Abstract

The blank (20) has in the region of its gripping openings (3; 9) support parts (1, 1', 2; 8) which can be bent in each case starting from an upper gripping edge (13'; 14') of the gripping openings, on the one hand, in the direction towards adjacent inside surfaces of the resulting top surfaces (5; 7) and, on the other hand, at least partially also upwards or at least obliquely upwards.

Description

The invention relates to a blank for packaging material made of cardboard or the like for forming a packaging body, in particular a multipack, for holding a number of containers, in particular bottles, with the design features according to the preamble of claim 1.

A packaging material blank of this type is already known. If, for example, a multipack is formed from this, which is equipped with a number of successively arranged containers, such as bottles with crown corks, then there is the resulting packaging body, which serves as a carrying pack and is relatively heavy due to its content the danger that then If a person carrying the packaging body squeezes the handle area formed by the two opposite handle openings too much, in particular due to the bottle weight and manual force, the packaging material tears in the area of the handle openings, particularly in the direction of the relatively nearby punched-out holes for the crown caps Bottles is coming.

Because the handle openings and the punched holes for the crown corks in the packaging material blank are relatively close to each other, when the packaging body is fully equipped, the upper bottle necks also lie quite close to the immediately adjacent handle edges of the handle openings, so that there is a risk of tearing when worn is favored in the handle area explained.

Under these circumstances, it can even happen in practice that when the part of the packaging located above the two handle openings is torn open, the contents of the packaging fall to the ground.

In view of the described facts, the present invention has for its object to provide a new and improved packaging material blank made of cardboard or the like. To form a packaging body and to form this blank in such a way that the as explained above, the state of the art Technically inherent disadvantages are avoided, in particular the grip area should be stabilized in such a way that at relatively a training the risk of tearing is practically completely avoided.

Starting from a packaging material blank with the features of the preamble of claim 1, this object is achieved according to the invention in that the packaging material blank has support parts in the region of its grip openings, each starting from an upper grip edge of the grip openings in the direction of adjacent inner surfaces the resulting roof surfaces and on the other hand can be at least partially bent upwards or at least diagonally upwards.

A particularly advantageous embodiment of the support parts provided in the area of the handle openings results from claim 2.

Further advantageous refinements of the packaging material blank according to the invention can be found in each of claims 3 to 22.

According to claim 14 can also be provided for the packaging material blank that in the transition areas between the upper part and the roof surfaces each punched out for the positive introduction of upper parts or edges of the containers, for. B. bottle caps are provided.

In this case, an extraordinarily favorable further development of the invention results in that the first and second side flaps are in the fully assembled packaging body iw are bent at right angles or approximately at right angles or diagonally upwards towards the inner surface of the upper part and that when the containers, in particular bottles, are then inserted into the packaging body, the upper parts or edges of these containers, in particular the crown caps of the bottles, on the first and the second side flaps lie, preferably tightly, and fix these side flaps in their respective final assembly position, in which the side flaps at least partially also come to bear against the inner surfaces of the roof surfaces, and possibly also on the inner surface of the upper part.

It is also extremely advantageous according to claim 16 if, during the final assembly of the resulting packaging body, the first and second side flaps due to exposure to the respective containers inserted directly adjacent to the packaging body, in particular the bottles, and in particular due to exposure to their upper parts, i . H. preferably due to the action of the crown corks, causing a quasi-automatic snap movement upwards towards the inner surface of the upper part, in order to finally fix the side flaps in their respective final assembly positions.

On account of these last-described configurations of the packaging material blank according to the invention, it is ensured that it is particularly simple in the course of the final assembly of the packaging body to be formed from this blank and the simultaneous loading with containers, in particular bottles The desired stabilization in the grip area of the resulting packaging body comes in a manner that is practically and automatically.

In summary, it can be stated that the packaging material blank according to the invention results in an extremely advantageous manner in the grip area of the resulting packaging body, a practically complete, mutual support of the parts formed there from the packaging material, so that in particular in cooperation with the punched caps introduced into the grip area such a good grip stabilization is achieved that even with relatively violent pressure exerted by the hand of a person carrying the packaging, tearing in the grip area can practically no longer occur.

