そして、本発明は、器外方側素地部(3)の外表面をグレーズコーティング層(5)で覆って卵殻粉を外方に非表出にしたことが良好である。
(Invention of claim 2)
Then, in the present invention, it is good that the outer surface of the base portion (3) on the outer side of the vessel is covered with the glaze coating layer (5) so that the eggshell powder is not exposed to the outside.

(請求項1の発明の効果)
請求項1の発明によれば、器外方側素地部に含まれる卵殻粉を器の盛り側の空間に対して非表出となる。即ち、食材などを盛る側に卵殻粉が直接的に表出しないようになる。そして、器内方側をメラミン樹脂の素地からなるものとしているので、メラミン樹脂以外の素地素材が存在することによる強度低下や耐熱性の低下を生じさせないという優れた効果を奏するものである。
(Effect of the invention of claim 1)
According to the invention of claim 1, the eggshell powder contained in the base portion on the outer side of the vessel is not exposed to the space on the filling side of the vessel. That is, the eggshell powder does not appear directly on the side where the ingredients are placed. Since the inner side of the vessel is made of a melamine resin base material, the presence of a base material other than the melamine resin does not cause a decrease in strength or heat resistance, which is an excellent effect.

(請求項2の発明の効果)

(Effect of the invention of claim 2)
According to the invention of claim 2, since the base material on the outer side of the vessel is covered with a glaze coating layer to hide the eggshell powder from the outside, the eggshell powder affects the feeling when the outer surface of the vessel is touched. Does not reach. Therefore, the ratio of eggshell powder to be included can be freely set in the base material on the outer side of the vessel.

本発明に係る卵殻粉含有食器の一例を示す説明図である。It is explanatory drawing which shows an example of the tableware containing eggshell powder which concerns on this invention. 一例の一部断面を拡大して示す説明図である。It is explanatory drawing which shows the partial cross section of an example enlarged.

つぎに本発明を図1と図2に示す実施の形態に基づいて説明する。図中1は小皿の形態を呈した卵殻粉含有食器である。この卵殻粉含有食器1は、器内方側素地部2の外面側に器外方側素地部3を積層した構造を有している。 Next, the present invention will be described based on the embodiments shown in FIGS. 1 and 2. In the figure, 1 is an eggshell powder-containing tableware in the form of a small plate. The eggshell powder-containing tableware 1 has a structure in which the base portion 3 on the outer side of the vessel is laminated on the outer surface side of the base portion 2 on the inner side of the vessel.

卵殻粉含有食器1は、メラミン樹脂を成形素材として器内方側素地部2を圧縮成形している。そして、先成形された器内方側素地部2を金型に配置し、後述の成形素材を器内方側素地部2の所要位置に配置した状態で圧縮成形を行なっている。よって、器内方側素地部2の外面側に器外方側素地部3が積層した状態にして器内方側素地2と器外方側素地部3とが一体となった食器素地4が成形されている。 In the eggshell powder-containing tableware 1, the base portion 2 on the inner side of the vessel is compression-molded using melamine resin as a molding material. Then, the pre-molded inner base portion 2 of the vessel is placed in the mold, and the molding material described later is placed at the required position of the inner base portion 2 of the vessel, and compression molding is performed. Therefore, the tableware base 4 in which the inner side base 2 and the outer side 3 are integrated with the outer side base 3 laminated on the outer surface side of the inner side base 2 It is molded.

さらに食器素地4を成形した後に、器外方側素地部3の外面側の所要位置にグレーズコーティング材を投入し、金型の型締め及び所要の加熱を行なってグレーズコーティング層5を形成している。このグレーズコーティング層5は図2に示すように器外方側素地部3の外表面を覆っている。 Further, after molding the tableware base 4, the glaze coating material is put into the required position on the outer surface side of the base portion 3 on the outer side of the vessel, and the mold is clamped and the required heating is performed to form the glaze coating layer 5. There is. As shown in FIG. 2, the glaze coating layer 5 covers the outer surface of the base portion 3 on the outer side of the vessel.

卵殻粉含有食器1の内方にはフォイル6が配置されている。フォイル6は絵付け用のフォイルであり、器内方側素地部2を成形する際、この器内方側素地部2を成形する金型に、器内方側素地部2の内表面側となるようにしてフォイル6を配置する。そして、上述したように成形素材のメラミン樹脂を前記金型の所要位置に配置してから圧縮成形する。この圧縮成形によってフォイル6を一体にした器内方側素地部2を得ている。 A foil 6 is arranged inside the tableware 1 containing eggshell powder. The foil 6 is a foil for painting, and when the inner surface side base portion 2 of the vessel is molded, the mold for forming the inner base portion 2 of the vessel is fitted with the inner surface side of the inner surface side base portion 2. The foil 6 is arranged so as to be. Then, as described above, the melamine resin as the molding material is placed at the required position of the mold, and then compression molding is performed. By this compression molding, the inner side base portion 2 in which the foil 6 is integrated is obtained.

