Definitions

  • a squeeze bottle dispenser according to the invention is a liquid dispenser, for example for dispensing pharmaceutical liquids, which has a dimensionally stable liquid reservoir, the walls of which are at least partially elastically depressible, so that the liquid in the liquid reservoir can be pressurized.
  • Generic squeeze bottle dispensers are widely used. In particular, they are used for pharmaceutical liquids such as eye drop liquid.
  • a squeeze bottle dispenser of the type described is, for example, from the document DE 10 2016 210 992 B3 known.
  • Childproof squeeze bottle dispensers are known from post-published European patent application 21155900.0.
  • the object of the invention is primarily to provide a squeeze bottle dispenser that offers a high degree of security against unintentional operation and/or against operation by playing children.
  • a squeeze bottle dispenser which has a liquid reservoir designed as a squeeze bottle and a discharge head with a discharge opening.
  • the discharge head is manufactured as a separate assembly and coupled to the liquid reservoir, for example by a snap-in connection or a threaded connection.
  • designs are also possible in which the discharge head and the liquid reservoir or at least their outer surfaces are formed by a one-piece component.
  • the liquid dispenser is preferably filled with a pharmaceutical liquid, for example a liquid containing imidazoline to relieve conjunctival irritation.
  • a pharmaceutical liquid for example a liquid containing imidazoline to relieve conjunctival irritation.
  • the liquid reservoir preferably has an internal volume of less than 50 ml, in particular less than 20 ml.
  • the liquid reservoir is designed as a squeeze bottle.
  • the squeeze bottle body is preferably designed with an inherent rigidity that allows the internal volume to be reduced by at least 5% with a pressure of 20 Newtons on both sides.
  • the wall of the liquid reservoir is preferably made from a soft plastic, in particular from polyethylene terephthalate (PET), from polyethylene (PE) or from a cycloolefin copolymer (COC).
  • the dispenser according to the invention can be designed to deliver a jet of liquid or a spray.
  • the squeeze bottle dispenser is preferably designed as a drip dispenser.
  • the squeeze bottle dispenser preferably has drop-forming means in the area of the discharge opening, in particular in the form of a drop-forming surface surrounding the discharge opening, where discharged liquid collects until the amount of liquid is sufficient for a drop to form, which detaches from the drop-forming means and falls down.
  • a squeeze bottle dispenser has a protective sleeve which is captively connected to the liquid reservoir.
  • a main axis of the dispenser which is formed by the dispensing direction of the dispenser and/or the central axis of the liquid reservoir, this can be repeatedly displaced axially relative to the liquid reservoir between a protective position and a release position.
  • the relocatability can be purely translational.
  • the protective sleeve it is also possible for the protective sleeve to be displaceable in translation and rotation, for example superimposed in the manner of a threaded movement or sequentially in the manner of a bayonet movement.
  • a captive attachment of the protective sleeve to the squeeze bottle dispenser is understood in the context of the invention to mean that the protective sleeve does not separate from the squeeze bottle dispenser during normal use. The fact that a separation is possible with brute force does not conflict with captiveness within the meaning of the invention.
  • the protective sleeve In the protective position, the protective sleeve is arranged relative to the liquid reservoir in such a way that it either completely prevents the liquid reservoir from being compressed or at least makes it very difficult by covering access to the outer wall of the liquid reservoir. This prevents liquid from being discharged.
  • the protective sleeve In the release position, on the other hand, the protective sleeve enables the liquid reservoir to be compressed and thus the liquid to be discharged.
  • the protective sleeve is shifted in relation to the liquid reservoir to such an extent that it no longer represents any obstacle or at least allows a simplified application of force to the liquid reservoir compared to the protective position.
  • the protective sleeve can also be displaced at least in translation relative to the liquid reservoir.
  • the degree of displaceability in the axial direction in relation to the main axis is preferably at least 20 mm, particularly preferably at least 30 mm. This dimension describes the axial path that the protective sleeve can move between opposite end positions, ie between the end position assigned to the release position and the end position assigned to the protective position.
