Definitions
- the patent specification DE-C-156604 describes a method for producing bottle and tube sleeves from corrugated cardboard softened with glue vapors.
- these sleeves are completely wrapped around the bottles and vessels. to make them shockproof for handling.
- the wrapper of the invention consists of thin crepe paper with a thickness of only 0.20-0.35 mm. Softening with water is not necessary. Rather, the adaptations of the wrappings to the vessels and bottles are achieved by means of elasticity due to the specific fiber orientation and the defined stretching transverse to the longitudinal direction of the vessels.
- the coverings of the invention are practically wrinkle-free and crack-free, and they can be dried uniformly by quickly diffusing out the small amount of water from the glue dispersion.
- the invention relates to a method for producing aluminum-free casings for all kinds of vessels and for bottles according to the preamble of claim 1 (see DE-C-156604).
- the achievement of the object of the invention is also characterized in that crepe paper with an elongation transversely to the longitudinal direction of the vessel or bottle is used between 12 to 14%.
- the method of the invention is also characterized in that the crepe paper is used with a crepe height between 0.25 to 0.27 mm and a thickness between 0.26 to 0.30 mm.
- the method of the invention is further characterized in that the crepe paper is used with a basis weight between 60 to 120 g / m2 and in that it is used with a basis weight between 70 to 85 g / m2.
- crepe paper with a breaking load in the transverse direction for creping between 20 to 35 Nmm and / or with a breaking load in the longitudinal direction for creping between 25 to 35 Nmm is used.
- crepe paper with a breaking load in the transverse direction for creping between 25 to 30 Nmm and / or with a breaking load in the longitudinal direction for creping between 28 to 30 Nmm is used.
- crepe paper with a Gurley air permeability between 3.0 to 5.0 sec / 100 ml is used, and between 3.2 to 4.0 sec / 100 ml is used.
- the method of the invention is also characterized in that the envelopes are printed on underprinting ink with printing ink or with heavy metal-free pearlescent pigment before being glued on.
- the wrappings are glued to the bottle necks of beverage bottles such as beer bottles with a cylindrical shape, or with a conical shape, or with a continuous widening of the radius in the direction of the bottle bottom or the bulge, and in that the wrappings are spaced below a closure can be glued to this or to the lower edge thereof and in that the wrappings have a cut which projects beyond the closure at such a height that it is folded and glued practically tightly.
- a technical effect of the aluminum-free envelopes of the invention is based on the combination of essential features by the firm pressure in the dry state on the different spatial shapes of the vessels of all types and bottles, while practically avoiding the formation of folds.
- This technical effect is essentially caused by the elasticity of the wet-strength and alkali-resistant crepe paper, expressed as elongation in% to the vessels or bottles.
- a longitudinal expansion of, for example, 14% means the expansion of the length from 100 to 114 mm.
- the crepe height is understood to mean the distance in mm between the upper and lower points, i.e. between the vaulted mountain and the vaulted valley.
- the longitudinal stretching or the transverse stretching of the crepe paper is not suitable for adaptation to the surface of the containers or bottles.
- Another technical effect is formed by the weight per unit area. If this is too low, the crepe paper is not strong enough, if it is too large, the crepe paper lacks the elasticity to adapt to the surface of the containers or bottles.
- Another technical effect is the air permeability of the crepe paper. If this is too low, the liquid, especially the aqueous, phase of the dispersion of the adhesive cannot diffuse out of the crepe paper in practice.
- Air permeability is the Gurley measurement. Its definition is published in ISO standard 3687.
- Stretching the crepe paper of the invention means the increase in length in% of the length before stretching.
- glue dispersions are used, the liquid and aqueous phases of which diffuse out of the crepe paper and evaporate.
- the coverings are pressed on mechanically by means of brushes or sponges or rollers.
- the casings for all kinds of vessels and for bottles of the invention offer the technical advantage of substituting aluminum light metal foil with the same suitability for safe and permanent use for gluing and pressing onto the shaped surfaces of these objects.
- the wrapping of the invention made of crepe paper prevents pollution of the environment, in particular of the watercourses, and thus also of the soils due to the rotting to the C source for the microbial decomposition to humus product.
