Description

Dispensing device

The invention relates to a dispensing device having a pumping device, which has an actuating element with a dispensing opening, wherein the actuating element is slidably disposed opposite to a rotationally fixed in the use position with a pump housing bearing element and the ^{Betätigungsele ¬} ment is arranged rotatably relative to the bearing element.

From EP 0 098 939 A2, a nebulizer or dosing pump of the type described above is already known. Here, a rotatable part is mounted on the pump housing to set different discharge amounts on the metering pump, which has different projections or recesses, so depending on Drehausrichtung the rotatably mounted on the pump housing part relative to a dispensing head different strokes and thus different discharge amounts are adjustable.

From US Pat. No. 6,443,331 B1, a liquid dispenser with an adjustable dispensing volume is also known. In order to adjust the metering volume has a cylinder element has two radially opposite ^¬ oppositely disposed projections which, depending on the associated Drehausrich ^¬ processing of the dispensing beak and thus a so

Apply apron at different heights to protruding shoulders of an inner lining.

Comparable pumping devices are further described e.g. from EP 1 460 001 A1, FR 2 493 515 A, EP 2 21 6261 A1 and WO 210/043317 AI.

Object of the present invention is now to provide a dispensing device of the type mentioned, in which the number of parts is reduced and in which constructive einfa ^¬ che way a different discharge amount can be reliably adjusted.

According to the invention this is achieved in that the bearing element has at least one projecting web with an upper stop edge, wherein a substantially tubular portion of the actuating element on its inner surface on the Circumferentially distributed at least two a different Verschie ^¬ motion defining stages, of which each abhän ^¬ gig of the Drehausrichtung of the actuating element, a step abuts in a lower displacement position on the stop edge.

By the formation of a stop-edge-forming ridge on the bearing element, which bears the actuating element of the Pumpvorrich ^¬ tung, wherein the actuating element has different levels for cooperation with the stop edge of the bearing element on ^¬, can - dependent upon the rotational orientation of the actuating member relative to the bearing element - reliably

different stroke when depressing the actuator can be adjusted. Advantageously, this does not require a separate, annular element vorzus ^¬ see, as is known from the prior art for Hubwegbegrenzung, but a Hubwegverstellung and thus SET ^¬ ment a Dosiermenge can in a simple and efficient manner by the interaction of the actuator and be achieved on the bearing element itself trained steps or stop edges. The bearing element is in this case arranged in a rotationally fixed relative to the pump housing in the position of use, so that the bearing ^¬ element forms a rotationally fixed reference point for rotational orientation of the actuating member. In this case, any connection between the bearing element and the pump housing may be provided, wherein the bearing element and the pump housing may also be formed integrally with each other from ^¬ .

With such a dispensing device, it is basically possible to dispense any flowable substances, such as liquid, gelatinous or porous media, i. By means of the pumping device, any flowable substances can be dispensed in a metered manner from a container with which the pumping device is fluid-conductively connected, such dispensing devices being used in particular in hospitals and the like.

To avoid exposed, projecting edges or steps, which tend to accumulate dirt and which in particular when using the dispenser in hospitals and the like would be disadvantageous, it is advantageous if a lower edge of the tubular portion of the actuating element in an upper rest position, the upper abutment edge of the bearing element covers ^¬ . Thus, exposed to dirt accumulation prone edges can be largely avoided, which is particularly advantageous when using the dispenser in an environment with high hygienic standards, eg in hospitals.

In order to move directly from one dosing to the next during rotation of the actuating element relative to the bearing element, it is advantageous if the steps on the circumference

directly adjoin one another and thus define a staircase-shaped profile. Here, over the step-shaped profile, which is formed on the inside of the tubular portion of the actuating element, several, for example four un ^¬ different, stroke paths are defined, in the case of four different strokes or metering three stages are required because in a metering in which the entire stroke is released, no step is provided. One of these, for example, three stages advantageously forms a blocking position at which the stroke or displacement of the betae ^¬ actuating element relative to the bearing elements is substantially ge ^¬ blocks, so that in the embodiment of three steps then a blocking position and the release of three different Dosage amounts is provided, wherein in the third metering the full displacement of the actuating element is released relative to the bearing element, ie in this metering no displacement path limiting projecting step is provided on the inside of the tubular portion of the actuating element.

