Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
165 words
A pot and adapted to contain a yoghourt product subject to refrigeration comprising a molded plastic cup shaped body having an integral bottom and a continuous conical wall terminating in an open edge, said wall being formed of a thin material having a plurality of integral circumfrentially spaced-apart strip-like reinforcing zones extending between the bottom and said edge and having at least in part a directional component intersecting said edge and the bottom edge, each of said reinforcing zones having lateral edges which smoothly taper in a continuous transition to the flat remaining areas of the wall and having a width substantially smaller than that of the intervening flat walls whereby the define thin wall sections which are elastic and resistant to breakage and circumferentially spaced-apart reinforcing zones which provide container stiffness, said flat wall having a thickness of 0.3 mm and said reinforcing zones having a thickness of 0.7 mm, said bottom being formed with corresponding radial zones which merge with said reinforcing zones.
