The container comprises a withdrawal opening with a bent opening edge and is closed at its end opposite the withdrawal opening. At least the container wall is formed from a two-dimensional blank which is connected with itself for forming a continuous container wall. To improve such a container that in a simple constructive and inexpensive manner an inspection of the interior is possible and all advantages of the known containers are maintained, the container and in particular the container wall are at least partially formed from a transparent or translucent, in particular a liquid or fluid tight material which can be shaped for forming the container and which is dimensionally stable after having been shaped. Also, blank for the manufacturer of such a container is provided.

Description

E N V A S E The invention relates to a container, for receiving food, having the characteristics of claim 1, as well as a corresponding preform for manufacturing this container. In practice, these containers are known, for example, in the form of cups or similar, which are filled with food, which are stored and then removed or, alternatively, are consumed directly from the container. An example for a collapsible container is known from EP 0 074 936 Bl. This collapsible container comprises a tubular body with a wall made of at least two layers. At the upper end, a removal opening serves to fill the food, as well as to consume this filled food. At the lower end, the collapsible container is closed. For the manufacture of the container, a two-dimensional preform is used, which is first rolled and then connected to itself to form a continuous wall of the container. The material of the wall is a relatively flexible and relatively rigid material, such as paper or waterproof plastics. However, with this known container, one can not identify when the container is filled with something, and, if so, with what. From the Japanese Utility Model Publication 56-155777, another container is known, which also serves to receive food. This container is formed of a rigid paper laminate and polyethylene layers applied on both sides. A cover to close the container consists of a laminate of aluminum foil and polyethylene layers applied on both sides. This container is opaque and thus the interior of the container is not optically visible. The main object of the invention is to improve a package, having the characteristics of the preamble of claim 1, in which, in a simple and inexpensive construction, it is possible to make an inspection inside the package, and keep all the advantages of the known containers. This object is achieved by the features of claim 1. In accordance with the invention, a corresponding preform is provided for the manufacture of such a container. This foldable package, according to the invention, is characterized by the use of a material for at least part of the container wall, which apparently combines the conflicting properties in an advantageous manner. In order to safely store the food in the package, the material, according to the invention, is preferably liquid tight or fluid tight. This prevents both the penetration and the escape of the liquid fluids and / or the penetration and escape of the gaseous fluids. In the case of dry food, in particular that can be emptied, the gas-tight form may be sufficient in this respect. One can also manufacture it without being gas-tight, if the food does not negatively change its corresponding properties for consumption, when it comes into contact with a gas, such as 02, or the like. Simultaneously, the material is transparent. This results in a number of advantages, for example, that, after manufacture of the package, from the corresponding preform, one can simply identify, in visual form, whether the interior of the package contains foreign substances and, in particular, impurities, or if it is damaged. This optical transparency of the collapsible container exists at least in the visible region (translucent) spectrum, however, it can also extend to the adjacent spectral regions, ie at least to the infrared and / or ultraviolet region. The optical transparency also makes it possible to monitor the degree of filling of the corresponding food when it is filled. In particular, the degree of filling can be monitored from a direction perpendicular to the filling direction. The transparency of the material also includes, apart from the advantages of filling the foldable container, a number of advantages for the consumer who wishes to take the corresponding food out of the container or consume it directly from this container. For the consumer, also, it is important to be able to identify the degree of filling of the food, in a simple way. Also, apart from the quantity, the consistency of the filled food can be identified. This is true analogously for possible discolorations or colorations of the food. These discolorations can, for example, allow conclusions of the freshness of the food and the attempted colorations of the food can give an additional optical incentive for its purchase. Another advantage of the transparency of the material is that, during consumption, one can not identify through the removal opening where the food is located, in relation to the removal opening, but one can also discover it through the wall of the container. This, for example, prevents that, in the case of tipping the container, the food comes out unintentionally from the removal opening. In principle, it is sufficient that only a part of the wall of the container is formed of a transparent or translucent material and preferably fluid-tight and / or fluid-tight. The remaining part of the container wall can be formed in the usual manner of paper made rigid or the like. However, according to the invention it is a great advantage to form the wall of the complete container of this material, so that at each location, the interior of the container can be identified through the wall of the container. This makes it superfluous to first rotate