【発明が属する技術分野】
本発明はPET樹脂を使用し、成型した加工品に関するものである。
【0002】
【従来の技術】
従来透明樹脂といえばPC(ポリカーボネート)、PP(ポリプロピレン)、PE(ポリエチレン)、PS(ポリスチレン)が代表的な素材であり、ポリエステル樹脂であるPET(ポリエチレンテレフタレート)は流動性(成形性)が悪く、射出成型には不向きであった。従ってその透明性、耐衝撃性という優れた性能を持ちながら、真空成型やブロー成型等の加工方法により、ブリスターパックやペットボトルといった平板加工分野での波及に留まっていた。PETの射出成型はゲートや金型の温度管理によりある程度可能である(例えば、特許文献1参照)。また、透明性や耐熱性を確保する工夫も行われている(例えば、特許文献2、3、4、5参照)。
【0003】
近年流動性、耐衝撃性、透明性、耐熱性を兼ね備えたPET樹脂そのものの提案がなされている。(例えば、特許文献6及び7)

【0005】
PET樹脂を一体成型し、ヒンジを設けた製品の提案はない。
【0006】
医療器具容器のほとんどはPP、PS、PE製であり、PSは割れやすく、PP、PEは透明性に欠ける。滅菌済のものは外袋のみで包装するか、或いは外袋を二重にすることが一般的である。
【0007】
透明樹脂を成型加工した容器は大半がPC、PP、PS、PE製であり、使い捨て理化学試験器具類は容器本体がこれら樹脂製で、蓋付きの場合別部品となっている場合が多い。
【0008】
スライドグラスは透明度や価格の点で、未だ樹脂製はなく、ガラス製である。滅菌済スライドグラスも存在しない。
【0009】
レンズ、レンズ枠、サイドフレームが樹脂製で、一体成型された眼鏡は存在しない。
【0010】
垂直のつき合せガラスは中央をシリコン等のコーキングを施して密閉する必要がある。波型等の変形や模様付き、文字付きをガラスに施すには高価な加工を必要とする。
【0011】
照明器具カバーや食器は、樹脂製の場合、多くはPSやPP製の使い捨てタイプである。
【0012】
樹脂製屋根瓦にPET樹脂が使用されたことはなく、また透明色の屋根瓦も存在しない。
【0013】
樹脂製ヘルメットにPET樹脂が使用されたことはなく、また透明色のヘルメットも存在しない。
【0014】
【発明が解決しようとする課題】
PCは材料が高価であり、安価な量産品に不向きである。また硬度は確保されているが、ヒンジのような薄板形状にすると割れやすい。PP、PEは型を磨き込んでも透明度が不足する。強度が不十分で、負荷が大きくかかる製品には向かない。またPPは放射線を当てると変色、劣化する。PSは耐衝撃度が低く、落とすと割れる。PETは流動性(成形性)が悪く、射出成型には不向きであった。
【0015】
使い捨て理化学試験器具は、蓋付きの場合、別部品との組み合わせであったり、試験管キャップのように別売りである。
【0016】
スライドグラスはガラス製しか存在せず、エッジは刃が立ち危険で、落とすと割れる。蓋付きはなく、もう一枚スライドグラスを、検体を挟み込むように載せるが、位置がずれたり、検体がはみ出したりする。検体を載せる円形の窪み付きタイプは非常に高価である。滅菌済スライドグラスは存在しない。
【0017】
眼鏡は落とすと高価なレンズが割れる。軽量スチールフレームは変形しやすい。
【0018】
窓ガラスに凹凸を付けるには高価な加工が必要である。またガラスはハンマー等で簡単に割れ、防犯上好ましくない素材である。
【0019】
ガラス製の照明器具カバーや食器は衝撃に弱く、割れやすい。樹脂製は高級感に欠ける。
【0020】
瓦屋根に天窓をつけようとする際、その部分は瓦を外してアルミサッシを設置するため、瓦屋根の風情が損なわれる。ソーラーパネルを設置する場合は瓦屋根の上から設置するしか方法がないので、同様に風情が損なわれる。
【0021】
ヘルメットに用いられるABSやPP樹脂は安価で量産向きであるが、耐衝撃性に欠ける。PCは材料が高価であり、安価な量産品に不向きである。また硬度は確保されているが、薄板形状にすると割れやすい。
【0022】
【課題を解決するための手段】
本発明は共重合及びコンパウンド技術を用いて流動性を高め、射出成型を可能としたPET樹脂を用い、従来射出成型が不可能とされていた製品を具体的に形にする提案である。設計度が自由になり、透明度の高い、且つ耐衝撃性に優れた製品加工が可能となった。全体が一体成型されたヒンジ付き加工品の、ヒンジの最も薄い部分を0.2mm以上に設定することにより、柔軟性に富むPET樹脂はヒンジとして機能する。
【0023】
ヒンジ最薄部分形状の提案として、厚さ0.2mm以上の板状、線状の稜線からテーパー状に厚さを増していく形状、及び平板を円柱状に丸めた形状とする。ヒンジ最薄部分は一箇所でもよいし、複数あってもよい。これらのヒンジは適度なバネ性を確保し、本体と蓋が一体成型され、スムーズに開閉できる透明容器を提供する。
【0024】
医療用使い捨て器具を収納梱包する容器であり、廃棄の際に使用済みの器具を再度収納し、密閉し廃棄できる容器とした。この容器は、器具を収納する本体部分の上部に滅菌紙、フィルム、タイベック等の滅菌可能なシートをヒートシールすることにより密封包装とし、その上から蓋を閉じ、機密性、無菌性を高めることが可能となる。また外側全体を更に滅菌可能な袋状の包装体をヒートシールすることにより密封すると、二重包装により、機密性、無菌性は増大し、安全性が確保される。
