packaging system

description

The invention relates to a packaging system for pourable liquids, powders and granules, in particular pourable food.

From the prior art containers are known, which are usually made of several different materials, or have been designed so expensive that a commercial use for cost reasons is not possible. Thus, DE 69910428 T2 describes a packaging container made of polyethylene and aluminum with a laminated tubular multilayer packaging material.

Since separation of a packaging container made of a plurality of different materials into its base materials is extremely laborious for recycling, there is a great need to provide packaging containers made of only a very few materials and components which are easy to separate from each other This way, a quick and resource-saving return of the respective components in the recycling loop to allow. It must be ensured that an alternative fits into the market and is not more expensive than previous systems.

A further problem with prior art packaging containers is that when the package is opened, air flows into the package and the contents of the packaging container come into contact with the surrounding air, which in particular in the case of liquid foods, brings about various chemical processes and can lead to a reduced shelf life and thus to a faster perishability of the liquid content.

CONFIRMATION COPY Although there are packages that fold when emptied and thus counteract the entry of air, but these are again poorly stackable, consume unnecessarily much space during transport and are insufficiently stable against external pressure. Thus, EP 0 746 507 B1 discloses a form of bag-like packaging containers, which consist only of the flexible bag and have no outer jacket, are poorly stackable and insufficiently stable against external pressure, since they are loose in the carton and thereby take no load, but the Prevent entry of air into the container.

The object of the present invention is therefore to provide a packaging system for pourable liquids, powders and granules, in particular pourable foodstuffs, which after use enables a simple recycling into the recycling loop and potentially a more cost-effective production. In addition, in some embodiments, the durability of the contents of the packaging container is to be increased. In this way, the known problems of packaging containers according to the prior art should be overcome. This object is achieved by the technical teaching of the independent claims. Advantageous embodiments of the invention are specified in the dependent claims, the description, the figures and the examples. In a first embodiment, the object underlying the invention is achieved by a packaging container for pourable liquids, powders and granules, which has an outer shell, an inner flexible bag with an outlet opening and an outlet part connected to the inner flexible bag, wherein the inner flexible bag is connected to the outlet part via a weld, via an adhesive connection or by casting, and wherein the outlet part connected to the outer jacket via a weld, an adhesive connection, a punching operation, a connector, a clamping device or via the introduction of a guide wire is. The packaging container according to the invention preferably consists of an outer jacket, which encloses the inner bag in parts or all, preferably a cardboard or a hard shell but can also be made of fabric or other natural materials and plastics, an inner flexible bag with an outlet and from a consists with him connected outlet part. The inner flexible bag can either be separated from the outer shell by pulling on the outlet part connected to it, or it can be separated or removed by opening the hard shell or by means of special tearing or separating mechanisms.

Preferably, the outlet part is integrally connected to the flexible bag, in particular welded. This is an advantage over the prior art in that the bag can indeed be cut open, but does not necessarily have to be cut open. Moreover, as a result of this, a clear mechanism is predetermined in a self-cutting variant of the packaging container so that the slicing process can take place in a controlled manner. This is not possible in the prior art. Therefore, the outlet part advantageously also has no further sealing devices, such as sealing ribs or sealing rings, which as a rule can only lead to leaks. The preferred one-piece design of the flexible bag with the outlet part makes such predetermined breaking points as further sealing devices superfluous.

The outlet part can preferably be inserted into at least one rail, which is arranged on the outer jacket. This can ensure that the outlet part is firmly seated and, for example, does not rotate when it is turned on. Advantageously, the rail is not round, but particularly preferably designed rectangular, which can be prevented any rotational movement of Auslasteilils. The outlet part is advantageously shaped so that it can engage complementary in the rails of the outer shell.

Advantageously, no valve is provided in the region of the outlet opening. This has the advantage that the packaging container according to the invention can be made much cheaper and easier. In the prior art is For example, a valve is needed to prevent the leakage of liquids and prevent after pouring that contaminated with germs surrounding air into the container. The packaging container of the present invention has the advantage that dispensing without subsequent inflow of germ-laden air is possible even without a valve, since the flexible inner bag collapses during pouring and therefore no negative pressure is created in the packaging container, which could provide an inflow germinated air.

The wall thickness of the outer jacket is advantageously in a range of 0.1 to 2 mm, in particular in a range of 0.15 to 1 mm. If the wall thickness is below this range, there is a risk that the packaging container will be slightly pressed when gripping the packaging container. If the wall thickness is above this range, the container becomes heavier and more expensive due to the greater material thickness.

The wall thickness of the flexible bag is advantageously in a range of 0.02 to 0.5 mm. Below this range, it may be easier to cause injury to the bag due to mechanical influences and thus to a leak. Above this range, it may happen that the higher wall thickness and thus the greater rigidity of the flexible bag prevents complete emptying, for example by collapsing the bag.

The packaging container preferably has a size in a range of 5 to 50 cm, calculated on the basis of the two points of the packaging container, which are furthest apart. Thus, the packaging container is particularly well suited for products such as food or cosmetics intended for end users.

The inner flexible bag preferably has between 2 to 3 layers of plastic or metal. These layers are preferably laminated or laminated. This can prevent the layers move against each other in a partially empty bag and impede the emptying. Advantageously, the outlet part is in direct physical contact with the outer shell or with the shell integrally formed rails. This has the particular advantage that, in contrast to solutions from the prior art, an additional component such as a holder for the outlet opening, which would have to be used only in the outer shell, is not necessary. This can prevent leaks and reduce manufacturing costs. On the side opposite the outlet opening, the flexible bag preferably has a molded-on rigid component which has a diameter at least at one point which is larger than the outlet opening. This can prevent the flexible bag from pouring out of the contents, such as a liquid of the bags, from the outlet opening.

The material of the outer shell is preferably cardboard or cardboard or a plastic. The outer shell preferably has no or no closed coating or foil on its inside which would make the inside leak-proof to liquids. This has the advantage that over the known containers of the prior art, a further processing step and also costs can be saved. Furthermore, the outer jacket can be designed, for example, in this way continuously for air or liquids, so that mold formation can be prevented in the interior of the outer shell between the flexible bag and the outer jacket.

Preferably, the packaging container for pourable liquids, powders and granules, comprising an inner flexible bag having an outlet opening, an outlet part and an outer jacket, the inner flexible bag being fixedly connected to the outlet part, the outer jacket enclosing the inner flexible bag inner flexible bag is separably connected via the outlet part used in a recess with the outer shell, the outer shell consists of at least two hinged hard shells, which are hinged together via at least one hinge joint and at least have a releasable locking mechanism.

