Abstract

Bag for making ice cubes comprises two layers of plastic film joined together with seams (2, 3, 4) along three sides, where the two layers are folded down in the vicinity of a filling channel (6) on the fourth side to form a valve that closes when the bag is full and the bag is divided into interconnecting sections (8) by internal seams (7). The two layers can be separated from each other along at least some of the seams so that ice cubes can be removed.

Description

Die vorliegende Erfindung betrifft einen Beutel zur Herstellung von Eiswürfeln, mit zwei Lagen aus Kunststofffolie, die an drei Seiten zur Bildung eines Beutels miteinander über randseitig angeordnete Nahtstellen verbunden sind und an einer vierten Seite ein Einfüllkanal gebildet ist, wobei im Bereich des Einfüllkanals die zwei Lagen zur Bildung eines im befüllten Zustand des Beutels verschlossenen Ventils jeweils nach innen umgeklappt sind, und der Innenraum des Beutels über mittlere Nahtstellen in mehrere miteinander verbundene Abteile unterteilt ist.The present invention relates to a bag for the production of ice cubes, with two layers of plastic film, which are connected on three sides to form a bag with each other via seams arranged at the edge and on a fourth side of a filling channel is formed, wherein in the region of the filling channel, the two layers are each folded inward to form a closed in the filled state of the bag valve, and the interior of the bag is divided over central seams into a plurality of interconnected compartments.

Aus der EP 248 817 ist eine Form zur Herstellung von Eiskugeln bekannt, die aus Kunststofffolie bestehen kann und einen Beutel mit mehreren teilweise voneinander getrennten Abteilungen besitzt. Der Beutel wird mit Wasser befüllt und nach dem Frieren des Wassers können die inneren Unterteilungen des Beutels voneinander gelöst werden, sodass die Eiswürfel leichter entnehmbar sind und auf einfache Weise eine Vielzahl von Eiswürfeln weiterverarbeitet werden können. Der gezeigte Eiskugelbeutel besitzt jedoch den Nachteil, dass das Einfüllen des Wassers und das Verschließen über Klemmen relativ aufwendig ist. Zudem kann die Dichtheit nicht sicher gewährleistet werden.From EP 248 817 a mold for the production of ice balls is known, which may consist of plastic film and has a bag with several partially separate departments. The bag is filled with water and after freezing the water, the inner partitions of the bag can be detached from each other, so that the ice cubes are easier to remove and easily a variety of ice cubes can be processed. However, the ice ball bag shown has the disadvantage that the filling of the water and the closing via terminals is relatively expensive. In addition, the tightness can not be guaranteed safe.

Ferner ist aus der EP 616 948 ein Eiskugelbeutel bekannt, bei dem an einer Seite ein Ventilverschluss ausgebildet ist, der nach dem Befüllen des Beutels mit Wasser selbstständig schließt. Dafür ist an der Seite des Ventils die Folie zur Bildung des Beutels nach innen umgeklappt, sodass benachbart zu einem Einfüllkanal innere Taschen gebildet sind, die nach dem Befüllen den Einfüllkanal verschließen. Bei diesem Eiskugelbeutel ist jedoch nachteilig, dass das Entnehmen der Eiskugeln schlecht möglich ist und das einzelne Abreißen der Eiskugeln vergleichsweise aufwendig wird. Zudem kann es passieren, dass Folienreste an den Eiswürfeln verbleiben, die dann mit in ein Getränk gelangen können.Furthermore, EP 616 948 discloses an ice-ball bag in which a valve closure is formed on one side and automatically closes with water after the bag has been filled. For this, on the side of the valve, the film for the formation of the bag is folded inwards, so that adjacent to a filling channel inner pockets are formed, which close the filling channel after filling. In this ice ball bag is disadvantageous, however, that the removal of the ice balls is poorly possible and the individual tearing of the ice balls is relatively expensive. In addition, it may happen that residues of film remain on the ice cubes, which can then enter into a drink.

Aus diesem Grund wird in der EP 927 859 vorgeschlagen, eine Punktschweißung im Innenbereich des Eiskugelbeutels vorzusehen, damit die Eiswürfel in einem Innenraum des Beutels gesammelt werden können. Aber auch durch eine solche durch Punktschweißung entstandene Perforierung wird der Eiskugelbeutel zerrissen und es können die oben erwähnten Probleme auftreten.For this reason, it is proposed in EP 927 859 to provide a spot weld in the interior of the ice bag so that the ice cubes can be collected in an interior of the bag. But even by such a result of spot welding perforation of the ice ball bag is torn and it can cause the above-mentioned problems.

