Description

Die Erfindung betrifft eine Schutzkappe, insbesondere für Schreibgeräte, aus einer länglichen, innen hohlen Hülse.The invention relates to a protective cap, in particular for writing utensils, made of an elongated, hollow sleeve.

Derartige Schutzkappen sollen das Austrocknen flüssiger Stoffe und ein Naßwerden feuchtigkeitsempfindlicher Stoffe verhindern und werden zu diesem Zweck vorzugsweise für Schreibstifte und Feuerwerkskörper verwendet. Sie dienen bei Schreibstiften zur Abdeckung der Miene oder der Feder um ein Austrocknen der Tintenflüssigkeit zu verhindern und um eine Verschmutzung von benachbarten Gegenständen zu vermeiden. Bei Feuerwerkskörpern dient die Schutzkappe insbesondere der Umhüllung der Lunte und deren Protektion.Such protective caps are intended to prevent the drying out of liquid substances and the getting wet of moisture-sensitive substances and are preferably used for this purpose for pens and fireworks. They are used for pens Cover the face or the spring to prevent the ink liquid from drying out and to prevent contamination of neighboring objects. In the case of fireworks, the protective cap serves in particular to wrap the fuse and protect it.

Die bekannten, gattungsgemäßen Schutzkappen sind aus Metall oder Kunststoffen hergestellt und können, nachdem sie nicht mehr benötigt werden, sehr schlecht oder gar nicht entsorgt werden.The known, generic protective caps are made of metal or plastics and, after they are no longer required, can be disposed of very poorly or not at all.

Der Erfindung liegt daher die Aufgabe zugrunde, eine leicht zu entsorgende Schutzkappe zu schaffen.The object of the invention is therefore to create an easy-to-dispose protective cap.

Diese Aufgabe wird durch die Erfindung dadurch gelöst, daß die Schutzkappe aus einem biologisch abbaubarem oder verrottbarem Material hergestellt ist.This object is achieved by the invention in that the protective cap is made from a biodegradable or rotten material.

Eine solche Schutzkappe hat den Vorteil, daß sie in einfacher Weise entsorgt werden kann, wenn sie nicht mehr benötigt wird. Wird die Schutzkappe auf einer Mülldeponie entsorgt, so bewirkt das biologisch abbaubare oder verrottbare Material einen schnellen Zerfall der Schutzkappe in seine Bestandteile. Außerdem kann unter Umständen das Material der Schutzkappe wiederverwertet werden.Such a protective cap has the advantage that it can be disposed of in a simple manner when it is no longer required. If the protective cap is disposed of in a landfill, the biodegradable or rotten material causes the protective cap to quickly disintegrate into its components. The material of the protective cap can also be recycled under certain circumstances.

Eine aus biologisch abbaubarem oder verrottbarem Material, wie zum Beispiel Papier, Pappe, Karton, Altpapier, Vliesstoff, Pappmaché, Zellstoffprodukte, verrottbare, organische Stoffe oder dergleichen hergestellte Schutzkappe kann in einfacher Weise wiederverwertet werden, analog zu den bekannten Verfahren der Papierwiederverwertung.A protective cap made from biodegradable or decomposable material, such as paper, cardboard, cardboard, waste paper, nonwoven, paper mache, pulp products, decomposable organic substances or the like, can be easily recycled, analogously to the known methods of paper recycling.

Eine aus Papier- oder Zellstoffprodukten hergestellte Schutzkappe kann vorteilhafterweise zum gewöhnlichen Altpapier gegeben werden und somit in einfacher Weise in den bereits existierenden Recycelkreislauf von Papier gegeben werden, was eine deutliche Entlastung des Müllberges zur Folge hätte und einen positiven Beitrag zum Unweltschutz darstellt.A protective cap made from paper or cellulose products can advantageously be added to ordinary waste paper and thus easily added to the already existing recycling cycle of paper, which would result in a significant relief of the waste mountain and make a positive contribution to environmental protection.

Als biologisch abbaubares oder verrottbares Material für die Schutzkappe ist insbesondere auch ein Gelatinematerial, oder ein aus pflanzlichen Rohstoffen, wie aus Mais, aus Kartoffeln oder anderen pflanzlichen Stärkelieferanten gewonnenes Stärkematerial, gegebenenfalls mit einer Beimengung von Zusatzstoffen, die aus der konventionellen Nahrungsmittelverpackung stammen, beispielsweise Polyethylen sowie ein aus Harnstoff bestehendes Material verwendbar.As a biodegradable or rotten material for the protective cap is in particular also a gelatin material or a starch material obtained from vegetable raw materials, such as from corn, from potatoes or other vegetable starch suppliers, optionally with an admixture of additives that come from the conventional food packaging, for example polyethylene and a material consisting of urea can be used.

