Definitions

  • the invention relates to a dispenser according to the preamble of claim 1.
  • DE-OS 36 05 419 proposes captive assignment of a closing means to a portioning version.
  • the actuating handle which can be displaced against a spring force, carries a sliding cover. In the basic position of the dispenser, this can then be pushed over the outlet opening of the dispensing tube which is stationary there.
  • a side effect is achieved in that the relocation of the actuating handle is blocked when the dispenser is closed.
  • This solution also depends on the user's mindfulness. If the latter forgets to move the sliding lid into the closed position, it will dry out too, forming an increasingly harder plug.
  • DE-OS 35 07 355 proposes a self-closing mechanism. Specifically, the procedure is such that the dispensing tube displaceable in the axial of the dispenser housing has a transverse axis on which a toggle button sits, which forms a slide with its free end, which is moved when actuated from the cross-sectional area of the outlet opening. The corresponding actuation takes place against spring force, which shifts the closing element back into its basic closing position when released.
  • the object of the invention is to make a generic dispenser more reliable in terms of use in this regard, without sacrificing the advantage of the self-closing function, and which above all also works more powerfully or more spontaneously.
  • a generic dispenser of increased utility value is achieved: the release conditions are triggered by the pressure conditions of the filling material. This brings great independence from its viscosity. Only the ready-to-open position is checked via the actuating handle. Specifically, the procedure is such that the dispensing tube is guided so that it can move in a linear manner in the actuating handle, the outlet opening being retracted behind a closure part in the unactuated position and, when actuated, the compression pressure causes the closure tube to extend.
  • the opposing shift from dispensing tube to actuating handle can be used not only to shorten the stroke, but also for the time factor; it comes for faster dispensing and clean, powerful ejection of the pasty mass.
  • the tube is practically "floating” or “free-floating” and can thus - subject to the free play of forces - adjust individually to the given conditions (friction, pressure).
  • the closing part is integrally formed on the actuating handle and the dispensing tube is guided in the actuating handle which is linearly movable in a stop-limited manner.
  • the inlet opening of the movable dispensing tube can be lifted off from a closing valve which is fixed to the housing or is formed on the actuating handle. The latter works extremely spontaneously and avoids emptying, so that there is always a portion of the mass that is always ready to be spent.
  • an advantageous embodiment with regard to the displacement of the delivery tube is that the delivery tube is surrounded at a radial distance by a guide sleeve and that the annular space created in this way is closed by a circumferential piston wall molded onto the delivery tube.
  • the piston means are housed in a very small space, using the already existing axial length of the dispensing tube, with favorable conditions regarding the support on the guide sleeve for the clean, low-friction mounting of the dispensing tube therein.
  • the dispenser mechanism can also be realized in the context of a pump chamber, be it with a bellows or pump piston.
  • the pump chamber is designed with an inlet valve and an outlet valve, the outlet valve can be opened on its guide surface with stop lugs and the outlet valve which is arranged displaceably inside the dispensing tube is connected to an inlet valve.
  • the illustrated dispenser of the exemplary embodiments has a long, cylindrical housing 1. Its base 2, which is designed as a standing surface, is spherically drawn in, so that there is a peripheral standing edge 3.
  • the end of the housing 1 opposite the bottom 2 has a flange 4 following a neck portion 5 that is drawn in significantly behind the diameter of the housing.
  • the housing 1 there is a previously introduced, cup-shaped piston 6. Its lip 6 'lead on the cylindrical housing inner wall 1'.
  • the floor 2 has a central opening 7 for air compensation.
  • a central protrusion 8 of the piston 6 projects into it, initially sealingly.
  • the protrusion 8 extends from the bottom of the cup-shaped piston 6 and is hollow.
  • the protruding area of the projection has the shape of a truncated cone, which on the inside of the housing merges into an annular shoulder which rests on the opening edge.
  • the upward end region of the housing 1 opposite the base 2 is equipped with a device V for dispensing the dispenser contents in portions.
  • a device V for dispensing the dispenser contents in portions.
  • the content of the donor it may be pasty mass M, such as toothpaste.
  • Part of the device V is a pump chamber 9. This has a bellows 10 which is compressible in the longitudinal center axis xx of the dispenser and is supported at the bottom. This forms a cylindrical one Ring groove 14 with rotationally symmetrically converging inlet flanks 14 '.
  • the insert body 13 is, overlapping the conveyor rim 4 of the housing 1, essentially in the interior of the housing 1.
  • the overlap is realized as a sealing bounce or snap-in connection, for which purpose the upper edge of the essentially cylindrical insert body 13 is in an overlapping, flat annular flange 15 continues with subsequent axially oriented locking lip 16. Seen in cross section, there is a groove-forming contour. This locking groove bears the reference number 17.
  • Another ring collar 18 facing away from the piston is connected to a movable component of the device. It is a head piece 19 which can be displaced in the interior of the insert body 13 and is guided in a limited manner in the longitudinal central axis xx. This also essentially cylindrical shape, is in the dispenser closed position about a third of its length in the cylindrical cavity of the insert body 13. This overlap area is for Guidance and limit stop used.
  • the lower edge of the head piece 19 has an outwardly directed guide rib 20 and a locking rib 21 formed on its cylindrical outer surface, spaced apart from the guide rib 20, which in the basic position occurs against a flange-like counter rib 22 of the insert body 13.
  • the supporting system results from the restoring force of the bellows 10, which is embedded with a certain preload.
  • the ring collar 18 enters the ring groove 23 of the movable head piece 19 in a position-secured manner.
  • the latter and the insert body form the pump housing of the device V.
  • a helical compression spring would be used to secure the basic position of the dispenser.
  • the head piece 19 has an easily accessible actuation handle B.
  • the latter consists of a cover plate 24 which closes off a portion of the cylindrical head piece 19.
  • the latter is plugged into the head piece 19 in a plug-like manner and covers the free end of an output tube which forms the heart of the dispensing mechanism at the top y 25.
  • the latter is angular. It has a vertical tube section a running in the longitudinal central axis x-x and a radially directed tube section b extending at a right angle.
  • the dispensing tube 25 is guided linearly in the actuation handle B.
  • a guide sleeve 26 of cylindrical shape is used for this purpose. It is molded onto the head piece 19 and arises from a transverse wall 27 of the head piece 19 which forms the annular groove 23.
  • the guide sleeve 26 which runs concentrically to the cylindrical wall of the head piece 19, ends at the level of the underside of the tube section b. Equal in height to this also closes a window edge 28 'formed by the head piece 19' of a window 28 open towards the transverse side, from which window edge 28 'the dispensing tube 25 is supported in a stop-limited manner.
  • the leading inside of the guide sleeve 26 runs circumferentially at a radial distance z to the outer wall of the Tube section a.
  • the annular space 29 thus present is cross-closed by a piston wall 30.
  • This piston wall there is an annular lip with a bevel on the piston side, so that the plug-in assembly is facilitated.
  • the piston wall 30 running continuously on a cross-sectional plane is in the basic position in the lower third of the longer tube section a.
  • the support is provided via longitudinal ribs 31, which are arranged in a star shape on the lateral surface of said tube section, at least three in number.
  • the end faces of the longitudinal ribs are chamfered, ie beveled, to improve the sliding ability.
  • the piston-side inlet opening 25 'of the dispensing tube 25 overlaps a closing valve 32 which is fixed to the housing in the present case. It is a stopper-like expression of the transverse wall 27 directed towards the inside of the tube movable part, namely on the actuating handle B, that is to say the head piece 19 and the associated valve seat surface also on a part movable relative thereto, namely the dispensing tube 25.
  • the closing valve 32 stationary, for example on an extension arm of the housing 1 to store.
  • the transverse wall 27 carrying the closing valve 32 is broken.
  • the opening begins at the plug base of the closing valve 32 and extends in shape a plurality of radial slots 33 in the direction of the annular groove 23 without naturally affecting it.
  • An inlet valve V 1 is then located in the bottom 12 of the insert body 13.
  • This is designed as a valve plate, the valve seat surface of which extends from the end edge of a collar 34 that licks out in the direction of the pump chamber 9.
  • the stop lugs 36 formed over these define the valve lift and thus bind the valve body in the cylindrical collar 34.
  • the inlet valve V 1 and the closing valve 32 which can also be referred to as an outlet valve, control the mass flow in portions.
  • the inlet valve V 1 is designed in the same way as the inlet valve V 1 of the first embodiment. However, it sits over an axial shaft 37 in the exhaust valve V 2 continues. The latter is located inside the dispensing tube 25. In the basic position, the outlet valve V 2 is located approximately at the level of the piston wall 30.
  • the outlet valve V 2 consists of two valve flaps 37 'starting from the head of the shaft and having the same area size. When flowing through the mass, the two valve flaps 37 'fold together practically like a book page (see FIG. 5).
  • the valve flaps assume a Y-shape in the sealing position, i. H. the valve flaps diverge upwards. In this position, they assume an edge-tight contact with the inner surface of the dispensing tube 25.
  • the valve flaps 37 ' can be slightly tapered towards the free ends and are made of flexible material with sufficient restoring force.
  • the outlet opening O has moved behind a stationary closure part 38 (cf. FIGS. 1 and 4).
  • this closure part 38 is a vertical wall section of the head piece 19, and shown that the part of the wall forming the closure part 38 forms a flat surface 38 'on the inside, which runs parallel to the end face 39 of the tube section b.
  • the upper front edge is designed to a cutting edge 38 ⁇ .
  • the vertical wall section forming the actual closure part 38 continues via at least one approximately radially directed side wall 40 into the cylindrical jacket wall of the head piece 19.
  • two side walls 40 are expediently formed, which, coordinated with the outer diameter of the tube section b, create a vertical guide shaft 41.
  • the leadership shaft 41 is left open at the bottom. As a result, paste residues cannot lead to a shortening of the vertical movement stroke of the dispensing tube 25.
  • the guide shaft 41 merges into the window 28 of the head piece 19. In the actuating position, however, the horizontal tube section b does not leave the guide shaft 41, since its side walls 40 continue to rise obliquely upwards beyond the upper edge of the cutting edge 38 ⁇ .
  • a soft spring 42 is located in the area of the distance y above the tube section b. It is, for example, an inclined leaf spring. This is either molded onto the top of the tube section b in the manner of a cock's comb, or else the inside of the corresponding cover side of the cover plate 24 is injection molded.
  • the housing 1 can also hold liquid, in which case a riser pipe, not shown, would then emanate from the bottom 12 of the insert body 13.
  • the insert 19 would have a small passage opening for the necessary air balance, expediently in the area of the collar 11, which could take over valve function. The hole would then lie in the area of the said collar which is not contained.
  • the actuating handle B forms in the center of the cover plate 24 a small pin 43 which projects upwards therefrom.
  • the finished, filled product has a dispenser protective cap 44 covering the mechanics.
  • the edge thereof has a tamper-evident device 45 in the form of a ring which engages under the locking lip 16.
  • a notch groove 46 (FIG. 2).
  • the ring has a pull tab, not shown.
  • the top-side support of the protective cap 44 form on the inner wall of the cup-shaped cap body formed longitudinal ribs 47, which rest on the flat ring flange 15 with their underside.
  • the function is as follows: After removing the protective cap 44, the actuating handle B is accessible. Applying pressure in the direction of arrow P leads to a reduction in the volume in the pump chamber 9 due to the pump bellows 10 being compressed when the discharge path is already filled Pressure device.
  • This shooting up of the dispensing tube 25 firstly removes the closed position of the dispensing tube by moving its outlet opening ⁇ out of the area of the closing part 38, and secondly opens the closing valve 32, since the relevant inner end section 25 ', i.e. the inlet opening of the dispensing tube stands out from it.
  • the actuating handle B or the head piece 19 is moved downward relative to the stationary insert body 13, the inlet valve V 1 remains closed due to the compression pressure in the pump chamber 9.
  • the tube section b which has moved upward by the distance y, has entered a complete release position so that the strand of the pasty mass is applied cleanly. This happens due to the increasing compression pressure and the spontaneous, overlaying pushing of the dispensing tube 25 in the opposite direction, it is also quite rapid. If the actuation button B is released after the application, the spring force of the bellows causes the return to the closed position, ie the head piece 19 extends again. This results in a vacuum in the pump chamber 9, which vacuum lifts the inlet valve V 1 from its valve seat surface, so that paste-like mass M is sucked into the pump chamber 9 from the supply. The piston 6 is pulled over the level column by the corresponding volume fraction.
  • the inlet valve V 1 does not even have to step into its closed position, which is conceivable taking into account the frictional forces and the pasty mass, so that even a constant moisture connection of the portion enclosed in the pump chamber 9 to the residual mass M in the housing 1 is given.
  • the piston 6 has a structure which ensures that the pasty mass is dispensed as completely as possible.
  • the function of the dispenser according to the second embodiment (Fig. 4 and 5) is essentially the same, both in terms of the self-closing effect and the output, only that when output by the scoop-like function of the exhaust valve V 2, a portion of the strand relative is pushed out for tube movement, since this outlet valve V2 is connected via the shaft 37 to the inlet valve V1 which has entered its closed position.

