Definitions

  • 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 there is provided a discharge opening which is axially aligned in the direction of the central axis and through which liquid can be discharged into the environment, for example as a droplet and spray jet.
  • a dispenser further comprises a liquid reservoir and a control device with a pump or a switching valve, which is connected to the liquid reservoir by a first line and to the discharge opening by a second line and by means of which liquid can be conducted from the liquid reservoir to the discharge opening.
  • the dispenser For the purpose of actuation, the dispenser comprises an actuating pusher which is provided laterally in a recess in a lateral surface of the housing and which is connected to the control device in such a way that a radial depression of the actuating pusher in the direction of the central axis actuates the control device so that liquid is directed to the discharge opening will.
  • Such generic dispensers which represent the starting point of the invention, are also referred to as side actuation dispensers.
  • the housing which is essentially rotationally symmetrical or cylindrical at least in the area of the lateral surface, has the aforementioned actuating lever, which can be pressed in the radial direction or with a predominantly radial component in the direction of the central axis in order to direct liquid in the direction of the discharge opening.
  • the actuating pusher shifts the piston of a piston pump or compresses the bellows of a bellows pump or opens a valve so that previously pressurized liquid can flow in the direction of the discharge opening.
  • dispensers are known in various designs. These dispensers are designed as side actuation dispensers and some are provided with protective caps.
  • the object of the invention is to provide a generic side actuation dispenser with an effective and structurally simple child safety device.
  • the dispenser comprises a removable cap which, when fitted, covers the discharge opening and can be pulled off the housing in the direction of the central axis towards the distal end and the discharge opening.
  • the cap and the housing have interacting fixing elements that prevent the cap from being pulled off the housing in a relative engagement position and by deforming the cap and / or rotating the cap about the central axis and / or relative movement of a housing section of the housing on which the fixing element is provided , opposite the outer surface of the housing, can be brought into a relative release position in which they do not counteract the removal of the cap.
  • the discharge opening and preferably also the lateral surface with the actuating pushbutton are covered by a removable cap which prevents the discharge of liquid and preferably also the actuation of the actuating pushbutton.
  • This cap is intended to be pulled off in the axial direction in the direction of the distal end of the housing, but cannot be pulled off without prior unlocking.
  • the cap and the housing can be provided with positively interacting fixing elements in the form of translation blocking surfaces which prevent the cap from being pulled off axially from the housing when the cap is in place.
  • This first sub-variant of the invention provides that the cap is deformed in a deformation area, in particular is acted upon by force on both sides, in order to change the cross section of the cap in this deformation area, thereby disengaging the translation blocking surfaces, which previously counteract a pull-off will.
  • the cap and the housing must be matched to one another in such a way that sufficient deformation of the cap, in particular offset by 90 ° with respect to the translational blocking surface on the cap side, is possible in this rotational position.
  • the cap cannot be deformed so far in the deformation area in every rotational position that the translation blocking surfaces can be disengaged. This is not possible in at least one rotational position, so that it is more difficult for a child to remove the cap.
  • the cap Starting from a relative position between the cap and the housing in this second rotational position, the cap must first be rotated about the central axis with respect to the housing, in order to allow sufficient deformation only afterwards.
  • the cap and the housing are provided with interacting rotational blocking surfaces that prevent the cap from rotating when the cap is in place Rotational locking surfaces can be brought out of engagement with each other.
  • the cap is not only prevented from being pulled off in a certain rotational position, with the cap not being able to be pulled off directly, in particular, preferably also by strong deformation of the cap, but free rotation of the cap is also not possible, if not beforehand the rotation locking surfaces have been disengaged from one another by deformation of the cap.
  • the rotational position limiting in this way is preferably defined by two rotation blocking surfaces on the cap side which are offset from one another in the circumferential direction.
  • a receiving area is provided in the intermediate area between these cap-side rotation blocking surfaces, which is provided for receiving a cam on the housing side.
  • the cam on the housing side can only be moved out of this receiving space by a rotary movement, which requires the aforementioned deformation of the cap.
  • the cap is preferably not sufficiently deformed by the application of radial force to allow the housing-side cam to be pulled axially directly out of the receiving space, since this is opposed by the translation-blocking surfaces, which are preferably larger in the radial direction than the rotation-blocking surfaces.
  • At least one rotation blocking surface is assigned an inclined surface that is inclined with respect to the tangential direction, by means of which the cap can unidirectionally overcome the rotation blocking surface on the housing side without the application of radial force.
