The sheath is entirely or mainly made from papier-mâché, sawdust and/or wood shavings. The invention also concerns processes for manufacturing crayons of this type, in particular by casting or injection moulding, using compressive or extrusion techniques.

Description

Schreib- oder Malstift und Verfahren zu dessen Herstellung Writing or drawing pen and process for its manufacture

Beschreibungdescription

Die Erfindung betrifft einen Schreib- oder Malstift mit einer Umhüllung und einer hierin angeordneten Mine sowie ggf. weite¬ ren Elementen und Verfahren zu dessen Herstellung.The invention relates to a writing or drawing pen with a covering and a lead arranged therein, and optionally further elements and methods for its production.

Schreib- oder Malstifte weisen üblicherweise eine Umhüllung aus Holz oder aus Kunststoff auf. Bei fest mit der Umhüllung ver¬ bundenen Stiften sind auch geschäumte Kunststoffschäfte bekannt, die im Extrusions- oder im Co-Extrusionsverfahren her¬ gestellt werden. Holzgefaßte Stifte werden dagegen in der Regel aus genuteten Brettchen gefertigt, während lose oder fest mit der Mine verbundene Umhüllungen aus Kunststoff meist im Spritz¬ gießverfahren erzeugt werden.Pens or crayons usually have an envelope made of wood or plastic. In the case of pins firmly connected to the sheath, foamed plastic shafts are also known which are produced in the extrusion or in the co-extrusion process. Wood-cased pencils, on the other hand, are generally made from grooved boards, while loose or rigid plastic envelopes are usually produced using the injection molding process.

Nachteilig ist bei allen bekannten, bzw. derzeit erhältlichen Umhüllungen, daß sie aus hochwertigen Naturprodukten, wie Holz •oder Rohöl-Derivaten bestehen und damit deren Verbrauch erhöhen und daß sie zum anderen - soweit sie aus Kunststoffen herge¬ stellt sind - meist nur unter gewisser Belastung der Umwelt "entsorgt" werden können.It is a disadvantage of all known or currently available casings that they consist of high-quality natural products such as wood or crude oil derivatives and thus increase their consumption, and that they - to the extent that they are made of plastics - usually only to a certain extent Environmental pollution can be "disposed of".

Obwohl bereits um die Jahrhundertwende empfohlen wurde, Blei¬ stifte mit Papier- und Papiermasse- oder Kunstholzumhüllungen zu versehen, ist offensichtlich bis heute kein derartiger pro¬ duzierter Stift bekanntgeworden. Ebenso konnte sich wohl auch kein Herstellungsverfahren hierfür durchsetzen. Unter diesem Aspekt sind auch die beispielsweise aus DE- PS 473 641, DE-PS 496 016. DE-PS 496 017 und DE AS 14 71 373 bekannten Stifte und Verfahren zu sehen, die allesamt offen¬ sichtlich zu keinem akzeptablen bzw. brauchbaren Produkt oder Herstellungsverfahren führten, da heute kein eipziger derarti¬ ger Artikel erhältlich ist. Aufgabe der vorliegenden Erfindung ist es daher, eine Umhüllung für Schreib- oder Malstifte zu schaffen und geeignete Verfahren zu deren Herstellung vorzuschlagen, die insbesondere nicht aus Naturholz oder aus (thermoplastischen) Kunststoffen bestehen, und die einfach und zeitgemäß, unter bevorzugter Verwendung vorhandener Abfall- oder Recycling-Materialien, herstellbar sind.Although it was already recommended at the turn of the century to provide pencils with paper and paper pulp or synthetic wood coverings, no such pen produced has apparently become known to date. Likewise, no manufacturing process for this could also prevail. The pens and processes known from DE-PS 473 641, DE-PS 496 016, DE-PS 496 017 and DE AS 14 71 373, for example, are all to be seen from this aspect, all of which obviously do not result in an acceptable or usable product or manufacturing processes, since no eipzig such article is available today. It is therefore an object of the present invention to provide a covering for pens or crayons and to propose suitable processes for their production, which in particular do not consist of natural wood or (thermoplastic) plastics and which are simple and contemporary, with the preferred use of existing waste. or recycled materials can be produced.

Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruchs 1 auf einfache Weise gelöst.This object is achieved in a simple manner with the characterizing features of claim 1.