The following description of the preferred exemplary embodiments illustrated in the accompanying drawings serves to explain the invention, its further features and advantages in more detail, wherein the same reference numerals designate the same components throughout.

1, for the sake of simplicity, only the section of a packaging material blank 20 consisting of an upper part 6 and a first roof surface 5 and a second roof surface 7 is shown, that is to say the large parts of this blank, in particular those which are located on the roof surfaces 5 and 7 each connecting first and second side surfaces 15 and 16 (see. Fig. 2 and 3) and further, from the side surfaces 15 and 16 each outgoing inclined surfaces 30 and 30 ', which serve as connecting parts to connectable bottom parts 31 and 31' (see FIG. 3) are not apparent from FIG. 1.

From FIG. 1, on the other hand, it can be seen that in the transition area between the upper part 6 and the adjoining roof surfaces 5 and 7 on both sides, a number of punched out mutually opposed punchings 17 is provided, which serve to accommodate crown caps in each case in the resulting packaging body Take bottles with a positive fit.

The distance between the two successive pairs of punchings 17 in the longitudinal direction of the upper part 6 is denoted by a in FIG. 1.

The first roof surface 5 is provided with a first handle opening 3 which can be obtained by punching out, while the second roof surface 7 has a second handle opening 9 which can also be produced by punching out in a quasi-symmetrical arrangement.

From Fig. 1 it can be seen that the parts to be punched out in the formation of the first handle opening 3 are still within the outline of this handle opening, while according to the illustration in Fig. 2 these parts to be punched out are already pressed out of the first handle opening 3. These parts to be punched out in the area of the first handle opening 3 are the support parts used to form an inner handle support, as will be explained in more detail below with reference to FIG. 2, which in the first handle opening 3 consists of a first side tab 1, a second side tab 1 'and a middle tab 2 exist and together form a surface which is equal to the punched surface of the first handle opening 3.

The middle flap 2 has an approximately trapezoidal outline shape, the first side flap 1 being connected via a first folding line 4 and the second side flap 1 'via a second folding line 4' to the middle flap 2. The base of the trapezoidal middle tab 2 is formed by a third fold line 13, via which the middle tab 2 is connected to the first roof surface 5. The two first and second side flaps 1 and 1 ', which are approximately half the area of the middle flap 2, are approximately trapezoidal, the first side flap 1 having an outline through a first side 10, a second Page 11 and a third side 12 is defined, while the second side flap 1 'is characterized in outline by a first side 10', a second side 11 'and a third side 12'.

The middle flap 2 also has a side 2 'opposite the third folding line 13, the continuations of which are each formed by the third side 12 of the first side flap 1 and the third side 12' of the second side flap 1 '.

The part to be punched out in the region of the first handle opening 3 thus has an outline which is defined by the pages 10, 11, 12, 2 ', 12', 11 'and 10'.

1 also shows, the first and second fold lines 4 and 4 'each form an angle α of approximately 75 ° with the third fold line 13.

Both the length of the second side 11 of the first side plate 1 and the length of the second side 11 'of the second side plate 1' are chosen so that they are each approximately equal to a width b of the upper part 6, the rest of its two long sides a fifth fold line 18 or a sixth fold line 19 is connected to the respectively adjacent first and second roof surfaces 5 and 7.

It is now further provided that the lengths of the first and third sides 10 and 12 in the first side plate 1 and in the same way the lengths of the first and third sides 10 'and 12' in the second side plate 1 'are approximately the same distance c, which is taken between the third fold line 13 and the fifth fold line 18.

If one now considers the second handle opening 9 provided on the second roof surface 7, it can be seen from FIG. 1 that in its opening area there is a punched-out part in the form of an approximately rectangular flap 8 which is connected to the fourth via a fourth folding line 14 second roof surface 7 is connected. This flap 8 also has a function as a support element in the formation of the inner handle support, as will be explained in more detail below. The flap 8 has in addition to the fourth crease line 14 opposite and parallel to this a side 8 ', which forms a free side of the flap 8 due to the punching process.

