Description

Cardboard / plastic composite package with peelable lid and method and apparatus for its manufacture

The invention relates to a cardboard / plastic composite packing of a packing jacket provided with a longitudinal seam and with a folded and welded packing tray provided at one end of the packing jacket and to a method and a device for its production.

Cardboard / plastic composite packages have long been known and available in a variety of forms and shapes on the market. For example, they serve as beverage packaging or as packaging for other foods.

It is known to provide the packages with an opening aid to facilitate the consumer access to the product. For this purpose, an element is usually provided in the upper area of the cardboard / plastic composite package, which covers a casting opening provided in the cardboard / plastic composite packaging material. The pouring opening serves to pour out the product.

The element covering the pouring opening may be a peelable strip which releases the pouring opening upon removal.

Furthermore, it is known to attach a frame comprising the pouring opening to the cardboard / plastic composite package. The frame can be one Have lid that releases the pouring opening when opening. In turn, a strip may be provided between the lid and the pouring opening, which strip must be removed when the lid is first opened in order to access the product.

Alternatively, the lid may be integrally connected to the frame prior to the first opening. When first opened, the lid is then partially separated from the frame and releases the pouring opening.

Furthermore, the frame can also be provided with a pouring spout and thus serve as a pouring aid.

The frame may also have a threaded tube on which a screw cap can be screwed. In particular, the screw cap can be used to break open the first opening a perforation in the cardboard / plastic composite packaging material and thus the pouring opening is generated.

The above-mentioned elements for covering the pouring opening can in particular be designed so that they allow re-closing of the cardboard / plastic composite packing.

In the known cardboard / plastic composite packages, it is disadvantageous that they are only suitable for liquid content due to the usually very small pouring opening. In addition, the well-known cardboard / plastic composite packages with high-build pouring elements can not be stacked well and are therefore not optimally placed in the smallest space for transport and / or storage. The invention is therefore based on the object to provide a cardboard / plastic composite package, which is also suitable for non-liquid products and also can be stacked well.

This object is achieved with respect to the cardboard / plastic composite package according to the invention in that at the upper end of the packing jacket, a circumferential ridge is arranged and that on the web, a lid is removably attached.

The invention has thus recognized that by providing a web, a lid may be peelably secured to a carton / plastic composite package having a folded and sealed package bottom. The lid can then be designed uniformly with the cardboard / plastic composite package and offers by peeling - and thus exposing the entire cross section of the carton / plastic composite package - the possibility of lumpy parts containing products as a whole and gently the carton / plastic composite package remove .

It was surprisingly found that the cardboard / plastic composite pack has sufficient stability to meet the requirements of production and distribution and sales.

This can be particularly advantageous

Cardboard / plastic composite packaging can also be used for products that are not predominantly liquid in character. Such is the use of the carton / plastic composite package according to the invention for receiving yogurt and other chunky foods containing suitable. These can then be eaten directly after removing the lid from the cardboard / plastic composite package. For example, any vegetable or meat products can be "carefully" removed through the large packaging opening.

Another advantage of the invention is that the cover can contribute to a consistent and attractive appearance of the cardboard / plastic composite package by appropriate designs such as printing.

In a particularly preferred embodiment of the packing jacket is made of a rectangular blank, since a waste-free production is guaranteed.

According to another teaching of the invention, the lid may consist of a film or a cardboard / plastic composite material. This makes the cover particularly easy and inexpensive to produce.

The web can preferably be formed from the upper region of the packing jacket. For example, the web may be a mouth roll made from the paperboard / plastic composite packaging material. Alternatively, the web of cardboard / plastic composite packing material may also be folded.

In a further embodiment of the invention, it is possible that the web is arranged on a frame connected to the upper region of the packing jacket. In particular, the lid on the web before or after connecting the frame to the upper portion of the Packing mantle be attached. The frame can be manufactured by injection molding. Thus, a variety of forms can be realized inexpensively.

A particularly preferred embodiment is characterized in that the lid is welded onto the web. However, the lid can also be glued or sealed.

