FIELD OF THE INVENTION

The present invention relates to a container for use in a beverage preparation machine and a process for obtaining a front part of such a container.

TECHNICAL BACKGROUND

A container for use in a beverage preparation machine may be a capsule or a pod, e.g. a round coffee pod. The container or a part of the container is typically manufactured by separating a blank. The separating process may be a cutting process such as punching, and the blank may be a sheet, for example from a roll of sheets or material. The separated blank is then subsequently formed and sealed with another separated blank, for example separated from the same blank, thereby making the container or at least a part of the container. The container may contain an ingredient such as coffee or tea. The ingredient may be dosed before sealing so that the ingredient is contained in a compartment of the container.

The container needs to be handled by a user for being appropriately used in the beverage preparation machine. In particular, the container requires a defined position and orientation with respect to the beverage preparation machine so that the ingredients contained in the container can be appropriately processed by the beverage preparation machine. For example, the container requires the defined position or orientation such that an identification code can be read by the beverage preparation machine, or such that water can appropriately traverse the container for accordingly preparing the beverage from the ingredients provided inside of the container. An easy use of the container for an appropriate use in the beverage preparation machine is thus desired.

Separating the blank to form the container and in particular to form a complex shape of the container, in particular for convenient handling of the container, is not ecologically friendly. This is because the separation process results in that a certain and quite high percentage of the blank, i.e. of the roll material, remains in between the cut out blanks, out of which the container or the part of the container is manufactured. Consequently, this remaining or unused material leads to a significant amount of waste, thereby also increasing the costs of production.

Therefore, it is an object of the present invention to provide a container and a process for manufacturing a container, which overcome the aforementioned drawbacks. That is, it is in particular an object of the present invention to provide a container, which can be efficiently manufactured and at the same time facilitates an easy use in a beverage preparation machine.

These and other objects, which become apparent upon reading the following description, are solved by the subject-matter of the independent claims. The dependent claims refer to preferred embodiments of the invention.

SUMMARY OF THE INVENTION

According to a first aspect of the invention, a container is provided for use in a beverage preparation machine. The container comprises a sealed body for containing an ingredient for preparing a beverage such as a coffee or tea, the sealed body comprising a back part and a front part, which are sealed along one or more first side edges. The front part comprises one or more tabs integrally formed with the front part, wherein each of the one or more tabs has one or more second side edges, wherein at least one (or each) of the one or more second side edges (of the respective tab) is at least in part complementary formed to the one or more first side edges.

In the context of the present invention, a form is to be understood “complementary formed” to another form, when the forms can be connected to each other such that substantially no clearance is formed between the forms, e.g. when a convex form and a concave form are defined by substantially the same diameter.

The one or more second side edges may be formed by obtaining one or more further front parts of different containers, such as by obtaining one or more first side edges and/or one or more second side edges of the further front parts.

According to a second aspect of the invention, a container is provided for use in a beverage preparation machine. The container comprises a sealed body for containing an ingredient for preparing a beverage such as a coffee or tea, the sealed body comprising a back part and a front part, which are sealed along one or more first side edges. The front part comprises one or more tabs integrally formed with the front part, wherein each of the one or more tabs has one or more second side edges, wherein the one or more second side edges are formed by obtaining one or more further front parts of other containers.

In other words, the design of the container(s) according to the present invention facilitates that a plurality of such containers or front parts can be put together like a jigsaw puzzle, e.g. forming a single piece without any clearances defined by the connection between the front parts. Thereby, the container or front part can be produced with a reduced amount of waste. That is, a significantly increased amount of the material, which would remain as waste after obtaining the respective container or front part and at least one further container or front part, is now used for the one or more tabs. The one or more tabs in turn effect an easier use of the container, since the one or more tabs provide a structure for cooperating with the beverage preparation machine and/or with the user, e.g. for easier handling and/or processing of the container. Thereby, the container in particular provides a more efficient manufacturing, while at the same time providing an easier use of the container with respect to the beverage preparation machine.

