Abstract: The invention relates to an aerosol can comprising a body containing a propellant and an aerosol product, a valve whose actuation enables said aerosol product to be sprayed, and a spray head (1) which serves to discharge the aerosol product to the environment when the valve is actuated. The spray product discharge rate of the inventive aerosol can is adjustable by means of an adjusting device provided in the spray head (1). Said invention can primarily be used for aerosol paint cans in view of the fact that for such applications a controlled and uniform discharge rate is of particular importance in order to avoid painting defects.

Abstract: Pressurized can comprising a body (2), a dome (3) accommodating a valve (4), a concavely shaped bottom (5), an inner casing (7) attached to a cup (6), a push rod (9) arranged in the inner casing (7), said push rod (9) being actuated through the cup (6) and intended to force open the inner casing (7), with said inner casing (7) being joined to the cup (6) via a spring cage (11), said spring cage (11) containing a spring-loaded trigger (12) which acts on the push rod (9) which, in turn, acts on a cover (8) arranged at the can-side end of the inner casing (7), said cover (8) being a membrane which seals the inner casing (7) at its can-side end hermetically against the contents of the pressurized can (1) and which is torn open by the push rod (9) when the trigger (12) is actuated.

Abstract: The invention relates to a pressure pack aerosol can comprised of a body blank (2), of a dome (3) for accommodating a valve (4), of an inwardly arched bottom (5), of an inner sleeve (7), which is arranged on a disk (6), and of a tappet (9), which is arranged inside the inner sleeve (7), which is provided for splitting open said inner sleeve (7) and which can be displaced therethrough by the disk (6). According to the invention, the inner sleeve (7) is joined to the disk (6) via a spring cage (11), and the spring cage (11) contains a release mechanism (12), which is spring-mounted and which acts upon the tappet (9). Said tappet (9), in turn, acts upon a cover (8), which is arranged on the can-side end of the inner sleeve (7), and splits the cover open when actuated. A diaphragm (15) is arranged between the tappet (9) and the release mechanism (12) and hermetically seals the inner sleeve (7), on its disk-side end, off from the contents of the pressure pack aerosol can (1).

Abstract: An aerosol preparation for two-component paint spray cans, in which the paint material consists of acrylic resins containing OH-groups, and the hardener consists of aliphatic polyisocyanatea. The paint material and hardener are filled in different containers within a spray can and united only immediately before they are processed, and jointly sprayed from the spray can via a propellant consisting of a propane/butane mixture. The weight ratio of diluted paint material to propellant amounts to about 75:25 to 70:30. The paint material consists of OH-group-containing high-solid acrylic resins with a higher solids content and with a mean molecular weight of <5000, and having no styrene and an OH-number of <150.

Abstract: A spray can, particularly for paints and paint preparation materials, is pressurized with a propellant, particularly propellant gas, as a result of which the paint material can be sprayed when a valve is opened. In order to substantially increase the paint output amount per unit time so that a greater layer thickness is achieved in the same working time, the propellant provided in the spray generates a pressure of 4.5 to 6 bar, the output amount of the paint material is 15 g to 35 g per 10 seconds for uninterrupted flow, and that the paint is output in the form of broad-stream atomization.
