Sample for dispensing liquid product such as perfume comprises elastic means increasing volume of reservoir when removable closure is removed

摘要

Sample is made of two sheets (1, 2) welded together around periphery (11, 12) defining reservoir (3) for fluid product. Reservoir has elastic means (4) increasing volume of reservoir, dispensing orifice (50) through which fluid product is dispensed mixed with air to produce two-phase spray, and removable closure (12) to close dispensing orifice thus insulating reservoir from outside. When closure is removed, air enters reservoir through dispensing orifice so that elastic means can expand, increasing inner volume of reservoir.
