Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light reflecting tape used for a band widely used in, for example, a shoulder band such as a water bottle, a front band of a dog collar or a school bag, daily necessities, clothes, and industrial products. The present invention relates to an interior strip-shaped base material.

[0002]

2. Description of the Related Art In general, in order to alert a driver of a car or the like when walking at night or the like to prevent a traffic accident, the light of a car such as clothes or bags of a pedestrian should be used. Many of them have attached a light reflecting tape that receives and reflects light. A glass bead type in which a reflective layer such as glass powder and a coating layer made of a synthetic resin or the like are formed in a sheet shape on the reflective surface of the light reflective tape so as to have light reflexivity, or an extremely small size. There is a prism type in which a pyramid-shaped prism is formed in a sheet shape.

By the way, in the case of clothes or portable goods, in particular, bands, the light reflecting tape cut to a predetermined size on a conventionally used leather or synthetic leather is called an adhesive or an adhesive. It was attached by means.

[0004]

However, as described above, attaching and adhering a light reflecting tape to a conventional product which has been conventionally used requires an extra manufacturing process and requires much labor. Not only is it cumbersome, it takes extra time and the production cost is high. Also, in this case, the reflective tape is often exposed to the outside, and if it was exposed, water droplets and dirt from rain would adhere, or the sticking surface would peel off during long use. Further, there is a problem that the original luminance cannot be maintained due to rubbing against the object or the surface thereof being damaged, and the reflection performance is remarkably reduced, so that the effect of calling attention cannot be sufficiently exerted.

This kind of long strip is formed by integrally molding two layers of a colored resin layer and a transparent resin layer, and has a cavity between the colored resin layer and the transparent resin layer along the longitudinal direction thereof. It is not known that a strip is formed and a strip-shaped light reflection tape whose reflection surface is on the transparent resin layer side is inserted through the hollow strip. However, it is conceivable that a strip-shaped light reflection tape having a reflection surface on the transparent resin layer side is interposed between the colored resin layer and the transparent resin layer along the longitudinal direction and is integrally formed by extrusion molding. When the reflection surface of the reflection tape is covered with the molten resin, there is a problem that the reflection performance is reduced as compared with the case where the reflection surface is covered with the air layer.

Accordingly, the present invention has been made to solve the above-mentioned problems, and can be used as a base material for bands as it is, and can be formed more easily and inexpensively as compared with conventional ones. An object of the present invention is to provide a belt-like base material provided with a light-reflecting tape that can withstand, maintain the original luminance, and sufficiently exhibit a caution effect.

[0007]

In order to achieve the above object, a belt-like base material containing a light reflecting tape according to the present invention has a belt-like shape in which two layers of a colored resin layer and a transparent resin layer are formed by integral molding. A base material, wherein a band-shaped light reflection portion is formed between the colored resin layer and the transparent resin layer along the longitudinal direction thereof, and a reflection surface is formed in the cavity line portion with a reflection surface on the side of the transparent resin layer. The tape was inserted.

[0008] As described above, the light reflecting tape is inserted into the hollow strip formed between the colored resin layer and the transparent resin layer, which is a band-shaped base material. Since the product is completed, the molding of the product is extremely simple, the production time can be shortened, and the production cost can be reduced.

Also, in use, since the light reflecting tape is inserted into the hollow strip and covered with the transparent resin layer, the reflecting surface of the light reflecting tape is not damaged even if it is rubbed or hit with an object. In addition, the original brightness can always be maintained, and the effect of alerting can be sufficiently exhibited. In addition, in this case, a slight gap between the air layer is formed between the reflection surface of the light reflection tape and the inner surface of the transparent resin layer, so that the reflection performance is reduced due to the relationship between the refractive index and the reflectance of light. There is no.

It is preferable that a reinforcing wire is embedded in the colored resin layer along the longitudinal direction. This can prevent unnecessary elongation of the band-shaped base material, and also prevent the risk that the light reflecting tape is broken.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a band-shaped base material (hereinafter, simply referred to as a band-shaped base material) provided with a light reflecting tape according to the present invention will be described below with reference to the drawings. 1 is a cutaway perspective view showing a part of the band-shaped base material, FIG. 2 is a cutaway plan view of the same part, and FIG. 3 is an enlarged sectional view taken along the line XX. In the figure, reference numeral 1 denotes a band-shaped base material, which comprises a colored resin layer 2 and a transparent resin layer 3 formed on one side of the colored resin layer 2. The two layers of the colored resin layer 2 and the transparent resin layer 3 are made of, for example, a polyurethane resin, and are simultaneously formed integrally by extrusion molding to be described later, and are formed into a long strip shape. The material of the band-shaped base material 1 may be another material such as a PVC resin or an EVA resin, and a flexible resin is selected.

