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.

MANUELL BETÄTIGBARER SPENDER UND SCHUTZKAPPE MIT BLOCKIERMITTELN ZUM BLOCKIEREN DER BETÄTIGUNGMANUALLY ACTUABLE DISPENSER AND PROTECTIVE CAP WITH BLOCKING AGENTS FOR BLOCKING THE ACTUATION
ANWENDUNGSGEBIET UND STAND DER TECHNIKAPPLICATION AREA AND PRIOR ART
Die Erfindung betrifft einen Spender mit einer manuell betätigbaren Ausbringeinrichtung, insbesondere zum ggf. zerstäubten Ausbringen einer Charge in einem oder wenigen Hüben.The invention relates to a dispenser with a manually operable dispensing device, in particular for dispensing a batch in one or a few strokes.
Ein solcher Spender ist aus der EP 218 840 (entsprechend US 4 921 142) bekannt geworden. Er besitzt ein Gehäuse, eine daran vorgesehene Griffläche zur Auflage wenigstens eines Fingers und einen Ausbringabschnitt mit einer Ausbringöff- nung, 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 has become known from EP 218 840 (corresponding to US 4 921 142). It has a housing, a gripping surface provided thereon for supporting at least one finger and a dispensing section with a dispensing opening, e.g. an atomizing nozzle and with an actuating button for actuating the dispensing device. It also has a removable protective cap that covers the discharge opening. These protective caps are provided to prevent contamination of the dispensing opening, since dispensers of this type mostly dispense pharmaceutical products.
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, which presses on the actuation button. This is largely from the housing covers and only accessible through a cutout, which corresponds approximately to the thumb profile, to prevent it from being 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 dispensers often contain medications that are ready for immediate use by the patient. For example, Medications applied to the nasal mucosa, because from there they get into the bloodstream the fastest and most tolerably. Medications to combat migraines and other headaches are administered in this way.
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 means that the patient must carry the donor with them. There is always the risk that, in spite of the protective jacket around the actuation button, an accidental actuation takes place, for example due to objects in a handbag.
AUFGABE UND LÖSUNGTASK AND SOLUTION
Aufgabe der Erfindung ist es, einen derartigen Spender im Hinblick auf die Sicherheit gegen versehentliche Betätigung weiter zu verbessern.The object of the invention is to further improve such a dispenser with regard to security against accidental activation.
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. It covers the dispensing opening on the one hand and enables the dispenser to be stored in an environment otherwise prone to contamination without risk of contamination or contamination of the dispensing opening, and on the other hand it ensures that as long as it remains by blocking the actuation button is placed on the dispenser, no accidental activation takes place.
Zur Betätigung des Spenders wird ohnehin die Schutzkappe abgenommen und gibt den Betätigungsdrücker zum Betätigen frei.To operate the dispenser, the protective cap is removed anyway and releases the actuation button for actuation.
Besonders bevorzugt ist eine Ausführung, bei der die Schutzkappe auch die Grifflache 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 Mittel- finger an der Grifflache 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 Kraft- einleitung 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 is particularly preferred in which the protective cap also covers the grip surface to prevent actuation. In this case, accidental actuation before the protective cap is removed is also prevented in that the user does not find any contact surface for the actuation. Although he can put his thumb on the actuation button, he does not find any resistance that is normally found by the index and middle fingers on the surface of the handle. This signals to him that he must first remove the protective cap before operating. Even if he found resistance on the protective cap, it would not lead to an accidental actuation. The force application would remain within the protective cap, i.e. the force exerted on the actuation button would not be transmitted to the housing and the delivery device.
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 Druck- punkt/Originalitätssicherungs-Merkmale mit der Betätigungssicherung durch die Schutzkappe sinnvoll und vorteilhaft.It should be noted that tamper evidence for such dispensers has already been described in WO 96/24439. This is done by means of predetermined breaking material bridges between the housing and the functional unit which can be moved upon actuation and which consists of actuation pushers and pump cylinders and, if appropriate, a sleeve which receives the pump cylinder. This tamper-evident device, which at the same time generates a pressure point (minimum force) ensuring complete discharge, can also be used in the present invention. Since the predetermined breaking force must be set so that the dispenser can be actuated for use, it cannot prevent accidental use, but can only signal it. Therefore, a combination of these pressure point / tamper-evident features with the actuation protection through the protective cap make sense and are advantageous.
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 disposable atomizers or those which deliver a batch in a few successive strokes or stroke sections. However, if the protective cap can be put back on after an actuation phase, then it also makes sense for other dispensers that are designed for numerous strokes. The dispenser is used to indicate flowable media, in particular liquid pharmaceuticals in atomized or dosed form.

