Abstract

A container for holding dental or medical implements within the sterilization chamber of a clinical sterilizer includes a bottom tray and a cover element which cooperatively effect a Morton-type closure. The cover element is adapted to permit viewing of the sterilized contents of the container without disturbing the closure. The cover element may be a transparent flexible sheet held against the sidewall of the bottom tray by a clamp, with the sidewall, cover and clamp together effecting the Morton-type closure.

Claims

1. A container for holding articles during sterilization procedures and thereafter in storage comprising:

a rigid bottom tray with a bottom and a continuous sidewall upstanding from the perimeter of said bottom, thereby to define an interior space; and

a cover element with a top member and a clamping structure positioned in association with the perimeter of said top member adapted to couple with said sidewall to effect a Morton-type closure of said interior space, said cover element comprising a transparent flexible sheet material which permits viewing of the interior of said container without disturbing said Morton-type closure.

2. A container according to claim 1 including rack means contained within the interior of said bottom tray, for holding a plurality of dental hand instruments in approximately parallel, side-by-side relationship across substantially the entire cross-sectional area of said bottom tray.

3. A container according to claim 1 wherein said cover element comprises a transparent flexible sheet material having a peripheral portion overlapping said sidewall of said bottom tray.

4. A container according to claim 3 wherein said overlapping sheet material is held in place against said sidewall by clamp means.

5. A container according to claim 3 wherein said Morton-type closure is effected by an opening through said sidewall and by structural means associated with said opening to hold said cover element out of contact with said opening so that when the container is placed within a chemical sterilizer under sterilizing conditions, sterilizing vapors are permitted to enter into the interior of said bottom tray, thereby to displace the initial atmosphere from said tray.

6. A container according to claim 5 wherein said sidewall of said bottom tray is rectilinear in configuration as viewed from the bottom, and includes two opposed ends, each of which extends from connection between two opposed sides;

and a said opening is provided in each said end.

7. A container according to claim 6 wherein each said opening is postiioned adjacent the top member of said cover element when said cover element is positioned atop said bottom tray.

8. A container for holding articles during sterilization procedures and thereafter in storage conditions, said container comprising:

a rigid bottom tray having a bottom and a continuous side wall including two opposed ends, each of which extends from connection between two opposed sides, thereby to said bottom tray defining an interior space, said sidewall having an upper edge, each of said ends of said sidewall of said bottom tray being provided with a pari of outwardly extending exterior bosses, said bosses being mounted on an exterior surface of each of said sidewall ends, each said boss having a proximal end and a distal end, each said sidewall defining two slots, each said slot extending from said sidewall upper edge downward toward said bottom, each said slot being positioned between a respective pair of said bosses;

two exterior ridges, one said ridge being mounted on each of said opposing sides of said bottom tray, each said ridge being oriented approximately parallel said bottom;

a transparent, flexible sheet positioned over said sidewall'"'"'s upper edge, said sheet having a peripheral portion overlapping said sidewall of said bottom tray;

a rigid band positioned over said peripheral portion of said flexible sheet and below said exterior ridges, said ridges retaining said band in a manually detachable locked position over said bosses, said band being positioned between said proximal end and said distal end of each said boss, said band retaining said flexible sheet in a press-fit engagement against said bosses, said bosses constituting structural means for holding said sheet out of contact with said slots, and each said slot being positioned between a pair of said bosses, said sheet defining a cover over said slots and on open pathway between said sheet and said sidewall, said pathway communicating each of said slots with the environment.

9. A container according to claim 8 wherein said sidewall of said bottom tray carries exterior ridges extending approximately parallel the bottom said bottom tray, said ridges being intercooperable with said clamp means.

10. A container according to claim 9 wherein said clamp means comprises a substantially rigid band configurated to slide over said peripheral portion of said transparent sheet material, thereby to hold said peripheral portion in press-fit engagement with said bosses on said ends of said sidewall and in locking engagement with said exterior ridges.

11. A container for holding articles during sterilization procedures and thereafter in storage comprising:

12. a rigid bottom tray with a rectilinear bottom and a continuous rectilinear sidewall upstanding from a perimeter of said bottom, said sidewall including two opposed ends, each of which extends from connection between two opposed sides, said bottom tray defining an interior space, said sidewall having an upper edge, each of said sidewall ends defining a slot therein which extends from said sidewall upper edge downward toward said bottom, each said sidewall end being provided with a pair of outwardly extending bosses mounted spacedly apart from one another, each said slot being positioned between a respective pair of bosses, each boss having a proximal end and a distal end;

a transparent flexible sheet positioned over said upper edge of said sidewall, said sheet having a peripheral portion overlapping said sidewall of said bottom tray, said sheet coupling with said sidewall to effect a Morton-type closure, wherein said Morton-type closure is effected by each said slot through said sidewall and by each pair of said exterior bosses mounted on said sidewall and associated with a respective said slot to hold said sheet out of contact with said slot so that when the container is placed within a chemical sterilizer under sterilizing conditions, sterilizing vapors under dynamic flow conditions are permitted to enter into the interior of said bottom tray, through an open passageway define between said sheet and said siedwall, thereby to displace the initial atmosphere from said tray;

a pair of exterior ridges mounted on said sidewall sides, each said ridge being oriented approximately parallel said bottom, said flexible sheet having a peripheral portion overlapping said slots and said exterior ridges of said bottom tray;

a clamping structure for retaining said sheet in a manually detachable press-fit relationship against said exterior bosses and out of contact with said slots, said clamping structure having a substantially rigid band positioned over said peripheral portion of said flexible sheet and below said exterior ridges, said ridges retaining said band in a manually detachable locked position over said bosses, said band being positioned over said bosses between said proximal end and said distal end of each said boss, said band being configurated to slide over a peripheral portion of said transparent sheet positioned over said exterior bosses and below said exterior ridges, said flexible sheet providing a transparent window which permit viewing of the interior of said container without disturbing said Morton-type closure;

wherein said slots and said pathway provide a suitable access into and out of said interior space to permit a displacement of an initial atmosphere within said interior space by a desired atmosphere provided to a vicinity of said pathway under dynamic flow conditions; and

wherein said flexible sheet provides a sufficient protection for said slots to contain said desired atmosphere within said interior space and further functions as a barrier against penetration by an undesirable ambient atmosphere through said slots under static storage conditions.
