Description

Die Erfindung betrifft eine längliche Isoliervorrichtung für Dosen oder Flaschen.The invention relates to an elongated insulating device for cans or bottles.

Solche Isoliervorrichtungen sind in Form von einseitig offenen isolierten Zylindern, z.B. doppelwandigen Zylindern, bekannt, die man auf den Tisch stellen kann und dann die gekühlte Dose oder Flasche dort hineinstellt. Diese Isoliervorrichtung hat den Nachteil, sehr aufwendig konstruiert zu sein und entsprechend teuer zu sein, viel Platz einzunehmen und nur dann wirksam zu sein, wenn sie aufrecht steht, da sie nur wirksam ist, solange die kalte Luft zwischen Flasche und Zylinderwand aufgrund ihrer größeren Dichte in der Isoliervorrichtung verbleibt. Dies ist nicht mehr der Fall, wenn man den Zylinder z.B. hinlegt oder die Flasche zum Leeren entnehmen muß.Such isolation devices are in the form of insulated cylinders open on one side, e.g. double-walled cylinders, known that you can put on the table and then put the chilled can or bottle in there. This isolating device has the disadvantage of being very complex in construction and correspondingly expensive, taking up a lot of space and only being effective when it is standing upright, since it is only effective as long as the cold air between the bottle and the cylinder wall is due to its greater density remains in the isolation device. This is no longer the case if you e.g. lies down or has to remove the bottle to empty it.

Die Aufgabe der Erfindung besteht in der Schaffung einer Isoliervorrichtung, mit der einerseits Dosen oder Flaschen sehr wirksam kühl gehalten werden können, und die andererseits einfach und kostengünstig hergestellt werden kann sowie sehr leicht ist.The object of the invention is to provide an insulating device with which cans or bottles can be kept very effectively cool on the one hand, and which on the other hand can be produced simply and inexpensively and is very light.

Die erfindungsgemäße Lösung besteht darin, daß die Isoliervorrichtung aus einem flächigen, schlecht wärmeleitenden Trägermaterial hergestellt ist, das auf beiden Oberflächen mit einer Metallschicht versehen ist, daß sie an beiden Stirnflächen Öffnungen aufweist, von denen zumindest eine einen zu öffnenden oder zu entfernenden Deckel aufweist.The solution according to the invention is that the insulating device consists of a flat, poorly heat-conducting Carrier material is produced, which is provided on both surfaces with a metal layer, that it has openings on both end faces, of which at least one has a lid to be opened or removed.

Statt aufwendiger Metall-, Kunststoff- oder Glasbehälter, wie sie bisher verwendet wurden, besteht die Isoliervorrichtung lediglich aus einem schlecht wärmeleitenden Trägermaterial mit Metallbeschichtungen. Das Trägermaterial kann z.B. Zellstoff, Papier oder Pappe sein, so daß es sehr billig ist. Da man das Trägermaterial aufgrund der Beschichtung nicht sieht, könnten hier wiederverwendete Materialien eingesetzt werden. Obwohl die Isoliervorrichtung aus so einfachen Materialien hergestellt ist, erhält man eine erstaunliche Isolierwirkung. Die Getränke bleiben über Stunden kühl. Dabei ist es ein wesentliches Merkmal, daß die Dosen oder Flaschen verhältnismäßig eng in die Isoliervorrichtung eingepaßt werden, die Isoliervorrichtung also einen Innendurchmesser hat, der dem Außendurchmesser der Dosen oder Flaschen entspricht. Dieses Merkmal ist wie gesagt ganz wesentlich.Instead of complex metal, plastic or glass containers, as they have been used so far, the insulating device consists only of a poorly heat-conducting carrier material with metal coatings. The carrier material can e.g. Be pulp, paper or cardboard so it's very cheap. Since the carrier material cannot be seen due to the coating, reused materials could be used here. Even though the isolating device is made from such simple materials, an amazing isolating effect is obtained. The drinks stay cool for hours. It is an essential feature that the cans or bottles are fitted into the insulating device relatively closely, that is to say the insulating device has an inner diameter which corresponds to the outer diameter of the cans or bottles. As I said, this characteristic is very important.

Da sich damit zwischen Dose oder Flasche einerseits und Isoliervorrichtung andererseits kaum Luft befindet, kann diese kalte Luft auch nicht herausfließen, durch warme Luft ersetzt werden und dadurch das Getränk erwärmen. Dies gilt erst recht aufgrund der Tatsache, daß zumindest auf einer Seite ein Deckel vorgesehen ist.Since there is hardly any air between the can or bottle on the one hand and the insulating device on the other hand, this cold air cannot flow out, be replaced by warm air and thereby heat the drink. This is all the more true due to the fact that a cover is provided on at least one side.

