Patent ID: 7632467

Claim:
A unitary array of a plurality of miniature shelf keeping units, comprising: a substantially planar one-piece molded tray including a plurality of integrally molded tube structures, each of said tube structures having a selected outside diameter, said tray having an upper surface and a plurality of side walls carried in a substantially perpendicular orientation with respect to said upper surface; each said integrally molded tube structure defining a hollow cavity terminated at a distal end in a closed, fluid tight boundary and terminated at a proximal end in an opening in fluid communication with said tube hollow cavity; said tube proximal end openings being aligned in a plane that is substantially co-planar with said tray upper surface; and a pair of flexible circumferentially-spaced rabbit ear-shaped prongs projecting angularly downwardly and outwardly at the distal end of said tube, whereby when a tube is inserted in apertures of a receiving plate, the prongs are pressed radially inwardly to engage shoulder surfaces of a recess at the bottom of the apertures in the receiving plate to facilitate easy withdrawal and replacement of tubes in the apertures when performing automated testing.
