Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a carrying bag used for a carrying bag.

[0002]

2. Description of the Related Art A string is often used as a carrying hand of a carrying bag. Conventionally, the end of the carrying bag is passed through a string passing hole of the carrying bag, and the end is used as a knot to thread the string portion and the carrying bag. It is thicker than the hole. As a result, the end of the carrier will not come out of the string hole.

It takes time and effort to tie the end of the cord into a knot, and the knot becomes thicker.
It is performed in advance to provide a T-shape by providing a stopper at the end of the cord, which is longer than the width of the cord or the cord passage hole of the handbag. Japanese Utility Model Application Laid-Open No. 48-20814 discloses a stopper provided with a short bar made of wood or synthetic resin at the end of a hand with a cord. Further, Japanese Utility Model Publication No. 62-35400 discloses a long and thin shape obtained by rigidly fixing a rope body made of a synthetic resin film and a rope made of a synthetic resin film and cutting the rope to a predetermined length. , And the ends of the cord body are welded to the longitudinal center of the hook body to form "T" -shaped cord locking portions at both ends of the cord body.

Further, in Japanese Unexamined Patent Publication (Kokai) No. 63-222705, a strap and stoppers at both ends thereof are used. The stopper is a synthetic resin having a width longer than a through hole of a carrying bag in at least one place. As a carrying method for carrying a bag, which is characterized by being integrally molded with a string, as a method of manufacturing the carrying bag, a mold hole having a stopper shape is used.
It is provided with a slight interval, and the string is supplied into this mold, injection molding of synthetic resin is performed in the mold hole, the molded product is taken out from the mold, and finally the string is integrally molded. It is described that a stopper is formed by cutting between two different resins.

FIG. 9 is a perspective view showing a state of use of the handbag thus manufactured. In the figure, reference numeral 1 is a handbag bag such as a paper bag. In the handbag bag 1, a through hole 2 is near the edge of the upper end opening. Two of them are provided at appropriate intervals. And the hand 3
As described above, the string 4 is made of cloth or synthetic resin, and the rib-shaped stopper 5 is provided at the end of the string 4 and is attached so as to sandwich the string 4.

The cord 4 with the stopper 5 is used by passing the stopper 5 through the through hole 2 in the upper part of the carrying bag 1. However, when passing through the through hole 2, the stopper 5 is slanted and can be passed therethrough. After passing, since the width of the stopper 5 is larger than the diameter of the through hole 2, the string 4 does not fall out.

[0007]

However, the above-mentioned Japanese Patent Laid-Open No.
In the manufacturing method of the handle in Japanese Patent Laid-Open No. 3-222705, there are two independent mold holes each having a stopper shape,
Each must be injection molded of synthetic resin.
Further, the stopper is formed by cutting between the two resins integrally formed on the cord, and the obtained handle has a portion near the cut portion of the cord on the outside of the stopper. In the outer portion, the fibers are likely to come off from the cut surface, resulting in poor appearance.

The object of the present invention is to eliminate the disadvantages of the conventional example, and to form a synthetic resin stopper having a width longer than the through hole of the handbag in the end portion of the cord to be the handbag for the handbag. A stopper can be obtained with a single mold hole, which simplifies the molding process, and provides a method for manufacturing a carrying bag carrying bag that makes the resulting carrying bag look good without the possibility of the cut points of the cord coming apart. To do.

[0009]

According to the present invention, in order to achieve the above object, a bar-shaped synthetic resin having a length which protrudes from the width of the cord is inserted into the die hole of the mold and protrudes from the width of the cord. In the case where the stopper is provided by die molding, the mold hole is provided with a space for a bar-shaped stopper close to each other, and a communication portion that secures a small space for enclosing each space around the peripheral surface of the cord. 1 is a substantially H-shaped mold cavity that is communicated with the mold cavity. After the synthetic resin is injection-molded into the mold cavity, the center of the portion formed by the communication section of the synthetic resin molded body by the mold cavity is The gist of the present invention is to cut it together with a string and divide a projecting piece that wraps the end of the string that is exposed to the outside into two integrally formed stoppers made of synthetic resin.

[0010]

According to the present invention, when two stoppers provided at the end of the carrying hand are simultaneously molded, they can be obtained by one continuous mold hole, and the molding process can be simplified. Further, in the obtained product, since the projecting piece integrated with the stopper covers the vicinity of the cut portion of the string which is outside the stopper, there is no possibility that the string in this part will come apart.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 and FIG. 2 are a vertical sectional side view and a plan view showing a first embodiment of the manufacturing method of the carrying bag for carrying bag of the present invention.

In the figure, 7 is a mold, but in the present invention, as in the case of the conventional example, a string 4 is inserted into the mold hole 6 of the mold 7, and the length of the string 4 protruding from the width thereof is greater than the width of the string. The synthetic resin bar-shaped stopper 5 is provided by die molding.

According to the present invention, the mold hole 6 through which the cord 4 is inserted is provided with the voids 8 and 8 which are portions to be the bar-shaped stopper 5 close to each other, and these voids 8 and 8 only surround the circumferential surface of the cord. Is a single H-shaped mold hole that is communicated with a communication portion 9 that secures a small space. The cord 4 is a flat cord in the illustrated case, and the material may be synthetic resin such as cloth or acrylic, or the like. .

In this way, when the string 4 is set in the mold 7 and the synthetic resin is injection-molded in the mold hole 6, the resin is filled in the cavities 8, 8 and the communicating portion 9, and after molding, When the string 4 is taken out, as shown in FIG. 2, the bar-shaped stopper 5 formed by the cavities 8 and 8 and the connecting portion 10 formed by the communicating portion 9 are formed.
As a result, a synthetic resin molded body is integrally formed on the outer circumference of the cord 4. The synthetic resin is not particularly limited as long as it can be injection-molded, and polyethylene, polypropylene, nylon, acetal or the like can be used. Particularly when the string 4 is an acrylic string, nylon resin or PPT is suitable as the synthetic resin for injection molding.

Next, in the synthetic resin molded body, the center of the connecting portion 10 is cut together with the inner cord 4 to divide into two synthetic resin stoppers 5. In the figure, a indicates a cut portion.

As shown in FIGS. 3 and 4, the obtained product is composed of a cord 4 and a bar stopper 5 made of synthetic resin which is attached to the end of the cord 4 so as to sandwich the cord 4 therein.
The half of the connecting portion 10 is integrally formed as a projecting piece 11, and the projecting piece 11 encloses the cord 4 extending outward from the stopper 5.

In the illustrated example, the projecting piece 11 has a cylindrical shape so as to surround the entire circumference of the string 4, but as another embodiment, the projecting piece 11 is composed of two upper and lower parallel pieces. The flat string 4 may be covered so as to sandwich both sides.

FIGS. 5 to 8 show a second embodiment of the present invention, in which a round cord woven in a rope shape is used as the cord 4 '. The manufacturing method and the prepared handle are almost the same as those in the first embodiment, but in this case, the projecting piece 11 that wraps around the end of the string 4 ′ extending from the stopper 5 to the outside is a tube so as to surround the entire circumference of the string 4. A shape is preferable.

[0019]

As described above, according to the method of manufacturing a carrying bag for a carrying bag of the present invention, a synthetic resin stopper having a width longer than the through hole of the carrying bag is formed at the end of the cord serving as the carrying bag carrying bag. In addition, two stoppers can be obtained with one mold hole, the molding process can be simplified, and the obtained handle has a good appearance without the possibility of the cord breaking apart because the cut portion of the cord is set inside the stopper. It will be something.
