Abstract
Abstract The present invention relates to new and improved, reusable mailer packages specially adapted for the safe transportation to a laboratory of a specimen, e.g., human blood, contained in a plurality of fragile test tubes and a fragile microscope slide, through the mails, regardless of the severity of rough handling to which the specimen mailer may be subjected. The complete mailer assembly comprises nested, elongated cylindrical plastic cups both of which are closed by end caps. The nested cups are disposed and maintained in a predetermined spaced relationship to one another by a cushioning disc spacer fabricated of a suitable resilient material such as expanded plastic foam. Disposed within the inner cylindrical plastic cup is a plastic divider structure which divides the inner cup into four test tube compartments and one microscope slide compartment.
