Abstract

The invention relates to an adapter for a product dispenser (11) with an adapter base body (19) for positioning the adapter (18) on a container opening (14) of a pressure container (12), with a swivel arrangement (23), which adjusts an actuating lever (21) with a handle (22) swivellably to the adapter base body (19), wherein the actuating lever (21) is transferable from an unlocked position (67), in which the handle (22) can be operated from a starting position (68) into an active position (69) for opening a valve (16) of the container (12), to a locked position (66), in which operation of the handle (22) is blocked.

Claims

1. An adapter for a product dispenser with an adapter base body for positioning the adapter on a container opening of a pressure container, with a swivel arrangement, which adjusts an actuating lever with a handle swivellably to the adapter base body for moving the actuating lever between an unlocked position, in which the handle for opening a valve of the container is operable from a starting position into an active position to enable outputting a medium from the pressure container, and a locked position, in which operation of the handle is blocked to prevent outputting the medium from the pressure container, wherein the swivel arrangement is formed by a swivel axis and at least one slot and the swivel axis can be arranged in a first end position and in a second end position in the at least one slot.

2. The adapter according to claim 1, wherein a displacement movement of the actuating lever is guided by the swivel arrangement and the actuating lever is displaceable relative to an output sleeve on the adapter base body.

3. The adapter according to claim 1, wherein the swivel arrangement has the at least one slot with an angled progression, by which the first and second end position for the swivel axis is separated and by which the handle is adjustable from the locked position to an unlocked position with a greater distance from the adapter base body.

4. The adapter according to claim 1, wherein the displacement movement of the actuating lever for locking and unlocking has a first displacement path, which is provided transverse to the longitudinal axis of the adapter base body, and a second displacement path connected thereto, which is inclined relative to the first displacement path.

5. The adapter according to claim 1, wherein the actuating lever has a stop, which is provided pointing towards the adapter base body and lying opposite has a projection arranged on an output sleeve of the adapter base body, which projection points towards the actuating lever and is provided as a transport safeguard.

6. The adapter according to claim 5, wherein the actuating lever is held clamped in the locked position between the adapter base body and the projection on the output sleeve.

7. The adapter according to claim 1, wherein at an end of the actuating lever lying opposite the handle there is provided the at least one slot, which forms the swivel arrangement with the swivel axis fixedly arranged on the adapter base body.

8. The adapter according to claim 1, wherein the adapter base body comprises the output sleeve, which is connected to the adapter base body via an elastic connection, so that the output sleeve is displaceable along the longitudinal axis of the adapter base body.

9. The adapter according to claim 8, wherein the elastic connection is a membrane or a joint.

10. The adapter according to claim 1, wherein in the unlocked position, an actuating element of the actuating lever engages on a cam or an annular collar on the output sleeve.

11. The adapter according to claim 5, wherein the output sleeve has a connection for actuating a valve closure member and lying opposite has a receptacle, to which a nozzle is attachable.

12. The adapter according to claim 1, wherein a cap is placeable on the adapter base body, which cap encloses the swivel arrangement and the adapter base body.

13. The adapter according to claim 12, wherein the cap has a recess, through which the actuating lever is led out and the handle is arranged outside the cap and that a tamper-evident closure is provided in the recess.

14. The adapter according to claim 13, wherein the tamper-evident closure is provided by at least one web-shaped linkage of the recess, which serves as a predetermined breaking point.

15. A product dispenser with a pressure container for receiving a medium to be output, with a valve, which closes a container opening, comprising an adapter with an adapter base body for positioning the adapter on a container opening of a pressure container, with a swivel arrangement, which adjusts an actuating lever with a handle swivellably to the adapter base body for moving the actuating lever between an unlocked position, in which the handle for opening a valve of the container is operable from a starting position into an active position to enable outputting a medium from the pressure container, and a locked position, in which operation of the handle is blocked to prevent outputting the medium from the pressure container, wherein the swivel arrangement is formed by a swivel axis and at least one slot and the swivel axis can be arranged in a first end position and in a second end position in the at least one slot and the adapter is attachable to the container opening of the pressure container.

16. The product dispenser according to claim 15, wherein the adapter is clippable or screwable onto an edge of the container opening of the pressure container.
