Collapsible container with durable bottom shell |
摘要 |
A collapsible container includes a cylindrical sidewall extending between a top and a bottom of the container. The sidewall is formed of a flexible material which enables the container to be opened to an expanded configuration or closed to a collapsed configuration. A coil spring biases the container to the open configuration. The coil spring has a top coil adjacent the top of the container and a bottom coil adjacent the bottom of the container. A durable bottom layer is affixed to the bottom of the container.