  • This incline thus allows the cap to be rotated relative to the housing in one direction without having to specifically deform it for this purpose. This facilitates the displacement of the above-mentioned cam in the area of the recess between the rotation blocking surfaces.
  • At least one locking lug can be provided on the cap as a cap-side fixing element, which interacts with a housing-side locking edge as a housing-side fixing element in the relative engagement position.
  • the locking lug on the cap side can be deflected radially outward in order to be disengaged from the locking edge and thus brought into the relative release position.
  • a locking lug is provided as a fixing element on the cap side, which interacts with a locking edge on the housing side and thereby initially prevents the cap from being pulled off.
  • the detent can be disengaged from the detent edge by deflecting it outward in this second sub-variant, it is preferred that the cap-side locking lug is deflected in an isolated manner without the entire cap cross-section being deformed.
  • a retaining lug can be provided as a fixing element on the cap.
  • the housing can have a bayonet ring with a slot extending in the circumferential direction, the slot being sufficiently large in an insertion area to allow the retaining lug on the cap to be inserted, and being provided in a retaining portion with a tapered section provided as a fixing element, so that the retaining lug cannot be axially withdrawn from the link when it is arranged in this retaining section.
  • the bayonet ring and the cap can be rotated relative to one another about the central axis.
  • the cap cooperates with the cap-side retaining lugs with a bayonet ring, whereby it is not the shape of the ring that matters, but rather the coulisse provided on it and extending in the circumferential direction, into which the retaining lugs can be axially inserted.
  • the retaining lugs can be pushed in in the push-in area of the coulisse, if necessary in a shape that is slightly bent towards the central axis.
  • 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-side web or the like which forms the tapered section.
  • the bayonet ring can also have a recess into which the retaining lug of the cap can engage radially when the retaining lug is located in the retaining section of the link, so that a relative rotation of the cap with respect to the bayonet ring is only possible after the opposite radial displacement of the retaining lug out of the recess
  • the additional recesses mentioned have the effect that the retaining lugs in the holding section of the backdrop are secured against relative rotation with respect to the backdrop.
  • these recesses can extend radially outward from the link. With such a design, the retaining lugs are pushed into the scenes in a slightly pretensioned state. When turning the bayonet ring against the Cap they get into the holding section and there jump again slightly radially outwards when these recesses are reached.
  • the retaining lugs of the cap In order to release such a connection, the retaining lugs of the cap must first be pressed radially inward in order to only then allow the cap to be rotated and then axially withdrawn relative to the bayonet ring or from the housing.
  • Fig. 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 to the discharge assembly 22 in the area of a coupling ring 28 and includes a liquid reservoir 32.
  • the discharge assembly 22 has at the distal end a discharge opening 24 at the end of an applicator tip 25 designed as a nasal olive and an approximately cylindrical and largely rotationally symmetrical jacket surface 23 between the nasal olive and the coupling ring 28 Dispenser 10 is gripped by the user, a recess 26 is provided in which an actuating lever 50 is arranged.
  • This actuating pusher 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 corresponds to 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 Fig. 1 to provide.
  • the inner components in the area of the discharge assembly 22 are exemplified by means of FIG Fig. 2 explained, but are identical for all exemplary embodiments.
  • the liquid storage 32 is via a Line 51 is connected to a pump 54.
  • This pump 54 has a movable cylinder 55 which can be pressed in together with the actuating lever 50.
  • the pump 54 has a valve arrangement 57, which is not described in more detail, which draws liquid through the line 51 when there is negative pressure in the pump cylinder 55 and which presses liquid in the direction of a second line 52 when there is overpressure in the pump cylinder 55, which in turn, with the interposition of an outlet valve 25a, leads to the discharge opening 24 leads.
  • the embodiment not encompassed by the invention Figures 2 to 5 To produce a child safety device, it has a rotary sleeve 60 which is attached on the outside of the jacket surface 23 of the housing 20.
  • a latching mechanism 61 ensures that this rotary sleeve 60 can only be rotated, but cannot easily be pulled off the housing 20.
  • the rotary sleeve 60 has an actuation recess 62 which is approximately the size of the outside of the actuation lever 50. In the locked position of the Fig. 2 and the Fig. 3 this actuation recess 62 is offset by 180 ° with respect to the actuation lever 50, so that the actuation lever 50 is covered by the rotary sleeve 60 and is not accessible.
