However, under the present circumstances in which hologram products are often used when only a hologram is attached to the surface, it is becoming difficult to think that the hologram product is interesting enough. It was

In particular, since the hologram image is a stereoscopic image as it is, it is more realistic than an image having a normal plane expression, but it is only a still image, The sense of reality was very inferior to that of.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and its object is to:
It is not a single image but an interesting image,
The image is to provide a realistic glass.

[0007]

Further, the method for producing a transparent liquid container is characterized in that a hologram is formed on the side surface by rotating while rotating in contact with a heated cylindrical stamper in synchronization.

[0014]

Since the transparent liquid container such as glass has a cylindrical shape and the multiplex hologram can be used as it is, the transparent liquid container such as glass with hologram as described above can be used. Further, since it is a transparent liquid container such as a glass and a cup, the contents thereof are filled with various liquids having different refractive indexes such as water, water mix, juice, beer and tea.

Due to this difference in refractive index, each optical path becomes a different optical path, and even when the same light source is used, it is possible to change the hue of the hologram image, the image itself, and the like.

[0016]

The embodiments of the transparent liquid container with hologram according to the present invention will be described below in more detail with reference to the drawings.

Example 1 First, as shown in FIG. 1, a glass having a transparent and cylindrical glass side surface 1 and a transparent glass bottom surface at the lower end of the glass side surface 1 is used. Of course, the entire side surface of the glass need not be transparent, and the upper and lower ends and the like may not be transparent. In this case, on the contrary, the visibility may be improved by this configuration.

Also, as for the bottom surface, only the peripheral portion which does not disturb the illumination may be transparent and the other portions may be opaque. In this case, it may be possible to prevent the illumination from being directly viewed without passing through the hologram, and in this case, the visibility may be improved by this configuration.

In the present embodiment, a hologram having minute irregularities corresponding to the hologram image 2 is provided on the outside of the side surface 1 of the glass. This hologram may be provided on the inner side or may be provided on both sides to form a combined image.

The hologram provided is a transparent hologram. Therefore, it may be completely transparent, but may be transparently colored such as red, blue and yellow. Further, the glass needs to be transparent, but at least one of the side surface and the bottom surface may be colored.

Although this glass is made of glass, it may be made of various plastics or may be made of a composite material having a plastic layer provided on the surface of the glass.

At this time, the hologram image is provided on the glass body, but a hologram film provided on a film of plastic or the like may be wrapped around the side surface. As the plastic, various resins that are transparent, colored, transparent, or translucent can be used, but a resin having excellent adhesiveness, adhesiveness, or shrinkability is preferable so that the image does not float, but an adhesive, etc. It may be fixed with. Further, it is preferable that the tableware has weather resistance and strength.

Reference light is required to display this hologram image, but in this example, a separate coaster is used. This coaster is provided with a light bulb 5 inside, and generates a reference light.

As the manufacturing method, a photocuring resin having a hydrofluoric acid resistance (for example, negative photoresist O
The resist 6 made of MR-85 (manufactured by Tokyo Ohka Kogyo Co., Ltd.) is almost uniformly applied not only by a coating method such as roll coating but also by various film forming methods. (See Fig. 2)

Next, a photomask 7 on which a hologram pattern 8 which is an interference fringe of a multiplex hologram is recorded is covered and exposed.

The photomask has a cylindrical shape with a diameter slightly larger than that of glass, and has a multiplex hologram image recorded on its inner surface.

In this exposure process, the glass 11 is used as shown in FIG.
After aligning the photomask 7 with the photomask 7 and fixing the position, a cylindrical black sheet as a blocking material was attached to the inner surface of the glass, and exposure light was applied from all directions. This exposure light is light having a wavelength at which the photo-curable resin is cured, and specifically, ultraviolet light is used. At this time, if it is not possible to perform the batch exposure from all directions due to equipment, the partial exposure may be performed little by little, or the exposure may be performed while rotating.