【0025】
理化学試験で用いる試験管、メスシリンダー、液量計、ビーカー、シャーレ、コップ、採血管、ディスポセル、試薬ビン、沈殿管、遠心チューブ等の器具類は本体に内容物を入れた後、一体成型された蓋を密閉し、試験検査或いは保管が可能である。PET樹脂は放射線耐性なので、放射線滅菌済みとすることも可能である。
【0026】
検体標本を顕微鏡観察、保管するスライドグラスを、PET樹脂で射出成型した場合、長方形板表面に検体を載せる円形の窪みを容易に成型できる。ヒンジを介して一体成型されている蓋を密閉し使用することも可能である。透明度も高い。このスライドグラスも同様に滅菌が可能である。
【0027】
眼鏡はレンズとレンズ枠、及びサイドフレームをPET樹脂により一体成型する。レンズ枠とサイドフレーム間のヒンジは一体接続しており、柔軟性に富み、軽量である。安価に量産できる。
【0028】
PET樹脂原料を使用したヒンジ付き加工品を射出成型加工する場合、射出成型機の設定をシリンダー温度240℃〜285℃、射出速度を低速から中速に設定し、成型加工を行う。
【0029】
或いは、押し出し成型加工により、ヒンジ形状を形成し、押し出された材料を真空成型加工により凹凸を形成する製造方法とした。
【0030】
PET樹脂製窓ガラスは、射出成型の特性を生かし、波型や垂直のつき合せ等の変形窓、或いは模様付き、浮き出し文字付きの装飾等の特殊形状を有することを可能とする。また窓枠や取っ手及び施錠部品を窓ガラスと共に一体成型してもよい。
【0031】
PET樹脂製照明器具カバー、食器は、設計自由度が高く、耐衝撃性に優れ、透明度が高く、熱変形せず、安価となる。
【0032】
PET樹脂製透明屋根瓦は、同様に設計自由度が高く、耐衝撃性に優れ、透明度が高いことから、瓦屋根に天窓を設置することが可能である。また発電式ソーラーパネルをインサート成型することもできる。
【0033】
PET樹脂製ヘルメットは、設計自由度が高く、耐衝撃性に優れ、透明度が高く、安全な視野角をとりやすい。
【0034】
【発明の実施の形態】
図1は、本発明の1実施例であり、請求項2に係る滅菌済医療器具(胸骨縫合用ワイヤーシステム)の包装容器である。射出成型により加工されたPET樹脂製容器2の本体部分には胸骨貫通用キリ1a、1bが収納されている。キリ1a、1bの周囲を取り囲むようにワイヤー3が収納されている。ヒンジ4部分は最薄部分が0.3mm厚の平板であり、本体と蓋はヒンジ4を介して一体成型され、スムーズに開閉する。本体と蓋は180度開いた状態で成型される。本体と蓋を閉じると、ヒンジ部分は厚さ0.15mm程破損し、残りの0.15mm厚が適度なバネ性を確保している。ヒンジの厚さを0.2mm以下に設定すると一回の開閉で割れるが、0.3mm確保すると、180度展開で数百回の開閉に耐える。キリ使用後、感染性医療廃棄物として元の位置に収納し、ロック5を掛け密閉する。透明度が高いので、使用した危険物を廃棄する作業が容易に行える。密閉度が高く、衝撃にも強いので、血液漏れや感染の危惧はない。請求項6及び7で提案しているように器具を収納する本体部分の上部にタイベックシートをヒートシールすることにより容器内を密封する。その上から蓋を閉じることにより、機密性、無菌性を高めることが可能である。滅菌方法は機密性が確保されていることからエチレンオキサイドガス滅菌より放射線(ガンマー線)滅菌が適している。PET樹脂は放射線耐性であり、長期に亘って劣化、変色がほとんど発生しない。容器の外側全体を更にタイベック袋で密封すれば更に機密性、無菌性、安全性は確保される。
【0035】
図2は請求項3及び4に係る理化学試験に用いるキャップ付き試験管を示している。PET樹脂を射出成型し、本体6はヒンジ8を介し、蓋7と一体成型されている。ヒンジ8は最薄部分が0.3mmの線状であり、この稜線からテーパー状に両側に厚さを増している。本体6は透明度が高く、中の検体が視認しやすい。落としても割れない。PET樹脂は耐薬品性にも優れているので、あらゆる検体に適応する。簡便に確実に蓋を閉じることができ、密閉度も高い。一体成型なので、安価で量産が可能である。滅菌包装体で外側を密封し、ガンマー線滅菌済とすることも可能である。
【0036】
図3は請求項5及び6に係るスライドグラスを例示している。PET樹脂を射出成型し、本体9はヒンジ11を介し、蓋10と一体成型されている。ヒンジ最薄部分は0.3mm厚の平板を円柱状に丸めた形状となっている。ガラスと異なり、エッジは滑らかで安全である。落としても割れない。透明度が高く、中の検体が視認しやすい。本体中央の窪み12は検体を安定した状態で設置するためのものである。ロック13により簡便に確実に密閉保存が可能である。滅菌済みのものは検体に菌が繁殖しない。一体成型なので、安価で量産が可能である。
【0037】
