Abstract

A dispenser, in particular for pasty substances, has a replaceable reservoir (2) that may be emptied by twisting. The advantage of the invention is that it is easy and economic to produce. In addition, it allows the reservoir to be emptied to a very large extent.

Description

Die Erfindung betrifft einen Spender für insbesondere pastöse Substanzen mit einem auswechselbaren Vorratsbehälter, wobei der Vorratsbehälter vorzugsweise als Vorratsbeutel sackartig ausgebildet ist mit einer dünnen, faltbaren Wandung, weiter ein Mündungsende und ein Bodenende aufweist, wobei das Bodenende eine Verstärkung besitzt.The invention relates to a dispenser for pasty substances in particular with an exchangeable storage container, the storage container preferably being designed as a storage bag in a sack-like manner with a thin, foldable wall, furthermore having a mouth end and a bottom end, the bottom end having a reinforcement.

Ein Spender ist beispielsweise aus der EP-A2 219 750 bekannt. Hier wird ein Vorratsbeutel durch eine axial erfolgende Druckbetätigung in dem Spender entleert. Ein solcher Spender wird hinsichtlich seiner Entleerungsmechanik noch als relativ aufwendig empfunden. Außerdem hat sich herausgestellt, daß die Vorratsbeutel bei Druckentleerung nicht oder nur mit großem Aufwand zu einer nahezu vollständigen Entleerung zu bringen sind.A donor is known for example from EP-A2 219 750. Here, a storage bag is emptied in the dispenser by an axial pressure actuation. Such a dispenser is still perceived as relatively complex in terms of its emptying mechanism. In addition, it has been found that the storage bags cannot be brought to almost complete emptying when the pressure is emptied, or only with great effort.

In GB-A-495 856 ist ein verdrehbarer Beutel in einem zweiteiligen Gehäuse untergebracht. Dieser Beutel besitzt an seinem Bodenende ein flügelartiges Drehelement, das in einem Schlitz eines Gleitstückes formschlüssig gehalten ist. Der Spender nach US-A-2 203 313 verwendet einen Vorratsbehälter, dessen Bodenende von einer girlandenartigen Bodenplatte gehalten wird.In GB-A-495 856 a rotatable bag is housed in a two-part housing. This bag has a wing-like rotating element at its bottom end, which is held in a form-fitting manner in a slot of a sliding piece. The dispenser according to US-A-2 203 313 uses a storage container, the bottom end of which is held by a garland-like base plate.

Der Erfindung liegt die Aufgabe zugrunde, einen Spender für insbesondere pastöse Substanzen anzugeben, der bei einfach ausgebildetem Vorratsbeutel eine konstruktiv wenig aufwendige Entleerung des Vorratsbeutels ermöglicht. Auch soll weiter möglichst eine sehr weitgehende Entleerung des Vorratsbeutels möglich sein.The invention is based on the object of specifying a dispenser for pasty substances in particular which, with a simply designed storage bag, enables the storage bag to be emptied with little construction. Furthermore, a very extensive emptying of the storage bag should also be possible.

Die Aufgabe wird mit den Merkmalen der Patentansprüche gelöst.The object is achieved with the features of the claims.