  • the protective sleeve is sufficiently rigid to prevent significant reduction in the internal volume of the fluid reservoir when force is applied to the protective sleeve.
  • the protective sleeve is preferably made of a rigid plastic, in particular polycyclohexylenedimethylene terephthalate/glycol-modified (PCTG), polypropylene (PP), a cycloolefin copolymer (COC), a cycloolefin polymer (COP), polyethylene terephthalate (PET) or made of high-density polyethylene (HDPE).
  • PCTG polycyclohexylenedimethylene terephthalate/glycol-modified
  • PP polypropylene
  • COC cycloolefin copolymer
  • COP cycloolefin polymer
  • PET polyethylene terephthalate
  • HDPE high-density polyethylene
  • the squeeze bottle dispenser has at least one guide surface along which the protective sleeve can be displaced in a guided manner.
  • the outside of the liquid reservoir directly as a guide surface.
  • a configuration is preferred in which a component that is separate from the liquid reservoir provides the guide surface.
  • a possible design provides that at least one guide surface is provided on an outside of a guide ring.
  • This guide ring is attached to the liquid reservoir, to the discharge head or in an intermediate area in between.
  • An inside of the guide ring is designed in such a way that the ring cannot be displaced or can hardly be displaced relative to the liquid reservoir in the axial direction.
  • the guide ring On the outside, the guide ring has a sliding surface along which the protective sleeve can be slidably displaced.
  • a design in which the guide ring is attached to a tapered neck area of the liquid dispenser is particularly advantageous.
  • its inner diameter is smaller than the diameter of the liquid reservoir and of the discharge head on both sides of the tapered neck area.
  • Such a ring can be assembled by placing the guide ring in the neck area before the discharge head is attached to the liquid reservoir.
  • the guide ring is designed in such a way that it can also be assembled when the discharge head is already attached to the bottleneck.
  • This can be achieved, for example, by a guide ring interrupted by a separating slot, which is temporarily widened for assembly in the axial direction or from the side.
  • the guide ring can be designed as an interrupted guide ring which has an interruption in a segment which spans a maximum of 120° and which preferably spans a maximum of 10°.
  • Such an interruption of the ring structure or at least a slotted design is advantageous in order to be able to expand the guide ring during automated assembly.
  • a guide ring provided with an interruption or slot and the protective sleeve held by it are matched to one another in such a way that the guide sleeve prevents the guide ring from widening, which would be sufficient to pull the guide ring over the liquid reservoir or the discharge head and thus separate the protective sleeve from the squeeze bottle dispenser .
  • An alternative design of a guide ring provides that the guide ring is designed as a multi-part guide ring, in particular as a two-part guide ring.
  • the guide ring is only assembled from the several guide ring segments in the area of the neck area of the liquid reservoir.
  • an insertion bevel is preferably provided on the protective sleeve and/or on the guide ring.
  • the protective sleeve is preferably pushed on from a side facing away from the discharge opening.
  • the insertion bevel is provided at the upper edge of the protective sleeve or at the lower end of the guide ring.
  • the outside of the guide ring can have at least one guide structure extending in the direction of movement of the protective sleeve, for example in the form of a short vertical groove.
  • This allows a protective sleeve provided with a corresponding inwardly pointing guide structure to be guided not only in a longitudinally movable manner by means of the guide ring, but at the same time to be secured in a rotationally fixed manner with respect to the guide ring. It has been shown that a higher guiding stability and a reduced tilting tendency can be achieved in this way.
  • the guide ring preferably also forms a stop that limits the displacement of the protective sleeve in at least one direction of movement.
  • the guide ring can also form a latching edge of an anti-displacement device, which will be explained below.
  • An alternative design of the guide surface provides that at least one guide surface is provided on an inside of a guide sleeve surrounding the protective sleeve.
  • This guide sleeve can be held on the liquid reservoir or on the discharge head or between the liquid reservoir and discharge head, in particular using an intermediate ring located in between.
