Container having a rolled rim, and method of making the same

摘要

A blank for a container having a rolled rim, comprising a hollow body of polyolefin material, having an open first end and an opposite second end with a sidewall extending between the first end and the second end, and a rim formed at the first end of the hollow body. The rim includes a flange extending outwardly from the sidewall, the flange defining a flange thickness and having an inner portion proximate the sidewall and an outer portion opposite the inner portion. The rim further includes a skirt extending downwardly from the outer portion of the flange, the skirt defining a skirt thickness and having an upper portion proximate the flange and a lower portion opposite the upper portion, the flange thickness being greater than the skirt thickness.

1. A container having a rolled rim, comprising:
a hollow body of a thermoformed sheet consisting essentially of unfoamed polyolefin material, having an open first end and an opposite second end with a sidewall extending between the first end and the second end; a rigid rolled rim formed of the unfoamed polyolefin material at the first end of the hollow body, the rigid rolled rim including a flange extending outwardly from the sidewall, the flange defining a flange thickness and having an inner portion proximate the sidewall and an outer portion opposite the inner portion, the rigid rolled rim further including a skirt extending downwardly from the outer portion of the flange toward the sidewall, the skirt defining a skirt thickness and having an upper portion proximate the flange and a lower portion opposite the upper portion, the flange thickness being greater than the skirt thickness.
