A waste disposal container for soiled items includes a container body, a lid over a top opening of the container body, and one or more diaphragms and a retaining ring installed inside the container body. A step feature is formed on the interior surface of the container body below the top opening. The diaphragms and the retaining ring rest on the step feature. Each diaphragm is a disk shaped member made of a flexible and resilient material such as rubber, and is partitioned into a plurality of wedge shaped sections by a plurality of radial cuts. Two or more diaphragms may be overlapped and their cuts are offset with respect to each other. The retaining ring is disposed above the diaphragms. In use, a disposable bag is placed inside the container and is held at its top between the container body and the diaphragms and the retaining ring. |
