Description

[Detailed description of the invention] The spoon of this invention relates to a spoon used for stirring instant coffee or tea sold in paper cups, ice cream packed in highly viscous cups, jam, yogurt, pudding, etc., or used for eating and drinking. .

It is currently made of synthetic resin that is integrally molded for stirring and dissolving sugar and additives that are added before drinking drinks such as coffee and tea, or for drinking and drinking ice cream and pudding in cups. Spoons and wooden spoons are often sold attached to instant drinks and cupped foods.

If we look at the conventional manufacturing method of synthetic resin spoons,
Most of them are made by heating and melting Bosch Styrol resin and manufacturing them all at once using a large-scale spoon molding machine, and the equipment and costs are unavoidable.Unless mass production is done, the unit price is inevitably high. These prices are becoming more expensive, which is also having an impact on cup-based food and drink products.

Furthermore, when the synthetic resin spoons made of polystyrene resin are incinerated after use by the above-mentioned manufacturing method, they generate pollution such as toxic gas and black smoke, which is not sanitary.

On the other hand, the production cost of wooden spoons is becoming too much to ignore due to the soaring unit price of wood.

Furthermore, due to the wood grain, it is currently difficult to clearly print letters, pictures, etc. on the surface.

Furthermore, if we look at the conventional packaging formats for wooden spoons and synthetic resin spoons, the material is too rigid, making it difficult to automatically package them mechanically, so packaging must be done manually. This was undesirable because it led to high unit costs and there were many opportunities for bacteria to adhere to the spoon.

The present inventor has already proposed several types of paper spoons in response to the above-mentioned current situation, but the basic structure of these previously proposed paper spoons is that the gripping part is folded into a roughly V-shaped cross section. The container is further folded along the folding line to form a flat surface at the tip for use in stirring or scooping up beverages.

Even if they can be used by themselves, depending on the paper material, its thickness, or the way in which the continuous folding line is attached, the entire spoon may become soft or stiff due to seeping liquid. They have the disadvantage that they are not useful for scooping highly viscous foods and drinks, or that they are easily bent due to their lack of rigidity.

In addition, there are conventional spoons with two folded lines in the longitudinal direction of the handle, and spoons with split legs connected to the handle, but even spoons with this shape can be used with paper, etc. When the material was folded, there was a defect in which the strength of the folded line was reduced.

This invention is an attempt to improve paper spoons, which can be produced at low cost and which had defects in use.It is made of plate-shaped cardboard or a material of the same quality, and has an original shape of an elongated shape. A base piece is formed in the center in the longitudinal direction excluding the tip portions that are the outer edges on both sides, and two folded lines are formed through the base piece, and on the other hand, from the boundary between the tip portion and the elongated shape portion to the tip end of the tip portion. A V-shaped folded edge reaching the outer edge is provided, and both outer edges are formed at the tip portion and stand at an angle with the spoon receiving part, and a discontinuous part is formed between the folded line and the two folded lines. This is an idea about a spoon.

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a spoon 1 formed by punching a plate-shaped cardboard.

The material of the spoon 1 according to the present invention is preferably cardboard as shown in the embodiment, but it is not limited to cardboard, and can be made of a material with the same effectiveness as cardboard, i.e., synthetic paper made by bonding a polyolefin resin thin film to cardboard. Even if thin sheets of synthetic resin are used as a material, they can be expected to have the same effect as cardboard by organically bonding inorganic minerals (e.g. gypsum) to polyolefin resin and do not cause pollution such as toxic gas or black smoke. The purpose of the present invention can be achieved.

1 is a spoon according to the present invention, 2 is a tip portion that constitutes a flat receiving part 17 of the spoon 1 and outer edges 3 and 4 on both sides, and the outer edges 3 and 4 are connected to the receiving part 17 of the spoon 1. Stand up on an incline.

An elongated portion 5 is formed in a continuous manner with the tip portion 2, and the elongated portion 5 is also connected with both outer edges 3 and 4 which are erected at an angle.

Furthermore, a base piece 6 is formed in the longitudinal center of the elongated portion 5 excluding the tip portion 2.

7 and 8 are two folding lines provided through the base piece 6, and 9.10 is the inner end of the folding lines 7 and 8, and the terminal ends 9 and 10 are bent as shown in the second figure. They are crossed at a position close to the receiving part 17, so that the folding force for soil removal during the folding is crossed.

11.12 is a boundary between the tip portion 2 and the elongated portion 5 in order to form a holding portion to facilitate the folding of the spoon and to reliably scoop viscous foods such as ice cream and jam. It is a V-shaped fold line provided in the portion, and the tip thereof is located at the outermost edge 18 of the spoon receiving portion 17.
It has reached 19.