In order to make the user easily recognizable that a change between two dosing steps has been completed, it is advantageous if extending in extension of the level jump between two adjacent stages in the direction of displacement guide webs are provided. By providing such running in the direction of displacement guide webs a guide ^¬ web must be overcome by the provided with the stop edge web on Lagerele ^¬ ment upon rotation of the actuating element relative to the bearing element, so that the actuating element and / or elastically deform the bearing element. After the two elements again disengage they snap back to their original position, so that by this snap or latching operation for the user of the dispenser hearing or feel that now another dose level is set.

Furthermore, it is advantageous if a locking step is formed such that when aligned with the stop edge, the actuator is substantially blocked in its upper rest position, so that not only different discharge amounts defi by using provided on the inside of the tubular portion of the actuator stages ^¬ can be, but at the same time - with a corresponding Drehausrichtung of the actuating element relative to the Lagerele ^¬ ment - a blocking position is adjustable, in which a depression of the actuating element and thus a release of the fluid medium is reliably prevented.

Alternatively, the actuating element can also be fixed in a downwardly displaced position, so that advantageously the transport volume of the dispensing device is reduced. For the fixation of the actuating element in a lower rest position ^¬ ment, it is advantageous if in a lower end portion of the Be ^¬ tätigungselements a, preferably circumferential flange-like projection is provided. About this projection, the actuating element can be held in cooperation with a bearing element-side engagement part, for example in a groove or the like, in a lower blocking position.

If a pull tab or a tamper evident ring is provided, which is connected to the bearing element and which blocks the displacement or rotation of the actuating element from an upper or lower rest position, the actuating element can be easily blocked in the blocking rest position by adding a pull tab. wherein the actuating element is mounted displaceable or rotatable only after removal of the pull tab. Thus, with the help of the Abziehla ^¬ cal in a simple way a tampering protection realized. In the case of securing in a lower rest position, a circumferential groove between the ner lower edge of the tamper-evident ring and a lower

Defined flange of the bearing element, in which the projection on the actuating element in the blocking position, that is, if the tamper-evident ring is connected to the bearing element, is added. Of course, all the above-described ^¬ NEN embodiments to tamper with a pull tab or a tamper-evident ring can also independent of a different displacement defining stages depending on the rotational orientation of the actuating member, that are used in any dispensing devices with a bearing element and an actuating element.

In order to prevent canting between the step and stop edge reliable, it is advantageous if two diametrically arranged webs including stop edge and correspondingly diametrically configured Stu ^¬ fen are provided. Accordingly, two diametrically opposite ^¬ lying webs are provided on the bearing element and the

Actuator has per metering stage in each case two diametrically opposite steps, which are in the direction of displacement at the same height. Thus, a symmetrical introduction of force advantageously takes place when the opposing steps emerge on the opposite stop edges, so that a transverse position or tilting of the actuating element during depression is reliably prevented.

With regard to a structurally simple embodiment, it is advantageous if the bearing element is connected by means of a screw connection to the pump housing. Here, in particular, also a lid of a container from which the dispenser to be dispensed fluid medium transported, Zvi ^¬ rule each at a Lagerlement and the pump housing

provided flange, so that in the screw connection of the bearing element and pump housing at the same time a Be ^¬ fastening of the pumping device takes place on the lid.

Of course, bearing element, pump housing and / or cover can also be designed in one piece.

In order to reliably prevent the penetration of dirt to the discharge opening of the pumping device, it is advantageous if the discharge opening of the actuating element is provided with a protective cap. hen, which has a slot-shaped closure opening. Use of such a protecting cap which has a schlitzförmi ^¬ ge closure opening, in particular a cross-slot-shaped Ver ^¬ connection opening can thus also come to be dispensed fluid medium through elastic deformation of the slit-shaped opening in a simple manner from the discharge port through the cap, wherein, after a pumping operation, the slit-shaped Closing opening of the cap automatically closes and thus a penetration of dirt to the discharge opening or the cached in an end portion of the actuator medium is reliably prevented and drying of the cached medium is reliably prevented.

