Description
本発明は色調変化を現出させた合成樹脂製容器に関する。 The present invention relates to a synthetic resin container that exhibits a change in color tone.
合成樹脂製容器は従来より種々の用途に使用されているが、特に容器の装飾性が商品力の大きな部分を占める化粧料用、シャンプー用等の容器においては、塗装、印刷、ラベルの貼付等により装飾性を発揮させ、他社製品と差別化するようにしている。 Synthetic resin containers have been used for various purposes in the past, especially for cosmetics and shampoo containers where the decorativeness of the container is a major part of the product, painting, printing, labeling, etc. To showcase its decorativeness and differentiate it from other companies' products.
また、容器本体自体を着色により装飾する方法も各種試みられており、たとえば、特許文献1には内層樹脂と外層樹脂の間に着色層を間欠的に円筒状に積層したプリフォームを射出成形し、このプリフォームを2軸延伸ブロー成形して着色領域が円環状に展開した容器に係る記載がある。
本発明は、色調の変化をより高度に現出させることを課題とし、今までにない装飾性を有した合成樹脂製容器を提供することを目的とするものである。 An object of the present invention is to provide a synthetic resin container having an unprecedented decorative property, with the object of making the change in color tone appear to a higher degree.
上記技術的課題を解決する本発明の内、請求項1記載の発明の手段は、
筒状の押出成形による中間体から成形される合成樹脂製容器において、
少なくとも2つの色調の異なる層を積層した積層構造を有すること、
2つの層の少なくとも一方の層厚を周方向に変化させて、この層厚の変化により周方向にグラデーション状の色調変化を現出させたこと、にある。
なおここで、本願では色調とは顔料や染料の分散により現出する色彩およびその濃淡の他にも、合成樹脂の結晶化の程度、あるいはフィラーの分散による視覚効果等を含むものとする。
Among the present invention for solving the above technical problems, the means of the invention according to claim 1 is:
In a synthetic resin container molded from an intermediate body by cylindrical extrusion,
Having a laminated structure in which at least two layers having different color tones are laminated;
The thickness of at least one of the two layers is changed in the circumferential direction, and the change in the layer thickness causes a gradation-like color tone change to appear in the circumferential direction.
Here, in this application, the color tone includes not only the color that appears due to the dispersion of pigments and dyes and the light and shade thereof, but also the degree of crystallization of the synthetic resin, the visual effect due to the dispersion of the filler, and the like.
請求項1記載の上記構成により、色調の異なる2つの層の少なくとも一方の層厚を周方向に変化させることにより、この層厚の変化により周方向のグラデーション状の色調変化により、今までにない特徴的な色調変化を現出した合成樹脂製容器を提供することができる。 By changing the thickness of at least one of the two layers having different color tones in the circumferential direction according to the above-described configuration according to claim 1, the change in the layer thickness causes a change in the color tone in the circumferential direction. A synthetic resin container exhibiting a characteristic color tone change can be provided.
そして本発明の容器は、ブロー成形のための管状パリソンや、押出しチューブ体等の筒状の押出成形による中間体から成形されるものであり、多層共押出し成形用ダイスを用いてこれら筒状の中間体を押出成形する際に、所定の層を形成する流路のクリアランスを周方向に変化させることにより、所定の層の層厚を周方向に変化させることができる。 The container of the present invention is formed from a tubular parison for blow molding, or an intermediate body by tubular extrusion molding such as an extruded tube body, and these tubular shapes are formed using a multilayer coextrusion die. When extruding the intermediate body, the thickness of the predetermined layer can be changed in the circumferential direction by changing the clearance of the flow path forming the predetermined layer in the circumferential direction.
ここで、層構成は、その層数を少なくとも2層とする中で様々なバリエーションとすることができる。また、たとえば2層の場合にはその中の1層は、必ずしも全周に亘って積層する必要はなく、半周、1/4周等、周方向に部分的に積層させることもできる。 Here, the layer configuration can be variously varied while the number of layers is at least two. For example, in the case of two layers, one of the layers is not necessarily laminated over the entire circumference, and may be partially laminated in the circumferential direction, such as a half circumference or a quarter circumference.
色調の変化は、各層の周方向への層厚変化を組み合わせることにより、様々なバリエーションで現出させることができるが、不透明な層があるとこの層によってその内側にある層の色調は外部からは視覚し得ないので、内側の層の色調やその変化を利用してグラデーション状の色調変化を現出させるためには、外側の層を透明性、あるいは半透明性とする。 The change in color tone can be manifested in various variations by combining the change in the layer thickness in the circumferential direction of each layer, but if there is an opaque layer, the color tone of the layer inside it will be externally Is not visible, so that the outer layer is made transparent or semi-transparent in order to make a gradation-like color change appear by using the inner layer's color tone or its change.