Die Schutzkappe kann als längliche, innen hohle Hülse ausgeführt sein, die an beiden Seiten offen ist. Sie kann in einfacher Weise über ein Schreibgerät gestülpt werden um eine Verschmutzung benachbarter Gegenstände zu verhindern.The protective cap can be designed as an elongated, internally hollow sleeve that is open on both sides. It can easily be slipped over a writing instrument to prevent contamination of neighboring objects.

In einer bevorzugten Ausführungsform der Erfindung werden mehrere Papierbahnen unter Zugabe eines biologisch abbaubaren bzw. bei der Wiederverwertung abtrennbaren Bindestoffes zu einer Hülse gewickelt, die je nach Anwendungsbereich über unterschiedliche Wandstärken verfügt. Durch das Verkleben und Wickeln der Papierbahnen erhält die Schutzkappe eine hohe Formfestigkeit und ist somit sehr gut geeignet als Schutzkappe für Schreibgeräte.In a preferred embodiment of the invention, a plurality of paper webs are wound into a sleeve with the addition of a biodegradable binding material or one which can be separated during recycling, which has different wall thicknesses depending on the area of application. By gluing and wrapping the paper webs, the protective cap is given a high dimensional stability and is therefore very suitable as a protective cap for writing instruments.

In einer weiteren besonderen Ausführungsform der erfindungsgemäßen Schutzkappe wird diese aus Pappmaché gefertigt. Hierzu werden kleine Papierschnitzel oder Papierspäne mit einem Bindemittel vermengt und anschließend in die gewünschte Form gepreßt. Die Verwendung von Pappmaché mit organischem Bindemittel zur Herstellung von Schutzkappen hat den großen Vorteil, daß somit biologisch abbaubare und leicht verrottbare Schutzkappen entstehen.In a further special embodiment of the protective cap according to the invention, it is made of paper mache. For this purpose, small pieces of paper or shavings are mixed with a binder and then pressed into the desired shape. The use of paper mache with organic binders for the production of protective caps has the great advantage that biodegradable and easily rotable protective caps are created.

In einer weiteren Ausführungsform der erfindungsgemäßen Schutzkappe wird diese aus einem biologisch abbaubaren organischen Stoff derart gefertigt, daß sie mit entsprechendem Bindemittel in die gewünschte Form gespritzt wird. Die Verwendung eines derartigen Stoffes ermöglicht die Herstellung aller möglichen Formen von Schutzkappen und hat den großen Vorteil, daß biologisch abbaubare und leicht verrottbare Schutzkappen entstehen.In a further embodiment of the protective cap according to the invention, it is made from a biodegradable organic substance in such a way that it is injected into the desired shape with the appropriate binder. The use of such a substance enables the production of all possible forms of protective caps and has the great advantage that biodegradable and easily rotable protective caps are produced.

Derartige Schutzkappen werden vorzugsweise bei Feuerwerkskörpern eingesetzt und zwar um die Lunte vor Feuchtigkeit und Beschädigung zu schützen.Protective caps of this type are preferably used for fireworks, to protect the fuse from moisture and damage.

Feuerwerkskörper werden auf freiem Gelände gezündet und landen an einem nicht vorhersehbaren Ort, so daß ein Wegräumen der Überbleibsel fast unmöglich ist. Daher ist der Einsatz von biologisch abbaubaren oder verrottbaren Materialien für Feuerwerkskörper sehr vorteilhaft.Fireworks are ignited in open areas and land in an unpredictable place, so that clearing away the remains is almost impossible. Therefore, the use of biodegradable or rotten materials for fireworks is very beneficial.

In einer weiteren bevorzugten Ausführungsform wird die Hülse einseitig ganz oder zumindest teilweise geschlossen. Dies hat den Vorteil einer erhöhten Schutzwirkung und ist ohne großen Aufwand durch Umbördeln einer offenen Hülsenseite zu erreichen.In a further preferred embodiment, the sleeve is completely or at least partially closed on one side. This has the advantage of an increased protective effect and is without great To achieve effort by flanging an open sleeve side.

