Abstract

A liquid vial assembly comprises a liquid-containing vial having a seamless cylindrical wall and a transparent outer sleeve extending along the wall. The resistance of the vial to breakage is dramatically improved. The sleeve may be made of a resilient material capable of being slightly stretched (PVC tubing, for example) or of a hard material such as polycarbonate or tempered glass. Either material is preferably non-shatterable. A new method for making a liquid vial assembly is also disclosed.