For example, the invention may be a packaging container having an inner flexible bag made of a flexible or flexible film, a laminated fabric or a laminated film, wherein the inner flexible bag may also be made of natural materials such as corn. By way of example, the inner flexible bag is itself or after a corresponding treatment relatively dense or dense against the exchange of gases or liquids. Tight or relatively dense against the exchange of gases or liquids means that for a 1 L packaging container filled with one liter of water within 170 days storage at 23 ° C and normal humidity and air pressure no more than 0.3 vol .-% of water escape the flexible bag through the bag material. In the case of special requirements, however, it is also possible to choose a film in which the barrier requirements for the filling material are specially set and, as a result, perhaps even a desired air exchange can and should take place. These flexible properties of the inner bag are a great advantage especially in production. For example, the use of single materials makes exchanges very easy and does not have to be considered in production processes beforehand. This also saves storage costs.

The inner flexible bag is preferably fixedly connected to the outlet part. This makes targeted pouring possible. The connection can be made via a weld, via an adhesive bond, by jamming, by casting or by introducing a guidewire or strip of other materials. Preferably, the weld is produced by laser welding.

The outlet portion may be in the form of a screw cap, lid, resealable cap, valve, or suitable plug or cork.

The outlet part is preferably placed in the lower or upper third of the packaging. attached.

The outer jacket, for example, partially or completely surrounds the inner flexible bag except for the area of the outlet part. Accordingly, in this region of the outer shell, for example, a recess attached.

At the area around this recess in the outer shell, the outlet part can be fastened with the inner flexible bag attached thereto. The connection can be made via a weld, via an adhesive connection, a punching process, a plug connection, a clamping device or via the introduction of a guide wire, also from other materials. It may also be that the tear seam is attached to a very different location by certain clamping connections (see figures) and can be easily separated from the inner bag by dissolving this tear seam then the container. So this version can also be applied.

Preferably, the connection via an adhesive connection or a clamping device. On the one hand, the connection must ensure the required minimum degree of stability for the packaging container; on the other hand, when the components of the packaging container are disposed of, this connection must be easily separable by pulling on the outlet part with little effort.

This inner flexible bag is preferably not fully connected to the outer jacket. The outer jacket can take over the function of a former as well as a stability transmitter and can additionally serve to print advertising and product information.

A non-full-surface bonding of the inner bag and the outer jacket, preferably a punctiform and / or linear adhesive bonding or jamming, jamming or pinching. In some preferred embodiments, the inner flexible pouch is punctiform or linearly connected to the outer shell at 1-20 points. It can be unfortunate that the bag does not match the outer shell is connected and the stability, for example, alone by the shape of the bag is formed, such as the gusseted bag, which can be ideal in cuboid container insert without twisting or collapse. A preferred embodiment of the inner flexible bag is the tubular bag. This tubular bag need not necessarily have the shape of a tube, but it is also possible to give the tub boot a certain shape, so that the tubular bag approximately the shape of a cylinder, cube, cuboid, tetrahedron, polygon container, star, triangle, heart , Wedge, tube, oval cylinder, bag, tube, bottle, triangular prism, pyramid or ball and thus conforms to the contours on the inside of the outer jacket, which has a comparable shape or forms some surfaces of a body of comparable shape. Preferably, the inner flexible bag is in the fully filled state of the inside of the outer shell very close. The inner flexible bag is preferably made of only one material or composite material such as polyethylene, polyethylene terephthalate, polypropylene, polyesters, polyurethanes and multi-ply materials of the aforementioned materials or other common plastics for storing liquids and especially foods. The material for the flexible bag thus preferably consists of a plastic film, which can be constructed from up to 7 layers of different materials. However, these plastic bags may also have been steamed with alumina, silica and / or other barrier materials. Depending on the content of the flexible bag, it must protect the contents from water leakage or C0 ₂ leakage, be acid resistant, resistant to alcohol or protected from sunlight, so that sunlight-repellent layers, sunlight-reflecting layers or colored flexible bags can be used.

The packaging container has an outlet part or a pouring opening, which is located, for example, at a position which makes it possible to pour out substantially the entire contents of the package. The outlet part can also be preferably provided with a valve which only allows the outlet of the contents of the packaging container, but no air, gas or liquid in opposite direction enters the inner bag. The outlet part is preferably located at a corner or at an edge or an optimal point given by the carton or bag shape of the bottom or a side part and may also be in the middle of each side of the package. The advantage of this embodiment is that when discharging liquid, powder or granules no or very little air enters the interior of the packaging container and so the located in the interior liquid or the powder or granules, and any other goods, not or only very little contact with air. This prevents oxidation processes, which ensures a longer shelf life of the food in the case of filling the packaging container with food. By means of a valve built into the outlet part and the flexible packaging of the packaging container, the inner flexible bag contracts due to the liquid weight and the vacuum created during emptying. Due to the elastic construction, the inner flexible bag does not or only very slightly fill with air, which protects the bag contents and leads to a longer shelf life of the bag contents.

In order to discharge the liquid from the packaging container, the packaging container is provided with a spout opening which may or may not be equipped with a valve. This valve, which can also be used as spout or portioner, must prevent that after pouring the liquid or the solid neither oxygen can penetrate into the packaging container or other liquid or powder can flow out of the bag.

An example of a valve usable in accordance with the invention is shown in FIGS. 4-7. FIGS. 4 to 7 show the structure of the valve, which can also be provided with a lid by means of a screw cap. The valve has openings to exit the bag contents. FIG. 7 shows an embodiment of a valve with three openings, wherein a different number of openings is also possible. In the middle of the valve is a pin on which a rubber ring as shown in Figures 4, 6 and 7, is plugged. The rubber ring allows only the outlet of the contents of the flexible bag from the inside out through the three openings, whereby the rubber ring bulges outward through the pressure exerted on the bag contents and lets the contents of the bag emerge laterally past the rubber ring. As soon as pressure is no longer exerted on the contents of the bag due to the weight of the fluid, a negative pressure is created in the flexible bag, which causes the rubber ring in the valve to be pulled inwards, thereby closing the three openings in the valve.

As soon as the weight of the filling material is no longer sufficient to overcome the tension of the rubber valve and then there is only so much contents in the container that an early final emptying is close in time, for example, on a small nipple, the rubber valve can be removed and the outlet is free throughout for the final emptying.

