Abstract: A fluid collection apparatus is disclosed which is useful in separating blood serum or plasma from blood cellular and particulate matter. The apparatus includes an elongate hollow body having a self-sealing septum sealingly disposed within one end thereof and a piston having an axially projecting hollow piercing element adapted to pierce the septum and provide communication with the interior of the hollow body. The piston includes a laterally extending flange for sealing engagement with the interior of a container for containing the mixture to be treated. After the hollow body and the associated piston assembly is inserted into the container the flange of the piston is engaged with the inner wall of the container causing the composite piston apparatus to remain in and seal a sample within the container.

Abstract: An improved, dual-seal, ball-type dispensing package combination for cosmetics and the like. A dispensing ball is held in place in a fitment which is adapted to be attached to the finish portion of a container for the product to be dispensed. The ball is allowed to move freely within the fitment to facilitate uniform dispensing and application of the contents of the container. The total package is completed by a closure which engages threads on the exterior of the finish portion of the container. The closure, fitment, and ball cooperate to create a seal between the fitment and ball at two separate locations to prevent leakage of product when the closure is placed into full engagement with the container.
