Lids and fill caps

• Blender lids are usually made of rubber and often contain a hole in the center for a plastic fill cap. The fill cap is a removable insert that allows more items to be added to the jar without removing the entire lid.

Jar

• The blender jar is the main unit into which the items intended for blending are placed. They can be made of glass or plastic and are topped off with a lid. They are held in place at the bottom with a jar base.

Jar base

• This round unit with a hole in the center screws onto the bottom of the blender jar. Blades are placed atop the jar base as the jar base is screwed into place, and they are then placed on top of the blender's base.

Blades and gasket

• Blender blades are usually constructed of stainless steel and consist of two or more blades held in place by a central piece the whirls around for cutting. Blades are made leak proof by the rubber ring, known as the seal ring or gasket, that sits between them and the bottom of the blender jar.

Base

• The blender base is the mechanical heart of the unit and houses a motor that turns the blades. The base holds the jar in place and is outfitted with controls to adjust the speed and type of blending desired.
