Abstract
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.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
110 words
A closure device for closing the open ends of an array of mutually spaced receptacles, said closure device comprising: a flexible cover configured and dimensioned to overlie said receptacles; and an array of hollow caps formed integrally with and depending from said cover, said caps being positioned to enter and close the open ends of said receptacles, said caps having cup shaped noses with cylindrical side walls joined to said cover by intermediate wall sections, said intermediate wall sections having outer surfaces which taper inwardly from said cover to said cylindrical side walls and which are dimensioned to create singular interference fits with said receptacles within the open ends thereof.
Claim 2
Dependent Claim
110 words
A closure device for closing the open ends of an array of mutually spaced receptacles, said closure device comprising: a flexible cover configured and dimensioned to overlie said receptacles; and an array of hollow caps formed integrally with and depending from said cover, said caps being positioned to enter and close the open ends of said receptacles, said caps having cup shaped noses with cylindrical side walls joined to said cover by intermediate wall sections, said intermediate wall sections having outer surfaces which taper inwardly from said cover to said cylindrical side walls and which are dimensioned to create singular interference fits with said receptacles within the open ends thereof.
