Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag such as a handbag, a school bag, or a trunk equipped with a band, which can contribute to traffic safety by providing the band with a light reflection function. .

[0002]

2. Description of the Related Art Among the bags, the school bag that elementary school students carry is equipped with various measures to alert drivers such as automobiles to prevent accidents such as accidents when going to or from school. ing. For example, means such as attaching a yellow cloth to the cover of the school bag or attaching a circular fluorescent tape to both sides of the cover or the accommodating portion is adopted.
However, the school bag is used for a long period of six years,
Moreover, since it is liable to be handled roughly, the yellow cloth or the fluorescent tape may be damaged during that time, and the original effect of calling attention may not be sufficiently exerted.

On the other hand, when the light reflecting tape is integrally sewn to the shoulder strap, a cushion material is usually wrapped between the outer material such as leather and the lining material, and a window hole is provided at a predetermined portion of the outer material to form a window. A light-reflecting tape having a transparent sheet laminated on the outer surface was housed between the outer material of the hole and the cushioning material, and the transparent sheet and the light-reflective tape were sewn together at the time of stitching the outer material and the lining.

[0004]

However, in the band in which the light reflection tape is covered with the transparent sheet, the light reflection tape will not be rubbed and damaged even if the school bag is handled in a disorderly manner. , A window hole is provided in a predetermined portion of the outer material, and a light reflecting tape having a transparent sheet laminated on the outer surface is housed between the outer material of the window material portion and the cushion material, and the transparent sheet is used when the outer material and the lining material are sewn together. Compared with the usual work such as stitching and the light reflection tape at the same time, an extra and troublesome work is forced.

Therefore, there is a problem that the manufacturing process of the band becomes complicated, the labor is troublesome, and extra time is required, so that the manufacturing cost becomes high. In addition, since the windows are opened, the appearance is not good, the design is inferior, and the product value cannot be increased. This also applies to a front band that is attached so as to surround both side surfaces and a front surface of a housing portion in a school bag, a shape-retaining band that is used by being placed in a handbag, a trunk, or the like, or a portable band.

In order to solve the conventional problems, the inventor of the present application first forms a band into a two-layer structure of a colored resin layer and a transparent resin layer, and extends the length between the colored resin layer and the transparent resin layer. Patent application 2000
Filed as -363744. But part of the band,
In particular, there was a problem in that the reflection dropped at the bent portion toward the back side. Upon investigating the cause, the space provided between the colored resin layer and the transparent resin layer is a gap that cannot be measured by a general measuring instrument, so it may come into contact with the temperature change or bend. It has been clarified that it occurs when the space portion is crushed and abutted against each other.

Therefore, the present invention has been made in view of the above problems, and in a bag provided with a band, the band always reflects light regardless of the outside air temperature or the usage condition, and contributes to traffic safety. The purpose is to provide bags to be obtained.

[0008]

In order to achieve the above object, the bag according to the present invention has a band according to claim 1, wherein the band used for the bag has a two-layer structure of a colored resin layer and a transparent resin layer. , A space is provided in the longitudinal direction between the colored resin layer and the transparent resin layer, and the reflecting surface of the light reflecting tape is inserted into the space facing the transparent resin layer side, and the transparent resin for the light reflecting tape reflecting surface is formed. It is provided with a translucent resin portion that prevents the layers from coming into contact with each other. As a second aspect, in the bag according to the first aspect, a reinforcing wire material for preventing unnecessary extension of the band is embedded in the colored resin layer in the longitudinal direction.

As the light reflecting tape, for example, a glass bead type in which a coating layer of a reflector such as glass powder is formed on a sheet made of synthetic resin or the like, and a prism type in which a minimal pyramidal prism is attached to the sheet are used. However, glass beads are preferred. As the translucent resin part, a heat-resistant synthetic resin tape or heat-resistant synthetic resin film having translucency is used, and it is provided so as to overlap within the width of the light reflecting tape, or so as to overlap at an appropriate position of the width of the light reflecting tape. .

As described above, the band main body has a two-layer structure composed of the colored resin layer and the transparent resin layer, and a space is provided in the longitudinal direction between the colored resin layer and the transparent resin layer, and the light reflection tape is provided in the space. Since the light-transmissive resin portion prevents contact between the light-reflective tape reflection surface and the transparent resin layer, the reflective performance of the band does not deteriorate depending on the outside air temperature or the usage state. No, you can use it as it is,
It is possible to simplify the production of bags.

