摘要

The stackable cup or glass (1) has a base (2) along the edge of which is an upright peripheral wall (3) defining a mouth aperture (4). The base also has at least one groove (5) equal in shape to at least part of the edge of the mouth aperture. Four grooves are provided in the base, which are partly circular in shape. The cups are thin-walled and when they are stacked, the mouth edge falls into a groove in the base, thus creating a more stable stacking arrangement.
