Description

本考案は、射出成形によって成形された内側容器の周囲に射出成形よりなる透明又は半透明の外側容器を融合一体化してなる合成樹脂製の二重容器を提供するものに関する。   The present invention relates to a double container made of synthetic resin in which a transparent or translucent outer container made of injection molding is integrated around an inner container formed by injection molding.

従来より化粧料等を収納する容器は、その美観を良好とするために該容器に様々な着色や模様を施している。その手段としては、容器そのものを着色したり、容器の表面に紙片や金属箔片或いは着色塗料の付着等により着色層や装飾層を形成したりしている。また、それらの面上にコート層を形成し、それらの着色層や装飾層につやを出したり、劣化や欠落することを防止している。   Conventionally, containers for storing cosmetics and the like have been colored or patterned on the container in order to improve the appearance. As the means, the container itself is colored, or a colored layer or a decorative layer is formed on the surface of the container by attaching a piece of paper, a metal foil piece or a colored paint. In addition, a coat layer is formed on these surfaces to prevent the colored layer and the decorative layer from being glossed, and from being deteriorated or missing.

また、容器を透明或いは半透明とし、該容器の内側に着色層や装飾層を設けているものもある。   Some containers are transparent or translucent, and a colored layer or a decorative layer is provided inside the container.

更に、特開２００１−２８７２６０号公報のように、透明或いは半透明の外容器の内側表面に装飾手段を施した薄肉層の内容器を設けた二重容器も存在する。   Further, as disclosed in Japanese Patent Application Laid-Open No. 2001-287260, there is also a double container in which a thin layer inner container provided with a decoration means on the inner surface of a transparent or translucent outer container.

また、特開平７−１２５０００号公報のように、容器を二重とし、内容器と外容器の色を別々とし、該外容器側から内容器の色が可視できるようにしたものも存在する。
特開２００１−２８７２６０号公報 特開平７−１２５０００号公報 In addition, as disclosed in Japanese Patent Application Laid-Open No. 7-125000, there is a type in which the container is doubled, the inner container and the outer container have different colors, and the color of the inner container is visible from the outer container side.
JP 2001-287260 A JP 7-125000 A

上記容器の表面或いはその内側に着色層を設けたものは、たとえ容器に艶消し加飾等を施しても該着色層が平面的なため立体感に乏しいものであった。   Those provided with a colored layer on the surface of the container or on the inside of the container were poor in three-dimensionality because the colored layer was flat even if the container was subjected to matte decoration.

また、容器を二重とし、外側容器を透明或いは半透明として内側容器に施された着色層を外側から可視することにより立体感を生じさせているものは、外側容器が単に厚いコーティング層を形成しているように可視され、着色層における色の濃淡を厚さ方向で表現できるものではなかった。   Also, if the outer container is made transparent and the outer container is made transparent or semi-transparent, and the colored layer applied to the inner container is visible from the outside, the outer container simply forms a thick coating layer. The color density in the colored layer could not be expressed in the thickness direction.

本考案は、上記欠点を解決したもので、内側容器と外側容器との境界領域に内側容器に着色した色の濃淡層を厚さ方向に形成することにより同一色による奥行の生じる着色層を表現することを可能としたものである。   The present invention solves the above-mentioned drawbacks, and expresses a colored layer in which a depth of the same color is generated by forming a colored layer of a colored color in the thickness direction in the boundary region between the inner container and the outer container. It is possible to do.

具体的構成として、射出成形によって着色成形された内側容器を外側容器を成形する金型とし、該内側容器の外表面に射出成形により透明又は半透明の外側容器を成形し、該内・外側容器の材料を同一樹脂とすることにより一体化し、且つその境界領域に内側容器に着色した色の濃淡層を形成してなる合成樹脂製二重容器を特徴とする。   As a specific configuration, an inner container colored and molded by injection molding is used as a mold for molding the outer container, and a transparent or translucent outer container is molded by injection molding on the outer surface of the inner container. This is characterized by a synthetic resin double container in which the same resin is integrated to form a dark and light colored layer on the inner container in the boundary region.