Since the light reflecting tape is in the space and is covered with the transparent resin layer through the transparent resin portion, the reflecting surface is not damaged even if it is rubbed or hit by an object, and the original brightness is always maintained. Maintain and fully exert the effect of alerting, thereby contributing to traffic safety.

In addition to the features of claim 1, the bag of claim 2 embeds a reinforcing wire along the longitudinal direction in the colored resin layer, thereby preventing unnecessary elongation of the band. In addition, it is possible to prevent breakage of the light reflecting tape or the transparent resin portion.

In the first embodiment of the front band 18, the band body 19 has a two-layer structure including a colored resin layer 19a and a transparent resin layer 19b, and the colored resin layer 19a and the transparent resin layer 19b are made of, for example, polyurethane resin, The extrusion molding, which will be described later, simultaneously forms an integral body, and also forms a long strip. The material of the band body 19 is PVC resin or EV.
Other resin such as A resin may be used, and a flexible resin is selected. The color of the colored resin layer 19a can be selected according to the color of the bag to be used, and for example, if the color of the school bag is red, it is the same red color. Similarly, the color of the light reflection tape 21 can be variously selected in consideration of the contrast with the color of the colored resin layer 19a and the like.

A single space 20 is formed along the longitudinal center between the colored resin layer 19a and the transparent resin layer 19b, and the reflection surface 21a of the light reflection tape 21 is provided in the space 20 on the transparent resin layer 19b side. And a transparent resin portion 22 for preventing the transparent resin layer 19b from coming into contact with the light reflecting tape reflecting surface 21a. The light reflection tape 21 is

It has approximately the same width. The light reflecting tape 21 is inserted when the colored resin layer 19a and the transparent resin layer 19b are formed. As shown in FIG. 3, the heat reflecting translucent resin is formed in the width middle portion, the width left and right, or the same width of the light reflecting tape reflecting surface 21a. Since the translucent resin portion 22 is provided between the transparent resin layer 19b and the light reflecting tape 21, the transparent resin layer 19b may be welded to the light reflecting tape reflecting surface 21a. Also, even if the outside air temperature rises or the usage pattern changes, the space portion 20 is maintained and high brightness is maintained.

Here, a method of manufacturing the band body 19 will be described with reference to FIG.
In brief, the first supply pipe 24 for supplying the heat-melted colored resin C to the die 23 attached to the tip of the extruder, and the transparent resin T similarly overheated and melted
Is provided so as to face the second supply pipe 25, and the outlets 24a, 25a of the first and second supply pipes 24, 25 are adjacent to each other, and the first and second supply pipes 24, 25 are provided ahead of them.
One discharge pipe 26 that communicates with the above is continuously provided. As a result, the two molten resins C and T are discharged from the outlets 24a,
It joins at 25a and can be extruded in a two-layer state.

First supply pipe outlet 24a and second supply pipe outlet 25
An insertion port 27 that communicates with the discharge pipe 26 is provided between the a and the a, and both resins C and T of two layers are extruded from the insertion port 27 into the discharge pipe 26. And will be introduced again. Almost at the same time, a predetermined amount of air is supplied from the insertion port 27 into the discharge pipe 26 per unit time to cool and solidify the two layers of the resins C and T extruded from the die 23. As a result, as shown in FIG. 2, the band body 19 having the two-layer structure of the colored resin layer 19a and the transparent resin layer 19b is integrally molded, and the longitudinal direction is provided between the colored resin layer 19a and the transparent resin layer 19b. The space portion 20 of the
The reflecting surface 21a of the light reflecting tape 21 is provided inside the transparent resin layer 19
The light-transmissive resin portion 22 is directed toward the b side and toward the reflecting surface 21a side.
Since they are inserted one after another, they are standardized and easy to manage.

A long band body 1 formed by the above means
9, a pair of band bodies 19a, 19b is cut, and one end of one of the band bodies 19a, 19b is folded back as shown in FIG.
The buckle 30 is attached by attaching 8 to the eyelet 29, and the clasp 31 is attached to one end of the other side band body 19b, and a plurality of adjustment holes 32 are provided in a row, and each band body 19a is attached. , 19B are provided with mounting holes 33 on the multi-end side and are used as a pair of front bands 18 (18a, 18b).

