Description

本考案は変色性容器に関する。詳細には、内部に収容した水分の有無を容器表面から視認可能な変色性容器に関する。   The present invention relates to a color changing container. Specifically, the present invention relates to a color-changing container in which the presence or absence of moisture contained therein can be visually recognized from the container surface.

従来、水や水分を含む土等を収容する容器として素焼きのコップや植木鉢があり、容器側面に孔をあけて、透明な板を取り付け、水分の有無を判別できるようにしたり、透明な板に水分によって色変化する物質を取り付けて水分の有無を明瞭に視覚判別できるようにした植木鉢が開示されている(例えば、特許文献1参照)。
前記容器は、容器内の水分の有無を容器外面より判別することができるとしても、孔をあけることによる容器の強度低下や孔から水が漏れ出すといった不具合を生じ易く、実用性を満足させることはできなかった。
Conventionally, there are unglazed cups and flower pots as containers that contain water and soil containing water, and a hole is made in the side of the container to attach a transparent plate so that the presence or absence of moisture can be determined. There has been disclosed a flower pot in which a substance that changes color depending on moisture is attached so that the presence or absence of moisture can be clearly discriminated (see, for example, Patent Document 1).
Even if the container can determine the presence or absence of moisture in the container from the outer surface of the container, it tends to cause problems such as a drop in strength of the container due to opening a hole and water leaking out of the hole, and satisfies the practicality. I couldn't.

前記変色性容器は、陶器により形成されてなる容器の外側面に、低屈折率顔料をバインダー樹脂と共に分散状態に固着させた吸液状態で透明又は半透明化する多孔質層を設けてなる。
前記容器は、素焼きにより形成された飲料用容器や、素焼鉢、駄温鉢、テラコッタ鉢のような植木鉢のように内部に収容した水分が容器外表面に漏出する微細な連通孔を少なくとも容器側面に有してなる。
The discolorable container is provided with a porous layer that is transparent or translucent in a liquid absorption state in which a low refractive index pigment is fixed in a dispersed state together with a binder resin on the outer surface of a container formed of earthenware.
The container has at least a fine communication hole through which moisture contained inside leaks to the outer surface of the container, such as a beverage container formed by unglazed baking, a flower pot such as a clay pot, a hot pot, and a terracotta pot. It has to.

前記容器外側面の連通孔を有する箇所には、低屈折率顔料をバインダー樹脂に分散状態に固着させた、吸液状態と非吸液状態で透明性を異にする多孔質層を設けてなる。
前記低屈折率顔料としては、珪酸及び/又は珪酸塩、バライト粉、硫酸バリウム、炭酸バリウム、炭酸カルシウム、石膏、クレー、タルク、アルミナホワイト、炭酸マグネシウム等が挙げられ、これらは屈折率が1.4〜1.8の範囲にあり、液体を吸液すると良好な透明性を示すものである。
なお、前記珪酸塩としては、珪酸アルミニウム、珪酸アルミニウムカリウム、珪酸アルミニウムナトリウム、珪酸アルミニウムカルシウム、珪酸カリウム、珪酸カルシウム、珪酸カルシウムナトリウム、珪酸ナトリウム、珪酸マグネシウム、珪酸マグネシウムカリウム等が挙げられる。
前記低屈折率顔料の粒径は特に限定されるものではないが、0.03〜10.0μmのものが好適に用いられる。
又、前記低屈折率顔料は2種以上を併用することもできる。
なお、好適に用いられる低屈折率顔料としては珪酸が挙げられる。

