DETAILED DESCRIPTION OF THE FIGURES

[0028] FIG. 1 shows an embodiment of the invention, featuring the fold up stamped manufacture of the base/tray. The cassette fits inside most autoclaves, including Midmark and Ritter autoclaves, Tuttnauer and Scican Statim and Hydrim autoclave machines, sterilizers, and more. The invention also fits inside standard baskets for ultrasonic cleaners. The preferred cassettes are the 5 instrument embodiment at 721.5 (last dimension=height/depth). Another embodiment is for the medium 8 instrument cassette at 741.5 (last dimension=height/depth). Other embodiments come in 84.52, 732, and other dimension cassettes are available.

[0029] Reference number 102 is the tray, 104 is the (optional but preferred) grooved rail to engage the notch-ridge along the inside of the lid-cover (not herein shown); 106 drainage apertures throughout, prevent pooling (preferred embodiment hex hole shape has numerous benefits, especially, herein, they hold the pliable (usually silicon) clamping strips 204 [also called posts 402, depending on shape of dental instrument held and length and positioning of strip], to prevent the strips/posts 204 from rotating in place (which would allow the dental instruments to jostle, come loose during sterilization, and accidentally poke dental workers). The (optional but preferred) hex holes 106 therefore aid drainage, and also provide proper anchors for the strip 204 plugs 502 to securely (removably) fasten in place. This hex style prevents accidental disengagement or rotation (which would create a mess-o-dental-instruments inside the cassette, post-sterilization).

[0030] The [preferred] silicone gripper and rail system reduces instrument contact, allowing for cleaning solutions to agitate-away more debris. [One embodiment] Stainless steel housing construction in the tray/base protects against corrosion. Apertured-edges allow for superior drainage and drying. The [preferred] hexagonally shaped apertures offers multiple advantages, discussed infra and supra.

[0031] FIG. 2 shows base 202, which may alternatively (not herein shown) be convex (middle up) to prevent pooling, the pliable gripping strip 204, herein taking the form of a securing strip affixed (plugged) to the top via aperture plugs (helps to secure the instruments below during the bumpy-and-steamy autoclave-&-sterilization processes), the lid's notch-ridge 208, while optional, helps secure the lid, the apertures 106 are shown throughout the lid. The lid 210 should, if [preferred] silicon-pliable material, securely fit over tray 102 ridged rails 104 to hold the unit together for autoclave, sterilization, and storage.

[0032] FIG. 3 features the anti-slip feet 302/304, being the same size in the embodiment shown in FIG. 3, but often differently-sized to create base 202 canting in other embodiments (infra). Feet 302 plug through hex apertures 106 as other gripper plugs, and are preferably rubber or silicon or appropriate similar compound thereof (ideally the same material as all the other the strips 204 and posts 402) (Reference numbers 204 and 402 used interchangeably as/where appropriate, as the interchangeability of plug-strip-posts 204/402 (and their alternate sizing) is a key component of the instant invention). All 204/402 strip/posts feature the same plug style removable fasteners 502 and (when posts to grab and secure instruments) the shovel-and-groove style clamp tops 404.

[0033] FIG. 4 herein shows differently sized anti-slip feet 302 and 304, respectively, preferred canting not herein shown, the shovel and groove shaped clamp-top 404 to the gripping strip/post 402, the clamped dental instrument 406 (herein a pointy probe, showing the need for stable clamps).

[0034] FIG. 5 shows the cassette assembled (lid-on) for sterilization and storage, herein showing the gripping strip 502 plugged through the hex holes 106.

[0035] FIG. 6 shows the main tray with gripping strips/posts 402 plugged/secured through the hex base holes 106, herein two strips positioned in parallel to hold elongated dental instruments. As with all the invention's pliable strips/posts 402, different dental instruments may receive different strip/post 402 sizes and configurations, therein making the dentist's presentation/diagnostic stage, and latter-sterilization/hygiene processes, easier and tailor-made for the instruments s/he is using. Said strips/posts 402 may also be color-coordinated by instrument-type or by patient, or other logical indexing means.