the container, if necessary, in order to find the transparent section of the container wall. However, if the container wall is only transparent / translucent in one section, it extends favorably through the full height of the filled food, to allow an observation of the maximum degree of filling, as well as a reduction in the degree of filling during consumption. To do this, it may be sufficient that the container wall comprises a series of sections of the corresponding material, along the height of the filled food, which may also be spaced in the longitudinal direction of the container and, if necessary, also in the circumferential direction of the container. As a corresponding material, polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyamide (PA), polyethylene terephthalate PT), polyester or the like, can be used. In order to improve the airtightness of the corresponding layer material, if necessary, the layer can be provided with a coating of lacquer on one or both sides. In order for the consumer to be able to exert pressure on the package to consume the food, the wall of this package can be flexible. This also goes for the fluid-tight material, preferably the corresponding transparent or translucent liquid. In order to make it possible to connect the preform to itself, in order to prepare the continuous wall of the container, it can be rolled, for example, until the lateral edges are reached. Together with this edge stop, the preform connects with itself. An additional connection element can also be used, if necessary. Normally, this kind of connection is made by heat and / or pressure. It is also possible not only to form a connection along the corresponding edge stop, after the package has been rolled or bent, but also to form a region of overlap of the preform by the edges assigned to each other, this region of overlap extends in particular in the longitudinal direction of the container and the preform connects with itself in this overlapping region. If the transparent and fluid-tight material extends to the upper end of the corresponding preform, where the removal opening of the finished package is formed, or if a container wall is made entirely of this material, the opening edge of the opening of the Removal can be bent or rolled without the corresponding material changing its properties. Thus, it is ensured that even the opening edge comprises the properties of the material, such as transparency, fluid tightness and dimensional stability. Since the corresponding material is dimensionally stable after it has been configured, it is ensured that the opening edge maintains its corresponding configuration, even after it has been bent or turned round. Also, the configurability without the material changing its properties serves to avoid, for example, the so-called crack formation. It occurs, for example, in materials that are transparent at the beginning, which, however, comprise a normally linear bleaching of the material, otherwise it remains transparent, after it has been configured or bent. Such cracks may, otherwise, also occur in areas of the wall where a consumer holds the container or exerts a corresponding pressure to remove the food, which can result in bending or buckling lines. Even if such changes of the properties are partially acceptable, for example, at the edge of the opening, they are advantageously avoided in particular. In particular, if the wall of the complete container of the material is formed, the entire container is not only liquid / fluid tight and transparent / translucent correspondingly, but is also dimensionally stable, after it has been configured. This dimensional stability is, among other things, important when the container is stored or transported between the place of manufacture and the place of filling. Also, the container remains open at least in the area of its removal opening, when it is filled, due to a corresponding dimensional stability, even if additional measures, so that the food can be easily filled. The dimensional stability is also helpful when the food is consumed, the container itself maintains its configuration even after the food has been removed, partially or completely. If the package is compressed by exerting pressure to consume the food, the dimensional stability is of assistance so that the package essentially takes its original configuration, after the pressure has stopped, which results in the food being retracted back into the interior of the container. container. Dimensional stability is also a property which will not be changed, for example, . maintaining a sufficient stability as well as a transparency and airtightness also in the region of the overlap. In order to be able to combine, if necessary, the layers having different properties, with respect to transparency and fluid tightness, the container wall can be formed of a corresponding two or multiple layer material, each of the layers being transparent. It should be noted here that "transparency" can also mean only translucent and the fluid tightness can also mean only liquid tightness or gas tightness, and should always be understood in this regard. An outer layer can be made in this ratio of PP, PP oriented (co-extruded or lacquered), PE, PET, lacquered PET, PA, PA oriented (lacquered) or the like. For the inner layer, the following materials are possible: PP, PVC, PS, PA, PET, or similar. With respect to the various layers, it is advantageous that they are, for example, laminated. A large laminated detail surface can be obtained from the corresponding layers and a preform can then be die cut from the laminate or prepared in another way. The use of such a laminate ensures the interconnection of the layers at the same time maintaining the corresponding properties. Another possibility of preparing and interconnecting the layers may be co-extrusion. In order to be able to employ in a simple manner a corresponding preform for the container, also for devices in the manufacture as well as in the filling, hitherto