Description

Stackable packaging, in particular in the form of a folding sleeve, folding box, folding box or the like

The invention relates to a stackable packaging, in particular in the form of a folding sleeve, folding box, folding carton, erectable box, wrap-around packaging or the like, according to the preamble of claim 1.

Usually, objects, such as bottles in particular, are packed in packaging boxes in the form of folding sleeves and trays, folding boxes, folding cartons, erectable boxes or wrap-around packaging with a smooth base. In trays, the objects, such as cans, bottles and the like, are additionally held in place by a cover made of shrink film.

If the packaging has to be stored or transported in a stack, they have little mutual support due to the smooth floors, so that they can easily shift against each other, especially during road transport.

In addition, when stacked on top of each other, the packaging is subjected to high pressure loads, which can lead to undesirable deformation of the packaging body, especially if the packaged items do not completely fill the packaging between the base and the lid. This also limits the achievable stacking height.

The invention is based on the object of designing stackable packaging according to the preamble of claim 1, which is particularly suitable for packaging bottles and similarly shaped objects, in a simple manner so that the packaging, when stacked on top of one another, including the bottles and similarly shaped objects packed therein, on the one hand find a secure mutual hold against lateral displacement or slipping, but on the other hand also have improved stackability without there being any fear of deformation of the packaging body due to the pressure loads occurring in the stack.

This object is achieved according to the invention in that the bottom of the packaging has a central stacking opening below each object in such a way that when the packaging is stacked on top of one another, the objects in an upper packaging each rest either directly or indirectly on the heads or closure parts of the objects in a packaging located below, which engage in the stacking openings on the bottom.

In a preferred embodiment of the invention, the stacking openings can have a slightly larger diameter or cross-section than the heads or closure parts of the objects in a package located underneath, such that the heads or closure parts completely penetrate the stacking openings. In this case, the packaged objects are directly on top of each other. This embodiment can be used with

Advantageously used in packaging where the packaged goods or the objects or bottles contained therein are secured against slipping out of the packaging body.

In a modified embodiment, such a stackable packaging can also be designed in such a way that the heads or closure parts only protrude into a matching stacking opening on a lower base part of the upper packaging and are supported on a base part above it without a stacking opening, so that the heads or closure parts do not completely penetrate the base of the upper packaging, but only partially. In this case, the packaged objects do not stand directly on top of one another, but are separated from one another by the flap on the base of the packaging without a stacking opening, as it were, only as an intermediate layer. This embodiment is particularly suitable for trays that are open at the top and in which the packaged objects are not secured in their upper part against slipping out.

However, another preferred embodiment is also particularly suitable for such a simplified stackable packaging according to the invention, in which the heads or closure parts of the objects are secured in a smaller stack opening on the bottom of the upper packaging without being punctured and the bottom of the packaging around the stack opening is pressed towards the bottom of the objects or the packaged goods in such a way that the latter at least in places stands on the bottom of the packaging or the bottom of the packaging supports the objects or the packaged goods around the stack opening. This embodiment is of course suitable for trays that are open at the top as well as for packaging bodies in which the packaged goods are secured against slipping out upwards.

·

Particularly advantageous developments of the stackable packaging according to the invention are characterized in claims 5 to 13.

The packaging according to the invention thus ensures in a simple manner, through the stacking openings on the bottom of the packaging body, a positive locking of the bottle or container heads of the bottles or containers stacked underneath, so that the packaging units are perfectly secured against slipping and safely maintain their vertical arrangement one above the other in the stack even under unfavorable transport or storage conditions. The objects arranged in the packaging can either be secured with their heads or closure parts only in the stacking openings and abut against a bottom flap on the packaging body located above it, which is located as an intermediate layer between the container head or closure part and the bottom of a packaging object or container located above it. If the stacking openings have a smaller cross-section, the container heads or closure parts can also press the packaging material against the bottom of the objects or containers located above it.

However, the container heads or closure parts can also positively penetrate the stacking openings in the base of the packaging body above and, if necessary, protrude into the hollow base of the bottle or container above.

This ensures that the packaging is perfectly secured against mutual displacement or slipping both during transport and during storage, with a particularly simple and functional design of the packaging body.

The invention thus creates a secure composite of several packaging units stacked on top of each other without additional material expenditure.

Another particularly advantageous feature is that when stacked on top of one another, the packaging does not have to bear the high pressure load from the packaging above it, but rather that the items arranged in the packaging support one another and thus form a self-supporting packaged item, which enables a considerably higher stack height than with conventional packaging.

Another advantage is a positive upper locking of the bottle or container necks by punching out the sides of the lid flaps or edge bars. The free-standing bottle or container necks also result in a reduction in the "box height".

Preferred embodiments of the invention are shown schematically in the drawing.

The stackable packaging 1 shown is designed, for example, in the form of a folding sleeve, folding box, folding carton, erectable box, wrap-around packaging or the like and is used in each case for packaging a number of objects 2, such as in particular bottles or containers, which stand next to one another in rows on the base 3 of the packaging 1 and are enclosed by a wall 4 protruding from it.

As can be seen in particular in the two schematic diagrams of Fig. 1 and Fig. 2a, the base 3 of the packaging 1 has a central stacking opening 5 below each object 2 in such a way that when the packaging 1 is stacked on top of one another, the objects 2 in an upper packaging 1 each sit directly on the heads or closure parts 6 of the objects in a packaging located below, which protrude into the corresponding openings 5 on the base 3.

In the case of bottles with a curved bottom 7, the bottles, in a packaging located underneath, as shown in Fig. 1, can reach with their head, cork or other closure part 6 through the stacking opening 5 in the bottom 3 of the upper packaging 1 up to the curvature 8 on the bottle bottom 7.

