System for disposing waste packages such as diapers
First Claim
1. A diaper pail assembly, comprising:
- a housing;
a bag releasably mounted to said housing so as not to rotate with respect to said housing; and
a rotatable member for twisting a portion of said bag, said rotatable member comprising a plurality of flexible, inwardly extending fingers, said fingers having distal, radially innermost tip portions and base blade portions, wherein a thickness at the tip portions is thicker than at the base blade portions.

Abstract
Systems and methods for facilitating hygienic storage and disposal of waste packages such as used disposable diapers include a housing, a lid, and a bag unit having a bag frame and an attached single use flexible bag. The flexible bag is pleated and larger in cross-section at a lower portion than it is at the connection to the bag frame. The bag frame is releasably mounted to the housing so that it will not rotate. The lower portion of the flexible bag is positioned in a storage chamber of the housing that is shaped so as to align and center the bag. A rotatable member having radially extending flexible fingers is engaged with an intermediate portion of the bag. When the lid is closed, the rotatable member will twist the intermediate portion of the bag, sealing odors in the lower portion of the bag. A parent or caregiver will push the waste package through the resistance of the twisted intermediate portion into the lower portion of the bag, and close the lid to re-seal the twisted portion.