[0036] FIG. 7 shows multiple probes 406 and a mirror 406 (all dental instruments 406 for reference purposes) securely held by gripping posts/strips 402/204 (here said strips are arranged in parallel). Note the tray is sufficiently deep to hold canted-mirrors 406, which the gripper posts 402 accommodate due to their pop-in/pop-out versatility (allowing various posts 402 to be different heights when needed, such as for odd-shaped instruments like mirrors [unlike probes, which are fairly common in size and shape]).

PREFERRED EMBODIMENT OF THE INSTANT INVENTION

[0037] Cassette feet are silicone-rubber [either or compound or mixture] stoppers 302/304 feet for support, improving drainage and preventing slippage. Small and large feet are optionally positioned on the distal and proximal ends, effectively creating a drainage chute [canting of base 202], as base is then a canted cassette floor for superior drainage. Adjustable color coded Snap-in/Plug-in support retainers (Grippers) 204/402 to anchor and secure [usually] and thinner probes 406; also for bigger mirrors 406; adjustable walls within the cassette (formed by popping-in-additional-strips 204, not herein shown), also anchored with the hex plugs.

[0038] Hexagonal drainage apertures 106 allow proper spillage, prevents pooling and allows instrument debris to flow out of the cassette. Other hole shapes are appropriate for the invention, so long as their width and geometry allows for the secure pop-in-pop-out method of securing rails/grippers 204/402. The size, arrangement and shape of [preferred hex] holes (drainage apertures) 106 prevents instruments from sticking/poking out of the cassette and therefore from poking the dental hygienists and other workers.

[0039] Stainless steel [preferred] housing 102 with silicone (or similar semi-pliable) (antibiotic-treated) lid 210; adjustable (including diagonal [alternative embodiment, but easily adjustable by dentist upon arrival]) gripping rail 204/402 design, adjustable for odd shaped instruments 406.

[0040] [Preferred] Silicone lid cover 210 (rather than steel or metal) (BPA Free), with Triclosan-style (e.g. Microban) antibiotic added to the lid material (rather than mere stainless steel). The lid 210 pops on and off like Tupperware (or similar groove lip and ridge system). The lid also optionally has at least one corner tab for easy-opening (grabbing) (not herein shown).

[0041] Lid 210 and Cassette Tray/Base 202 may also have convex planes, to further improve drainage and prevent pooling;

[0042] Hygiene Size and Diagnostic Sizes available (5-instrument and 8-instrument cassette sizes as preferred embodiments).

[0043] Hexagonally shaped apertures 106 further stabilize the individual-instrument grippers (preventing twisting);

[0044] Cassette lid 210 has plurality of hex-shaped apertures 106 to allow individual (non-paired) grippers 402 to house and anchor individual odd shaped dental instruments 406 like pliers or syringes.

[0045] Cassette 102 can be loaded into an autoclave or ultrasonic machine either face up or face down while securely anchoring the dental instruments.

[0046] Shovel plug and groove shaped clamp topped 404 adjustable silicone grippers 404 (arranged as colored gripping sets) safely grip almost any dental instrument.

[0047] Unique color coordination of shaded-borders on hex tray and lid holes 106 (including optional color-coated anodized [optional] stainless steel [optional] itself on lid and tray) for easy insertion of same-colored gripping strips 402/204 to house elongated (and individual) instruments 406 (majority of border shading for standard perpendicular).

[0048] Traversing double-rail grippers 204, but diagonal and individual color coating for odd-shaped instruments is a [preferred] novel feature of the instant invention.

[0049] Optional Grass-like (bristly) Silicone [preferred] Clamping-Sheet Insert (not herein shown) provides additional stability and anchoring for instruments, while allowing the instant invention to maintain its shovel and groove topped 404 gripping strips 402 to still function without impedance. The sheet acts as ballast, and as support, to further buttress the instruments against their rail 402 clamps 404, to prevent jostling.
