Abstract

An expandable and collapsible device for cleaning the internal surfaces of containers, such as glass coffee containers of the type used with coffee makers, is disclosed. The device includes a plurality of resilient strip elements shaped and arranged with respect to each other such that the upper sections define a generally cylindrical pattern while the lower sections define a bubble-like pattern. The strip elements are capable of being collapsed or compressed sufficiently to permit entry into a container. Also, the strip elements are expandable when a downwardly directed force is applied, such that the lower portions of the elements engage the bottom, lower section, and neck portion of the container. Means are provided for applying an upwardly directed force to the strip elements such that the lower sections of the elements will expand radially outwardly and upwardly to engage the upper section of the containers. Locking means are also provided for locking the elements in a desired expanded orientation permitting the device to be rotated to clean the interior surfaces of the container. Any desired type of scouring or wiping material may be secured to the lower sections of the strip elements.