In Ausführungsbeispielen wird dargestellt, daß in dem Spender ein Halterungsteil ausgebildet ist, das um eine durch das Mündungsende und das Bodenende gehende Längsachse des Vorratsbehälters bzw. Vorratsbeutels drehbar ist und daß das Halterungsteil mit der Verstärkung des Bodenendes des Vorratsbeutels zur Verdrillung des Vorratsbeutels zusammenwirkt, wobei der Vorratsbeutel im Bereich des Mündungsendes drehfest in dem Spender gehaltert ist. Erfindungsgemäß ist ein Spender mit einem Vorratsbeutel angegeben, der durch von unten nach oben sich fortsetzende Verdrillung den Inhalt, insbesondere eine pastöse Substanz wie Zahnpasta, Mayonnaise, Ketchup oder dgl., aber auch feste Substanzen wie ein Deo-Stick aus dem Mündungsende des Vorratsbeutels austreibt, In Ausgestaltung ist vorgesehen, daß das Bodenende des Vorratsbeutels formschlüssig in dem Halterungsteil aufgenommen ist. Der einfache Formschluß, der beispielsweise ein Einstecken von oben ermöglicht, ist nur erforderlich hinsichtlich einer Verdrillung des Bodenendes relativ zu dem Mündungsende des Vorratsbeutels. Hieran angepaßt kann der Formschluß beliebig gestaltet sein. Darüber hinaus ist bevorzugt vorgesehen, daß das Bodenende des Vorratsbeutels in dem Halterungsteil des Spendergehäuses axial bewegbar ist. Bei zunehmender Verdrillung verkürzt sich materialabhängig i.a. die Länge des Vorratsbeutels. Dadurch, daß das Bodenende in dem Halterungsteil axial bewegbar ist, geht der Formschluß mit dem Halterungsteil nicht verloren, dem Vorratsbeutel ist es aber ermöglicht, sich axial zu verkürzen. Eine geeignete Ausgestaltung des Bodenendes des Voratsbeutels wird beispielsweise darin gesehen, daß das Bodenende in Form eines Mehrkantstabes ausgebildet ist. Es bietet sich beispielsweise ein Vierkant- oder ein Sechskantprofil hierfür an. Der Stab kann massiv oder auch - bevorzugt -, hinsichtlich Gewichtsreduzierung und Materialersparnis, hohl ausgebildet sein. Das Halterungsteil des Spenders ist in Anpassung an das Bodenende des Vorratsbeutels entsprechend mit einem Innenmehrkant ausgebildet, etwa in einer Ausgestaltung, wie sie von Mehrkantschraubenschlüsseln bekannt ist. Das Mündungsende des Vorratsbeutels ist weiter bevorzugt mit einer Mündungskappe versehen, die mit - äußeren - Formschlußmitteln ausgebildet ist, welche Formschlußmittel eine drehfeste Halterung in dem Spendergehäuse ermöglichen. Alternativ oder zusätzlich kann eine kraftschlüssige Verbindung vorliegen. So kann eine Verdrillung des Bodenendes relativ zu dem Mündungsende des Vorratsbeutels durchgeführt werden, ohne ein Mitdrehen des Mündungsendes. Hinsichtlich der Ausgestaltung des Vorratsbehälters ist darüber hinaus bevorzugt, daß der Vorratsbehälter im wesentlichen aus einer beispielsweise zylinderförmigen extrudierten Kunststoffolie besteht. Hier werden sehr dünne Kunststoffolien bevorzugt. Es ist aber auch möglich, mehrschichtige Kunststoffolien zu verwenden. Alternativ kann der Vorratsbehälter aus mehreren Kunststoffolienteilen bestehen, die vorzugsweise miteinander verschweißt sind. Weiterhin ist bevorzugt, daß das Bodenende des Vorratsbehälters an die Kunststoffolie angespritzt ist. Im einzelnen wird hierzu auf die deutsche Patentanmeldung P 43 21 275.1 verwiesen, deren Offenbarungsinhalt hiermit vollinhaltlich in vorliegende Anmeldung mit aufgenommen wird. Es ist weiterhin auch möglich, die Mündungskappe durch Anspritzen mit der extrudierten Kunststoffolie zu verbinden, z.B. in Form eines Klappverschlusses. Im einzelnen wird hierzu auch auf die vorerwähnte Patentanmeldung verwiesen. Darüber hinaus ist schließlich noch eine bevorzugte Ausgestaltung darin zu sehen, daß der Vorratsbehälter im Bereich des Bodenendes eine Verjüngung aufweist, zur Festlegung eines Ausgangsquerschnittes beim Verdrillen. Der - mit Masse gefüllte - kleinste Querschnitt des Vorratsbehälters setzt bei einer Verdrillung den geringsten Widerstand entgegen und wird daher beginnen sich zusammenzuziehen, wenn ein entsprechendes Drehmoment auf den Vorratsbehälter aufgebracht wird.In exemplary embodiments it is shown that a holding part is formed in the dispenser, which can be rotated about a longitudinal axis of the storage container or storage bag passing through the mouth end and the bottom end, and that the holding part interacts with the reinforcement of the bottom end of the storage bag for twisting the storage bag, whereby the storage bag in the area of the mouth end is rotatably held in the dispenser. According to the invention, a dispenser is specified with a storage bag which, by twisting from bottom to top, expels the contents, in particular a pasty substance such as toothpaste, mayonnaise, ketchup or the like, but also solid substances such as a deodorant stick from the mouth end of the storage bag In an embodiment it is provided that the bottom end of the storage bag is positively received in the holding part. The simple positive connection, which for example allows insertion from above, is only necessary with regard to a twisting of the bottom end relative to the mouth end of the storage bag. Adapted to this, the form fit can be designed as desired. In addition, it is preferably provided that the bottom end of the storage bag is axially movable in the holding part of the dispenser housing. With increasing twisting, the length of the storage bag generally shortens depending on the material. Because the bottom end can be moved axially in the holding part, the positive connection with the holding part is not lost, but the storage bag is made possible to shorten axially. A suitable design of the bottom end of the storage bag is seen, for example, in that the bottom end is designed in the form of a polygonal rod. For example, a square or a hexagonal profile is suitable. The rod can be solid or - preferably - hollow in terms of weight reduction and material savings. The holder part of the dispenser is designed to match the bottom end of the storage bag with an internal polygon, for example in a configuration as is known from polygonal wrenches. The mouth end of the storage bag is further preferably provided with a mouth cap which is formed with - outer - form-locking means, which form-locking means enable a rotationally fixed holder in the dispenser housing. Alternatively or additionally, there can be a non-positive connection. In this way, the bottom end can be twisted relative to the mouth end of the storage bag without turning the muzzle end. With regard to the design of the storage container, it is also preferred that the storage container essentially consists of, for example, a cylindrical extruded plastic film. Very thin plastic films are preferred here. However, it is also possible to use multilayer plastic films. Alternatively, the storage container can consist of several plastic film parts, which are preferably welded together. It is further preferred that the bottom end of the storage container is molded onto the plastic film. In particular, reference is made to the German patent application P 43 21 275.1, the disclosure content of which is hereby incorporated in full in the present application. It is furthermore also possible to connect the mouth cap to the extruded plastic film by injection molding, for example in the form of a hinged closure. In particular, reference is also made to the aforementioned patent application. In addition, a preferred embodiment is finally to be seen in the fact that the storage container has a taper in the region of the bottom end, for fixing an initial cross section when twisting. The smallest cross-section of the storage container - filled with mass - provides the least resistance when twisted and will therefore begin to contract when a corresponding torque is applied to the storage container.