Eine besonders einfache Ausführungsform erhält man, wenn die Bodenöffnung deckelfrei ist. Es können dabei wie auch bei anderen Ausführungsformen in der Nähe des Bodenrandes Vorsprünge vorgesehen sein, damit die Flasche oder Dose nicht nach unten herausfallen kann. Sie wird vielmehr von oben, nachdem dort der Deckel geöffnet oder entfernt ist, in die Isoliervorrichtung hineingeschoben. Anschließend wird der Deckel geschlossen. Die Dose oder Flasche bleibt fest in der Isoliervorrichtung sitzen, da sie wie erwähnt ungefähr gleichen Außendurchmesser wie der Innendurchmesser der Isoliervorrichtung aufweist.A particularly simple embodiment is obtained when the bottom opening is lid-free. As in other embodiments, projections can be provided in the vicinity of the bottom edge so that the bottle or can cannot fall out downwards. Rather, it is pushed into the insulating device from above after the cover is opened or removed there. The lid is then closed. The can or bottle remains firmly in place in the isolating device as it is approximately as mentioned has the same outer diameter as the inner diameter of the insulating device.

Will man aus der Dose oder Flasche trinken oder das Getränk ausgießen, so übt man durch die Bodenöffnung Druck auf die Dose bzw. die Flasche aus, die sich dadurch nach oben bewegt und dabei den Deckel öffnet, falls dieser nicht, wie dies bei einigen Ausführungsformen zweckmäßig sein kann, vorher geöffnet oder entfernt wurde.If you want to drink from the can or bottle or pour out the drink, you put pressure on the can or bottle through the bottom opening, which moves upwards and thereby opens the lid, if not, as in some embodiments may be appropriate, previously opened or removed.

Anschließend kann nach Entnahme des Getränks die Dose oder Flasche wieder zurückgeschoben werden.The can or bottle can then be pushed back after the beverage has been removed.

Die Dose oder Flasche ist am Boden besser isoliert, wenn die Bodenöffnung einen am Rand schwenkbar befestigten Deckel aufweist. Dieser Deckel kann noch durch Vorsprünge im Bodenbereich daran gehindert werden, daß er sich nach außen öffnet. Das Einführen der Dose oder Flasche geschieht genau wie eben beschrieben. Das Herausdrücken nach oben geschieht dadurch, daß man auf den Bodendeckel an der Stelle einen Druck ausübt, die der schwenkbaren Befestigung gegenüberliegt. Zu diesem Zweck kann der Bodendeckel mit Markierungen, insbesondere Farbmarkierungen versehen sein.The can or bottle is better insulated at the bottom if the bottom opening has a lid that is pivotally attached to the edge. This cover can be prevented by projections in the bottom area that it opens outwards. The can or bottle is inserted exactly as described above. The pushing up is done by exerting pressure on the bottom cover at the point opposite the pivotable attachment. For this purpose, the bottom cover can be provided with markings, in particular color markings.

Eine andere Art, die Bodenöffnung zu verschließen, besteht darin, daß die Bodenöffnung von einem festen Deckel mit einem Mittelloch verschlossen ist und innerhalb der Isoliervorrichtung oberhalb des festen Deckels ein in Längsrichtung kolbenartig verschiebbarer weiterer Deckel vorgesehen ist.Another way of closing the bottom opening is that the bottom opening is closed by a fixed cover with a central hole and a further cover which can be displaced in the piston-like manner in the longitudinal direction is provided within the insulating device above the fixed cover.

Der Innenraum der Isoliervorrichtung ist auf diese Weise von dem kolbenartig verschiebbaren weiteren Deckel unten hermetisch verschlossen, so daß keinerlei Warmluft in den Bereich der Dose oder Flasche gelangt, wenn man durch das Mittelloch den kolbenartig verschiebbaren Deckel nach oben schiebt, um die Dose oder Flasche nach oben zu schieben, so daß Getränk entnommen werden kann. Wird anschließend auf die Dose oder Flasche Druck von oben ausgeübt, so wird der kolbenartige Deckel wieder nach unten geschoben.The interior of the insulating device is thus hermetically sealed at the bottom by the piston-like sliding lid so that no warm air gets into the area of the can or bottle when the piston-like sliding lid is pushed upward through the center hole to follow the can or bottle to slide up so that drink can be removed. Then on the can or Bottle pressure exerted from above, the piston-like lid is pushed back down.