Es ist daher Aufgabe der Erfindung einen Beutel zur Herstellung von Eiswürfeln zu schaffen, der einfach zu befüllen ist und bei dem sich die Eiswürfel auf einfache Weise entnehmen lassen.It is therefore an object of the invention to provide a bag for the production of ice cubes, which is easy to fill and in which the ice cubes can be easily removed.

Diese Aufgabe wird mit einem Beutel zur Herstellung von Eiswürfeln mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a bag for the production of ice cubes with the features of claim 1.

Erfindungsgemäß weist der Beutel ein selbstschließendes Ventil auf, das durch einen Einfüllkanal gebildet ist, bei dem die zwei Lagen der Kunststofffolie nach innen umgeklappt sind, sodass sich Taschen bilden, die im befüllten Zustand den Einfüllkanal verschließen. So lässt sich der Beutel leicht befüllen. Zudem sind die beiden Lagen zumindest an einem Teil der Nahtstellen voneinander lösbar, ohne dass die Lagen beschädigt werden. Dadurch können die Eiswürfel aus einem geöffneten Bereich mit getrennten Lagen auf einfache Weise entnommen werden, ohne dass die Folienlagen beschädigt werden und Folienreste an den Eiswürfeln kleben bleiben können. Die Nahtstellen in den lösbaren Bereichen können durch Schweißen, Kleben oder andere Verbindungstechniken hergestellt sein, wie sie insbesondere auch im Verpackungsbereich bekannt sind. Durch die Möglichkeit des Öffnens der Beutel durch Trennen der Lagen wird die Handhabung wesentlich vereinfacht.According to the invention, the bag has a self-closing valve, which is formed by a filling channel, in which the two layers of the plastic film are folded inwards, so that form pockets that close the filling channel in the filled state. This makes it easy to fill the bag. In addition, the two layers are detachable from each other at least at a part of the seams, without the layers are damaged. As a result, the ice cubes can be removed from an open area with separate layers in a simple manner, without the film layers are damaged and residual film can stick to the ice cubes. The seams in the releasable areas may be made by welding, gluing or other joining techniques such as especially in the packaging sector are known. The possibility of opening the bag by separating the layers handling is much easier.

Gemäß einer bevorzugten Ausgestaltung der Erfindung besitzen die Nahtstellen in dem umgeklappten Bereich mit vier Lagen eine höhere Festigkeit als die Nahtstellen im Bereich mit zwei Lagen. Im umgeklappten Bereich ist der Beutel vierlagig aufgebaut und der Einfüllkanal mit den Taschen ist dort vorgesehen. Wenn hier die Nahtstellen eine höhere Festigkeit besitzen, wird verhindert, dass beim Befüllen des Beutels die Nahtstellen an dem Einfüllkanal beschädigt werden, was zu Undichtigkeiten führen könnte. Denn wenn die Nahtstellen lösbar ausgebildet sind, besteht natürlich auch die Gefahr, dass schon beim Befüllen des Beutels die Lagen voneinander getrennt werden und somit der Beutel in seiner Funktion beeinträchtigt wird. Insofern ist es von Vorteil, wenn die Nahtstellen im umgeklappten Bereich, also dort, wo das selbstschließende Ventil angeordnet ist, eine höhere Festigkeit besitzen und nicht so leicht voneinander trennbar sind. Vorzugsweise sind die Nahtstellen im Bereich des Einfüllkanals so ausgebildet, dass die Lagen nur unter Beschädigung voneinander lösbar sind, also dass die Haltekräfte der Nahtstellen größer als die Reißfestigkeit der Lagen sind.According to a preferred embodiment of the invention, the seams in the folded-over area with four layers have a higher strength than the seams in the area with two layers. In the folded area, the bag has four layers and the filling channel with the pockets is provided there. If the seams here have a higher strength, it is prevented that when filling the bag, the seams are damaged at the filling channel, which could lead to leaks. Because if the seams are detachably formed, of course, there is also the danger that even when filling the bag, the layers are separated from each other and thus the bag is impaired in its function. In this respect, it is advantageous if the seams in the folded area, ie where the self-closing valve is arranged, have a higher strength and are not so easy to separate from each other. Preferably, the seams are formed in the region of the filling channel so that the layers are only mutually detachable under damage, so that the holding forces of the seams are greater than the tear strength of the layers.

