    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

    [0040] FIG. 1 shows a first example of the container as per the invention in the form of a tube 1. The tube 1 comprises, in a known fashion, a base body with a flexible external edge 2 that is made, for example, of a plastic that can undergo a reversible change in shape. A connecting segment 3 that essentially has a hollow cylindrical shape and is comprised of a rigid material with bending resistance, in particular a plastic material, is located at the front end of the tube 1. An external thread 4 is located on the outer surface. A tube squeezer 5 is located at the rear end of the tube 1.

    [0041] As per the invention, the interior of the tube 1 is divided up into two inner chambers 6, 7. FIG. 2 shows a first embodiment in which the two inner chambers 6, 7 are arranged next to one another. FIG. 3 shows a second embodiment with two coaxial inner chambers 6, 7, meaning that a first inner chamber 6 surrounds a second, central inner chamber 7.

    [0042] The inner chambers 6, 7 run parallel to one another in the longitudinal direction of the tube 1 in both embodiments. The inner chambers 6, 7 are completely separated from one another via walls 8 here. Each inner chamber 6, 7 extends over the entire length; especially the inner chambers 6, 7 in the area of the connecting segment 3 form outlet areas 6a, 7a that are separated by the walls 8. Different materials are thereby stored with complete separation from one another in the inner chambers 6, 7 with their outlet areas 6a, 7a.

    [0043] As per the invention, an aerobic adhesive is stored in the first inner chamber 6. A hydrophilic activator is stored in the second inner chamber 7.

    [0044] The aerobic adhesive is made up of a silane polymer or polyurethane. The aerobic adhesive is available in an uncured form in the first inner chamber 6 and therefore in a flowable form.

    [0045] A hydrophilic activator that comprises a reaction accelerator in general that accelerates the curing of the aerobic adhesive when the hydrophilic activator is mixed together with the aerobic adhesive is stored in the second inner chamber 7.

    [0046] The hydrophilic activator is available in a gel-like and therefore a flowable form in the second inner chamber 7. The hydrophilic activator is advantageously comprised of cotton, cellulose, a fiber composite material, a salt, a mineral, a resin, glycerin or propylene glycol.

    [0047] Moisture, especially water or isopropanol, is added to the hydrophilic activator, in particular in the case that the substances of the hydrophilic activator originally exist in a solid form, so the hydrophilic activator exists in a gel-like form.

    [0048] A mixing unit is placed on the connecting segment 3 to provide a fastening agent by means of which two objects can be joined via a glue bond in a permanent and firm manner. FIG. 4 shows a mixing unit of that type in the form of a static mixer 9.

    [0049] The static mixer 9 is comprised of a mixing tube 10 and a mixing spiral 11 that is mounted in the mixing tube 10 and that extends in its longitudinal direction. In the present case, the mixing spiral 11 has four spiral segments that are connected to one another in the axial direction. In general a different, in particular larger, number of spiral segments can also be provided. A thread 12 that can be screwed onto the external thread 4 of the connecting segment of the container, causing a reversible and detachable connection to arise between the container and the static mixer 9, is located at the rear end of the static mixer 9. The front end of the static mixer 9 is designed in the form of a tip; an outlet opening 13 is provided at its front end.

    [0050] To provide the fastening agent, the tube squeezer 5 is turned, meaning in general that the supply device is actuated, causing a pressure to be exerted starting from the rear end of the tube 1 on both the aerobic adhesive in the first inner chamber 6 and on the hydrophilic activator in the second inner chamber 7. Both the aerobic adhesive and the hydrophilic activator are fed to the static mixer 9 from the two inner chambers 6, 7 because of this pressure. The design of the supply device in the form of the tube squeezer 5 that exerts a uniform pressure on the aerobic adhesive in the first inner chamber 6 and on the hydrophilic activator in the second inner chamber 7 and the specific geometric design of the inner chambers 6, 7 ensure that the aerobic adhesive and the hydrophilic adhesive are fed to the static mixer 9 in a defined, constant mixing ratio.

    [0051] The aerobic adhesive and the hydrophilic activator are brought, as a result of the pressure exerted by the tube squeezer 5, one after the other through the individual spiral segments of the mixing spiral 11 in the static mixer 9. There is always a stronger and stronger mixing of the two components from one spiral segment to the next. The number of spiral segments is chosen in such a way that the aerobic adhesive and the hydrophilic activator are completely mixed together at the end of the mixing spiral 11. The fastening agent that is formed in this way is then discharged from the static mixer 9 through the outlet opening 13 and can then be used to attach two objects.

    [0052] After use of the static mixer 9, it is unscrewed from the container again. A new static mixer 9 is screwed onto the connecting segment of the container as soon as the container is required from anew to provide the fastening agent.

    [0053] FIG. 5 shows a second example of the container in the form of a cartridge 14. The cartridge 14 has, analogous to the embodiment of FIG. 2, two concentric inner chambers 6, 7 separated by a wall 8. In principle, inner chambers 6, 7 lying next to one another can also be provided.

    [0054] Analogous to the embodiment of FIG. 1, a connecting segment 3 with an external thread 4 is provided at the front end of the cartridge 14. The inner chambers 6, 7 extend over the entire length of the cartridge 14 and are routed with their outlet areas 6a, 7a into the interior of the connecting segment 3.

    [0055] Pistons 15a, 15b, as supply devices, are located at the rear end of the cartridge 14. Pressure is exerted on the aerobic adhesive stored in the first inner chamber 6 with the first piston 15a via an actuation device that is not shown. Correspondingly, pressure is exerted on the hydrophilic activator stored in the inner chamber 7 with the second piston 15b. The same pressure is preferably exerted on the two components. The aerobic adhesive and the hydrophilic activator correspond in terms of their design to the embodiment in accordance with FIG. 1.

    [0056] In a further analogy to the embodiment in accordance with FIG. 1, the static mixer 9 according to FIG. 5 can be screwed onto the connecting segment 3 of the cartridge 14. The aerobic adhesive from the first inner chamber 6 and the hydrophilic activator from the second inner chamber 7 are then fed into the static mixer 9, where the mixture of these components takes place, via the exertion of pressure with the pistons 15a, 15b. The fastening agent that is formed in this way is discharged again from the outlet opening 13 of the static mixer 9.
