The present invention relates to filters for coffee, tea, hot chocolate etc., in which a filter is placed in a cylindrical container and whatever is to be filtered is placed in the filter that has been placed in the cylindrical container. Thereafter, either hot or ice cold water, in the case of iced tea, is poured into the cylindrical container over that which is to be filtered. In more cases than not, the filter collapses, especially in the case of coffee and tea, the result is that coffee grinds and tea leaves eventually get into the coffee cup or tea leaves get into the tea cup. The present invention solves this problem by providing a retention ring of shape retaining inert material, such as plastic or stainless steel that is capable of being compressed in size placing it inside the filter that has been placed in the cylindrical container that is to be filled with a product. The retention ring, when released from compression, returns to its original shape and holds the filter tight against the walls of the cylindrical container, thereby eliminating the contamination in the user's cup.

[ What I claim is:] [1.] An open ended filter shape retention ring having opposing free ends thereof spaced from each other comprising: a narrow strip shaped compressible open ring capable of returning to its original shape, and said narrow strip shaped compressible open ring having a main ring section and opposed end sections, each opposed end section being bifurcated to form a first portion which defines a cantilevered, inwardly directed, continuously curved finger hold which curves back toward the main ring section and has a terminal end spaced from said main ring section, and a second portion which extends in the normal curvature of the main ring section, each second portion having a terminal end which defines said opposing free ends which have an opening there between when said ring is in its original shape, whereby said ring free ends upon compression of said finger holds passing each other in opposite directions to reduce the diameter of said ring.
