Preferably, the operating part 9 engages axially in the switching part 10 or vice versa.

In the illustrated example, the actuating part 9 preferably has a projection 9C which projects axially downwards and / or towards the receptacle 7 or the switching part 10 and / or is web-like and / or engages in a corresponding end-side recess 10A of the switching part 10 in Fig. 1 and 2 indicated. However, other constructive solutions are possible here.

The dispensing device 1 or the dispensing head or the receptacle 7 is fluidically connected to the container 3 or the dispensing valve 4 or connectable, in particular in Fig. 1 indicated. Particularly preferably, there is a fluidic connection to or via a valve element 4A of the dispensing valve 4. The valve element 4A is in particular tubular or nozzle-like and / or tiltable and / or depressible for actuating or opening the dispensing valve 4.

The dispensing valve 4 preferably closes automatically. In particular, the valve element 4A is resiliently biased in its closed starting position.

In the illustrated embodiment, the dispensing head or the housing part 5 or the receptacle 7 is preferably connected fluidically to the dispensing valve 4 or its valve element 4A via an optional connecting part 11.

Preferably, the connection part 11 is arranged on the inlet side on the dispensing head or on the receptacle 7, particularly preferably axially movable.

Particularly preferably, the connection part 11 is attached to the dispensing valve 4 or its valve element 4A or vice versa.

Preferably, the receptacle 7 has an at least substantially cylindrical outer contour.

Preferably, the receptacle 7 has a preferably at least substantially hollow cylindrical receiving area 7A for the switching part 10.

The receiving area 7A is preferably designed to be open towards the actuating part 9 or upwards, so that the switching part 10 can be inserted or inserted correspondingly axially.

The switching part 10 is preferably rotatably received in the receptacle 7 or in the receiving area 7A.

The discharge channels 6 close in particular radially to the receiving area 7A.

The receptacle 7 preferably has, starting from the receiving region 7A in the axial direction, a connection channel 7B for the fluidic connection of the container 3 or dispensing valve 4.

The connection channel 7B or the receptacle 7 has on the inlet side a preferably radially widened connection region 7C into which the dispensing valve 4 or its valve element 4A-particularly preferably together with the optional connection part 11-engages.

In particular, the connection part 11 is at least partially inserted or inserted in or received by the connection region 7C.

Particularly preferably, the housing part 5, optionally the nozzle inserts 8, the actuating part 9, the switching part 10 and optionally the connecting part 11 form the dispensing head, which can be connected to the container 3 or another reservoir.

Fig. 1 shows the dispensing device 1 in the unactuated state. The dispensing head is mounted on the container 3, in particular, the housing part 5 is attached to a connecting region 5A at one edge of the container 3, particularly preferably latched.

In the illustrated state, the actuating part 9 and thus also the non-rotatably connected switching part 10 is rotated such that an output channel 6 is released.

The actuating part 9 preferably has an outlet opening 9D, which is then rotated correspondingly in front of the released outlet channel 6 or its outlet. The dispensing opening 9D is preferably mouth-like in the illustrated embodiment, as is particularly apparent Fig. 3 and 5 seen. However, other designs are possible here.

Fig. 5 shows the dispensing device 1 and the dispensing head without container 3 in a perspective view in the region of the discharge side, here in the unlocked state with an open outlet. The switching part 10 preferably has a particular radial opening 10B in order to fluidly couple or release an output channel 6 as a function of the rotational position or position, that is, a fluidic connection from the connection region 7C or connecting channel 7B via or through the switching part 10 to produce the respective output channel 6.

The horizontal section according to Fig. 4 illustrates such a situation. Here, the left-facing output channel 6 is fluidly connected or released. The other, pointing to the left above output channel 6, however, is blocked by the switching part 7 and its peripheral wall. Accordingly, this wall can also be understood as a blocking section 10C.

Preferably, the switching part 10 can also occupy a blocking position or intermediate position in which both output channels 6 are locked at the same time. In this state, the dispensing head or the dispensing device 1 or the actuating part 9 is preferably blocked or blocked against an actuation or depression.

As already mentioned, the switching part 10 is rotated by corresponding rotation of the actuating part 9 in order to switch between the output channels 6 or to block (simultaneously) the output channels 6 in the blocking or intermediate position.

