Abstract

The invention relates to a dispenser (11) for discharging, especially spraying media, especially liquid medicaments. The inventive dispenser discharges a desired quantity of the medicament in just one or optionally, a few strokes. The user can operate the dispenser with three fingers, the thumb pressing an activating depressor (80) in the direction of activation and discharge. The aim of the invention is to prevent the dispenser from being activated unintentionally and to protect the discharge opening (44) against dirt and contamination. To this end, a protective cap (90) which covers the entire discharge section (13) and the holding surfaces (14) for operating the dispenser is provided. Said protective cap also has rod-shaped projections (93) which extend as far as the activating depressor (80) and fix said depressor in place so that the dispenser cannot be activated whilst the protective cap is on. Removing the protective cap, which is fixed in place with a snap connection, unblocks the activating mechanism.

Description

ANWENDUNGSGEBIET UND STAND DER TECHNIKAPPLICATION AREA AND PRIOR ART

Die Erfindung betrifft einen Spender nach dem Oberbegriff des Anspruchs 1.The invention relates to a dispenser according to the preamble of Claim 1.

Ein solcher Spender ist aus-der EP 218 840 A2 (entsprechend US 4 921 142 A) bekannt geworden. Er besitzt ein Gehäuse, eine daran vorgesehene Griffläche zur Auflage wenigstens eines Fingers und einen Ausbringabschnitt mit einer Ausbringöffnung, z.B. einer Zerstäubungsdüse sowie mit einem Betätigungsdrücker zur Betätigung der Ausbringeinrichtung. Er weist ferner eine abnehmbare Schutzkappe auf, die die Ausbringöffnung abdeckt. Diese Schutzkappen sind vorgesehen, um eine Verschmutzung der Ausbringöffnung zu verhindern, da mit derartigen Spendern meist pharmazeutische Produkte ausgegeben werden.Such a dispenser is from EP 218 840 A2 (corresponding US 4 921 142 A) become known. It has a housing a gripping surface provided thereon for support at least a finger and a discharge section with a discharge opening, e.g. an atomizing nozzle and with an actuation button to actuate the spreading device. He points also a removable protective cap on the discharge opening covers. These protective caps are intended to be used To prevent contamination of the discharge opening, as with such dispensers mostly issued pharmaceutical products become.

Der Spender wird mit dem Daumen betätigt, der auf den Betätigungsdrücker drückt. Dieser ist weitgehend vom Gehäuse abdeckt und nur durch einen Ausschnitt, der etwa dem Daumenprofil entspricht, zugänglich, um zu verhindern, daß er unbeabsichtigt betätigt wird.The dispenser is operated with the thumb on the actuation button suppressed. This is largely from the housing covers and only through a cutout that roughly corresponds to the thumb profile corresponds, accessible to prevent him is operated unintentionally.

Derartige Spender enthalten oft Medikamente, die von dem Patienten zur sofortigen Anwendung bereit gehalten werden. So werden z.B. Medikamente auf die Nasenschleimhaut appliziert, weil sie von dort aus am schnellsten und am verträglichsten in den Blutkreislauf gelangen. Insbesondere Medikamente zur Bekämpfung von Migräne und anderen Kopfschmerzen werden so verabreicht.Such donors often contain medication from that Patients are kept ready for immediate use. So e.g. Medication applied to the nasal mucosa, because it is the fastest and most compatible from there get into the bloodstream. In particular drugs for Combating migraines and other headaches are like this administered.

Dies bedingt, daß der Patient die Spender mit sich führen muß. Dabei besteht stets die Gefahr, daß trotz des Schutzmantels um den Betätigungsdrücker eine versehentliche Betätigung erfolgt, beispielsweise durch Gegenstände in einer Handtasche.This requires the patient to carry the donor with them got to. There is always the risk that despite the protective jacket accidental actuation around the actuation button done, for example by items in a handbag.

Aus der FR 2 570 000 A ist ein Adapter bekannt geworden, der auf einem Behälter mit einem Aerosolventil angebracht wird und dieses betätigt. Er weist eine Schutzkappe auf, die mittels Sollbruchstellen mit einen Gehäusemantel verbunden sind. Innere Rippen ragen durch den Adapter hindurch und stützen sich am Behälter ab, so daß erst nach Abbrechen der Sollbruchstellen und Abnehmen der Schutzkappe eine Betätigung möglich ist.An adapter has become known from FR 2 570 000 A is placed on a container with an aerosol valve and operated this. It has a protective cap that connected to a housing jacket by means of predetermined breaking points are. Inner ribs protrude through the adapter and are supported on the container, so that only after the Predetermined breaking points and removal of the protective cap an actuation is possible.

