Description

liquid dispenser

AREA OF APPLICATION AND PRIOR ART

The invention relates to a dispenser for dispensing pharmaceutical liquids according to the preamble of claim 1.

Generic and inventive dispensers comprise an elongated housing aligned along a central axis. At the distal end of the housing an axially aligned in the direction of the central axis discharge opening is provided, can be discharged through the liquid into the environment, for example as a drop and spray. Such a dispenser further comprises a liquid storage and a control device with a pump or a switching valve, which is connected by a first line to the liquid storage and by a second line to the discharge and by means of which liquid can be passed from the liquid storage to the discharge. The dispenser comprises, for the purpose of actuation, an actuation lever which is provided laterally in a recess of a lateral surface of the housing and which is connected to the control device in such a way that a radial depression of the actuation lever in the direction of the central axis actuates the control device so that fluid is directed to the discharge opening becomes.

Such generic dispensers, which represent the starting point of the invention, are also referred to as side-actuation donors.

The special feature of this generically generous and inventive dispenser is that the operation is done laterally. The at least in the region of the lateral surface substantially rotationally symmetrical or cylindrical housing has for this purpose the said actuating push-button, which can be pressed in the radial direction or with a predominant radial component in the direction of the central axis, thereby to conduct liquid in the direction of the discharge opening. This can happen because the actuating pushbutton displaces the piston of a piston pump or compresses the bellows of a bellows pump or opens a valve, so that liquid which has previously been under pressure can flow in the direction of the discharge opening.

From the field of other pharmaceutical dispensers, the direction of actuation coincides with the discharge direction, designs are already known, leading to a backup of the donor against use by children. This prevents children, especially toddlers, carry out and absorb the pharmaceutical liquid.

TASK AND SOLUTION

The object of the invention is to provide a generic side-Activation dispenser with an effective and structurally simple parental control.

For this purpose, five variants are proposed.

According to a first variant of the invention, the following is proposed: The dispenser comprises a rotary sleeve or sliding sleeve which is open on both sides and which is mounted rotatably or displaceably on the outside of the housing about the central axis. In a locked-rotational position or blocking-sliding position, this sleeve prevents the actuation of the actuating lever and in a release rotational position or release-sliding position, the sleeve allows the radial pressing of the actuating lever.

According to this design, the housing of the dispenser is thus provided completely or almost completely (> 270 °) surrounding the sleeve, which in the case of a rotating sleeve is indeed rotatable about the central axis with respect to the lateral surface of the housing, but is not removable or at least for the purpose of actuation does not have to be accepted. This rotary sleeve is preferably secured in the axial direction of the housing, so that it is finally rotatably movable. The alternatively proposed sliding sleeve is limited in the axial direction relative to the housing movable. It can be designed to be non-rotatable or designed to be displaceable and rotatable relative to the housing.

The rotary sleeve or the sliding sleeve is in the manner of a tube on both sides open at the end, so that it can be pushed in particular from the side of the discharge forth on the housing. It is pushed so far that the distal end of the housing and the discharge opening provided there in the pushed state overhangs the rotary sleeve or sliding sleeve in the axial direction, that protrudes beyond the distal end face of the rotary sleeve or sliding sleeve

Depending on the rotational position of the rotary sleeve or the sliding position of the sliding sleeve of the push-button can be pressed or a press is inhibited and / or blocked. In the blocking rotary position or the locking-sliding position, the operation is not possible, either because the push button is not accessible or because its displacement is mechanically blocked. In the release rotational position or release-sliding position of the actuating handle is accessible and radially displaceable for the purpose of Flüssigkeitsaustrags, so that the hereby coupled valve is opened or the associated pump is actuated.

The sleeve itself is open on both sides and therefore does not cover the discharge cap covering. However, such a donor can additionally have a cap which can be attached to the housing or the rotary sleeve and / or cover the housing and the sleeve in the attached state.

The sleeve may have an actuating recess which is located in the release position on the outside of the actuating handle and provides access to the actuating handle.

In such a design of the sleeve with actuation recess, the sleeve is displaceable between a position (blocking rotary position or blocking sliding position), in which the actuating recess is not arranged over the actuating handle and instead this is concealed, and a position ( Release rotary position or release sliding position), in which the recess provides access to the actuating handle. The sleeve is preferably a peripheral part of the housing, which is designed slimmer in the region of the actuating recess relative to the axial direction or has a recess enclosed by the sleeve, through which the actuating lever in the release position of the sleeve is accessible. An interruption of the rotary sleeve in the region of the actuating recess is possible.

In principle, it may be sufficient to produce the parental control only by moving the sleeve into its locked position after use. It is advantageous, however, if an additional safeguard in this locked position prevents the sleeve from being directly twisted or displaced. This additional assurance can consist in particular in that a housing-side section or the sleeve itself has to be elastically deflected or deformed in order to produce the turnability or displaceability.

