DESCRIPTION

Drink container with improved perforation possibility

The invention relates to a beverage container, in particular a beverage bag with a pierceable opening that is pierced with a straw. Such beverage containers, in particular beverage bags, for example, with a bottom that is still standing, are known to the state of the art. They can be produced, for example, from metal sheets, from a monomaterial or from multilayer composite materials.

With such beverage containers, in particular, with the beverage bags, problems may arise when the straw is pierced. In particular, the liquid may spill out in the case of a flexible beverage bag as a result of the pressure during the piercing with the straw. In addition, if excessive pressure is applied, not only the pierceable hole can be pierced but also the other side of the beverage container.

At the same time it must be ensured that such a beverage container does not harm the environment, that in particular metal sheets that can be thrown into the environment are not used.

For example, such beverage containers with a perforable opening are known from EP 0 600 502 A2, US 2006/0056744 or US 5,873,656.

The present invention has as its main objective to present a beverage container with an improved perforation possibility.

This objective is achieved with a beverage container according to claim 1. Advantageous embodiments are described in the dependent claims.

A beverage container, in particular, a beverage bag according to the invention, such as a metal foil bag that is kept standing, comprises a pierceable opening that is pierced with a straw. This perforable opening is perforated in the beverage container at the place where usually the total wall thickness of the beverage container is perforated through, this means in particular, for example, the full thickness of the metal sheet of a beverage bag . On the inner side of the beverage container, a sealing sheet exposed to the outside is fixed around the pierceable opening by means of a weld. Particularly set forth herein means that no other sealing foil, sealant paper or the like is attached from the outside.

By means of this weld comprising an internal welding edge (on the side of the weld facing the perforable opening) and an external welding edge a hermetic seal is formed, such that the beverage container can be filled with a Drink without leaks.

According to the invention, a pocket is now formed in such a beverage container between the inner weld edge and the bottom edge of the pierceable opening, in which pocket the material of the beverage container and the sealing sheet are not connected one with the other.

It is noted that a pierceable opening comprises an upper edge and a lower edge that are connected to each other in the transition areas between the upper and lower edges, for example, circularly or with edges. The lower edge may comprise, for example, a straight section or be configured as such.

The pocket designed according to the invention can facilitate the introduction of a straw and the perforation of the beverage container. It can, in particular, help guide the straw in the direction of correct perforation so that penetration through the opposite side of the beverage container is less likely.

This can facilitate, for example, that a straw while it is inserted in the pocket can be previously oriented (this means that it is symmetrically arranged with respect to the pierceable opening) and / or is stabilized by means of the pocket and / or the edge bottom of the perforable opening, so that a controlled perforation of the sealing sheet is possible.

Usually, the sealing sheet that is exposed to the outside is made of a material that can be more easily perforated than the material of the beverage container. In particular, the exposed sealing sheet may be designed to be thinner and / or manufactured from different materials than the beverage container. However, it can also be manufactured from the same materials that can be arranged with the same combination or with a different one and can have the same or different thicknesses as the materials used in beverage containers. In particular, such a sealing sheet and / or the metal sheet of a beverage container can be designed with several layers, where at least one layer can comprise an oxygen barrier. However, the sealing sheet and / or the beverage container can also be formed from a monomaterial.

The pierceable opening is usually arranged in the upper region of the beverage container. In particular, it may be arranged in the upper third, in particular in the upper room, in particular in the upper fifth of the beverage container. It may be arranged on a horizontal surface or preferably on a side face of the beverage container. In metal foil bags, the pierceable opening is usually perforated on a side face.

Hereby, a beverage container is referred to as being in an upright position when it is arranged such that the pierceable opening is disposed in the upper region (in particular, in the upper half) of the beverage container (herein , the upper region is also designated as "upper part") and if an optional lower part is provided, for example, a lower part that remains standing, the latter is arranged horizontally, this means that the bag is for example in position vertical. All indications that require an orientation of the beverage container, for example, "upper" and "lower", "upper edge", "lower edge", "horizontal" and "vertical" and more spatial indications on symmetries and the like refer to a beverage container in an upright position, if not indicated otherwise.