employed for similar containers, the preform not configured can strictly be two-dimensional. This makes it possible, on the one hand, to easily stack these preforms for transport and, on the other hand, simply to propel them into a corresponding device for folding or rolling the package from the preform. In this aspect, it is also advantageous for at least the outer sides of the preform to comprise a certain roughness or basic friction, which, for example, prevents a slippage of the corresponding impulse element relative to the preform. During transport of the container, both in the unfilled and already filled state and the provision of a full folded container or its use by a consumer, it is possible that the folded container comes into contact with sharps or sharp objects. In this aspect, it is an advantage that the corresponding material of the container wall comprises some mechanical resistance to such objects, preventing damage that could have a negative influence or any of the transparency or the fluid tightness of the material. In order to avoid that during the manufacture of the container or its subsequent handling, particularly in the area of the wall, a negative optical impression occurs, with the construction of two or multiple layers of the material, the corresponding layers can be joined in one perfect permanent union. Otherwise, a detachment of the layers in some places could result in the printing of a bubble formation or the like, which could, apart from the optical impression, possibly have a negative influence on the transparency of the material. Examples of permanent perfect joints are lamination, described above, or co-extrusion. Regardless of the number of layers of the corresponding material, it is usually sufficient for one of the layers or the only layer used, in the case of several layers in particular the central layer, of an elastic material, which, however, can be permanently configured and it is a dimensionally stable layer after it has been configured. In order to achieve optimum fluid tightness, it can prove to be an advantage if the tightness to the liquid and to the gas is achieved by separate layers. This can be achieved, for example, in that at least one inner layer is airtight to the liquid and / or one of the subsequent layers is gas-tight. It is possible to combine the corresponding layers in the overlap region, by additional connection elements. such as an adhesive or the like. In a simplified embodiment, the external and / or internal layers can be forms as a connection layer in at least the overlap region. With respect to the material of the layers, it should be noted that, for example, one of the layers may comprise a function of heat insulation to cool or heat the food and / or it is also possible that all the layers are permeable to microwaves, for example to heat the food inside the container. Of course, there is also the possibility of achieving fluid tightness, ie towards liquids and gases, by only a single layer. In particular, in the region of overlap, but also in the region of the removal opening and its opening edge, as well as along other edges of the preform, sometimes a problem occurs that these edges or free ends of the corresponding material are not sealed sufficiently. Therefore, in particular the liquid ingredients of the food or the liquids placed on the outside of the collapsible container, such that the damming water can penetrate the material. Such penetration normally changes the thickness of the corresponding material or at least one layer of material, so that bubbles can form in the material and have a negative influence on the optical appearance. The penetration of such liquid by means of the free ends or edges of the layers, can also result in the container becoming weaker or losing some of its properties, such as dimensional stability. Such penetration is particular to the liquid and may also result in a soaking of the surface of the collapsible container and a detachment of the material from the container. These disadvantages can be prevented by designing the edges of the fluid-tight layers. In order to give the package a more optically attractive design or for the representation of the information, at least one of the layers can be provided with an impression. In both the process of a corresponding preform for the manufacture of the container and in the subsequent filling or use of the container by the consumer, it is an advantage that the printing is resistant to rubbing. That means that the impression will not be evicted by rubbing by direct contact or by an action in one of the layers. With a construction of a layer of the material of the wall of the container, this impression is placed on the outer side of the container. This correspondingly goes for the co-extruded layers. With an otherwise multi-layered construction, however, it is an advantage that the printing is provided on the inner side of the outer layer and / or the outer side of the exchange and / or an inner side of the exchange and / or one side of the inner layer. This makes it possible to combine several impressions, which may differ in their graphic design or design in terms of color. In order to be able to supply sufficient heat in a simple manner for the connection of the preform to itself, at least one of the layers can be ultrasonic absorber. The absorption of the ultrasound results in heating of the corresponding layer, which is at least sufficiently strong for the layer to soften sufficiently to form an intimate and particulate fluid-tight connection with a layer at the edge or surface contact therewith. , after a corresponding cooling. This can naturally be true for both layers in contact in the overlap region, particularly if they are made of the same material. However, in this relation, it should be noted that the heating of the corresponding material by ultrasound does not result in * the transparency of the material that will be negatively influenced after the connection and cooling.

