FOLDING BOX, CUTTING AND MANUFACTURING METHOD OF

CARTON

The invention relates to a carton with a tamper-evident closure.

There are a variety of cartons with a tamper-evident closure known, however, all have the disadvantage, on the one hand to be very expensive to manufacture and on the other hand, if at all, be poorly resealable.

The object of the invention is therefore to propose a carton, on the one hand has a tamper-evident closure, good and often resealable, and is also inexpensive to manufacture.

This object is erfmdungs according solved in that a first front wall is provided with a first detent strip hinged thereto, a bottom wall, a rear wall and a top wall, wherein on the top wall, a second front wall is arranged with a second locking strip.

The two locking strips are able to support one another and thus form a reclosure. It is also very advantageous according to the invention if the end faces of the packaging are closed by side wall sections and / or closure flaps.

As a result, a well-filled, but nevertheless sufficiently dense and stable packaging is created.

Another very advantageous embodiment of the invention is when at least one side wall tabs is disposed on the top wall, which may be connected to the second front wall in each case.

This creates a stable cover from the top and front wall. It is also ensured that the front wall occupies a fixed angle to the top wall.

It is extremely advantageous according to the invention if the first front wall is provided with one or more splices to which the second front wall is glued, sealed or otherwise connected.

Hereby, the second front wall is securely connected to the first front wall.

It is also very advantageous according to the invention, if on the front wall

lapped hinge closure are provided with one or more splices on which the second front wall or a side flap of the second front wall is glued, sealed or otherwise connected.

This also creates a connection between closure flaps and side flaps in the region of the front walls. Closing the packaging after filling is facilitated because the flap does not have to be glued separately. Furthermore, it is inventively very advantageous if the hinged on the rear wall closure lapping are provided with one or more splices to which a side flap of the top wall is glued, sealed or otherwise connected.

Thus, a second closure is formed, which must be broken when first opening the package.

It has proven to be very advantageous if the splices are each surrounded by a line of weakness, which may be arranged in the first or the second front wall, the side flap and / or the closure flap.

This allows the splice to be separated. At the same time it is ensured that a preceding opening of the packaging is recognizable. A tamper-evident closure is thus given.

It is extremely advantageous in this context if the weakening line is designed as a scribe line, which may be continuous or interrupted, or the like.

Likewise, it has proved to be very advantageous if the splice and / or the wall material is formed delaminating in the region of the splice.

This ensures a defined openability.

According to a development of the invention, it is extremely advantageous if a part of the fold lines is formed at least in sections as double fold lines or wider fold lines or at least partially replaced by scoring or cut lines. It is very advantageous if the double fold lines, wider fold lines, scoring or cutting lines are arranged in the first front wall in the region of the overlap by the second front wall.

These double fold lines, wider fold lines, scoring or cutting lines can be used to adapt adjoining walls during folding. Thus, this special Faltlinienausgestaltung a double-layered wall with hinged flaps are folded clean and accurate.

Another very advantageous embodiment of the invention is when the two locking strips are able to get caught against each other.

This ensures a secure hold.

A particularly advantageous embodiment for a blank for a

Folding box according to the invention is present when a bottom wall is hinged to a first front wall via a fold line, on which in turn via fold lines a

Rear wall and a top wall follows.

This can be easily folded a tubular packaging.

It is very advantageous if at the free, the rear wall opposite edge of the top wall by means of a fold line, a second front wall is hinged.

This second front wall may overlap the first front wall.

According to the invention, it is also very advantageous if in each case a latching strip is articulated on the free edges of the first and second front wall.

With the help of this locking strip a reclosure of the erected packaging can be made possible. Another very advantageous embodiment of the invention is when in

Overlap region of the two front walls one or more splices are provided, which are surrounded by a line of weakness and / or as

Delaminierender area are formed.

It is also very advantageous according to an embodiment of the invention, when in the overlapping region of the hinged on the front wall closure flap and the second front wall or a side flap of the second front wall one or more splices are provided, which are surrounded by a line of weakness and / or formed as delaminierender area ,

Furthermore, it is very advantageous according to the invention if one or more splices are provided in the overlap region of the closure flaps hinged to the rear wall and the side flaps of the top wall, which are surrounded by a weakening line and / or are designed as a delaminating region.

All these possibilities are used individually or in combination

Originality closure created, which is easy to open despite ensuring the originality and also keeps the packaging securely closed during transport.

