An article, such as a container, includes a bottom wall, a sidewall and rim around a top end to strengthen the sidewall and to provide a handle for lifting the article. The rim includes a first lip extending radially outward with respect to the container to provide strength and rigidity to the rim and sidewall. The first lip is formed by two substantially parallel layers of material that can be spaced apart or bonded together. A second flexible lip extends radially from the rim and is axially spaced from the first lip. The second lip forms a continuous open channel enabling the second lip to be gripped from the inside of the article. The second lip has a radial dimension greater than the first lip to limit contact of the first lip with an adjacent object. An article is made by a blow molding process and apparatus having moving segment molds. A thermoplastic parison is inflated to contact the mold surfaces. The moving mold segments then compress a portion of the plastic to form the first lip.

[ What is claimed is:] [1.] A container comprising:a bottom wall;a sidewall extending about a center axis, said sidewall having a bottom end coupled to said bottom wall and an open top end spaced from said bottom end; anda continuous rim coupled to said top end of said sidewall, said rim including axially spaced first and second lips extending in a substantially radial direction with respect to said sidewall, said first lip being substantially flat and dimensioned in said radial direction to strengthen said sidewall and resist collapsing of said sidewall, said second lip forming a continuous channel around said sidewall, said channel having a continuous opening facing inwardly with respect to said container and having a radial dimension greater than a radial dimension of said first lip, said second lip being resilient and compressible to absorb impact from an object and resist contact of said first lip with said object;said container being made from a plastic material by blow molding.
