Description

Pack for flowable products

The invention relates to a packing for flowable,

especially liquid and viscous, products with a

flexible inner bag for receiving a product, wherein the inner bag is provided with a closure having a spout, and with an outer package, which at least partially surrounds the inner bag and supports the inner bag.

With an outer packaging in the context of the present invention, a relatively stiff compared to the flexible inner bag material or element is meant, which is suitable to keep the inner bag in an upright position permanently. Such outer packaging is usually of one

Cardboard casing, which usually has a cuboid shape formed. Basically, even a relatively stiffer

Plastic used.

A typical package of the type previously described, with a flexible inner bag and a relatively rigid carton as the overwrap, is the so-called "bag-in-box" package, which has been known as a liquid container since the 1950's. The inner bag is made of a flexible film composite material that is mechanically supported by a corrugated cardboard or the like. The inner bag is usually with a pressureless

Liquid, such as a beverage, filled and closed at one end via a tap having a spout. The so filled and closed inner bag is then inserted into the outer packaging. The the Outer packaging forming cardboard is then completely closed.

The problem with the preceding pack is the relatively complicated operation for the consumer. So must the

First, in the outer packaging, provide an opening by placing a usually pre-cut window in the container

Press in cardboard material. Then the consumer has to grab the tap inside the box and lead it out through the previously made opening. Afterwards the packing must be aligned so that the liquid can flow out automatically when opening the tap. Only then can the consumer open the tap and remove the liquid. The tap is always mounted at the bottom to drain the liquid with the help of the static pressure and the inside collapsing bag,

what in the use of a container of several liters,

For example, 20 liters, is cumbersome. Such a pack has so far in private

Consumer has not yet enforced, but is mainly used in the catering industry. This is certainly due firstly to the fact that the end user is accustomed to consuming liquids from plastic or glass bottles in which he has only one

Screw cap, bottle cap or cork must solve and then pour the liquid immediately by tilting the bottle. In comparison, the use of a bag-in-box system is relatively complex. On the other hand, the bag-in-box system has the disadvantage that a tap, albeit to a lesser extent, accumulates drops, which is undesirable

Pollution in the consumer household has the consequence. Also is the liquid so that it can drain with open tap, the tap always under pressure, so that in the event that the tap unintentionally not completely

has been closed, liquid from the pack

which can reduce the risk of contamination of the

Environment further increased (risk of leakage).

In gastronomy, the above disadvantages are less relevant, since they are often large packs of several liters, usually up to 20 liters, the

hold accordingly and do not need to be changed so often. In gastronomy, these packs are usually in the taproom or in the kitchen, which areas are cleaned daily anyway and are also easier to keep clean due to special functional surfaces than in the case of a private household.

Against this background, therefore, exists on the part of

Beverage industry's needs, beverage wraps and

To develop the like, on the one hand, relatively easy to use and are therefore more easily accepted by the end user. On the other hand, the trend is too

environmentally friendly and resource-saving materials. Finally, it is also desirable if the emptied pack occupies the lowest possible volume, which is the

Disposal and easy separation of plastic and cardboard facilitates.

From the prior art and plastic bags are known as packages for liquids, the two

opposite side walls made of a relatively stiff

Plastic and two orthogonal side walls made of one have relatively flexible plastic and are provided on its upper side with a cap having a spout. These packs are easy to use, on the one hand, and recyclable, on the other

Plastic, environmentally friendly and resources

gently. Also, these packages can be folded in the emptied state to a relatively small volume.

Due to the use of different stiff plastics but the production of the packages is relatively expensive. Also, compared to carton packs, the packs have a relatively unstable state and therefore can not be made arbitrarily large, especially as far as the height is concerned.

It is an object of the present invention to further develop a package of the type mentioned above, which has a flexible inner bag and an outer packaging, in such a way that the convenience in the application by the consumer is improved.

The previously derived and indicated task becomes

According to the invention, in a pack of the type mentioned at the outset, the overpack has an opening, through which the spout is guided to the outside, the spout being connected to the outer packaging, in particular detachably,

connected is.

