Abstract

A container into which used sharps can be deposited immediately following their use and carried to a second container into which the used sharps can be dumped for subsequent disposal without having to directly handle the sharps following their use. A top wall is normally latched closed and is opened to deposit used sharps into the container. A normally closed end wall is opened so that the used sharps can be dumped from the container. The container has a pistol-type grip for carrying it, and in a first embodiment a rearwardly biased pusher is slidably mounted in the container and moved forwardly by depressing a trigger on the grip. In a second embodiment, the pusher is biased forwardly and is latched in a rearward position. The trigger is connected with the latch to release it so the pusher can move forwardly.

First claim

What is claimed is:

1. A container into which used sharps can be deposited immediately following their use and carried to a second container into which the used sharps can be dumped for subsequent disposal without having to directly handle the sharps following their use, comprising:
a housing having a bottom wall, a front wall, a back wall, a top wall, a rearward end closed by a rearward end wall, and a forward end closed by a forward end wall;
said top wall being hinged to the back wall for pivotal movement between a closed position and an open position;
said forward end wall being hinged to the housing forward end for pivotal movement between a closed position and an open position;
first latch means engaged between said top wall and said front wall to latch the top wall closed, said top wall being openable to enable deposit of used sharps into the container and then latched closed to encase the used sharps in the container and prevent an accidental stick with the used sharps;
second latch means engaged between said forward end wall and said housing forward end to latch the forward end wall closed, said forward end wall being openable to enable the used sharps to be dumped from the container; and
a pusher slidably mounted in said container for movement from said rearward end toward said forward end to push used sharps from the container when said forward end wall is open.

2. A container as claimed in claim 1 , wherein:
said forward end wall is hinged at a bottom edge thereof to the bottom wall of said housing.

3. A container as claimed in claim 2 , wherein:
a pistol grip type handle is attached to the housing rearward end for carrying the container;
a depressible trigger is carried by said handle;
spring means is connected with the pusher to bias it toward the rearward end of the housing; and
means is connected between said trigger and said pusher to pull said pusher against the bias and toward the forward end of said container when the trigger is depressed.

4. A container as claimed in claim 1 , wherein:
said second latch means is at a bottom edge of said forward end wall, and said forward end wall is hinged at a top edge thereof to the top of said housing by a spring hinge that biases said forward end wall upwardly when the second latch means is released.

5. A container as claimed in claim 4 , wherein:
a pistol grip type handle is attached to the housing rearward end for carrying the container;
a depressible trigger is carried by said handle;
spring means is connected with the pusher to bias it toward the rearward end of the housing;
means is connected between said trigger and said pusher to pull said pusher against the bias and toward the forward end of said container when the trigger is depressed; and
said trigger is connected with said second latch means to disengage said second latch means when said trigger is depressed to enable said forward end wall to open so that said used sharps can be dumped from the container.

6. A container as claimed in claim 1 , wherein:
pneumatic means biases the pusher toward the forward end of the housing;
third latch means engages said pusher to hold it in place against the bias of said pneumatic means;
a handle is attached to the housing rearward end for carrying the container;
a depressible trigger is carried by said handle; and
means is connected between said trigger and said third latch means to release said third latch means so that said pneumatic means can move said pusher toward the forward end of said container when the trigger is depressed.

7. A container as claimed in claim 6 , wherein:
the pneumatic means comprises a piston reciprocal in a cylinder, said piston and cylinder defining a pressure chamber containing a fluid under pressure.

8. A container as claimed in claim 7 , wherein:
the piston is attached to the rearward end wall of the housing and is fixed against movement; and
the cylinder is attached to the pusher and moves toward the forward end of the housing to move the pusher toward the forward end of the housing when the third latch means is released.

9. A container as claimed in claim 8 , wherein:
said trigger is connected with said second latch means to disengage said second latch means when said trigger is depressed to enable said forward end wall to open so that the used sharps can be pushed from the container by said pusher.
