A discharge head for a dispenser including a securing element coupling the discharge head to the dispenser, a housing having an outlet opening, and a valve body. The valve body closes the outlet opening when the pressure of a medium in the discharge head is below a threshold value, and in a ready-for-use state the valve body releases the outlet opening when the pressure of the medium in the discharge head is above the threshold value. The valve body is mounted over a travel path for releasing and closing the outlet opening, and a locking handle moves in relation to the securing element in order to transfer the discharge head into a locked state in which the travel path of the valve body is reduced to zero, and/or in order to transfer the discharge head from the locked state into the ready-for-use state.

1. A discharge head for a dispenser, comprising a securing element for coupling the discharge head to the dispenser, a housing having an outlet opening and a valve body, wherein the valve body closes the outlet opening when the pressure of a medium in the discharge head is below a threshold value, and, in a ready-for-use state, the valve body releases the outlet opening when the pressure of the medium in the discharge head is above the threshold value, and wherein the valve body, in the ready-for-use state, is displaceable along an adjustment path for releasing and closing the outlet opening, wherein a locking handle is provided which is movable relative to the securing element, in order to transfer the discharge head to a locked state in which the adjustment path of the valve body is reduced to zero, and/or in order to transfer the discharge head from the locked state to the ready-for-use state, andthe housing is coupled to the securing element so as to be rotationally fixed and movable in the direction of the adjustment path, wherein the adjustment path of the valve body is dependent on a distance between the housing and the securing element. 2. The discharge head as claimed in claim 1, wherein the valve body is kinematically decoupled from the locking handle, such that a movement of the locking handle relative to the securing element is not transmitted to the valve body. 3. The discharge head as claimed in claim 1, wherein the locking handle is mounted on the securing element in such a way as to be rotatable about an axis extending parallel to the adjustment path. 4. The discharge head as claimed in claim 3, wherein the housing is kinematically coupled to the locking handle, wherein a twisting of the locking handle relative to the securing element causes a movement of the housing relative to the securing element in the direction of the adjustment path. 5. The discharge head as claimed in claim 4, wherein the housing has a first sleeve-shaped connecting portion, and the locking handle has a second sleeve-shaped connecting portion which is arranged rotatably in or on the first sleeve-shaped connecting portion, wherein the first sleeve-shaped connecting portion and the second sleeve-shaped connecting portion have mutually facing surfaces, one of the surfaces including at least one control curve and the other of the surfaces including a control cam interacting with the control curve. 6. The discharge head as claimed in claim 1, wherein the valve body is arranged on a bearing element and, via the bearing element, is mounted movably between the housing and the securing element along the adjustment path. 7. The discharge head as claimed in claim 6, wherein the bearing element has a compensating element, via which the valve body is mounted movably between the housing and the securing element along the adjustment path. 8. The discharge head as claimed in claim 7, wherein the bearing element has a sleeve which can be mounted in a fixed position on the securing element, wherein the valve body is coupled movably to the sleeve along the adjustment path via the compensating element. 9. The discharge head as claimed in claim 6, wherein the bearing element has a piston that takes up forces for an adjustment movement of the valve body. 10. The discharge head as claimed in claim 8, wherein the bearing element has a securing ring secured on the housing, which securing ring is spaced apart from the sleeve in the direction of the adjustment path and is arranged coaxially with respect to the sleeve. 11. The discharge head as claimed in claim 1, wherein the housing has a pressure chamber adjacent to the outlet opening. 12. The discharge head as claimed in claim 1, wherein a resetting element is provided which forces the valve body to the closure position. 13. A dispenser with a deformable wall and with a discharge head, comprising a securing element for coupling the discharge head to the dispenser, a housing having an outlet opening and a valve body, wherein the valve body closes the outlet opening when the pressure of a medium in the discharge head is below a threshold value, and, in a ready-for-use state, the valve body releases the outlet opening when the pressure of the medium in the discharge head is above the threshold value, wherein the valve body, in the ready-for-use state, is displaceable along an adjustment path for releasing and closing the outlet opening, and wherein a locking handle is provided which is movable relative to the securing element, in order to transfer the discharge head to a locked state in which the adjustment path of the valve body is reduced to zero, and/or in order to transfer the discharge head from the locked state to the ready-for-use state, and the housing is coupled to the securing element so as to be rotationally fixed and movable in the direction of the adjustment path, the adjustment path of the valve body being dependent on a distance between the housing and the securing element. 14. The dispenser as claimed in claim 13, wherein the securing element is mounted in a rotationally fixed manner on the dispenser. 15. The discharge head as claimed in claim 1, wherein the locking handle is mounted on the securing element for rotation about a longitudinal axis of the discharge head.