The colored resin layer 2 and the transparent resin layer 3
A hollow strip 4 is formed along the center in the longitudinal direction, and a strip-shaped light reflecting tape 5 whose reflective surface is on the transparent resin layer 3 side is inserted into the hollow strip 4. . The light reflection tape 5 is a so-called glass bead type retroreflection tape in which a coating layer made of a reflector such as glass powder and a synthetic resin is formed on a base cloth such as a woven cloth or a nonwoven cloth. It has substantially the same width as the width of the ridge 4. In addition, although being molded at the same time as the colored resin layer 2 and the transparent resin layer 3, the transparent resin does not weld to the reflection surface 5 a of the light reflection tape 5, and the transparent resin layer An air layer is formed between the inner surface 3a of the light reflecting tape 3 and the reflecting surface 5a of the light reflecting tape 5. Thus, high brightness is maintained by the formation of the air layer.

Next, a brief description will be given of a method of manufacturing the band-shaped base material 1. FIG. 6 shows a schematic side cross section of the die 6 at the extruder tip. The die 6 is provided with a second supply pipe 8 for supplying a transparent resin T which is heated and melted similarly to the first supply pipe 7 for supplying a colored resin C which is heated and melted.
Are respectively arranged. The outlets 7a and 8a of the first and second supply pipes 7 and 8 are adjacent to each other at a lower position and an upper position, respectively, and further toward one end, and communicate with the first and second supply pipes 7 and 8. A tube 9 is provided continuously. As a result, the molten resins C and T merge at the outlets 7a and 8a and are discharged in two layers.

Outlets 7a, 8 of the first and second supply pipes 7, 8
The insertion port 10 which communicates with the discharge pipe 9 is provided between a, and the two layers of both resins C and C are inserted into the discharge pipe 9 from the insertion port 10.
The light reflection tape 5 is introduced together with the discharge of T. At the same time, a predetermined amount of air is supplied from the insertion port 10 into the discharge pipe 9 per unit time. Thus, the two layers of the resins C and T extruded from the die 6 are cooled by a cooling water tank (not shown).
And solidified by cooling. Thereby, as shown in FIG. 3, the two layers of the colored resin layer 2 and the transparent resin layer 3 are formed by integral molding, and between the colored resin layer 2 and the transparent resin layer 3 along the longitudinal direction. A hollow strip 4 is formed. Then, the band-shaped light reflection tape 5 having the reflection surface 5a on the side of the transparent resin layer 3 is inserted into the hollow strip portion 4.

The band-like base material 1a shown in FIGS. 4 and 5 is related to another embodiment, and the structure is substantially the same as that of the present embodiment. Detailed explanation is omitted. That is, two reinforcing wires 11 made of, for example, glass fiber are embedded in the colored resin layer 2 along the longitudinal direction. This is to prevent unnecessary elongation depending on the method of use since the band-shaped base material 1a is made of a synthetic resin. The reinforcing wire 11 may be made of metal instead of glass fiber, and the number thereof may be one, three or more as necessary.

The band-like base material 1 thus formed
1a is usually taken up by a predetermined length, packed and shipped. It is then delivered to manufacturers of bands such as water bottle shoulder bands, trouser bands, watch bands, school bag front bands, mobile phone hanging bands, dog collars, etc., where they are fastened as necessary. Accessories such as gold are attached and used as a band. The color of the colored resin layer 2 is selected depending on the product in which the band is used.

Therefore, the strip-shaped base material 1, 1a according to the present invention is used.
When used as a shoulder band of a water bottle, for example, when walking at night, since the light reflecting tape 5 is inserted into the hollow strip 4 formed between the colored resin layer 2 and the transparent resin layer 3 For example, when a light from a car or the like hits the vehicle, the light is clearly reflected to call attention to the driver, thereby preventing a traffic accident. In addition, since the reflection tape 5 is completely protected by the transparent resin layer 3, the reflection surface 5a of the light reflection tape 5 is not damaged even if it is rubbed or hit by an object, and the original high brightness is maintained. The effect of alerting can be fully demonstrated. Further, since the light reflecting tape 5 has a width smaller than the width of the band-shaped base materials 1 and 1a and is seen as one stripe, the light reflection tape 5 is attached so as to cover an entire side surface of the band-shaped base materials 1 and 1a. Excellent in design and high in commercial value.

In the present invention, the light reflecting tape 5
Although the reflective surface is mainly of a glass bead type, it is needless to say that a prism type and a further reflective tape may be used.

[0019]

As described above, the strip-shaped base material according to the present invention has a cavity in which two layers of a colored resin layer and a transparent resin layer are formed by integral molding, and between which a cavity is formed along the longitudinal direction. It is a new configuration in which a strip-shaped light reflection tape with the reflection surface as the transparent resin layer side is inserted in the strip, and it can be used as it is as a base material of various bands,
Various kinds of bands including such a light reflection tape can be formed more easily than before, and the production cost can be reduced. Furthermore, since the strip-shaped light reflection tape is completely covered and protected by the transparent resin layer, the reflection surface of the light reflection tape is not damaged even when rubbed or hit with an object during use, and the original high brightness And the effect of alerting can be sufficiently exhibited.

If the reinforcing wire is buried in the colored resin layer along the longitudinal direction, unnecessary elongation of the band-shaped base material can be prevented, thereby causing a risk that the light reflecting tape is broken. Is also prevented, and there is an effect that it can sufficiently withstand long-term use.
