Portable cardboard box to hold juxtaposed , preferably cylindrical containers, such as bottles.

The invention relates to a portable folding carton for receiving closely lined up, preferably cylindrical 'Containers, such as bottles, which can be produced from a rectangular blank, after firmly adhering overlap of two opposite end edges can be folded flat and, provided with parallel main crease lines, for The receptacle can be opened in the form of an elongated hollow shaft, as well as with lateral supports is equipped for the received container.

Folding boxes of this type allow very space-saving storage in the prefabricated state, should if necessary Can be opened as quickly and reliably as possible and then a mostly even number of cylindrical ones Pick up containers, cans or bottles. You then have a light and hand-wrought, as well as sufficiently strong

bil transport box for the goods picked up in retail sale .

The previously known folding boxes of this type should take the shape of the hollow shaft when unfolding as possible without additional Take up work and loss of time and are therefore prefabricated as far as possible. Depending on the material used, the two firmly adhering overlapping end edges are glued together * in other cases chemically or thermally welded. Naturally, a rectangular one that is as simple as possible is desirable Cut for the least amount of manufacturing effort.

If necessary, container ¹ is also provided with lateral supports so that the unfolded cardboard box does not slip out and is reliably held in place when it is carried away. If it is a question of bottles, then these should be supported on the bottle necks if possible. Particularly important is the requirement to be able to open and unfold the individual boxes by machine, as quickly as possible and without disruption.

In general, one has packaging machines for this purpose which work with suction nozzles and thereby determine Zones of the flat-folded cardboard can hold. It is well known that the previously known Folding boxes either too complicated to cut, too awkward to handle and not even desirable simple means to unfold. The object of the present invention is to eliminate these disadvantages.

Basically, the simplest shape is obtained when such packaging boxes have a rectangular cross-section.

In this case, however, the folding for the supply layer cannot be carried out symmetrically and also opening it is therefore much more laborious than with a symmetrical folding shape. Therefore are also Folding boxes with a hexagonal cross-section known, their symmetrically bent side walls result in a folding shape in which three surfaces are the same on three Surfaces.

However, there is a problem with such a symmetrical folding shape that when pulling out the folded Cardboard boxes are also given the correct shape to unfold. Even if you have the necessary Increased machine effort and the boxes held on their underside with suction nozzles exactly in a horizontal position Direction squeezes, it can happen that instead of

Enteine s hollow shaft is in the shape of a tea channel. the The consequences of this are significant operational disruptions and loss of time, as well as the need for such a machine to be monitored by auxiliary staff during operation. aside from that

2G, care must be taken that the cardboard parts provided for lateral support do not fold out prematurely. Such lateral support parts not only increase the necessary cut, but they also have the disadvantage that the crease with which they hang on the cut represents a particularly weak zone of material. Here the Γ material can tear first when overloaded. A ".3or5em can happen in an undesirable way if ^r lev unfolded cardboard boxes filled with relative .. ^ -" !.

The object of the present invention is to do this too To eliminate the disadvantage of creating a light, symmetrical folding box with the simplest of cuts and at the same time both storage and handling when unfolding To simplify as much as possible, so make sure that you have the desired hollow shaft shape and no gutter received. In addition, when inserting the container, when "closing the filled carton and" easy and quick handling when carried and the insertion position the containers or bottles picked up must be properly secured.

A portable folding carton that meets all of these requirements and with a rectangular carton blank for production, Storage and use gives the most favorable conditions as well as also the problem of Lateral support solves much more easily and practically than before, is produced according to the invention in such a way that that the one main surface of the flat folded cardboard box through at least one recess interrupted, through which the opposite main surface for opening the box can be reliably detected and is to be pushed away. It is particularly practical if, for this purpose, preferably two recesses symmetrically in the surface in question, which can be retained by suction, and are dimensioned so that through each recess a pressure finger with a length which is at least sufficient to initiate the unfolding can be pushed in through it is. Man., So brings either a simple compressed air flow or two into the interior of the folded Finger gripping cardboard boxes the correct unfolding process comes about.

Another advantage of the folding box is the possibility of different polygonal cross-sections if necessary

To be able to realize what allows any design of the packaging space and at the same time an appealing design, for example for certain bottle formats. For this purpose, in a further development of the invention it is suggested that the horizontal with the fold folding base plate and its normally parallel cover plate are connected together by zwei'Seitenwände the same hollow shaft length provided in parallel to their main central crease lines nor of a further ä ren Khicklinie and thereby are composed of three flat surface sections inclined towards each other as desired.

