Abstract
An apparatus for inspecting a pharmaceutical cylindrical container made of a polymer, a specific method for inspecting a pharmaceutical cylindrical container made of a polymer and a specific bundle of pharmaceutical cylindrical containers made of a polymer.
Claims20
An apparatus for inspecting a pharmaceutical cylindrical container made of a polymer and detecting slides in the polymer, comprising:
- a support device configured to support the pharmaceutical cylindrical container and rotate the cylindrical pharmaceutical container around a longitudinal axis;
- a light emitting unit comprising a light source configured to illuminate the pharmaceutical cylindrical container with an inspection beam having a wavelength from 100 nm to 400 nm to stimulate photoluminescence of the of the pharmaceutical cylindrical container;
- and
- a light receiving unit that is configured to detect slides in the polymer, the light receiving unit comprising a filter that blocks light having a wavelength of 600 nm or more and a camera that receives light emitted by the pharmaceutical cylindrical container due to the photoluminescence and acquires an image of the pharmaceutical cylindrical container,
- wherein the polymer is a cycloolefin copolymer (COC) or a cycloolefin polymer (COP).

A method for inspecting a pharmaceutical cylindrical container made of a cycloolefin copolymer (COC) or a cycloolefin polymer (COP), comprising:
- illuminating the pharmaceutical cylindrical container with a first light emitting unit;
- receiving light emitted by the pharmaceutical cylindrical container with a light receiving unit to acquire a first image of the pharmaceutical cylindrical container;
- receiving light scattered by and/or transmitted through the pharmaceutical cylindrical container with the first light receiving unit or a second light receiving unit to acquire a second image of the pharmaceutical cylindrical container;
- and
- characterizing defects in and/or on the pharmaceutical cylindrical container based on a comparison of the first image showing emitted light and the second image showing scattered and/or transmitted light
- analyzing the defects to identify slides in the COC or COP of the pharmaceutical cylindrical container.