Fig. 5 - rechteckig ausgebildet.A dispenser 1 is shown and described first with reference to FIG. 1, for example for dispensing a pasty substance such as toothpaste. The dispenser 1 has - now with reference to FIG. 3 - a storage bag 2 which is interchangeably received in the dispenser housing 3. The storage bag is designed in a sack-like manner with a thin, foldable wall 2a. Furthermore, the storage bag 2 has a mouth end 4 and a bottom end 5. The bottom end 5 is in cross section - cf. Fig. 5 - rectangular.

Im weiteren besteht das Bodenende 5 aus einem Stababschnitt 6 und einem Übergangsbereich 7. Der Übergangsbereich 7 stellt eine Verbindung mit der Folien-Wandung 2a des Vorratsbeutels dar. Wie aus der Darstellung ersichtlich, ist der Übergangsbereich 7 taillenartig verjüngt gegenüber einem mittleren Querschnitt - beispielsweise im Bereich der Linie IV-IV in Fig. 3 - des Vorratsbeutels.Furthermore, the bottom end 5 consists of a rod section 6 and a transition region 7. The transition region 7 represents a connection to the film wall 2a of the storage bag. As can be seen from the illustration, the transition region 7 is tapered like a waist compared to a central cross section - for example in the Area of line IV-IV in Fig. 3 - the storage bag.

Der Stababschnitt 6 ist in einem Halterungsteil 8 des Spenders 1 aufgenommen. Das Halterungsteil 8 ist quer zu einer durch das Mündungsende 4 und das Bodenende 5 gehenden Längsachse a des Vorratsbeutels drehbar. Durch die formschlüssige Aufnahme des Stabsbschnittes 6 in dem Halterungsteil 8 wird bei einer Verdrehung des Halterungsteils 8 eine Verdrillung des Vorratsbeutels erreicht, wie dies in Fig. 6 angedeutet ist.The rod section 6 is received in a holding part 8 of the dispenser 1. The holding part 8 is rotatable transversely to a longitudinal axis a of the storage bag passing through the mouth end 4 and the bottom end 5. Due to the positive reception of the rod section 6 in the holding part 8, the storage bag is twisted when the holding part 8 is rotated, as is indicated in FIG. 6.