On the housing may be provided for this purpose a radially deflectable towards the center axis pawl, by means of which the sleeve is locked in at least one locking position, so that it requires a deflection of the pawl to rotate the sleeve in the release position or to slide. Such a pawl creates an additional obstacle for children. In order to bring the sleeve in its release position, the preferably spring-loaded pawl must first be deflected, so that this then allows the rotation or sliding of the sleeve. The pawl may in particular be formed by a portion of the lateral surface of the housing, which must be pressed radially inward for the purpose of movement of the sleeve. This is a very easy way to manufacture. Already in the production of the plastic component, which forms the lateral surface in the mounted state, the pawl is provided in its blocking position, so that said spring load during operation results from the fact that the pawl for the purpose of movement of the sleeve is pressed radially inwards and the Plastic component is thereby elastically deformed.

The pawl acts in the locked state with the sleeve non-positively or in particular form-fitting together to complicate movement of the sleeve or prevent. In a positive configuration, the pawl engages in the locked state in a recess, opening or the like on the sleeve.

The pawl may be arranged on the housing such that it protrudes in the blocking position in the actuating recess.

The actuation recess thus fulfills two purposes in such a design: On the one hand, it enables the depression of the actuation lever in the release position of the sleeve. On the other hand, it blocks a movement of the sleeve in the blocking position together with the pawl.

The pawl may be fixedly connected to the actuating push-button and, in the blocking position, protrude into a blocking recess in the sleeve which is separate from the actuating recess and which is arranged circumferentially or offset in the axial direction relative to the actuating recess.

In this alternative design forms a portion on the actuating handle itself the pawl and engages in the locked position of the sleeve in a second, separate from the actuating recess locking recess. For release, the actuating lever or the pawl provided on it must thus be pressed somewhat radially. Only then, the sleeve can be rotated or moved so that then an operation is possible. In addition to a design in which the pawl can be firmly connected to the actuating pushbutton, it is also conceivable to provide the pawl on the actuating pushbutton, between the pawl and the surrounding parts of the actuator. However, supply pushers provide an elastic compensation element, so that the displacement of the pawl does not yet mitverlagert the vast majority of the actuating handle, so that there is no discharge when unlocking the sleeve.

The sleeve may have a recess into which the pawl protrudes in the secured state. In such a configuration, it can have an extension which is shaped in such a way that, after the cap has been removed from the housing or the sleeve, it can be introduced into the recess in such a way that the pawl can thereby be deflected and then the sleeve is released into the release position. Position can be moved.

In such a design, a kind of key-lock system is provided. The removable cap has an extension, for example in the form of a slender pin, which is inserted into a corresponding recess of the sleeve to deflect the pawl. This recess has a size and / or a shape that it at least without tools, that is alone with the fingers of a child, not allowed to deflect the pawl.

In the aforementioned designs, it is provided that, in particular, a housing-side pawl is displaceable. Alternatively, the following can be provided:

The sleeve and the housing can with positively cooperating rotational or. Translation locking surfaces are provided, which prevent in the locked position moving the sleeve relative to the housing. The sleeve may be made in such a configuration of an elastically deformable plastic, which allows a deformation, in particular an oval deformation of the sleeve by external application of force through which the locking surfaces can be disengaged, so that subsequently movement of the sleeve in the Release is possible.

In such a design, the sleeve and the housing are matched to one another such that at least in the locked position, a positive inhibition of rotation or a sliding movement is given. The in this case, preferably, the housing completely enclosing sleeve must first be deformed, in particular by a two-sided application of force slightly ova deformed [...] so that the engagement between the locking surfaces on the housing and the sleeve is terminated. Then the sleeve can be moved. In a particular design is also provided in the release position that it is secured by the locking surfaces. Especially advantageous embodiments are those in which the blocking surfaces are formed on radial recesses or elevations on the housing side and sleeve side.

According to a second variant of the invention, the following is proposed: The dispenser comprises a peelable cap which, in the mounted state, covers the discharge opening and can be pulled away from the housing in the direction of the central axis towards the distal end and the discharge opening. The cap and housing have cooperating locating elements which, in an engaged relative position, prevent removal of the cap from the housing and deformation of the cap and / or rotation of the cap about the central axis and / or relative movement of a housing portion of the housing on which the locator is provided , relative to the lateral surface of the housing, are brought into a Freigaberelativstellung in which they do not counteract the removal of the cap.

In such a design of the invention, it is accordingly provided that the discharge opening and preferably also the lateral surface with the actuating push-button are covered by a removable cap which prevents the discharge of liquid and preferably also the actuation of the actuating push-button. This cap is intended to be withdrawn axially in the direction of the distal end of the housing, but can not be withdrawn without prior removal.

The cap and the housing can be provided with positively cooperating fixing elements in the form of translation blocking surfaces which prevent the cap from being axially pulled off the housing when the cap is attached.

