Abstract

In a package made from a blank having at least four wide and narrow side walls, connected via folding lines to form a tubular box, with lid and bottom closure tabs articulated thereon, all the wide and narrow side walls being of at least double-layer construction by means of an inside frame, the full inside volume of the package and its rigidity is to be maintained unchanged in a powder-tight design until it is sold, i.e. in all the essential transport and storage operations, without a carrying handle which has to be applied and disposed of separately, but with a gripping depression integrated in the package. This is achieved in that a gripping opening is formed in an outer side wall (16) by folding in a gripping tab (10) along a folding line (12) and an opposite side wall (25) of the inside frame (2) is arranged fixedly in the region above the gripping tab (10) on the tubular box and freely movably in the remaining region (28), the inner side wall (25) being provided at least in the region of the folding line (12) of the gripping tab (10) with a corresponding first folding line (29) and below that approximately at a distance corresponding to the height of the gripping opening with a second folding line (30) to form a gripping depression. <IMAGE>

Description

The invention relates to a package made of a folding blank with at least four wide and narrow side walls connected to a box tube by folding lines with hinged lid and bottom closure flaps, all wide and narrow side walls being formed by an inner frame at least in two layers.

Packaging of this type with a relatively strong inner frame, which essentially brings about the strength of the packaging, has hitherto been used essentially for large 5 kg powder containers and has been provided with a riveted plastic handle at the upper end, which has a number of disadvantages, namely in particular one considerable effort for attaching the handle separately and for disposal by removing the plastic handle. In addition, the handle is annoying when stacking and shrinking shipping units.

An attempt has already been made to remedy this by extending a narrow side wall in a carrying package for receiving powdery or granular products, which is formed from a single-walled cardboard blank, and extending this articulated tab part by multiple grooves to one from the other package interior formed closed recessed grip and formed in the opposite narrow side wall a pivotable grip tab in the recessed grip (DE-GM 86 11 928).

It is disadvantageous, however, that from the start a hollow space is formed in the edge region in the packaging in question, which on the one hand endangers the stability of the packaging during storage and multiple handling, and also brings about a reduction in the fillable internal volume. Larger packagings made from single-walled cardboard blanks also have the general disadvantage that all cardboard parts have to be made of relatively strong and thick corrugated cardboard material in order to be able to absorb the loads that occur in such large containers. This is of course associated with the disadvantage that the formation of the bottom and lid of such packaging is difficult and oversized and, in addition, advertising or content prints on the strong cardboard are practically not possible, so that in addition a wrapping that is actually not necessary for reasons of strength alone is required the application of pressure is required.

It is also known (prior use of packaging according to earlier application P 38 36 069.1) to integrate a carry handle directly into the packaging from a folded blank in a so-called "bag-in-box packaging", one side wall being double-walled and in which outer wall is formed a pronounced grip tab, which forms a handle opening by folding against a corresponding grip tab in the inner wall. When the handle flap is folded in, however, there is a direct opening to the interior of the packaging, so that when a user intervenes by hand, it can damage a foil pouch that holds the contents of the package, especially when finger jewelry is worn. Such packaging is practically unsuitable for the packaging of powdered goods, such as detergent powder or the like, because powder material can escape directly through the opening in the side wall and the user also has to reach into the packaging material when carrying it.

The object of the invention is, on the one hand, a packaging of the type described at the outset without a handle to be attached and disposed of separately, i.e. with integrated recessed grip in powder-sealed design and on the other hand until sale, i.e. to be able to maintain the full internal volume of the packaging and its strength unchanged in all essential transport and storage processes.

In the case of packaging of the type described in the introduction, this object is achieved in that, as is known in the case of the prescribed packaging without an inner frame, a handle opening in an outer side wall by folding in a Handle tab is provided along a fold line and an opposite side wall of the inner frame is fixed to the box tube in the area above the handle tab and is freely movable in the remaining area, the inner side wall being formed at least in the area of the fold line of the handle tab with a corresponding first fold line and to form a recessed grip below is provided with a second fold line at a distance corresponding to the height of the handle opening.

