MEDICAL WASTE CONTAINER LID
The present invention provides a lid for a waste container having a first portion pivotably connected to a second portion. The first portion includes a first handle and a first protrusion and the second portion includes a second handle and a second protrusion. The first protrusion engages the second protrusion to prevent the first portion from rotating relative to the second portion past a threshold angle.
This application claims priority to U.S. Provisional Application No. 61/088,871 which was filed on Aug. 14, 2008.
BACKGROUND OF THE INVENTIONThis disclosure generally relates to a lid for a medical waste disposal container. More particularly, this disclosure relates to a lid for accessing only a portion the waste container or the entire waste container.
Many types of containers have been used to store medical waste and protect the patient or health care professional from the waste product stored inside the container. The waste product may include biological material, medical devices, or other similar materials. It is important for the user disposing of the medical waste product to easily access the interior of the container to dispose of the medical waste.
SUMMARY OF THE INVENTIONThe present invention provides a lid for a waste container having a first portion pivotably connected to a second portion. The first portion includes a first handle and a first protrusion and the second portion includes a second handle and a second protrusion. The first protrusion engages the second protrusion to prevent the first portion from rotating relative to the second portion past a threshold angle.
In the particular example shown, the lid and container assembly include a lid and a container having an interior and an upper perimeter. The lid includes a first portion having a first protrusion, a second portion having a second protrusion, and a channel formed around a perimeter of the lid for accepting the upper perimeter of the container.
The lid is removed from the container by engaging a first handle on a first portion and a second handle on a second portion of the lid and applying a lifting force to the first handle and the second handle. A first protrusion on the first portion engages a second protrusion on the second portion of the lid to prevent the first portion from rotating relative to the second portion past a threshold angle.
The various features and advantages of the disclosed examples will become apparent to those skilled in the art from the following detailed description. The drawings that accompany the detailed description can be briefly described as follows:
An example container 10 and lid 32 for collecting medical waste is shown in
The container 10 includes a base wall 12, side walls 14, a front wall 16, a rear wall 18, and a pair of container flaps 19 hingeably connected to upper edges of the side walls 14. Handles 22 protrude outwardly from the front wall 16 and the rear wall 18.
An inner wall 48a extends upwardly from a perimeter 50a of the lower surface 42a to an intermediate surface 52a along the front portion 34a and to the upper surface 46a along the side portions 38a and the rear portion 36a. An outer wall 54a extends downwardly from an outer edge 56a adjacent the side portions 38a and the front portion 34a. A first protrusion 58a extends downwardly from the outer edge 56a of the upper surface 46a adjacent the rear portion 36a. The first protrusion 58a includes an outwardly facing surface 60a. The first portion 32a and the second portion 32b are identical and can be produced from the same mold. The lid 32 may be thermoformed or injection molded. The lid 32 may also be reusable or recyclable.
A channel 66a, 66b is formed between the inner wall 48a, 48b and the outer wall 54a, 54b. The first and second protrusion 58a, 58b are spaced from the outer wall 54a, 54b to create a channel opening 68 to allow the upper hinge portion 26 of the container 10 to mate with the channel 66a, 66b. The channel 66a, 66b is deeper along the side portions 38a, 38b to accommodate the greater height of the upper hinged portion 26 on the side walls 14 and shallower along the front portion 34a, 34b to mate with the generally flat upper edge 28 of the front wall 16 and the rear wall 18. However, the depth of the channel 66a, 66b may vary to accommodate different containers 10. The inner wall 48a, 48b and the outer wall 54a, 54b along the front portion 34a, 34b of the lid 32 may engage the front wall 16 or the rear wall 18 to prevent the lid 32 from sliding on the container 10 when opening either the first portion 32a or the second portion 32b. The channels 66a, 66b, or portions thereof, may be slightly narrower than the upper edges of the front wall 16, rear wall 18 or side walls 14, such that the walls 48a, 48b and 54a, 54b are deformed slightly when installed to further retain the lid 32 on the container 10. Alternatively, or in addition, a snap-fit connection between the lid 32 and container 10 could be provided.
A first side 70 of the container 10 is accessed by engaging the protruding handle 40a on the first portion 32a and rotating the first portion 32a about axis of rotation A as shown in
Alternatively, access to the entire opening 30 of the container 10 is obtained by simultaneously grasping with one hand the pockets 44a 44b on the lid 32 and applying a vertical lifting force to remove the lid 32. The first outwardly facing surface 60a on the first protrusion 58a engages the second outwardly facing surface 60b on the second protrusion 58b to maintain the lid 32 in a substantially flat orientation while allowing the pockets 44a 44b to be engaged by a single hand for removal. Note that in
In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
Claims
1. A lid for a waste container comprising:
- a first portion pivotably connected to a second portion;
- the first portion including a first handle and the second portion including a second handle; and
- a first protrusion extending from the first portion and a second protrusion extending from the second portion wherein the first protrusion engages the second protrusion to prevent the first portion from rotating relative to the second portion past a threshold angle.