In at least one rotational position of the cap relative to the housing, a sufficient distance between a cap inside and the housing can be given in this embodiment in a deformation region of the cap, so that the cap is deformable by radial application of force such that the translation-locking surfaces can be disengaged , so that subsequently a removal of the cap is possible.

This first sub-variant of the second variant of the invention provides that the cap is deformed in a deformation region, in particular force applied on both sides to change the cross-section of the cap in this deformation region, thereby the translation-locking surfaces, which previously counteract a peel except Intervention are brought from each other. For this purpose, the cap and the housing must be matched to one another in such a way that sufficient deformation mung of the cap, in particular offset by 90 ° to the cap-side translation locking surface, in this rotational position is possible.

It is preferred if in at least one rotational position of the cap relative to the housing in the deformation region of the cap is no sufficient distance from the housing, so that the cap is not sufficiently deformable by radial application of force to disengage the translation locking surfaces.

This development provides that not in every rotational position, the cap can be deformed so far in the deformation region that the translation locking surfaces can be disengaged. In at least one rotational position, this is not possible, so that the removal of the cap for a child is difficult. Starting from a relative position between the cap and the housing in this second rotational position, the cap must first be rotated relative to the housing about the central axis in order to permit sufficient deformation only thereafter.

In particular, based on this, it can be provided that the cap and the housing are provided with cooperating rotational locking surfaces which prevent the cap from twisting when the cap is attached, the cap and the housing being designed in such a way that the cap is acted upon by radial application of force to the cap Rotation locking surfaces can be disengaged from each other.

With such a design, a removal of the cap is thus prevented not only in a certain rotational position, wherein the stripping, in particular preferably can not be directly made possible by strong deformation of the cap, but it is also a free rotation of the cap not possible, if not before the rotation-locking surfaces have been brought out of engagement by deformation of the cap.

The thus limiting rotational position is preferably defined by two circumferentially offset from each other arranged cap-side rotation-locking surface. In the intermediate region between these cap-side rotation-blocking surfaces in this case, a receiving area is provided which is provided for receiving a housing-side cam. From this receiving space, the housing-side cam can be moved out only by a rotational movement, which requires the said deformation of the cap for this purpose. However, the cap is preferably not sufficiently strong deformable by radial application of force, as that the housing-side cam from the receiving space could be pulled out axially, as opposed to the opposite the rotation-locking surfaces in the radial direction preferably larger translation locking surfaces.

Instead of the above design with the housing side cam and two cam this cam-side rotation-locking surfaces, also a reversal is possible in which the cam is provided on the cap side and rotationally fixed by two spaced-apart rotational locking surfaces on the housing, by deformation of the cap the rotational locking surfaces are surmountable.

Preferably, at least one rotational blocking surfaces is associated with an oblique face opposite the tangential direction, by means of which the cap can unidirectionally overcome the housing-side rotational blocking surface without radial application of force. This bevel thus makes it possible to rotate the cap in one direction with respect to the housing without having to deform it purposefully. This facilitates the displacement of the above-mentioned cam in the region of the recess between the rotational blocking surfaces. It is both a design conceivable in which only one of the two rotation limiting surfaces bounding the recess is associated with such a slope, so that the cam can engage in the recess in a facilitated only in one direction, as well as a design, each with such a slope to each of Both rotational locking surfaces, so that here in both directions of rotation insertion of the cam in the recess is möglich.An the cap can be provided as kapappenseitigem fixing at least one locking lug, which cooperates with a housing-side locking edge as a housing-side fixing in the engagement relative position. The cap-side locking lug can be deflected radially outwardly in this embodiment to be disengaged from the locking edge and thus brought into the Freigaberelativstellung.

In this sub-variant, a detent is provided as a cap-side fixing, which cooperates with a housing-side locking edge and thus initially prevents the removal of the cap. By deflection to the outside, the locking lug can be disengaged from the locking edge, wherein it is preferred in this second sub-variant, that the cap-side locking lug is deflected isolated without the entire cap cross-section is deformed.

On the cap, a retaining lug may be provided as a fixing. In this embodiment, the housing may have a bayonet ring with a circumferentially extending link, wherein the link in a slot area is sufficiently large to allow insertion of the cap-side retaining lug, and in a holding section with a fixing element provided as a fixing element. provided lungs section, so that the retaining lug is not axially withdrawn from the backdrop when arranged in this holding section. When the cap is attached, the bayonet ring and the cap are rotatable relative to each other about the central axis.

In this further sub-variant of the second variant of the invention, the cap cooperates with cap-side retaining lugs with a bayonet ring, wherein it does not depend on the shape, but on the provided and circumferentially extending scenes in which the retaining lugs are axially inserted. In the insertion area of the scenes, the retaining lugs can be inserted, possibly in slightly bent to the central axis shape. However, if the cap and the bayonet ring are rotated relative to one another around the central axis when the retaining lugs are inserted, the retaining lugs are located in the retaining section of the link in which they are secured against axial pulling out by a bayonet-ring-shaped web or the like which forms the tapered section.

