Description

Die Erfindung betrifft eine Nachfüllpatrone für einen durch Bestreichen einer Oberfläche Produkt abgebenden Stift, wie Klebestift, mit einem hülsenförmigen Element, welches beidseitig endseitig dicht verschließbar ist und mit einem Ende zum dichten Aufsetzen auf ein Hülsenelement des Stiftes ausgebildet ist, wobei im hülsenförmigen Element verdrehsicher geführt ein in Längsrichtung verschiebbarer Kolben mit einer Gewindebohrung angeordnet ist, in welche eine aus dem Hülsenelement herausragende Gewindespindel des Klebestiftes einschraubbar ist, wobei das hülsenförmige Element mit einer Produktmasse gefüllt ist, welche endseitig am Kolben anliegt und in Verlängerung der Gewindebohrung eine durchgehende Bohrung aufweist, in welche im auf den Stift aufgesetzten Zustand der Nachfüllpatrone die Gewindespindel eingreift sowie ein Verfahren zum Befüllen einer solchen Nachfüllpatrone mit Zunächst fließfähiger, anschließend erstarrender Produktmasse, bei welchem in die bodenseitig verschlossene, mit dem Kolben ausgerüstete Nachfüllpatrone Produkt eingegossen wird.The invention relates to a refill cartridge for a Brushing a surface product-releasing pen, such as Glue stick, with a sleeve-shaped element, which is on both sides is sealable at one end and with one end for tight placement on a sleeve element of the pin is formed, wherein in the sleeve-shaped element against rotation guided a piston displaceable in the longitudinal direction is arranged with a threaded bore into which one the threaded spindle of the glue stick protruding from the sleeve element can be screwed in, the sleeve-shaped element is filled with a product mass which ends on Piston abuts and an extension of the threaded bore has through hole in which on the pin attached state of the refill cartridge the threaded spindle intervenes and a method for filling such Refill cartridge with initially flowable, then more solidified Product mass, in which in the bottom sealed refill cartridge equipped with the piston Product is poured.

Nachfüllpatronen dieser Art sowie ein entsprechendes Verfahren zum Befüllen derselben sind aus der DE 41 20 969 A1 der Anmelderin sowie auch aus der DE 41 16 581 A1 bekannt. Refill cartridges of this type and a corresponding procedure for filling the same are from DE 41 20 969 A1 the applicant and also known from DE 41 16 581 A1.

Sie eignen sich insbesondere zum Nachfüllen von Klebestiften, aber auch von anderen, durch Bestreichen einer Oberfläche Produkt abgebenden Stiften, wie Deo-, Lippen-, Trennmittel-, Rasierseifen- oder Farbstiften. Wesentlicher Vorteil dieser Nachfüllpatronen ist, daß nach der Entleerung eines derartigen Stiftes dieser mit seinen wesentlichen, sich nicht verbrauchenden Teilen mehrmals wiederverwendet werden kann, indem er mit einer Nachfüllpatrone quasi wiederbefüllt wird, wozu die zunächst geschlossene Nachfüllpatrone auf den Stift aufgesetzt und an diesem befestigt wird, wobei die Schraubspindel des Stiftes in die Nachfüllpatrone eingeführt und in den Kolben eingeschraubt wird und anschließend dann in die durchgehende Bohrung in der Produktmasse der Nachfüllpatrone eingreifen kann.They are particularly suitable for refilling glue sticks, but also by others, by painting a surface Product dispensing pens, such as deodorant, lip, Release agent, shaving soap or colored pencils. More essential The advantage of these refill cartridges is that after emptying such a pin with its essential, parts that are not used are reused several times can be done by using a refill cartridge is almost refilled, which is why the initially closed Refill cartridge placed on the pen and attached to it is, the screw spindle of the pin in the Refill cartridge inserted and screwed into the plunger and then into the through hole in the product mass of the refill cartridge can intervene.

