Claim 1
Independent Claim
83 words
A carboy comprising a generally cylindrical shell having generally outwardly convex integral end closures, a substantially perimetric solid elastomeric skirt attached to each end closure, said skirt having an integral circumferentially extending rib portion immediately adjacent its associated end closure which projects radially outward from said end closure at least oneeighth inch, said end closure being equipped with a circumferential inward extending recess aligned with said projection to provide a substantial amount of elastomeric material in said rib portion for absorbing compressive shocks.
