Description

Die Erfindung bezieht sich auf einen Deckel zum Verschliessen eines Behälters, der an seinem oberen Rand eine umlaufende Verdickung aufweist, wobei der Deckel aus einer Kunststoffolie tiefgezogen oder im Spritzgussverfahren hergestellt ist und einen die Verdickung des Behälters übergreifenden, im wesentlichen nach unten gerichteten Randflansch aufweist.The invention relates to a lid for closing a container having at its upper edge a circumferential thickening, wherein the lid of a plastic film is deep-drawn or manufactured by injection molding and has a thickening of the container cross-shaped, substantially downwardly directed edge flange.

Derartige Deckel sind in einer Vielzahl bekannt. Sie werden im allgemeinen maschinell auf den Behälter aufgebracht und halten dort meist ausreichend gut.Such covers are known in a variety. They are generally applied by machine to the container and usually hold there sufficiently well.

Ein solcher bekannter Deckel ist beispieslweise aus der U5R E258 797 ESuch a known lid is, for example, the U5R E258 797 E

Der Erfindung liegt die Aufgabe zugrunde, einen Deckel der genannten Art so auszugestalten, dass er von Hand auf den Behälter aufgebracht werden kann und dabei einen sicheren Verschluss gewährleistet.The invention has the object of providing a cover of the type mentioned in such a way that it can be applied by hand to the container while ensuring a secure closure.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Deckel die Merkmale des Anspruchs 1 aufweist.This object is achieved in that the lid has the features of claim 1.

Durch diese Ausgestaltung mit einer Vielzahl von Vorsprüngen wird zum Aufbringen des Deckels ein nicht zu geringer Kraftaufwand benötigt, der ein deutlich hörbares Aufschnappen des Deckels zur Folge hat. Damit ist gewährleistet, dass das vollständige Aufbringen des Deckels erfolgt und akustisch kontrolliert werden kann. Zudem wird durch diese Vielzahl von Vorsprüngen auch ein sicherer Halt des Deckels am Behälter gewährleistet.This embodiment with a plurality of projections for applying the lid a not too small force is required, which has a clearly audible snapping the lid result. This ensures that the complete application of the lid is done and can be controlled acoustically. In addition, a secure hold of the lid on the container is ensured by this large number of projections.

Damit ist gewährleistet, dass sich der Deckel mit seinen Vorsprüngen nicht am Rand des Behälters verhakt.This ensures that the lid with its projections does not catch on the edge of the container.

Dadurch wird trotz der Vielzahl an Vorsprüngen der Deckel noch von Hand auf den Behälter aufsetzbar, während durch die steileren inneren Dachflächen ein sehr effektiver Halt gewährleistet wird.As a result, despite the large number of projections, the lid can still be placed on the container by hand, while a very effective hold is ensured by the steeper inner roof surfaces.

Eine weitere vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass die Vorsprünge in einem geringen Abstand von einander angeordnet sind.A further advantageous embodiment of the invention is characterized in that the projections are arranged at a small distance from each other.

Dadurch wird eine sehr gute Steifigkeit des Deckels erzielt, was besonders beim Aufsetzen des Deckels auf den Behälter zum Tragen kommt.As a result, a very good rigidity of the lid is achieved, which is particularly important when placing the lid on the container to fruition.

Als sehr vorteilhaft hat es sich dabei erwiesen, wenn der gegen den Behälter eingezogene bzw. ausgestellte Deckelflächen-Teil ringförmig ausgebildet ist.It has proven to be very advantageous in this case if the lid surface part retracted or raised against the container is annular.

Eine weitere vorteilhafte Ausgestaltung der Erfindung ist durch gekennzeichnet, dass der innerhalb des ringförmigen Deckelflächen-Teils liegende MittendeckelaAbschnitt topfförmig ausgebildet ist.A further advantageous embodiment of the invention is characterized in that the center cover section lying within the annular cover surface part is cup-shaped.

Das trägt ebenfalls zur weiteren Versteifung des Deckels bei.This also contributes to the further stiffening of the lid.

Dies wird noch unterstützt, wenn gemäß einer weiteren Ausgestaltung der Erfindung der topfförmige MittendeckelaAbschnitt nach aussen ausgeformt ist.This is further assisted if, according to a further embodiment of the invention, the cup-shaped central lid section is formed outwardly.

Ebenfalls als sehr vorteilhaft hat es sich erwiesen, wenn gemäß einer weiteren Ausgestaltung der Erfindung zwischen dem topfförmigen Mittendeckelabschnitt und dem ringförmigen Deckelflächen-Teil eine weitere, im wesentlichen eben und ringförmig ausgebildete Deckelfläche vorgesehen ist.It has also proven to be very advantageous if, according to a further embodiment of the invention, a further, essentially planar and annular cover surface is provided between the cup-shaped center cover section and the annular cover surface part.

