Description

The present invention relates to a lockable actuating device for a dosing system of a container according to the preamble of claim 1.

Commercially available actuating devices, which for example have a nozzle and are arranged above a container, by means of a translational to the medium in the container, such as a gas as a hair spray or a liquid as a disinfectant or a cream as in a body lotion directed downward pressure from the container interior to the outside, are well known in the prior art. However, these devices have no possibility to lock the translationally movable to the container actuating device or pumping device, with the aim that unintentional operation of this device does not result in an output of the medium. Consequently, additional protective caps must be placed on the conventional pumping devices.

Some of these caps can be easily removed from the device, whereby an unwanted slippage of the cap can be done for example during transport of the container with the corresponding device within a piece of luggage.

On the other hand, devices are offered with protective caps, in which the protective caps can be solved by a parental control only by applying a defined peripheral force (for example, by squeezing the thumb and forefinger against the outside of the cap) of the device, which is sometimes very cumbersome and the Use of both hands and a certain muscular strength required.

Accordingly, it is advantageous to use an actuating device for dispensing the medium, which can be locked or locked so that no additional protective cap is needed because in the locked position no actuation of the actuator is possible, whereby no medium is inadvertently discharged from the container can.

Such a lockable actuator, for example, in the DE10002088B4 described which serves for a dispenser of a liquid-containing container. This actuator has a capsule-like body, a raw pipe and a protective cap, wherein the protective cap and the base body each having a circumferentially extending waveform with corresponding troughs or wave heads. The device is in a standby position, the wave heads of the cap in the troughs of the body and the wave heads of the body in the troughs of the cap. Consequently, the shaft heads of the protective cap lie on the shaft heads of the main body when the device is in a locked position in which the device can not be operated. In the blocking position, moreover, the protective cap is arranged on the base body such that the passage opening of the protective cap is not located in front of the discharge opening of the base body, whereby a discharge of the liquid is prevented. This device has a very complex structure, which requires a plurality of differently shaped regions of the protective cap as well as the base body to allow a locking of the protective cap in rotational, as well as in translational direction relative to the base body. Because a locking of the protective cap in a rotational direction relative to the base body can not be guaranteed by the waveform formed. Furthermore, there is the risk of contamination of the relevant shaft areas for locking the device, since these areas are arranged on the outside of the base body. Dirt or damage in these areas can adversely affect the use or the useful life.

US 2002/0096539 A1 discloses a lockable dispensing head for dispensing a medium from a container which has a seal ring attachable to the neck of the container. An additional protective cap is available.

US 2006/0237488 A1 describes a dispensing element which has a closure and fastening element as an integral part of the dispensing head.

DE 2011 992 shows a dispensing cap, which comprises a lower part and an upper part, wherein the lower part can be locked by means of a circular lip on a container.

Accordingly, it is the object of the present invention to provide a lockable actuator available, which is inexpensive to manufacture due to a simple structure and has a long life.

This object is achieved by the present invention according to the features of claim 1. It is shown a lockable actuator for a dosing system of a container containing a creamy, liquid or gaseous medium, wherein the actuating device at least has two mutually translationally and rotationally movable elements and is arranged in the vertical direction substantially above the container, wherein the first element of the at least two elements is a means of the second element of the container in the vertical direction spaced and substantially hollow cylindrical head piece with a top surface which has at least two lateral surfaces which are concentric with each other such that the first inner circumferential surface is at least partially spaced radially from the second outer lateral surface to form a cylinder jacket-like gap, and the second element is an engagement ring which is circumferentially closed Has lateral surface which engages at least partially in the intermediate space.

Such a lockable device allows due to the simple structure of a cost-effective production, wherein the necessary areas for operating the device are integrated into the device structure such that they can not be damaged from the outside. Even soiling can not get into the areas necessary for locking, whereby a long life is possible.

The actuating device according to the invention is preferably applied in a translatory direction above a container containing a medium. This may be a creamy medium, such as a body lotion, a liquid medium, such as a disinfectant, or a gaseous medium, such as a hair spray.

In this case, the term translational direction is understood to mean a substantially vertical orientation insofar as the container has a container opening above the container body. Since the majority of the containers have an opening in the vertical direction for opening the medium, the device according to the invention is therefore preferably also applied to this opening above the container.

However, this does not exclude that the device can also be arranged in the horizontal direction laterally or also in the vertical direction below the container, for example in a container suspended from a suspension device.

