<p>A container for volatile essences comprising a vapour-impermeable outer layer (2), in which a pair of substantially similar half-shells are heat-moulded, separated symmetrically by an edge line (6) along which the outer layer (2) is folded to position the half-shells one against the other; an intermediate layer (5), comprising a vapour-permeable material, is inserted between the half-shells and heat-sealed along an outer frame (3) of each half-shell so as to maintain the container (1) in a closed position and form a pair of opposite chambers (7) which are filled with volatile material; the container (1) is opened like a book by parting of the intermediate layer (5) and stands alone in an upright position. <IMAGE></p> |