  • the guide sleeve surrounds the liquid reservoir and is stationary relative to it in the axial direction or can only be moved axially relative to it to a small extent.
  • the guide sleeve has at least one recess through which the liquid reservoir can be compressed. Two mutually opposite recesses are preferably provided.
  • the recesses preferably have an extension in the axial direction of at least 10 mm, preferably at least 15 mm.
  • the protective sleeve can be arranged between the guide sleeve, which is largely stationary axially with respect to the liquid reservoir, and the outer wall of the liquid reservoir. If the protective sleeve is in its protective position, it is located in the area of the at least one recess, so that it is impossible for the liquid reservoir to be subjected to force. If the protective sleeve is in its release position, it releases the recess at least in part and thus enables the squeeze bottle store to be compressed.
  • the guide sleeve is preferably attached to the squeeze bottle dispenser by means of an intermediate ring.
  • the intermediate ring can also be designed as a slotted ring or as a ring with an interruption in order to to facilitate assembly.
  • a guide ring composed of several ring segments in the manner described is also possible.
  • the intermediate ring is preferably designed for axial fixation on the guide sleeve.
  • the intermediate ring and the guide sleeve are preferably latched to one another in a form-fitting manner, with a groove being provided on one of the parts and a web engaging therein on the other part.
  • the protective sleeve can be guided by the guide ring or the guide sleeve in that the outside of the guide ring and the inside of the protective sleeve or the outside of the protective sleeve and the inside of the guide sleeve have a substantially matching cylindrical shape.
  • interlocking guide structures are provided on the guide surface and opposite thereto on the protective sleeve, through which the protective sleeve is guided in a rotationally fixed manner relative to the guide surface or through which the protective sleeve is guided in terms of rotation and translation relative to the guide surface, for example in the manner of a Threaded movement or a bayonet movement.
  • a recessed guide groove can be provided on one side, into which a guide web or a guide cam on the opposite side engages.
  • Such a structure leads to more reliable guidance, in which tilting is easily avoidable.
  • the guide groove has a helix shape at least in sections, the mentioned thread movement is achieved. This makes it possible to displace the protective sleeve between the release position and the protective position by applying torque and thereby indirectly causing axial displacement.
  • the guide groove can have a partial section on one or both axially spaced ends, which extends circumferentially to the main axis, so that it does not run in the axial direction of the main axis.
  • the protective sleeve and the liquid reservoir can be held in the protective position or the release position by means of these end sections.
  • a displacement safety device can be provided, by means of which the protective sleeve can be secured against displacement in its protective position. To transfer to the release position, the displacement lock must first be unlocked with a separate handling.
  • the displacement safeguard can have at least one elastically deflectable latching element, which is stationary either with respect to the liquid reservoir and the guide sleeve or with respect to the securing sleeve and which, in the protective position, interacts with a latching edge provided on the respective other side in such a way that a translational or a rotational movement and thus indirectly a translational movement of the protective sleeve relative to the liquid reservoir is prevented.
  • the user In order to bring the liquid dispenser into the release position, the user must first deflect the latching element by applying direct manual force so that it can be guided past the latching edge.
  • the elastically deflectable locking element can be attached in particular to the protective sleeve or to the guide sleeve, in particular as a one-piece molded section which is connected to surrounding wall parts of the sleeve via an elastically deformable material bridge. It is particularly preferred if the deflectable latching element is provided on the protective sleeve itself. If it is a protective sleeve that can be displaced within a guide sleeve, the corresponding latching edge is preferably provided on the guide sleeve, in particular as the edge of an opening through which the latching element can be pressed. This opening can be identical to the recess through which the force is applied to the squeeze bottle in the release state. If the protective sleeve is mounted on a guide surface provided on the inside of a guide ring, the latching edge is preferably provided on this guide ring.
  • the elastically deflectable latching element in particular in the case of a design with a guide ring, it can be useful to design the elastically deflectable latching element as a rocker element with two cantilevers located opposite one another on both sides of a tilting axis. One of the cantilevers can then be used for latching with the latching edge, while the other cantilever is actuated manually to unlock it.
