Container Styles Guide


Our Container Styles info page defines common bottle and jar terminology to help you select the right container. The image below explains basic container "anatomy", to which we will refer throughout this article.


A plastic or glass bottle is considered to be round when the container's horizontal cross section or base is a circle. An oval bottle has an oval-shaped base while an oblong bottle has a rounded rectangular base.
