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 having a shape-retaining or portable band, wherein the band is formed of a synthetic resin having a light reflecting tape inside. The present invention relates to bags that can achieve traffic safety and simplify production.

2. Description of the Related Art Conventionally, in order to prevent elementary school students from accidental traffic accidents when going to and from school, various measures have been taken on school bags to be carried by elementary school students on their backs to draw attention to drivers such as automobiles. Have been. For example, the cover is covered with a cloth colored yellow in its entirety, or a circular fluorescent tape is adhered to both sides of the cover or the housing. However, since this kind of school bag is used for a long period of six years, and is a child and tends to be treated in a mess, the yellow cloth or the fluorescent tape is damaged during that time, and the original effect of alerting There was a problem that it was not possible to fully demonstrate.

On the other hand, there is a means for integrally sewing a light reflecting tape to a portable shoulder band. More specifically, the shoulder band is usually covered with a cushion material between a surface material such as leather and a lining. A window hole is provided in a predetermined portion of the surface material, and the surface material of the window hole portion and the cushion material are provided. And a light reflecting tape on which a transparent sheet is superimposed on the outer surface side is accommodated, and the transparent sheet and the light reflecting tape are sewn together when the outer material and the lining are stitched.

[0004]

However, in such a structure in which the light reflecting tape is covered with the transparent sheet, the light reflecting tape may be rubbed and damaged even if the school bag is handled irregularly. Although it disappears, it is a shoulder band conventionally used, provided with a window hole in a predetermined portion of the surface material, and a light reflection in which a transparent sheet is overlapped on the outer surface side between the surface material of the window hole portion and the cushion material. In addition to storing the tape, when the outer material and the lining are sewn together, extra and cumbersome work is required as compared with a normal operation of suturing the transparent sheet and the light reflecting tape together.

[0005] For this reason, there is a problem that the manufacturing process is complicated, requires much time and requires extra time, and the manufacturing cost is increased. Further, in this case, since the window is opened, the appearance is poor, the design is inferior, and there is a problem that the commercial value cannot be enhanced. This means that the so-called front band which is attached to the school bag so as to surround both sides and the front surface of the accommodation portion, and for other bags, for example, handbags and trunks, for shape retention or portable use. The same can be said for the band.

The present invention has been made in view of the above problems, and is a bag comprising a shape-retaining or portable band, wherein the band is made of a synthetic resin integrally molded with a light reflecting tape. It is an object of the present invention to provide bags that can achieve traffic safety and simplification of production by being molded by using the above method.

[0007]

According to the present invention, there is provided a bag comprising a shape-retaining or portable band, the band comprising a colored resin layer and a transparent resin layer. It is molded by integral molding of two layers with a resin layer, and a hollow ridge is formed between the colored resin layer and the transparent resin layer along the longitudinal direction thereof. It has a configuration in which a band-shaped light reflection tape on the side is inserted.

As the light reflection tape, for example, a glass bead type in which a reflection layer such as glass powder and a coating layer made of a synthetic resin or the like are formed in a sheet shape, or a very small pyramid-shaped prism is used. Although there is a prism type formed in a sheet shape, the glass bead type is preferable.

As described above, the band is formed by integral molding of the two layers of the colored resin layer and the transparent resin layer, and the light reflecting tape is inserted into the hollow strip formed between the colored resin layer and the transparent resin layer. With such a configuration, it can be used as a product as it is, and the production of bags can be simplified and the production cost can be reduced.

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 is always maintained, and the effect of the alert can be sufficiently exerted, whereby the traffic safety is sufficiently ensured. Moreover, in this case, a slight gap between the air layers 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 does not decrease.

It is preferable that a reinforcing wire is embedded in the colored resin layer along the longitudinal direction. Thus, unnecessary elongation of the band can be prevented, and furthermore, the danger that the light reflecting tape is broken can be prevented.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a bag according to the present invention. In the present embodiment, the front band of the school bag, which is a bag, will be described. However, the present invention is not limited to this. It is needless to say that the present invention can also be applied to the band. The school bag is made of cowhide or synthetic leather and is manufactured by sewing.

