P 9 is made of nylon or half styrene, and the covering layers 2 and 10 of polyethylene are made of plastic of the same composition. 2 hp f-ly, 4 ill.
    The invention relates to the packaging of food liquids.
    The purpose of the invention is to improve the reliability of the package.
    FIG. 1 shows a multi-faceted bag before opening; in fig. 2 - the same after opening; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. 2
    The multi-faceted bag is made of material 1 with an internal coating in the form of a layer 2 of plastic. The triangular protrusions 3 of the bag are bent and attached to the side edges 4. The sealing joint 5 is formed by joining the inner sides of the end sections of the upper face 6 and connects the projections 3. The side lap seam 7 is placed on the side 4 and top 6 faces x before intersection with the sealing joint 5 .
    The device for tearing the sealing gap 5 and forming the drain hole 8 is made in the form of a strip 9 of a non-expanding material. The strip 9 is placed along the area of the sealing seam 5 between the plastic layers 2 of the inner coating of the material 1 of the bag, facing one another. The end portion of the strip 9 protrudes from the sealing seam 5 and is placed on the outer surface of the bag, forming a gripping element. The strip 9 is provided on both sides with a covering layer 10 of plastic of the same composition as the inner layer of the package material. The layers 2 and 10 of the plastic are joined by heat treatment. The strength of this compound exceeds
    joint strength between strip
    9 and covering it with a layer of 10 plastic.
    Preferably the package in which the strip 9 is placed on the area of the sealing seam 5 between the free end of the triangular protrusion. 3 and the intersection point of the sealing 5 and side lap 7 seams.
    It is advisable to perform a strip of 9 of Nylon or polystyrene, and the covering layers 2 and 10 of polyethylene.
    J When used, the bag remains sealed during storage and transport. At the opening, the strip 9 is pulled up. Located on both sides of the strip 9 covering layer 10
    Q and plastic of the same composition as
    the inner material of the bag is separated from the inextensible material of strip 9. Layers 2 and 10 surround the drain hole 8, increasing the strength of the bag 5, since the bond strength of layers 2 and 10 of plastic exceeds the bond strength between strip 9 of inextensible material and covering it a layer of 10 plastic. Due to the placement of the strip 9 in the area of the sealing seam 5 between the free end of the triangular protrusion 3 and the intersection point of the sealing 5 and side lap 7 seams, the drain hole 8 has limited dimensions, which also increases the strength of the package. The condition of the superior strength of the connection between the covering layers 2 and 10 of the bond strength of the layers

    Claims (3)
    [1]
    10coat with strip 9 is observed 3 when making strip 9 of nylon or polystyrene, and covering layer 2 and 0 of polyethylene. Claim 1. A multi-faceted bag made of a material with an internal plastic coating containing triangular protrusions, bent and attached to the side edges, a sealing seam connecting the projections and formed by the connection of the inner sides of the end sections of the upper edge, side lap lap, placed on the side and top face to the intersection with the sealing seam, and a device for breaking the seam and forming a drain hole, made in the form of a strip of non-expanding material, along the area of the sealing seam between the layers of the package material, facing one another with inner coatings, the end portion of the strip protrudes from the sealing seam 55 and is placed on the outer surface of the package, forming a gripping element the fact that, in order to improve package reliability, the strip is provided on both sides with a plastic coating layer of the same composition as the internal coating of the package material, which is connected to the latter by means of thermal sealing, and the strength specified The joint strength exceeds the strength of the joint between the strip and the plastic layer covering it.
