Definitions

  • the invention relates to a folding box with a bottom, front wall, rear wall and side walls consisting of a lower part and a lid part which is hinged to the rear wall of the lower part and has at least partially covering wall strips of the other walls of the lower part.
  • the present invention has for its object to provide a folding box that is relatively tightly closed on the one hand so that sensitive products such as ice cream, butter and the like are not affected by oxygen, but on the other hand to remove the contents is easy to open.
  • cover part is detachably connected to the front wall of the lower part via a front wall strip and the side wall strips of the cover part are fixed to the side walls of the lower part with reduced holding force.
  • All wall strips of the cover part overlap the lower part and are fixed to it, so that an adequate seal is ensured. Nevertheless, it is easy to open, since the connection of the front wall strip can be released and the connection of the side wall strips can be canceled without difficulty by reducing the holding force.
  • An advantageous embodiment of the invention is that in the front wall strips of the cover part a tear line running across this entire section is provided, which is formed by a perforation, and that only the part of the front wall strip separated from this tear line is sealed or glued to the front wall of the lower part connected is.
  • the front wall strip of the cover part is divided into two parts by a tear strip, of which only the one removed from the cover is connected to the front wall of the lower part by sealing or gluing.
  • the tear strip is to be separated along two perforation lines, there is no need to detach it from the front wall of the lower part, so that only a small amount of force is required to open the folding box.
  • Front wall strips of the cover part, a projection or the like is provided, which is connected to the front wall of the lower part by sealing or gluing, and that the connection point of the lower part is divided by a cutting line, the depth of which is less than the material thickness.
  • the opening is gripped and the material is cut out along the cutting line from the front wall of the lower part.
  • This opening is particularly easy to do.
  • the strength of the closure is sufficient to prevent accidental opening.
  • An advantageous development of the invention also lies in the fact that the sealing force of the seal between the cover part and the lower part is reduced at least in the area of the side walls by overprinting the sealing medium with printing ink. This type of reduction of the sealing force is particularly easy to carry out.
  • the section of the side wall strips of the cover part facing the rear wall is subdivided by a perforation line extending from the articulation point of the cover on the rear wall and running obliquely downwards.
  • the side wall strip is cut along this perforation line when the folding box is opened. This makes it possible to move behind the perforation line, i.e. H. on the side facing the rear wall, firmly seal the part of the side wall strip and fix the part in front with reduced sealing force.
  • a very stable and largely sealed lower part is achieved in that, according to the invention, the mutually adjacent walls of the lower part are connected to one another by gusset surfaces which are glued or sealed onto the outside of the side walls.
  • the sealing or gluing of the gusset surfaces is designed to be easily detachable.
  • connection areas delimited by cutting lines in which material splitting is carried out can be done again, for example, by reducing the sealing force by overprinting with printing ink; however, it is also possible to provide connection areas delimited by cutting lines in which material splitting is carried out.
  • tabs are formed on the gusset surfaces which have no sealed connection to the adjacent side wall.
  • the gusset surfaces can be easily grasped and detached, whereby the lower part can be laid flat for easier removal of the contents.
  • FIG. 1 in FIG. 1 denotes a blank which comprises a top wall 2, a rear wall 3, a bottom wall 4 and a front wall 5.
  • a front wall strip 6 is formed on the cover wall 2 and bears against the outside of the front wall 5 in the erected state of the folding box.
  • a perforation line 7 runs in this front wall strip 6 and divides a tear strip 8 from the front wall strip.
  • two side wall strips 9 are articulated on the cover wall 2 and are divided at their end facing the rear wall 3 by an oblique perforation line 10.
  • Two side walls 11 are articulated on the bottom wall 4, which in turn are connected to two gusset surfaces 12 which are articulated on the rear wall 3.
  • the two side walls 11, the front wall 5 and the rear wall 3 are bent downwards by 90 ° and the gusset surfaces 12 and 13 are folded out onto the side walls 11 and sealed with them.
  • the surfaces 14, 15 and 16 are then in a row; they are coated with printing ink so that the sealing force is reduced there.
  • the two side wall strips 9 of the cover part are then sealed together with these two rows of surfaces.
  • the section 17 of the side wall strips divided by the perforation line 10 is sealed together with the section of the gusset surface 12 lying between the surface 16 and the rear wall 3, the sealing force not being reduced in this sealing area.
  • the integrally formed on the front wall strip 6 tabs 18 are connected to the side wall strip 9, is sealed to the located in the front wall 5 strips 19 while the tear strip 8, which also - is covered with printing ink - to reduce the sealing force.
  • the tear strip 8 is detached from the front wall strip 6 along the perforation line 7 and at the same time detached from the front wall 5. Then the remaining front wall strip can be grasped and the cover part pulled up.
  • the two side wall strips 9 are detached from the surfaces 14, 15, 16. However, the sealing of the sections 17 holds on the gusset surfaces 12, which is why the perforation line 10 tears open.
  • the lid part After removing a portion of the contents, the lid part can be opened again without difficulty on the lower part, a comparatively tight closure being achieved.
  • FIG. 2 shows a blank 20 which again has a top wall 2, a rear wall 3, a bottom wall 4 and a front wall 5.
  • a front wall strip 21 is formed on the cover wall 2, a section 23 of which is sectioned off by a tear strip 22.
  • Sealing flaps 24 are formed on the side of this front wall strip 21 and are connected to side wall strips 25 articulated on the cover wall 2 when the folding box is erected.
  • This side wall strip 25 there are again perforation lines 26 which divide sections 27 facing the rear wall 3 from the side wall strips.
  • the rear wall 3 is laterally connected to gusset surfaces 28 which are articulated with their second side to side walls 29 of the lower part. Corresponding gusset surfaces 30 are formed on the opposite side of these side walls 29 and connect them to the front wall 5.
  • Circular cutting lines 31 are provided on the outside of the side walls, the depth of which is less than the material thickness. Within these circular cutting lines 31, when the bottom part of the folding box is erected, the connection between the side walls and the gusset surfaces resting on the outside thereof takes place. As a result, the lower part of the folding box can also be opened in a simple manner for easier removal of the filling material. These delimited areas of the side walls are connected to the gusset areas by sealing or gluing. It is possible to connect further sections of the side walls to the gusset surfaces, but then with reduced sealing force. In order to facilitate the tearing open of the lower part, tabs 32 are formed on the gusset surfaces, which are not fixed on the side walls and can therefore be easily grasped for opening.
  • a top wall 2, a rear wall 3, a bottom wall 4 and a front wall 5 are again provided.
  • gusset surfaces 34 are articulated, which, like gusset surfaces 35 articulated between the rear wall 3 and the side walls 33, are folded and connected to the outside of the side walls 33 when the bottom part of the folding box is erected.
  • top wall 2 On the top wall 2, side wall strips 36 and a front wall strip 37 are formed, which can be connected via tabs 37 formed on the front wall strip 37.
  • an extension 39 is formed on the front wall strip 37, which is connected to the front wall 5 when the folding box is closed.
  • a circular cut line 40 is provided in the outer side of the front wall in the overlap area, as a result of which the material lying within this cut line is partially detached when the folding box is opened.
