Das Medium wird dabei an einem Medienauslaß vom Spender abgelöst. Der Spender ist mit derselben einzigen Hand zu tragen und für den Medienaustrag zu betätigen. Als Austragförderer kann eine Pumpe, das Ventil eines Druckbehälters, wie eines Aerosolbehälters, o. dgl. vorgesehen sein. Das Medium kann am Medienauslaß zerstäubt oder als unzerstäubter Strahl bzw. Tropfen oder Strang abgegeben werden.The invention relates to a donor. With it, liquid, powdery, gaseous and / or pasty media ins Free are given. The medium becomes one Media outlet replaced by the donor. The donor is with to carry the same single hand and for media delivery to operate. A pump, the valve, can be used as the discharge conveyor a pressure container such as an aerosol container or the like be provided. The medium can be atomized at the media outlet or as an unsprayed jet or drop or strand be delivered.

Ein kleiner Spender mit einem axialen Betätigungshub von weniger als 5 mm oder 3 mm und einem größten Außendurchmesser von weniger als 25 mm, 20 mm oder 18 mm weist bevorzugt eine Handhabe auf, die nicht parallel zur Achse des Spenders, sondern quer dazu manuell zu drücken ist. Diese Bewegung der Handhabe wird in eine axiale Bewegung eines Betätigungs-Stößels umgewandelt. Bei solchen Spendern sind die einzelnen Bauteile sehr klein. Dadurch sind sie gegen mechanische Belastungen empfindlich sowie schwierig abzustützen. Weist der Spender über seine Länge eine unregelmäßige Außenfläche auf, die am Außenumfang oder im Griffbereich mehrfach abgestuft ist, so kann die Handhabung und Verstauung des Spenders in einer Tasche erschwert sein.A small dispenser with an axial stroke of less than 5 mm or 3 mm and a largest outside diameter of less than 25 mm, 20 mm or 18 mm preferably has one Handle that is not parallel to the axis of the dispenser, but to be pressed manually across it. This movement of the Handle becomes an axial movement of an actuating plunger converted. With such donors are the individual Components very small. This makes them against mechanical Stress sensitive and difficult to support. has the dispenser has an irregular outer surface over its length on, which are graduated several times on the outer circumference or in the handle area is, the handling and storage of the donor in one Bag be difficult.

Aus der US 4 132 359 ist ein Spender für Medien mit einem Grundkörper bekannt geworden, der eine Stirn aufweist und eine zentrale Achse bestimmt. Er hat einen Medienspeicher sowie als Austragsförderer eine Pumpe. Ihm ist eine Betätigungshandhabe in Form eines seitlichen schwenkbaren Hebels zugeordnet, die über eine Schrägfläche und einen Stift am Austragkopf die Pumpe betätigen kann. Die Betätigung des Hebels bringt eine erhebliche seitliche Kraft auf den Austragkopf und damit auf die Pumpe auf, was zu Verkantungen und damit Funktionsstörungen führen kann.From US 4 132 359 is a dispenser for media with a basic body become known, which has a forehead and a central axis certainly. It has a media store and one as a discharge conveyor Pump. It is an actuating handle in the form of a side assigned pivotable lever, which has an inclined surface and a The pump can actuate the pin on the discharge head. The actuation of the Lever brings considerable lateral force to the discharge head and thus on the pump, causing canting and malfunctions can lead.

It is intended to be easy to use and ergonomic ensure convenient handling.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Erfindungemäß sind Mittel vorgesehen, um den Stößel auf einer Länge radial und/oder gegen Verdrehung gesichert zu führen, die größer als die Hälfte des Stößel-Durchmessers sein kann. Die Stößel-Führung kann im Bereich der Kupplungsverbindung zwischen Handhabe und Stößel und/oder stromaufwärts unmittelbar daran anschließend vorgesehen sein. Die Führung erfolgt zweckmäßig unmittelbar am Innenumfang der äußersten Mantelwand des Grundkörpers. Der Führungsteil des Stößels kann einen Anschlag bilden für die betätigte Endstellung, die von der Ausgangsstellung entfernt ist. Dieser Anschlag kann an einer Stirnfläche des Gehäuses der Pumpe anschlagen, in welches der Stößel permanent hineinragt.According to the invention, means are provided to lengthen the plunger radially and / or secured against rotation, which is larger than can be half of the tappet diameter. The ram guide can in the area of the coupling connection between the handle and Tappet and / or upstream immediately thereafter provided his. The guidance is advisable directly on the inner circumference the outermost wall of the base body. The leadership part the plunger can form a stop for the actuated end position, which is distant from the starting position. This stop can occur on a Strike the end face of the pump housing into which the Ram permanently protrudes.

