Abstract

A dispensing device (2) for dispensing a fluid (F) is proposed. The dispensing device has a conveying device (4) for conveying the fluid from a container, which can be actuated by means of an actuating lever (21), the actuating lever being lockable against unwanted actuation by means of a blocking device (27).

Description

The present invention relates to a dispensing device for dispensing a fluid according to the preamble of claim 1 and a dispenser for dispensing a fluid according to the preamble of claim 12.

In particular, the present invention relates to a dispenser for storing and dispensing or dispensing cleaning agents or pharmaceutical or cosmetic fluids, in particular liquids. A fluid can be received in a container of the dispenser, which fluid can be conveyed out of the container by means of a dispensing device attached to the container and can be dispensed by means of the dispensing device. The fluid can be delivered in various delivery forms, for example as a spray or aerosol or as a foam.

the WO 2019/175349 A1 relates to a dispensing device for dispensing a fluid, which has a pumping device for conveying the fluid from a container. The pumping device has a bellows for pumping and can be actuated by means of a manually operable actuating lever. The actuating lever can be secured against undesired actuation. In a first embodiment, an actuating arm of the actuating lever is folded up into a secured position, in particular secured on a dispensing head of the dispensing device. In a second embodiment, the actuating lever has a blocking element which can be pivoted relative to the actuating arm and which can be arranged between the actuating arm and a housing of the dispensing device and thus blocks pivoting of the actuating lever.

It is an object of the present invention to enable a simple, reliable and/or safe function or handling and/or a simple structure of a dispensing device or a dispenser and/or an actuation and/or an escape of fluid during the transport of a To prevent donors in a simple and inexpensive way.

The above object is achieved by a dispensing device according to claim 1 or by a dispenser according to claim 12. Advantageous developments are the subject matter of the dependent claims.

A proposed dispensing device is designed for dispensing a fluid, in particular contained in a container assigned to it and/or connected to the dispensing device.

The dispensing device has a delivery device for delivering the fluid. The delivery device is preferably a pump device or designed as a pump or has such a device. The conveying device or pumping device particularly preferably has flexible bellows for conveying the fluid. In particular, the fluid can be conveyed into the bellows by an expansion of the bellows or a negative pressure resulting from the expansion and released from the bellows by a compression of the bellows. However, other solutions are also possible here. For example, the pump device can have a pump piston or the like as a conveying element instead of a bellows. Furthermore, the conveying device can also be implemented without a pump or pumping device, for example in the case of a pressurized container.

The dispensing device has a manually operable actuating lever for actuating the conveying device or dispensing device. The actuating lever is preferably arranged or mounted pivotably on the dispensing device. For this purpose, the dispensing device has a corresponding bearing part which is designed for the pivot bearing of the actuating lever.

According to the proposal, the operating lever can be locked in a locked position by means of a locking device to prevent (unwanted) actuation. In this way, it is possible to prevent fluid from escaping unintentionally from the dispenser during the delivery or transport of a dispenser that is filled with a liquid and has a proposed dispensing device. In particular, it is not necessary to provide an additional transport safety device or one separate from the dispenser or the dispensing device or to attach it to the dispensing device or the dispenser. This enables cost-effective production and/or delivery, since in particular additional fuses or fuse parts can be dispensed with. In particular, the proposed solution is also particularly environmentally friendly since less waste is produced.

According to one aspect of the present invention, the dispensing device or the dispenser provided with the dispensing device is designed in such a way that the operating lever can be displaced relative to the bearing part in order to move the operating lever out of the To move or bring locking position in an operating position. In the operating position, the operating lever is unlocked or pivoting of the operating lever is released. In this way, a blocking device is realized that has a particularly simple and inexpensive design and/or is easy and comfortable to use.

The blocking device is particularly preferably formed by the actuating lever and/or the bearing part. Additional parts can thus be dispensed with, which is conducive to a simple and cost-effective construction. This is conducive both to a simple and inexpensive construction and to easy and comfortable operation.

The unlocking of the actuating lever is preferably reversible. In other words, it is preferably possible to move the actuating lever from the actuating position (again) into the blocking position or to block it (again) as required. This is conducive to safe handling of the dispensing device.

The actuating lever can preferably be displaced linearly from the blocking position into the actuating position and/or from the actuating position into the blocking position or along a curved path that is preferably only slightly curved. This is conducive to a simple structure and simple and comfortable operation.

The actuating lever can preferably be displaced in a latching manner from the blocking position into the actuating position and/or from the actuating position into the blocking position. This is conducive to a simple and/or safe structure and simple and/or safe operation.

The actuating lever is preferably latched or held latched in the blocking position and/or actuating position. In particular, a certain holding force must be overcome in order to move the actuating lever from the locked position to the actuating position, or vice versa. In this way it can be ensured that the dispensing device or the actuating lever is not accidentally unlocked or locked.

The actuating lever preferably snaps into the actuating position automatically when unlocked and/or when locked (again) in the locked position. Furthermore, the snapping can be heard and/or felt, so that a user has an auditory and/or receives haptic feedback that the actuating lever has assumed the actuating position or locked position. This is conducive to simple and comfortable operation.

For unlocking, the actuating lever can preferably be pushed in the direction of a housing of the dispensing device or pushed partially into the housing. This is conducive to particularly simple handling. In particular, the actuating lever can first be pushed (in) in a flowing hand movement, so that it is shifted from the blocking position to the actuating position and then pushed down or pivoted in order to actuate the dispensing device or to dispense the fluid. Correspondingly, the actuating lever can preferably be pulled or pulled out in the opposite direction for locking (again).

The actuating lever is preferably locked against pivoting by a form fit in the locking position. A particularly simple blocking device is realized in this way.

The blocking device, in particular the actuating lever or the bearing part, preferably has a blocking element, the blocking element blocking pivoting of the actuating lever in the blocking position, in particular positively, and releasing it in the actuating position. In particular, the blocking element engages in a corresponding recess of the blocking device in the blocking position. In this way, a particularly simple blocking device or blocking is implemented.

The blocking element is particularly preferably arranged on the actuating lever and the recess on the bearing part or formed by it, or vice versa the blocking element on the bearing part and the recess on the actuating lever. As a result, additional parts can be dispensed with and/or a particularly simply constructed blocking device can be implemented.

According to a further aspect of the present invention, which can also be implemented independently, the dispensing device or the dispenser provided with the dispensing device has—in addition to the blocking device—a safety device. The security device is designed to secure the dispensing device or the actuating lever or the locking device against unlocking. A direct unlocking of the locking device - at least when using it for the first time - is preferably prevented or blocked by the safety device. In particular, the safety device must first be actuated or the locking device unlocked. This is conducive to a particularly safe assembly or transport, in particular since the dispensing device or the actuating lever is doubly secured or blocked.

