Abstract

A dispenser for paste-like substances is disclosed having a piston which is slidably disposed in a dispenser housing. The piston moves as the dispenser is being emptied toward a dispensing opening while being restrained from movement in the opposite direction. A press button is connected with a rod that extends through the piston and is coupled nonpositively with the piston through the intermediary of a locking device permitting the rod to move freely in one direction, but to carry the piston in the opposite direction. A membrane seals the end of the housing opposite the discharge opening. The piston rod is designed as a piercing tool for piercing the membrane.

Description

Die Erfindung bezieht sich auf einen Spender für pastöse Massen (M), mit im Spendergehäuse (1) verschieblich angeordnetem, bei der Spen­derentleerung in Richtung der Mundstücköffnung wandernden, in Gegenrichtung blockierten Kolben (2), und einer Drucktasten-Betäti­gungsfläche, die an einem Kopfstück des Spendergehäuses vorgesehen ist, wobei mit dem Kopfstück eine den Kolben (2) durchsetzende Stan­ge (4) gekuppelt ist, die unter Zwischenschaltung eines Gesperres kraftschlüssig mit dem Kolben (2) gekuppelt ist.The invention relates to a dispenser for pasty masses (M), with a piston (2) which is displaceably arranged in the dispenser housing (1) and moves in the opposite direction when the dispenser is emptied, and which is blocked in the opposite direction, and a pushbutton actuating surface which is attached to a headpiece of the dispenser housing is provided, with the head piece being coupled to a rod (4) which passes through the piston (2) and which is non-positively coupled to the piston (2) with the interposition of a locking mechanism.

Ein Spender dieser Art ist durch die DE-OS 30 45 048 der Anmelderin bekannt. Den bodenseitigen Abschluß des Spendergehäuses bildet der Kolben. Bei langen Lagerzeiten besteht die Gefahr, daß von dorther ein Antrocknen der Masse stattfindet, was unter Umständen zu Kompli­kationen bei der Restausgabe führt.A donor of this type is known from DE-OS 30 45 048 by the applicant. The piston forms the bottom end of the dispenser housing. With long storage times there is a risk that the mass will dry out from there, which may lead to complications in the remaining dispensing.

Aufgabe der Erfindung ist es, einen gattungsgemäßen Spender mit herstellungstechnisch einfachen Mitteln so auszubilden, daß selbst über längste Gebrauchszeiten trotz klimatisch extremen Verhältnissen ein Antrocknen vermieden wird.The object of the invention is to design a dispenser of the generic type with means that are simple to manufacture in such a way that drying over is avoided even over long periods of use in spite of extreme climatic conditions.

Gelöst ist diese Aufgabe durch die im Anspruch 1 angegebene Erfin­dung.This object is achieved by the invention specified in claim 1.

Die Unteransprüche sind vorteilhafte Weiterbildungen des erfindungsge­mäßen Spenders.The subclaims are advantageous developments of the dispenser according to the invention.

