a.金属酸化物及び有機材料で被覆されたTiO2粒子と、1つ以上の溶融加工可能な樹脂と、を含む単層であって、25〜120のLPF値を有し、TiO2粒子の濃度が、単層の6〜14wt%である、単層と、
b.任意に、1つ以上の美観層と、を備え、単層が、2リットル〜8リットル(0.5ガロン〜2ガロン)の範囲の流体体積を保持するように形作られている、パッケージ設計を含む。
吹込み成形は、空気圧を使用して軟質プラスチックを成形型キャビティ内へと膨張させる成形プロセスである。吹込み成形技術は、当技術分野において、例えば「Petrothene(登録商標)Polyolefins...a processing guide」、第5版、1986年、U.S.I Chemicalsで、開示されている。吹込み成形は、ボトル及び類似の容器などの薄肉な一体型の中空プラスチック部品を作製するための重要な工業プロセスである。吹込み成形は、(1)パリソンと呼ばれる溶融プラスチックの出発チューブの製作と、(2)所望の最終形状へのチューブの膨張と、の2段階で達成される。パリソンの形成は、押出成形又は射出成形の2つのプロセスのいずれかにより達成される。
1つ以上の感光性実体の変化の速度は、「光保護係数」又は「LPF」と呼ばれ、不透過性及び/又は光透過率の測定値とは異なる。LPFは、感光性実体濃度の半分が変換するのに必要な時間である。それゆえに、高LPF値のパッケージにより保護された1つ以上の感光性実体を含む材料は、低LPF値のパッケージにより保護された同じ材料と比較して、感光性実体に変化が生じるまでにより多くの光に暴露され得る。LPFの測定についての詳細な説明は、参照により本明細書に組み込まれる「Methods for Determining Photo Protective Materials」と題された国際公開第2013/163421号及び「Devices for Determining Photo Protective Materials」と題された国際公開第2013/162947号に更に記載されている。更なる情報は、本特許出願の実施例の項に見出すことができる。
押出吹込み成形プロセスを使用したボトルの生産のために、Uniloy 250 R1機械を使用した。以下に記載の工具を用いて、HDPE剛性パッケージングを加工するための標準的な慣行及び設定を使用した。
ダイ:メッキされたMA 1002−80
マンドレル:MA 1002−9
成形型:容器MA−8552
−フィード部:163℃(325°F)
−輸送部:182℃(360°F)
−添加剤計量部171℃(340°F)
−ダイブロック:171℃(340°F)
実施例1に記載のボトル条件1及び2の代表的なボトルを、落下試験により、機械的性能について更に評価した。落下試験は、吹込み成形ボトルの機械的な無欠陥性を判定するための合否試験であり、液体を充填したボトルを既定の高さから落下させること、及び吹込み成形ボトルが液体容器としての無欠陥性を喪失することなく落下の衝撃に耐えるかどうか観察することを含む。落下試験を61センチメートル(24インチ)の高さから行った。落下高さは、ボトルの基部から定義される。落下試験を屋外で(〜10C)、乾燥した平坦なコンクリート面上で行った。ボトルをまっすぐに、落下試験にわたって一貫した様式で案内するために、スリーブを使用した。ボトルをスリーブ内に配置し、下から手で支持した後、支持する手を放して、ボトルを落下させた。