Mit zunehmender Verdrillung des Vorratsbeutels wandert das Bodenende 5 und insbesondere der Stababschnitt 6 nach oben, wie dies gleichfalls in Fig. 6 angedeutet ist. Die nach oben hinterschneidungsfreie Öffnung 9 des Halterungsteils 8 läßt diese Axialbewegung zu.With increasing twisting of the storage bag, the bottom end 5, and in particular the rod section 6, moves upward, as is also indicated in FIG. 6. The upward undercut-free opening 9 of the holding part 8 allows this axial movement.

Das Mündungsende 4 weist äußere Rastnocken 10 auf, die in Aussparungen 22 (vgl. 4) in der Spenderwandung 3 eingreifen. sie hindern das Mündungsende 4 an einer Drehbewegung relativ zu dem Spendergehäuse 3. Bei einer Verdrehung des Halterungsteils 8 des Spenders 1 wird somit die gewünschte Verdrillung des Vorratsbehälters erreicht.The mouth end 4 has outer locking cams 10 which engage in recesses 22 (see FIG. 4) in the dispenser wall 3. they prevent the mouth end 4 from rotating relative to the dispenser housing 3. When the holder part 8 of the dispenser 1 is rotated, the desired twisting of the storage container is thus achieved.

Im einzelnen besteht das Mündung sende 4 aus einem konischen Abschnitt 11, der einstückig an einen zylindrischen Abschnitt 12 angeformt ist. Der zylindrische Abschnitt 12 ist mit der extrudierten Kunststoffolie 2a verbunden. Mündungsseitig schließt sich an den konischen Abschnitt 11 eine Ausgabeöffnung 13 an.Specifically, the mouth end 4 consists of a conical section 11 which is integral with a cylindrical section 12 is molded. The cylindrical section 12 is connected to the extruded plastic film 2a. On the mouth side, an outlet opening 13 adjoins the conical section 11.

Das Halterungsteil 8 ist drehfest (beispielsweise durch Klebung) mit einer im Querschnitt topfförmig ausgebildeten Handhabe 14 verbunden, die über einen Ratschenmechanismus mit der Spenderwand 3 zusammenwirkt.The holding part 8 is connected in a rotationally fixed manner (for example by gluing) to a handle 14 which is cup-shaped in cross section and which interacts with the dispenser wall 3 via a ratchet mechanism.

Der Ratschenmechanismus ist im einzelnen in den Figuren 5 und 6 dargestellt. In der Handhabe 14 sind zwei Federfinger 15 ausgeformt, die in axial am Spender orientierte Ausnehmungen 16 eingreifen. Bei einer Verdrehung der Handhabe 14 überlaufen die Federfinger 15 aufgrund einer Schräge 17 Nocken 18 (vgl. Drehung entgegen Pfeilrichtung). Bei einer Drehung in Pfeilrichtung tritt entsprechend eine Sperrung auf und die gewünschte Entleerung des Vorratsbeutels 2 kann erreicht werden.The ratchet mechanism is shown in detail in FIGS. 5 and 6. Two spring fingers 15 are formed in the handle 14, which engage in recesses 16 oriented axially on the dispenser. When the handle 14 is rotated, the spring fingers 15 overlap due to a bevel 17 cams 18 (cf. rotation against the direction of the arrow). With a rotation in the direction of the arrow, a blockage occurs accordingly and the desired emptying of the storage bag 2 can be achieved.

Es ist noch ersichtlich, daß die Handhabe 14 außen gerändelt ist, um eine bessere Handhabung zu ermöglichen. Mittels eines umlaufenden Vorsprunges 19 ist die Handhabe 14 darüber hinaus axial in der Spenderwandung 3 gesichert.It can also be seen that the handle 14 is knurled on the outside in order to enable better handling. The handle 14 is also axially secured in the dispenser wall 3 by means of a circumferential projection 19.