Der Spender weist beim Gebrauch über den größten Teil seiner Länge, insbesondere über mehr als zwei Drittel oder drei Viertel dieser Länge, konstante Außenweite auf. Diese Weite ist nur im Bereich des Austragkopfes reduziert. Über diese Weite steht nur die Handhabe radial nach außen vor. Die Gesamtlänge des Spenders ist mindestens fünf-, sieben- oder achtfach größer als seine Außenweite. Innerhalb der Länge mit konstanter Außenweite ist ein Medienspeicher mindestens um die Hälfte länger als der Grundkörper. Dieser konstant weite Außenumfang reicht über eine Länge von mindestens 8 cm oder 10 cm. So bildet der Außenumfang beim Betätigen eine günstige Griffläche. An ihr können alle Finger der Hand des Benutzers durch Umschließen abgestützt werden. Eine abnehmbare Akdeckung für den Austragkopf schließt mit der genannten Außenweite unmittelbar an den Grundkörper und die Handhabe an.The donor shows the majority of his use Length, especially over more than two thirds or three Quarter of this length, constant outside width. This vastness is only reduced in the area of the discharge head. About these Only the handle protrudes radially outwards. The Total length of the donor is at least five, seven or eight times larger than its outside width. Within the length with media coverage is at least around constant outside width half longer than the basic body. This constantly wide Outer circumference extends over a length of at least 8 cm or 10 centimeters. So the outer circumference forms a favorable when pressed Gripping surface. All fingers of the user's hand can be attached to it be supported by enclosing. A removable cover for the discharge head closes with the above Outside width directly to the body and the handle on.

Die genannte, konstant weite Umfangsfläche des stiftförmigen Spenders ist lediglich in Abschnitten unterbrochen, die eine Teillänge und einen Teilumfang des Grundkörpers einnehmen. In diesen Abschnitten ist die Umfangsfläche gegenüber den konstant weiten Bereichen quer versetzt. Diese Abschnitte können eine Fensteröffnung für den Eingriff der Handhabe, eine Schrägfläche für die betätigte Handhabe oder eine von der Handhabe abgekehrte, vertiefte Fingerkuhle sein.The aforementioned, constantly wide peripheral surface of the pin-shaped Spenders is only broken into sections, one Take up part of the length and part of the circumference of the body.

Von der Innenseite dieser Stirnwand erstreckt sich nur stromaufwärts ein gesonderter Düsenkern. Er bildet eine Baueinheit mit dem Stößel. Der Düsenkern liegt innerhalb der Kopfkappe auf dem größten Teil von deren Länge berührungsfrei. Der Stößel und der Kernkörper sind von einem Auslaßkanal durchsetzt. Er ist im Querschnitt von der Kreisform abweichend flach. Die Länge dieses Querschnittes ist gegenüber der Breite dieses Querschnittes um mindestens die Hälfte oder das Doppelte größer. Die Länge dieses Querschnittes ist mindestens so groß wie oder größer als die Außenweite des Kernkörpers. Der Kanal durchsetzt im Bereich der Schmalseiten seines Querschnittes eine äußere Stirnwand, von welcher der Kernkörper ausgeht. Außerdem bildet der Kanal am Außenumfang des Kernkörpers und im Anschluß an diese Stirnfläche Durchtrittsöffnungen. Durch sie kann das Medium vom Inneren des Kanales an den Außenumfang des Kernkörpers austreten.The discharge head has a one-piece, elongated cap on. It is in its end wall from a nozzle channel or the Media outlet penetrated. From the inside of this bulkhead a separate nozzle core extends only upstream. It forms a structural unit with the plunger. The nozzle core lies within the head cap on most of its length contact. The plunger and core are one Exhaust passage penetrated. It is circular in cross-section deviatingly flat. The length of this cross section is compared to the width of this cross section by at least that Half or double larger. The length of this cross section is at least as large as or larger than the outside width of the core body. The channel penetrates in the area of the narrow sides its cross section an outer end wall, of which the core body runs out of. In addition, the channel forms on Outer circumference of the core body and following this end face Passage openings. Through them the medium of Inside the channel to the outer periphery of the core body escape.