This configuration makes a separate handle completely unnecessary, practically without any additional material expenditure, while maintaining the strength of the packaging and maintaining the entire inner volume until the first use, in which when pivoting the handle flap formed in the outer side wall, the opposite side wall of the inner frame corresponding to the inward pivoting the grip tab is pivoted into the interior of the pack with its opposite pivoting about its first and second folding lines while pulling up its freely movable lower region. It is of particular advantage that the inner side wall in question forms a recessed grip which is sealed off from the inside of the pack by sliding the edges of its movable area along the walls of the inner frame which adjoin at right angles on both sides, so that such packaging is particularly suitable for powdery products Is well usable. The full filling of the packaging is not impaired because powdery material of the type in question is relatively easily compressible, so that the lateral pushing in of the relevant movable area does not cause any problems when forming the recessed grip.

In an advantageous embodiment, the invention provides that for the sealing abutment of the inner side wall on the outer side wall, the inner side wall is provided at the lower end with a lower fold line with the formation of a sealing flap. The design of this sealing flap improves the tightness of the recessed grip, since when flipping and thus moving the movable area of the inner side wall, this flap slides sealingly along the outer side wall.

The tightness is further increased if the inner side wall below the second fold line is provided with a third fold line at approximately the same distance as between the first and the second fold line. As a result, when the handle flap is folded in, a precisely defined, dimensionally stable folding of the inner side wall is achieved; in particular, the sealing flap is guided exactly on the outer side wall when displaced.

The stability of the packaging can be largely maintained even in the formed state of the recessed grip, in spite of the formation of the movable side wall of the inner frame described above, that the lowermost region of the relevant inner side wall is fixed to the box tube.

In order to further improve the powder tightness in the area of the sealing flap, it is expedient to design the side wall of the packaging in this area in three layers. To this end, the invention provides in a further development that a further side wall region is articulated to the inner narrow side wall in a continuation of the supporting frame of the side wall via a folding groove. This further side wall area is folded inwards when the inner box blank is tubed, so that the finished packaging is formed in three layers in this area. In this state, the displaceable sealing flap then lies between the further side wall region and the outer side wall containing the handle opening.

It is particularly expedient here if the length of the further side wall region corresponds approximately to the distance from the folding groove to the middle of the region between the lower fold line and the third fold line.

A three-layer side wall can also be formed if a different embodiment of the cut is selected for the inner side walls. For this purpose, the invention provides that a further narrow side wall is articulated to an inner broad side wall by means of a folding groove, the fixed area of the further narrow side wall reaching up to the height of the grip tab. In this exemplary embodiment, a further, additional narrow side wall is therefore provided, whereas in the previous exemplary embodiment a narrow side wall is of elongated design.

The handling of the packaging is significantly improved in a particularly advantageous development of the invention in that a continuous tear line is formed in a narrow side wall opposite the handle flap and at least in some areas in both broad side walls to form a lid opening in the upper wall area, the two ends of the tear line up to the area of the lid closure tabs run out and each continue in a fold line of the respective lid closure tab. This new type of lid, which is not suitable for known packaging with an additional handle, makes the packaging particularly easy to handle in conjunction with the handle design according to the invention, since the pivoting edge is arranged on the top of the packaging, as a result of which the opening and reclosing is considerably simplified compared to known, lateral pivoting edges. Above all, however, in this embodiment, the user can hold the packaging with one hand and at the same time keep the lid opening open while he can remove good from the packaging with the other hand, or, more advantageously, pour out packaging material over the open narrow side wall by putting one hand on attaches the grip tab and supports the other hand in the area of the diagonally opposite lower narrow edge.

It is particularly advantageous if the two ends of the tear line are designed to run out at an angle to the lid closure tabs, since this results in particularly favorable geometric conditions and thus particularly easy opening.

For the first opening of the lid opening it is provided that the tear line is provided with a tear tape and / or a perforation, as is known per se.