Corresponding terms are used below to differentiate between the blocking device and the safety device. Terms such as "block", "unblock", "blocking", "blocking element", etc. preferably relate exclusively to the blocking device, unless explicitly stated otherwise. Correspondingly, terms such as “securing”, “unsecuring”, “securing”, “securing element”, etc. preferably relate exclusively to the securing device, unless explicitly stated otherwise.

The unlocking of the dispensing device, the locking device or the actuating lever is preferably irreversible. In particular, the safety device can only be actuated or unlocked once or only before it is used for the first time. It is preferably not possible to save again by means of the safety device. If required, it is then preferably sufficient to block the dispensing device or the actuating lever by means of the blocking device. This is conducive to particularly simple handling.

The security device preferably serves as an originality seal or closure. From the state or the position of the safety device (actuated/unlocked or not actuated/secured), a user can preferably identify whether the delivery device is in the delivery state or has already been used/unlocked. This is conducive to safe handling.

The safety device preferably has a safety element which blocks the unlocking of the actuating lever, in particular a displacement of the actuating lever from the blocked position into the actuating position, preferably in a form-fitting manner.

The securing element is particularly preferably arranged on the actuating lever or formed by it. As a result, a particularly simple construction of the safety device is realized. Alternatively, however, the fuse element can also another part of the dispenser, for example a housing. The securing element is preferably formed in one piece with the actuating lever or another part of the dispensing device.

The securing element, in particular in its securing position, is preferably arranged in such a way that it blocks an in particular linear displacement, in particular a (re)pressing, of the actuating lever. Particularly preferably, the securing element, particularly in its securing position, rests against the housing of the dispensing device or comes into contact before the actuating position is reached, so that the displacement or pushing (in) of the actuating lever is prevented or blocked.

In its securing position, the securing element is preferably held on the actuating lever by a cohesive bond and/or by a predetermined breaking point. This is conducive to a particularly simple structure. In particular, it can be realized in a particularly simple manner that the unlocking is irreversible.

The securing element can be brought out of its securing position in order to unlock or release the blocking device or the displaceability of the actuating lever. For this purpose, the securing element can particularly preferably be pressed in, folded away or folded up and/or removed from the dispensing device or the actuating lever, for example by breaking out. This enables a particularly simple unlocking. Furthermore, a missing, pressed-in or folded-up safety element indicates that the dispensing device, the actuating lever or the locking device is unlocked. The function as a seal of originality is thus implemented in a particularly simple manner.

The proposed dispenser for dispensing a fluid is provided with the proposed dispensing device and a container. The fluid can be conveyed out of the container with the dispensing device and can be dispensed from the dispenser by means of the dispensing device. This results in the corresponding advantages.

The aforementioned and following aspects and features of the present invention can be combined with one another as desired, but can also be implemented independently of one another.

1 shows a proposed dispenser 1 with a proposed dispensing device 2 and a container 3.

A fluid F can be accommodated in the dispenser 1 or container 3 . The dispensing device 2 is designed or provided to convey the fluid F out of the container 3 and to discharge or dispense the fluid F. FIG.

The fluid F is preferably a (low-viscosity) liquid, in particular a cleaning liquid or the like, but can also have a viscous to pasty consistency or a high viscosity.

The fluid F is dispensed with the dispensing device 2 preferably or optionally as a spray or aerosol and/or as a foam. However, other solutions are also possible here.

The dispenser 1 is preferably marketed as a disposable item and filled with the fluid F and/or sold to an end customer. The dispenser 1 is particularly suitable for cleaning fluids, such as glass cleaner or the like, but can also be used for any other fluids F.

The dispenser 1 and/or the dispensing device 2 preferably have/have a (common) central or longitudinal axis L.

The axis L is preferably aligned at least substantially perpendicularly (vertically) in a usual storage position and/or use position of the dispenser 1, as also shown in the figures. In particular, during use, the dispensing device 2 or an outer housing 14 of the dispensing device 2 is usually at the top and the container 3 is at the bottom. In particular, the axis L, at least in the storage position, runs at least substantially parallel to the force of gravity. In the storage position, the dispenser 1 preferably stands on a bottom of the container 3.

In the context of the present invention, an "axial" direction or movement is preferably understood to mean a direction or movement which runs along or parallel to the axis L. In an analogous manner, the term "radial" preferably also refers to the L axis.

In the present invention, the terms “top” and “bottom” and modifications thereof and terms similar thereto preferably have the usual general meaning with regard to the preferred orientation or position of use and in the present invention preferably refer to the storage position of the dispenser shown in the figures 1 or the delivery device 2.

The proposed dispensing device 2 has an actuating lever 21 that can be pivoted in particular. The fluid F is dispensed from the dispenser 1 or the dispensing device 2 preferably by manually actuating or pivoting the actuating lever 21.

The delivery device 2 preferably has a delivery device 4 for delivering the fluid F, in particular from the container 3 . The conveying device 4 can preferably be actuated by means of the actuating lever 21 .

In the preferred embodiment shown, the delivery device 4 is preferably designed as a pump device and/or has a pump device or pump. In particular, the delivery device 4 is designed to deliver or pump the fluid F—preferably only in the unlocked state—from the container 3 into the delivery device 2 and/or to deliver it from the delivery device 2 or via a closure or delivery element 36 . By manually actuating or pivoting the actuating lever 21 , the fluid F is preferably pumped out of the container 3 and/or released from the dispensing device 2 or via the closure or dispensing element 36 .

According to the proposal, the dispensing device 2 or the actuating lever 21 can be locked or locked in a locked position, in particular in the delivery state. In the blocking position, actuation or pivoting of the actuating lever 21 is blocked or not possible. In particular, an actuation of the delivery device 4 or a delivery of the fluid F is locked or blocked. The state of the dispensing device 2 with the actuating lever 21 in the blocked position is referred to below as the blocked state.

In 1 the dispensing device 2 is shown in the locked state or with the actuating lever 21 in the locked position. Figure 2A is an enlarged view of the dispenser 2 according to FIG 1 in lockdown.

Figure 2B shows the dispensing device 2 in a section corresponding to FIG Figure 2A in an unlocked state or with the operating lever 21 in an operating position. In the unlocked state or in the operating position, manual actuation or manual pivoting of the operating lever 21 or the delivery device 4 for dispensing the fluid F is enabled or unlocked.