Alle diese Ausführungsformen haben den Vorteil, daß die Deckel nicht verlorengehen können, da sie an der Isoliervorrichtung dauerhaft befestigt sind bzw. dauerhaft in derselben eingeschlossen sind. Man kann aber auch vorsehen, daß die Bodenöffnung einen Deckel in Form eines verhältnismäßig flachen Kolbens aufweist, der auf die Bodenöffnung aufgeschoben wird, wobei der kolbenartige Deckel einen vorstehenden Rand aufweist, so daß er nicht zu tief in die Isoliervorrichtung eingeschoben werden kann. Ähnliche kolbenartige Deckel kennt man z.B. bei Versandröhren für Zeichnungen, Plakate und dergleichen. Ein solcher kolbenartiger Deckel kann auch für die Oberseite der Isoliervorrichtung vorgesehen sein. Zweckmäßigerweise sind diese kolbenförmigen Deckel doppelwandig ausgebildet und in ihrer äußeren Wand mit einem Griffloch versehen.All of these embodiments have the advantage that the covers cannot be lost because they are permanently attached to the insulating device or are permanently enclosed therein. However, it can also be provided that the bottom opening has a cover in the form of a relatively flat piston which is pushed onto the bottom opening, the piston-like cover having a projecting edge so that it cannot be inserted too deeply into the insulating device. Similar piston-like covers are known e.g. for shipping tubes for drawings, posters and the like. Such a piston-like cover can also be provided for the top of the insulating device. These piston-shaped covers are expediently double-walled and provided with a grip hole in their outer wall.

Die obere Öffnung kann einen am Rand schwenkbar befestigten Deckel aufweisen, der dann ebenfalls nicht verlorengehen kann. Der Deckel kann mit einer Lasche an der Isoliervorrichtung befestigt sein oder aber im Falle einer Isoliervorrichtung mit rechteckigem Querschnitt oder einer Isoliervorrichtung, bei der wenigstens der obere Teil rechteckigen Querschnitt hat, an einer Seite dieses Rechtecks einstückig in den Hauptteil übergehen. Diese Art ist besonders für Flaschen geeignet, wobei dann der Deckel laschenartig ausgebildet ist und auf der der Befestigungsseite gegenüberliegenden Seite über den Flaschenhals hinweg in den Behälter eingesteckt werden kann.The upper opening can have a cover pivotally attached to the edge, which then cannot be lost either. The lid can be fastened to the insulating device with a tab or, in the case of an insulating device with a rectangular cross section or an insulating device in which at least the upper part has a rectangular cross section, merge integrally into the main part on one side of this rectangle. This type is particularly suitable for bottles, in which case the lid is designed in the manner of a tab and can be inserted into the container over the bottle neck on the side opposite the fastening side.

In den Fällen, in denen der Boden nicht die verhältnismäßig starre Konstruktion eines festen Deckels mit Mittelloch hat, kann die Isoliervorrichtung flach zusammengelegt werden. Bei schwenkbarem Boden wird dieser dafür zunächst in eine in die Isoliervorrichtung zeigende Schrägstellung gebracht, so daß er sich beim Zusammenfalten an die Wandungen anlegt. Der so zusammengelegte Behälter kann dann dauerhaft zusammengelegt werden, indem der obere Deckel auf die gegenüberliegende Seite, dieselbe umschließend, aufgelegt wird. Dort kann er dauerhaft festgehalten werden, wenn er innen mit einem selbstklebenden oder selbsthaftenden Element versehen ist, z.B. einem Klettverschluß. Normalerweise wird es aber zweckmäßig sein, die Isoliervorrichtung so auszubilden, daß sie vorher noch auf halbe Höhe gefaltet wird.In cases where the bottom does not have the relatively rigid construction of a fixed lid with a central hole, the insulating device can be folded flat. In the case of a pivotable base, this is first brought into an inclined position pointing into the insulating device, so that it lies against the walls when it is folded. The way collapsed containers can then be permanently collapsed by placing the top lid on the opposite side, enclosing it. It can be held there permanently if it is provided with a self-adhesive or self-adhesive element on the inside, for example a Velcro fastener. Normally, however, it will be useful to design the insulating device so that it is folded halfway up beforehand.