Furthermore, outer edges 3 and 4 on both sides are connected to the spoon receiving part 17 through a square folding line 11 and 12 at the tip end part 2, and a discontinuous part is formed continuously to the folding of the elongated part 5. 13
．． 14 is also folded in, and the outer edges 3 and 4 on both sides are erected obliquely, thereby preventing them from expanding to both sides.

The tip portion 2 is formed into an oval shape, and the receiving portion 17 of the spoon and the outer edges 3 and 4 on both sides work together to ensure that the viscous food or drink can be scooped out, so that the scooped food or drink does not reach the outer edge. This can prevent overflow.

The discontinuous portion 13.14 is provided between the two folding lines 7, 8 and the square folding line 11.12.

Continuing with the folding of the two folding lines 7 and 8 as described above, the discontinuous portions 13 and 14 are also folded in.

The paper that is used as the material for spoons and other similar materials have a defect in that when they are folded, especially when folded along the folding lines, fibers and compositions are folded in, reducing the strength of the folded parts. There are defects that reduce the strength in the direction.

The previous model had two folding lines in the longitudinal direction of the handle and one folding line on the holding part, but it was also possible to extend the appropriate number of auxiliary folding lines in the shape of branches beyond the folding line. It is known that spoons have two parallel folding lines at the clasp and two parallel folding lines at the clasp, but this type of spoon has a columnar folding line at the clasp. A defect occurred in which the strength of the part in the transverse direction was reduced, that is, a defect in which the strength of both end edges of the holding part was reduced.

Therefore, as in the present invention, the tip portion 2 is provided with a V-shaped folding line 11.
．． The spoon receiving part 17 is formed into a flat shape by 12,
In addition, when raising the outer edges 3 and 4 on both sides at an angle, the fold line 7
, 8, the discontinuous portions 13.14 are folded in, and the outer edges 3.4 on both sides are erected at an angle, and this connects with the receiving portion 17 of the spoon to form a spoon in which the tip portion 2 is shaped like an abbreviation. Even if the receiving part 17 of the spoon is flat, it maintains the strength in the transverse and longitudinal directions of the spoon receiving part 17, and prevents the outer edges 3.4 on both sides from expanding to both sides.
It has the effect of preventing a decrease in strength.

Furthermore, the strength of the spoon in the opposite direction to the scooping direction when using the spoon was reduced, which was a defect of the spoon in which the folding lines were connected to each other in the scooping part.
In the spoon according to the present invention, the possibility of formation of continuous folding lines, which causes a decrease in the strength of this type of spoon, is minimized, and the folding lines 7, 8 and the square folding line 11.
Discontinuous portions 13 and 14 are formed between the tip and the tip 12 to maintain strength in the scooping direction.

Reference numerals 15 and 16 are gripping portions formed by folding the elongated portion 5 inward from the two folding lines 7 and 8.

Although the present invention is constructed as described above, the folding lines 7 and 8 may be folding lines or perforated cut lines, or both may be used in combination as shown in FIG.

Further, the V-shaped folding lines 11 and 12 may be continuous folding lines or perforated cutting lines as shown in the second figure, or a combination of both may be used.

These folding lines 7, 8, 11.12 are formed by punching cardboard or the like.

When the spoon of the present invention configured as described above is used for stirring or eating and drinking, the folding line 7,
8 and the folding lines 11 and 12 from the original shape of the spoon to form a spoon.

In this way, the work of forming the spoon is facilitated and the shape of the spoon can be formed reliably, and the strength of the spoon can be maintained.

Since the spoon of the present invention is constructed as described above, the base piece formed in the elongated portion and the gripping portion can prevent the spoon from bending in the longitudinal direction during use, and the tip portion is provided with a V-shaped folding line. Therefore, the spoon receiving part and the outer edges on both sides work together to maintain a constant shape with the tip part omitted, and a discontinuous part is formed at the tip part, the elongated shape part, and the boundary part, and the folding is continuous. , it has strong resistance to bending of the spoon holder in the scooping direction and the backward direction, and as a result, it is possible to reliably scoop foods such as ice cream with high viscosity, and the scooped food and drinks can be easily bent in the scooping direction and in the backward direction. It is possible to provide a whole spoon or a spoon that does not bend without overflowing.

Furthermore, the spoon of the present invention has a simple structure and is extremely easy to manufacture and use in a length that allows processing of cardboard or other materials of the same quality. In addition, the material maintains some flexibility and is suitable for mechanical processing, can be easily packaged automatically, can be stored and transported in a flat state, and has a good printing effect and incineration process with no pollution. Can provide spoons without cause.
