Definitions

  • the invention relates to a discharge head for discharging liquids, in particular pharmaceutical liquids or personal care products as well as disinfectants and cleaning agents, and a liquid dispenser with such a discharge head.
  • a discharge head serves to discharge liquid from a liquid reservoir.
  • it has a discharge channel and a discharge opening at the end of the discharge channel.
  • the discharge head is preferably depressed relative to the liquid reservoir.
  • such a discharge head can be manually switched between a secured and a released state, with the discharge of liquid being prevented in the secured state and with the discharge being in the released state made possible by liquid.
  • a generic discharge head has an outer shell with a discharge opening through which the liquid discharged through the discharge opening can be discharged when the discharge opening and the discharge opening are in an aligned arrangement and no diaphragm preventing the discharge is provided between them.
  • a generic discharge head has one of two possible configurations: According to a first configuration, it has an inner body on which the discharge opening is provided and which can be rotated about a switching axis relative to the outer shell, the discharge opening being in an open rotary position is arranged flush with the discharge opening of the outer shell and is covered by the outer shell in a closed rotational position. With such a design, it is therefore provided that the prevention or enabling of the discharge depends on the relative rotational position of the discharge opening and the discharge opening.
  • a generic discharge head in a second configuration, has a screen body which is arranged within the outer shell and can be rotated about a switching axis relative to the outer shell, the screen body having a blocking section which, in a closed rotational position, is arranged between the discharge opening and the discharge opening in the outer shell and releases the discharge opening in an open rotary position.
  • Discharge heads of the type described or similar are from the documents EP 2707311 B1 and US8777061B1 famous.
  • the object of the invention is to increase security against unintentional discharge in a generic dispenser or discharge head and in particular to ensure a child safety function.
  • a discharge head which, in accordance with the generic discharge head described at the outset, has on the one hand an outer shell with a discharge opening and on the other hand an inner body or screen body which is arranged on the inside of the outer shell and can be rotated about a switching axis relative to the outer shell. It does not matter whether the outer shell or the diaphragm body or inner body remains non-rotatably relative to a liquid reservoir to which the discharge head is coupled during rotation.
  • the discharge opening which is preferably in the form of a discharge nozzle with a spray opening and/or a turbulence device, is preferably provided in a rotationally fixed manner with respect to the outer shell in the case of a design with a diaphragm body, and is preferably provided on this inner body in a design with an inner body and is therefore rotatable in relation to the outer shell.
  • a releasable snap-on coupling is provided, by means of which the outer shell on the one hand and the inner body or the visor body on the other hand can be rotationally coupled in the closed rotary position, so that the open rotary position can only be reached again after manual application of force to a release surface of the releasable snap-on coupling.
  • a snap coupling is understood to mean a coupling device which, when the inner body or cover body rotates relative to the outer shell, when a closed rotary position is reached, suddenly assumes a coupled state by mechanically relieving a previously prestressed latching section, which cannot be restored again solely by the application of an opposing torque is resolvable. If the discharge head in these has been brought to the closed state, it requires the preferably radial and / or axial application of force to the release surface in order to elastically deflect said locking section again, so that a reverse rotation in the direction of the open rotary position can then be achieved.
  • the snap coupling is preferably designed in such a way that an audible noise is generated when the closed rotary position is reached and/or when the open rotary position is reached, so that the user can acoustically and possibly also haptically detect when the respective end position has been reached.
  • the discharge is made possible and prevented by the relative rotatability of the inner body and thus the discharge opening in relation to the outer shell.
  • the inner body has an outer peripheral shell section and a line section which is integrally connected thereto and protrudes into an inner region of the shell section and through which the discharge channel passes.
  • the shell section is preferably the carrier of the elements of the snap coupling provided on the inner body. Furthermore, a gripping surface is preferably provided on the shell section for the purpose of manually rotating the inner body relative to the outer shell.
  • the line section protrudes into an interior area and, together with the discharge channel, encompasses the supply line to the discharge opening.