Alternativ zu dem dargestellten Ratschenmechanismus, ist es auch möglich, daß die Handhabe 14 einfach über eine Reibschluß mit der Spenderwandung 3 zusammenwirkt. Wenn der Reibschluß genügend stark gewählt ist, ist eine Rückdrehung der Handhabe 14 aufgrund von Rückstellkräften des Vorratsbehälters bei einer Verdrillung nicht möglich, so daß auch diese Ausführungsform ausreichend ist.As an alternative to the ratchet mechanism shown, it is also possible that the handle 14 simply interacts with the dispenser wall 3 via a frictional connection. If the frictional engagement is selected to be sufficiently strong, a return rotation of the handle 14 is not possible due to the restoring forces of the storage container during twisting, so that this embodiment is also sufficient.

Die Figuren 8 und 9 beziehen sich auf eine alternative Ausführungsform des Halterungsteils 8. Das Halterungsteil 8 besteht hierbei aus einer Schraubenfeder 20, die zur Übertragung eines Drehmomentes noch mit im wesentlichen senkrecht verlaufenden Querelementen 21 ausgebildet sind, die so vorgesehen sind, daß sie reißverschlußartig - bezüglich übereinander verlaufender Windungen der Schraubenfeder - ineinander greifen. Diese Schraubenfeder kann so bei einer zunehmenden Verdrillung des Vorratsbehältnisses dem Bodenende axial in der Höhe folgen, ohne die Fähigkeit zu verlieren, das erforderliche Drehmoment zu übertragen. Entsprechend ist es nicht erforderlich, das Bodenende 5 des Vorratsbehälters mit einer angepaßten Länge (Stababschnitt 6) auszubilden. In Fig. 9 ist ein Zustand dargestellt, bei welchem das Vorratsbehältnis bereits eine gewisse Verkürzung aufweist. Ein oberes Ende der Schraubenfeder 20 liegt in dem Boden des Vorratsbeutels 2 an einem Drehanschlag an, und ein unteres Ende ist mit der Handhabe 14 fest verbunden. Dies ist im einzelnen nicht dargestellt.FIGS. 8 and 9 relate to an alternative embodiment of the mounting part 8. The mounting part 8 here consists of a helical spring 20, which is still essentially perpendicular to the transmission of a torque extending transverse elements 21 are formed, which are provided such that they engage in a zipper-like manner - with respect to overlapping turns of the coil spring. This helical spring can thus follow the bottom end axially in height with increasing twisting of the storage container without losing the ability to transmit the required torque. Accordingly, it is not necessary to design the bottom end 5 of the storage container with an adapted length (rod section 6). 9 shows a state in which the storage container already has a certain shortening. An upper end of the coil spring 20 lies in the bottom of the storage bag 2 against a rotary stop, and a lower end is firmly connected to the handle 14. This is not shown in detail.

Fig. 10 zeigt eine weitere erfindungsgemäße Ausführungsform eines Spenders, wobei eine Verdrillung des Vorratsbeutels 2 durch axialen Druck des Gehäuses 3 auf ein Bodenteil 29 gegen eine Druckfeder 30 erreicht wird. Dabei läuft eine Schraube 32 in eine Mutter 31 auf den Boden 29. Die Schraube 32 ist an der Stelle 24c fest mit einer Drehhülse 24 verbunden, in der ein Mitnehmer 26, der an dem Vorratsbeutel 2 befestigt ist, axial verschiebbar angeordnet ist. Die Drehung der Schraube 32 bewirkt über die Drehung der Drehhülse 24 und den Mitnehmer 26 eine Verdrillung des Vorratsbeutels 2. Bei der dabei entstehenden Verkürzung des Vorratsbeutels 2 wird der Mitnehmer 26 in der Drehhülse 24 nach oben bewegt.10 shows a further embodiment of a dispenser according to the invention, wherein the storage bag 2 is twisted by axially pressing the housing 3 onto a base part 29 against a compression spring 30. A screw 32 runs into a nut 31 on the floor 29. The screw 32 is fixedly connected at the point 24c to a rotating sleeve 24, in which a driver 26, which is fastened to the storage bag 2, is arranged so as to be axially displaceable. The rotation of the screw 32 causes a twisting of the storage bag 2 via the rotation of the rotating sleeve 24 and the driver 26. When the storage bag 2 is shortened, the driver 26 is moved upward in the rotating sleeve 24.

