Abstract
Abstract A container for a dental X-ray film package which can prevent attachment of saliva of a patient to the dental X-ray film package contained therein. The container comprises a containing element formed from a flexible sheet for containing a dental X-ray film package therein, and a gripping element formed from at least one flexible sheet and connected to the containing element. The gripping element extends outwardly of an oral cavity of a patient when the containing element is inserted in the oral cavity. When an X-ray photograph is to be taken, a dental X-ray film package is inserted into the containing element and then the containing element is placed at a suitable position for photographing of a tooth. After X-ray photographing, the gripping element is gripped to take out the containing element from the oral cavity and pulls or tears off the gripping element in the opposite directions to open the containing element to take out the film package from the containing element. The film package thus taken out is free from saliva of the patient.