By the outer packaging from the outset (manufacturer) has an opening through which the spout is already led from the outset (manufacturer side) to the outside, the consumer to the pack to remove the product, such as a drink or the like, not only laborious even provide an opening in the outer packaging and then reach through this opening the spout and lead to the outside. In addition, since the spout is connected to the outer packaging, the spout is fixed to the outer packaging and can not unintentionally get inside the outer packaging, where this would then laboriously be gripped and brought out again. By fixing the

Spout on the outer packaging can be used as a closure in a simple way a cap, especially a screw cap, use. By a

twist-proof connection between spout and outer packaging, such a screw can be easily unscrewed by the consumer with one hand, even if the screw is relatively tight because the spout and the inner bag can not rotate relative to the outer packaging, if a rotational force on the screw cap or the closure cap is exercised.

For the consumer, such a package is as easy to use as a conventional bottle with a screw cap.

The comfort for the consumer, in particular the private end user, is thus significantly higher than the known bag-in-box system. This is even more so, as such a pack as well as conventional bottles with upward

pointing spout, which minimizes the risk of leakage even if the spout is not properly closed. Also, during the pouring at the spout accumulating drops do not lead to pollution of the environment, since after using the pack, this again automatically so is aligned so that the Äusgießeröffnung facing up and thus drop back drops. In contrast, in the known bag-in-box system, the spout with the

Tap from an opening in a side wall near the

Take out package bottom, which arrangement is not

Prevents drops from the tap into the environment.

In addition to a simple application is another advantage of the possibility of using environmentally friendly and resource-saving materials, such as recycled or

Recyclable plastic for the flexible inner bag and recycled / recyclable carton

(Cellulose fiber material) for the outer packaging. Also, by the stable outer packaging, such as a cardboard, the inner bag, since it is optimally supported and protected, are made of a relatively thin film, which the packaging costs and weight benefits. Since inner bag and outer packaging are not connected to the connection, in particular hooking and / or welding of the spout to the edges of the opening in the outer packaging, finally, if the

Connection between spout and outer packaging is carried out detachable, the outer packaging readily separated from the spout having inner bag, which also separate disposal of different

Materials, such as cardboard on the one hand and plastic on the other hand, is readily possible. By a releasable connection is meant such a connection, which from the

Consumers readily by hand, that is without much effort and without the use of tools, solvable. The connection between spout and outer packaging is therefore just just so strong that at a

Proper loosening or unscrewing (or putting on or screwing on) the cap and a

Proper use of the package in the event that the product is to be removed, the connection withstand, but as soon as a greater relative force between spout and outer packaging is used, as is necessary for the intended use, the outer packaging immediately dissolves the spout with the bag. The latter can be favored, for example, by the lid of the outer packaging is unfolded or released from the remaining part of the outer packaging. In the following, further embodiments and

corresponding advantages of the package according to the invention

described.

According to one embodiment of the package according to the invention, the outer packaging has a bottom, a plurality of side walls, preferably four side walls, and a lid, wherein the opening is provided in the lid and the spout is connected to the lid, in particular detachably. Such outer packaging is particularly stable, visually appealing and easy to use by the user. Also, such a package is optimal, even in large quantities, storable.

According to a further embodiment of the packing according to the invention it is provided that the spout has a radially outwardly projecting flange and a radially outwardly projecting collar, wherein the flange and the collar are spaced apart in the axial direction, wherein the distance is in particular less than 4 mm, preferably less than 2 mm, particularly preferably less than 1.5 mm. The flange and / or the collar may be of a circumferential ring or of several in the circumferential direction

arranged tabs are formed. The flange, which may be arranged at the bottom, directed to the inner bag end of the spout, serves to fasten the

Inner bag at the spout. Preferably, the spout is guided from the inside through an opening in the bag to the outside, wherein the flange comes to rest on the inside of the bag. The film of the inner bag and the flange then become

connected to each other inextricably, for example by

Heat sealing with, in particular, permanently heated sealing jaws or ultrasonic welding. The collar, which is spaced in the direction of pointing away from the inner bag end of the spout from the flange, serves as an attachment for the outer packaging, in particular the lid. It is preferably provided that the spout is guided through an opening in the inner bag to the outside, wherein a portion of the outer packaging,

in particular the lid, and a portion of the inner bag between the flange and the collar are arranged, in particular jammed, are.

