Abstract: A lockable molded box enclosure is configured to contain and store several types and quantities of instruments commonly used for dental hygiene home use, such as toothbrushes and dental floss. The box includes a lid or door and a latch that must be operated in order to gain access to the instruments contained therein, and the latch is constructed to be operated by inserting an instrument related to the steps involved in dental hygiene. The preferred embodiment discloses a box with a hinged lid and a latch operable by inserting a length of dental floss tautly held and downwardly pressed into a slot formed by the edge of the lid and the edge of the box opening, such that the length of floss will depress a spring-biased locking tab.