また、内側容器の外表面側と外側容器の内側とが融合一体化してなる合成樹脂製二重容器を特徴とする。   Further, the present invention is characterized by a synthetic resin double container in which the outer surface side of the inner container and the inner side of the outer container are integrated.

更に、内側容器の蓋との嵌着部を除いた外側面及び外底面を外側容器で囲繞一体化してなる合成樹脂製二重容器を特徴とする。   Further, the present invention is characterized by a synthetic resin double container in which the outer surface and the outer bottom surface excluding the fitting portion with the lid of the inner container are integrally surrounded by the outer container.

また、内側容器及び外側容器を各々１ｍｍ〜５ｍｍの厚さとした合成樹脂製二重容器を特徴とする。   Further, the present invention is characterized by a synthetic resin double container in which the inner container and the outer container each have a thickness of 1 mm to 5 mm.

更に、外側容器の外表面を鏡面加工による光沢層としてなる合成樹脂製二重容器を特徴とする。   Further, the present invention is characterized by a synthetic resin double container in which the outer surface of the outer container is used as a gloss layer by mirror finishing.

本考案は、着色された内側容器の外側に融合状態で透明又は半透明の外側容器を融合一体化して二重容器を成形しているので、内側及び外側容器の各々に別々の色層を形成した二重容器とは異なり、二重容器の境界領域に内側容器に着色した濃淡層を形成することができ、立体感のある奥行の生じる着色層を容器の厚さとなる内側に形成することが可能となった。   In the present invention, a transparent or translucent outer container is fused and integrated with the outer side of the colored inner container to form a double container, so that separate color layers are formed on each of the inner and outer containers. Unlike the double container, it is possible to form a colored layer on the inner container in the boundary region of the double container, and to form a colored layer with a three-dimensional depth inside the container thickness. It has become possible.

また、内側容器と外側容器とが融合一体化されるので、その境界が不明となり、二重成形された成形物であることを判別することができず、その境界に空気層が生じることもなく、且つ内側及び外側容器が分離することのおそれがない二重容器が可能となった。   In addition, since the inner container and the outer container are fused and integrated, the boundary is unclear, it cannot be determined that the molded product is double-molded, and an air layer is not generated at the boundary. And the double container which does not have a possibility that an inner side and an outer side container may isolate | separate was attained.

更に、内側及び外側容器の容器厚を厚くすることにより、重量感を出し、且つ、内側の着色層から外側に向かってその色の薄くなった色層及び透明又は半透明の層へと変化する奥行の深い色層を有する容器を提供することが可能となった。   Furthermore, by increasing the container thickness of the inner and outer containers, the weight is increased, and the color layer of the inner and outer containers is changed from the inner colored layer toward the outer side, and the color layer becomes thinner and transparent or translucent. It has become possible to provide a container having a deep color layer.

以下、本考案の合成樹脂製二重容器を図面に沿って説明する。   Hereinafter, the synthetic resin double container of the present invention will be described with reference to the drawings.

図１は、本考案の合成樹脂製二重容器の蓋を除いた状態の正面図、図２は同平面図及び図３は同底面図である。
合成樹脂製二重容器１は、化粧料等を収納する容器で、図４の断面図に示すように、内側容器２に融合状態で外側容器３を一体化して成るものである。 FIG. 1 is a front view showing a state in which the lid of the synthetic resin double container of the present invention is removed, FIG. 2 is a plan view thereof, and FIG. 3 is a bottom view thereof.
The synthetic resin double container 1 is a container for storing cosmetics and the like, and is formed by integrating the outer container 3 in an integrated state with the inner container 2 as shown in the sectional view of FIG.

内側容器２は、底部４と側壁部５とよりなる上方が開放した筒状或いは様々な形状をした容器で、その上端部には蓋（不図示）を嵌合するための螺合嵌着等の嵌着部６を構成している。   The inner container 2 is a cylindrical or various container having an open upper portion composed of a bottom portion 4 and a side wall portion 5, and a screw fitting for fitting a lid (not shown) to the upper end portion thereof. The fitting part 6 is comprised.