The container itself, which may be, for example, a plastic container or a can, has a metering device, through which the medium is transported from the container interior to the outside. Above this metering device, which passes through a container opening to the outside, the device according to the invention is arranged. In this case, a nozzle device of the device according to the invention hits directly on the output of the metering system and preferably absorbs it in itself, so that a distance-free transition from one end region of the metering device to the one initial region of the nozzle device is made possible.

The device according to the invention has two elements that are movable relative to one another in a rotational and in a translatory direction. Preferably, the first member which is a header is twisted with respect to the second member, which is an engagement ring.

The engagement ring is the element which is arranged directly on the container and connected to it in such a way that unintentional detachment of the engagement ring from the container as well as a translatory or rotational movement relative to the container is avoided.

The head piece is the element which is connected to the engagement ring in such a way that it can be moved in translatory and rotational direction with respect to the engagement ring and therefore also with respect to the container. Thus, the head piece can be moved to the locking position or operating position described in detail later. Unintentional lifting of the head piece of the engagement ring is also not possible.

The head piece has a hollow cylindrical shape, which has a cover surface, which preferably has a circular shape in the circumferential direction and a narrow, planar shape in the translational direction, and at least two lateral surfaces.

However, the top surface may also have a domed or structured inner and / or outer surface of any shape, whereby integration of another element in or on the top surface, which comprises, for example, regions of the nozzle device, is also possible.

The lateral surfaces of the head piece are each substantially concentric with each other to the top surface and thus form an inner and an outer lateral surface. Both lateral surfaces have an at least partially mutually different diameter, wherein the inner circumferential surface preferably has a smaller diameter than the outer lateral surface. As a result, a cylinder jacket-like intermediate space is formed, in which at least sections of the lateral surface of the engagement ring engages.

It is also conceivable that the intermediate space does not extend completely in the circumferential direction, but possibly only in a region of 180 °, in which then likewise only a correspondingly reduced region of the lateral surface of the engagement ring or a projection of the lateral surface or the like engages in the intermediate space ,

An inner circumferential surface of the device according to the invention has an outer surface which has at least three arresting segments locking in the translatory and rotational direction, which are arranged as projections directed radially outwards and spaced apart from one another in the circumferential direction of the inner lateral surface.

These projections or locking segments are preferably radially outwardly directed formations of the lateral surface, which consequently have a larger radius than the lateral surface itself, but also an identical wall thickness with the remaining area of the lateral surface.

It is also possible that the locking segments are radially outwardly directed elevations, which have a thicker wall thickness, than the lying between the elevations areas of the lateral surface.

Preferably, the locking segments are arranged in the circumferential direction on the outer surface of the inner circumferential surface such that identical distances are present between the individual locking segments. Accordingly, the preferably three locking segments are distributed uniformly in the circumferential direction over the outer surface.

However, it is also conceivable that only one Arretierungssegment is present, which may have any extension in the circumferential direction. Also, the formation of the inner circumferential surface with two locking segments, which are arranged for example in such a circumferential direction on the lateral surface, that these projections are opposite in the circumferential direction, is possible.

The locking segments are preferably in the radial direction outwardly extending formations or deformations of the inner circumferential surface of the head piece. In this case, these deformations can have an arcuate course which is essentially identical to the lateral surface in the circumferential direction. The start and end regions or the inlet and outlet regions of the deformation preferably have a width over the entire width of the lateral surface, i. in the translational direction from top to bottom and in the radial direction outwardly extending material wall, which arises for example by a deformation or bending process of individual areas of the inner circumferential surface.

If, therefore, one of the locking segments viewed from the center of the head piece directed radially outwards, so the shape of the locking segment appears as a substantially quadrangular radially outwardly directed formation of the inner circumferential surface.

However, this formation may also have further embodiments. Thus, for example, from the same angle from the Arretierungssegment have a round, oval or n-angular shape, whereby the material walls no longer need to extend over the entire width of the inner circumferential surface as previously described.

Although the configuration of the locking segments may have very different shapes, it is preferred that all locking segments arranged in the circumferential direction should have the same shape.

The lateral surface of the engagement ring of the device according to the invention has an inner surface which at least three blocking in translational direction and congruent to the Arretierungssegmenten blocking segments, which as radially outwardly directed and circumferentially of the lateral surface spaced recesses arranged each with at least partially in translational and Rotational direction acting stops are arranged.