The front part and the one or more further front parts may be obtained from the same blank. This increases the efficiency of manufacturing the container. Additionally or alternatively, the front part and the one or more further front parts may be identically formed. “Identically formed” is to be understood such that the front part and the one or more further front parts have the same form or shape, at least when viewed in a plan view of the front parts, which may be a viewing direction being perpendicular to a flat surface of the front parts or the blank, from which the front parts are obtained. This increases the efficiency of manufacturing the container.

The one or more tabs may include a handling tab for handling the container. The handling tab typically provides a surface adapted for being grasped by a user. The handling tab effects that a user can easily handle or (manually) manipulate the container, e.g. with respect to a beverage preparation machine, without touching or acting on the sealed body or ingredient contained in the sealed body. For example, the handling tab is provided such that a user can insert the container into the beverage machine and easily remove or withdraw the container from the beverage preparation machine for disposing of the container, e.g. since the beverage preparation machine does not include a trash bin for the container. When inserted in the beverage preparation machine, the handling tab may extent in a direction to an outside of the beverage preparation machine, so that a user can easily remove the container from the machine after use.

The one or more tabs may include an identification tab comprising (machine-readable) information, e.g. in the form of a code (2D-, 3D-, matrix-barcode, QR-code, RFID, etc.), for processing the container in a beverage preparation machine. The identification tab may bear the information, e.g. the information respectively code may be printed onto the identification tab. The information may include information relating to the ingredient of the container and/or information relating to process parameters for processing the container such as for processing the ingredients contained in the sealed body. The identification 30 tab therefore provides a surface, on which the information can be provided, so that there is in particular no need to provide the information on other parts of container, such as on the sealed body. Further, the identification tab provides a good visibility of the information for a reader of the beverage preparation machine. The reader of the beverage preparation machine is usually adapted to automatically read the information, when the information provided on the identification tab is in the field of view of the reader. Therefore, the identification tab effects a very easy reading of the information provided on the identification tab by the dedicated information reader of the beverage preparation machine. As such, the identification tab effects an easier use of the container in a beverage preparation machine.

Preferably, the one or more tabs are shaped to bring the container in a defined position and/or orientation in a beverage preparation machine. For example, at least one or each of the one or more tabs, in particular the one or more side edges of the respective tab, is at least in part shaped correspondingly to a part of the beverage preparation machine, thereby effecting the defined position and/or orientation with respect to the beverage preparation machine. In the defined position and/or orientation of the container, the container can be appropriately processed by the beverage preparation machine, and/or the information provided on the container, e.g. on the identification tab, can be appropriately read by the beverage preparation machine, and/or the handling tab extends in a direction for any easy removal of the container from the beverage preparation machine. Since a beverage preparation machine may require that the information to be read is always at the same place within the machine, i.e. in the field of view of the reader of the beverage preparation machine, the one or more tabs can effectively effect that the information provided on the tab is always in this place, when the container is used (inserted) in the beverage preparation machine.

The tabs may extent in different directions. Thus, it is effectively prevented that one of the tabs, e.g. the handling tab, interferes with a further one of the tabs, e.g. the identification tab, thereby increasing the ease-of-use of the container. Additionally or alternatively, the tabs may be arranged to be diametrically opposed. This provides, in particular, for a particularly easy use of the container, since due to the relatively great distance between the tabs it is prevented that the tabs interfere with one another.

The tabs may extent in a same plane. In other words, the tabs may be obtained from the same blank having a flat surface, wherein said flat surface substantially extents in only one plane. Therefore, the compactness of the container is increased.

At least one of the one or more second side edges may be a side edge being laterally provided with respect to the respective tab. Since the lateral side of the tab is usually the longest side of the respective tab, a relatively great amount of waste during obtaining the container can be reduced.

