Definitions

  • the present invention relates to a clamp closure according to the preamble of claim 1.
  • Containers in particular boxes with such closures, are increasingly being used by the packaging industry for storing a wide variety of substances, such as sugar, confectionery, liquids, etc.
  • Fig. 1 blank and fold lines for a four-wall clamp closure
  • Fig. 2 is a perspective view of an open four-wall clamp closure
  • FIG. 3 shows a perspective view of a closed four-walled clamping closure
  • 4 shows a plan view of a closed four-wall clamp closure
  • Fig. 5 cut and fold lines for a three-wall clamp closure.
  • FIG. 1 shows the blank and fold lines for a clamp closure of the type according to the invention together with the other parts of the box.
  • Bottom walls 3, side walls 2 and closing walls 1 of the box can be folded from a single sheet.
  • Suitable material for the sheet is, for example, cardboard, which is preferably coated on one or both sides with a thermoplastic material, or a plastic film.
  • the closing walls 1 each have the same rectangular shape and are connected to one another via side fold lines 11.
  • a folding strip 4 delimited by a side fold line 11 is connected to the closing wall 1 and side wall 2 adjoining the lateral boundary 11a.
  • a closing wall 1 borders in each case via a base fold line 14 on a corresponding side wall 2, which in turn is connected to a base wall part 3 via a base fold line 21.
  • An end face 12 forms the end of a closing wall 1 opposite a base fold line 14.
  • a closing fold line 13 begins on the same side of a base fold line 14, which runs at a predetermined angle to the side fold line 11 to the end face 12.
  • a closing fold line 13 can start from the left as well as from the right end of the corresponding base fold line 14. It is a prerequisite, of course, that the same end of the base fold line 14 is chosen for a single clamp closure. If the closing fold line 13 runs from bottom to top to the left, the closing rotation takes place to the right as usual.
  • the length of the front catheter 121 to the length of the base fold line 1 is in a ratio of at least 1: 2 and less than 1: 1, but preferably in a ratio of 3: 4.
  • the length of the base fold line 14 to the length of the side fold line 11 is in a ratio of approximately 1: 1 to approximately 1: 3, the closure being easier to open and close as the ratio increases.
  • the material from which the closure is made can then be thinner.
  • Figures 2 and 3 each show a perspective view of a folded and glued square box in the open or. closed state.
  • Figure 4 shows a top view of a closed box.
  • the reference numbers in FIGS. 2 to 4 correspond to those in FIG. 1. It can be seen in FIGS. 3 and 4 that a part of the closing walls 1 that exceeds the interior of the box takes the form of a pyramid that is upside down. Closure is achieved, for example, by pressure on at least two opposite edges formed by the side fold lines 11 or a torque acting on a plurality of closing walls 1. The closure is opened, for example, by evenly pulling outward on the portions of the closing walls 1 forming the pyramid mentioned.
  • An optionally closable bag made of elastic material can easily be inserted into such a box. Such bags are used, for example, as refill packs or for airtight storage of products.
  • the clamp closure can also be additionally closed, for example by a suitable pyramid-shaped plug.
  • FIG. 5 shows the cut and fold lines for a three-walled clamping closure, which can be used to close the triangular opening of a container of any shape.
  • the length of the front catheter 121 to the length of the base fold line 14 is in a ratio of at least 1: 2 and up to and with 1: 1, but preferably in a ratio of 3: 4.
  • the length of the base fold line 14 to the length of the side fold line 11 is in a ratio of approximately 1: 0.8 to approximately 1: 3, the closure being easier to open and close as the ratio increases.
  • the material from which the closure is made can then be thinner.
  • the side adhesive fold bar 4a serves to connect the closing walls 1.
  • the lower adhesive fold bar 4b serves to fasten the closure to the container opening.
  • the front side cathete 121 can have the same length as the base fold line 14, ie the closing fold line 13 forms the diagonal of a closing wall 1
  • the front end has an arc shape so that it does not coincide with the front catheter 121, which forms the straight line parallel to the base fold line 14 between the front end of the side fold line 11 and the closing fold line 13.
  • the section 122 between the arcuate end on the end face and the end face cathete is highlighted with hatching.

Abstract

L'invention concerne une fermeture sertie qui comprend trois ou quatre parois de fermeture (1) formées par pliage d'une feuille de matériau pliable, de préférence du carton enduit. Une paroi de fermeture (1) est reliée à la paroi latérale (2) par une ligne de pliage de base (14) et à la paroi de fermeture (1) adjacente, par une ligne de pliage latérale (11). Une ligne de pliage de fermeture (13) s'étend dans chaque paroi de fermeture (1), depuis un côté de la ligne de pliage de base (14) jusqu'à sa face avant (12). La ligne de pliage latérale (11), la ligne de pliage de fermeture (13) et la partie de la face avant (12) qui se trouve entre elles, forment un triangle dans lequel le rapport de la longueur de la partie mentionnée (121) de la face avant (12) à la longueur de la ligne de pliage de base (14) est compris au moins entre 1:2 à 1:1.
