Diameter:  The distance across an opening. The inner diameter is the maximum measurement from the inside of the opening, from one side to the other.  The outer diameter is the maximum measurement from the outside of the opening, including the bead and/or tearstrip and handle, if applicable.

Height: The measurement of the pail from the bottom of the chime to the top of the bead.  With cover engaged, the maximum dimension of the bottom of the pail to the top of the cover.

Satellite Rings: Horizontal ridges of plastic designed for increased top load and lateral strength.

Wall: The thickness of the part.  Wall thickness varies depending on the part construction and requirements.Cover

Chime: The ridge of plastic at the bottom of the pail that extends beyond the pail floor.

Bead: The rounded curl at the top of the pail designed for engagement with the undercut of the cover.

Ears: Pail feature on the side of the pail with opening for metal of plastic handle.

Gate: The recessed opening that allows the molten plastic to be injected into the cavity of the mold.

Injection point The small point at the center of the gate through which the molten resin is forced into the mold cavity.

Fitment: Any secondary option to a pail or lid construction such as spouts, screw caps or vents.

Fitment insert: Removable molding insert allowing for various options within the same molding component.Pail

Tear Strip: Removable strip of plastic to ease in opening and indicate tamper evidency.

Undercut: The ridge of plastic in the tear strip that ensures a snap seal over the pail bead.

Gasket: Rubber, foam or plastic inserted in the lid channel between the pail bead and lid for leak prevention.  Gasket material will depend on the application compatibility.

Lid Channel: Recessed opening in the outer perimeter of the lid designed to wrap the pail bead and engage the lid.

Reinforcement Ribs: Lateral ridges of plastic on pail chime and/or lid for increased strength.

Lid Recess: The horizontal drop from the lid ring to the flat lid panel.  Filled pail rests in the lid recess of the package for stack stability.