Abstract

The dispenser for pasty masses has an insert part (13) with a bottom (12), in which an actuating handle (B1) is guided displaceably. Said actuating handle (B1) is connected to a discharge pipe (25). Arranged between the bottom (12) and the actuating handle (B1) is a bellows (10), which produces a spring force and surrounds a pump space (9). Arranged in the bottom (12) is an inlet valve (V1) which is connected to an outlet valve (V2) in the discharge pipe (25). In the case of pressure on the actuating handle (B1), the pasty mass present in the pump space (9) emerges via the discharge pipe (25) with the outlet valve (V2) opening while the inlet valve (V1) is kept closed. In the case of the actuating handle (B1) being released, the outlet valve (V2) closes while the inlet valve (V1) opens so that pasty mass from the container (1) can flow into the pump space (9). <IMAGE>

Description

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

Um dem Antrocknen des unmittelbar ausgabebereiten Anteils beispielsweise pastöser Massen zu wehren, sind schon viele Vorkehrungen getroffen worden. Der diesbezügliche klassische Vorschlag besteht in der Verwendung einer Schraubkappe, die auf den tüllenartigen Spenderhals auf­geschraubt wird, wobei Hals das entsprechende Gegengewinde aufweist (US-PS 3,768,705). Nachteilig ist hier jedoch, daß es allzu häufig unterlassen wird, die Schraubkappe ordnungsgemäß wieder aufzuschrauben. So entsteht jedes­mal ein nicht verwendbarer, eingedickter Strangabschnitt an pastöser Masse.Many measures have already been taken to prevent the portion of paste-like masses that are ready to be dispensed from drying on. The classic proposal in this regard consists in the use of a screw cap which is screwed onto the spout-like dispenser neck, the neck having the corresponding counter thread (US Pat. No. 3,768,705). The disadvantage here, however, is that it is all too often omitted to properly screw the screw cap back on. In this way, an unusable, thickened strand section of pasty mass is created each time.

Um die diesbezüglichen Sicherungsmittel gegen Antrocknen möglichst unter Bildung eines unverlierbaren Bauteiles zu realisieren, existiert auch bereits der Vorschlag eines sogenannten Lippenventils (US-PS 2 898 007). Es handelt sich dort um eine Art Schnabeltülle aus flexi­blem Material. Der Tüllenmund ist durch einen Spaltschnitt gebildet. Die Rückstellkraft des Materiales hält das so geschaffene Mundstück geschlossen. Wird Überdruck erzeugt, preßt sich ein schmaler Strang aus, wobei die Lippen auseinanderklaffen. Läßt der zur Ausgabe führende Druck nach, pressen sich die Lippen schließend wieder gegeneinander. Diese Lösung hat nach Nachteil der ungleich­mäßigen Portionierung. Man kann unter Quetschen des Be­hälterkörpers, der aus entsprechend flexiblem Material besteht, in einem Zug praktisch den gesamten Inhalt aus­bringen.In order to implement the relevant anti-drying agent as far as possible with the formation of a captive component, there is already a proposal for a so-called lip valve (US Pat. No. 2,898,007). It is a kind of beak nozzle made of flexible material. The spout mouth is formed by a split cut. The restoring force of the material keeps the mouthpiece closed. If overpressure is created, a narrow strand is pressed, with the lips gaping apart. If the pressure leading to the release subsides, the lips press against each other again. This solution has the disadvantage of uneven portioning. You can squeeze out the container body, which consists of a correspondingly flexible material, to practically all of the contents in one go.

Aus der DE-OS 30 44 439 existiert an einem die portions­weise Ausgabe ermöglichenden Spender der Vorschlag, die Austrittsöffnung durch die Innenwandung einer den Spender­ kopf überfangenden, aufsteckbaren Schutzkappe abzudichten. Die Verhinderung des Antrocknens des unmittelbar ausgabe­bereiten Vorrats hängt aber auch hier wiederum von der zuverlässigen Handhabung des Benutzers ab. Geht die Schutz­kappe verloren, kommt es zu den erläuterten Nachteilen.From DE-OS 30 44 439 there is a proposal on a dispenser which enables dispensing in portions, the outlet opening through the inner wall of the dispenser to seal the head-overlapping, attachable protective cap. The prevention of drying of the immediately ready-to-dispense stock also depends on the reliable handling of the user. If the protective cap is lost, the disadvantages explained arise.

Eine unverlierbare Zuordnung eines Schließmittels an einer portionierenden Version bringt die DE-OS 36 05 419 in Vorschlag. Dort trägt die entgegen einer Federkraft verlagerbare Betätigungshandhabe einen Schiebedeckel. Dieser kann in Grundstellung des Spenders schließend über die Austrittsöffnung des dort ortsfesten Ausgabe­röhrchens geschoben werden. Erreicht ist ein Nebeneffekt dahingehend, daß bei verschlossenem Spender die Verlagerung der Betätigungshandhabe blockiert ist. Diese Lösung ist aber auch auf die Achtsamkeit des Benutzers angewiesen. Wenn dieser nämlich vergißt, den Schiebedeckel in die Schließstellung zu verlagern, kommt es auch hier zum Antrocknen unter Bildung eines zunehmend härteren Propfens.DE-OS 36 05 419 proposes captive assignment of a closing means to a portioning version. There, the actuating handle, which can be displaced against a spring force, carries a sliding cover. In the basic position of the dispenser, this can then be pushed over the outlet opening of the dispensing tube which is stationary there. A side effect is achieved in that the relocation of the actuating handle is blocked when the dispenser is closed. This solution also depends on the user's mindfulness. If the latter forgets to move the sliding lid into the closed position, it will dry out too, forming an increasingly harder plug.

