Description

  The present invention relates to a non-adhesive rice scoop and a method for producing rice scoop.

  Traditionally rice scoop is used when you eat rice. In the old days, wooden rice scoops were used, but today, rice scoops using polypropylene moldings are also used. A problem when using rice scoop is that the rice sticks to the rice scoop, and in order to solve this problem, for example, the rice scoop is soaked in water. Moreover, the member which gave the fluororesin to the metal is also used.

  On the other hand, a rice scoop that is provided with irregularities of about 0.5 mm to 1.0 mm on the surface of the rice scoop to prevent the rice from adhering to the rice scoop or a rice scoop disclosed in Patent Document 1 has been proposed. The rice scoop disclosed in Patent Document 1 is composed of a main body and a handle, the main body is porous, and the main body is breathable so that rice does not stick to the main body.

  However, the conventional rice paddle has the following problems. For example, a scoop that uses a member obtained by applying a fluororesin to a metal is expensive and not practical in terms of strength. In addition, rice balls cannot be reliably served in a bowl with rice cake made of a porous body.

  Therefore, the present invention provides a rice scoop that can reliably and reliably serve rice in a tea bowl, and a method for producing such rice scoop.

  According to the first aspect of the present invention, the metal material molded into a scoop shape by molding means, the fluorine material applied to the surface of the metal material, and the metal molded into the scoop shape This can be accomplished by providing a scoop comprising a protective material secured to the peripheral edge of the material.

  Here, the molding means is, for example, press molding described in claim 2 or mold molding described in claim 3. The metal material is, for example, aluminum described in claim 4.

  The fluorine material is coated on the surface of a metal material, or provided by caulking or the like. Furthermore, the protective material fixed to the peripheral end portion of the metal material is made of a material such as a resin such as polypropylene, wood, or bamboo.

  By comprising in this way, when using a rice paddle, the protective material fixed to the peripheral end part protects the fluorine processing in the rice cooker, and does not damage the fluorine processing. In addition, the fluorine material provided on the surface of rice paddies prevents the sticking of rice, so that the rice can be efficiently served in a teacup.

  According to a fifth aspect of the present invention, in the first, second, third, or fourth aspect, the peripheral end portion to which the protective material is fixed is provided with a recess in the entire circumference or a part thereof, and the protective material is provided in the concave portion It is the structure where is attached.

By comprising in this way, a protective material can be reliably fixed and attached to a scoop.
According to a sixth aspect of the present invention, in the fifth aspect of the present invention, the concave portion is not more than ½ of the thickness of the scoop from the plane of the scoop. According to a seventh aspect of the present invention, the depth of the recess is not more than twice the maximum thickness of the rice paddle.

By comprising in this way, a protective material can be fixed to a scoop more reliably.
According to the invention described in claim 8, the object is to form a metal material into a scoop shape, to treat the surface of the molded scoop with a fluorine material, and to protect the peripheral edge of the scoop This can be achieved by providing a method for manufacturing rice scoops that performs the process of fixing.

  This example is an invention of a method for producing rice scoop, and by using rice scoop produced by such a production method, the protective material fixed to the peripheral edge protects the fluorine processing in the rice cooker, and The fluorine material provided on the surface of rice paddies can prevent the rice from sticking.

As explained above, if the rice scoop produced by the rice scoop and the rice scoop production method of the present invention is used, there is no stickiness of rice and rice can be served well.
Moreover, the fluorine processing of the rice cooker is not damaged, and the price of rice scoop can be suppressed as compared with the conventional one.

Hereinafter, the rice scoop of this invention and the manufacturing method of a rice scoop will be described.
FIG. 1 is a diagram showing an external configuration of the rice scoop according to the present embodiment. FIG. 1 (a) is a plan view of the rice scoop of this example, and FIG. 1 (b) is a side view. In FIGS. 1A and 1B, the rice scoop 1 uses a metal material as a base material, and in this example, aluminum is used as the metal material.

  Further, a concave portion 3 is formed along the peripheral end portion 2 in the peripheral end portion 2 of the rice paddle 1, and a resin 4 such as polypropylene is attached to the concave portion 3. In addition, the surface of the rice scoop 1 is coated with a fluorine material, so that the rice does not stick to the rice scoop 1 when the rice scoop 1 is used. Hereinafter, the manufacturing method of the rice scoop 1 of this example is demonstrated.

  First, an aluminum solution is poured into a mold to create a prototype of the rice scoop 1 having the shape shown in the figure. Note that an aluminum plate having a predetermined plate thickness may be pressed. In this case, burrs appearing on the end face are removed.

  Next, an anodic oxide film treatment is performed on the base material composed of aluminum to form an aluminum oxide film (alumite layer) on the surface of the base material. By this treatment, a porous oxide film having high electrical insulation and wear resistance is formed on the aluminum surface.

  Next, fluorine coating is performed, and a fluorine material is coated on the surface of the alumite. In this case, for example, a fluororesin such as PTFE (polytetrafluoroethylene) or PFA (tetrafluoroethylene / perfluoroalkyl vinyl ether copolymer) is used.

  Next, a resin such as polypropylene (PP) is formed in the recess 3 formed in the peripheral end 2. FIG. 2 is a cross-sectional view of the peripheral end 2, and a resin such as polypropylene is provided in the peripheral end 2 and the recess 3. Propylene is obtained by thermal decomposition of liquefied petroleum gas (LPG) or naphtha, and polypropylene (PP) is a polymer thereof, and is excellent in chemical resistance, heat resistance, and wear resistance.

  Therefore, by using a resin such as polypropylene having the above characteristics at the peripheral end of the scoop 1, the rice in the high-temperature rice cooker can be served in the bowl without causing a chemical change. Moreover, the resin such as polypropylene is used at the tip of the rice scoop 1 so that the fluorine processing in the rice cooker is not damaged.

Furthermore, since resin, such as a polypropylene, is formed in the recessed part 3 of the peripheral edge part 2, it is fixed reliably and does not come off.
Moreover, the surface of rice scoop 1 is coated with a fluororesin as described above, so that the rice does not stick to the rice scoop 1 and rice can be served well.

In the above example, a resin such as polypropylene is used as a protective material. However, a material such as wood or bamboo may be provided.
FIG. 3 shows a modification of the present invention in which a resin such as polypropylene is disposed at the tip of the rice paddle 1 and the coating of the fluorine material is omitted. Even if comprised in this way, resin, such as a polypropylene, is used for the front-end | tip part of the rice scoop 1, and the fluorine process in a rice cooker is not damaged. Moreover, since resin, such as a polypropylene, is formed in the recessed part 3 of the peripheral edge part 2, it is fixed reliably.

It is a figure which shows the external appearance structure of the rice scoop of this embodiment, (a) is a top view of the rice scoop of this example, (b) is a side view. It is sectional drawing of the peripheral edge part of rice paddle. It is a block diagram of the peripheral edge part of the rice paddle explaining the modification of this invention.
