Abstract:
1. An apparatus for preventing freezing at an outlet of a fire extinguisher, said apparatus comprising: a fire extinguisher bottle; and a container in the bottle having walls with a plurality of openings therein sized to confine a drying agent in the container but to permit fire extinguisher fluid to enter through the openings into the container, said container being open to the interior of the bottle so that as soon as fire extinguisher fluid is introduced into the bottle, the fluid comes into contact with the drying agent and contacts the drying agent substantially continuously, wherein said container when positioned in said bottle remains unattached to the container so as to be readily removable and said container includes flexible structure attached to the container that spaces the container from interior walls of the bottle and restricts movement of the container within the bottle when the bottle is subjected to movement.
