Thus, if necessary, an exchange of the container 3 o. The like., And / or refilling the liquid 2 done. Alternatively, the pump 1 may also be a reservoir form for the liquid 2 or the container 3 itself or the pump 1 fixed or inseparable connected to the container 3 or be connectable.

The dispensing device 1 preferably has a first component 4, in particular a lower part, and a second component 5, in particular upper part. The second component 5 is preferably insoluble with the first component 4, liquid-tight and in particular connected gas-tight.

The terms "base" and "top" in the illustration correspond to the preferred arrangement or orientation of the dispenser 1 during normal use. However, this is not necessarily the case. Accordingly, depending on needs, application, training u. Like. The lower part and the upper part are also in any spatial orientation to each other or be aligned.

The first component 4 is preferably rigid and / or integral, in particular made of a suitable, preferably food safe plastic, in particular a polyolefin, such as PP (polypropylene) or PE (polyethylene), sprayed or produced in any other way.

The second component 5 has or forms a flexible, for pumping the liquid 2 elastically deformable portion. 6

In particular, the section 6 has an edge 7 which preferably extends transversely to the main deformation direction of the section 6 (which in FIG Fig. 1 extends substantially downwards) and / or preferably parallel to the main extension plane of the preferably substantially flat second component 5 extends. The deformable portion (pump portion) 6 and its optimum edge 7 are preferably made in one piece from a correspondingly elastically deformable material or plastic, hereinafter also called soft plastic, produced, in particular injected.

In the illustrated example, a preferably rigid or plate-shaped section 14 of the second component 5 is injection-molded onto the section 6 or edge 7 or another connection region or vice versa or otherwise insoluble and in particular liquid-tightly connected thereto. this makes possible a simple production, in particular by so-called "bi-injection", ie in particular injection molding of a further material in the same injection mold, in which a first material is standardized or injected. In particular, such a solid chemical and / or mechanical connection is made possible.

Alternatively or additionally, the Starreabschnitt 14 with the section 6 or edge 7 or other connection area by an undercut, recess, opening, overlap o. The like. Connected or held.

The section 6 is preferably elastically deformable and / or at least substantially hemispherical, dome-like dome-shaped or curved.

In the illustrated embodiment, the inlet valve 9 has a particular elastically deformable or held or flexible, preferably tongue-like valve lugs 11 which an opening 12 - in particular an inlet to the pump chamber 8 - optionally releases or closes and is preferably biased in the closed position. Next, the inlet valve 9 optionally has a particular elastically deformable or held or flexible biasing member 13 which rests on the side facing away from the opening 12 of the valve flap 11 and biases it into the closed position.

The valve flap 11 and the biasing element 13 are arranged on the edge 7 of the section 6, in particular molded or molded or formed integrally therefrom. By means of this lateral arrangement, an at least extensive or even complete decoupling of the inlet valve 9 from a deformation of the section 6 can be achieved. The valve flap 11 and the biasing element 13 can thus move, deform, deflect or the like at least largely independently of the deformation state of the section 6. Thus, a defined closing behavior and / or opening behavior of the intake valve 9 can be achieved.

Fig. 1 shows the section 6 in the non-depressed state, ie with un-actuated pump. The depressed state of the section 6 is indicated by dashed lines.

Fig. 2 shows in a schematic, exploded sectional view of the pump 1. In the unassembled state can be seen how the valve flap 11 and the optional biasing member 13 protrude in the manufacturing state, for example, down from the second component 5 and upper part. When assembling the pump 1 or connection of the second component 5 (upper part) with the first component 4 (lower part) of the valve flap 11 is pressed against the inlet opening 12, whereby the valve flap 11 and the biasing member 13 are elastically deformed and a desired bias against the Inlet opening 12 is reached.

The exhaust valve seat 17 is preferably a tapered portion or the like through an annular shoulder, an axial end of a cylinder bore. educated.

