    Packing containers of the non-returnable type for the packaging of milk, etc, frequently have a fould-out pouring spout which is intended to facilitate the pouring out of the milk in a concentrated jet. However, the air which must enter the packate via the pouring spout at the same time as the pouring outtakes place causes the flow to stop periodically so that the pouring out occurs jerkily. This disadvantage is overcome in accordance with the invention in that the spout is designed to have an emptying duct (7) as well as an air duct (8). The air duct extends into the packing container over such a length that air can pass unhindered into the packing container without disturbing the flow of the contents through the pouring spout.

    This invention relates to packaging containers for liquids. Packing containers are known, which are a body of elastic material, in the upper part of which two opposite sides are connected to form a valve with a sealing rib, a discharge chute and air ducts II and 2 A disadvantage of the known packaging containers is their complexity due to the presence of additional structural elements, closing the air channel. The purpose of the invention is to control the design of the packaging container. This goal is achieved by the fact that, in a packaging container, it is a body made of elastic material, in the upper part of which two opposite sides are connected, forming a valve with a sealing rib, a drain chute and an air channel, an air channel is formed inside the sealing rib and is located along the latter so that its outlet opening is in the zone of the discharge chute. In addition, the drainage chute is separated from the body by a bend line. In this case, the sealing edge includes two lines of connection, which are parallel to the sealing edge at a distance of one from another, and the air channel is the space formed between them with one line of connection pro; walks along the entire length of the sealing edge, and the length of the other line facing the inside of the container is less than the length of the specified line. There is a bend line between the joining lines. Inside the sealing rib between the two sides there is a hollow elastic element forming an air channel. The wall of the air channel has an opening through which it communicates with the internal cavity of the container. The rim of the hole is bent in the direction of the air channel. In addition, the wall has several openings located at a distance from one another. Fig, 1 shows a packaging container, axonometrics; Figure 2 is the same in the open state; FIG. 3 shows a part of a packaging container with a flap bent up; FIG. 4 is the same, with a hole in the air duct, .. The packaging container is a body 1 of elastic material, in the upper part of which two opposite sides 2 and 3 are connected to form a valve 4 with a sealing, edge 5, drainage chute 6 and an air channel 7 formed inside the sealing rib 5, the air channel 7 being located along the latter so that its outlet opening. 8 is located in the zone of the discharge chute 6.
    Drain gutter 6 is separated from the building 1 by line 9 of the bend. The sealing rib 5 includes two lines 10 and 11 of the connection, parallel to the second edge of the edge of 5 and distance from one another, and the air channel 7 is the space formed between the lines 10 and 11 of the connection, and the line 10 of the connection runs across, the line of the sealing rib 5, and the line of the joint line 11 is less than the length of the joint line 10, whereby the air passage 7 ends inside the packaging container, somewhere in the middle of the sealing ebra 5, the joint line 11 has a length approximately twice as long as b ivnogo trough, whereby provided a large space for accommodating the rear end of the air passage 7 in communication with the interior of the housing 1.
    Between lines 10 and 11 of the joint there is a bend line 12, which is formed before sealing the sealing rib 5 by pressing the tool into the packaging material from the inside, i.e. from the sides of the layers of packaging material, about being dragged to each other. In this way, the layers of the packaging material will be arranged with the concave side facing the anti-adhesive layer of the material sealing the double rib, whereby the two layers of material are on a certain distance from each other.
    I go through lines 10 and 11 of the compound, free space remains for
    Formation of an active air channel 7 that passes between the drain chute b and the internal cavity of the container. Line 12 of the bend extends essentially parallel to the two lines 10 and 11 of the joint and in the middle between them, and then it passes at an angle towards the internal cavity of the container, i.e. it follows the direction of the active part of the air channel 7.
    In order for the air channel If located in the sealing edge .5, to take the necessary) form,
    when the valve 4 is bent upwards and the container is opened, even after prolonged storage it is necessary to perform an air kanbsh 7 from an elastic element (not shown) g
    The inside of the sealing rib 5, which is adapted to separate the material layers, as a result of which the air channel 7 takes on the necessary cross section and shape. Said elastic element may be, for example,,:
    from a double-walled poloskn elastic plastic material, of a type that even after a long period tends to regain its original shape. You can also enter into the sealing rib elastic tube or similar element. Valve 4 has a weakened strength line 13, which serves to open the container. In another embodiment of the container, the joint line 11 runs along the entire length of the sealing of the rib 5 and, similarly to the joint line 10, crosses the line 13 of weakened strength. The joint line 11 is located on the opposite side of the sealing rib 5 with respect to the joint line 10, as a result of which, between the joint lines 10 and 11, a relatively wide unfinished area of the saddle rib 5 is formed.
    an air channel 7, which extends between two layers of packaging material opposite each other and forming a sealing rib 5, and is bounded on one side by a connection line 10, and on the other by a connection line 11. Thus, the formed air channel extends across the entire width of the packaging container and has an opening 14 through which the channel communicates with the interior of the container body.
    Hole 14 is preferably located where the drainage chute passes over the packaging container itself. This arrangement ensures that air can flow into the packaging container unhindered through the air duct 7
    and an opening 14 when the container is inclined to discharge the contents through the outlet opening 8, since the opening 14 will then be located above or near the free surface of the contents.
    Due to the fact that the 11cc line 11 runs along the entire length of the sealing edge or across the entire width of the container, the problem of stress concentration and the probability of splitting is eliminated, since the molding forces are distributed along the entire length of the connection line 11. The slight concentration of stresses, which may still occur due to a rupture for the air hole; 14 in the connection line 11, is reduced due to the fact that the edges of the hole 14 are bent in the direction of the air channel 7.
    Since the location of the hole 14 in most cases is not critical for the operation of the air channel 7, the location of this hole can be changed within relatively wide limits. So,