器内方側素地部2の成形素材はメラミン樹脂材料を約10割としているのに対して、器外方側素地部3の成形素材は、卵殻粉とメラミン樹脂とを混合した材料である。そしてこの混合材料を成形素材として器外方側素地部3を圧縮成形している。 The molding material of the base portion 2 on the inner side of the vessel is made of melamine resin material at about 100%, whereas the molding material of the base portion 3 on the outer side of the vessel is a material obtained by mixing eggshell powder and melamine resin. Then, using this mixed material as a molding material, the base portion 3 on the outer side of the vessel is compression-molded.

なお、器内方側素地部3は白色としており、白色顔料が含まれているが、白色顔料は成形素材中のメラミン樹脂の配合割合を大幅に減じるものではない。通常のメラミン樹脂材料を成形材料とする圧縮成形品と同様の配合の割合にしている。 The base portion 3 on the inner side of the vessel is white and contains a white pigment, but the white pigment does not significantly reduce the mixing ratio of the melamine resin in the molding material. The mixing ratio is the same as that of the compression molded product using a normal melamine resin material as the molding material.

器内方側素地部2のメラミン樹脂配合割合に対して、器外方側素地部3の成形材料が卵殻粉とメラミン樹脂との混合材料であり、バイオプラスチックとなっていることから、器外方側素地部3ではメラミン樹脂配合割合が減じられている。 Since the molding material of the outer base part 3 of the vessel is a mixed material of eggshell powder and melamine resin with respect to the melamine resin blending ratio of the base portion 2 on the inner side of the vessel, it is a bioplastic. The melamine resin compounding ratio is reduced in the side substrate portion 3.

卵殻粉自体が白色の顔料の役割を果たすことができる。そのため、器外方側素地部3の色を白色とする場合には、他の白色顔料を用いる必要はない。 The eggshell powder itself can act as a white pigment. Therefore, when the color of the base portion 3 on the outer side of the vessel is white, it is not necessary to use another white pigment.

上述したように器外方側素地部3の外表面がグレーズコーティング層5で覆われている。そのため、グレーズコーティング層5は器外方側素地部3に含まれる卵殻粉を外方に対して非表出にしている。 As described above, the outer surface of the base portion 3 on the outer side of the vessel is covered with the glaze coating layer 5. Therefore, the glaze coating layer 5 hides the eggshell powder contained in the base portion 3 on the outer side of the vessel from the outside.

器外方側素地部3に含まれる卵殻粉がグレーズコーティング層5によって覆われているため、卵殻粉のカルシウム分は、卵殻粉含有食器1に食器洗いなどでの水分が付着しても変質しない。 Since the eggshell powder contained in the base portion 3 on the outer side of the vessel is covered with the glaze coating layer 5, the calcium content of the eggshell powder does not deteriorate even if water from dishwashing or the like adheres to the tableware 1 containing the eggshell powder.

なお、器内方側素地部2についてもグレーズコーティング層5によって覆われている。器内方側素地部2での器内表面側となる面にグレーズコーティング材を施してグレーズコーティング層を設ける点は、上記フォイル6を一体にした後や、器外方側素地部3に対してグレーズコーティング層5を設けるときの前後などに行なうようにすればよい。よって図2に示すように器外方側素地部3に対してこの器外方側素地部3での器の盛り側に、前記グレーズコーティング層5と前記器内方側素地部2との二つの層が重ねられている。 The inner substrate 2 is also covered with the glaze coating layer 5. The point that the glaze coating material is applied to the surface of the inner surface side of the vessel 2 to provide the glaze coating layer is that after the foil 6 is integrated or the outer surface of the vessel 3 is provided. This may be done before and after the glaze coating layer 5 is provided. Therefore, as shown in FIG. 2, the glaze coating layer 5 and the inner side base portion 2 of the vessel are located on the filling side of the vessel in the outer base portion 3 of the vessel with respect to the base portion 3 on the outer side of the vessel. Two layers are stacked.

上述したように卵殻粉を含んでなる器外方側素地部3はバイオプラスチック(バイオマスプラスチックbiomass−based plastic)として構成されている部分である。よって、卵殻粉含有食器1は、石油由来のプラスチックにて製造した食器に比べて、材料生成に係るCO2量が減じられた食器となっており、廃棄処理した場合でのCO2排出量を低減して、環境温暖化の防止に寄与する食器としているものである。 As described above, the outer substrate portion 3 containing eggshell powder is a portion configured as a bioplastic (biomass-based plastic). Therefore, the eggshell powder-containing tableware 1 is a tableware in which the amount of CO2 related to material production is reduced as compared with the tableware made of plastic derived from petroleum, and the amount of CO2 emissions when disposed of is reduced. Therefore, it is used as tableware that contributes to the prevention of environmental warming.
