The packing container

 

(57) Abstract:

Usage: the invention relates to the field of packaging. The inventive packaging container made of a material containing a supporting layer of plastic and filler, put in plastic in an amount of from 50 to 80% of the total mass of the base layer. To facilitate opening of the container it is provided with a line of weakened strength, made in the packaging material, along which the container material must be separated for opening holes. The line of weakened strength is a partial cut in the bearing layer or similar linear recess, weakening the material, with a depth of only about 10 - 30% of the total thickness of the base layer, which reduces the tear resistance of the base layer 60 to 80%. 10 C.p. f-crystals, 3 ill.

The invention relates to a packaging container made of flexible packaging material by thermoforming, flexible molding or other mechanical processing, and having a line of weakened strength tear along part of the wall with the formation of holes for discharging the contents of the container.

For a long time apply ready-to-use disposable uptyh layers of paper or paperboard and outer layers of plastic, usually polyethylene. Disposable packaging at the present time, typically manufactured using modern productive packaging machines, which simultaneously form, fill and seal packaging on an industrial scale.

From, for example, strips of packaging material, such disposable packaging is made by, first, the manufacture of pipe by connecting with each other of the two longitudinal edges with the formation of the longitudinal seam overlap. The pipe is filled with relevant content and is divided into filled sealed packaging units by the subsequent sealing of the pipe perpendicular to its longitudinal direction below the level of the contents of the tube. Pincushion packaging units are separated from one another by incisions in the transverse suture zones, given a desired, usually parallelepipedal, final form by the end in terms of form and seam-forming operation, during execution they thibaudia two upper triangular double-walled corner tabs which are attached to adjacent the opposite sides of the package, and two lower double-walled triangular corner tabs bend is such parallelepipedon pay package, you can specify the product "Tetra Brik"(R)used for packaging and transportation, among other things, liquid foods such as milk, juice, wine, etc.

Another well-known example of a disposable package of the above type is "Tetra Top"(R), which is also used for packaging and transportation, among other things, liquid foods such as milk, juice, wine, etc. Such a well-known single-use packaging is made from prefabricated blanks of which is made on the basis of paper or cardboard of the packaging material by the original manufacture of the pipe by connecting with each other of two opposite edges of the workpiece with the formation of the longitudinal seam overlap. One of the open ends of the tube (corresponding to the upper part of the package) is closed with a plastic cap, which is manufactured using injection molding on the end of the pipe. The pipe then is filled with contents and sealed by forming the bending of the lower part of the tube for the formation of the bottom wall of the same type as that of the above package.

A set of requirements for disposable packaging is, basically, that they should provide the s easily opened without the use of fixtures, for example scissors, and that it should be possible pouring the contents from the packaging dense and clearly limited jet through the hole in the packaging.

In order to satisfy the requirements of a good opening and emptying, known packaging are usually equipped with an opening device of a particular type, for example, tear line provided on the wall of the package, as described in the patent Sweden 344 725. This opens the device, mainly used in disposable packings of "Tetra Brik", may, as described in the patent Sweden 344 725, contain a perforated tear line, performed on one of the upper corner of the reeds packing, running around the corner of the tongue in the area between the top and line the base corner tabs (corresponding to one side of the top wall of the package). Open the package by pulling and bending up the corner of his tongue downward-attached position from the adjacent wall of the packaging, after which part of the tongue is located on a perforated tear-off feature is captured and comes off completely due to the gap by a perforated tear-off features surrounding it, with the purpose of education trubo the type is simple and easy izgotovim and requires no complicated special equipment for production, but often gives uneven, iscrepancy, ragged edge along the line of separation, which leads to the impossibility to carry out the emptying of the packaging required dense and clearly limited jet. The problem is aggravated by the presence of fibrous material in the support layer along a tear line, which easily absorbs liquids, and after a relatively short time, causes softening of the tubular hole of the tongue and complexity when used with further loss, sometimes to a complete loss in the end, the possibility of evacuation.

Disposable packages of the above type may, however, be made from other known packaging materials, which are completely absent paper and cardboard layers or layers of another absorbent material. For example, EP-A-0 353 496 describes the packaging material free of absorbent fibrous layer, which is sufficiently flexible that they can be formed by bending, for example, packaging material type "Tetra Brik". This packaging material contains reinforcing base layer of plastic, and mixed with them the filler in an amount of from 50 to 80% of the total mass of the base layer. As the plastic material for the base layer predpochtitelney on the basis of polypropylene, such as propylene homopolymer with a melting 10 according to ASTM (of 2.16 kg, 230oC), or a copolymer of ethylene-propylene with an indicator of melting from 0.5 to 5 according to ASTM (of 2.16 kg, 230oC). However, EP 0 353 991 or EP 0 353 496, do not give a single example of how should be easy to open and to allow emptying of the desired dense and clearly limited jet packing of the material described above.

