FIELD: aerosol containers. SUBSTANCE: proposed barrierless vessel for storage and discharge of compressed and/or liquefied gas and liquid materials and adapted for holding propellant and liquid material in contact has cylindrical shape and it is provided with discharge valve with valve hole to let out preset amount of material and propellant at preset velocity in form of aerosol spray. Vessel preserves pressure of propellant sufficient to discharge material in vessel completely. Said vessel preserves sufficient rigidly under pressure to prevent easy deformation when being pressed on by finger or cramped by hand. Vessel is provided with side wall whose thickness permits easy deflection under pressure of finger or easy cramping by hand. Thickness of side wall is chosen to provide rigidity of vessel at application of inner pressure in vessel, said pressure being chosen to preclude distortion of vessel shape at finger pressure or hand cramping effort. Thanks to it, vessel can be made with more thin walls. EFFECT: reduced metal usage, provision of environmental protection. 7 cl, 4 dwg