With regard to a constructively simple embodiment for fastening the protective cap in the region of the dispensing opening of the actuating element it is favorable if the protective cap has a circumferential bead which is positioned ^¬ taken in an arranged adjacent the off ^¬ transfer opening detent groove of the operating member.

In order to form the protective cap with a slot-shaped closure opening, which on the one hand can be easily penetrated by the fluid medium, but on the other hand realizes a dirt-repellent closure in the closed position, it is advantageous if the protective cap made of egg ^¬ nem thermoplastic elastomer (TPE) , preferably of a thermoplastic vulcanizate (TPV), in particular of ethylene-propylene-diene rubber particles (EPDM) in a matrix of polypropylene, or silicone.

With regard to the design of the pumping device, it is advantageous in connection with the metered delivery of the fluid medium, when the actuating element with a piston rod

is connected, which is moved with the actuating element, preferably against the restoring force of an elastic spring element, wherein in the actuating element a Ventilele ^¬ ment is added and the piston rod is slidably received in the pump housing, which at one end with a one-way valve, preferably a ball valve , is provided. Here, in particular also be advantageous herausge ^¬ established when the pump housing is received in a riser sleeve in which a riser pipe is accommodated, which is communicatively connected with the one-way valve.

In such a configuration with a riser sleeve it is furthermore possible that the pumping device is connected to the interior of a container and is connected by means of a lid with the Behäl ^¬ ter. Preferably, in the container a slidably mounted, with the climbing sleeve and the container substantially tightly connected follower cuff is taken, so that the trailing cuff is sucked by the negative pressure generated by the pumping device down and thus over the entire useful life of the dispenser the fluid contained in the container Medium is substantially tightly closed, without large surfaces are exposed and thus it would come in these areas to dehydration of the fluid medium; In addition, this advantageously prevents adhesion of the medium to the container inner wall.

If the trailing sleeve has a, preferably a single, upwardly in the direction of the lid conically widening circumferential sealing lip, the trailing sleeve can be introduced into the container in a simple manner, in particular by machine in the context of As ^¬ semblierung. Of course, such a trailing collar can also be used independently of the steps defining a different displacement path as a function of the rotational orientation of the actuating element, ie in the case of any dispensing devices having a bearing element and an actuating element.

FIGS. 1 to 3 show a dispensing device 1 with a pump device 2, which is connected to a cover 3 of a container 4.

In the container 4, any fluid medium can be accommodated, which can be dispensed by the pumping device 2 from the container 4 in a metered manner. For this purpose, the pumping device 2, an actuating element 5 and an actuating lever, which is designed to be displaceable and rotatable relative to a bearing element 6 designed as a screw cap.

The pumping device 2 has a pump housing 7, in which from the container interior 4 'via a riser 8 after passing through a ball valve 9, the previously recorded in the container interior 4 fluid medium is temporarily stored. When moving the operating member 5 in the direction of 5 '', the Vo ^¬ lumen of the pump housing 7 is reduced through a related with the operating member 5 the piston rod 10, so that the pump ^¬ housing or cylinders 7 cached fluid medium through the valve 10 'passes, and can exit via the output channel 11 and the discharge opening 12 of the actuating element 5. In the position shown in Fig. 1, the actuating element 5 is in an upper rest position, in which the actuating element 5 by means of a coil spring 10 '', which acts between the bearing element 6 and the actuating element 5, after the depression of the actuating element 5 for the purpose of delivery is returned automatically from the fluid medium.

The pump housing 7 and the bearing element 6 have each end ^¬ weils a flange 7 'and 6'. In addition, the bearing element 6 in a lower end portion of an internal thread 6 '' and the pump housing 7 in an upper end portion a korrespondie ^¬ ing external thread 7 '' on. When producing a - in use - non-rotatable screw connection can be made by clamping the lid 3 between the two flanges 6 'and 7' immediately in a simple way a connection of the pumping device 2 with the container 4.

