Abstract
The present invention provides an improved blow molded plastic non-round container having generally rectangular sidewalls that are adapted for hot-fill applications. The hot-fill container has two adjacent sides one with a vacuum panel and the other with a series of ribs in the label mounting area on the sidewalls. The opposing sidewalls are symmetric relative to the vacuum panel and rib shape and placement. The ribs and vacuum panel cooperate to resist container upon filling and cooling and also improves bumper denting resistance, ease of manufacture and light weight capability.
