A container system for medical instruments comprising a molded plastic reticulated tray composed of a continuous rib that forms a tray rim and a plurality of intersecting ribs defining large openings therebetween. The intersecting ribs are dished and have opposite ends connected to the continuous ribs at spaced apart locations therealong. The plurality of intersecting ribs also have rounded surfaces so that a washing or cleaning fluid directed at the plurality of intersecting ribs from the outside, upon flowing through said openings will follow and intimately contact those rounded surfaces so that those surfaces are cleaned thoroughly. A preferred embodiment of the system also includes a reticulated cover releasably connected to the tray and various brackets for fixating instruments in the tray.

1. A container system for medical instruments, the system comprising: a molded plastic reticulated tray having; a tray rim, formed from a continuous rib, wherein the molded plastic reticulated tray rim forms a perimeter of the molded plastic reticulated tray;a tray wall, formed from a plurality of ribs connected to the tray rim, the plurality of ribs having opposite ends connected to the tray rim at spaced apart locations therealong; anda middle portion of the plurality of ribs forming a tray base, the tray base having a plurality of perpendicularly intersecting ribs formed from the plurality of ribs, the intersecting ribs having a circular cross-section and central axes configured in a plane, said intersecting ribs being dished and defining relatively large openings therebetween whereby a fluid sterilant directed at the plurality of perpendicularly intersecting ribs from the outside, upon flowing through said openings, will follow and contact rounded surfaces to the tray interior so that those surfaces are cleaned. 2. The container system of claim 1, wherein the total area of said openings is at least twice the total longitudinal-sectional area of said plurality of intersecting ribs. 3. The container system of claim 1, wherein the molded plastic reticulated tray is molded of polyphenylsulphone. 4. The container system of claim 1, wherein the molded plastic reticulated tray is generally rectangular and said openings are square. 5. The container system of claim 1, wherein the molded plastic reticulated tray includes at least two similar latch fixtures affixed to the continuous rib opposite and facing away from one another, each latch fixture including a journal bearing and a keeper surface. 6. The container system of claim 5, further including a latch member hinged to each latch fixture at the journal bearing thereof. 7. The container system of claim 1, and further including a reticulated cover which is a mate to said molded plastic reticulated tray so that when the reticulated cover is inverted and positioned with its continuous rim in register with the continuous rim of the molded plastic reticulated tray, the molded plastic reticulated tray and the reticulated cover make line contact and form a cage. 8. The container system of claim 7, further comprising a clamping mechanism for releasably clamping together the continuous rims of the molded plastic reticulated tray and the reticulated cover. 9. The container system of claim 8, wherein the clamping mechanism comprises a plurality of similar first latch fixtures affixed to the continuous rib of the molded plastic reticulated tray, said first latch fixtures being opposite and facing away from one another, a plurality of second latch fixtures affixed to the continuous rib of the reticulated cover, said second latch fixtures being opposite and facing away from one another, each of said latch fixtures including a journal bearing and a keeper surface, said first and second latch fixtures being located directly opposite one another when the continuous ribs of the molded plastic reticulated tray and the reticulated cover are in register with one another, said opposite latch fixtures constituting a cooperating pair of latch fixtures, and a latch member hinged to one of each cooperating pair of latch fixtures at the journal bearing thereof, each said latch member being adapted to engage the keeper surface of the other latch fixture of each cooperating pair of latch fixtures. 10. The container system of claim 1, further comprising at least one instrument holder, having at least one resilient leg, the at least one instrument holder releasably connected to different ones of said plurality of perpendicularly intersecting ribs and spanning at least one of said openings, wherein the at least one resilient leg is disposed substantially perpendicular to the plane of said intersecting ribs. 11. The container system of claim 10, wherein the at least one instrument holder includes a pair of spaced-apart flexible, resilient legs having free ends terminated by mirror image clips, each clip being adapted to engage around different ones of said plurality of intersecting ribs when said legs are flexed. 12. The container system of claim 11, wherein the length of each clip is slightly less than the side length of each of said openings. 13. The container system of claim 12, wherein said at least one instrument holder also includes a plurality of spaced-apart depending posts which are adapted to straddle one of said plurality of perpendicularly intersecting ribs when the at least one instrument holder is releasably connected to said different ones of said plurality of perpendicularly intersecting ribs.
