    • A light-tight, self-contained canister and light sealing, anti-blooming tab, of generally rectangular shape, for preventing a roll of core wound photosensitive media, containable within the canister and used in a microfiche or microfilm reader-printer, from being damaged or exposed to actinic light during shipping and storage. The canister includes an open-ended, opaque tubular sleeve having an exit slot, and the sleeve is closed at both ends by opaque end caps fastened thereto. The tab includes an insertable portion joined along a fold line to an extendable portion. The insertable portion may be inserted into the exit slot and engageably wedged between the roll of core wound photosensitive media and the sleeve to prevent undesired rotation. In addition, the extendable portion of the tab is folded at the fold line along the exit slot. Further, the extendable portion includes two outer edge flaps which may be folded and inserted between the end cap outer edges and the sleeve to prevent the end portion of the media from being pulled back into the canister where it would become inaccessible. Thus, the tab light seals the exit slot and can be easily removed by grasping and pulling it.
    • 通常为矩形形状的不透光的,独立的罐和光密封防雾片,用于防止卷筒内卷绕的感光介质,容纳在罐内并用于缩微胶卷或微缩胶片读取器 - 打印机中, 在运输和储存期间损坏或暴露于光化灯。 该罐包括具有出口槽的开放式,不透明的管状套管,并且套筒在两端由固定在其上的不透明端盖封闭。 突片包括沿着折叠线连接到可延伸部分的可插入部分。 可插入部分可以插入出口狭槽中并且可接合地楔入卷绕的卷绕感光介质的辊和套筒之间以防止不期望的旋转。 此外,突片的可延伸部分沿着出口狭缝折叠在折叠线处。 此外,可延伸部分包括两个外边缘翼片,其可以折叠并插入在端盖外边缘和套筒之间,以防止介质的端部被拉回到罐中,在那里它将变得不可接近。 因此,片状灯密封出口槽,并且可以通过抓取和拉动来容易地移除。