この点を以下に説明する。
珪酸は非晶質の無定形珪酸として製造され、その製造方法により、四塩化ケイ素等のハロゲン化ケイ素の熱分解等の気相反応を用いる乾式法によるものと、ケイ酸ナトリウム等の酸による分解等の液相反応を用いる湿式法によるものとに大別される。
乾式法珪酸と湿式法珪酸とでは構造が異なり、前記乾式法珪酸は珪酸が密に結合した構造であるのに対して、湿式法珪酸は、珪酸が縮合して長い分子配列を形成した構造部分を有している。
従って、湿式法珪酸は乾式法珪酸と比較して分子構造が粗になるため、湿式法珪酸を適用した場合、乾式法珪酸を用いた系と比較して乾燥状態における光の乱反射性に優れ、隠蔽性が大きくなるものと推察される。
又、多孔質層は水を吸液させるものであるから、湿式法珪酸は乾式法珪酸に比べて粒子表面にシラノール基として存在する水酸基が多く、親水性の度合いが大であり、好適に用いられる。
A portion having a communicating hole on the outer surface of the container is provided with a porous layer having a low refractive index pigment fixed to a binder resin in a dispersed state and having different transparency in a liquid absorbing state and a non-liquid absorbing state. .
Examples of the low refractive index pigment include silicic acid and / or silicate, barite powder, barium sulfate, barium carbonate, calcium carbonate, gypsum, clay, talc, alumina white, magnesium carbonate, and the like. It is in the range of 4 to 1.8, and exhibits good transparency when liquid is absorbed.
Examples of the silicate include aluminum silicate, aluminum potassium silicate, aluminum sodium silicate, aluminum calcium silicate, potassium silicate, calcium silicate, sodium calcium silicate, sodium silicate, magnesium silicate, and magnesium potassium silicate.

Two or more of the low refractive index pigments can be used in combination.
In addition, silicic acid is mentioned as a low refractive index pigment used suitably.
The silicic acid may be silicic acid produced by a dry process (hereinafter referred to as dry process silicic acid), but is preferably silicic acid produced by a wet process (hereinafter referred to as wet process silicic acid).
This point will be described below.
Silicic acid is produced as amorphous amorphous silicic acid, and depending on its production method, the dry method using a gas phase reaction such as thermal decomposition of silicon halide such as silicon tetrachloride and the decomposition by acid such as sodium silicate. It is roughly classified into those by a wet method using a liquid phase reaction such as.
The structure of the dry process silicic acid and that of the wet process silicic acid are different, and the dry process silicic acid has a structure in which silicic acid is closely bound, whereas the wet process silicic acid has a structure part in which a long molecular arrangement is formed by condensation of silicic acid. have.
Therefore, the wet process silicic acid has a rough molecular structure compared to the dry process silicic acid, so when applying the wet process silicic acid, the wet process silicic acid is superior in the diffused reflection of light in the dry state compared to the system using the dry process silicic acid, It is presumed that the concealment will increase.
In addition, since the porous layer absorbs water, the wet process silicic acid has more hydroxyl groups present as silanol groups on the particle surface than the dry process silicic acid, and has a high degree of hydrophilicity. It is done.

前記低屈折率顔料とバインダー樹脂の混合比率は、低屈折率顔料の種類及び性状に左右されるが、好ましくは、低屈折率顔料1質量部に対してバインダー樹脂固形分0.5〜2質量部であり、より好ましくは、0.8〜1.5質量部である。低屈折率顔料1質量部に対してバインダー樹脂固形分が0.5質量部未満の場合には、形成される多孔質層の実用的な皮膜強度を得ることが困難であり、2質量部を越える場合には、前記多孔質層内部への水の浸透性が悪くなる。
前記多孔質層は、一般的な塗膜と比較して着色剤に対するバインダー樹脂の混合比率が小さいため、十分な皮膜強度が得られ難い。そこで、前記のバインダー樹脂のうち、ナイロン樹脂又はウレタン系樹脂を用いて耐擦過強度を高めることが好ましい。
前記ウレタン系樹脂としては、ポリエステル系ウレタン樹脂、ポリカーボネート系ウレタン樹脂、ポリエーテル系ウレタン樹脂等があり、2種以上を併用することもできる。又、前記樹脂が水に乳化分散したウレタン系エマルジョン樹脂や、イオン性を有するウレタン樹脂(ウレタンアイオノマー)自体のイオン基により乳化剤を必要とすることなく自己乳化して、水中に溶解乃至分散したコロイド分散型(アイオノマー型)ウレタン樹脂を用いることもできる。
なお、前記ウレタン系樹脂は水性ウレタン系樹脂又は油性ウレタン系樹脂のいずれを用いることもできるが、水性ウレタン系樹脂、殊に、ウレタン系エマルジョン樹脂やコロイド分散型ウレタン系樹脂が好適に用いられる。
前記ウレタン系樹脂は単独で用いることもできるが、容器の種類や皮膜に必要とされる性能に応じて、他のバインダー樹脂を併用することもできる。ウレタン系樹脂以外のバインダー樹脂を併用する場合、実用的な皮膜強度を得るためには、前記多孔質層のバインダー樹脂中にウレタン系樹脂を固形分比率で30質量%以上含有させることが好ましい。
前記バインダー樹脂において、架橋性のものは任意の架橋剤を添加して架橋させることにより、さらに皮膜強度を向上させることができる。