When the front bands 18a, 18b are attached to the bag, the outer peripheral edges of the back plate 2 and the housing 1 are integrally sewn together by the edging 34, and the front bands 1 are interposed therebetween.
The other ends of 8a and 18b are inserted and sewn at the same time, and eyelets 29 are attached to both gussets 5 through attachment holes 33. In addition, the front band 1 is inserted through the through hole 35 provided on the front surface of the pocket portion 10 and the respective one end portions are connected by the buckle 30.
8 (18a, 18b) is attached.

In the bag-type school bag according to the present invention, since the light reflection tape 21 is inserted into the space 20 formed between the colored resin insert 19a and the transparent resin layer 19b, it can be used at night. When the light of an automobile hits when walking, it will be clearly reflected and alert the driver.
It is possible to prevent traffic accidents. Further, since the reflection tape 21 is completely protected by the transparent resin layer 19b, the reflection surface 21a of the light reflection tape 21 is not damaged even if it is rubbed or hit by an object. In particular, since the translucent resin portion 22 is provided on the reflective surface 21a side, the band body 19
The reflective surface 21a and the transparent resin layer 19b do not come into contact with each other during molding, and the space portion 20 may be crushed even if the outside air temperature rises during use or the front band 18 curves to the back surface side. The original high brightness is maintained and the effect of alerting can be fully exerted. Further, since the width of the light reflection tape 21 is narrower than that of the band body 19 and can be seen as one stripe, it is superior in design and has a high commercial value as compared with the one mounted so as to cover the entire one side surface.

The second embodiment of the band used in the bag according to the present invention will be described in terms of differences from the first embodiment, and as shown in FIG. 5, the colored resin layer 19a is provided along the longitudinal direction thereof. For example, two reinforcing fibers 36 made of glass fiber are embedded on the left and right. This is because the band main body 19 is made of synthetic resin, so that unnecessary extension is prevented depending on the method of use. The reinforcing wire 36 may be made of metal other than glass fiber, and the number thereof may be one or three or more as required.

[0024]

[Examples] As described above, the front band used in the bag of the present invention is originally formed by sewing the outer skin and the back skin, and can be easily manufactured by extrusion molding of synthetic resin. Then, it can be easily attached by the eyelet 29. Further, the color of the colored resin layer 19a can be freely changed according to the color of the bag to be mounted. Although the glass beads type is mainly used for the reflecting surface 21a of the light reflecting tape 21, a prism type or other reflecting tape may be used. It is desirable to use a polyester film or a polyester sheet having translucency and heat resistance as the translucent resin portion 22, but the material is arbitrary as long as it is a resin having translucency, heat resistance and flexibility. .

The reason why the reflection increases due to the formation of the space 20 is that the light incident from the transparent resin layer 19b is repeatedly reflected between the light reflection tape 21 and the transparent resin layer 19b. In addition, the light reflection tape 21 and the transparent resin layer 19b
The reason why the reflection does not decrease even if the transparent resin portion 22 is interposed between the transparent resin layer 19b and the transparent resin layer 22 is considered to be because the reflectances of the transparent resin layer 19b and the transparent resin portion 22 are different. Also, it is considered that the central portion of the width of the transparent resin layer 19b swells due to the formation of the space portion 20 and the interposition of the translucent resin portion 22 to act as a lens.

[0026]

Since the bag according to the present invention is as described above, it has the following effects. The bag according to claim 1 is provided with a light-reflecting tape in the space between the colored resin layer and the transparent resin layer forming the band, and a translucent resin portion on the reflecting surface side of the light-reflecting tape. Therefore, the original brightness is always maintained without being affected by the outside temperature and the usage condition of the band,
The effect of alerting is fully exerted, which contributes to traffic safety. Moreover, the production of the bags can be simplified and the production cost can be reduced. Further, since the light reflecting tape is in the space and covered with the transparent resin layer, the reflecting power can be maintained for a long period of time.

According to the bag of claim 2, in addition to the effect of claim 1, since the reinforcing wire is embedded along the longitudinal direction in the colored resin layer, unnecessary elongation of the band can be prevented. it can. As a result, it is possible to prevent the light reflecting tape and the translucent resin portion from breaking and to be able to withstand long-term use sufficiently.