Other possible forms of a valve could consist of a tubular outlet, wherein the tube has a thickening at a location in which a movable ball is enclosed so that the ball opens the tube facing the packaging container when pressure is applied to the bag contents that the bag can be emptied and pressed in pressure from the outside into the tube or due to negative pressure in the flexible bag, the ball in the tube in the direction of the bag and closes extending in the direction of the bag tube part of the spout.

In principle, the present invention also works without a valve, as long as the flexible bag is not actively re-expanded during emptying of the flexible bag before closing the outlet part, so that air, gas or liquid can penetrate into the bag.

In conventional packaging containers for liquid foods from the prior art, such as the known Tetra-Pak ^®, is used mostly on the basis of a carton, a lot of material technology, the same rigid material used on all surfaces of the packaging container construction. The use of several relatively rigid materials inevitably results in a rigid and inflexible construction. Due to the lack of elasticity of the packaging In addition, air and a pouring spout attached to the upper part of the pouring air flows into the container, causing the contents to come into contact with air and, as a result, spoil the contents more quickly. On the other hand, packaging which does not have a multi-layered construction according to the Tetra- ^Pak® principle and which is glued together over its entire surface, however, exhibits poor stackability, bursts more easily or loses its stability during emptying.

Under stackability is understood that you can put at least 3 pallets, each with 11 layers of fully filled packaging container without Verpackungsumkarton each other without the stack collapses.

The present invention overcomes these disadvantages known from the prior art. In particular, easily recyclable, stable and stackable packaging containers are provided, which moreover can be easily and completely emptied and, even without a valve, prevent the entry of air into the inner bag during emptying. The packaging containers of this embodiment according to the invention preferably consist of only three materials (apart from the adhesive), namely preferably a plastic for the inner flexible bag, a plastic for the outlet part and a cardboard, plastic or other, for example, natural materials for the outer jacket.

The aim of the invention is to allow easy separation of the various components of the packaging container, on the one hand the outer shell, on the other hand, the inner flexible bag with the outlet part. After use of the packaging container, the user, another person or a similar device in this embodiment can pull away from the outlet part in the direction perpendicular to the surface in which the outlet part is located. As a result, the optional punctiform or linear connection of the inner flexible bag with the outer shell is optionally dissolved. In any case, the outlet part is thereby completely released from its connection with the section located around the recess in the outer jacket. This is easily possible according to the invention with a small amount of force. This allows the outflow part and the inner flexible bag attached thereto to be pulled out through the recess in this way. After separation, these two components can be disposed of separately or recycled. According to the invention such disposal in a completely empty, partially emptied, full or never filled state is possible.

In this way, eliminates a costly material separation, as is often required in the packaging for example milk in the prior art.

The packaging container presented here has an inner flexible bag and an outer jacket and preferably has a square or a rectangular or even other shape with a bottom surface, up to a top surface, up to two side surfaces, a front surface and a back surface. In principle, the invention is not limited to certain types of packaging, so that more unusual shapes such as heart, star, tetrahedron, pyramid, wedge, ball or the like can be used, the cubic or cuboid shape are preferred. Alternatively, the outer jacket may also be made of glass and bottle-shaped. An advantage of this variant is that this cleaning of the bottles is eliminated and only the inner bag must be cleaned food clean.

Another preferred form of packaging container is the triangular prism. This preferred form of packaging container has an outer shell forming the three side surfaces of the triangular prism. Within the shell is a preferably cylindrical tubular bag or a tubular bag with a shape that also approximately corresponds to a triangular prism.

The outer jacket in these embodiments, preferably a paperboard or a plastic, may be of a rectangular matrix which is correspondingly folded and bonded or glued along an overlapping part will be formed. The triangular prism preferably has either three side surfaces of equal size and an equilateral triangle (a = b = c) or two equally sized side surfaces and an isosceles triangle (a = bc) as the base.

Some embodiments of the outer shell can be made in accordance with the invention so strong that they are also suitable for the use of carbonated drinks in the inner flexible bag. Over time, CO ₂ released over time can build up a pressure in the inner flexible bag, which can lead to a significant volume increase of the inner flexible bag. The resulting from the increase in volume of the inner flexible bag pressure on the outer shell this can withstand by its sufficient strength.

Another embodiment relates to a cylindrical outer shell having an inner flexible bag secured therein which is filled with granules of household chemicals such as drain cleaners. According to the invention, the solid outer shell and the inner flexible bag can be disposed of separately or recycled in this way. In further embodiments, it is also possible to use an inner flexible bag whose volume in the filled state is significantly smaller than the outer jacket. If this small-volume inner flexible bag collapses or moves improperly in the outer jacket upon removal of the contents, this small-volume inner flexible bag can be attached to the outer jacket via a special holder. According to the invention, adhesive dots or strips can also be used here, or a correspondingly large hooking device. As a result, for example, creates an insulating layer of air between the inner bag and the outer container, which keeps the contents longer cool or longer warm.

At the top of the packaging container, an outlet may optionally be located with a valve. Another preferred location for mounting the outlet is the upper portion of an edge between two side surfaces. The outlet in the packaging containers according to the invention is shown in FIGS. 6 and 7. The outlet may have an external thread to fire the outlet by means of a plug.

Figure 4 shows an outlet with an internal valve which allows only the exit of the contents of the inner bag, but not the entry of air and liquid. The outer shell of the packaging container can be made of cardboard, cardboard, paper, tissue, edible materials such as corn or soybeans, bamboo, wood, plastic, plastic, cellulose, glass, a natural material, a Textilmateri- al, leather, a composite material, metal or a metal alloy, cardboard, cardboard and plastic are preferred and cardboard is particularly preferred. It is preferred if only one material is used for the outer jacket. Furthermore, the outer jacket is preferably not laminated, non-laminated, not multi-layered, contains no aluminum foil and is not fully bonded or bonded to the material containing the pourable liquid or the pourable solid. In addition, the outer jacket is preferably produced from a folding pattern. It is not necessary to connect two or more items together to obtain the outer shell.

The compound preferably bonding of the inner flexible bag with the outer jacket can be applied selectively and / or as a strip or tape so that the packaging container receives the necessary stability, but can also be easily separated from the bag to be disposed of separately can. Combinations of punkformigen bonds with linear or strip-shaped or circular bonds can be applied. These 1 - 20 splices are adhesive surfaces of more than 4 mm ² each. Instead of these up to 20 large-area splices also several hundred or even several thousand small-area splices can be used, which then preferably distribute evenly or according to a specific pattern on the board surface. The kind and The design of the individual adhesive surfaces is irrelevant, it is important, however, that a full-surface bonding is avoided and preferably the bonded surface significantly less than 50% of the total inner cardboard surface, preferably less than 40% of the total inner cardboard surface, more preferably less than 30% of the total inner cardboard surface and more preferably less than 20% of the total cardboard inside area.

