2. The system according to claim 1, additionally comprising a pressurizer of the first and second container selected from the group consisting of one or more of a pressurized air conduit, a compressor, and a pressurized air cylinder.

3. The system according to claim 1, wherein the containers are formed of a material having a density of less than 1.4 kg/dm.sup.3, and wherein the containers have a volume of 10-100 dm.sup.3.

4. The system according to claim 1, wherein a material of the inner flexible vessel is made of an inert material, preferably chosen from polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), and wherein the outer wall is made of a polymer material.

5. The system according to claim 1, wherein a material of the inner flexible vessel further comprises a reflecting material.

6. The system according to claim 1, wherein the inner vessel is provided with an outlet and a connector for connecting a tube.

7. The system according to claim 1, wherein a space between the inner vessel and outer wall is designed to pressurize the inner vessel.

8. The system according to claim 1, wherein the first adhesive component is selected from the group consisting of a poly-chloroprene dispersion, polyurethane dispersion, polyacrylate dispersion, vinylacetate-ethylene dispersion, ethylene-vinylacetate dispersion, natural rubber dispersion, styrene-butadiene-styrene copolymer dispersion, and styrene-butadiene rubber dispersion, and wherein the second adhesive component is a coagulant.

9. The system according to claim 1, further comprising wherein the spray gun a 2K spray gun or an airless spray gun.

10. The system according to claim 1, further comprising one or more of a connector, a handle, and a tube providing pressure.

11. The system according to claim 1, further comprising a coupler, the coupler comprising one or more of the group consisting of a connector, a pressure regulator, a pressure monitor, a valve, a handle, a tube providing pressure, the tube providing the first adhesive component to the spray gun, and the tube providing the second adhesive component to the spray gun.

12. The system according to claim 11, wherein the coupler comprises one or more of the group consisting of a stainless steel ball valve, a nozzle, a reducing ring, a first nipple, an air regulator, a manometer, a second nipple, a tee, a push in fitting, a hose clamp, a push in adaptor, and a push in fitting.

SUMMARY OF FIGURES

(1) FIGS. 1-3 show couplers.

(2) FIG. 4 shows a container.

(3) FIG. 5 shows a system 200.

DETAILED DESCRIPTION OF FIGURES

(4) In FIGS. 1-3 a coupler is shown. Therein the following items are shown: 1 Coupler BSP 2 Stainless steel ball valve 10.0 male female 3 Nozzle SS for tube 10 mm+wing nut BSP 4 Reducing ring BSP 5 Nipple BSP 6 Air regulator -04 7 Manometer 0-4 bar 40 8 Nipple BN 9 Tee SSt 316 10 Push in fitting 8 mm 11 Hoseclamp 11-17 mm ABA 12 Push in adaptor BSP 5/16 tube OD 13 Push in fitting

(5) FIG. 4 shows a container 100. Therein an outer wall 52 and an inner flexible vessel 51 for shielding the component from air and for pressurizing the component are shown. In between the outer wall and inner flexible vessel pressure can be provided, e.g., by air 53. In the figure the inner vessel comprises a component. The inner vessel is partly emptied in the figure.

(6) FIG. 5 shows a system 200. Therein two containers 100a and 100b are provided, having a first and second adhesive component respectively. The containers are provided with pressure 53, such as by 200 kPa air pressure. As a result components flow through tubes 57a and 57b, respectively, attached by a coupler to the container, towards a spray equipment 80. The spray equipment may be a hand-held equipment. The adhesive may then be applied.

(7) The invention although described in detailed explanatory context may be best understood in conjunction with the accompanying figures.

(8) It should be appreciated that for commercial application it may be preferable to use one or more variations of the present system, which would similar be to the ones disclosed in the present application and are within the spirit of the invention.
