It is characterized in that at least one or more decorative portions 10 having a shape that hardly reflects and deteriorates by reflecting light are provided at an arbitrary portion of the surface sheet 5 made of synthetic leather material or artificial leather material. Further, the decoration part 10 includes a reflection figure part 12 that reflects light and a crimping figure part 16 that overlaps with a figure formed by the reflection figure part to form one decoration figure. Further, the reflective figure portion 12 is formed by applying a retroreflective color paint to the top sheet 5 by screen printing. Furthermore, the press-fitting graphic part 16 overlaps the graphic formed by the reflective graphic part 12 to form a three-dimensional figure by heat-pressing the shape to be a single figure on the topsheet 5 with a press. It is formed. Moreover, the reflective figure part 12 apply | coated to the said surface sheet | seat base 5 is formed according to the convex shape or concave-shaped part formed in three dimensions by the press-fitting figure part 16, It is characterized by the above-mentioned. Furthermore, the decoration unit 10 is characterized by comprising various emblems, floral patterns, animal patterns, geometric patterns or cartoon / anime character figures that call attention of school children.

Therefore, the decorative portion 10 is three-dimensionally formed on the surfaces of the large side gusset portions 4 and the cover plate 7 constituting the main storage chamber 3 of the school bag body 2, thereby arousing schoolchildren's interest in the school bag 1. Can increase purchasing motivation. Moreover, since the decoration part 10 is formed by heat-pressing the top sheet 5, there is no fear of deterioration due to secular change even if it is used for a long period of time, and schoolchildren can use it for a long time with attachment. In addition, the decorative portion 10 provided on the surfaces of the large gusset portions 4 and the cover plate 7 on both sides is formed by using a reflective material, so that the decorative portion 10 can be used as a bicycle or automobile light when going to school early in the winter.

The school bag 1 includes a school bag body 2 made of artificial leather, synthetic leather, or the like, and a lid plate 7 that covers the school bag body and a back belt 8 that carries the school bag on the back.

The school bag main body 2 includes a main storage room 3 for storing large items such as textbooks and notebooks, a sub-storage room 6 for storing various teaching materials such as calculation tools, and money and important things such as school expenses and teaching materials. It is constituted by a front pocket (not shown) formed so that it can be opened and closed by attaching a zipper to the opening to be accommodated.

The surface sheet fabric 5 of the school bag body 2 is a known artificial leather obtained by coating a polyurethane resin material on the surface of a lightweight, non-woven fabric having strength and flexibility. For example, a product name “manufactured and sold by Kuraray Co., Ltd.” It is desirable to use “Clarino” (registered trademark), a product name “Cordle” (registered trademark) manufactured and sold by Teijin Cordley Co., Ltd. or a product name “Amaretta” (registered trademark) manufactured and sold by Kuraray Co., Ltd.

The decoration part 10 provided on the surface of the large gusset part 4 constituting the school bag 1 and the surface of the cover plate 7, as shown in FIG. 1, arouses the interest of school children who use the school bag, and promotes the purchase desire of the school bag. Shapes that can be used, such as various emblems, floral patterns, animal patterns, geometric patterns, or cartoon / anime character figures, are formed according to the color of the school bag.

As shown in FIG. 2, the decorative portion 10 has a reflection graphic portion 12 formed of a reflective material that reflects all or part of its shape to light, and is superimposed with the reflection graphic portion to form a single pattern. It is formed in combination with the crimping graphic part 16. As the reflective material used for the reflective figure portion 2, a known reflective material is used, and for example, a fluorescent paint, a luminous paint, a retroreflective paint, or the like is used.

However, the fluorescent paint is inconspicuous due to its low reflection efficiency when illuminated at night. The luminous paint is preferably a retroreflective paint because the reflection efficiency gradually decreases due to aging and cannot be used for a long time. In this retroreflective coating material, as shown in FIG. 7, a reflective material 23 is located on the back side of a minute glass bead 21 contained in the coating material, and incident light is specularly reflected by the refraction of the bead and the reflective material. As a result, the light is reflected in the incident direction, so that the reflection efficiency is good and the light can be viewed from a distance.

As shown in FIG. 7, the retroreflective coating has a particle size of 80 to 110 μm and a refractive index of 1 to 9 in a solvent 20 made of, for example, a known synthetic resin emulsion or synthetic resin hot melt adhesive. Two or three glass beads 21, a reflector 23 made of mica having a particle size of 15 to 25 μm, and an arbitrary pigment are formed by stirring together. A pigment or dye is used as the colorant mixed in the solvent 20, and by mixing this colorant, any color retroreflected light having a chromatic color can be obtained by attaching the colorant to the mirror surface of the reflective material.