Der Spender gemäß Fig. 10 weist einen Deckel 22 auf. Am Oberteil des Vorratsbeutels 2 ist ein Flansch 27 mit einem schrägen seitlichen Auslaßrohr 13 ausgebildet. Das Auslaßrohr 13 wird in entsprechenden Durchlässen des Deckels 22 und des Spendergehäuses 3 gehaltert und verhindert somit eine Drehung des Beutelflansches 27 im Spender. In dem in Fig. 10 dargestellten Ruhezustand des Spenders 1 ist die Öffnung des Auslaßrohres 13 mit einer Klappe 23 verschlossen. Die Klappe 23 ist gelenkig mit einem feststehenden Ring 25 im Inneren des Spendergehäuses 3 verbunden und wird durch eine Öffnung 3b des Spendergeäuses 3 geführt.10 has a cover 22. On the upper part of the storage bag 2, a flange 27 is formed with an oblique side outlet tube 13. The outlet tube 13 is held in corresponding passages of the cover 22 and the dispenser housing 3 and thus prevents the bag flange 27 from rotating in the dispenser. In the idle state of the dispenser 1 shown in FIG. 10, the opening of the outlet pipe 13 is closed by a flap 23. The flap 23 is articulated to a fixed ring 25 in the interior of the dispenser housing 3 and is guided through an opening 3b of the dispenser housing 3.

Fig. 11 zeigt die erfindungsgemäße Ausführungsform gemäß Fig. 10 ohne Vorratsbeutel 2 und ohne Deckel 22. Der Ring 22 ist vorzugsweise über 3 Stege 28 fest mit dem Boden 29 verbunden. Bei einem kreisförmigen Querschnitt des Spenders sind die Stege 28 in einem Winkelabstand von 120° angeordnet. Sie weisen vorzugsweise eine Breite von 12 mm auf. An den Stegen 28 sind Nasen 34 ausgebildet, die im Ruhezustand das Spendergehäuse 3 unter Druck der Feder 30 am Boden 29 haltern. Weiterhin ist das Drehgehäuse 24 abgebildet. Es weist Schlitze 24a auf, in die die Enden eines stabförmigen Mitnehmers 26 über Einführschrägen 24b eingeführt werden.FIG. 11 shows the embodiment according to the invention according to FIG. 10 without a storage bag 2 and without a lid 22. The ring 22 is preferably fixedly connected to the bottom 29 via 3 webs 28. With a circular cross section of the dispenser, the webs 28 are arranged at an angular distance of 120 °. They preferably have a width of 12 mm. Lugs 34 are formed on the webs 28, which hold the dispenser housing 3 under pressure from the spring 30 on the base 29 in the idle state. The rotary housing 24 is also shown. It has slots 24a into which the ends of a rod-shaped driver 26 are inserted via insertion bevels 24b.

Fig. 12 zeigt die Ausführungsform gemäß Fig. 10, wobei das Spendergehäuse 3 gegen die Kraft der Feder 30 bis zum Anschlag auf den Boden 29 gedrückt ist. Bei diesem Vorgang drehte sich die Schraube 32 in die Mutter 31 hinein und bewirkte eine Verdrillung des Beutels 2 (hier nicht dargestellt). Das Gewinde der Schraube und Mutter weist eine starke Steigung vorzugsweise 100 mm Höhe pro Umdrehung, auf. Aus der Hubhöhe ergibt sich die Dosiermenge, so daß die Hubhöhe an die zu spendende Substanz angepaßt wird. Das Herunterdrücken des Spendergehäuses 3 bewirkt eine Relativbewegung zu dem auf dem Boden 29 feststehenden Halterungsring 25 für die Klappe 23. Die Öffnung 3b verschiebt sich nach unten, die Klappe 23 hebt von der Öffnung des Auslaßrohres 13 ab und Substanz wird aus dem Vorratsbeutel 2 ausgegeben. Umgekehrt geht, wenn kein Betätigungsdruck mehr ausgeübt wird, unter dem Druck der Feder 30 das Spendergehäuse 3 in den Ruhezustand zurück, wobei es an die Nasen 34 der Stege 28 anschlägt. Gleichzeitig hebt die Öffnung 3b die Klappe 23 wieder an und verschließt somit das Auslaßrohr 13.FIG. 12 shows the embodiment according to FIG. 10, wherein the dispenser housing 3 is pressed against the force of the spring 30 until it stops on the bottom 29. During this process, the screw 32 turned into the nut 31 and caused the bag 2 to twist (not shown here). The thread of the screw and nut has a steep pitch, preferably 100 mm height per revolution. The dosing quantity results from the lifting height, so that the lifting height is adapted to the substance to be dispensed. Pressing down the dispenser housing 3 causes a relative movement to the retaining ring 25 for the flap 23, which is fixed on the bottom 29. The opening 3b moves downward, the flap 23 lifts off the opening of the outlet tube 13 and substance is dispensed from the storage bag 2. Conversely, when the actuating pressure is no longer exerted, the dispenser housing 3 returns to the rest state under the pressure of the spring 30, abutting the lugs 34 of the webs 28. At the same time, the opening 3b lifts the flap 23 again and thus closes the outlet pipe 13.