Bietet eine solche Nachfüllpatrone schon erhebliche Vorteile, so hat sich doch herausgestellt, daß die Herstellung bzw. Befüllung einer solchen Nachfüllpatrone mit zunächst flüssiger Produktmasse im Hinblick auf die Notwendigkeit der Ausbildung einer durchgehenden Bohrung zur Aufnahme der Gewindespindel mit Nachteilen verbunden ist. Gemäß dem aus DE 41 20 969 A1 bekannten Verfahren ist nämlich vorgesehen, daß zunächst die bodenseitig verschlossene leere Nachfüllpatrone in eine Gießform eingebracht wird, in welche dann im Grund der Gießform konzentrisch zur Längsachse ein sich über die Gießform erstreckender Stift zur Aufnahme der Gewindebohrung des Kolbens und zur Ausbildung der durchgehenden Bohrung in der Produktmasse angeordnet wird, worauf dann die Produktmasse eingegossen wird und anschließend nach dem Erstarren der die durchgehende Bohrung bildende Stift wieder entfernt werden muß. Anschließend ist es dann erforderlich, die Nachfüllpatrone beidseitig an den Enden dicht zu verschließen, damit die Produktmasse nicht in Kontakt mit der Umgebungsluft kommen kann.Such a refill cartridge already offers considerable advantages, So it turned out that the production or filling such a refill cartridge with initially liquid product mass in terms of necessity the formation of a through hole to accommodate the Threaded spindle is associated with disadvantages. According to that The method known from DE 41 20 969 A1 is namely provided that first the empty refill cartridge, which is closed on the bottom is placed in a mold, in which then in the base of the mold concentric to the longitudinal axis Pin extending over the mold to receive the threaded hole of the piston and for the formation of the continuous Hole is placed in the product mass, whereupon then the product mass is poured in and then after solidification, the one forming the through hole Pen must be removed again. Then it is then required, the refill cartridge on both ends close tightly so that the product mass does not come into contact can come with the ambient air.

Aufgabe der Erfindung ist es deshalb, eine Lösung zu schaffen, mit der eine derartige Nachfüllpatrone auf einfachere Weise hergestellt bzw. befüllt werden kann, wobei eine einwandfreie Abdichtung nach der Befüllung gewährleistet sein soll.The object of the invention is therefore to create a solution with such a refill cartridge to simpler Way can be made or filled, with a flawless Sealing after filling must be guaranteed should.

Diese Aufgabe wird bei einer Nachfüllpatrone der eingangs bezeichneten Art erfindungsgemäß dadurch gelöst, daß das hülsenförmige Element am freien Ende lösbar mit einem dichtend aufgesetzten kappenförmigen Verschlußelement verschlossen ist, wobei das kappenförmige Verschlußelement innenseitig einen die durchgehende Bohrung der Produktmasse ausfüllenden stiftartigen Ansatz aufweist.This task is the beginning of a refill cartridge designated type solved according to the invention in that the sleeve-shaped element at the free end detachable with a sealing attached cap-shaped closure element closed is, the cap-shaped closure element on the inside a through hole of the product mass filling pen-like approach.

Bei einer derartigen Gestaltung der Nachfüllpatrone ist deren Herstellung und Befüllung auf wesentlich einfachere Weise möglich. Es kann nämlich zunächst in die bodenseitig geschlossene Nachfüllpatrone die Produktmasse in flüssiger Form eingefüllt werden, worauf dann nachfolgend das kappenförmige Verschlußelement dichtend aufgesetzt wird, wobei der stiftartige Ansatz dann im noch flüssigen Zustand der Produktmasse die gewünschte durchgehende Bohrung in der Produktmasse ausbildet. Dabei ist die Länge des stiftartigen Ansatzes selbstverständlich so gewählt, daß eine durchgehende Bohrung entsteht. Wenn die Nachfüllpatrone beim Benutzer eingesetzt werden soll, ist es lediglich erforderlich, das kappenförmige Verschlußelement von der Nachfüllpatrone zu entfernen, worauf dann die durchgehende Bohrung in der starren Produktmasse freigegeben wird.With such a design of the refill cartridge is Manufacturing and filling on much easier Way possible. It can namely in the bottom side closed refill the product mass in liquid Form are filled, followed by the cap-shaped Closure element is placed sealingly, wherein the pen-like approach then in the still liquid state of the The desired through hole in the product Forms product mass. The length of the pen-like Approach of course chosen so that a continuous Hole is created. When the refill cartridge is with the user to be used, it is only necessary the cap-shaped closure element from the refill cartridge then remove the through hole is released in the rigid product mass.