As shown in FIG. 4, the reflective graphic portion 12 is applied to the top sheet 5 by applying a part or all of the design by a known printing method such as screen printing, gravure printing or coating printing. Application by silk screen printing is preferred from the viewpoint of labor and workability of printing. After apply | coating the reflective figure part 12 to the surface sheet | seat base 5, it adhere | attaches by heat-drying or natural-drying the reflective figure part 12. FIG.

The crimping graphic part 16 is formed by combining the pattern of the reflective graphic part 12 and forming a single pattern on top of the reflective graphic part 12 so that the surface sheet base 5 is heat-pressed to form an uneven pattern. Form three-dimensionally. The thermocompression processing is performed by known high-frequency dielectric heating processing, preferably high-frequency welder processing. Therefore, the decorative portion 10 having a concavo-convex pattern formed by heating and press-bonding the surface of the topsheet 5 with a press machine is deteriorated even when the school bag 1 is used for a long period of time. The current situation can be maintained without doing so.

As shown in FIG. 5, the reflective graphic portion 12 applied to the topsheet base 5 bulges to the surface side of the topsheet base 5 by matching with the convex portion of the concavo-convex pattern formed by the crimped figure portion 16. You can show it in a state. Furthermore, as shown in FIG. 6, the concave shape portion of the crimping graphic portion 16 and the reflective graphic portion 12 can be formed to coincide with each other, and the reflective graphic portion 12 having a different color in both the concave and convex patterns or the arbitrary concave and convex portions. A pattern rich in variations can be formed.

The figure of the decoration part 10 formed on the surface of the surface sheet fabric 5 is consumed by forming various emblems, floral patterns, animal patterns, geometric patterns or cartoon / anime character figures that attract the attention of school children. Demand can be aroused.

The overlapping of the figures constituting the decorative portion 10 can be formed without shifting the design by overlapping the plates with the same reference point (not shown) with the same technique as the printing. Furthermore, since the reflective graphic portion 12 is applied by silk screen printing, and can be multicolored according to the application depending on the type or shape of the school bag, it can be formed in a wide variety of shapes.

The reflective figure part 12 constituting the decoration part 10 is a reflective figure by the light of the car or the streetlight even in the winter school when it becomes dim due to the use of a retroreflective coating that reflects the light of the car or the streetlight. Since the part 12 can reflect efficiently and can recognize the schoolchild who is walking quickly, it can prevent a traffic accident beforehand and can go to school safely.

Hereinafter, the operation of the embodiment of the present invention will be described. A decorative portion 10 having an arbitrary shape is provided on each of the large side gussets 4 of the main storage chamber 3 constituting the school bag 1 and the top sheet material 5 constituting the cover plate 7. As a result, schoolchildren's interest in the school bag can be aroused and the willingness to purchase the school bag 1 can be increased.

The decorative portion 10 is formed by applying a reflective graphic portion 12 made of a retroreflective coating to an arbitrary portion of the surface sheet 5 by silk screen printing, and then heating the upper surface of the antireflective graphic portion by a known high-frequency dielectric heating process. The reflective figure part 12 can be integrally formed in a three-dimensional manner by matching the convex part of the concavo-convex pattern or the concave part, or any part of the concavo-convex pattern by pressure bonding.

Since the decorative part 10 forms the graphic of the reflective graphic part 12 and the press-fitted graphic part 16 as different plates, there is a possibility that the pattern of the pressure-fitted graphic part 16 superimposed on the reflective graphic part 12 may be shifted. Therefore, by providing a reference point (not shown) provided on the decorative portion 10 and aligning the reference point, the reflective figure portion 12 applied to the topsheet 5 is formed into a three-dimensional shape bulging to the surface side. You can show it up. Furthermore, the recessed part formed by the press-fitting figure part 16 and the reflective figure part 12 can also be made to correspond.

Therefore, since the decoration part 10 can be expressed three-dimensionally, the force of the graphic of the decoration part 10 is increased, and the schoolchild's interest in the school bag is attracted, and the purchase intention of the school bag 1 can be promoted.

The decoration part 10 provided on the large gusset part 4 or the cover plate 7 of the school bag 1 reflects the light of the car or the streetlight in the winter when dusk is early by using the retroreflective paint for the reflective figure part 12. Since schoolchildren who are leaving school can be recognized from a distance, traffic accidents when leaving school can be prevented.

The decorative portion 10 can be diversified by expanding the variations of the decorative portion 10 by forming various patterns on the surface sheet 5, for example, a character such as a cartoon or anime character, a plant or a flower, In addition, school children can show interest in the school bag and can increase their willingness to purchase.