Schließlich existiert durch die DE-OS 35 07 355 der Vor­schlag einer selbstschließenden Mechanik. Konkret ist dort so vorgegangen, daß das in der Axialen des Spender­gehäuses verlagerbare Ausgaberöhrchen eine Querachse besitzt, auf der eine Kipptaste sitzt, welche mit ihrem freien Ende einen Schieber bildet, der bei Betätigung aus dem Querschnittsbereich der Austrittsöffnung verla­gert wird. Die entsprechende Betätigung geschieht entgegen Federkraft, welche das Schließorgan unter Loslassen wieder in seine Schließgrundstellung verlagert. Die Frei­gabe der Austrittsöffnung geschieht in Bezug auf den Austritt der pastösen Masse vorrangig, wozu der Kipphebel erst eine neutrale Winkelzone durchläuft, die diesem Freigabemaß entspricht, um dann erst in Art einer Abstemm­ bewegung zum ortsfesten Kopfteil des Spendergehäuses die Vertikalverlagerung eines Kolbens vorzunehmen. Es liegt also eine zwangsweise Abfolge von Bewegungen vor, was zu einer nicht unerheblichen Verzögerung im Hinblick auf die Ausgabe des Gutes führt, mit anderen Worten, die Ausgabe ist nicht schnell genug. Außerdem besteht eine relativ große Abhängigkeit von dem Viskositätsgrad der auszugebenden Masse.Finally, DE-OS 35 07 355 proposes a self-closing mechanism. Specifically, the procedure is such that the dispensing tube displaceable in the axial of the dispenser housing has a transverse axis on which a toggle button sits, which forms a slide with its free end, which is moved when actuated from the cross-sectional area of the outlet opening. The corresponding actuation takes place against spring force, which shifts the closing element back into its basic closing position when released. The release of the outlet opening takes place primarily in relation to the outlet of the pasty mass, for which purpose the rocker arm first passes through a neutral angular zone which corresponds to this release dimension, only then in the manner of a stripping movement to the stationary head part of the dispenser housing to carry out the vertical displacement of a piston. So there is a compulsory sequence of movements, which leads to a not inconsiderable delay in the delivery of the goods, in other words, the delivery is not fast enough. In addition, there is a relatively large dependence on the degree of viscosity of the mass to be dispensed.

Aufgabe der Erfindung ist es, einen gattungsgemäßen Spender diesbezüglich gebrauchszuverlässiger auszubilden, ohne auf den Vorteil der Selbstschlußfunktion zu ver­zichten, und der vor allem auch kraftvoller bzw. sponta­ner arbeitet.The object of the invention is to make a generic dispenser more reliable in terms of use in this regard, without sacrificing the advantage of the self-closing function, and which above all also works more powerfully or more spontaneously.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merk­male des Anspruches 1. Die Unteransprüche sind vorteilhaf­te Weiterbildungen des erfindungsgemäßen Spenders.This object is achieved by the characterizing features of claim 1. The subclaims are advantageous developments of the dispenser according to the invention.

Zufolge solcher Ausgestaltung ist ein gattungsgemäßer Spender von erhöhtem Gebrauchswert erzielt: Auslöser für die Freigabesteuerung sind die Druckverhältnisse des Füllguts. Das bringt eine große Unabhängigkeit von der Viskosität desselben. Über die Betätigungshandhabe wird nur mehr die Öffnungsbereitschaftsstellung kontrolliert. Konkret ist dabei so vorgegangen, daß das Ausgaberöhrchen linear in der Betätigungshandhabe anschlagbegrenzt be­weglich geführt ist, wobei die Austrittsöffnung in der unbetätigten Stellung hinter ein Verschlußteil einge­fahren ist und bei Betätigung durch den Komprimierungs­druck das Ausfahren aus der Verschlußlage bewirkt wird. Hierbei läßt sich die gegenläufige Verlagerung von Aus­gaberöhrchen zu Betätigungshandhabe nicht nur hubver­kürzend nutzen, sondern auch für den Zeitfaktor; es kommt zu einer schnelleren Ausgabe und sauberem, kraftvollem Ausstoß der pastösen Masse. So gesehen ist das Röhrchen praktisch "schwimmend" bzw. "freifliegend" gelagert und kann sich so - dem freien Spiel der Kräfte ausgesetzt - individuell auf die gegebenen Verhältnisse (Reibung, Druck) einstellen. Dabei ist es günstig, daß das Verschließ­teil an die Betätigungshandhabe angeformt ist und das Ausgaberöhrchen in der desgleichen anschlagebegrenzt linear beweglichen Betätigungshandhabe geführt ist. Da­rüberhinaus wird vorgeschlagen, daß die Eintrittsöffnung des beweglichen Ausgaberöhrchens von einem gehäusefesten oder einem an der Betätigungshandhabe angeformten Schließ­ventil abhebbar ist. Letzteres wirkt äußerst spontan und vermeidet ein Entleeren, so daß ein stets ausgabebe­reiter Anteil an Masse entsteht. Außerdem ergibt sich im vorratsseitigen Endbereich des Ausgaberöhrchens über das Verschlußteil hinaus eine zweite Dichtstelle, die selbst bei längsten Lagerzeiten ein Durchtrocknen bis in den Vorrat hinein vermeidet. Unter der üblichen Be­tätigung bleibt dagegen der erforderliche Feuchteanschluß an den Vorrat erhalten. Eine im Hinblick auf die Ausga­berährchen-Verlagerung vorteilhafte Ausgestaltung be­steht darin, daß das Ausgaberöhrchen mit radialem Abstand von einer Führungshülse umgeben ist und daß der so ge­schaffene Ringraum durch eine an das Ausgaberöhrchen angeformte, umlaufende Kolbenwand verschlossen ist. Die Kolbenmittel sind auf engstem Raum untergebracht, dies unter Nutzung der ohnehin vorhandenen axialen Länge des Ausgaberöhrchens, wobei sich im Hinblick auf die Abstützung an der Führungshülse günstige Voraussetzungen ergeben für die saubere, reibungsarme Lagerung des Ausgaberöhr­chens darin. Die durch Betätigung unter Druck geratene Masse schießt das Röhrchen aus der Verschlußstellung frei. Obwohl im Hinblick auf die Ausgabe des pastösen Inhalts auf das Prinzip des hydraulischen Spenders ab­gestellt sein kann, mit rücklaufgesperrtem Nachlaufkolben etc., läßt sich die Spendermechanik auch im Rahmen einer Pumpenkammer realisiseren, sei es mit Balg oder Pumpen­kolben. In letzterem Sinne erweist es sich als vorteilhaft, daß die Pumpenkammer mit einem Einlaßventil und einem Auslaßventil ausgebildet ist, das Auslaßventil an seiner Führungsfläche ausgebildete Anschlagnasen anschlagbe­grenzt öffenbar ist und das verschiebbar im Inneren des Ausgaberöhrchens angeordnete Auslaßventil mit einem Ein­laßventil verbunden ist. Dies führt dazu, daß sich der Ausgabestrang aus einem ausgehobenen Abschnitt und einem ventilumspülten, aus der Verdrängung bzw. Komprimierung herrührenden Abschnitt aus der Pumpenkammer zusammensetzt. Die schließlich noch getroffene bauliche Maßnahme, daß das Ausgaberöhrchen gegen eine Feder aus seiner Verschluß­stellung ausfahrbar ist, führt zu einem bei genügendem Druck überschreitbaren Gegenhalt für das Ausgaberöhrchen und damit kraftvollen Ausstoß der pastösen Masse.As a result of such a configuration, a generic dispenser of increased utility value is achieved: the release conditions are triggered by the pressure conditions of the filling material. This brings great independence from its viscosity. Only the ready-to-open position is checked via the actuating handle. Specifically, the procedure is such that the dispensing tube is guided so that it can move in a linear manner in the actuating handle, the outlet opening being retracted behind a closure part in the unactuated position and, when actuated, the compression pressure causes the closure tube to extend. Here, the opposing shift from dispensing tube to actuating handle can be used not only to shorten the stroke, but also for the time factor; it comes for faster dispensing and clean, powerful ejection of the pasty mass. Seen in this way, the tube is practically "floating" or "free-floating" and can thus - subject to the free play of forces - adjust individually to the given conditions (friction, pressure). It is advantageous that the closing part is integrally formed on the actuating handle and the dispensing tube is guided in the actuating handle which is linearly movable in a stop-limited manner. In addition, it is proposed that the inlet opening of the movable dispensing tube can be lifted off from a closing valve which is fixed to the housing or is formed on the actuating handle. The latter works extremely spontaneously and avoids emptying, so that there is always a portion of the mass that is always ready to be spent. In addition, in the end region of the dispensing tube on the supply side, there is a second sealing point beyond the closure part, which prevents drying out even in the longest storage times, even into the supply. On the other hand, the required moisture connection to the supply is retained under normal operation. An advantageous embodiment with regard to the displacement of the delivery tube is that the delivery tube is surrounded at a radial distance by a guide sleeve and that the annular space created in this way is closed by a circumferential piston wall molded onto the delivery tube. The piston means are housed in a very small space, using the already existing axial length of the dispensing tube, with favorable conditions regarding the support on the guide sleeve for the clean, low-friction mounting of the dispensing tube therein. The mass, which is pressurized, shoots the tube free from the closed position. Although with regard to the output of the pasty Content can be based on the principle of the hydraulic dispenser, with a non-return piston, etc., the dispenser mechanism can also be realized in the context of a pump chamber, be it with a bellows or pump piston. In the latter sense, it proves to be advantageous that the pump chamber is designed with an inlet valve and an outlet valve, the outlet valve can be opened on its guide surface with stop lugs and the outlet valve which is arranged displaceably inside the dispensing tube is connected to an inlet valve. This leads to the output line being composed of a lifted section and a valve-washed section from the pump chamber resulting from the displacement or compression. The structural measure finally taken that the dispensing tube can be extended out of its closed position against a spring leads to a counterforce that can be exceeded with sufficient pressure for the dispensing tube and thus powerful discharge of the pasty mass.