The outlet valve 10 is preferably connected via a connecting channel 18 with the pump chamber 8. In particular, an annular channel 19 is formed around the outlet valve body 15 and / or between the holding portion 16 and the outlet valve seat 17, into which the connecting channel 18 opens.

In the illustrated example, the connecting channel 18 and / or annular channel 19 is preferably formed in or from the second component 5 or upper part, more preferably from the rigid portion 14 and / or by covering the edge 7 and / or other parts or areas from the soft plastic. Particularly preferably, the portion 6 and the outlet valve body 15 and / or the holding portion 16 are integrally and / or made of the same material or formed as a single injection molded part.

In the illustrated example, the edge 7 forms, for example, a partial covering of a groove formed in the rigid portion 14 to form the connecting channel 18. The holding portion 16 is preferably formed directly on the edge 7 or formed integrally therewith. The outlet valve body 15 is preferably formed integrally with the holding portion 16 or formed on this or formed by this.

At a free end of the outlet region 21, a nozzle 22 is preferably formed. The nozzle 22 is realized, in particular, by virtue of the fact that a nozzle insert 23, particularly preferably, is inserted in a clamping manner in the outlet channel 20 forming a corresponding receiving region on the outlet side. However, other constructive solutions are possible. In particular, the optionally provided nozzle 22 can also be attached in any other way to the pump 1 or to the first and / or second component 4, 5 or fluidically connected to the outlet valve 10 or outlet channel 20.

The nozzle 22 is particularly preferably designed for the sprayed dispensing of the liquid 2, in particular such that a spray (not shown) is produced during the dispensing. However, in principle or optionally, the liquid 2 can also be dispensed in the form of a spray jet, such as a flat jet or edge jet.

On the inlet side, the inlet valve 9 or the inlet opening 12 in the illustrated embodiment preferably connects to a connecting piece 24.

In particular, the connecting piece 24 is integrally formed or with formed the first component 4.

The pump 1 preferably has an intake line 26, here a hose or the like. to be able to suck liquid 2 from the container 3. The suction line 26 or the hose is preferably attached to the connecting piece 24. However, other constructive solutions are possible here.

The upper part and the lower part or the components 5 and 4 are particularly preferably connected by ultrasonic welding, and / or in any other way such that the pump chamber 8 and the fluidic connection of the exhaust valve 10 are liquid-tight and also sufficiently gas-tight.

In the illustrated example, the pump chamber 8 connects directly to the intake valve 9. This is preferred to minimize the dead volume. However, other constructive solutions are possible here. For example, between the inlet valve 9 and the pump chamber 8, a connecting channel or the like. be arranged.

The pump 1 or the first component 4 or lower part preferably has a connection device 27 for the container 3. Particularly preferably, the pump 1 or the connecting device 27 is designed such that the container 3 latching and / or screwed to the pump 1 and the lower part 4 is connectable. In particular, the container 3 can be clamped, positively and / or frictionally connected to the pump 1 or the connecting device 27.

The connecting device 27 is preferably formed such that a thickened and / or undercut edge or bead 28 or more axially behind one another arranged beads of the container 3 are clamping and / or latching and / or positively received or retainer. In the illustrated embodiment, the connecting device 27 preferably has an outer cylindrical section 29 and optimally at least one holding region 30 radially spaced within the cylindrical section 29, so that the container with a connecting piece or its edge / bead 28 fits into the intermediate section between the cylindrical section 29 and the holding region 30 formed annulus is insertable.

Particularly preferred here is at least one inwardly facing projection on the cylinder portion 29 on the one hand against at least one formed on the holding portion 30, outwardly projecting projection 31 on the other hand axially offset. In the illustrated example, the projection 31 on the holding portion 30 is preferably by a circumferential bead or the like. educated.

In the illustrated example, the holding region 30 is preferably also cylindrical or circumferential. However, other constructive solutions are possible here.