In FIG. 1, reference numeral 1 denotes a storage section for storing school supplies such as textbooks and notebooks. The housing 1 is a back plate 2
The bottom and both sides between the front plate 3 and the bottom plate 4
The upper surface is formed in a substantially box shape having an opening 6.
Small compartments 1a and 1b, which are divided into front and rear by a partition plate 7, and a pocket 10 which can open and close an upper opening 8 with a zipper 9 are provided on the front side of the accommodation section 1 and can store small articles and the like. Like that.

A cover 11 is attached so as to openably and closably cover the opening 6 on the upper surface of the housing 1 and the entire surface of the pocket 10. A well-known locking tool 12 is attached to the tip of the cover 11 so that it can be detachably engaged with a locking tool (not shown) of the bottom plate 4. 13
Reference numeral a denotes a pair of portable shoulder straps whose base ends are attached to the upper center of the back plate portion 2, and a plurality of adjustment holes 14 are arranged in a row at the distal end side. On the other hand, a pair of shoulder bands 13b are attached to both sides of the bottom plate 4 to form a pair with the shoulder bands 13a. Is installed. A name tag storage unit 1 having an opening 16 at the front for inserting a name tag in the front of the pocket portion 10.
7 are provided.

Reference numeral 18 denotes a pair of left and right front bands attached so as to surround both side surfaces of the gusset 5 and the front surface of the pocket portion 10. The front band 18 includes a band body 19.
Comprises a colored resin layer 19a and a transparent resin layer 19b formed on one side of the colored resin layer 19a. The two layers of the colored resin layer 19a and the transparent resin layer 19b are made of, for example, a polyurethane resin, and are integrally formed at the same time by extrusion molding to be described later, and are formed into a long strip shape. The material of the band body 19 may be another material such as a PVC resin or an EVA resin, and a flexible resin is selected. The color of the colored resin layer 19a is selected according to the color of the bag to be worn. In the case of the present invention, if the color of the school bag is red, it is set to the same red color. Similarly, the color of the light reflecting tape 21 can be changed and variously selected in consideration of the contrast with the color of the colored resin layer 19a.

A hollow ridge 20 is formed between the colored resin layer 19a and the transparent resin layer 19b along the center in the longitudinal direction. A strip-shaped light reflection tape 21 on the 19b side is inserted. The light reflection tape 21 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 20. In addition, although it is formed simultaneously with the colored resin layer 19a and the transparent resin layer 19b, the transparent resin does not adhere to the reflection surface 21a of the light reflection tape 21, and the transparent resin layer An air layer is formed between the inner surface 22 of the light reflection tape 21 and the reflection surface 21a of the light reflection tape 21. Thus, high brightness is maintained by the formation of the air layer.

Here, a method of manufacturing the band body 19 will be briefly described. FIG. 6 shows a die 23 at the tip of the extruder.
1 shows a schematic side cross-section of FIG. The die 23 is provided with a first supply pipe 24 for supplying a colored resin C that is heated and melted.
Similarly, second supply pipes 25 for supplying the transparent resin T that is overheated and melted are provided. The outlets 24a, 25a of the first and second supply pipes 24, 25 are adjacent to each other at a lower position and an upper position, respectively, and further toward the tip end, a single discharge communicating with the first and second supply pipes 24, 25. A tube 26 is provided continuously. As a result, the molten resins C and T merge at the outlets 24a and 25a and are discharged in two layers.

The outlet 24 of the first and second supply pipes 24, 25
An insertion port 27 communicating with the discharge pipe 26 is provided between the discharge pipe 26 and the discharge pipe 26. You. At the same time, a predetermined amount of air is supplied from the insertion port 27 into the discharge pipe 26 per unit time. In this way, the two layers of the resins C and T extruded from the die 23 are passed through a cooling water tank (not shown) and cooled to be solidified. Thereby, as shown in FIG. 3, two layers of the colored resin layer 19a and the transparent resin layer 19b are formed by integral molding, and the colored resin layer 19a and the transparent resin layer 1 are formed.
9b is formed along the longitudinal direction with the hollow strip 20. Then, a band-shaped light reflection tape 21 having the reflection surface 21a on the side of the transparent resin layer 19b is inserted into the hollow strip portion 20.