Der dargestellt Spender der Ausführungsbeispiele be­sitzt ein lang zylindrisch ausgebildetes Gehäuse 1. Dessen als Standfläche gestalteter Boden 2 ist sphärisch eingezogen, so daß ein peripherer Standrand 3 vorliegt.The illustrated dispenser of the exemplary embodiments has a long, cylindrical housing 1. Its base 2, which is designed as a standing surface, is spherically drawn in, so that there is a peripheral standing edge 3.

Das dem Boden 2 gegenüberliegende Ende des Gehäuses 1 besitzt einen Börderlrand 4 im Anschluß an eine deut­lich hinter den Durchmesser des Gehäuses eingezogene Halspartie 5.The end of the housing 1 opposite the bottom 2 has a flange 4 following a neck portion 5 that is drawn in significantly behind the diameter of the housing.

Im Gehäuse 1 befindet sich ein zuvor eingebrachter, topfförmiger Kolben 6. Dessen Randlippen6′ führen sich an der zylindrischen Gehäuseinnenwandung 1′. Zum Luft­ausgleich weist der Boden 2 eine zentrale Durchbrechung 7 auf. In diese ragt, anfangs abdichtend, ein zentraler Vorsprung 8 des Kolbens 6. Der Vorsprung 8 geht vom Boden des topfförmigen Kolbens 6 aus und ist hohl ausge­bildet. Der hindurchragende Bereich des Vorsprunges weist Kegelstumpfform auf, welche gehäuseinnenseitig in eine Ringschulter übergeht, die am Durchbrechungs­rand anliegt.In the housing 1 there is a previously introduced, cup-shaped piston 6. Its lip 6 'lead on the cylindrical housing inner wall 1'. The floor 2 has a central opening 7 for air compensation. A central protrusion 8 of the piston 6 projects into it, initially sealingly. The protrusion 8 extends from the bottom of the cup-shaped piston 6 and is hollow. The protruding area of the projection has the shape of a truncated cone, which on the inside of the housing merges into an annular shoulder which rests on the opening edge.

Der dem Boden 2 gegenüberliegende, nach oben gerichtete Endbereich des Gehäuses 1 ist mit einer Vorrichtung V zur portionsweisen Ausgabe des Spenderinhalts ausge­stattet. Bezüglich des Spenderinhalts kann es sich um pastöse Masse M, wie bspw. Zahnpasta, handeln.The upward end region of the housing 1 opposite the base 2 is equipped with a device V for dispensing the dispenser contents in portions. With regard to the content of the donor, it may be pasty mass M, such as toothpaste.

Bestandteil der Vorrichtung V ist eine Pumpenkammer 9. Diese besitzt einen in der Längsmittelachse x-x des Spenders zusammendrückbaren, unten abgestütztem Falten­balg 10. Ein kolbenseitiger Ringbund 11 des Faltenbal­ges 10 ist abgedichtet am Boden 12 eines Einsatzkör­pers 13 befestigt. Dieser formt dazu eine zylindrische Ringnut 14 mit nutseitig rotationssymmetrisch konver­gierenden Einlaufflanken 14′.Part of the device V is a pump chamber 9. This has a bellows 10 which is compressible in the longitudinal center axis xx of the dispenser and is supported at the bottom. This forms a cylindrical one Ring groove 14 with rotationally symmetrically converging inlet flanks 14 '.

Der Einsatzkörper 13 steckt, den Börderlrand 4 des Ge­häuses 1 übergreifend, im wesentlichen im Inneren des Gehäuses 1. Der Übergriff ist als dichtende Prell- oder Rastverbindung realisiert, wozu sich der obere Rand des im wesentlichen zylindrisch gestalteten Einsatz­körpers 13 in einen übergreifenden, ebenen Ringflansch 15 fortsetzt mit anschließender axial orientierter Rast­lippe 16. Im Querschnitt gesehen liegt eine nutbildende Kontur vor. Diese Rastnut trägt das Bezugszeichen 17.The insert body 13 is, overlapping the conveyor rim 4 of the housing 1, essentially in the interior of the housing 1. The overlap is realized as a sealing bounce or snap-in connection, for which purpose the upper edge of the essentially cylindrical insert body 13 is in an overlapping, flat annular flange 15 continues with subsequent axially oriented locking lip 16. Seen in cross section, there is a groove-forming contour. This locking groove bears the reference number 17.

Ein anderer, kolbenabgewandter Ringbund 18 ist mit einem beweglichen Bauteil der Vorrichtung verbunden. Es handelt sich um ein im Inneren des Einsatzkörpers 13 anschlag­begrenzt geführt in der Längsmittelachse x-x verlager­bares Kopfstück 19. Dieses ebenfalls im wesentlichen zylindrischer Gestalt, steckt in Spender-Verschlußstellung etwa mit einem Drittel seiner Länge in der zylindrischen Höhlung des Einsatzkörpers 13. Dieser Überlappungsbe­reich ist zur Führung und Anschlagbegrenzung herange­zogen. Der untere Rand des Kopfstückes 19 besitzt dazu eine nach außen gerichtete Führungsrippe 20 und eine auf seiner zylindrischen Mantelfläche, beabstandet zur Führungsrippe 20 angeformte Rastrippe 21, die in Grund­stellung gegen eine flanschnahe Gegenrippe 22 des Einsatz­körpers 13 tritt. Die abstützende Anlage resultiert aus der Rückstellkraft des Faltenbalges 10, welcher mit einer gewissen Vorspannung eingelagert ist. Konkret tritt dort der Ringbund 18 lagegesichert in eine Ringnut 23 des beweglichen Kopfstückes 19 ein. Letzteres und der Einsatzkörper bilden das Pumpengehäuse der Vorrich­tung V.Another ring collar 18 facing away from the piston is connected to a movable component of the device. It is a head piece 19 which can be displaced in the interior of the insert body 13 and is guided in a limited manner in the longitudinal central axis xx. This also essentially cylindrical shape, is in the dispenser closed position about a third of its length in the cylindrical cavity of the insert body 13. This overlap area is for Guidance and limit stop used. For this purpose, the lower edge of the head piece 19 has an outwardly directed guide rib 20 and a locking rib 21 formed on its cylindrical outer surface, spaced apart from the guide rib 20, which in the basic position occurs against a flange-like counter rib 22 of the insert body 13. The supporting system results from the restoring force of the bellows 10, which is embedded with a certain preload. Specifically, the ring collar 18 enters the ring groove 23 of the movable head piece 19 in a position-secured manner. The latter and the insert body form the pump housing of the device V.

Bei einer reinen Kolben/Zylinder-Version der diesbezüg­lichen Pumpvorrichtung würde zur Sicherung der Grund­stellung des Spenders eine Schraubengang-Druckfeder eingesetzt werden.In the case of a pure piston / cylinder version of the pump device in this regard, a helical compression spring would be used to secure the basic position of the dispenser.

Das Kopfstück 19 besitzt eine gut zugängliche Betätigungs­handhabe B. Letztere besteht aus einer einen Teilbereich des zylindrischen Kopfstückes 19 verschließenden Deck­platte 24. Letztere ist randübergreifend stopfenartig in das Kopfstück 19 eingetrieben und überdeckt mit axialem Abstand y oben das freie Ende eines das Herzstück der Spendermechanik bildenden Ausgangsröhrchens 25. Letzteres ist winkelförmig gestaltet. Es besitzt einen in der Längsmittelachse x-x verlaufenden vertikalen Röhrchenabschnitt a und einen im rechten Winkel abgehen­den, radial gerichteten Röhrchenabschnitt b.The head piece 19 has an easily accessible actuation handle B. The latter consists of a cover plate 24 which closes off a portion of the cylindrical head piece 19. The latter is plugged into the head piece 19 in a plug-like manner and covers the free end of an output tube which forms the heart of the dispensing mechanism at the top y 25. The latter is angular. It has a vertical tube section a running in the longitudinal central axis x-x and a radially directed tube section b extending at a right angle.

Das Ausgaberöhrchen 25 ist linear in der Betätigungs­handhabe B geführt. Hierzu dient eine Führungshülse 26 zylindrischer Gestalt. Sie ist dem Kopfstück 19 gleich angeformt und entspringt einer die Ringnut 23 mitformen­den Querwand 27 des Kopfstückes 19.The dispensing tube 25 is guided linearly in the actuation handle B. A guide sleeve 26 of cylindrical shape is used for this purpose. It is molded onto the head piece 19 and arises from a transverse wall 27 of the head piece 19 which forms the annular groove 23.

Betätigungshandhabenseitig endet die konzentrisch zur zylindrischen Wandung des Kopfstückes 19 verlaufende Führungshülse 26 auf Höhe der Unterseite des Röhrchen­abschnitts b. Höhengleich dazu schließt auch eine vom Kopfstück 19 gebildete Fensterkante 28′ eines zur Quer­seite hin offenen Fensters 28 ab, von welcher Fensterkante 28′ das Ausgaberöhrchen 25 anschlagbegrenzt abgestützt ist.On the actuating handle side, the guide sleeve 26, which runs concentrically to the cylindrical wall of the head piece 19, ends at the level of the underside of the tube section b. Equal in height to this also closes a window edge 28 'formed by the head piece 19' of a window 28 open towards the transverse side, from which window edge 28 'the dispensing tube 25 is supported in a stop-limited manner.