図4は請求項7に係る眼鏡を示している。PET樹脂を射出成型し、レンズ14a、14b及びレンズ枠15はヒンジ17a、17bを介し、サイドフレーム16a、16bと一体成型されている。ヒンジ最薄部分は0.3mm厚の平板を円柱状に丸めた形状となっている。衝撃に強いので、落としても破損しにくい。レンズ14a、14bはガラス並みに透明度が高い。老眼等、ある程度画一化した視力障害の補正に適している。安価に量産が可能である。
【0038】
その他のPET樹脂を射出成型したヒンジ付き製品としては、医療関係では手術器具ケース、薬箱、ピルケース、その他分野では電気部品、器具、工具のケース、キャリングケース、ブリーフケース、CD、DVD等のディスクケース等が挙げられる。
【0039】
【発明の効果】
以上説明したように本発明により、耐衝撃性に優れ、弾性に富み、透明度が高く、安価で量産品に適したヒンジ付きPET樹脂製品を提供することが可能となる。使い捨て医療器具の収納ケースにした場合、透明度が高いので、使用した危険物を廃棄する確認が容易に行える。密閉度が高く、衝撃にも強いので、血液漏れや感染の危惧はない。容器内側に滅菌用のシートをヒートシールすれば、機密性、無菌性が確保され、外側をタイベック等の袋で密封すれば、更に無菌安定性が増大するばかりでなく、袋が二重にならないので、外装がコンパクトになり、トータルの医療廃棄物体積も減少する。
【0040】
理化学試験で用いる試験管、メスシリンダー、液量計、ビーカー、シャーレ、コップ、採血管、ディスポセル、試薬ビン、沈殿管、遠心チューブ等の器具類は本体に内容物を入れた後、一体成型された蓋を密閉し、試験検査或いは保管が可能である。PET樹脂は耐薬品性にも優れているので、あらゆる検体に適応する。別売りの栓を購入する必要がないので、試験検査コストを削減する。透明度に優れているので、内容物の視認性が高い。PET樹脂は放射線耐性なので、放射線滅菌済みとし、無菌試験等に即使用することも可能である。ガラスに比べて耐衝撃性に優れているので破損の心配は少ない。
【0041】
検体標本を顕微鏡観察、保管するスライドグラスを、PET樹脂で射出成型した場合、長方形板表面に検体を載せる円形の窪みを容易に成型できる。ヒンジを介して一体成型されている蓋を密閉し使用することも可能である。赤血球を載せた場合等、細胞破壊がなく、自然の状態で観察できる。透明度も高く、視認性に優れている。滅菌済みの形態とすれば、指先からの採血の場合等、無菌状態のスライドグラス表面に指を押し当てるので、患者の感染等の心配もなく、開封まで製品自体の雑菌付着もない。落としても容易には割れず、エッジで怪我をすることもない。一体成型なので、安価で量産が可能である。
【0042】
眼鏡をPET樹脂により一体成型した場合、安価で量産が可能となる。老眼鏡等はレンズ規格が少ないので量産向きである。落としても割れず、変形もしにくい。ガラス並みに透明度が高いので、視認性は良好である。金属に比べて軽量で、熱伝導率が低いので、装着したときの皮膚接触温度に変化が少ない。
【0043】
PET樹脂製窓ガラスは、射出成型の特性を生かし、波型や垂直のつき合せ等の変形窓、或いは模様付き、浮き出し文字付きの装飾等の特殊形状を有することを可能とする。また窓枠や取っ手及び施錠部品を窓ガラスと共に一体成型すれば、部品代、工賃共に安価である。またガラスと異なり、ハンマー等で容易に割れないため、防犯上適している。地震や災害の際、ガラスの破片で怪我をする心配もない。熱伝導率が低いので、夏場の暑さを凌ぎ、冬は結露しにくい。透明度が高いので、眺望を妨げることはない。
【0044】
PET樹脂製照明器具カバー、食器は、設計自由度が高く、耐衝撃性に優れ、透明度が高く、熱変形せず、安価に量産できる。ガラスや金属に比べて軽量で、熱伝導率が低いので、夏場照明器具カバーは照明器具の熱を伝えにくい。食器の場合、熱いものは冷めにくく、持ちやすい。冷たいものは温くなりにくく、周囲が結露しにくい。
【0045】
PET樹脂製透明屋根瓦は、設計自由度が高く、耐衝撃性に優れ、透明度が高いことから、瓦屋根に天窓を設置することが可能である。夏場の断熱高価も高い。また発電式ソーラーパネルをインサート成型することもできる。透明度が高いので効率よく太陽熱をソーラーパネルに吸収する。耐衝撃性にすぐれているので、割れる心配は少ない。
【0046】
PET樹脂製ヘルメットは、設計自由度が高く、耐衝撃性に優れ、透明度が高く、安全な視野角をとりやすい。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a processed product formed by using a PET resin.
[0002]
[Prior art]