  • the discharge opening can be provided in one piece on the inner body or can be formed by a separate component in a manner that will be explained below.
  • the shell section is preferably designed only to be rotatable relative to the outer shell, while the line section is also designed to be depressible.
  • a deformable connection area is preferably provided, which acts as a kind of joint and is provided between the shell section and the line section.
  • the connection area is preferably formed by at least one thin-walled plastic bridge, which is elastically deformed when pressed down.
  • the line section is preferably designed to be coupled directly to a valve tube of a pressure accumulator and for this purpose has a liquid inlet aligned with the switching axis.
  • the valve tube is preferably inserted into this. An axial displacement of the liquid inlet leads to the valve tube being pressed in and thus to the valve opening.
  • the line section can be directly accessible from the outside, so that it can be pressed down by direct application of force to an upper side of the line section.
  • a configuration is advantageous in which the outer shell has the depressible actuating handle, in particular in the form of an actuating surface which is arranged on the upper side and can be pressed in downwards. This acts indirectly on the line section. The line section is thus subjected to a downward force by the operating handle of the outer shell.
  • a screen body is provided which, depending on its rotational position relative to the outer shell, is arranged between the discharge opening and the discharge opening and can prevent liquid discharge there.
  • the shutter body is preferably provided with an outer peripheral shell portion which, unlike the first configuration, is not rotatable in unison with the discharge port.
  • the discharge opening in this configuration is preferably provided in a rotationally fixed manner with respect to the outer shell and a discharge opening provided therein.
  • a line section is particularly preferably provided in one piece on the component forming the outer shell. Similar to the above-mentioned line section in the first configuration, this line section is penetrated by the discharge channel which supplies the discharge opening with liquid.
  • the discharge opening can be defined in one piece in the line section or can be formed by a separate component.
  • a depressible operating handle is preferably provided on the outer shell.
  • the line section is preferably connected in one piece to the actuating handle.
  • This line section preferably also has a liquid inlet which is aligned with the switching axis and acts on a valve tube of the liquid reservoir in the manner described above.
  • the snap coupling provided according to the invention is designed to couple the inner body in the case of the first configuration or the visor body in the case of the second configuration on the one hand and the outer shell on the other hand in the closed rotary position in such a way that a mere application of torque in the direction of the open rotary position is not sufficient to move the closed rotary position to leave.
  • an additional force must be applied to the release surface.
  • the coupling in the closed position is achieved in particular in a form-fitting manner, preferably by latching in a primarily radial direction in relation to the shifting axis. In principle, however, partial or complete axial locking is also possible.
  • the latching takes place in that a section which is elastically deflected from its basic position during the movement into the closed rotary position snaps into a recess of a holding profile or a holding opening, forming the said form fit.
  • the elastically deflected section can be provided on the outer shell and/or on the inner body or visor body.
  • the snap-on coupling is formed by a latching extension that protrudes outwards from the inner body or the visor body and can be elastically deflected radially inward, as well as a corresponding holding opening or holding profile on the outer shell.
  • the release surface is preferably formed by an end face of said latching extension, so that a separate release surface can be dispensed with.
  • the latching extension is therefore immediately acted upon manually in order to disengage it from the holding recess or holding opening so that the open rotary position can then be reached again.
  • constructions are also possible in which the release surface is separated from the latching extension and indirectly applies a force to it.
  • a particularly advantageous design provides that the holding opening or holding recess, into which the latching extension jumps when it reaches the closed rotary position, is formed by the discharge opening itself.
  • the user In order to reach the open rotary position starting from the closed rotary position, the user first presses on the latching extension arranged in the discharge opening, so that it is pushed inwards out of the discharge opening. Then the rotary movement into the open rotary position is possible.
  • the holding opening or holding profile can also be provided separately from the discharge opening, in particular on the side of the outer shell facing away from the discharge opening.
  • the latching extension is preferably provided on a radially deflectable surface section which is provided via a tangentially aligned deformation area on an adjacent section of the inner body or the visor body.
