Definitions

  • the invention relates to a folding box, in particular made of cardboard, with two main wall sections which are connected to one another on one side, in particular by a main folding line, and which can be connected to one another on the opposite side, for example by a flap, in order to form a substantially tubular body form, the ends of which can be closed.
  • the invention also relates to a folding box made from a one-piece blank.
  • closure sections are formed which can be folded onto one another to close the pillow pack.
  • the closure sections also serve to shape and hold the essentially tubular body.
  • the closure sections of pillow packs are, for example, elliptical. Due to the non-rectangular contour of the closure sections, a rectangular cut cannot be used for pillow packs. This requires an intermediate cut between two blanks during production.
  • the non-rectangular contour of the closure sections leads to pillow packs to an increased material consumption, since the material between the closure sections of two different blanks has to be removed.
  • closing the pillow packs by hand is relatively complex since the closure sections have to be folded against one another one after the other.
  • pillow packs cannot be sealed in a fluid-tight manner by welding or sealing.
  • the object of the invention is to provide a simple and inexpensive to produce blank for a folding box that can be closed by hand.
  • Another object of the invention is to provide a folding box from a one-piece blank, which is simple in construction and inexpensive to manufacture.
  • the folding box according to the invention should be particularly easy to close by hand and also by machine.
  • the object is in the case of a one-piece, in particular rectangular, blank for a folding box, in particular made of cardboard, with two main wall sections which are connected to one another on one side, in particular by a main folding line, and which can be connected to one another on the opposite side, for example by a flap
  • a side wall section with tapered ends is formed in at least one of the two main wall sections.
  • the side wall section gives the tubular body a stable spatial shape.
  • a preferred exemplary embodiment of the blank is characterized in that the side wall section is formed by two fold lines which are spaced apart in the middle and merge into one another at the ends.
  • the fold lines give the tubular body a polygonal cross section.
  • two side wall sections are arranged opposite each other to give the tubular body a rectangular cross section in the middle.
  • Another preferred exemplary embodiment of the blank is characterized in that the two fold lines forming the side wall section are arranged parallel to one another in the central region. This gives the tubular body the shape of a cuboid in the central area.
  • Another preferred exemplary embodiment of the blank is characterized in that the side wall section is triangular at its ends. This gives the cross section of the tubular body special stability.
  • Another preferred exemplary embodiment of the blank is characterized in that the side wall section has the shape of an ellipse. This leads to an optically appealing shape of a folding box formed from the blank.
  • the cross section of the tubular body decreases from the center to the outside.
  • Another preferred exemplary embodiment of the blank is characterized in that the main wall sections merge into closure sections at the pointed ends of the side wall section.
  • the closure sections come into contact with one another in the assembled state of the folding box. This enables a particularly simple closing of the folding box by hand and by machine.
  • closure fold lines are formed between the main sections and the closure sections.
  • the closure fold lines enable the closure sections to lie flat against one another. This enables a fluid-tight closing of the folding box.
  • a further preferred exemplary embodiment of the blank is characterized in that the closure fold lines are arranged essentially transversely to the at least one side wall section, and in that the distance between the closure fold lines and the associated edge of the respective closure section is not constant or varies. This ensures that packaging made from the blank is securely closed.
  • a further preferred exemplary embodiment of the blank is characterized in that a side wall section with pointed ends is formed in both main wall sections, and that a continuous fold line is arranged essentially parallel to the side wall sections between the two side wall sections.
  • the continuous folding line ensures that the tubular body is folded up for storage or transport.
  • the continuous folding line simplifies machine production on conventional gluing machines and makes it easier to insert products.
  • Another preferred exemplary embodiment of the blank is characterized in that the distance between the closure fold lines and the associated edge of the respective closure section increases inwards and outwards from the side wall sections. It is thereby achieved that the closure sections which abut one another in the erected state of the folding box are held together. The course of the closing folding lines creates a tension in the erected folding box, which keeps the folding box closed.
  • Another preferred exemplary embodiment of the blank is characterized in that the distance between the closure fold lines and the associated edge of the respective closure section increases linearly inwards and outwards from the side wall sections.
