Abstract

A waste disposal system with a waste receiver for receiving pharmaceutical waste material. A locking assembly is secured to a fixed surface and actuated from a locked configuration to an unlocked configuration. A lock cylinder of the locking assembly may extend forward of a front wall of a receiver body of the waste receiver to engage a locking feature of the cover in the locked configuration. A cover retention feature may prevent axial decoupling of the cover from the receiver body. An engagement feature is moved to be disengaged from the receiver body, and the receiver body is moved away from the fixed surface to disengage the locking assembly from the cover. The cover is decoupled from the cover retention feature, and coupled with the receiver body to seal the pharmaceutical waste material. The locking assembly may be removed from a lock passageway for disposal of the waste receiver.

First claim

What is claimed is:

1. A method of disposing of a waste receiver including a cover coupled to a first cover retention feature of a receiver body with the receiver body defining an opening for receiving pharmaceutical waste material and a container volume in fluid communication with the opening, wherein a second cover retention feature is disposed on the receiver body near the opening, wherein front and rear walls of the receiver body further define a lock passageway separate from the opening, wherein the waste receiver is coupled to a locking assembly secured to a fixed surface in a locked configuration in which a lock housing of the locking assembly is positioned at least partially within the lock passageway and an engagement feature of the locking assembly engages the receiver body to prevent removal of the waste receiver from the locking assembly, said method comprising the steps of:
actuating the locking assembly from the locked configuration to an unlocked configuration in which the engagement feature is moved to disengage from the receiver body and the receiver body is moved away from the fixed surface to disengage the locking assembly from the cover, wherein the first cover retention feature maintains coupling between the cover and the front wall of the receiver body;
providing an input to the cover to decouple the cover from the first cover retention feature of the receiver body;
coupling the cover with the second cover retention feature of the receiver body to cover the opening to seal the pharmaceutical waste material within the receiver body;
removing the waste receiver from the locking assembly; and
disposing of the waste receiver.

2. The method of claim 1 , wherein the first cover retention feature are threads, wherein the step of providing an input to the cover further comprises rotating the cover relative to the receiver body to decouple the cover from the threads.

3. The method of claim 1 , wherein the locking assembly further includes a biasing member disposed in a stored energy state in the locked configuration, wherein the biasing member provides a biasing force to move the receiver body away from the fixed surface in the unlocked configuration.

4. The method of claim 3 , wherein the cover includes a cover body and a locking feature coupled to the cover body with the locking assembly engaging the locking feature of the cover to prevent rotation of the cover relative to the receiver body in the locked configuration.

5. The method of claim 4 , wherein the locking assembly includes a lock cylinder coupled to the lock housing and extending forward of a front of the receiver body to engage the locking feature in the locked configuration.

6. The method of claim 5 , wherein the lock cylinder extends forward of the front of the receiver body by a first distance in the locked configuration, wherein the biasing member moves the receiver body away from the fixed surface by a second distance greater than the first distance to disengage the locking feature of the cover from the lock cylinder of the locking assembly.

7. The method of claim 1 , wherein the step of coupling the cover with the receiver body is performed while the lock housing is positioned at least partially within the lock passageway.

8. The method of claim 1 , further comprising the steps of:
providing a second waste receiver including a second cover and a second receiver body defining a second lock passageway;
positioning the lock housing within the second lock passageway to couple the second receiver body and the locking assembly such that the engagement feature engages the second receiver body; and
actuating the locking assembly from the unlocked configuration to the locked configuration.

9. The method of claim 8 , wherein the second cover is coupled to the second receiver body prior to and during the step of positioning the lock housing within the second lock passageway.

10. The method of claim 8 , wherein each of the second lock passageway and the lock housing are oblong in shape, said method further comprising the step of aligning the complementary oblong shapes of the second lock passageway and the lock housing to orient the second waste receiver relative to the locking assembly in a single orientation.

11. A waste receiver for receiving pharmaceutical waste material and adapted to be releasably coupled to a locking assembly secured to a fixed surface, said waste receiver comprising:
a receiver body defining an opening for receiving the pharmaceutical waste material and comprising an inner surface defining a container volume in fluid communication with said opening, and an outer surface opposite said inner surface, wherein said inner and outer surfaces form at a front wall, a rear wall opposite said front wall, and opposing sidewalls extending between said front and rear walls with apertures within said front and rear walls defining a portion of a lock passageway adapted to receive the locking assembly;
a fluid absorber disposed within said receiver body;
a chemical composition disposed within said receiver body;
a first cover retention feature coupled to said front wall of said receiver body;
a second cover retention feature on said receiver body near said opening; and
a cover coupled to said first cover retention feature, wherein said cover is configured to be decoupled from said first cover retention feature and coupled with said second cover retention feature to be positioned over said opening and seal the pharmaceutical waste material within said container volume for disposal of said waste receiver.

12. The waste receiver of claim 11 , wherein said first cover retention feature is a boss extending forward from said front wall, and threads disposed on an outer surface of said boss with said threads configured to prevent axial decoupling of said cover from said receiver body.

13. The waste receiver of claim 12 , wherein said cover comprises a cover body, a rim defining an outer surface of said cover body, and a locking feature extending radially outwardly from said rim.

14. The waste receiver of claim 13 , wherein said locking feature is a U-shaped flange sized to receive a lock cylinder of the locking assembly to prevent rotational decoupling of said cover from said receiver body when said waste receiver is releasably secured to the locking assembly.

15. The waste receiver of claim 14 , wherein said first cover retention feature cooperates with complementary features of said cover to position said locking feature adjacent said lock passageway when said cover is coupled to said receiver body.

16. The waste receiver of claim 12 , wherein said cover comprises a cover body defining a concave cavity sized to receive said boss when said cover is coupled with said threads.

17. The waste receiver of claim 12 , wherein said threads of said first cover retention feature are circumferentially spaced about said outer surface of said boss.

18. The waste receiver of claim 12 , wherein at least a portion of said lock passageway extends through said boss.

19. The waste receiver of claim 11 , wherein each of said first and second cover retention feature are threads configured to engage complementary threads of said cover.

20. The waste receiver of claim 19 , wherein said second cover retention feature further comprises teeth configured to prevent decoupling of said cover once said cover is coupled with said second cover retention feature.
