Abstract
A cassette for dental instruments includes a tray having bottom and a plurality of walls extending to a particular plane, the walls defining first and second generally opposing slots. A lid having a generally planar configuration is adapted to mount on the tray with its outer surface disposed in the particular plane. A fixed tab on the lid is adapted to register with the first slot, while a moveable tab on the lid is slidable between a retracted position and an extended position wherein the moveable tab registers with the second slot.
Claims20
A cassette for dental instruments comprising:
- a tray having a bottom and a plurality of walls each extending from the bottom to a particular plane;
- means extending between the walls of the tray for individually supporting dental instruments;
- portions of the walls defining first and second generally opposing slots;
- a lid having a generally planar configuration and an outer surface, the lid being constructed to mount on the tray with the outer surface disposed in the particular plane of the tray;
- a first tab disposed in fixed relationship with the lid and adapted to register with one of the slots in the tray;
- and
- a second tab carried by the lid and movable between an extended position and a retracted position, the second tab in the extended position being disposed to register with the second slot to lock the lid to the tray.
A cassette for storing dental instruments comprising:
- a tray being constructed to receive dental instruments, the tray having a bottom wall and a pair of generally opposed end walls each extending from the bottom to a particular plane;
- portions of the generally opposed end walls defining first and second generally opposed slots;
- a lid having first and second major surfaces and being constructed to mount on the tray with the first major surface disposed generally in the particular plane of the tray;
- a first tab disposed in fixed relationship with the lid and adapted to register with the first slot in the tray;
- and
- a second tab carried by the lid and slidable along the second major surface of the lid between an extended position and a retracted position, the second tab in the extended position being disposed to register with the second slot to lock the lid to the tray.
The cassette for dental instruments comprising:
- a tray having a bottom wall, a peripheral wall extending from the bottom wall and an open top;
- means in the tray for supporting dental instruments;
- portions of the peripheral wall having first and second apertures opening into the tray;
- a lid being constructed to mount on the tray to cover the open top;
- a first tab on the lid and adapted to be received in the first aperture in the peripheral wall;
- a locking mechanism carried by the lid and movable between a locking position in which the locking mechanism is at least partly receivable in the second aperture to lock the lid to the tray and a releasing position in which the locking mechanism is out of the second aperture to allow the lid to be moved to uncover the open top of the tray;
- and
- at least one of said tray and lid having a plurality of openings therein.
