Abstract
Abstract An assembly retains an element such as a filter in a vent opening of a waste disposal bag which can contain hazardous materials such as nuclear waste. The assembly includes a base plate and a cap plate. The base plate and cap plate cooperate to define a chamber for holding the filter element and to sandwich therebetween a portion of the bag adjacent the vent.