It is essential that preferably no full-surface bonding takes place, wherein full surface bonding of an area of 50% and more is already understood.

Instead of or in addition to the spot bonding, a linear bonding can take place, which can run, for example, along the edges as well as on the surfaces. The bond lines can be horizontal or vertical or oblique, rectilinear, zigzag-shaped or wavy or even subject to no geometry.

The individual lines can be arranged parallel to one another, converging or without geometry, and can extend along the side surface, be continuous or interrupted, and can also be supplemented by punctiform adhesions.

It is preferred that the surface to which the above-described punctiform or linear bonding has been applied is the surface opposite the inside of the outlet part.

This type of punctiform and / or linear bonding differs significantly from a bonding of packaging containers from the prior art. For example, the Tetra-Pak ^® uses full-surface bonding. The packaging container according to the invention thus avoids this known disadvantage by saving adhesive resources and therefore leads to easily separable material combinations and fixations. Also, the packaging container is awarded a better recycling property, since at a selective bonding of the cardboard separated from the packaging container easier can be.

In a further preferred embodiment, depending on the fill level of the inner flexible bag, the bond can be successively released or successively released, whereby the inner flexible bag is not kept mechanically open, but can fold or roll up better and yet not adversely affect the stability of the entire packaging container is impaired by the reduced bond area, since the level and thus the mass of liquid or solid in the inner bag has become smaller and the remaining adhesive surface ensures the necessary stability.

Particularly important in the case of the packaging containers according to the invention is that they are stackable and have a dimensional stability which is sufficient to allow stacking of the packaging container, which reduces the space requirement to a minimum and saves transport costs.

Because of the very good stability and the very good stackability packaging containers in the form of a triangular prism are also preferred. Another important aspect is the recyclability of the materials that make up the packaging container according to the invention. Through the use of only three materials (cardboard and two plastics) better recycling properties over packaging containers from the prior art, which are filled with liquid or powdered food, achieved. It should be emphasized that the packaging container according to the invention does not consist of a composite material, as used in packaging containers of the prior art. Although the inner flexible bag may consist of several materials or layers of material, which need not be separated and can be recycled together. Often, the plastic outlet can be disposed of together with the inner flexible bag.

By using only slightly different materials is with the Packaging container according to the invention for particular liquid or powdery food not only provided a packaging container, which can be very well introduced into the recycling cycle, but it can also be a much cheaper production of the inventive packaging container can be achieved. Preferably, only one material or composite material is used for the inner flexible bag and also only one material for the outer jacket. After separation of the outer jacket and inner bag, two valuable substances are obtained, namely plastic and, as a rule, cardboard, which can be supplied to two recycling circuits. Apart from the adhesive and the outlet part of the packaging container according to the invention thus preferably consists of only two materials or types of material. These two materials or types of material are preferably a plastic and a cardboard. This favorable combination of features of the packaging container presented here is surprising and gives the packaging container according to the invention superior functional properties over packaging containers produced according to the prior art. The packaging container according to the invention is stackable and provides optimum space utilization, is very easy to recycle, can be completely emptied and prevents the entry of air or liquid into the container, whereby the content remains longer lasting.

Thus, the present invention relates to packaging containers preferably for liquid food, in which the packaging container preferably does not fill with air when emptying. In addition, it is advantageous if the inner bag is preformed in the form of the outer jacket, ie in the form of the packaging container and thus in the fully filled state has a cuboid shape, cube shape, tetrahedral shape, pyramid shape, wedge shape, prism shape, etc. Finally is essential to the invention that there is no full-surface bonding or connection of the inner bag and outer jacket, coat and bag are not laminated together or that the bag forming material is not an inner layer of the outer shell and the material forming the bag easily from the consumer outer jacket can be separated. In addition, the present invention relates to a method for the separate disposal of inner flexible bag and outer jacket, comprising the following steps:

a) providing a packaging container according to one of the preceding claims;

b) detaching the outlet part and the inner flexible bag attached thereto from the outer shell by pulling on the outlet part; c) pulling the Auslassteiles and attached to him inner flexible bag from the outer shell, and

d) separate disposal of the inner flexible bag with attached to him outlet part and the outer shell.

Furthermore, the present invention also includes a method for producing and filling a packaging container as described above, comprising the following steps:

a) providing a filled, partially filled or unfilled inner flexible bag having an outlet opening, an outer shell and an outlet part;

b) firmly connecting the outlet part to the outlet opening of the inner flexible bag;

c) introducing the composite of outlet part and inner flexible bag in the outer shell, wherein the outlet part comes to rest in the region of the recess of the outer shell;

d) dot-shaped or line-shaped fastening of the inner flexible bag at 1 to 20 points with the inside of the outer shell; e) attaching the Auslassteiles in the region of the recess of the outer shell.

Following the procedure described above, the following step can optionally also be added: f) If the inner flexible bag was not filled or partially filled in step a), completely or partially fill the packaging container over the outlet part. In a further preferred embodiment, an optional carrying handle forms part of the packaging system. In practice, the transport of several of the packaging containers described above proves to be cumbersome for the consumer. In the prior art, there are already outer packaging that summarize a variety of packaging units. In the field of liquid foods, the so-called six-pack is known. Here encloses an outer packaging made of cardboard, in rare cases made of plastic six in two groups of three next to each other arranged bottles. Depending on the embodiment, a more convenient transport is possible, sometimes this outer packaging serves only to ensure a minimum purchase quantity by the consumer. The disadvantages of such outer packaging are the incurrence of further waste material. The cardboard used for this or the plastic material can be supplied to the general recyclable material for this category at best. Furthermore, a tearing of the outer packaging is not always possible without problems. This problem is solved for the embodiments described above by the carrying handle according to the invention. This flat part consists of a rectangular lower part, which is inserted between the arranged in a row of two packaging container, and an upper part, which protrudes as an extension of the rectangular lower part on top of the two row of Verpackungsbe- containers. This top may also have the shape of a rectangle, the dimensions need not correspond to those of the rectangular base, or it may be trapezoidal. In the trapezoidal shape, the shorter parallel side is preferably at the top of the top. In the upper part of a recess is mounted, which forms an engagement portion, which allows by the insertion of fingers, the transport of the packaging system.