Next, some embodiments of the invention will be described without explicitly describing the respective possible variations as a result of the possible inaccuracies of finishing. However, a deviation from the described properties that is less than the precision of finishing is also implicitly included in the description. In particular, beverage containers whose deviations from the described properties are within the precision of finishing are also included in the claims and the description. In particular, the finishing precision may be less than 1 mm, in particular less than 0.5 mm and in particular, for example, less than 0.2 mm. Finishing inaccuracies can result, in particular, in the relationship between the positions of the pierceable opening and the weld, since these can be done with different machine parts. The shape of the pierceable opening itself and the shape of the weld itself, however, only have very small finishing inaccuracies that are less than 0.1 mm or 0.2 mm, because they are produced with dies of fixed tool. In particular, in the conformation of the pocket, it is preferred that the imprecision of finishing at the top and bottom of the pocket be less than 0.5 mm, particularly less than 0.2 mm is preferred.

According to an embodiment of the invention, the distance between the inner weld edge and the bottom edge of the pierceable opening is longer than the distance between the inner weld edge and the top edge of the pierceable opening.

The distances can be determined herein, for example, as follows: with a beverage container in an upright position, the distance between each point of the bottom edge of the pierceable opening and the closest point of the inner weld edge is determined. The maximum value of the distances determined in this way is then the distance between the lower edge and the internal welding edge. The distance between the points of the upper edge of the pierceable opening and the respective closest point of the inner weld edge is determined analogously. The maximum value of these distances is then the distance between the upper edge and the inner welding edge.

In particular, the distance between the inner weld edge and the bottom edge of the pierceable opening may be longer by more than 20%, in particular more than 50%, in particular more than 100%, in particular more than 200%, in particular more than 300% than the distance between the inner welding edge and the upper edge of the pierceable opening.

The inner weld edge can also form, for example, a notch, for example, a funnel or triangular or rectangular type cavity towards the weld that may be included in the pocket. Thus, for example, the direction of perforation of a straw can be predetermined. In addition, welding with the internal welding edge and the external welding edge may have an additional notch in the region below the perforable opening and in the region of the pocket, where the pocket obtains an additional notch downward which can orient the tip of the straw in the horizontal direction, for example center it horizontally with respect to the pierceable opening.

In some embodiments of the invention, the bottom edge of the pierceable opening may be designed to be flatter than a circle that encloses the pierceable opening or may comprise a region that is flatter, that is, less curved than a circle. which encloses the pierceable opening.

In particular, a circle that encloses the perforable opening may be the smallest circle that completely encloses the perforable opening. The latter can be clearly determined for each shape of the pierceable opening. According to the embodiment described above, the curve of this enclosure circle is larger than the curve of the lower edge or a part of the lower edge. A lower edge may comprise, for example, an arc of a circle with a constant curve that has a smaller curve than the smaller circle that encloses the perforable opening. This is true automatically, for example, with a lower edge configured as a straight section or a lower edge comprising a straight section.

In some embodiments of the invention, the pierceable opening may be symmetrical with respect to a vertical plane.

As an alternative or in addition, the internal and / or external welding edge can be configured to be symmetrical with respect to the same vertical plane or a different one. At this point, it should be noted once again that this also includes beverage containers that only have this characteristic within the precision of finishing.

In particular, with a perforable opening that is symmetrical to a vertical plane and / or an internal weld edge that is symmetrical to a vertical plane, the pocket may have the region of greatest expansion in this plane of symmetry or in one of these Simetna planes. Thus, in particular, the connection between a point on the lower edge of the pierceable opening and the closest point on the inner weld edge is the point of all points of the lower edge that reaches the maximum for this distance which is achieved in this combination of perforable opening and internal welding edge that can be in this plane of symmetry or in one of these planes of symmetry.

In some embodiments of the invention, the pierceable opening can be designed such that it is not symmetrical with respect to each horizontal plane. A horizontal plane is defined herein as a plane that extends horizontally when the beverage container is held vertically.

