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.


Bottle Anatomy
  • Mouth - The opening at the top of a container
  • Neck Finish - The area of a container that holds a cap or closure. visit our neck finish info page for more information.
  • Shoulder - The sloped area of a container between the neck and body with a curved radius

  • Label Panel - A flat area upon which a label can be applied. Typically 1/8" to 1/4" down from the shoulder and up from the base
  • Wall - The thickness of the container, which is typically measured along the sides
  • Base - The bottom of a container, which has a curved radius

A plastic or glass bottle is considered to be:
Round when the container's horizontal cross section or base is a circle.
Oval when the bottle has an oval-shaped base
Oblong when the bottle has a rounded rectangular base
