An oval plastic container. A cross-section of the container, taken perpendicular to the height of the container shows an oval or elliptical shape. Such a container has front and back sides. The container also has a left side and a right side. Given the oval shape of the body, the width of the container as measured from the left side to the right side, is less than the depth of the container, measured from front to back. The front and back of the container therefore have a relatively small radius of curvature, compared to the left and right sides. The front and / or the back of the container includes a relatively featureless panel. Such a panel is flat, apart from the curvature that results from the oval shape of the body. Such an area can be used for the application of a pressure-sensitive label. The oval shape of the body prevents the labeled surface from buckling during the cooling process. The left and right sides of the container may include structure such as ribbing, to prevent buckling or excessive deformation during cooling. Alternatively, the left and right sides of the container may include vacuum panels that may be drawn inward during cooling, without excessive deformation or buckling.