This feature may in particular mean that the pierceable opening is not precisely circular but only has, for example, a certain symmetry in the vertical direction.

In some embodiments, the bottom edge of the pierceable opening is configured to be flat. This may mean, in particular, that the lower edge comprises a region with a curve that is smaller than the curve of a region (or all regions) of the upper edge or of the remaining parts of the pierceable opening.

In some embodiments of the invention, the pierceable opening is configured to be wider at the bottom than at the top. This may mean, in particular, that the widest region is obtained at the bottom at the bottom edge that is configured, for example, as a straight section. In other embodiments, this may mean that the widest region is obtained in the lower half, in the lower third, in the lower fifth or in the lower tenth of the perforable opening.

Each lower fraction / upper fraction can be considered in the present description as the fraction of the pierceable opening / of the container which is determined as follows: between the lowest point or one of the lowest points on the lower edge and the point higher or one of the highest points on the upper edge, a straight section is placed. Then the fraction of the section corresponding to the desired fraction of the pierceable opening / of the container is determined. For the lower fraction / upper fraction, this fraction is then marked (mentally) from the bottom / from the top along the section. A horizontal (mental) plane through the container in a vertical position through this point will divide the pierceable opening / beverage container and determine the lower / upper fraction of the beverage container, respectively.

In some embodiments of the invention, the edge of the pierceable opening is partially or completely curved and / or non-circular. In particular, the edge of such a pierceable opening may comprise, for example, an arc of a circle or two arcs of a circle or more than two arcs of a circle.

In some embodiments, the edge of the pierceable opening is partially or completely defined by straight sections, so that the pierceable opening may be partially or completely defined by straight sections. In particular, the edge of the pierceable opening can be configured as a polygon, for example, as a triangle, in particular, as an isosceles triangle, in particular, for example, a rectangular or equilateral triangle (equiangular).

The parts comprised by the edge of the pierceable opening, for example, the upper and lower edges or portions comprised therein, can each be connected in an angular or circular manner. A polygon can have, for example, rounded edges (which means that the straight sections are connected in a circular way).

For example, the pierceable opening may have a crescent shape, where the straight section is usually horizontal and the curved portion is arranged above the straight section when the container is held in an upright position. The curved part and the straight section of the edge of the pierceable opening can be connected to each other in an angular or circular (round) manner. The curved part can be, for example, configured in the form of an arc of a circle or comprise arcs of an oval, in particular, be configured to be semicircular or semioval.

In beverage containers according to the invention, the internal and / or external welding edge can follow the shape of the pierceable opening (for example, the upper edge) on the upper side of the perforable opening. On the lower side, the internal and / or external welding edge may have a different shape than the lower edge of the pierceable opening (for example, the lower edge). In this way, for example, the pocket can be shaped.

In beverage containers according to the invention, the internal and / or external welding edge can be configured to be curved and / or non-circular. In particular, the internal and / or external welding edge can be, for example, oval or comprise one or two or more arcs of a circle with different curves that are circularly connected, this means that the transition is not usually and in particular configured to be angular. In some embodiments, all or only some of the arcs of a circle may, however, be angularly connected.

In some embodiments, the internal and / or external welding edge of the beverage containers according to the invention can be configured to be flat at the bottom. For example, it may comprise a region in the lower region (the lower part), where the curve is smaller than in another region of the respective welding edge (this means a smaller curve in the inner welding edge in a lower region than in another region of the inner weld edge and / or a smaller curve in a lower region in the outer weld edge than in another region of the outer weld edge), for example, in the upper region and / or in the lateral regions . In addition, for example, the region of the internal and / or external welding edge located below the lower edge may be less curved than the region of the respective welding edge located above the upper edge and / or one or all of the lateral regions of the respective welding edge.

For example, the curve of the internal and / or external welding edge may be smaller on the lower side, this means, for example, in the lower half, in the lower third, in the lower fifth or in particular in the lower tenth of the respective welding edge that a curve or that all the curves in the regions of the upper part of the respective welding edge and / or that the smallest circle curve in which the respective welding edge may be inscribed. The circle may in particular be the smallest circle in which the respective welding edge may be inscribed.