The problem of the required on both sides can now be solved in an extremely practical and surprisingly simple manner Loosen flaps or flaps. This is achieved with the smallest cut and without impairing the unfolding process according to the invention "in that the lateral support of the container in the elongated hollow shaft opened cardboard box on both sides each made directly from the rectangular cardboard blank and through

between parallel slots close to the edge in the same main plane, ( preferably in the cover plate, one edge strip each formed and each edge strip in a vertical position when the box is opened Is bent inward direction and, at the end two inwardly folded support triangles forming the recorded Holds container reliably on the open hollow shaft.

One

A further embodiment of the folding carton according to the invention is achieved specifically for receiving a number of, for example, 2x3 bottles with pressed crown closures, which are placed close together, in that the width of the parallel slots near the edge in the cover plate is

measure is that the crown locks on the outside If the edge strips are bent vertically inwards, the bottles fit into the parallel slots from the edge strip underneath and when lifting the cardboard on its Deekplatte, preferably by means of two gripping holes cut into it, due to the deformation of the cover plate that begins are additionally supported by the bent edge strips. The one on each such retaining strip when bending inwards The resulting support triangles lie exactly in the desired support direction and can also be used with fold reliably with one handle.

Another very practical improvement results in the simplest way already when punching the rectangular blank. So you can get a particularly reliable recording cylindrical container or bottles obtained in that in the vicinity of the bottom plate in the adjacent surface sections For each individual container, curved slots are cut to match the circumference and bent to deia Slit in the upward direction radiating apart from each other relief slots are provided, the one protruding from the respective container over the surface section Allow bulge, which in turn hugs the outermost ring edge of the container elastically. In addition only the punching machine in question must be designed so that in the base plate to facilitate a elastic deformation when the container is pushed in, slots are cut close to the open edges preferably proceed in an angled form from the adjacent curved slots.

30 "The mentioned technical advantages of the portable folding carton according to the invention are explained in more detail for an embodiment example. Show in it:

Fig. 1 shows the handy and reliably secured packaging of a total of six in two rows close to one another standing bottles B in a portable folding carton, which can be opened with two simple gripping holes 12 to 10 ' quem can be carried and with the simplest rectangular cardboard blank folded completely flat and stored x can earth.

Fig. 2 is the top plan view of this carton in the collapsed condition, viewed from below. The overlap zone the base plate 2 is indicated in the illustration according to FIG. 2 by a horizontal center line. Then you can Provide two short tuck-in flaps 1 that protrude at one end edge and into corresponding cut slots fit in at the other end edge. However, you can also without these tabs 1 by other means a reliable Achieve gluing or welding of the material in question. Then the blank is actually rectangular, possible with all of the punchings to be explained in more detail, alco without cutting waste or any cumbersome Lateral flaps.

The completely flat position of the folded cardboard according to Fig. 2 therefore only requires the space for twice the cardboard thickness and is also completely symmetrical to the glued overlap zone. For this purpose, the side walls are necessarily halved by the kink line 5 and additionally divided by a second kink line 6. If all sides are completely the same length, the width of the surfaces can be chosen in any way. Only the side surface portions j5, 25a and J5B should of course both sides have the same size and for the folding of the fold line 5 must be arranged so that the bottom plate 2 bg with the adjacent to each side surface portions 3 and 3> ^e ~ "exactly the same width occupies, like the width of the cover plate 4 with the two surface sections j5a. The entire receiving space should also be so large that it encloses the enclosed containers B or bottles as tightly as possible and can thus also hold them free of movement. Very practical with this exemplary embodiment according to FIG. 1 is the extension of the flat base plate 2 in the form of small bulges, which are effectively supplemented by corresponding slots 8 and incisions 9 in the adjacent surface section Jb, because this allows the material to cling elastically to the outermost ring edges of the container B in the form of these protruding bulges »

The folding lines 5 can of course also be arranged exactly in the middle of the side walls, so that the hexagonal cross section of the shaft space is obtained. The additional kink lines 6 here result in an octagonal JiO cross-section and other polygonal cross-sections can also be obtained in the same way by further kink lines. The only requirement that must be met for practical folding is the aforesaid arrangement

909838/0199

the crease lines 5 for flat folding.

