A spill proof reservoir is provided for the release of vapours e.g. pheromones, said reservoir having an enclosure (10) and a tubular member (20) extending from a wall of the enclosure to its center. The tubular member (20) is open to the atmosphere and it has a means (26) of communicating with the inside of the reservoir at its end located at the center of the enclosure. The reservoir is only filled to half of its capacity so that regardless of its orientation, the communications means (26) of the tubular member is never below the surface of the liquid. The vapours of the liquid contained within the enclosure (10) are released via the communicating means (26) and the tubular member (20). <IMAGE> |