Die Öffnungen reichen bis zur Innenseite einer Stirnwand. Mit deren Außenseite liegt der Kernkörper unmittelbar benachbart zur Stirnwand der Kopfkappe bzw. zum inneren Endes des Düsenkanales. Von jeder Öffnung des Kernkörpers führt ein Axialkanal an die Außenseite der Stirnwand des Kernkörpers. Von dort ist ein Querkanal zum Düsenkanal gerichtet. Alle genannten Kanalabschnitte sind jeweils über den Umfang dicht geschlossen. Die Durchtritte des Kanales durch die Stirnwand und alle stromabwärts anschließenden Kanalabschnitte sind zweiteilig begrenzt, nämlich vom Stößel und von der Kopfkappe. Stromaufwärts davon und bis in den Druckraum der Pumpe liegt der Kanal vollständig innerhalb des Stößels. Dieser begrenzt den Kanal über den Umfang einteilig. So können kleinste Dosiermengen sehr genau ausgebracht und dabei feinst zerstäubt werden.The openings extend to the inside of a front wall. With the outside of the core body is immediately adjacent to the front wall of the head cap or to the inner end of the Jet channel. Introduces from each opening of the core body Axial channel to the outside of the end wall of the core body. From there, a cross channel is directed to the nozzle channel. All mentioned channel sections are each tight over the circumference closed. The passage of the canal through the front wall and are all downstream channel sections limited in two parts, namely by the plunger and the head cap. Upstream of it and into the pressure chamber of the pump the channel lies completely inside the tappet. This limits the channel in one piece over the circumference. So can Smallest dosing quantities applied very precisely and at the same time very fine be atomized.

Der Durchlaß 73 des Mitnehmers 16 ist vom Stößel 6, 40 durchsetzt. Diese Öffnung 73 ist langlochförmig. Die Breite dieses Langloches 73 liegt in der Schnittebene gemäß Fig. 2 und ist nahezu spielfrei an den zugehörigen Durchmesser des Abschnittes 40 angepaßt. Die Länge des Langlochquerschnittes 73 liegt in der dazu rechtwinkligen Schnittebene gemäß Fig. 1. In der Ausgangsstellung liegt das von der Handhabe 15 entfernte Ende des Langloches 73 parallel zur Achse 10. Dabei ist und das der Handhabe zugekehrte Ende in Richtung 13 von der Achse 10 weg spitzwinklig geneigt. Im Bereich des letzteren Endes liegen beiderseits vom Langloch 73 die schrägen Nocken 74. Sie gleiten an den Gegennocken 17. Der Vorsprung 68 weist eine Endfläche 76 auf. Sie ist als Schrägfläche in Richtung 13 konisch erweitert und liegt an der radialen Außenseite des Nockens 69. Wenn der Nocken 69 in den Ausschnitt 75 des Mantels 59 eingreift, bildet die Fläche 76 eine kontinuierliche Fortsetzung der gleichartigen End- oder Schrägfläche des Mantels 59.The driver 16 is in the views according to Figures 1 and 2 flat plate-shaped. It increases in thickness according to FIG. 1 only between the axis 10 and the handle 15 too. The passage 73 of the driver 16 is penetrated by the plunger 6, 40. This opening 73 is elongated. The width of this slot 73 lies in the sectional plane according to FIG. 2 and is almost free of play on the associated diameter of the section 40 adjusted. The length of the elongated hole cross section 73 is in the right-angled sectional plane according to FIG. 1. In the The starting position is that which is removed from the handle 15 End of the elongated hole 73 parallel to the axis 10. Here is and the end facing the handle in the direction 13 from the axis 10 inclined at an acute angle. In the area of the latter end the oblique cams 74 lie on both sides of the elongated hole 73. They slide on the counter cam 17. The projection 68 points an end surface 76. It is an inclined surface in the direction 13 extends conically and lies on the radial outside of the Cam 69. If the cam 69 in the cutout 75 of the Mantle 59 engages, the surface 76 forms a continuous Continuation of the similar end or inclined surface of the Coat 59.

