Abstract
Abstract An in-room sharps container for hospital rooms and the like provides superior safety, versatility and economy by featuring a tapered, stackable body with a permanently hinged cover which is irreversibly interlockable with the body and which carries a semicylindrical dome covering the major portion of a pivotable semicylindrical dump tray. The dump tray can be permanently locked for disposal of the container by an over-center biased pin which locks the dump tray in the closed position. A stepped notch is provided in the cover above the tray for unscrewing and dumping blood collection needles without touching them. Hollow carrying handles protect personnel from contact with contaminants on the exterior of the container when it is being carried.

Claim 1
Independent Claim
93 words
A disposal container for medical sharps comprising: (a) a puncture-resistant body for receiving discarded sharps; and (b) a cover for covering said body; said cover including: (i) a substantially semicylindrical dome; (ii) a substantially semicylindrical dump tray substantially coaxial with said dome and pivotable about said common axis between an open and a closed position; (iii) said dome being axially substantially coextensive with said dump tray but having an inclined edge forming a receiving opening giving access to the interior of said dump tray when said dump tray is in said open position.
Claim 2
Dependent Claim
93 words
A disposal container for medical sharps comprising: (a) a puncture-resistant body for receiving discarded sharps; and (b) a cover for covering said body; said cover including: (i) a substantially semicylindrical dome; (ii) a substantially semicylindrical dump tray substantially coaxial with said dome and pivotable about said common axis between an open and a closed position; (iii) said dome being axially substantially coextensive with said dump tray but having an inclined edge forming a receiving opening giving access to the interior of said dump tray when said dump tray is in said open position.
Claim 3
Dependent Claim
29 words
The container of claim 1, in which said cover further includes a dumping lever on said dump tray for rotating said dump tray between said open and closed positions.
Claim 4
Dependent Claim
35 words
The container of claim 1, in which the walls of said body and an end wall of each of said dome and dump tray are tapered, and said cover is hingedly attached to said body.
Claim 5
Dependent Claim
73 words
The container of claim 3, in which said cover includes a pair of depending flanges on a side thereof spaced from said hinge, said flanges being disposed so as to receive the upper end of a wall of said body therebetween when said cover is closed, said body wall and one of said flanges having mating interlocking ridge and recess means for non-releasably interlocking said cover and body when said cover is closed.
Claim 6
Dependent Claim
64 words
The container of claim 4, in which the outer of said flanges is of sufficient extent to prevent visual observation of said ridge and recess means when said cover is closed, and the inner of said flanges is sufficiently close to said wall to prevent said ridge and recess means from being pushed out of engagement with one another when said cover is closed.
Claim 7
Dependent Claim
64 words
The container of claim 1, in which said body has a handle formed thereon substantially adjacent the interface between said body and said cover, the portion of said handle which is engaged by the fingers when said container is carried being open downwardly but being closed on both sides and the top to protect said fingers from contact with fluid leakage at said interface.
Claim 8
Dependent Claim
18 words
The container of claim 5, in which said container is symmetrical about a vertical plane through its center.
Claim 9
Dependent Claim
76 words
The container of claim 1, in which said dump tray has an aperture formed therein, said container further comprising: (c) pin means for selectively engaging said aperture to lock said dump tray in the closed position; (d) over-center biasing means for normally holding said pin means in an non-engaged position but maintaining said pin means in the engaged position once said pin means has been pushed toward said dump tray when said dump tray is closed.
Claim 10
Dependent Claim
40 words
The container of claim 8, in which said dump tray includes a dumping lever for actuating said dump tray, and said pin means is positioned on said dome in a location remote from said receiving opening and said dumping lever.
Claim 11
Dependent Claim
59 words
The container of claim 1, in which said cover further includes (iv) a notch formed in said inclined edge above said dump tray; (v) said notch being shaped to engage the shank of a blood collection needle rotatably detachable from a holder, and to retain the same against rotation when said holder is rotated to detach said needle therefrom.
Claim 12
Dependent Claim
32 words
The container of claim 10, in which a side of said notch is stepped to provide successive shank-engaging areas parallel to the opposite side of said notch but at different distances therefrom.
