Definitions

  • the innovation has the task of creating a repeatedly closable tear tab opening with a spreading or dosing device, which is produced from the packaging material itself or applied to the packaging.
  • a multilayer overlay preferably takes place in at least one edge region thereof.
  • This is advantageously achieved, for example, on the packaging base or on the top of the packaging, where the adhesive edges are already superimposed by conventional production.
  • This adhesive edge may not need to extend over the entire length of the corresponding packaging wall.
  • the gluing takes place along the edges of the adhesive edge.
  • a safety flap with predetermined breaking lines can be provided from the outside inwards, which partially overlaps a longer tear flap which can extend over a single surface or extend over two surfaces adjacent to one edge.
  • the reduction in cross-section, which determines the predetermined breaking lines of the tear tab, can be achieved by bevel cuts, whereby fraying is achieved at the opposite slope on the two parallel predetermined breaking lines, which favors a hold on repeated pressing of the tab in the closed position.
  • the reduction in cross section on the pull tab can be done over the entire length by a series of sloping or straight cuts are formed or are formed for the part covering the spreading device of straight cuts and on the "adhesive part" of oblique cuts.
  • the adhesive effect for the tear tab can be promoted by providing a space between the layer having the safety tab and the layer having the tear tab, which is achieved by a corresponding cutout of an adhesive edge located therebetween, so that grooves are formed on the side, which are suitable pick up the side edges of the pull tab as soon as it is pressed into the closed position.
  • the adhesive edge covered by the tear tab has a scattering or metering device which consists of one or more openings which are calibrated depending on the grain size, grain shape and type of content.
  • this area can also be formed by at least one component which is made of a different material than that of the packaging.
  • Fig. 1 shows part of the development of a box, along the side with the adhesive edges, with a tear tab opening and spreading device in the area of a box corner.
  • Fig. 2 is a perspective view of the innovation device in the closed position.
  • Fig. 3 is a perspective view of the innovation device in the open position.
  • Fig. 4 is a sectional view through the superimposed adhesive edges of the packaging in the area of the device according to the innovation.
  • Fig. 5 shows a perspective view of the device according to the innovation with tab holder in the closed position.
  • FIG. 6 shows a perspective view of the device according to the invention according to FIG. 5 in the open position and with the pull tab secured in this position.
  • the development of the box 1 has the adhesive edges 1a, 1b, 1c, 1d, 1e, which overlap when the box is glued, as can be seen from FIGS. 3 and 4.
  • the box is preferably glued along the edge region 7 in that the corresponding adhesive edge 1e overlaps the adhesive edge 1a.
  • the adhesive edge 1a corresponding to the adhesive edge 1e need not have the same length extension as this.
  • Openings 2 are provided on the adhesive edge 1a, which, when the box is assembled, are overlaid by the tear tab 5, which extends beyond the edge of the box; this tab 5 has a hinge line 5b, a handle part 5d and parallel, lateral predetermined breaking lines 5a, which are formed by cuts with opposite slopes.
  • the adhesive edge 1d which covers the adhesive edge 1e having the tear tab 5, is cut out in such a way that there is a free space between the adhesive edges 1e and 1b; this space is advantageously wider than the pull tab 5 and also wider than the safety tab 3, which may have the same width as the pull tab 5.
  • the tear tab 5 is closed repeatedly, it is held in the closed position by pressing against the spreading device 2, in that the lateral edges penetrate into the space between the glue edges 1a and 1b.
  • a punched-out area 3d can also be provided on the upper packaging surface 1b (FIGS. 5, 6) in an area slightly behind the hinge line 3b of the safety tab 3, as a result of which two tongues 3c are formed which are suitable for holding the tear tab 5 in the open position (Fig. 6).