Abstract
Description
Durch Einwegflaschen und durch Recyclieren von Gefässen und Flaschen fuhren darauf angebrachte Umhüllungen aus Aluminium- (Al)- Folien durch deren Auflösen mit alkalischen Reinigungsflüssigkeiten oder durch Hydrolyse zur Bildung von wasserlöslichen Aluminaten, wie Na[Al(OH)₄], und dadurch zur Belastung der Umwelt, insbesondere der Gewässer.Through disposable bottles and through the recycling of containers and bottles, wrappings made of aluminum (Al) foils attached to them, by dissolving them with alkaline cleaning liquids or by hydrolysis, lead to the formation of water-soluble aluminates, such as Na [Al (OH) ₄], and thereby to stress the environment, especially water.
Sofern Aluminate aus Abwässern vor dem Einleiten in Vorfluter mit wässrigem Ammoniak,NH₄OH, ausgefällt werden, entsteht ein schlecht filtrierbares Hydroxid, Al(OH)₃. Der Einsatz dieses Fällungsmittels führt zu einer weiteren Belastung der Wasserläufe durch die Stickstoff-Komponente.If aluminates from wastewater are precipitated with aqueous ammonia, NH₄OH, before being discharged into the receiving water, a poorly filterable hydroxide, Al (OH) ₃ is formed. The use of this precipitant leads to a further pollution of the watercourses by the nitrogen component.
Auch das Ausrühren mit Kohlensäure, CO₂, ist technologisch aufwendig. Es entsteht ein gelförmiges Fällungsprodukt, das schlecht zu entwässern ist.Stirring with carbon dioxide, CO₂, is technologically complex. The result is a gel-like precipitate that is difficult to drain.
Diese Nachteile durch das Entstehen von löslichen Al- Verbindungen und durch die Notwendigkeit von Aufbereitungsstufen werden durch die Alumiminium- freie Umhüllungen der Erfindung vermieden.These disadvantages caused by the formation of soluble Al compounds and by the need for treatment stages are avoided by the aluminum-free coatings of the invention.
Die Patentschrift DE-C-156604 beschreibt ein Verfahren zur Herstellung von Flaschen- und Gefässhülsen aus mit Leimdämpfen weich gemachter Wellpappe.The patent specification DE-C-156604 describes a method for producing bottle and tube sleeves from corrugated cardboard softened with glue vapors.
Diese Hülsen werden im gedämpften Zustand vollständig um die Flaschen und Gefässe herumgelegt. um diese dadurch stossfest für die Handhabung zu machen.In the steamed state, these sleeves are completely wrapped around the bottles and vessels. to make them shockproof for handling.
Dieser ältere Stand der Technik hat sich nicht in die Praxis einführen können, denn beim Herumlegen lässt sich Einreissen und Faltenbildung nicht vermeiden.This older state of the art could not be used in practice, because tearing and wrinkling cannot be avoided.
Durch die Dicke der Pappe besteht nur eine geringe Durchlässigkeit für das Erweichungswasser. Es wird dadurch die Trocknung unregelmässig, und diese erfolgt wegen der Menge des Leimwassers zu langsam.Due to the thickness of the cardboard there is only a low permeability for the softening water. As a result, the drying becomes irregular and this is too slow because of the amount of glue water.
Ein erheblicher Nachteil besteht darin, dass sich beim Ablösen der Umhüllung in alkalischer Phase eine feinteilige, faserige, breiförmige Masse bildet, die schlecht und nur langsam filtrierbar ist.A considerable disadvantage is that when the coating is removed in the alkaline phase, a finely divided, fibrous, pasty mass is formed which is poorly and only slowly filterable.
Dagegen besteht die Umhüllung der Erfindung aus dünnem Kreppapier einer Dicke von nur 0,20- 0,35 mm. Das Erweichen mit Wasser ist nicht erforderlich. Es wird vielmehr das Anpassen der Umhüllungen an die Gefässe und Flaschen durch den bestimmten Faserverlauf und durch die definierte Dehnung quer zur Längsrichtung der Gefässe durch Elastizität erzielt.In contrast, the wrapper of the invention consists of thin crepe paper with a thickness of only 0.20-0.35 mm. Softening with water is not necessary. Rather, the adaptations of the wrappings to the vessels and bottles are achieved by means of elasticity due to the specific fiber orientation and the defined stretching transverse to the longitudinal direction of the vessels.
Die Umhüllungen der Erfindung sind praktisch falten- und rissfrei,und diese können durch rasches Herausdiffundieren der geringen Wassermenge aus der Leimdispersion gleichmässig getrocknet werden.The coverings of the invention are practically wrinkle-free and crack-free, and they can be dried uniformly by quickly diffusing out the small amount of water from the glue dispersion.