In besonders vorteilhafter Ausgestaltung ist vorgesehen, daß der stiftartige Ansatz so lang ausgebildet ist, daß das freie Ende des stiftartigen Ansatzes in vollständig aufgesetztem Zustand des kappenförmigen Verschlußelementes in die Gewindebohrung des Kolbens wenigstens bereichsweise eingreift. Es ist dadurch gewährleistet, daß auch die Gewindebohrung des Kolbens weitgehend frei von Produktmasse ist, so daß bei der Verwendung der Nachfüllpatrone auf einfache Weise ein Einschrauben der Gewindespindel des Stiftes möglich ist.In a particularly advantageous embodiment, that the pen-like approach is so long that the free end of the pin-like approach in completely put on State of the cap-shaped closure element in the threaded bore of the piston at least in some areas intervenes. This ensures that the threaded hole of the piston largely free of product mass is so that when using the refill cartridge on simple Way screwing in the threaded spindle of the pin is possible.

Insbesondere vorteilhaft ist es, wenn das kappenförmige Verschlußelement und/oder der äußere Aufsetzbereich des hülsenförmigen Elementes für das kappenförmige Verschlußelement mit zusammenwirkenden umlaufenden Rastmitteln versehen sind, die derart ausgebildet sind, daß vor dem Überfahren der Rastmittel der stiftartige Ansatz die Produktmasse vollständig durchdringt. Auf diese Weise läßt sich die gewünschte durchgehende Gewindebohrung zweistufig herstellen, indem nach dem Befüllen zwecks Luftausgleich die Verschlußkappe mit stiftartigem Ansatz zunächst lose aufgesetzt wird, wobei eine mittige Zentrierung des stiftartigen Ansatzes durch das kappenförmige Verschlußelement und durch das Eintauchen der Spitze des stiftartigen Ansatzes in den Gewindebereich des Kolbens erfolgt. Nach dem Erkalten der Füllung wird dann durch Druck auf das kappenförmige Verschlußelement und durch Überfahren der Rastmittel ein dichter Abschluß und zugleich ein weiteres Eindringen des stiftartigen Ansatzes in den Kolbengewindebereich erreicht, wobei geringe Füllungsanteile im Gewindebereich seitlich vorbei an der Spitze des stiftartigen Ansatzes verdrängt werden.It is particularly advantageous if the cap-shaped Closure element and / or the outer placement area of the sleeve-shaped element for the cap-shaped closure element provided with interacting circumferential locking means are designed such that before being run over the locking means the pin-like approach the product mass completely penetrated. In this way produce the desired continuous threaded hole in two stages, after filling for the purpose of air balance Cap with pin-like approach is initially loosely attached is, with a central centering of the pin-like Approach through the cap-shaped closure element and through dipping the tip of the pen-like approach into the Threaded area of the piston takes place. After cooling the The filling is then pressed onto the cap-shaped closure element and a tight one by driving over the locking means Conclusion and further penetration of the pin-like approach reached in the piston thread area, with small fillings in the thread area on the side displaced past the tip of the pen-like approach will.

Besonders vorteilhaft ist es, wenn das kappenförmige Verschlußelement flexibel und der stiftartige Ansatz hart ausgebildet sind, um einerseits eine gute Abdichtung zwischen dem kappenförmigen Ansatz und dem hülsenförmigen Element der Nachfüllpatrone zu erreichen und andererseits ein einwandfreies Durchdringen der Produktmasse mittels des stiftartigen Ansatzes.It when the cap-shaped closure element is particularly advantageous flexible and the pen-like approach is hard trained are on the one hand a good seal between the cap-shaped neck and the sleeve-shaped element to reach the refill cartridge and on the other hand a perfect one Penetration of the product mass by means of the pin-like Approach.

Um Materialanhäufungen zu vermeiden, sind vorzugsweise das kappenförmige Verschlußelement und der stiftartige Ansatz zweiteilig, lösbar miteinander verbindbar ausgebildet.In order to avoid material accumulation, this is preferred cap-shaped closure element and the pin-like approach two-part, detachably connectable.

