Blow-molded containers such as the 1.75-liter size for liquor beverages have an everting grip problem. Using inwardly facing grip geometry, consisting of two convex surfaces that come together at an inward ridge, eliminates the problem. The combination of the two convex surface sidewalls further eliminates the need for lateral reinforcing ribs in both cold-fill and hot-fill containers. The curved sidewalls come together at an edge offset the central axis of the container.