1 to 4, a first embodiment of a packaging according to the invention is shown. This packaging, in particular for powdered goods, such as washing powder or the like, is formed by two folding blanks, an outer folding blank, the folding box blank 1 and an inner folding blank, the so-called inner frame 2. The outer folding blank 1 preferably consists of printed cardboard or the like. and the inner folding blank 2 made of corrugated cardboard.

The folding box blank 1 (FIG. 1) has four box walls connected via fold lines 3, namely broad side walls 4, 5 and narrow side walls 6, 7, to which, via corresponding fold lines, 8 cover closure tabs 4a, 5a, 6a, 7a or bottom closure tabs 4b, 5b, 6b and 7b are pivoted.

On the free longitudinal edge of the broad side wall 4, an adhesive flap 9 is also foldably arranged for gluing to the narrow side wall 7. This adhesive tab 9 likewise has a lid closure tab 9a and a bottom closure tab 9b, which may also be omitted.

In the narrow side wall 6, a grip tab 10 is formed in the upper area, which is delimited by a perforated punching line 11 and a folding line 12. By pressing in correspondingly along the punching line 11, the Handle tab 10 can be folded inwards along the folding line 12 with the folded-up folding box blank 1 erected and tubed.

To form a lid opening, a continuous tear line 13 is formed in the narrow side wall 7 and the adhesive flap 9 in the upper wall area, which continues in some areas in the two wide side walls 4 and 5 and whose ends 14 run obliquely to the lid closure flaps 4a, 5a and in each case in fold lines 15, 16 pass into the lid locking tabs 4a and 5a. The obliquely tapering ends 14 are perforated, while the remaining area of the tear line 13 is provided with a tear tape, which is only indicated in the drawing and is designated by 17.

Fig. 2 shows the cutting of an inner frame. This has side walls connected to one another via dashed fold lines, namely broad side walls 18, 19 and narrow side walls 20, 21 and an adhesive flap 22, this adhesive flap also being dispensed with.

In the folded and tubed state, the inner frame is inserted into the folding box blank 1 in such a way that the inner narrow side wall 20 abuts the outer narrow side wall 6. The training is essential for the design of the inner folding blank 2 the inner narrow side wall 20. This side wall is formed in two parts. It consists of a support frame 23 adjoining the bottom surface of the hose and folded folding box, which is connected in a fixed manner to the adjacent broad side walls 18, 19 via fold lines 24, and an inner side wall 25 separate therefrom. This inner side wall 25 in turn has two areas, one Upper region 26, which is connected in a fixed manner to the broad side walls 18, 19 via inner fold lines 27 and whose width corresponds approximately to the distance between the fold line 12 of the grip tab 10 and the fold line 8 of the outer fold blank 1, and a second region 28, which via a the first fold line 29 is pivotably articulated on the area 26 and the remaining edges 28a thereof, shown in the drawing as solid lines, are not connected to the adjacent areas of the inner frame 2. The edges 28a are formed by punching or cutting through the inner frame 2. A second fold line 30 and approximately the same distance therefrom a third fold line 31 are formed approximately at the distance corresponding to the grip tab 10 of the outer folding box blank. At the lower end of this movable area 28, a lower fold line 33 is provided to form a sealing tab 32. The areas of the inner frame 2 and the hose-folded and folded-up folding box blank, which are adjacent to one another in the area of the support frame 23 and the upper area 26, can be glued together.

Fig. 3 shows a side view of a complete package formed from the two folding blanks 1 and 2. In this case, the handle opening, generally designated 34, has already been formed, although only the shape of the movable region 28 of the inner narrow side wall 20 is indicated by dashed lines; further details are described below. By tearing open the tear tape 17 along the tear line 13 and correspondingly tearing along the perforated ends 14, a lid of the packaging designated 35 can be opened, the arrangement of which is such that the tear line 13 is not formed in the narrow side wall 6 with the grip tab 10 . This arrangement is particularly favorable for removing or pouring goods out of the packaging and enables easy handling.