Für die obere Öffnung kann ein auf einer Stirnseite offener, verschieden weit auf die Isoliervorrichtung aufschiebbarer kolbenförmiger Deckel vorgesehen sein. Dieser kolbenförmige Deckel umschließt dabei den Hals einer Flasche. Je nach Größe der Flasche kann dieser kolbenförmige Deckel tiefer oder weniger tief in die eigentliche Isoliervorrichtung eingeschoben werden, so daß der Innenraum der Isoliervorrichtung möglichst klein ist.For the upper opening, a piston-shaped cover which is open on one end face and can be pushed onto the insulating device to different extents can be provided. This piston-shaped lid encloses the neck of a bottle. Depending on the size of the bottle, this piston-shaped lid can be pushed deeper or less deeply into the actual insulation device, so that the interior of the insulation device is as small as possible.

Die Erfindung kann Anwendung finden, um Getränke in Dosen und Flaschen kühl zu halten, wobei die Flaschen unterschiedliche Form haben können, da die Form der Isoliervorrichtung an die Flaschenform angepaßt werden kann. Eine besonders vorteilhafte Ausführungsform zeichnet sich dabei dadurch aus, daß gleichzeitig mehrere Flaschen, insbesondere aber Dosen aufeinanderstehend aufgenommen werden können. Zu diesem Zweck werden zweckmäßigerweise für das Verschließen an beiden Enden die kolbenartigen Deckel verwendet. Nachdem die Isoliervorrichtung geschlossen ist, können Dosen nicht ohne weiteres daraus entnommen werden, da die Dosen sehr eng in der Isoliervorrichtung sitzen. Dies ist nur dadurch möglich, indem von einer Seite, insbesondere von unten eine weitere Dose eingeschoben wird. Aufgrund dieser Wirkung ist dann der Benutzer gezwungen, gebrauchte Dosen nicht wegzuwerfen, sondern diese wieder in die Isoliervorrichtung einzuschieben. Mit der Vorrichtung werden die Getränke dadurch nicht nur gut kühl gehalten. Es wird vielmehr auch ein wirksamer Beitrag zum Umweltschutz geleistet.The invention can be used to keep drinks in cans and bottles cool, the bottles having different shapes, since the shape of the insulating device can be adapted to the shape of the bottle. A particularly advantageous embodiment is characterized in that several bottles, but in particular cans, can be accommodated one above the other at the same time. For this purpose, the piston-like cover is expediently used for closing at both ends. After the insulation device is closed, cans cannot be removed from it easily since the cans sit very closely in the insulation device. This is only possible by inserting another can from one side, especially from below. Because of this effect, the user is then forced not to throw away used cans, but to push them back into the insulating device. The device not only keeps the drinks well cool. Rather, it also makes an effective contribution to environmental protection.

Die Isoliervorrichtung ist im wesentlichen zylindrisch mit einer Zylinderwand 2 ausgebildet, die aus Pappe, Papier oder ähnlichen Materialien besteht und auf beiden Seiten mit einer Metallschicht versehen ist, insbesondere einer Aluminiumbeschichtung. Der Innendurchmesser des Zylinders 2 ist dabei ungefähr gleich groß wie der Außendurchmesser der Dose oder Flasche 1, so daß diese fest im Zylinder 2 sitzt. Die Dose wird in den Zylinder 2 eingeschoben, nachdem der Deckel 3 geöffnet worden ist. Dieser Deckel 3 ist mit einer Lasche 4 am Zylinder 2 befestigt, wobei diese Lasche entweder über den Rand des Zylinders 2 herausstehen kann, wie dies in der Figur gezeigt ist, oder aber innerhalb des Zylinders angeordnet sein kann. Damit die Dose beim Hereinschieben nicht unten wieder austreten kann, weist der Zylinder 2 innen eine Randerhöhung 5 auf, an der ein Deckel 6 für die Bodenöffnung angelascht ist. Die Randverstärkung 5 kann aber auch an anderen Orten vorgesehen sein. Der Bodendeckel 6 wiederum wirkt auf der der Befestigungsstelle 5 gegenüberliegenden Seite mit einem Vorsprung 7 zusammen, so daß er sich nicht nach außen öffnen kann. Nach dem Einfügen der Dose oder Flasche 1 wird der Deckel 3 geschlossen.1 to 5 show an embodiment of the insulating device of the invention, which is intended for receiving a can or bottle 1. The insulating device is essentially cylindrical with a cylinder wall 2, which consists of cardboard, paper or similar materials and is provided on both sides with a metal layer, in particular an aluminum coating. The inner diameter of the cylinder 2 is approximately the same size as the outer diameter of the can or bottle 1, so that it sits firmly in the cylinder 2. The can is inserted into the cylinder 2 after the lid 3 has been opened. This cover 3 is fastened to the cylinder 2 with a tab 4, which tab can either protrude beyond the edge of the cylinder 2, as shown in the figure, or inside of the cylinder can be arranged. So that the can cannot come out again at the bottom when it is pushed in, the cylinder 2 has a raised edge 5 on the inside, to which a lid 6 for the bottom opening is attached. The edge reinforcement 5 can also be provided at other locations. The bottom cover 6 in turn interacts with a projection 7 on the side opposite the attachment point 5, so that it cannot open outwards. After inserting the can or bottle 1, the lid 3 is closed.