A beverage container according to the invention can comprise a straw with which, for example, it can be distributed. This may mean, in particular, that a beverage container is usually sold with a straw. Such a straw may be fixed, for example, in the beverage container. As an alternative, a quantity of drinking straws (for example, a corresponding one or a longer one) that is suitable for these beverage containers can be included in a package with several such beverage containers or there may be a possibility that Drinking straws are distributed manually whereby the beverage container can be opened together with the beverage container. The straw can be wrapped (individually) or not wrapped. On the other hand, several drinking straws can be wrapped in a wrapper. For example, one (or several) wrappers with an amount of drinking straws can be included in a wrapper with several beverage containers. In particular, the total amount of straws that are included in one or more wrappers in a package with several beverage containers is usually equal to or greater than the quantity of beverage containers in the package.

Usually, in beverage containers according to the invention, the diameter of the straw is smaller than the diameter of the perforable opening at its smallest point. This means that such a straw can usually pass through the pierceable opening without it being necessary to compress the straw, for example, to press it. On the other hand, the diameter of the straw can also be the same or (somewhat, for example, up to 15%, in particular up to 10%, for example, in particular up to 5%) greater than the diameter of the perforable opening in the point of its smallest diameter. This can be advantageous, for example, since it can reduce the likelihood of liquid leakage after the penetration operation.

In this case, the diameter of the straw is considered to be the diameter of the smallest circle in which the straw can be inscribed when the straw is observed perpendicular to the axis in the direction in which the beverage can be sucked through the straw . With a straw having an oval cross section that is perpendicular to the axis in the direction through which the beverage can be suctioned with the straw, the diameter could be, for example, the longitudinal axis of the oval symmetry.

Such a straw may optionally comprise a pointed end on one side so as to allow easier introduction or perforation in the beverage container.

In particular, a sealing sheet according to the invention, e.g. For example, with a straw with a pointed end, it can be perforated more easily to open it because the pocket and in some embodiments also the lower edge of the pierceable opening comprising, for example, a flat region could ensure the previous orientation, so that the tip meets symmetrically with the sealing sheet and can more easily penetrate the latter.

In some beverage containers, the maximum extension of the pocket to the bottom can be at least 1 mm, in particular at least 2 mm and in particular, for example, at least 3 mm. Alternatively or in addition, the maximum extension of the pocket to the bottom may be greater than one fifth of the diameter of the straw, in particular it may be greater than one third, in particular greater than half of the diameter of the straw. The straw can comprise a pointed end.

In order for the weld to enclose the pierceable opening, the inner and / or external weld edge includes a curve, this curve preferably only runs in one direction (inward toward the center of the pierceable opening). Preferably no regions are provided where the inner and / or outer welding edge bends outward (in the opposite direction of the pierceable opening) or is only provided in no more than two regions. Such regions with an outward curve may be provided, for example, to obtain, below the perforable opening in the pocket region, an additional notch of the pocket that is preferably centered below the center of the perforable opening.

In some embodiments of the invention, the pierceable opening is not circular. For example, the edge of the pierceable opening may comprise at least two regions with different curves, for example an upper edge comprising at least one region in a region and a lower edge comprising at least one region in a region where preferably the curve in the region considered for the lower edge is smaller than the curve in the region considered of the upper edge. In particular, the curve may be smaller for each point of the lower edge than for each region of the upper edge, this means that the maximum curve in any region of the lower edge may be less than the minimum curve in a region of the upper edge. In this way, the straw straw can already be provided by the pierceable opening.

In some embodiments, the edge of the pierceable opening may comprise one, two or more curved regions and one, two or more straight regions that can also serve as a straw for a straw.

The upper and lower edges can be found respectively in the transition regions that can be configured to be, for example, circular and / or angular. In addition, parts of the upper and / or lower edge can be found in the transition regions that can also be configured to be angular and / or circular. These transition regions can be neglected for the determination of the curve of the upper and / or lower edge.