Regardless of how the lid is mounted on the web, the lid can be made resealable, so that after a partial removal of the product, the remaining part is still protected.

Furthermore, the packing jacket can be printed. As a result, a particularly sales-promoting effect can be achieved. For printing, all known methods can be used. The invention is not limited to any particular form of oppression. In particular, the printing of any interlayer and / or cover layer of the packing material is encompassed by this invention.

By appropriate shaping of the cross section of the packing jacket, in particular round, oval or rectangular with or without rounded edges, a wealth of different types of cardboard / plastic composite packaging can be produced. The shapes can be adapted to the product and to the desired external effect and presentation.

Furthermore, it is thus possible to provide particularly favorable forms for transport and storage logistics, the transport and storage of as many as possible Allow cardboard / plastic composite pack in the lowest possible volume. By parallel running levels of package bottom and lid, the composite package according to the invention can also be well stacked.

Particularly advantageous, the package bottom can be made rectangular, for example folded as a flat gable. The bottom of the package can thus be particularly stable, whereby each carton / plastic composite package can stand securely even in the open state. Thus, the cardboard / plastic composite pack can be discontinued during consumption or removal of the product, without the product can escape.

In another embodiment, an additional protective cover may be provided, wherein the protective cover can close the cardboard / plastic composite package after opening the lid again.

Thus, the consumer can easily close a once opened cardboard / plastic composite pack again and thus ensure the freshness of the remaining product.

In particular, the protective cover with the cardboard / plastic composite pack can be positively locked (cuff lid), but also welded, glued or sealed.

When providing a frame, a secure locking of the protective cover on the frame can be accomplished by special design of the frame. Particularly advantageous for the frame is designed so that it has at least one element for locking the protective cover.

The frame may have at least one circumferentially arranged recess for locking the protective cover. However, it is also possible that the frame has at least one circumferentially arranged projection for locking the protective cover.

In this case, a good grip of the protective cover can be ensured by special choice of the projections and recesses and also the material required for the production of the frame can be minimized.

Procedurally, the solution of the problem is solved by the following steps:

Making a blank from a

Composite sheet

Seal two edges of the blank to one

Longitudinal seam, so that a packing jacket is formed,

Providing a circumferential web on the packing jacket,

Make a container open on one side

Applying a cover to the bridge,

Sterilizing the container open on one side over the

Bottom opening, optionally turning the container open on one side, bottom-side filling of the container open on one side with a product and

Folding and welding the container bottom to a sturdy packing bottom. Alternatively, the solution to the problem is solved procedurally by the following steps:

Making a blank from a

Composite sheet

Seal two edges of the blank to one

Longitudinal seam, so that a packing jacket is formed,

Make a container open on one side

Folding and welding the container bottom into a stable package bottom,

Providing a circumferential web on the packing jacket,

Sterilizing the unilaterally open container via the upper end of the packing jacket,

Fill the unilaterally open container with a

Product,

Sterilize a lid and

Applying the lid to the bridge.

Another alternative provides the following steps:

Making a blank from a

Composite sheet

Seal two edges of the blank to one

Longitudinal seam, so that a packing jacket is formed,

Unfolding the wrapper,

Make a container open on one side

Apply a lid to the unfolded

Pack casing,

Sterilization of the container open on one side over the bottom opening, if necessary rotating the one-sided open

container Bottom filling the unilaterally open container with a product and folding and welding the container bottom to a stable package bottom.

Thus, there are three methods for solving the problem: it is thus possible first to apply a lid, to fill the cardboard / plastic composite pack in a later step and then to produce the bottom of the pack or first to produce the bottom of the pack, in a later step the cardboard / plastic Fill compound pack and then apply the lid.

In this case, in the aforementioned method, all the features of the article according to the invention can be produced, such as the cross-sectional shape of the packing jacket, the folding of the package bottom and its stable design, welding the lid and printing the lid and the packaging jacket.

The bottom of the container can be folded particularly easily if the blank before the longitudinal seam formation with Rillbzw. Folding lines is provided. In particular, the package bottom can thus be made rectangular in a simple form.