また、1つの層だけが周方向へ層厚が変化する構成とすることもできるし、たとえば外層と内層からなるもので、全体の層厚は一定で、外層と内層の層厚比を変化させるような構成とすることもできる。
また、1つの層だけを着色することもできるし、2つの層、あるいはさらに多数の層を着色して複雑な色調の変化を現出することもできる。
そして顔料や染料による着色だけでなく、フィラーを分散させて乳白状や、光を反射させるような視覚効果が周方向にグラデーション状に変化するようにすることもできる。
Further, only one layer can be configured such that the layer thickness varies in the circumferential direction, and is composed of, for example, an outer layer and an inner layer, the entire layer thickness is constant, and the layer thickness ratio between the outer layer and the inner layer is changed. It can also be set as such a structure.
In addition, only one layer can be colored, or two layers or a larger number of layers can be colored to reveal a complicated color change.
In addition to coloring with pigments and dyes, fillers can be dispersed so that a milky white shape or a visual effect that reflects light changes in a gradation shape in the circumferential direction.
また、色調のグラデーション状の変化は全周に亘って単調に現出させることもできるし、グラデーション状の変化を周期的に現出させることもできる。 Further, the gradation change of the color tone can be monotonously appearing over the entire circumference, or the gradation change can be periodically appearing.
請求項2記載の発明の手段は、請求項1記載の発明において、色調の異なる2つの層を積層し、一方の層の層厚比が正面から背面にかけて単調に減少する構成とすること、にある。 According to a second aspect of the present invention, in the invention according to the first aspect, two layers having different color tones are laminated, and the layer thickness ratio of one layer decreases monotonously from the front to the back. is there.
請求項2記載の上記構成により、正面から背面にかけて色調がグラデーション状に単調に変化する今までにない容器を提供することができる。 According to the above configuration of the second aspect, it is possible to provide an unprecedented container whose color tone changes monotonously in a gradation from the front to the back.
請求項3記載の発明の手段は、請求項1または2記載の発明において、合成樹脂製容器をブロー成形容器とすること、にある。 According to a third aspect of the present invention, in the first or second aspect of the invention, the synthetic resin container is a blow molded container.
請求項3記載の構成により、周方向のグラデーション状の色調変化により、今までにない特徴的な色調変化を現出したブロー成形容器を提供することができる。 According to the third aspect of the present invention, it is possible to provide a blow-molded container that exhibits an unprecedented characteristic color tone change due to a gradation-like color tone change in the circumferential direction.
請求項4記載の発明の手段は、請求項1または2記載の発明において、合成樹脂製容器をチューブ容器とすること、にある。 The means of the invention described in claim 4 is that, in the invention described in claim 1 or 2, the synthetic resin container is a tube container.
請求項4記載の構成により、周方向のグラデーション状の色調変化により、今までにない特徴的な色調変化を現出したチューブ容器を提供することができる。 According to the fourth aspect of the present invention, it is possible to provide a tube container that exhibits an unprecedented color tone change due to a gradation-like color tone change in the circumferential direction.

以下、本発明の実施の形態を実施例に沿って、図面を参照しながら説明する。
図1は、本発明による合成樹脂製容器の一実施例であるブロー成形容器の側面図である。図2は図1中のA−A線に沿って示す平断面図である。
この容器1は口筒部4、肩部5、円筒状の胴部6そして底部7を有するブロー成形による壜体であり、外層2と内層3を全周に亘って積層した積層構造を有する。
DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described along examples with reference to the drawings.
FIG. 1 is a side view of a blow molded container which is an embodiment of a synthetic resin container according to the present invention. FIG. 2 is a plan sectional view taken along line AA in FIG.
This container 1 is a blow molded casing having a mouth tube part 4, a shoulder part 5, a cylindrical body part 6 and a bottom part 7, and has a laminated structure in which the outer layer 2 and the inner layer 3 are laminated over the entire circumference.
外層2と内層3は共にポリプロピレン樹脂製の透明性を有する層であり、外層2はオレンジ色、内層3は黄色に着色したものである。
そして、図2の平断面図に示されるように、全周に亘って胴部6の肉厚は一定であるが、外層2の層厚が正面F部分から背面B部分にかけて単調に減少するようにしており、このような両層の層厚比の単調な変化に応じて、正面Fのオレンジ色から背面Bの黄色までその色調がグラデーション状に単調に変化して視覚される(図1参照)。
図1では黒い部分がオレンジ色、白い部分が黄色い部分を表すようにしている。なお、この図1では作画の都合で色調が段階状に変化しているように描かれているが実際には無段階にスムーズに色調が変化している。
Both the outer layer 2 and the inner layer 3 are made of polypropylene resin and have transparency, and the outer layer 2 is colored orange and the inner layer 3 is colored yellow.
