Description

Bracelet and sticker for easily checking fever with the naked eye {BRACELET AND STICKER FOR FEVER CHECKING}

The present invention relates to a bracelet and a sticker that can easily detect fever with the naked eye.

The present invention relates to a bracelet and a sticker that can easily check a user's heat with the naked eye. Infectious diseases such as COVID-19 are highly contagious and can be transmitted through even brief contact. Therefore, the confirmed person or those who have come in contact with the confirmed person are isolated separately to prevent further transmission. However, the higher the contagiousness, the more difficult it is to know where the person was infected. Therefore, in multi-use facilities used by many people, fever is checked upon entry and those with a fever are not allowed to enter to prevent possible infection. In the event of a confirmed person, the store is forced to suspend operation, but if a vaccine is not developed, an infected person can come out at any time from a place where the route of infection cannot be identified, and the number of infected persons may increase rapidly, especially in multi-person facilities.

However, it is impossible to live without economic and social activities for a long period of time until the COVID-19 vaccine is vaccinated nationwide and collective immunity is developed in the state where the vaccine for COVID-19 has not been performed. In order for this to happen, people need to gather at least little by little. Currently, we are meeting or gathering while wearing a mask, but there are people who do not take it seriously even if they have fever symptoms. Sometimes it doesn't work right.

In addition, even if a fever check is performed, if you take an antipyretic agent, fever may occur only when the effect of the antipyretic agent is low, and fever symptoms may appear late.

In this regard, the Korean Utility Model Application No. 20-2009-0011711 'Fever Sensing Wristband' provides a wristband that allows you to easily detect body temperature anytime, anywhere in daily life regardless of time and place. The temperature change part is small when worn on the wrist, and the part that checks the temperature is often excited, so it has the disadvantage of not being able to check the body temperature change properly.

In addition, conventionally, the silk screen printing method was used when printing using Zion pigment for products that check changes in body temperature using Zion pigment. The above utility model also uses the silk screen printing method to configure the part to check the temperature. Since the silk screen printing method has a certain thickness on the printed surface, it is easy to detect the change in temperature when it comes into contact with the skin, but a roller is used. Since it is difficult to print the rotary printing method with the thickness produced by the silk screen printing method, silk screen printing method has been usually used when Zion pigment is used. However, the silk screen printing method has the disadvantage that it is not suitable for mass printing due to the slow printing speed, and the silk screen printing has the disadvantage that the quality of the print is deteriorated because the general 4th printing cannot be applied.

An object of the present invention is to provide a bracelet that is attached to the wrist in order to solve the above-described problems, but can be easily confirmed that the color changes according to body temperature.

In addition, it is possible to bring about the same color change as silk screen printing while performing rotary printing rather than silk screen printing, and the purpose is to make a smooth print by enabling 4 or 5 degree printing of the rotary method.

In order to achieve the above object, it relates to a bracelet that can easily detect heat with the naked eye, wherein the bracelet is in the form of a paper strip and has an adhesive applied to one end so that it can be attached to the wrist after being wrapped around the wrist (11). ) is formed, and on the outer surface of the bracelet, an advertisement unit 12 on which information and advertisements are printed and a body temperature sensing unit 13 that changes color according to body temperature are formed. It can be printed through.

The ink used for printing the body temperature sensing unit 13 is prepared by mixing 180 to 220 parts by weight of a binder resin with respect to 100 parts by weight of the Zion pigment.

When the body temperature sensing unit 13 requires a background color, it is prepared by further mixing 10 to 20 parts by weight of the background color ink with respect to 100 parts by weight of the Zion pigment.

The sum of the weight of the background color ink and the Zion pigment should be 20 parts by weight or more and 30 parts by weight or less based on 100 parts by weight of the ink mixture.

The diluent may be 27 to 30 parts by weight based on 100 parts by weight of the ink mixture.

The body temperature sensing unit 13 includes a background portion 14 having a contrasting background color so as to easily detect a color change, and a color change unit 15 that actually changes color.

According to the invention as described above, it has the effect of providing a bracelet that can easily confirm that the color changes according to body temperature. In addition, by using rotary printing, it has the effect of making beautiful quality printing.

1 is a view showing an embodiment according to the present invention;

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The present invention provides a bracelet that can be worn directly on the user's wrist and can check the wearer's heat. The bracelet provided in the present invention is made of paper, so it is easy to manufacture, and the user can easily wear it on the wrist. can do. The bracelet shown in FIG. 1 has an elongated band shape, and an advertisement unit 12 and a body temperature sensing unit 13 are formed on the outer surface of the bracelet. The advertisement unit 12 may print an advertisement of a sponsor who helped to produce the bracelet, an advertisement of the side providing the bracelet, or how to use the bracelet.

The body temperature sensing unit 13 includes a color changing unit 15 that changes color according to the body temperature of the wearer. In addition, it may further include a base portion 14 on which the color change does not occur so that it is easier to recognize that the color change occurs.

The base portion 14 and the color change unit 15 maintain the same color before the temperature change occurs, and when they come into contact with the skin, the color of the color change unit 15 changes. Conventionally, there have been some products that change color by body temperature, but since these products do not know what the original color is when the color change occurs, even if the color change occurs, the color change could be passed without recognizing the color change inadvertently. However, in the present invention, After the color change occurs, the base part 14 is placed so that the color change can be recognized immediately, and the color is usually maintained as the base part 14, but the color is changed when it touches the skin. 14) and the color of the color change unit 15 can be easily recognized by the user or people around the user.

