Application number: 20030097824
Abstract: Method and apparatus for applying seals made of
thin material to the open tops of containers, e.g., specimen containers for holding biological fluid that are processed automatically.
A measured length of sealing material is advanced across and pressed against the top of the container to effect a seal. Depending
on the type of sealing material used, sealing may be accomplished by application of pressure alone, by application of heat and pressure,
or by application of ultrasonic energy and pressure. Excess sealing material optionally may be folded against the container sides
by means of a folding member adapted to surround a container when the sealing head is lowered. Motor-driven rollers advance the sealing
material, while a platen on a movably mounted sealing head presses the sealing material into engagement with the container.

Abstract: Method and apparatus for storing and dispensing articles,
one at a time, from the bottom of a stack of like articles. The articles are yieldably supported in at least one upright stack above
an outlet, e.g., a resilient choke, sized to pass the articles if forced therethrough. Articles are dispensed by pressing downwardly
on the stack with sufficient force and for sufficient duration to overcome the yieldable supporting force and move the lowest article
through the outlet. Sensors may be provided for sensing when an article is dispensed, when the tube is empty, and the type of article
in the holder. The method and apparatus are especially useful in a vial-based automated system for processing multiple specimens of
biological fluid, wherein a filter assembly must be dispensed into a filtration chamber associated with each specimen vial.
