Description

of the invention: "Iris-Jaatschachtel"

The subject of the invention is a folding box, the cohesion of its opening and its closure by a novel orism-like ' Wrinkling is effected.

This "iris shutter ¹ comes with a special Palt en svs tem that on the blank of the folding box vorzurichten 1st to" * Registry.

Its possible application "is limited to those designs whose layout forms an equilateral and equiangular polygon _9, ie an equilateral triangle, a square, an equilateral and equiangular five-, six-, seven-, eight" _s Heun-U ₉ S ₀ W ₉ ] IiCkS ₀

All inner lines represent the prepared column broth _f and the full lines indicate those fold breaks, directed outwards when folded, which form the outer edges of the landings «

The dashed lines identify those folds whose outer edges are directed towards the inside of the folding box and cause the iris-like locking effect of this fold system when folded *

The dotted line indicates

the inward fold break of one hand strip with the double edge strip on the other side the cohesion the walls forms.

Closing position the bulge located over the iris folds upper edge portions question-mark-like manner outwardly out _s so that their inner sides are visible. Upon further folding the iris folding pivot with simultaneous reduction in the Kittel point a _s by mutually intersecting overlap sum portion, and wherein the located over the iris folds upper hand parts to lie with their inner sides outwardly upwardly kommenβ

At the same time, the nested marginal strips of the walls cling to each other, read at right angles together with the folds of the iris and thus hold the tandings of the box together.

The in tip 1. ^ · eTebene blank and the Fait system contained therein relate to an -'Iris-folded carton ", the" bottom and top sides are formed by the iris shutter. Fig. ^J 3. shows the completely folded Iris-FaIt box in perspective top view, the hatched parts

identify those parts of the iris closure whose inside is facing upwards in the closure position »

The. Direction of the iris folds, either to the right or to the left, determines the direction in which the folds insert when they close. This closure is easy to pull if it is done simultaneously for all iris folds, which is effected in the simplest way by placing the cupped hand on the open upper back and turning it slightly in the direction of the iris cleft. The opening of the iris is just as easy by pulling apart two opposite fold tips. The Iris VersohluS can be opened and closed again and again in this way »

As shown at the beginning, the iris closure can be used for all polygonal ones. Equilateral and equiangular plan figures application Find. Each of the possible ground plan figures requires the mathematically resulting angular position of the iris folds. Fig. 4. gives a graphic representation of the degrees of angularity of the iris fold for the most important plan figures of the regular . "Triangle, square up to the regular IJeunec.k.

FIGS. 5 to 10 of the drawings show top views of exemplary embodiments of the iris shutter from a triangle to an octagon

The iris closure can also be used without the simultaneous sealing of the walls Bracketing, can easily be done in a familiar way. Gluing or stapling can be replaced.

For example, the lower part of a folding box can be designed according to one of the known constructions and only the upper part can be designed as an iris closure. Fig ₉ II shows such a combination.

The in · Fig. 4. The representation of the angle of the iris folds given in the attached drawings for the various plan figures / relate to the mutual intersection of these folds in the center of the plan figures and the plane of the base of these iris folds _a By enlarging the angle of this iris - Folds can move their point of intersection to a correspondingly higher level - / earth. This results in a fora change in the sense of a more or less roof-like design of the entire iris closure - on the other hand, this results in the utilization of an increased closure effect of the so P -shaped iris closure, if you exert pressure from above on the iris spine, the spine, which is placed a little higher, jumps down by the same amount and instead of the hitherto roof-like bulge forms a trough-like bulge Depression, which forms a larger elastic lower part of the opening of the breech stood in contrast to the upper layer of this locking point, "Figures 12 and 13 of the drawings represent exemplary embodiments with such raised points of intersection.
