Japanese Utility Model Laid-Open No. 60-029563

In food stores, tableware such as spoons and forks that are attached to purchased food and provided to purchasers are generally made of plastic. In addition, it is customary to throw away once used, but in recent years, there is a demand for reduction of plastic waste. In addition, there is a need to reduce the cost of this type of tableware, regardless of whether it is provided to the purchaser for free or for a fee.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a tableware such as a spoon that contributes to reduction of plastic waste and cost reduction.

In order to solve the above problems, the tableware according to the present invention is a tableware member made of paper that integrally includes a tableware body that comes into contact with food and a short handle that protrudes from the tableware body,
a long handle longer than the short handle and detachably joined to the short handle;
characterized by comprising

According to the tableware, the use of paper as the tableware member contributes to the reduction of plastic waste. By reusing the long handle while the tableware member is disposable, even if the long handle is made of plastic, it further contributes to the reduction of plastic waste. In addition, the tableware member is made of paper, and the long handle can be reused, thereby contributing to cost reduction.

It is preferable that the short stem portion includes at least a cross-sectional portion that is curved or bent while being joined to the long stem portion.
By this, the bending strength (difficulty in bending) of a tableware member can be improved.

It is preferable that the cross-sectional portion, before being joined to the elongated stem, is more gently curved or bent than in a state where it is joined to the elongated stem, or is flat.
In other words, it is preferable that the long handle is joined to the tableware member while curving or bending the short handle. As a result, the bending strength (difficulty in bending) of the tableware member can be improved, and the bonding strength (difficulty in coming off) between the tableware member and the long handle can be ensured.

It is preferable that the length of the short handle portion is shorter than the length of the tableware main body.
As a result, the size of the tableware member can be reliably reduced, and the material cost can be further reduced.

It is preferable that the short stem portion has a length of 10 mm to 25 mm.
As a result, a sufficient joining length between the short handle and the long handle can be ensured. Moreover, the size of the tableware member can be reliably reduced, and the cost can be surely reduced.

It is preferable that an insertion hole into which the short handle is inserted is formed in an end face of the long handle facing the tableware main body.
The tableware member and the long handle can be joined by inserting the short handle into the insertion hole.

It is preferable that the long handle portion has a pair of clamping portions that sandwich the short handle portion.
By sandwiching the short handle between the pair of holding parts, the tableware member and the long handle can be joined. The pair of holding parts may be connected via a hinge so as to be relatively rotatable, or may be separable and fittable without such a connecting part.

It is preferable that the long handle is provided with a retaining mechanism for the short handle.
For example, it is preferable that, as the retaining mechanism, a pressing convex portion for pressing the short handle is formed on at least one facing surface of the pair of holding portions.
As a result, when the pair of clamping parts are closed and the short handle is sandwiched between them, the pressing protrusion presses the short handle, thereby preventing the short handle from coming off, and joining the tableware member and the long handle. The strength (hardness to come off) can be increased.

It is preferable that the pressing projections are arranged at mutually displaced positions on the opposing surfaces of both holding portions.
As a result, the short handle can be more reliably retained, and the joint strength between the tableware member and the long handle can be further increased.

It is preferable that the long handle is made of a harder material than the short handle.
Examples of materials for the long handle include plastics and metals. As a result, the long handle can be reused many times over a long period of time.

It is preferable that the tableware main body is a spoon portion, a fork portion, or a knife portion.
It is preferable that the tableware member made of paper is provided with an indication such as a stamp indicating that it is made of paper.
Paper includes cellulose and pulp.

The tableware and tableware member according to the present invention can contribute to reduction of plastic waste and cost reduction.

The tableware member 10 is made of paper. Paper includes cellulose and pulp. Preferably, the tableware member 10 is made by pressing and compressing the material paper and hardening it.
Although detailed illustration is omitted, the tableware member 10 made of paper is provided with an indication such as a stamp indicating that it is made of paper.

As shown in FIGS. 1 and 2, the tableware member 10 integrally includes a spoon portion 11 (a tableware main body in contact with food and drink) for scooping and mixing food and drink, and a short handle portion 12 . A short handle portion 12 protrudes from the root portion of the spoon portion 11 (tableware main body).

The short stem 12 includes a curved or bent cross-sectional portion. Specifically, the short handle portion 12 is curved downward in a U-shaped recess.
The length of the short handle 12 is preferably shorter than the length of the spoon 11 . For example, the length of the short handle portion 12 is about 10 mm to 25 mm.

The long handle 20 is longer than the short handle 12 . The length of the long handle 20 is, for example, about 50 mm to 120 mm.
The long handle 20 is made of a harder material than the short handle 12 . Examples of materials for the long handle 20 include plastics and metals.

An insertion hole 22 is formed in an end surface 21 of the long handle 20 facing the tableware member 10 . The insertion hole 22 is formed to have the same cross section as the U-shaped curved cross section of the short handle 12 .
By inserting the short handle portion 12 into the insertion hole 22, the long handle portion 20 is detachably joined to the short handle portion 12 and thus the tableware member 10.例文帳に追加

The spoon 1 (tableware) is used, for example, as follows.
The tableware member 10 is attached to the food and provided to the user each time the user purchases a predetermined food at a food store.
On the other hand, the long handle 20 is possessed or carried by the user in advance. Of course, you may provide a user from a food store.
A user inserts the short handle portion 12 of the tableware member 10 into the insertion hole 22 of the long handle portion 20 when eating and drinking the purchased food. Thereby, the tableware member 10 and the long handle 20 are joined. This allows the handle 2 of the spoon 1 to be of a suitable length for holding by hand. Therefore, the spoon 1 can be used to comfortably eat and drink, and the convenience of the spoon 1 can be ensured.
By forming the short handle portion 12 into a curved cross-sectional shape, the strength of the short handle portion 12 can be ensured, and the stress acting on the short handle portion 12 during eating and drinking can be sufficiently withstood.
By setting the length of the short handle portion 12 to 10 mm to 25 mm, a sufficient joint length between the short handle portion 12 and the long handle portion 20 can be ensured.

After eating and drinking, the short handle 12 is pulled out from the insertion 22 to separate the tableware member 10 from the long handle 20.例文帳に追加
Then, the paper tableware member 10 is discarded.
On the other hand, the long handle 20 is washed and stored. This allows the long handle 20 to be reused.

According to the spoon 1, by making the tableware member 10 made of paper, it is possible to contribute to the reduction of plastic waste.
By reusing the long handle 20 while the tableware member 10 is disposable, even if the long handle 20 is made of plastic, it is possible to further contribute to the reduction of plastic waste.
Furthermore, the cost can be reduced by making the tableware member 10 made of paper and by enabling the long handle 20 to be reused. By making the length of the short handle portion 12 of the tableware member 10 shorter than the length of the spoon portion 11, the overall size of the tableware member 10 can be reduced, and the material cost can be further reduced.
