Description

The present invention relates to a folding box according to the preamble of claim 1 (US-A-5 125 565).

In the textile departments of department stores and department stores basically the problem that hangers on which the Goods are hung for sale after selling the corresponding one Item of clothing back to their place of origin must be returned. For this purpose, so far the hangers no longer needed indiscriminately in one Containers, such as a roll container, placed and on returned to their place of origin. Such an approach However, due to the associated high transport capacities unsatisfactory.

It is the problem underlying the present invention (Task) to create a container that and time-saving transport of hangers and remains undamaged even after repeated use.

This problem is solved by using a folding box the features of claim 1.

Due to the triangular cross-sectional shape of the invention Folding boxes can be stacked in this hanger, so that they save space on the one hand and on the other hand are safely stored in the box. Because of the triangular shape is the one required for the packaging of hangers Space minimized because of this cross-sectional shape of the box the outer contour of the hangers corresponds. With others Words the clothes hangers are placed in the box, that the hook and the two outer ends of the bracket each in one corner of the box. Here you can due to the triangular shape also hangers with slightly different Shape well protected in this folding box be accommodated. Especially when using hangers straighten with the cross-sectional shape of a double T. the hangers due to the triangular shape in the box so that the individual brackets their double-T profiles nest "into each other. This saves a lot of space achieved.

Since the bottom and lid can also be closed with a Velcro fastener are, the folding box according to the invention quick and easy to unfold or fold without a time-consuming kinking or folding of the folding elements or any folding closures would be required. At the same time ensured by the Velcro that the invention Folded cardboard undamaged even after multiple use remains. Finally, the one provided according to the invention serves Velcro also fastens to the bottom of the folding box secure against unintentional opening. This last one Aspect is important in that that with hangers filled folding carton can assume a considerable weight.

In this embodiment there is an extraordinary resilient connection of the Velcro the folding element, since the Velcro fastener opens frequently and closing is not torn off, but the tensile forces distribute on the front and back of the folding element.

Due to the special shape and the damage-free Resealability of the folding box according to the invention can be reused many times before it becomes one Recycling must be fed. Are basically Cardboard products are ecologically usable, i.e. she can be easily disposed of and recycled become. Cardboard boxes are for reuse but not very suitable, because after one or two Use lose their strength and shape and in particular can no longer be closed satisfactorily can.

The folding carton according to the invention can in particular a major improvement in national transport of transport capacities. So you can using conventional transport boxes in one Trucks load about 70,000 hangers, whereas with the invention Folding carton 120,000 hangers can be transported. Because hangers either after their use in sales sold as used goods or to the hanger manufacturer have to be recycled for recycling, play regional and especially transregional transport capacities an important role.

Advantageous embodiments of the invention are in the Subclaims, the description and the drawings described.

The strip can also be used with particularly high forces the Velcro fastener can be designed all around, by this, for example, by two slit-like Openings in the folding element is performed.

According to a further embodiment of the invention at least one hook strip and at least one eyelet strip of the closed Velcro, preferably essentially right angle, cross. In this embodiment on the one hand there is a good fastening of the respective Stripes on the folding elements. On the other hand, the Velcro when opening only in the "crossing area" tensile forces exposed so that the risk that the Hook strips or the complementary eyelet strips detaches the tensile forces occurring from the folding box. At the Closing the box is also due to the crossing Strip ensures that the complementary parts of the Velcro straps meet securely, even if the dimensional stability of the carton after frequent use should already have decreased somewhat.

A particularly stable closure results from the fact that a folding element provided two parallel strips are and at least one further folding element complementary strip is attached, which in the closed Condition essentially perpendicular to the first runs two stripes.

If the Velcro fastener with a water-soluble adhesive is attached to the folding box, there is a very good recyclability of the folding carton according to the invention. When the boxes are recycled, they will be usually first soaked in a bath, taking off then according to the invention the water-soluble adhesive dissolves and the Velcro in the bathroom floats on top. So can not only the cardboard material but also the Velcro fastener be recycled.

It when the cross-sectional shape of the Cardboard boxes an isosceles and right-angled triangle is. With this cross-sectional shape, there is the possibility to store two folding boxes so close together that whose respective hypotenuse surfaces lie against each other. At Such an arrangement results in the overall shape of a Cuboid with a square cross-section, which one Further transport of the filled folding boxes is very advantageous turns out. For example, in a conventional Lattice roll box more than twenty trained Stack the cardboard boxes so that all of them are in the mesh box existing space is used.

According to a further embodiment of the invention, lids can and bottom each have three folding elements, each are provided with a handle opening, the handle openings of the closed lid or the closed Floor. In this embodiment, Contrary to conventional folding boxes, which have the handle openings usually have on the side walls, one "three-layer" handle opening. If the folding box is about the height of a job, this can be with Help of the handle openings provided in the bottom and in the lid easy to transport without the folding box in the Area of the handle openings.

