Abstract

PURPOSE:To obtain a cigarette displaying an alarm by the color-development of a paint when the cigarette is burnt to a definite length to prevent the over- smoking of tobacco by printing an alarm mark on a cigarette paper with a heat-sensitive paint which is transparent or white at ordinary temperature and develops a color with heat. CONSTITUTION:A cigarette paper 2 for the wrapping of shredded tobacco leaves 1 is printed with a mark 6 or letters to alarm the over-smoking of tobacco with a heat-sensitive paint which is transparent or white at ordinary temperature and develops a color with heat. Shredded tobacco leaves are wrapped with the paper to obtain the objective cigarette. The heat-sensitive paint is e.g. composed of a leuco dye (e.g. Crystal Violet) and a color-developing agent (e.g. benzyl p-hydroxybenzoate).

Description

[Detailed description of the invention]

0001

FIELD OF THE INVENTION This invention relates to cigarettes.

0002

BACKGROUND OF THE INVENTION Cigarettes are a favorite item of choice for many people. Many adults around the world smoke. Cigarettes are popular among many people, but it has been pointed out that smoking too much can be harmful to your health. In order to minimize the amount of harmful components such as tar and nicotine that are inhaled into the body, many cigarettes are equipped with a filter in the mouthpiece. Even with filters in place, smoking too much cigarettes is not good for your health.

0003

[Problem to be Solved by the Invention] Once a person develops the habit of smoking, it is difficult to stop smoking even though it is known that it is harmful to one's health. You should avoid smoking too much as much as possible.

0004

[Means for Solving the Problems] In view of the above circumstances, the present invention provides a cigarette in which chopped tobacco leaves are wrapped in wrapping paper, in order to prevent over-smoking as much as possible. Cigarettes are printed with markings or text that warn against oversmoking using heat-sensitive paint that is transparent or white when exposed to heat.

[0005]

[Effect] When you light a cigarette and smoke it, it gradually shortens, and when the fire approaches the display mark or text printed with heat-sensitive paint, it becomes sensitive to heat and becomes colored, making the warning mark or text visible. , warns you not to inhale too much.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on specific embodiments shown in the accompanying drawings. FIG. 1 shows a cigarette 3 made of chopped tobacco leaves 1 wrapped in wrapping paper 2. Chopped tobacco leaves 1 are wrapped in wrapping paper 2, and glue 4 is applied to the overlapping portions of the wrapping paper 2 to fix them. A filter 5 for preventing harmful components such as tar and nicotine from being inhaled into the body is connected to one end of the cylindrical body thus formed.

[0007] In this cigarette 3, display marks such as the "no smoking mark" 6 that warns against excessive smoking, or characters such as "Be careful not to smoke excessively" are displayed on the filter 5.
At an appropriate position between the vicinity and the center of the wrapping paper 2, that is, at the position indicated by A in FIG. Print with heat-sensitive paint that fully develops color at temperatures between 70°C and 100°C. If the heat-sensitive paint is not designed to develop color at around 70℃, there is a risk that the color will develop at room temperature due to some conditions.
It is necessary to set the temperature so that the color starts to develop around 0°C. There are dye-based and pigment-based heat-sensitive paints.
Thermal paint used for thermal paper for facsimiles and thermal paper for word processors can be used. An example of the composition of heat-sensitive paint is:
Some products are made of a leuco dye and a color developer, and when heat is applied to this, the leuco dye and developer react and develop color. Since a trademark such as "ABC" and a number such as "1234" are printed on the wrapping paper 2, this thermal paint printing may be performed at the same time as this printing.

Dye-based thermal paper uses a colorless dye (leuco dye) and a color developer such as phenol as basic materials, and a binder is used to bind these to the base paper. Also,
Various additives are added at the same time to improve performance such as recording suitability. Typical colorless dyes used in thermal paper include crystal violet lactone and 3-diethylamino 6-methyl 7-anilinofluorane. The former is blue and the latter is black.

[0009] There are many substances that cause a coloring reaction when heated and melted with a colorless dye, but generally, bisphenol A, which has little coloring property, is mainly used in the production of heat-sensitive paints. Among the color developers, benzene P-hydroxybenzoate has extremely high color development sensitivity even when used alone as a color developer compared to the conventionally used bisphenol A, so it is used when particularly high sensitivity is required. .

[0010] Since the sensitivity is insufficient when using a color developer alone, it is used in combination with a wax sensitizer such as fatty acid amide.

[0011] In the above, the tipped cigarette 3 has been described, but the present invention can be similarly applied to the double-cut paper cigarette 13 shown in FIG. FIG. 2 shows a double-cut paper-wrapped cigarette 13 in which chopped tobacco leaves 11 are wrapped with wrapping paper 12. Chopped tobacco leaves 11 are wrapped in wrapping paper 12, and glue 14 is applied to the overlapping portions of the wrapping paper 12 to fix them.

[0012] In this both-kirigami cigarette 13, the wrapping paper 12
A "no-smoking mark" is placed at an appropriate position between the vicinity of the mouthpiece and the center, indicated by B in Figure 2, and is visible from any direction along the circumference to warn against excessive smoking.
Marks such as 16 or words such as ``Be careful not to inhale too much'' are printed on the circumference so that they can be seen from any direction using heat-sensitive paint that is transparent or white at room temperature and fully develops at 70℃ to 100℃. I'll keep it. There are dye-based and pigment-based thermal paints, and thermal paints used for facsimile thermal paper and word processor thermal paper can be used. An example of the composition of a heat-sensitive paint is one consisting of a leuco dye and a color developer, which reacts and develops color when heated. This heat-sensitive paint is printed on the wrapping paper 12 with a trademark such as "XY
Z" and a number such as "6789" are printed, so it is sufficient to do this at the same time as printing.

When one end of the above-mentioned tipped cigarette 3 or double-cut cigarette 13 is lit and smoked, the length gradually becomes shorter.
When a fire approaches a display mark or text printed with heat-sensitive paint, it becomes sensitive to heat and develops color, making the warning mark or text visible and issuing a warning of excessive vaping.

[0014]

Effects of the Invention As described above, the present invention provides a cigarette in which chopped tobacco is wrapped in wrapping paper, and the wrapping paper is provided with a display that warns against oversmoking by using a heat-sensitive paint that is transparent at room temperature or white in color when exposed to heat. These are cigarettes with marks or letters printed on them, and when the cigarette is smoked for a certain length of time, the heat-sensitive paint changes color due to the flame and issues a warning, which helps prevent over-smoking. Furthermore, since the cigarette paper is simply printed with heat-sensitive paint and can be printed simultaneously with other trademarks and numbers, it is possible to prevent over-smoking at an extremely low cost and is extremely economical.