Figure 2C shows the dispensing device 2 in a section corresponding to FIG Figure 2A and Figure 2B in the actuated state or with the actuating lever 21 actuated, in particular pivoted, or with the conveyor device 4 actuated.

In the following, first a preferred structure of the delivery device 2, in particular the conveyor 4, based on 1 and Figures 2A to 2C described in more detail. A preferred locking device 27 and safety device 30 are described below.

The design of the conveyor device 4 as a pump device, as described below, is preferred, but not essential. The following description is therefore only an example.

In the illustrated preferred embodiment of the conveying device 4 , it has a bellows 5 or a pumping device is formed by the bellows 5 . Instead of the bellows 5, however, other solutions for a pumping device are also possible. For example, instead of the bellows 5, a cylinder-piston arrangement is also conceivable, for example similar to that in FIG U.S. 3,840,157 cylinder-piston arrangement described.

The conveyor device 4 preferably has a conveyor housing 4A. The conveyor housing 4A is preferably at least essentially sleeve-like or ring-like or hollow-cylindrical and/or arranged coaxially to the L axis.

The pumping device and/or the bellows 5 are preferably at least partially arranged within the delivery housing 4A or accommodated in the delivery housing 4A. The bellows 5 is preferably arranged inside the conveyor housing 4A and/or coaxially thereto.

The bellows 5 is preferably flexible and/or elastically deformable or the bellows 5 consists of a flexible and/or elastically deformable material.

The bellows 5 is preferably designed to return, after deformation, to an initial position assumed before the deformation, or an unactuated position or rest position.

The bellows 5 is preferably prestressed and/or (slightly) compressed in the dispenser 1 or the dispensing device 2 or the delivery device 4 or the delivery housing 4A installed or arranged therein. In particular, this supports reliable delivery of the fluid F.

The bellows 5 is preferably at least essentially cylindrical or hollow-cylindrical. A lateral surface or side wall 6 of the bellows 5 is preferably wavy or corrugated. This preferably increases the flexibility and/or elastic restoring force that drives or moves the bellows 5 back into the starting position or rest position. Furthermore, the wavy design preferably avoids damage when the bellows 5 is deformed and/or increases the stability of the bellows 5 .

The bellows 5 or the side wall 6 preferably runs coaxially to the central or longitudinal axis L of the dispenser 1 or the dispensing device 2.

The conveying device 4 or the bellows 5 preferably has an inlet 5A for the fluid F, an outlet 5B for the fluid F and a pump chamber or interior space 5C for receiving the fluid F. The interior space 5C is preferably formed between the inlet 5A and the outlet 5B and/or is delimited laterally or radially by the side wall 6 .

The delivery device 4 or the bellows 5 preferably has an inlet valve 7 at the inlet 5A and an outlet valve 8 at the outlet 5B. The inlet valve 7 and the outlet valve 8 are preferably each designed as a one-way valve. The inlet valve 7 enables or controls a supply of the fluid F to the delivery device 4 or the bellows 5. The outlet valve 8 enables or controls a discharge of the fluid F from the outlet 5B of the delivery device 4 or the bellows 5.

The inlet valve 7 and the outlet valve 8 open and/or close preferably under pressure control or automatically, in particular by a pressure difference present at the respective valve 7, 8. A preferred specific design of the valves 7, 8 will be discussed in more detail later.

The conveyor device 4 or the bellows 5 preferably has a base 9 . The base 9 is preferably designed as a component that is separate or separately manufactured from the bellows 5 .

The base 9 is preferably axially movable and/or located within the conveyor housing 4A.

The base 9 is connected to the bellows 5, in particular on the inlet side. The bellows 5 can be connected to the base 9 in a non-positive or frictional manner and/or by means of a material bond or fastened to the base 9, in particular latched, glued, welded and/or molded on.

The base 9 preferably has a bottom element 10 . The base element 10 is preferably designed like a plate and/or preferably forms a (lower) closing surface or a (lower or end-side) closure of the conveyor device 4 or the bellows 5 or the interior space 5C. The base element 10 is preferably designed at least essentially in the manner of a circular disk and/or forms an annular surface.

The base 9 preferably has a feed channel 11 for the fluid F, which runs in particular axially or parallel to the axis L, or forms such a feed channel. The feed channel 11 preferably opens into the inlet 5A of the bellows 5.

The feed channel 11 is preferably formed or delimited by a line 12 of the base 9 .

The line 12 and the base element 10 are preferably formed in one piece.

The base 9 with the bottom element 10 and the supply line 12 can be designed or produced, for example, as an injection molded component and/or made of plastic.

The base element 10 is preferably arranged at a distance from the upper or the bellows 5 facing and/or the lower or the container 3 facing axial end of the line 12 .

The line 12 particularly preferably forms a connection and/or protrudes downwards or into the container 3 .

The dispenser 1 or the dispensing device 2 or the conveying device 4 preferably has a riser 13 for the fluid F. The riser 13 is preferably to the bellows 5 and the base 9, in particular to the feed channel 11 and the Line 12 is connected and/or arranged at a lower end or at an end of the base 9 or line 12 facing away from the bottom element 10 and/or the bellows 5 . The riser 13 can be plugged into the line 12 or slipped onto the line 12 or connected to the line 12 in some other way.

The riser 13 preferably forms an extension of the line 12 or the feed channel 11. Preferably, the line 12 and the riser 13 together form and/or delimit the feed channel 11.

The dispenser 1 or the dispensing device 2 preferably has an outer housing 14 .

Preferably, the outer housing 14 forms an outer housing of the dispenser 2 or part of an outer housing.

The conveyor device 4 is preferably arranged or held in the outer housing 14 . The outer housing 14 is particularly preferably designed to accommodate the conveying device 4 and/or the bellows 5 .

In the illustrated example, the outer housing 14 is formed in two parts or has an upper housing part 14A and a lower housing part 14B. However, other solutions are also possible here.

The outer housing 14, in particular the upper housing part 14A, preferably has a fastening part 14C for connecting or fastening the conveying device 4 or the bellows 5 to/on the outer housing 14.

The dispensing device 2 or conveying device 4 preferably has or forms an outlet channel 15 running in particular transversely or perpendicularly to the axis L. The outlet channel 15 is preferably arranged in the outer housing 14 . The outlet channel 15 is preferably fluidically connected or can be connected to the outlet 5B and opens into a channel opening 16. The fluid F can preferably exit via the outlet channel 15 and the channel opening 16 from the outer housing 14 or from the dispenser 1 or the dispensing device 2 be given.

