A package includes a container having a closed bottom, an open top having an outwardly extending flange, and a body having an enclosed generally cylindrical perimeter surrounding a longitudinal axis between the bottom and the top. The body can include an opposed pair of longitudinally extending inward protrusions forming a graspable handle dividing the body into a front label surface occupying at least 180&#xb0; of the body and a back label surface smaller than the front label surface. Each inward protrusion can include a plurality of longitudinal ridges on a forwardly facing surface to facilitate single handed grasping of the package. A plurality of circumferential ribs can be situated between an upper end of the inward protrusions and the outwardly extending flange to preserve the package shape during storage on commercial food storage racks.

Plastic can package

An extrusion blow mold for forming a plastic bottle having a radial flange suitable for roll-form attachment to a metal can end. The mold has a pair of confronting mold halves, each mold half including a body forming portion, a bottom pinch-off portion located below the body forming portion, a top block portion including a blow chamber located above the body forming portion, and a spin-ring forming portion located between the body forming portion and the top block portion. The spin-ring forming portion includes a thread ring insert and a cutter ring insert. The thread ring insert has an inside upper edge including an outwardly extending surface terminating in a step defining a lower surface and a outer edge of a radial flange. The cutter ring insert is positioned immediately above the thread ring insert. The cutter ring insert has a lower surface adjacent an inside edge defining an upper surface of the radial flange including a tapered inner edge extending upward and inward from the step. At least one of the thread ring insert and cutter ring insert includes a relief surface connected to a vent channel to permit gas to escape from the area defining the radial flange.