Ganz besonders vorteilhaft ist es, wenn die Gewindebohrung des Kolbens und/oder die zugeordnete Öffnung im Boden des hülsenförmigen Elementes mit einer Schutzfolie oder dergl. verschlossen sind. Dabei dichtet dann die Schutzfolie oder Dünnstelle im Behälterboden die Nachfüllpatrone nach außen ab, während die Schutzfolie im Bereich der Gewindebohrung des Kolbens verhindert, daß beim Einfüllen des flüssigen Produktes dieses ganz in den Bereich des Gewindes gelangen und dieses verstopfen kann.It is particularly advantageous if the threaded hole of the piston and / or the associated opening in the bottom of the sleeve-shaped element with a protective film or the like. are closed. The protective film or seals Thin out the refill cartridge in the bottom of the container off while the protective film in the area of the threaded hole of the piston prevents that when filling the liquid Of this product reach the area of the thread and can clog it.

Je nach den Füllmaterialien kann vorteilhaft vorgesehen sein, daß das freie Ende des stiftartigen Ansatzes spitz zulaufend, konisch oder stufenförmig ausgebildet ist.Depending on the filling materials can be advantageously provided be that the free end of the pen-like approach is pointed tapered, conical or stepped.

In weiterer vorteilhafter Ausgestaltung ist vorgesehen, daß das hülsenförmige Element mit wenigstens einer außenseitigen Längsrille versehen ist. Diese Längsrille wirkt mit einem innenseitig am Hülsenelement des Stiftes vorgesehenen Steg zusammen und bietet einen Verdrehschutz, wie dies an sich aus der Fig. 6 der DE 41 16 581 A1 bekannt ist.In a further advantageous embodiment it is provided that the sleeve-shaped element with at least one outside Longitudinal groove is provided. This longitudinal groove takes part one provided on the inside of the sleeve element of the pin Bridge together and offers anti-twist protection like this is known from FIG. 6 of DE 41 16 581 A1.

Zur Lösung der eingangs gestellten Aufgabe sieht die Erfindung auch ein Verfahren zum Befüllen einer vorbeschriebenen Nachfüllpatrone mit zunächst fließfähiger, anschließend erstarrender Produktmasse vor, bei welchem in die bodenseitig verschlossene, mit dem Kolben ausgerüstete Nachfüllpatrone Produkt eingegossen wird, wobei sich dieses Verfahren dadurch auszeichnet, daß nach dem Eingießen des Produktes vor dessen Erstarrung das kappenförmige Verschlußelement auf das entsprechende Ende des hülsenförmigen Elementes aufgesetzt wird, derart, daß der stiftartige Ansatz vollständig in die fließfähige Produktmasse unter Bohrungsausbildung eindringt.The invention provides a solution to the problem set out at the beginning also a method for filling a previously described Refill cartridge with initially flowable, then solidifying Product mass before, in which in the bottom sealed refill cartridge equipped with the piston Product is poured in, this procedure distinguishes that after pouring the product before its solidification on the cap-shaped closure element put the corresponding end of the sleeve-shaped element is such that the pen-like approach is complete into the flowable product mass under drilling penetrates.

In besonders vorteilhafter Ausgestaltung ist dabei vorgesehen, daß das kappenförmige Verschlußelement zunächst so weit auf das hülsenförmige Element aufgesetzt wird, daß das freie Ende des stiftartigen Ansatzes nur bis in den Bereich der Gewindebohrung des Kolbens hineinragt und daß nach dem Erstarren der Produktmasse das kappenförmige Verschlußelement durch Überfahren der Rastmittel vollständig dichtend auf das hülsenförmige Element aufgesetzt wird. Dadurch ist dann zunächst bei der Befüllung ein Luftausgleich, d.h. ein Entweichen von Luft nach außen möglich, worauf nachfolgend nach der Erstarrung ein dichter Abschluß der Nachfüllpatrone erfolgt.In a particularly advantageous embodiment, that the cap-shaped closure element initially so is placed far on the sleeve-shaped element that the free end of the pen-like approach only in the area the threaded hole of the piston protrudes and that after the The cap-shaped closure element solidifies the product mass completely sealed by driving over the locking means is placed on the sleeve-shaped element. This is then first an air balance during filling, i.e. a Escaping air to the outside is possible, which follows after solidification, a tight seal of the refill cartridge he follows.