It has been shown that such a bayonet connection is difficult to open by children. This is especially true when both the bayonet ring and the cap are rotatable relative to the lateral surface of the housing. In this case, it requires the relative rotation already both hands and the ability to momentszubeaufschlagen with both hands each of the bayonet ring or the cap can. This does not work with small children's hands.

The bayonet ring may additionally have a recess into which the retaining lug of the cap can engage radially when the retaining lug is in the retaining portion of the gate, so that a relative rotation of the cap relative to the bayonet ring only after opposite radial displacement of the retaining lug out of the recess out possible ist.Die said additional recesses cause the retaining lugs are secured in the retaining portion of the backdrop against a rotational relative rotation with respect to the backdrop. In particular, these recesses may extend radially outward from the gate. The retaining lugs are inserted in such a design in a slightly biased state in the scenes. When twisting the bayonet ring with respect to the cap, they enter the holding section and jump there again slightly radially outwards when these recesses are reached. To solve such a connection, the retaining lugs of the cap must first be pressed radially inward to allow only then rotation and then axial removal of the cap relative to the bayonet ring or from the housing.

According to a third variant of the invention, the following is proposed: The actuating push-button and the housing are provided with cooperating fixing elements which allow the radially acting fixing of the actuating push-button relative to the housing in a fixing position.

In this embodiment of the invention, the child safety is not achieved or not only by the fact that the discharge or the push button for the child are not accessible, but by the immobility of the provided for radial displacement actuating push button relative to the housing.

A child must therefore first understand how it can solve this fixation to effect a discharge.

The fixing elements may be designed to define the actuating push button in the depressed state. The determination in the pressed-in state makes it difficult to overcome the fixation by force. It is more difficult to forcibly pull out a depression in the recess of the lateral surface actuated push-button than to push it.

The fixing elements may be designed for automatic latching, so that a movement of the actuating push-button radially outwards or radially inwardly effects a fixing of the actuating push-button.

The automatic engagement causes this form of backup is not forgotten. Preferably, therefore, not only a discharge is effected by depressing the actuating pushbutton, but at the same time also the secured state is established. In a particular embodiment, it may be provided that a pressure point must be overcome before the automatic engagement, so that a partial stroke for discharging and a full stroke for discharging and fixing the actuating handle are haptically differentiable.

One of the fixing elements, in particular that on the side of the actuating pushbutton, can be displaceable transversely to the radial direction for producing and releasing the fixing position. In this embodiment the fixing element may in particular be provided on a tilting element, which has a release surface for manual application of force, by means of which the tilting element is movable, so that this fixing element is thereby disengageable from the other fixing element, in particular the housing side, can be brought.

The displaceable fixing element is thus displaceable relative to the actuating surface of the actuating pushbutton transversely to the radial direction, for example, parallel to the axial direction of the central axis. The design with the aforementioned tilting element, which has both the fixing element and a release surface, is advantageous. Such a tilting element allows the Kraftbeaufschlagungsrichtung for releasing an opposite displacement of the fixing has the consequence, which then dissolves the fixed state.

In a sub-variant of this third variant it is provided that one of the fixing elements is designed in the manner of a slide, which is displaceable relative to the housing between the fixing position and a release position. This slide and the actuating handle are designed for positive cooperation in the fixing position, which in particular a recess or opening is provided on the actuating lever, engages in the slide in its fixing position and is pulled out of the slide in its release position.

With such a design, two elements displaceable by the user relative to the housing are thus provided, namely, on the one hand, the actuating push-button and, on the other hand, said slide, wherein preferably different apertures are provided in the housing for handling both elements. The slider is independent of the actuating handle displaced and prevented in an end position, the movement, in particular the impressions of the actuating lever.

A child must therefore first shift the slider to then be able to discharge fluid by pressing the actuating handle. The safety against this can be increased by a targeted sluggish slide. Furthermore, the shape of the slider, the housing and / or the actuating handle can be designed such that the slider can be moved only after pressing the same relative to the housing or that the actuating push-button must be pressed slightly to be brought out of engagement only then from the actuating lever can. The displacement movement of the slide for blocking or release of the actuating lever is preferably linearly aligned. However, there are also other possibilities, such as, for example, the displacement of the slider along a circular path. According to a fourth variant of the invention, the following is proposed: Opposite to the recess of the lateral surface, in which the actuating pushbutton is arranged, the housing has at least one opening. The actuating push-button is coupled to at least one extension which is pushed out of the housing when the actuating push-button is pressed in, or at least one locking part which is detachable from the housing or movable relative to the housing is provided, which in a blocking position by means of an extension through the opening protrudes into the housing and prevents depression of the actuating handle.