Suitable materials are hard plastics, hardboard, solid board, metal, Metal alloys, wood, composites, glass fiber, rattan or combinations thereof. The upper part and the rectangular lower part need not be made of the same material. However, a uniform material is preferred. Embodiments of hard plastic are particularly preferred.

On the outer sides of the rectangular lower part, the carrying handle according to the invention has, at the level of each packaging container, a fastening region which enables a stable connection of the carrying handle to the packaging containers. At the same time, however, this attachment must allow by little effort a detachment of the individual packaging container of the carrying handle and thus of the whole support unit.

This attachment region may consist of a plurality of adhesive dots. These adhesive dots give the necessary stability, but are easily separable. In a preferred embodiment, each packaging container is connected to the carrying handle via two attachment areas mounted one above the other. Each of these attachment areas has a plurality of adhesive spots which are arranged in a circular or ellipsoidal manner. By simply tearing off the carrying handle, the separation takes place at these adhesive points. Alternatively, a thin continuous glue line or multiple thin linear circular or ellipsoid adhesive sections may be used. In these embodiments, a full-surface bonding is not conducive and therefore not preferred. After separation of all packaging containers, the carrying handle can either be used again after a cleaning step in order to remove the remaining adhesives, directly in a separate recycling process, or be supplied to a material recycling appropriate to its material.

In a further preferred embodiment is a full-surface bonding of two superimposed circular or oval mounting areas between carrying handle and packaging container. At the edge of such a mounting area of the carrying handle is perforated. The distance of the perforation holes is designed such that a simple tearing on the carrying handle leads to a moderate break on this perforation line. The glued Areas of the carrying handle thus remain on the packaging container, while in the carrying handle in these areas a sollmäßig recess is formed. After separation of all packaging containers, the carrying handle can be supplied to a material recycling appropriate to its material, but is not suitable for direct recycling.

In a preferred embodiment of the carrying handle is made of two mirror-image halves, which are connected to each other via a fold line or a hinge connection. Such a mode of production allows the adhesive needed for the application to be applied only on one side of the carrying handle. The two mirror-image halves are brought to lie in the next step by folding one half of the fold line or the articulation so congruent to each other that the two coated with adhesive sides come to lie outside. In further embodiments, the two halves may be additionally connected to one another by at least one further adhesive connection, a plug connection, a button connection, a folding mechanism, a stapling device or combinations thereof for the purpose of stabilization. Preference is given to a folding mechanism in which, in the engagement region of one or both mirror-image halves, the punch-out region of the cut-out region takes place only on three sides, while the side coming up during the carrying process is not punched out, but has a fold line or a hinge connection. Such an arrangement makes it possible that when superimposing the two mirror-image halves remaining in the engagement area material part of a half of the carrying handle can be bent by engagement with the opposite side of the carrying handle and folded up there. If there is also such a remaining material part on the opposite side, it will be flipped upwards. As a result, the two mirror-image halves are stabilized side by side. In an alternative embodiment, the first material part remaining in the engagement region comprises only one half of the recess area, wherein the parting line is perpendicular to the longitudinal axis of the recess area. In the mirror-image half of the carrying handle, there is a complementary second piece of material in the area of engagement, not from the first one Material part is covered. This arrangement allows each of the first and second pieces of material to be guided and bent upwardly by the engagement of the mirror-image half to stabilize the handle. In alternative embodiments, Velcro closures are used. The attachment portions described in the previous embodiments are each formed by a hook tape or an eyelet tape of a hook and loop fastener. Preference is given here square or rectangular attachment areas. It does not matter whether the hook tape or the eyelet tape is attached to the carrying handle or the packaging container. An advantage of this embodiment is that the carrying handle can be reused directly. If the outer jacket of the packaging container is also made of plastic, the outer jacket and the part of the hook and loop fastener located on it can be disposed of together or optionally supplied to a recycling system.

In a further embodiment, the connection between the carrying handle and the packaging container takes place via magnetic forces. In this case, a permanent magnet is embedded in the mounting region of the carrying handle, while a magnetizable substance is located in the outer jacket of the packaging container in the corresponding attachment region. A slight pulling or moving the packaging container solves this from the carrying handle. An advantage of this embodiment, in turn, is that the carrying handle can be reused directly.

Another preferred group of embodiments of the packaging system according to the invention relates to the nature of the outer jacket. In these embodiments, the outer shell of at least two hard-shaped mirror-image molds or hard shells which are connected to one another via at least one hinge joint, while on the opposite side in mirror image joining the two hard shells on at least one shutter mechanism, the two hard shells releasably connected together be and thus form a hollow body. The least two hard shells each have a flat bottom piece, which together form the bottom of the outer shell and thus of the packaging container according to the invention. The area of these floor pieces must be in proportion to the vertical dimensions of the hard shells in a relationship that allows stable storage in a vertical position in both the filled and deflated condition of the inner flexible bag. This outer jacket of this nature must also have a recess into which the outlet part and the associated inner flexible bag are inserted. This outlet part is located either in the upper or in the lower third of the respective hard shell. If the recess for receiving the Auslassteiles located at the top of the upright packaging container, the recess may be mounted centrally, ie when using two mirror-image hard shells in the middle of the centrally located edge each have a semicircular recess with the same radius, which complement when merging the two half-shells to a circular recess. When using more than two hard shells or two hard shells of different sizes, the recess changes accordingly. However, embodiments with two mirror-image hardshells are particularly preferred. Alternatively, the recess may also be mounted only on one side of the surface. In this case, therefore, the hard shells would be asymmetrical in the area of their top. Alternatively, there are also embodiments of the invention in which the outlet part is located at the bottom of the packaging container. These embodiments are exactly mirror images of those previously described. Furthermore, in some embodiments, the outlet part is mounted in the lower third of the packaging container. Preference is given to variants with an outlet tap.

