Apparatus for dispensing volatile materials.

摘要

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.
