Abstract
An aromatic package comprises a liquid or gel type aromatic and a sack made of a gas-permeable but liquid-impermeable film and hermetically receiving the aromatic. In another form of the aromatic package of the invention, the above-mentioned aromatic package is received in a gas-permeable case which in turn is hermetically sealed in a gas-impermeable packaging member. In use, the packaging member is broken and the case is placed in, for example, a house room or compartment of a motor vehicle, so that the fragrance or aroma is released and floats on the air.