The present invention is the creation of a packing container of the above type that does not cause problems, which occur in known packaging containers.

Another task the creation of a packing container having properties and a good opening and a good emptying, without the use of water absorbent packaging material on a base of paper or paperboard.

These and other objectives and advantages are achieved in accordance with the invention by the fact that the packaging container is made of a packaging material containing a supporting layer of plastic and filler, put in plastic in an amount of from 50 to 80% of the total mass of the base layer, while the line of weakened strength is napolneniem, thus, it is possible to provide such a packaging container of the advantages of opening the device described in the patent Sweden 344 725 with the advantages offered by well-known packaging material corresponding to EP 0 353 991 and EP 0 353 496 so that with the packaging material was easy to work with and easy to open. In particular, it was found that the tear-off edge, formed after tearing along the tear-off features around the loop holes open packaging container according to the invention is very smooth and virtually no irregularities or deficiencies which hamper emptying, which appear in the packaging material on a base of paper or paperboard after tearing. Inherent in the packaging material of the tear resistance is relatively high, but can be significantly reduced if you provide the material of the tear-off below and make tearing off along it, and in this case found that the break can be rather easily implemented with the use of a much smaller tearing effort than is required, for example, when the tearing of the corresponding paper material with a perforated tear-off feature, even if p is I facilitate later separation or tearing of the opening part of the wall of the packaging container according to the invention can be provided with an easily accessible gripping device in the form of a gripping ring or gripping loops, United with part of the wall, which can be a part of it, for separating or removing part of a wall.

In the packaging container of "Tetra Brik" tear-off line may preferably be located around one of the upper triangular corner of the reeds of the container in the area between the center line of the base corner tabs (corresponding to one side of the top wall of the container and the top corner of the tab and tear portion of the wall forming the hole, thus represents an integral part of the tongue next to the tear-off feature towards the top corner of the tongue, which at the same time serves as a gripping device for facilitating the tearing off.

Further preferred embodiments of the packaging container according to the invention.

In Fig. 1 is an isometric image of the upper corner of the tongue of the packaging container according to the invention, equipped with an opening device;

Fig. 2 corresponding to the isometric image of the packaging container according to Fig. 1 after opening;

Fig. 3 a section along III-III in Fig. 1 in an enlarged scale.

Packaging container according to the invention, which is depicted only Vernier BRIC", geometrically performed prismatic shape, has four side walls, pairs opposite to each other, 2 and 3 respectively and essentially flat upper side 4, which is from two opposite edges 5 (of which there is only one) forms a double-walled triangular corner tabs, each of which is connected with and forms a transition between the top side 4 and the respective adjacent side wall 2. The packing container 1 has, in addition, the sealed edge 7 extending from the top 6A of one of the corner reeds 6, to the top of the other (not shown), crossing the upper side 4, which forms facing each other peripheries of the packaging material, welded internal parties in a sealed seam, closing the upper side 4 and the angular tongue 6, respectively. Two upper corner of the tongue 6 of the packaging container with the corresponding extreme areas sealed edges 7 are bent down and attached to the respective side walls 2, so they do not interfere and are protected when handling them during transport, etc.

The packaging container of a known type, shown in Fig. 1 and 2, usually made from a strip of flexible packaging material, etc is the overlap. The fill pipe designed for this content and share the sealed hermetic packaging units by successive transverse sealing of the tube perpendicular to its axis below the level of the contents of the tube. Pincushion packaging units are separated from one another by cutting in the transverse connective areas of the pipe and it becomes desirable parallelepipedal final form through the implementation of the final operations of molding and sealing, during which two upper triangular double-walled corner of the tab package bent down and attached to the adjacent walls of the package, as shown in Fig. 1.

The packaging container 1 according to the invention is made of flexible packing material of the type described in two publications EP 0 353 991 and EP 0 353 496, which is depicted in enlarged 2 times in cross section along III-III in Fig. 3.

The packaging material, thus, contains a hardening supporting layer 8 made of plastic and filler, put in plastic in an amount of from 50 to 80% of the total mass of the base layer. Plastic carrier layer 8 is preferably polyolefin plastic such as polyethylene, polypropylene, etc. simerly such plastics based on polypropylene can be a homopolymer of propylene with an indicator of melting up to 10 according to ASTM (2,16 kg, 230oC) and the copolymer of ethylene and propylene with the rate of melting from 0.5 to 5 according to ASTM (of 2.16 kg, 230oC). Of these two above-mentioned plastics copolymer of ethylene and propylene is the most preferred because it retains the properties of good weldability and mechanical strength at low temperatures, for example, 8oC and below. As filler skeletal layer 8 may be used any known granular and/or flaky filler 7 among such as talc, mica, clay, and T. D. preferably talc. The amount of filler ranges from 50 to 80% of the total mass of skeletal layer, but preferably about 65% by weight.