The blocking segments, which are depressions or recesses of the lateral surface, therefore have a smaller wall thickness than the remaining regions of the lateral surface.

So that the locking segments can engage in the blocking segments for locking the head piece with respect to the engagement ring, the blocking segments should have substantially the same shape as the locking segments. Preferably, the locking segments and the blocking segments are congruent or congruent, whereby the locking segments can be accurately received by the blocking segments without the locking segments having a translational or rotational direction acting clearance.

The stops of the blocking segments are preferably formed by the material wall of the lateral surface, wherein the recess for forming the blocking segments is designed such that the blocking segments preferably only in one defined area have no wall. This area is located in the translatory direction in the upper region of the recess, whereby an application of the locking segments in translational direction from top to bottom is made possible in the blocking segments.

However, it is also conceivable that the stops are arranged completely around the blocking segments, so that an application of the head piece on the engagement ring in the assembly of both elements is possible only over the areas of the actuating segments.

According to the number of locking segments, it is also possible that only one or two blocking segment (s) are arranged in the circumferential direction on the lateral surface of the engagement ring. However, it is necessary for the functionality of the device that the minimum number of blocking segments corresponds to the number of locking segments, whereby more blocking segments can be arranged as locking segments.

Furthermore, the inner surface of the lateral surface of the engagement ring on at least three non-blocking in the translational direction and congruent to the Arretierungssegmenten actuating segments, which are arranged as radially outwardly directed and circumferentially of the lateral surface spaced recesses arranged with each acting in the rotational direction stops.

These actuating segments are according to the blocking segments depressions or recesses of the lateral surface, which have a smaller wall thickness than the other regions of the lateral surface.

The actuating segments also preferably have a substantially congruent or congruent shape with the locking segments in order to avoid play of the locking segments acting in a rotational direction when engaging in the actuating segments. However, it is also possible for the actuating segments to be larger in width (dimension in the rotational direction) and length (dimension in the translational direction) than the locking segments.

The stops of the actuating segments are preferably arranged in a rotational direction, whereby an undesired movement of the locking segments, which engage in the actuating segments in the rotational direction is avoided.

According to the blocking segments, the stops of the actuating segments are preferably likewise material walls which result from the process of removing a recess from the existing lateral surface. However, in the case of the actuation segments, the removal preferably took place from the end of the lateral surface arranged in the translatory direction at the top to the other end of the lateral surface arranged in the translatory direction at the bottom, whereby a kind of swath is produced.

Nevertheless, it is possible that the actuating devices also have a material wall or stop which is arranged on the upper end of the lateral surface in the translatory direction.

Also conceivable are stops which are formed by projections or elevations or the like.

However, at least one of the segments should not have an upper stop, since over this area the locking segments must engage in the assembly of the head piece on the engagement ring in one of the segments.

Also, the minimum number of operating segments should correspond to the number of locking segments, with additional operating segments can be arranged. Preferably, the locking segments, the actuating segments and the blocking segments are present in equal numbers and have a congruent shape.

If the head piece is applied to the engagement ring, then the locking segments engage in the blocking segments or in the actuating segments of the engagement ring, which is at least partially inserted into the intermediate space between the outer and the inner lateral surface of the head piece.

Once the locking segments engage in the actuating segments, a translational movement of the head piece relative to the engagement ring is feasible.

In other words, due to the lack of a lower stop of the actuating segment in the translatory direction, it is possible to move the head piece with its locking segments by acting on the head piece with, for example, a force applied from above in a translatory direction relative to the engagement ring in the translatory direction. This pressure movement corresponds to an actuation of the device according to the invention for triggering a transport of a medium from the interior of the container to the outside by, for example, a corresponding nozzle device.

Accordingly, the device according to the invention is in an operating position when the locking segments engage in the actuating segments.

However, if the locking segments engage in the blocking segments, a translational movement of the head piece with respect to the engagement ring is not feasible, since the device according to the invention is in a blocking position.

That is, the lower stop in the translatory direction of the blocking segments prevents a translational movement of the head piece and, accordingly, of the locking segments with respect to the engagement ring due to a force applied, for example, in a translatory direction, to the head piece.

The device according to the invention allows a rotational movement or a rotational movement of the head piece and accordingly the locking segments with respect to the engagement ring and accordingly with respect to the blocking and actuating segments.

When a rotational movement is performed, the detent segments first engaged in the actuating segments then engage the blocking segments or the detent segments first engaged in the detent segments, then into the actuating segments.