When Zion pigment is used, a color change can be easily detected when the base portion 14 is present because a color-changing gradation is shown centering on the area in contact with the skin. The base part 14 is preferably formed to surround the color change part 15, but the base part 14 may be formed only at both ends of the color change part 15 or only at one end so that the color can be contrasted immediately. may be

In the advertisement unit 12, advertisements of the sponsor who provided the cost for manufacturing the bracelet and the method of using the bracelet may be printed. It is difficult and it is difficult to print as many volumes as you want. In the present invention, by using a rotary method using a roller, printing is possible in 4 degrees or 5 degrees, and mass printing, which is difficult with the silk screen method, is possible.

The rotary method is a method to increase the printing speed by printing one cycle every time the roller rotates. may be damaged. However, the silk screen printing method was mainly used because there was a disadvantage that the color change did not occur properly because the minimum concentration required for color change was not reached even if Zion pigment was added to the ink used for the rotary method.

In order to overcome this, in the present invention, the ink composition is configured to enable rotary printing, and the color change can be seen even with rotary printing by repeating printing by passing the roller several times. The ink used in the rotary method should have a viscosity suitable for printing, but if the amount of Zion pigment is insufficient, it is difficult to see the color change depending on the temperature. In the present invention, for this purpose, printing is performed repeatedly several times using ink formulated to have an appropriate viscosity for rotary printing, rather than printing at once. That is, after passing through one roller, the same part is printed several times using ink having the same or similar composition. In general, four-color printing should pass through four rollers, but in the embodiment including the Zion pigment, four additional rollers are passed. Therefore, in order to produce a product according to the present invention while printing in 4 colors, about 8 rollers must be passed, and when the Zion pigment is overprinted 3 to 4 times, the change according to the temperature becomes conspicuous. In addition, since such printing is performed while moving on a conveyor belt, fast printing is possible.

The ink used for this rotary printing method is important in the formulation of the ink. It is made by mixing 90 to 100 parts by weight of a diluent and 180 to 220 parts by weight of a binder resin with respect to 100 parts by weight of the Zion pigment.

In addition, if a background color is required, it is made by further mixing 10 to 20 parts by weight of a background color ink that does not change color. Based on 1000 parts by weight of the ink mixture, the sum of the background ink and the Zion pigment should not exceed 300 parts by weight, and the diluent should be about 90 to 100% of the total of the ink.

Although the background color ink is not necessarily required, it makes it easier to detect a difference from the background part 14 when the background color is white rather than white. In the example, red ink was used as the background color and the Zion pigment was used as the blue Zion ink, the color of which fades near 37 degrees Celsius. Therefore, at a low body temperature, the color is a mixture of blue and red, but at a high body temperature, the blue color disappears and only red remains.

However, when Zion pigment is used, it does not change rapidly when it exceeds the threshold of temperature, but changes little by little to show a gradation. When viewed from the outside, it may look like a kind of decoration or design. you will find out immediately

In another embodiment, Zion pigment was used throughout the band to change to a light pink color at 35.1 to 37.5 degrees Celsius, and to stand out red at 37.5 degrees Celsius or higher.

In addition, a darker color was made to appear below 35 degrees Celsius. In this case, one type of Zion pigment can be used, and Zion pigments that lose color when the temperature exceeds 35 degrees Celsius can be used. For this purpose, more rollers can be used to print. However, even when two or more Zion pigments are used, it is recommended to use the ink formulation in the same ratio as mentioned above for 100 parts by weight of the two Zion pigments. Increase the number of rollers for printing pigments.

In the example below, based on 100 parts by weight of Zion pigment, 100 parts by weight of a diluent and 200 parts by weight of a binder resin were mixed with ink (Example 1)

Ink mixed with 70 parts by weight of diluent and 200 parts by weight of binder resin based on 100 parts by weight of Zion pigment (Comparative Example 1)

Based on 100 parts by weight of Zion pigment, 100 parts by weight of a diluent and 150 parts by weight of a binder resin were prepared and ink (Comparative Example 2) was prepared and printed in a rotary method through rollers, but 4 rollers were used for 4 degree printing. Ink mixed with Zion pigment was used for one or four rollers, and the print quality and color change were evaluated in two aspects. As for the print quality, 20 people evaluated the print quality on a scale of 5 out of 5 by visually comparing the print quality of the 4th-printed part and the color change part, and the average was obtained. As for the degree of color change, the degree of color change was visually checked when a hot object was brought into contact, and 20 people evaluated it on a 5-point scale.

2 rollers

4 rollers

print quality degree of color change Example 1 4.5 4.9 Comparative Example 1 2.9 2.7 Comparative Example 2 2.3 2.4

In the case of two rollers, the printing itself is not performed properly, and in Comparative Examples 1 and 2, it can be confirmed that the printing is not performed properly because the diluent and the binder resin are insufficient, respectively. It can be seen that the color change does not occur properly because the printing is not done properly.

In the case of 4 rollers, it is slightly lower than in the case of 4th printing, but it can be said to be at a similar level, and it can be confirmed that the color change is occurring properly at the desired temperature. However, in the case of Comparative Examples 1 and 2, it can be seen that although there is an improvement even if the number of rollers is increased, the improvement is very insignificant.

According to the present invention, non-face-to-face body temperature measurement is possible in real time, and since it is disposable, it can be worn on the skin with confidence, and there is no problem in supply because it can be produced quickly at low cost.

Although a waiting person is created to measure the body temperature of visiting people every time, according to the present invention, the inspection time is shortened and labor costs are also brought about because it is only necessary to check whether the bracelet is worn.

In addition, the present invention provides a sticker that can be attached to a mask or the like. When the sticker provided in the present invention is attached to a mask, body temperature is transmitted through the mask, so that it is easy to check whether or not there is a fever.
