Description
【0001】[0001]
本考案は各種産業分野における物品の保温,保冷や運搬などに用いる発泡コン テナに関する。 The present invention relates to a foamed container used for keeping heat, cold, and transporting articles in various industrial fields.
【0002】[0002]
従来、物品の保冷運搬,保温運搬,あるいは保管に利用されている発泡プラス チックによる成形コンテナは、軽量で断熱性,緩衝性,遮音性にすぐれ、適度の 耐久性も備えており、多くの分野で利用されている。また切断などの二次加工も 容易におこなえるなど多くの特徴を有している。 Molded containers made of foamed plastic, which have been conventionally used for cold and warm transportation of goods, or for storage, are lightweight, have excellent heat insulation, cushioning, and sound insulation, and also have appropriate durability, and are used in many fields. It is used in. It also has many features such as easy secondary processing such as cutting.
【0003】[0003]
従来、利用されている前記発泡コンテナは、以上のような利点があるが、成形 された発泡コンテナの表面は軟らかくて傷が付き易く、汚れ易いという欠点があ る。また表面は凹凸のある粗面で滑らかでないので印刷がむずかしく、ラベルな どの印刷物を貼っても剥れ易いという欠点がある。水分も発泡ビーズの隙間から 浸透する場合もある。 このような欠点を改善するため、図5に示すように発泡コンテナ100の内表 面101に対し、この内表面101に一致するような水密な成形品102を別途 ポリスチレン(PS)、ポリプロピレン(PP)などによって成形して嵌め込む ことがおこなわれている。しかし、この方法は手間がかかり、コストがかかると いう欠点がある。 本考案は、前記事情に鑑みてなされたもので、前記課題を解消した発泡コンテ ナを提供することを目的とする。 Although the foam containers that have been conventionally used have the above-mentioned advantages, they have the drawbacks that the surface of the molded foam container is soft, easily scratched, and easily soiled. In addition, since the surface is rough and uneven and is not smooth, printing is difficult and even when a printed matter such as a label is attached, it is easily peeled off. Water may also penetrate through the gaps between the foam beads. In order to improve such a defect, as shown in FIG. 5, a water-tight molded article 102 which is in conformity with the inner surface 101 of the foam container 100 is separately provided with polystyrene (PS), polypropylene (PP). ) Etc. are used to mold and fit. However, this method has the drawback that it is time-consuming and costly. The present invention has been made in view of the above circumstances, and an object thereof is to provide a foamed container that solves the above problems.
【0004】[0004]
前記目的に添い、本考案は、熱可塑性樹脂を発泡成形してなるコンテナの表面 に、該コンテナを加熱硬化した水密なスキン層を一体に有する発泡コンテナによ って前記課題を解消した。 また、本考案は、熱可塑性樹脂を発泡成形してなるコンテナの表面を分子配向 温度以上に加熱し、表面に溶融硬化した水密なスキン層を形成してなる発泡コン テナによって前記課題を解消した。 In view of the above object, the present invention solves the above-mentioned problems by a foamed container having a watertight skin layer integrally formed by heat-curing the container on the surface of a container formed by foaming a thermoplastic resin. Further, the present invention solves the above-mentioned problems by a foam container in which the surface of a container formed by foam-molding a thermoplastic resin is heated to a molecular orientation temperature or higher, and a water-tight skin layer that is melt-cured is formed on the surface. .