Accordingly, for example, by a rotational movement of the head piece relative to the engagement ring, the locking segments engaging in the blocking segments (blocking position) are rotated in the direction of rotation either in the clockwise direction or in the opposite direction thereof. For this purpose, the attacks lying in the rotational direction are overcome with a defined force. The locking segments are then moved over a certain area of the inner surface of the lateral surface of the engagement ring until they engage in the actuating segments (actuation position).

During the position change from the blocking position to the operating position, it is possible that the inner annular surface of the head piece is easily deformed (elastic deformation) in the areas of the locking segments at least temporarily, since these areas are moved during the rotational movement over the lateral surface of the engagement ring, which for example, have no recesses. The resulting increased back pressure on the locking segments can result in temporary deformation.

By means of the use of elastic materials, however, these possible deformations can be regressed, since elastic material always has the tendency to return to its original shape after deformation.

In a preferred embodiment, the areas of the lateral surfaces of the engagement ring over which the locking segments are moved have a transition region. This transition region has a smaller wall thickness and consequently a larger radius than the unchanged regions of the lateral surface of the engagement ring. As a result, the locking segments can be moved much more easily from, for example, an actuating segment to a blocking segment, since the transitional regions build up a lower counter-pressure on the locking segments.

However, these transition areas do not necessarily have to be arranged between each blocking and actuating segment. As described above, an unintentional rotation of the head piece with respect to the engagement ring is not possible, since the locking segments within the blocking segments or the actuating segments are blocked by means of stops acting in a rotational direction.

A rotation (rotational movement) of the head piece relative to the engagement ring is preferably possible only by means of a defined applied force.

However, the stops of the blocking and actuating segments can not prevent inadvertent translational movement of the head piece relative to the engagement ring, namely a disassembling movement. Accordingly, additional projections should be arranged within the device according to the invention, which avoid unintentional disassembly of the head piece of the engagement ring and the engagement ring relative to the container.

Thus, a translationally lower portion of the outer surface of the head piece on a radially inwardly directed first projection, which interacts with a second projection of the lateral surface of the engagement ring in the translational direction holds.

Accordingly, an upper region of the lateral surface of the engagement ring in the translatory direction has the second projection directed radially outwards, which interacts with the first projection of the outer lateral surface of the headpiece in the translatory direction.

Both projections can preferably be circumferentially arranged circumferentially or, for example, only partially present, it being important to ensure that the first projection is always arranged in the region of the second projection.

The interaction of both projections is effected by blocking the direction of movement of the other projection, wherein preferably the first projection is blocked by the second projection.

That is to say that the first projection is arranged in the direction of translation behind and / or below the second projection, whereby the translatory movement of the head piece relative to the engagement ring limits the upward translatory movement of the head piece through the arrangement of the second projection. Unintentional disassembly or lifting it head piece of the engagement ring is therefore not possible.

The shape of the first and the second projection may be formed differently, wherein preferably a cross-sectionally oval projection is arranged to ensure assembly of the head piece on the engagement ring without damaging the device according to the invention.

For this, preferably, the second projection in the direction of translation in the upper region of the projection on an inlet slope, whereby the first projection or the outer lateral surface can be performed during the assembly of the head piece on the engagement ring over the second projection problem-free.

During assembly of the head piece on the engagement ring, at least temporary deformation (elastic deformation) can occur at least in the region of the first projection of the outer lateral surface or also in the region of the second projection of the lateral surface of the engagement ring. This is due to a necessary extension of the radius in the region of the first projection of the outer lateral surface or a reduction in the radius of the region of the second projection of the lateral surface of the engagement ring during the assembly process, so that the first projection can be pushed over the second projection in order subsequently to literally snap in the direction of translation after the second projection.

A permanent deformation of the areas can be avoided by the use of elastic material in the areas of the lateral surface.

Likewise, it is necessary to avoid an unintentional translational movement of the engagement ring relative to the container,

For this purpose, the lower in the translational direction of the lateral surface of the engagement ring on a radially inwardly directed third projection, which interacts with a fourth projection of the container, at least in the translational direction.

In this case, the third projection preferably has a ramp-like feed region lying down in the translatory direction, which allows a simple application of the engagement ring to the container. Otherwise, the third projection may have an arbitrary shape in cross-section and be arranged continuously or only in sections in the circumferential direction.

The fourth projection is a part of the container and may be present as a recess or as a peripheral edge or the like.