  • the latching extension In order for the latching extension to snap into the corresponding holding opening or holding profile when the closed rotary position is reached, it must first be elastically prestressed. One possibility for this is that the latching extension is always elastically prestressed when it is not snapped into the closed rotational position. However, this comes with the risk that the elasticity degrades over time due to relaxation. It is therefore preferred that the latching extension is also at least partially relaxed in the open rotary position and is tensioned during a rotary movement in the direction of the closed rotary position before the closed rotary position is reached.
  • an insertion bevel is preferably provided on an inside of the outer shell or on an outside of the inner body or the visor body and/or on the latching extension, by means of which the latching extension is elastically deflected, in particular radially inwards or outwards, when the inner body or the visor body is moved relative to the outer shell in the direction of the closed rotary position.
  • the outer shell is secured on the inner body or on the visor body not only in the closed rotary position, but also in the open position.
  • the security in the closed rotary position cannot be overcome solely by a rotary movement
  • the security in the open rotary position can preferably be overcome solely by a rotary movement against an increased resistance moment.
  • the visor body or the inner body and the outer shell preferably have cooperating holding means which bring about the securing in the open rotary position.
  • Said latching extension which is also part of the snap-on coupling, is preferably also part of these holding means. In particular, it preferably jumps into a recess when the open rotary position is reached and generates an audible noise, which the user interprets as confirmation that the open rotary position has been reached.
  • the described securing in the open rotary position reduces the risk of erroneous discharge, which could occur if the outer shell and the inner body/visor body are unintentionally in a position a few degrees away from the open rotary position.
  • the discharge opening is formed by a discharge opening component, such as in particular a nozzle component, the discharge opening component having a different color than the inner body or the diaphragm body.
  • the discharge opening component can be designed in green and the inner body or the diaphragm body can be designed in red.
  • the discharge opening component can be seen through the discharge opening and signals the readiness for discharge with the green color.
  • the closed rotary position only the inner body or the screen body can be seen through the discharge opening, which signalizes with its red color that the discharge head is currently blocked.
  • a discharge head in the closed rotary position the discharge is prevented at least by the fact that liquid discharged through the discharge opening cannot escape through the discharge opening, either because the discharge opening and the discharge opening are not aligned (first configuration) or because there is a gap between the two Aperture is arranged (second configuration).
  • twisting into the closed rotary position also prevents the discharge in an additional way.
  • the inner body or the visor body is matched to the outer shell in such a way that in the closed rotary position, pressing down an actuating handle of the outer shell is blocked.
  • This can be done in particular by arranging the line section in the closed rotary position above a blocking section, which acts as a stop and thereby prevents the line section from being pressed down.
  • the outer shell has a free area on the side facing away from the discharge opening for lateral accessibility of an actuating handle and the inner body or the cover body also has a free area for lateral accessibility of the Operating handle has.
  • the free areas are arranged in an overlapping manner, so that the actuating handle can be accessed from the side and pressing it down with a finger arranged laterally on the discharge head is easy.
  • the closed rotational position on the other hand, the free areas are offset from one another, so that lateral accessibility is impeded. Even if viewed in isolation this does not reliably prevent actuation, it makes it clear to the user that the discharge in the closed rotary position is not intended.
  • the inner body or the cover body is rotated about the switching axis relative to the outer shell.
  • the outer shell is non-rotatably attached to a liquid reservoir in a positive or non-positive manner, so that this liquid reservoir is held and on the other hand, the inner body or the panel body can be rotated in relation thereto.
  • the manual application of force to the inner body or the visor body preferably takes place in the direction of rotation by means of a gripping surface provided thereon, which is designed to be easy to grip, in particular by structuring the surface.
  • a gripping surface provided thereon, which is designed to be easy to grip, in particular by structuring the surface.
  • the gripping surface for rotating the inner body or the visor body is preferably provided separately from the latching extension and/or the release surface and is preferably provided opposite the release surface.
  • the opposed arrangement makes it particularly difficult for children to simultaneously apply force to the release surface and the gripping surface for the purpose of transition to the pivoted open position.