Aus der nicht vorveröffentlichen WO 98/00354 ist eine Zerstäuberpumpe mit einem die Ausbringöffnung enthaltenden Adapter bekannt geworden, der von einer Schutzkappe überdeckt ist, die sich auf einem Band der Schraub- oder Bördelkappe abstützt, mit der die Pumpe auf einem Behälter befestigt wird. Die Schutzkappe ist gegen versehentliches Abnehmen gesichert. From the not pre-published WO 98/00354 is an atomizer pump with one containing the discharge opening Adapter known, which is covered by a protective cap is that on a tape of the screw or crimp cap with which the pump is attached to a container becomes. The protective cap is against accidental removal secured.

AUFGABE UND LÖSUNGTASK AND SOLUTION

Aufgabe der Erfindung ist es, einen Spender der eingangs erwähnten Art im Hinblick auf die Sicherheit gegen versehentliche Betätigung weiter zu verbessern.The object of the invention is a dispenser of the beginning kind mentioned with regard to security against accidental Further improve activity.

Diese Aufgabe wird dadurch gelöst, daß die Schutzkappe Blockiermittel zum Blockieren des Betätigungsdrückers aufweist.This object is achieved in that the protective cap Has blocking means for blocking the actuating button.

Die Schutzkappe bekommt dadurch eine Doppelfunktion. Sie deckt einerseits die Ausbringöffnung ab und ermöglicht, den Spender ohne Gefahr der Verschmutzung oder Kontaminierung der Ausbringöffnung auch in sonst verschmutzungsgefährdeter Umgebung aufzubewahren und andererseits sorgt sie durch die Blockierung des Betätigungsdrückers dafür, daß, solange sie auf den Spender aufgesetzt ist, eine versehentliche Betätigung unterbleibt.This gives the protective cap a double function. she covers the discharge opening on the one hand and enables the Donor without risk of contamination or contamination the discharge opening even in otherwise polluted areas To preserve the environment and on the other hand it takes care of the Blocking the push button for that as long as it is placed on the dispenser, an accidental actuation omitted.

Zur Betätigung des Spenders wird ohnehin die Schutzkappe abgenommen und gibt den Betätigungsdrücker zum Betätigen frei.The protective cap is used to operate the dispenser anyway removed and gives the actuation button to actuate free.

Besonders bevorzugt ist eine Ausführung, bei der die Schutzkappe auch die Griffläche betätigungsverhindernd abdeckt. In diesem Falle wird eine versehentliche Betätigung vor Abnahme der Schutzkappe auch dadurch verhindert, daß der Benutzer keine Angriffsfläche für die Betätigung findet. Er kann zwar den Daumen auf den Betätigungsdrücker legen, findet jedoch keinen Widerhalt, der normalerweise durch Zeige- und Mittelfinger an der Griffläche gefunden wird. Somit wird ihm signalisiert, daß er zuerst die Schutzkappe abnehmen muß, bevor er die Betätigung vornimmt. Selbst wenn er einen Widerhalt an der Schutzkappe finden würde, so würde dies nicht zu einer versehentlichen Betätigung führen. Die Krafteinleitung würde innerhalb der Schutzkappe bleiben, d.h. die auf den Betätigungsdrücker ausgeübte Kraft würde auf das Gehäuse und die Ausbringeinrichtung nicht übertragen werden.An embodiment in which the protective cap is particularly preferred also covers the grip surface to prevent actuation. In in this case, an accidental activation before acceptance the protective cap also prevents the user there is no target for actuation. He can put your thumb on the push button, but finds no resistance, usually through the index and middle fingers is found on the grip surface. So it will signals that he must first remove the protective cap, before doing the operation. Even if he has one Would find resistance to the protective cap, so this would do not lead to accidental activation. The introduction of force would stay inside the protective cap, i.e. the force exerted on the actuating button would act on the Housing and the delivery device are not transferred.