The output port 12 is in this case ge ^¬ protects, with a protective cap 13 which has a slot-shaped, preferably Phillips ^¬ shaped shutter opening fourteenth

The protective cap 13 has an encircling locking bead 15 which adjacent to a corresponding groove-shaped recess 16 of the operating member 5 of the dispensing opening 12 is lockingly placed ^¬ taken, so that the cap can be fixed 13 in a simple manner on the actuating element. 5 The slot-shaped cap 13 which, be ^¬ is preferably made of a thermoplastic vulcanizate, particularly Santoprene (TM) or the like opens automatically, and includes in this case independently, so ^¬ that in the closed position of the slit valve 14, a penetration of dirt to that in the Actuator 5 interposed medium is prevented or drying out of the fluid medium due to exposed surfaces is largely prevented.

Furthermore, in FIGS. 1 and 2, a so-called trailing sleeve 17 can be seen, which bears in a sealing manner on the inside of the cylindrical container 4 and on a riser sleeve 18 enclosing the riser pipe 8. Thus, by the Pumping process inside the container 4 'generated negative pressure, the trailing sleeve 17 moves together with the medium to be conveyed due to the negative pressure down, so that the

Following cuff 17 during the emptying of the container 4 in We ^¬ sentlichen continuously applied to the surface of the dispensed Medi ^¬ ums.

In Figs. 4 and 4a, the actuator 5 is shown in detail he ^¬ clear, in particular, in Fig. 4a is shown that the actuating element 5 'has a tubular section 5 which is pushed into a shifted down discharge position via the bearing element 6 ,

As can be seen in FIGS. 4 to 6, by means of a pull-tab 18, which is fastened to the bearing element 6 by means of thin-walled, easily detachable webs 19, a downward sliding of the actuating element 5 can be prevented. Therefore, if the From ^¬ pull tab 18 is not peeled off from the support member 6, an operation of the operating member 5 is not possible and so ^¬ with apparent to the user that the dispensing device 1 is still unused, that is present in the original state; From the ^¬ pulling flap 18 thus serves as a tamper-evident seal.

In the sectional view of FIG. 4a is further seen that the actuator 5 has a valve seat 20, in which a valve 10 is received, which opens when depressing the actuator 5, whereby the medium to be dispensed can pass into a discharge channel 21. The discharge channel 21 opens into the discharge opening 14. To protect against contamination of the discharge opening 14 - as already explained above - in the region of the discharge opening 14, a protective cap 13 is snapped over a locking bead 15 in a locking groove 16.

In Figs. 7 and 8a to 8c, the dispensing device is shown in different metering position, wherein in each metering a different stroke or displacement for the

Actuator 5 is released, so that the delivery is ^¬ under different volumes adjustable. For setting the different metering stages, only the rotational orientation of the actuating element 5 relative to the bearing element is to be changed. dern.

In the blocking position shown in FIG. 7, the actuating element 5 is aligned in such a way that a step 22 projecting inside the tubular section 5 ', which is located immediately adjacent to a lower edge 23 of the tubular section, is already on an upper stop edge 24 a projecting ridge 25 is present on the bearing element 6, so that the actuating element 5 - even after removal of the in Fig. 7 ge ^¬ showed ^tamper evident ^flap 18, see. Fig. 6 - is substantially immobile. Thus, a movement of the actuating element or a metered delivery of the medium via the dispensing device in this blocking metering position is not possible.

When the operating member 5 relative to the bearing member 6 ver ^¬ rotates, reaches a stage 22 '(see FIG. Also Fig. 11) on the inner surface of the tubular portion 5' in aligned arrangement with the web 25, so that the lifting or displacement is defined in a first metering stage, which corresponds to the distance A (see Fig. 7) between the stop edge 24 on the bearing element 6 (see Fig. 12) and the step 22 'of the actuating element 5 in its (upper) rest position. The steps 22, 22 'and 22''are formed in the embodiment shown by a plurality of juxtaposed ribs, but of course also by a respective projecting plane, which so ^¬ then forms a continuous contact surface for the stop edge 24, are defined.

