Abstract

A discharging device for discharging liquids includes an outer housing encompassing an inner chamber, a liquid storage receptacle, a discharge orifice, a delivery device for delivering liquid from the storage receptacle to the discharge orifice, a cap that covers the discharge orifice when present on the outer housing in a safety position, and a manual actuator adapted to actuate the delivery device and which is movable relative to the outer housing between a neutral relative position and an actuated relative position. The cap and the manual actuator cooperate so that displacement of the manual actuator is mechanically blocked when the cap is in its safety position. A locking element that is movable in relation to the outer housing is constrainedly coupled with the movement of the manual actuator and extends in the actuated position through a hole in the outer housing to a region that the cap blocks when mounted in its safety position.

First claim

The invention claimed is:

1. A discharging device for discharging liquids, comprising:
an outer housing encompassing an inner chamber;
a liquid storage receptacle;
a discharge orifice;
a delivery device for delivering liquid from said liquid storage receptacle to said discharge orifice;
a cap that covers the discharge orifice when present on said outer housing in a safety position;
a manual actuator, which is adapted to actuate said delivery device and which can be moved relative to said outer housing between a neutral relative position and an actuated relative position, said cap and said manual actuator cooperating in such a manner that displacement of the manual actuator is mechanically blocked when said cap is in the safety position; and
a plurality of locking extensions on said cap and extending in a pull-off direction of said cap, each of the locking extensions extending, in the safety position of said cap, through a hole in the outer housing for effecting blockage of said manual actuator in the inner chamber, and said locking extension and said hole being mutually configured in such that total removal of said cap from said outer housing in the pull-off direction starting from the safety position is only possible when said cap has beforehand been moved relative to said outer housing in an orthogonal plane oriented orthogonally to said pull-off direction from a locked state corresponding to said safety position to a released state;
wherein each of the locking extensions fit in the hole such that rotation of said cap about an axis parallel to the pull-off direction causes displacement of all of said locking extensions from the locked state to the released state in relation to said holes.

2. The discharging device according to claim 1 , wherein:
each of said locking extensions has a main portion, which in the locked state of said cap is in alignment with said hole, as regarded in the pull-off direction, and
an undercut portion is provided on each of said locking extensions, which is not in alignment with said hole in the locked state of said cap, as regarded in the pull-off direction.

3. The discharging device according to claim 2 , wherein a force applying element is provided, which exerts a counter-force on said cap counteracting the displacement of said cap from the locked state to the released state.

4. The discharging device according to claim 3 , wherein said force applying element is provided in the form of a resiliently deflectable fin on said cap or on each of said locking extensions of said cap, which fin, when said cap is moved from the locked state to the released state, is resiliently deflected by a counterpart that is immovable in relation to said outer housing.

5. The discharging device according to claim 2 , wherein said cap and said outer housing are mutually configured in such a way that the displacement of said cap from the locked state to the released state is only possible when said cap has first been moved from the safety position in the pull-off direction.

6. The discharging device according to claim 1 , wherein a force applying element is provided, which exerts a counter-force on said cap counteracting the displacement of said cap from the locked state to the released state.

7. The discharging device according to claim 6 , wherein said force applying element is provided in the form of a resiliently deflectable fin on said cap or on each of said locking extensions of said cap, which fin, when said cap is moved from the locked state to the released state, is resiliently deflected by a counterpart that is immovable in relation to said outer housing.

8. The discharging device according to claim 7 , wherein the plurality of locking extensions comprises a first locking extension and a second locking extension, the first locking extension including a first vertical portion and a first horizontal portion cantilevered from the first vertical portion adjacent a first bottom end of the first vertical portion and extending laterally in a first direction perpendicular to the pull-off direction, the second locking extension including a second vertical portion and a second horizontal portion cantilevered from the second vertical portion adjacent a second bottom end of the second vertical portion and extending laterally in a second direction perpendicular to the pull-off direction, and rotation of said cap about the axis moves the first vertical portion of the first locking extension out away from a first stop and the second vertical portion of the second locking extension out away from a second stop, the first direction being opposite to the second direction, with the first vertical portion of the first locking extension and the second vertical portion of the second locking extension extending laterally such that the first vertical portion of the first locking extension and the second vertical portion of the second locking extension do not extend inward toward the axis or outward away from the axis such that rotation of the cap allows the first vertical portion of the first locking extension to move out from under the first stop and the second vertical portion of the second locking extension to move out from under the second stop.

9. The discharging device according to claim 6 , wherein said cap and said outer housing are mutually configured in such a way that the displacement of said cap from the locked state to the released state is only possible when said cap has first been moved from the safety position in the pull-off direction.

10. The discharging device according to claim 7 , wherein said cap and said outer housing are mutually configured in such a way that the displacement of said cap from the locked state to the released state is only possible when said cap has first been moved from the safety position in the pull-off direction.

11. The discharging device according to claim 1 , wherein said cap and said outer housing are mutually configured in such a way that the displacement of said cap from the locked state to the released state is only possible when said cap has first been moved from the safety position in the pull-off direction.

12. A discharging device for discharging liquids, comprising:
an outer housing encompassing an inner chamber;
a liquid storage receptacle;
a discharge orifice;
a delivery device for delivering liquid from said liquid storage receptacle to said discharge orifice;
a cap that covers the discharge orifice when present on said outer housing in a safety position;
a manual actuator, which is adapted to actuate said delivery device and which can be moved relative to said outer housing between a neutral relative position and an actuated relative position, said cap and said manual actuator cooperating in such a manner that displacement of the manual actuator is mechanically blocked when said cap is in the safety position; and
a plurality of locking extensions on said cap and extending in a pull-off direction of said cap, each of the locking extensions extending, in the safety position of said cap, through a hole in the outer housing for effecting blockage of said manual actuator in the inner chamber;
wherein the plurality of locking extensions comprises a first locking extension and a second locking extension, the first locking extension including a first vertical portion and a first horizontal portion cantilevered from the first vertical portion adjacent a first bottom end of the first vertical portion and extending laterally in a first direction perpendicular to the pull-off direction, the second locking extension including a second vertical portion and a second horizontal portion cantilevered from the second vertical portion adjace