The packaged objects 2 or bottles support each other in this way. The packaging boxes are subjected to only a small amount of pressure or not at all, and in addition, all the packaging 1 stacked on top of each other is fixed to one another in a way that prevents it from slipping.

For bottles or containers with a flat bottom 7, the bottles or containers underneath grip, as shown in Fig. 2a

shown, also with their head, closure part 6 or the like in the stacking openings 5 on the base 3 of the packaging 1 located above and support the container located above directly on its flat base 7, so that here too the safety requirements against displacement and pressure stress on the packaging are perfectly met. The objects or the packaged goods 2 can have a protruding collar 6a on its head or closure part 6, on which the base 3 of the upper packaging 1 rests around the stacking opening 5.

Likewise, the upper packaging 1 with the objects or the packaged goods 2 contained therein can be supported on the heads or closure parts 6 of the objects or the packaged goods 2 in a packaging 1 located underneath in the form shown in Fig. 2b. The heads or closure parts 6 only protrude into a matching stacking opening 5 on a lower base part of the upper packaging 1 and are supported on a flap located above it, which does not have a stacking opening 5, so that the head or closure part 6 does not completely penetrate the base 3 of the upper packaging 1, but only partially, whereby the packaged goods 2 in the packages stacked on top of each other also support each other.

In the further simplified embodiment shown in Fig. 2c, the packaging 1 has only stacking openings 5 of smaller cross-section on its base 3, so that the heads or closure parts 6 of the objects or of the packaged goods 2 in a packaging 1 located underneath, which are larger in comparison, press the packaging material on the base 3 around the stacking opening 5 against the base of an object 2 located above it, and in this way a positive support and securing of the packaged goods in the packages stacked on top of one another is also ensured.

All of the packaging 1 shown are essentially cuboid-shaped. The embodiments of Fig. 1, 3, 4 and 5 each have inward-facing edge webs or lid flaps 9 with edge cutouts 10 in the upper area of the packaged objects 2 for a positive lateral holding of the objects 2 below the head or closure part 6.

The inwardly directed lid flaps 9 engage with their edge cutouts 10 on bottles or containers with a neck 11 that is tapered or stepped or similarly offset from the bottle or container body in an area above the thicker bottle or container body 12, so that the bottles or similar containers on the one hand find a firm mutual hold and on the other hand are also perfectly secured against tipping sideways.

As can be seen in detail in Fig. 3c, 4c, 5c and 6c, the packaging blank 20 in these embodiments consists of a material web 21 folded several times at the corner areas of the packaging body with at least four foldable base parts 22a, 22b, 22c, 22d, which at least partially overlap one another when the packaging 1 is in the upright position and have the stacking openings 5 in rows next to one another in such a way that the stacking openings 5 of adjacent base parts in the overlap area at the corners of the packaging are each concentrically aligned with one another.

The overlaps on the bottom provide additional reinforcement to the packaging 1, especially in the sensitive and stressed corner areas.

While the packaging 1 of Fig. 3 and 4 is designed to hold a total of six bottles in two rows of three next to each other, the packaging 1 of Fig. 5,

As shown in the bottom view of Fig. 5a and the top view of Fig. 5b, it is designed to hold a total of twelve bottles in three rows of four next to each other.

The packaging blank 20 of this stackable packaging is therefore provided with at least one further row of stacking openings 5a or edge cutouts on the foldable base parts 22a, 22b, 22c, 22d for receiving the three rows of packaging items 2 or bottles according to Fig. 5c.

The additional row of stacking openings 5a or edge cutouts is formed on the outer edge of the base parts 22a, 22b, 22c, 22d as a semicircular cutout to be supplemented by an opposite cutout when the packaging is in the upright position.

If required, such packaging 1 can also be enlarged for additional rows of bottles either in the width or length of the packaging blank 20.

In the packaging 1 of Fig. 1, 3, 4 and 5, the base parts 22a, 22b, 22c, 22d on the other side of the packaging blank 20 are opposite foldable lid flaps 9, which each have a row of edge cutouts 10 on their longitudinal edge for a positive holding of the packaged objects 2 in their upper area.

The packaging 1 can either be cuboid-shaped, as shown in Fig. 4, 5 and 7, or, as the embodiments of Fig. 3 and Fig. 6 show, have bevelled or broken vertical corners 1a such that the packaging body has an overall octagonal shape.

- 12 -

In this case, round objects 2, such as bottles and similar containers in particular, are additionally secured and supported in the corner areas by the packaging wall being placed directly against the bottle body.

In the further embodiment of Fig. 7, in which the packaging 1 is designed as a so-called tray, the packaging blank 20a consists of a rectangular base 3 with several rows of smaller stacking openings 5 arranged next to one another and a total of four edge flaps 24a, 24b, 24c, 24d that can be set up and firmly connected to one another. In this case, the heads or closure parts 6 cannot pierce the smaller stacking openings, but rather press the packaging base 3 upwards around the stacking openings 5, as already described for Fig. 2c, so that here too the packages stacked on top of one another find secure mutual support in the stack.

In such packaging or trays, the packaged objects 2 are expediently held in place by a shrink film (not shown) or another suitable wrapping, whereby the film or wrapping is drawn in between the bottle or container necks or lids so far that they engage in the openings 5 on the bottom 3 of the packaging 1 located above them and can thus fulfill their securing function perfectly.

In all embodiments shown, the packaging blank 20, 20a can also consist of cardboard, corrugated cardboard, plastic or another suitable dimensionally stable packaging material.
