed so as to cover the lower outer surface of the glass body.

  The light diffuse reflection layer is preferably made of the same material as the glass body, specifically, a glass material. In this case, as the frost processing method, a chemical frost processing method using hydrofluoric acid or hydrofluoric acid can be adopted.

  In addition, after putting transparent or translucent liquid silicon mixed with phosphorescent pigment into the storage recess, and then putting white liquid silicon into the storage recess, a white liquid silicon layer is formed under the high density layer of the phosphorescent pigment. The luminous brightness of the phosphorescent pigment can be further increased.

  Further, the combination of the above-described color rendering glass and a light emitting element that emits light to the color rendering glass is also novel. That is, according to the present invention, it is a color rendering glass device that accumulates light and emits light from the entire glass, and is composed of a color rendering glass and a light emitting element. The color rendering glass is made of a transparent or translucent material. The bottom of the glass body is formed with a storage recess, the storage recess is filled with liquid silicon and sealed with a lid, and the liquid silicon is within a range of 50 μm to 150 μm. The phosphorescent pigment having an average particle size of the size is mixed in an amount within the range of 40 to 70% by weight with respect to the liquid silicon, and the phosphorescent pigment settles in the liquid silicon, so that the liquid silicon contains While a high density layer of phosphorescent pigment is formed, a light irregular reflection layer whose surface is repeatedly uneven is formed on the lower outer surface of the glass body so as to cover the lower outer surface, and the outer surface of the light irregular reflection layer is formed. The surface is frosted to prevent the transmission of light to the outside of the glass body, and the light emitting element emits light in the ultraviolet region from above or obliquely above the high density layer of the phosphorescent pigment of the color rendering glass. Thus, a color rendering glass device can be provided.

  This color rendering glass device is configured by mixing a phosphorescent pigment and an aggregate with non-phthalic acid-based vinyl chloride, silicon resin, and polytetrafluoroethylene resin, and can further include a phosphorescent coaster on which the color rendering glass is placed.

It is a perspective view which shows preferable embodiment of the color rendering glass which concerns on this invention. It is a figure which shows the example of the irregular reflection layer in the said embodiment. It is sectional drawing of the glass main body in the said embodiment. It is a figure which shows the cross-section of the lower part in the said embodiment. It is a perspective view which shows the example of the phosphorescence coaster in the said embodiment.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 4 show a preferred embodiment of a color rendering glass according to the present invention. In the figure, the color rendering glass 10 is formed in a substantially cylindrical shape using a transparent glass material, and the storage recess 11A is formed on the bottom surface of the glass body 10. The storage recess 11A has an arcuate cross section on the top surface. A step portion 11B is formed at the lower edge of the storage recess 11A.

  In this storage recess 11A, a transparent liquid silicon 13 is placed to a thickness of, for example, about 1.5 mm to 3 mm, and a white liquid silicon 16 is placed, for example, about 2 mm below the transparent liquid silicon 13, and a step portion Liquid silicon 13 and 16 are sealed by fitting a lid 14 into 11B, and a stainless steel plate having a mirror-finished surface is used for the lid 14.

  In the transparent liquid silicon 13, a phosphorescent pigment having an average particle diameter in the range of 50 μm to 150 μm, for example, an average particle diameter in the range of 60 μm to 100 μm, is 40 wt% to 70 wt% with respect to the liquid silicon 13. In an amount within the range of, for example, 50% to 60% by weight. The phosphorescent pigment mixed with the liquid silicon 13 settles downward in the liquid silicon 13, and a high-density layer 15 of the phosphorescent pigment having a thickness of about 1 mm is formed at the boundary between the transparent liquid silicon 13 and the white liquid silicon 16. Yes.

  A diffused light reflection layer 12 is formed on the lower outer surface of the glass body 11 so as to cover the lower outer surface. The light irregular reflection layer 12 is formed of a transparent (or translucent) glass member having an ice particle shape as shown in FIG. 2A or a plurality of ice particle shapes as shown in FIG. It is formed by fixing a continuous mountain range-shaped transparent (or translucent) glass member so as to cover the lower outer surface of the glass body 11, and the surface is a surface with repeated irregularities.

  A chemical frost processing method using hydrofluoric acid or hydrofluoric acid is applied to the outer surface of the light irregular reflection layer 12 to form minute irregularities having a size within a range of 600 mesh to 1200 mesh, for example, and the glass body 11 The transmission of light outward is suppressed.

  When the color rendering glass 10 of this example is used, an LED lamp is used immediately before use, and light in the ultraviolet region is applied from above or obliquely above the color rendering glass 10. Then, the light is stored in the high density layer 15 of the phosphorescent pigment of the color rendering glass 10. When a drink is poured into the color rendering glass 10 and then placed in a dim atmosphere, light is generated from the phosphorescent pigment.

  Since the light diffuse reflection layer 12 is formed on the lower outer surface of the color rendering glass 10 and the outer surface of the light diffuse reflection layer 12 is frosted, the light emitted from the bottom of the color rendering glass 10 is below the color rendering glass 10. Light diffusely reflected by the light irregular reflection layer 12 is returned into the shape of the color rendering glass 10, and there is little light that passes through the glass and leaks outward, so that the entire color rendering glass 10 can emit light brightly.

  Since the liquid silicon 13 at the bottom of the color rendering glass 10 is sealed with a lid 14, the liquid silicon 13 does not leak out even if the color rendering glass 10 is washed.

  At this time, when the color rendering glass 10 is placed on the phosphorescent coaster 20 shown in FIG. 5 and illuminated with an LED lamp to accumulate the light, not only the color rendering glass 10 but also the coaster 20 emits light, thereby further enhancing the atmosphere. it can.

  The phosphorescent coaster 20 shown in FIG. 5 is produced by mixing a phosphorescent pigment and an aggregate with non-phthalic acid-based vinyl chloride, silicon resin, and polytetrafluoroethylene resin to produce a coaster 21 and fitting it into the eye plate. Only 21 may be used.

  In the above example, a white liquid silicon layer is formed. However, the white liquid silicon layer is not necessarily provided.