The mixing ratio of the low refractive index pigment and the binder resin depends on the kind and properties of the low refractive index pigment, but preferably 0.5 to 2 mass of binder resin solid content with respect to 1 mass part of the low refractive index pigment. Part, more preferably 0.8 to 1.5 parts by weight. When the binder resin solid content is less than 0.5 parts by mass with respect to 1 part by mass of the low refractive index pigment, it is difficult to obtain a practical film strength of the porous layer to be formed. When exceeding, the water permeability to the inside of the porous layer is deteriorated.
Since the porous layer has a smaller mixing ratio of the binder resin to the colorant than a general coating film, it is difficult to obtain sufficient film strength. Therefore, among the binder resins, it is preferable to increase the scratch resistance using a nylon resin or a urethane resin.
Examples of the urethane resin include a polyester urethane resin, a polycarbonate urethane resin, and a polyether urethane resin, and two or more of them can be used in combination. In addition, a urethane emulsion resin in which the resin is emulsified and dispersed in water, or a colloid in which the resin is self-emulsified without the need for an emulsifier by an ionic group of the ionic urethane resin (urethane ionomer) itself and dissolved or dispersed in water. A dispersion type (ionomer type) urethane resin can also be used.
The urethane resin may be either a water-based urethane resin or an oil-based urethane resin, but a water-based urethane resin, in particular, a urethane emulsion resin or a colloidally dispersed urethane resin is preferably used.
The urethane resin can be used alone, but other binder resins can be used in combination depending on the type of container and the performance required for the coating. When a binder resin other than a urethane resin is used in combination, in order to obtain a practical film strength, it is preferable to contain a urethane resin in a solid content ratio of 30% by mass or more in the binder resin of the porous layer.
In the binder resin, the crosslinkable resin can be further improved in film strength by adding an arbitrary crosslinking agent and crosslinking.
The binder resin has a large or small affinity with water. By combining these, the penetration time into the porous layer, the degree of penetration, and the slow speed of drying after the penetration can be adjusted. Furthermore, the said adjustment can be controlled by adding a dispersing agent suitably.
A colorant may be contained in the porous layer.

前記多孔質層は、公知の手段、例えば、スクリーン印刷、オフセット印刷、グラビヤ印刷、コーター、タンポ印刷、転写等の印刷手段、刷毛塗り、スプレー塗装、静電塗装、電着塗装、流し塗り、ローラー塗り、浸漬塗装等により形成できる。
また、前記多孔質層中に着色剤を含有させたり、支持体と多孔質層の間に着色剤を含む水透過性の非変色層を設けることもできる。
前記支持体と多孔質層の間に設けられる非変色層は、容器とは異なる色の有色着色剤を含有させることにより、多孔質層が吸液した状態で容器の色とは異なる非変色層による色を視認でき、内部に収容した水分の有無を明瞭に視覚判別することができる。
The porous layer is a known means such as screen printing, offset printing, gravure printing, coater, tampo printing, transfer printing, brush coating, spray coating, electrostatic coating, electrodeposition coating, flow coating, roller It can be formed by coating, dip coating or the like.
Moreover, a colorant can be contained in the porous layer, or a water-permeable non-discoloring layer containing a colorant can be provided between the support and the porous layer.
The non-discoloring layer provided between the support and the porous layer contains a colored colorant having a color different from that of the container, so that the non-discoloring layer is different from the color of the container in a state where the porous layer absorbs liquid. The color due to can be visually recognized, and the presence or absence of moisture contained in the interior can be clearly discriminated visually.

