Description

[0045] Further features and advantages of the invention will become apparent from the description hereinafter of a preferred embodiment and from the following drawings, to which reference is made. In the drawing:

[0046] FIG. 1 shows a schematic diagram of the inventive packaging system according to a first embodiment.

[0047] Plastic container 10, illustrated in FIG. 1, of the inventive packaging system 12 is formed as a foldable stand-up film bag with a closable opening 14. In the embodiment shown here, opening 14 is closed with a screw cap 16, to which a stopcock 18 is attached. Plastic container 10 further has a handle 20 molded in one piece onto plastic container 10.

[0048] Powdered reactive component 22 of a curable inorganic multi-component mass is filled into plastic container 10. Furthermore, large-grained mixing elements 24 in the form of stones or gravel are distributed in powdered component 22. An air volume 26, which amounts to approximately 40% of the total volume of plastic container 10, is present above powdered component 22.

[0049] The stones used as mixing elements 24 have a maximum diameter of 10 mm to 40 mm and/or a weight of 2 g to 20 g.

[0050] Metal ball bearings or glass marbles, preferably with a diameter of 8 mm to 30 mm and/or a weight of 2 to 20 g may also be used as mixing elements 24.

[0051] Instead of stopcock 18, a cartridge nozzle attached to screw cap 16 may be provided, or screw cap 16 may have a port for an extension hose.

[0052] Powder component 22 preferably comprises a hydraulically binding binder based on gypsum or cement mortar, as well as, optionally, the solid components of a foaming system, such as an alkali metal or alkaline earth carbonate and/or a catalyst for release of oxygen from an oxygen carrier. The grain size distribution of powdered component 22 is preferably d90200 m, i.e. approximately 90% of all particles of the powdered component have a grain size of 200 m or smaller. The powdered component may also contain fibers with a length of approximately 1 to 6 mm and a fiber diameter of 10 to 30 m.

[0053] Liquid hardener component 28 provided for mixing with powdered component 22 may be supplied in a separate package 30. Hardener component 28 preferably comprises water as well as, optionally, the liquid or dissolved components of a foaming system, such as an acid and/or hydrogen peroxide.

[0054] The curable multi-component mass is preferably supplied as a foam-in-place foam, which is used as an inorganic fire-protection foam or insulating foam.

[0055] To produce the curable multi-component mass, screw cap 16 is opened and liquid hardener component 28 is added to powdered component 22 in plastic container 10. During production of a foam-forming mass, part of air volume 26 may be removed from plastic container 10 by folding plastic container 10 together. Then plastic container 10 is closed once again with screw cap 16. Solid inorganic powdered component 22 is mixed with liquid hardener component 28 by shaking and/or agitating and/or kneading, with formation of the curable multi-component mass. During shaking, plastic container 10 may be held by handle 20. Any overpressure developed by foaming of the mass may also be relieved by opening stopcock 18.

[0056] After powdered and liquid components 22, 28 have been mixed, screw cap 16 is opened and a cartridge nozzle is mounted on screw cap 16. By folding plastic container 10 together, the foamed multi-component mass is discharged from plastic container 10 via the cartridge nozzle and introduced directly into the opening to be filled in the building. There the multi-component mass may be subsequently shaped, further foamed and cured.