At least one of the one or more second side edges may be a side edge being provided at a distal end of the respective tab. Therefore, a relatively long tab can be provided, since, when two front parts are obtained from the same blank, the distal end corresponding to the first side edge can thus be formed by using the material extending up to the first side edge of the further front part. As such, the front part may comprise, for example, only one tab for fulfilling different functions, e.g. the function of both the handling tab and the information tab, i.e. of both handling the container, and providing information.

The one or more second side edges of one of the tabs may include a second side edge being complementary formed to a second side edge of a further one of the tabs. In other words, by obtaining a second side edge of one of the tabs, e.g. this second side edge being a distal end of this tab, at the same time a second side edge of a further tab, e.g. this (further) second side edge being also a distal end of this (further) tab, of a front part of another container can be obtained.

Therefore, a design of the container for more efficient manufacturing is provided. Additionally or alternatively, the one or more second side edges of the one or more tabs includes a second side edge being formed by obtaining one or more tabs of further front parts of other containers. Therefore, manufacturing of the container is more efficient.

At least one of the one or more second side edges may have a concave shape, wherein the one or more first side edges have thus a convex shape. These complementary shapes or forms of the first and second side edges are particularly advantageous for an efficient manufacturing of the container.

Each of the one or more tabs may have only three second side edges. These three second side edges may merge continuously or discontinuously with one another. Two of these second side edges may be laterally provided side edges of the respective tab, wherein the third of these second side edges is provided at the distal end of the respective tab. In one embodiment, each of the (three) second side edges of a respective tab is at least in part complementary formed to the one or more first side edges. Therefore, a particularly great amount of waste during manufacturing of the container can be reduced. According to this embodiment, a container with only one tab may be obtained. In another embodiment, only two of the second side edges of a respective tab, e.g. the laterally provided side edges, may be each at least in part complementary formed to the one or more first side edges, wherein, more preferably, the third of the second side edges of the respective tab, e.g. provided at the distal end, is at least in part complementary formed to the third of the second side edges of the respective other tab. Therefore, a particularly great amount of waste during manufacturing of the container can be reduced, while according to this embodiment a container with at least or only two tabs can be very efficiently obtained.

According to a third aspect of the invention, a process for obtaining one or more first front parts and (for obtaining) a second front part from a blank is provided. Each of the front parts may be a front part as previously described. Each front part is suitable for a container (e.g. as described above), wherein the container is adapted to be used in a beverage preparation machine, wherein the container comprises a sealed body for containing an ingredient for preparing a beverage, the sealed body comprising a back part and the respective front part. The process comprises the following steps: providing a blank for obtaining the front parts, obtaining the one or more first front parts from the blank, and obtaining the second front part from the blank such that the second front part comprises one or more tabs with each tab comprising one or more side edges, which one or more side edges are formed by obtaining the one or more first front parts from the blank. The “second front parts” may also refer to “the front parts”, wherein the “first front parts” may also refer to the “further front parts”.

The process may also include the step of sealing together the one or more first front parts and/or the second front parts with a respective back part, thereby forming a sealed body. The process may also include dosing of an ingredient (e.g., coffee or tea) for preparing a beverage, such that the respective sealed body contains the ingredient. Dosing may be before the respective sealing.

The above-described advantages with respect to the container apply likewise to the process of the invention. In particular, the process facilitates an efficient manufacturing of the one or more first front parts and the second front part with a significantly reduced amount of waste. In other words, the process uses the material, which would remain as waste material, e.g. when the front parts would be obtained without any tab, as the one or more tabs being integrally provided with the second front part. Thus, a very efficient production of the front part respectively container is achieved, while at the same time the front part respectively container can be more easily used by having the one or more tabs.

The front parts may be obtained by a separation process. Therefore, the front part is very efficiently obtained, in particular with a reduced amount of waste. In a possible embodiment, the front parts may be obtained by punching.

