A sharps container 10, 20 for used syringes is disclosed which can withstand a crushing force in the direction of the longitudinal axis of a syringe 15 without the needle 11 of the syringe penetrating the base 7 of the container. Instead the container has a portion 120, 22A of reduced wall thickness which concertinas (or zig zags) when such a crushing force is applied.

1. A crush survival sharps container for a used syringe having an overall length and a needle with a needle tip, said container having a base, at least one side wall, a top, and a used syringe receiving aperture in said top closing said container and through which said used syringe can be passed, wherein a distance between said top and said base exceeds said overall length of said used syringe whereby said used syringe is wholly enclosed within said container when said used syringe is inserted into said container, each of said at least one side wall has a wall thickness which is greatest adjacent said base and thinnest adjacent said top, wherein a crushable portion of each of said at least one side wall adjacent said top concertinas when said container is subjected to a compressive crushing force in a direction generally from top-to-base, and wherein said base and a portion of each of said at least one side wall adjacent said base are sufficiently thick to prevent penetration thereof by a needle tip of a used syringe that has been inserted through said used syringe receiving aperture into said container and placed adjacent said base when said container is subjected to said compressive crushing force whereby said used syringe inserted through said aperture is retained within said container subjected to said compressive crushing force and said top, base and each said side wall of said container do not rupture. 2. The container as claimed in claim 1 wherein each of said at least one side wall tapers continuously in thickness from top to base. 3. The container as claimed in claim 1, wherein each of said at least one side wall tapers intermittently in thickness from top to base. 4. The container as claimed in claim 1, wherein said container has a transverse cross-sectional shape which is either generally circular or generally rectangular. 5. A method of providing a crush survival sharps container for a used syringe having an overall length and a needle with a needle tip, said container having a base, at least one side wall, a top, and a used syringe receiving aperture in said top closing said container and through which said used syringe can be passed, said method comprising: providing each of said at least one side wall with a wall thickness which is greatest in a portion adjacent said base and thinnest in a portion adjacent said top; and providing said base, and the portion of each of said at least one side wall adjacent said base, with a sufficiently thickness to prevent penetration thereof by a substantially vertically aligned needle of a syringe placed adjacent thereto, when said container is subjected to a compressive crushing force in a direction generally from top-to-base, wherein said container is subjected to said compressive crushing force, said portion of each of said at least one side wall adjacent said top concertinas, said used syringe inserted through said aperture is retained within said container subjected to said compressive crushing force, and said top, base and each said side wall of said container do not rupture. 6. The method as claimed in claim 5, including the further step of: continuously tapering the thickness of each of said at least one side wall from top to base. 7. The method as claimed in claim 5, including the further step of: intermittently tapering the thickness of each of said at least one side wall from top to base. 8. The container as claimed in claim 3, wherein each of said at least one side wall has a top portion adjacent said top, a bottom portion adjacent said bottom, and an intermediate portion located between said top and bottom portions, wherein the top and bottom portions each has a substantially constant thickness and the intermediate portion has a tapered thickness between the top and bottom portions. 9. The method as claimed in claim 7, wherein intermittently tapering the thickness of each of said at least one side wall further comprises providing each of said at least one side wall with a top portion adjacent said top, a bottom portion adjacent said bottom, and an intermediate portion located between said top and bottom portions, wherein the top and bottom portions each has a substantially constant thickness and the intermediate portion has a tapered thickness between the top and bottom portions.