Die führende Innenseite der Führungshülse 26 verläuft umlaufend in radialem Abstand z zur Mantelwand des Röhrchenabschnitts a. Der so vorliegende Ringraum 29 ist durch eine Kolbenwand 30 querverschlossen. Bezüg­lich dieser Kolbenwand handelt es sich um eine Ring­lippe mit kolbenseitiger Schrägung, so daß die Steck­montage erleichtert ist. Die durchgehend auf einer Quer­schnittsebene umlaufende Kolbenwand 30 befindet sich in Grundstellung im unteren Drittel des längeren Röhr­chenabschnitts a. Im Bereich des anderen Endes erfolgt die Abstützung über Längsrippen 31, welche auf der Mantelfläche des besagten Röhrchenabschnitts sternförmig angeordnet sind, zumindest in der Anzahl drei. Zur Verbesserung des Gleitvermögens sind die Stirnenden der Längsrippen gefast, d.h. abgeschrägt.The leading inside of the guide sleeve 26 runs circumferentially at a radial distance z to the outer wall of the Tube section a. The annular space 29 thus present is cross-closed by a piston wall 30. With regard to this piston wall, there is an annular lip with a bevel on the piston side, so that the plug-in assembly is facilitated. The piston wall 30 running continuously on a cross-sectional plane is in the basic position in the lower third of the longer tube section a. In the area of the other end, the support is provided via longitudinal ribs 31, which are arranged in a star shape on the lateral surface of said tube section, at least three in number. The end faces of the longitudinal ribs are chamfered, ie beveled, to improve the sliding ability.

In der aus Fig. 1 ersichtlichen Verschlußstellung über­greift die kolbenseitige Eintrittsöffnung 25′ des Aus­gaberöhrchens 25 ein im vorliegenden Falle gehäusefestes Schließventil 32. Es handelt sich um eine röhrchenein­wärts gerichtete stopfenartige Ausdrückung der Querwand 27. Im dargestellten Ausführungsbeispiel befindet sich das so gestaltete Ausgabeventil also an einem beweg­lichen Teil, nämlich an der Betätigungshandhabe B, sprich Kopfstück 19 und die zugehörige Ventilsitzfläche ebenfalls an einem relativ dazu beweglichen Teil, nämlich dem Ausgaberöhrchen 25. Bei einem anderen Pumpensystem be­steht natürlich die Möglichkeit, das Schließventil 32 ortsfest, bspw. an einem Auslegerarm des Gehäuses 1 zu lagern.In the closed position shown in FIG. 1, the piston-side inlet opening 25 'of the dispensing tube 25 overlaps a closing valve 32 which is fixed to the housing in the present case. It is a stopper-like expression of the transverse wall 27 directed towards the inside of the tube movable part, namely on the actuating handle B, that is to say the head piece 19 and the associated valve seat surface also on a part movable relative thereto, namely the dispensing tube 25. Of course, in another pump system it is possible to have the closing valve 32 stationary, for example on an extension arm of the housing 1 to store.

Zum Übertritt des in der Pumpenkammer 9 befindlichen pastösen Gutes in den Kanalquerschnitt des Ausgaberöhr­chens 25 ist die das Schließventil 32 tragende Quer­wand 27 durchbrochen. Die Durchbrechung beginnt am Stopfen­fuß des Schließventils 32 und erstreckt sich in Form mehrerer Radialschlitze 33 in Richtung der Ringnut 23, ohne diese natürlich zu tangieren.In order to pass the pasty material located in the pump chamber 9 into the channel cross section of the dispensing tube 25, the transverse wall 27 carrying the closing valve 32 is broken. The opening begins at the plug base of the closing valve 32 and extends in shape a plurality of radial slots 33 in the direction of the annular groove 23 without naturally affecting it.

Sobald das Ausgaberöhrchen 25 aus seiner Dichtschließ­stellung zum Schließventil 32 getreten ist, ist der Strömungsweg durch das Ausgaberöhrchen 25 hindurch frei. Andererseits besteht aber eine ständig offene Verbindung zwischen der Pumpenkammer 9 und dem kolbenseitigen Ring­raumabschnitt 29′ vor der Kolbenwand 30 des Ausgabe­röhrchens 25. Der größere Längenabschnitt der Radial­schlitze 33 erstreckt sich in einer konischen, in die Pumpenkammer 9 ragende Partie der Querwand 27. Die Ra­dialschlitze 33 lassen zwischen sich einen korbartigen Körper bildende Stege stehen.As soon as the dispensing tube 25 has come out of its tightly closed position to the closing valve 32, the flow path through the dispensing tube 25 is clear. On the other hand, there is a constantly open connection between the pump chamber 9 and the piston-side annular space section 29 'in front of the piston wall 30 of the dispensing tube 25. The larger longitudinal section of the radial slots 33 extends in a conical portion of the transverse wall 27 which projects into the pump chamber 9. The radial slots 33 leave webs forming a basket-like body between them.

Im Boden 12 des Einsatzkörpers 13 befindet sich sodann ein Einlaßventil V 1. Dieses ist als Ventilteller ge­staltet, dessen Ventilsitzfläche vom Stirnrand eines in Richtung der Pumpenkammer 9 auslippenden Kragens 34. Vom Teller des Einlaßventils V 1 gehen leicht ein­wärts versetzte, axiale Führungsstege 35 aus, die über diesen angeformte Anschlagnasen 36 den Ventilhub defi­nieren und den Ventilkörper so im zylindrischen Kragen 34 fesseln.An inlet valve V 1 is then located in the bottom 12 of the insert body 13. This is designed as a valve plate, the valve seat surface of which extends from the end edge of a collar 34 that licks out in the direction of the pump chamber 9. the stop lugs 36 formed over these define the valve lift and thus bind the valve body in the cylindrical collar 34.

Das Einlaßventil V 1 und das Schließventil 32, welches auch als Auslaßventil bezeichnet werden kann, kontrollie­ren den portionsweisen Massedurchsatz.The inlet valve V 1 and the closing valve 32, which can also be referred to as an outlet valve, control the mass flow in portions.

Beim Ausführungsbeispiel gemäß den Fig. 4 und 5 liegt ebenfalls eine Doppelventilanordnung vor. Das Einlaß­ventil V 1 ist dabei in gleicher Weise ausgebildet wie das Einlaßventil V 1 des ersten Ausführungsbeispiels. Es setzt sich jedoch über einen axialen Schaft 37 in das Auslaßventil V 2 fort. Letzteres befindet sich im Inneren des Ausgaberöhrchens 25. In Grundstellung liegt das Auslaßventil V 2 etwa auf Höhe der Kolbenwand 30.In the embodiment according to FIGS. 4 and 5 there is also a double valve arrangement. The inlet valve V 1 is designed in the same way as the inlet valve V 1 of the first embodiment. However, it sits over an axial shaft 37 in the exhaust valve V 2 continues. The latter is located inside the dispensing tube 25. In the basic position, the outlet valve V 2 is located approximately at the level of the piston wall 30.

Das Auslaßventil V 2 besteht aus zwei vom Kopf des Schaf­tes ausgehenden Ventilklappen 37′ gleicher Flächengröße. Bei Durchströmen der Masse falten sich die beiden Ven­tilklappen 37′ praktisch buchseitenartig zusammen (vergl. Fig. 5). Die Ventilklappen nehmen in Dichtstellung eine Y-förmige Gestalt ein, d. h. die Ventilklappen diver­gieren nach oben hin. In dieser Stellung nehmen sie eine randdichte Anlage zur Innenfläche des Ausgaberöhr­chens 25 ein. Die Ventilklappen 37′ können zu den freien Enden hin leicht zugespitzt sein und bestehen aus flexi­blem Material mit genügender Rückstellkraft.The outlet valve V 2 consists of two valve flaps 37 'starting from the head of the shaft and having the same area size. When flowing through the mass, the two valve flaps 37 'fold together practically like a book page (see FIG. 5). The valve flaps assume a Y-shape in the sealing position, i. H. the valve flaps diverge upwards. In this position, they assume an edge-tight contact with the inner surface of the dispensing tube 25. The valve flaps 37 'can be slightly tapered towards the free ends and are made of flexible material with sufficient restoring force.

In der unbetätigten Stellung, also Grundstellung der Spendermechanik ist die Austrittsöffnung Ö hinter ein ortsfestes Verschlußteil 38 gefahren (vergl. Fig. 1 und 4). Bezüglich dieses Verschlußteils 38 handelt es sich um einen vertikalen Wandabschnitt des Kopfstückes 19, und zwar dargestellt, daß die das Verschlußteil 38 formende Wandpartie innenseitig eine ebene Fläche 38′ bildet, die raumparallel zur Stirnfläche 39 des Röhrchenabschnitts b verläuft. Die obere Stirnkante ist zu einer Schneide 38˝ gestaltet.In the unactuated position, that is to say the basic position of the dispenser mechanism, the outlet opening O has moved behind a stationary closure part 38 (cf. FIGS. 1 and 4). Regarding this closure part 38 is a vertical wall section of the head piece 19, and shown that the part of the wall forming the closure part 38 forms a flat surface 38 'on the inside, which runs parallel to the end face 39 of the tube section b. The upper front edge is designed to a cutting edge 38˝.

Der das eigentliche Verschlußteil 38 bildende vertikale Wandabschnitt setzt sich über mindestens eine etwa radial gerichtete Seitenwand 40 in die zylindrische Mantelwand des Kopfstückes 19 fort. Zweckmäßig sind jedoch zwei Seitenwände 40 angeformt, die, auf den Außendurchmesser des Röhrchenabschnitts b abgestimmt, einen vertikalen Führungsschacht 41 schaffen. Der Führungsschaft 41 ist nach unten hin offen gelassen. Dadurch können Pasten­reste nicht zu einer Verkürzung des vertikalen Bewegungs­hubs des Ausgaberöhrchens 25 führen.The vertical wall section forming the actual closure part 38 continues via at least one approximately radially directed side wall 40 into the cylindrical jacket wall of the head piece 19. However, two side walls 40 are expediently formed, which, coordinated with the outer diameter of the tube section b, create a vertical guide shaft 41. The leadership shaft 41 is left open at the bottom. As a result, paste residues cannot lead to a shortening of the vertical movement stroke of the dispensing tube 25.

