Description

[Detailed Description of the Invention] The present invention relates to a glass ashtray, and particularly to a glass ashtray in which the color of the pattern or scenery visible on the inner bottom changes when a cigarette is placed on it.

In the past, temperature-indicating substances have been used in various fields, such as applying temperature-indicating tape or coating temperature-indicating paint to specific parts of equipment for the purpose of temperature control during processes in chemical factories, but for glass ashtrays... Temperature-indicating paints also had problems such as difficulty in application and peeling, and their application was considered impossible.

The present invention is a glass ashtray with a discoloration part formed on the outer bottom surface by two layers of liquid crystal and ink, which are sequentially applied using a screen printing method.

The ashtray of the present invention is characterized in that it has a discolored area on its outer bottom surface consisting of two layers of liquid crystal and ink. If necessary, an adhesive layer is provided below the liquid crystal layer, or an additional adhesive layer is provided above the ink layer,
Furthermore, it is also possible to provide an adhesive layer under the liquid crystal layer and also to provide an adhesive layer on the ink layer.

The drawing shows an example in which the discolored part is cut out from four layers,
FIG. 1 is a central vertical sectional view thereof, and FIG. 2 is an enlarged view of section A thereof.

In the figure, 1 is an ashtray, and 2 is a discolored portion formed on the outer bottom surface of the ashtray 1.

Each layer of the color change section 2 is formed by a screen printing method.

When using this method, printing machines commonly used for printing on bottles, bottles, etc. can be used as is, and automatic, continuous work, overprinting, etc. are possible, and there are many problems such as no misalignment of printing. In addition to its advantages, this method allowed the formation of extremely thin layers of liquid crystal.

First, an adhesive is applied to the outer bottom glass surface of the ashtray 1 by the method described above to form the adhesive layer 3.

Then, before this dries, liquid crystal is applied by the same method to form the liquid crystal layer 4.

Conventionally, it was thought that it was impossible to apply liquid crystal to form a uniform thin layer, but the present invention uses a screen printing method to form a thin layer on the order of microns.

Then, ink is further applied by the same method and baked with ultraviolet rays to form the ink layer 5.

The color of the ink may be any color such as green, navy blue, or red, but black is best for making the discoloration appear more vivid.

Finally, an adhesive is applied to form an adhesive layer 6.

The adhesive layer 3 firmly adheres and fixes the liquid crystal layer 4 responsible for the color change function to the glass surface to prevent it from peeling off, and the ink layer 5 is located behind the liquid crystal layer 4. As mentioned above, the adhesive layer 5 makes the discoloration of the liquid crystal appear vivid, and the adhesive layer 5 covers the liquid crystal layer 4 and the ink layer 5 to isolate and protect them from the atmosphere, water, and other substances.

The adhesive used in the present invention is not particularly limited, but for example, a two-component epoxy adhesive is used.

The embodiment of the drawings in which the discoloration part has four layers has been described above, but when forming two layers of liquid crystal and ink according to the present invention, apply the liquid crystal and apply the liquid crystal, respectively, according to the explanation of the above embodiment.
Of course, it is sufficient to apply ink and bake.

Regarding the ink and adhesive, one or more layers may be electrostatically coated depending on the convenience of the process.

The ashtray of this invention reacts extremely quickly to temperature changes, unlike conventional thermometer tapes, etc., which have a slow response to temperature changes.Moreover, the temperature change range is wide from room temperature to 60℃, so you can freely adjust the discoloration temperature within this range. can be set.

In the ashtray of the present invention, the configuration of the shape of the discoloration part 2 is arbitrary, so if various scenery or patterns are printed as the discoloration part, it will be easier to place a cigarette on it or touch it with your hand. , the colors of these landscapes visible on the inner bottom surface change, and a different flavor emerges, which is extremely interesting as a hobby.

Furthermore, since the discolored portion also changes color due to other environmental temperatures, it is possible to visually capture these temperature changes, which has high practical value.
