[Industrial applications]

 This invention relates to improvements in disposable chopsticks.

[0002]

[Prior art]

 Generally, a pair of chopsticks is used by separating a pair of chopsticks by pulling the pair of chopsticks apart from each other when the pair of chopsticks is joined at their base ends. And such split chopsticks usually have only the function as chopsticks. Furthermore, with conventional disposable chopsticks, the chopsticks that did not break well at the center were sometimes connected by a burr.

[0003]

[Problems to be solved by the device]

 By the way, chopstick rests used for meals are conventionally made of crockery and the like, and after use, they are washed and used many times like other tableware. This chopstick rest is not always necessary for meals, and since cleaning is complicated, it is often not available at ordinary restaurants or restaurants. For this reason, chopsticks should be hung on a plate such as a plate when resting food in such a place. Therefore, it would be very convenient if there were disposable chopsticks that could be used as a chopstick rest, and there was a strong demand for such disposable chopsticks.

The present invention has been made in view of the above circumstances, and of course, a part of it can be used as a chopstick rest, as well as a split chopstick that can cleanly shape the chopsticks after separation. The purpose is to do.

[0005]

[Means for Solving the Problems]

 The disposable chopsticks according to the present invention is a disposable chopstick which has a disposable chopstick body in which a pair of chopsticks are connected to each other at their base end portions. At least one surface of the chopsticks is provided with a notch that extends in a direction substantially orthogonal to the direction in which the chopsticks extend, and the chopsticks are joined together near this notch, and the chopsticks are cut from their tips to the notch. It is characterized by being separated from each other.

Here, when the cut portion is provided on the front and back surfaces of the disposable chopstick body, the thickness of the cut portion is preferably in the range of 0.4 to 2.0 mm, but the thickness is 0.8 to 1. If it is within the range of 2 mm, it is possible to reduce the occurrence of burrs after breaking the head from the disposable chopstick body, and the strength is sufficient.

[0007]

[Action]

 In the disposable chopsticks having the above-mentioned structure, the head is bent from the split chopstick body by bending the head along the notch, and the disposable chopstick can be used as a chopstick rest. Before breaking the head, the chopsticks are firmly connected via the head, so they will not be easily separated. On the other hand, since the chopsticks are separated up to the notch, the area of the joints between the chopsticks becomes small or zero after the heads are broken, so the chopsticks are separated from each other at the same time when the heads are broken, Alternatively, it can be easily separated with a little force. Therefore, in the disposable chopsticks having the above structure, a part of the disposable chopsticks can be used as a chopstick rest, and it is very easy to use and the shape of the chopsticks after splitting can be beautifully arranged.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 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 split chopstick body 1 is a plate-shaped body made of wood and having a rectangular cross section, and is formed so that its width gradually narrows from the base end portion toward the tip end portion. 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 (cutting portion) 4 substantially orthogonal to the chopsticks 2, 2 is formed at the base end portion of the disposable chopstick body 1 over the entire circumference of the disposable chopstick body 1, and a head portion 5 is located closer to the base end portion than the groove 4. Has been formed. The groove 4 has a V-shaped cross section, and the depth thereof 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. As a result, the thickness of the deepest valley line portion 4b of the groove 4 is 0.4 to 2.0 mm, and preferably 0.8 to 2.0 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 sides than on the side surface, or may be the same as the side. However, the present invention is configured as described above. It goes without saying that it is not limited to.

Next, the head 5 is for use as a chopstick rest after being cut off from the disposable chopstick body 1, and has a concave surface on its surface, the thickness of which gradually decreases from both ends toward the center. A curved surface 5a is formed. The concave curved surface 5a is provided to stabilize the chopsticks when the chopsticks are hung and placed.

When manufacturing the above-mentioned disposable chopsticks, a cutting member 3 is formed by making a vertical cut in a plate material having the external shape of the disposable chopsticks, for example, by a blade attached to the upper mold of a press. 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 made to coincide with the end edge of the cutting portion 3.

