Between the valve assembly and the collection container is a collection container attachment fitting for engaging the valve assembly with the collection container. The collection container attachment fitting can be a two-piece fitting designed to accommodate a flexible bladder used to accumulate multiple breath samples for subsequent delivery to the collection container.
