Abstract
Embodiments are directed to filtration container assemblies and methods of using the same. A filtration container assembly includes an outer container and a plunging assembly. The plunging assembly includes an inner sleeve, a filtration assembly, and a cap assembly having a pressing surface. When the outer container is at least partially filled with liquid, a user can exert pressure on the pressing surface of the plunging assembly to nest the plunging assembly within the outer container, using positive pressure to displace the liquid in the outer container through the filtration assembly into the inner sleeve. In some embodiments, at least a portion of a handle for the filtration container assembly may be a part of the pressing surface.