  • the invention also relates to a liquid dispenser with such a discharge head.
  • this liquid dispenser has a liquid reservoir to which the discharge head is attached.
  • Such a dispenser can be designed in particular for dispensing pharmaceutical liquids or personal care products as well as disinfectants and cleaning agents and, when ready for use, has a liquid reservoir filled with such a liquid.
  • the liquid reservoir is preferably designed as a pressure reservoir, ie it is already under pressure, for example due to compressed air or a propellant, before it is put into operation.
  • the liquid reservoir preferably has an outlet valve which can be actuated by means of the inner body or a line section attached to the outer shell.
  • the outlet valve preferably has a depressible valve tube, which opens the outlet valve when depressed. This valve tube is preferably inserted into the above-described liquid inlet of the line section and can be depressed by it.
  • the discharge head described makes it more difficult to unintentionally discharge liquid due to its secured closed rotary position, especially if a dispenser with such a discharge head gets into the hands of children.
  • a child safety device is only sufficiently secure if it is difficult to remove the discharge head as a whole from the liquid reservoir.
  • the discharge head and in particular its outer shell is connected to the liquid reservoir in such a way that a separating force of 100 Newtons is not sufficient to remove the discharge head from the liquid reservoir.
  • it can be a snap connection that ensures this.
  • it can also be expedient to design the connection in such a way that it cannot be detached without being destroyed. In such a case, a separation of the discharge head and liquid reservoir is only possible with the risk of destruction, in particular by the holding sections of the discharge head being bent or broken. This is usually only possible with a force that cannot be applied, at least by small children.
  • FIG. 1 shows a liquid dispenser 100 according to the invention in an overall view.
  • the liquid dispenser 100 has a liquid reservoir 102, which in the present case is in the form of a pressure reservoir, in which a pharmaceutical liquid or a personal care product is stored under pressure.
  • the liquid reservoir 102 is closed by a crimp cover. It has an outlet valve 104 with a valve tube 106. By depressing this valve tube 106, based on 1 downwards, the outlet valve 104 can be opened so that liquid flows through the valve tube 106 into a discharge head 10 which is fastened to the crimped cover by means of a snap-in connection.
  • the discharge head 10 has a liquid inlet 16 which is pushed onto the valve tube 106 .
  • a discharge channel 12 extends to a discharge opening 14, which is preferably designed as a spray opening and can be provided with an upstream turbulence chamber in order to cause the turbulence of the exiting fluid and thus the generation of a spray jet.
  • a line section 44 of the discharge head 10 can be depressed from top to bottom by manual application of force. This also depresses the liquid inlet, which thereby presses the valve tube 106 downwards and thereby opens the outlet valve 104 .
  • the discharge head 10 has an outer shell component 20 and an inner body 40 inserted therein.
  • a discharge opening component 90 is provided, which is inserted into a corresponding recess of the inner body 40.
  • the outer shell component 20 is provided for latching attachment to the liquid reservoir 102 .
  • an actuating handle 30 is formed in one piece, which is attached to the jacket section 23 only by means of a narrow bridge and is thus elastically depressible relative to the jacket section 23.
  • the already mentioned inner body 40 is inserted into the outer shell component 20 .
  • This inner body 40 has an outer peripheral shell section 42 and a line section 44 integrally connected thereto.
  • the already described components of the liquid inlet 16, the discharge channel 12 and the receptacle for the discharge opening component 90 are provided in this line section 44.
  • Line section 44 is formed in one piece on a partial section which can be pressed down by elastic deformation in relation to the surrounding sections of shell section 42, so that a force acting on actuating handle 30 is passed on to line section 44 and line section 44 in turn presses valve tube 106 to open the valve Valve can depress.

  • This release surface 62 is provided with an insertion bevel 64 on one side.
  • the shell section 42 has a gripping surface 48 approximately opposite the latching extension 66, the use of which will be explained below.