また、前記多孔質層には撥水性樹脂層を設けることもできる。
前記撥水性樹脂層は、シリコン系、パラフィン系、ポリエチレン系、アルキルエチレン尿素系、フッ素系等の撥水性樹脂から選ばれる撥水性樹脂を含む撥水処理液を多孔質層上に適宜形状の像を形成するよう付着させ、浸透乾燥して得られる多孔質層に内在し、共存する層である。
前記撥水性樹脂層は多孔質層の一部に内在し、共存状態に配設されているので、前記撥水性樹脂層の共存箇所の多孔質層は撥水効果により吸水状態が形成されず、不透明状態が保持される。
従って、乾燥状態では判別し難い撥水性樹脂層と多孔質層が、撥水性樹脂層の非配設部分の多孔質層への吸液により、判別可能となる。
ここで、多孔質層に共存状態に配設される撥水性樹脂層は、多孔質層の上層から容器外表面に位置する多孔質層の下層まで撥水性樹脂層が共存した状態の他、多孔質層の上層から多孔質層の中間層まで撥水性樹脂層が共存した状態、多孔質層の中間層に撥水性樹脂層が共存した状態、多孔質層の中間層から多孔質層の下層まで撥水性樹脂層が共存した状態が挙げられる。
The porous layer may be provided with a water repellent resin layer.
The water-repellent resin layer is formed by appropriately forming an image of a water-repellent treatment liquid containing a water-repellent resin containing a water-repellent resin selected from silicon-based, paraffin-based, polyethylene-based, alkylethyleneurea-based, and fluorine-based water-repellent resins on a porous layer. It is a layer that is inherent to and coexists in the porous layer obtained by adhering so as to form and osmotically drying.
Since the water-repellent resin layer is inherent in a part of the porous layer and disposed in a coexisting state, the water-absorbing state is not formed in the porous layer at the coexisting location of the water-repellent resin layer, The opaque state is maintained.
Accordingly, the water-repellent resin layer and the porous layer that are difficult to discriminate in the dry state can be discriminated by absorbing liquid into the porous layer at the non-arranged portion of the water-repellent resin layer.
Here, the water-repellent resin layer disposed in the coexistence state in the porous layer is a porous layer in addition to the state in which the water-repellent resin layer coexists from the upper layer of the porous layer to the lower layer of the porous layer located on the outer surface of the container. The water repellent resin layer coexists from the upper layer of the porous layer to the intermediate layer of the porous layer, the water repellent resin layer coexists in the intermediate layer of the porous layer, from the intermediate layer of the porous layer to the lower layer of the porous layer A state where the water-repellent resin layer coexists is mentioned.

更に、前記多孔質層中に透明性芯物質を金属酸化物で被覆した透明性金属光沢顔料やカラーフロップ性を有する透明性金属光沢顔料を含有させて乾燥状態においては低屈折率顔料による色が視認されると共に、吸液状態では透明性金属光沢顔料による金属光沢色が視認される変色性容器を得ることもできる。
前記透明性金属光沢顔料としては、天然雲母、合成雲母、ガラス、アルミナを芯物質とし、その表面にチタン、ジルコニウム、クロム、バナジウム、鉄等の金属酸化物を被覆した顔料が挙げられる。
前記、カラーフロップ性を有する透明性金属光沢顔料としては、コレステリック液晶型透明性金属光沢顔料、酸化珪素を1種又は2種以上の金属酸化物で被覆した透明性金属光沢顔料が挙げられる。
なお、吸液状態で明瞭な金属光沢色を視認するためには、前記非変色層中に金属光沢顔料を含有させたり、金属光沢顔料を練り込んだ容器を用いることが好ましい。

Examples of the transparent metallic luster pigment include pigments in which natural mica, synthetic mica, glass, and alumina are used as core materials, and the surface thereof is coated with a metal oxide such as titanium, zirconium, chromium, vanadium, or iron.
Examples of the transparent metallic luster pigment having color flop include a cholesteric liquid crystal type transparent metallic luster pigment and a transparent metallic luster pigment in which silicon oxide is coated with one or more metal oxides.
In order to visually recognize a clear metallic luster color in the liquid absorption state, it is preferable to use a container containing a metallic luster pigment in the non-discoloring layer or kneaded with a metallic luster pigment.

更に、多孔質層中に可逆熱変色性材料や光変色性材料を含有させたり、容器と多孔質層の間に可逆熱変色性材料や光変色性材料を含む層を設けることにより、温度変化や光照射により多彩な色変化を付与することもできる。   Furthermore, by incorporating a reversible thermochromic material or photochromic material in the porous layer, or by providing a layer containing a reversible thermochromic material or photochromic material between the container and the porous layer, the temperature change Various color changes can be imparted by light irradiation.
