Extraction vial
First Claim
1. A vial suitable for use with an extraction liquid, comprising:
- a reservoir portion defining a chamber consisting of a pair of spaced, flat, generally parallel walls, the walls being compressible;
a neck portion integral with the reservoir portion at a first end of the reservoir portion, the neck portion defining an opening into the reservoir portion and a channel surrounding the opening;
a nozzle portion integral with the reservoir portion at a second end of the reservoir portion, the nozzle portion narrowing to a leading end and including a passage connecting with the chamber and the leading end;
a sealing closure connected to the leading end by a line of weakness so as to close the leading end;
a base integral with the sealing closure located opposite from the nozzle portion, the base including a support surface generally perpendicular to a central axis of the vial for stably supporting the vial in a generally vertical, upright position;
a support tab integral with and extending between the nozzle portion and the base; and
a cap including a portion adapted to be snugly received and removably rigidly maintained within the channel.

Abstract
An extraction vial includes a reservoir portion having generally parallel walls, a neck portion defining an opening into the reservoir portion and a channel surrounding the opening, a nozzle portion integral with reservoir portion at a second end of the reservoir, a sealing closure that closes the nozzle, a base integral with the sealing closure and including a support surface adapted to support the vial in an upright position, and a cap received and removably maintained within the channel. An extraction liquid may be contained within the vial for extracting sample from a carrier. The vial may be used by adding the carrier to the extraction liquid within the vial, closing the vial with the cap, agitating the vial to release sample from the carrier, and removing at least the sealing closure or, preferably, the sealing closure and base whereby extraction liquid can be expelled from the vial.