FIG. 5 shows, in schematic form, the very simple and, according to the invention, also maintenance-free, quick opening process without any disruption due to the two recesses 7. Due to their own weight, they reliably flatten themselves. As you can see, two short supporting edges on each side of the magazine M are sufficient. For this purpose only a suction nozzle V needs to be attached in the middle of the base plate 2 of the lowest folding box. The base plate 2 can then be pulled off with little force. Two pressure fingers D pointing parallel to one another reach through the recesses 7 and press from the inside against the cover plate 4, which lifts upwards parallel to the base plate 2. The process is extremely simple, trouble-free and also possible without deforming the cardboard material because the two folding lines 5 approach one another. If the one held by the suction nozzle V is lowered. Folding cardboard down into a corresponding mold space A, then the cross-sectional shape of the elongated hollow shaft resulting from the rectangular blank is automatically forced, namely precisely the bottom plate and the cover plate 4 horizontally and parallel to each other, the lower surface strip Jb into the through the mold space A given angular position and consequently also inevitably the angular position of the surface sections 3 and jib. because of the remaining width.

In this exemplary embodiment, the individual containers B are beverage bottles and fit close together in two rows of three bottles each

bulges of the lower surface section JPo formed in the form of cuts 8, the relief slits 9 with the radial arrangement shown in FIG. A rattling of the received container during transport is avoided.

According to the invention, the essential lateral support of the container B is the two lateral edge strips 10, which arise automatically when the cover plate 4 is punched out. The parallel slots required for this, unspecified, also offer the advantage that the known crown closures of beverage bottles fit exactly into them, i.e. the edge strips 10, which are bent vertically inward and downward, each grasp the closures of the outside bottles B, and can also lie tightly against the bottle necks . The two supporting triangles H ₃ which are formed and which are folded inwards are very advantageous. Reliable support in the desired direction is obtained in just a few simple steps / the support triangles J5 are, on the other hand, like this

small that there is a particularly high buckling resistance even with cardboard box thickness. The creases indicated by dashed lines in FIG. 1 can be pre-embossed when the cardboard blank is punched out. So the effort is very easy.

The containers B are only pushed into the opened hollow shaft, then the two edge strips 10 folded inwards and used for carrying two gripping holes 12. Due to the transport weight, the Slightly deform cover plate 4 and thereby provide additional support for the bottles standing on the edge,

because now each edge strip 10 not only engages under the crown locks, but also partially supports the load weight. With simple and convenient handling, the load on the base plate 2 is therefore also reduced.

In order to avoid that the cardboard material is stressed too much when the bottles are inserted, before the bottles get into their insertion spaces on the seat straps 8, further slots can be provided in the blank. So can | the surface section 3a still received parallel slots, which are designed appropriately. An example of this is shown in FIG. 1 with a more detailed designation. Even if the dimensions of the bottles B are a little too large, the material is so much relieved that the inwardly folded edge strips 10 do not open by themselves via their support triangles 11.

In addition, the slots 13 shown in the base plate 2 according to FIG. 2, which enable the cardboard to be made free of cracks in the particularly endangered edge zone, are also very advantageous. The arrangement and shape of these slots 13 can be seen from the drawing. The slots 8 correspond to the bottles of curvature and to avoid risk of cracking on both sides off in the opposite direction (curved. All the slots 8, 9 j 13, etc. can be prepared by punching out of cardboard material, or even by simple cuts. Is obtained in this way in all Desired areas of the folding carton according to the invention the necessary elasticity to achieve rapid filling, reliable fastening and carrying of the individual containers received without the risk of cracking. Bottles and cylindrical containers, such as cans, are described in the description of the exemplary embodiment. In the same way, other container formats and, of course, other groupings of the containers to be transported can also be

speaking modification of the proportions with the inventive Pack the carton.

In any case, the present invention enables the simplest cutting without material waste, one complete flat storage in folded form, whereby the folding boxes are already completely prefabricated. Disturbing side parts and edge flaps are completely absent, opening is easy and trouble-free possible, primarily through the recesses 7 according to the invention in the base plate. These can even If necessary, they can be replaced by the gripping holes in the cover plate, for which purpose then in the reverse stacking position the unfolding takes place. The known arrangement of suction nozzles on the outside is supplemented according to the invention by the pressure made possible in the opposite direction, either by compressed air or by Pressure finger. The machine effort for this is conceivable small and the whole construction extremely practical. The features of the invention, recesses to open, any polygonal cross-section without protruding edge parts, reliable support through pre-cut edge strips, tight holding of the receptacles in elastic locking spaces and the most expedient stress relief through indentations in any exemplary embodiment of the Realize folding boxes according to the invention in a variety of ways and in every practical case of need.