Als sehr vorteilhaft hat es sich auch ergeben, wenn im Deckel mehrere Vertiefungen bzw. Erhebungen vorgesehen sind.It has also proven to be very advantageous if several depressions or elevations are provided in the lid.

Erfindungsgemäß sind die Vertiefungen bzw. Erhebungen im ringförmigen Deckelflächen-Teil vorgesehen.According to the invention, the recesses or elevations are provided in the annular cover surface part.

Dabei ist es besonders vorteilhaft, wenn die Vertiefungen an die ebene Deckelfläche anschliessend angeordnet sind.It is particularly advantageous if the depressions are subsequently arranged on the flat lid surface.

Besonders günstig ist es dabei, wenn gemäß einer weiteren Ausgestaltung der Erfindung die Vertiefungen zur ebenen Deckelfläche hin eine größere Tiefe aufweisen als zum Randflansch hin.It is particularly advantageous if, according to a further embodiment of the invention, the recesses towards the flat top surface have a greater depth than the edge flange.

Damit wird die Steifigkeit des Deckels ganz wesentlich erhöht. Das Deckelmaterial kann dünner ausgebildet werden, was eine nicht unerhebliche Materialersparnis zur Folge hat.Thus, the rigidity of the lid is significantly increased. The lid material can be made thinner, which has a significant material savings result.

Dabei hat es sich als besonders vorteilhaft erwiesen, wenn gemäß einer weiteren Ausgestaltung der Erfindung die Vertiefungen zur ebenen Deckelfläche hin eine größere Breite aufweisen als zum Randflansch hin.It has proved to be particularly advantageous if, according to a further embodiment of the invention, the recesses towards the flat top surface have a greater width than the edge flange.

Hierdurch wird zusätzlich zu der erzeugten strukturellen Steifigkeit noch eine Elastizität in den Deckel eingebracht, die ein noch besseres und sichereres Einschnappen des Deckels auf dem Behälter sicherstellt.As a result, in addition to the structural stiffness produced, elasticity is also introduced into the lid, which ensures even better and safer snap-fastening of the lid to the container.

Eine weitere, sehr vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass unterschiedlich gestaltete Vertiefungen und Erhebungen vorgesehen sind, die jeweils abwechselnd angeordnet sind.Another, very advantageous embodiment of the invention is characterized in that differently shaped depressions and elevations are provided, which are each arranged alternately.

Bei einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass innerhalb des Bodens des topfförmigen Mittendeckelabschnittes eine Sollbruchstelle oder Durchbrechung vorgesehen ist.In a further advantageous embodiment of the invention, it is provided that a predetermined breaking point or opening is provided within the bottom of the cup-shaped central lid section.

Über diese Sollbruchstelle oder Durchbrechung kann beispielsweise ein Trinkhalm in den Behälter eingeführt werden.About this breaking point or opening, for example, a drinking straw are introduced into the container.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist die Sollbruchstelle und/oder Durchbrechung durch zwei kreuzfönnig angeordnete Schnittlinien gebildet.According to an advantageous embodiment of the invention, the predetermined breaking point and / or opening is formed by two cross-cut lines arranged.

Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt darin, dass in den Deckel unterschiedliche Informationen eingeprägt sind.A further advantageous embodiment of the invention is that in the lid different information is stamped.

Dabei ist es besonders vorteilhaft, wenn gemäß einer weiteren Ausgestaltung der Erfindung die Informationen in der ebenen Deckelfläche angeordnet sind.It is particularly advantageous if according to a further embodiment of the invention, the information in the flat lid surface are arranged.

Dadurch sind die Informationen gut sichtbar, aber dennoch vor Beschädigungen geschützt.As a result, the information is clearly visible, yet protected from damage.

Es hat sich erfindungsgemäß auch als sehr vorteilhaft erwiesen, wenn eine innere Dichtlippe oder Dichtflanke vorgesehen ist, welche sich an der Innenseite des Behälters eng anzulegen vermag.It has also proved to be very advantageous according to the invention if an inner sealing lip or sealing flank is provided, which is able to fit snugly against the inside of the container.

Damit wird eine sehr gute Dichtheit des Deckels gegenüber dem Behälter sichergestellt. Im Behälter befindliche Flüssigkeit wird daran gehindert bis an die Verdickung zu gelangen. Durch die doppelte Dichtung an Dichtlippe bzw. Dichtflanke und Verdickung ist der mit dem erfindungsgemäßen Deckel verschlossene Behälter auch schwallwasserdicht.This ensures a very good tightness of the lid against the container. Liquid in the container is prevented from reaching the thickening. Due to the double seal on the sealing lip or sealing flank and thickening of the closed container with the lid according to the invention is also splash water resistant.

