Abstract
An air pocket is often formed in fluid (F) in the pitcher (14) of a blender around the rotating mixing blade assembly (24) thereof. The air pocket is of a cross-sectional size defined by an air channel defining member, shown in the form of a bearing housing (23) of the mixing blade assembly (24). After the pitcher (14) is filled with the fluid (F), the plunger portion (12) of an accessory (10) is positioned adjacent to and above the mixing blade assembly (24) and maintained free of contact with the pitcher (14). The plunger portion (12) is of a cross-sectional size approximately the cross-sectional size of the air channel defining member and prevents the formation of the air pocket in the fluid (F) around the blade assembly (24).