Next, the resist is developed by NMR-W (manufactured by Tokyo Ohka Co., Ltd .: trade name). Of course, various resists other than this can be used.

Further, the glass was buffered with hydrofluoric acid (50%).
It was immersed in HF: 40% NH ₄ F = 1: 15) and pulled up for a suitable time (depending on the image, about 1 to several minutes for a general image) when the hologram image was formed by etching. Next, it was immersed in acetone to dissolve and remove the photocurable resin and washed with water to obtain a glass with hologram.

When this hologram-equipped glass was placed on a coaster with a light bulb as shown in FIG. 6, a beautiful hologram image similar to a rainbow hologram, in which various colors were seen by changing the viewing angle, emerged.

When the glass was filled with water, a holographic image having a different color from the above image emerged. Furthermore, when water was added to the whiskey, the whole image turned amber and a high-quality hologram image emerged.

In the case of the present invention, since it is necessary to apply the reference light from the inner surface of the glass, a reference light generating device such as a light bulb is required for the coaster, desk, etc., but the reference light generating device is incorporated in the bottom surface of the glass. If so, you don't need any other equipment.

Further, the multiplex hologram of the present invention is a cylindrical holographic stereogram, and obtains a stereoscopic image of a subject in a horizontal direction of 360 °.

Although the above resist has been described as a case of a photo-curing resin, a photo-melting resin may be used when exposing with a negative pattern.

Example 2 The only difference is that the structure is almost the same as in Example 1 or the material is a thermoplastic resin (styrene resin) suitable for food containers. In this case,
Other resins may be used.

In this manufacturing method, as shown in FIG. 5, the stamper 9 is wound around a glass-shaped heater 10 which is fitted to the side surface of the glass. Then, as shown in FIG. 6, the thermoplastic resin is stamped at an appropriate temperature to obtain plasticity, and the glass 11
By rotating for one round while contacting with, a multiplex hologram similar to the stamper 9 was obtained. In addition,
A method in which the stamper remains flat and a hologram image is formed on the stamper while the glass is rolled thereon may be used.

<Example 3> A lenticular glass was obtained by rolling a lenticular sheet of the same material as in Example 2 into a cylindrical shape and providing the bottom surface. On the other hand, a hologram was attached after accurately aligning with the lenticular in the same manner as in Example 2.

As a result, as shown in FIG. 7, the glass side surface 1 and the glass bottom surface 3 are formed.
The lenticular 15 is formed on the glass 3, and the hologram is formed on the glass outer side 14, and the hologram image 2 can be recognized from the viewpoint 12.

At this time, the hologram comprises a hologram 19 when the content is empty and a hologram 20 when the content is liquid. When the content is empty, it is empty as shown in FIG. By the optical path of the reference light 17 of the above, it hits the hologram 19 in the sky and becomes the hologram image 2.

Further, when the content is a liquid, as shown in FIG. 9, the hologram 20 when the liquid enters is hit by the optical path of the reference light 18 when the liquid enters and another hologram image 2 is formed. Become.

To achieve this, as shown in FIG.
The lenticular is designed such that the longitudinal direction of the lens is the circumferential direction of the glass. As a result, as shown in FIG.
Different types of images coexist depending on the optical path.

[0042]

According to the present invention, hologram images other than the reflection hologram can be used in a transparent liquid container such as glass.

Further, since the liquid container can be made transparent, the hologram image can be recognized while confirming the contents, so that the image can be enjoyed at ease.

Further, since the color tone of the image and the image pattern itself change at the time when the contents are poured, it is possible to give a sense of consciousness and give interest to a person other than the viewer. Also, in terms of reality, since the method of the multiplex hologram is used, it looks as if an image really exists inside the liquid container. Especially when using a lenticular,
Since the image itself changes, the unexpectedness is fully exerted.
Furthermore, an easy manufacturing method thereof can be provided.