Mit 1 ist in Fig. ein becherförmiger Behälter bezeichnet, der beispielsweise aus beschichtetem Karton gewickelt ist und an seinem oberen, offenen Ende eine nach aussen gewickelte Rolle 2 aufweist. Auf diesen Behälter 1 ist ein Deckel 3 aufgesetzt, der aus einer Kunststoffolie im Tiefziehverfahren oder durch Spritzgiessen hergestellt ist und einen Randflansch 4 enthält, der nach unten weist und leicht nach aussen ausgestellt ist. In diesem Randflansch 4 ist eine Vielzahl von nach innen gerichteten Vorsprüngen 5 vorgesehen, die im auf den Behälter 1 aufgesetzten Zustand unter die Rolle 2 greifen und den Deckel am Behälter festlegen. Diese Vorsprünge 5 sind im Querschnitt gesehen dachförmig ausgebildet, wobei die nach unten gerichtete Dachfläche weniger steil ausgebildet ist als die obere Dachfläche. Dadurch kann die untere Dachfläche leicht auf die Rolle 2 aufgleiten, während die obere Dachflache weniger leicht über die Rolle 2 gleitet und damit dem Deckel 3 einen festen Halt gewährt.1 designates a cup-shaped container in FIG. 1, which is wound, for example, from coated cardboard and has a roll 2 wound outwards at its upper, open end. On this container 1, a lid 3 is placed, which is made of a plastic film by thermoforming or injection molding and includes an edge flange 4, which faces down and is slightly exposed to the outside. In this edge flange 4, a plurality of inwardly directed projections 5 are provided, which engage in the placed on the container 1 state under the roller 2 and set the lid on the container. These projections 5 are formed roof-shaped in cross-section, wherein the downwardly directed roof surface is less steep than the upper roof surface. This allows the lower roof surface easily slide onto the roller 2, while the upper roof surface less easily slides over the roller 2 and thus gives the cover 3 a firm grip.

Die Vorsprünge 5 sind darüber hinaus sehr eng nebeneinander angeordnete, so dass der Deckel insgesamt sehr fest auf dem Behälter hält.Moreover, the projections 5 are arranged very close to one another, so that the lid as a whole holds very firmly on the container.

Vom Randflansch 4 ausgehend schliesst an einen wenigstens annähernd senkrecht verlaufenden Absatz 6 nach innen ein Deckelflächen-Teil 7 an, der schräg nach innen eingezogen ist. Dieser Deckelflächen-Teil 7 kann jedoch auch nach aussen ausgestellt sein, wie in den Figuren 7, 8, 9, 10 und 11 dargestellt. Dort ist der nach aussen ausgestellte Deckelflächenteil mit der Ziffer 71 bezeichnet. Im Mittelabschnitt des Deckels ist eine Deckelflächen 8 vorgesehen, der beim dargestellten Ausführungsbeispiel kreisförmig um einen erhaben gegenüber der Deckelfläche 7 bzw. 71 und dem Deckelflächen-Abschnitt angeordneten und topfförmig ausgebildeten Mittendeckelabschnitt 9 angeordnet ist.Starting from the edge flange 4, a cover surface part 7, which is drawn in obliquely inwards, adjoins an at least approximately vertically extending shoulder 6 inwards. However, this cover surface part 7 may also be issued to the outside, as in the FIGS. 7 . 8, 9, 10 and 11 shown. There, the issued to the outside cover surface part is designated by the numeral 71. In the middle portion of the lid, a lid surfaces 8 is provided, which is arranged in the illustrated embodiment in a circle around a raised relative to the lid surface 7 and 71 and the lid surface portion arranged and cup-shaped central lid portion 9.

Die Deckelfläche 8 ist im wesentlichen eben ausgebildet. Im Deckelflächenteil 7 bzw. 71 sind gleichmässig über den Umfang Vertiefungen 10 angeordnet, die nicht nur die Deckelflächen 8, sondern den gesamten Deckel 3 versteifen. Die Vertiefungen 10 weisen dabei zur Deckelmitte hin eine größere Tiefe als zum Randflansch 4 hin auf. Zudem ist die Breite der Vertiefungen 10 an ihrem inneren Ende größer als an ihrem äußeren Ende.The lid surface 8 is formed substantially flat. In the cover surface part 7 and 71, recesses 10 are uniformly arranged over the circumference, which stiffen not only the cover surfaces 8 but the entire cover 3. The recesses 10 point towards the center of the lid to a greater depth than the edge flange 4 down. In addition, the width of the recesses 10 is greater at its inner end than at its outer end.

Die Vertiefungen 10 grenzen direkt an die Deckelflächen 8 an, können aber auch einen Abstand zu diesen einnehmen.The depressions 10 directly adjoin the cover surfaces 8, but may also be at a distance therefrom.