以下、本考案について図面を参照しながら詳細に説明する。 本考案に係る発泡コンテナの材料として、熱可塑性プラスチック材料を用いる 。たとえばポリスチレン(PS)またはポリプロピレン(PP)、またはポリス チレン(PS)とポリエチレン(PE)の共重合体を用いる。 これら材料の発泡ビーズを用い、図1に示すように一対の金型1,2の間に収 容した必要量の発泡ビーズ3を加熱圧着し成形体4を成形する。なお5は発泡ビ ーズ3の充填口を示し、蒸気は矢印Aから送入する。 金型2の表面に接している成形体4の表面の温度については、金型温度を熱変 形温度即ち、樹脂の分子配向温度(120℃〜160℃)前後まであげ、成形体 4の金型2に接触している表面のみを溶融させて図2に示すようにスキン層9を 形成する。このスキン層9の厚さは処理時間を適宜制御することによって調節す る。なお、処理温度については120℃未満では好ましいスキン層がえられず、 また160℃を超えると溶融が速くなりすぎ、生産技術的にむずかしくなる。 冷却後、離型すれば図3及び図4に示すように成形体の内外面が滑らかで硬く 水密なスキン層8,9で被覆された発泡コンテナ10,11がえられる。 この発泡コンテナの蓋についても、同じ要領でその内面にスキン層を形成すれ ば、内側の全表面にスキン層を備えた発泡コンテナがえられる。 なお、金型2のスキン層を形成する面を梨地,あるいは凹凸模様にすることに より、スキン層の表面もこれに対応した面に形成することができる。 なお、本考案は前記実施例のみに限定されるものではなく、其他の態様、たと えば前記製作方法以外の方法で発泡コンテナの表面を硬化してスキン層を形成し てもよい。 Hereinafter, the present invention will be described in detail with reference to the drawings. A thermoplastic material is used as the material of the foam container according to the present invention. For example, polystyrene (PS) or polypropylene (PP) or a copolymer of polystyrene (PS) and polyethylene (PE) is used. Using the foam beads of these materials, as shown in FIG. 1, a required amount of the foam beads 3 contained between a pair of molds 1 and 2 are thermocompression bonded to form a molded body 4. Reference numeral 5 indicates a filling port for the foam beads 3, and steam is fed in from an arrow A. Regarding the temperature of the surface of the molded body 4 that is in contact with the surface of the mold 2, the mold temperature is raised up to around the thermal deformation temperature, that is, the molecular orientation temperature of the resin (120 ° C. to 160 ° C.), Only the surface in contact with the mold 2 is melted to form the skin layer 9 as shown in FIG. The thickness of the skin layer 9 is adjusted by appropriately controlling the processing time. Regarding the treatment temperature, if the temperature is lower than 120 ° C., a preferable skin layer cannot be obtained, and if the temperature exceeds 160 ° C., the melting becomes too fast, which makes the production technique difficult. After cooling and releasing, as shown in FIGS. 3 and 4, foamed containers 10 and 11 in which the inner and outer surfaces of the molded body are covered with smooth, hard and watertight skin layers 8 and 9 are obtained. With respect to the lid of this foam container, if a skin layer is formed on the inner surface in the same manner, a foam container having a skin layer on the entire inner surface can be obtained. By forming the surface of the mold 2 on which the skin layer is formed into a satin finish or an uneven pattern, the surface of the skin layer can also be formed on the corresponding surface. It should be noted that the present invention is not limited to the above-mentioned embodiment, but the skin layer may be formed by hardening the surface of the foam container by another method, for example, by a method other than the above-mentioned manufacturing method.
【0006】[0006]
本考案に係る発泡コンテナによれば、表面が硬質かつ水密なスキン層で被覆さ れているので、傷や汚れが付きにくい。また水の浸透もない。したがって再利用 が可能となり、また水洗もできることから、発泡コンテナのリサイクルが可能と なる。 また発泡コンテナの表面への直接の印刷や、紙ラベルなどが貼り易く、かつ剥 れにくい。したがって機能的に便利になるばかりでなく外観を向上させて意匠的 な配慮をすることもできる。 さらに本考案に係る発泡コンテナにおいては、発泡成形からスキン層を形成す るまでの生産サイクルが 比較的短かくてすむという特徴がある。 According to the foam container of the present invention, since the surface is covered with the hard and watertight skin layer, scratches and stains are less likely to occur. There is also no penetration of water. Therefore, the foam container can be reused and washed with water, and the foam container can be recycled. In addition, it is easy to print directly on the surface of the foam container and to attach paper labels, etc. Therefore, not only is it functionally convenient, but it is also possible to improve the appearance and give design consideration. Furthermore, the foam container according to the present invention is characterized in that the production cycle from foam molding to formation of the skin layer can be relatively short.