In the following, the invention is described exemplarily with reference to the enclosed figures, in which

FIG. 1 is a schematic plan (top) view of a front part of a container according to a first preferred embodiment;

FIG. 2 is a schematic plan view of a blank for obtaining a plurality of front parts according to the embodiment shown in FIG. 1;

FIG. 3 is a schematic plan (top) view of a front part of a container according to a second preferred embodiment;

FIG. 4 is a schematic plan view of a blank for obtaining a plurality of front parts according to the embodiment shown in FIG. 3;

FIG. 5 is a detailed view, showing how a front part according to the embodiment shown in FIG. 3 is obtained from the blank shown in FIG. 4; and

FIG. 6 is a plan view of the front part in FIG. 5 without the remaining blank.

In the figures, two preferred embodiments for a container 1 are shown. The container 1 is adapted for being used in a beverage preparation machine, e.g. in a beverage preparation machine of the “Nespresso professional” type. Therefore, the container 1 may be adapted to be traversed by a flow of (pressurized and/or heated) water. The beverage preparation machine may comprise a water tank, a heater for heating the water from the water tank, and a pump for pumping the heated water. The beverage preparation machine may also include a holder adapted for holding the container 1. For example, the holder is adapted to hold the container 1 in a position, in which the beverage preparation machine can produce a beverage from the container 1 by the (heated and/or pressurized) water. The container 1 is not limited to a specific container. For example, the container 1 may be a capsule or a pod.

The container 1 comprises a sealed body 2 for containing an ingredient for preparing a beverage. The ingredient may be, for example, (ground) coffee or tea (tea leaves, herbal tea, fruits, herbs, spices, etc.) or any other plant material suitable for preparing a beverage, e.g. by extraction. The ingredient may also include additives such as milk or sugar. The beverage to be prepared may therefore be, for example, a coffee or a tea.

The sealed body 2 comprises a front part 3 and a back part. In the figures, the back part is not shown, since the figures show a plan view, in which the viewing direction is perpendicular to a flat surface of the front part 3. The back part is provided on a rear side of the front part 3. The front part 3 and the back part are sealed at least along (only) one or more first side (or peripheral) edges 4. Thereby, the front part 3 and the back part delimit a (closed and/or internal) compartment, which contains the ingredient. Each of the one or more first side edges 4 may have a round or convex form (shape). In other examples, each of the one or more side edges 4 may also have a different shape, e.g. a straight, elliptical and/or polygonal shape. Sealing together the front part 3 and the back part may thus be in part along the one or more side edges 4 and in part on other parts of the front part 3 and back part so that a sealing path 5 is obtained, which is, for example, a closed sealing path 5. The sealing path 5 may have a shape corresponding to the one or more first side edges 4. For example, the sealing path 5 has a round shape, in particular in the form of a (closed) circle. In other examples, the sealing path 5 may also have a polygonal form. Sealing may be effected by a heat sealer. In other examples, an additional sealing element, e.g. an adhesive bond element such as a glue, may be provided for sealing together the front part 3 and the back part.

The front part 3 and/or the back part may be respectively provided in a formed state, i.e. having a three-dimensional extension. For example, the front part 3 and/or the back part may be initially provided in a substantially flat state, in which the respective part has substantially only a two-dimension extension. The front part 3 and/or the back part may be brought from the flat state into the formed state by a forming process. The form of the front part 3 and/or the back part thus defines the spatial extent of the compartment defined by the front part 3 and back part.

The back part may be adapted for injecting water into the container 1, i.e. in the compartment defined by the front part 3 and the back part. For example, the back part may be designed to be pierced by a needle, which needle thus injects water into the compartment. The front part 3 may be adapted to discharge water from the compartment. That is, the water enters the compartment via the back part, comes into contact with the ingredients inside of the compartment, thereby e.g. extracting soluble compounds or flavors from the ingredients, and is finally discharged by way of the front part 3 for dispensing the beverage. The front part 3 may comprise a filter for preventing particles of the ingredient to flow downstream of the front part 3. The front part 3 may function as the filter. Alternatively, the filter may be provided separately with respect to the front part 3, e.g. downstream or upstream of the front part 3 with respect to the flow of discharging water.