For dosing a larger discharge amount, the Actuate the ^¬ restriction member 5 relative to the bearing member 6 is further rotated ^¬ the, so that the step 22 '' arrives in alignment with the web 25th Thus, a larger stroke is defined, which corresponds to the distance B (see Fig. 7) between the stop edge 24 on the bearing element 6 (see Fig. 12) and the step 22 '' of the Betätigungsele ^¬ element 5 in its (upper) rest position ,

In a third metering stage is the portion 22 '''arranged in alignment with the web 25 of the bearing member 6, in which the tube-shaped portion 5' of the operating member 5 having no vorsprin ^¬ constricting stage, so that the operating member 5 via the entire stroke C (see Fig. 7) can be pressed down until the lower edge 23 on a connecting flange 6 'of

Bearing element 6 is seated. The different stroke paths are compared in Fig. 7.

As seen in Fig. 10, the actuating member 5 to the different rotational orientation associated markers 26, so that is ersicht ^¬ Lich for the user in a simple manner, whether or not a large or a small discharge amount upon depression of the operating member 5 is released.

In addition, on the inside of the tubular portion 5 '- as shown in particular in Fig. 11 - in the sliding or axial direction 5''of the tubular portion 5' extending guide webs 27 in each case in extension of a level jump between ^¬ two stages 22, 22 ' , 22 '' and the step-free portion 22 ''', so that between each two adjacent guide webs 27 each have a guide is formed in which the web 25 is guided during the displacement of the actuating element 5.

In order to change the metering position accordingly, it is necessary that the web 25 is moved via a guide web 27. For this purpose, an elastic deformation of the tubular portion 5 'and / or the bearing element 6 is required, so that the web 25 snaps into the adjacent guide after overcoming the guide web 27. This snapping operation is audible to the user, so that it is easily recognizable to the user that the dosing position has been changed.

In Figs. 11 and 12 also is seen that two diametrically opposite webs are preferably 25 to corresponding An impact edges ^¬ provided 24; Accordingly, in each case two opposite stages 22, 22 ', 22''or step-free areas 22''' are provided, so that when the steps 22, 22 ', 22''on the stop edges 24, a transverse positions of the actuating element 5 is avoided.

In Fig. 13, an alternative embodiment of a tamper-evident closure instead of the peel or Originalitätsla ^¬ cal 18 is still visible. In this case, a tamper-evident ring 27 is provided, which has a plurality of circumferentially distributed projecting webs 28, which in corresponding groove-shaped Recesses 28 'of the in Fig. 13 only partially shown actuating element 5 are added.

The tamper-evident ring 27 is connected to the bearing element 6 via thin-walled, web-shaped elements 29. Only by turning the actuating element 5 from the locking position, and the associated release of the connection of the webs 28 with the bearing element 6, the actuating element 5 can be released from the Sperrstel ^¬ ment, whereby the tamper evident ring 27 releases from its upper position. After the tamper-evident ring 27 has slid down on the bearing element 6, it is thus apparent to the user that the dispensing device 1 is no longer originally sealed.

In the embodiment according to the invention can therefore on the diametrically opposed web-shaped webs 25 and the staircase-shaped configuration of steps 22, 22 ', 22' 'on the inner surface of the actuating element 5 in a simple way a dosage of the output with the pumping device 2 upon actuation amount be achieved on fluid medium.

As can be seen in FIGS. 14, 14 a and 14 b, alternatively, the actuating element 5 can also be fixed in a downwardly displaced position, so that advantageously the

Transport volume of the dispensing device 1 is reduced.

For the fixation of the operating member 5 in a lower Ru ^¬ operations department preferably a circumferential flange-like projection 30 is in this case provided in a lower end portion of the ^¬ Actuate the restriction member. 5 Via this projection 30, the actuating element 5 can be held in cooperation with a tamper-evident ring 18 'in the lower locking position shown in FIG. Unless pulled from a pull tab 18 '' of the tamper evident ring 18 '(in the arrow direction), the connection between tamper evident ring 18' and bearing element 6, which is realized in the embodiment shown via webs 31, solved, so that the actuating element 5 for use the dispensing device 1 is released. Of course, all the above-described embodiments for tamper-evident protection with a pull tab or a tamper-evident ring Also independent of the different displacement path defining stages depending on the Drehausrichtung of the actuating element, ie in any dispensing devices with a bearing element and an actuator, used who ^¬ .