In this variant, it is provided that the mobility of the actuating lever is influenced by one of the recess of the lateral surface circumferentially opposite opening. Thus, the actuating pushbutton can be provided with an extension which can also be an integral part of the actuating pushbutton and which is pressed on depression of the actuating pushbutton on the opposite side through the opening through to the outside. As a result, a child who generates a counterforce on this opposite side with the second hand would not be able to depress the actuation lever. An adult, on the other hand, could specifically surround the dispenser in such a way that it does not cover the openings and thus does not prevent the exit of the extension.

Alternatively, said locking part may be provided, which protrudes through the openings into the interior of the housing and there prevents the movement of the actuating lever. Only after acceptance or relocation of the blocking part is a depression possible.

Also possible are mixed designs, for example, a blocking part, which covers the openings without interfering with them by means of extensions. The then provided on the side of the actuating handle extensions can not escape due to this locking part and thus prevent actuation.

The said blocking part can only serve the purpose of blocking. However, it could also represent a cap that covers the discharge opening at least partially. The locking member may be formed as a removable locking member and adapted to the housing so that it can be fastened in a radial direction on the housing.

The blocking part may have a shell shape adapted to the outer contour of the housing, which in the fastened state surrounds the housing over an angle of more than 180 ° and which has an inner side on which at least one extension is provided. Such a locking member can be placed radially from the side or pushed axially. As a result, it surrounds the housing with an angle> 180 °, it holds on this and preferably forms a clamping connection with this.

According to a fourth variant of the invention, the following is proposed: The dispenser comprises a receiving sleeve whose inner volume is adapted to the outer shape of the housing such that the housing together with the liquid reservoir is completely receivable therein. The inner wall of the receiving sleeve and the outer surfaces of the housing are matched to one another such that it positively counteracts pulling out of the housing. The receiving sleeve has a lateral recess, through which the housing against the adhesion in the direction of an open end of the receiving sleeve is pushed. Also designs with several such lateral recesses in a lateral surface of the receiving sleeve are conceivable.

In this fourth variant of the invention, the child safety device is produced in that the dispenser is received as a whole in said receiving sleeve, so that it does not provide any protruding from the receiving sleeve parts that allow withdrawal. Instead, the housing must be subjected to a force through the lateral recess in order to push it out at the open end of the receiving sleeve. It has been shown that understanding and overcoming the traction of children is difficult to master.

The receiving sleeve and the housing can be matched to one another such that an insertion of the housing is possible only in a rotational position, are offset in the actuating handle and the recess in the circumferential direction against each other. The receiving sleeve and the housing may alternatively be coordinated with each other so that insertion of the housing is possible only in a rotational position, are arranged coincident in the actuating handle and the recess in the circumferential direction. In a design in which insertion is only possible when the actuating handle and the recess are circumferentially offset from each other, the risk is reduced that the actuating lever is actuated upon pushing out of the housing from the receiving sleeve.

However, it may also be the opposite design of advantage, since it takes a greater skill to accomplish the sliding out of the housing, although through the recess through the actuating handle is accessible and depressible.

DETAILED DESCRIPTION OF THE EMBODIMENTS

1 shows a so-called side-actuation dispenser 10. This has a housing 20 with a discharge assembly 22 and a reservoir 30, which is coupled in the region of a coupling ring 28 of the discharge assembly 22 and comprises a liquid reservoir 32.

The discharge assembly 22 has at the distal end via a discharge opening 24 at the end of an applicator 25 designed as a nose olive and an approximately cylindrical and substantially rotationally symmetrical lateral surface 23 between the nose olive and the coupling ring 28. In the region of this lateral surface 23, for the purpose of handling the Dispenser 10 is encompassed by the user, a recess 26 is provided, in which an actuating handle 50 is arranged. This actuating pushbutton 50 can be pressed in the direction of the arrow 4, this direction enclosing approximately a right angle with the central axis 2 of the dispenser, which coincides with the discharge direction at the discharge opening 24. The object of the invention is to provide a child safety device for a dispenser of the type shown in FIG. 1.

The inner components in the region of the discharge module 22 are explained by way of example with reference to FIG. 2, but are identical for all exemplary embodiments. The liquid reservoir 32 is connected via a line 51 to a pump 54. This pump 54 has a movable cylinder 55 which is depressible together with the actuating pushbutton 50. Furthermore, the pump 54 has a valve assembly 57 which is not described in more detail, which draws liquid through the line 51 at negative pressure in the pumping cylinder 55 and which presses fluid in the direction of a second line 52 in the pumping cylinder 55 in the event of overpressure in the pumping cylinder 55, which in turn with the interposition of an outlet valve 25a to the discharge opening 24 leads.