Due to the fact that the bottom of the package is first provided with a bottom seam and that subsequently the packing ears formed during folding are pressed onto the bottom of the package and fastened thereon in such a way that the bottom surface is concavely arched, a particularly sturdy package bottom can be produced. Plastic composite pack in the Essentially, just stand on the outer four edges of the bottom of the pack.

In terms of apparatus, the object is achieved by a deployment station in which the flattened packing shells are unfolded into a tube-like packing sheath and fed to a mandrel by a lid application station, in which a lid is connected to a packing sheath to form a one-sided open pack, and to a transfer station, in which the pack (P) is removed from the mandrel and passed to a downstream filling unit.

According to a further advantageous embodiment of the invention, the lid-applying station is arranged distributed over a plurality of mandrel positions. In this way, the required processing time of the cyclically operated mandrel wheel can be increased accordingly.

This is particularly necessary if, prior to the actual application of the lid, the outer edge of the packing jacket is rolled forward in a first station, formed into a mouth roll in a second station, heated in a third station and pressed in a fourth station to a web, such as it is provided according to a further preferred embodiment of the invention. In order to obtain these stations, mandrel wheels with a corresponding number of spikes, for example six or eight, are expediently to be used.

According to a further teaching of the invention, a web press station is provided, in which a pressing punch is pressed axially onto the mandrel for pressing the mouth roll and to generate the back pressure two supports are applied to the side of the mandrel. These supports are pivotally mounted in an advantageous manner and arranged in its working position positively around the mandrel with the sheath pushed thereon.

The actual lid is then applied according to a further preferred embodiment of the invention in a lid sealing station in which each lid of a foil strip which is perpendicular to the mandrel wheel level, punched out and sealed onto the web.

As already described in detail above, it is also possible for the stiffening of the container, the lid is not connected directly to the container, but with a frame first to a frame cover, which is then applied to the unilaterally open container. Depending on the geometry and application, in such an embodiment, first the frame cover or the unfolded packing jacket is pushed onto a mandrel of a mandrel wheel and then the other part before frame cover and packing jacket are connected to a container open on one side.

The invention will be explained in more detail with reference to a drawing illustrating only preferred embodiments. In the drawing show

FIGS. 1 to 6 represent intermediate steps in the production of the cardboard / plastic composite package according to the invention. FIGS. 7 to 17 show further embodiments.

Fig. 1 shows a blank 1, which is made of a composite material web. For cutting all known methods, such as water jet cutting or punching can be used. Furthermore, the composite material web can have different layers and be printed. Particularly advantageous is a blank 1 is selected with a rectangular format, as a waste-free production is guaranteed. Furthermore, the blank 1 Rillbzw. Folding lines 2 on. By creasing or folding lines 2, a subsequent folding of the blank 1 is considerably simplified. Fig. 2 shows that the blank 1 is placed around a mandrel 3 and two edges 4 and 5 of the blank 1 are sealed to form a longitudinal seam 6.

As shown in Fig. 2A, it is advantageous if in this case the inner, that is applied to the mandrel 3 edge 5 is peeled executed. For this purpose, the edge 5 is first peeled off in an area on the side facing away from the mandrel 3 side. Subsequently, the edge 5 is folded over and optionally secured so that one half of the peeled area rests on the other half. Thus, it can be easily prevented that later the product comes into contact with the carton of the blank 1. Furthermore, such a later complete sterilization can be ensured.

As shown in Fig. 2B, the edge 5 can also be protected by an overlapping sealing strip 7, which may also be sealed. Furthermore, as shown in Fig. 2C, the sealing strip 7 may also be arranged in a U-shape around the edge 5. In particular, can be attached to the edge 5 by a follower sealing strip 7 already in the production of the blank 1 of the sealing strip.