During assembly of the engagement ring on the container, there may be an expansion of the radius in the region of the third projection of the lateral surface, whereby the lateral surface at least partially and preferably at least only temporarily deformed (elastic deformation) is.

By means of the use of elastic material as a lateral surface these deformations can be regressed.

In a preferred embodiment, the lateral surface of the engagement ring comprises at least two superposed in the translational direction and circumferentially closed lateral surface areas, wherein the translatorily arranged at the top lateral surface area has a smaller radius than the translational direction lower lateral surface area and both lateral surface areas by means in the radial direction extending shoulder are connected.

The shoulder between the two lateral surface areas serves, for example, to limit a movement of the headpiece relative to the engagement ring in the translatory direction by moving the first projection in a translatory direction relative to the engagement ring by actuating (applying a compressive force on the headpiece) of the headpiece the distance between the first and second protrusions increases as the distance between the first protrusion and the shoulder decreases. This movement can be carried out until the first projection hits the shoulder and is blocked by it in its movement.

Accordingly, the shoulder prevents too far insertion of the head piece in the translational direction against the engagement ring and thus accidental damage to the nozzle device or the metering device of the container.

Further advantages, objects and characteristics of the present invention will be explained with reference to the appended drawing, in which an actuating device according to the invention for a dosing system of a container in an operating position and a blocking position and the head piece and the engagement element of the device according to the invention is shown.

The 1 shows a three-dimensional view of the outside of an embodiment of the actuator according to the invention 1 with nozzle device, wherein the actuating device 1 from a head piece 2 and an intervention ring 3 consists. The head piece 2 additionally has an outlet opening 4 for dispensing the medium, wherein the opening is a nozzle 5 has, through which the medium can be issued controlled according to.

The outlet opening 4 is hereby preferably in the radial direction in the outer lateral surface 2a of the head piece 2 arranged.

Furthermore, in translatory direction above the head piece 2 another structural element 6 on the top surface 2c of the head piece 2 arranged, whereby, for example, the concentric center of the head piece 2 can be marked. This will activate the device 1 simplified by the head piece 2 exactly centric by means of a compressive force, which in translatory direction from above on the head piece 2 or the structural element 6 is applied, is applied. Also prevents the structural element 6 by a roughened or textured surface slipping of the user's finger while operating the device 1 , The 2 shows a three-dimensional view of the inside and outside of an embodiment of the actuator according to the invention 1 with nozzle device 7 , The nozzle device 7 in this case comprises an inlet opening 7a , a channel 7b and a nozzle 5 which are in the outlet opening 4 is arranged. The inlet opening 7a is centric on the lower surface of the top surface in translatory direction 2c arranged and has a funnel-shaped area. This funnel-shaped area allows the recording of an output of a metering device of the container.

About the channel 7b becomes the medium from the inlet opening 7a to the outlet opening 4 or the nozzle 5 passed. The channel 7b extends preferably in the radial direction from the inlet opening 7a to the nozzle 5 or outlet opening 4 and preferably has a circular cross-section. However, other embodiments of the channel are also 7b conceivable in that the cross section has an octagonal or oval or another shape. Preferably, a shape of the channel in which no medium can settle, is preferred in order to avoid that deposited in bends and columns media remaining in the nozzle device despite any cleaning operations. This would mean contamination of the nozzle device.

Furthermore, the inner circumferential surface 2 B as well as the outer lateral surface 2a shown. Between the two lateral surfaces 2a . 2 B of the head piece 2 becomes at least an area of the engagement ring 3 added.

The 3 shows a three-dimensional view of the inside and outside of an embodiment of the head piece 2 the actuating device according to the invention 1 , The head piece 2 has an outer circumferential surface 2a and an inner circumferential surface 2 B on, concentric to the top surface 2c and are arranged to each other such that the inner circumferential surface 2 B in the radial direction within the outer lateral surface 2a lies. The radius R2b of the inner lateral surface 2 B is therefore smaller than the radius R2a of the outer surface 2a ,

Furthermore, the inner lateral surface comprises 2 B three formations 22 which extend radially outward and locking segments 22 form, wherein the radius R22 of the locking segments 22 is greater than the radius R2b of the inner circumferential surface 2 B but smaller than the radius R2a of the outer surface 2 B (R2b <R22 <R2a). These locking segments forming radially outwardly extending deformations have a rectangular shape extending circumferentially and over the entire lateral surface width and are evenly distributed in the circumferential direction such that each locking segment is equidistant from the next locking segment.