Thus, the invention relates to a packaging container for pourable liquids, powders and granules comprising an inner flexible bag with an outlet opening, an outlet part and an outer jacket, wherein the inner flexible bag is fixedly connected to the outlet part, the outer jacket the inner flexible bag encloses the inner flexible bag is separably connected via the inserted into a recess outlet part with the outer shell, the outer shell consists of at least two hinged hardshells, which are hinged together via at least one hinge connection and have at least one releasable locking mechanism. Preferred is a packaging container for pourable liquids, powders and granules, comprising an inner flexible bag with an outlet opening, an outer jacket and an outlet part, wherein the inner flexible bag is not connected to the outer shell, the outer shell consists of two mirror-image hardshells which are connected to each other via at least one articulated connection on one side of the hard shells and via at least one releasable locking mechanism on the opposite side of the hard shells or via at least two releasable locking mechanisms, the outer sheath completely enclosing the inner flexible bag except for the area of the outlet part, the inner flexible bag is fixedly connected to the outlet part, and the inner flexible bag is reversibly attached to the lower end of the outer jacket.

In further embodiments, it may be according to the invention also two or more recesses for inserting the Auslassteiles in the hard shells. These can be attached in any combination on the respective pages. However, it is preferred that the two or more recesses be on the same side. For example, in each case a recess can be embedded in the top of a hard shell. It is preferred to install in each recess exactly one outlet part with an associated inner flexible bag. However, it is conceivable from embodiments in which there are two or more outlet parts on an inner flexible bag, which are then inserted into the two or more recesses. Likewise, it is conceivable that one or more recesses are not used. The outlet part can be produced as in the previously described embodiments, preferably with an outer jacket made of cardboard. Again, embodiments with a valve that allows only the exit of the contents of the packaging container, but no air, gas or liquid in opposite direction in the inner bag enter, preferably.

The materials for the hard shells must have sufficient stability and wear resistance.

Suitable materials include plastics, composites, metal, metal alloys, hardboard, wood, glass, stone, ceramics, porcelain, ceramides, pressed board, cellulose, leather, hardened raff, rattan, natural fabrics, fabrics and combinations thereof. In a particularly preferred embodiment, the hard shells are made over the entire surface of plastic or plastic. Suitable plastics are polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyesters, polystyrene, polyamides, polycarbonates and other polymers which preferably do not contain halogens.

Basically, there are no size specifications for the hard shells according to the invention. However, preferred are sizes that can be used for household use or commercial delivery quantities. Optionally, product information, advertising, or a two- or three-dimensional design may be affixed to the exterior of the hardshell.

In a preferred embodiment, one or two of the side surfaces of the hard shells have a handle which is suitable for facilitating a removal operation by engagement of fingers. In industrial applications, a handle or a handle edge can be used, which can serve as a starting point for a gripping arm.

The articulation between the hard shells may be fixed or separable. In the latter case, so the hardshells can be separated, or optionally replaced or recombined with different design.

As joint components all common possibilities come into consideration. The joint components can be made of the above materials as the flat parts be. Preferably, flat parts and joint components made of the same material. The joint components can only limited by the thickness of the flat parts to be rotated approximately 360 °, or contain locking devices that allow rotation to approximately 180 ° or 90 °.

The opposite releasable locking mechanism may be a push button, a flap, a clip, a slide-in tab, a plug connection, a click connection, a hook connection, a snap lock, a screw connection, an adhesive connection or a seam.

This locking mechanism can be unidirectional or parallel (bidirectional).

The invention also includes a closure mechanism in which at least one articulated connection consists of at least one return spring. In this case, no such device is attached to the edges of the hard shells in which there is a connection in the previously described embodiments. For each return spring, the spring constant is chosen such that on the one hand only a small amount of force to open the hardshells is necessary, on the other hand, the hard shells after loading or removal of the inner flexible bag again firmly closed and thus ensures safe transport and safe use of the packaging container is.

In some embodiments, said hinge connection may also be replaced by a releasable closure type as previously described. In this case, the hard shells can be completely separated. For these embodiments, it is preferred that the releasable closures between the hard shells are the same. In further preferred embodiments, hook-and-loop fasteners or magnetic connections are used as described above for the carrying handle.

In other variants, the articulation described above is in each flat-manufactured upper part or lower part of the packaging container. In this case, the side parts are fastened to each other via two of the releasable closure mechanisms as described above. Again, it is preferred that the releasable locking mechanisms are the same. The recess for receiving the Auslassteiles in the hard shell is then preferably located on the side opposite the hinge connection or side.

Optionally, a seal made of plastic or paper can be attached via the at least one releasable locking mechanism. In this way it can be ensured that no replacement or removal of the inner flexible bag has been made between filling or loading by the producer or by a middleman. Thus, such a seal can be used as an original certificate. The hard-shell packaging containers may be egg-shaped, eggplant-shaped, pear-shaped, kidney-shaped, bell-shaped, spherical, cylindrical, conical, conic, cuboid, pyramidal, or combinations thereof. Optionally, any shapes can be made on recesses on the side panels. This material can be saved in the hard shells and the view of the interior of the hollow body with the inner flexible bag is possible. Furthermore, according to the invention, the surface of the side parts can also be varied, for example by a circumferential wave form. This can be done over the entire surface or only on a specific section of the side parts. An advantage arises from the better accessibility in a household use.

The side parts of the hard shells in these embodiments may, if they are not full-surface, consist of a frame having vertical, horizontal or diagonal struts each in a number of 0-10, preferably 1-5, more preferably 2-3 has a grid structure. These struts can not only be linear, but also any curves, circles, Waves, zigzag shapes and the like assume.

The outlet part with the inner flexible bag attached to it must be inserted into the space provided in the hard shell. Here, all the usual clamping and locking mechanisms are conceivable. If the packaging container has only one recess for receiving the outlet part, i. Each hard shell has a mounted at the edge of the upper half-circular recess, the outlet part is inserted into one of the two semicircular recesses. Each edge of the Auslassteiles comes ring-shaped directly above and lie directly under the top. When closing the two hard shells, the inner flexible bag is clamped between the two hard shells. The two annular edges above and below the tops of the hard shells prevent the inner flexible bag from being unintentionally pulled out of or falling out of the outer sheath, or that the outlet portion from falling into the interior of the packaging container, particularly at an advanced emptying condition.

If there are two or more recesses for receiving the outlet part on the hard shells of the packaging container, then a corresponding number of keyhole-shaped openings are located on the contact edges of the upper parts of the hard shells. Here, the outlet part comes into the central circular part of the recess, wherein the narrowest point of the tapered access part of the recess, which lies at the edge of the central circular portion of the recess, acts as a clamping mechanism. By a small amount of force, the outlet part can be attached in this way or removed later.

According to the invention, the inner flexible bag must be fastened to one or both hard shells on the side opposite the outlet part, in order to allow optimal emptying of the contents of the bag. This attachment is preferably an easy to perform and intuitively understandable process.