If the layers are formed by a laminate, which can be considered is advantageous for printing, when printing before laminating the layers. This, on the one hand, prevents exposure to harmful influences directly on the outside of the container and, on the other, there is no risk of harmful effects to the food. In the construction of layers of the material, it is also possible that one of the layers is itself a laminate. There is also the possibility of only two or even more layers of the corresponding material being co-extruded. There are several possibilities of closing the container at its lower end. In one embodiment, the closed end can be formed by connecting lower end sections of the wall. Therefore, essentially also the closed end is formed by the wall of the container and its material and is transparent and in particular fluid-tight. In this case, preferably the lower end sections of the wall are pressed together before being connected, so that the wall section can also be connected to itself, by a corresponding thermal effect.

It is also possible to use a separate part to close the container, so, for example, the closed end comprises a bottom insert. This can be done from a separate preform. Normally, the background insert does not have to be transparent. However, it is possible to prepare this bottom insert of the same material as the container wall and also to use correspondingly heat and pressure to connect the bottom insert and the container wall. To close the container in the region of the removal opening, a lid can be hermetically sealed, in particular at the edge of the opening. The material used for the wall of the container and possibly also for the bottom insert, is transparent, however, it can also be colored. This means that the material is not clearly transparent, but red, yellow green or similar, and that its possibility is more of a color transparency. In order to avoid possible negative influence of the element by the printing, it can be printed only on the outer side of the package, in case of a material of a layer. This can also be analogously done in the case of a multiple layer, of a polyethylene-based material. Such material is possibly also prepared by co-extrusion. Naturally there is no negative influence on the food by the material of the container or by the penetration or loss of fluid due to the tightness of the container. In order also to prevent the container from being damaged more easily, even in the case of falling, in a filled or unfilled condition, this material may be impact resistant and / or puncture resistant. For the package, various configurations in cross section are possible, which may also vary in the longitudinal direction of the package. This change not only includes the dimensional changes of a cross section, otherwise identical, but also changes related to other configurations in cross section. Examples of such cross-sectional configurations are circular, approximately polygonal, approximately quadrangular and, in particular, square, oval, bean-shaped or the like. The printing can be done in a usual manner, by printing a corresponding resource, such as a color or the like. There is also the possibility of preparing the print not only by printing such a color, but also by printing on the corresponding layer or even by carving or the like. The print can also have a three-dimensional effect or be a hologram or at least understand the same, and this print can also have a brilliant effect. It is also possible that the print covers the entire package, except in the control window and the inside of the package can only be scanned through the control window. In this regard, it is also possible that several control windows are arranged in the longitudinal direction of the container and / or in the circumferential direction of the container. Therefore, several areas inside the container can be seen. For example, depending on the color of the print, there is also the possibility that the print itself becomes only visible after at least part of the food has been removed. This can, for example, be done because certain parts of the print will only be visible after a sufficient amount of the food has been removed and these parts have been replaced and thus result in a changing impression. Such an impression that appears or changes can, for example, serve to make possible certain residues or the like, where one can identify if there is a possibility of winning something, only after a sufficient quantity of food has been removed.

