专利说明:

The invention relates to packaging, in particular to cardboard containers coated with thermoplastic having means for opening it.
The goal is to prevent damage to the package.
Figure 1 shows the lid of the closed package with a device for tearing, top view; Fig 2 - the same, partial section (along line A - A) on an enlarged scale; Fig 3 - the same, from the inside of the package (in the right corner the view is incomplete); 4 is the same as another modification; figure 5 is the same. which is in FIG. 3, but for another modification close to FIG. 4.
All packaging modifications shown in the drawings are for liquids. The package is provided with a lid 1 which is made of carrier material 2, such as cardboard or paper, which is provided with a plastic coating 3 on the outside and a plastic coating 4 on the inside packaging side.
In the lid 1, a slot 5 is provided in which the tearing device is installed.
A perforation line 6 is made on the lid. Along the perforation line 6, which in this case is a closed oval line, there is a tear-shaped device 7 in the form of a rivet (according to the modification of FIGS. 2 and 3, with a ring 8 attached to the outer surface gripping ring 9). The tear device is made of plastic by means of injection molding and has at least one annular radial groove 10, tightly covering the edge of the slot.
Using a perforation line 6, a drain hole is formed, which corresponds to the tear-off part 11 of the lid (within the line) 6 perforations). The edge of the tearing device 7 on the side of the inner surface of the cover is adjacent to the perforation line 6 in at least one place.
In the modification of FIGS. 2 and 3, the rivet-shaped device 7 for tearing is at the point closest to the side edge 12 of the lid and forming the top of the drain hole.

This is formed practically round, shown in FIG. 3 by a dashed line slot 5. It is located, like the riveted rifle device 7, within the perforation line B, i.e. in the detachable part of the cover. The preformed ring 8, according to FIG. 2, is placed on the upper plastic layer of the lid 1. The lower outer edge 13 of the ring 8 is located coaxially with the perforation line 6 (in FIG. 2 to the right). In addition, the ring 8 has an outwardly open and radially in relation to the drain hole outside the groove 14, which runs annularly along the edge and serves to re-close the outlet. The thickness of the groove 14 (Fig. 2, right) is greater than that of the paper layer, including the plastic layers. On the underside of the ring 8 and on the opposite ring, the rivet-shaped device 7 for tearing has a wedge-shaped bevel 15 for improved re-closure.
In FIG. 3, the lid is visible from the inside of the package, which makes it possible to determine the outer contour of the rivet-shaped device 7 for tearing along an extended line in the shape of a circle.
The modifications of FIGS. 4 and 5 also include a section of the ring 8 in the form of a rivet, but not along the entire perforation line 6, next to which, as a rule, a longitudinal slot is provided throughout. In Fig. 5, the longitudinal slot is partially present, but it is interrupted in four places, where the EIDND is a dash-dotted line 6 of the perforation. Fig. 5, like Fig. 3, is a view of the lid from the inside of the package in a still closed state. In Fig. 5, in the second modification, a mushroom-shaped thickening of the rivet-shaped tearing device 7, looking inside the package, is seen on two parallel oval solid lines, which is connected to the upper ring 8 only through longitudinal slots.
The slot of the cover is made in the form of a discontinuous ring.
The described tear device allows easy opening of the package exactly along the perforation line, as well as re-closing the package due to the presence of radial grooves.