The first embodiment of FIGS. 2 to 5 for the production of a child safety device has a rotary sleeve 60, which is externally mounted on the lateral surface 23 of the housing 20. By locking oil, it is ensured that this rotary sleeve 60 is only rotatable, but can not be easily removed from the housing 20. The rotary sleeve 60 has an actuating recess 62, which has approximately the size of the outside of the actuating lever 50. In the locked position of Fig. 2 and Fig. 3, this actuation recess 62 is offset by 180 ° relative to the actuating handle 50, so that the actuating handle 50 is covered by the rotary sleeve 60 and is not accessible. A turning of the rotary sleeve 60 is not immediately possible because the lateral surface 23 of the housing 20 is provided in the manner shown in particular in FIG. 2 with a recess acting as a pawl 23 a bulge, which projects into the actuating recess 62. If the dispenser 10 is to be actuated from this state, the pawl 23a must first be pressed in radially inward in the manner illustrated by arrow 3 in FIG. 4. Only then can the rotary sleeve 60 be rotated through 180 ° so that the state of FIG. 5 is established, in which the actuating recess 62 of the rotary sleeve 60 provides access to the actuating pushbutton 50. Based on this condition, the donor can now be used as intended. Subsequently, the actuating sleeve 60 is again rotated by 180 °, so that the held during actuation under tension pawl 23a jumps back into the actuation recess 62.

In the embodiment according to FIGS. 6 and 7, a rotatable rotary sleeve 60 is also provided, which is rotatable relative to a lateral surface 23 and an actuating pushbutton 50 about the central axis 2. These can also be brought into a rotational position in which the actuation recess 62 is not disposed above the actuating pusher 50 and therefore thus prevents actuation.

Deviating from the design of FIGS. 2 to 5, however, the anti-rotation device is realized differently here. On the inside of the rotary sleeve 60 are offset from each other by 180 ° blocking webs 62 provided. Corresponding thereto 20 recesses 33 are provided in the lateral surface 23 of the housing. Both the blocking ribs 63 and the depressions 33 are bounded laterally in the circumferential direction by rotational locking surfaces 34, 64. In the secured state of FIG. 7, rotation of the rotary sleeve 60 is therefore not possible. However, the rotary sleeve 60 is here made of a sufficiently deformable plastic, so that a force in the direction of the arrows 5 is suitable to lift out the contrast by 90 ° offset blocking webs 62 from the respective recesses 33. Subsequently, the desired rotation of the rotary sleeve 60 relative to the lateral surface 23 take place and thus the actuating recess 62 are brought into a rotational position in which it allows the operation of the actuating handle 50.

In the illustrated embodiment, a rotational lock on the blocking webs 63 and the recesses 33 takes place both in the position of the rotary sleeve, in which this covers the actuating lever 50, as well as in that rotational position in which the actuation by the actuating recess 62 is possible.

In a simplified alternative design, however, only one recess 33 and only one blocking web 63 are provided, so that only those rotational position is blocked by these elements, in which the actuating handle 50 is not accessible.

In the embodiment of FIGS. 8 to 11, the dispenser 10 has a cap 80 which can be pushed in the direction of the central axis 2 from the distal end and thus covers the discharge opening 24 as well as the actuating pushbutton 50. The parental control is in this case created by the cap, as shown in Fig. 10, with translational locking surfaces 82 engages behind corresponding translation locking surfaces 36 on the housing 20 of the dispenser. In order to release the thus created connection, the cap 80 must be compressed in the direction of the arrows 5. However, in the orientation of Figs. 8 and 9, the available space 37b between the inside of the cap 80 and the detent leg of the housing on which the translation stop surfaces 36 are provided is not sufficiently large to exclude the translation stop surfaces 36, 82 To interfere with each other. The cap must be rotated 90 ° so that it assumes the state of FIGS. 10 and 11. In this Condition can be achieved by applying force along the arrows 5 sufficient deformation, so that then the cap can be removed.

Starting from the secure state of the cap, this must therefore first be rotated and then compressed so that it can be pulled off. This movement is not possible, at least for toddlers.

In the embodiment of FIGS. 12 to 16 again finds a cap 80 use. This cap 80 has opposing projections 87, at the ends locking lugs 88 are provided. Furthermore, a bayonet ring 40 is provided on the housing 20 of the dispenser. As can be seen from FIG. 13, this bayonet ring has a respective link 42 on both sides, wherein these links each have an insertion region 42a and a holding region 42b. In the holding area 42 b, the scenes are tapered relative to the insertion portion 42 a by a web 44. The cap 80 is placed by the projections 87 are slightly pushed towards each other, so that the locking lugs 88 can dive into the insertion areas 42a. Subsequently, the cap is rotated relative to the bayonet ring 40, so that the state of FIG. 14 and 15 sets. An immediate removal of the cap is no longer possible in this state, since the locking lugs 88 can not escape through the tapered holding portion 42 b of the gate 42. The cap 80 must therefore first be turned back relative to the bayonet ring 40.

