[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 provided with a shape-retaining or portable band, the band being formed of a synthetic resin containing a light-reflecting tape. By doing so, the present invention relates to bags that can facilitate traffic safety and production.

[0002]

2. Description of the Related Art Conventionally, in order to prevent an elementary school student from accidental traffic accidents such as when going to and from school, various measures have been taken to the school bag that an elementary school student carries on his back in order to call attention to the driver of an automobile or the like. Has been done. For example, a means such as covering the cover lid with a cloth colored entirely in yellow, or adhering circular fluorescent tape to both side surfaces of the cover lid or the housing portion is adopted. However, this type of school bag is used for a long period of six years, and since it is a child and tends to be handled messyly, the yellow cloth or fluorescent tape is damaged during that time and the effect of the original attention is given. 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 reflection tape to a portable shoulder strap. More specifically, the shoulder strap is usually covered with a cushion material between a surface material such as leather and a lining material. However, a window hole is provided at 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 having a transparent sheet overlaid on the outer surface side between them, and the transparent sheet and the light reflecting tape are sewn together at the time of stitching the front material and the lining.

[0004]

However, in the structure in which the light reflecting tape is covered with the transparent sheet as described above, the light reflecting tape is rubbed and damaged even if the school bag is handled roughly. However, it is a shoulder strap that has been used for a long time, and a window hole is provided in a predetermined part of the outer material of the shoulder band, and a transparent sheet is laminated on the outer surface between the outer material of the window part and the cushioning material. In addition to accommodating the tape, an extra and troublesome operation is required as compared with a normal operation of sewing the transparent sheet and the light-reflecting tape together when sewing the front material and the lining material.

Therefore, there is a problem in that the manufacturing process is complicated, the labor is troublesome, and extra time is required, resulting in a high manufacturing cost. Further, in this case, since the window is opened, the appearance is not good and the design is inferior, and the product value cannot be increased. This means that the so-called front band that is attached to the school bag so as to surround both sides and the front surface of the accommodation part, and other bags, such as handbags and trunks, are used for shape retention or portable use. The same can be said for the band.

Therefore, the present invention has been made in view of the above problems, and is a bag provided with a shape-retaining or portable band, wherein the band is integrally molded of a synthetic resin containing a light-reflecting tape. An object of the present invention is to provide a bag which can be manufactured by molding so that traffic safety and simplification of manufacturing can be achieved.

[0007]

In order to achieve the above object, the bag according to the present invention is a bag provided with a shape-retaining or portable band, the band being transparent with a colored resin layer. The two layers, the resin layer and the resin layer, are simultaneously integrated by extrusion molding.
Formed into the strip, the colored resin layer and the cavity ridges along its longitudinal direction between the transparent resin layer is formed, is in the cavity ridges the reflecting surface and the transparent resin layer side and the on the reflecting surface Transparent
The resin of the resin layer is not welded, and the band-shaped light reflecting tape is inserted.

As the light reflecting tape, for example, a glass bead type in which a coating layer made of a reflector such as glass powder and a synthetic resin is formed in a sheet shape on the reflecting surface, or a very small pyramid prism is used. There is a prism type formed in a sheet shape, but the glass bead type is preferable.

As described above, the band is formed by integrally molding the two layers of the colored resin layer and the transparent resin layer, and the light reflecting tape is inserted into the cavity formed between the colored resin layer and the transparent resin layer. Since it has the above structure, it can be used as a product as it is, 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 strips 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 by an object. , The original brightness is always maintained and the effect of alerting can be fully exerted, which ensures the safety of traffic. Moreover, in this case, since a slight air gap is formed between the reflecting surface of the light reflecting tape and the inner surface of the transparent resin layer, the reflecting performance is not deteriorated.

It is preferable that a reinforcing wire is embedded in the colored resin layer along the longitudinal direction thereof. As a result, it is possible to prevent the band from being unnecessarily stretched, and also to prevent the risk that the light reflecting tape is broken.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a bag according to the present invention will be described below with reference to the drawings. In addition, in the present embodiment, the front band of the bag, which is a bag, will be described, but the present invention is not limited to this. For example, a bag such as a handbag or a trunk for shape retention or portable use. Of course, it can be applied to the band. The school bag is made by using cowhide or synthetic leather and sewing.

In the figure, reference numeral 1 is a housing portion for housing 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 and the gusset 5
It is formed in a substantially box-like shape having an opening 6 on the upper surface.
Small compartments 1a and 1b divided into front and rear by a partition plate 7 on the front side of the storage section 1 and a pocket section 10 capable of opening and closing the upper opening 8 with a fastener 9 on the front side are provided, and articles such as small articles can be stored therein. I am trying.

Reference numeral 11 denotes a cover which 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 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. Thirteen
Reference numeral a denotes a pair of portable shoulder straps whose base end is attached to the upper center of the back plate 2, and a plurality of adjustment holes 14 are provided in the front end side. On the other hand, on the bottom plate 4, shoulder straps 13b paired with the shoulder straps 13a are attached to both sides of the bottom plate 4, and the buckles 15 are inserted and locked at the tips of the shoulder straps 13b. Is installed. A name tag accommodating portion 1 having a front opening 16 for inserting a name tag on the front surface of the pocket portion 10.
7 is provided.