The two output channels 6, particularly preferably by using different nozzle inserts 8, preferably have different dispensing behavior or spray behavior. For example, a more spray or fog-like output of the product 2 can take place via an output channel 6, whereas, for example, a more jet-like or drop-shaped output takes place in the other output channel 6. The different types of output or the different output behavior can in particular be represented by corresponding symbols 13A and 13C, as in the perspective rear view according to FIG Fig. 6 indicated, made visible to the user. Further, a symbol 13C then indicates, for example, the intermediate or blocking position. In the illustrated example, the arrow 13D or another symbol on the actuating element 9 preferably points to the respective symbol 13A, 13B, 13C on the outer circumference of the dispensing head or housing part 5 depending on the rotational position of the actuating part 9 and thus depending on the rotational position of the switching part 10 , However, other constructive solutions for displaying the respective state are also possible here.

The opening 9D of the operating part 9 is moved in response to the rotational position in front of the outlet of the respective released output channel 9. So recognizes the Users also, for example, alternatively or additionally, when the dispensing device 1 or the dispensing head or the operating member 9 is in a released position and can be used directly by depressing.

The intermediate or blocking position is alternatively or additionally also visible to the user because there is no nozzle or outlet behind the opening 9D but, for example, a continuous or smooth area or a region provided with a blocking symbol, in particular of the housing part 5, located.

The actuating part 9 preferably forms a rigid cap of the dispensing head or the dispensing device 1.

Upon actuation of the dispenser 1 and the operating part 9 in the in Fig. 1 indicated actuation direction B - ie at depression - is in the illustrated, not locked state, the receptacle 7 resiliently down or to the container 3 tilts or moves. As a result, in particular via the optional connection part 11, the dispensing valve 4 - here by depressing the valve element 4A - opened. The pressurized product 2 can flow through the preferably connected to the dispensing valve 4 riser 12 through the dispensing valve 4 and valve element 4A in the dispensing head. There, the product 2 is passed through or via the optional connection part 11 in the receptacle 7, more precisely through the outlet channel 7B and through the switching member 10 and its opening 10B in the shared output channel 6 and from this particular on the respective nozzle insert 8 in the desired Way through the opening 9D in the operating part 9 output in the discharge direction A, as shown schematically in FIG Fig. 1 shown. In this context, it should be noted that the Fig. 1 the dispensing device 1 is not in the actuated state.

After completion of the operation, ie after releasing the operating part 9, the output channels 6 feathers with the receptacle 7 back up to the starting position. The actuating member 9 is moved back to the unactuated position or raised. Accordingly, the dispensing valve 4 can close automatically again. The product issue is ended.

The dispensing device 1 or the actuating part 9 preferably has a blocking element 9E which, in the intermediate or blocking position, blocks a depression, ie an actuation. The blocking element 9E is in the blocking position of the actuating part 9 of a stop 5 B on the housing part 5, as in Fig. 3 and 4 indicated, blocked against a depression or moving in the direction of movement B.

The blocking element 9 is preferably arranged on the side opposite to the opening 9D.

The stopper 5B is preferably arranged on the inside of the housing part 5 and / or integrally formed on the housing part 5 or formed by it.

The stop 5B is preferably arranged on the housing channel 5 on the side opposite the dispensing channels 6.

The stop 5B is preferably designed as an axial run-on surface and / or in the circumferential direction extending annular portion.

The blocking element 9E is preferably designed like a rib and / or as an axial and / or radially inwardly projecting stop edge.

Particularly preferably, the actuating member 9 is movable or rotatable only by overcoming a resistance during rotation of the intermediate or locking position in one of the two release positions for output via the respective output channel 6. For this purpose, in the illustrated embodiment, preferably a respective rib 5C is formed, which must accordingly be run over or overcome by the blocking element 9E in order to reach the respective subsequent release position.

The two ribs 5C are preferably arranged in each case in the region of the two circumferential ends of the stop 5B. However, other constructive solutions are possible.

In the unlocked position or release position, the actuating member 9 can be depressurized in the direction of actuation B. In particular, this is made possible by the fact that in this position, the locking element 9E does not run on the stop 5B or strikes, but can dive into a corresponding recess 5D in the housing part 5.

Particularly preferably, the housing part 5D has a particular inner ring portion 5E, for example, carries or forms the stopper 5B and / or is accordingly excluded to form the recesses 5D.

Preferably, the ring portion 5E carries on the discharge side the discharge channels 6 and / or extends between them, particularly preferably to cover the opening 9D of the operating part 9 in the intermediate position on the back.

Particularly preferably, the actuating part 9 is latching connected to the housing part 5 and / or the receptacle 7. For example, corresponding latching lugs or latching projections 5F in the housing part 5D or on the ring area 5E and / or a collar 7D on the receptacle 7 are formed for this purpose, to the desired latching engagement with the actuating part 9 and / or a positive locking of the operating part 9 against axial withdrawal or lifting to enable or guarantee.

