    A parallelepipedic packing container is manufactured by the transverse sealing of a packing material tube filled with contents. On sealing and subsequent forming of the package, on one hand, sealing fins (11,12) extending over the end walls (4) of the packing container, on the other hand triangular corner lugs (3) located on the short sides of the end walls (4, 5) are obtained. The sealing fins (11, 12) as well as the corner lugs (3) are folded down during the forming so as to lie against adjoining container walls (4, 5). The folding up of the fin (11) as well as the subsequent tearing up are facilitated in accordance with the invention in that one of the fins (11) is given a greater width at the end where the tearing indication (10) is situated. At the same time the opposite end of the fin is made narrower so as to facilitate the folding down of the triangular corner lug (3) located underneath the fin end.

    专利说明:

    The invention relates to packaging. A known package for liquids, comprising walls, forming a valve in the upper part with a sealing rib and a welded seam dividing it into two sections with beveled front sides, one of which has a weakened strength line. A non-returnable type packaging, such as for milk, is made of a flexible laminate having a carrier layer of paper, coated on both sides with thin layers of waterproof, heat-sealing plastic material, such as polyethylene. In production, the packaging material is first attached to a tubular form by soldering along the longitudinal edges, after which the pipe is filled with contents and divided into separate packaging containers by repeated folding and soldering in transverse zones located at a distance from each other. When soldering, the tube is molded to give a parallelepiped shape with a packaging container. After molding, the individual packaging containers are separated from each other by cutting in the adhesion zones. Finished packages have two flattened sealing ribs located on opposite end walls, as well as on double-wall triangular valves attached to these walls. In order not to disrupt the parallelepiped shape, the commissural fins, as well as the collapsed corner valves are bent to the adjacent packing surfaces. . For these triangular double-wall valves and for the sealing rib, different types of perforations for tearing are provided, with which you can make a hole for pouring out of the package. The sealing rib has a comparative narrow weld seam located in the longitudinal direction in which the layers of material entering the sealing rib are connected to each other. This seam is located at a distance from the base line of the rib, and the separation perforation is thus located in the rib region, where the layers forming it are not connected to each other. An indication of the separation point, consisting of a perforation line that penetrates the carrier layer of the packaging material, but not its waterproof layers, comes from one end of the sealing rib (or the tip of the adjacent triangular valve). In a package, the width of the commissure rib is significantly greater than the width required for molding or sealing. This is done so that after bending the rib, I can but I could take it with my thumb and forefinger and begin, thus, tearing it off and continue it along the perforation fl. However, in order to prepare the edge for opening, it must be bent. With this, the rear end of the sealing rib, like the end located at the location of the breakaway indication, protrudes above the flattened angle valve, which is bent down to one side wall of the package. When only one of the corner legs is folded over and the end of one sealing edge is lifted, the outer free edge must be pulled out, which is impossible due to the low elasticity of the material. This can be achieved if the angle valve, bent down at the opposite, or at the rear, end of the sealing rib is also bent up, resulting in a sealing rib lifting along the entire length. However, this leads to a significant weakening of the upper part of the package, as a result of which it is easily deformed, since it is gripped with one hand while pouring the contents. In addition, the wide sealing rib makes it difficult to bend down the angle valve, located at the rear end of the rib, to the side of the package. A badly bent angle valve hinders the use of the package and increases the possibility of deformation. The purpose of the invention is to improve the usability of the package. The goal is achieved by the fact that in a package for liquids, including walls, forming a valve in the upper part with a sealing rib and a welded seam, dividing it into two sections with beveled front cTOt rons, one of which has a weakened strength line, the valve edge is at an angle to the weld seam of the package so that the end portion of the valve section between the weld and the edge, opposite the side with the line of weakened strength, has a width 2-6 times smaller than the opposite side of the ana. FIG. Figure 1 shows the layout of the packaging for liquids; in fig. 2 - packaging for liquids in isometry; in fig. 3 - the same in the open position. After the tissue-like packaging material is transformed into pipe 1, in the process of moving down through the machine (not shown), the edges of the packaging material are brazed along the joint (not shown) located along the pipe. The packaging material tube is then filled with contents and flattened in successive transverse zones 2. At the same time, the portions of the tube 1 located between them are formed by forming devices (not shown), so that a rectangular cross section is obtained. Triangular two-wall valves 3, bordering flattened zones 2, as well as side and front, walls 4 and 5 of the packaging, respectively, adjoin the flattened areas. In each of the flattened areas 2, the stack of packaging material pipe joins each other