Definitions

  • the invention relates to a folding box, in particular for granular, free-flowing bulk material, with a pouring opening and a fold-out chute which is pushed into the interior of the box in the rest position and pulled out of the latter in the pouring position, the chute having two triangular wings, one of which has one over it Longitudinally pivotally connected to the box body and the other wing is slidably guided between a double wall of the box body in a guide recess.
  • the invention also relates to a blank for a folding box with two side walls forming the front and the back, two narrow sides connecting the side walls when the blank is erected and folding flaps forming the base and lid, and a side flap provided on a narrow side, which forms the guide recess for the Has chute and from which a wing of the chute is cut out, and which has a side flap which can be folded over the guide recess.
  • Folding boxes designed in this way are generally used for packing bulk goods.
  • Folding boxes for food such as rice, sugar, salt, semolina, etc. and for detergents and the like.
  • Bulkable goods are known which have a pouring opening on a narrow side. This pouring opening is opened via a chute that can be pulled out of the interior of the box and closed again by pressing in this chute.
  • fine-grained bulk goods it has been found that the bulk goods can also trickle out when the folding box is closed.
  • powder not only can considerable losses of the box contents occur as a result, but also considerable contamination of the box body, the area surrounding the box and the user must be expected.
  • the invention is therefore based on the object of developing a folding box of the type mentioned in such a way that it is tight for the contents of the box and at the same time the visual appearance and the overall aesthetic impression are retained.
  • This object is achieved in a folding box of the type mentioned in that the guide recess is surrounded by a membrane.
  • this object is achieved in that a membrane covering the guide recess is placed on the surface of the blank forming the outside of the box.
  • the guide recess in which the chute is guided during the pull-out process is closed by a membrane opposite the interior of the box in the case of the folding box designed according to the invention, so that the contents of the box are retained by the membrane and do not flow into or out of the guide recess and from it into the open can.
  • the interior of the box is thus completely sealed off from the box surroundings by the membrane and is no longer connected via the guide recess, as in the prior art.
  • this wing lies on the side walls with so much play that it is movably guided in the recess that the guide recess is not sealed tightly by the wing alone.
  • escape is thus prevented by the sections of the guide recess which are connected to the box interior being closed by the membrane.
  • the membrane is advantageously a film, in particular made of plastic, a paper strip, a cardboard strip or the like. If the folding box has an inner coating, the film also consists of this material.
  • the membrane preferably forms a shell for the wing of the chute to be inserted into the interior of the box.
  • the envelope hides a complete encapsulation of the guide recess and thus the sliding wing of the chute.
  • the membrane is connected, in particular glued, to the inside of a side wall at least in sections. This ensures that the membrane forms a sealing connection between the side wall of the box and the double wall having the guide recess.
  • the membrane is connected, in particular glued, at least in sections to a side flap which has the guide recess for the chute. The membrane lies on the surface of the side flap facing the interior.
  • the membrane is arranged exclusively on the side flap, in particular is glued to it.
  • the membrane lies at least partially against the side wall adjacent to the guide recess and is connected to it, in particular glued. This results in a further sealing of the guide recess.
  • FIG. 1 a section of a folding box designated overall by 1 can be seen.
  • a side wall 2, a narrow side 3 and a cover 4 can be seen from this folding box 1.
  • the side wall 2 is shown broken.
  • a side flap 6 forming a double wall 5 can therefore be seen, which abuts the inner surface 7 (FIG. 2).
  • the narrow side 3 is provided with a pouring opening 8 and a chute 9 surrounding the pouring opening 8.
  • the chute 9 essentially has two triangular wings 10 and 11, one of which is pivotally connected to the narrow side 3 via its one longitudinal edge 12. This longitudinal edge 12 extends diagonally across the narrow side 3 and ends at a fold 13 connecting the narrow side 3 with the side flap 6.
  • the second wing 11 is pivotally connected to the first wing 10 via its one longitudinal edge 14 and points at the longitudinal edge facing the box body 15 a guide lug 16.
  • This guide lug 16 slides along a guide surface 17 and is supported in the pouring position of the chute 9 from a stop 18.
  • the guide surface 17 and the stop 18 are parts of a guide recess 19 which completely receives the wing 11 in the closed position of the chute 9.
  • the longitudinal edge 15 bears against a stop 20 by which the rest position of the chute 9 is defined.
  • a membrane 21 is shown in FIG. 1, which is shown hatched for better visibility.
  • This membrane 21 completely covers the guide recess 19, so that the stop 18, the guide surface 17 and the stop 20 are overlapped by the membrane 21.