Will man die Dose oder Flasche entnehmen oder daraus trinken, so drückt man auf den Deckel 6, und zwar insbesondere an einer Stelle, die durch den Pfeil 20 gekennzeichnet ist. Diese Stelle kann auch farbig markiert sein. Die Dose 1 wird dadurch nach oben gedrückt und öffnet den Deckel 3.If you want to remove or drink the can or bottle, you press on the lid 6, in particular at a point which is indicated by the arrow 20. This position can also be marked in color. The can 1 is thereby pushed upwards and opens the lid 3.

Nach dem Entnehmen der Dose oder Flasche 1 kann die Vorrichtung 2 zur Aufbewahrung oder zum Transport zusammengefaltet werden, damit man sie immer mit sich z.B. in der Hemdtasche herumtragen kann. Zu diesem Zweck wird der untere Deckel 6 ein wenig nach innen gedrückt, falls er sich nicht von selbst in diese Stellung legt. Dies ist in Fig. 2 gezeigt.After the can or bottle 1 has been removed, the device 2 can be folded up for storage or transport so that it can always be carried with you, e.g. can carry around in the shirt pocket. For this purpose, the lower cover 6 is pressed a little inward, if it does not put itself into this position. This is shown in Figure 2.

Der Behälter wird dann flachgedrückt, wie dies in Fig. 3 gezeigt ist. Anschließend wird der Behälter dann in halber Höhe noch einmal geknickt und in Richtung des Pfeiles 8 herumgeschwenkt, wobei dann anschließend der obere Deckel 3 in Richtung des Pfeiles 9 um das so gebildete Paket herumgelegt wird. Dabei kommt dann ein selbstklebender Streifen 10 (z.B. ein Klettverschluß oder ein Selbstklebeband) auf der gegenüberliegenden Außenwand zu liegen, wo das entsprechende Element 11 eines Klettverschlusses vorhanden ist, wenn ein Klettverschluß gewählt wird. Auf diese Weise wird das Paket dann fest in der Stellung zusammengehalten, die in Fig. 5 gezeigt ist.The container is then flattened as shown in FIG. 3. The container is then folded halfway up again and pivoted in the direction of arrow 8, the upper lid 3 then being placed around the package formed in the direction of arrow 9. A self-adhesive strip 10 (for example a Velcro fastener or a self-adhesive tape) then lies on the opposite outer wall, where the corresponding element 11 of a Velcro fastener is present when a Velcro fastener is selected. In this way, the package is then held firmly in the position shown in FIG. 5.

In der Ausführungsform der Fig. 6 ist ein anderer Bodendeckel gezeigt, der allerdings auch für die obere Öffnung verwendet werden kann. Der Bodendeckel besteht hierbei aus einem flachen Kolben 12, der am Rand mit einem Vorsprung 13 versehen ist, damit er nicht beliebig weit in den Zylinder 2 eingeschoben werden kann, obwohl dies bei der Ausführungsform der Fig. 6 auch durch den Vorsprung 5 verhindert werden würde. Solche Vorsprünge 5 wird man aber in vielen Fällen nicht vorsehen, und zwar insbesondere in dem Fall nicht, wo von einer Seite immer neue Dosen bzw. leere Dosen nachgeschoben werden sollen, um auf der anderen Seite gefüllte Dosen entnehmen zu können. Der Deckel 12 ist doppelwandig und hohl und weist in der Mitte in der äußeren Wandung ein Griffloch 14 auf, damit man hier mit dem Finger hereinfassen und den Deckel 12 entfernen kann.Another bottom cover is shown in the embodiment of FIG. 6, which, however, can also be used for the upper opening. The bottom cover here consists of a flat piston 12, which is provided on the edge with a projection 13 so that it cannot be inserted into the cylinder 2 as far as desired, although this would also be prevented by the projection 5 in the embodiment of FIG. 6 . In many cases, however, such projections 5 will not be provided, in particular not in the case where new cans or empty cans are to be added from one side in order to be able to remove filled cans on the other side. The lid 12 is double-walled and hollow and has a grip hole 14 in the middle in the outer wall so that you can reach in with your finger and remove the lid 12.