  • the rocker element thus causes a reversal of direction for the purpose of arming.
  • the protective sleeve In the protective position, the protective sleeve surrounds the liquid reservoir at least in those areas in which it would be accessible from the outside. In the release position, the protective sleeve is opposite shifted to the liquid storage translationally. Designs are conceivable in which the translational displacement of the protective sleeve takes place in the direction of the discharge opening or away from the discharge opening.
  • the protective sleeve is closer to the discharge opening in the release position than in the protective position. This makes it possible to use an upper edge of the protective sleeve as a contact surface that is placed in the area of the skin area where liquid is to be applied. In the case of eye drops, for example, the contact surface can be placed in the area of the eyebrow in order to enable a particularly reliable and reproducible discharge.
  • the contact surface of the protective sleeve is arranged in the release position such that it is positioned a maximum of 15 mm away from the discharge opening in relation to the main axis and particularly preferably protrudes beyond the discharge opening.
  • Holding means are preferably provided, in particular in the form of stops on the guide ring and on the protective sleeve, in order to prevent the protective sleeve from being pulled off the guide ring.
  • Another design, in which the protective sleeve is displaced away from the discharge opening in the release position, is preferably realized by means of the guide sleeve described. This is able to securely hold the protective sleeve that has been shifted away from the discharge opening.
  • the elongation of the dispenser as a whole caused by the relocation of the protective sleeve can offer a considerable advantage in handling.
  • holding means are preferably provided, which prevent the protective sleeve from being pulled off in the opposite direction to the discharge opening.
  • these can be stops on the protective sleeve and the guide sleeve.
  • a particularly advantageous design provides that the stop on the side of the guide sleeve is formed by an edge delimiting the actuation recess.
  • the protective sleeve In the case of a design with a guide sleeve, in order to be able to shift the protective sleeve arranged inside the guide sleeve into the release position, the user must be able to grasp the protective sleeve. This can be done through the exits. However, in order to make handling easier, it can also be provided that the protective sleeve has a distal end section which, even when the protective sleeve is in the protective position, extends over the lower end the guide sleeve protrudes. The additional length of the protective sleeve can be used when the protective sleeve is designed with a closed bottom, in order to arrange electronic dispenser components, such as a counter, within the receiving space defined in this way.
  • the protective sleeve covers the liquid reservoir at least in phases.
  • the protective sleeve can be made of a transparent plastic. Printing on the outside of the liquid reservoir or on a label attached to the outside can thus be read through the protective sleeve. If a guide sleeve is provided, this can also be made of transparent plastic.
  • the squeeze bottle dispenser preferably has a protective cap which protects the discharge opening when it is in place and which is removed to use the dispenser and then put back on again.
  • a protective cap can in particular be a protective cap with at least one ventilation opening, this ventilation opening preferably still being closed when delivered.
  • the protective cap can provide additional security in that it interacts with the protective sleeve in such a way that when the protective cap is on or at least when the protective cap has not yet been opened for the first time, the protective sleeve is prevented from moving, in particular by the protective cap being arranged where the protective sleeve is to be moved into the Release position must be relocated.
  • the liquid dispenser has an outer sleeve which at least temporarily surrounds the bottle body.
  • This can in particular be the protective sleeve described above or the guide sleeve described above.
  • a ring element is provided for fastening or guiding the outer sleeve on the bottle body, on the outside of which the outer sleeve is fastened in a fixed or displaceable manner.
  • the ring element is preferably designed as a slotted or interrupted ring element which has an interruption in a segment which spans a maximum of 120° and which preferably spans a maximum of 10°. This enables assembly of the ring element by temporary widening. If the ring element is in position, the outer sleeve can be pushed on.