Für eine einfache Herstellung des Beutels sind die Nahtstellen durch Verschweißen der Lagen gebildet. Dadurch lassen sich die Beutel auch gut im kontinuierlichen Verfahren herstellen.For a simple production of the bag, the seams are formed by welding the layers. As a result, the bags can also be produced well in a continuous process.

Gemäß einer weiteren Ausführungsform der Erfindung sind die Lagen des Beutels jeweils mehrschichtig aufgebaut, eine Lage umfasst also über den Querschnitt gesehen eine unterschiedliche Konsistenz. Eine Innenschicht der Lagen kann so beschaffen sein, dass bei einem Verschweißen von zwei Innenschichten eine lösbare Verbindung erhalten wird. "Innen" bezieht sich dabei auf die Innenfläche des Beutels, wobei in dem Bereich des Einfüllkanals die Lagen umgeklappt sind, sodass dort dann jeweils eine äußere Fläche der Lage innen angeordnet ist. Vorzugsweise ist eine äußere Fläche der Lagen jeweils so beschaffen, dass bei einem Verschweißen von zwei äußeren Schichten eine unlösbare Verbindung hergestellt wird. Dadurch kann mit einem einzigen Schweißschritt der Beutel mit Nahtstellen versehen werden, die einerseits zum Trennen der Lagen und Öffnen des Beutels voneinander lösbar sind, aber im Bereich des Einfüllkanals fest miteinander verbunden bleiben, sodass auch beim Befüllen des Beutels Stellen um den Einfüllkanal nicht beschädigt werden. Eine Beschichtung an der inneren Fläche und/oder der äußeren Fläche wird genutzt, um in einem einzigen Herstellungsschritt beim Schweißen Nahtstellen unterschiedlicher Festigkeit zu erhalten.According to a further embodiment of the invention, the layers of the bag are each constructed in a multi-layered manner, that is to say a layer comprises a different consistency seen over the cross section. An inner layer of the layers may be such that a releasable connection is obtained when welding two inner layers. "Inner" refers to the inner surface of the bag, wherein in the region of the filling channel, the layers are folded, so that there is then arranged in each case an outer surface of the layer inside. Preferably, an outer surface of the layers is in each case such that a non-detachable connection is produced when two outer layers are welded together. Thereby can be provided with a single welding step, the bag with seams, which are on the one hand for separating the layers and opening the bag detached from each other, but remain firmly connected to each other in the region of the filling channel, so that even when filling the bag locations around the filling channel are not damaged. A coating on the inner surface and / or the outer surface is used to obtain joints of different strength in a single manufacturing step during welding.

Vorzugsweise sind die Lagen jeweils dreischichtig mit einer mittleren Trägerschicht, einer Innenschicht und einer Außenschicht ausgebildet. Dabei kann die Kunststofffolie der Lagen koextrudiert im Blasverfahren oder als Flachfolie hergestellt sein.Preferably, the layers are each formed in three layers with a middle carrier layer, an inner layer and an outer layer. In this case, the plastic film of the layers can be coextruded by blow molding or produced as a flat film.

Bevorzugt ist eine umgeklappte Seite der Lagen außerhalb des Einfüllkanals durch Nahtstellen fixiert. Dadurch liegen die Seiten fixiert innerhalb des Beutels und durch die Breite der Nahtstellen können auch gewisse Toleranzen bei der Länge der umgeklappten Bereiche ausgeglichen werden.Preferably, a folded side of the layers outside of the filling channel is fixed by seams. As a result, the sides are fixed within the bag and by the width of the seams and certain tolerances in the length of the folded areas can be compensated.

Für ein leichtes Öffnen des Beutels ist die Nahtstelle an der zum Einfüllkanal gegenüberliegenden Seite zumindest teilweise beabstandet von einer Endkante der Lagen angeordnet, sodass Streifen und/oder Eckabschnitte gebildet sind, die von Hand leicht auseinander bewegt werden können. Diese Streifen bzw. Eckabschnitten können dann auseinandergezogen werden, um die Nahtstellen zu öffnen und die Eiswürfel zu entnehmen.For easy opening of the bag, the seam on the opposite side of the filling channel is at least partially spaced from an end edge of the layers, so that strips and / or corner portions are formed, which can be easily moved apart by hand. These strips or corner sections can then be pulled apart to open the seams and remove the ice cubes.