Zufolge solcher Ausgestaltung ist eine wirksame bodenseitige Absiege­lung des gefüllten Spendergehäuses realisiert. Die Lagerfähigkeit bleibt so über längste Zeiten erhalten. Die entsprechende diffusions­dichte Folie läßt sich bei einem entsprechend thermisch ansprechenden Kunststoffmaterial des Spendergehäuses völlig klebemittelfrei zuordnen. Die zugleich das Entstehen eines Vakuums vermeidende Zerstörung der Membran erfolgt in vorteilhafter Weise durch die Kolbenstange selbst, die dadurch eine weitere Funktion erhält, nämlich die eines Durchstoß­werkzeuges. Da das die Drucktasten-Betätigungsfläche aufweisende Kopfstück in der Regel von einer Schutzkappe überfangen ist, besteht auch nicht die Gefahr, daß ein ungewolltes Lochen der Membran ge­schieht. Eine die Lage der Membran sichernde Maßnahme besteht in vorteilhafter Weiterbildung darin, daß die Membran mittels eines auf das Spendergehäuse aufgesteckten Fußringes eingespannt ist. Endlich ergibt sich ein vorteilhaftes Merkmal der Erfindung noch dadurch, daß der Fußring eine Bodenwand unterhalb der Membran bildet und fluch­tend zur Kolbenstange eine Durchtrittsöffnung für diese ausbildet. Die entsprechende Abstützung der Membran ermöglicht den Einsatz einer hauchdünnen Folie, da diese eine praktisch ganzflächige Abstüt­zung auf der Bodenwand findet; andererseits kann die Membran auch nicht in Richtung der Aufstellfläche des Spendergehäuses ausweichen, so daß es ganz sicher zu der den Gebrauch freigebenden Start-Lo­chung kommt.As a result of such a configuration, an effective bottom-side sealing of the filled dispenser housing is realized. The shelf life is maintained over long periods. The corresponding diffusion-tight film can be assigned completely adhesive-free in the case of a corresponding thermally responsive plastic material of the dispenser housing. The destruction of the membrane, which at the same time prevents the formation of a vacuum, is advantageously carried out by the piston rod itself, which thereby has a further function, namely that of a piercing tool. Since the head piece having the pushbutton actuating surface is usually covered with a protective cap, there is also no risk of undesired perforation of the membrane. A measure securing the position of the membrane consists in an advantageous further development in that the membrane is clamped by means of a foot ring attached to the dispenser housing. Finally, an advantageous feature of the invention results from the fact that the foot ring forms a bottom wall below the membrane and, in alignment with the piston rod, forms a passage opening for the latter. The corresponding support of the membrane enables the use of a wafer-thin film, since this is practically supported over the entire surface of the bottom wall; on the other hand, the membrane cannot deflect in the direction of the installation surface of the dispenser housing, so that the start perforation which releases the use is quite certain.

Der Gegenstand der Erfindung ist nachstehend anhand eines zeichne­risch veranschaulichten Ausführungsbeispieles näher erläutert. Es zeigt

  • Fig. 1 den erfindungsgemäß ausgebildeten Spender im Vertikal­schnitt,
  • Fig. 2 die Unteransicht des Spendergehäuses bei noch nicht aufge­stecktem Fußring und
  • Fig. 3 eine Herausvergrößerung des Bodenbereichs des Spenders mit in die Lochungsstellung verlagertem Kolbenstangenende (diese Stellung ist in strichpunktierter Linienart wiedergegeben).
The subject matter of the invention is explained in more detail below on the basis of an illustrative embodiment. It shows
  • 1 the dispenser designed according to the invention in vertical section,
  • Fig. 2 is the bottom view of the dispenser housing with the foot ring not yet attached and
  • Fig. 3 is an enlargement of the bottom area of the dispenser with the piston rod end shifted into the perforated position (this position is shown in dash-dotted lines).

Das lang zylindrisch ausgebildete Gehäuse 1 des Spenders enthält einen Kolben 2. Dessen Randlippen 2' führen sich an der zylindri­schen Gehäuseinnenwandung 1'.The long, cylindrical housing 1 of the dispenser contains a piston 2. Its edge lips 2 'lead to the cylindrical housing inner wall 1'.

Der Kolben 2 ist ausschließlich in Entleerungsrichtung (Pfeil x) ver­lagerbar. Er trägt auf seiner dem aufstellseitigen Gehäuseende zuge­wandten Breitfläche ein erstes Gesperre G1. Es handelt sich um einen sogenannten Klemmodul 3 in Form eines radial ausgerichtete Zacken 3' aufweisenden Sternes aus Federstahl. Sein die Zackenenden umschreibender Durchmesser ist etwas größer als der lichte Durch­messer des Spendergehäuses 1, wodurch sich die Zackenenden als schräg stehende Stützfüße an der Gehäuseinnenwandung 1' entgegen der Richtung des Pfeiles x sperrend verhaken.The piston 2 can only be displaced in the direction of emptying (arrow x). It carries a first locking mechanism G1 on its wide surface facing the housing end on the installation side. It is a so-called clamping module 3 in the form of a radially oriented tooth 3 'having a star made of spring steel. Its diameter circumscribing the prong ends is somewhat larger than the clear diameter of the dispenser housing 1, as a result of which the prong ends hook on the housing inner wall 1 'against the direction of the arrow x as inclined support feet.