In a preferred embodiment, one or both flat shells have a hooking device for the adjacent side of the inner flexible bag. in this connection For example, the hook on the flat part and the eyelet on the inner flexible bag, or the eyelet on the flat part and the hook on the inner flexible bag can be located. In a further preferred embodiment, the underside of the inner flexible bag is such that it comprises a press seam or a weld. With this seam, the inner flexible bag is inserted into a guide rail located on the adjacent side of the flat shells or flat shells. The guide rail is preferably mounted on the hard shells in such a way that when the hard shells are brought together, both halves of the guide rail form a continuum. This guide rail holds the inner flexible bag in place and prevents the inner flexible bag from inadvertently slipping out of the track during transport and / or use. This guide rail may be a simple clamping device or include an additional, actively operated clamping mechanism such as a thumbscrew or a clamp switch. In a particularly preferred embodiment, the inner flexible bag below the said seam has sufficient material which projects somewhat from the seam in the form of two strips. With this area it is introduced from the side in such a rail, wherein the seam comes to lie at a bottleneck in the profile of the guide rail. This prevents unintentional slipping out.

In a further embodiment, the inner flexible bag is attached via a Velcro on the side facing away from the outlet part on the adjacent surface of one or both hard shells. It does not matter if the hook tape is attached to the inner flexible bag and the eyelet band is attached to the hard shell or vice versa. In a further preferred embodiment, a permanent magnet is located in the lower parts of the hard shells, while a magnetizable material is located in the adjacent side of the inner flexible bag. The magnetic forces created by contact make it possible for the inner flexible Keep bags in the desired stable position within the folded outer shell. At the same time, however, these magnetic forces can be overcome by a slight force of a user, another person or a device, which allows the easy detachment of the inner flexible bag from the said hard shells.

Even with the use of hard shells, in other embodiments, an inner flexible bag can be used whose volume in the filled state is significantly smaller than the outer sheath. Optionally, the inner flexible bag is attached via a special bracket on the outer jacket here as well. According to the invention, a correspondingly large hooking device can be used for this purpose.

Advantages in the use of hard shells as the outer jacket of the packaging container according to the invention is the robustness and the easy attachment and removal of the inner flexible bag.

The use of hard shells is also particularly suitable for a recycling system which forms part of the packaging system according to the invention. After removal of the inner flexible bag, the hard shells are already separated on the releasable locking mechanism. While the inner flexible bag can be fed to a suitable recyclable material, the hardshells can be reused immediately. As a rule, no cleaning step is necessary. Otherwise, the hard shells can also be recycled. For this purpose, collection points at a dealer and / or producer of the inner flexible bags of a particular content are available. There, the hard shells can be equipped on site with a new inner flexible bag, or can be spent collected at such a place. If the hard shells have rounded side parts, these can be stacked particularly easily and space-saving. Connected via the joint, at least two equally fast growing piles form side by side. Should the hard shells also be separated at the hinge connection Of course, they can also be stacked on one or more piles.

This is particularly suitable for collection points in hypermarkets and for industrial companies, where many hardshells incurred. Stacked into each other, these can be easily transported to their destination.

These embodiments with the use of outer shell hard shells also refer to a separate inner bag and outer jacket disposal method comprising the steps of: a) providing a packaging container according to any one of the preceding claims;

b) unfolding the hard shells of the outer shell;

c) pulling the Auslassteiles and attached to him inner flexible bag from the respective hard shell, and

b) inserting the outlet part into the outlet opening of the inner flexible bag;

c) inserting the composite of outlet part and inner flexible bag in the outer shell, wherein the outlet part comes to lie in the region of the recess of said hard shells;

d) attaching the side of the inner flexible bag facing away from the outlet part to the side of the outer jacket opposite the recess of the outer jacket; and

e) sealing the hard shells. Optionally, the following step may follow the procedure described above:

f) If the inner flexible bag was not filled or partially filled in step a), completely or partially fill the packaging container over the outlet part.

In a further preferred embodiment, the outer jacket is made of a plurality of flat parts. These flat parts can be formed by suitable folding into a suitable outer jacket for the packaging container according to the invention. This outer sheath encloses the inner flexible bag largely completely in the folded state. At least one of these flat parts has a recess which is suitable for securing the outlet part and the inner flexible bag fastened to it to it or alternatively for inserting it in the recess. The adjacent in the unfolded state flat parts are movable against each other either by a fold or by at least one hinge member.

Suitable plastics are polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyesters, polystyrene, polyamides, polycarbonates and other polymers which preferably do not contain halogens.

Likewise, natural polymers such as starch, cellulose and their derivatives are suitable for this purpose.

In a further embodiment, the flat parts in their longitudinal axis or in its transverse axis on a Sollfaltlinie or consist of two at least one additional, as described below articulated connection. This additional subdivision can serve the better stackability or easier transport of the unfolded outer jacket. The Sollfaltlinie or articulation are preferably horizontal in the amount of half the width or length of the flat parts. According to the invention, however, the flat parts may also comprise two or more desired fold lines. The person skilled in the art can readily attach these with his or her expertise or modify existing embodiments accordingly, without deviating from the idea of the present invention.

According to the invention contains at least the flat part, which is provided for the upper cover of the packaging container, a recess for fixing the Auslassteiles and the associated with him inner flexible bag. This recess may be circular or have access to an accessible on the loading side of the top cover of the packaging container, whereby an assembly can be made via this side opening. Such a recess is preferred in the form of a keyhole. Here, the outlet part comes into the central circular part of the recess, wherein the narrowest point of the tapered access part of the recess, which lies at the edge of the central circular portion of the recess, acts as a clamping mechanism. By a small amount of force, the outlet part can be attached in this way or removed later. However, the outlet part can also be attached in other embodiments via a snap closure or a lever. Alternatively, an adhesive connection or a hook and loop fastener according to the invention.

As joint components all common possibilities come into consideration. The joint components can be made of the above-mentioned materials as the flat parts. Preferably, flat parts and joint components made of the same material. The joint components can only limited by the thickness of the flat parts to be rotated approximately 360 °, or contain locking devices that allow rotation to approximately 180 ° or 90 °.

On the side surfaces of the flat parts, which do not come to lie next to each other in the unfolded state, but in the folded state, there are closure devices that the folded and loaded with an inner flexible bag Stabilize packaging containers in their shape. For this purpose, all common closure devices are conceivable. Preference is given to connectors, Einhakvorrichtungen, snap locks and magnetic locks, Velcro fasteners and any combinations thereof. Particularly preferred are connectors. The attachment of the respective complementary parts of a closure device on the side surfaces of the flat parts is conceivable in all combinations according to the invention.

