Title (EN) METHOD AND APPARATUS FOR INSPECTING SEALED PACKAGES FOR PINHOLES
(FR) PROCEDE ET APPAREIL DE CONTROLE DE PAQUETS SCELLES POUR DETECTER LES TROUS D"AIGUILLE
Abstract: front page image
(EN)A method and an apparatus for inspecting for pinholes in a sealed and packaged body in vacuum, which body accommodates a volatile substance such as a glucose injection solution, distilled water for injection, milk, oil or the like, and a sublimated substance such as naphthalene or the like. These will be referred to as "volatile substances" hereafter. In accordance with the invention, the judgement as to whether or not pinholes are present is performed accurately by first eliminating any outside influence attributed to a volatile substance either attaching to the outside of the packaged body or remaining within the inspection chamber. This is accomplished by vaporizing the volatile substance in advance using a vaporization evacuation unit provided in the inspecting chamber, the vaporized substance being cooled and retrieved by a cooling heat exchanger.
(FR)Procede et appareil de controle et de detection des trous d"aiguille dans un corps scelle et empaquete sous vide, ce corps contenant une substance volatile telle qu"une solution d"injection au glucose, de l"eau distillee d"injection, du lait, de l"huile ou autre, et une substance sublimee telle que du naphtalene ou autre. Ces substances sont denommees ci-apres "substances volatiles". La detection des trous d"aiguille est realisee avec precision par elimination prealable de toute influence exterieure attribuee a une substance volatile soit rattachee a l"exterieur du corps empaquete soit restant a l"interieur de la chambre de controle. A cet effet, on vaporise la substance volatile en utilisant une unite d"evacuation de vaporisation montee dans la chambre de controle, la substance vaporisee etant refroidie et retablie par un echangeur de chaleur de refroidissement.