As shown in the plan sectional view of FIG. 2, the thickness of the body 6 is constant over the entire circumference, but the thickness of the outer layer 2 is monotonously decreased from the front F portion to the back B portion. In accordance with such a monotonous change in the layer thickness ratio of both layers, the color tone is monotonously changed in a gradation from the orange color on the front F to the yellow color on the back B (see FIG. 1). ).
In FIG. 1, the black portion represents an orange color and the white portion represents a yellow color portion. In FIG. 1, the color tone is depicted as changing stepwise for convenience of drawing, but actually the color tone changes smoothly and steplessly.
本実施例のブロー成形容器は、多層共押出し成形用ダイスを用い、同心状に配設された円筒状流路で外層2と内層3を形成した後に、両層を合流させて外層2と内層3を積層した管状の積層パリソンをブロー成形したものであるが、合流点直前近傍でのそれぞれの流路のクリアランスを周方向に変化させることにより、各層の層厚を周方向に変化させることができる。 The blow-molded container of this example uses a multilayer coextrusion molding die, and after forming the outer layer 2 and the inner layer 3 in a cylindrical flow path arranged concentrically, the two layers are merged to form the outer layer 2 and the inner layer. This is a blow-molded tubular laminated parison with 3 layers, but the thickness of each layer can be changed in the circumferential direction by changing the clearance of each flow path in the vicinity of the junction just in the circumferential direction. it can.
図3は、外層2と内層3の層構成の他の例を、図2と同様の平断面で示すものであり、この例は外層2が正面F側の半周分積層した例であり、背面側の半分は内層2だけで構成されている。外層2の層厚は正面F部分から側面部分にかけて単調に減少するようにしている。 FIG. 3 shows another example of the layer structure of the outer layer 2 and the inner layer 3 in the same plane cross section as that of FIG. 2, and this example is an example in which the outer layer 2 is laminated by a half circumference on the front F side. The half on the side is composed only of the inner layer 2. The thickness of the outer layer 2 monotonously decreases from the front F portion to the side portion.
このような層構成を有するブロー成形容器は、多層共押出し成形用ダイスを用い、円筒状流路で内層3を、この円筒状流路の外側に同軸心状に配設された平断面形状が半円弧状の流路で外層2を形成した後に、両層を合流させて外層2と内層3を積層した管状の積層パリソンをブロー成形したものであるが、
合流点直前近傍のそれぞれの流路のクリアランスを周方向に変化させることにより、各層の層厚を周方向に変化させることができる。
A blow-molded container having such a layer configuration uses a multi-layer coextrusion die, and has a flat cross-sectional shape in which the inner layer 3 is disposed in a cylindrical flow path and coaxially disposed outside the cylindrical flow path. After forming the outer layer 2 with a semicircular arc-shaped channel, the two layers are merged to blow-mold a tubular laminated parison in which the outer layer 2 and the inner layer 3 are laminated.
The thickness of each layer can be changed in the circumferential direction by changing the clearance of each flow path in the vicinity immediately before the merging point in the circumferential direction.
以上、実施例に沿って本発明の実施の形態を説明したが、勿論本発明はこの実施例に限定されるものではなく、
たとえば層構成は、積層する層数、全周に亘って積層するか部分的に積層するか等も含めて、使用目的や装飾性に応じて様々なバリエーションでその構成を決めることができる。
また、ブロー成形容器の他にも、押出成形によるチューブ体を使用したチューブ容器でもこのような色調にかかるグラデーションを実現することができる。
また、顔料や染料による着色だけでなく、フィラーを分散させて乳白状や、光を反射させるような視覚効果を周方向にグラデーション状に変化させることもできる。
As mentioned above, although embodiment of this invention was described along the Example, of course, this invention is not limited to this Example,
For example, the layer configuration can be determined in various variations according to the purpose of use and decoration, including the number of layers to be stacked, whether the layers are stacked over the entire circumference, or whether the layers are stacked partially.
In addition to a blow molded container, such a gradation of color tone can be realized even in a tube container using a tube body formed by extrusion.
In addition to coloring with pigments and dyes, it is also possible to change the visual effect such as milky white by reflecting fillers and reflecting light into a gradation in the circumferential direction.
以上説明したように本発明の合成樹脂製容器は、周方向のグラデーション状の色調変化により、今までにない特徴的な色調変化有するものであり、他社製品との差別化を図る目的で広い分野での使用展開が期待される。 As described above, the synthetic resin container of the present invention has an unprecedented characteristic color change due to a gradation color change in the circumferential direction, and is used in a wide field for the purpose of differentiating from other companies' products.
