US 4,717,017 A · Package with means for releasing aromatic substance on opening

Abstract

A package, such as a cigarette pack, is provided with a receptacle for containing a fragrance or flavor to be released upon initial opening by the consumer. The receptacle is provided by attaching to the polymeric film circumscribing the sealed package, in the area overlying the tear tape, an additional layer of polymeric film. The fragrance or flavor is entrapped between the polymeric film and the extra polymeric layer and is released when the tear tape is pulled through the receptacle to unseal the pack. The receptacle can be provided with compartments to minimize leakage or to allow the flavor or fragrance to be kept in two or more relatively inert components which react on contact to form the fragrance or flavor or, possibly, to form a propellant to disperse the fragrance or flavor.