Der Führungsschacht 41 geht in das Fenster 28 des Kopf­stückes 19 über. In der Betätigungsstellung verläßt der horizontale Röhrchenabschnitt b jedoch den Führungs­schacht 41 nicht, da sich seine Seitenwände 40 über die Oberkante der Schneide 38˝ hinaus noch schräg nach oben ansteigend fortsetzen.The guide shaft 41 merges into the window 28 of the head piece 19. In the actuating position, however, the horizontal tube section b does not leave the guide shaft 41, since its side walls 40 continue to rise obliquely upwards beyond the upper edge of the cutting edge 38˝.

Gemäß Variante Fig. 2 befindet sich im Bereich des Ab­standes y oberhalb des Röhrchenabschnitts b eine weiche Feder 42. Es handelt sich bspw. um eine schräggestellte Blattfeder. Diese ist entweder hahnenkammartig der Ober­seite des Röhrchenabschnitts b angeformt oder aber der korrespondierenden Deckenseite der Deckplatte 24 innen­seitig angespritzt.According to variant FIG. 2, a soft spring 42 is located in the area of the distance y above the tube section b. It is, for example, an inclined leaf spring. This is either molded onto the top of the tube section b in the manner of a cock's comb, or else the inside of the corresponding cover side of the cover plate 24 is injection molded.

Statt pastöser Masse M kann das Gehäuse 1 auch Flüssig­keit aufnehmen, in welchem Falle dann vom Boden 12 des Einsatzkörpers 13 ein nicht dargestelltes Steigrohr ausginge. Zum dadurch erforderlichen Luftausgleich würde der Einsatzkörper 19 eine kleine Durchtrittsöffnung aufweisen, zweckmäßig im Bereich des Ringbundes 11, welcher dabei Ventilfunktion übernehmen könnte. Das Loch läge dann im nicht gefaßten Bereich des besagten Ringbundes.Instead of pasty mass M, the housing 1 can also hold liquid, in which case a riser pipe, not shown, would then emanate from the bottom 12 of the insert body 13. The insert 19 would have a small passage opening for the necessary air balance, expediently in the area of the collar 11, which could take over valve function. The hole would then lie in the area of the said collar which is not contained.

Die Betätigungshandhabe B bildet im Zentrum der Deck­platte 24 einen diese nach oben hin überragenden kleinen Zapfen 43 aus.The actuating handle B forms in the center of the cover plate 24 a small pin 43 which projects upwards therefrom.

Das fertige, gefüllte Produkt besitzt eine die Spender­ mechanik überfangende Schutzkappe 44. Im Bereich der Halspartie 5 weist deren Rand eine Originalitätssicherung 45 auf in Form eines die Rastlippe 16 untergreifenden Ringes. Zwischen Ring und Kappenrand befindet sich eine Sollbruchstelle in Form einer Kerbrinne 46 (Fig. 2). Der Ring besitzt eine nicht näher dargestellte Zuglasche. Die oberseitige Abstützung der Schutzkappe 44 bilden an der Innenwandung des topfförmigen Kappenkörpers ange­formte Längsrippen 47, welche mit ihrer Unterseite auf den ebenen Ringflansch 15 aufsetzen.The finished, filled product has a dispenser protective cap 44 covering the mechanics. In the area of the neck section 5, the edge thereof has a tamper-evident device 45 in the form of a ring which engages under the locking lip 16. Between the ring and the edge of the cap there is a predetermined breaking point in the form of a notch groove 46 (FIG. 2). The ring has a pull tab, not shown. The top-side support of the protective cap 44 form on the inner wall of the cup-shaped cap body formed longitudinal ribs 47, which rest on the flat ring flange 15 with their underside.

Die Funktion ist wie folgt:
Nach Entfernen der Schutzkappe 44 ist die Betätigungshand­habe B zugänglich. Druckausübung in Richtung des Pfei­les P führt bei schon gefüllter Ausgabestrecke zu einer Verringerung des Volumens in der Pumpenkammer 9 zufolge Zusammendrückens des Pumpenbalges 10. Als Reaktion ergibt sich bei genügendem Komprimierungsdruck ein gegenläufiges Hochschnellen des frei verschieblich, geführt gelagerten Ausgaberöhrchens 25, indem die Kolbenwand 30 unter Druck gerät. Durch dieses Hochschießen des Ausgaberöhrchens 25 wird zum einen die Verschlußlage des Ausgabröhrchens aufgehoben, indem seine Austrittöffnung Ö sich aus dem Bereich des Verschlußteils 38 verlagert, und zum anderen das Schließventil 32 geöffnet, da sich der diesbezügliche innere Endabschnitt 25′, also die Eintrittsöffnung des Ausgaberöhrchens davon abhebt. Bei der Abwärtsverlage­rung der Betätigungshandhabe B bzw. des Kopfstückes 19 relatiy zum ortsfesten Einsatzkörper 13 bleibt das Eingangsventil V 1 geschlossen zufolge des Komprimierungs­drucks in der Pumpenkammer 9. Der um den Abstand y nach oben getretene Röhrchenabschnitt b ist dabei in eine völlige Freigabelage getreten, so daß der Strang der pastösen Masse sauber ausgebracht wird. Dies geschieht zufolge des zunehmenden Komprimierungsdruckes und des spontanen, überlagernd stattfindenden Abdrückens des Ausgaberöhrchens 25 in Gegenrichtung auch recht zügig. Wird nun die Betätigungstaste B nach erfolgter Ausbringung wieder losgelassen, bewirkt die Federkraft des Faltenbal­ges die Rückführung in die Verschlußstellung, d. h. das Kopfstück 19 fährt wieder aus. Hieraus ergibt sich ein Unterdruck in der Pumpenkammer 9, welcher Unter­druck zum einen das Eingangsventil V 1 von seiner Ventil­sitzfläche abhebt, so daß aus dem Vorrat pastöse Masse M in die Pumpenkammer 9 gesaugt wird. Um den entsprechen­den Volumenanteil wird dabei der Kolben 6 über die Füll­standssäule nachgezogen. Zum anderen bewirkt das gleiche Vakuum das Einziehen des "schwimmend" gelagerten Ausgabe­röhrchens 25 in die Schließstellung (Fig. 1), also unter Bewirkung des sogenannten Selbstschließeffekts. Einher­gehend setzt das balgseitige Röhrchenende auf das Schließ­ventil 32 auf. Bis dieses geschehen ist, hat sich im Bereich der Austrittöffnung Ö durch den entsprechenden Anschluß an das Vakuum eine Delle eingesaugt. Es er­gibt sich also kein Überstand an pastöser Masse. Das saubere Ende des Röhrchens gleitet in den Führungsschacht 41 ein, wieder vor das Verschlußteil 38 tretend.
The function is as follows:
After removing the protective cap 44, the actuating handle B is accessible. Applying pressure in the direction of arrow P leads to a reduction in the volume in the pump chamber 9 due to the pump bellows 10 being compressed when the discharge path is already filled Pressure device. This shooting up of the dispensing tube 25 firstly removes the closed position of the dispensing tube by moving its outlet opening Ö out of the area of the closing part 38, and secondly opens the closing valve 32, since the relevant inner end section 25 ', i.e. the inlet opening of the dispensing tube stands out from it. When the actuating handle B or the head piece 19 is moved downward relative to the stationary insert body 13, the inlet valve V 1 remains closed due to the compression pressure in the pump chamber 9. The tube section b, which has moved upward by the distance y, has entered a complete release position so that the strand of the pasty mass is applied cleanly. this happens due to the increasing compression pressure and the spontaneous, overlaying pushing of the dispensing tube 25 in the opposite direction, it is also quite rapid. If the actuation button B is released after the application, the spring force of the bellows causes the return to the closed position, ie the head piece 19 extends again. This results in a vacuum in the pump chamber 9, which vacuum lifts the inlet valve V 1 from its valve seat surface, so that paste-like mass M is sucked into the pump chamber 9 from the supply. The piston 6 is pulled over the level column by the corresponding volume fraction. On the other hand, the same vacuum causes the "floating" dispensing tube 25 to be drawn into the closed position (FIG. 1), that is, with the effect of the so-called self-closing effect. At the same time, the bellows-side tube end rests on the closing valve 32. Until this has happened, a dent has been sucked into the area of the outlet opening Ö through the corresponding connection to the vacuum. There is therefore no excess pasty mass. The clean end of the tube slides into the guide shaft 41, again in front of the closure part 38.

Das Einlaßventil V 1 braucht dabei nicht einmal in seine Schließstellung zu treten, was unter Berücksichtigung der Reibungskräfte und der pastösen Masse denkbar ist, so daß sogar ein ständiger Feuchteanschluß des in der Pumpenkammer 9 eingeschlossenen Anteils zur im Gehäuse 1 befindlichen Restmasse M gegeben ist.The inlet valve V 1 does not even have to step into its closed position, which is conceivable taking into account the frictional forces and the pasty mass, so that even a constant moisture connection of the portion enclosed in the pump chamber 9 to the residual mass M in the housing 1 is given.

Der Kolben 6 besitzt eine Struktur, die ein möglichst restfreies Ausgeben der pastösen Masse gewährleistet.The piston 6 has a structure which ensures that the pasty mass is dispensed as completely as possible.