Es sei bemerkt, daß eine Originalitätssicherung für derartige Spender bereits in der WO 96/24439 beschrieben wurde. Dies geschieht durch Sollbruch-Materialbrücken zwischen dem Gehäuse und der bei Betätigung bewegbaren Funktionseinheit, die aus Betätigungsdrücker und Pumpenzylinder sowie ggf. einer den Pumpenzylinder aufnehmenden Hülse besteht. Diese Originalitätssicherung, die gleichzeitig einen den vollständigen Austrag sicherstellenden Druckpunkt (Mindestkraft) erzeugt, ist bei der vorliegenden Erfindung ebenfalls zusätzlich anwendbar. Da die Sollbruchkraft so eingestellt sein muß, daß der Spender zum Gebrauch betätigbar ist, kann sie die versehentliche Benutzung nicht verhindern, sondern nur signalisieren. Daher ist eine Kombination dieser Druckpunkt/Originalitätssicherungs-Merkmale mit der Betätigungssicherung durch die Schutzkappe sinnvoll und vorteilhaft.It should be noted that tamper evidence for such Donors have already been described in WO 96/24439. This happens through predetermined breaking material bridges between the Housing and the functional unit movable when actuated, which consist of actuation pushers and pump cylinders as well as there is a sleeve receiving the pump cylinder. This Tamper-evident, which at the same time ensures complete Discharge ensuring pressure point (minimum force) generated, is also additional in the present invention applicable. Because the breaking strength should be set like this must that the dispenser can be operated for use, it can do not prevent accidental use, only signal. Therefore, a combination of these pressure point / tamper-evident features with the actuation protection sensible and advantageous through the protective cap.

Besonders vorteilhaft anwendbar ist die Erfindung bei Einmal-Zerstäubern oder solchen, die eine Charge in wenigen aufeinanderfolgenden Hüben oder Hubabschnitten ausbringen. Wenn jedoch nach einer Betätigungsphase die Schutzkappe wieder aufgesetzt werden kann, dann ist sie auch für andere Spender sinnvoll, die für zahlreiche Hübe ausgelegt sind. Der Spender dient zur Angabe von strömungsfähigen Medien, insbesondere von flüssigem Pharmazeutika in zerstäubter oder in Tropfen dosierter Form.The invention is particularly advantageously applicable to single-use atomizers or those that a batch in a few consecutive Apply strokes or stroke sections. If however, the protective cap again after an actuation phase can be put on, then it is also for other donors sensible, which are designed for numerous strokes. The donor is used to indicate flowable media, in particular of liquid pharmaceuticals in atomized or in drops dosed form.

Diese und weitere Merkmale gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei einer Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können. Die Unterteilung der Anmeldung in einzelne Abschnitte sowie Zwischen-Überschriften beschränken die unter diesen gemachten Aussagen nicht in ihrer Allgemeingültigkeit.These and other features go beyond the claims also from the description and the drawings, wherein the individual features individually or separately several in the form of sub-combinations in one embodiment of the invention and in other fields be and advantageous as well as protective designs can represent. The division of the application into individual sections as well Inter-headings limit those made under them Statements are not generally applicable.

Die wie die meisten Teile des Spenders aus Kunststoff bestehende Schutzkappe ist in ihrer Grundfläche der Ovalform der Grifflächen 14 angepaßt und bildet von dort aus einen haubenförmig sich nach oben verjüngenden, geschlossenen Raum. Die Unterkante 91 dieser Schutzkappenhaube übergreift eine Randausnehmung 92 am Gehäuse, so daß die Schutzkappe in aufgesetztem Zustand eine kontinuierliche Fortsetzung des Gehäusemantels 15 bildet. Es entsteht somit ein Körper, der in der Form etwa einem Taschenfeuerzeug ähnelt und sich dementsprechend gut transportieren und handhaben läßt.A protective cap 90 can be put over the dispenser 11, the entire spreading section 13 and the gripping surfaces 14 covered. Like most parts of the plastic dispenser existing protective cap is in the base of the Adjusted oval shape of the grip surfaces 14 and forms from there a hood-like, closed, tapering towards the top Room. The lower edge 91 of this protective cap overlaps an edge recess 92 on the housing so that the protective cap in attached state a continuous continuation of the Housing shell 15 forms. This creates a body that similar in shape to a pocket lighter and similar can be transported and handled accordingly.