Eine erfindungsgemäße Nachfüllpatrone für einen durch Bestreichen einer Oberfläche Produkt abgebenden Stift ist in der Zeichnung allgemein mit 1 bezeichnet. Diese Nachfüllpatrone 1 ist im dargestellten Ausführungsbeispiel zum Nachfüllen eines Klebestiftes vorgesehen, wobei sie nach dem Aufsetzen bzw. Verbinden mit dem Klebestift einen Bestandteil des Klebestiftes bildet, dieser Klebestift ist deshalb insgesamt, die Nachfüllpatrone 1 enthaltend, mit 2 bezeichnet. Anstelle eines Klebestiftes 2 eignet sich eine erfindungsgemäße Nachfüllpatrone auch für andere Produktstifte, die durch Bestreichen einer Oberfläche in geringer Menge Produkt an die Oberfläche abgeben können, z.B. kann es sich auch um ein Deo-, Lippen-, Trennmittel, Rasierseifen- oder Farbstift handeln. Der Übersichtlichkeit halber wird nachfolgend jedoch nur auf einen Klebestift bzw. auf eine Klebstoffmasse Bezug genommen.A refill cartridge for one by brushing a surface donating pen is in the drawing generally designated 1. This refill cartridge 1 is in the illustrated embodiment for refilling an adhesive stick provided, according to the Attaching or connecting a component with the glue stick of the glue stick, this glue stick is therefore overall, containing the refill cartridge 1, labeled 2. Instead of an adhesive stick 2, an inventive one is suitable Refill cartridge also for other product pens, by painting a surface in a small amount Release product to the surface, e.g. it can also a deodorant, lip, release agent, shaving soap or Act colored pencil. For the sake of clarity, the following is however only on a glue stick or on an adhesive mass Referred.

Der Klebestift 2 weist, abgesehen von der Nachfüllpatrone 1, die Bestandteil des Klebestiftes 2 ist, ein Hülsenelement 3 mit einem geschlossenen Boden 4 auf, welcher in eine umlaufende Schnappverbindung 5 zur Aufnahme einer Rändelmutter 6 mit nach oben aus dem Hülsenelement 3 herausragender Gewindespindel 7 übergeht. Das Hülsenelement 3 erweitert sich nach oben zu seinem Ende hin, dieser Bereich ist mit 3a bezeichnet und weist innenseitig ein Innengewinde 8 zur Befestigung des entsprechenden Endes der Nachfüllpatrone 1 auf, wozu die Nachfüllpatrone 1 mit einem korrespondierenden Außengewinde 9 versehen ist.The glue stick 2 has, apart from the refill cartridge 1, which is part of the glue stick 2, a sleeve element 3 with a closed bottom 4, which in a circumferential snap connection 5 for receiving a knurled nut 6 with the sleeve element 3 protruding upwards Threaded spindle 7 passes. The sleeve element 3 expanded up towards its end, that area is designated 3a and has an internal thread 8 on the inside for fastening the corresponding end of the refill cartridge 1 on what the refill cartridge 1 with a corresponding External thread 9 is provided.

Die Nachfüllpatrone 1 selbst weist ein hülsenförmiges Element 10 mit einem weitgehend geschlossenen Boden 11 auf, welcher zentral mit einer Dünnstelle, einer Durchdrückstelle oder dergl. versehen ist, welche in Fig. 2 mit 22 bezeichnet ist. Innerhalb der Nachfüllpatrone 1 ist ein im hülsenförmigen Element 10 verdrehsicher geführter (was im einzelnen nicht dargestellt ist), in Längsrichtung verschiebbarer Kolben 12 mit Gewindebohrung 13 angeordnet, wobei die Gewindebohrung 13 mit dem Außengewinde 14 der Gewindespindel 7 des Klebestiftes 1 korrespondiert. Oberhalb des Kolbens 12 ist das hülsenförmige Element 10 der Nachfüllpatrone 1 mit einer Klebstoffmasse 15 gefüllt, wobei diese Klebstoffmasse 15 in Verlängerung der Gewindebohrung 13 des Kolbens 12 mit einer durchgehenden Bohrung 16 versehen ist.The refill cartridge 1 itself has a sleeve-shaped element 10 with a largely closed base 11, which is central with a thin point, a push-through point or the like. Which is 22 in FIG is designated. Inside the refill cartridge 1 is a sleeve-shaped element 10 guided against rotation (which in individual is not shown), displaceable in the longitudinal direction Piston 12 is arranged with a threaded bore 13, wherein the threaded bore 13 with the external thread 14 of the threaded spindle 7 of the glue stick 1 corresponds. Above the piston 12 is the sleeve-shaped element 10 of the refill cartridge 1 filled with an adhesive mass 15, wherein this adhesive mass 15 in the extension of the threaded bore 13 of the piston 12 is provided with a through bore 16 is.