Beim Ablösen zur Entsorgung bleibt diese Umhüllung nur um den Hals der Gefässe als Einheit erhalten und kann dadurch leicht abgetrennt werden. Die definierte Krepphöhe gestattet auch ein Bedrucken vor dem Ankleben.When detached for disposal, this covering only remains as a unit around the neck of the vessels and can therefore be easily removed. The defined crepe height also allows printing before gluing.
Gegenstand der Erfindung ist ein Verfahren zur Herstellung aluminium-freier Umhüllungen für Gefässe aller Art und für Flaschen nach dem Oberbegriff des Anspruches 1 (siehe DE-C-156604).The invention relates to a method for producing aluminum-free casings for all kinds of vessels and for bottles according to the preamble of claim 1 (see DE-C-156604).
Es ist die Aufgabe der Erfindung aluminiumfreie Umhüllungen mit dem Verfahren der Erfindung herzustellen, die eine technologisch einfache Entsorgung gestatten.It is the object of the invention to produce aluminum-free envelopes with the method of the invention, which allow technologically simple disposal.
Die Lösung der Aufgabe der Erfindung ist im kennzeichnenden Teil des Anspruches 1 definiert.The solution to the problem of the invention is defined in the characterizing part of claim 1.
Diese ist dadurch gekennzeichnet,dass hydrophobes, praktisch nassfestes und laugenfestes Kreppapier mit einem Verlauf der Fasern quer zur Kreppung und mit einer Dehnung quer zur Längsrichtung des Gefässes oder der Flasche zwischen 10 bis 2o % und mit einer Krepphöhe zwischen 0,20 bis 0,30 mm bei einer Dicke zwischen 0,20 bis 0,35 mm verwendet wird und das Kreppapier vor dem Andrücken angeklebt wird.This is characterized in that hydrophobic, practically wet-strength and alkali-resistant crepe paper with a course of the fibers transverse to the crepe and with an elongation transverse to the longitudinal direction of the vessel or bottle between 10 to 20% and with a crepe height between 0.20 to 0.30 mm is used for a thickness between 0.20 to 0.35 mm and the crepe paper is glued on before pressing.
Die weitere und bevorzugte Ausgestaltung der erfindungsgeeräßen Lösung ist in den Unteransprüchen definiert.The further and preferred embodiment of the solution according to the invention is defined in the subclaims.
Die Lösung der Aufgabe der Erfindung ist auch dadurch gekennzeichnet, dass Kreppapier mit einer Dehnung quer zur Längsrichtung des Gefässes oder der Flasche zwischen 12 bis 14 % verwendet wird.The achievement of the object of the invention is also characterized in that crepe paper with an elongation transversely to the longitudinal direction of the vessel or bottle is used between 12 to 14%.

Das Verfahren der Erfindung ist ferner dadurch gekennzeichnet, dass das Kreppapier mit einem Flächengewicht zwischen 60 bis 120 g/m² verwendet wird, und dadurch, dass dieses mit einem Flächengewicht zwischen 70 bis 85 g/m² verwendet wird.The method of the invention is further characterized in that the crepe paper is used with a basis weight between 60 to 120 g / m² and in that it is used with a basis weight between 70 to 85 g / m².
Dieses ist auch dadurch gekennzeichnet, dass Kreppapier mit einer Bruchlast in Querrichtung zur Kreppung zwischen 20 bis 35 Nmm und/oder mit einer Bruchlast in Längsrichtung zur Kreppung zwischen 25 bis 35 Nmm verwendet wird.This is also characterized in that crepe paper with a breaking load in the transverse direction for creping between 20 to 35 Nmm and / or with a breaking load in the longitudinal direction for creping between 25 to 35 Nmm is used.
Dieses ist auch noch dadurch gekennzeichnet, dass Kreppapier mit einer Bruchlast in Querrichtung zur Kreppung zwischen 25 bis 30 Nmm und/oder mit einer Bruchlast in Längsrichtung zur Kreppung zwischen 28 bis 30 Nmm verwendet wird.This is also characterized in that crepe paper with a breaking load in the transverse direction for creping between 25 to 30 Nmm and / or with a breaking load in the longitudinal direction for creping between 28 to 30 Nmm is used.
Dieses ist weiter dadurch gekennzeichnet, dass Kreppapier mit einer Luftdurchlässigkeit nach Gurley zwischen 3,0 bis 5,0 sec/ 100 ml verwendet wird, und zwischen 3,2 bis 4,0 sec/ 100 ml verwendet wird.This is further characterized in that crepe paper with a Gurley air permeability between 3.0 to 5.0 sec / 100 ml is used, and between 3.2 to 4.0 sec / 100 ml is used.