A very advantageous development of the invention is also present when a part of the fold lines at least partially formed as a double fold lines or wider fold lines or at least partially replaced by scoring or cutting lines, the double fold lines, wider fold lines, scoring or cutting lines in the first front wall in Area of overlap can be arranged through the second front wall.

These double fold lines, wider fold lines, scoring or cutting lines can be used to adapt adjoining walls during folding. So can through this particular Faltlinienausgestaltung also a two-ply wall with hinged flaps clean and accurately folded. The inner layer when folded over can be shortened by this fold line configuration by the fold line area is compressed.

It is also very advantageous if on the side edges of the sections

Side wall tabs or dust flaps are hinged.

Thus, the packaging can be closed after filling.

A particularly advantageous method for producing a packaging according to the invention with a blank according to the invention is when initially the following on the second front wall locking strip is folded back and can be fixed there.

This will be an essential step in the formation of the packaging from the

Cut done.

It is very advantageous if the fixation is done by means of a previously applied adhesive trace.

Thus, the locking strip is securely fixed.

Furthermore, it is very advantageous if the following on the first front wall

Detent strip is folded forward.

As a result, the second part of the latching reclosure is created.

An inventively very advantageous method is when the blank is folded at the fold line between the bottom wall and rear wall, and then the second front wall is folded onto the first front wall and fixed there in the gluing area. The bonding takes place in the edge area.

It is also very advantageous according to the invention, when the blank is folded at the fold line between the first front wall and bottom wall and between the rear wall and top wall, and then placed the second front wall on the first front wall and fixed there in the gluing area.

This standard machines can be used. The bonding takes place in the middle.

A very advantageous development of the invention is also present when the side tabs are glued to the closure flap and so the splice is formed.

As a result, an additional bonding of the side lobes when closing the package is avoided. Rather, this area is already pre-glued.

It has also proved to be very advantageous according to the invention when the pre-glued packaging is erected into a tube, filled laterally and then the

Side panel flaps are glued or sealed together and so the

Packaging is closed.

This creates a filled and sealed packaging in a simple manner.

In the following the invention is illustrated by means of an embodiment. Showing:

can be erected Fig. 2 shows another blank from which a package according to the invention can be erected, in perspective view

3 shows the preceding blank in which the first locking strip is folded and glued,

4 shows the preceding blank, in which the second front wall is placed on the first front wall,

5 is an erected, but not yet sealed packaging,

6 is a partially sealed packaging,

7 shows a sealed packaging,

8 a reopened packaging,

Fig. 9 shows a blank with additional, the side lobes of the second

Front panel gluing, as well as a double fold line, and

Fig. 10 shows a modification of the above blank with a cutting line instead of the double fold line.

1 denotes a blank for a folding box in FIG. 1. At a first front wall 2, a bottom wall 4 is articulated via a folding line 3, to which in turn a rear wall 6 connects via a folding line 5. On the rear wall 6 is followed by a fold line 7, a top wall 8, in turn, via a fold line 9, a second front wall 10 connects. The second front wall 10 takes in this embodiment only a part of the height of the carton; but it is quite possible that this can take the full height.

In the region of the overlap of the front wall 2 and the second front wall 10, a splice 1 1 is provided which is surrounded by a score line 12, which weakens the surface of the first front wall 2 so that when opening the finished packaging, the splice 1 1 from the first Front wall 2 is torn out without an opening is formed.

On the free side of the first front wall 2, a first latching strip 13 is provided, which is folded over the folding line 14 in the finished packaging to the outside.

On the free side of the second front wall 10, a second locking strip 15 is arranged, which is folded when erecting the packaging on the fold line 16 inwards and is fixed there with an adhesive strip 17 provided on the locking strip 15.

It is conceivable that the adhesive trace 17 is also arranged on the second front wall 10.

At the front side edges of the blank 1 18 side wall portions 19 are hinged to the bottom surface 4 via lateral fold lines, which are folded after filling the package by 90 ° and thus form the side walls of the package. In addition, on the first front wall 2 hinged via fold lines 20 front side wall tabs 21 and on the rear wall 6 via fold lines 22 hinged rear side wall tabs 23 are provided, which are folded onto the side wall portions 19 and fixed there.

The fixation can be done for example by gluing. On the top wall 8 upper Seitenwandabschmtte 24 are arranged on fold lines 25. These are with side wall tabs 26, the folding lines 27 with the second

Front wall 10 are connected, glued.

By the side wall portions 24 and the side wall tabs 26 a slip lid is formed, which can be pivoted about the fold line 7 around.

