摘要

The flat foil container for the preservation and evaporation of minute quantities of scents, is for use in toys, playing cards or calenders. It consists of two gas-tight foils e.g. lacquered aluminium foil, which enclose a smaller circular disc of filter paper, impregnated with a drop of oil essence or scent. The top foil has a small circular cut-out but is first covered by an adhesive disc which is torn off before application.
