MULTI-USE DISPENSING DEVICE

摘要

A dispenser consisting of an opened celled housing or vessel forming a chamber of predetermined size permeable to the ingress and egress of fluids more particularly volatile gases to permit escape or dispensing of such gases or other fluids from the chamber into a desired environment. At a critical temperature a means is mounted in or on the vessel for loading and holding of materials to be dissolved or volatilized at the critical temperature and for passing the dissolved substance or the resultant gas to the chamber for dispensing or escape through the permeable walls of the vessel. The material to be dissolved or volatilized will as a general rule be held in a carrier or like device which will degrade or act to release the material to be dissolved or volatilized.