Fig. 1 preferably has an actuating element 32, which is here in particular as a lever (often referred to as a trigger) is formed. The actuator 32 is preferably manually operable to deform the fluid pumping section 6. In particular, the actuating element 32 can be depressurized and / or pivoted for this purpose. Particularly preferably, the actuating element 32 for actuating the pump 1 or for pumping about a fixed pivot axis 33 is pivotally mounted in Fig. 1 is indicated schematically and extends in the present representation perpendicular to the plane of the drawing. However, other constructive solutions are possible.

The actuator 32 preferably acts directly on the section 6 to deform it to pump liquid 2. In the illustrated example, the actuating element 32 has a first actuating portion 34, which is designed in particular as a projection or elevation, preferably rounded and / or projecting towards the portion 6. The first actuating portion 34 preferably abuts directly on the portion 6 to (further) deform the portion 6 upon actuation of the actuating element 32.

It should be noted that Fig. 1 the pump 1 in the non-actuated state, ie when not actuated or not depressed actuator 32 shows. The actuator 32 is thus here in its upper position. In the illustrated example, the section 6 is preferably already deformed or pressed in this non-actuated state by the first actuating section 34, So in particular to the bottom portion 25 of the pump chamber 8 back. As a result, the preferred bias of section 6 is reached in the unactuated position and in the unactuated position of the pump 1. In particular, it is achieved by the elastic restoring forces and the bias of section 6 that a separate return means, such as a return spring, can be omitted for the return element 32. In the illustrated example, therefore, the provision of the actuating element 32 and its elastic bias in the in Fig. 1 shown unactuated position preferably exclusively achieved by the restoring forces of the section 6.

The actuator 32 is for actuating, starting from the in Fig. 1 shown depressible position. This operation is preferably done manually. For this purpose, the actuating element 32 has, in particular, a handle or a support region 35, on which a user not shown, in particular with one finger or several fingers, can act for actuating or pivoting the actuating element 32.

The handle or the support region 35 is preferably formed integrally with the actuating element 32 or formed by this. However, other constructive solutions are possible.

The actuating element 32 preferably surrounds or surrounds the outlet region 21 or the nozzle 22 of the pump 1. In particular, the actuating element 32 has an opening 36 through which the outlet region 21 or the nozzle 22 or an outlet of the pump 1 extends. Particularly preferably, the opening 36 between the support area 35 and an upper end of the pump 1 and the actuating element 32 is arranged. The opening 36 is preferably elongated, slot-like or oval in shape to allow the desired depression or pivoting of the actuating element.

The aperture 36 may also act as a pivoting limit for the actuator 32 at the same time. In the illustrated example, the opening 36 limits the pivoting of the actuating element 32 upwards, so that the actuating element 32 is held or limited in a defined unactuated position, in which the section 6 is already biased elastically. The elastic restoring forces of section 6 would be the actuator 32nd So continue to swing up. The lower in the illustrated embodiment, the lower edge of the opening 36 bounded by contact with the first component 4 and outlet 21 or on another part of the pump 1, a further pivoting of the actuating element 32 upwards.

The pivot axis 33 is preferably arranged on the outlet or outlet area 21 or the nozzle 22 opposite side of the pump 1 and the pump chamber 8.

Preferably, the pivot axis 33 is arranged substantially at the same height or below the outlet region 21 or the nozzle 22 or another outlet of the pump 1.

The actuating element 32 is preferably pivotably supported by the first component 4 or lower part. The actuator 32 is preferably articulated by snapping with the pump 1 and the first component 4.

The actuating element 32 is preferably mounted on two axially spaced bearings - ie along the pivot axis 33 staggered bearings - pivot. This leads to the most stable storage, in particular low material costs.

In the illustrated embodiment, the actuating element 32 preferably has one, in particular two integrally formed bearing sections 37 with bearing eyes 38, which are engageable in particular latching with one or two bearing pins 39 formed on the component 4, in particular by appropriate insertion bevels and / or axial rebound of the bearing sections 37 at Engaging the actuator 32. However, other design solutions are possible here.