Im Zentrum bildet der Klemmodul 3 ein zweites Gesperre G 2 aus. Mit letzterem wirkt eine den Kolben 2 zentral durchsetzende Kolbenstange 4 zusammen. Die radial einwärts gerichteten Zacken 3" des Klemmo­duls 3 greifen an der Kolbenstange 4 an. In die Ebene projiziert, ist die von den Zacken 3'' belassene Durchtrittsöffnung kleiner als der Durchmesser der Kolbenstange 4.The clamping module 3 forms a second locking mechanism G 2 in the center. A piston rod 4, which penetrates the piston 2 centrally, interacts with the latter. The radially inwardly directed teeth 3 ″ of the clamping module 3 engage the piston rod 4. When projected into the plane, the passage opening left by the teeth 3 ″ is smaller than the diameter of the piston rod 4.

Das bodenseitige Ende 4' der Kolbenstange 4 ist zugespitzt. Die Spitze ist als Kegel 4'' gestaltet. Eine in Richtung des Pfeiles x erfolgende Bewegung der Kupplungsstange führt aufgrund der kraft­schlüssigen Kupplung zur Mitnahme des Kolbens 2. Zu dieser Mit­nahme des Kolbens bildet das Spendergehäuse 1 an der dem mit einem Fußring 5 bestückten Standsockel des Gehäuses gegenüberliegenden Seite eine Betätigungshandhabe aus. Es handelt sich um ein balgartig in Richtung des Kolbens 2 zusammendrückbares, sich wieder in seine Grundstellung aufrichtendes Kopfstück 6. Letzteres ist auf den abgesetzten, insofern verschmälerten Hals 7 des Spendergehäuses 1 aufgesteckt. Zufolge der hohen Elastizität bzw. Flexibilität des Kopf­stückes ist dieses über einen Ring/Nuteingriff gebrauchsstabil gehal­ten. Das Kopfstück 6 formt weiter eine querschnittsverringerte, kanalartige Spender-Mundstücköffnung 8. Letztere ist schnabelförmig gestaltet. Ihr vorzugsweise kreisrunder Öffnungsmund liegt in der Nähe der Erstreckungsrichtung der Gehäusewandung und ist für die Zeiten der Lagerhaltung mit Hilfe eines dichtschließenden Stopfens 9 verschlossen. Der Stopfen weist Topfform auf mit mundstücköffnungs­seitig gerichtetem Topfrand. Der Stopfen ist dadurch hoch flexibel und in seinem Dichtschluß optimiert.The bottom end 4 'of the piston rod 4 is tapered. The tip is designed as a 4 '' cone. A movement of the coupling rod in the direction of arrow x leads, due to the frictional coupling, to entrainment of the piston 2. For this entrainment of the piston, the dispenser housing 1 forms an actuating handle on the side of the housing which is equipped with a base ring 5. It is a bellows-like compressible in the direction of the piston 2, straightening back into its basic position 6. The latter is on the offset, narrowed neck 7 of the dispenser housing 1 attached. Due to the high elasticity and flexibility of the head piece, it is kept stable in use via a ring / groove engagement. The head piece 6 further forms a cross-sectional, channel-like dispenser mouthpiece opening 8. The latter is designed in the form of a beak. Its preferably circular opening mouth lies in the vicinity of the direction of extension of the housing wall and is closed with the help of a tightly closing plug 9 for storage periods. The stopper has the shape of a pot with the rim of the pot directed towards the mouthpiece opening. The plug is therefore highly flexible and its tight closure is optimized.

Das Kopfstück 6 bildet desweiteren im Rücken des die Mundstücköff­nung 8 umschreibenden, schnabelartigen Fortsatzes in seiner Decken­partie eine Drucktasten-Betätigungsfläche 10 aus. Letztere reicht bis kurz vor die gegenüberliegende, gedanklich verlängerte Gehäuse-Wan­dungsebene und steigt nach außen schräg an.The head piece 6 furthermore forms a push-button actuation surface 10 in the back of the beak-like extension circumscribing the mouthpiece opening 8. The latter extends until just before the opposite, mentally extended housing wall level and rises outwards at an angle.