When forming the resulting packaging body 21 according to FIGS. 2 and 3 from the packaging material Blank 20 according to FIG. 1, the completely free first and second handle openings 3 and 9 are formed in that in the first handle opening 3, the middle tab 2 together with the hanging on this first and second side tabs 1 and 1 'around the third crease line 13th is bent, while at the second handle opening 9, the flap 8 there is bent around the fourth fold line 14. Because of this bending process, a first grip edge 13 'is formed in the area of the third fold line 13 and a second grip edge 14' in the area of the fourth fold line 14, a person carrying the finished packaging body 21 reaching through these two grip openings with their fingers, as a result of which the grip edges 13 'And 14' then get to rest on the fingers when lifting the packaging body 21. In the formation of the finished packaging body 21, as is partially shown in FIG. 2, the procedure is now as follows when viewed from the inside of the packaging material blank 20 - that first the two first and second side flaps 1 and 1 ' are bent upward at right angles along the first and second fold lines 4 and 4 ', that the associated middle flap 2 is then also bent vertically upward along the third fold line 13, so that now the two first and second side flaps 1 and 1' with their respective first sides 10 and 10 'come to rest on the inner surface of the first roof surface 5. If the upper part 6 is then bent along the fifth fold line 18 in the direction of the first and second side plates 1 and 1 ', then finally touch the respective second sides 11 and 11' of the first and second side plates 1 and 1 ' the inner surface of the upper part 6 facing them. This state that has now been reached can generally be seen from FIG. 2. The procedure now continues so that the second roof surface 7 is also bent along the sixth fold line 19, that is to say is also bent upward, while the flap 8 is also bent along the fourth fold line 14 at the same time. In the resulting configuration, this flap 8 then comes into direct, tight contact with the middle flap 2, the flap 8 preferably resting directly above the middle flap 2, as is not shown in the same way in FIG. 2 for reasons of clarity.

In any case, in the finished assembled packaging body 21, the respective second sides 11 and 11 'of the first and second side flaps 1 and 1' touch the inner surface of the upper part 6, and in the case of bottles used in the packaging body 21, their crown caps which are in the side flaps 1 and 1 'adjacent punchings 17 are included, bear directly against the first and second side plates 1 and 1' and consequently fix these side plates in their respective positions.

In the final configuration of the inside of the handle between the two opposing first and second, continuously exposed handle openings 3 and 9 are then the respective upper, first and second handle edges 13 'and 14' iw through the closely adjacent parts, ie middle tab 2 and flap 8, in connection with each other, preferred in ter way, this middle tab 2 and the flap 8 are glued together and form an iw parallel surface to the upper part 6 with practically twice the material thickness.

According to a modified embodiment of the invention shown in FIG. 4, an arrangement of support parts to be punched out can be provided in the two first and second grip openings 3 and 9 in a symmetrical manner, i. H. such that the support parts still remaining in the areas of the handle openings each consist of a central tab 40 or 44 and two first and second side tabs 41 and 42 or 45 and 46 adjoining them on both sides, the respective central tab 40 or 44 is connected to the first roof surface 5 or to the second roof surface 7 via the third folding line 13 or the fourth folding line 14.

The middle tabs 40 and 44 are each approximately trapezoidal and arranged so that the third fold line 13 form a base side of the middle tab 40 and the fourth fold line 14 form a base side of the middle tab 44. In the area of the first handle opening 3 are the first and second side straps 41 and 42 and in a corresponding manner in the area of the second handle opening 9, the first and second side straps 45 and 46 are each via first and second folding lines 43 and 43 'with the respectively assigned middle tab 40 or 44 connected.

There is now the possibility that, on the one hand, in the area of the first handle opening 3 middle tab 40 and the associated first and second side tabs 41 and 42 together form an area which is iw the same size as the punched area of the first handle opening 3, and that on the other hand also in the area of the second handle opening 9 the middle tab 44 there together with the first and second side flaps 45 and 46 also jointly form an area which is iw as large as the punched-out area of the second handle opening 9. In contrast, in the embodiment of the packaging material blank 20 shown in FIG. 4, another possibility is provided, which consists in that in the area of the first handle opening 3, the first and second side straps 41 and 42 are each provided with outer curved edges 47 and 48, which lie opposite the respective first and second folding lines 43 and 43 ', while in the area of the second handle opening 9 the first and second side straps 45 and 46 in a corresponding manner each time are provided with outer curved edges 49 and 50, which are then opposite the respective first and second fold lines 43 and 43 '.