In der Ausführungsform der Fig. 7 ist einerseits eine andere Ausbildung des Bodendeckels gezeigt. Der Boden weist hier eine starr mit dem Zylinder 2 verbundene Stirnfläche 15 auf, die ein Mittelloch 16 besitzt. Durch dieses Mittelloch 16 kann man hineingreifen, um einen kolbenartig bewegbaren Deckel 17 und damit eine Flasche 18 nach oben schieben zu können. Es gelangt dabei, auch wenn die Flasche 18 nach oben geschoben wird, keine Luft zwischen kolbenartigen Deckel 17 und Flasche 18, so daß die Flasche gut kalt gehalten wird. Oben ist der Zylinder 2 mit einem nach unten offenen kolbenartigen Deckel 19 verschlossen, der den Flaschenhals der Flasche 18 umgreift. Dieser Deckel 19 kann je nach Flaschengröße verschieden weit in den Zylinder 2 hineingeschoben werden, so daß er immer auf der Flasche aufliegt und sich die Flasche nicht bewegen kann.Another embodiment of the bottom cover is shown in the embodiment of FIG. 7. The bottom here has an end face 15 which is rigidly connected to the cylinder 2 and has a central hole 16. Through this center hole 16 one can reach in to push a piston-like movable lid 17 and thus a bottle 18 upwards. There is no air between the piston-like lid 17 and bottle 18, even if the bottle 18 is pushed upwards, so that the bottle is kept well cold. The cylinder 2 is closed at the top with a piston-like cover 19 which is open at the bottom and which engages around the bottle neck of the bottle 18. Depending on the bottle size, this lid 19 can be pushed into the cylinder 2 to different degrees, so that it always rests on the bottle and the bottle cannot move.

Bei der Ausführungsform der Fig. 8 ist die Stirnfläche 15 des Bodens zu einem Wulst 15 reduziert; das Mittelloch 16 nimmt also fast die ganze Stirnfläche ein. Der kolbenartige Deckel 17 kann in Richtung des Doppelpfeiles bis in die unterste gestrichelt gezeigte Stellung verschoben werden.In the embodiment of FIG. 8, the end face 15 of the base is reduced to a bead 15; the center hole 16 thus takes up almost the entire end face. The piston-like cover 17 can be moved in the direction of the double arrow into the bottom position shown in dashed lines.

Der Zylinder 2 ist wie erwähnt der Form der Dose oder Flasche angepaßt. Falls die Flasche rechteckigen, quadratischen, oder sonstigen polygonalen Querschnitt hat, so tritt an Stelle des Zylinders 2 ein Element mit entsprechendem rechteckigen, quadratischen oder polygonalen Querschnitt. Es ist auch möglich, für Flaschen zwar den unteren Bereich zylinderförmig auszubilden, im oberen Bereich die Isoliervorrichtung aber mit einem quadratischen Querschnitt zu versehen, wobei der quadratische Querschnitt gleiche Umfangslänge aufweist. Wird die Flasche von oben hereingeschoben, so deformiert sich der obere Bereich mit quadratischem Querschnitt ebenfalls zu einem Zylinder um anschließend wieder die Form mit quadratischem Querschnitt einzunehmen. Der Deckel kann dann in Form einer Lasche ausgebildet sein, die vollständig an einer Quadratseite mit der eigentlichen Isoliervorrichtung verbunden ist und laschenartig auf der gegenüberliegenden Seite zwischen Wand und Flaschenhals eingesteckt werden kann, um die Isoliervorrichtung zu schließen.As mentioned, the cylinder 2 is adapted to the shape of the can or bottle. If the bottle has a rectangular, square or other polygonal cross-section, then an element with a corresponding rectangular, square or polygonal cross-section takes the place of the cylinder 2. It is also possible to make the lower area cylindrical for bottles, but to provide the insulating device in the upper area with a square cross-section, the square cross-section having the same circumferential length. If the bottle is pushed in from above, the upper area with a square cross section also deforms into a cylinder and then resumes the shape with a square cross section. The lid can then be designed in the form of a flap which is completely connected to the actual insulation device on one side of the square and can be inserted in the manner of a flap on the opposite side between the wall and the bottle neck in order to close the insulation device.
