Abstract: A collapsible and expandable toy container includes a base member configured for placement on a support surface, a sidewall extending upwards from the base member, a top member, and an interior space configured for holding one or more accessory items. A telescoping column supports the top member from the base member. The column is vertically extendible and retractable relative to the base member. At least one spring biases the column towards its extended position which raises the top member to access the interior space. Openable/closeable doors provides alternate access to the interior space. An optional intermediate platform may be arranged on the column between the top and base members. In the collapsed condition with doors closed, the container resembles a can and conceals any accessory items in the interior space. In the expanded condition, the container provides a multi-level play experience with play surfaces at different elevations for the child.
