Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to baby diapers. More specifically, the present invention relates to a baby diaper in which a part of the baby diaper is provided with a thermochromic printed image that indicates changes in the baby's body temperature using colors or pictograms.

BACKGROUND OF THE INVENTION In recent years, disposable disposable diapers have become available in large quantities and have become convenient and convenient, but none are equipped with a display that makes it easy to see changes in a baby's body temperature.

Problems to be Solved by the Present Invention The present invention provides a thermochromic printed image on a baby diaper that is in close contact with the skin so that changes in the baby's body temperature can be visualized through color changes. It is intended to help you understand the health condition of your baby.

Means and actions for solving problems The present invention will be explained with reference to the drawings.

The baby diaper of the present invention has a reversible thermochromic printed image with a color change point in the temperature range of 30 to 40 degrees Celsius that displays changes in the baby's body temperature in color or pictograms on the part of the baby diaper that is in close contact with the skin. It is characterized by having been provided.

The thermochromic printed image 2 in the above is a conventionally known thermochromic ink, that is, a known ink based on a combination of an electron-donating color-forming compound and an electron-accepting color developer, for example, more specifically. Specifically, it is a reversible thermochromic ink containing a homogeneous compatible solution of an electron-donating color-forming compound, an electron-accepting color developer, and a color change temperature control agent, and as a suitable example, it is a reversible thermochromic ink that was previously proposed by the applicant. , Special Publication No. 51-35414, Special Publication No. 51-35414
Thermochromic agents disclosed in Japanese Patent Publication No. 44706, Japanese Patent Publication No. 52-7764, etc. can be used. The above-mentioned material shows a sensitive thermochromic property at various temperatures, and the color can be changed from colored to colored by adding or using common dyes, pigments, etc.

In the present invention, a thermochromic printed image 2 is essential, but a non-chromic printed image 3 using general printing ink may be used as appropriate.
can be attached.

Further, the thermochromic printed image 2 can be arranged by placing images with different color change points, color tones, densities, etc. side by side or by overprinting, or by combining with the non-color changeable image 3 by overprinting or the like.

The printed images 2 and 3 may be printed directly on the surface of diaper fabric (non-woven fabric, woven fabric, paper, etc.), or may be printed on a separate sheet material and attached to the fabric surface. , sewing, button attachment, attachment using magic tape (registered trademark), thermocompression bonding (heat sealing), thermal transfer, etc. are effective.

Furthermore, the color of the material itself can be changed by processing the thermochromic material into the fibers themselves constituting the nonwoven fabric, or by adding them to the binder.

The printed images 2 and 3 are arranged in areas of the diaper that are in close contact with the skin, such as relatively thin areas such as the abdomen and side edges, which have good temperature sensitivity to body temperature and are therefore effective. It is. The color change temperature of the printed image 2 is approximately 30 to 40 depending on the thermal conductivity and temperature sensitivity of the placement position.
It can be appropriately set within the temperature range of °C.

Specific examples of the present invention are described below.

(1) After printing the message "I think you have a fever" (non-color-changing printed image 3) using pale pink general printing ink on the surface of a white to light-colored nonwoven fabric cut to a specified size, it was printed in blue at 36.8℃. 15 parts by weight of a thermochromic pigment that changes color to a more colorless state (consisting of a homogeneous compatible solution of an electron-donating color-forming compound, an electron-accepting color developer, and a color-changing temperature control agent), an acrylic acid ester emulsion (solid content approximately 40 %) by using a thermochromic ink obtained by mixing 100 parts by weight of the thermochromic ink, which is overprinted on the non-chromic printed image 3 to cover the image 3. The message "I hope you are doing well" was written in white).

A baby diaper 1 was constructed by attaching the sheet to the inner abdomen of a disposable baby diaper.

(2) Thermochromic color indicators of green, pale pink, and red, which allow you to see normal, slight, and high fevers as color changes, were printed on a support using ink using thermochromic pigments. In the same manner as described above, the baby diaper 1 was constructed by adhering it to the inner surface of the diaper.

Effects of the invention Since the baby diaper 1 of the invention is configured as described above, changes in the baby's body temperature can be easily visualized by color or pictograms when changing the diaper, etc. It is possible to know the health condition of the baby, and the practicality and marketability of the disposable baby diaper can be improved.
