Odor containment

An odor-containment system for use with a flexible bag and a receptacle for holding waste items includes a body configured to be connected to the receptacle for holding waste items, the body providing a passageway through the body, and a plurality of sealing members attached, directly or indirectly, to the body and disposed across the passageway, the sealing members being disposed adjacent to each other in a static, closed position of the system such that a flexible bag inserted between the sealing members will be forced closed, where the body is configured to cover an opening of the receptacle for receiving the waste items, where the sealing members are attached to the body such that the sealing members can separate from each other to permit one of the waste items to be inserted between the sealing members, and where the sealing members are biased toward the static, closed position with the sealing members adjacent to each other such that when a waste moves out from between the sealing members, the sealing members will return to their static positions adjacent to each other.