Conventionally, PC (polycarbonate), PP (polypropylene), PE (polyethylene), and PS (polystyrene) are typical materials for a transparent resin, and PET (polyethylene terephthalate) which is a polyester resin has poor fluidity (moldability). Unsuitable for injection molding. Therefore, while having excellent performances such as transparency and impact resistance, the processing method such as vacuum molding and blow molding has been spread only in the field of flat plate processing such as blister packs and PET bottles. Injection molding of PET is possible to some extent by controlling the temperature of the gate and the mold (for example, see Patent Document 1). In addition, some measures have been taken to ensure transparency and heat resistance (for example, see Patent Documents 2, 3, 4, and 5).
[0003]
In recent years, proposals have been made for PET resins having fluidity, impact resistance, transparency, and heat resistance. (For example, Patent Documents 6 and 7)

JP-A-2003-64167 (P2003-64167A)
[0005]
There is no proposal of a product in which a hinge is provided by integrally molding PET resin.
[0006]
Most of the medical device containers are made of PP, PS, and PE. PS is easily broken, and PP and PE lack transparency. Generally, sterilized products are packaged in an outer bag only, or the outer bag is doubled.
[0007]
Most of the containers formed by molding a transparent resin are made of PC, PP, PS, and PE, and disposable physics and chemistry test instruments are often made of these resins, and are often separate parts with a lid.
[0008]
The slide glass is not made of resin, but is made of glass in terms of transparency and price. There are no sterilized glass slides.
[0009]
Lenses, lens frames, and side frames are made of resin, and there is no integrally molded eyeglasses.
[0010]
The vertical butted glass must be hermetically sealed by caulking the center with silicon or the like. Expensive processing is required to apply a deformation such as a wave shape, a pattern, and a character to the glass.
[0011]
When the lighting fixture cover and tableware are made of resin, most are disposable types made of PS or PP.
[0012]
PET resin has never been used for resin roof tiles, and there is no transparent roof tile.
[0013]
PET resin has never been used for resin helmets, and there is no transparent helmet.
[0014]
[Problems to be solved by the invention]
PC is expensive in material and is not suitable for cheap mass-produced products. Although the hardness is ensured, it is easy to crack when it is formed in a thin plate shape such as a hinge.