In the example shown, the outlet channel 15 is preferably formed by the conveyor device 4 or its conveyor housing 4A. However, other solutions are also possible here. For example, the outlet channel 15 could also be formed by the outer housing 14, in particular its upper housing part 14A. It is also possible for the outlet channel 15 to be designed as a separate component which is preferably inserted or inserted into the outer housing 14 .

As already mentioned at the outset, the dispensing device 2 or the outer housing 14 preferably has the closure or dispensing element 36 . The closure or dispensing element 36 is preferably arranged on or behind the outlet channel 15 or the channel opening 16 in the direction of fluid dispensing. The fluid 2 is preferably dispensed at the closure or dispensing element 36 or must first pass through the closure or dispensing element 36 before it can be dispensed.

The closure or dispensing element 36 can be designed in such a way that when the fluid F passes through, a desired dispensing form of the fluid F is achieved or effected, for example as a spray or aerosol and/or foam. In particular, the closure or dispensing element 36 can have a passage opening with a grid (not shown), through which the fluid F must pass before dispensing.

The closure or dispensing element 36 can be designed to optionally or as needed close the channel opening 16 (fluid-tight) and/or to generate different forms of dispensing the fluid F.

The closure or dispensing element 36 is preferably rotatable in order to selectively arrange different passage openings behind the channel opening 16 and/or to close or cover the channel opening 16 (fluid-tight).

In the preferred embodiment shown, the outlet channel 15 is preferably arranged eccentrically on the conveyor housing 4A. It is therefore in 1 and Figures 2A to 2C behind the cutting plane. Correspondingly, a passage opening of the closure or release element 36 is not visible/shown.

When using the dispenser 1 for the first time, it may be necessary to first actuate the conveyor 4 or the actuating lever 21 a few times in order to remove air from the conveyor 4 and/or fluid F from the first time To promote container 3 in the dispenser 2 and the conveyor 4 and the bellows 5 or to pump.

When the delivery device 4 or the activation lever 21 is actuated, the fluid F preferably passes via the supply channel 11 or the line 12 and/or the riser 13 from the container 3 into the delivery device 2 or the delivery device 4 or the bellows 5.

The inlet valve 7 is preferably designed in such a way that it opens when the fluid F is conveyed with the conveying device 4 or when the fluid pressure is present on the feed channel side and thus enables the fluid F to be conveyed from the feed channel 11 through the inlet valve 7 into the interior space 5C of the bellows 5 .

The bellows 5 is preferably in an unactuated or rest position, which is in 1 , 2A and 2 B is shown and in an actuated or compressed position shown in Figure 2C is shown, positionable or arrangeable or deformable in these positions.

The bellows 5 is preferably designed to automatically assume or return to the rest position, in particular by elastic recovery, if no force is acting on the bellows 5 that deforms the bellows 5 from the rest position. The bellows 5 is preferably compressed axially or along the axis L in the actuated position. The compression of the bellows 5 takes place in particular axially or parallel to the axis L and/or by pushing or folding the corrugated side wall 6 together.

On the outlet side, the bellows 5 is preferably kept stationary or immovable, in particular by or on the delivery housing 4A and/or outer housing 14. Preferably, the outlet 5B and/or the delivery housing 4A change their (axial) position relative to the outer housing 14 and/or the container 3 when the bellows 5 is compressed or deformed or when the dispensing device 2 or the dispenser 1 is actuated.

The bellows 5 is preferably movably held or fastened on the inlet side, in particular by or on the base 9. The inlet 5A and/or the base 9 preferably change their (axial) position relative to the conveyor housing 4A, the Outer housing 14 and/or the container 3 when the bellows 5 is compressed or deformed or when the dispensing device 2 or the dispenser 1 is actuated.

When the conveying device 4 or the actuating lever 21 is actuated or actuated, the base 9 preferably moves axially, in particular upwards or in the direction of the bellows 5, and/or the bellows 5 is compressed or reduced in volume.

The compression or reduction in volume of the bellows 5 causes an increased pressure of the fluid F located in the interior 5C of the bellows 5, so that the fluid F is present at the outlet valve 8 with an increased pressure, as a result of which the outlet valve 8 preferably opens.

The compression of the bellows 5 preferably has the effect that the fluid F enters the outlet channel 15 through the outlet valve 8 and leaves it via the channel opening 16 or the discharge element 36 and is thus discharged from or by the discharge device 2 .

When the actuation of the conveying device 4 is terminated or no compressive force acts (any longer) on the bellows 5, the bellows 5 preferably returns to the rest position, in particular by elastic recovery.

The expansion of the bellows 5 from the compressed or actuated position to the rest position preferably reduces the pressure in the interior 5C of the bellows or creates a negative pressure in the bellows 5 or its interior 5C during the expansion, which preferably causes the outlet valve 8 closes. Furthermore, the negative pressure preferably opens the inlet valve 7 so that fluid F present in the supply channel 11 at the inlet valve 7 flows or can flow through the inlet valve 7 into the interior 5C of the bellows 5 .

The inlet valve 7 is preferably formed by the line 12 and the bellows 5 . In particular, the inlet valve 7 or the bellows 5 has a valve element 7A formed in one piece with the bellows 5 . When the inlet valve 7 is in a closed position, the valve element 7A preferably closes an opening 11A at the end or opening into the interior 5C of the feed channel 11 or the line 12 in a fluid-tight manner. In particular, the opening 11A is sealingly covered by the valve element 7A—at least in the closed position.

The valve element 7A is preferably held by one or more, in particular flexible and/or web-like, arms of the bellows 5 (not shown). The valve element 7A is preferably biased against the opening 11A or the feed channel 11, in particular by means of the arms.

The outlet valve 8 is preferably formed by an in particular ring-like sealing lip 8A which—at least in the closed state of the outlet valve 8—seals against a counter-surface 8B, which is preferably ring-shaped and/or arranged coaxially to the axis L, and is in particular prestressed against the counter-surface 8B . When the outlet valve 8 is in an open position, the sealing lip 8A is lifted off the mating surface 8B, so that a gap is formed between the sealing lip 8A and the mating surface 8B, through which the fluid F can escape from the interior 5C of the bellows 5 and into the outlet channel 15 can occur.

The conveyor housing 4A preferably has or forms the mating surface 8B.

The delivery housing 4A preferably has an opening through which the fluid F enters the outlet channel 15 (not shown). As already mentioned, in the preferred embodiment shown, the outlet channel 15 is preferably arranged eccentrically on the conveyor housing 4A and is therefore in 1 and Figures 2A to 2C behind the cutting plane. Correspondingly, the opening in the conveyor housing 4A is not visible/shown in the figures.

