Abstract
Abstract A solvent and shatter resistant protector for glass bottles containing hazardous materials. The protector is comprised of opaque or transparent polymeric material and conforms substantially to the shape of the container to be protected. The container protector is made up of top and bottom portions each having respective cooperating means, such as a special threading arrangement, for separable engagement, which enables engagement to be maintained even in the event of experienced shocks sufficient to damage the protected glass container. The top portion has an aperture for providing access to the contents of the contents of the protected container without disengagement from the bottom portion.