The inner flexible bag and the outlet part have the same characteristics and variation possibilities in these embodiments as in the previously described embodiments.

In a preferred embodiment, the flat part opposite the outlet part has a hooking device for the adjacent side of the inner flexible bag. Here, the hook on the flat part and the eyelet on the inner flexible bag, or the eyelet on the flat part and the hook on the inner flexible bag can be located.

In a further preferred embodiment, the underside of the inner flexible bag is such that it comprises a press seam or a weld. With this seam, the inner flexible bag is inserted into a guide rail which is located on the inside of the lower cover provided as the flat part of the outer shell. This guide rail holds the inner flexible bag in place and prevents the inner flexible bag from inadvertently slipping out of the track during transport and / or use. This guide rail may be a simple clamping device or include an additional, actively operated clamping mechanism such as a thumbscrew or a clamp switch. In a particularly preferred embodiment, the inner flexible bag below the said seam has sufficient material which projects somewhat from the seam in the form of two strips. With this area it is introduced from the side in such a rail, wherein the seam comes to lie at a bottleneck in the profile of the guide rail. This will cause an accidental slipping out prevented.

In a further preferred embodiment, a permanent magnet is located in this flat part, while a magnetizable material is located in the adjacent side of the inner flexible bag. The magnetic forces generated by contacting enable the inner flexible bag to be maintained in the desired stable position within the folded outer shell. At the same time, however, these magnetic forces can be overcome by a slight force of a user, another person or a device, which allows the easy detachment of the inner flexible bag from said flat part.

Even with the use of foldable flat parts, an inner flexible bag can be used in other embodiments, the volume of which is significantly smaller in the filled state than the outer shell. Optionally, the inner flexible bag is attached via a special bracket on the outer jacket here as well. According to the invention, a correspondingly large hooking device can also be used here. One application of these embodiments to an outer sheath of foldable panels is use in an integrated recycling system. Here, the contents, such as a drinkable liquid such as milk or orange juice, sealed in the inner flexible bag provided. This inner flexible bag is inserted into the outer shell such that the said flats are folded around the inner flexible bag. The inner flexible bag is in this case suspended or fastened via the outflow part to the recess of the flat part of the outer jacket which is provided as the upper cover. At the bottom, the inner flexible bag is attached to the inside of the lower cover provided as the flat part of the outer shell. The closure devices of the outer shell are closed, whereby the packaging container is stabilized in shape and can be used by a user. If no more contents can be removed from the packaging container or should be, the outer shell and the inner flexible bags are separated by draining the steps described for assembly. The outer jacket is reused in the same form. Optionally, the outer jacket is cleaned as needed, after each use or at fixed intervals. The inner flexible bag with the outlet part are fed to a suitable recycling.

An advantage of using mismatched sizes of inner flexible pouch and outer shell is that only one size of hard shell or foldable flat is needed to bring different volumes of an inner flexible pouch onto the market. The recycling system for the outer jacket is accordingly simplified and possibly easier standardized.

The assembly and disassembly of the packaging container according to the invention may be carried out by the end user, the producer of the filled inner flexible bags, an intermediary or by specialized personnel or combinations thereof.

Both in the use of hard shells as well as flat parts as an outer jacket, this recycling system can be combined with a deposit system according to the invention, the end user pays a deposit on acquisition of an assembled and filled packaging container, which he receives back as soon as he unfolded the outer jacket and / or returns the evacuated inner flexible bag to a designated location. Payment and refund of the deposit fee can be made via cash, a credit card, a specially created transfer card, advance deposit chips or billing.

A tubular bag is made of polyester and the other made of polyurethane. They each have an edge length of 9.5 cm X 5.5 cm X 19.2 cm and a filling volume of 1 L. On the top center of each hard shell and about 1, 3 cm from the shorter edge away is a spout optional with Valve.

The outer shell consists of cylindrical glass hard shells and has a height of 19.5 cm. The two hard shells of the inner flexible shell each have a guide rail, in each of which the pressure seam of the inner flexible bag are jammed. The tops of the two hard shells each have at their contact line a keyhole-shaped recess into which the respective outlet part of the inner flexible bag is inserted and clamped. The two hard shells are fastened to one another via a Velcro fastener, one hard shell having the hook band and the other hard shell having the eyelet band.

Example 4:

A packaging container for 1 L of orange juice is described, which consists of a tubular bag and an outer collapsible jacket, which is reused in the deposit system.

The tubular bag is made of polypropylene and is welded so that it already has approximately the shape of a cuboid with the edge lengths 9.5 cm X 5.5 cm X 19.5 cm and has a capacity of 1 L. On the top center and Approx. 2.0 cm from the shorter edge, the spout is optionally equipped with a valve. The outer collapsible shell is made of hardboard and has the shape as shown in FIG. The edges of the side, bottom and top surface are designed so that they are movable into one another and, when fully assembled, result in a solid and stable parallelepiped with the edge lengths 10 cm X 6 cm X 20 cm. If two parts of the outer collapsible jacket are inserted into one another, they can be moved along the longitudinal axis of the connector. The movement patterns and the manner of assembly are clearly shown in FIG. 9, where hinges are shown in FIG. 9 and the embodiment described here uses moveable interlocking perforations, wherein a spherical or hemispherical configuration can be inserted into a corresponding recess of the counterpart and vice versa, so that ultimately results in a hinge function. The upper side of the outer collapsible jacket has a recess into which the spout opening provided with a collar of the tubular bag can be suspended, clamped or pushed in as shown in FIG. The tubular bag is held firmly in the outer collapsible jacket by this recess.

So that the tubular bag can be completely emptied is also on the inside of the bottom surface of a simple clamping device, wherein the lower weld of the tubular bag can be clamped so that the tubular bag does not coincide when emptying and can be completely empty.

After complete emptying of the tubular bag, the outer collapsible coat can be opened again and the tubular bag removed and disposed of. The outer collapsible jacket can be reused for a new filled tubular bag or preferably returned in the deposit system.

Another advantage with respect to the outer collapsible shell is that it can be fully unfolded for return transport and transported as a flat folding pattern, which saves space and is very environmentally friendly due to the reuse in the deposit system and contributes to waste prevention, because only the tubular bag must be disposed of.