The pump 1 preferably has a lock 40 for blocking the actuation of the actuating element 32

The lock 40 preferably has a manually pivotable and / or integrally formed on a housing part or the first component of the pump 1 blocking element 41. The blocking element 41 is in particular via a film hinge 42 with the first Component 4, in particular in the outlet region 21, or in the region of the opening 36 or connected to another part of the pump 1.

Fig. 1 shows the unlocked position. The blocking element 41 is pivoted forward and does not obstruct or block a pivoting of the actuating element 32. In the locked, indicated by dashed lines the blocking element 41 engages - in the illustrated example with its free end - in the opening 36 and at the preferably upper edge, so that the operation or the pivoting of the actuating element 32 from the in Fig. 1 shown unactuated position in a depressed or position or locked down or blocked. However, other constructive solutions are possible here.

It is also possible that the barrier 40 or its blocking element 41 at the same time serves to cover the nozzle 20 or another outlet of the pump 1 in the locked state or effects such.

The barrier 40 or the blocking element 41 may alternatively also act on another area or part of the actuating element 32.

Alternatively, the blocking element 41 can also be mounted on the actuating element 32 and, in the locked state, act on the first component 4 or lower part or another part of the pump 1.

In the non-locked state, the actuating element 32 is preferably manually operable, in particular depressible or pivotable.

Upon actuation, the actuator 32 in the illustrated example, starting from the in Fig. 1 pivoted position shown down, namely about the pivot axis 33 around. In this case, the first actuating section 34 presses on the section 6 and deforms it into the pumping space 8 or toward the first component 4 or bottom section 25. As a result, the volume of the pump chamber 8 is reduced, and liquid 2 located in the pump chamber 8 is displaced from the pump chamber 8 and discharged via the outlet valve 10 and the nozzle 20. In particular, the liquid 2 flows through the connecting channel 18 and the annular channel 19 to the outlet valve 10, which by the (rising) fluid pressure opens automatically. The liquid 2 then continues to flow via the outlet channel 20 to the nozzle 22, via which the liquid 2 is then in particular atomized or sprayed and is particularly preferably dispensed in the form of a spray.

Upon completion of the operation or corresponding drop in the fluid pressure in the pumping chamber 8, the outlet valve 10 preferably closes automatically again, in particular due to corresponding restoring forces, here the holding section 16.

Due to the inherent elasticity or restoring force of the section 6 takes place after releasing the actuating element 32, a preferably automatic resetting in the in Fig. 1 shown starting position, wherein new liquid 2 is received via the inlet valve 9 in the pump chamber 8, in particular sucked. The opening of the inlet valve 9 during the reset is preferably carried out automatically due to the pressure prevailing in the pump chamber 8 negative pressure. The suction of the liquid 2 from the container 3 takes place here in particular via the suction line 26 and the connection supports 24th

When opening the intake valve 9, the biasing member 32 slides on the valve flap 11 from. The valve flap 11 rises from the inlet port 12 to release it.

After completion of the intake stroke or provision of Section 6 in the in Fig. 1 shown starting position, the suction of liquid 2 from the container 3 is completed. The inlet valve 9 then closes again preferably automatically. The closing of the valve flap 11 by elastic return forces or corresponding bias in its closed position is particularly preferably supported by the prestressed in the closed position or acting on the valve flap 11, but only optionally provided biasing member 13.

In order to facilitate a venting of the pump 1 or the pump chamber 8 and / or to better channel the flow of the liquid 2, in particular at higher viscosity, and / or to facilitate the return of the section 6 from the position pressed onto the bottom section 25, For example, the bottom portion 25 preferably has a channel 43, as in the schematic sectional view of the lower component 4 or lower part according to Fig. 4 indicated schematically. The channel 43 thus preferably forms a ventilation channel. In particular, the channel 43 extends at least substantially in the outlet direction and / or in the direction of flow through the pumping chamber 8 with liquid 2.

The pump 1 has an at least substantially or substantially closed outer housing or an at least substantially smooth or closed outer contour. The outer contour or the outer housing is preferably formed by the actuating element 32 with.