Such curved edges 47, 48, 49 and 50 are preferably designed so that they i. w. are each curved inward in the form of a segment of a circle, the described edge configurations of the respective first and second side flaps 41 and 42 or 45 and 46 being produced simultaneously in the punching process in the course of the punching out of the supporting parts in the region of the respective handle openings 3 and 9.

In the embodiment variant shown in FIG. 4, the handle opening results in the respective area 3 or 9 additional punch openings 52 and 52 'on both sides of the punched out support parts. 4 that the respective first and second fold lines 43 and 43 'are each provided with slots 52 and 51' in their central sections.

Starting from a packaging material blank 20 in the embodiment according to FIG. 4, when the resulting packaging body 21 is formed, analogously to the packaging body 21 shown in FIG. 2, the completely free first and second handle openings 3 and 9 are produced in that at the first handle opening 3, the middle tab 40 together with the hanging on this, first and second side tabs 41 and 42 is bent around the third crease line 13, while in the area of the second handle opening 9, the middle tab 44 there together with the first and second side straps 45 and 46 is bent around the fourth folding line 14, which practically represents a first turning process. Because of this first bending process, a first grip edge 13 'is formed in the area of the third fold line 13 and a second grip edge 14' in the area of the fourth fold line 14 '.

As soon as this configuration of the support parts has been reached, further bending processes are initiated in the course of the further assembly of the packaging body 21, which essentially consists in that the first roof surface 5 is bent by the fifth fold line 18 and the second roof surface 7 by the sixth fold line 19, until finally the configuration shown in FIG. 2 is reached.

In this phase of the assembly process, the respective middle tabs 40 and 44 of the supporting parts then also come to an immediate and practically tight mutual superimposition, whereby, for example, the one middle tab 40 comes to rest below the other middle tab 44.

In a subsequent phase of assembly to form the resulting packaging body 21, the respective first and second side flaps 41 and 42 or 45 and 46 are then due to the action of the respective bottles inserted immediately adjacent to the packaging body 21 and in particular due to the action of their Crown cap causes a quasi-automatic snap movement upwards, the respective first and second side straps 41 and 42 or 45 and 46 being at right angles or approximately at right angles or obliquely upwards by kinking around the respective first and second fold lines 43 and 43 'are bent. In the course of the last-mentioned bending process during the final assembly of the resulting packaging body 21, the respective first and second side flaps 41 and 42 or 45 and 46 are now fixed in their respective final assembly position, in which these side flaps are at least partially supported against the inner surfaces of the roof surfaces 5 and 7 arrive, as can be seen for example for the side flaps 41 and 45 from FIG. 5. Here, what is not shown in detail in the drawings for the sake of simplicity, the upper parts or edges of containers, in particular the crown caps of surfaces, are preferably close to the respective first and second side flaps 41 and 42 or 45 and 46. Ultimately, this results in turn a resulting packaging body 21, the handle inner area is designed in such a way that the upper, first and second handle edges 13 'and 14' formed in the respective first and second handle openings 3 and 9 iw by the two, each other corresponding middle tabs 40 and 44, the two corresponding first side tabs 41 and 45 and the two corresponding second side tabs 42 and 46 are connected. In this configuration, the two middle tabs 40 and 44 together form a surface which is parallel to the upper part 6 and has a double material thickness, but at the same time also the respective mutually assigned first side tabs 41 and 45 and correspondingly the respective associated second side tabs 42 and 46 each represent surfaces perpendicular or inclined to the upper part with practically twice the material thickness. This means in practice that a packaging body 21 can now be formed, the resulting inner grip support is characterized by a double material thickness compared to the rest of the packaging, which of course ultimately results in an excellent stabilization of the grip area of the resulting packaging body.