Ein Beutel 1 zur Herstellung von Eiswürfeln umfasst zwei Lagen aus Kunststofffolie, beispielsweise aus Polyethylen oder anderen Folienmaterialien. Der Begriff "Eiswürfel" oder "Eiskugel" soll nicht streng geometrisch verstanden werden sondern auch auf Körper Anwendung finden, die länglich, oval, dreiecksförmig oder eine andere Form besitzen, die im allgemeinen Sprachgebrauch noch mit "Eiswürfel" bezeichnet wird.A bag 1 for making ice cubes comprises two layers of plastic film, for example polyethylene or other film materials. The term "ice cube" or "ice ball" should not be understood strictly geometric but also apply to body, which have elongated, oval, triangular or other shape, which is still referred to in common usage with "ice cubes".

Der Beutel 1 ist im Wesentlichen rechteckig ausgebildet und umfasst an zwei Längsseiten Nahtstellen 2 und 3, die an einer Seite über eine Nahtstelle 4 miteinander verbunden sind. Zu der Seite mit der Nahtstelle 4 gegenüberliegend ist eine vierte Seite 5 vorgesehen, an der ein Einfüllkanal 6 angeordnet ist. Über den Einfüllkanal 6 kann ein Fluid in einen Innenraum des Beutels 1 gefüllt werden, wobei der Innenraum über mehrere mittlere Nahtstellen 7 in einzelne Abteile 8 unterteilt ist, die miteinander verbunden sind.The bag 1 is substantially rectangular and comprises at two longitudinal sides seams 2 and 3, which are connected to one another via a seam 4. To the side with the seam 4 opposite a fourth side 5 is provided, on which a filling channel 6 is arranged. Via the filling channel 6, a fluid can be filled into an interior of the bag 1, wherein the interior is divided over several middle seams 7 into individual compartments 8, which are interconnected.

Der Einfüllkanal 6 erstreckt sich nur über einen kleinen Teil der Länge der vierten Seite 5 und benachbart zu dem Einfüllkanal 6 sind Nahtstellen 9 vorgesehen.The filling channel 6 extends only over a small part of the length of the fourth side 5 and adjacent to the filling channel 6 seams 9 are provided.

Der Einfüllkanal 6 ist Bestandteil eines selbstschließenden Ventils und im Bereich des Einfüllkanals sind die Lagen aus Kunststofffolie umgeklappt, d.h. in diesem Bereich ist der Beutel 1 vierlagig statt zweilagig ausgebildet. Der Einfüllkanal 6 weist einen ersten Abschnitt 10 mit größerer Breite auf, der sich bis zu einer Einschnürung 11 erstreckt. Unterhalb der Einschnürung 11 ist ein zweiter Abschnitt 12 gebildet, der sich gegenüber der Einschnürung 11 wieder erweitert und an dessen Endbereich eine Kante 13 der umgeklappten Lage angeordnet ist. Dadurch wird beim Befüllen des Beutels 1 der Einfüllkanal 6 und die Abteilungen 8 gefüllt, wobei das Fluid hinter die umgeklappte Kante 13 gelangt und somit im Bereich des Einfüllkanals 6 Taschen ausgebildet werden, die den Einfüllkanal 6 nach dem Befüllen des Beutels 1 verschließen.The filling channel 6 is part of a self-closing valve and in the region of the filling channel, the layers of plastic film are folded, ie in this area the bag 1 is four-ply instead of two-ply. The filling channel 6 has a first portion 10 with a greater width, which extends to a constriction 11. Below the constriction 11, a second portion 12 is formed, which widens again against the constriction 11 and at the End region an edge 13 of the folded position is arranged. As a result, when filling the bag 1, the filling channel 6 and the compartments 8 are filled, wherein the fluid passes behind the folded edge 13 and thus pockets 6 are formed in the region of the filling channel 6 which close the filling channel 6 after filling the bag 1.

