Definitions
- the outer sleeve, the holding device and the foot part with rotating spindle are manufactured separately and then assembled.
- the rotating spindle must be quick and very precise for assembly rotated through a central recess in the holding device that was previously inserted into the outer sleeve, while at the same time the outer sleeve with its lower edge on Foot part snaps into place.
- the object of the invention was therefore to solve this assembly problem to solve.
- the solution principle according to the invention consists in the outer sleeve and the holding device in the form of a piston form as a one-piece injection molding, the piston is firmly connected to the sleeve wall via predetermined breaking points.
- the inventive method for producing a Adhesive stick with a rotating spindle and thus firmly connected foot part, supporting the pin mass Piston and a sleeve surrounding the pin mass with a cap closure is characterized in that the sleeve together with the piston forms a one-piece injection molding, the Piston is connected to the sleeve wall via predetermined breaking points, that the foot part with a rotating spindle arranged by a center Recess in the piston up to the stop of the lower edge of the sleeve is pushed through with the upper part of the foot part, that the pin mass in the unit thus formed from the sleeve and Foot part is cast with rotating spindle and after completion of the filling process actuated the rotatable foot section and thereby the Piston using the rotating spindle, tearing off the predetermined breaking points is lifted into the intended end position, the Support plate of the piston by means of edge notches provided on it or grooves on provided on the inside of the sleeve wall Guide webs is pushed
- the injection molding which forms the sleeve with the piston, can very conveniently be made from polypropylene.
- the foot part with the rotating spindle from the same Plastic like the sleeve or a compatible plastic is simplified by the present Invention not only the assembly as such (the piston is firmly anchored in the sleeve and the screwing in of the rotating spindle can be done without damaging the sealing elements, such as sealing lip of the spindle and sealing surface of the sleeve), but instead the disposal of waste and rejects is also made easier.
- the piston (1) is preferably in the form of a basket the threaded cam (5A) on its inner wall and preferably also on the outer wall of the central recess Has thread cams (5B).
- the centered recess in the piston (1) from at least two elastic ones facing each other Tongues (6) formed, which simultaneously engage the rotating spindle (7A).
- Fig. 1 By the reference numeral (8) in Fig. 1 is the locking mechanism between the lower end of the sleeve (2) and the Foot part (7) reproduced, whereby a complete unit is formed that is ready to receive the pen mass.
- the piston (1) can of course be designed in a different way, for. B. as a plate with anchoring plate arranged on it or as a nut only with Thread cams on the inner wall. It just has to take care of it that the filled pen mass after solidification slightly turned back and forth together with the piston can be attached without sticking to the inner wall of the sleeve stay d. H. the adhesive force of rest must be overcome.
- the plate When designing the piston as a plate with anchoring elements the plate must have recesses and one underneath have free space so that the pin mass up extends to the upper support plate and thereby itself for anchoring contributes.

- Verfahren zum Herstellen eines Klebstifts mit drehbarem, eine Drehspindel aufweisenden und damit fest verbundenem Fußteil, einem die Stiftmasse abstützenden Kolben und einer die Stiftmasse umgebenden Hülse mit Kappenverschluß, dadurch gekennzeichnet, daß die Hülse zusammen mit dem Kolben einen einteiligen Spritzformling bildet, wobei der Kolben über Sollbruchstellen mit der Hülsenwand verbunden ist, daß der Fußteil mit Drehspindel durch eine zentriert angeordnete Ausnehmung im Kolben bis zum Anschlag des unteren Hülsenrandes mit dem oberen Teil des Fußteils hindurchgeschoben wird, daß die Stiftmasse in die so gebildete Einheit aus Hülse und Fußteil mit Drehspindel eingegossen wird und nach Beendigung des Füllvorganges das drehbare Fußteil betätigt und dadurch der Kolben mittels des Stütztellers der Drehspindel unter Abreißen der Sollbruchstellen in die vorgesehene Endlage gehoben wird, wobei der Stützteller des Kolbens mittels an ihm vorgesehenen Randkerben oder -nuten auf an der Innenseite der Hülsenwand vorgesehene Führungsstege geschoben wird, worauf der Kappenverschluß auf die mit Klebstoff gefüllte Hülse aufgesetzt wird.
- Anordnung zum Durchführen des Verfahrens nach Anspruch 1, bestehend aus(a) einem drehbaren Fußteil (7), welches über ein Drehelement (7B) fest mit einer Drehspindel (7A) verbunden ist und eine dem freien Durchmesser der Hülse (2) entsprechende, im Abstand voneinander angeordnete Stützteller (9A, 9B) aufweist,(b) einem beidseitig offenen Hülsenteil (2) mit darin über Sollbruchstellen (3) fest verbundenem Kolben (1), der Verankerungs-und Stützelemente für die Stiftmasse aufweist, wobei der Kolben mit einer zentriert angeordneten Ausnehmung versehen ist und am äußeren Rand Stützflügel (11) aufweist, während an der Innenwand des Hülsenteils (2) in Längsrichtung Führungsstege (12) vorgesehen sind.
- Anordnung nach Anspruch 2, dadurch gekennzeichnet, daß der Kolben (1) in Form eines Körbchens ausgebildet ist, das an seiner Innenwand Gewindenocken (5A) und vorzugsweise auch an der Außenwand der zentralen Ausnehmung Gewindenocken (5B) aufweist.
- Anordnung nach Anspruch 2 und/oder 3, dadurch gekennzeichnet, daß die zentriert angeordnete Ausnehmung im Kolben (1) aus mindestens zwei elastischen, sich gegenüberliegenden Zungen (6) gebildet wird, die gleichzeitig den Eingriff in die Drehspindel (7A) bilden.
- Anordnung nach irgendeinem der Ansprüche 2 bis 4, dadurch gekennzeichnet, daß zwischen der Innenwand der Hülse (2) und dem Teil (7, 7A, 7B) in der Einfüllstellung mindestens ein Luftkanal (4) vorhanden ist, der nach Erreichen der Endlage (10) des Teils (7, 7A, 7B) keine Verbindung mehr zu dem mit der Stiftmasse gefüllten Raum hat.
