PACKAGING COMPOSED OF CARDBOARD AND SYNTHETIC MATERIAL, WITH

REMOVABLE COVER, AS WELL AS PROCESSES FOR ITS MANUFACTURING.

[0001] The present invention relates to a package composed of cardboard and synthetic material of a packaging liner provided with a longitudinal seam, and with a folded and welded packaging bottom, provided at one end of the packaging liner, as well as, refers to two processes for its manufacture.

[0002] Packaging made of cardboard and synthetic material has been known for a long time, and can be purchased on the market in multiple shapes and shapes. For example, they serve as beverage packaging or also as packaging for other foodstuffs.

[0003] It is known to equip the packaging with an opening aid, in order to facilitate access to the product for the consumer. For this purpose, in the upper area of the packaging made of cardboard and synthetic material, in general, an element is provided, which covers an opening for pouring provided in the packaging material made of cardboard and synthetic material. The pouring opening serves to empty the product.

[0004] In the case of the element that covers the opening to dump it can be a pulling strip, which releases the opening to dump during the removal.

[0005] In addition, it is known to fix a frame that covers the opening to pour into the packaging made of cardboard and synthetic material. The frame may have a lid, which during opening releases the opening to pour. In turn, between the lid and the opening for pouring, a strip may be provided, which at the first opening of the lid needs to be removed in order to reach the product.

[0006] Alternatively, before the first opening, the lid can be connected, in one piece, with the frame. At the first opening, the lid is then partially separated from the frame, and releases the opening to pour.

Petition 870180036286, of 05/03/2018, p. 8/25

2/13 [0007] In addition, the frame can also be equipped with a spout for pouring and thus can serve as an aid for pouring.

[0008] The frame can also have a tube equipped with a thread, to which a screw cap can be threaded. In particular, the screw cap is used so that at the first opening a perforation in the packaging material composed of cardboard and synthetic material is broken and thus the opening for pouring is produced.

[0009] The elements mentioned above, for covering the opening for pouring, can be carried out, in particular, in such a way that they again make it possible to close the packaging made of cardboard and synthetic material.

[00010] In the case of the well-known packaging made of cardboard and synthetic material, it is disadvantageous that, due to the very small opening for pouring, they are only suitable for liquid content. In addition, the well-known packaging made of cardboard and synthetic material cannot be stacked well with elements for dumping mounted upwards, and therefore cannot be optimally arranged in a small space for transport and / or storage.

[00011] US-A-5 236 120 discloses a package made up of cardboard and synthetic material of a packaging coating, and with a folded and welded packaging bottom, provided at one end of the packaging coating. This packaging is closed by a lid, which is removably fixed, which closes the opening that releases almost the entire cross section. The shape of the upper edge of the known composite package is of expensive construction.

[00012] Another packaging container with a lid that closes the entire cross section is known from DE-A1-3 641 385. In the case of this known packaging, the upper edge of the composite package consists of a curled edge on which a lid is sealed

Petition 870180036286, of 05/03/2018, p. 9/25

3/13 removable. It is also expensive to manufacture the rolled edge.

[00013] The invention, therefore, has the task of indicating a packaging composed of cardboard and synthetic material, assembled with simple construction, which is also suitable for non-liquid products and which, in addition, can be well stacked.

[00014] This task, with respect to the packaging composed of cardboard and synthetic material according to the invention, is solved by the fact that, on the upper end of the packaging lining, a surrounding edge is arranged, and by the fact that, on the edge is a removable cover is provided, and the fact that the edge is arranged in a frame connected with the upper area of the packaging lining.

[00015] With this, the invention recognized that, through the provision of an edge, a lid can be removably fixed in a packaging made of cardboard and synthetic material with a folded and welded bottom of the packaging. The lid, then, can be molded in one piece with the packaging made of cardboard and synthetic material, and offers, through the removal - and with that, the release of the entire cross section of the packaging made of cardboard and synthetic material - the possibility of removing also products that contain parts in pieces as a whole and saving the packaging made of cardboard and synthetic material.

[00016] In this case, surprisingly, it was found that the packaging made of cardboard and synthetic material has sufficient stability to live up to the requirements of production, as well as distribution and sale.

[00017] With this, in a particularly advantageous way, a packaging made of cardboard and synthetic material can also be used for products, which are not predominantly liquid. Thus, the use of packaging made of cardboard and synthetic material according to the invention, is suitable for receiving yogurt and other

Petition 870180036286, of 05/03/2018, p. 10/25

4/13 foods containing pieces in pieces. These foods, then, can also be eaten directly, after removing the lid from the packaging made of cardboard and synthetic material. For example, through the large opening of the packaging, any vegetable or meat products can also be carefully removed.

