Claim:
A device for spraying a liquid, wherein the liquid is contained in a container that, in an initial state, is a unitary closed container comprising a head to be broken off or sawed off for providing a removal opening, the device comprising: a pump spraying device that operates by a pumping action and is adapted to be arranged on the removal opening of the container; the pump spraying device comprising a spraying unit with a spray head and a connecting adapter, wherein the connecting adapter is fixedly connected to the spraying unit and wherein the pumping action of the pump spraying device transports the liquid from the container to the spray head; wherein the connecting adapter has a remote end remote from the spray head and has an annular seal that is connected to an end face of the remote end and is adapted to rest sealingly against a shoulder of the container about the removal opening; wherein the connecting adapter is essentially cylindrical; a sleeve having an upper open end and a lower end, wherein the lower end of the sleeve has a bottom and wherein the sleeve is adapted to receive the container through the upper open end; wherein an outer diameter of the connecting adapter is matched substantially to an inner diameter of the sleeve; wherein the sleeve and the connecting adapter are separate parts and wherein the sleeve is detachably connected with the upper open end to the connecting adapter by pushing the sleeve onto the connecting adapter in an axial direction of the connecting adapter such that the connecting adapter is received in the sleeve; wherein the sleeve is axially slidable relative to the connecting adapter; wherein the sleeve has inner locking ribs and the connecting adapter has outer locking elements matching the locking ribs, wherein the sleeve is slidable in the axial direction and adjustable relative to the connecting adapter in different relative axial positions for accommodating containers of different length, wherein the different relative axial positions are secured by the locking ribs and the locking elements.