Fig. 13 zeigt die Ausführungsform gemäß Fig. 12 unmittelbar nach dem Entspannen der Feder 30. Die Mutter 31 ist nur in horizontaler Richtung formschlüssig mit dem Boden 29 verbunden. Daher wurde sie, noch auf der Schraube 32 aufgeschraubt, durch die Feder 30 mit nach oben angehoben. Durch ihr Eigengewicht schraubt sich dann die Mutter 31 wieder von der Schraube 32 ab und fällt auf den Boden 29 zurück, wo sie mit Vorsprüngen 31a in entsprechende Aussparungen 29a am Boden wieder in Formschluß kommt. Damit ist der Ruhezustand gemäß Fig. 10 wieder erreicht, und die Verdrillung kann durch eine weitere Druckbetätigung fortgesetzt und weitere Substanz dem Spender entnommen werden.FIG. 13 shows the embodiment according to FIG. 12 immediately after the spring 30 has been released. The nut 31 is positively connected to the bottom 29 only in the horizontal direction. Therefore, it was still screwed onto the screw 32 and lifted up by the spring 30. Due to its own weight, the nut 31 then unscrews again from the screw 32 and falls back onto the base 29, where it comes into positive engagement again with projections 31a in corresponding recesses 29a on the base. The rest state according to FIG. 10 is thus reached again, and the twisting can be continued by a further pressure actuation and further substance can be removed from the dispenser.

Die Figuren 14 bis 16 zeigen eine weitere erfindungsgemäße Ausführungsform, die insbesondere für ein stiftförmiges Produkt relativ fester Konsistenz wie ein Deo-Stick, Klebestift oder Wachsmalstift geeignet ist. Dabei ist der Vorratsbeutel 2 mit einer drehbaren Handhabe 14 mit einem Deckel 14a über eine teleskopartige Halterung 35, 36 verbunden, die es dem unteren Ende des Vorratsbeutels 2 gestattet, eine bei der Verdrillung auftretende Vertikalbewegung vorzunehmen.FIGS. 14 to 16 show a further embodiment according to the invention, which is particularly suitable for a stick-shaped product of relatively firm consistency, such as a deodorant stick, glue stick or crayon. The storage bag 2 is connected to a rotatable handle 14 with a lid 14a via a telescopic holder 35, 36, which allows the lower end of the storage bag 2 to perform a vertical movement that occurs during twisting.

