Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to plastic disposable chopsticks.

[0002]

[Prior art]

 As is well known, disposable chopsticks are generally made of wood.In recent years, however, wooden disposable chopsticks, which are made of disposable wood, are unfavorable from the viewpoint of resource conservation.On the other hand, there is a great demand for disposable chopsticks with a sense of cleanliness. Plastic disposable chopsticks have been proposed. The conventional plastic disposable chopsticks are composed of a pair of plastic chopsticks connected at their base ends with connecting pieces as described in Japanese Utility Model Publication No. Sho 63-19620 and Japanese Utility Model Publication No. 2-143073. Is.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional plastic disposable chopsticks merely replace the material of the wooden disposable chopsticks with plastic, and do not take advantage of the advantage of adopting plastic chopsticks.

Injection molding processing is adopted in the production of ordinary plastic chopsticks. In the injection molding processing, a spool is used to fill a cavity (mold of the chopstick body) with a molding material. It is equipped with a runner part that guides the molding material from the part that joins the nozzle of the injection molding machine to the molding die, and a gate part that guides the molding material from the runner part to the molding die. It is provided at the base end of the chopstick body, and when the molding material solidifies, it is cut off at the gate to make a product.

That is, the plastic chopsticks are like disposable chopsticks in the manufacturing process, and the solidified resin in the runner portion and the gate portion is discarded. Therefore, the present invention proposes a novel plastic disposable chopsticks that effectively uses the discarded portion in the manufacturing process of the plastic chopsticks described above and further adds value.

[0006]

[Means for Solving the Problems]

 The plastic disposable chopsticks according to the present invention comprises a pair of chopstick bodies arranged side by side, an injection molding gate portion and a runner portion continuous with the base portion of the chopstick body portion, and a flat plate portion continuous with the runner portion. It is a feature.

Further, in the above-mentioned plastic disposable chopsticks, in particular, the flat plate portion is provided with a desired name, or the flat plate portion is placed at a position opposite to the chopstick body portion in parallel with the arrangement of the chopstick body portions. It is characterized in that it is formed on orthogonal planes.

[0008]

[Action]

 If the gate part and runner part that are cut in the normal plastic chopstick manufacturing process are left, the user can fold and separate the gate part to use it as disposable chopsticks.

In addition, since the flat plate part is continuously provided in the separated runner part, the runner part can be stably placed on a table and used as a chopstick rest, and by putting a desired name on the flat plate part, It can also be used to advertise the store.

【Example】

 Next, an embodiment of the present invention will be described. First Embodiment FIGS. 1 to 3 show a first embodiment of the present invention. The plastic disposable chopsticks shown in the embodiment are molded and formed of plastic suitable for food hygiene, and are composed of chopstick bodies 1a and 1b, a gate portion 2, a runner portion 3, and a flat plate portion 4. The chopstick body portions 1a and 1b are a pair of chopstick body portions arranged side by side so that they can be easily used as chopsticks by making the tip end part of the chopstick like a normal plastic chopstick.

The gate portion 2 and the runner portion 3 have a shape corresponding to the injection molding of the chopstick body portions 1a and 1b, and the runner portion 3 is an appropriate one in consideration of the fluidity of the resin of the molding material and the cooling time. It is formed to have a large thickness, and is connected to the sprue to form a flow path for the molding material during manufacturing. The gate portion 2 connects the base end portions of the chopstick body portions 1a and 1b to the runner portion 3 as in the conventional manufacturing of plastic chopsticks.

The flat plate part 4 is continuous with the runner part 3 and is opposite to the entrance part of the gate part 2 so as not to obstruct the filling of the molding material from the gate part 2 into the chopstick parts 1a, 1b. It is formed on the side, and in particular, it is formed in parallel with the arrangement of the chopstick bodies 1a and 1b, and an appropriate display 41 by printing or sticking a sticker or an uneven shape is provided on the surface thereof.

Since the gate part 2 of the above chopsticks is sufficiently thin as compared with the chopstick bodies 1a and 1b and the runner part 3, the chopsticks can be cut by easily bending them and can be used as disposable chopsticks. Especially, the cut runner part 3 etc. can be stably placed on the table due to the existence of the flat plate part 4 and can be used as a chopstick rest. Can also be used.

<Second Embodiment> FIGS. 4 to 6 show a second embodiment. In this second embodiment, chopstick bodies 1a and 1b and a gate portion 2 are also provided as in the first embodiment. Although the runner part 3A has a shape in which both sides are bent toward the chopstick body side, the flat plate part 4A has an inverted T-shaped end face opposite to the chopstick body parts 1a and 1b. It is formed on a plane orthogonal to the arrangement of body parts.

Therefore, in use, when the flat plate portion 4A is placed on the table as shown in FIG. 6 with the rest of the chopstick bodies 1a and 1b separated by the gate portion, the runner portion 3 serves as a chopstick receiver. It can be used as a chopstick rest.

The present invention is not limited to the above-mentioned embodiment, and if the flat plate portion is connected to the runner portion so that the entire runner portion and the flat portion can be stably placed on the table. The position and size of the flat portion can be arbitrarily determined.

[0017]

[Effect of device]

 As described above, according to the present invention, the gate portion and the runner portion, which are necessary in the injection molding process of plastic products, are used as they are as the connecting portion of the disposable chopsticks, and the flat plate portion is connected to the runner portion to connect the chopsticks. Since the part other than the body can be used as a chopstick rest, it is not necessary to form the connection part of the disposable chopsticks, it can be formed by ordinary plastic injection molding, and the runner part that was previously discarded can be effectively used. Is.