Reference numeral 18 denotes a pair of left and right front bands which are mounted so as to surround both side surfaces of the gusset skin 5 and the front surface of the pocket portion 10. The front band 18 is a band body 19
Comprises a colored resin layer 19a and a transparent resin layer 19b formed on one side surface 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 molded at the same time by extrusion molding, which will be described later, and are formed into a long strip shape. The material of the band body 19 may be other material such as PVC resin or 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 mounted. In the case of the present invention, if the color of the school bag is red, the same red color is used. 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 single hollow strip 20 is formed between the colored resin layer 19a and the transparent resin layer 19b along the longitudinal center thereof, and a reflective surface is provided in the hollow strip 20 with a transparent resin layer. The strip-shaped light reflection tape 21 on the 19b side is inserted. The light reflecting tape 21 is a so-called glass bead type retroreflective tape in which a coating layer composed of a reflector such as glass powder and a synthetic resin is formed on a base cloth such as a woven cloth or a non-woven cloth, and is a cavity to be formed. It has a width substantially the same as the width of the strip portion 20. Moreover, although the colored resin layer 19a and the transparent resin layer 19b are molded at the same time, the transparent resin is not welded to the reflection surface 21a of the light reflection tape 21, and the transparent resin layer is formed in the hollow strip portion 20. An air layer is formed between the inner surface 22 of 19b and the reflecting surface 21a of the light reflecting tape 21. Thus, the formation of the air layer maintains high brightness.

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

Outlet 24 of the first and second supply pipes 24, 25
An insertion port 27 communicating with the discharge pipe 26 is provided between a and 25a, and the light reflection tape 21 is introduced into the discharge pipe 26 through the insertion port 27 together with the discharge of the two layers of the resins C and T. It 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 manner, the two layers of the resins C and T extruded from the die 23 are passed through a cooling water tank (not shown) to be cooled and solidified. As a result, as shown in FIG. 3, the two layers of the colored resin layer 19a and the transparent resin layer 19b are integrally molded, and the colored resin layer 19a and the transparent resin layer 1 are formed.
A cavity strip portion 20 is formed between the strip portion 9b and 9b along the longitudinal direction thereof. Then, the strip-shaped light-reflecting tape 21 having the reflecting surface 21a on the transparent resin layer 19b side is inserted into the cavity 20.

As shown in FIG. 2, a pair of band bodies 19, 19 cut into a predetermined length is attached with a buckle 30 by attaching a folded portion 28 to one end of one of the band bodies 19 with eyelets 29. To be Further, a clasp 31 is attached to one end of the other band body 19 and a plurality of adjustment holes 32 are provided in a row at one end. Reference numeral 33 is a mounting hole provided on the multi-end side of each band body 19, 19. In this way, the pair of front bands 18 (18a, 18b) are molded.

The other ends of the front bands 18a and 18b are sewn together with the outer edge of the back plate portion 2 and the accommodating portion 1 by the edging 34 when they are sewn together, and are sewn at the same time. The eyelet 29 is attached to the frame 5 through the mounting hole 33. In addition, a through hole 35 formed in the front surface of the pocket portion 10
The front band 18 (18a, 18b) is attached to the front band 18 by inserting the same into the front band 18 and connecting each end portion with the buckle 30.

In the school bag according to the present invention, since the light reflection tape 21 is inserted into the hollow strip portion 20 formed between the colored resin layer 19a and the transparent resin layer 19b, it is possible to walk at night. When the car is hit by a light such as a car, 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 light reflection tape 2 can be rubbed or hit by an object.
The first reflecting surface 21a is not damaged, the original high brightness is maintained, and the effect of calling attention can be sufficiently exerted. Further, since the width of the light reflection tape 21 is narrower than the width of the band body 19 and can be seen as one stripe, it is superior in design as compared with the one mounted so as to cover one side surface as a whole. Is high.

The front band 181 (1 shown in FIGS. 4 and 5
81a, 181b) relates to another embodiment, and the configuration thereof is substantially the same as that of the present embodiment, and therefore, the same parts will be denoted by the same reference numerals and detailed description thereof will be 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 of the colored resin layer 19a. 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 of the reinforcing wire 36 may be one or three or more as required.

As described above, according to the present invention, when the outer skin and the inner skin are originally formed by sewing, the synthetic resin can be easily formed by extrusion molding, and the eyelets 29 can be easily installed. In addition, the colored resin layer 1 is used for the color of the bag to be attached.
It can be easily dealt with by simply changing the color of 9a, and the change can be freely performed. In the present invention, the light reflecting tape 5 is mainly of the glass beads type as the reflecting surface, but it is needless to say that a prism type or other reflecting tape may be used.

[0024]

As described above, in the bag according to the present invention, the band is formed by integral molding of 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 hollow strip to be molded, it can be used as it is as a product, simplifying the production of bags and reducing the production cost.

In use, since the light-reflecting tape is inserted into the hollow strips 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 by an object. It can be used for a long time. In addition, the original brightness can always be maintained, and the effect of calling attention can be fully exerted, which ensures sufficient traffic safety.
Moreover, in this case, since a slight air gap is formed between the reflecting surface of the light reflecting tape and the inner surface of the transparent resin layer, the reflecting performance is not deteriorated.

Furthermore, since the band is formed by extrusion molding of synthetic resin, it is standardized and easy to manage, and
Since the light-reflecting tape is also a stripe type, it is excellent in terms of design and enhances commercial value.

Furthermore, by embedding a reinforcing wire in the colored resin layer along its longitudinal direction, unnecessary elongation of the band can be prevented, and there is a risk that the light reflecting tape will be broken. It has the effect of being prevented and capable of withstanding long-term use.