The edge of the opening can be turned round, as mentioned above. This rotated round can be a single or multiple laminate, at an angle of 90 ° or more relative to the rest of the wall. Thus, for example at a 90 ° angle, the edge of the opening projects essentially radially outwards from the removal opening. In order to be able to drink, for example, a liquid food from the package, at any location of the removal opening, the opening edge advantageously extends along the entire periphery of the removal opening. However, it is also possible that the opening edge is only partially continuous and / or in places. Of the above-described properties of the package and in particular of its material will not be provided, for example, only at room temperature, but also within a greater range of higher temperature, it is considered to be favorable that the package, and in particular its material , are stable in the temperature range from -50 ° C to + 120 ° C, for example, for the sterilization device. This stability, for example, refers to dimensional stability, transparency, fluid tightness and the like. In connection with printing, it should also be noted that there are also temperature sensitive impressions, which may also be used, according to the invention. Such an impression, for example, will change its color and thus the possibility of the content of the information, at a predetermined temperature. A consumer can thus identify, for example, whether a cooled food has a sufficiently low temperature, or whether a food is heated sufficiently. In order to be able to store a plurality of containers, in a simple manner and remove them from the container load, this container can be stacked and unstacked. With respect to the dimensional stability of the package, it should also be noted that this may be important in particular for the connection in the overlap region and the opening edge, for example to also continue the configuration of the package in the overlap region, which means imparting the corresponding configuration to a round or, for example, oval container, still in the overlap region. Also, the dimensional stability is to prevent leaks that could occur in these regions. With the food cooled or heated, the corresponding temperature must be maintained unchanged, if possible, at least for a certain period. To do this, at least one of the layers can be formed as a layer of heat insulation. Such a heat insulation layer can, on the one hand, be insulated to the heat due to the specific material, on the other, there is a possibility that the layer contains a heat insulation material, such as air or the like, or for it to be formed an air gap between two adjacent layers. As already mentioned at the beginning, the invention also relates to a preform for the manufacture of a container, described above, the preform serves for the manufacture of the container wall and possibly for the closed end and the opening edge. In the following, advantageous embodiments of the invention are illustrated in greater detail with reference to the figures appended in the drawing.

In the drawings; Figure 1 shows a side view of a first embodiment of a package, according to the invention; Figure 2 shows a section along line II-II of Figure 1; Figure 3 shows a section along the line III-III of Figure 1; Figure 4 shows a side view of a second embodiment of a package, according to the invention; And Figure 5 shows a plan view of a preform for the manufacture of a package, according to the invention, according to Figure 1. Figure 1 shows a package 1 in a side view, which has a dome design. The package 1 comprises a removal opening 7 at its upper end in Figure 1, which is surrounded by a laminated opening edge 8, also see Figure 2. A cover 21 is hermetically joined to the opening edge 8. At least in one place, a lid handle 22 serves to remove the lid 21 from the opening edge 8, which projects radially to the outside of the lid. Food 2, which can be liquid, pasty, throwable or emptied, is filled inside the container. This food 2 is filled in the container up to filling level 23. The container 1 comprises a wall 6 of the container, which is formed by a preform, according to Figure 5. The wall 6 of the container is made of a transparent and fluid-tight material. In the embodiment, according to Figure 1, the package 1 comprises a bottom insert 25 at its end 9 opposite the removal opening 7. It is placed, at least partially, on or in the wall 6 from the outside and connected therein in a fluid-tight manner. The insert 25 of the bottom can be made of the same material as the wall 6 of the container. This package 1 comprises an impression 15 in the region of the wall 6 of the package. The corresponding printing can, in particular with a material of a layer for the wall of the container, be provided on an external side 26 of the container 1 or on the outer side of the wall 6 of the container. With the construction of two or multiple layers, see in particular Figure 3, the impression is placed on the inner side 16 of an outer layer 3 and / or on the outer side 17 of a central layer 4 and / or on the inner side 18 of the central layer 4 and / or on the outer side 19 of the inner layer 5. Depending on the material of the layer used, the different arrangements of the printing on one of the sides of one of the layers, results in another optical appearance , the impressions can also be combined in different layers or sides of the layers, respectively, due to the transparency of the container wall 6. Such a combination can result in an optical effect, such as an apparent three-dimensionality of the print. Likewise, the combination of several impressions makes possible combinations of color of impressions of several colors, when a consumer watches the combined impression from the outside. In Figure 2, a section, along line II-II, of Figure 1 is represented. In this figure, one can see, in particular, how the wall 6 of the container bends or rotates round the outside at its upper end, to form the opening edge 8. The selection of