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 thereof. Then, the head portion 5 is separated from the chopstick body 1 at the valley 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 portion 4b, and due to the impact force transmitted when the head 5 is folded, The parts 5 are bent and separated from each other at the same time. 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, the head 5 can be used as a chopstick rest, which is very convenient. Further, since the cutting portion 3 of the chopsticks 2, 2 extends 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 conventional disposable chopsticks, there was a case where the chopsticks did not break well at the center or the chopsticks were connected by a burr after breaking, but with the above disposable chopsticks there was no such problem at all, and the form after separation was It can be beautifully arranged. Therefore, the usability during meals is also very good.

Even if the chopsticks 2, 2 are not separated well when the head 5 is bent, the chopsticks 2, 2 can be easily separated with a very small force. In addition, the head can be formed into a shape such as a flora and fauna or a character such as an animation, and such a pattern can be printed. It is also possible to form the head 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 house name can be printed or branded.

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. 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 edge of the cutting portion 12, and the base end side of the groove 13 is closer to the head. It is defined as part 14. The depth of the groove 13 is 1 to 4 mm. As a result, the distance between the valley line portions 13a and 13a is set to 1.5 to 10 mm, but a range of 2.0 to 8.0 mm is desirable. If the gap between the valley line portions 13a, 13a exceeds 8.0 mm, the cross section tends to come out when the head 14 is broken from the split chopstick body 10, and if it is less than 2.0 mm, the strength is insufficient. Become. However, the present invention is not limited to such a range.

In the disposable chopsticks having the above structure, the head 14 can be broken by bending the disposable chopstick body 10 in the width direction thereof. At that time, a crack is generated from the valley line portion 13a of the one groove 13 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 structure, the head 14 can be used as a chopstick rest, and moreover, since the chopsticks 11 and 11 are separated at the same time when the head is broken, it is very easy to use. The effect of is obtained. Further, since the groove 13 is formed on the side portion of the disposable chopstick body 10, the groove 13 can be processed simultaneously with the processing of the cutting portion 12 by mounting a cutter on the upper die of the press, for example. It can be manufactured with the same man-hours as the disposable chopsticks.

Although the groove is formed in a V-shaped cross section in the above embodiment, the shape is not limited to such a shape, and various changes can be made. It is also possible to form the grooves only on the front and back surfaces or on either of them. Further, the groove can be provided only on one side surface of the split chopstick body. FIGS. 4A to 4J are views showing an example of changing the groove, and are side views of the disposable chopstick body.

FIG. 4A is an example in which a groove having a V-shaped cross section is formed on the front and back surfaces of the split chopstick body, and FIGS. 4B and 4D show one surface of the groove 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 an example where the cross-sectional shape of the groove is rectangular or square, and (e) is an example where it is semi-circular or U-shaped. (F) is an example in which the cross-sectional shape of the groove is trapezoidal. (G) is an example in which the surfaces on both sides of the groove are convex curved surfaces and the bottom surface of the groove is a flat surface, and (h) is one in which the bottom surface is not provided and only the convex curved surface constitutes the groove.

(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. It is also possible to form a notch on the front and back surfaces of the disposable chopstick body or on only one surface. When making a notch, it is only necessary to push the cutting edge of the cutter mounted above the press into the body of the split chopsticks, which makes it possible to reduce manufacturing costs. 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.

The shape of the groove described above is merely an example, and the shape of the groove is arbitrary in the present invention. Further, the material is not limited to wood, and various modifications can be made such as plastic, or only the head is made of plastic and the other parts are made of wood.

By the way, in each of the above-mentioned embodiments, the head that is cut off from the disposable chopstick body is used as a chopstick rest, but the present invention is not limited to such a usage mode. For example, the disposable chopsticks of the present invention are constructed simply for the purpose of separating the chopsticks by utilizing the configuration that the heads are separated from the main body of the disposable chopsticks and at the same time the chopsticks are separated from each other. May be. In such disposable chopsticks, the disposable chopsticks can be broken with one hand by pressing the head with the thumb. In addition, when the head is broken off, burr can appear on the fracture surface of the head and the chopsticks, and the burr can be used as a toothpick. As described above, in the present invention, the broken head and the separated chopsticks can be used in any manner, and the usage mode is arbitrary.