In einer weiteren, ebenfalls kostengünstig herzustellenden Ausführungsform ist ein Hülsenende verpreßt, daß heißt, noch während der Herstellung der Hülse wird dieses Hülsenende zusammengepreßt, so daß nach dem Austrocknen der Hülse eine einseitig luftdicht verschlossene Schutzkappe entsteht.In a further embodiment, which is also inexpensive to manufacture, a sleeve end is pressed, that is, this sleeve end is pressed together during the manufacture of the sleeve, so that a protective cap which is airtight on one side is formed after the sleeve has dried out.

In einer erfindungsgemäßen Weiterbildung der Schutzkappe wird die Hülse einseitig, bei einer einseitig teilweise geschlossenen Hülse eben diese Seite, mit einem Kümpel aus biologisch abbaubarem oder verrottbarem Material luftdicht verschlossen. Es ist auch möglich, die Hülse einseitig mit einem Verschluß aus Kunststoff oder einem anderen nicht biologisch abbaubarem oder verrottbarem Material zu verschließen. Hierbei wird der Kümpel, bzw. der Verschluß, von außen auf die Hülse aufgesetzt oder innen in die Hülse eingesetzt. Der Kümpel, bzw. der Verschluß, kann verschiedene Formen haben, je nach Einsatzgebiet der Schutzkappe. Der Verschluß oder der Kümpel kann zum Beispiel eine einfache Scheibe sein; er kann zylindrisch oder U-förmig sein, er kann einen halbkugelförmigen, zylindrischen oder kegelförmigen aus der Hülse hinausragenden Überhang haben, oder er kann bündig mit der Hülse abschließen. Eine derart einseitig verschlossene Schutzkappe hat den Vorteil, daß der Schutzgegenstand vor Austrocknung, Verschmutzung, Feuchtigkeit und Beschädigung optimal geschützt wird.In a further development of the protective cap according to the invention, the sleeve is hermetically sealed on one side, in the case of a sleeve which is partially closed on one side, with a dome made of biodegradable or rotten material. It is also possible to seal the sleeve on one side with a closure made of plastic or another non-biodegradable or rotten material. Here, the cumin, or the closure, is placed on the outside of the sleeve or inserted into the inside of the sleeve. The dome or the closure can have different shapes, depending on the area of application of the protective cap. For example, the breech or dome may be a simple disc; it can be cylindrical or U-shaped, it can have a hemispherical, cylindrical or conical overhang protruding from the sleeve, or it can be flush with the sleeve. Such a protective cap closed on one side has the advantage that the protective object is optimally protected from drying out, soiling, moisture and damage.

In speziellen Anwendungsgebieten ist es auch möglich, eine erfindungsgemäße Schutzkappe mit einem Halteklip auszustatten, damit ein mit einer erfindungsgemäßen Schutzkappe ausgerüsteter Stift auch in der Hemd- oder Jackettasche festgeklemmt werden kann.In special fields of application it is also possible to equip a protective cap according to the invention with a retaining clip so that a pin equipped with a protective cap according to the invention can also be clamped in the shirt or jacket pocket.

Die in Figur 1 dargestellte, innen hohle Hülse 1 ist erfindungsgemäß aus einem biologisch leicht abbaubarem oder verrottbarem Material hergestellt. Hierzu können beispielsweise Materialien, wie Pappe, Karton, Vliesstoff, Pappmaché oder Papier verwendet werden, wobei als Ausgangsmaterial Zellulose, Zellstoff und vorzugsweise Altpapier verwendet wird. Weitere Materialien, die leicht biologisch abbaubar oder verrottbar sind können aus Pflanzen, wie Kartoffeln, Mais etc. gewonnene Stärke gegebenenfalls mit einer Beimengung von aus der konventionellen Nahrungsmittelverpackungsindustrie stammenden Zusatzstoffen enthalten oder aus Harnstoff oder Gelatine bestehen.The inside hollow sleeve 1 shown in Figure 1 is made according to the invention from a readily biodegradable or rotten material. For this purpose, for example, materials such as cardboard, cardboard, nonwoven, paper mache or paper can be used, cellulose, cellulose and preferably waste paper being used as the starting material. Other materials that are easily biodegradable or rotable can contain starch obtained from plants, such as potatoes, corn, etc., optionally with an admixture of additives from the conventional food packaging industry, or consist of urea or gelatin.