An der Innenseite der Schutzkappe sind zwei seitliche Vorsprünge 93 angeformt, die stegartig von der Mitte der Flachseiten nach unten ragen, und zwar durch Ausschnitte 94. Sie greifen in je eine Ausnehmung 95 an der Oberkante des Mantels 81 des Betätigungsdrückers ein und legen sich dort durch eine lösbare Schnappverbindung 96 fest. Sie sichern die Schutzkappe gegen zu leichtes Abziehen nach oben. Gleichzeitig stützen sich aber ihre Enden 97 in der Ausnehmung 95 ab und bilden somit Blockiermittel 98, die bei aufgesetzter Schutzkappe eine Bewegung des Betätigungsdrückers 80 nach oben, d.h. in Betätigungsrichtung, verhindern.There are two side projections on the inside of the protective cap 93 molded, the web-like from the middle of the flat sides protrude downwards through cutouts 94. You engage in a recess 95 on the upper edge of the jacket 81 of the actuation button and lay there through a releasable snap connection 96 firmly. You secure the protective cap against pulling up too easily. simultaneously but their ends 97 are supported in the recess 95 and thus form blocking means 98 when the protective cap is in place a movement of the actuation button 80 upwards, i.e. in the direction of actuation.

FUNKTION VON FIG. 1 BIS 3FUNCTION OF FIG. 1 TO 3

Der mit einem Pharmazeutikum als Medium 50 gefüllte Spender wird mit aufgesetzter Schutzkappe 90 geliefert. In dieser Form ist eine Betätigung nicht möglich, weil der Betätigungsdrücker 80 durch die Blockiermittel 98 an einer Bewegung gehindert ist. Im Falle eines Druckes auf den Betätigungsdrücker 80 stützt sich dieser über seine Ausnehmung 95 an den Enden 97 der Vorsprünge 93 ab, die die Kraft auf die Schutzkappe übertragen. Durch die Tatsache, daß die Schutzkappe den gesamten oberen Abschnitt des Spenders, d.h. nicht nur den Ausbringabschnitt 13, sondern auch die Grifflächen 14 überdeckt, kann sich keine Gegenkraft aufbauen, die zwischen dem Gehäuse und dem Betätigungsdrücker wirkt und somit eine Betätigung auslösen könnte. Es findet ein völliger Kraftschluß zwischen Betätigungsdrücker und Schutzkappe statt und das Gehäuse bleibt betätigungskräftefrei.The dispenser filled with a pharmaceutical medium 50 is supplied with the protective cap 90 attached. In this Form an actuation is not possible because of the actuation button 80 by the blocking means 98 in motion is hindered. In case of pressure on the actuation button 80 this is based on its recess 95 to the Ends 97 of the protrusions 93, which exert the force on the protective cap transfer. Due to the fact that the protective cap entire top portion of the dispenser, i.e. not just that Spreading section 13, but also covers the gripping surfaces 14, no counterforce can build up between the Housing and the push button acts and thus a Could trigger actuation. There is a complete adhesion between push button and protective cap instead and the housing remains free of actuation forces.

Wenn jetzt die Schutzkappe 90 nach Überwindung der Haltekraft der Schnappverbindung 96 durch Abziehen nach oben vom Gehäuse abgezogen wird, ist der Spender betriebsbereit. Nun kann der Benutzer Zeigefinger und Mittelfinger auf die Grifflächen 14 legen und mit dem Daumen auf die Betätigungsfläche 17 des Drückers 18 drücken. Vor Beginn der Bewegung der Funktionseinheit Hülse 18/Ampulle 19/Kolben 26 nach oben ist ein Druckpunkt zu überwinden, dessen Größe durch die Sollbruchkraft der Materialbrücken 22 bestimmt wird. Somit ist sichergestellt, daß das Ausbringen bereits mit einem ausreichenden Druck beginnt und in einem Zuge durchgeführt wird. Über die Stege 83 wird dann die Hülse 18 und über die Stege 20 die Ampulle 19 nach oben bewegt. Die Nadel 37 durchsticht den Steg 29 des Verschlußstopfens 26 und stellt die Verbindung zur Ausbringöffnung 44 her. Danach trifft die untere Stirnfläche 52 des Kolbenschaftes 34 auf die Oberseite des Verschlußstopfens und drückt diesen als Pumpenkolben in die Ampulle 19 hinein, so daß die Ausbringeinrichtung als nicht reversierbare Schubkolbenpumpe arbeitet und das Medium mit durch die Druckpunktfunktion vorgegebener Kraft durch die Ausbringöffnung 44 versprüht.If now the protective cap 90 after overcoming the holding force the snap connection 96 by pulling upwards from the housing is withdrawn, the dispenser is ready for use. Now he can User index finger and middle finger on the grip surfaces 14 place and with your thumb on the operating surface 17 of the Press pusher 18. Before the movement of the functional unit begins Sleeve 18 / ampoule 19 / piston 26 up is a To overcome pressure point, its size by the predetermined breaking force the material bridges 22 is determined. This ensures that the spreading already with a sufficient Printing begins and is carried out in one go. About the The webs 83 then become the sleeve 18 and the webs 20 Ampoule 19 moved upwards. The needle 37 pierces the Web 29 of the plug 26 and makes the connection to the discharge opening 44. Then the lower face hits 52 of the piston shaft 34 on the top of the sealing plug and presses it into the pump piston Ampoule 19 into it, so that the dispensing device is not reversible thrust piston pump works and the medium with force given by the pressure point function by the Spray opening 44 sprayed.