  • the guide surface 17 and the stop 20 form a rear open end 22 of the guide recess 19, which is also covered by the membrane 21.
  • the membrane 21 encompasses not only the side of the side flap 6 visible in FIG. 1, but also the surface of the side flap 6 facing away from the viewer and facing the interior of the box This causes the open end 22 to be closed by the membrane 21.
  • the part of the membrane 21 shown hatched in FIG. 1 is e.g. glued to the inner surface of the side wall 2 by means of an adhesive, so that the bulk material is prevented from entering between the side flap 6 and the side wall 2.
  • the wing 11 also has embossing lines 23 which can be gripped with the thumb 24 when the chute 9 is inserted, and the chute 9 can thereby be brought out of its rest position into the drawn-out pouring position.
  • the folding box blank 25 shown in FIG. 2 has a narrow side 27 connected to the side wall 2 via a fold 26 and a further side wall 29 via a fold 28, to which the narrow side 3 is connected via a fold 30.
  • the side flap 6, which is connected to the narrow side 3 via the fold 13, is itself provided with a fold 31 which divides the side flap 6 into approximately two equally wide longitudinal strips 32 and 33.
  • the side walls 2 and 29 are provided with cover or bottom flaps 34 and 35 or 36 and 37, and the narrow sides 3 and 27 are equipped with folding flaps 38, 39 and 40, 41. If the cover flaps, bottom flaps and flap flaps 34 to 41 are folded over on one another, they form the cover 4 and a base (not shown) of the folding box 1.
  • the contour of the recess 24 can be seen, which is provided in the side wall 2 or at the edge thereof. It can also be seen that the wing 11 is cut out of the longitudinal strip 32. Between the wing 11, the open end 22, which is flush with the fold, the guide surface 17 and the stop 18, a recess is punched out, in which the guide lug 16 moves. It can also be seen that the upper, horizontal edge 42 is connected to the narrow side 3 via perforation strips. The longitudinal edges 12 and 14 are formed as folds, so that when the chute 9 is actuated, the wing 10 can move out of the plane of the narrow side 3. When the folding box 1 is opened for the first time, the perforation of the upper edge 42 tears and the pouring opening 8, which has a cross section corresponding to the wing 10, is free.
  • a dot pattern on the longitudinal strip 32 and the side wall 2 indicates adhesive strips 43 and 44 on which a suitable adhesion promoter, e.g. a hot melt adhesive, a pressure sensitive adhesive or the like is applied.
  • the longitudinal strip 33 is connected to the longitudinal strip 32 via the adhesive strip 43, so that the guide recess 19 is covered from this side.
  • the rear side of the longitudinal strip 32 facing away from the viewer in FIG. 2 is fixed on the side wall 2 via the adhesive strip 44 with the membrane 21 interposed, as can be seen more clearly from FIG. 3.
  • the box sleeve is formed so that the folding box blank 25 can be erected.
  • the arrangement of the membrane 21 on the rear side of the folding box blank 25 facing the viewer in FIG. 3, which forms the outer surface of the folding box 1 when the blank is erected, can be clearly seen from FIG. 3.
  • the membrane 21 extends over the entire width of the longitudinal strip 33 and almost over the entire width of the longitudinal strip 32, the left edge being at a short distance from the fold 13. This is necessary in order to keep the embossing lines 23, which emerge from the recess 24, free.
  • the membrane 21 extends at least over the entire length of the guide recess 19 including the wing 11. This ensures that the guide recess 19 is also sealed from this side. Since the membrane 21 extends from the longitudinal strip 32 over the fold 31 to the longitudinal strip 33, the open end 22 is also when the longitudinal strip 33 is folded over and glued to the longitudinal strip 32 locked. No bulk material can thus emerge via the guide recess 19, since this is overlapped on one side by the longitudinal strip 33 and on the other side by the membrane 21 and is thereby sealed. Furthermore, the section of the membrane 21, which is located on the longitudinal strip 32, is sealingly connected to the side wall 2 via the adhesive strip 44.
  • This invention has the advantage that no bulk material can escape from the inside of the box when the chute 9 is closed.
  • the aesthetic appearance of the folding box 1 is neither adversely affected by security labels or the like stuck on the outside.
  • no additional work step is required to apply a security label, so that the workflow in the bottling plants is shortened.
  • the folded box 1 can be delivered in the collapsed state with the membrane 21 applied directly from the folding box manufacturer to the bottling plant and can be handled there as usual folding boxes.