In this case, the portion of the outer packaging, in particular of the lid, have incisions, which are used to open the

Repackaging point and in particular radially

Center of the opening are directed. The length of the

Notches corresponds at least to the radial extent of the collar, so that the lid or the outer packaging can be simply slipped over the collar, especially in the manufacture of the package, when the opening part of the outer packaging, such as the lid, with the Spout and the collar is connected. Equally, however, this also applies to the case that in an example emptied pack of the opening portion of the

Outer packaging or the lid is opened or removed from the spout to separate the inner bag from the outer packaging.

As already indicated above, according to one embodiment, the collar-facing side of the flange with the

Inner bag connected liquid-tight. The flange is preferably located on the inside of the inner surface of the inner bag. The flange-facing side of the collar is, as also already indicated, preferably connected to the outer packaging, in particular the lid, so that, from the inside out, an exemplary layer structure results, starting with the flange, followed by a

Section of the inner bag (that is, the film of the

Inner bag), followed again by a section of the

Overpack or the lid and finally ending with the collar.

In order to achieve a permanent and yet easily detachable connection between spout and outer packaging, it can be provided that the connection between the collar and outer packaging, in particular cover, is a punctiform connection, which is preferably formed by sealing points, particularly preferably ultrasonic welding points , By providing sealing points or ultrasonic welding points can be dispensed with adhesive, since in the sealed area of the

Plastic of the collar and / or the surface or

Coating the overwrap locally heated and fused, creating a permanent and adhesive-free compound between collar and outer packaging arises. In particular, the outer packaging, at least in the region of the connection to the collar, is provided with a surface, in particular a coating, which is configured to form an adhesive bond with heated (ie liquefied) plastic after it has hardened. In principle, however, it is also conceivable to produce the connection between spout and outer packaging by means of glue, in particular hot glue. Thus, in particular in the case of a punctiform connection, this is a relatively small area to be connected, so that, in particular if the outer packaging is made adhesive-free, the package nevertheless

can be produced environmentally friendly and cost-effective. According to a further embodiment, the flange has a larger diameter than the collar, wherein the flange in a portion which is covered in the axial direction by the collar, has a greater thickness than in the remaining part. In this way, on the one hand, the insertion of the (cardboard) material of the outer packaging in the region between the flange and collar is facilitated because the outer part of the flange behaves flexibly and elastically. The inner part of the

Flange, which is covered by the collar in the axial direction, however, is stiffer and favors jamming of the material of the outer packaging between flange and collar.

According to another embodiment of the invention

According to the invention, it is possible (but not mandatory) to make at least the connection between spout and outer packaging adhesive-free, that is to say no glue, in particular hot glue, is used for the connection in the case. It is preferred additionally or alternatively also conceivable to join the outer packaging adhesive-free, for example by

Heat-sealing in particular with permanently heated sealing jaws or preferably by ultrasonic welding. Such

Adhesive-free packaging is special on the one hand

environmentally friendly, but also relatively

inexpensive in production. Also, a corresponding manufacturing device, since an adhesive is dispensable, be simpler structure.

The inner bag is connected according to still another embodiment of the package according to the invention only on the spout with the outer packaging and movable in the outer packaging. In other words, the inner bag is fixed only on the spout, but not on the outer packaging. In this way, when emptying the pack, so if for example a

Liquid flows out, the inner bag accordingly reduce its volume around the part of the drained product. In other words, the inner bag thus according to the pouring of the product according to (collapses), which has the advantage that during pouring no pressure equalization in the

Inside bag must be made, so no air during the

Pouring pouring from the outside. The latter results in non-compliant (collapsing) packs to a jerky outflow (pülschen) of the product, which

is successfully avoided according to the invention. In addition, by filling the bag with an air-free headspace, spilling over of the liquid at the first time may also occur

Opening the package can be reliably prevented, since then first air flows. The outer packaging, the spout and the inner bag can be made of different materials, as long as it is ensured that the inner bag is flexible and in the package during emptying as free to move as possible, that is collapse, and as long as the outer packaging of the flexible inner bag by a relative to Inner bag supports stiffer material and preferably also protects to all sides. From an environmental point of view, it is particularly recommendable if the outer packaging largely, preferably completely, consists of cardboard. The inner bag and / or the spout can largely, preferably completely, be made of plastic.