A special degree of security results when the holding region 42b is designed in accordance with FIG. 16. Here, an outwardly directed recess 46 is provided in the holding area, in the locking lugs 88 dive radially. Such a secured cap can only be solved when first the extensions 87 are pressed towards each other in the direction of the arrows 5, then the cap 80 is rotated relative to the bayonet ring 40 and only finally deducted from the housing 20.

The bayonet ring 40 may be rotationally fixed to the other housing sections, in particular the lateral surface 23 may be formed. However, instead of the cap 80 or in addition to the cap 80, it may be rotatable about the central axis 2, so that it is particularly difficult for a child to keep the projections 87 pressed while the bayonet ring 40 and the cap 80 are rotated against each other.

In the embodiment of Figs. 17 and 18, the child safety is formed by the actuating handle 50 itself. The actuating pushbutton 50 has a tilting element 59, which is a one-piece part the actuating pushbutton 50 is opposite this, however, about a pivot axis 7 is pivotable. At this tilting element 59, a fixing element 58 is provided, which snaps in the depressed state of the actuating handle 50 behind a corresponding fixing edge 27 of the housing and thus secures the actuating handle in the depressed state. Based on this secure state is only by a taking place in the direction of arrow 8 force application of a release surface 59a of the tilting element 59 to achieve a release that causes the actuating lever 50 automatically jumps into its radially outer end position, from where he pressed again can be. Of course, this design of a child safety device via the design of the actuating handle 50 can be combined with other child-resistant features, as described in this application with regard to a rotating sleeve or a cap. The use of several of the described tilting elements 58 on different sides of the actuating lever is possible.

In the embodiment of FIGS. 19 and 20, an opening 21 is provided on the side of the lateral surface 23 opposite the recess 26 for the actuating pushbutton 50. As can be seen from the sectional view of FIG. 20, the actuating push-button is provided with at least one projection 53 which projects into this opening 21 and is pushed out here in the case of an actuation of the actuating push-button. This makes the handling of a child very difficult, since it can muster the required operating force only by holding opposite to the actuating handle 50. However, it often requires a skill that is often lacking in children to hold it in such a way that nevertheless the extensions 53 can escape out through the openings 21.

A related design is illustrated in Figs. 21-23. Again, openings 21 are provided on the recess 26 opposite side. In addition, however, a securing shell 90 is provided, which is shown separately in Fig. 23. This securing shell 90 has extensions 91 on the inside, which are adapted with respect to the shape of the openings 21 in the housing 20. When the shell 90 is clipped to the housing in the manner shown in FIG. 22, these extensions 91 prevent the actuation trigger 50 from being depressed. For a child, who naturally held the dispenser in the area of the safety cup 90, it is difficult to see why this prevents the depression of the actuating lever 50. In the embodiment of FIGS. 24 and 25, a receiving sleeve 94 adapted to the housing 20 of the dispenser is provided. As can be seen from the figures, this receiving sleeve 94 is made sufficiently large so that the housing 20 can be completely received therein when it is inserted through an open side 94a. The housing 20 is held non-positively in the receiving sleeve, wherein this is made possible by a clamping ring 98 which bears against the outside of the reservoir 30. To use the dispenser, the housing is pushed through side recesses 96 toward the open end 94a and thus released therefrom. Such a movement, in which a pushing out of the housing 20 is provided, has proven to be difficult to realize for children.

FIGS. 26 and 27 show a variant of the dispenser of FIGS. 2 to 5. This dispenser also has a sleeve 60 which is pushed onto the housing 22 and which is limitedly movable with respect to the housing 60, but can not be removed. However, the sleeve 60 of this embodiment is not rotatable, but between the two end positions of Figs. 26 and 27 translationally displaceable.

In the position of FIG. 26, the actuating pushbutton 50 of the dispenser is not accessible, since it is covered by the sliding sleeve 60. The sliding sleeve 60 is not directly movable, since it is locked by the pawl 23 a, which projects into the recess 62 of the sliding sleeve 60.

To use the dispenser, the pawl 23a must first be pressed. Only then is it possible to move the sleeve 60 so that it occupies the position of FIG. 34. In this position, the actuating push-button 50 can now be pressed radially through the recess 62 and a discharge can thus be effected.

28 to 33 show a further embodiment according to the second variant of the invention with a removable by deformation substantially rotationally symmetrical and thereby rotatable cap 80. In Figures 28 and 29, the housing 20 with integrated liquid reservoir 32 and distal discharge port 24 on the one hand and the said cap 80 for repeated removal and placement on the housing 20 on the other hand shown. As in the previous embodiments, the dispenser can be actuated by means of a side actuation lever 50. By pressing liquid is pumped from the liquid reservoir 32 to the discharge port 24.

To achieve a parental control, the housing has two outwardly facing cam 29 on opposite sides, which are covered with the cap 80 thereof. correspondent For this purpose, a coupling structure is provided on the inside of the cap 80, which comprises two axially extending ribs 38 and a holding element 39 which, together with the ribs 38, defines a receiving region 48.