Die Funktion des Spenders gemäß dem zweiten Ausführungs­beispiel (Fig. 4 und 5) ist im wesentlichen gleich, und zwar sowohl im Hinblick auf die selbstschließende Wirkung und die Ausbringung, nur daß bei Ausgabe durch die schöpfwerkartige Funktion des Auslaßventils V 2 ein Teilabschnitt des Stranges relativ zur Röhrchen­bewegung ausgeschoben wird, da dieses Auslaßventil V2 über den Schaft 37 mit dem in seine Schließstellung getretenen Einlaßventil V1 verbunden ist. Bei weiterer Abwährtsverlagerung des Kopfstückes 19 kommt zu diesem aktiv ausgeschobenen Strangabschnitt ergänzend auch noch ein solcher, der durch den Komprimierungsdruck, also entsprechende Verdrängungskräfte, bewirkt wird. Dabei legen sich dann die Ventilklappen 37′ gegeneinander (vergl. Fig. 5), so daß das Auslaßventil von dem Masse­strom umspült wird. Ist der Ausgabehub durchlaufen und setzt zufolge der Rückstellwirkung des Balgmateriales Unterdruck ein, lutscht sich hier etwaiger Strang-Über­stand in die Austrittöffnung Ö sauber ein. Das Ausgabe­röhrchen 25 tritt, auch gegebenenfalls noch unterstützt durch sein Eigengewicht, wieder in die Verschlußstellung, bewirkt vor allem durch die oben erläuterte Wirkung der Kolbenwand 30. Die Anlage der Ventilklappen 37′ an der Innenwandung des Ausgaberöhrchens 25 bringt auch eine gewisse erhöhte Reibung mit sich, so daß hierüber das über den Schaft 37 angebundene Einlaßventil V1 so­gar aktiv geschlossen wird.The function of the dispenser according to the second embodiment (Fig. 4 and 5) is essentially the same, both in terms of the self-closing effect and the output, only that when output by the scoop-like function of the exhaust valve V 2, a portion of the strand relative is pushed out for tube movement, since this outlet valve V2 is connected via the shaft 37 to the inlet valve V1 which has entered its closed position. If the head piece 19 is shifted further downward, this strand section which is actively pushed out is supplemented by one which is caused by the compression pressure, that is to say corresponding displacement forces. The valve flaps 37 'then lie against each other (see FIG. 5), so that the exhaust valve is washed by the mass flow. If the dispensing stroke has been completed and, due to the restoring effect of the bellows material, negative pressure is applied, any strand protrusion sucks cleanly into the outlet opening Ö. The dispensing tube 25 occurs, possibly also supported by its own weight, again in the closed position, caused primarily by the above-described effect of the piston wall 30. The contact of the valve flaps 37 'on the inner wall of the dispensing tube 25 also brings with it a certain increased friction , so that the inlet valve V1 connected via the shaft 37 is even actively closed.

Aus Gründen der deutlicheren Wiedergabe ist die pastö­se Masse im Bereich der Spendermechanik nicht darge­stellt.For reasons of clearer reproduction, the pasty mass in the area of the dispenser mechanism is not shown.

Während bei den vorbeschriebenen Ausführungsbeispielen das die Betätigungshandhabe B bildende Kopfstück 19 und das Röhrchen 25 bei der Auf- und Abwärtsbewegung des Kopfstücks 19 Relativbewegungen ausführen, sind bei den nachfolgenden Ausführungsbeispielen die Betäti­gungshandhabe B und das Röhrchen 25 starr miteinander verbunden, bzw. einstückig zueinander.While in the above-described exemplary embodiments the head piece 19 forming the actuating handle B. and the tube 25 perform relative movements during the upward and downward movement of the head piece 19, in the following exemplary embodiments the actuating handle B and the tube 25 are rigidly connected to one another or in one piece to one another.

Nach den Fig. 6 und 7 ist das im zylindrischen Einsatz­körper 13 geführte Kopfstück 19 über eine innere radi­ale Schulter mit dem Röhrchen 25 verbunden. Zwischen den Ringnuten 14, 23 ist der Faltenbalg 10 gehalten. In das zylindrische Kopfstück 19 ist die Betätigungs­handhabe B1 aufgesetzt, die mittig eine Bohrung aufweist, durch die das Röhrchen 25 geführt ist. Die Pumpenkammer 9 wird begrenzt durch den Balg 10, die vorerwähnte innere radiale Schulter und den Boden 12. Die Arbeitsweise entspricht der Ausführungsform nach den Fig. 4 und 5 mit Ausnahme, daß keine Relativbewegung zwischen dem Röhrchen 25 und dem Kopfstück 19 stattfindet. Bei den Ausführungsformen nach den Fig. 8, 9, 12 und 13 ist der Faltenbalg 10 in Wegfall gekommen. Die Pumpenkammer 9 wird jeweils begrenzt durch den Boden 12 und eine zylindrische Wandung 125 des Einatzkörpers 13, der ein­stückig zur Wandung 1 sein kann, sowie dem als Kolben ausgebildeten Röhrchen 25, das in der zylindrischen Wandung 125 geführt ist.6 and 7, the head piece 19 guided in the cylindrical insert body 13 is connected to the tube 25 via an inner radial shoulder. The bellows 10 is held between the annular grooves 14, 23. In the cylindrical head piece 19, the actuation handle B1 is placed, which has a hole in the center through which the tube 25 is guided. The pump chamber 9 is delimited by the bellows 10, the aforementioned inner radial shoulder and the bottom 12. The method of operation corresponds to the embodiment according to FIGS. 4 and 5 with the exception that there is no relative movement between the tube 25 and the head piece 19. In the embodiments according to FIGS. 8, 9, 12 and 13, the bellows 10 has been eliminated. The pump chamber 9 is in each case delimited by the base 12 and a cylindrical wall 125 of the insert body 13, which can be in one piece with the wall 1, and the tube 25 designed as a piston, which is guided in the cylindrical wall 125.

Bei dem Ausführungsbeispiel gemäß Fig. 8 ist der Spender im Kopfbereich mit zwei Ringkammern 123 und 124 ausge­bildet. Die Ringkammern sind gegensinnig eingezogen, einstückig mit dem Spendergehäuse 1 gestaltet. Die äußere Ringkammer 123 ist nach unten, zum Spenderinneren hin geöffnet und die innere Ringkammer 124 nach oben. Die innere Wandung 125 der inneren Ringkammer 124 bildet gleichzeitig die Wandung der Pumpkammer 107 und der Pumpenkammer 6 bei dem Ausführungsbeispiel gem. Fig. 8. Eine Feder 126 ist in der inneren Ringkammer 124 angeordnet. Dadurch, daß die Pumpkammer 107 bei diesem Ausführungsbeispiel durch den äußeren zylindrischen Raum der Wandung 125 der inneren Ringkammer 124 gebildet wird, ist die Feder 126 in einem nicht von Masse durch­strömten Raum angeordnet. Die gleichfalls zylindrisch ausgebildete Wandung 127 zwischen der äußeren und inne­ren Ringkammer geht über die Anbindung 128 in das Spender­gehäuse 1 über.In the exemplary embodiment according to FIG. 8, the dispenser is formed in the head region with two annular chambers 123 and 124. The annular chambers are drawn in in opposite directions, designed in one piece with the dispenser housing 1. The outer annular chamber 123 is open at the bottom, towards the inside of the dispenser, and the inner annular chamber 124 is at the top. The inner wall 125 of the inner annular chamber 124 simultaneously forms the wall of the pump chamber 107 and Pump chamber 6 according to the embodiment. Fig. 8. A spring 126 is disposed in the inner annulus 124. Because the pump chamber 107 is formed in this exemplary embodiment by the outer cylindrical space of the wall 125 of the inner annular chamber 124, the spring 126 is arranged in a space through which no mass flows. The likewise cylindrical wall 127 between the outer and inner annular chamber merges into the dispenser housing 1 via the connection 128.

Fig. 9 zeigt den Spenderkopf der Ausführungsform gemäß Fig. 8 in niedergedrückter Stellung. Bezüglich des Ein­laßventiles V1 und des Auslaßventiles V2 ergibt sich im übrigen die gleiche Charakteristik wie zuvor im Hin­blick auf die Fig. 5 bis 7 beschrieben.FIG. 9 shows the dispenser head of the embodiment according to FIG. 8 in the depressed position. With regard to the inlet valve V1 and the outlet valve V2, the same characteristic results as described above with regard to FIGS. 5 to 7.

An das Ausgaberöhrchen 25, das im übrigen bei dieser Version in seinem oberen Bereich abgewinkelt gestaltet ist, mit einer seitlichen Austrittsöffnung Ö, ist im Bereich der Einlaßöffnung 130 ein Kolben 131 der Pumpen­kammer 9 unmittelbar angeordnet.A piston 131 of the pump chamber 9 is arranged directly in the area of the inlet opening 130 on the dispensing tube 25, which in the rest of this version is angled in its upper region with a lateral outlet opening Ö.

Die Feder 126 stützt sich im unteren Bereich auf eine Anbindung zwischen den zylindrischen Wandungen 125 und 127 ab. Im oberen Bereich sind in die durch das Ausga­beröhrchen 25 und die äußere zylindrische Wandung 132 der Betätigungshandhabe B2 gebildete Ringkammer verti­kal verlaufende Streben 133 eingezogen, die einen Anschlag für die Feder 126 bilden.The spring 126 is supported in the lower region on a connection between the cylindrical walls 125 and 127. In the upper region, vertically extending struts 133 are drawn into the annular chamber formed by the dispensing tube 25 and the outer cylindrical wall 132 of the actuating handle B2, which struts form a stop for the spring 126.

