DE2001093A1 - Opening device on packaging - Google Patents

Description

The present invention applies to an opening device on a package, which consists of a sealed at its ends, preferably a parallelepiped-shaped tube with double-walled triangular fields created by the closure, which protrude from the ends of the packaging and are bent in towards the side walls, with one of the fields bent out and to form part of the opening device, and on the inside of the last-mentioned triangular field to cover an opening in the triangular field, a closure strip is attached to the one free edge of the triangular field is bent over and over the outside of the field and the end wall the packaging continues to run,

Square packaging of this type is used for both powdery and granular contents as well as liquids, such as milk, Used · Various types of opening devices have been proposed for such packaging, and these Proposals have usually aimed at bringing about an opening device that is easy to open by the consumer is open. The opening device according to the invention fulfills the same purpose, but above all wants to be light Combining opening with the possibility of removing the product from the packaging in a well-collected, straight forward jet to be able to pour, through an opening device, which is just as easy to manufacture as many previously proposed opening devices.

For this purpose the opening device is according to the invention characterized in that the pouring opening consists of a slot present in the end wall of the packaging consists, which is in the outer wall of the mentioned one double-walled box extends, and that in the said a free edge of the field in connection with the end of the slot in the double-folded field, a triangular cutout is made is.

To illustrate the invention, it is described in more detail below with reference to the "accompanying drawing".

Fig. 1 is a perspective view of a sealed square package with opening device according to the invention.

Fig. 2 is a partial plan view of the opening device of the square package with a curved triangular field.

The square packaging shown in the drawing is generally designated 10 and can be produced, for example, by forming a web into a tube as the starting material and then pressing it flat and sealing it in narrow, parallel, transverse zones, the packaging being filled between two such successive seals . The individual packages can be given their parallelepiped shape before or after the separation of the packages by making cuts in the sealing zones, whereby this is preferably done in a parallelepiped shape by means of a certain longitudinal compression.

The packaging is given the shape described above Side walls 11 and 12 and end walls IJ. The one in the sealing The fins 14 formed extend over the end walls and are bent down towards the end walls 13. The fins 14 run further about four double-walled triangular fields 15 formed during the molding, of which only one is shown in FIGS. 1 and 2. the

the rest are bent over towards the end or soitenwalls (not shown).

ilino end wall 13 has an emptying device in the form of a rectangular slot Id which is mainly parallel with fin I4 and which continues from the end wall in the outer V / and of the triangular field 15 shown, around - as shown in FIG. 2 - at an edge 17 to end, which runs parallel to the edge 18 of the end wall to which the triangular field I5 adjoins, and came about that in the field a triangular cutout 19 through its two walls is made with two mutually perpendicular sides, one of which the Edge 17 and the other one in the extension of one long side of the slot iß running edge 20 forms. A sign-shaped vent hole 21 is made in the end wall 13, and this hole as well as slot 16 and cutout 19 are covered by a closure strip 22, which can consist of durable paper, plastic or the like. This strip extends on one side of the fin I4 along the end wall I3, where it forms a handle part 23 at one end, and then runs over edge 18 to the outside of the triangular field 15 after being bent around the one free edge of the triangular field is, the strip continues to run at the bottom of the field mainly parallel to edge 18, and then, after it has been folded around the other free edge of the triangular array, on the outside of the field across edge 18 to the front wall 13 of the package on the opposite Side of the fin . This strip is glued, heat sealed or fastened in some other appropriate manner, on the packaging and also serves to Halton the field I5 in low-curved position is used, dor Indom to decsen bottom part of the Hlro'ifonu located feolgoklobt or otherwise awockmüoaigor manner on the Verpackungaseite 12 is moored.

When opening the package one takes only the handle end 23 to hand and pulls the strip 22 from the end wall I3 and the

Droiecksfeld 15. rJach your demolition forms there :; Field a pouring spout, and the P'orm dnr grommet can be opened by light pressure on the Types of packaging are to be improved, firstly the front wall IJ and, secondly, the side wall 12 are not buckled, and as it is with this type of rear packaging is known. When pouring out of the packaging, the filling material runs out through the slot 16, namely at the edge 17 all at once collected and straight forward beam.

The packaging described can be improved even further by a simple measure in that at least on the side of the slot 16 that is closest to the fin I4, the two walls of the triangular field I5 along a weld seam * 24, which is parallel to the long sides of the slot runs, welded together, and preferably also on the other side of the slot along a weld seam parallel to it. This primarily eliminates the risk that the filling material will remain in the triangular field and cause spills when the packaging is opened. In addition, one avoids the pouring stream going off at an angle to the side of fin I4. Finally, this allows the part of the fastener strip 22 which covers the triangular cutout 19 and is folded twice there to be removed more quickly and easily by a single pull on the fastener strip.

The invention is of course not restricted to the exemplary embodiment shown and described, but can be modified within the scope of the attached patent claims.