In particular, the actuating element 32 forms an upper cover or an upper housing region or the upper end of the pump 1.

The pump 1 or the first component or lower part 4 preferably forms a housing, in particular outer housing of the pump 1, and / or preferably has two opposite or spaced side panels 44, in particular at the upper or free end of the pump 1, which partially surrounds the actuating element 32 and / or laterally cover and / or form an at least substantially closed outer housing of the pump 1 and / or an upper cover of the pump 1 with the actuating element 32. Particularly preferably, the actuating element 32 is at least movable with a lower side or edge region between the two side panels 44.

However, other constructive solutions are possible. For example, the actuating element 32 can also cover the side panels 44 and / or the other outer housing of the pump 1 from above and / or laterally.

The pump 1 preferably has a ventilation valve 45 for the container 3. The vent valve 45 is preferably formed by the first and / or second component 4, 5.

The vent valve 45 preferably has a movable vent valve body 46 and optionally an associated holding portion 47. Particularly preferably, the holding portion 47 keeps the ventilation valve body 46 movable and / or biased in a closed position against a vent valve seat 48.

The ventilation valve body 46 and the optional holding section 47 are preferably formed by the second component 5 or upper part, in particular made of the soft plastic and / or formed integrally with the section 6.

The preferably bolt-shaped, cylindrical or elongated ventilation valve body has in the illustrated embodiment particularly preferably an elongated or hollow cylindrical shell 49 made of soft plastic and a core 50 made of another material, for example, the material of the rigid portion 14. However, other constructive solutions are possible here.

The vent valve body 46 is preferably seated with a free or circumferential edge of the relatively soft or deformable material or shell 49 on the associated vent valve seat 48.

The vent valve seat 48 is preferably formed in the first component or lower part 4 and / or at least substantially hollow cylindrical.

By correspondingly substantially axial displacement of the ventilation valve body 46, the ventilation valve 45 can be opened and closed, so that a connection of the container 3 or the interior (gas space) of the container 3 with the atmosphere can be opened and closed accordingly.

The vent valve 45 is preferably biased into its closed position or closes automatically, in particular due to the elastically deformable and in particular in the assembled state already deformed holding portion 47. However, other constructive solutions are possible.

The vent valve 45 is preferably forcibly opened upon deformation of the section 6 or actuation of the pump 1 or upon actuation of the actuating element 32. Particularly preferably, the actuating element 32 automatically opens the venting valve 45 when actuated, in particular by a second actuating section 51 of the actuating element 32, for example pushes the vent valve body 46 upon actuation of the actuator 32 in the open position or pushes.

The forced opening of the venting element 45 leads to the advantage that a defined opening and closing can be achieved. In particular, a pressure loss is avoided when sucking liquid 2 from the container 3, which could arise from the fact that in the container 3 nachströmende air must first open a valve. Accordingly, such a rapid return of the section 6 is supported in the unfounded starting position during suction.

The proposed pump 1 preferably has three valves, so the inlet valve 9, the outlet valve 10 and the vent valve 45, which are preferably all formed by the upper part and / or lower part.

The pump 1 is preferably made exclusively of plastic, in particular at least substantially (with the exception of the suction line 26) of injection molded parts.

The pump 1 is preferably constructed of less than ten, in particular of the highest five components, in particular in the illustration only from the actuator 32, the lower part 4 for mounting the actuator 32, the section 6 forming the upper part 5, the nozzle insert 21 and / or Suction line 26.

The rigid portion 14 is preferably made of the same material or a similar material as the lower part 4.

The soft plastic which forms the section 6 and in particular also the edge 7, the outlet valve body 15, the holding section 16, the valve flap 11, the biasing element 13, the holding section 47 and / or the sheath 49, most preferably by integral formation and / or one-piece injection, is preferably a thermoplastic silicone or other suitable material that can be firmly and / or tightly connected in particular by bi-injection with the rigid portion 14.

Individual features and aspects of the described pump or the present invention can also be realized independently of each other and / or in any desired combination.
