Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a titanium rice scoop, and more particularly, to a titanium rice scoop having a low thermal conductivity and a colorful color even though it is a metal rice scoop. .

[0002]

2. Description of the Related Art Traditionally, rice scoops of this type are made of wood, bamboo,
It was made of plastic and partly made of stainless steel.

[Problems to be Solved] Conventional wooden and bamboo products have poor cleaning properties, and there is a problem that debris is mixed. In addition, there is concern about the effects of environmental hormones on plastic products. HACC, which is a method of making safe food at the cooking stage, in terms of hygiene, as seen in O-157 etc.
The problem of introducing P is being highlighted. Especially in nurseries, kindergartens, and elementary schools that handle children who are in the process of growing, we must use our nerves.
There are some rice scoops of stainless steel products, but there is a problem that the temperature of rice is transmitted and it becomes hot because stainless steel has a high specific heat. In addition, stainless steel had a unique taste of metal, and the luster of stainless steel was dry and tasteless.

DISCLOSURE OF THE INVENTION As a result of studying in view of the above problems, the present invention has revealed that in a scooping machine having a scooping plate part and a handle part, the scooping plate part and the handle part are made of titanium or titanium alloy as the material of the scooping machine. Is an integrally molded or hollow integrated type, and the surface of the scooping plate is embossed to prevent rice from sticking, and the surface of the rice scoop is subjected to oxidation coloring to form an oxidation coloring film. It was formed.

[0004]

EFFECTS OF THE INVENTION The scoop of the present invention is made of titanium or titanium alloy and is light in weight and has low thermal conductivity, so it is easy to handle even for elementary school children, and the scooping plate and the handle are integrally formed, or the handle is Since the parts are integrally molded, there are no seams and the like, so it is easy to wash and becomes a sanitary rice scoop. Also, by embossing, corroding, or embossing by sandblasting, etc., it becomes difficult for rice to stick and it becomes easy to handle. In addition, it is possible to achieve a variety of expressions by coloring the oxidative coloring film by the oxidative coloring process, or by patterns.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The scooping of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of an embodiment of the present invention.
FIG. 2 is a perspective view of another embodiment of the present invention. Figure 3
It is a perspective view which provided the embossing on the scooping board part of this invention. FIG. 4 is a partial cross section of an emboss provided on the scooping plate portion of the present invention,
It is a perspective view. FIG. 5 is a sectional view of the oxidative coloring surface of the present invention.

FIGS. 1, 2, and 3 relate to a titanium rice scoop of the present invention. More specifically, the metal rice scoop has a low thermal conductivity and the scooping plate portion is rice. The present invention relates to a titanium scoop that has less color and has a colorful color.

The outline of the manufacturing process of the present invention is as follows. A titanium material is punched out, the part to be the scooping plate part 9 is rolled, the plate thickness is set to about 1 to 3 mm, and the scooping plate part 9 after punching is punched out. After half-cutting is performed, the whole shape is adjusted by molding die pressing or edging processing for forming the edge of the whole scoop, and then the whole is polished to obtain the integrated scoop 1. Examples of the polishing method include chemical polishing and mechanical polishing.

In order to make it hollow, as shown in FIG. 2 (a), the scooping plate portion 9 and the grip portion 10 are integrally molded and stamped, and the scooping plate handle main body portion 2 and the mold stamping grip portion piece 3 are molded. 2B, which is an integral hollow scissor 4 having a hollow portion 8 by welding or brazing with a silver braze in nitrogen gas or the like. Figure 2
In (b), only the handle portion 10 is hollow, but the whole may be the middle type. When embossing is further performed, there are a method of knurling the scooping plate portion 9 and a method of molding the embossed surface 5 and FIG. 3 by pressing with a die having an embossing pattern, corrosion, or sandblasting (by masking). . As shown in FIG. 4, the embossed surface 5 has a substantially semicircular convex protruding portion 5a having a diameter of about 0.5 mm to 2 mm and a concave concave portion 5b arranged continuously or irregularly. They may be arranged in a pattern, arranged in a pattern, or a combination thereof. When sandblasting directly, it will form the original surface. Alternatively, the embossed surface may be wrinkled. Regarding the relationship between embossing and polishing, there is a method of performing embossing after polishing and then polishing again, but there is also a method of polishing the whole after embossing. The embossing may be performed at the same time as the embossing. When the forming die pressing or embossing is performed after rolling, the forming die pressing or embossing is easier by tempering the member, but the scale removing step for the scale adhesion due to the tempering is increased. Further, by forming a coating film surface 6 of fluorine resin, silicon resin or the like on the surface, it is possible to further reduce the sticking of rice or the like.

Further, a method of forming an oxidative coloring film on the surface by oxidative coloring is to form a transparent oxidative coloring film surface 9 on the surface of the rice scoop by means of, for example, a method called anodic oxidation. The coloring film causes light interference due to the phase difference between the light reflected on the surface and the surface of the scoop.
Depending on the thickness of the oxidative coloring film, the color changes to brown, blue, gold, red and green. As the oxidative coloring treatment, there are other methods such as a heating oxidization method and a chemical oxidization method, and any method may be used as long as the surface is oxidatively colored.

Although not shown, a pattern may be formed by masking a part of the surface when forming the oxidative coloring film. Further, an embossed pattern 12 or the like having a pattern is formed near the surface of the scoop when pressing the molding die. Then, as shown in FIG. 5 (a), after the oxidative coloring process is performed and the oxide film 11 is formed, the convex surface is polished to scrape the oxidative colored film surface of the convex surface, leaving the oxidative colored film on the concave surface and leaving the oxidative coloring residue Form surface 7, FIG.
(B) It is also possible to express the pattern clearly and to make the oxidative coloring film less likely to be damaged.

The scoop of the present invention uses titanium or a titanium alloy as a material, for example, Ti-6.
When a titanium alloy of A1-4V is used, the thermal conductivity (c
Al / cm2 / sec / ° C / cm) is 0.0145 for titanium alloy, 0.145 for iron, 0.039 for stainless steel, and 0.923 for copper. It is about 1/2, and titanium or titanium alloy does not have a metallic odor or taste peculiar to metal, and therefore does not impair the odor or taste of food.

[0008]

EFFECTS OF THE INVENTION The scoop of titanium or titanium alloy of the present invention uses titanium or titanium alloy as the material, so it is light and has low thermal conductivity.
Since there is no metallic odor peculiar to metal, it does not impair the odor and taste of food, and an integrated type or a hollow integrated type gripping part makes it easy to wash and provides a durable and hard-to-break scoop. For this reason, it will lead to the solution of problems such as school lunches and elementary and junior high school meals where environmental hormones and hygiene management are important. In addition, when at least the scooping plate portion is embossed, it is difficult for rice to stick to the rice and it becomes easy to handle. Furthermore, by subjecting the surface to oxidative coloring, antibacterial action is also exhibited, and a more hygienic and colorful rice scoop can be made. Therefore, the enjoyment of meals is expected to double.