In some embodiments, the width of the pierceable opening is greater than the height of the pierceable opening. In this case, the maximum distance between two points at the edge of the perforable opening in the horizontal direction is considered as the width of the perforable opening and the maximum distance between two points at the edge of the perforable opening in the vertical direction is considered As the height. This can be advantageous, for example, because there is enough space to drill and guide the straw. This in particular leads to the fact that a straw can be inserted better into the perforable opening from above than laterally.

In some embodiments of the invention, the relationship between the width of the outer weld edge and the height of the outer weld edge is greater than the relationship between the width of the inner weld edge and the height of the inner weld edge. Again, the maximum distance between two points at the inner / outer weld edge in the horizontal direction is considered as the width of the inner / outer weld edge. The maximum distance between two points on the inner / outer weld edge in the vertical direction is considered as the height of the inner / outer weld edge. This can be advantageous since this can lead to an increase in welding stability in the lateral region of the pierceable opening.

In some embodiments, the external welding edge and / or the internal welding edge is configured not to be circular, but comprises at least two regions with different curves. In this way, the shape of the weld edge can be adapted to the shape of the pierceable opening. In this way, the introduction of oxygen through the pierceable opening in the filling can be minimized.

In some embodiments, the maximum pocket extension may be located in a symmetry plane of the pierceable opening and / or of the internal and / or external welding edge and / or of the beverage container. In some embodiments, this maximum extension is only obtained in the symmetry plane. This can be advantageous since in this way a straw can be guided along the simetna plane.

In other embodiments, the maximum pocket extension is not only obtained in a symmetry plane. Normally, the maximum distance between the upper edge of the pierceable opening and the inner weld edge is less than the maximum pocket extension. This can also help guide the straw.

Additional embodiments and examples are shown in the following figures. In the figures:

(with an internal welding edge) as described in Figure 2 and its corresponding description.

At the edges, such a drinking bag may comprise, for example, sealing seams 4. If such a bag is a standing bag, it usually comprises a lower part that remains standing (not shown here) . A straw 5 can be fixed in such a drinking bag. In this case, this straw 5 is shown fixed, for example, stuck in the bag. However, it can also be connected to the bag in any different way or distributed along with the bag. Such a straw can be wrapped in an additional wrapper, for example, a transparent or non-transparent plastic cover, where the additional wrapper can be fixed (for example, glued) to the beverage bag (not shown here). Usually, such straws have a pointed end 5a that can also help pierce the beverage container. Now, to drink the beverage from the beverage container you can remove the straw, unwrap the straw if it is wrapped and then pierce the pierceable opening 2 through the sealing sheet. Then the drink can be removed through the straw.

Figures 2a to 2c show possible embodiments of the pierceable openings 2 that are present in the beverage container with the respective internal sealing weld edges 3. The pockets 6 that are formed between the bottom edge of the pierceable opening and the Internal welding edges are also drawn in each figure.

In particular, Figure 2a shows a pierceable opening 2 having a crescent shape. This can be, for example, a segment of a circle. In this example, the upper edge 2a comprises an arc of a circle and the lower edge 2b a straight section or are configured as such. Preferably, such pierceable opening 2 is arranged in a beverage container according to the invention such that the straight edge is located at the bottom. In this way, pocket 6 can also extend down. The connection between the arc of a circle and the straight section can be configured to be angular or circular (not shown here).

If now a straw, which usually has a diameter that can be placed in the pierceable opening, is inserted into the pierceable opening, it can be previously oriented by the bottom edge 2b, for example a straight section as shown herein. in such a way that the tip meets the sealing sheet and can pierce the latter.

At the same time, the pocket 6 towards which the straw is milled can reduce the probability of also piercing the back of the beverage container by perforating the straw perpendicular to the surface of the container.

In addition, the straw can also be guided through the upper edge 2a of the opening 2 since this region usually turns the straw in the direction of the symmetry axis (if present as in this example) of the pierceable opening 2.