[00018] Another advantage of the invention is that, the lid always flat can contribute, through corresponding configurations such as prints, to a homogeneous and attractive exterior of the packaging made of cardboard and synthetic material.

[00019] In a particularly preferred embodiment, the packaging lining is made of a rectangular cut-out piece, as this ensures a waste-free production.

[00020] According to another teaching of the invention, the cover can be made of a plastic sheet or a material composed of cardboard and synthetic material. Thus, the lid can be manufactured in a particularly simple and low cost manner.

[00021] According to the invention, the edge is arranged in a frame connected with the upper area of the packaging lining. In particular, the lid can be attached to the edge before or after the frame is attached to the upper area of the packaging liner. The frame can be manufactured in the injection casting process. Thus, a multitude of ways can be performed at low cost.

[00022] A particularly preferred embodiment is characterized by the fact that the lid is welded on the edge. However, the lid can also be glued or sealed.

[00023] Regardless of the fact that, as the lid is fixed on the edge, the lid can be executed and can be closed again, so that after removing the product the part that remains will continue to be protected. It is already well known from US-A-3 272 422 a composite package with a lid that can be closed again.

Petition 870180036286, of 05/03/2018, p. 11/25

5/13 [00024] In addition, the packaging lining can be printed. With this, a particular marketing effect is obtained. All known processes can be used for printing. The invention is not limited to any form of printing. In particular, the printing of a possible intermediate layer and / or cover layer of the packaging material is covered by this invention.

[00025] By means of the corresponding molding of the cross section of the packaging lining, in particular, round, oval or rectangular with or without rounded corners, a packaging filling made of cardboard and synthetic of different type can be manufactured. In this case, the shapes can be adjusted to the product and the desired exterior effect and presentation.

[00026] In addition, in this way, for transport and storage logistics, particularly advantageous forms can be envisaged, which make it possible to transport and store many possible packages composed of cardboard and synthetic material in the smallest possible volume. Through parallel executed plans, the bottom of the package and the lid, the composite package according to the invention, in addition, can be well stacked.

[00027] Particularly advantageously, the bottom of the package can be made rectangular, for example, it can be folded as a flat tip. With this, the bottom of the package can be arranged, in particular, stable, so that each package composed of cardboard and synthetic material alone can be safely stable also in the open state. Thus, during ingestion or removal of the product, the packaging made of cardboard and synthetic material can be disposed of, without the product being able to leave.

[00028] In another embodiment, an additional protective cover may be provided, and the protective cover may close the packaging made of cardboard and synthetic material again after opening the cover.

Petition 870180036286, of 05/03/2018, p. 12/25

6/13 [00029] Thus, the consumer can re-close a package made of cardboard and synthetic material opened once, in a simple way, and thus, ensure that the remaining product remains fresh.

[00030] In particular, the protective cover can be snapped into place due to the shape of the packaging made of cardboard and synthetic material (inverted cover), but it can also be welded, glued or sealed.

[00031] In the case of the provision of a frame, by means of the special execution of the frame, it is possible to secure the protective cover securely in the frame. For this purpose, the frame is particularly advantageous in such a way that it has at least one element for fitting the protective cover.

[00032] The frame may have at least one recess arranged around it, for fitting the protective cover. However, it is also possible that the frame has at least one protrusion arranged around it for the fitting of the protective cover.

[00033] In this case, through the special choice of shoulders and recesses, a good retention of the protective cover can be guaranteed and, in addition, the material necessary for the manufacture of the frame can be kept to a minimum.

[00034] According to the process, the solution of the task is solved through the following steps:

- production of a piece cut out of a strip of composite material,

- sealing of two corners of the cut piece to form a longitudinal seam, in such a way that a coating of the packaging is formed,

- provision of a border around the packaging lining,

- production of an open container on one side by placing a lid on the edge,

- sterilization of the open container on one side, through the bottom opening,

- possible rotation of the open container on one side,

Petition 870180036286, of 05/03/2018, p. 13/25

7/13

- filling on the bottom side of the open container on one side, with a product and

- folding and welding the bottom of the container to form a stable packaging bottom.

