Capillary action collection device and container assembly

摘要

A container assembly is disclosed including an outer container, a hollow inner member, and a closure. The outer container has a closed bottom, an open top, and a sidewall extending therebetween. The hollow inner member is disposed within the outer container and has an inner surface defining at least one capillary channel. The inner member includes a first end adjacent to the open top of the outer container and has an outer periphery seated against the sidewall of the outer container. The closure has a proximal end and a distal end. The closure proximal end is seated at least partially within the first end of the inner member to seal the outer container and inner member and define a fluid collection chamber. The closure distal end defines a recessed area shaped to direct fluid under capillary action to the at least one capillary channel in the inner member.

主权项

1. A container assembly comprising:
an outer container comprising a closed bottom, an open top, and a sidewall extending between the closed bottom and the open top, the closed bottom, the open top, and the sidewall defining an interior of the outer container; a hollow inner member disposed within the interior of the outer container and having an inner surface defining at least one capillary channel, the inner member comprising a first end adjacent the open top of the outer container, a second end, and an outer sidewall extending between the first end and the second end, the outer sidewall seated against the sidewall of the outer container; and a closure having a proximal end and a distal end, the proximal end of the closure seated at least partially within the first end of the inner member and concurrently within the outer container to seal the inner member and the interior of the outer container and define a fluid sample chamber, the distal end of the closure defining a recessed area shaped to direct fluid under capillary action to the at least one capillary channel in the inner member.