Preferably, the dispenser 1 or the dispensing device 2 is designed in such a way that when the conveyor device 4 is actuated, the container 3 is or is automatically aerated, so that during or through the promotion and/or dispensing of the fluid F from the Container 3 no (too high) negative pressure in the dispenser 1 or the container 3 arises. Such a negative pressure could lead to a deformation of the container 3 and/or prevent or impede (further) delivery of the fluid F from the container 3, which is undesirable.

The dispenser 1 or the dispensing device 2 is preferably designed such that a ventilation gap 17 is formed when the conveying device 4 is actuated, in particular when the bellows 5 or the base 9 moves axially the ventilation of the container 3 is made possible or takes place, as in particular in Figure 2C shown.

It is also possible that one or more of said parts 14, 14A, 14B, 14C, 4A, 20 are designed in one piece or form different sections of a single component.

The delivery device 2 or conveyor device 4 has the actuating lever 21 for the manual actuation of the delivery device 2 or the conveyor device 4 in particular. Preferably, the conveying device 4 is actuated or the bellows 5 is compressed for dispensing the fluid F (exclusively) by (manual) actuation of the actuating lever 21 by a user (not shown).

As already mentioned, it is also possible that the properties and features of the actuating lever 21 described below, in particular with regard to securing/blocking against actuation, independently of the realization of the delivery device 4 by or with a flexible bellows and/or as a pump device he follows.

The actuating lever 21 is in particular in Figures 4 and 5 shown. 4 12 is a perspective view of the operation lever 21. figure 5 is a view of the operating lever 21 from below when the dispenser 1 or the dispensing device 2 is in the normal position of use.

The actuation section 22 is preferably designed for manual actuation by a user (not shown).

The actuating section 22 can be swung or curved and/or shaped ergonomically. This is conducive to easy and convenient operation.

The lever arm 23 is preferably for driving or activating the conveying device 4, in particular for actuating or compressing the bellows 5 and/or for axially moving the base 9, in particular upwards or in the direction of the outlet 5B and/or the upper housing part 14A , educated.

The lever arm 23 is preferably eccentrically and / or arranged on an end portion of the actuating portion 22, in particular so that on the Actuating section 22 the greatest possible leverage can be generated during actuation.

The lever arm 23 and the actuating section 22 are preferably arranged transversely, in particular at least essentially perpendicularly, to one another.

Particularly preferably, the lever arm 23 has two legs 23A running parallel to one another, in particular designed arm-like or web-like, which are connected on one side to the actuating section 22 or arranged on it. Preferably, the legs 23A are rigidly interconnected, for example at or near the end face opposite the actuating portion 22, by a portion 23B disposed transversely or perpendicularly to the legs 23A. In this way, a lever arm 23 that is both stable and material-saving is formed. However, other solutions are also possible here.

The dispensing device 2 preferably has a bearing part 24 on which the actuating lever 21, in particular the lever arm 23, is movable, in particular pivotable, mounted or can be mounted.

In the illustrated example, the connecting part 20 has the bearing part 24 or forms it, as in particular in 3 shown. However, other solutions are also possible here. In particular, the bearing part 24 can also be arranged or formed on the conveyor device 4, in particular its conveyor housing 4A, the outer housing 14, in particular the lower housing part 14B, or another part of the delivery device 2.

The bearing part 24 preferably has a bearing element 25, in particular a bearing journal. In the example shown, the bearing part 24 preferably has two bearing elements 25 lying opposite one another.

The pivot axis S preferably runs through the bearing part or the bearing element(s) 25, and/or is defined by the bearing part 24 or the bearing element(s) 25, as in particular in 3 shown.

The actuating lever 21 preferably has one or more bearing sections 26 corresponding to the bearing part 24 or the bearing element(s) 25 on. The bearing section(s) 26 are preferably recesses for engagement of the bearing element(s) 25 and/or latching elements for latching with the bearing element(s) 25.

In the illustrated example, one bearing element 25 preferably engages in each leg 23A of the lever arm 23 or each of the legs 23A has corresponding bearing sections 26 for a bearing element 25 .

However, other solutions are also possible here. For example, conversely, the bearing part 24 could have one or more bearing sections 26, in particular recesses, and the actuating lever 21, in particular the lever arm 23, one or more bearing elements 25.

Figures 6A to 6C show perspective representations of the actuating lever 21 connected to the bearing part 24 in three different positions, which correspond to those in Figures 2A to 2C correspond to the positions shown. Figure 6A shows the operating lever 21 in the locked position, corresponding to FIG Figure 2A . Figure 6B shows the operating lever 21 in the unlocked, unactuated position or operating position, corresponding to FIG Figure 2B . Figure 6C shows the actuating lever 21 in the actuated or pivoted position, corresponding to FIG Figure 2C .

The respective positions of the actuating lever 21 and the associated blocking/safety and actuating mechanisms or devices or states are explained in more detail below.

The locking position of the actuating lever 21 or a locking device 27 of the dispensing device 2 is in the figures 1 , 2A and 6A shown. The dispenser 1 or the dispensing device 2 is accordingly in a blocked state.

In the locked state or in the locked position, an actuation or pivoting of the actuating lever 21 is preferably locked or blocked. In particular, an activation or actuation of the delivery device 4 and/or a delivery of fluid F is locked or blocked.

The dispensing device 2 preferably has a blocking device 27 which blocks or blocks the actuation of the actuating lever 21 or of the conveying device 4 in the blocked state or in the blocked position.

The blocking device 27 or the blocking state is preferably realized or formed by a form fit, in particular of the actuating lever 21 and the bearing part 24 .

The blocking device 27 preferably has a blocking element 28 .

In the locked position or in the locked state, the locking element 28 preferably engages in a form-fitting manner in a corresponding recess 29 .

The blocking device 27 is preferably formed by the blocking element 28 and the recess 29 and/or has them.

In the illustrated example, the blocking element 28 is arranged or formed on the actuating lever 21, in particular on the lever arm 23, particularly preferably on its section 23B, as in particular in Figures 4 and 5 shown.

The blocking element 28 is preferably designed or manufactured in one piece with the actuating lever 21 or lever arm 23 .

The blocking element 28 is preferably cuboid, in particular at least essentially cube-shaped.

In the illustrated example, the bearing part 24 preferably has the recess 29 or forms it, as in particular in 3 shown. However, other solutions are also possible here. For example, the recess 29 could also be arranged or formed at another point of the connecting part 20, on the conveyor device 4, in particular its conveyor housing 4A, and/or on the outer housing 14, in particular on the lower housing part 14B.

The recess 29 is preferably designed to correspond to the blocking element 28 . The recess 29 particularly preferably extends through the bearing part 24 and/or transversely, in particular perpendicularly, to the pivot axis S and/or horizontally or in the radial direction in the position of use.

