ABSTRACT:
A spraying device comprises an outer compressible container and an inner compressible container. The outer container the interior of which having no communication with the surrounding atmosphere contains a preferably liquid active substance whereas the inner container initially contains air. The inner container communicates with the atmosphere via a narrow channel whereas the inner container is made permeable such that active substance may reach the inner container in small quantities. Squeezing of the outer container will thus generate a spray comprising air and active substance. The device may further have openings to enable air to be suck into the inner container after each use of the device.