In the embodiment shown in FIGS. 1 and 2, the front part 3 comprises only one tab 11. The tab 11 is integrally formed with the front part 3, so that the front part 3 and the tab 11 are obtained from the same blank (raw material). The tab ii extends to an outside of the front part 3 or container 1. For example, the tab 11 may extend from the sealing path 5, preferably such that the proximal end of the tab 11 is provided at the sealing path 5 or the sealing path 5 extends over the proximal end of the tab 11. The tab 11 may extent in a substantially flat manner, i.e. in substantially only one extension plane and with only one (relatively thin) thickness. The tab 11 may comprise a surface, wherein the surface is, for example, substantially parallel to the main extension plane of the front part 3.

The tab 11 may be a handling tab for handling the container 1, in particular for inserting the container 1 into the beverage preparation machine and for removing the container 1 from the beverage preparation machine. Therefore, the surface of the tab 11 may be adapted for being grasped by a user. Thus, the surface may be provided such that grasping the tab 11 or the surface does not interfere with the compartment defined by the back part and front part 3. For example, the surface comprises a defined or undefined structure, which aids in grasping the tab 11. The surface may be roughened so that a particularly easy handling of the tab 11 and, thus, of the front part 3 and container 1 is possible.

Additionally or alternatively, the tab 11 may be an identification tab. The tab 11 thus comprises information for processing the container 1 in the beverage preparation machine. The process parameters may refer, for example, to a water pressure and/or a water temperature and/or a filling volume of the beverage to be prepared. The information may be provided in the form of a code. For example, the tab 11 or the surface of the tab 11 may comprise a machine-readable code comprising the information, wherein the machine-readable code can be read by a dedicated reader in the beverage preparation machine. The machine readable code may be an RFID tag and/or a barcode, e.g. a 2D-, 3D-, matrix-, or QR-barcode. Thus, the surface of the tab 11 may both be provided for handling the container 1 and for bearing information, thereby being both a handling tab and an identification tab.

The tab 11 may be shaped to bring the container 1 in a defined position and/or orientation in a beverage preparation machine. For example, the tab 11 or a structure of the tab 11, e.g. the below described second side edges, is shaped correspondingly to a part of the beverage preparation machine such as of the holder of the beverage preparation machine. As such, the corresponding connection or engagement between the (structure of) the tab 11 and the beverage preparation machine brings the container 1 in the defined position and/or orientation. In the defined position and/or orientation, the beverage preparation machine can appropriately process the container 1, e.g. the beverage preparation machine can appropriately read the information provided on the tab 11 and/or inject water into the container 1 for preparing the beverage. Thus, with the tab 11 an erroneous operation of the beverage preparation machine with the container 1 can be effectively prevented.

The tab 11 comprises a plurality of second side (or peripheral) edges 12, 13, 14. In the exemplary embodiment shown in FIGS. 1 and 2, the tab 11 comprises only three second side edges 12, 13, 14. The second side edges 12, 13, 14 delimit the tab 11 or the surface of the tab 11. The second side edges 12, 13 are side edges, which are laterally provided with respect to the tab 11. That is, each of the second side edges 12, 13 extend from the proximal end of the tab 11 to the distal end of the tab 11. For example, each of the second side edges 12, 13 merges continuously with the first side edge 4 or, if present, with a respective one of a plurality of first side edges 4. The second side edge 14 is provided at the distal end of the tab 11. As exemplarily shown in FIG. 1, the second side edge 14 may merge discontinuously with the laterally provided second side edges 12, 13, respectively. In other examples, the second side edge 14 may also merge continuously with the laterally provided side edges 12, 13. For example, the second side edges 12, 13, 14 may form a single second side edge, which delimits the (surface of the) tab 11.

