发明名称 ARTICLE FOR DISPENSING VOLATILE SUBSTANCES
摘要 <p>An article for the slow release of volatilizable substances, such as deodorizers, insecticides, repellants and the like, the article being formed from opposed outer and inner wall members joined along their peripheral portions to define a central reservoir portion for receiving and confining a volatile substance. The inner and outer wall member comprises a liquid non-porous but gas permeable flexible polymeric sheet material having an impermeable barrier layer releasably bonded to the outer surfaces thereof. In one embodiment the article is formed from a single strip folded and bonded to itself to form the reservoir. The barrier layer prevents escape of volatilized substance until its removal at the time of desired use. In a further aspect, a strippable adhesive layer is bonded to the outer surface of the second gas impermeable layer and removal of the strippable layer enables adhesive bonding of the article to environmental surfaces.</p>