Über den Spender 11 kann eine Schutzkappe 90 gestülpt werden, die den gesamten Ausbringabschnitt 13 und die Grifflächen 14 überdeckt. 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, which covers the entire dispensing section 13 and the gripping surfaces 14. The protective cap, like most parts of the dispenser made of plastic, is adapted in its base to the oval shape of the grip surfaces 14 and from there forms a hood-shaped, tapered, upwardly closed space. The lower edge 91 of this protective cap overlaps an edge recess 92 on the housing, so that the protective cap in the fitted state is a continuous continuation of the Housing shell 15 forms. The result is a body that resembles a pocket lighter in shape and can therefore be easily transported and handled.
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.On the inside of the protective cap, two lateral projections 93 are formed, which protrude downward like a web from the middle of the flat sides, through cutouts 94. They each engage in a recess 95 on the upper edge of the casing 81 of the actuation button and lie through there a releasable snap connection 96 firmly. They secure the protective cap against being easily pulled off upwards. At the same time, however, their ends 97 are supported in the recess 95 and thus form blocking means 98 which, when the protective cap is attached, cause the actuating pushbutton 80 to move 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 dieserThe dispenser filled with a pharmaceutical as medium 50 is supplied with a protective cap 90 attached. In this
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.Form, an actuation is not possible because the actuation button 80 is prevented from moving by the blocking means 98. In the event of pressure on the actuating pushbutton 80, it is supported via its recess 95 at the ends 97 of the projections 93, which transmit the force to the protective cap. The fact that the protective cap covers the entire upper portion of the dispenser, i.e. not only the spreading section 13, but also covering the grip surfaces 14, no counterforce can build up which acts between the housing and the actuation push button and could thus trigger an actuation. There is a complete frictional connection between the actuation button and protective cap 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 Funktions- einheit Hülse 18/Ampulle 19/Kolben 26 nach oben ist einIf now the protective cap 90 after overcoming the holding force of the snap connection 96 by pulling upwards from the housing is withdrawn, the dispenser is ready for use. Now the user can place his index finger and middle finger on the grip surfaces 14 and press the actuation surface 17 of the pusher 18 with his thumb. Before the movement of the functional unit sleeve 18 / ampoule 19 / piston 26 upwards is a
Druckpunkt zu überwinden, dessen Größe durch die Sollbruchkraft der Materialbrücken 33 bestimmt wird. Somit ist sichergestellt, daß das Ausbringen bereits mit einem ausreichenden Druck beginnt und in einem Zuge durchgeführt wird. Über die Stege 43 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 Ver- schlußstopfens und drückt diesen als Pumpenkolben in dieTo overcome pressure point, the size of which is determined by the predetermined breaking force of the material bridges 33. This ensures that the application starts with sufficient pressure and is carried out in one go. Then the sleeve 18 is moved over the webs 43 and the ampoule 19 is moved upward over the webs 20. The needle 37 pierces the web 29 of the sealing plug 26 and establishes the connection to the discharge opening 44. The lower end face 52 of the piston shaft 34 then hits the top of the sealing plug and presses it into the piston as a pump piston
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.Ampoule 19, so that the dispensing device works as a non-reversible thrust piston pump and sprays the medium through the dispensing opening 44 with a force predetermined by the pressure point function.
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 dasIt can be seen that the protective cap 90 makes the dispenser into an easily manageable and actuatable device which can be transported by the patient without risk of contamination or unintentional actuation and is immediately ready for operation by pulling off the protective cap. Through that
Gehäuse ergänzende und gestalterisch fortführende Form der Schutzkappe wird nicht nur eine ästhetische, sondern auch eine dem Benutzer die Funktion einleuchtend darbietende Gestaltung erzeugt.The form of the protective cap, which complements the housing and continues the design, produces not only an aesthetic but also a design that provides the user with an obvious function.
AUSFUHRUNGSBEISPIEL NACH FIG. 4EXAMPLE OF EXAMPLE OF 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 dieThe dispenser 11 shown in perspective in FIG. 4 corresponds in all details and also in function to that according to FIGS. 1 to 3. Here are only those
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.Blocking means 98 forming web-like projections 93 from the Installed in the middle of the flat sides on the round narrow sides of the protective cap. The projections 93 have no snap connection at their ends 97, but are designed as continuous T-shaped webs which engage in cutouts 94 in the housing. The protective cap 90 is secured against detachment from the housing 12 via locking lugs 99 on the middle of the flat inner sides of the protective cap 90. The locking lugs 99 engage in corresponding recesses 100 in the region of the peripheral edge recess 92 of the housing and fix the protective cap in a barb-like manner. It is thus secured against being pulled off the housing, which further improves the blocking of the actuation button.
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. In order to be able to remove the protective cap, the user presses on the pressure surfaces 101 which indicate this actuation by means of appropriate corrugation. In this way, he presses the protective cap somewhat together, so that the barb-like locking lugs 99 are released from the recesses 100 by appropriate expansion of the oval profile of the protective cap, and the Protective cap can be removed.