According to the invention, at least one of the second side edges 12, 13, 14 is at least in part complementary formed to the one or more first side edges 4. Due to this complementary form of the first side edge 4 on the one side and the at least one (or each) of the second side edges 12, 13, 14 on the other side, the container 1 and in particular the front part 3 can be produced with a reduced amount of waste, since the material, which would be actually waste material, is now used for obtaining the tab 11. More specifically, and with reference to FIG. 2, the tab 11, i.e. the second side edges 12, 13, 14, may be obtained or formed by obtaining, e.g. cutting or separating such as punching, one or more further front parts 3′ of other containers. As apparent from FIG. 2, the front part 3 and the further front parts 3′ may be obtained from a same blank 30 and/or may be identically formed, when viewed in a plan view of the blank 30 or the front parts 3, 3′. The blank 30 may be provided in the form of having a (single) flat surface, and/or may be from a roll of material.

In the exemplary embodiment shown in FIGS. 1 and 2, each of the second side edges 12, 13, 14 of the tab 11 is at least in part or entirely complementary formed to the first side edge 4. As apparent from FIG. 2, an area or a region of the blank 30 may be delimited by three front parts 3′ (“first front parts”) to be obtained from the blank 30; for example, the area may be between the circular shapes of the front parts 3, 3′. These three front parts 3′ are obtained from the blank 30, e.g. by separating at least along the respective first side edge 4, such that the before-mentioned area or region is separated from these three front parts 3′, but still integrally formed with another front part 3 (“second front part”) to be obtained from the blank 30. Thus, the area or region—previously delimited by the three (first) front parts 3′ to be obtained from the blank 30—becomes the tab 11 being integrally formed with the remaining (second) front part 3. Thereby, each of the second side edges 12, 13, 14 of the tab 11 of the second front part 3 is complementary formed to the first side edge 4 of the first three front parts 3, thereby resulting in substantially no waste for obtaining these four front parts 3, 3′.

The second side edges 12, 13, 14 are not limited to a specific shape as long as at least one of these second side edges 12, 13, 14 is complementary formed to the first side edge 4, thereby resulting in a reduced amount of waste. A form is to be understood “complementary formed” to another form, when the forms can be connected, or cooperate, with each other such that substantially no clearance is formed between the forms. For example, in case the complementary forms are round shaped, the complementary forms have substantially equal diameters. As shown in FIGS. 1 and 2, each of the second side edges 12, 13, 14 has preferably a concave shape, since the first side edge 4 has a convex shape. In other embodiments, the second side edges 12, 13, 14 may also have a different shape, e.g. a polygonal, rectangular, or straight shape. With such a design, a plurality of containers 1 respectively front parts 3 can be put together like a jigsaw puzzle, thereby forming a single surface (when viewed in a plan view of this surface) without any clearances formed by putting together the front parts 3, as shown in FIG. 2.

In FIGS. 3-6, a container 1 according to a second preferred embodiment is shown. The container 1 according to the second preferred embodiment substantially corresponds to the container 1 according to the first embodiment as described above, unless otherwise specified in the following.

The container 1 according to the second embodiment differs from the container 1 according to the first embodiment in particular in that the container 1, i.e. its front part 3, comprises a plurality of tabs, namely the tab 11 and a further tab 21. In other embodiments, the front part 3 may also comprise more than two tabs. The further tab 21 substantially corresponds to the tab 11 so that the description of the tab 11 applies correspondingly to the further tab 21, unless otherwise stated. Therefore, the further tab 21 also includes one or more second side edges 22, 23, 24, out of which the side edges 22, 23 are laterally provided side edges, and the side edge 24 is provided at a distal end of the further tab 21. The further tab 11 may be used for a different function than the tab 11. For example, the tab 11 is only used as the handling tab, wherein, additionally or alternatively, the further tab 21 is only used as the identification tab.