In the illustrated example, the actuating member 9, for example, inwardly projecting projections 9F and 9G, which engage around the latching projections 5F and the collar 7D or engage behind. However, other constructive solutions are possible.

Fig. 7 shows in a perspective view, the switching part 10 according to the illustrated embodiment. Here, the switching part 10 is at least substantially designed as a downwardly open sleeve having in the cylindrical wall in particular the hole-shaped radial opening 10B. The sleeve or the switching part 10 is downwardly, so axially open to the connection channel 7B, so that axially entering product 2 via the opening 10B in the respectively connected or released output channel 6 can flow out or continue to flow.

At the upper end, ie at the end facing the actuating part 9, the switching part 10 is closed and has the switching part 10, the possibility of engagement, here preferably in the form of the recess 10 A, to the switching part 10 rotatably to connect or rotate.

The switching part 10 preferably has a seal 10D, which is arranged in particular in the region of the upper end and / or formed circumferentially.

In particular, the seal 10D serves a radial seal and / or a seal between the receptacle 7 and the switching part 10, in particular so that pressurized product 2 can not escape axially from the receptacle 7 in the direction of the actuating part 9.

The seal 10D is preferably formed as a circumferential lip and / or flexible lip.

The seal 10D is preferably integrally formed.

The seal 10D is preferably designed to be self-sealing, in particular so that it automatically spreads outwards when the product pressure is present or rests against the cylindrical inner wall of the receiving region 7A of the receptacle 7.

The opening 10B of the switching part 10 is preferably arranged axially below the seal 10D.

Fig. 8 shows in a to Fig. 7 corresponding perspective view of the switching part 10 according to another embodiment. Here, the opening 10B is not in the manner of a bore, but in the manner of a slot, in particular an axial slot, which is particularly preferably open to the lower end of the switching part 10, formed.

Fig. 9 shows in a to FIGS. 7 and 8 corresponding perspective view of the switching part 10 according to a further embodiment. Here, the circumferential wall is formed by preferably tab-like locking portions 10C, which extend axially downwards from the upper annular region and cover the inlet openings of the output channels 6 as a function of the rotational position of the switching part 10.

The preferably flap-like design of the locking portion 10C of the switching part 10 supports the automatic sealing of a locked discharge channel 6, characterized in that the pending product pressure pushes the locking portion 10C against the inlet to be closed of the respective output channel 6 radially outward and thus in the sealing position.

The discharge head or receptacle 7 preferably forms an outlet space for the product 2 to be dispensed. This discharge space is preferably initially reduced in volume upon actuation of the operating member 9 prior to opening of the dispensing valve 4 and later after completion of the actuation, after closure of the dispensing valve 4, again enlarged in volume. By the variation in volume can be achieved that in the outlet space, so in particular in the receptacle 7 and in the connected output channel 6, befindliches product 2 is retained therein after completion of delivery and in particular not subsequently undesirably exits the outlet of the connected output channel 6 , This volume variation is preferably realized here by corresponding axial movement of the optional connection part 11 relative to the receptacle 7 or in the connection region 7C in the representation example.

Fig. 10 shows in a perspective view of the connector part 11 according to the preferred embodiment. The connection part 11 has a seal 11A for the radial sealing of the connection part 11 in the receptacle 7 or in the connection region 7C.

The connecting part 11 further preferably has a spring portion 11 B, 11 elastically resiliently in the in the in the Fig. 1 and 2 illustrated, axially withdrawn position biases. This bias voltage is preferably designed such that upon actuation of the dispensing head or of the actuating part 9, ie upon depression of the receptacle 7, first the connecting part 11 (further) is axially inserted into the connection area 7C under deformation of the spring section 11B before the dispensing valve 4 is opened by depressing the valve member 4A for product delivery.

After actuation first closes the dispensing valve 4 and then moves the connector 11 back out of the receptacle 7 axially slightly due to the restoring force of the spring portion 11 B, whereby the desired increase in volume of the outlet is achieved to befindliches in the receptacle 7 and in the connected output channel 6 Retain product 2 against undesired leakage.

The proposed embodiment allows a very simple structure of a few components and a simple assembly. In particular, only an axial insertion of the nozzle inserts 8, the switching part 10 and / or the connection part 11 is required. Further, the actuating member 9 at corresponding Rotary alignment simply axially mounted on the housing part 5 with inserted switching part 10 and snapped. This assembly or pre-assembly of the dispensing head is already done.

The housing part 5 is preferably injection molded from a suitable plastic.

The same applies preferably to the actuating part 9.

The switching part 10 is preferably made of a relatively soft plastic, in particular of a plastic, which is softer than the plastic of the housing part 5 and the receptacle 7.
