Abstract

A vial is described herein that comprises a tubular body which comprises an opened end, a closed end, and a cavity, wherein the opened end is located at one end of the tubular body and the closed end is located at an opposing end of the tubular body. The tubular body further comprises a tear line located therein, wherein the tear line extends across at least a portion of one side of the tubular body, across the closed end, and across at least a portion of another side of the tubular body. In addition, the tubular body further comprises two flanges extending from the closed end, wherein the two flanges are configured to separate from one another outwardly from the tubular body and apply a force to break-open at least a portion of the tear line to open at least the closed end of the tubular body.

First claim

What is claimed is:

1. A method for using a vial, the method comprising the steps of:
introducing a liquid sample into the vial, the vial comprising:
a tubular body comprising an opened end, a closed end, and a cavity, wherein the opened end is located at one end of the tubular body and the closed end is located at an opposing end of the tubular body;
the tubular body further comprises a tear line located therein, wherein the tear line extends across at least a portion of one side of the tubular body, across the closed end, and across at least a portion of another side of the tubular body; and
the tubular body further comprises two flanges extending from the closed end;

engaging the opened end of the tubular body with a cap to seal the vial;
freezing the liquid sample within the sealed vial;
separating the two flanges from one another outwardly from the tubular body to apply a force to break apart at least a portion of the tear line to open at least the closed end of the tubular body; and
ejecting the frozen liquid sample from the now opened closed end of the tubular body.

2. The method of claim 1 , wherein the tear line extends from below a threaded portion of the tubular body across the one side of the tubular body, across the closed end, and across the another side of the tubular body to below the threaded portion of the tubular body.

3. The method of claim 1 , wherein the tear line extends from a threaded portion of the tubular body across the one side of the tubular body, across the closed end, and across the another side of the tubular body and into the threaded portion of the tubular body.

4. The method of claim 1 , wherein the tear line bisects the tubular body.

5. The method of claim 1 , wherein the tear line is a localized thin section within the tubular body.

6. The method of claim 1 , wherein the tubular body further comprises one or more additional tear lines located therein and at least two more flanges two flanges extending from the closed end.