The internal welding edge 3 of Figure 2a can be described in the example shown, for example, as comprising two arcs of a circle that are circularly connected.

In particular, the inner weld edge may follow at the upper edge of the perforable opening approximately the shape of the upper edge of the perforable opening, so that the distance remains approximately equal between the limit of the perforable opening which is in the form of a arc of a circle and the inner welding edge.

At the lower edge of the pierceable opening, the internal weld edge 3 may, as in this example, have a different edge shape than that of the lower edge 2b which is hereby designed as a straight section. In the example shown here, it is curved. However, as shown by way of example, the curve of the inner weld edge may be less different in the lower region in the example shown than in the upper region and / or in the lateral regions of the inner weld edge. .

Usually, the inner and / or outer weld edges do not have edges as they are stamped, eg, particularly in tension. In particular, the parts of the internal and / or external welding edges with different curves are therefore usually circularly connected.

A perforable triangular opening 2 is shown in Figure 2b. Here, a side of the triangle which in this example is approximately equiangular is located at the bottom. The inner weld edge 3 in the example is shown configured in such a way that the pocket 6 that is at the bottom is larger than the pockets formed near the upper sides of the triangle. In particular, an inner weld edge 3 can be formed around an equiangular triangle in a circular shape, as shown, where the circle is displaced downward such that a pocket 6 is formed at the bottom. Preferably, the distance between the lower edge 2b and the internal welding edge 3 is greater than the distance between the upper edge 2a and the internal welding edge 3. Thus, a pocket 6 is shaped as described. In particular, the distance between the lower edge 2b and the internal welding edge 3 may be greater by at least 10%, in particular at least 20% and in particular at least 50%, in particular at least 100% than the distance between the upper edge 2a and the internal welding edge 3.

In other embodiments, the internal (and / or external) welding edge can also be configured by means of several arcs of a circle that are circularly connected. In particular, the lower region (lower part) of the inner (and / or external) welding edge may be designed to be more flat (this means less curved) than one or more or all arcs of a circle or regions of the respective edge of remaining solder.

A pierceable opening can also be configured as an isosceles triangle or other triangle (not shown here). In some cases, triangles can also have rounded edges.

In Figure 2c another pierceable opening 2 is shown with another internal welding edge 3. In particular, the pierceable opening 2 in this case is defined by two arcs of a circle 2a, 2b. The arc of a circle that defines the lower region (in this example it is comprised of the lower edge 2b or the lower edge 2b) is in the example shown flatter than the upper arc of a circle (which in this example is comprised by the upper edge 2a or is configured as the upper edge 2a) which means that it has a less different curve. In the example shown in Figure 2c, the arcs of a circle are found in such a way that they form edges. In other embodiments (not shown herein), the regions in which the arcs of a circle of the edge of the pierceable opening 2 join can also be rounded as already described above, for example, for the edge Internal welding 3.

The inner weld edge 3 shown in Figure 2c can also be described as being defined by two circle arcs with different curves. In particular, again here, the curve of the lower region is flatter than the curve of the upper region (and / or of the side region or regions). In the example shown, the two arcs of a circle are connected in a circular way, so that there are no edges that conform as it could increase the tension in the inner welding edge 3. Also with an external welding edge, the arcs of a circle that are comprised by the welding edge can be circularly connected so that no edges are formed.

In other embodiments, the internal (and / or external) welding edge 3 can also be designed to be circular or as an oval.

Each of the inner and / or outer weld edge may be symmetrical with respect to one or two or more planes (eg, vertical and / or horizontal).

In the example shown in Figure 2c, the bottom edge of the pierceable opening is (slightly) convexly curved or comprises a (slightly) convexly curved region. In other examples, it can also comprise curved regions (slightly) concavely or be curved (slightly) concavely.

In Figures 3a and 3b, two alternative possibilities of fixing the sealing sheet inside the bag are shown. The perforable opening 2 is drawn in the two examples shown, but it can also be invisible from this direction in some embodiments (for example, if the sealing sheet 9 is opaque).

