The invention relates to opakovat, for example, soft drinks and milk, are manufactured in such a way that from a roll of packaging material receive, for example, Kirpichenko form.

In Fig. 1 shows a view in cross section of a conventional packaging material.

As shown in this drawing, the packaging material 11 consists of a paper base 13, the layer 14, which is an inner layer, when the packaging material 11 is converted into a packing container (hereinafter simply referred to as "inner layer"), layer 15, which is an outer layer, when the packaging material 11 is converted into a packing container (hereinafter simply referred to as "outer layer"), gasosaurus layer 16 formed between the paper base 13 and the inner layer 14 and adhesive layer 27. Paper base 13 is made of cardboard or similar material and gasosaurus layer 16 is fastened to it through the adhesive layer 27.

The opposite side edges of the packaging material 11 overlap each other, and then connected to each other in the longitudinal direction by means of thermal fusion, in order to receive the tubular packaging material. Thereafter, the tubular packaging is here. Then the tubular material is squeezed from both sides and sealed in the transverse direction at set intervals in order to receive a container in the form of pillows, which is then converted into Kirpichenko form.

The tape 25 is attached to the sealed area, running in the longitudinal direction along the inner surface of each of the packaging container (hereinafter referred to as "longitudinal section of the sealing"), in order to prevent the flow of air in the packaging container from a side edge of the packaging material 11 and to prevent seepage of liquid food product through a paper basis 13.

Packaging containers, in which the inner layer 14 of the packaging material 11 made of a polyolefin resin, do not have sufficient storage capacity palatability of food. This is because the liquid food contained in the container, in contact with the polyolefin resin, which is all the time absorbs liquid flavoring ingredients of food.

In order to increase the capacity of each container to preserve the taste, the layer of the polyolefin resin may be covered with N. is this case, the tape 25 is made of poliolefinas resin, which can be easily connected with the above resin, ensuring the preservation of taste, by means of thermal fusion. The tape 25 is attached to the longitudinal section of the sealing using heat and pressure.

If the inner layer 14 rulonoboev packaging material made of resin, ensuring the preservation of taste properties, the resin is connected with the polyolefin resin forming the outer layer 15, when the overlapping side edges of the packaging material 11 are melted and connected in the longitudinal direction. However, since resin, ensuring the preservation of taste, and polyolefin resin hardly are connected to each other, can be obtained only weak sealing.

This problem can be solved by connecting resin, ensuring the preservation of taste, and polyolefin resin by melting after activation of the sealing part of the surface of the resin, ensuring the preservation of taste, by corona treatment, treatment with ozone or processing by a flame or by combining resin, providing the SS="ptx2">

However, sufficient sealing cannot be obtained even if the resin, ensuring the preservation of taste, is subjected to corona discharge, ozone treatment or processing of flame.

When the resin, ensuring the preservation of taste, and polyolefin resin melt at a high temperature for their connections with each other, the manufacturing costs increase due to the necessary use of the device for high-temperature melting.

You can connect the resin, ensuring the preservation of taste and forming the inner layer 14, and the polyolefin resin forming the outer layer 15, an adhesive composition made from a copolymer of ethylene and vinyl acetate (EVA), chloride, polyethylene and the like. However, in this case additionally the stage of application to the packaging material 11 of the adhesive composition and drying, which increases the complexity and cost of the manufacturing process and complicates the work.

The technical result of the present invention is to solve the above problems inherent in conventional packaging containers, and the creation of a packing container, which has einer according to one aspect of the present invention includes a packaging material, the outer strip and the tape. The opposite side edges of the packaging material overlap each other, so that the outer layer and the inner layer of this packaging material were facing each other. Outer band is inserted between the outer layer and inner layer along the longitudinal section of the sealing and connected by means of thermal fusion with the outer layer and inner layer. Outer band has an outer layer and an inner layer. The ribbon is located on the inner surface of the packaging container along the longitudinal section of the sealing and attached to it by means of thermal fusion.

The inner layer of the packaging material and the outer layer of the outer strips are made from resins that are compatible with each other, while the outer layer of the packaging material and the inner layer of the outer strips are also made from resins that are compatible with each other.

In the event of such patterns resins which are compatible with each other, are melted and connected to each other for forming a longitudinal sealing portion, thus providing an amplified effect sealing.

Packaging container according to another aspect of the outer layer and inner layer. The opposite side Kratki packaging material overlap each other, so that the outer and inner layers of the packaging material facing each other.