According to a further embodiment of the package according to the invention extends at least a portion of the lid, preferably the complete lid, obliquely to the bottom and / or at least one of the side walls of the pack. Such an oblique course facilitates the pouring of the

Product, since in this way, the spout, in particular when it is connected to a protruding perpendicular to the central axis of the spout collar with the surface of the lid, is correspondingly inclined. But it is also conceivable, regardless of the course of the lid, that the central axis of the spout obliquely to the ground and / or

at least one of the side walls runs. The angle between the oblique plane, in which said oblique lid portion or the lid extends, and the plane in which said bottom extends is, for example, 10 to 45 °, preferably 15 to 38 °, particularly preferably 20 to 25 °. The angle between the central axis of the spout and the plane through which the bottom passes is, for example, 45 to 80 °, preferably 52 to 75 °, particularly preferably 65 to 70 °. In principle, however, a rectangular instead of an oblique course is conceivable, that is, the lid is parallel and / or the central axis of the spout perpendicular to the ground.

In order to ensure a secure and stable connection between spout and outer packaging is provided according to a further embodiment of the package according to the invention that the wall of the spout in the region between the flange and collar has an enlarged cross-section. Such a

enlarged cross-section, which is so compared to the remaining cross-section of the wall of the spout is greater, increases the rigidity of the spout in the region with which it is attached to the outer packaging. Also, this is the

Area in which the outer packaging together with the

Inner bag attached to the spout, in particular jammed, can be, so that the clamping force does not wear off over time. According to yet another embodiment, it is provided that at least one of the side walls, preferably all

Side walls, at their end facing the lid have tabs that hook with provided on the lid tabs in the closed state of the lid, wherein

In particular, each tab of the side walls of a tab of the lid and / or each tab of the lid is associated with a tab of the side walls. In this way, the lid, which may be a hinged lid, can be easily connected to the side walls, which in turn benefits the stability of the entire package. Hooking tabs also have the advantage that on the one hand to the connection between the lid and side walls no Adhesive must be used and on the other hand in the manufacture of the pack an additional step of

Gluing or victory can be omitted. The hooking described above can be realized in a particularly simple manner, if according to another

Embodiment of the package according to the invention, the outer packaging consists of a one-piece blank. An integral blank also minimizes the number of points at which two adjacent sections of the outer package must be joined together, for example by ultrasonic welding.

A typical method for producing and / or filling a package, as explained above and later with reference to the figures, will be described below by way of example.

Such a method may include the following steps: a step of providing a film in one

Fill and seal machine,

a step of providing a plurality of

spouts,

a step of providing a plurality of

Material blanks with an opening,

a step of peeling the film into a

Production direction of movement,

a step of introducing openings into the at regular intervals in

Production direction of movement,

a step of inserting one of the spouts into each of the openings of the film,

a step of forming the film into a tube, a step of longitudinally sealing the film in

Production direction of movement,

a step of Querversiegeins the slide in

regular intervals in the production movement direction, - a step of separating individual film sections at regular intervals in

Production movement direction, whereby bags are separated,

a step of filling the bags with the product, - a step of sealing the bags in the head space, a step of erecting the individual ones

Material blanks and forming an outer packaging, a step of inserting one of the bags in each one of the outer packaging, wherein the respective spout is passed through the opening of the outer packaging to the outside, and

a step of generating one, in particular

detachable, connection between spout and

Outer packaging.

The foregoing steps are not limited to a particular order, but may be performed at least in part in almost any order.

For example, the steps can also be done in the

Order to be performed like this in the

preceding list of the invention

Procedural steps was used.

According to one embodiment of the method according to the invention, the spout with preassembled closure, in particular preassembled closure cap, which is a

Screw cap can act in the opening of the film used. But it is also possible to use the Äusgießer initially without closure and the closure only in a later process step, for example, after a

Fill up, sit up.

The openings of the film are according to another

Embodiment of the method according to the invention produced by a separate tool. Separately means that not the spout itself is used to create the openings, but this happens on the machine side.

