Definitions

  • the present invention relates to a folding box with tamper-evident closure according to the preamble of claim 1, and a method for its production.
  • the boxes are provided with a tamper-evident seal, i.e. the boxes are closed in such a way that any unauthorized opening can be seen on the way between the manufacturer and the consumer.
  • a known tamper-evident closure of medicament boxes consists of adhesive labels which are glued to the generally rectangular boxes at the point at which the insertion flap of the closure part is inserted under the corresponding surface of the box body.
  • this type of tamper-evident closure is not completely satisfactory, particularly with regard to the security against an undetectable opening and closing of the box.
  • the application of the adhesive labels requires too much effort when packaging the pharmaceuticals.
  • a special machine unit must be inserted into the packaging line, which causes considerable space requirements and investment costs.
  • the available machine units for this purpose do not achieve the required performance. Further delays arise from the inevitable changing of the roll with the adhesive labels.
  • the adhesive labels themselves also cause considerable additional costs. They also undesirably influence the design of the folding box.
  • the object of the present invention is to provide folding boxes with tamper-evident closure and a method for their production which meet the requirements mentioned.
  • the invention is largely based on the knowledge that a hot-melt adhesive material, such as is often used in packaging technology for the bonding of flat surfaces of boxes, can surprisingly also be used as a seal.
  • the hot melt adhesive material is not, as usual, applied to a cardboard surface and then another cardboard surface is pressed against the adhesive layer, but instead of two overlapping cardboard surfaces, the upper one has a recess against which the jet of hot melt adhesive material is directed from a nozzle.
  • the hot-melt adhesive spreads in the heated and liquid state on the surface of the lower cardboard layer lying under the recess and wets the edge of the recess, whereby it also penetrates under the edge of the recess into the slot between the two cardboard layers.
  • the nozzle for applying the hot melt adhesive is so directed that the edge of the recess is also wetted.
  • the edge of the recess is preferably corrugated. Instead of the wavy design, the edge can also be serrated, provided that this does not result in any technical problems when closing the box. Such a design deviating from the straight course results in a greater durability of the seal and it is practically impossible to open the seal with a sharp knife without this becoming visible. This measure is advantageous from a manufacturing point of view because it enables greater tolerances in the setting of the spray nozzle.
  • Hot melt adhesives can be composed in various ways. In any case, these are materials that are solid at room temperature and are heated for gluing. In doing so, they become fluid. They have the property of spreading on the layers to be bonded and forming an adhesive contact with them. After application, the adhesive solidifies as the adhesive solidifies. Particularly suitable for the invention are adhesives which form an intimate connection with the lacquer used for the folding box and thereby have a particularly good adhesive effect.
  • the softening temperature of the hot melt adhesive material is high enough. It must be so high that at the temperature at which the seal can be opened, the box shows visible traces of the opening.
  • a hot-melt adhesive material is preferably used, which quickly solidifies after application.
  • the solidification must take place, for example, in about 3 seconds in order not to impair the subsequent processing processes of the folding box.
  • FIG. 1 shows the cut of a folding box 2 according to the invention.
  • the six sides of the box can be used as the front 4, back 6, left side 8, right side 10, bottom 12 and top 14 using the designations customary in the pharmaceutical packaging industry describe.
  • the adhesive flap 16 and four dust flaps 18 can also be seen in FIG. 1.
  • the box is formed in a known manner by gluing the adhesive flap 16 to the back of the right side 10.
  • the box has at least one recess for producing a tamper-evident closure.
  • recesses 22 and 24 can be seen on the front side 4 and on the rear side 6. These have an elongated shape and run parallel to the edge 26 of the front side 4 and to the edge 28 of the rear side 6.
  • the edges 26 and 28 are those edges of the folding box under which the insertion tabs 20 are inserted when the box is closed.
  • the edge of the recesses 22 and 24 is corrugated, as can be seen from the figure.
  • the recess springs back in the course of the waves by a minimum of 1 mm (dimension a) and a maximum of 2 mm (dimension b) with respect to the edge 26 or 28.
  • the recesses 22 and 24 are surrounded by tear perforations 23 and 25, which serve to open the folding box in a known manner.
