Abstract

An infectious waste container for blood collection needles comprises a container body (1) for containing blood collection needles, a lid body (2) attached to the container body (1), and needle-removing means (3) attached to the lid body (1) for removing a blood collection needle from a blood collection needle holder, the needle-removing means having a holder insertion section (31) and a holder suspension section (32) and being axisymmetrially provided with first and second notched portions (33, 34) extending from the holder insertion section to the holder suspension section. The first notched portion is stretched to a downwardly slanted portion protruded inwardly from a bottom of the first notched portion, the second notched portion is extended to a position deeper than a level of the slanted portion by a certain distance and terminated within the holder suspension section.

Claims

1. An infectious waste container for blood collection needles, comprising:

a container body with a mouth at a top thereof;

a lid body attached to the mouth of said container body and provided in a top wall thereof with an opening; and

needle-removing means arranged in the opening of said lid body for removing a blood collection needle from needle fixing means of a blood collection needle holder;

said needle-removing means comprising a cylindrical member including a holder insertion section and a holder suspension section, said holder insertion section being so formed as to have an inner diameter larger than an outer diameter of said holder, while said holder suspension section being so formed as to have an inner diameter smaller than the outer diameter of said holder, said cylindrical member being axisymmetrially provided with first and second notched portions extending from the holder insertion section to the holder suspension section, said first notched portion being stretched to a downwardly slanted portion protruded inwardly from a bottom of said first notched portion, said first notched portion being terminated at a level where the needle fixing means of said holder does not come into contact with the inner wall of the cylindrical member when said holder is inserted thereinto, while the second notched portion being so formed as to be deeper than the level of the slanted portion by a certain distance and terminated within the holder suspension section.

2. The infectious waste container according to claim 1, wherein said opening of the lid body is provided with a covering means.

3. The infectious waste container according to claim 1, wherein said covering means is a freely removable cap provided with at least one rib at a outer wall of its skirt portion.

4. The infectious waste container according to claim 1, wherein said covering means is a lid member adapted to open and close the opening of the lid body, said lid member having a fixing portion for engagement with the lid body and being connected to the fixing portion with a connecting portion.

5. The infectious waste container according to claim 1, wherein said lid member is provided with a grip portion and wherein the top wall of the lid body is provided with engaging means projecting therefrom so that the lid member is lightly engaged with the lid body.

6. The infectious waste container according to claim 1, wherein said grip portion is provided with a projection, and wherein the top wall of the lid body is provided with a hole in which said projection is fitted so that the covering means closes the lid body firmly.