The ribs 38 each have rotational blocking surfaces 38B in the direction of the receiving region 48. On the opposite sides, the ribs 38 are each provided with an outwardly facing bevel 38A, that is, a face opposite the peripheral surface and against the radial direction.

The holding element 39 has a translation-blocking surface 39B pointing upwards. Looking down, it also has a slope 39A, which is however to be regarded as optional.

The receiving area 48 is provided for receiving said cam 29 of the housing 20. The cam 29 is intended to be introduced into this receiving area 48 by the cap 80 is pushed in a relative rotational position in which the cam 29 is not aligned with the coupling structure. Subsequently, the cap 80 is rotated relative to the housing 20 so that it passes into the receiving area 48 via one of the bevels 38A.

In this state, the cap 80 is secured. The rotation blocking surfaces 38B counteract rotational movement together with cam-side rotational blocking surfaces and thus prevent the cam 29 from leaving the receiving space 48 by means of a rotational movement. The holding element 39 prevents a direct removal of the cap 80 by means of its translation blocking surface 36.

The beschriene secured state is illustrated in Figs. 30A and 30B. Here, in particular, it can be seen that the cams 29, together with the translation blocking surface 39B, prevent immediate removal of the cap 80.

In order to be able to remove the cap 80 from this secured state, it is necessary to apply a force, as illustrated by the arrows 5 in FIGS. 31A and 31B. This manual application of force causes an oval deformation of the cap 80 also in the 90 ° offset to the force application arranged coupling structure on the inside of the cap 80. This is pressed outwards, so that the rotation-locking surfaces 38B lose their effect. The cap 80 can now be rotated and then removed. However, the deformation of the cap 80 is insufficient to also disengage the translation locking surface 39A from the cam 29, so that it is hardly possible to peel directly even when deformed. Fig. 31A illustrates this. At most, with a force and a skill that is hardly possible for a child, a direct subtraction is possible.

The above-mentioned slope 39A may, however, together with a corresponding bevel 29A on the cam 29, allow the cap to still be seated directly, ie, in alignment with the cam and the recess. In the course of this deformation is achieved indirectly, which can hardly be achieved by manual radial application of force to the cap.

FIGS. 32 and 33 illustrate a possibility of variation. The cap of Fig. 32 corresponds to the cap described above with two ribs 38 each having a slope 38A. The coupling structure on the cap 80 can therefore be inserted into the receiving space 48 in both directions of rotation.

In contrast, in the embodiment of FIG. 33, the right rib 38 is designed differently. It has no bevel and is preferably also higher in the radial direction than the left rib 38. Thus, the insertion and possibly also the lead out of the cam 29 from the receiving space 48 only in one direction of rotation are possible.

In the present example, the housing 20 has two cams 29 and the cap 80 has correspondingly two coupling structures, which are respectively provided opposite one another. However, other numbers may also be provided in each case and it is not absolutely necessary that the same number of coupling structures on the one hand and cams on the other hand be provided.

The dispenser of Figures 34 and 35 and Figures 36A and 36B is a child safety dispenser that is not realized via a cap but could be additional. In the present case, however, provision is primarily made for the parental control, similar to the design of FIGS. 17 and 18, to be effected by an ability to lock the actuating pushbutton 50. For this purpose, a second recess 66 is provided in the housing 20 in addition to the recess 26 for the actuating pushbutton 50, through which a blocking element 68, which can be displaced orthogonally to the actuating pushbutton, can be subjected to force by means of a force application surface 68A. This blocking element 68 has a distal End 68B, to which a recess 50A is provided correspondingly in a side wall of the operating lever 50. In this, the blocking element 68 can engage.

Figures 36A and 36B show the released and locked state of the blocking element 68.

Starting from the released state of FIG. 36A, the blocking element is displaced upward with respect to the figures, wherein the region of a housing edge is displaced slightly radially by means of a bevel 68C against the force of a spring element 69. Once the distal end 68B is engaged in the recess 50A of the actuating pusher 50, this spring element causes the hooked distal end 68B in this recess 50A to be snapped so that a child-resistant condition is subsequently achieved. In this state, the actuating handle 50 can not be pressed and thus no liquid can be discharged.

In order to return from this state back to the released state, the blocking element must be pressed against the force of the spring element 69, so that said snapping is released. Only then can the blocking element 68 be withdrawn so that it releases the actuating pushbutton 50.

Various modifications are possible to increase child safety. Thus, the distal end 68B may have a hook-like shape that is oriented to the right, unlike the above, so that movement of the blocking element to the released position is only possible once the actuating push-button has been pressed down to a certain extent. Furthermore, the relative mobility of the blocking element 68 relative to the housing can be designed differently. For example, a rotatable or swiveling blocking element is suitable for making the release even more difficult for small children.