4 shows a three-dimensional view of the inside and outside of an embodiment of the engagement ring of the actuator according to the invention. The engagement ring 3 consists of two superimposed in the translational direction lateral surface areas 3a . 3b over one shoulder 3c connected to each other.

The inner surface of the lateral surface 3 and preferably the inner surface of the translationally arranged at the top lateral surface region 3b has three blocking segments 33 and three actuation segments 34 on, which are arranged distributed uniformly in the circumferential direction, each with a blocking segment 33 and an actuation segment 34 alternate.

The radius R3a of the lower lateral surface area 3a is preferably greater than the radius R3b of the upper lateral surface area 3b , The radius R33 of the blocking segments 33 is preferably the same size as the radius R34 of the actuating segments 34 and preferably larger than the radius R3b of the upper lateral surface area 3b , Thus, viewed from above, the upper lateral surface area is viewed from the translational direction 3b a smaller circumference than the lower lateral surface area 3a but with both lateral surface areas 3a . 3b are preferably concentric. The form of the two lateral surface areas viewed from above in a translatory direction 2a . 3b is preferably substantially circular, but may also have different embodiments, both lateral surface areas 3a . 3b should have the same shape.

Between the blocking segments 33 and actuation segments 34 are still sections of the inner surface of the lateral surface 3 or the lateral surface area 3b ,

In addition, the second projection 35 on the outer surface of the upper lateral surface area 3b and the third lead 36 on the inner surface of the lower lateral surface area 3b circumferentially arranged circumferentially.

The 5 shows a plan view of the in 4 illustrated embodiment of the Eingriffringes 3 the actuating device according to the invention 1 , whereby the positioning of the blocking elements 33 and actuation segment 34 is illustrated in the circumferential direction.

According to 5 preferably has the upper lateral surface area 3b the blocking 33 and actuation segments 34 each time between a blocking 33 and an actuation segment 34 an overflow area or transition area 37 is arranged, which allows the Arretierungssegmente (not shown here) in a change of the operating segments 34 to the blocking segments 33 or the other way around, triggered by a rotational movement of the head piece (not shown here) opposite the engagement ring, a transition area 37 move, which reduces excessive deformation of the Arretierungssegmente.

Furthermore, the upper lateral surface area 3b additional areas on which this Transition area 37 do not have. In these areas there is no movement of the locking segments from a blocking segment 33 in an actuation segment 34 or the other way around.

Thus, the head piece can only rotate once in each direction with respect to the engagement ring. That is, during a rotary movement of the head piece with respect to the engagement ring 3 counterclockwise, the locking segments, which, for example, in the actuation segments 34 engage in the direction of the blocking segments 33 over the transition area 37 moves until the locking segments in the blocking segments 33 intervention. A further turning in this direction is then no longer possible, because after the blocking segments 33 no other transitional area 37 is arranged.

Consequently, the radius R37 is preferably smaller than the radius R3b of the upper lateral surface area.

Additionally are in 5 attacks 38 . 39 shown which the blocking 33 and / or operating segments 34 in rotational and / or translational direction limit. These attacks 38 . 39 prevent unwanted movement of the locking segments in undefined directions and are, for example, material walls 38 . 39 which by removing the recesses 33 . 34 arise or remain.

6 shows a three-dimensional view of the outside of an embodiment of the actuator according to the invention with nozzle device in the unactuated blocking position. Means on the outer surface of the lower lateral surface area 3a attached labels K1 and K2, the current positioning of the actuator 1 and in particular the head piece 2 opposite the engagement ring 3 be read.

The outlet opening 4 is in accordance with 6 in translatory direction above the marking K1, which makes it clear that the actuator 1 is in a blocking position. This means that the locking segments (not shown here) engage in the blocking segments (not shown here). In this position, the user is not possible by applying a translational direction from the top of the head piece 2 applied pressure force the head piece 2 in translatory direction opposite the engagement ring 3 to move. The device 1 is blocked and no medium can be removed from the inside of a container (not shown here).

7 shows a three-dimensional view of the outside of an embodiment of the actuator according to the invention with nozzle device in the actuated operating position. Opposite the blocking position, as in 6 shown, engage the locking segments (not shown here) in the actuating segments (not shown here), whereby a translational movement of the head piece 2 opposite the engagement ring 3 is possible.