Bevorzugte Ausführungen und Weiterbildungen sind in den Unter- und Nebenansprüchen umfaßt.Preferred embodiments and further developments are included in the subordinate and additional claims.

Anhand einiger Ausführungsbeispiele wird die Erfindung nach¬ folgend näher beschrieben.The invention is described in more detail below with the aid of a few exemplary embodiments.

Erfindungsgemäß soll die Umhüllung eines Schreib- oder Malstif¬ tes, dessen Mine fest in die Umhüllung eingeleimt oder in die¬ ser axial, insbesondere mittels einer schiebe-, Dreh- oder Druckmechanik, verstellbar angeordnet ist, ganz oder überwie¬ gend aus Holzmehl, Holzschliff und/oder Papier- bzw. Pappmache bestehen.According to the invention, the casing of a writing or painting pen, the lead of which is firmly glued into the casing or is arranged such that it can be adjusted axially, in particular by means of a sliding, rotating or pressing mechanism, entirely or predominantly of wood flour, ground wood and / or paper or paper mache.

Unter Holzmehl ist hierbei sehr fein zerkleinertes Holz, bei¬ spielsweise auch Sägemehl, zu verstehen, das vielfach als Abfallprodukt bei der Holzverarbeitung anfällt.Wood flour is understood to mean very finely chopped wood, for example also sawdust, which is often obtained as a waste product in wood processing.

Holzschliff - auch Pulpe genannt - besteht aus i.d.R. unter 0,2 mm großen Holzfasern, die unter Wasserzugabe von (meist Fichten-) Holzstücken mittels großer grober Schleifsteine "abgeschliffen" werden.Wood pulp - also called pulp - usually consists of under 0.2 mm wood fibers, which are "sanded" with the addition of water (mostly spruce) pieces of wood using large coarse grindstones.

Ohne weitere Behandlung stellt diese Pulpe das Rohprodukt für minderwertige Papierprodukte dar und ist u. a. auch als Holz¬ pappe im Handel erhältlich. Papier- bzw. Pappmache ist i.d.R. eine aus Altpapier, Holz¬ oder Strohstoff, Ton, Gips, Kieselgur, Leim oder Stärke hergestellte plastische Masse, die beispielsweise nach Durchtränkung mit heißem Leinöl und/oder einer Zinkchloridlösung in geölte Formen gepreßt werden kann.Without further treatment, this pulp is the raw product for inferior paper products and is also commercially available as wooden cardboard. Paper or paper mache is usually a plastic mass made from waste paper, wood or straw, clay, plaster, diatomaceous earth, glue or starch, which can be pressed into oiled molds after soaking with hot linseed oil and / or a zinc chloride solution.

Zur eventuellen Erhöhung der Festigkeit und der Stabilität der Umhüllung kann der Grundmasse vorteilhafterweise, je nach Bedarf, Holz- oder Knochenleim, vorzugsweise ein Dispersionskleber zugegeben werden.In order to possibly increase the strength and stability of the covering, wood or bone glue, preferably a dispersion adhesive, can advantageously be added to the base mass, as required.

Ebenso können Zusätze von Füllstoffen und/oder von Treibmitteln die Stabilität, das Gewicht und die Spitzbarkeit besonders positiv beeinflussen.Additions of fillers and / or propellants can also have a particularly positive effect on stability, weight and sharpenability.

Bei erfindungsgemäßen üblichen Blei- und Farbstiften sind die Minen mit der Umhüllung fest verbunden, insbesondere verleimt und gut spitzbar.In conventional lead and colored pencils according to the invention, the leads are firmly connected to the casing, in particular glued and easy to sharpen.

Dienen die erfindungsgemäßen Umhüllungen als Schäfte für Schiebe-, Dreh- oder Druckstifte, so sind die Minen hierin, i. d. R. durch mechanische Betätigung eines Vorschubelementes, axial verschieb- bzw. verstellbar.If the casings according to the invention serve as shafts for pushing, turning or pushing pins, the leads here, i. d. R. by mechanical actuation of a feed element, axially displaceable or adjustable.

Die Herstellung erfindungsgemäßer Stifte kann überraschender¬ weise meist mit den gleichen Herstellungsverfahren und vielfach auch mit den gleichen Anlagen und Vorrichtungen erfolgen, wie sie derzeit bei der Produktion üblicher Holz- oder Kunststoff¬ stifte verwendet werden.Surprisingly, pens according to the invention can usually be produced using the same production processes and in many cases also using the same systems and devices as are currently used in the production of conventional wooden or plastic pens.