Wie am besten aus den Fig. 3 bis 5 hervorgeht, weist die Nachfüllpatrone 1 darüber hinaus ein kappenförmiges Verschlußelement 17 auf, welches von außen auf das freie Ende des hülsenförmigen Elementes 10 aufsetzbar ist. Dabei ist das kappenförmige Verschlußelement 17 innenseitig mit einem stiftartigen Ansatz 18 versehen, dessen Länge so gewählt ist, daß das freie Ende 19 des stiftartigen Ansatzes 18 in vollständig aufgesetztem Zustand des kappenförmigen Verschlußelementes 17 in die Gewindebohrung 13 des Kolbens 12 wenigstens bereichsweise eingreift.As best seen in FIGS. 3 to 5, the Refill cartridge 1 also has a cap-shaped closure element 17 on which from the outside to the free end of the sleeve-shaped element 10 can be placed. It is the cap-shaped closure element 17 on the inside with a provided pin-like approach 18, the length of which is chosen is that the free end 19 of the pin-like projection 18 in fully fitted state of the cap-shaped closure element 17 into the threaded bore 13 of the piston 12 intervenes at least in certain areas.

Das kappenförmige Verschlußelement 17 und der äußere Aufsatzbereich des hülsenförmigen Elementes 10 für das kappenförmige Verschlußelement 17 sind mit zusammenwirkenden umlaufenden Rastmitteln 20, 21 versehen, die im dargestellten Ausführungsbeispiel als umlaufende Schnappwülste ausgebildet sind. Hier könnte aber auch eine andere Ausbildung, z.B. eine Schraubrastverbindung vorgesehen sein. Diese Rastmittel 20, 21 dienen dazu, daß das kappenförmige Verschlußelement 17 zunächst in einer ersten Aufsetzposition auf das hülsenförmige Element 10 aufgesetzt werden kann (Fig. 3) und erst anschließend nach Überfahren der Rastmittel 21 über die Rastmittel 20 ein vollständiges dichtes Aufsetzen des kappenförmigen Verschlußelements 17 auf das hülsenförmige Element 10 erfolgt.The cap-shaped closure element 17 and the outer attachment area of the sleeve-shaped element 10 for the cap-shaped Closure element 17 are cooperating with circumferential Latching means 20, 21 provided in the illustrated Embodiment designed as circumferential snap beads are. Another training could e.g. a screw locking connection can be provided. This Locking means 20, 21 are used to ensure that the cap-shaped closure element 17 initially in a first touchdown position can be placed on the sleeve-shaped element 10 (Fig. 3) and only after driving over the locking means 21 via the locking means 20 a complete tight Placing the cap-shaped closure element 17 on the sleeve-shaped element 10 takes place.

Vor der Befüllung der Nachfüllpatrone 1 ist diese im Bodenbereich vorzugsweise zweifach verschlossen, nämlich einmal mittels der Durchdrückstelle bzw. Dünnstelle 22 und einer Schutzfolie 23 oder dergl., die die Gewindebohrung 13 des Kolbens 12 verschließt. Before the refill cartridge 1 is filled, it is in the bottom area preferably closed twice, namely once by means of the push-through point or thin point 22 and one Protective film 23 or the like., Which the threaded bore 13 of the Piston 12 closes.