Das Verfahren der Erfindung ist auch dadurch gekennzeichnet, dass die Umhüllungen vor dem Ankleben mit Druckfarbe oder mit schwermetallfreiem Perlglanzpigment auf Unterdruckfarbe bedruckt werden.The method of the invention is also characterized in that the envelopes are printed on underprinting ink with printing ink or with heavy metal-free pearlescent pigment before being glued on.
Dieses ist weiter dadurch gekennzeichnet, dass die Umhüllungen auf Flaschenhälse von Getränkeflaschen wie Bierflaschen mit zylindrischer Form, oder mit konischer, oder mit kontinuierlicher Verbreiterung des Radius in Richtung zum Flaschen boden oder zur Bauchung angeklebt werden und dadurch, dass die Umhüllungen unterhalb eines Verschlusses mit Abstand zu diesem oder bis zu dessen unteren Rand angeklebt werden und dadurch, dass die Umhüllungen einen Zuschnitt aufweisen, der über den Verschluss mit einer solchen Höhe hinausragt, dass diese praktisch fest anliegend eingefaltet und angeklebt wird.This is further characterized in that the wrappings are glued to the bottle necks of beverage bottles such as beer bottles with a cylindrical shape, or with a conical shape, or with a continuous widening of the radius in the direction of the bottle bottom or the bulge, and in that the wrappings are spaced below a closure can be glued to this or to the lower edge thereof and in that the wrappings have a cut which projects beyond the closure at such a height that it is folded and glued practically tightly.
Ein technischer Effekt der Aluminium- freien Umhüllungen der Erfindung beruht auf der Kombination essentieller Merkmale durch die feste Anpressung im Trockenzustand an die unterschiedlichen Raumformen der Gefässe aller Art und Flaschen unter praktischer Vermeidung der Bildung von Faltungen.A technical effect of the aluminum-free envelopes of the invention is based on the combination of essential features by the firm pressure in the dry state on the different spatial shapes of the vessels of all types and bottles, while practically avoiding the formation of folds.
Dieser technische Effekt ist wesentlich durch die Elastizität des nassfesten und Laugenfesten Kreppapiers, ausgedrückt als Dehnung in % zu den Gefässen oder Flaschen, bewirkt.This technical effect is essentially caused by the elasticity of the wet-strength and alkali-resistant crepe paper, expressed as elongation in% to the vessels or bottles.
Sofern dieser Wert zu niedrig ist, wird die Faltenbildung nicht sicher ausgeschlossen, und es entstehen dadurch Ausschuss bei den gefüllten Flaschen.If this value is too low, wrinkling is not reliably ruled out, and this results in rejects in the filled bottles.
Sofern dieser Wert zu hoch ist, ist das sichere Anlegen der Umhüllungen an die unterschiedliche Oberfläche der Gefäss- und Flaschenhälse nicht gegeben.If this value is too high, there is no safe application of the coverings to the different surface of the tube and bottle necks.
Nur der erfundene, ausgewählte kritische Bereich der Dehnung des Kreppapieres gestattet sicher die optimale Geschmeidigkeit zur Anpassung an die verschieden ausgebildeten Formen der Oberfläche der Gefässe und Flaschen.Only the invented, selected critical area of crepe paper stretching allows the optimal suppleness to adapt to the different forms of the surface of the jars and bottles.
Unter einer Längsdehnung von beispielsweise 14% wird die Ausdehnung der Länge von 100 auf 114 mm verstanden.A longitudinal expansion of, for example, 14% means the expansion of the length from 100 to 114 mm.
Ein anderer technischer Effekt der Aluminium- freien Umhüllungen der Gefässe und Flaschen basiert auf der Höhe der Kreppung der Umhüllung. Unter der Krepphöhe wird der Abstand zwischen dem oberen und unteren Punkt,also zwischen dem Wölbungsberg und Wölbungstal in mm verstanden.Another technical effect of the aluminum-free wrapping of the containers and bottles is based on the height of the crepe of the wrapping. The crepe height is understood to mean the distance in mm between the upper and lower points, i.e. between the vaulted mountain and the vaulted valley.
Wenn der kritische Bereich überschritten wird, besteht bei der technischen Druckgeschwindigkeit keine ausreichend gleichmässige Bedruckung der Umhüllungen in der Druckmaschine.If the critical range is exceeded, there is no sufficiently uniform printing of the envelopes in the printing press at the technical printing speed.