  • the inner body 40 is inserted into the outer shell component 20 from below and is rotatable about a switching axis 2 therein.
  • the outer shell component 20 and the inner body 40 can be moved relative to one another purely in rotation about the switching axis 2 . They have corresponding guide surfaces for this.

  • the inner body 40 and the outer shell component 20 are in one position relative to one another closed turning position.
  • the latching extension 66 is arranged within the discharge opening 22, which thereby forms a holding opening 68 of the snap coupling 60.
  • the discharge opening 14 is not arranged in alignment with the discharge opening 22 in this position, so that for this reason alone discharge is not possible.
  • discharge in this position is made more difficult by the fact that the actuation handle 30 is prevented from being pressed down by a blocking section 41 of the inner body 40 .
  • a cut-out free area 46 in the inner body 40 in the closed state Figures 2 and 3 offset by 90° with respect to a corresponding free area 26 of the outer shell component 20, so that it is obvious to the user that actuation should not take place in this rotational position.
  • the inner body 40 In order to place the discharge head in an open state in which discharge is then possible by actuating the actuating handle 30 , the inner body 40 must be rotated counterclockwise by about 90° with respect to the outer shell component 20 . However, this is only possible if the latching extension 66 has been disengaged from the discharge opening 22 by direct manual application of force to its release surface 62 . this is in 3 indicated with an arrow. It is therefore intended that with reference to 2 the user presses the latching extension 66 radially inwards and in this state makes the relative rotation which is shown in figure 5 is indicated with an arrow. For the purpose of relative rotation, the previously described gripping surface 48 is provided, which is displaced counterclockwise by the user.
  • the detent extension 66 is thereby removed from the discharge opening 22, while the discharge opening 14 is brought into alignment with the discharge opening 22.
  • the Figures 4 and 5 show the opening state achieved in this way. In this state, liquid discharge by depressing the operating handle 30 is then possible.
  • the pressing down also indirectly causes the line section 44 of the inner body 40 to be pressed down and thus the valve tube 106 to be pressed down.

  • Locking projection 66 is manually pressed inwards from the discharge opening 22, as indicated by the arrow in FIG Figure 7B clarified. While the latching extension 66 is still being pushed inwards manually, the user begins the rotary movement by applying force to the gripping surface 48 as shown in FIG Figure 7C clarified. When the open rotary position is reached, the latching extension 66 snaps into an inside recess of the outer shell component 20 . This makes a noise and signals the user that the rotation has been sufficiently far. In addition, the engagement of the latching extension 66 in the depression 28 also leads to a safeguard against leaving the open state too easily.
  • the discharge head 10 according to Figures 8 to 12 also has an outer shell component 20 and an inner body 40 . Deviating from the prescribed design, however, no latching extension is provided which protrudes into the discharge opening 22 in the closed state. Instead, a section on which the gripping surface 48 is provided simultaneously forms the latching extension 66 and its end face 62. In order to form a snap coupling 60 with this, a holding profile 70 is provided in the free area 26 of the outer shell component 20. In the secured closed state of the Figures 8 and 9 the latching extension 66 is positioned so far radially on the outside that a rotary movement in the direction of an open rotary position is prevented by a pinnacle 72 of the holding profile 70 .
  • the secured state is secured in almost the same way as in the first embodiment, as far as preventing an unintentional opening, for example in luggage, is concerned.
  • child safety is the embodiment of the Figures 2 to 7D more suitable because of the required simultaneous application of force there mutually opposite elements of the latching extension 66 and the gripping surface 48 achieving the opening rotary position is difficult for children.
  • a suitable design of the holding profile 70 and the locking extension 66 in the embodiment of Figures 8 to 12 However, operation by children is made at least significantly more difficult, particularly when pressing in the gripping surface in order to release the snap connection requires an operating force in excess of 20 N.
  • the Figures 13 to 16 shows an alternative construction.
  • an outer shell component 20 is also provided here, which has a discharge opening 22 through which liquid which has previously been discharged through the discharge opening 14 located behind it can be discharged.