The tabs 11, 21 may extend in different directions and/or in the same plane. As apparent from, in particular, FIG. 3, the tabs 11, 21 may be arranged to be diametrically opposed. The tabs 11, 21 may be arranged such that by handling the container 1 by way of the tab 11 to be put inside of the beverage preparation machine, the further tab 21 is brought into a position and/or orientation, in which the beverage preparation machine can read the information provided on the further tab 21. The further tab 21 may be, as apparent from FIG. 3, shorter than the tab 11 so that in particular the surface of the further tab 21 (i.e. the surface, which can be seen in the plan view of the front part 3) is smaller than the surface of the tab 21. For example, the surface of the further tab 21 may be such that the surface substantially only comprises the information (e.g. a barcode), i.e. the information covers the entire surface of the further tab 21.

The second embodiment of the container 1 also differs from the first embodiment of the container 1 in that one of the second side edges of each of the tabs 11, 21 is (at least in part or entirely) complementary formed to a second side edge of the respective other one of the tabs 11, 21. As apparent from, for example, FIGS. 3 and 5, the second side edge 14 a (i.e. the third side edge 14A), which is provided at the distal end of the tab 11, is complementary formed to the (third) second side edge 24 of the further tab 21, which is also provided at the distal end of the further tab 21. The respective other two second side edges 12, 13, 22, 23 are each at least in part complementary formed to the one or more first side edges 4.

As apparent from FIG. 4 and, in particular, FIG. 5, an area (or a region) of the blank 30 is delimited by two front parts 3′ (“first front parts”) to be obtained from the blank 30; for example, the area may be between the circular shapes of the front parts 3, 3′. These two front parts 3′ are obtained from the blank 30, e.g. by separating at least along the respective first side edge(s) 4. The before-mentioned area is also separated along the second side edge 24—and thus along the second side edge 14A—such that this area is separated in a first part and a second part. The first part of this area remains integrally formed with a (“second”) front part 3 (but separated from the respective other front parts), thereby forming the further tab 21 of this front part 3. The second part of this area remains integrally formed with a further (“second”) front part 3, but separated from the respective other front parts, thereby forming the tab 11 of this further front part 3. Thus, the area or region—previously delimited by the two (“first”) front parts 3′ to be obtained from the blank 30—becomes the tab ii and the further tab 21 being integrally formed with a (“second”) front part 3 and a further (“second”) front part 3, respectively. Thereby, for obtaining the tabs 11, 21 of a plurality of front parts, substantially no waste is generated. Further, with the second side edges 12, 13 and the second side edges 22, 23 being complementary formed to the first side edges 4 of the respective other front parts 3, waste during manufacturing is significantly reduced.

The second side edges 14A, 24 are not limited to a specific shape as long as they are complementary formed to one another, thereby resulting in a reduced amount of waste. As shown in FIGS. 3 and 5, the second side edge 14A has preferably a convex (e.g. round) shape, and the second side edge 24 has thus a concave (e.g. round) shape. In other embodiments, the second side edges 14A, 24 may also have a different shape, e.g. a polygonal, rectangular, and/or straight shape.

The container 1 is not limited to a specific material. For example, the (entire) container 1 or at least the front part 3 and/or back part is made of a flexible or semi-flexible material and/or of a material comprising plastic, paper, cardboard, aluminum, and/or a multilayer laminate. Additionally or alternatively, the (entire) container 1 or at least the front part 3 and/or the back part may be made of a biodegradable and/or compostable (home compostable or industrially compastable) material, e.g. a material comprising a compostable polymer, paper, and/or cellulose. A material is to be understood as “compostable” or “biodegradable” when the material fulfills the requirements established by the European Norm EN 13431 (“Packaging—Requirements for packaging recoverable through composting and biodegradation—Test scheme and evaluation criteria for the final acceptance of packaging”).

It should be clear to a skilled person that the embodiments shown in the figures are only preferred embodiments, but that, however, also other designs of a container 1 can be used.
