Abstract

A closure device is provided which includes a flexible cover with an array of protruding hollow caps which are formed integrally with and depend from the cover. The caps have cup shaped noses with cylindrical side walls joined to the cover by inwardly tapered intermediate wall sections. The caps form a friction fit with an array of mutually spaced receptacles, for example test tubes, deep well blocks or microwell plates.
