DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described with reference to. FIG. 1 is a perspective view showing the disposable chopsticks of the embodiment. In the figure, reference numeral 1 is a main body of disposable chopsticks.
The disposable chopstick body 1 is a plate-shaped body made of wood and having a rectangular cross section.
The width is gradually reduced from the base end toward the tip. Chopsticks 2, 2 are formed on the disposable chopstick body 1, and these chopsticks 2, 2 are separated from each other by a cutting portion 3.

A groove 4 which is substantially orthogonal to the chopsticks 2, 2 is formed at the base end of the disposable chopstick body 1 over the entire circumference of the disposable chopstick body 1, and a head 5 is formed closer to the base end than the groove 4. There is. The groove 4 has a V-shaped cross section, and its depth is 1 to 2 mm on the front and back surfaces of the disposable chopstick body 1 and 2.5 to 4 mm on the side surface.
Thereby, the thickness of the deepest valley line portion 4b of the groove 4 is set to 0.4 to 2.0 mm, and preferably 0.8 to 2.
It is set to 0 mm. If the thickness exceeds 2.0 mm, burrs are likely to appear on the cross section when the head 5 is broken off from the split chopstick body 1, and if less than 0.8 mm, the strength becomes insufficient. A more desirable range is 0.8 to 1.2 mm, and about 1 mm is most suitable. The depth of the groove 4 may be deeper or shallower on the front and back surfaces than on the side surface, or may be the same depth. However, the present invention is configured as described above. It goes without saying that it is not limited to.

Next, the head portion 5 is for use as a chopstick rest after being broken from the disposable chopstick body 1, and the surface thereof has a concave portion whose thickness gradually decreases from both end portions toward the central portion. A curved surface 5a is formed. This concave curved surface 5
“A” is provided to stabilize the chopsticks when the chopsticks are hung and placed.

When manufacturing the above-mentioned disposable chopsticks, a plate having the outer shape of the disposable chopsticks is cut vertically by a blade attached to the upper die of the press to form the cutting portion 3. Next, the groove 4 and the concave curved surface 5a are formed by an electric plane or the like. At that time, the edge portion 4a of the groove 4 is cut into the cutting portion 3
Match the edge of.

When using the disposable chopsticks having the above structure,
First, the disposable chopstick body 1 is gripped and the head 5 is bent in the thickness direction. Then, the head 5 is separated from the split chopstick body 1 at the valley line portion 4b. As a result, the chopsticks 2, 2 are connected to each other only at a small portion from the edge 4a of the groove 4 to the valley line portion 4b, and due to the impact force transmitted when the head 5 is bent, At the same time the 5 are bent, they are separated from each other. Then, the head 5 is placed on a table or the like with its concave curved surface 5a facing upward, and this is used as a chopstick rest.

In the disposable chopsticks having the above structure, its head 5
It is very convenient because you can use it as a chopstick rest. Particularly, in the above-mentioned embodiment, since the cutting portion 3 of the chopsticks 2, 2 is extended to the groove 4, the chopsticks 2, 2 can be separated at the same time when the head 5 is broken, which is very easy to use. . Also, with the conventional disposable chopsticks, there was a case where the chopsticks did not break well at the center or the chopsticks were connected with a burr after breaking, but with the above disposable chopsticks, such a problem did not occur at all, so after separating, The shape of the chopsticks 2 can be beautifully arranged, and the feeling of use during meals is also excellent.

If the chopsticks 2, 2 are not separated well when the head 5 is bent in the above embodiment, the cutting portion 3 may be extended to the valley line portion 4b side of the groove 4. Further, the head can be formed into a shape such as a flora and fauna or a character such as an animation, or such a pattern can be printed. Also, the head can be formed in the shape of characters such as hiragana, katakana, kanji, romaji, and other foreign languages. Further, the head can be formed in the shape of a restaurant mark or a family crest, such a pattern can be printed, or a store name can be printed or branded.