  • the resulting straight fold lines have the advantage that they are easy to manufacture.
  • closure fold lines are designed in the shape of a circular arc, with respect to the blank, to be curved inwards.
  • a slightly curved design of the closure fold lines has proven to be particularly advantageous.
  • the curvature of the closure fold lines ensures that the closure sections snap in when a folding box made from the blank is closed.
  • a further preferred exemplary embodiment of the blank is characterized in that the distance between the closure fold lines and the associated edge of the respective closure section is constant in the area within the two side wall sections and increases outwards in the areas outside the two side wall sections.
  • the closure sections are pretensioned in the closing direction when the folding box is assembled. The pretensioning ensures that the closure sections snap or go together when the folding box is closed.
  • a further preferred exemplary embodiment of the blank is characterized in that on the side of one of the side wall sections opposite the continuous fold line, a flap on the associated main wall section is formed by a further fold line, which is arranged parallel to the continuous fold line.
  • the tab serves to connect the two wall sections together.
  • Another preferred exemplary embodiment of the blank is characterized in that the continuous fold line and the further fold line are arranged substantially congruently in the assembled state of the folding box. This ensures that the blank folds up even when the two wall sections are connected to one another on two sides in order to form the tubular body.
  • a pouring funnel is formed on one of the tapered ends of the side wall section.
  • the pouring funnel is used to pour out a fluid located in the closed folding box.
  • the pouring funnel can also be used to fill a fluid.
  • a further preferred exemplary embodiment of the blank is characterized in that the pouring funnel is formed with the aid of five pouring funnel folding lines which are formed in the closure sections arranged at the tapering end of the side wall section. The five fold lines make repeated opening and closing of the pouring funnel in the erected state of the folding box is ensured.
  • Another preferred exemplary embodiment of the blank is characterized in that the distance between the pouring funnel fold lines from one another decreases toward the associated tapering end of the side wall section. This ensures a funnel-shaped expansion of the pouring funnel to the outside.
  • Another preferred exemplary embodiment of the blank is characterized in that in the region of the pouring funnel a triangular projection with the tip facing outward is arranged on the two associated closure sections.
  • the triangular approach in conjunction with a centrally arranged pouring funnel folding line serves to ensure targeted pouring.
  • a closure flap is provided on the outside of the pouring funnel, which can be separated from the two adjacent closure sections by at least one perforation line.
  • the sealing tab serves to keep the pouring funnel closed. After removing the sealing flap, the pouring funnel can be opened.
  • the above-mentioned object is achieved in the case of a folding box from a one-piece blank in that the folding box has a body in the assembled state, which has two ends tapers outwards and has a substantially rectangular cross section in the middle.
  • the shape of the folding box resembles a foil bag welded at the ends.
  • the shape results from the solid content.
  • the shape is generated by the fold lines.
  • the folding box according to the invention has the advantage that it can be delivered lying flat.
  • it has its own body, defined in size and shape without a product, and a functioning closure unit. It can be erected both by hand and by machine.
  • the blank according to the invention can be processed on conventional production machines without additional devices.
  • the folding boxes can be produced in many variants, for example as a carrier pack, or with special features such as closures and tear-open techniques.
  • a preferred embodiment of the folding box is characterized in that the body has two side wall sections tapering outwards.
  • the side wall sections give the erected folding box stability.
  • the erected folding box is given the shape of a cuboid, for example, with two opposite, tapering ends.
  • FIG. 1 Another preferred exemplary embodiment of the folding box is characterized in that two flat closure regions are formed on the ends of the body which taper to the outside are.
  • the flat closure areas enable the carton to be closed fluid-tight, for example by welding.
  • the closure areas enable the folding box to be closed and reopened by hand.
  • the special arrangement of the closure fold lines ensures that the closure areas snap in and hold together without having to use other techniques or aids.
  • the closure areas can also be sealed or glued.
  • FIG. 1 Another preferred exemplary embodiment of the folding box is characterized in that the main and side wall sections are each separated from one another only by a fold line.
