Capillary action collection device and container assembly

A container assembly comprising:

• a collection container having a closed bottom, an open top, and a sidewall extending therebetween defining an interior;
• a closure seatable at least partially within the open top of the collection container;
• and
• a wall element disposed within the interior of the collection container and adapted to compress radially inward under centrifugal force applied to the container assembly in which the wall element defines a floor of the interior, the wall element adapted to move downward within the interior from a first position in which the wall element is spaced a first distance away from the top of the collection container to a second position in which the wall element is spaced a second distance away from the top of the outer container, the second distance being greater than the first distance,
• wherein the interior is spaced from the closed bottom of the collection chamber, and wherein the wall element has an interconnecting wall structured to prevent the flow of fluid from the interior to the closed bottom of the collection chamber.

A container assembly, comprising:

• a collection container having a bottom, an open top, and a sidewall extending therebetween defining an interior;
• a closure seatable at least partially within the open top of the collection container;
• and
• a wall element disposed within the interior of the collection container in which the wall element defines a floor of the interior, the wall element movable from a first position in which the wall element is spaced a first distance away from the top of the collection container to a second position in which the wall element is spaced a second distance away from the top of the outer container, the second distance being greater than the first distance, under the application of a centrifugal force applied to the wall element in a direction away from the open top towards the bottom,
• wherein the floor of the interior is spaced from the bottom of the collection chamber, the wall element having an interconnecting wall structured to prevent the flow of fluid from the interior to the bottom of the collection chamber.

A container assembly comprising:

• an outer container comprising a closed bottom, an open top, and a sidewall extending therebetween;
• a hollow inner member disposed within the outer container and having an inner surface, the inner member comprising a first end adjacent to the open top of the outer container and having an outer periphery seated against the sidewall of the outer container and a second end;
• a closure seated at least partially within the first end of the inner member to seal the outer container and define a fluid sample chamber;
• and
• a wall element adapted to seal against the inner surface of the inner member in which the wall element defines a floor of the fluid sample chamber and adapted to move within the inner member from a first position in which the wall element is spaced a first distance away from the top of the outer container to a second position in which the wall element is spaced a second distance away from the top of the outer container, the second distance being greater than the first distance, under centrifugal force applied to the container assembly,
• wherein the inner member defines an internal rim at a transition location between a first internal diameter and a second internal diameter and the wall element is seated in engagement with the internal rim, and wherein upon application of centrifugal force the wall element compresses radially inward sufficiently to unseat from the internal rim.