By the way, in the above-mentioned embodiment, the head 5 is cut off from the split chopstick body 1, and at the same time, the chopsticks 2 and 2 are separated from each other, but the present invention is not limited to such a construction. Alternatively, the cutting portion 3 and the groove 4 may be separated from each other. As a result, after the head 5 is cut off,
Like the conventional disposable chopsticks, it is necessary to pull and break the chopsticks 2 and 2, but if the cutting part 3 is brought close enough to the groove 4, the chopsticks 2 and 2 can be broken with a small force, and The shape of the chopsticks 2 after the opening can be beautifully arranged.

Next, FIG. 3 is a plan view showing another embodiment of the present invention. Reference numeral 10 in the figure is a disposable chopstick body. Also,
Reference numeral 11 is a chopstick, and the chopsticks 11 and 11 are separated from each other by a cutting unit 12. A groove 13 having a V-shaped cross section is formed on the side surface of the disposable chopstick body 10 on the base end side, with its valley line portion 13a located at the end edge of the cutting portion 12, and the base end side of the groove 13 is the head. It is defined as part 14. The depth of the groove 13 is 1 to
It is set to 4 mm. As a result, the valley line portions 13a, 13
The distance between a is 1.5 to 10 mm,
A leaf of 2.0 to 8.0 mm is preferable. Valley line portion 13a,
If the distance between the 13a exceeds 8.0 mm, burrs are likely to appear on the cross section when the head 14 is broken off from the split chopstick body 10, and if less than 2.0 mm, the strength becomes insufficient. However, the present invention is not limited to such a range.

In the disposable chopsticks having the above construction, the head 14 can be broken by bending the head 14 in the width direction of the disposable chopstick body 10. At that time, one groove 1
A crack is generated from the valley line portion 13a of No. 3 and reaches the valley line portion 13a of the other groove 13, and at the same time, the chopsticks 11 and 11 are separated from each other.

In the disposable chopsticks having the above-mentioned structure, the head 14 can be used as a chopstick rest, and the chopsticks 11 and 11 are separated at the same time when the head is broken, so that it is very easy to use. The effect of is obtained. Further, since the groove 13 is formed on the side of the disposable chopstick body 10, for example, by mounting a cutter on the upper die of the press, the groove 13 can be processed at the same time as the processing of the cutting portion 12,
It can be manufactured with the same man-hours as conventional disposable chopsticks.

In the above embodiment, the cutting portion 12 is formed into the groove 13.
Although it is aligned with the valley line portion 13a, it does not necessarily have to be aligned. Further, although the groove is formed to have a V-shaped cross section, it is not limited to such a shape and various modifications can be made. Further, the grooves can be provided only on the front and back surfaces or on only one of them. further,
The groove can be provided only on one side of the split chopstick body. 4A to 4J are views showing an example of changing the groove, and are side views of the disposable chopstick body.

FIG. 4 (a) shows an example in which grooves having a V-shaped cross section are formed on the front and back surfaces of the split chopstick body, and in FIGS. 4 (b) and 4 (d), one surface of the grooves is made substantially orthogonal to the front and back surfaces. , The other surface of the groove is inclined with respect to the front and back surfaces. (C) is
It is an example where the cross-sectional shape of the groove is rectangular or square,
(E) is an example of a semicircular shape or a U shape. (F) is an example in which the cross-sectional shape of the groove is trapezoidal. (G) is an example in which both sides of the groove are convex curved surfaces and the bottom surface of the groove is a flat surface.
In (h), the groove is formed only by the convex curved surface without providing the bottom surface.

(I) is an example in which a groove having a V-shaped cross section is formed on the front surface of the disposable chopstick body, and a notch is formed on the back surface. In addition,
It is also possible to form notches on the front and back surfaces of the disposable chopstick body or on only one surface. When forming a notch, it is sufficient to push the cutting edge of the cutter attached above the press into the main body of the chopstick, so that the manufacturing cost can be reduced. Further, the notch may be provided around the entire circumference or only the side surface of the split chopstick body. Next, (j) is an example in which a groove having a rectangular cross section is formed on the entire circumference of the disposable chopstick body. In this example, the depth of the groove may be uniform, or the depths of the front and back surfaces and the side surface may be different from each other.