Zwischen benachbarten Vertiefungen 10 können noch Erhebungen 11 vorgesehen sein, die in den gezeigten Beispielen einen ovalen Querschnitt aufweisen und abgerundet ausgebildet sind. Diese sorgen für eine weitere Versteifung des Deckels 3.Between adjacent recesses 10 elevations 11 may still be provided, which have an oval cross-section in the examples shown and are rounded. These provide for a further stiffening of the lid 3.

Im Mittendeckelabschnitt 9 sind zwei gekreuzte Schnittlinien 12 vorgesehen, die eine Schwächung des Deckelmaterials erzeugen. In diese durch diese beiden Schnittlinien 12 definierte Öffnung kann ein Strohhalm in den mit dem Deckel 3 verschlossenen Becher 1 eingesteckt werden.In the middle lid section 9, two crossed cutting lines 12 are provided, which produce a weakening of the lid material. In this opening defined by these two cutting lines 12, a straw can be inserted into the closed cup 3 with the cup 1.

Die Wände des Behälters 1 sind zur Rolle 2 hin wenigstens geringfügig nach aussen geneigt.The walls of the container 1 are inclined towards the roller 2 at least slightly outwards.

Der Absatz 6 dagegen ist senkrecht ausgebildet, so daß dieser wenigstens mit seiner unteren Kante gegen die Wände des Behälters 1 gedrückt wird und so für eine Abdichtung sorgt. Im Behälter enthaltene Flüssigkeit kann so nicht bis zur Rolle 2 und zum Randflansch 4 gelangen. Dadurch ist der Behälter 1 wenigstens schwalldicht verschlossen.The paragraph 6, however, is formed vertically so that it is pressed at least with its lower edge against the walls of the container 1 and so provides a seal. Liquid contained in the container can not reach the roller 2 and the edge flange 4 in this way. As a result, the container 1 is closed at least baffle.

Es ist dabei auch denkbar, daß der Absatz 6 annähernd parallel zu den Wänden verläuft und so eine Abdichtung geschaffen wird.It is also conceivable that the paragraph 6 runs approximately parallel to the walls and so a seal is created.

Der Deckel 3 kann vor allem im Bereich der Deckelflächen 8 Beschriftungen tragen, die beispielsweise eingeprägt sein können.The cover 3 can carry 8 inscriptions, especially in the area of the lid surfaces, which can be embossed, for example.

Die Kunststoff-Folie aus der der Deckel 3 hergestellt wird, kann aus ein- oder mehrlagigem Material gefertigt sein. Es ist denkbar, daß hierfür PS, PE, PP, PET oder aber auch biologische Materialien wie beispielsweise PLA eingesetzt werden. Andere Materialien sind denkbar. Der Deckel kann sowohl auf seiner Innenseite als auch auf seiner Aussenseite beschichtet sein. An Beschichtungen ist zum beispielsweise eine Metallisierung oder ein Antihaft- oder Trennmittel denkbar.The plastic film from which the lid 3 is made, can be made of single or multilayer material. It is conceivable that PS, PE, PP, PET or even biological materials such as PLA be used for this purpose. Other materials are conceivable. The lid can be coated both on its inside and on its outside. On coatings for example, a metallization or a non-stick or release agent is conceivable.

Es ist auch denkbar, daß bei Einsatz von biologisch abbaubaren und dabei oftmals wasserlöslichen Materialien die Innenseite des Deckelmaterials mit einer dünnen PE Schicht oder einem anderen Kunststoff geschützt ist.It is also conceivable that when using biodegradable and often water-soluble materials, the inside of the lid material is protected with a thin PE layer or other plastic.

Der Deckel 3 kann mittels eines beliebigen thermoplastischen Umformungsverfahren ausgeformt werden.The lid 3 can be formed by any thermoplastic forming process.

Aufgrund des beschriebenen strukturellen Aufbaus des Deckels 3 rastet dieser akustisch wahrnehmbar auf der Rolle 2 ein und weist eine hervorragende Stabilität auf.Due to the described structural design of the lid 3, this engages audibly perceptible on the roller 2 and has excellent stability.

Zudem ist durch die Stabilität und die Ausrüstung mit einer Dichtflanke eine hervorragende Schwalldichtigkeit gewährleistet. Die Rolle 2 ist vor Flüssigkeit geschützt, bildet aber in Kombination mit dem Randflansch 4 eine weitere Abdichtung.In addition, the stability and the equipment with a sealing flank ensures excellent surge-tightness. The roller 2 is protected from liquid, but forms in combination with the edge flange 4 another seal.

Aufgrund der hohen Stabilität ist es möglich die Materialdicke des Deckels 3 erheblich zu reduzieren, wodurch Material und Kosten eingespart werden können.Due to the high stability, it is possible to significantly reduce the material thickness of the lid 3, whereby material and costs can be saved.