the corresponding layer materials from the container wall results in the ductility when the opening edge is formed, as well as the dimensional stability after the configuration. In Figure 3, a section, along the line III-III, through the wall 6 of the package or the preform 10, according to Figure 5, is shown. In the embodiment shown, the container wall is obtained from three-layer materials. If only one layer of a material is used, it may be, for example, made of polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyamide (PA), polyethylene terephthalate (PET) or the like. . Such a single layer material is possibly provided with one or two lacquer coatings on its opposite sides to achieve a better seal with respect to the fluids. In the case of two or more layers, see reference numbers 3, 4 and 5 in Figure 3, for example, the inner layer can be made of PP, PVC, PS, PA, PET or similar, while the outer layer can be made, for example PP , Oriented PP, polyethylene (PE), PET, PA, oriented PA, or similar. In particular, the oriented PP, PET and OPA can also be lacquered. It is also possible that the oriented PP can be coextruded. The different 3, 4 and 5, according to Figure 3, can be joined as individual layers to form the wall 6 of the container. It is also possible for the layers to form a laminate, for at least one of the layers to be a laminate, or for the layers to be coextruded. It has already been pointed out that in the case of a material of a layer for the wall 6 of the container, the corresponding impression 15 is printed on the external side 26 of the container 1, while in the construction of multiple layers, the sides, internal and external , corresponding of the various layers, each one uses, without an impression being applied to the outer side of the outer layer and an inner side of the inner layer. In Figure 4, a second embodiment for a package 1 is shown, according to the invention. In this container, and possibly also in the container 1, according to Figure 1, the wall 6 of the container is flexible, so that the pressure can be exerted on the container 1 from the outside, in order to move the food towards the opening 8 of removal, to remove it or consume it. It is necessary, in particular in the case of frozen products, such as ice cream, in addition to the pressure, the heat of the consumer's hand is transmitted, so that a layer of liquefied food 2 is formed, at least between the same and the inner side of the container wall 6. The above materials for the different layers 3, 4, 5, according to Figure 3, provide a flexibility of the container wall 6. At the same time, in particular by the use of PET (polyester), a layer material is used, which stabilizes the corresponding configuration of the package 1, according to Figure 1 or Figure 4. Such layer material is flexible, but it is also relatively rigid.

The package 1, according to Figure 1, may comprise a handle 24 at its closed end), which is also formed by a preform 10 for the wall 7 of the package. To form this handle 24, the lower end sections 20 of the preform 10, see Figure 5, are pressed together, after the preform has been rolled into the corresponding container configuration and applying heat, they are intimately connected in a hermetic way to the fluid. Even without the formation of such a handle, the closed end can be formed by connecting these lower end sections 20. For simplicity, in package 1, according to Figure 1, a corresponding print 15, according to Figure 1, is not shown. In the preform 10, according to Figure 5, it should be noted that it comprises a surrounding edge 14. It may be sealed to prevent fluid penetration. After the preform 10 has been rolled, the rolling condition can be fixed, for example, by arranging longitudinal edges 14 which face in abutment relationship and are joined directly or by means of an additional connecting element. It is also possible that the edges 14 overlap to form an overlap region 12, which extends essentially in the longitudinal direction 11 of the package and so that the preform is directly bonded to itself by means of a connection of the outer layer 3 and the inner layer 5. Additionally, an adhesive may possibly be disposed in overlap region 12. To form the corresponding handle 24, according to Figure 4, the sections 20 of the lower end of the preform 10 can be pressed together and joined together. This connection can be made simultaneously with the connection in the overlap region 12. An upper end section of the preform 10, designated "8", serves as the opening edge 8, after it has been bent or turned to the outside, see Figures 1 and 2. The embodiments shown, according to the Figures 1 and 4, are only exemplary and other container configurations are possible, such as containers with the inverted cone design, compared to Figure 4, stretched, long tubular containers, or the like. It is also possible for the corresponding fluid-tight and transparent material that the container wall 6 is only arranged in a circumferential section of the container wall in the longitudinal direction of the container 11, while the other sections of the container wall 6 of several spaced subsections corresponding to the transparent section, can also be composed of several subsections spaced in the longitudinal direction 11 of the container, which are possibly out of line in the circumferential direction of the container 1. For a simplified manufacture of a corresponding container 1, however , it is normally advantageous for the entire wall 6 of the container to be made of a corresponding transparent material that is fluid-tight and possibly multi-layered. This in particular facilitates the arrangement of the impression 15 inside the material of the wall 6 of the container. In the following, the advantages, according to the invention, are again briefly summarized with respect to the important advantages for the consumer and for the process. One of the important advantages for the consumer, according to the invention, is that the corresponding container is characterized by