Description
Claims (1)
- 【特許請求の範囲】 1. 変形可能な容器(2)の気密性を検査する方法であって、容器(2)内に 負圧を発生せしめ、前記容器の内圧を測定する方法において、 前記容器内の負圧を前記容器(2)の変形によって発生せしめることを特 徴とする方法。 2. シール帯(6)を前記容器の開口(8)上に載せることによって前記容器 (2)内の負圧を維持することを特徴とする請求項1に記載の方法。 3. 前記負圧のレベルを、前記容器の開口(8)の領域において、前記負圧に よって前記シール帯(6)に形成された凹部(9)から測定することを特徴とす る請求項2に記載の方法。 4. 気密性を有する容器(2)が負圧によって前記シール帯(6)に吸い付け られ、付加的なサポートなしに搬送される一方、欠陥を有する容器(2)は前記 シール帯(6)から落ちるように前記負圧を前記容器(2)内に発生せしめるこ とを特徴とする請求項2に記載の方法。 5. 請求項1〜請求項4のいずれかによる方法を実施するに適した装置であっ て、前記容器(2)に対する搬送手段(1)を備えた装置において、 前記搬送手段(1)上を搬送される前記容器(2)を変形させる圧縮間隙 (5)を有する圧縮装置(ゴム引きローラ3、4)を備えていることを特徴とす る装置。 6. ループ状のシール帯(6)が前記搬送手段(1)上に間隔をあけて配置さ れた少なくとも2本のガイドローラ(7)によって案内されており、第一の前記 ガイドローラ(7)は前記圧縮 間隙(5)の上方に配置されていることを特徴とする請求項5に記載の装置。 7. 前記容器(2)内の負圧を測定するための測定装置は、第二の前記ガイド ローラ(7)の前方に配置されていることを特徴とする請求項6に記載の装置。 8. 前記測定装置(10)は前記シール帯(6)に形成された凹部(9)の深 さを測定する変位測定装置(12)からなっていることを特徴とする請求項7に 記載の装置。 9. 前記シール帯(6)の下側領域において、前記搬送手段(1)は途切れて おり(間隙20)、気密性を有する容器(2)は前記シール帯(6)に吸い付け られて前記間隙(20)を渡って搬送される一方、欠陥を有する容器(2)は前 記間隙(20)の範囲内で前記シール帯(6)から分離され、前記間隙(20) 内に落下することを特徴とする請求項6に記載の装置。