In Richtung 13 kann gegen die Fläche 76 ein Gegenglied 77 axial gespannt werden. Es gibt radial federnd geringfügig nach. Das Gegenglied 77 geht ringförmig um die Achse 10 durch. Es ist daher in gleicher Weise gegen die Endfläche des Mantels 59 gespannt. Das Glied 77 schließt dieses Ende des Mantels 18 und die Einheit 4 dicht. Aus dem Inneren des Gliedes 77 steht über dessen stirnseitige Spannfläche in Richtung 13 ein hülsenförmiges Glied 78 vor. Es hat ein zweigängiges Außengewinde, das mit einem Innengewinde 79 des Mantels 59 zu verschrauben ist. Zum Verschrauben sowie zum Lösen genügt eine Drehung von höchstens 180° oder 90°. Der Innenumfang der Hülse 78 kann abgedichtet am Außenumfang des Mantels 58, 60 anliegen. Die Glieder 77, 78 können einteilig mit einem kappenförmigen Deckel 80 ausgebildet sein. Der nimmt den Kopf 9 einschließlich der Mäntel 58, 60 vollständig auf und schließt die Öffnung 20 dicht. Der Deckel 80 sperrt die Einheit 4 spielfrei gegen Betätigung und verspannt sie radial zur Achse 10 hin.In the direction 13, a counter member 77 can be against the surface 76 be axially clamped. There is slightly radial resilience to. The counter member 77 is ring-shaped about the axis 10 by. It is therefore in the same way against the end face of the Coat 59 stretched. Link 77 closes this end of the Jacket 18 and the unit 4 tight. From the inside of the Link 77 stands over its front clamping surface in Direction 13 a sleeve-shaped member 78 in front. It has a double-start external thread with an internal thread 79 des Mantle 59 is screwed. For screwing as well as Loosening is sufficient for a rotation of at most 180 ° or 90 °. The Inner circumference of the sleeve 78 can be sealed on the outer circumference of the Coat 58, 60 fit. The links 77, 78 can be in one piece be formed with a cap-shaped cover 80. The takes the head 9 including the coats 58, 60 completely opens and closes the opening 20 tightly. The lid 80 locks the unit 4 without play against actuation and braced it radial to axis 10.

Nach Abnahme des Deckels 80 wird die Handhabe 15 in Richtung 14 durch Fingerdruck betätigt. Dabei wird der Nocken 69 entschnappt. Dadurch bewegt sich der Stößel 6 sofort in Richtung 13 und der Kolben 28 setzt das die Kammer 26 ausfüllende Medium unter Druck. Dadurch wird das Ventil 25 in Schließlage verspannt. Nach einem Axialhub zwischen 2 mm und 3 mm öffnet das Ventil 32. Das Medium strömt dann zwischen Kolben 28 und Kern 29 in Richtung 12 in die Stößelabschnitte. Erst an den Öffnungen 15, 51 tritt das Medium axial sowie radial aus dem Stößel 6 aus. Das Medium wird dann innerhalb der Kammer 55 in Rotation versetzt und danach an der Begrenzungskante der Öffnung 20 zerstäubt. Auf dem letzten Teilweg des Hubes ergibt sich zusätzlich zur progressiven Kraft einer Rückstellfeder 81 eine steiler ansteigende Betätigungskraft, weil die Flügel der Handhabe 15 am Umfang 63 aufgeweitet werden müssen. Die Feder 81 liegt innerhalb der Kammer 26 und ist am Kern 29 permanent mit axialer Vorspannung abgestützt. Am Ende des Hubes schließt das Ventil 32 wieder selbsttätig. Nach Freigabe heben die rückfedernden Flügel die Handhabe 15 mit den Nocken 74 zunächst vom Glied 17 ab. Gleichzeitig stellt die Feder 81 die Einheit 3 und auch die Einheit 4 zur anschlagbegrenzten Ausgangslage zurück. Hierbei öffnet das Ventil 25 durch Unterdruck in der Kammer 26. Daher wird bei geschlossenem Ventil 32 über den Kanal 24 aus dem Speicher 7 Medium in die Kammer 26 angesaugt. After removing the cover 80, the handle 15 is in the direction 14 operated by finger pressure. The cam 69 entschnappt. As a result, the plunger 6 moves in immediately Direction 13 and the piston 28 sets that filling the chamber 26 Medium under pressure. This causes the valve 25 in Clamped position. After an axial stroke between 2 mm and The valve 32 opens 3 mm. The medium then flows between Piston 28 and core 29 in direction 12 in the tappet sections. Only at the openings 15, 51 does the medium occur axially and radially out of the plunger 6. The medium is then inside the chamber 55 rotated and then at the boundary edge the opening 20 atomized. On the last part of the way of the stroke results in addition to the progressive force Return spring 81 a steeply increasing actuating force, because the wings of the handle 15 widened on the circumference 63 Need to become. The spring 81 lies within the chamber 26 and is permanently supported on the core 29 with axial preload. At the end of the stroke, the valve 32 closes again automatically. After release, the resilient wings lift the handle 15 with the cams 74 initially from the link 17. simultaneously the spring 81 provides the unit 3 and also the unit 4 limited starting position. This opens the Valve 25 by negative pressure in the chamber 26. Therefore at closed valve 32 via channel 24 from memory 7 Medium sucked into the chamber 26.