Due to the slots 51 and 51 'provided in the middle sections of the first and second fold lines 43 and 43' according to FIG. 4, the quasi-automatic snap movement of the associated first and second side flaps is achieved during final assembly of the resulting packaging body 21 41 and 42 or 45 and 46 relieved by kinking upwards, particularly obliquely upwards, ie in the direction towards the inner surface of the upper part 6, if these side flaps are acted upon by crown bottles with directly adjacent bottles.

From Fig. 4 it can still be seen that the packaging material blank 20 can be provided on the respective inner sides of the first and second roof surfaces 5 and 7 with reinforcing strips 52, which run on both sides of the upper part 6 parallel to this over a predetermined longitudinal extent and in this case preferably directly adjoin the respective first and second grip edges 13 'and 14'. For the sake of clarity, FIG. 4 shows only a reinforcement strip 52 drawn in dashed lines.

5 shows a detail of an end view of the packaging body 21 formed from the blank 20 according to FIG. 4 in the region of the upper part 6 and the first and second roof surfaces 5 and 7, with FIG. 5 in particular the mutual assignment of first side flaps 41 and 45 can be seen, which are fixed in their respective final assembly position, with a partial mutual overlap and lateral edges of these side flaps 41 and 45 at least partially come to bear against the inner surfaces of the roof surfaces 5 and 7. A corresponding final assembly fixation also results for the respective opposite, second side flaps 42 and 46 if the resulting packaging body 21 is viewed from the opposite end side.

Would you like the arrangement. Fig. 5 look from above in the direction of arrow Pf, it would be seen that in this configuration, the two first fold lines 43 and correspondingly the two second fold lines 43 'cross each other. This is according to the angle α. Fig. 4 conditionally.

In addition, it is advantageous if the length of the respective grip edges 13 'and 14' is approximately equal to the distance a taken in the longitudinal direction between successively arranged punched-outs 17 (see FIGS. 1 and 4).

Due to the inventive design of the inside of the handle is in the resulting packaging body 21 bottles by their crown cap, as already mentioned, a good fixation of the respective first and second side tabs 1, 1 '; 41, 42; 45, 46 reached, so that an additional fixation of these side tabs is no longer required. The internal tension of the cardboard used presses these side flaps over the corresponding crease lines 4, 4 '; 43, 43 'against the respectively adjacent crown cork, which also contributes to an extraordinarily good grip stabilization, so that ultimately tearing in the grip area is practically impossible when the resulting packaging body 21 is worn.

As can also be seen from FIGS. 2 and 3, the packaging material blank 20 also has first and second side surfaces 15 and 16, each of which adjoins the first and second roof surfaces 5 and 7 and the containers to be accommodated in the resulting packaging body 21 , such as B. bottles, cover each side. Here, the transition between the first and second roof surfaces 5 and 7 to the corresponding first and second side surfaces 15 and 16 takes place via corresponding crease lines, the resulting side surfaces 15 and 16 being practically vertically aligned.

From Fig. 3 it can finally be seen that the first and second side surfaces 15 and 16, respectively in each case in inclined surfaces 30 and 30 ', which connecting parts to adjoining floor parts 31 and 31' represent, which in turn are then connected to each other, for example by means of adhesive.

The two inclined surfaces 30 and 30 'are also still provided with cutouts 32 for the bottle bottoms.

Finally, it is also shown in FIG. 3 that a stabilizing web 22 is also provided in each of the front end sections of the upper part 6, which i. w. is bendable vertically with respect to the upper part 6 in the direction of the bottom part 31.

In particular, such an end stabilizing web 22 is laterally connected to triangular connecting webs 23 and 23 ', which represent the connections to the respective front edges 27 and 27' on the first and second roof surfaces 5 and 7.

In detail, the following folding lines are also provided: a seventh folding line 24 between the upper part 6 and the stabilizing web 22, an eighth folding line 25 between the second roof surface 7 and the connecting web 23, a ninth folding line 25 'between the connecting web 23' and the first Roof area 5, a tenth crease line 26 between the stabilizing web 22 and the connecting web 23 and an eleventh Kink line 26 'between the stabilizing web 22 and the connecting web 23'.

It is understood that such a stabilizing web 22 and corresponding triangular connecting webs 23 and 23 'are also provided on the opposite, front end portion of the upper part 6 of the packaging material blank 20.
