Description
−活性薬剤の支持体をディフューザの内側の正しい安定位置に保持する。
−活性薬剤と手または使用者の身体の他の部分との接触を防ぐ。
−外側バリア層が取り外されると、周辺環境に向けた活性薬剤の放出を可能にする。
既に述べたとおり、ディフューザが使用者によって最初に使用される前に活性薬剤の拡散が始まるのを防ぐため、流体に不透過性のバリアフィルムが、格子の外側上に適用される。格子材料とバリアフィルムとは、接着剤または熱溶接によって、安定して接着する。これら2つの要素間の接着強度は、活性薬剤が格子とバリアフィルムとの間で漏れること、またはバリアフィルムが輸送、保管、および販売中に偶発的に剥がれることを防ぐように十分高く、しかし、使用者が過剰な労力なしに使用時にバリアフィルムを取り外せるように十分低くなければならない。
−前述したとおり、格子は通常、射出成形プラスチック材料で作られるが、バリアフィルムを適用する前に、容器に加えて別個の要素を製造するため、それ自体の製造コストと、それをディフューザ本体に対して組み立てるための追加コストとがかかる。
−格子へのバリアフィルムの適用プロセスは、ある複雑さ(ラベルの位置付け、射出成形部品の非平面性、部品間の位置付けの差など)を有し、それによって、製造品の最終品質に欠陥が生じる可能性がある。
−活性物質は、その適用中に接着層と相互作用するか、または、熱溶接プロセスを妨げて、格子からのバリアフィルムの早期分離を引き起こし得る。
−製造される部品の数を減らし、その結果、組立工程を単純化することによって、既知のタイプのディフューザの製造プロセスにおける前述した欠点を克服し、
−バリアフィルムの接着安定性に関して、その結果として、起こり得る活性薬剤の漏れに関して、よりよい性能を提供し、
−ディフューザの起動機能のより容易な始動動作を使用者に対して許容し、最後に、
−既知の技術のディフューザと比べて製造コストの減少を示す、
ディフューザのための構造体を提供することである。
−内側シール層2であって、前記層の厚さ全体にわたり、所定のパターンに従って延びる切り込みの内側構造を有する、活性薬剤の固体またはゲル状の支持体を安定位置に保持しやすい、内側シール層2
−活性薬剤が外向きに漏れるのを防ぎやすい、外側バリア層3a
−中間剥離層3bであって、バリア材料の外側層3aにその突出タブ3’を通じて十分な牽引努力が加えられた場合に前記中間剥離層3bと内側層2との間を剥がすことにより切り離しを促進しやすい、中間剥離層3b
Claims (15)
- 気体または液体状態のいずれかである流体環境の処置のための、活性液体薬剤のディフューザであって、
前記活性薬剤を所定の位置に保持しかつ前記活性薬剤の流体の発散を可能にしやすい格子手段によって閉鎖される、前記活性薬剤の容器(1)を備え、
前記格子手段は、前記格子手段を動作させる最初の使用時に剥がすことができるバリアフィルムによって覆われ、
前記容器(1)は、少なくとも外側バリア層(3a)と、少なくとも別の内側シール層(2)とを含む単一の多層フィルム(3)によって閉鎖され、
前記内側シール層(2)は、1本以上の閉鎖線に従って少なくともその深さ全体にわたって延びる切り込みの内側構造を有し、
前記閉鎖線は、前記内側シール層(2)の残部と横方向に接続されなくなる、取り外し可能な部分(4)の前記周囲の境界を定め、
前記内側シール層(2)は、前記バリアフィルムおよび前記内側シール層(2)の前記部分(4)を同時に取り外した後、前記容器の最初の使用時に、前記活性薬剤を所定の位置に保持しかつ前記格子手段を形成し、
前記多層フィルム(3)は、前記外側バリア層(3a)と前記内側シール層(2)との間に中間剥離層(3b)をさらに備える、
ことを特徴とする、ディフューザ。 - 前記多層フィルム(3)は、
−内側シール層(2)であって、前記層の厚さ全体にわたり、所定のパターンに従って延びる切り込みで内側が構成された、前記活性薬剤の支持体を安定位置に保持しやすい、内側シール層(2)と、
−前記活性薬剤が外向きに漏れるのを防ぎやすい、外側バリア層(3a)と、
−中間剥離層(3b)であって、前記外側バリア層(3a)に十分な牽引努力が加えられた場合に前記中間剥離層(3b)と前記内側シール層(2)との間を剥がすことにより切り離しを促進しやすい、中間剥離層(3b)と、
