Abstract

PURPOSE:To manufacture metallic tableware which is light in weight and full of variety, by forming a neck section by pressing a base material from sides after a through hole extended in the longitudinal direction is formed in the base material, on the sides of which circular arcuate hollow grooves are formed, and press-forming a working section. CONSTITUTION:A hollow groove 5 is formed in the upper surface of a metallic base material 11 and circular arcuate surfaces 7 are formed on both sides. Then a through hole 6 is formed along the hollow groove 5 by punching. Thereafter, both sides of the base material 11 are pressed bu using a pair of dies 14, each of which is provided with an inclined pressing surface 13. As a result, widths of the groove 5 and through hole 6 are gradually narrowed as going toward the front end of the base material 11 and the front end of the hole 6 is closed by a joining line 9, and thus, a neck section 3 is formed. Then the part from the neck section 3 to the front end of the base material 11 is pressed and a spooning section 4, etc., is formed. This method can be applied to the manufacture of metallic tableware, such as fork, butter knife, etc., in addition to a spoon.

Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a method for manufacturing metal eating utensils such as spoons, forks, or butter knives.

(Prior Art) Conventionally, as this type of eating and drinking utensils, those having a concave or convex design extending over the entire length of the handle are known.

(Problem to be solved by the invention) However, in conventional eating and drinking utensils with this type of design, the width of the handle is almost constant over the entire length, so not only is there little variation, but also when the width is wide. The problem was that the thick shape of the neck made it look bad, and conversely, when the width was narrow, the entire handle became thin and difficult to handle.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, in this invention,
As shown in FIG. 1, a through hole 6 extends along the longitudinal direction of a metal base material 11 having an arcuate groove 5 on one side.
After forming the neck part 3, one end of the through hole 6 is closed by pressing the base material 11 corresponding to at least one end of the through hole 6 from the lateral direction, as shown in FIG. ,
A method is used in which a portion from the neck portion 3 to the tip of the plugging material 11 is pressed to form the working portion 4 according to the shape of the intended use.

(Function) Therefore, according to the above-described method of the present invention, weight reduction is achieved by forming the through holes 6 in the base material 11, and by closing one end of the through holes 6, the width is narrow and the appearance is good. It is possible to easily form a neck portion 3 with a good shape, and since the handle portion 2 of the eating utensil thus manufactured is provided with a concave groove 5 and a through hole 6, the design can be varied. Since the portion 2 has an arcuate groove 5, the eating utensils can be easily held by placing a finger there.

(Example) Hereinafter, an example in which the present invention is embodied in a spoon will be described based on the drawings.

First, the structure of the spoon manufactured by the method of the present invention according to FIGS. 2 to 9 will be described. The spoon 1 of this embodiment has a handle part 2, a neck part 3, and a scoop part 4 as an acting part.
It consists of. The handle part 2 is formed so that its width gradually becomes narrower toward the neck part 3, and an arcuate groove 5 is formed in the center part in the width direction so as to extend over almost the entire length. A through hole 6 is provided so as to extend along the groove 5, and the width gradually becomes narrower toward the neck portion 3. Arc surfaces 7 are formed on both sides of the handle 2, respectively. Furthermore, a finger hook 8 is formed at the base end of the handle 2 in a curved manner toward the back side.

Note that 9 shown in Fig. 3.4.6.9 is a joining line formed by closing one end of the through hole 6 during manufacturing.

Next, a method for manufacturing the spoon 1 having the above-described structure will be explained.

Now, FIG. 1 shows a metal base material 11 before processing, and the groove 5 is formed on the top surface of the base material 11, and the arcuate surfaces 7 are formed on both sides of the metal base material 11 by pultrusion or the like. has been done. First, the base material 11 is cut to a predetermined length at the position shown by the dashed line in the same figure, and then the through hole 6 is punched out along the groove 5, so that the base material 11 has the pattern described above. Section 2 is formed. When punching the through hole 6, a wide portion 12 is formed at one end of the through hole 6 on the side where the neck portion 3 is formed, the wide portion 12 gradually becoming wider than the pond portion toward the tip.

Next, the base material 11 is placed between a pair of pressing molds 14 having oblique pressing surfaces 13, and both pressing molds 14 are brought together to press both side surfaces of the base material 11 corresponding to the through holes 6, respectively. As a result, the widths of the groove 5 and the through hole 6 become gradually narrower toward the distal end, and the distal end of the through hole 6 is closed at the joining line 9 described above, resulting in the cross-sectional shape shown in FIG. A neck 3 is formed. In this case, since the wide portion 12 is provided in the through hole 6, the thick portions on both the left and right sides of the base material 11 are combined, and the neck portion 3 has a substantially circular cross section, providing sufficient strength and a clean design. be able to.

Subsequently, the tip portion of the base material 11 from the neck portion 3 to the tip is pressed by a well-known method using a press or the like to form the scoop portion 4. The bending process of the finger hook part 8 can be performed either before or after the scoop part 4 is molded.

After the spoon 1 having the shape shown in FIGS. 2 to 6 is formed in this way, the entire surface of the spoon 1 is polished, but the base material 11 is subjected to a drawing process or the like to form the grooves.
In addition, since the arcuate surfaces 7 are each formed smoothly in advance, polishing of the entire handle 2 including the neck 3 can be easily performed in a short time.

Therefore, according to the method for manufacturing the spoon 1 of this embodiment described above, the handle 2 is tapered, the neck 3 is approximately circular in cross section, the through hole 6 is gradually narrowed toward the neck 3, and the through hole is 6
Spoon 1 with a variety of designs including an arcuate groove 5 extending along the curve, an arcuate surface 7 on both sides of the handle 2, and a finger rest 8.
can be produced easily and in a short time. Moreover, since the spoon 1 manufactured by this method is provided with the through hole 6, it is light and durable, and it is easy to use by placing the fingers on the concave @5 and the finger rest 8 respectively.

It should be noted that the present invention is not limited to the production of the above-mentioned spoons, but can also be applied to the production of other metal eating utensils such as forks and butter knives.

Effects of the Invention As detailed above, according to the present invention, there is an excellent effect that metal eating and drinking utensils with Rm and a design with many variations can be easily produced.
