Description
Stift, insbesondere für Kosmetikzwecke,und VerfahrenPen, in particular for cosmetic purposes, and methods
zu seiner Herstellung.for its manufacture.
Die Erfindung betrifft einen Stift, bei dem eine vorgefertigte Mine von einer Ummantelung (Schaft) fest umschlossen ist, die aus einem spanabhebend bearbeitbaren (spitzbaren) Werkstoff besteht, sowie ein Verfahren zur Herstellung eines solchen Stiftes.The invention relates to a pen in which a prefabricated lead is firmly enclosed by a sheath (shaft), which consists of a cutting machinable (sharpenable) material consists, as well as a method for production such a pen.
Die Stiftummantelung hat den Zweck, die Mine abzustützen und gegen Bruch zu schützen. Durch die Ummantelung der vielfach verhältnismäßig dünn ausgebildeten Mine wird auch die Handhabung des Stifts erleichtert. Im allgemeinen besteht die Ummantelung aus Iiolz dder Kunststoff.The purpose of the pen casing is to support the mine and against it Protect breakage. Due to the sheathing of the often relatively thin Mine also makes the pen easier to use. In general, the Sheath made of Iiolz the plastic.
Es gibt Minen, die in besonderem Maße spröde sind und deshalb leicht brechen. Dies gilt z.B. für Minen mit einer kreideähnlichen Textur. Solche Minen werden vielfach für Pastellkreiden oder für kosmetische Zwecke als Puderkreiden verwendet. Damit sich derartige Minen auf der Schreibunterlage bzw. der Haut (pudrig) weich abstreichen lassen und dabei das in ihnen enthaltene Pigment in ausreichender Menge abgeben' wird ein möglichst geringer,Gehalt an Bindemittel angestrebt. Dies wirkt sich naturgemäß auf die Bruchfestigkeit der Mine negativ aus. Ein Anspitzen solcher Minen ist im allgemeinen nicht möglich, was ihren Gebrauchswert mindert, vor allem bei ihrer Verwendung in Stiften für kosmetische Zwecke.There are mines that are particularly brittle and therefore light break. This applies, for example, to mines with a chalk-like texture. Such mines are often used for pastel chalks or for cosmetic purposes as powder chalks used. So that such leads can be found on the writing pad or the skin (powdery) let it wipe off softly and the pigment contained in them in sufficient quantities The aim is to have as low a content of binder as possible. this naturally has a negative effect on the breaking strength of the lead. A sharpening such mines is generally not possible, which reduces their utility value, especially when used in pencils for cosmetic purposes.
Um für die ungenügende Bruchfesti*,keit einen Ausgleich zu schaffen, hat man die Minen mit einer Papierumwicklung versehen oder in eine sog. Schiebehülse eingebracht. Mit der Papierumwicklung wird die Festigkeit jedoch nur geringfügig verbessert. Die Entfernung des Papiers ist oft umständlich und schwierig und rührt vielfach zum Bröckeln der Mine.In order to compensate for the insufficient breaking strength, if the leads have been wrapped in paper or in a so-called sliding sleeve brought in. However, with the paper wrapping, the strength becomes only marginal improved. The removal of the paper is often cumbersome and difficult, and moves often to the crumbling of the mine.
bestimmten Verwendungszweck der Stifte besonders abgestimmten Werkstoffe bzw. Werkstoffmischungen ohne weiteres, gegf.specific use of the pins specially matched materials or material mixtures without further ado, if necessary.
nach einigen Vorversuchen, aufzufinden.after some preliminary attempts to find.
Es wurde bereits erwähnt, daß der Erfindung besondere Bedeutung zukommt für solche Stifte, bei denen die Minenmasse sich ni.cht im Gießverfahren verarbeiten und folglich auch nicht in flüssiger Form in eine vorgefertigte Ummantelung einbringen läßt. Dies gilt vor allem für Minenmassen mit hohen Anteilen an anorganischen Substanzen. Eine solche Minenmasse,deren strukturbildender Bestandteil aus Glimmer besteht und bei welcher die vorliegende Erfindung mit besonderem Vorteil anwendbar ist, wird in der DE-AS 25 40 877 beschrieben. In solchen Fällen wird die Fiinenmasse durch Zugabe einer FlüssiCkeit, vorzugsweise Wasser, in eine elastische Konsistenz und hiernach durch (Kalt)extrusion in die gewünschte Form gebracht, wonach dann die Flüssigkeit z.B. durch Abdampfen entfernt und auf diese Weise die Mine verfestigt wird. Es ergibt sich so eine Mine mit einer porösen Struktur, die der Mine die Eigenschaft verleiht, sich auf eine Unterlage weich abstreichen zu lassen, was vor allem für Kosmetikstifte erwünscht ist.It has already been mentioned that the invention is of particular importance for pencils where the lead mass cannot be processed in the casting process and consequently do not introduce it into a prefabricated casing in liquid form leaves. This is especially true for mine masses with high proportions of inorganic substances. Such a mine mass, the structure-forming component of which consists of mica and in which the present invention can be used with particular advantage in DE-AS 25 40 877 described. In such cases, the film mass is through Adding a liquid, preferably water, to an elastic consistency and then brought into the desired shape by (cold) extrusion, after which the Liquid removed e.g. by evaporation and in this way the mine solidified will. The result is a mine with a porous structure that gives the mine its property gives to be wiped softly on a surface, which is especially for Cosmetic pencils is desirable.