Es ist zu erkennen, daß die Schutzkappe 90 den Spender zu einem leicht handhabbaren und betätigbaren Gerät macht, das ohne Gefahr einer Verschmutzung oder ungewollten Betätigung vom Patienten zu transportieren ist und durch Abziehen der Schutzkappe sofort betätigungsbereit ist. Durch die das Gehäuse ergänzende und gestalterisch fortführende Form der Schutzkappe wird nicht nur eine ästhetische, sondern auch eine dem Benutzer die Funktion einleuchtend darbietende Gestaltung erzeugt.It can be seen that the protective cap 90 is towards the dispenser an easy to use and operate device that without risk of contamination or unintended operation is to be transported by the patient and by pulling the Protective cap is ready for operation immediately. Through that Complementary and creative form of the housing Protective cap is not only an aesthetic, but also a function that makes sense to the user Design creates.

AUSFÃœHRUNGSBEISPIEL NACH FIG. 4EMBODIMENT ACCORDING TO FIG. 4

Der in Fig. 4 perspektivisch dargestellte Spender 11 entspricht in allen Einzelheiten und auch in der Funktion dem nach den Figuren 1 bis 3. Hier sind lediglich die die Blockiermittel 98 bildenden stegartigen Vorsprünge 93 von der Mitte der Flachseiten an die runden Schmalseiten der Schutzkappe verlegt. Die Vorsprünge 93 haben an ihren Enden 97 keine Schnappverbindung, sondern sind als durchgehende T-förmige Stege ausgebildet, die in Ausschnitte 94 im Gehäuse eingreifen. Eine Abzugsicherung der Schutzkappe 90 vom Gehäuse 12 geschieht über Rastnasen 99 an der Mitte der flachen Innenseiten der Schutzkappe 90. Die Rastnasen 99 greifen in entsprechende Ausnehmungen 100 im Bereich der umlaufenden Randausnehmung 92 des Gehäuses ein und legen die Schutzkappe widerhakenartig fest. Sie ist somit gegen Abziehen vom Gehäuse gesichert, was die Blockierung des Betätigungsdrückers noch verbessert.The dispenser 11 shown in perspective in FIG. 4 corresponds in all details and also in the function of the according to Figures 1 to 3. Here are only those Blocking means 98 forming web-like projections 93 from the Center of the flat sides on the round narrow sides of the protective cap laid. The protrusions 93 have 97 at their ends no snap connection, but are as a continuous T-shaped Webs formed in cutouts 94 in the housing intervention. A trigger protection of the protective cap 90 from Housing 12 is done via locking lugs 99 at the center of the flat inner sides of the protective cap 90. The locking lugs 99 engage in corresponding recesses 100 in the area of circumferential edge recess 92 of the housing and insert the Protective cap like a barb. It is therefore against pulling off secured by the housing, which is blocking the actuation button still improved.

Um die Schutzkappe abnehmen zu können, drückt der Benutzer auf die durch entsprechende Riffelung diese Betätigung anzeigende Druckflächen 101. Damit drückt er die Schutzkappe etwas zusammen, so daß sich die widerhakenartigen Rastnasen 99 durch entsprechende Weitung des Ovalprofils der Schutzkappe aus den Ausnehmungen 100 lösen und die Schutzkappe abgezogen werden kann.To remove the protective cap, the user presses on the corresponding corrugation this actuation indicating pressure areas 101. He presses the protective cap something together so that the barb-like latches 99 by widening the oval profile of the protective cap accordingly loosen from the recesses 100 and the protective cap can be deducted.
