Abstract

Waste disposal device including a container defining a waste-receiving chamber, an insert defining a cavity receivable of a pack of flexible tubing for encapsulating waste packages and an inner lid connected to the container and selectively substantially covering or exposing an open top of the insert leading to the cavity. The inner lid and insert define a dispensing opening through which the tubing passes during use of the waste disposal device. An outer lid, optionally pivotally connected to the container, is movable between a position in which the waste-receiving chamber is accessible and a position in which the waste-receiving chamber is covered. A retention mechanism holds the waste package while a rotation mechanism causes rotation of the retention mechanism relative to the insert to cause a twist to be formed above a waste package when held by the retention mechanism and thereby encapsulate the waste package in the tubing.
