Abstract
A container assembly is provided for collecting capillary blood from a lanced wound. The container includes an integral lip for facilitating collection from the wound with the entire length of the container from lip to curved closed end being substantially the same large diameter for rapid collection before coagulation. The container includes an annular integral skirt enclosing the rounded bottom of the container to provide an annular stable surface for maintaining the container upright on a flat surface to facilitate subsequent examination of the collected blood. A cap for the assembly includes an annular space for receiving the top edge of the container in sealing engagement. This same annular space in the cap receives the annular bottom surface of the container skirt to join the two parts together when the container is open. The cap, in turn, includes an annular skirt for holding the open assembly in stable erect position on a flat surface. One form of the cap includes an expanded skirt for enclosing an annular flange extending from and adjacent to the top edge of the container, the latter being for the purpose of increasing the cooperating surfaces between the cap and the conta…