Fig. 4 illustrates the configuration of the handle opening 34. By folding the handle tab 10 after the perforated punching line 11 has been cut accordingly, the movable region 28 of the inner side wall 25 is correspondingly displaced such that a recessed grip is formed. This displacement takes place in a defined manner due to the folding lines 30 and 31, the sealing flap 32 in particular being displaced sealingly along the outer narrow side wall 6 due to the folding line 33, so that no powdery material 36 is in the area of the Grip recess can reach, ie no good can escape through the handle opening 34.

When the recessed grip 34 is open, the powder tightness is further improved by the inner frame cut 2a, as shown in FIG. 5. The inner frame cut 2a according to FIG. 5 essentially corresponds to the inner frame cut 2 according to FIG. 2 and is therefore provided with the same reference numerals for the same parts. Different from the inner frame cut 2a is the elongated narrow side wall 20. Here, a further side wall region 61 is articulated to the supporting frame 23 by means of a folding groove 60. This side wall region 61 has approximately a length which corresponds to the distance from the crease line 60 to half of the side wall region 28, and is folded inwards when the inner frame blank 2a is connected and connected to the support frame 23. In this way, the inner frame is then double-layered in the region of the side wall region 61, as can also be seen in FIG. 6. In this way, when the carton with the inner frame is filled with product, the product only lies in the area 61, whereas between the other side of the area 61 and the inside of the outer narrow side wall 6 there is a space in which the movable area 28 of the side wall 25 is slidably arranged . While in the formation of the inner frame 2 in the state according to FIG. 4 there is possibly still the risk that when If the recessed grip 34 still opens between the sealing flaps 32 and the outer narrow side wall 6, which can then emerge from the folding box undesirably through the handle opening 34, this is not possible when the inner frame 2a is formed, as can be seen in FIG. 6.

7 and 8 also show the design and arrangement of an inner frame blank 2b, which likewise brings about an improved powder tightness compared to the inner frame blank 2. 7 and 8 too, the parts identical to FIGS. 2 and 4 are provided with the same reference numerals. The inner frame 2b is distinguished by a different sequence of narrow side walls 20, 21 and broad side walls 18, 19 and an additional narrow side wall 70. The narrow side wall 20 according to FIG. 7 is designed in exactly the same way as the narrow side wall 20 of FIG. 2, but because of its outside arrangement in the blank 2b it is only connected to the wide side wall 19 via the fold or crease lines 27 and 24. The narrow side wall 70 formed on the other side of the blank 2 b is articulated on the wide side wall 18 by a fold line or scoring 71. The folding scoring 71 extends approximately from the lower edge of the inner frame blank 2b to a height which corresponds approximately to the lower profile of the perforation line 11 bordering the handle tab 10 in the folding box blank 1. From there to to the upper edge of the inner frame blank 2b, the folding line 71 continues as a punching or cutting line 72. In the transition area from folding line 71 to punching line 72, another folding line 75 begins, which runs perpendicular to lines 71 and 72 and divides the narrow side wall 70 into the lower area 73 and the upper area 74.

When the container is ready for use, the inner frame 2b is folded in such a way that the narrow side walls 70 and 20 come to lie against one another, as can be seen from FIG. 8. The wall 70 then forms the inner position of the inner frame facing the product and the wall 20 forms the position of the inner frame 2b facing the narrow side wall 6. Also in this embodiment, the inner frame is then formed in the region of the narrow side wall 6 in two layers, similar to the embodiment according to FIGS. 5 and 6. If the handle tab 10 is now pressed inwards in this container, the upper region 74 of the narrow side wall 70 folds down away from the inside and allows the handle tab 10 to be folded over and the part 25 of the wall 20 to slide up. This embodiment also prevents powder 36 from passing past the sealing tab 32 to the opening 34. The parts 73 and 23 can be glued together.

In a modification of the inner frame blank 2b according to FIG. 7, the fold line 75 can also be designed as a punched line, so that the upper region 74 is then completely eliminated. Although this embodiment is not shown any further, it can immediately be seen that similar relationships result in the sectional view as are shown in FIG. 6. The difference to FIG. 6 is then that the double wall of the inner frame in the region of the narrow side wall 6 is not formed by a part 61, which is formed on the narrow side wall 20, but by the part 73, which is formed on the narrow side wall 70 .