If a side wall of the folding box is a continuous and vertical folding line, the folding box can after opening the lid and the bottom fold, which is very much when returning the boxes is advantageous.

According to a further advantageous embodiment, at least a strip of Velcro on both sides a folding element attached, two free ends this strip together in an opening in the folding element are connected. By such an embodiment a higher resilience is achieved and with a corresponding wide formation of the strip no additional, parallel stripes on this folding element to be ordered.

a perspective view of a folding box according to the invention;

Fig. 2

a blank for the folding box of Fig. 1; and

Fig. 3

a side view of a trolley with several folding boxes according to FIG. 1st

The folding box shown in these figures has three Side walls 10, 12 and 14, the container wall 10 with the container wall 14 glued via a folded strip 15 (Fig. 2) is. The side walls 10, 12 and 14 are dimensioned so that that the cross section of the carton isosceles and forms a right triangle.

The lid of the folding box is by three folding elements 16, 18 and 20 formed, each with the side walls 10, 12th and 14 are integrally connected. In the same way is the Bottom of the folding box by three folding elements 22, 24 and 26 formed which is the same shape as the folding elements of the Have lid. In the folding elements of the lid and The bottom is a handle opening 28 (bottom) and 30 (Lid) provided, the handle openings 28 when closed Lid and the handle openings 30 when closed Align the floor with each other.

Used to close the bottom and the lid a Velcro fastener, the same in the bottom and in the lid is trained. Therefore, only the cover-side is shown below Velcro closure described.

The Velcro fastener arranged in the lid consists of a total of three strips 32, 34 and 36, strips 32 and 34 are the same, but the strip 36 is complementary is. In the present example, the strips 32 and 34 designed as a hook strip, whereas the strip 36 is designed as an eye strip. However, the arrangement can also be the other way around.

The two hook strips 32 and 34 are on the folding element 20 attached and guided around an edge of the folding element 20, which is formed by the handle opening 28. On the are not visible side of the folding element 20 in FIG. 1 the two strips 32 and 34 also attached. The eye strip 36 is on the folding element 16 parallel to the Handle opening 28 attached, whereas the two Strips 32 and 34 perpendicular to the handle opening 28 of the Folding element 20 run. This results in the closed Cover a strip arrangement in which the Eyelet strips 36 at least substantially at right angles crosses strips 32 and 34.

To attach strips 32, 34 and 36 is good for Recyclability uses a water-soluble adhesive.

To produce the folding carton according to the invention is only the fold strip 15 on the inside of the side wall 10 glued and the Velcro strips of the lid and of the floor are attached to the folding elements. On that the folding box can be closed by closing the bottom bring shape shown in Fig. 1. After filling the folding box with hangers, the folding element 18 and then the folding element 20 is closed. In connection thereupon the folding element 16 is folded over, so that its Strip 36 on the Velcro strips 32 and 34 of the Folding element 20 comes to rest. This is the folding box stably closed and can be easily transported are gripped by the handle openings 28 and 30 becomes.

After the folding box has been emptied, only the Velcro fasteners the lid and the bottom are opened, whereupon the folding box despite the glued folded strip 15 in an essentially flat shape can be brought by this on an intended fold line 38 (FIG. 2) is folded, which is placed parallel to the outer walls of the Boxes, i.e. vertical, runs.

According to a further, not shown embodiment of the Invention can be at least one strip of Velcro be attached on both sides of a folding element, wherein two free ends of this strip in an opening in the Folding element are interconnected. This opening can for example a square or rectangular punch be in the folding element. If an edge of this die cut is formed parallel to an edge of the handle opening, can the Velcro strip on the one hand around the Guide the handle opening and on both sides of the folding element stick on. On the other hand, the still free ends of this Strips in the cutout are glued together again become. This is a self-contained Velcro strip formed with very high resilience. Provided this Velcro strip is sufficiently wide no further need to be used on this folding element Stripes can be arranged. Unless the streak through the handle opening should be guided, can also be two Provide opposing punched-outs in the folding element, the free ends of the strip then in one of the the two cut-outs are glued together.

Fig. 3 shows a dolly seen from the side Is U-shaped and in which there are a total of thirteen Folding boxes according to FIG. 1 are. As can be seen well can the cartons due to their triangular cross-sectional shape very advantageous and space-saving in the trolley stack. Here, the folding boxes are partially superimposed with their hypotenuse surfaces so that overall the shape of a cuboid is created. Some of them Cardboard boxes with their catheter surfaces so that the trolley can be used well overall.