Damit die Öffnung Ö bei Nichtgebrauch verschlossen ist, ist an der Anbindung 128 zwei nach oben gerichtete Seitenwände 40 angeformt, die über das Verschlußteil 38 miteinander verbunden sind und gegen die bei Nichtge­brauch die Öffnung Ö zur Anlage kommt. Unterhalb des Verschlußteils ist das Fenster 28 vorhanden, so daß bei Betätigung der Betätigungshandhabe B2 das Material aus dem Röhrchen 25 auszutreten vermag.So that the opening Ö is closed when not in use, two upwardly directed side walls 40 are formed on the connection 128, which are connected to the closure part 38 are connected to each other and against which the opening Ö comes into contact when not in use. The window 28 is provided beneath the closure part, so that the material can escape from the tube 25 when the actuating handle B2 is actuated.

Das Ausführungsbeispiel gemäß den Fig. 10 und 11 be­trifft einen Spender für Flüssigkeiten. Unterhalb des Einlaßventiles V1 ist in einem Stutzen 124 ein Ansaug­schlauch 135 befestigt. Überdies besitzt der Spender gemäß Fig. 10 eine schwenkbare Tülle 136, die an dem Ausgaberöhrchen 25 verschwenkbar angebracht ist. In der Darstellung gemäß Fig. 11 befindet sich die Tülle 136 in der ausgeschwenkten Stellung.The exemplary embodiment according to FIGS. 10 and 11 relates to a dispenser for liquids. An intake hose 135 is fastened in a nozzle 124 below the inlet valve V1. Furthermore, the dispenser according to FIG. 10 has a pivotable spout 136 which is pivotably attached to the dispensing tube 25. 11, the spout 136 is in the pivoted-out position.

Die Schwenktülle 136 ist von Bedeutung für die Montage des Spenderkopfes. Bei niedergedrückter Tülle 136, wie in Fig. 10, kann der Pumpenkopf praktisch nicht kompri­miert werden.The swivel spout 136 is important for the assembly of the dispenser head. When the nozzle 136 is depressed, as in FIG. 10, the pump head can practically not be compressed.

Das Ausführungsbeispiel gemäß Fig. 12 zeigt das obere Teil eines Spenders, im übrigen gemäß Fig. 9 in nieder­gedrückter Stellung. Bei dieser Ausführungsform ist ein alternatives Auslaßventil V2 verwirklicht. Es be­steht aus einer bei 240 in dem Ausgabeföhrchen 25 an­scharnierten Ventilklappe. Das Auslaßventil V2 und das Einlaßventil V1 sind bei dieser Version also nicht mehr miteinander verbunden. Sie können unabhängig voneinander sich bewegen. Von Besonderheit ist, daß das Auslaßventil V2 in dem kolbenartig bewegbaren Auslassröhrchen 25 angebracht ist, also - relativ zu dem Ausgaberöhrchen 25 ortsfest - die Bewegung des Ausgaberöhrchens 25 mit­vollzieht.The exemplary embodiment according to FIG. 12 shows the upper part of a dispenser, otherwise according to FIG. 9 in the depressed position. In this embodiment, an alternative exhaust valve V2 is implemented. It consists of a valve flap hinged to 240 in the dispensing tube 25. The outlet valve V2 and the inlet valve V1 are therefore no longer connected to one another in this version. You can move independently of each other. It is special that the outlet valve V2 is mounted in the piston-like movable outlet tube 25, that is to say - in a stationary manner relative to the dispensing tube 25 - the movement of the dispensing tube 25 is carried out.

Bei dem Ausführungsbeispiel gemäß Fig. 13 besteht der Spender aus einem unteren zylindrischen Gehäuse 1 und einem Spenderkopf, der insgesamt mit V bezeichnet ist. Bei der Darstellung ist der Spenderkopf V von einer Kappe 44 überfangen.In the exemplary embodiment according to FIG. 13, the dispenser consists of a lower cylindrical housing 1 and a dispenser head, which is designated overall by V. In the illustration, the dispenser head V is covered by a cap 44.

Das zylindrische Spendergehäuse 1 ist mit dem Spenderkopf V schraubverbindbar. Hierzu besitzt das Spendergehäuse 1 in seinem oberen Endbereich eine zylindrische Erwei­terung 141, die mit einem Innengewinde ausgebildet ist. In diese Erweiterung 141 ist ein Anschlußteil 142 einge­schraubt. Das Anschlußteil 142 besitzt einen kleineren inneren lichten Durchmesser als das zylindrische Spender­gehäuse 1. Das Anschlußteil 142 ist mit einem Außenge­winde zum Einschrauben in dem Spendergehäuse 1 sowie mit einem Innengewinde zur Schraubverbindung mit dem Spenderkopf V ausgebildet. Desweiteren besitzt das An­schlußteil 142 innenseitig eine umlaufende Nut 143. Der Spenderkopf V ist in seinem unteren Bereich ent­sprechend mit einem Außengewinde 144 ausgebildet, wel­ches stegartig bei 145 ausläuft, zum Eingriff in die Nut 143. Aufgrund der im Querschnitt etwa dreieckförmi­gen Gestaltung des Abschlußbodens des Spenderkopfes V bei 146 ergibt sich eine zweifache Dichtkante. Einmal liegt der Fortsatz 145 an der Innenwand 147 der Nut 143 an, zum anderen liegt der Fortsatz dieser Innen­wand der Nut 143 in der bodenseitigen Kehle des Spender­kopfes V an.The cylindrical dispenser housing 1 can be screw-connected to the dispenser head V. For this purpose, the dispenser housing 1 has in its upper end region a cylindrical extension 141 which is designed with an internal thread. A connector 142 is screwed into this extension 141. The connecting part 142 has a smaller inner clear diameter than the cylindrical dispenser housing 1. The connecting part 142 is formed with an external thread for screwing into the dispenser housing 1 and with an internal thread for screw connection with the dispenser head V. Furthermore, the connecting part 142 has a circumferential groove 143 on the inside. The dispenser head V is correspondingly formed in its lower region with an external thread 144, which terminates at 145 in a web-like manner, for engaging in the groove 143. Due to the approximately triangular cross-section of the bottom of the dispenser head V at 146 results in a double sealing edge. On the one hand, the extension 145 bears against the inner wall 147 of the groove 143, and on the other hand the extension of this inner wall of the groove 143 lies in the bottom-side throat of the dispenser head V.

Fig. 14 stellt ein Austauschteil für einen Spender ge­mäß Fig. 13 dar. Es besteht übereinstimmend zu dem Spender gemäß Fig. 13. aus einem Spendergehäuse 1, wel­cher jedoch astatt durch den Spenderkopf V durch ein Verschlußteil 148 verschlossen ist. Das Verschlußteil 148 ist im übrigen bodenseitig übereinstimmend mit der beschriebenen Ausführung des Spenderkopfes 14 gemäß Fig. 13 ausgebildet. Das Verschlußteil 148 wie auch der Spenderkopf V weisen oberhalb des Verschlußbereiches eine äußere Rändelung 149 auf. Das Verschlußteil 148 ist übrigens oben geöffnet ausgebildet.FIG. 14 shows a replacement part for a dispenser according to FIG. 13. Consistent with the dispenser according to FIG. 13, it consists of a dispenser housing 1 which, however, is closed by a closure part 148 instead of by the dispenser head V. The closure part 148 is otherwise formed on the bottom side in accordance with the described embodiment of the dispenser head 14 according to FIG. 13. The closure part 148 as well as the dispenser head V have an external knurling 149 above the closure area. The closure part 148 is, incidentally, open at the top.

Beim Gebrauch des Spenders wird so vorgegangen, daß ein Spender gemäß Fig. 13 benutzt wird. Nach der üb­lichen Benutzungszeit wird auf eine Betätigung der Aus­gabetaste hin keine Paste mehr aus dem Ausgaberöhrchen 25 austreten. Der Benutzer kann sodann das zylindrische Spendergehäuse 1 abschrauben, wobei sich der Kolben 6 sodann oben unmittelbar unterhalb des Anschlußteils 142 befindet. Ein Nachkaufteil gem. Fig. 14 kann sodann an den Spenderkopf V angeschraubt werden, nachdem die Verschlußkappe 148 entfernt worden ist. Alternativ dazu kann in dem geleerten Spendergehäuse 1 der Kolben 6 niedergedrückt werden und mittels einer Nachfüllpackung oder dergleichen das Spendergehäuse 1 wieder mit pastöser Masse gefüllt werden und sodann das ursprüngliche Spen­dergehäuse 1 wieder an den Spenderkopf V angeschraubt werden. In jedem Fall wird aber eine Wiederverwendung des Spenderkopfes V ermöglicht, was einen entsprechenden Kostenvorteil für den Verbraucher mit sich bringt.When using the dispenser, the procedure is such that a dispenser according to FIG. 13 is used. After the usual time of use, no more paste will emerge from the dispensing tube 25 upon actuation of the dispensing button. The user can then unscrew the cylindrical dispenser housing 1, the piston 6 then being located directly below the connecting part 142 at the top. A replacement part according to Fig. 14 can then be screwed to the dispenser head V after the cap 148 has been removed. Alternatively, the piston 6 can be depressed in the emptied dispenser housing 1 and the dispenser housing 1 can be filled again with pasty mass by means of a refill or the like, and then the original dispenser housing 1 can be screwed back onto the dispenser head V. In any case, a reuse of the dispenser head V is made possible, which brings a corresponding cost advantage for the consumer.