  • the ring element is then secured against expansion by the outer sleeve in such a way that it cannot be pulled over the bottle body or over the discharge head and is thus separated from the liquid reservoir. If the ring element is pulled over the outer sleeve to the discharge head or to the bottom of the liquid reservoir, the ring element reaches an area of the discharge head or the liquid reservoir with a larger diameter and is thus expanded until it hits the inside of the outer sleeve and a further displacement with it is prevented.
  • a liquid dispenser according to this separate aspect of the invention can also fulfill individual or all of the features mentioned above in addition to the squeeze bottle dispenser.

  • the squeeze bottle dispenser 10 has a discharge head 12 with an outer housing 14, which is pierced by a discharge opening 16 at the distal end.
  • the squeeze bottle dispenser 10 also has a liquid reservoir 20 which is designed as a squeeze bottle and the walls of which can therefore be pressed in order to reduce the internal volume of the liquid reservoir 20 and to increase the pressure accordingly.
  • the discharge head is attached to the open end of the liquid reservoir 20 .
  • the pressure in the course of the compression of the liquid reservoir 20 pushes the liquid contained downwards in the direction of the discharge head when the discharge opening is oriented and, after the pressure-related opening of a discharge valve 18, reaches the discharge opening 16.
  • the squeeze bottle dispenser 10 can be, for example, a drop dispenser, in particular for ophthalmic use, whose discharge opening is designed for dispensing drops, in particular by a drop formation surface surrounding the discharge opening 16 on the outside, in particular with a surrounding sharp-edged tear-off edge.
  • the dispenser 10 can include a protective cap 22 to protect this discharge opening 16 .
  • the protective cap is provided with ventilation openings to allow the drop formation surface to dry quickly after use.

  • the child safety device includes a protective sleeve 30 which is inserted into a guide sleeve 50 .
  • the guide sleeve 50 is provided in the region of its lateral surface on opposite sides with a recess 54 through which the application of force to the liquid reservoir 20 takes place as intended. However, this application of force is prevented when the protective sleeve 30 is fully inserted into the guide sleeve 50 and thus in the through Figures 3 and 4 way shown the recesses 54 blocked.
  • the guide sleeve 50 is provided on its inside with guide surfaces 52 opposite one another in the form of two guide grooves 53 extending in the direction of the main axis 2 .

  • the protective sleeve 30 has stop webs 37 projecting outwards on both sides at the upper edge, which prevent the protective sleeve 30 from being completely pulled out of the guide sleeve 30 from the guide sleeve 50 . As soon as the stop 37 hits the lower edge of the window recesses 54, which forms a further stop, it is no longer possible to pull out the protective sleeve 30 any further.
  • the guide sleeve 50 has a snap-in opening 59 whose lower end edge forms a snap-in edge 64 .
  • an inwardly elastically deflectable latching element 62 is provided, which is a one-piece part of the protective sleeve 30 in the manner of a tongue cut free in a U-shape.

  • the intermediate ring 70 is in the in figure 5 Apparent way not designed closed all the way around, but provided with an interruption 74. This interruption 74 allows the intermediate ring to be slid onto a tapered region 20B of the liquid reservoir 20 from above or below, but in particular also from the side. It can then be pressed together far enough for the combination of guide sleeve 50 and protective sleeve 30 to be pushed on from below.
  • Figure 6A shows the child safety device mounted in this way in a sectional representation. It can be seen that a groove 78 is used on the outside of the intermediate ring 70 in order to fasten an inward-facing retaining web 58 of the guide sleeve 50 here.
  • Figure 6A shows the protective position of the protective sleeve 30.
  • the protective sleeve 30 blocks its recesses 54 in this position, so that it is not possible for the user to compress the liquid reservoir 20.
  • the user In order to prepare the dispenser for operation, the user first has to elastically press in the latching element 62 . Once this is done, the user can pull the protective sleeve down by applying force to the protective sleeve 30 in relation to the guide sleeve 50 or the discharge head 12, so that the state of the Figure 6B adjusts The shift down is limited by the stops 37,57. In the position of Figure 6B the dispenser is now significantly lengthened as a whole, so that more comfortable handling and safer placement of the dispenser, for example above an eye to be treated, can be achieved. If the liquid reservoir is now subjected to a force on both sides through the recesses 54 , the pressure in the liquid reservoir increases, so that the discharge valve 18 opens and liquid is discharged through the discharge opening 16 .