Die Hülse 1 wird beim Ausführungsbeispiel aus Pappe aus mehreren miteinander verklebten Papierschichten gewickelt, sie kann aber auch aus Pappmaché oder verrottbarem Stoff gepreßt bzw. gegossen sein. Ein biologisch sehr leicht abbaubares oder verrottbares Pappmaché entsteht durch Verwendung von Altpapierspänen, die mit einem Bindemittel vermengt werden. Ein derart hergestelltes Pappmaché kann in flüssigem Zustand in einfacher Weise in jede beliebige Form gepreßt werden, so daß nach Erstarren des Pappmachés oder des verrottbaren, organischen Stoffs eine sehr leicht biologisch abbaubare oder verrottbare Schutzkappe zur Verfügung steht.In the exemplary embodiment, the sleeve 1 is wound from cardboard from several layers of paper glued to one another, but it can also be pressed or cast from paper mache or rotten material. A readily biodegradable or rotten paper mache is created by using waste paper chips that are mixed with a binder. A paper mache produced in this way can be easily pressed into any shape in the liquid state, so that after the paper mache or the rotten, organic substance has solidified, a very easily biodegradable or rotten protective cap is available.

Die Hülse 1 kann in verschiedenen Ausführungsformen gefertigt werden, wobei der Querschnitt rund, oval oder vieleckig sein kann und die Hülse 1 eine zylindrische, kegelige oder nach innen und außen abgesetzte Form haben kann.The sleeve 1 can be manufactured in various embodiments, wherein the cross section can be round, oval or polygonal and the sleeve 1 can have a cylindrical, conical or offset shape inwards and outwards.

In den Figuren 2a bis 2c sind Schutzkappen mit einseitig umgebördeltem Ende gezeigt. Das Ende kann hierbei nur ein wenig umgebördelt sein, wie Figur 2a zeigt, oder die Seite der Hülse 1 kann fast vollständig zugebördelt werden, wie Figur 2d zeigt. Es ist auch möglich, das Ende, im Querschnitt halbkreisförmig umzubördeln, wie Figur 2c zeigt.FIGS. 2a to 2c show protective caps with a flanged end on one side. The end can only be flanged a little, as shown in FIG. 2a, or the side of the sleeve 1 can be flanged almost completely, as shown in FIG. 2d. It is also possible to flare the end in a semicircular cross section, as shown in FIG. 2c.

In den Figuren 3a bis 3c sind weitere Ausführungsformen der erfindungsgemäßen Schutzkappe gezeigt, die einen Verschlußstopfen 2 aus einem Material haben, das nicht verrottbar oder biologisch abbaubar sein muß,wenn der Verschlußstopfen 2 nur formschlüssig eingesetzt und vor der Entsorgung abziehbar ist. Diese Verschlüsse 2 können bündig mit der Hülse 1 enden, wie in Figur 3c oder über das Hülsenende hinausstehen, wie in den Figuren 3a und 3b. Der über das Hülsenende hinausstehende Teil des Verschlusses 2 kann zylindrisch, kegelförmig, halbkugelförmig sein, oder eine beliebige andere Form annehmen.In Figures 3a to 3c further embodiments of the protective cap according to the invention are shown, which have a sealing plug 2 made of a material that does not have to be rot or biodegradable if the sealing plug 2 is only inserted in a form-fitting manner and can be removed before disposal. These closures 2 can end flush with the sleeve 1, as shown in FIG. 3c, or protrude beyond the sleeve end, as in FIGS. 3a and 3b. The part of the closure 2 projecting beyond the sleeve end can be cylindrical, conical, hemispherical, or can take any other shape.

In einer weiteren Ausgestaltungsform wird gemäß Fig. 4 eine innen hohle Hülse 3, deren Außendurchmesser dem Innendurchmesser der Schutzkappe entspricht, einseitig in die Schutzkappe eingesetzt, z. B. eingeklebt. Eine solcher Einsatz ist kürzer als die Hülse 1 und kann aus demselben Material wie die Hülse 1 bestehen.In a further embodiment, an internally hollow sleeve 3, the outer diameter of which corresponds to the inner diameter of the protective cap, is inserted on one side into the protective cap, for. B. glued. Such an insert is shorter than the sleeve 1 and can consist of the same material as the sleeve 1.