As shown in FIG. 2, a buckle 30 is attached to a pair of band bodies 19, 19 cut to a predetermined length by attaching a folded portion 28 to one end of one of the band bodies 19 with an eyelet 29. Can be In addition, a clasp 31 is attached to one end of the other band main body 19, and a plurality of adjustment holes 32 are arranged in a row on one end side. 33 is a mounting hole provided on the multi-end side of each band body 19,19. Thus, a pair of front bands 18 (18a, 18b) are formed.

The other ends of the front bands 18a and 18b are inserted into the outer edges of the back plate 2 and the accommodating portion 1 when the outer peripheral edges are integrally sewn together by the edge decoration 34, and are simultaneously sewn. An eyelet 29 is attached to 5 through the mounting hole 33. Further, a through hole 35 formed in the front of the pocket portion 10 is provided.
The front bands 18 (18a, 18b) are mounted by inserting each end through a buckle 30.

In the school bag according to the present invention, since the light reflecting tape 21 is inserted into the hollow strip portion 20 formed between the colored resin layer 19a and the transparent resin layer 19b, walking is performed at night. When the light of a car hits, such as when you do, it will be clearly reflected and call attention to the driver,
Traffic accidents can be prevented beforehand. Further, since the reflection tape 21 is completely protected by the transparent resin layer 19b, even if the reflection tape 21 rubs against an object,
The first reflective surface 21a is not damaged, the original high luminance is maintained, and the effect of alerting can be sufficiently exhibited. Further, since the light reflecting tape 21 has a width smaller than the width of the band body 19 and is seen as one stripe, the light reflecting tape 21 is superior in design in comparison with a tape that can be attached so as to cover the entire side surface, and has a commercial value. Is high.

The front band 181 (1) shown in FIGS.
81a and 181b) relate to other embodiments, and the configuration is substantially the same as that of the present embodiment. Therefore, the same portions are denoted by the same reference numerals and detailed description is omitted. That is, two reinforcing wires 36 made of, for example, glass fiber are embedded in the colored resin layer 19a along the longitudinal direction. This is to prevent unnecessary elongation of the band body 19 depending on the method of use since the band body 19 is made of synthetic resin. The reinforcing wire 36 may be made of metal instead of glass fiber, and the number thereof may be one, three or more as necessary.

As described above, according to the present invention, where the skin and the back skin are sewn and formed, it can be easily formed by extrusion of synthetic resin, and can be easily mounted by the eyelet 29. In addition, the colored resin layer 1
It can be easily dealt with simply by changing the color of 9a, and the change can be made freely. In the present invention, the light reflecting tape 5 is mainly made of a glass bead type having a reflecting surface, but it is needless to say that a prism type or another reflecting tape may be used.

[0024]

As described above, in the bag according to the present invention, the band is formed by integrally molding the two layers of the colored resin layer and the transparent resin layer, and the band is formed between the colored resin layer and the transparent resin layer. Since the light reflecting tape is inserted into the formed hollow strip, it can be used as a product as it is, and the production of bags can be simplified and the production cost can be reduced.

In use, since the light reflecting tape is inserted into the hollow strip and is 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. , Long-term use is possible. In addition, the original brightness can always be maintained, and the effect of alerting can be sufficiently exerted, thereby sufficiently securing traffic safety.
Moreover, in this case, a slight gap between the air layers 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 does not decrease.

Further, since the band is formed by extrusion molding of synthetic resin, standardization is achieved and management is easy.
Since the light reflection tape is also a stripe type, it is excellent in design and product value is enhanced.

Furthermore, if a reinforcing wire is buried in the colored resin layer along the longitudinal direction, unnecessary elongation of the band can be prevented, and there is a danger that the light reflecting tape may be broken. This has the effect that it can be prevented and can withstand long-term use.