In the locked position, the locking element 28 preferably extends in the radial direction or horizontally in the position of use into the recess 29, particularly preferably radially outwards or away from the longitudinal axis L and/or radially to the pivot axis S.

Solutions are also possible in which the actuating lever 21, in particular the lever arm 23, has the recess 29 and a corresponding locking element 28 on the connecting part 20, the bearing part 24, the conveyor device 4, in particular the conveyor housing 4A, or the outer housing 14, in particular the lower housing part 14B, is arranged or formed. The positive connection is thus formed in particular between the actuating lever 21 and another component of the dispensing device 2, preferably the bearing part 24, in the blocked position or the blocked state.

The blocking device 27, in particular the form fit or the engagement of the blocking element 28 in the recess 29 in the blocking state, preferably blocks or blocks an actuation or pivoting of the actuating lever 21.

Figure 2B and Figure 6B show the actuating lever 21 or the blocking device 27 in the unlocked position or the actuating position in which actuation of the actuating lever 21 or the conveyor device 4 is possible or released. In particular, the actuating lever 21 and/or the blocking device 27 is unlocked and/or the positive locking formed in the blocked position or in the blocked state is canceled or dissolved. Accordingly, the dispenser 1 or the dispensing device 2 is preferably in an unlocked state.

The blocking element 28 is preferably free in the operating position or is not (or no longer) engaged. In particular, the blocking element 28 is not (no longer) in engagement with the recess 29 and/or is (completely) arranged outside of the recess 29, particularly preferably in such a way that pivoting of the actuating lever 21, in particular together with the blocking element 28, is possible or enabled is.

To unlock or to assume the operating position, the operating lever 21 is preferably (manually) displaceable. The actuating lever 21 or the blocking element 28 can thus preferably be shifted or moved from the blocking position into the actuating position.

By moving the actuating lever 21, the blocking element 28 is preferably pushed out of the recess 29 and/or the positive locking of the blocking device 27 is released.

Particularly preferably, the actuating lever 21 can be displaced or pressed linearly and/or in the radial direction, in particular inwards or in the direction of the longitudinal axis L, the bearing part 24 and/or the pivot bearing or pivot axis S.

To move or shift the actuating lever 21 from the blocked position into the actuating position, the actuating section 22 can be moved or pressed, preferably in the direction of the longitudinal axis L, the bearing part 24, the pivot bearing or pivot axis S, the conveyor device 4 and/or the outer housing 14.

The actuating section 22 is preferably also arranged completely outside of the outer housing 14 in the actuating position. The distance between the outer housing 14, in particular the lower housing part 14B, and the actuating section 22 is preferably smaller in the actuating position than in the locked position.

The lever arm 23 can preferably be pressed (further) into the outer housing 14 and/or the conveyor device 4, in particular the conveyor housing 4A. In particular, the lever arm 23 is in the actuated position to a greater extent inside the outer housing 14 or the conveyor housing 4A than in the locked position. The locking element 28, which is preferably formed in one piece with the lever arm 23, is preferably displaced accordingly, in particular in the direction of the longitudinal axis L.

Solutions are also possible in which the actuating lever 21 is brought from the blocking position into the actuating position by a different movement. For example, the actuating lever 21, in particular the lever arm 23, could be partially pulled out in order to move from the blocking position to the actuating position and/or to release the positive locking of the blocking device 27, in particular to pull the blocking element 28 out of the recess 29.

Preferably, the dispensing device 2 or the actuating lever 21 or the blocking device 27 can be blocked again after unlocking or can be blocked again or can be moved (again) from the actuating position into the blocked position. In particular, the blocking effected by the blocking device 27 or the form fit can be restored and/or the blocking element 28 can be engaged (again), in particular with the recess 29.

The actuating lever 21 is particularly preferably linearly displaceable in the opposite direction than when unlocking, in order to (again) block the dispensing device 2 or the actuating lever 21 . Particularly preferably, the actuating lever 21, in particular the lever arm 23, can be partially pulled out of the outer housing 14 and/or the conveyor housing 4A and/or moved away from the longitudinal axis L in the radial direction in order to (again) assume the locked position.

However, other solutions are also possible here, especially where unlocking is irreversible. For example, the actuation lever 21 could latch in the actuation position in an undetachable manner when it is unlocked, or the like.

The bearing part 24 and/or the bearing section(s) 26 are/is preferably designed to movably hold or mount the actuating lever 21, in particular the lever arm 23, in particular in such a way that it can be slid from the blocked position into the actuating position is, particularly preferably, if necessary, back again from the operating position to the locked position.

As already mentioned above, the bearing part 24 preferably has one or more bearing elements 25, in the example shown two bearing elements 25 arranged on opposite sides, in particular bearing journals. The actuating lever 21, in particular the lever arm 23, preferably has corresponding bearing sections 26, into which the bearing elements 25 engage for storage, such as in particular in the Figures 6A to 6C shown.

The displaceability of the actuating lever 21 is preferably realized by the bearing sections 26 . In particular, the bearing sections 26 are designed in such a way that they enable the actuating lever 21 to be displaced. For example, the bearing sections 26 could be in the form of elongated holes formed in the lever arm 23, in which the bearing elements 25 of the bearing part 24 are held or mounted in a longitudinally displaceable manner.

The actuating lever 21 and the bearing part 24 are preferably positively connected to one another, in particular latched or latchable, in the blocking position and/or the actuating position, particularly preferably both in the blocking position and the actuating position. In particular, the (respective) bearing elements 25 are locked or can be locked in the corresponding (respective) bearing sections 26 .

A particularly preferred embodiment of the displaceable bearing is described below using the example of a bearing element 25 and a bearing section 26 . If the bearing, as in the example shown, has a further bearing element 25 and/or a further bearing section 26, the explanations preferably apply accordingly.

The bearing section 26 particularly preferably has a first section 26A and a second section 26B.

In the blocking position, the bearing element 25 is preferably held or mounted, in particular in a latching manner, in the first partial section 26A, as in particular in Figure 6A shown.

Preferably, the bearing element 25 is held or mounted in the operating position, in particular in a latching manner, in the second partial section 26B, as in particular in Figure 6B shown.

The pivot axis S preferably runs through the first section 26A in the blocking position and/or through the second section 26B in the operating position. Pivoting of the actuating lever 21 is preferably only possible if the pivot axis S runs through both the bearing element 25 and the section 26B.