  • Rotating the rotary sleeve 60 is not immediately possible, since the lateral surface 23 of the housing 20 is in particular from Fig. 2 is clearly provided with a bulge acting as a locking pawl 23a, which protrudes into the actuation recess 62. If the dispenser 10 is to be actuated from this state, it must first be in the direction indicated by arrow 3 in Fig. 4 illustrated way the pawl 23a are pressed radially inward. Only then can the rotary sleeve 60 be rotated through 180 °, so that the state of the Fig. 5 sets, in which the actuating recess 62 of the rotating sleeve 60 grants access to the actuating lever 50. Based on this state, the dispenser can now be used as intended. The actuating sleeve 60 is then rotated again through 180 °, so that the pawl 23a, which is kept under tension during actuation, jumps back into the actuating recess 62.
  • a rotatable rotary sleeve 60 is also provided, which is rotatable about the central axis 2 with respect to a lateral surface 23 and an actuating lever 50. This can also be brought into a rotary position in which the actuation recess 62 is not arranged above the actuation lever 50 and therefore prevents actuation.
  • recesses 33 are provided in the jacket surface 23 of the housing 20. Both the blocking webs 63 and the recesses 33 are laterally limited in the circumferential direction by rotation blocking surfaces 34, 64 Fig. 7 rotation of the rotating sleeve 60 is therefore not possible.
  • the rotary sleeve 60 is made here of a sufficiently deformable plastic, so that a force application in the direction of the arrows 5 is suitable in order to lift the blocking webs 62 offset by 90 ° from the respective depressions 33. The desired rotation of the rotary sleeve 60 with respect to the lateral surface 23 can then take place and thus the actuation recess 62 can be brought into a rotary position in which it allows the actuation lever 50 to be actuated.
  • the locking webs 63 and the depressions 33 are secured against rotation both in the position of the rotary sleeve in which it covers the actuation lever 50 and in that rotary position in which actuation through the actuation recess 62 is possible.
  • the dispenser 10 has a cap 80 which can be pushed on in the direction of the central axis 2 from the distal end and thus covers the discharge opening 24 as well as the actuating lever 50.
  • the child safety feature in this case is created by the cap, as in Fig. 10 can be seen, engages with translation blocking surfaces 82 behind corresponding translation blocking surfaces 36 on the housing 20 of the dispenser.
  • the cap 80 In order to release the connection created in this way, the cap 80 must be compressed in the direction of the arrows 5.
  • the available space 37b between the inside of the cap 80 and the latching web of the housing on which the translation blocking surfaces 36 are provided is not sufficiently large to bring the translation blocking surfaces 36, 82 out of engagement from one another.
  • the cap must be rotated 90 ° so that it reflects the state of the Figures 10 and 11 occupies. In this state, by applying force along the arrows 5, sufficient deformation can be achieved so that the cap can then be pulled off.
  • a cap 80 is again used.
  • This cap 80 has opposing projections 87, at the ends of which locking lugs 88 are provided.
  • a bayonet ring 40 is provided on the housing 20 of the dispenser. How out Fig. 13 As can be seen, this bayonet ring has a slot 42 on both sides, these slots each having an insertion area 42a and a holding area 42b. In the holding area 42b, the connecting links are tapered by a web 44 with respect to the insertion section 42a.
  • the cap 80 is put on by slightly pressing the extensions 87 towards one another so that the latching lugs 88 can dip into the insertion regions 42a.
  • the cap is then rotated relative to the bayonet ring 40, so that the state of the Figures 14 and 15 adjusts. In this state, the cap can no longer be pulled off directly, since the latching lugs 88 cannot exit through the tapered holding area 42b of the link 42. The cap 80 must therefore first be turned back relative to the bayonet ring 40.
  • FIG Fig. 16 A particular degree of security results when the holding area 42b according to FIG Fig. 16 is trained.
  • an outwardly directed recess 46 is also provided in the holding area, into which latching lugs 88 radially immerse.
  • a cap secured in this way can only be released when the extensions 87 are first pressed towards one another in the direction of the arrows 5, then the cap 80 is rotated relative to the bayonet ring 40 and only finally pulled off the housing 20.
  • the bayonet ring 40 can be designed to be non-rotatable with respect to the remaining housing sections, in particular the lateral surface 23.
  • the cap 80 instead of the cap 80 or in addition to the cap 80, it can also be designed to be rotatable about the central axis 2, so that it is particularly difficult for a child to keep the extensions 87 pressed while the bayonet ring 40 and the cap 80 are rotated against each other.
  • the child safety device is formed by the push button 50 itself.
  • the actuating pusher 50 has a tilting element 59 which is an integral part of the actuating pusher 50, but can be pivoted about a pivot axis 7 with respect to it.