So ist es möglich, die Umhüllungen bzw. Schäfte in Formen im Form- bzw. Spritzgießverfahren herzustellen und hierbei die - ggf. vorgefertigten - Minen entweder gleich mit einzuspritzen oder nachträglich einzusetzen. Andererseits können die Umhüllungen aber auch im Extrusions- oder im Strangpreßverfahren vorteilhaft gefertigt werden, ins¬ besondere auch im Co-Extrusions- oder im Duo-Strangpreßverfah¬ ren jeweils gleich kontinuierlich oder diskontinuierlich zusam¬ men mit der Mine.It is thus possible to manufacture the sheaths or shafts in molds using the molding or injection molding process, and in this case either to inject the - possibly prefabricated - mines at the same time or to insert them subsequently. On the other hand, the envelopes can also advantageously be produced in the extrusion or extrusion process, in particular also in the co-extrusion or in the duo extrusion process, in each case in the same way continuously or discontinuously together with the lead.

Wird demgegenüber die Grundmasse der Umhüllungen zunächst mit¬ tels Formpress-, Strangpress- oder Extrusions erfahren zu "üblichen Bleistiftbrettchen" - ungenutet oder bereits vorgenutet - verarbeitet, so kann die weitere Fertigung im wesentlichen in gleicher Weise erfolgen wie bisher. Das heißt, die "Brettchen" werden als Halbschalen für mehrere Stifte, ggf. genutet, mit Leim bestrichen, mit Minen belegt, gegenseitig verleimt und getrennt, dann werden die einzelnen Stifte geschliffen, poliert, bzw. lackiert und angespitzt.If, on the other hand, the basic mass of the coverings is first processed by means of compression molding, extrusion molding or extrusion to give "customary pencil boards" - unslotted or already pre-grooved - further production can be carried out essentially in the same way as before. This means that the "boards" are half-shells for several pens, possibly grooved, coated with glue, coated with leads, mutually glued and separated, then the individual pens are ground, polished, or varnished and sharpened.

Unabhängig von der Art des Herstellungsverfahrens können die Umhüllungen, bzw. die Stifte generell, bzw. bedarfsweise zur endgültigen Fertigstellung am Umfang bzw. äußerlich geschliffen, poliert, lackiert sowie ggf. anderweitig mit einer glatten und/oder farbigen Oberfläche versehen werden.Regardless of the type of manufacturing process, the envelopes, or the pins in general, or if necessary for final completion on the circumference or externally ground, polished, varnished and, if necessary, otherwise provided with a smooth and / or colored surface.

Besonders vorteilhaft kann auch ein, ggf. schlauch- oder rohrförmig vorgefertigter Überzug aus Gummi, Kunststoff oder Papier, auf die Umhüllung aufgebracht werden.A coating of rubber, plastic or paper, which may be prefabricated in a tubular or tubular manner, can also be applied to the covering in a particularly advantageous manner.

Sofern die Zugabe eines Treibmittels vorgesehen ist, kann dies - je nach Art des Treibmittels - bereits bei der Herstellung der Grundmasse oder vorteilhaft im Verlauf des Formgebungsverfahrens, insbesondere während des Form- oder Strangpressens oder beim Extrudieren, erfolgen. In der Abbildung ist lediglich eine generelle Darstellungsform der Erfindung gezeigt, wobei die, als Schaft eines einfachen Blei- oder Farbstiftes gestaltete, e'rfiήdungsgemäße Umhüllung 1 eine Spitze 2 und eine Mine 3 aufweist.If the addition of a blowing agent is provided, this can - depending on the type of blowing agent - already take place during the production of the base material or advantageously during the course of the shaping process, in particular during the molding or extrusion or during extrusion. In the figure, only a general illustration of the invention is shown, wherein the, designed as a shaft of a simple lead or colored pencil, e 'rfiήdungsgemäße wrapper 1 comprises a tip 2 and a refill. 3

Die erfindungsgemäßen Umhüllungen können aber auch in beliebi¬ ger Modifikation als Schäfte für praktisch jede Art von Schreib- oder Zeichengeräten verwendet werden bzw. dienen. However, the envelopes according to the invention can also be used or serve in any modification as shafts for practically any type of writing or drawing devices.