The longitudinal seam sealing produces, depending on the shape of the mandrel 3, a packing jacket 8. FIG. 2 shows a substantially rectangular cross section of the package jacket 8 with rounded edges 9. The packing jacket 8 is still open at its two ends. Alternatively, depending on the shape of the mandrel 3, for example, round or oval cross sections can also be produced. Fig. 3 shows an embodiment in which a circumferential web 10 from the upper portion of

Packungsmantels 8 is formed. In Fig. 3, the web 10 is a produced from the cardboard / plastic composite packaging material mouth roll 12, the production of which is explained in FIGS. 3A to 3C.

As shown in Fig. 3A fragmentary, first the upper end 11 of the packing jacket 8 is rolled in the direction of the arrow A. In the step shown in FIG. 3B, the rolled packing jacket 8 is pressed in the direction of the arrows B, so that the mouth roll 12 shown in FIG. 3C is formed.

FIG. 4 shows a container 13 which is open on one side and which is formed by a lid 14 which is welded onto the web 10 of the mouth roll 12. Thus, the upper end 11 of the packing jacket 8 is closed. In this embodiment, the lid 14 in addition to a Abziehlippe 15, which allows easier removal of the lid 14.

Furthermore, the lid 14 may be reclosed.

Starting from a unilaterally open container 13, as shown in Fig. 4, the not shown intermediate step of sterilization follows. For sterilization, all known methods can be used, as long as they do not claim the materials of the packing jacket 8, the lid 14 or their compounds as needed. In particular, autoclaving is suitable. Fig. 5 shows a unilaterally open container 13, which is rotated relative to the position shown in Fig. 4, so that the still open end 16 of the packing jacket 8 is directed upward. The product 17 was filled through the open end 16 into the unilaterally open container 13. The lid 14 prevents leakage of the product 17. The filling can be done by any known method.

FIG. 6 shows that the previously open end 16 of the packing jacket 8 is folded into a stable package bottom 18 with packing tubes 19. For this purpose, the open end 16 was first provided with a bottom seam and attached to the pack bottom 18 the packing ears 19 which subsequently formed during folding. In particular, it is advantageous if the packing tubes 19 are pressed onto the package bottom 18 in such a way and fixed thereon, that the bottom surface is concavely curved. Then arrive at the parking of the cardboard / plastic composite pack only the outer four edges of the package bottom 18 to the support, resulting in a particularly stable state.

In Fig. 7, an alternative to the formation of the web 10 from the upper portion of the packing jacket 8 by providing a fold 20 is shown.

As shown in FIG. 7A, the upper end 11 of the packing jacket 8 is first folded around a first point P in the direction of the arrow A for this purpose. In the next step, shown in Fig. 7B, the once folded part of the package jacket 8 is folded a second time around the point Q in the direction of the arrow B. After that, the folding 20, as shown in Fig. 7C, are strengthened in the direction of the arrows C by pressing in itself. In this case, the lid 14 described above can be attached at the same time.

Fig. 8 shows that a web 10 can also be configured by outwardly folding the upper end 11 of the packing jacket 8. In this alternative, either initially only the fold 20 can be pressed or at the same time a lid 14 are attached.

A further possibility for arranging a peripheral web 10 at the upper end 11 of the packing jacket 8 is provided by arranging the web 10 on a frame 21 connected to the upper region of the packing jacket 8, as will be explained below. The frame 21 has the same reference numerals in the embodiments shown, although it may differ in each case in design and material.

In the embodiment shown in FIG. 9, the web 10 is formed on a frame 21 connected to the upper region of the packing jacket 8. For this, the frame 21 is provided with an L-shaped profile and fixed by crimping the upper end 11 to the packing jacket 8. In this embodiment, a lid 14 may have been secured to the web 10 before the frame 21 is secured to the packing jacket 8. In the embodiment shown in Fig. 9, however, the lid 14 is first mounted in a subsequent step, not shown, and thus in turn made a container 13 open on one side. For fixing the frame 21 shown in FIG. 10, it is only necessary to fasten the frame 21 to the upper end 11 of the packing jacket 8, in contrast to the embodiment previously shown. A complex folding of the upper end 11 can be omitted, which considerably simplifies the production. The attachment of a lid 14 on the web 10 can in turn be made before or after the attachment of the frame 21 at the upper end 11 of the packing jacket 8.