Fig. 14 zeigt die weitere erfindungsgemäße Ausführungsform des Spenders 3 im Ruhezustand mit einer Verschlußkappe 39 auf dem Spendergehäuse 3 und einer Dichtung 40. Der Vorratsbeutel 2 wird durch den Flansch 27 formschlüssig im Spender gehaltert, der vorzugsweise einen ovalen Querschnitt aufweist. Am unteren Ende des Vorratsbeutels 2 ist ein Mitnehmer 26 angeordnet, der in einer Mitnehmerhülse 36 hinein mit Haken 26a eingerastet ist. Im Ruhezustand vor der Betätigung des Spenders ragen die Haken 26a etwas tiefer in die Mitnehmerhülse hinein, um so auftretende Toleranzen in der Beutelabmessung bzw. Füllung auszugleichen. Der Mitnehmer 26 ist an den Beutel 2 angeschweißt und ragt mit einem Stabilisierungsteil 26b in den Vorratsbeutel 2 hinein, wobei er in Kontakt mit der Substanz 41 kommt und so die Stellung des Mitnehmers stabilisiert. Die Handhabe 14 ist mit einer Nase 14b hinter einem Vorsprung 3a des Spendergehäuses 3 drehbar und vorzugsweise leicht federnd eingerastet. Dadurch wird vermieden, daß sich der Vorratsbeutel 2 selbständig wieder aufdrillt. Ein gewisse Schwergängigkeit der Handhabung 14 kann auch durch eine leichte Riffelung im Übergangsbereich zwischen der Handhabung 14 und dem Spendergehäuse 3 erreicht werden.14 shows the further embodiment of the dispenser 3 according to the invention in the idle state with a closure cap 39 on the dispenser housing 3 and a seal 40. The storage bag 2 is positively held in the dispenser by the flange 27, which preferably has an oval cross section. At the lower end of the storage bag 2, a driver 26 is arranged, which is snapped into a driver sleeve 36 with hooks 26a. In the idle state before the dispenser is actuated, the hooks 26a protrude somewhat deeper into the driving sleeve in order to compensate for tolerances that occur in the bag dimensions or filling. The driver 26 is welded to the bag 2 and projects with a stabilizing part 26b into the storage bag 2, coming into contact with the substance 41 and thus stabilizing the position of the driver. The handle 14 is with a nose 14b rotatable behind a projection 3a of the dispenser housing 3 and preferably snapped into place in a slightly resilient manner. This prevents the storage bag 2 from being untwisted automatically. A certain stiffness of the handling 14 can also be achieved by slight corrugation in the transition area between the handling 14 and the dispenser housing 3.

Fig. 15 zeigt die erfindungsgemäße Ausführungsform gemäß Fig. 14 ohne Kappe, wobei der Beutel 2 noch nicht in seiner Halterung befestigt ist. Der Beutel 2 ist vor dem Einsetzen vorzugsweise mit einer Originalitätssicherung 42 (Folie) bedeckt, die beim Einsetzen abgerissen wird. Der Mitnehmer 26 wird mit den Haken 26a in eine sternförmige Verzahnung 36a in der Mitnehmerhülse 36 eingesetzt, wobei die Haken 26a, wie bereits beschrieben und in Fig. 14 dargestellt, über die Verzahnung 36a hinausragen.FIG. 15 shows the embodiment according to the invention according to FIG. 14 without a cap, the bag 2 not yet being fastened in its holder. Before insertion, the bag 2 is preferably covered with a tamper-evident device 42 (film) which is torn off when it is inserted. The driver 26 is inserted with the hooks 26a into a star-shaped toothing 36a in the driving sleeve 36, the hooks 26a, as already described and shown in FIG. 14, projecting beyond the toothing 36a.

Fig. 16 zeigt die erfindungsgemäße Ausführungsform gemäß Fig. 14 in der Endstellung der Verdrillung des Beutels 2, d.h., wenn die Substanz 41 nahezu vollständig ausgegeben ist. Zu Beginn der Verdrillung wird der Mitnehmer 26 angehoben und die Haken 26a rasten unter die sternförmige Verzahnung 36a ein. Dabei schieben sich die Teleskophülse 35 und die Mitnehmerhülse 36 allmählich bis zu den Anschlägen 38 in den Nuten 37 nach oben.FIG. 16 shows the embodiment according to the invention according to FIG. 14 in the end position of the twisting of the bag 2, i.e. when the substance 41 has been almost completely dispensed. At the beginning of the twisting, the driver 26 is raised and the hooks 26a engage under the star-shaped toothing 36a. The telescopic sleeve 35 and the driving sleeve 36 gradually slide up to the stops 38 in the grooves 37.

Die Ausführungsformen gemäß den Figuren 1 bis 16 weisen Vorratsbeutel 2 mit Verjüngungen an ihrem unteren Teil auf, um eine Vorzugsstelle für den Beginn der Verdrillung festzulegen. In einer bevorzugten Ausführungsform sind die Spender im wesentlichen aus Kunststoff hergestellt.The embodiments according to FIGS. 1 to 16 have storage bags 2 with tapering on their lower part in order to determine a preferred location for the start of the twisting. In a preferred embodiment, the dispensers are essentially made of plastic.