Wenn im Zusammenhang mit der Erfindung davon die Rede ist, daß die Ummantelung um die (vorgefertigte) Mine herumgegossen wird, dann sollen hiermit sämtliche Verfahren eingeschlossen werden, bei. denen eine flüssige Masse in eir.e offene oder geschlossene Form mit oder ohne Druck eingebracht und in der Form durch Erstarrung verfestigt wird. Somit kann bei der Ummantelung des erfindungsgemäßen Stiftes auch ein Spritzgußverfahren Anwendung finden.If in connection with the invention it is mentioned that the Sheathing is poured around the (prefabricated) mine, then this should be used all procedures are included. which a liquid mass in eir.e Open or closed form with or without pressure introduced and in the form Solidification is solidified. Thus, when sheathing the invention An injection molding process can also be used for the pin.
Bei der Herstellung des erfindungsgemäßen Stiftes kann in der Weise verfahren werden, daß ein vorgefertigtes (festes) Minenstiick in solcher Weise in einer Gießform angeordnet wird, daß um das Minenst@ @ herum ein @@@@@@@@ @@@@@ @@, desses Weite der Dicke der herzustellenden Ummantelung entspricht. In diesen Ringraum wird dann die gießbare Ummantelungsmasse eine bracht. Nach ihrer Erstarrung kann dann der Gießling der Form entnommen werden. Der Gießling kann entweder von vornherein in einer der Stiftgröße entsprechenden oder aber auch in einer größeren Länge hergestellt werden. Im letzteren Falle werden dann von dem Gießling der Stiftgröße entsprechende kürzere Stücke abgeschnitten. Der der Form entnommene Gießling bzw. die von diesem abgelängten Stücke werden anschließend an einem Ende angespitzt, wonach der fertige stift vorliegt.In the manufacture of the pen according to the invention can be in the manner be proceeded that a prefabricated (solid) mine piece in such a way in a casting mold is arranged that around the mine @ @ a @@@@@@@@ @@@@@ @@, whose width corresponds to the thickness of the casing to be produced. In this annulus then the castable coating compound is brought. After their solidification can then the casting can be removed from the mold. The casting can either from the outset in one corresponding to the pen size or also made in a longer length will. In the latter case, the pen size is then made from the casting cut off shorter pieces. The casting removed from the mold or that of it Cut to length pieces are then sharpened at one end, after which the finished pen is present.
In der Zeichnung ist die Herstellung des erfindungsgemäßen Stiftes an einem Ausführungsbeispiel veranschaulicht. Es zeigen: Figur 1 einen Läncsschnitt durch die mit einer vorgefertigten Mine bestückte Gießform; Figur 2 einen Längsschnitt durch den der Form entnommenen Gießling und Figur 3 eine Ansicht von dem fertigen Stift.The drawing shows the manufacture of the pen according to the invention illustrated in one embodiment. They show: FIG. 1 a longitudinal section through the casting mold equipped with a prefabricated lead; Figure 2 is a longitudinal section through the casting removed from the mold and FIG. 3 a view of the finished Pen.
In die mit 1 bezeichnete Gießform wird ein vorgefertigtes Minenstück 2 eingebracht und in dem Gießraum vermittels einer Zentrier-und Fixiereinrichtung 3 in solcher Weise angeordnet, daß um das Minenstück herum ein Ringraum 4 verbleibt. Zum Zwecke der Zentrierung des Minenstückes in der Form ist der Boden der Gießform mit einer dem Querschnitt des Minenstückes entsprechenden Ausnehmung 5 versehen, in welche das untere Ende des Minenstückes eingeführt wird. In den Ringraum 4 wird aus einem Behälter (, die Gießmasse 7 bis auf ein dem oberen Rand des Gießraumes entsprechendes Niveau eingefüllt.A prefabricated piece of lead is placed in the casting mold designated by 1 2 introduced and in the casting chamber by means of a centering and fixing device 3 arranged in such a way that an annular space 4 remains around the mine piece. For the purpose of centering the lead piece in the mold, the bottom of the casting mold is used provided with a recess 5 corresponding to the cross section of the lead piece, into which the lower end of the lead is inserted. In the annulus 4 is from a container (, the casting compound 7 except for the upper edge of the casting space corresponding level filled.
Nach der Verfestigung der Gießmasse,beispielsweise durch Abkühlung oder Aushärtung, kann der aus der Mine 2 und der UmmantelunF 7a bestehende fertige Gießling der Form entnommen werden. Hiernach wird dann das untere Ende des Gießlings in solcher Weise angespitzt, daß das Gebrauchsende des Stiftes eine konische Snitze e erhält, wobei die Minensoitze 2a aus der Ummantelun herausragt (Figur T).After the casting compound has solidified, for example by cooling or hardening, the finished product consisting of the lead 2 and the casing 7a can be used Casting can be removed from the mold. This is then followed by the lower end of the casting Sharpened in such a way that the working end of the pencil has a conical point e obtained, the mine sole 2a protruding from the Ummantelun (Figure T).