Unterhalb dieser Drucktasten-Betätigungsfläche 10 ist die das Spender­gehäuse 1 in der Längsmittelachse y-y durchsetzende Kolbenstange 4 mit dem Kopfstück 6 verbunden. Das Kopfstück 6 bildet dazu unter­halb dieser Drucktasten-Betätigungsfläche 10 gehäuseeinwärts gerichtet eine Rastvertiefung 11 aus, in die das pilzkopfartig verbreiterte obere Ende 4''' eingeschnäppert ist. Die Rastvertiefung 11 bildet zur er­leichterten Klipszuordnung kolbenseitig eine trichterförmige Erweite­rung aus.Below this pushbutton actuation surface 10, the piston rod 4 passing through the dispenser housing 1 in the longitudinal central axis y-y is connected to the head piece 6. For this purpose, the head piece 6 forms, below this pushbutton actuating surface 10, a latching recess 11 directed into the housing, into which the mushroom head-like widened upper end 4 '' 'is snapped. The latching recess 11 forms a funnel-shaped extension on the piston side for easier clip assignment.

In einem geringen Abstand vor der Rastvertiefung 11 besitzt die Kolbenstange einen Ringwulst 12. Letzterer begrenzt den Betätigungs­hub H der Kolbenstange 4, indem er gegen die Oberseite einer naben­artigen Hülse 13 im Hals 7 des Spendergehäuses 1 tritt. Die Hülse ist über speichenartige Radialrippen 14 mit dem Hals 7 verbunden. Die führend wirkende Büchse 13 schließt im wesentlichen mit der Oberseite des Halsendes ab und ragt etwa hälftig in den Hals, d. h. in seine Öffnung hinein.At a short distance from the locking recess 11, the piston rod has an annular bead 12. The latter limits the actuation stroke H of the piston rod 4 by stepping against the top of a hub-like sleeve 13 in the neck 7 of the dispenser housing 1. The sleeve is connected to the neck 7 via spoke-like radial ribs 14. The guide bushing 13 essentially closes with the top of the neck end and protrudes about half into the neck, ie into its opening.

Während das kopfstückseitige Ende des Spenders über den Stopfen 9 wirksam abgedichtet ist, übernimmt im Bodenbereich des Spenderge­häuses eine Membran 15 die luftdichte Abschließung, so daß auch von dorther kein Antrocknen der pastösen Masse mehr möglich ist. Die Membran 15 wird durch Klebung, Heißsiegeln oder dergleichen mit dem Stirnrand 1'' des Spendergehäuses verbunden.While the end of the dispenser at the head end is effectively sealed by the stopper 9, a membrane 15 takes over the airtight seal in the bottom area of the dispenser housing, so that from there it is no longer possible to dry the pasty mass. The membrane 15 is connected to the end edge 1 ″ of the dispenser housing by adhesive bonding, heat sealing or the like.

Bei Selbstbetätigung der Drucktasten-Betätigungsfläche 10 wird die Membran 15 zerstört. Hierzu ist die Kolbenstange unter Erfüllung einer entsprechenden Zusatzfunktion als Durchstoßwerkzeug gestaltet und am Ende entsprechend angespitzt (Kegel 4''). Die Kegelspitze liegt in einem Abstand z vor der Membran 15 (vergl. Fig. 3), welcher kleiner ist als der maximale, anschlagdefinierte Betätigungshub H der Kolbenstange 4. Daher kommt es zu einer zentralen Lochung, so daß die Entstehung eines Vakuums unterhalb des Kolbens 2 verhindert wird.The membrane 15 is destroyed when the pushbutton actuation surface 10 is actuated. For this purpose, the piston rod is designed as a piercing tool while fulfilling a corresponding additional function and is accordingly sharpened at the end (cone 4 ''). The cone tip lies at a distance z in front of the membrane 15 (see FIG. 3), which is smaller than the maximum, stroke-defined actuation stroke H of the piston rod 4. Therefore, there is a central perforation, so that a vacuum is created below the piston 2 is prevented.

