Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a handle string for a handbag such as a handbag.

[Conventional technology]

As a handle string for such a bag, a rope formed by appropriately bundling synthetic resin raw materials (threads) such as polypropylene and twisted together is used. Installed on.

FIG. 8 is a front view showing a conventional device for cutting such a synthetic resin rope into a length of a hand rope. A Nikumuro wire 12 is stretched between the columns 11 and 11 to cut the rope. Is the ninth
As shown in FIG. 10 and FIG. 10, the nichrome wire is heated, and the synthetic resin rope 13 is positioned above the nichrome wire 12 in a direction orthogonal to the nichrome wire 12, and then the rope 13 is lowered to the nichrome wire 12. The rope 13 was cut by the heat of the nichrome wire 12 applied at a right angle.

The rope 13 of the handle string length thus obtained has a cut 14 at a right angle to the length direction of the rope 13 as shown in FIG.
The end faces of the cut ends are in a state in which the raw fabrics (threads) are welded to each other by the heat of the nichrome wire 12.

Then, as shown in FIG. 12, the rope 13 having the length of the handle string is inserted into the string passing hole 6 formed in the upper portion of the handbag paper bag 5, and both ends of the rope 13 are projected to the inside of the paper bag 5, A knotted hump 7 is formed by tying the projecting portion together (stop knotting) so that both ends of the rope 13 do not come out from the string passing hole 6 to form a handle string 15.

[Problems to be solved by the device]

However, with a hand-held cord with the cut formed at a right angle,
Since the area of the cut is only the thickness of the rope, the raw fabric (thread) will be welded in this small area, which may cause the raw fabric (thread) to come apart, which affects the knot. There is a risk that the knot will be broken.

Further, since the rope is inserted into the cord insertion hole from the cut portion cut at a right angle, the peripheral edge of the cut portion may be caught in the cord insertion hole, and it may be difficult to insert the rope.

An object of the present invention is to provide a handle strap for a carrying bag which solves the inconvenience of the conventional example, can be used without anxiety that the cut ends may not be scattered, and can be smoothly inserted into the strap hole of a paper bag. It is in.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention cuts a synthetic resin rope with a cutting blade with a heater formed with a large acute angle, and cuts the cut from the thickness of the rope diagonal to the length direction of the rope. Also formed into an elliptical shape with a large area,
Further, the gist is that the cut surface is welded and hardened.

[Action]

According to the present invention, since the synthetic resin rope is cut by the cutting blade whose tip is formed with a large acute angle, the cut end is formed obliquely and becomes a large elliptical shape.

Further, since the cutting blade is equipped with a heater, the cut end is welded at the same time when cutting, and it is welded over a wide area, so that the raw fabric (thread) is less likely to come apart. Furthermore, since the tip of the cut end is tapered, the rope can be smoothly inserted into the string passage hole of the paper bag.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view showing an embodiment of a hand strap for a handbag according to the present invention. The hand strap 1 uses a rope in which raw materials (threads) made of synthetic resin such as polypropylene are appropriately bundled and twisted. The cuts 2a and 2b at both ends are formed obliquely with respect to the length direction of the rope.

2 to 4 are explanatory views showing a process for obtaining such a handle string 1, in which 3 is a rope cutting blade, and the cutting blade 3 has a sharp tip formed at both ends of the tip portion. Are tapered surfaces 3a and 3b, and the cutting blade 3 is equipped with a heater.

Below the cutting blade 3, a rope 4 made of synthetic resin raw materials (threads) such as polypropylene, which are appropriately bundled and twisted, is placed.
When the cutting blade 3 is lowered, the rope 4 is cut. At this time, as shown in FIG. 5, the cuts 2a, 2b are formed obliquely by the tapered surfaces 3a, 3b of the cutting blade 3, and the shape of the cuts 2a, 2b is an ellipse having an area larger than the thickness of the rope 4, and The cuts 2a and 2b are welded together by cutting with the heat of the heater.

In this way, as shown in FIG. 6, the rope 4 cut into the length of the handle string is cut into the cut end 2a (2b) at the end of the rope through hole 6 formed in the upper part of the handbag 5 as in the conventional case. ), Both ends of the rope 4 are projected into the inside of the paper bag 5, and the projecting portions are tied together (stop knots) to form a knotted cob 7, and both ends of the rope 4 are stringed through the knotted cobs 7. The handle string 1 is made so that it does not get out of the position 6.

When the rope 4 is inserted into the string passing hole 6, the cuts 2a and 2b at the ends of the rope 4 are obliquely cut to have an elliptical shape, and the tips of the cuts 2a and 2b have a tapered shape. Therefore, the tapered cut ends 2a and 2b are first inserted into the string passage hole 6 for easy insertion.

Although the cutting blade 3 has the tapered surfaces 3a and 3b on both sides of the tip portion in the above embodiment, the shape is not limited to such a shape, and any other tip may be used as long as the tip has an acute angle. For example, as shown in FIG. 7, only one side of the tip portion may be the tapered surface 3a or 3b.

In this case, the end face of one of the cuts is formed obliquely, but the end face of the other cut is at a right angle.

However, if the rope is inserted into the string hole 6 in order using only the diagonally formed cut side, the rope can be smoothly inserted as in the case of the first embodiment.

[Effect of device]

As described above, the handle string for the handbag of the present invention has the cut surface formed to be elliptical by forming the cut surface obliquely, so that the cut surface having a large area can be secured as compared with the case of cutting at a right angle. As a result, the area is enlarged due to welding and the rope is less likely to come apart, which is convenient.

Further, since the tip of the cut end is formed in a tapered shape, it can be easily inserted into the string passing hole for the handbag and the workability can be improved.