Wenn der kritische Wert unterschritten wird, ist die Längsdehnung bzw. die Querdehnung des Kreppapieres nicht zur Anpassung an die Oberfläche der Gefässe oder Flaschen geeignet.If the critical value is undershot, the longitudinal stretching or the transverse stretching of the crepe paper is not suitable for adaptation to the surface of the containers or bottles.
Es tritt beispielsweise am unteren Ende ein Abstand auf, der nicht zum Ankleben führt.For example, there is a gap at the lower end that does not lead to sticking.
Ein anderer technischer Effekt wird durch das Flächengewicht gebildet.Wenn dieses zu gering ist, besteht keine ausreichende Festigkeit des Kreppapiers, wenn dieses zu gross ist, dann fehlt dem Kreppapier die Elastizität zur Anpassung an die Oberfläche der Gefässe oder Flaschen.Another technical effect is formed by the weight per unit area. If this is too low, the crepe paper is not strong enough, if it is too large, the crepe paper lacks the elasticity to adapt to the surface of the containers or bottles.
Ein anderer technischer Effekt liegt in der Luftdurchlässigkeit des Kreppapieres.Wenn diese zu gering ist, dann kann die flüssige,insbesondere die wässrige Phase der Dispersion des Klebemittels nicht für die Praxis ausreichend aus dem Kreppapier diffundieren.Another technical effect is the air permeability of the crepe paper. If this is too low, the liquid, especially the aqueous, phase of the dispersion of the adhesive cannot diffuse out of the crepe paper in practice.
Wenn die Luftdurchlässigkeit zu gross ist, dann besteht für die Praxis keine ausreichende Festigkeit des Kreppapiers.If the air permeability is too high, the crepe paper is not sufficiently strong in practice.
Unter Luftdurchlässigkeit wird die Messung nach Gurley verstanden. Diese ist in ihrer Definition in ISO- Norm 3687 veröffentlicht.Air permeability is the Gurley measurement. Its definition is published in ISO standard 3687.

Unter Dehnung des Kreppapiers der Erfindung wird die Zunahme der Länge in % zur Länge vor der Dehnung verstanden.Stretching the crepe paper of the invention means the increase in length in% of the length before stretching.
Zum Ankleben werden für sich bekannte Leimdispersionen verwendet, deren flüssige, wie wässrige Phase, aus dem Kreppapier herausdiffundiert und verdunstet.For gluing, known glue dispersions are used, the liquid and aqueous phases of which diffuse out of the crepe paper and evaporate.
Das Andrücken der Umhüllungen erfolgt maschinell mittels Bürsten, oder Schwämme, oder Rollen.The coverings are pressed on mechanically by means of brushes or sponges or rollers.
Aluminium-freie Umhüllungen gemäss der Erfindung (Nr.1 und 2) und solche mit ungeeigneten Parametern (3 und 4) sind nachstehend beschrieben:
Die Gegenüberstellung der Umhüllungen aus Kreppapier gemäss der Erfindung, Nr. 1 und 2, zu ungeeigneten Umhüllungen, Nr. 3 und 4, bestätigt, dass die technische Eignung zur Lösung der Aufgabe der Erfindung sich überraschend aus der Kombination der Parameter ergibt.The comparison of the wrappings made of crepe paper according to the invention, Nos. 1 and 2, to unsuitable wrappings, No. 3 and 4, confirms that the technical suitability for achieving the object of the invention is surprisingly obtained from the combination of the parameters.
Erst wenn diese Kombination als Auswahl essentieller Parameter erfunden ist, kann die Aufgabe der Erfindung sicher gelöst werden.Only when this combination is invented as a selection of essential parameters can the object of the invention be reliably achieved.
Die Umhüllungen für Gefässe aller Art und für Flaschen der Erfindung bietet den technischen Vorteil der Substitution von Leichtmetallfolie aus Aluminium mit der gleichen Eignung für die sichere und dauerhafte Verwendung zum Aufkleben und Andrücken auf die geformten Oberflächen dieser Gegenstände.The casings for all kinds of vessels and for bottles of the invention offer the technical advantage of substituting aluminum light metal foil with the same suitability for safe and permanent use for gluing and pressing onto the shaped surfaces of these objects.
Die Umhüllung der Erfindung aus Kreppapier verhindert die Belastung der Umwelt, insbesondere der Wasserläufe,und damit auch der Böden durch die Verrottung zur C- Quelle für die mikrobielle Zersetzung zu Humusprodukt.The wrapping of the invention made of crepe paper prevents pollution of the environment, in particular of the watercourses, and thus also of the soils due to the rotting to the C source for the microbial decomposition to humus product.