該内側容器２には、上記嵌着部６の下端部から側壁部５及び底部４へ渡って外側容器３を融合一体化している。
図５に示すように、該外側容器３の上端部は、内側容器２の蓋を取着するために薄く形成した嵌着部６のための凹部７の下端基部へ巻き込み係止するようにして内側へ折り曲げた折曲部８を形成して一体化している。 In the inner container 2, the outer container 3 is integrated and integrated from the lower end portion of the fitting portion 6 to the side wall portion 5 and the bottom portion 4.
As shown in FIG. 5, the upper end portion of the outer container 3 is entangled and locked to the lower end base portion of the recess portion 7 for the fitting portion 6 formed thinly for attaching the lid of the inner container 2. A bent portion 8 bent inward is formed and integrated.

また、外側容器３は、内側容器２の側壁部５及び周縁部を外方へ突出形成して厚くした膨出部９を有する底部４の凹凸に沿うようにして融合一体化されている。上記内側容器２と外側容器３とは融合した状態で一体的に形成されている。   In addition, the outer container 3 is integrated and integrated along the unevenness of the bottom part 4 having the bulging part 9 that is formed by protruding the side wall part 5 and the peripheral part of the inner container 2 outwardly. The inner container 2 and the outer container 3 are integrally formed in a fused state.

また、上記内側容器２は、既存の着色材料を使用して合成樹脂の射出成形によって成形される。該射出成形によって金型から取り出された該内側容器２は、外側容器３を射出成形する金型として装着され、該外側容器３の内側を形成する金型の役割を成す。   The inner container 2 is formed by injection molding of a synthetic resin using an existing coloring material. The inner container 2 taken out from the mold by the injection molding is mounted as a mold for injection molding the outer container 3 and serves as a mold for forming the inside of the outer container 3.

上記射出成形機に装填された内側容器２の表面と他の金型との間に合成樹脂を充填し、外側容器３を成形する。上記外側容器３の合成樹脂材料は、該内側容器２の材料と同一であり、且つ透明或いは半透明とする。   A synthetic resin is filled between the surface of the inner container 2 loaded in the injection molding machine and another mold to mold the outer container 3. The synthetic resin material of the outer container 3 is the same as the material of the inner container 2 and is transparent or translucent.

上記射出成形により内側容器２を成形した樹脂と外側容器３を成形した樹脂とはその外表面及び内表面において射出成形時における熱により互いに溶け合い、双方が混合して融合状態となる。   The resin formed from the inner container 2 by the injection molding and the resin formed from the outer container 3 are melted together by heat at the time of injection molding on the outer surface and the inner surface, and both are mixed to form a fused state.

上記合成樹脂の二重容器の製造により内側容器２の着色部分が透明又は半透明の外側容器３側へ入り込み、内側容器の外方側の境界領域において内側容器側から外側容器側へかけて着色状態が薄くなる濃淡層が生じることになる。   The colored portion of the inner container 2 enters the transparent or translucent outer container 3 side by the production of the above-mentioned synthetic resin double container, and colors from the inner container side to the outer container side in the outer boundary region of the inner container. A light and dark layer will be produced in which the state becomes thin.

また、内側容器２と外側容器３とが融合状態で一体化されるので、外観からでは当該二重容器が内側及び外側の容器よりなる二重容器で成形されたものであることは判別することはできない状態となる。   Further, since the inner container 2 and the outer container 3 are integrated in a fused state, it is determined from the appearance that the double container is formed by a double container composed of an inner container and an outer container. Can not be.

更に、内側容器２及び外側容器３の容器厚を１ｍｍ〜５ｍｍとすることにより重量感を出すことができ、質感も得られる容器を提供することが可能となった。   Furthermore, by making the container thickness of the inner container 2 and the outer container 3 1 mm to 5 mm, it is possible to provide a container that can give a sense of weight and can also have a texture.

また、外側容器３の表面を鏡面加工とすることにより、光沢を生じさせ、更に、例えば転写、ホットスタンプ、シルク印刷、ＵＶ印刷及びシール等による二次的加飾を容易に行なうことを可能としている。   In addition, the surface of the outer container 3 is mirror-finished so that it is glossy, and further, for example, secondary decoration by transfer, hot stamping, silk printing, UV printing, sealing, etc. can be easily performed. Yes.