the same visual peculiarities. For example, the package can be prepared in various configurations, such as oval, circular, approximately square or even polygonal, as well as in the form of beans and the like. Due to the transparency, in particular in the region the visible spectrum, the contents of the container are likewise visible without having to open this container. Both the level of filling and the condition of the food can be checked in a simple way. Various printing possibilities result in further visual benefits. The print can also have a design that has a bright effect, which particularly emphasizes the impression optically. Also, printing can have a three-dimensional effect. It is possible to supply the complete package with one print, except in at least one window. The impression can be formed by a hologram, which offers further optical advantages. Also, the print may become visible, at least partially, after the food has been taken out, which makes it possible, for example, to inform the consumer about a prize he won, or the like. The consumer has a number of further functional advantages, with the package, according to the invention. One of these advantages is the tightness of the container with respect to gaseous and / or liquid fluids. The tightness refers to both the penetration and the escape of a corresponding fluid. One can also do it without the tightness of the corresponding fluid, if the container is filled with a particular dry food, of which the properties corresponding to the consumption are not negatively influenced, for example, by the exchange of a gaseous fluid through the wall. of the container. That means that the food is not attacked, for example, by oxygen, carbon dioxide or similar, and that it is still suitable to be consumed without restrictions. Further advantages of the container, according to the invention, are its flexibility, due to which the corresponding food can be pressed out of the container. Simultaneously, the container, however, is sufficiently resistant to external actions, such as impact resistance and shock-proof. This means that if the container falls, it will not be damaged and even sharp objects can not easily pass through it. At the same time, the package is elastic, it takes its original configuration even after it has been compressed. The tightness of the container is also advantageous since the fluid can not penetrate or escape. The resistance of the container also applies to the connection of the individual layers, so even a single partial detachment of a layer is impeded. Therefore, the package is excellent for storing food, without its properties being negatively influenced by external actions or packaging materials with respect to the consumption of the food. The dimensional stability of the package is selected so that it is flexible and automatically takes its original configuration and also maintains its predetermined configuration and its other properties, particularly in the deformed areas of the package, such as the edge or the conglutinated layers. Printing, likewise, is designed and arranged so as not to have a negative influence on the properties of the food or not to be easily removed from the package in some way, by rubbing, displacement or the like. At the same time, the container is made of a material that offers a pleasant touch to the hand, even with chilled or heated food. Apart from the plurality of advantages for the consumer, there are a similar number of advantages relative to the process. The ease of sealing the package, according to the invention, during its manufacture, is an advantage that is particularly important for the conglutinated portions of the preform. However, the packaging is not only airtight in these conglutinated areas, but also due to the packaging materials. Also, this package is suitable to be printed or provided with an impression in a simple manner, a number of possibilities for joining the printing onto one or more of the layers of the material being available. Due to the uniform surface of the preform, it can be easily processed and transported. Despite the flexibility of the packaging material, it can be configured and maintain its configuration in the configured areas, as desired, such as, for example, in the edge region of the removal opening. This dimensional stability is also useful for the joint or the conglutinated areas of the container, which also maintain their corresponding configuration in the cross section of the container. This results in an ease of further processing or filling the container, since it retains its originally intended configuration, due to its dimensional stability and as, for example, a circular configuration originally attempted does not change in an oval or even flatter configuration , in the course of time. This dimensional stability and the corresponding configuration of the package also results in a good stacking and unstacking capability, which is also advantageous in terms of production and transportation.

The hermetic shape of the container is important to fill the corresponding food, both during filling and in the subsequent transport, since there is no risk of a penetration or leakage of a corresponding fluid. It is equally advantageous that the package is resistant, both with respect to the lower and higher temperatures, and with respect to its properties and its configuration. This means that, for example, a food can be filled in and subsequently cooled without changing its properties, such as airtightness, flexibility, dimensional stability, transparency or the like. This is analogously true for high temperatures, which are, for example, advantageous for sterilizing the package. Likewise, correspondingly high temperatures can also occur if the package is used to consume a heated food. Finally, another advantage relative to the process is that the container can be easily sealed in a sealed manner, by a cover, which can be placed particularly in the removal opening and hermetically connected to the corresponding opening edge.
