Abstract

A dispenser for substances includes an outer shell with a deformable outer wall which encloses the deformable container arrangement and at least one balancing valve for balancing air, wherein an air filled intermediary gap is located between the outer wall and the container arrangement and the dispenser is configured to dispense substances after pressure loading the outer shell, wherein the container arrangement includes at least two containers and a common dispensing head are connected with each other pressure tight in at least one portion, and wherein at least one of the containers includes self-closing filling valves which are configured to be openable by pressure during filling the at least two containers.

11. The dispenser according to claim 10 , further comprising:

a gravity actuated sealing ball supported in a cage.

12. The dispenser according to claim 1 , wherein the balancing valve is configured to be pressure loaded with compressed air for bleeding the containers of the liquid or pasty substances.

13. The dispenser according to claim 1 , wherein the outer shell comprises an oval cross section configuration.

14. The dispenser according to claim 1 , wherein the dispenser includes a cover.

15. The dispenser according to claim 14 , wherein the cover is configured to close an outlet opening sealed tight, and wherein the outlet opening is adjacent to a mixing element.
