FOLDING BOX

There are boxes with interior fittings to hold rod-shaped, fragile goods such as ampoules and glass cylinders in particular known. In such boxes, the desired strength can only be achieved with a correspondingly large amount of material and labor can be obtained as the interior decoration to achieve a corresponding torsional stiffness generally has to be glued into the box interior.

The invention provides that the box body is formed from a single cardboard blank and a stable hollow body is formed by folding and creasing without the use of adhesive. Assembly is done by folding of the longitudinal sides, which are brought to nearly twice the width and grooved approximately half High or scratched., - wherein the at the end faces appended by 90 degrees bent tabs are surrounded by the folded-in longitudinal sides. The special strength is achieved in that the corrugated cardboard strip intended to receive the packaged goods is inserted into the box body with its bottom slightly protruding on both long sides so that the inwardly folded long sides of the box body prevent the corrugated cardboard strip from being removed. The folded long sides form a lock by means of which the said bottom of the cardboard strip is held in place. In this way it is achieved that the box body, assembled without glue, is in the shape given by appropriate folding and kinking.

hen remains and the corrugated cardboard strip cannot be moved in its position is being held. The corrugated cardboard strip is in turn one Packing insert with any number of individual compartments, in which the inserted goods are held firmly and unbreakable, as the insertion openings are tapered.

The stability achieved in this way corresponds to the requirements packaging designed to contain fragile objects. In addition, the box according to the invention points to the decisive one Set up double walls. The front sides of the box can Be designed in such a way that double walls ehenfails can be folded inwards or with a corresponding lengthening extend over the entire surface of the box and with the appropriate Form a box lid design. This box body can be used in conjunction with a sliding sleeve or with a Slip-on lids can be made into a sliding box or a slip-lid box.

In this way a box is obtained similar to the one in the packaging Requirements for ampoules and other fragile goods in terms of cost-effectiveness, protection and resistance is fair in a special way.

Further features of the invention emerge from the following Description referring to the drawing.

The drawing shows an example of the invention in schematic form Way presented. Show it·:

FIG. 1 shows the blank of a piece of cardboard forming the box body ,

FIG. 2 shows a diagrammatic representation of the corrugated cardboard strip to be inserted into the box body,

Figure J shows a section through the box body for illustration the holding function of the inwardly folded side walls,

Figure 4 is a view of the fully assembled box.

The cardboard blank of the box body consists of a punched or cut-out area with a recess at the 4 corners, A notches and only three edges. The spatula bottom is formed by the surface 1, the side walls 2, 3-4 and 5 are folded up by JO degrees, the flaps 6 are before

bent up by 90 degrees and placed on the inside on the long sides 3 and 5, that "when folding in the widened side walls 7, the flaps be sewn in place.

¥ χ: πΐ now the corrugated cardboard strip Figure 2, consisting of the parts 9 and 10, the dimensions of which correspond to the interior of the above-described Corresponding to the assembled box body, inserted into it, the bottom 10 of the corrugated cardboard strip engages, which protrudes a little on the two long sides, under the two inwardly folded sides 7 of the box body and is thereby held immovably in its position. Simultaneously a high torsional stiffness is achieved as a result.

The extended end faces 8 are over the opening of the box body and cover them completely. If the elongated end faces 8 are shaped differently, they can also be shaped according to are folded in on the inside and are then used to reinforce the front sides 2 and 4 · The box body obtained in this way can be achieved by a Paper strips are sealed and is thus a finished package. However, this box body obtained in this way is preferably inserted into a sliding sleeve of a known type and as a sliding box used or one provides the box body with a slip lid, whereby a slip lid box is obtained will.
