Abstract
An expandable bank is disclosed which includes a rigid metallic, ceramic or plastic body which is provided with a plurality of support legs, an upper coin slot and a bottom opening. A flexible material pouch or expander is removably affixed over the bottom opening to define an interior, expandable coin receiving compartment. As coins are introduced into the bank through the upper coin slot, the coins fall on the flexible material pouch and the weight of the coins causes the pouch to expand, thereby giving visual evidence of the approximate number of coins contained within the bank. The flexible material pouch is secured about the bottom opening with a reusable fastener. The bank can be repeatedly filled and emptied by first applying the flexible material pouch to the rigid body then filling the bank with coins, separating the fastener to remove the coins and then reapplying the flexible material pouch by using the fastener.