Figure 3a shows an embodiment where the sealing sheet 9 is attached to the pocket as a strip. Here, usually the two ends of the sealing strip are fixed on the edge seals (sealing seam) 4 of the metal foil bag, so that less force is applied to the weld 7 and in particular the welding edge internal 3 and the external welding edge 8 in the finished beverage container since it does not have to hold the sealing sheet 9 without additional support.

Usually, the weld 7 with the inner weld edge 3 and the outer weld edge 8 and the pierceable opening 2 are then held in the center of the sealing sheet. However, the pierceable opening 2 and / or the weld 7 with the inner weld edge 3 and the outer weld edge 8 may also be subject to other points than in the center of the sealing sheet 9. A sealing sheet may, but You don't have to understand simetna axes. A pocket 6 is formed between the bottom edge of the pierceable opening 2 and the inner weld edge.

In the embodiment shown in Figure 3a, the inner and outer weld edges 3 and 8 are configured such that in the lateral regions, the width of the weld 7 is greater than in the upper and lower regions of the welder. This can be advantageous, for example, in terms of manufacturing, when transporting the material of the beverage container (for example, the metal foil for the bags) and the sealing foil 9 during welding of the material of the packaging Drink with the sealing sheet (where lateral indicates the direction that is lateral in the finished pocket), so that a larger force will act on the side of the weld than in the upper and lower regions. This can be advantageous, in particular, since the sealing (support) seams 4 are possibly not present at that time. Some force may be produced on the side regions of the weld 7, for example, when the sealing sheet and / or the material of the beverage container, eg, of a coil or should be unrolled by traction, e.g. .ej., during operation.

In other embodiments, the internal welding edge 3 and the external welding edge 8 may also have a constant distance from each other or may comprise the maximum distance from each other in other regions than on the sides.

In the example shown in Figure 3a, the pierceable opening 2 has a half-moon shape with an internal weld edge 3 that can be described as two different arcs of a circle that are circularly connected. However, the pierceable opening 2 and the internal welding edge 3 may also comprise any of the other embodiments described above.

Figure 3b shows an embodiment in which the sealing sheet 9 is supported by welding 7. The inner and outer welding edges 3 and 8 are also drawn. Here, the distance between the two welding edges 3, 8 may be constant or vary. For example, the distance between the two welding edges 3, 8 may be greater in the lateral regions than in the upper and lower regions of the weld, as described, for example, in Figure 3a. Other embodiments, where the internal and external welding edges 3, 8 have their maximum distance at other points than in the lateral regions, are also possible.

In addition, the outer welding edge may extend partially or completely to the edge of the sealing sheet 9. The sealing sheet 9 may comprise one or more symmetries or have no symmetry.

In an embodiment in which the sealing sheet is fixed in the beverage container, in particular, the beverage bag, as a patch where the patch can be, for example, rectangular, square, oval or round or have some other shape. For example, two sides of the patch may be parallel with respect to each other, while the other limits of the patch may have an arbitrary shape, in particular, for example, they may also be torn off or frayed irregularly.

Such a patch may in some embodiments hang beyond the outer weld edge in all regions of the outer weld edge. In other embodiments, the patch may hang beyond the outer weld edge in some regions of the latter and in others end with the outer weld edge. In other embodiments, the outer weld edge can respectively extend completely to the edge of the patch.

An embodiment in which the sealing sheet 9 is supported by welding 7 can be advantageous since less material is required for the respective sealing sheets. Here, the sealing sheet is fixed to the metal sheet as a patch, where the patch is held by welding 7. In this case, a perforable opening 2 and the pocket 6 can also be seen again. The perforable opening 2 in this Case is shown as having a crescent shape. In the same way as in Figure 3a, all other perforable openings and weld edge shapes, as described or shown above, can be used for internal and / or external weld edge 3, 8 in such an embodiment.

In both embodiments described in Figure 3a and Figure 3b, the sealing sheet that is located on the side of the inner weld edge, where a perforable opening is not provided, can be welded flat to the bag.