A particularly stable embodiment of a frame 21 is shown in FIG. 11. In particular, by the stop 22 of the frame 21, the frame 21 can be particularly easily positioned, since the insertion depth of the frame 21 is limited in the upper end 11 of the packing jacket 8 by the stopper 22.

Once the lid 14 has been withdrawn, especially if it has not been resealable, it may be advantageous to provide an additional protective cover 24. For the protective cover 24 described below, the same reference numeral is used in each case. However, in particular the shape and the material used for the production of the protective cover 24 may each be designed differently.

Fig. 12 shows a plan view of a particular embodiment of the frame 21. The frame 21 has elements for latching the protective cover 24, which is shown in Fig. 14. These are four, arranged by dashed lines, circumferentially arranged recesses 23, which of course can be made differently dimensioned. In Fig. 13 it is shown how the frame 21 is fixed in the upper region of the packing jacket 8. This embodiment is particularly compact, so that several cardboard / plastic composite packages can be placed side by side in a particularly dense and space-saving manner. In the recesses 23, as shown in Fig. 14, the protective cover 24 engage and lock. For this purpose, the protective cover 24 four beads 25, which serve to engage in the four recesses 23 of the frame 21 and for locking the protective cover 24 with the frame 21. Thus, even after removal of the cover 14 previously fastened on the web 10, the cardboard / plastic composite packing can be closed again.

Another embodiment of a frame 21 with an element for latching a protective cover 24 is shown in FIGS. 15 and 16. The frame 21 has a circumferential projection 26 which serves for latching a correspondingly designed protective cover 24. From Fig. 16 shows that the projection 26 protrudes beyond the outer cross section of the packing jacket 8.

As shown in FIG. 17, the frame 21 may also have a plurality of peripherally arranged projections 26 for latching a protective cover 24. Thus, the required material for the production of the frame 21 can be reduced in a simple manner and thus costs can be saved.

In Fig. 18, a first example of an apparatus for producing a one-sided open container P is shown schematically. It consists first and essentially of a mandrel wheel 27 with eight mandrels 28. In a Auffaltstation 29 is made of a flattened Packing jacket S initially a tubular packing jacket 8 unfolded and pushed axially onto a free mandrel 28. The Auffaltstation 29 close in the next positions of the mandrel wheel a Vorrollstation 30, a Endrollstation 31, a heating station 32, a Stegpressstation 33, a lid sealing station 34 and finally a transfer station 35 at. In order not to expose the container to be produced P unnecessary soiling, the device is encapsulated by a housing 36 having at least one opening 36. The opening (s) 36 serves this to supply the flattened packing sheaths S delivered stacked in a magazine 38. The flattened packing sheath S is unfolded into a tubular packing sheath 8 by means of a gripper 39 and further aids, the cross section of the unfolded packing sheath 8 being unfolded corresponds to the cross section of the mandrel 28. For better clarity, this process is schematically shown in Fig. 19 again in perspective.

In the Vorrollstation 30 first provides a mold 4OA for the Vorroll the upper edge of the package, wherein the mold 4OA is pressed axially by an unspecified, for example, pneumatically operated device on the mandrel 28. It is understood that in this case the packing jacket must be supported towards the Dornradachse, even if this is not shown in the schematic drawing.

The pre-rolled package edge is then formed in the end roll station 31 by a further mold 4OB to a mouth roll 12. This is heated in the heating station 32 by a corresponding heater 41 and finally fed to the subsequent web press station 33. There, in the illustrated preferred embodiment from below, a punch 42 against the mandrel 12 is pressed axially, wherein the upper edge of the mandrel 12 is supported by correspondingly supplied back pressure supports 43A, 43B, so that here the desired flat web 10 is formed. In Fig. 18, when the counter-pressure supports 43A and 43B are pivoted in the mandrel wheel plane, this serves only for better illustration. In order not to restrict the movement of the mandrel wheel, the counter-pressure supports 43A and 43B move in a plane perpendicular to the plane of the mandrel wheel 27, as shown in FIG.

