ABSTRACT:
A collapsible frame for supporting a container is manufactured from two loops formed from a single length of wire which are intertwined to form a handle and sprung to form base members which are yieldably urged apart. An inwardly narrowed neck portion is formed intermediate the handle and the base members to provide points of support for the container. A containment loop encompasses the neck portion of the frame and inwardly urges the points of support against the container as it is pushed into position within the containment loop. The base members are capable of being pressed into a planar assembly when the container is removed to allow a plurality of similarly constructed frames to be compactly stacked.