Of course, but also the spout like that

be formed so that it is adapted to produce even the respective opening. The openings for inserting the spout are in particular punched.

As previously indicated, the individual can

Procedural steps in different order,

sometimes also simultaneously. Thus, it is preferred if the respective spout is inserted into the respective opening of the film before the step of forming the film into a tube. In principle, however, it is also conceivable to carry out the step of insertion after the shaping of the film.

It is also preferable to insert the respective spout prior to the longitudinal sealing and / or transverse sealing step, although this may be done afterwards. According to a further embodiment of the method according to the invention, the spout is fixed to the film, i.

insoluble, connected. Insoluble means that the connection can not be easily solved by the consumer, without applying an increased force. The

In particular, the spouts are connected to the film immediately after the step of inserting the spouts into the openings of the film. In principle, however, the connection could also be made later.

The compounds described above, ie the

Connecting the spout to the film and / or the longitudinal and / or transverse seals and / or the welding in the head space, carried out according to a further embodiment of the method by means of ultrasound. In principle, a heat-sealing with in particular permanently heated sealing jaws is conceivable. Preferably, however, should be dispensed with a separate adhesive for the preparation of the compounds, which is the

Simplifies procedures, accelerates them, makes them more environmentally friendly and makes it easier to recycle the individual packaging materials. In the step of transversely sealing the film, in each case a double seam is produced according to a further embodiment of the method according to the invention and the separation of individual film sections is effected by a separating cut between the seams of the double seam. In principle, however, it is also conceivable to provide a relatively wide transverse sealing with only one seam, in which case the severing cut is made through the seam such that a part of the seam is arranged on both sides of the separating cut. According to another embodiment of the invention

The method according to the invention provides that the step of forming the film into a tube via a Form shoulder takes place, which is in particular tubular, wherein preferably takes place via a arranged in the interior of the forming shoulder filling tube, the step of filling the bag. The filling is basically possible later, for example, after the insertion of the bag in the

Outer packaging. During filling, preferably 0.2 to 2 l of the product, preferably 0.25 to 1.5 l of the product, is introduced into the bag. According to another embodiment of the invention

Method is evacuated before the step of welding the bag in the head space and after the step of filling the bag with the product of the headspace, which is done automatically in particular. As a result, upon first opening the package and the bag, air first flows into the headspace of the bag, preventing any part of the product from inadvertently spilling over when the package is opened.

The filled and sealed bag is gripped according to a further embodiment of the spout and / or on the closure and is in particular to a transfer system

to hand over. The transfer system can be equipped with special rails, for example C rails, which engage in a groove provided on the spout.

According to yet another embodiment of the method according to the invention, the filled and closed bag, in particular from the transfer system, is inserted into the outer packaging. In principle, it is also conceivable that the unfilled bag is first inserted into the outer packaging and only then filled. According to yet another embodiment of the method according to the invention, the outer packaging after the onset of

Bag closed with a lid. In principle, but also outer packaging are conceivable that do not need to be closed because they consist for example of an annular strip, such as annular cardboard strips, which forms an inevitably open on both sides outer packaging, so that the bag can also be inserted from the side into the outer packaging.

Regardless of the shape of the outer packaging, it is according to a further embodiment of the invention

Provided method that the step of generating the, in particular releasable, connection between spout and outer packaging comprises generating a point-to-point connection. The connection, especially the punctual

Connection, as well as the other connections can be made by means of ultrasound. Basically, here is one too

Heat sealing with especially permanently heated sealing jaws conceivable. In any case, should be dispensed as possible with this connection as possible to an adhesive.

Furthermore, it is intended to briefly mention the material used in the method of the individual elements forming the package

To be received. Thus, the film and / or the spout is preferably made of plastic and / or the material blank preferably made of cardboard.

According to another embodiment of the invention

Procedure is performed this clocked. Several of the steps described above can also be done simultaneously be performed. But it is also conceivable that the

Procedure is carried out continuously.

There are now a lot of ways that

Fig. 5c) nor an alternative blank.