  • FIG. 1 broken lines are drawn in at two other locations of the folding box, which are alternatively possible for a tamper-evident closure according to the present invention.
  • Such recesses can, although less preferred, be provided instead of the recesses 22 and 24 in the blank 2 for the tamper-evident closure according to the invention. All of the recesses have in common that they are provided at such a point on the folding box where, when the folding box is closed, there is another cardboard surface behind the recess.
  • the positions are selected so that when the recess and the cardboard surface located behind it are sealed to one another according to the invention, it is no longer possible to open the folding box without breaking the seal.
  • the box When the box is closed, there is a dust flap 18 behind each of the recesses 30 and 32.
  • the insertion flaps 20 are located behind the recesses 22 and 24.
  • injections 21 are provided in the area behind the recess, in particular in the insertion flap 20.
  • Fig. 2 illustrates the process of sealing after closing the folding boxes.
  • Two slide rails 34 can be seen, on which the boxes 2, 2 ', 2 "are transported from left to right with the aid of a mechanism (not shown in more detail).
  • the boxes are carried along by holders 36 and moved in parallel along the slide rails Fig. 3 processing stations, in which the folding boxes 2, 2 'and 2 "are located.
  • the folding box labeled 2 is already filled and closed. It passes through the beam marked S with a transmitter 37 and a receiver 38. This makes it possible to very precisely determine the position of the folding box shortly before the hot melt adhesive is sprayed on.
  • the folding box designated 2 ' is in a processing position in which hot melt adhesive is sprayed from the hot melt spray nozzles 40 and 42 onto the recesses 22 and 24.
  • the spraying process is based on the position determination with the help of the light barrier 37, 38 controlled so that it starts when the first end 27 of the recess 22 in the direction of the transport process is in front of the spray nozzle 40 and that it is ended when the other end 29 of the recess 22 is in front of the spray nozzle.
  • the folding box 2 ′′ is shown in a position in which the hot-melt adhesive solidifies.
  • a ventilation device 48 which is only shown symbolically, can be provided, by means of which the corresponding point of the folding box is cooled.
  • the spray nozzles for spraying the hot-melt adhesive material onto a box which in the above-mentioned preferred manner has the recesses 22 and 24 on the edges 26 and 28 opposite the insertion tabs 20, at an angle a to which the recesses 22 and 24 having surface 4 and 6 are inclined.
  • This angle is preferably approximately 5 ° to 60 °, particularly preferably 25 to 40 °, in practice an angle setting of 30 ° has proven particularly useful.
  • the figures show a particularly preferred embodiment of the invention, in which the recess is located at a certain point, namely on the edge 26, 28 opposite the insertion tab 20, and in which the hot-melt adhesive material is sprayed on in a very simple manner stationary spray nozzles 40, 42 takes place at a certain angle.
  • This combination of measures achieves particularly reliable sealing in a particularly simple manner.
  • the method is particularly simple because hot melt adhesive spray nozzles only have to be attached to a normal location on a normal packaging machine at a suitable point on the folding box transport path, a hot melt adhesive spray nozzle 40, 42 being provided for each closure part 14, 16 of the folding box 2.
  • the hot-melt adhesive also penetrates under the edge of the recess (at 53), ie between the insertion tab 20 and surface 4, which results in a particularly firm connection.
  • the edge of the recess at 53
  • ie between the insertion tab 20 and surface 4 results in a particularly firm connection.
  • the layer thickness of the hot-melt adhesive material applied is also of particular importance for good sealing.
  • a layer thickness of approximately 1 mm has proven itself in practice.
  • other layer thicknesses between approximately 0.2 mm and 2 mm can also be used.
  • an adhesive viscosity of 500 - 1500 mpasec, nozzles of 0.2 to 0.35 mm in diameter and an application pressure of between 20 and 60 bar are particularly suitable.
  • the amount of adhesive applied should be of the order of 1 mg / mm 3 . With an adhesive density of 1 g / cm 3, this corresponds to a layer thickness of 1 mm. Higher layer thicknesses are harmless for the seal, but are less suitable due to the impairment of the appearance of the packaging.