The intermediate layer and the inner layer of the packaging material protrude from the side edges of the paper base and the outer layer for forming a curving portion that runs along the area of sealing. Curving part is inserted between the outer layer and inner layer of the packaging material by means of its bend and is connected to these layers by thermal melting.

The outer layer and the intermediate layer of the packaging material are made from resins that are compatible with each other. In the event of such patterns resins which are compatible with each other, are melted and connected to each other for forming longitudinal section of the sealing, thus providing an amplified effect heat sealing.

The side edge of the packaging material located on the inner side of the packaging container, covered with a turned back portion. Accordingly prevents the transmission of liquid food product paper through the edge of the packaging material, therefore, nty to the inner surface of the packaging container along the longitudinal section of the sealing.

Packaging container according to another aspect of the present invention includes a packaging material, the layer of molten when heated, and tape. The opposite side edges of the packaging material overlap each other, so that the outer layer and the inner layer of the packaging material facing each other. Layer, melting when heated, is located between the outer layer and inner layer along the longitudinal sealing part. The ribbon is located on the inner surface of the packaging container along an area of the sealing and attached by means of thermal fusion.

Under such a structure reinforced the effect of sealing can be obtained due to the presence of the layer of molten when heated and located between the inner and outer layers.

In the packaging container according to another aspect of the present invention the inner layer of the packaging material is preferably from neolatinos resin, ensuring the preservation taste.

In this case, since the liquid esophagus product in the packaging container is in contact with the resin, ensuring the preservation of taste, flavoring ingredients liquid p is equipment, to the outer side of the paper base was formed of heat-absorbing layer.

In this case, the outer surface of the paper base is covered with a heat-absorbing layer along the longitudinal sealing part. Accordingly, when the emission of infrared rays to the longitudinal sealing part, a heat absorbing layer due to heat generated by the radiation, is subjected to local heating, the intermediate layer and the outer layer can be easily melted and connected to each other without changing the color on the rest of the printed surface.

Design and distinctive packaging containers according to the present invention will be clear if you refer to the accompanying drawings, on which:

in Fig. 1 shows a view in cross section of a conventional packaging material;

in Fig. 2 shows a view in cross section of the packaging material according to the first variant implementation of the present invention;

in Fig. 3 shows a view in cross section of the packaging material according to the second variant of implementation of the present invention;

in Fig. 4 shows a view in cross section of the packaging material according to the third variant of implementation nastoya variants of the present invention.

In Fig. 2 shows a view in cross section of the packaging material according to the first variant implementation of the present invention.

As shown in Fig. 2, the packaging material 11 consists of a paper base 13, the inner layer 14, the outer layer 15, gasosaurus layer 16 formed between the paper base 13 and the inner layer 14 and adhesive layer 27. The paper base 13 made of cardboard or the like, in gasosaurus layer 16 is glued to the paper base 13 by means of adhesive layer 27. For formation of adhesive layer 27 is used a copolymer of ethylene and acrylic acid or something like that. For education vasopeptidase layer 16 of aluminum foil.

The inner layer 14 is formed of resin, ensuring the preservation of taste and deposited on the surface gasosaurus layer 16, however, he will be placed on the inside of gasosaurus layer 16, when the packaging material 11 is formed in the packing container. The outer layer 15 is formed from a polyolefin resin, which is deposited on the surface of the paper base 13, it will be located on the outside of the paper base 13 when the packaging material 11 forms and gasosaurus layer 16.

Examples of resins that ensure the preservation of taste, include polifenole resin such as polyester resin, polyamide resin, polyvinylidenechloride resins, ethylene vinyl alcohol copolymers, polyvinyl chloride resins, epoxy resins, polyurethane resins, polyacrylate resins, polyacrylonitrile resin and polycarbonate resin. Molten resin, ensuring the preservation of taste, is forced out of the extruder, not shown, in the form of a film and then applied to the inner surface gasosaurus layer 16. A small amount of additives, such as nitrocellulose, can be added, but not necessarily, in the molten resin, ensuring the preservation of taste. In the present example, as the resin, ensuring the preservation of taste, used a modified polyester.

Because liquid food product comes in contact with the resin, ensuring the preservation of taste, flavoring ingredients liquid food product is not absorbed by it. The result can be achieved by increased persistence taste.

Examples of polyolefin chips include polyethylene, is the quality of the polyolefin resin is polyethylene.