The thickness of the base layer may vary depending on which molding is subjected to the packaging material by bending, thermoforming or machined in a different way, but generally lies in the range of thickness of 150 to 1400 μm. If the workpiece or strip packaging material should be molded in a package by forming a bend, the supporting layer 8 preferably has a thickness lying in the lower part of the range of thicknesses, for example, 150 to 300 μm, while, if the package is supposed to make pore is positive related to the top of the thickness range, for example, 1000 to 1400 μm. When the packaging material is used for the manufacture of packages of the type shown in Fig. 1 and 2, or packaging other common types for liquid food products, such as milk, juice, wine, etc. supporting layer 8 may have a thickness of about 400 μm, which allows the packaging material be sufficiently flexible that it can easily be formed by bending, and at the same time ensured a sufficient stability of shape of manufactured packaging.

Tear-off line 9 in accordance with the invention may be an incomplete cut or similar linear recess, weakening the material of the base layer 8. Preferably, the incision is performed from one side of the base layer (corresponding to the outer side of the container, as shown in Fig. 3. Needless to say that the degree of anticipated weakening of the material increases with increasing depth of the notch 9, and that therefore, the resistance of the packaging material to the gap decreases with increasing this depth, but in accordance with the invention, surprisingly, it is shown that a sufficient weakening of the material, and accordingly, sufficient low resistance packing m the comrade of the total thickness of the base layer, regardless of whether in which part of the above thickness range of 150 to 1400 μm, bottom, or top, is the thickness of the base layer. More detailed studies showed that the tear line 9 with a depth of incision only 10 to 30% of the total thickness of the base layer 8 provides 60 - 80% reduction of the resistance of the base layer break and consequently good enough weakening the packaging material and packaging container of this material, and the packaging container of this material can be easily opened by tearing along the tear line in the above way. For the base layer thickness of about 400 μm, therefore, it is the depth of incision of about 30 μm. Besides the fact that the packing material is easily broken due to such a tear line, the edge of the gap along the entire contour of the margin around velinova hole 10 is smooth and very good, with no protruding bumps or other imperfections that impede evacuation in case of the normal tearing of the packaging material on a base of paper or paperboard. Since the packing material in the packing container according to the invention is completely devoid of absorbent fibrous layers that there is no danger , with the contents of the container during for example, it is pouring.

To further facilitate the tearing part of the wall forming the hole and the limited tear-off feature, the packaging container 1 can be provided with an easily applicable gripper with which this part of the wall can be easily detached. This gripping device may, for example, be an integral part of the excavated side of the wall, such as angular (reed) plot, or a separate eyelet or ring, you can pull attached to the side wall. In the example shown in Fig. 1, the specified capture device is solid corner (reed) plot outside the tear-off features 9.

As is shown in Fig. 3, the packing material of the packaging container according to Fig. 1 may also have an external connection and/or a protective layer 11, is welded to one of the sides of the base layer 8 to improve the connective properties of the packaging material and/or protection to be carrying layer 8 if necessary. The outer layer 11 may have a thickness of about 5 to 50 m and be of plastic of the same type as the plastic carrier layer 8. The advantage of using the same plastic for the base layer 8 and the outer layer 11 costamesa achieves the effect, production of the packaging material may be effected with the least possible expenditure of material. The packing material also becomes extremely useful from the point of view of environmental protection.

Although the invention is illustrated particularly preferred variants of its performance, for the person skilled in the art it is obvious that the scope of the claims can be implemented in practice many side options, ones like the above implementation, given as an example. For example, the tear-off feature does not necessarily have to be a cut, but can also be made in the form of recesses in the bearing layer, obtained by compression of the material, or plastic deformation, and moreover, if necessary, the tear line can be placed anywhere in the packaging material, in contrast to the presented accommodation around one corner of the reeds packaging. Thus, the tear line may consist of two parallel cuts that are located around the entire packaging container between the top and bottom of the packaging container, with the open part of the wall, in this case, prestley to be limited, or closed part of the wall against which provided that it should be cut off completely, but the tear line may also be, for example, U-shaped notch on, for example, the top package with a part of the wall, with part of the wall forming the hole in the third case represents part of the upper wall of the packaging inside a U-shaped incision, which when opening the packaging must be separated without its complete removal.