  • a folding line between a main wall section and the adjoining side wall section gives the folding box a defined shape in the erected state.
  • a further preferred exemplary embodiment of the folding box is characterized in that an incision is provided in at least one of the closing sections, into which a tab can engage, which is formed on the closing section which comes into contact with the closing section with the incision when the folding box is erected.
  • the flap and the incision make it easy to close the folding box when it is erected.
  • This closing mechanism provides the advantage that it is easy to implement on the one hand, since no additional fastening means are required, and on the other hand ensures that the folding box is opened and closed several times.
  • a further preferred exemplary embodiment of the folding box is characterized in that the incision has the shape of a circular arc which, in relation to the blank, is curved inwards. This shape of the incision has proven to be particularly advantageous in practice.
  • the folding box is characterized in that the flap is formed by an incision which has the shape of a circular arc which, in relation to the blank, is curved inwards. This shape of the incisions ensures that the folding box is easily closed when it is erected.
  • a further preferred exemplary embodiment of the folding box is characterized in that at least one flap is formed in at least one closure section, which in the erected state of the folding box comes to rest on an adhesive surface which is formed on an adjacent closing section and is covered by the flap.
  • the associated sealing sections are also in contact with one another and the folding box is closed.
  • the connection becomes the locking section solved with the adhesive surface and the abutting closure sections can be removed from each other.
  • Another preferred exemplary embodiment of the folding box is characterized in that the adhesive surface is delimited by a scoring.
  • the scoring preferably extends only in an upper layer of the blank. The scoring ensures a defined tearing out of the top cut layer. On the one hand, this ensures that the tamper-evident seal cannot be restored. On the other hand, the outside of the closure section equipped with the adhesive surface remains intact even after the top cut layer has been removed, that is to say the visual impression is not impaired.
  • a major advantage of the folding box according to the invention is that a one-piece, square blank can be used. This makes it possible to manufacture the folding boxes without new technical equipment.
  • the simple and quick closure of the folding box due to the distance of the closing folding lines from the associated edge of the closing sections ensures that the folding box can be laid flat again after use.
  • the carton When folded, the carton can either be sent to a recycling cycle, or it can be erected by hand or by machine.
  • the possibility of the closure sections Welding or sealing the folding box to one another is particularly important in the food sector and in general in the case of powdery and liquid products.
  • the closure sections can also be designed as handles or can be provided with a so-called euro hole.
  • the folding box according to the invention is particularly well suited as a gift pack, for example for lingerie, accessories or jewelry.
  • the folding box is also suitable for holding confectionery, household goods, office supplies or food. Since the folding box can be sealed, it is also suitable for holding powders and liquids.
  • the folding box according to the invention has a particularly appealing design when erected. Due to the attractive design and the tapered sealing flaps, the folding boxes are also suitable as a display in a decorative wall.
  • a tension is generated which, when the folding box is closed by hand, ensures that the closure sections snap shut.
  • the pouring funnel integrated in the closure sections can be closed again and again after opening. As a result, it offers the contents of the folding box protection against pests and dirt even after opening. It is also easy to use.
  • the blank according to the invention can be equipped with pre-gluing points or can be machine-printed, punched and erected on a machine. In the latter case, it is also possible to do without the fold lines. This makes the package more stable and results in a package image without annoying lines. In addition, depending on the appearance of the printed image, the closure area can be moved.
  • a rectangular blank 1 is shown in plan view.
  • a large number of fold lines are attached to the blank 1.
  • the fold lines can be folds, creases, scratches or perforations.
  • the fold lines serve to form defined sections when the blank 1 is erected into a folding box.
  • the blank 1 comprises a main section 5 which has two sections 3 and 4 and a main section 9 which has two sections 7 and 8.
  • the main sections 5 and 9 are separated from one another by a main folding line 10.
  • the main sections 5 and 9 have the shape of rectangles which abut one another on one of their long sides.
  • the side wall section 11 is formed by two side wall folding lines 14 and 15 which run parallel to one another in the central region and taper towards one another at the ends. At the pointed ends, the side wall folding lines 14 and 15 merge into end folding lines 22 and 23.