Packaging container for storing liquid food product can be obtained by converting a roll of the packaging material 11, for example, in Kirpichenko form. More precisely, the opposite side edges of the packaging material 11 overlap each other and are interconnected by means of thermal fusion in the longitudinal direction so as to receive the tubular packaging material. The obtained tubular material continuously moves down, while it served on top of a liquid food product. Then the tubular material is squeezed from both sides and sealed in the transverse melting at set intervals in order to obtain pincushion containers, which are then converted into Kirpichenko form.

Because the inner layer 14 made of resin, ensuring the preservation of taste, it is difficult to connect the inner layer 14 and outer layer 15 by means of thermal fusion, in order to join the opposite side edges of the packaging material 11 in the longitudinal direction. Also it becomes difficult to combine by means of thermal fusion opposite the inner surface SL is tvline his designs use the outer band 20, which is located between the inner layer 14 and outer layer 15 along the longitudinal section of the seal in order to prevent direct contact of the outer layer 15 and the inner layer 14. Therefore, the opposite side edges of the packaging material 11 are connected to each other through the outer strip 20.

With this purpose, the outer band 20 is attached to the packaging material 11 along the longitudinal section of the sealing before the packaging material is sterilized using hydrogen peroxide. In this case, the longitudinal section of the sealing of the outer layer 15 are directed infrared rays or streams of hot air.

Outer band 20 consists of an inner layer 21, which is in contact with the outer layer 15 made of resin that is compatible with the outer layer 15, the outer layer 23, which is in contact with the inner layer 14 made of resin that is compatible with the inner layer 14 and adhesive layer 22 for connection is made from the resin of the inner layer 21 and the outer layer 23.

The inner layer 21 is made of polyolefin resin. Examples of the polyolefin resin include polyethylene, polypropylene, low density polyethylene and Lina is flax low density.

The outer layer 23 is made of neolatinos resin. Winners neolatinos resin include polyester resins, polyamide resins, polyvinylidenechloride resins, copolymers of ethylene - vinyl alcohol, polyvinyl chloride resins, epoxy resins, polyurethane resins, polyacrylate resins, polyacrylate resins, and polycarbonate resins. In the present embodiment, the design used a modified polyester.

As described above, the effect of sealing can be improved by placing the outer strip 20 between inner layer 14 and outer layer 15 along the longitudinal section of the sealing.

Since the packaging material 11 has rulonoboev form, the paper base 13 at the side edges of the packaging container is exposed to liquid food product. Therefore, the tape 25 is attached to the inner surface of the packaging container along the longitudinal section of the seal in order to prevent the exposure of a paper base 13 of the liquid food product.

The tape 25 is composed of a layer of modified polyester, adhesive layer, a layer of extruded polyester, adhesive layer and a layer of codified polyester, which Navigator designed to strengthen the tape 25.

Next will be described the results of tests that were conducted on packaging containers manufactured by the method described above.

When carrying out tests on artificial load to the packing containers were applied load of 50 kgf. When testing for the detection of pores pores are not detected in any of the 1000 surveyed packaging containers. Were then performed tests on the resistance drop by drop 50 packaging containers with a height of 270 see None of the containers were found not to have leaks liquid food product.

In addition, there were vibration tested by application to each packing container vibration of about 12 Hz for 30 minutes, it was also applied load of 0.5 g. In 891 tested packaging containers were not detected pores leakage of liquid food product. The upper part of one of the packing containers had been deformed.

Below will be described a second variant implementation of the design of the present invention.

In Fig. 3 shows a view in cross section of the packaging material according to the second variant implementation of nastoyasheye base layer, the inner layer 14, the outer layer 15, gasosaurus layer 16 formed between the paper base 13 and the inner layer 14 and adhesive layer 27 in the form of an intermediate layer. The paper base 13 made of cardboard or the like, and gasosaurus layer 16 is glued to the paper base 13 by means of adhesive layer 27. For formation of adhesive layer 27 is used resin that is compatible with the outer layer 15. For the formation of gasosaurus layer 16 of aluminum foil.

The inner layers 14 forms the resin, ensuring the preservation of taste, which is applied on the inner surface of vasopeptidase layer 16, the Outer layer 15 is formed from a polyolefin resin, which is applied to the outer surface of the paper base 13.

Examples of resins that ensure the preservation of taste, include polifenole resin such as polyester resin, polyamide resin, polyvinylidenechloride resins, copolymers of ethylene - vinyl alcohol, polyvinyl chloride resins, epoxy resins, polyurethane resins, polyacrylate resins, polyacrylonitrile resin and polycarbonate resin. Molten resin, ensuring the preservation taste cunosti vasopeptidase layer 16. In the molten resin can be added, but not necessarily, a small amount of additives, such as nitrocellulose. In the present embodiment, design as resin, ensuring the preservation of taste, used polyester.