with such force that the contents, located in the tube is displaced until the inner plastic layers of the packaging material lie flat against each other. As a result of the activation of the heating elements on the solder clamps (not shown), the indicated thermoplastic layers are welded with two welds 6 and 7, replaced along the flattened zone. The welds are located parallel to the zone, flattening at some distance from each other and adjacent to the base lines 8, separating the flattening zone 2 from adjacent end walls. In the packaging material web, a weakened strength line 9 (tear perforation) is created in advance and during the process receiving the packaging from the web is guided in such a way that it appears in the flattening zone 2 near the base line 8, especially between the insulating line 9 and the weld seam 7 bordering it at one end of the flattening zone 2. In a tactilely folded package, a cut is made in the packaging material in the flattening zone 2 in region 10 between two welds b and 7 with several oblique relative to the longitudinal direction of the flattening zone, with the result that one end of the cut touches one end of the weld 6 and the opposite - the opposite end of the weld seam 7. Consequently, the flattening zone 2 is divided respectively into two sealing ribs 11 and 12; each having a wide and narrow end. The sealing rib 11, which is then located on the upper end of the finished package, is oriented in such a way that its width is maximum at the end of the rib, where the tear-off point is located. The free edges of the sealing ribs 11 and 12 are located at right angles from the wide to narrow end of the sealing ribs, the edge of which is adjacent to one end of the weld 7. The sealing rib I I 12, which is then located on the bottom of the package, is made the same thus, except that it narrows in the opposite direction. .. The sealing rib 11, located on the upper end of the package, bends downward to its end wall 4 and is placed both on the end wall and on triangular valves 3, which are also bent downwards to the side wall 5 of the package. The weakened strength line (tear-off perforation) is located in the sealing rib 11 between the base line 8 and the weld seam 7. The tear-off point 9 is indicated from the wide end of the sealing rib, i.e. end, which coincides with the free angle of the triangular valve 3, along part of the rib 11 located on the triangular valve 3, further up to the part of the rib located on the wall 4 of the package, and ends at point 13 on the central part of the end wall 4 of the package (at some distance from the longitudinal spa 14). The length of the weakened strength line (tearing point) is twice the length of the part of the sealing rib 11 located on the triangular valve 3, which allows the neck 15 (Fig. 3) to be formed with a relatively large opening after the break at the direction of the break point 9. To facilitate the formation of the neck 15 on the package opening, there are lines of 16 folds on the upper end wall, along which parts of the package forming the neck can be easily folded. The end point 13 of the line of weakened strength (tearing perforations 10) should be located near the intersection point of lines 15 fold. The rib 12 located in the lower part of the package, like the valves, is bent to its lower wall and therefore in FIG. 2 and 3 it is not visible. FIG. 3 shows the process of opening the package: a triangular flap 3 bent to the side wall 5 of the package is folded up, after which the wide end of the sealing rib 11 is also bent upward at a right angle to the upper end wall 4 of the package. Then the wide end of the sealing rib 11 captures the mezkda with the thumb and forefinger and the tearing of the giot along the line - labeled strength (perforation tear 9). A hole is formed, which can be expanded into a rhombic configuration, while this valve -3 is bent up slightly and. at the same time, parts of the package, q, 6pa3ykie throats of BJO, flexion from the lines of 15 folds. This construction ensures a stable neck with a large opening, which makes it much easier to drink the contents. The end part of the valve section between the weld and the edge, opposite the line with the weakened strength line, has a width that is smaller than the width of the opposite end face of the valve. Consequently, bending up pyrokogo KONIGD epopevtstsotsogo 11 I9 ribs on the hunt, shown on fng. 2, in a position under the front corner to the upper end wall 4, is much easier, since the part behind the printing rib, which runs along the opposite corner of the valve of the end wall, is relatively narrow and has little resistance to bending the wide end of the sealing rib. This is due to the fact that the free end of the sealing rib (FIG. 2), when it passes along the rear boundary line of the upper end wall 4, is located very close to the base line 9. When the front end of the sealing ribs is bent upwards, the bout does not significantly extend in the direction of the free edge 17. When the package is opened further, tearing of the tear-off perforation O (line of weakened strength) is lightweight due to the fact that the wide end of the sealing rib is 2-6 times wider than between the weld seam 7 and the base line 8 at the other end, which provides a large space for the fingers. The advantage of the proposed package is that the obliquely cut off edge indicates which end to open the packaging container, and at the same time makes it impossible to open it from the other end, because the adhesive edge there is so narrow that any attempt to open the packaging container unsuccessful. In addition, the proposed packaging is easier to use and easier to open than is known, eliminates the increase in the need for material dp from its preparation and a significant restructuring of the existing equipment, which ensures its high competitiveness.