The pack 1 shown in FIGS. 1 to 5c serves for receiving and storing, for example, liquid products, especially drinks. The package 1 has on the inside a flexible inner bag 2 made of a thin Kunststofffolie for receiving the liquid and as an outer jacket a rigid Ümverpackung 5 on cardboard. The inner bag 2 is provided with a spout 4, which has a cap 3 which can be screwed on as a closure. The Ümverpackung 5 completely surrounds the inner bag 2 in the present case and serves on the one hand to support the inner bag 2 and on the other hand to protect it.

The Ümverpackung 5, which will be described in more detail below, has an opening 6, through which the spout 4 is guided to the outside. The spout 4 is detachable with the Ümverpackung 5, with their lid 5c

connected.

The Ümverpackung 5 has a bottom 5a, four side walls 5b and said cover 5c. The Ümverpackung 5 is, as the figures 5a) to 5c) show, made of a one-piece blank, which can be dispensed with glue for joining or holding together to form a parallelepiped Ummverpackung 5. The only ones too

connecting bodies would then be alone

Ultrasonic welding fixed together.

As shown in FIG. 2, the complete cover 5c extends obliquely to two of the side walls 5b, which also applies to the center axis M, which runs in the longitudinal direction X, due to the special way of fastening the spout 4 on the cover 5c.

The construction of the spout 4 and the way in which it is connected to the outer packaging 5 and the inner bag 2, becomes particularly clear with reference to FIGS. 3 and 4a). Thus, the spout 4 has a radially outwardly projecting flange 7 at its lower end and a longitudinally X thereof spaced radially outwardly projecting collar 8, wherein between flange 7 and collar 8, a section 5.1 of the outer package 5 and the lid 5c and a section 2.1 of the inner bag 2 is arranged. The distance between flange 7 and collar 8 is in the present case about 1.2 mm, so that the film of the inner bag 2 and the cardboard of the lid 5c are clamped therebetween.

To facilitate the assembly and disassembly of the lid 5c, in particular to facilitate the slipping over the collar 8, the cover 5c radially to the center of the opening 6 facing incisions 10, the length of which is greater than the radial extent of the collar 8.

The collar 8 facing side of the flange 7 is liquid-tightly connected to the inner bag 2, here by

Ultrasonic welding. The flange 7 facing side of the collar 8 is selectively connected to the lid 5c, here by several, in particular four, ultrasonic welding points 11 between the collar 8 and surface 12 of the lid 5c.

At least in the area of the ultrasonic welding connection, preferably in the area of the entire lid 5c, particularly preferably over the entire outer packaging 2, is a

Paint coating 12 is provided, which is formed so that the curing of the ultrasonic welding plastic of the collar 8 forms an adhesive connection with the paint coating or surface 12 of the outer package 5. The flange 7 has a larger in the present case

Diameter than the collar 8, wherein the flange 7 in a section 7.1, which is covered by the collar 8 in the axial direction X, has a greater thickness than in the remaining part 7.2.

As also shown in FIG. 4a), the wall 4a of the spout 4 is provided in the area between the flange 7 and the collar 8 with a slightly larger cross section than in the area above it, in which the cap 3 is arranged.

As described above, the outer package 5 is here

made adhesive-free. The same also applies to the connection between spout 4 and outer packaging 5. Thus, no hot glue or other glue is used in this embodiment.

An alternative spout 4 and an alternative

Fixing method shows Fig. 4b). In contrast to the exemplary embodiment in FIG. 4 a), here the collar 8 is omitted, wherein the outer package 5 and / or the inner bag 2 in this exemplary embodiment can be connected to the spout both with adhesive-free and with the use of adhesive. For a glue-free connection can

For example, an ultrasonic welding process can be performed.

It is, as Fig. 4b) shows, the opening 9 in the inner bag 2 is greater than the opening 6 in the outer package 5, so that not only the inner bag 2, but also the outer package 5 rests with its underside on a portion of the flange 7 and there can be connected to the flange 7. That's how it is Overpack 5 on the section 7.1 of the flange 7, while the inner bag 2 rests on the section 7.2 of the flange 7. The inner bag 2 is otherwise only connected via the spout 4 with the outer packaging 5 and movable in this, so that it can collapse. The only connection between

Inner bag 2 and outer package 5 is shown in Fig. 4. The inner bag 2 is therefore not fixed, with the exception of the previously described point on the spout 4, within the outer package 5.
