台所用品形成用樹脂材料３により構成されている。According to the present invention, the above-described object is to contain a silver ion-containing soluble glass which is made of plastics and which gradually elutes silver ions in at least the surface layer portion. This is achieved by a kitchen article made of plastics characterized by. The silver ion-containing soluble glass is preferably in the form of particles dispersed in the base plastic material in order to prevent stability during processing and escape from the resin layer. It may be contained in the constituent resin material. That is, the kitchen article made of plastics is composed of the kitchen article forming resin material 3 in which the silver ion-containing soluble glass particles 2 are mixed, as schematically shown in FIG.

菌作用を発揮することになる。The silver ion-containing soluble glass used in the plastic kitchen appliances according to the present invention for gradually eluting silver ions means that the glass has physical and chemical properties so as to have a controlled dissolution rate. It is a general term for glass whose composition has been adjusted in consideration of its characteristics, and is already known per se. Therefore, in a silver ion-containing soluble glass to which a silver compound is added, silver ions can be eluted at a constant rate determined over an arbitrary period of several hours to several years. Then, the eluted silver ions exert an antibacterial action against mold and other bacteria.

Here, if the particle size is 200 μm or more, the particles are not uniformly dispersed in the forming material. The content is preferably 0.005% to 15% by weight. If it is 0.05% or less, the antibacterial effect of silver ions becomes insufficient, and if it is 15% by weight or more, it becomes difficult to mix it into the forming material,

FIG. 2 shows an example of a molding method when the plastic kitchen utensil according to the present invention is applied as a trough. In FIG. 2, reference numerals 10 and 11 denote molds, respectively, and the molds are combined to form a molding chamber for trough molding.
Twelve are configured. The mold 10 is provided with a resin injection port 13, a nozzle 14 of an injection molding machine is connected to the resin injection port 13, and the resin injection port 13 is used to form a molding chamber.
Resin is injected into 12 in an injection manner.

２を含む樹脂材料３により構成された桶が製作される。Since the silver ion-containing soluble glass only needs to be present in the surface layer portion of the trough, the resin material 3 containing the silver ion-containing soluble glass 2 is first taken into consideration in consideration of saving the resin material containing the glass. A predetermined amount is injected into the molding chamber 12, and then the resin material 4 not containing the glass is injected into the molding chamber 12, so that the resin material 3 is pushed by the resin material 4 and the soluble glass containing silver ions is the surface layer of the tub. Therefore, the core material 4 is first placed in the molding chamber 12 and then the resin material 3 containing the silver ion-containing soluble glass is taken into consideration in order to save the resin material containing the glass. Is uniformly distributed over the entire molding chamber 12, and as shown in FIG. 3, a tub whose surface layer portion is made of a resin material 3 containing the silver ion-containing soluble glass 2 is manufactured.

る。As is clear from the above description, in the plastic kitchen articles according to the present invention, the plastic kitchen articles due to the antibacterial action of the silver ion-containing soluble glass present at least in the surface layer portion. Since mold and sterilization are prevented from breeding on the surface layer, the plastic kitchen utensils are hygienic, and they do not require a lot of nerves for cleaning, so they are healthy for a long time. Can be used for. Since the soluble glass containing silver ions used in the kitchen articles made of plastics according to the present invention is an inorganic substance, even if it comes into contact with food, it will only cause an antibacterial action and will not affect the human body. It is completely harmless, does not disperse, and has a semipermanent antibacterial action, so a safe antibacterial action is semipermanently obtained.
