Light-tight carton for x-ray and other light sensitive film

Abstract

This relates to a flip top box type carton wherein there is a top portion which is rupturable relative to the remainder of the carton so as to permit the top end of the carton to open. The carton, however, is so constructed wherein when reclosed, it is light-tight. The carton is particularly adapted to have received therein an inner carton in which a film package is placed. The carton is of a construction wherein it may be erected in situ around the inner carton containing the film pack. The sides of the carton are so constructed at the lines of rupture therealong wherein inner side panels have projecting portions which both facilitate the reclosing of the carton without hang up of the top portion and also to make the corners light-tight. Although conventional locking tabs and locking apertures are provided, the front panel of the outer carton is white while other portions of the outer carton are darkly colored so that when the carton is fully open a top part of the front panel is readily visible in a darkroom and when the top portion is returned to its carton closing position and is locked in place, there are two separate white panels which indicate proper engagement of the locking tabs in their respective apertures.