Der Einfüllkanal 6 ist etwa mittig angeordnet und benachbart sind Hohlkammern 14 gebildet, die jedoch umlaufend von Nahtstellen umgeben sind, sodass kein Fluid in diese Hohlkammern gelangen kann. An der zum mittleren Bereich gewandten Seite der Hohlkammern 14 ist eine Nahtstelle 18 vorgesehen, mittels der die Kante 13 der Schichten jeweils festgelegt ist. Dadurch liegen die Kanten 13 im nicht sichtbaren Bereich und sind zudem außerhalb des Einfüllkanals 6 fixiert gehalten.The filling channel 6 is arranged approximately centrally and adjacent hollow chambers 14 are formed, which are, however, circumferentially surrounded by seams, so that no fluid can get into these hollow chambers. On the side of the hollow chambers 14 facing the central region, a seam 18 is provided, by means of which the edge 13 of the layers is respectively fixed. As a result, the edges 13 are in the non-visible region and are also kept fixed outside of the filling channel 6.

Die beiden Folienlagen sind dreischichtig aufgebaut, wobei eine mittlere Trägerschicht an der Innenseite durch ein Polymer beschichtet ist und auch außen eine Beschichtung vorgesehen ist. Die Folie kann koextrudiert im Blasverfahren oder als Flachfolie hergestellt sein. Die Folie kann dabei relativ dünn und transparent ausgebildet sein, wobei Gebrauchshinweise aufgedruckt sein können. Die beiden Lagen des Beutels 1 können aus demselben Material gebildet sein.The two film layers are constructed in three layers, wherein a middle carrier layer is coated on the inside by a polymer and also outside a coating is provided. The film can be coextruded by blow molding or produced as a flat film. The film can be made relatively thin and transparent, with instructions for use can be printed. The two layers of the bag 1 may be formed of the same material.

Beim Herstellen werden zunächst die Lagen an der vierten Seite 5 umgeklappt und anschließend verschweißt. Beim Verschweißen werden Nahtstellen 2, 3, 4 und 7 gebildet, bei denen jeweils die Innenfläche der Lagen aufeinander aufliegen. An diesen Innenflächen ist das Material so beschaffen, dass diese nach dem Verschweißen lösbar sind, d.h. die beiden Lagen auseinandergezogen werden können, ohne dass die Lagen beschädigt werden. Dies erleichtert das Öffnen des Beutels 1. In dem Bereich mit den umgeklappten Lagen im Befüllkanal 6 liegt jeweils eine Außenfläche der Lage aufeinander auf und die Außenfläche ist so beschaffen, dass diese beim Verschweißen unlösbar miteinander verbunden wird, also die Kräfte zum Trennen der Schweißnaht größer sind als die Reißfestigkeit der Lage, sodass bei entsprechenden Trennkräften die Lage beschädigt wird, aber die Nahtstellen erhalten bleiben. Dadurch wird im Bereich des Einfüllkanals 6 eine stabile Geometrie der Nahtstellen erhalten, während in dem befüllten Bereich mit den Abteilungen 8 der Beutel 1 leicht zu öffnen ist.When manufacturing the layers are first folded on the fourth page 5 and then welded. When welding seams 2, 3, 4 and 7 are formed, in each case the inner surface of the layers rest on each other. At these inner surfaces of the material is such that they are solvable after welding, ie the two layers can be pulled apart without the layers are damaged. This facilitates the opening of the bag 1. In the area with the folded layers in the filling channel 6 each have an outer surface of the layer on each other and the outer surface is such that it is inextricably linked during welding, so the forces to separate the weld larger are known as the tear strength of the layer so that with appropriate release forces the layer will be damaged but the seams will be preserved. As a result, in the region of the filling channel 6 a stable geometry the seams, while in the filled area with the compartments 8 the bag 1 is easy to open.

An der zum Einfüllkanal 6 gegenüberliegenden Seite ist die Nahtstelle 4 von einer Kante der Lagen beabstandet angeordnet, sodass sich ein Streifen bzw. Eckabschnitt 15 ausbildet. Dieser Streifen bzw. Eckabschnitt kann von Hand leicht gegriffen werden und anfangs das Öffnen des Beutels 1 erleichtern.At the opposite side of the filling channel 6, the seam 4 is spaced from one edge of the layers, so that a strip or corner portion 15 is formed. This strip or corner portion can be easily grasped by hand and initially facilitate the opening of the bag 1.