  • a bevel on the latching element 62 causes this to be indirectly elastically deflected inwards until it springs back into the opening 59 and restores the protective state.
  • Figures 7A and 7B differs from that of Figures 3 to 6B in that the protective sleeve is extended at its lower end, so that it can also be used in the protective position Figure 7A protrudes downwards beyond the guide sleeve 50. This can be the transfer to the release position Figure 7B facilitate.
  • Figures 8 and 9 are that of the previous ones Figures 3 to 7B quite similar.
  • An essential difference is that no purely translational movement of the protective sleeve 30 is provided here, but a superimposed translational and rotational movement.
  • a predominantly helical guide groove 35 is provided on an outer side of the protective sleeve 30, which transitions into horizontal sections only at its ends.
  • a guide cam 55 which is provided on the inside of the guide sleeve 50 , is arranged within the groove.
  • the helical guide groove 35 ensures that the transfer from the protective position 8 into the release position 9 first the locking element 62 has to be pressed in the manner already described, but then the protective sleeve 30 is not pulled out directly, but is unscrewed, as it were, by a rotary movement and a translational movement indirectly caused thereby.
  • Figures 10 to 13B has fundamental differences from the previous exemplary embodiments. How out 12 As can be seen, only two additional components are provided here to achieve an actuation safeguard, namely a guide ring 40 which, similar to the intermediate ring 70, is pushed onto a tapered area 20B of the liquid reservoir 20 from above or below, but in particular from the side, and a protective sleeve 30, which is pushed onto the liquid reservoir 20 surrounding the guide ring 40.
  • Introductory bevels 38 are provided at the upper edge of the guide sleeve 30 and ensure that the guide ring 40 is temporarily compressed during assembly of the protective sleeve 30 in order to be able to expand again below the guide bevels 38 .
  • the guide ring 40 fulfills a plurality of functions. From the protective position of 13A it is not possible to pull off the protective sleeve 30 downwards, since the bevels previously used during assembly only act in the opposite direction. Furthermore, it is also initially not possible to shift the protective sleeve 30 upwards, since a latching element 62 designed as a rocker element rests with an upper edge on the latching edge 64 of the guide ring 40 . Only when the lower half of the latching element 62 is pressed is the upper half tilted outwards so that the protective sleeve can then be pushed upwards. The end position is in the in Figure 13B Apparent position is reached in which a stop 64 of the guide ring 40 comes to rest against an inwardly pointing stop 31 of the protective sleeve 30 .
  • Figure 13B shows the release position in which a force can now be applied to the liquid reservoir 20. Deviating from Figure 13B This application of force occurs when the dispenser is in an angled position with the discharge opening 16 pointing downwards.
  • the upper end edge of the protective sleeve 30 can be used in this release position in that the contact surface 34 there is placed against a part of the user's skin in order to allow drops to be dispensed as precisely as possible.
  • the contact surface 34 can be placed against the user's eyebrow, for example.
  • FIG. 14 shows an alternative design of a guide ring 40. This is not provided with an interruption 44 that allows expansion, but is instead formed from two ring segments 40A, 40B, which can be connected to one another via interacting coupling means 41. This allows the guide ring of 14 to attach after the liquid reservoir 20 and the discharge head 12 have already been connected to one another by feeding the two ring segments in the tapered area 20B from opposite sides and locking them around the bottle neck.
  • the guide ring 40 of 14 also has a guide structure 48 on the outside. These are short vertical grooves. These grooves can interact with corresponding webs on the inside of the protective sleeve 30, so that the protective sleeve 30 cannot be rotated about the main axis 2 relative to the guide ring. As a result, safe guidance and a low tendency to tilting can be achieved.
