Abstract
This packing case comprises a support provided with a plurality of separate parallel cavities adapted to receive the dental canal instruments and a protection cover consisting of a self-adhesive sheet. This sheet of thin transparent and flexible material has a gripping edge parallel to the longitudinal axis of the cavities and this edge projects laterally from the support surface. By raising the sheet by means of the gripping edge the user can uncover the cavities one by one and thus pick up a selected instrument by simply turning the case upside down, the other instrument being retained in the case. With this packing case it is possible to pack various types of dental instruments such as files, reamers, drills, Hedstroem files, nerve broaches, etc., and the cover may also be used as a label carrying inscriptions concerning the type of dental instrument contained in the case.