When the operating lever 21 is moved, in particular when it is pushed in, or when it is unlocked, the bearing element 25 is preferably pushed out of the first section 26A and/or pushed into the second section 26B. However, this displacement is preferably only relative to the actuating lever 21. In particular, the bearing element 25 is stationary or immovable relative to the bearing part 24, connecting part 20, conveyor housing 4A and/or outer housing 14.

In the illustrated example, the bearing section 26 is preferably designed as a figure eight-shaped recess or the partial sections 26A, 26B as overlapping, circular recesses. However, other solutions are also possible here.

It would also be possible, for example, for a first bearing element 25 to engage in a recess formed by the bearing section 26, in particular a circular one, in the blocking position and for a second bearing element 25 to engage in the actuating position in the same recess. In this case, the first bearing element 25 would be released from engagement with the bearing section 26 during displacement and the second bearing element 25 would then be brought into engagement with the bearing section 26 .

Figure 2C and Figure 6C show the actuating lever 21 in the actuated position or pivoted position. Preferably, the actuating lever 21 is between the in Figure 2B and 6B shown unactuated position or operating position and in Figure 2C and 6C shown actuated position or pivot position, in particular about the pivot axis S, pivotable.

The movement from the operating position into the pivoting position is preferably effected by manual actuation or pivoting of the operating lever 21 by a user (not shown).

The actuating lever 21 or the lever arm 23 preferably has an arm section 23C. In the illustrated example, two arm portions 23C are formed by the respective ends of the legs 23A opposite the actuating portion 22 .

The base 9, in particular the base element 10, preferably forms or has a counter-surface or actuating surface for the actuating lever 21 or lever arm 23 or the arm section(s) 23C. The actuating lever 21 or lever arm 23, in particular the arm section(s) 23C, preferably rests against the base element 10 or the actuating surface formed thereby and/or acts on it, in particular when pivoting from the actuating position into the pivoting position /or exert a power upon it.

By actuating the actuating lever 21 or the actuating section 22, in particular by pivoting from the actuating position to the pivoting position, the bellows 5 is preferably actuated or compressed and/or deformed or moved from the rest position to the compressed position. This takes place in particular in that during the actuation or pivoting movement, the lever arm 23 rotates about the pivot axis S or the bearing part 24, in particular the bearing element(s) 25, so that an end of the lever arm 23 or the arm portion(s) 23C is raised or moved toward the bellows 5.

In particular, an actuation of the actuation lever 21 or a pivoting of the actuation lever 21 from the actuated position into the pivoted position causes the bellows 5 to be compressed and/or the fluid F to be discharged.

The pivot axis S, the bearing part 24, in particular the bearing elements 25, or the actuating lever 21, in particular the bearing sections 26, are/is preferably arranged in such a way that the smallest possible pivot angle leads to the greatest possible stroke of the arm section(s) 23C , and/or that the force acting on the conveying device 4—compared to a force acting on the actuating section 22—is increased.

The pivot axis S or the bearing elements 25 or bearing sections 26 are/is preferably arranged or formed within the outer housing 14 at the greatest possible distance from the axis L or close to the outer housing 14 .

A movement of the actuating lever 21 from the actuated position or pivoting position (back) into the unactuated position or actuating position preferably takes place automatically or no active movement or actuation of the actuating lever 21 is required for this. A movement from the pivoted position to the actuation position can preferably be effected by a user releasing the actuation section 22 .

The expansion of the bellows 5 and/or the movement of the actuating lever 21 from the pivoted position to the actuating position, caused in particular by the expansion, is preferably effected by the (elastic) restoring force which is caused by the previous elastic deformation or compression of the bellows 5 . During the expansion of the bellows 5, the base 9 or the bottom element 10 or the actuating surface formed thereby preferably acts on the actuating lever 21 or lever arm 23 or exerts a force on the actuating lever 21 or lever arm 23, so that the actuating lever 21 is moved or pivoted from the pivoting position to the operating position.

Preferably, the pivoting path of the actuating lever 21 is limited, for example by corresponding stops 23D on the actuating lever 21 or lever arm 23, which in particular Figures 4 and 5 are shown.

In the operating position, the operating lever 21 is preferably supported from below, in particular by supports 35, which are located in particular in 3 and Figures 6A to 6C are shown. Preferably, the pivoting path is limited by the supports 35 when pivoting back.

As already mentioned above, the design of the dispensing device 2 or conveyor device 4 with bellows is merely preferred. Correspondingly, solutions are also possible in which a pivoting of the actuating lever 21 or a lifting of the lever arm 23 or the arm section(s) 23C causes activation of the delivery device 4 or delivery or delivery of the fluid F in a different way.

The dispensing device 2 preferably has a safety device 30 in addition to the blocking device 27 .

The safety device 30 is preferably designed to block unlocking of the dispensing device 2, the actuating lever 21 or the locking device 27 and/or to secure the dispensing device 2, the actuating lever 21 or the locking device 27 against (accidental or undesired) unlocking. in particular to block a shifting of the actuating lever 21 from the blocking position into the actuating position.

The position of the safety device 30 in which unlocking is secured or blocked is referred to below as the safety position. This is particularly in Figure 2A shown.

The dispenser 1 or the dispensing device 2 is preferably both locked by means of the locking device 27 and secured by means of the safety device 30 in the delivery state or before first use.

The securing device 30 preferably has a securing element 31 or is formed by such. The securing element 31 is preferably designed to block unlocking of the dispensing device 2, the actuating lever 21 or the locking device 27 in the securing position, preferably by positive locking. In particular, the securing element 31 or the securing device 30 prevents the positive locking formed by the locking device 27 from being able to be canceled and/or the locking element 28 from being able to be removed or pushed out of the recess 29 .

The blocking element 31 is preferably elongate and/or rod-like.

The securing device 30 or the securing element 31 preferably acts in the securing position between the actuating section 22 and the outer housing 14, in particular the lower housing part 14B and/or the connecting part 20.

In particular, the blocking element 31 is arranged or fixed in the securing position between the actuating section 22 and another part of the dispensing device 2, in particular the outer housing 14 or lower housing part 14B and/or the connecting part 20, so that the actuating lever 21 cannot be moved from the blocked position can be moved out or is secured against unlocking.

In the securing position, the securing device 30 or the securing element 31 preferably extends transversely, in particular perpendicularly, to the actuating section 22 and/or at least essentially parallel to the lever arm 23 and/or in the radial direction.

The securing device 30 or the securing element 31 is particularly preferably arranged or formed between the legs 23A of the lever arm 23 .

The securing device 30 or the securing element 31 is preferably formed in one piece with the actuating section 22 and/or the lever arm 23 or is molded onto it.