In Figur 2 ist eine modifizierte Ausführungsform zweier Beutel 1' gezeigt, die an ihren Längsseiten über eine Perforation 20 miteinander verbunden sind. Dadurch können mehrere Beutel 1 ' auf eine Rolle aufgewickelt werden und als Verpackungseinheit vertrieben werden. Der Beutel 1' umfasst einen modifizierten Einfüllkanal 6', bei dem sich der Einfüllkanal 6' zunächst stärker verjüngt und anfangs breiter ist. Der innere Bereich der Beutel 1' ist durch im Wesentlichen dreieckförmige Abteilungen 8' gebildet, die durch mittlere Nahtstellen 7' voneinander getrennt sind. Im Übrigen ist der Beutel 1' wie beim ersten Ausführungsbeispiel ausgebildet.FIG. 2 shows a modified embodiment of two bags 1 ', which are connected to each other at their longitudinal sides via a perforation 20. As a result, several bags 1 'can be wound onto a roll and sold as a packaging unit. The bag 1 'comprises a modified filling channel 6', in which the filling channel 6 'initially tapers more strongly and initially is wider. The inner region of the bags 1 'is formed by substantially triangular sections 8', which are separated from one another by central seams 7 '. Incidentally, the bag 1 'is formed as in the first embodiment.

Bei dem in Figur 3 gezeigten Ausführungsbeispiel sind die Beutel 1" wieder über eine Perforation 20 miteinander verbunden, sodass diese durch ein kontinuierliches Herstellungsverfahren von randförmigem Material herstellbar sind. Bei dem Beutel 1 " ist der Einfüllkanal 6" modifiziert, wobei die Einschnürung eine U-förmige Nahtstelle aufweist. Die Abteilungen 8 sind wiederum rund ausgebildet.3, the bags 1 "are again connected to one another via a perforation 20 so that they can be produced by a continuous production process of edge-shaped material. The sections 8 are again round.

Bei dem in Figur 4 gezeigten Ausführungsbeispiel eines Beutels 1"' sind die inneren Abteilungen 8" im Wesentlichen quadratisch ausgebildet, wobei die Abteilungen 8''' miteinander verbunden sind. Der Einfüllkanal 6" ist bei diesem Ausführungsbeispiel keilförmig zulaufend mit einer mittleren Einschnürung ausgebildet.In the embodiment of a bag 1 "'shown in FIG. 4, the inner compartments 8" are substantially square, with the compartments 8' "connected to one another. The filling channel 6 "is formed in this embodiment wedge-shaped tapering with a central constriction.

In Figur 5 ist ein befüllter Beutel 1 beim Öffnen dargestellt. Durch den Streifen bzw. Eckabschnitt 15 auf der zum Einfüllkanal 6 gegenüberliegenden Seite können Lagen 16 und 17 gut gegriffen werden und die Nahtstellen 2, 3, 4 und 7 können voneinander durch Zugkräfte gelöst werden. Dadurch werden die in dem inneren Bereich des Beutels 1 befindlichen Eiswürfel entnehmbar, wobei durch das Lösen der Nahtstellen 2, 3, 4 und 7 verhindert wird, dass die Lagen 16 und 17 beschädigt werden und Folienreste an den Eiswürfeln verbleiben.FIG. 5 shows a filled bag 1 during opening. By the strip or corner portion 15 on the opposite side of the filling channel 6 layers 16 and 17 can be easily grasped and the seams 2, 3, 4 and 7 can be released from each other by tensile forces. This will be the inside Removing the seams 2, 3, 4 and 7 prevents the layers 16 and 17 are damaged and remain film residues on the ice cubes.

Bei den dargestellten Ausführungsformen ist der Einfüllkanal 6 jeweils durch zwei Abteilungen gebildet, die über eine Einschnürung voneinander getrennt sind. Auch andere Kanäle können vorgesehen sein, die die Funktion eines selbstschließenden Ventils erfüllen. Der umgeklappte Bereich muss sich auch nicht vollständig über den gesamten Einfüllkanal erstrecken, sondern es ist möglich, den umgeklappten Bereich etwas schmaler auszubilden, so dass die Kante 13 etwas weiter am Rand liegt.In the illustrated embodiments, the filling channel 6 is formed in each case by two departments, which are separated by a constriction. Other channels may be provided which fulfill the function of a self-closing valve. The folded-over area also does not have to extend completely over the entire filling channel, but it is possible to make the folded-over area somewhat narrower so that the edge 13 lies somewhat further at the edge.

Auch die Form der Abteilungen 8 des Beutels 1 kann relativ frei gewählt werden, um Eiskörper unterschiedlicher Geometrie herzustellen.The shape of the compartments 8 of the bag 1 can be chosen relatively freely to produce ice bodies of different geometry.