At the in 7 the embodiment shown, the device is in an actuated position. This means that by means of a compressive force, which from translational direction from above on the head piece 2 is applied, has the head piece 2 opposite the engagement ring 3 moved in translational direction down, whereby the first projection (not shown here) of the outer lateral surface 2a of the head piece 2 the shoulder (not shown here) of the engagement ring 3 touched.

The outlet opening 4 is located in this actuation position in the translational direction above the marking K2.

This type of marking presented here is only an example and should not exclude other forms of labeling. For example, the markings themselves may take a different form than those in 6 and 7 shown rectangular configuration (letters, numbers, etc.) or on the outer surface of the upper lateral surface 3b of the engagement ring 3 be arranged.

In 8th is a three-dimensional view of the outside of a container with an embodiment of an actuator according to the invention arranged thereon in the unactuated operating position shown. This is the device 1 in translatory direction above the container 100 , where the engagement ring 3 by means of the third projection (not shown here) in a recess or the like (not shown here) of the container encloses to unintentional release of the device 1 from the container 100 to prevent.

The 9 shows a longitudinal section AA through the in 8th illustrated embodiment of the actuator according to the invention 1 with container 100 , The device located in a non-actuated blocking or actuation position 1 has a first lead 23 on, in a translational direction lower portion of the outer surface 2a of the head piece 2 extends in the radial direction inwards, while a second projection 35 of the engagement ring 3 touched. The second projection 35 is located in a translatory direction in the upper region of the engagement ring 3 or the upper lateral surface area 3b and extends radially outward.

The first advantage 23 and the shoulder 3c of the engagement ring 3 are spaced apart in a non-actuated position of the device.

Furthermore, in 9 a third lead 36 shown translating in a lower region of the engagement ring 3 or the lower lateral surface area 3a is located and extends in the radial direction inwards.

The third lead 36 is with a fourth lead 102 of the container 100 connected so that the device 1 or the engagement ring 3 not unintentionally from the container 100 solve.

In addition, the inner lateral surface is also 2 B shown, the wall thickness may be formed thicker or thinner than the wall thickness of the outer surface 3a ,

Also, the inner lateral surface 3b continue to extend in translational direction down than the outer surface 3a , This has the advantage that the inner surface of the upper lateral surface area 3b directly on the outer surface of the inner lateral surface 2 B is applied. Thus, the head piece 2 to the engagement ring 3 stabilized and the translational movement of the head piece 2 to the engagement ring 3 by means of the inner lateral surface 2 B guided.

The dosing device 101 of the container 100 engages in the nozzle device and in particular in the inlet opening 7a the nozzle device, whereby a gap-free transition is ensured.

10 shows a three-dimensional view of the outside of a container with an embodiment of an actuator according to the invention arranged thereon in the actuated operating position. In this position, the locking segments (not shown here) engage in the actuating segments (not shown here) and translate from above onto the head piece 2 acting pressure force pushes the head piece 2 against the engagement ring 3 or the container 100 , As a result, the nozzle device (not shown here) is likewise pressed against the metering device (not shown here).

In 11 is a longitudinal section BB through the in 10 illustrated embodiment of the actuator according to the invention 1 with container 100 shown. Opposite the in 9 illustrated device 1 in the unactuated position has the first lead 23 moved in translational direction down, causing the distance to the second projection 35 enlarged and the distance to the shoulder 3c has decreased. In a fully executed pushing movement is the first projection 23 even on the shoulder 3c on which the translational movement of the first projection 23 limited to damage the device 1 or the nozzle device 7 or the metering device 101 to avoid.

The inlet opening 7a got along with the headpiece at the same time 2 moved translationally down, causing the output section of the metering device 101 deeper into the interior of the outlet opening 7a was inserted. Due to projections or recesses or elevations extending in the radial direction in the outlet opening, further penetration of the metering device takes place 101 in the inlet opening 7a prevents, whereby at the same time the metering device 101 with a translationally coming from above compressive force, triggered by the translational downward movement of the head piece 2 and therefore the outlet opening 7a , is charged. This triggers a discharge of the medium from the inside of the container 100 to the outside, which through the metering device 101 in the inlet opening 7a the nozzle device 7 transported and through the channel (not shown here) to the outlet opening (not shown here) or nozzle (not shown here) is promoted.

All disclosed in the application documents features are claimed as essential to the invention, provided they are new individually or in combination over the prior art.