Nach dem Einsetzen des Kolbens 12 in das hülsenförmige Element 10 wird Klebstoffproduktmasse 15 in flüssiger Form in das hülsenförmige Element 10 eingefüllt, bis das hülsenförmige Element 10 weitgehend voll ist. Dabei wird durch die Schutzfolie 23 im Bereich der Gewindebohrung 13 verhindert, daß die Gewindebohrung 13 vollständig mit Klebstoffmasse ausgefüllt ist und verstopft.After inserting the piston 12 into the sleeve-shaped element 10 becomes adhesive product mass 15 in liquid form filled the sleeve-shaped element 10 until the sleeve-shaped Element 10 is largely full. It is by the Protective film 23 in the area of the threaded bore 13 prevents that the threaded bore 13 completely with adhesive is filled and clogged.

Im noch flüssigen Zustand der Klebstoffmasse 15 wird anschließend gemäß Fig. 3 das kappenförmige Verschlußelement 17 von oben auf das hülsenförmige Element 10 der Nachfüllpatrone derart aufgesetzt, daß die Rastmittel 20, 21 ohne Überfahren zur Anlage kommen, derart, daß der abdichtende Seitenwandbereich 17a des kappenförmigen Verschlußelementes 17 die Nachfüllpatrone 1 nach oben noch nicht dicht abschließt. Dabei dringt der stiftartige Ansatz 18 des kappenförmigen Verschlußelements 17 zentral in die flüssige Produktmasse 15 ein und bildet quasi als Kern die gewünschte durchgehende Bohrung 16 in der Produktmasse 15 aus. Durch geeignete Wahl der Länge des stiftartigen Ansatzes 18 dringt dabei das freie Ende 19 des stiftartigen Ansatzes bereits leicht in die Gewindebohrung 13 ein und wird in dieser zentriert.The adhesive composition 15 is then in the still liquid state 3, the cap-shaped closure element 17 from above onto the sleeve-shaped element 10 of the refill cartridge placed so that the locking means 20, 21 without Run over to the system in such a way that the sealing Sidewall region 17a of the cap-shaped closure element 17 does not yet seal the refill cartridge 1 tightly upwards. The pen-like approach 18 of the cap-shaped penetrates Closure element 17 centrally in the liquid Product mass 15 and forms the desired core through bore 16 in the product mass 15 out. By a suitable choice of the length of the pin-like approach 18 penetrates the free end 19 of the pin-like Approach already in the threaded bore 13 and is centered in this.

Sobald die Produktmasse 15 ausreichend erhärtet ist, wird das kappenförmige Verschlußelement 17 durch Überfahren der Rastmittel 20 über die Rastmittel 21 vollständig geschlossen, wodurch zum einen ein dichter Abschluß des oberen Endes der Nachfüllpatrone 1 gewährleistet ist, da die Rastmittel 20, 21 dicht aneinander anliegen und zum anderen der stiftartige Ansatz 18 mit seinem freien Ende 19 so weit in die Gewindebohrung 13 eindringt, daß dort befindliche Klebstoffreste beiseite geschoben werden.As soon as the product mass 15 has hardened sufficiently, is the cap-shaped closure element 17 by driving over the Locking means 20 completely closed via the locking means 21, on the one hand a tight seal of the upper end the refill cartridge 1 is guaranteed because the locking means 20, 21 lie close together and the other pin-like approach 18 with its free end 19 as far in the threaded hole 13 penetrates that there is adhesive residue be pushed aside.

Die Nachfüllpatrone 1 ist somit unter Ausbildung der durchgehenden Bohrung 16 in der Produktmasse 15 gebrauchsfertig und kann in dieser Form in den Handel gebracht werden.The refill cartridge 1 is thus with the formation of the continuous Hole 16 in the product mass 15 ready for use and can be marketed in this form.