When you first open the packaging, the splice 1 1 is released from the front wall 2. Thereafter, when re-closing the locking strips 13 and 15 in succession and allow a safe, but still easily revealed

Reclosure.

If the carton is formed from the blank 1, then the locking strip 15 is first provided with an adhesive trace 17 and folded inwards.

Subsequently, the package along the fold line 5 between the bottom wall 4 and rear wall 6 is folded, so that the two locking strips 13 and 15 come to lie directly next to each other.

After the adhesive surface 11 is also provided with adhesive, the second front wall 10 can be folded over, so that it comes into contact with the adhesive surface 1 1 and is fixed.

In this case, the locking strip 13 is also folded over and thus brought into the intended position.

For this process, it is necessary that the adhesion takes place at the edge of the blank. This can not necessarily be realized with all conventional packaging machines. Often these are designed for bonding in the middle area. However, a second variant is possible. Here, again, the locking strip 15 is first provided with a glue trace 17 and folded inwards.

Subsequently, the package along the fold line 3 between the first front wall 2 and bottom wall 4, and along the fold line 7 between the rear wall 6 and

Cover 8 folded. In addition, the locking strip 13 is folded along the fold line 14 to the front.

After the adhesive surface 11 is also provided with adhesive, the second front wall 10 is brought into contact with the adhesive surface 1 1 and fixed.

When erecting the packaging, a tube is formed, in which the filling material can be inserted. Subsequently, the side wall portions 19 are bonded to the side wall tabs 21 and 23 and so closed the package.

Finally, the upper side wall portions 24 are glued to the side wall tabs 26 and formed as the slip lid.

The packaging is suitable for a variety of products. Especially conceivable are hygiene applications. This includes the packaging of panty liners, for example. These are removed piece by piece, so that a reclosability of the package, as proposed according to the invention, is advantageous.

The adhesive surface 1 1 may have a variety of shapes. Depending on the purpose, this can be round, oval, rectangular, rectangular rounded or heart-shaped. Other regular and irregular shapes are conceivable. These include triangular and polygonal shapes. In addition, it is conceivable that a plurality of adhesive surfaces 11 are provided.

According to the variant of the invention shown in FIG. 9, a first front wall 902 is provided which has the already described splices 11. In the on it hinged side wall tabs 921 further splices 91 1 are provided, which are glued to the side wall tabs 926 of the second front wall 910.

The splices 91 1 are surrounded by weakening lines 912. Due to the

Arrangement in the edge region of the side wall flap 921, the splice is only partially surrounded by the line of weakness 912. The rest forms the edge of the sidewall lobe.

When opening the package, the splice 91 1 is torn out of the side wall tabs 921. Previously, this is a tamper-evident closure formed.

The side wall tabs 926 can be glued during prefabrication with the splice 91 1. When erected into a sleeve, the side wall flaps 921 and 926 are then already connected together, as are the front walls 902 and 910.

To those resulting in bending the side wall tabs 921 and 926 resulting

To compensate for longitudinal displacement, the fold lines 20 are replaced by a double folding line 980 in the region of the overlap height of the two front walls 902 and 910. The double folding line 980 consists of two predetermined folding lines, which may be formed for example by embossing or creases, which are arranged side by side at a small distance from each other.

The distance corresponds approximately to the expected length compensation.

The two creases can move against each other, as they represent a weakening of the cardboard material.

Alternatively or in combination, instead of the double folding line 980, a correspondingly wide folding line may be provided, the width of which corresponds to the spacing of the two fold lines of the double fold line. It is equally possible, instead of the

Double fold line 980 to provide a scoring or cutting line 981, as shown in Fig. 10 is shown. The combination of fold lines and scoring or cutting lines is also conceivable within a line. Scoring lines partially penetrate the cardboard material, whereas cutting lines at least partially cut the cardboard material

penetrate.

Another variant is likewise shown in FIGS. 9 and 10. The side tabs 923 hinged to the rear wall 906 may be connected to the side tabs 924 with a splice 91 1a, which in turn may be separable from the side wall tab 924 by a line of weakness 912. The side wall tabs 924 are hinged to the top wall 908.

This splice 91 la may be provided near the rear wall 906 as shown.

This embodiment again represents an origami closure and reinforces and secures the packaging during transport.

With appropriate dimensioning of the side wall tabs, it is also possible to provide a tight package, which is suitable for example for receiving free-flowing fillings.

By means of gusset corners, the transitions can be sealed.
