Abstract
Abstract A container for packaging fragile articles such as vials in a suspended state between two flexible membranes. An absorbent material is placed in compartments for the vials and is in fluid communication with the vials in case of breakage and spillage of fluid therefrom. In a preferred embodiment, the absorbent material extends upwardly along a compartment wall so as to be in close communication with one of the membranes. This affords a faster wicking action even if spillage should occur when the container is upside-down.

Total Claims: 16
Claim 1
Independent Claim
178 words
A container for at least one fragile article comprising: a tray portion and a cover portion each including an outwardly extending and continuous peripheral wall encompassing cavity portions, said peripheral wall of said tray and cover portion constructed and arranged to present the cavity portions in a face-to-face relationship; partitions extending between opposing sides of said tray portion to define in part at least one open compartment; an absorbent material in said compartment; a first flexible membrane disposed between said partitions in a hammock like manner to support said fragile article; and a second flexible membrane disposed over said cavity portion in said cover portion; said flexible membranes providing a fluid dampening effect for said fragile article placed on said first flexible membrane disposed between said partitions when said tray portion and said cover portion are engaged, and said first flexible membrane spaced from said tray walls to provide a fluid passage to said absorbent material with a major portion of said absorbent material being disposed on a side of said first flexible membrane opposite said fragile article.
Claim 2
Dependent Claim