Wird nun gemäß Fig. 1 die Nachfüllpatrone 1 als Bestandteil eines Klebestiftes 2 mit diesem in Verbindung gebracht, so wird das kappenförmige Verschlußelement 17 entfernt, und das hülsenförmige Verschlußelement 10 der Nachfüllpatrone 1 auf das Hülsenelement 3 des Klebestiftes 2 aufgeschraubt, wobei gleichzeitig die Gewindespindel 7 des Klebstiftes 2 nach Durchdringung der Dünnstelle 22 und der Schutzfolie 23 in die Gewindebohrung 13 des Kolbens 12 der Nachfüllpatrone 1 eingreift und die Produktmasse 15 die Bohrung 16 ohne Schwierigkeiten durchdringen kann.1 is the refill cartridge 1 as a component an adhesive stick 2 associated with this, so the cap-shaped closure element 17 is removed, and the sleeve-shaped closure element 10 of the refill cartridge 1 screwed onto the sleeve element 3 of the glue stick 2, the threaded spindle 7 of the glue stick 2 after penetration of the thin area 22 and the protective film 23 into the threaded bore 13 of the piston 12 of the refill cartridge 1 engages and the product mass 15 without the bore 16 Difficulties can penetrate.

Anschließend kann dann auf das hülsenförmige Element 10 bzw. auf dessen oberes Ende eine Verschlußkappe aufgebracht werden, um das hülsenförmige Element 10 abzudichten. Subsequently, the sleeve-shaped element 10 can then or applied a closure cap to its upper end to seal the sleeve-shaped member 10.

Dabei kann bei einer besonderen Ausbildung des kappenförmigen Verschlußelementes 17 dieses selbst als Verschlußkappe verwendet werden, wenn nämlich, wie dies Fig. 5 zeigt, das kappenförmige Verschlußelement 17 und der stiftartige Ansatz 18 zweiteilig lösbar miteinander verbindbar ausgebildet sind. Dazu weist, wie Fig. 5 zeigt, das kappenförmige Verschlußelement 17 im Inneren zentral einen zylindrischen Ansatz 24 mit umlaufender Rastwulst 25 auf, auf welche der stiftartige Ansatz 18, der innen hohl ausgebildet ist, mit einer korrespondierenden Innenwulst 26 aufsetzbar ist. Wird nun der stiftartige Ansatz 18 vom kappenförmigen Verschlußelement 17 entfernt, so kann das kappenförmige Verschlußelement 17 als Verschlußkappe für den Klebestift 2 verwendet werden.It can with a special training of the cap-shaped Closure element 17 itself as a closure cap can be used if, as shown in FIG. 5, the cap-shaped closure element 17 and the pin-like approach 18 formed in two parts releasably interconnectable are. 5 shows the cap-shaped Closure element 17 inside a cylindrical central Approach 24 with circumferential locking bead 25 on which the pin-like approach 18 which is hollow on the inside with a corresponding inner bead 26 can be placed. Becomes now the pin-like approach 18 from the cap-shaped closure element 17 removed, so the cap-shaped closure element 17 used as a sealing cap for the glue stick 2 will.

Bevorzugt besteht das kappenförmige Verschlußelement 17 aus einem flexiblen Kunststoffmaterial, während der stiftartige Ansatz 18 hart ausgebildet ist, wodurch eine gute Abdichtung des hülsenförmigen Elementes 10 durch das kappenförmige Verschlußelement 17 und eine einwandfreie Ausbildung der Bohrung 16 in der Produktmasse 15 durch den stiftartigen Ansatz 18 gewährleistet ist.The cap-shaped closure element 17 preferably consists of a flexible plastic material, while the pen-like Approach 18 is hard, creating a good seal of the sleeve-shaped element 10 by the cap-shaped Closure element 17 and proper training of Bore 16 in the product mass 15 through the pin-like Approach 18 is guaranteed.

Je nach den verwendeten Produktmassen kann das freie Ende 19 des stiftartigen Ansatzes 18 des kappenförmigen Verschlußelementes 17 eine unterschiedliche Gestaltung aufweisen. Bei den Ausführungsformen gemäß Fig. 2 bis 5 ist das freie Ende 19 spitz zulaufend ausgebildet, während bei der Ausgestaltung gemäß Fig. 6 das freie Ende 19a konisch und bei der Ausgestaltung nach Fig. 7 das freie Ende 19b stufenförmig ausgebildet ist.Depending on the product mass used, the free end can 19 of the pin-like extension 18 of the cap-shaped closure element 17 have a different design. In the embodiments according to FIGS. 2 to 5, this is free end 19 tapered, while at the 6, the free end 19a conical and 7, the free end 19b is stepped is trained.