Securing device 30 or securing element 31 is particularly preferably materially connected to actuating lever 21 or actuating section 22 and/or lever arm 23 and/or forms part of actuating lever 21.

The securing device 30 or the securing element 31 is particularly preferably arranged or held rigidly or immovably on the actuating lever 21 .

The securing device 30 or the securing element 31 preferably has a contact surface 31A with which the securing device 30 or the securing element 31 can be attached to the outer housing 14, in particular the lower housing part 14B, the connecting part 20 or another (housing) section of the dispensing device 2 , in the secured position or before reaching the unlocked Position or operating position comes to rest. The system preferably blocks or secures a shifting of the actuating lever 21 into the unlocked position or actuating position.

Solutions are also possible in which the safety device 30 or the safety element 31 comes into contact with the actuating lever 21, in particular the actuating section 22, and with the outer housing 14 or the connecting part 20 or another (housing) part of the dispensing device 2 is materially connected. Solutions are also possible in which the safety device 30 or the safety element 31 is clamped in a force-fitting and/or form-fitting manner between the actuating section 22 and a corresponding housing part or is materially connected both to the actuating lever 21 and to a housing part.

To unlock the dispensing device 2, the actuating lever 21 or the blocking device 27, the safety device 30 or the safety element 31 can preferably be moved from the safety position into an unlocked position.

The securing element 31 can preferably be released and/or moved into the unlocked position by applying a force transversely to the main extension direction of the securing element 31 .

In the unlocked position, the locking element 31 is preferably arranged in such a way that the actuating lever 21 can be displaced or the dispensing device 2, the actuating lever 21 or the locking device 27 can be unlocked, in particular without restricting or impeding unlocking by the locking element 31. In the unlocked position the blocking device 27 or the displacement of the actuating lever 21 is preferably released.

The securing device 30 or the securing element 31 can preferably be pressed in and/or folded away or up, in particular transversely to its longitudinal extension and/or in the axial direction.

The securing device 30 or the securing element 31 preferably has one or more predetermined breaking points 32, a connecting piece 33 and/or an actuating element 34.

The actuating element 34 is preferably formed by an elevation or the like, against which a user (not shown) can press in order to press in or actuate the securing element 31 or to unlock it.

When the actuating element 34 is actuated or pressed and/or when the safety device is unlocked, the holder of the safety element 31 preferably breaks at predetermined breaking points 32 provided for this purpose. The predetermined breaking points 32 are in figure 5 shown. In the example shown, these are designed as connecting pieces or arms between the securing element 31 and the actuating lever 21 , in particular the lever arm 23 . However, other solutions are also possible here.

A connecting piece 33 is preferably formed between the actuating section 22 and the securing element 31, via which the securing element 31 can be folded away or folded up, pushed away or pushed up or folded down, in particular by actuating or pressing the actuating element 34, preferably after the Breaking the predetermined breaking points 32. The connecting piece 33 is preferably designed as a film hinge.

Alternatively, the securing device 30 or the securing element 31 can also be (entirely) removable or breakable from the dispensing device 2, in particular the actuating lever 21.

If the safety device 30 or the safety element 31 has been brought out of the safety position, in particular folded away or up, pressed in or removed, the dispensing device 2, the actuating lever 21 or the blocking device 27 is preferably unlocked or not (no longer) blocked. In particular, the contact surface 31A no longer comes into contact. A movement or shifting of the actuating lever 21 from the blocking position into the actuating position is then possible or enabled.

Saving again is preferably not possible. This is achieved in particular in that the securing element 31 breaks irreversibly at the predetermined breaking points 32 . However, other solutions are also possible here. In particular, if the securing element 31 is clamped in the securing position, it would be conceivable to secure the dispensing device 2, the actuating lever 21 or the blocking device 27 by (re)clamping the securing element 31 (again).

The security device 30 or the security element 31 preferably serves as a seal of originality. This is achieved in particular by the fact that it is not possible to secure again or that the securing element 31 breaks irreversibly at the predetermined breaking points 32 . A user can therefore look at the position of the safety device 30 or the safety element 31, in particular whether it is in the safety position, and/or the state of the safety device 30 or the safety element 31, in particular whether it has already been actuated or removed and/or is broken at the predetermined breaking points 32, see whether the dispenser 1 or the dispensing device 2 is still in the delivery state or has already been used.

The actuating lever 21 is preferably produced in one piece, in particular together with the blocking element 28 and/or the securing element 31, and/or in a common production process, in particular by injection molding.

A preferred method of assembling the dispensing device 2 is described below.

First, the operating lever 21 is placed in the operating position on the connecting part 20 or the bearing part 24, as shown in FIG Figure 6B shown (but with the safety device 30 or the safety element 31 intact and not as in Figure 6B shown folded up).

Then the actuating lever 21 is preferably shifted into the locking position, in particular in such a way that the locking element 28 comes into engagement. This position is in Figure 6A shown. In this position, a gap is preferably formed between the blocking element 31 or its contact surface 31A and the connecting part 20 or the bearing part 24 . The outer housing 14, in particular the lower housing part 14B, is preferably placed on the connecting part 20 from above, in particular connected to it in a latching manner, the gap preferably being filled by the outer housing 14 or the lower housing part 14B, so that the securing element 31 or the Contact surface 31A rests against the outer housing 14 or lower housing part 14B. The operating lever 21 is thus blocked and secured.

In general, the proposed blocking or securing mechanism of the actuating lever 21 can also be implemented without a pump device or pump. For example, the dispenser 1 or container 3 can be under pressure, in particular by means of a propellant gas. In this case, the conveyor 4 is preferably in the form of a valve formed or has a valve. When the delivery device 4 is actuated or the valve is open, the fluid F is preferably released automatically from the dispenser 1 or the delivery device 2 by the increased pressure. By actuating the actuating lever 21, the conveying device 4 can preferably be controlled or activated, in particular the valve can be opened.

The dispenser 1 and/or the dispensing device 2 is particularly preferably recyclable or made (exclusively) from recyclable material or recyclable plastic. In particular, the container 3, the delivery device 4, the delivery housing 4A, the bellows 5, the base 9, the riser 13, the outer housing 14, the outlet channel 15, the connecting part 20, the actuating lever 21, the bearing part 24, the locking device 27 and The blocking element 28, the securing device 30 or the blocking element 31, the closure or dispensing element 36 and/or other components of the dispensing device 2 or the dispenser 1, particularly preferably all components of the dispensing device 2 or the dispenser 1, are made of recyclable material Material or recyclable plastic and / or made of plastic from the family of polyethylenes or formed.

Individual aspects and features of the present invention, in particular of the various embodiments, can be realized and advantageous individually and in any combination.
