<p>A spray container or aerosol 1 has a spray valve 2 and, internally, is provided with a butyl rubber sleeve 4 surrounding a textile mesh sleeve 7 and a core 5. When an outer chamber 6 is filled with a liquid to a level 17, that liquid is progressively transferred to an inner chamber (inside the sleeve 4) by capillary action through the sleeve 7 with expansion of the sleeve 4 (see Fig. 2) against the resilient opposition of the latter. Upon operation of the spray valve 2, the expanded sleeve 4 will contract and eject the liquid which it contains. The container 1 is refillable and no propellant gas is required. An inner sleeve 8 can be located between the core 5 and the textile sleeve 7, and the bottom of the core 5 and sleeve 8 are so constructed as to facilitate the ascent of the liquid. <IMAGE></p> |