Finally, provided with the web 10 packing jacket 8 is provided in the lid sealing station 33 with a lid L, so that a container P open on one side is formed. The required lid L are for this purpose punched out of a perpendicular to the mandrel wheel level foil strip F, as shown schematically in Fig. 21. By this embodiment, each lid L can be provided with a suitably arranged on a corner tear tab T, which projects beyond the web 10 and is provided for easier opening of the container P. The sealing is then done by means of a seal punch 44, wherein the lid L is punched out in advance with a stamp only schematically drawn so that it still remains in the film strip F, but is reliably separated during the sealing process of this.

However, as already mentioned, it is also possible, instead of the web used, to use a frame 21 into which or onto which the actual lid L is welded is. These may be frames 21, whose outer dimensions are smaller than the inner clear cross-section of the unfolded packing jacket 8, as shown in Fig. 10, or are larger or equal, as shown in Fig. 11. For the manufacture of such containers, two alternative devices are shown in FIGS. 22 and 23. Identical parts are numbered here by the same reference numerals. In the first alternative according to FIG. 22, a mandrel wheel 46 with four spikes 47 initially consists of an unfolding station 28, and of a frame top loading station 49, a frame top sealing station 50 and finally a transfer station 51. Again, a housing 52 for encapsulation with a corresponding opening is provided 53 is provided, through which a magazine 54 is supplied with flattened pack coats S. In the unfolding station 28, the unfolding of the packing shells 8 takes place by means of a gripper 55 in the manner already described in more detail with reference to FIG.

The unfolded packing jacket 8 is then pushed onto the mandrel 47 and pivoted into the frame cover attachment station 49. There is a magazine 56 with a plurality of already finished sealed frame lids FL, of which by means of a pivoting unit 57 and corresponding grippers 58 each a frame cover FL is removed, is pivoted by 180 ° and then placed axially in the mandrel direction on the packing jacket 8 ,

After a renewed pivoting movement of the patch frame cover FL is liquid-tightly connected to the packing jacket 8 by means of a seal stamp 59, as also apparent from Fig. 24. The last position now shows the Transfer station 51, in which the unilaterally open container P is withdrawn by means of a pivoting unit 60 from the mandrel 47 and a support chain 61 is fed, with appropriately arranged retaining clips 62 are provided for fixing the now open at its lower end, as it were upside-down packages.

If now smaller frame cover FL 'used whose outer diameter is smaller than the inner diameter of the unfolded packing jacket 8, the completion takes place in a slightly different device, in the first a frame cover FL' from a magazine 56 'by means of a pivoting unit 57' and a Gripper 58 'is placed on the correspondingly shaped end of a mandrel 47'. In dash-dotted circle in Fig. 23 can be clearly seen that on the mandrel 47 'patch frame cover FL' may be provided with a lid, which also has a pull tab T, which is then, however, conveniently folded inwards. In this context, reference is also made to Fig. 25, which corresponds to Fig. 10, but with the lid L and Auflißlasche T is provided.

After the spike 47 'then further from the

Frame cover placing station 49 'has been pivoted into the Auffaltstation 48', a packing jacket 8 is pushed over the lid FL ', which has been previously removed by means of a gripper 55' and a pivot unit 55A a magazine 54 'and unfolded. The last two stations (frame lid sealing station 50 and transfer station 51) correspond to the device of FIG. 22, so that reference can be made to the corresponding description. In the illustrated preferred embodiment, the pivoting unit 60, which serves to pull off the finished unilaterally open container P ', simultaneously used for pushing the unfolded packing shells 8 by being designed as a pivot unit 60' double and mechanically coupled together.

However, the present invention is not limited to the aforementioned embodiments. For example, different cross-sectional shapes may also be provided for both ends of the cardboard / plastic composite package. Thus, the package bottom may be substantially rectangular, the area of the mouth roll may be substantially circular. The packing jacket then passes from a rectangular to a circular cross section and the lid to be welded is adapted to the circular cross section.