Because liquid food product comes in contact with the resin, ensuring the preservation of taste, taste the caustic ingredients of the food product it is not absorbed. This results in increased sohranyaemostyu taste.

Examples of the polyolefin resin include polyethylene, polypropylene, polyethylene, low density linear polyethylene with a low density. In the present example, as the polyolefin resin used polyethylene. Therefore, polyethylene is also used for the adhesive layer 27.

Packaging container for liquid content of the food product can be obtained by converting rulonoboev of the packaging material 11, for example, in the form of a brick. More precisely, the opposite side edges of the packaging material 11 overlap each other and are joined by thermal fusion in the longitudinal direction for policema as liquid food product is fed into it from above. Then the tubular material is squeezed from both sides and sealed in the transverse direction at set intervals to obtain containers pincushion shape, which is then converted to Kirpichenko form.

Because the inner layer 14 is made of resin, ensuring the preservation of taste, it is difficult to connect the inner layer 14 and outer layer 15 through the heat of melting for connecting the opposite side edges of the packaging material 11 in the longitudinal direction. Also becomes difficult to melt and connect the front surface of the inner layer 14.

To solve these problems in the packaging container according to the variant embodiment of the invention uses a design in which the turned back portion 19, as a whole exhaust from the packaging material 11 is located between the inner layer 14 and outer layer 15 in the longitudinal section of the seal in order to prevent the occurrence of the outer layer 15 in direct contact with the inner layer 14. The opposite side edges of the packaging material 11 are connected via the turned back portion 19.

Unbend the Loya 27 with one side edge of the packaging material 11, so they advocate an end surface of the paper base 13 and the outer layer 15 by a specified amount. Therefore, the turned back portion 19 has a layered structure formed by the inner layer 14, vasopeptidase layer 16 and adhesive layer.

Before the packaging material 11 is sterilized by the hydrogen peroxide, the turned back portion 19 is bent outward and formed, and the adhesive layer 27 and the outer layer 15 are in contact with each other and melt with the purpose of their connection with each other. In this case, the black ink 31 serving as a heat absorbing layer is applied on the outer surface of the paper base 13 along the longitudinal section of the sealing. Accordingly, when the emission of infrared rays to the longitudinal sealing part is provided by the local heating of the black ink 31 to a high temperature due to radiated heat, while the adhesive layer 27 and the outer layer 15 can be easily melted and connected to each other without changing the color of the rest of the printed surface.

After that both side edges of the packaging material 11 are melted and joined to each other in the longitudinal direction. Pascalcase 19, one side end part of the inner layer 14 is in contact with the other side end part of the inner layer 14, which can be achieved enhanced sealing.

As described above, the effect of sealing can be improved through the introduction of the turned back portion 19 of the packaging container between the inner layer 14 and outer layer 15 along the longitudinal section of the sealing.

Since the packaging material 11 has rulonoboev form, the paper base 13 is exposed at the side edges of the packaging container to effect a liquid food product. In the present embodiment of the invention the paper base 13 is protected from exposure to liquid food product by coating the side edges exposed, turned back part 19. Accordingly there is no need for bonding tape to the inner surface of the packaging container along the longitudinal section of the sealing. In the result, it is possible to simplify the manufacturing process and reduce costs.

Below will be described a third option to the implementation of the design according to the invention.

In Fig. 4 shows a view in cross section of the packaging materiality material 11 consists of a paper base 13, the inner layer 14, the outer layer 15, gasosaurus layer 16 formed between the paper base 13 and the inner layer 14 and adhesive layer 27. The paper base 13 made of cardboard or the like, and gasosaurus layer 16 is glued to a paper substrate 13 via the adhesive layer 27. For formation of adhesive layer 27 using a copolymer of ethylene and acrylic acid or something like that. As gasosaurus layer 16 using aluminum foil.

The inner layer 14 is formed of resin, ensuring the preservation of taste, which is applied on the inner surface of gasosaurus layer 16. The outer layer 15 is formed from a polyolefin resin, which is applied to the outer surface of the paper base 13.

In the present embodiment, the design of melting when heated layer 30 is located between the inner layer 14 and outer layer 15 along the longitudinal section of the seal. Therefore, both side edges of the packaging material 11 are connected to each other through layer 30, a fusing when heated.
