Abstract

(57) [Abstract] [Problem] A synthetic resin collar that can be detachably attached to the inside of a collar of school clothes can be kept clean, and an odor and darkening can be prevented to keep it clean and beautiful white. Providing an antibacterial color that can be used as a color. SOLUTION: Antibacterial parts 4 and 6 containing an antibacterial agent are formed on at least a surface of a collar 1 made of a synthetic resin for a collar of a school uniform. The antibacterial parts 4 and 6 may constitute the whole of the collar 1, or may be formed only on the surface of the main body 5 made of ordinary synthetic resin. As the antibacterial agent, a silver-based inorganic antibacterial agent is particularly preferable.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a collar that can be attached to a stuffed collar of school uniform.

[0002]

[Prior art]

 Conventionally, synthetic resin collars have been molded from polyethylene or polypropylene, but there are problems such as the generation of offensive odors and darkening with long-term use. In particular, there is a problem that young people who wear school uniforms often sweat and tend to become unsanitary. Furthermore, the school uniform itself may be washed, but even then, the collar is removed, so it is easy to forget to say that the collar is kept clean.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention aims to provide an antibacterial color that can keep the color clean, prevent bad odor and darkening, and can be used as a clean and beautiful white color forever.

[0004]

[Means for Solving the Problems]

 The first invention of the present application is a collar 1 made of synthetic resin, which is detachably attached to the inside of the stuffed collar 3 of the school uniform 1, in which at least the antibacterial portions 4 and 6 containing the antibacterial agent are provided on the surface. The above problem is solved by providing an antibacterial collar characterized by being formed.

A second invention of the present application is, in the collar 1 according to the above-mentioned first invention, that the whole is composed of an antibacterial part 4, and the antibacterial part 4 is made of a synthetic resin containing a silver-based inorganic antibacterial agent. We provide products characterized by being remolded.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a collar according to an embodiment of the present invention, (A) is a plan view of the collar, and (B) is a central longitudinal sectional view of the collar according to the first embodiment. (C) is a central longitudinal cross-sectional view of the collar according to the second embodiment. FIG. 2 is a front view showing a usage state of the same color.

The collar 1 is detachably attached to the inside of the stuffed collar 3 of the school uniform 2, and is formed of a flat plate made of synthetic resin in the shape of a horizontally long trapezoid that is substantially the same as the shape of the stuffed collar 3. . A plurality (five in the figure) of locking holes 11 are formed near the lower end of the collar 1, and the locking holes 11 are engaged with locking protrusions 31 provided on the inner side of the collar 3. As a result, it is detachably attached to the inside of the closed collar 3.

The collar 1 according to the first embodiment is wholly made of a synthetic resin mixed with an antibacterial agent, and as shown in FIG. Make up. Although various antibacterial agents can be used, a silver-based inorganic antibacterial agent (silver-substituted inorganic ion exchanger) is suitable. Although the type of synthetic resin is arbitrary, polyethylene, polypropylene, or other synthetic resin used for conventional collars may be used.

The collar 1 according to the second embodiment includes a main body 5 made of a normal synthetic resin, and an antibacterial section 6 formed on the surface of the main body 5. The antibacterial part 6 is formed by forming a coating layer containing an antibacterial agent on the surface of the main body 5. As this coating layer, a resin component for forming a coating film containing an antibacterial agent may be used.

The present invention can be carried out in any of the first and second embodiments described above, but the first embodiment is advantageous in that the antibacterial part is not likely to be peeled off and can withstand long-term use. Is. The amount of the antibacterial agent blended is arbitrary, but in the case of the silver-based inorganic antibacterial agent, 0.01% by weight or more of the total antibacterial parts 4 and 6 is suitable. If it is less than 0.01, the antibacterial performance will be insufficient. Further, the upper limit of the blending amount is such that the resin does not extremely deteriorate, and it may be appropriately changed depending on the relationship with the synthetic resin or the resin component for forming the coating film. A sufficient antibacterial effect is exhibited at about 0.5 to 3% by weight.

[0011]

【Example】

 Next, an example based on the first embodiment of the present invention will be shown. As an example, 1.0% by weight of a silver-based inorganic antibacterial agent (trade name "NOVALON" manufactured by Toagosei Co., Ltd.) was kneaded into 99.0% by weight of polyethylene, and the whole was injection-molded. A color 1 which was designated as the antibacterial part 4 was prepared.

As a comparative example, a color containing no antibacterial agent was prepared by injection molding of 100% by weight of polyethylene.

The results of testing the antibacterial properties of these examples and comparative examples are shown in Table 1. The test method was as follows: Example and Comparative Example were cut into a 5 cm × 5 cm plate, and the bacterial solution After inoculating 2 ml and storing at 35 ° C., the surviving bacteria were washed out, and the viable cell count was measured by the pour plate culture method and converted into the viable cell count per plate (25 cm ² ).

[0014]

[Table 1]

As shown in Table 1, it was confirmed that the examples exhibited a remarkable antibacterial effect as compared with the comparative examples, and the malodor and darkening of the color caused by fungi and mold were prevented. It is possible. Further, in this example, the above-mentioned silver-based inorganic antibacterial agent is used, and the silver ion is strongly bound to the inorganic ion exchanger, so that the antibacterial effect is maintained for a long time without volatilization or elution. In addition, no skin irritation was observed in the primary skin irritation test of rabbits, so it is safe and there is no risk of environmental pollution. It has also been confirmed that it has excellent chemical resistance, washing resistance, and weather resistance, and that there is extremely little discoloration under sunlight.

[0016]

[Effect of the invention]

 As described above, the invention of the present application can provide an antibacterial color that can keep the color clean, prevent odor and darkening, and can be used as a clean and beautiful white color forever. Furthermore, in the second invention of the present application, there is an advantage that the antibacterial part is not peeled off and can be used for a long time, and the silver-based inorganic antibacterial agent in which silver ions are strongly bound to the inorganic ion exchanger is used. As a result, it is possible to provide an ideal color that has no volatilization or elution, its effect lasts for a long time, is safe, has no risk of environmental pollution, and has excellent chemical resistance, washing resistance, and weather resistance. It came out.
