Abstract

A sharps container is disclosed. The sharps container utilizes a blocking member which does not interfere with a needle being inserted into the sharps container, and a latch mechanism which does not require a protruding tab. The latch mechanism requires at least a dual action to open the sharps container, and limits the movement required for opening the sharps container.

Claims

1. A sharps container comprising:

a first housing comprising a space, which accommodates at least one needle therein, and a first opening, dimensioned to receive at least one needle therethrough to be accommodated in the space; and

a breaking member comprising an engaging mechanism and a second opening dimensioned to receive the at least one needle therethrough;

wherein the second opening and the first opening overlap when in an open position to receive the at least one needle through the first opening and the second opening via an area of overlap between the first opening and the second opening;

a force is applied to the needle by moving at least one of the breaking member and the first housing relative to each other to reducing the area of overlap, whereby the needle is broken off when in a closed position;

the engaging mechanism comprises;

a first engaging member securing the first housing and the breaking member when in the closed position; and

a second engaging member securing the first housing and the breaking member when in the closed position; and

the open position is achieved by manipulating the first engaging member and the second engaging member.

2. The sharps container as claimed in claim 1, wherein

the first housing comprises at least one latch cam on an exterior surface the first engaging member comprises a first latch cam on the interior surface thereof,

the interior surface of the first engaging member facing the exterior surface of the first housing when in closed position;

the second engaging member comprises a second latch cam on the interior surface thereof, the interior surface of the second engaging member facing the exterior surface of the first housing when in closed position; and

at least one of the first and the second latch cam engages the at least one latch cam on the exterior surface of the first housing when in the closed position.

3. The sharps container as claimed in claim 2, wherein

the first housing comprises at least one other latch cam on the exterior surface thereof;

and

another of the at least one of the first and the second latch cam engages the at least one other latch cam on the exterior surface of the first housing when in the closed position.

4. The sharps container as claimed in claim 1, further comprising a spring mechanism which urges the breaking member with respect to the first housing in a direction facilitating the open position.

5. The sharps container as claimed in claim 1, wherein the open position is facilitated by essentially simultaneous manipulation of the first engaging member and the second engaging member.

6. The sharps container as claimed in claim 1, wherein the engaging mechanism comprises an exterior surface whose contour is essentially parallel to a contour of an exterior surface of the first housing when in the closed position.

7. The sharps container as claimed in claim 1, wherein

the first engaging member comprises a first exterior surface whose contour is essentially parallel to a contour of an exterior surface of the first housing when in the closed position;

and

the second engaging member comprises a second exterior surface whose contour is essentially parallel to the contour of the exterior surface of the first housing when in the closed position.

8. The sharps container as claimed in claim 1, wherein the first engaging member comprises a first interior surface facing an exterior surface of the first housing;

the second engaging member comprises a second interior surface facing the exterior surface of the first housing; and

the manipulating of at least one of the first engaging member and the second engaging member is limited, respectively, by a first distance between the first interior surface and the exterior surface of the first housing and by a second distance between the second interior surface and the exterior surface of the first housing.

9. A sharps container comprising:

a first housing comprising a space, which accommodates at least one needle therein, and a first opening dimensioned to receive at least one needle therethrough, to be accommodated in the space; and

a breaking member comprising an engaging mechanism and a second opening dimensioned to receive the at least one needle therethrough;

wherein the second opening and the first opening overlap when in an open position to receive the at least one needle through the first opening and the second opening via an area of overlap between the first opening and the second opening;

a force is applied to the needle by moving at least one of the breaking member and the first housing relative to each other to reduce the area of overlap, whereby the needle is broken off when in a closed position;

the engaging mechanism secures the first housing and the breaking member when in the closed position; and

the engaging mechanism comprises an exterior surface whose contour is essentially parallel to a contour of an exterior surface of the first housing when in the closed position.

10. The sharps container as claimed in claim 9, wherein

the engaging mechanism comprises a first lever and a second lever;

and

the open position is facilitated by manipulating the first lever and the second lever.

11. The sharps container as claimed in claim 10, wherein

the first housing comprises a first latch cam on an exterior surface thereof;

the engaging mechanism comprises a second latch cam on the interior surface thereof, the interior surface of the engaging mechanism facing the exterior surface of the first housing when in closed position;

the first latch cam engages the second latch cam when in the closed-position; and

disengagement of the first latch cam and the second latch cam is facilitated by the manipulating of the first lever and the second lever.

12. The sharps container as claimed in claim 11, wherein

the first housing further comprises a third latch cam on the exterior surface thereof;

the engaging mechanism comprises a fourth latch cam on the interior surface thereof;

the third latch cam engages the fourth latch cam when in the closed position;

the disengagement of the first latch cam and the second latch cam is facilitated by the manipulating of the first lever; and

the disengagement of the third latch cam and the forth latch cam is facilitated by the manipulating of the second lever.

13. The sharps container as claimed in claim 9, further comprising a spring mechanism which urges the breaking member with respect to the first housing in a direction facilitating the open position.

14. The sharps container as claimed in claim 10, wherein the open position is facilitated by essentially simultaneous manipulation of the first lever and the second lever.

15. The sharps container as claimed in claim 10, wherein:

the first lever comprises a first exterior surface whose contour is essentially parallel to a contour of an exterior surface of the first housing when in the closed position;

and the second lever comprises a second exterior surface whose contour is essentially parallel to the contour of the exterior surface of the first housing when in the closed position.
