A dispenser with a lid laminate providing controlled release of a volatile material contained in a tray is disclosed. The lid includes a vapor impermeable, removable outer laminate and a vapor permeable inner layer covering an open side of the tray. The outer laminate includes layers of polyethylene terephthalate (PET) and aluminum foil removably adhered to the inner layer of biaxially-oriented polypropylene (OPP) by an ethylene acrylic acid copolymer. Bottom and side walls of the tray are constructed of a metal/polymer pressure-formed colored tray laminate impermeable to the vapors and volatile material. The tray has a peripheral lip with an outer surface of cast polypropylene to which the vapor permeable inner layer of the lid is heat sealed.

Aromatic liquids substances such as deodorizers, room freshener compositions, perfumes, fragrances and the like are dispensed in vapor phase from a container holding the substance in liquid phase. In the best mode, the container is in conical form, having a controlled opening or openings through which the liquid volatile substance is dripped downwardly onto a conical substrate, from which it is dispensed in vapor phase into the atmosphere. The dispenser is configured such that it may stand, as on a counter or any flat surface, or may be hung, as in a closet, in an automobile, or the like.
