DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG.
A description will be given with reference to FIG. In these figures, reference numeral 1 denotes a rolling pin according to the present embodiment. The rolling pin is installed in parallel with a predetermined fixed structure 2 and is wound with noodles. As a result, as shown in FIG. 3, a tapered portion is formed in a hollow shape and, at one end, is inserted and fixed in a locking hole 2a formed in a fixed structure as shown in FIG. It is a schematic configuration. The 5000 series aluminum alloy used here is Mg, M

It is characterized by having relatively high strength and excellent properties such as weldability, corrosion resistance, moldability and low-temperature properties.

More specifically, the rolling pin 1 is, for example, an electric resistance welded tube made of an aluminum alloy and has an outer diameter of 8 mm to 11 mm, a wall thickness of 0.8 mm to 1 mm, and a length of 400 mm to 550 mm. The tapered portion 1a is formed at one end by drawing or the like.

In the present embodiment, anodized aluminum is applied to the surface of the noodles W to cause appropriate friction between the noodles W to be wound and prevent the noodles W from falling. 1 to ensure corrosion resistance.

The anodized film obtained by performing the alumite processing is, for example, 5 to 120 in average thickness.
It is about μm. This anodic oxide film is composed of a porous layer and a barrier layer. A barrier layer having a thickness of, for example, 8 to 180 nm is formed in contact with aluminum or an aluminum alloy material, and a porous layer having pores on its outer surface is formed. Is formed. The pores formed in the porous layer have, for example, an average diameter of about 12 to 30 nm.

After forming such an anodic oxide film, without performing a sealing treatment, in an air atmosphere, for example, at a temperature of 100 to 100 ° C.
A baking treatment is carried out at 350 ° C. for 5 to 120 minutes to remove water and sulfate ions mixed with the pores of the porous layer of the anodic oxide film. When an antibacterial agent is applied to the anodic oxide film having the cracks, the antibacterial agent impregnates the cracks in the anodic oxide film and simultaneously impregnates the pores of the porous layer with the antibacterial agent. It is possible to obtain the rolling pin 1 having an excellent anti-sono property without reacting and decomposing the antibacterial agent.

[0011] Such rolling pin 1 is specifically manufactured, for example, as follows. First, an aluminum or aluminum alloy material is prepared, and this aluminum or aluminum alloy material is, for example, anodized solution: 10 to 25% sulfuric acid aqueous solution, liquid temperature: 1 to 30 ° C., voltage: 10 to 130 V, current density Anodizing is performed under the conditions of 1 to 10 A / dm ² to form an anodized film having a porous layer, and the anodized aluminum or aluminum alloy material is sealed in an air atmosphere without sealing treatment. A baking treatment is performed at a temperature of 100 to 350 ° C. for 5 to 120 minutes to remove the anodizing solution contained in the pores of the porous layer of the anodic oxide film. Then, cracks are formed in the anodized film, and then the antibacterial agent is applied to impregnate the pores of the porous layer of the anodized film with the antibacterial agent to produce the film.

It is not necessary to limit the kind of the antimicrobial agent used here, but it is particularly preferable that the antimicrobial agent has low harm to the human body.
A, binazine and the like are particularly preferred. Since these antibacterial agents are hardly soluble in water, they are applied by dissolving them in an organic solvent such as alcohol, benzene, MEK, and methylene chloride. The coating is preferably performed not only once but also repeatedly two to three times. After the application, it is dried at 50 to 80 ° C.

As shown in FIG. 2, the rolling pin 1 according to the present embodiment having the above-described configuration has at least one tapered portion 1a formed at one end and a locking hole formed in the fixed structure 2. 2a.

Then, by using a 5000-series aluminum alloy, an appropriate hardness is obtained, and the aluminum alloy is prevented from being bent by the weight of the wound noodle W, and is extruded by using an electric resistance welded tube. Compared to the tube formed by the above, the rolling pin 1 can be made thinner and lighter. Further, as described above, by performing alumite processing on the surface, the deterioration of the rolling pin 1 is suppressed, and the property change is further suppressed, and the friction with the wound noodle W is appropriately maintained. While preventing the fall of W, in the hand-rolling work to give a moderate friction to the noodles W,
Smooth work is performed. Furthermore, by forming an anodic oxide film having a porous layer on the surface, and impregnating the pores of the porous layer with an antibacterial agent, the resulting material has excellent antibacterial properties, and a more sanitary rolling pin 1 and Become. Furthermore,
By forming the rolling pin 1 from an aluminum alloy, recycling becomes possible.

In the above-described embodiment, the example in which the tapered portion 1a is formed by drawing one end of the rolling pin 1 is shown. Instead, as shown in FIG. A configuration in which the end member 5 formed of a synthetic resin or metal and having a tapered tip is inserted into one end of the straight tube, and one end of the rolling pin 4 is integrated by caulking. It is also possible. With such a configuration, it is possible to use the low friction coefficient of the end member 5 to smoothly mount the end member 5 to the fixed structure 2. As shown in FIG. 6, by attaching the end members 5 to both ends of the rolling pin 6, it is possible to prevent foreign substances from entering the inside of the rolling pin 6, thereby improving hygiene.