In den Figuren 5a bis 5e werden weitere Ausgestaltungen der erfindungsgemäßen Schutzkappe gezeigt, bei denen ein Kümpel 4 aus biologisch abbaubarem und verrottbarem Material an einem Ende der Hülse 1 angeordnet ist. Der Kümpel 4 verschließt dieses Ende der Schutzkappe luftdicht und kann innen in die Hülse 1 eingesetzt und verklebt werden, wie in den Figuren 5a und 5b oder von außen auf das Hülsenende aufgesetzt werden, wie Figur 5c zeigt. Ist die Hülse 1 an einer Seite umgebördelt, so wird der Kümpel 4 oder die Bodenscheibe 6 von innen in die Hülse 1 eingesetzt um das umgebördelte Ende der Hülse 1 luftdicht zu verschließen, wie in den Figuren 5d und 5e gezeigt.FIGS. 5a to 5e show further embodiments of the protective cap according to the invention, in which a dome 4 made of biodegradable and rotten material is arranged at one end of the sleeve 1. The cumin 4 closes this end of the protective cap airtight and can be inserted and glued inside the sleeve 1, as in FIGS. 5a and 5b or be placed on the end of the sleeve from the outside, as shown in FIG. 5c. If the sleeve 1 is flanged on one side, the cumin 4 or the base plate 6 is inserted into the sleeve 1 from the inside in order to seal the flanged end of the sleeve 1 airtight, as shown in FIGS. 5d and 5e.

Es ist auch möglich, wenn auch nur mit sehr hohem Aufwand, das Hülsenende luftlicht zuzubördeln, wie in Figur 6a gezeigt. Die in Figur 6b gezeigte Hülse 1 hat ein abgesetztes kegeliges Ende, welches ebenfalls luftdicht zugebördelt ist.It is also possible, if only with a great deal of effort, to crimp the sleeve end in air light, as shown in FIG. 6a. The sleeve 1 shown in Figure 6b has a stepped conical end, which is also flanged airtight.

Die Figuren 7a und 7b zeigen eine Schutzkappe, bei der ein Ende 5 luftdicht verpreßt ist.Figures 7a and 7b show a protective cap in which one end 5 is pressed airtight.

Die Figuren 8a und 8b zeigen eine Schutzkappe mit abgesetztem Hals, deren verschlossenes Ende kegelförmig ausgebildet ist. Hierbei ist die kegelförmige Spitze der Schutzkappe luftdicht verschlossen, z. B. durch Umbördeln.Figures 8a and 8b show a protective cap with a lowered neck, the closed end of which is conical. Here, the conical tip of the protective cap is sealed airtight, for. B. by flanging.

Die Fig. 9a und 9b zeigen jeweils im Längsschnitt zwei als Raketenaufsatzhülsen verwendbare Schutzkappen, die eine konisch zulaufende Spitze, einen verdickten Körperabschnitt und einen zylindrischen Endabschnitt aufweisen, in welchen beispielsweise eine Raketentreibsatzhülse einsteckbar ist. Die Schutzkappe gemäß Fig. 9a weist in ihrem zylindrischen Endabschnitt eine ringförmige Verstärkung auf, während die Schutzkappe gemäß Fig. 9b aus einem Stück besteht.9a and 9b each show in longitudinal section two protective caps which can be used as missile attachment sleeves and which have a tapered tip, a thickened body portion and a cylindrical end portion, into which, for example, a missile propellant sleeve can be inserted. The protective cap according to FIG. 9a has an annular reinforcement in its cylindrical end section, while the protective cap according to FIG. 9b consists of one piece.

Von den vorgeschlagenen biologisch abbaubaren oder verrottbaren Materialien eignen sich Pappe, Karton, Vliesstoff, Papier oder Zellstoff gegebenenfalls aus Altpapier insbesondere für die Herstellung der Schutzkappe im Wickel- oder Pressverfahren.Of the proposed biodegradable or decomposable materials, cardboard, cardboard, nonwoven, paper or cellulose, if appropriate from waste paper, are particularly suitable for the production of the protective cap in the winding or pressing process.

Dagegen lassen sich die aus Mais oder Kartoffelstärke gewonnenen Materialien im herkömmlichen Spritzguß- oder Extrusionsverfahren zur Herstellung der Schutzkappe verarbeiten. Die aus Harnstoff bestehenden Materialien lassen sich zur Herstellung der erfindungsgemäßen Schutzkappe auch im Tiefzieh- oder Preßverfahren verarbeiten.In contrast, the materials obtained from corn or potato starch can be processed in the conventional injection molding or extrusion process to produce the protective cap. The materials consisting of urea can also be processed in the deep-drawing or pressing process to produce the protective cap according to the invention.