Wie Fig. 3 weiter entnehmbar, ist die Membran 15 mittels des auf das Spendergehäuse aufgesteckten Fußringes 5 eingespannt. Der Fußring hat außen die Form eines flachen Kegelstumpfes. Sein abwärts gerich­teter, zylindrischer Standrand 5' bringt eine verbreiterte Standfläche für den Spender und damit eine erhöhte Standsicherheit. Die Steck­zuordnung kann durch Aufprellen des Fußringes 5 realisiert sein. Beim Ausführungsbeispiel ist jedoch eine Rastverbindung bevorzugt. Dazu weist die Mantelfläche des zylindrischen Spendergehäuses einen ringförmigen Vorsprung 16 auf. Letzterer tritt in eine passende Ringnut 17. Die Ringnut 17 befindet sich in einer ebenfalls zylin­drischen Ringwand 5'' des Fußringes, welche unten in eine horizontale Bodenwand 5''' übergeht. Deren innere Randpartie ist zur peripheren Einspannbefestigung herangezogen, während die sich unmittelbar unterhalb der Membran 15 erstreckende Bodenwand 5''' die Membran nach unten hin abstützt.As can also be seen in FIG. 3, the membrane 15 is clamped in place by means of the foot ring 5 fitted onto the dispenser housing. The foot ring has the shape of a flat truncated cone on the outside. Its downward-facing, cylindrical standing edge 5 'brings a widened standing area for the dispenser and thus increased stability. The plug-in assignment can be realized by opening the foot ring 5. In the embodiment, however, a snap connection is preferred. For this purpose, the outer surface of the cylindrical dispenser housing has an annular projection 16. The latter enters a matching annular groove 17. The annular groove 17 is located in a likewise cylindrical ring wall 5 ″ of the foot ring, which merges into a horizontal bottom wall 5 ″ ″ at the bottom. Its inner edge is used for peripheral clamping, while the immediate below the membrane 15 extending bottom wall 5 '''supports the membrane downwards.

Fluchtend zur Kolbenstange 4 läßt die Bodenwand 5''' eine Durchtritts­öffnung 18 für das Durchstoßwerkzeug frei. Dabei erstreckt sich die Bodenwand 5''' in einem solchen vertikalen Abstand zur bspw. von einer Konsole gebildeten Aufstellfläche F, daß die Spitze des Kegels 4'' diese Fläche nicht berührt. Die Ausgabe kann also bei stehendem Spender erfolgen.In alignment with the piston rod 4, the bottom wall 5 '' 'leaves a passage opening 18 for the piercing tool. The bottom wall 5 ″ ″ extends at such a vertical distance from the installation surface F, for example formed by a bracket, that the tip of the cone 4 ″ does not touch this surface. The dispensing can therefore take place with the donor standing.

Um den Einschluß von Luft vor dem Kolben möglichst zu vermeiden, weist das zuordnungsseitige, untere Ende des Spendergehäuses einen größeren lichten Durchmesser auf, als der längere Restabschnitt des­selben (vergl. Stufe 20).In order to avoid the inclusion of air in front of the piston as much as possible, the lower end of the dispenser housing on the assignment side has a larger clear diameter than the longer remaining section of the same (see step 20).

Das Kopfstück 6 ist von einer Kappe 19 überfangen. Letztere hält reibungs- oder formschlüssig an einer peripheren Wulst im Befesti­gungsbereich derselben zwischen unterem Kopfstückrand und Hals 7 des Spendergehäuses 1. Die zylindrische Innenwand 19' der Kappe 19 sichert die Lage des sich mit seinem Rücken an ihr abstützenden Stopfens 9.The head piece 6 is covered by a cap 19. The latter holds frictionally or positively on a peripheral bead in the fastening area thereof between the lower edge of the headpiece and the neck 7 of the dispenser housing 1. The cylindrical inner wall 19 'of the cap 19 secures the position of the stopper 9 which is supported on it with its back.

Die funktion des Spenders ist, kurz zusammengefaßt, wie folgt:
Nach Abnehmen der Kappe 19 und Niederdrücken der Betätigungsfläche 10 locht die Kolbenstange 4 mit ihrem zugespitzten Ende die Membran 15. Unter Loslassen der Betätigungsfläche wird über den Klemmodul der Kolben 2 in Richtung des Mundstückes verlagert und so die pa­stöse Masse in den gewünschten Schritten ausgebracht. Hinter dem Kolben kann sich zufolge der Lochung kein Vakuum bilden. Die Lo­chung schließt sich bei entsprechend rückstellfähigem Membran-Material sogar klappventilartig wieder.Briefly, the function of the donor is as follows:
After removing the cap 19 and depressing the actuating surface 10, the piston rod 4 punctures the membrane 15 with its pointed end. When the actuating surface is released, the piston 2 is displaced in the direction of the mouthpiece via the clamping module and the paste-like mass is thus applied in the desired steps. Due to the perforation, no vacuum can form behind the piston. If the membrane material is resettable, the perforation even closes again like a folding valve.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestell­ten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
