Definitions

  • the invention relates to a folding box with a rectangular cross-section with an inner frame and a hinged lid, which has at least three free sides with vertically angled edges, which bear directly against the collar formed by the frame when the folding box is closed.
  • folding boxes can be made from a wide variety of blanks. Examples are folding boxes with an inner frame made from a two-piece blank, folding boxes with a hinged inner frame made from a one-piece, seven-sided blank and folding boxes to be filled from the side.
  • a folding box with hinged lid and frame is formed, which forms a collar protruding towards the opening, over which the lid with its edges is placed.
  • the cover can be articulated both on the upper edge of a side wall, but also along a line at the level of the lower collar area. In the latter case there is a lid with edges angled on all four sides.
  • the frame is u with these folding box constructions. a. needed to improve the resealability.
  • the frames cannot be glued to the entire surface of the inner surfaces of the side walls in such folding box constructions. Rather, they are only partially attached to them so that an open gap is formed between the outer wall and the frame. Due to the filling process as well as loads and manipulations such as pressing and turning the folding box, product can get between the frame and the folding box, which falls out of the box when it is opened for the first time. The same can also happen if the opened but reclosed container is exposed to the prescribed loads.
  • the problem underlying the invention is the improvement of such folding box designs in that no product can fall between the frame and the folding box.
  • This problem is solved according to the invention in that a sealing lip is articulated on the upper edge of at least one frame side and is slightly deflected inward, which resiliently abuts the cover when the cover is closed.
  • Such a resilient sealing lip on the lid prevents powdered or granulated product from reaching the area from which it would fall into the gap between the frame and the outer wall, even under mechanical loads on the container.
  • the arrangement of such a sealing lip also has the advantage that the folding box is protected against bulging and has a significantly increased transverse stability.
  • the sealing lip Due to the rigidity of the frame material, from which the sealing lip is made, it has a restoring force, so that when the lid is opened it largely straightens up again and largely releases the opening cross-section. This restoring force also ensures that the frame which bends under mechanical load with a hinged sealing lip is restored to its original shape after the load has been removed.
  • the sealing lip extends over the entire width of a frame side, as a result of which the sealing effect is improved.
  • sealing lips are provided on adjacent sides of the frame, the side edges of the adjacent sealing lips are removed by 45 ° to the inside, so that when the adjacent sealing lips are deflected by the cover closure, the sealing lips contact one another and do not lead to jamming or overlapping to form gaps.
  • 1 is a folding box according to the invention with a sealing lip
  • Figure 2 shows another embodiment with four sealing lips and a cover with four edges.
  • Fig. 3 shows schematically the sectional side view of a corner of a closed folding box
  • Fig. 4 shows the schematic representation of FIG. 3 under load.
  • the folding box 1 shown in FIG. 1 has a lid 4 hinged to the upper edge of a side wall 7, which has vertically hinged edges 5 on its free sides.
  • a sealing lip 6 is articulated on the upper edge of the frame side 2 opposite the articulation of the lid and is slightly deflected inwards. If the folding box 1 is closed by closing the lid 4 closed, the lid edges 5 put over the frame collar 3, which projects beyond the side walls 7 of the folding box 1 upwards.
  • the cover 4 When the cover 4 is folded over to close the folding box, the cover 4 abuts the upper edge of the sealing lip 6 and presses it further inwards. Due to the material rigidity, the sealing lip 6 has a restoring force, whereby it rests resiliently on the cover 4. In this way, product present in the folding box, which is usually powdery or granular or consists of small beads in such folding boxes, is prevented from getting into the space between the sealing lip 6 or front frame collar 3 and front cover wall 5 and thereby into the gap to fall between the front frame wall 2 and the front folding box wall 7.
  • FIG. 2 differs from the folding box according to FIG. 1 essentially in that it has four sealing lips 6, which are articulated on each of the frame collar walls 3, and a cover 4, which on the rear folding box wall 7 at the level of lower collar area 3 is articulated and has four deflected edges 5.
  • the sealing lips are chamfered inwards by 45 ° on the side edges, which are adjacent to the other sealing lips 6, so that the sealing lips 6, when they are bent downward by the cover 4, lie against one another.
  • a folding box corner is shown in section, which is still closed.
  • a side wall of the folding box can be seen, which is composed of the folding box side 7 and the lid edge 5, between which a tear tape 9 is also arranged.
  • the cover 4 presses the sealing lip 6 down in this state.
  • the gap between the side wall 7 and the frame 2 is shown exaggeratedly large in order to clarify the problem.
  • the product 8 is indicated inside the folding box 1.
  • FIG. 4 shows the same situation as in FIG. 3, but this time taking into account a force acting laterally on the folding box 1, which is indicated by an arrow. Under the influence of this lateral force, the folding box 1 would become entangled in the way that is illustrated by the solid lines. If the sealing lip 6 according to the invention were not now articulated on the frame wall 2, the product 8 would pass over the frame 2 and fall into the gap between the side wall 7 and the inner frame 2. It is clearly illustrated how such an overflow of product 8 is prevented by the arrangement of the sealing lip.