[00035] Alternatively, the solution of the task according to the process is solved through the following steps:

- production of a piece cut out of a strip of composite material,

- sealing of two corners of the cut-out piece to form a longitudinal seam, in such a way that a covering of the packaging appears,

- production of an open container on one side by folding and welding the bottom of the container to form a stable packaging bottom,

- provision of a border around the packaging lining,

- sterilization of the open container on one side, through the upper end of the packaging lining,

- filling the open container on one side with a product,

- sterilization of a lid and

- placing the lid on the edge.

[00036] With this, two processes are given for the solution of the task: first, therefore, a lid can be placed, in a next step the packaging made of cardboard and synthetic material is filled, and then the bottom of the packaging is manufactured, or first the bottom of the packaging is manufactured, in a next step the packaging made of cardboard and synthetic material is filled, and then the lid is placed.

[00037] In this case, in the aforementioned processes, all the characteristics of the object according to the invention can be manufactured, such as, for example, the shape of the packaging lining cross-section, the folding of the packaging lining and its stable execution, the welding the lid and printing the lid and packaging liner.

Petition 870180036286, of 05/03/2018, p. 14/25

8/13 [00038] In a particularly simple way, the bottom of the package can be folded if, before forming the longitudinal seam, the cut piece is equipped with groove or fold lines. In particular, the bottom of the package can be made in a simple rectangular shape.

[00039] Due to the fact that the bottom of the package is first equipped with a bottom seam and that then the flaps of the package that appear during folding are compressed on the bottom of the package and are fixed in such a way on that bottom, that the bottom surface is concave convex, a particularly stable packaging bottom can be manufactured, since, in this way, the packaging made of cardboard and synthetic material stands, essentially, only in the four outer corners of the packaging bottom.

[00040] The invention will be explained in more detail below, with the aid of a drawing that represents only preferred examples of execution. In the drawing are shown in figure 1 - a piece cut out of a strip of composite material, in figure 2 - a coating of the packaging on a mandrel in the horizontal cut, in figures 2A to 2C - several executions of a longitudinal seam, in figure 3 - a bottom of the package in a top view from below, in figure 4 - a coating of the package with a frame placed, shown only partially, in the vertical section, in figures 5 and 6 - other examples of execution of the packaging coating of the figure 4, in figure 7 - a frame with an edge, in the top view, in figure 8 - a vertical section of the frame along line XIII - XIII in figure 7, in figure 9 - the frame of figures 7 and 8 with a protective cover fitted, in vertical cut,

Petition 870180036286, of 05/03/2018, p. 15/25

9/13 in figure 10 - another way of making a frame, in the top view, in figure 11 - a vertical section of the frame along line XVI - XVI in figure 10 and in figure 12 - another way of making of a frame, in the top view.

[00041] Figures 1 to 3 represent intermediate steps during the manufacture of the packaging made of cardboard and synthetic material according to the invention. Figures 4 to 12 represent other forms of execution.

[00042] Figure 1 shows a cut-out piece 1, which is produced from a strip of composite material. For cutting, all known processes such as water jet cutting or stamping can be used. In addition, the strip of composite material may have several layers, and be printed. In a particularly advantageous way, a cut piece 1 is chosen with a rectangular shape, since, in this way, a waste-free production is ensured. In addition, the cut-out part 1 has groove or fold lines 2. By means of the groove or fold-up lines 2 a posterior folding of the cut-out part 1 is considerably simplified.

[00043] Figure 2 shows that the cut piece 1 is placed around a mandrel 3, and two corners 4 and 5 of the cut piece 1 are sealed to form a longitudinal seam 6.

[00044] As shown in figure 2A, it is advantageous if, in this case, the corner 5, which is internal, therefore, adjacent to the mandrel 3 is executed peeled. To do this, the corner 5 is peeled off in an area, firstly, on the side away from the mandrel 3. Then, the corner 5 is folded and fixed eventually so that one half of the peeled area is on the other half, respectively. With this, in a simple way, it can be avoided that, later on the product comes in contact with the cardboard of the piece

Petition 870180036286, of 05/03/2018, p. 16/25

10/13 cut-out 1. In addition, complete posterior sterilization can be guaranteed in this way.

[00045] As shown in figure 2B, the corner 5 can also be protected by an overlapping sealing strip 7, which can likewise be sealed. In addition, as shown in figure 2C, the sealing strip 7 can also be arranged in a U shape, around the corner 5. In particular, through a sealing strip 7 that runs together, even during the manufacture of the cut-out part 1, the sealing strip 7 can be attached to the corner 5.

[00046] By sealing the longitudinal seam, depending on the shape of the mandrel 3, a coating of the package 8 is formed. In Figure 2, a substantially rectangular cross-section of the coating of the package 8 is shown, with rounded corners 9. In this case, the casing of the package 8 is still open at its ends. Alternatively, then, depending on the shape of the mandrel 3, round or oval cross sections can also be produced, for example.