  • a fixing element 58 is provided on this tilting element 59, which in the pressed-in state of the actuating lever 50 is behind a corresponding one
  • the fixing edge 27 of the housing snaps and thus secures the actuating lever when pressed.
  • a release can only be achieved by applying force in the direction of arrow 8 to a release surface 59a of the tilting element 59, which means that the actuating lever 50 automatically jumps into its radially outer end position, from where it is actuated again can be.
  • this design of a child safety device can be combined with other child safety features, as described in this application with regard to a rotating sleeve or a cap, via the design of the actuating lever 50. It is also possible to use several of the tilting elements 58 described on different sides of the actuating lever.
  • an opening 21 is provided on the side of the lateral surface 23 opposite the recess 26 for the actuating lever 50.
  • the actuating pusher is provided with at least one extension 53 which protrudes into this opening 21 and is pushed out here in the event that the actuating pusher is actuated.

  • this receiving sleeve 94 is designed to be sufficiently large so that the housing 20 can be completely received therein when it is pushed in through an open side 94a.
  • the case 20 is held non-positively in the receiving sleeve, this being made possible in the present case by a clamping ring 98 which rests on the outside of the reservoir 30.
  • the housing is pressed through lateral recesses 96 in the direction of the open end 94a and thus pulled out of it.
  • Such a sequence of movements, in which a sliding out of the housing 20 is provided, has proven to be difficult for children to implement.
  • the Figures 26 and 27 show a variant of the dispenser of FIG Figures 2 to 5 .

  • the cam 29 is inserted into this receiving area 48 as intended, in that the cap 80 is pushed on in a relative rotational position in which the cam 29 is not aligned with the coupling structure.
  • the cap 80 is then rotated with respect to the housing 20 so that it reaches the receiving area 48 via one of the bevels 38A.
  • the cap 80 is secured.
  • the rotation blocking surfaces 38B together with the cam-side rotation blocking surfaces counteract a rotational movement and thus prevent the cam 29 from leaving the receiving space 48 as a result of a rotational movement.
  • the holding element 39 prevents the cap 80 from being pulled off directly by means of its translation blocking surface 36.
  • the Figures 32 and 33 illustrate a possible variation.
  • the cap of the Fig. 32 corresponds to the cap described above with two ribs 38, each of which has a slope 38A.
  • the coupling structure on the cap 80 can therefore be introduced into the receiving space 48 in both directions of rotation.
  • the right rib 38 is designed differently. It has no bevel and is preferably also higher than the left rib 38 in the radial direction. Thus, the insertion and possibly also the removal of the cam 29 from the receiving space 48 is only possible in one direction of rotation.
  • the housing 20 has two cams 29 and the cap 80 accordingly has two coupling structures which are each provided opposite one another.
  • other numbers can 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 donor according to the Figures 34 and 35 as well as 36A and 36B is a dispenser not covered by the invention with a child safety device which is not implemented via a cap, but could also be in addition.
  • the child safety device is similar to the design of the Figures 17 and 18 is brought about by a lockability of the actuating lever 50.
  • a second recess 66 is provided in the housing 20 in addition to the recess 26 for the actuating lever 50, through which a blocking element 68 that can be displaced orthogonally to the actuating lever can be subjected to force by means of a force application surface 68A.
  • This blocking element 68 has a distal end 68B, corresponding to which a recess 50A is provided in a side wall of the actuating lever 50. The blocking element 68 can engage in this.
  • Figures 36A and 36B show the released and locked state of the blocking element 68.
  • the blocking element is displaced upwards in relation to the figures, with it being displaced slightly radially against the force of a spring element 69 in the area of a housing edge by means of a bevel 68C.
  • this spring element has the effect that the hook-like distal end 68B is snapped into this recess 50A in such a way that a child-proof state is then achieved. In this state, the actuating pusher 50 cannot be pressed in and therefore no liquid can be discharged.
  • the blocking element In order to return to the released state from this state, the blocking element must be pressed in against the force of the spring element 69, so that the aforementioned snap-in connection is released. Only then can the blocking element 68 be withdrawn so that it releases the actuating lever 50.
  • the distal end 68B can have a hook-like shape which, unlike the above, is oriented to the right, so that a movement of the blocking element into the released position is only possible as soon as the actuating lever has been depressed a little.
  • the relative mobility of the blocking element 68 with respect to the housing can also be configured differently.
  • a rotatable or swiveling blocking element is suitable to make it more difficult for small children to release.