[00047] Figure 3 shows that the previously opened end of the wrapping of the package 8 is folded to form a stable bottom of the package 18 with flaps of the package 19. For this, the open end 16 was first equipped with a bottom seam and then, the flaps of the carton 19 arising during folding were fixed to the bottom of the carton 18. In particular, it is advantageous if the flaps of the carton 19, in this case, are compressed on the bottom of the carton 18 and are fixed on that bottom of the carton. such that the bottom surface is concave convex. Then, during the placement of the carton composed of cardboard and synthetic material, only the four outer corners of the bottom of the carton 18 are able to reach the support, which leads to a particularly stable position, of the projecting extraction lip 15 not shown in figure 3.

[00048] A surrounding edge 10 is arranged at the upper end 11 of the casing 8, in that the edge 10 is arranged in a frame 21 connected with the upper area of the casing.

Petition 870180036286, of 05/03/2018, p. 17/25

11/13 packaging 8, as will be explained below. In the execution examples shown, frame 21 has the same reference number, although it can differ, respectively, in shape and material.

[00049] In the execution example shown in figure 4, the edge 10 is executed in a frame 21 connected with the upper area of the packaging liner 8. For this, the frame 21 is provided with an L-shaped profile, and is fixed through the edge of the upper end 11 on the packaging liner 8. In this embodiment, the lid 14 is only placed on the frame 21 in a next step not shown, and thus, in turn, an open container 13 is produced from one side.

[00050] For fixing the frame 21 shown in figure 5, as opposed to the execution example shown above, it is only necessary to fix the frame 21 on the upper end 11 of the packaging liner 8. Expensive folding of the upper end 11 can be abolished , which considerably simplifies manufacturing. The fixing of a lid 14 on the edge 10, in turn, can be carried out before or after the frame 21 at the upper end 11 of the packaging liner 8.

[00051] A particularly stable embodiment of a frame 21 is shown in figure 6. In particular, through the backrest 22 of the frame 21, the frame 21 can be positioned in a particularly simple way, since the depth of fitting of the frame 21 at the upper end 11 of the casing 8 is limited by the stop 22.

[00052] As soon as the cover 14 has been removed, in particular, when that cover has not been executed and can be closed again, it may be advantageous to provide an additional protective cover 24. For the protective cover 24 described below, the same reference number is used respectively. However, in particular, the molding as well as the material used for the manufacture of the protective cover 24 can be carried out, respectively, in another way.

Petition 870180036286, of 05/03/2018, p. 18/25

12/13 [00053] Figure 7 shows a top view of a special embodiment of the frame 21. The frame 21 has elements for fitting the protective cover 24, which is shown in figure 14. In this case, it is it has four recesses 23 arranged around, represented by dashed lines, which of course can also be executed in a different way.

[00054] Figure 8 shows how the frame 21 is attached to the upper area of the packaging lining 8. This form of execution is particularly compact, in such a way that several packages made of cardboard and synthetic material can be placed side by side. the other in a particularly close way, and saving space. As shown in figure 9, in the recesses 23 the protective cover 24 can engage and engage. For this purpose, the protective cover 24 has four edges 25, which are used to engage the four recesses 23 of the frame 21, and for fitting the protective cover 24 with the frame 21. Thus, also, after removing the cover 14 previously fixed on the edge 10, the packaging made of cardboard and synthetic material can be closed again.

[00055] Another way of making a frame 21 with an element for fitting a protective cover 24 is shown in figures 10 and 11. The frame 21 has a surrounding shoulder 26, which serves to fit a cover protection 24 performed accordingly. From figure 11 it can be seen that the shoulder 26 projects outwards through the outer cross section of the packaging liner 8.

[00056] As shown in figure 12, the frame 21 can also have several ridges 26 arranged around it, for fitting a protective cover 24. Thus, in a simple way, the material needed for the manufacture of the frame 21 can be reduced and This saves costs.

[00057] The present invention, however, is not restricted to the previously mentioned examples of execution. For example,

Petition 870180036286, of 05/03/2018, p. 19/25

13/13 also different shapes of the cross section for the two ends of the packaging made of cardboard and synthetic material. Thus, the bottom of the package can be made essentially rectangular, the area of the mouth roll can be made essentially of circular shape. The packaging liner then passes from a rectangular cross section to a circular cross section, and the cap to be welded is adapted to the circular cross section.
