Abstract

The dispenser box has four peripheral walls (4, 6, 8, 10), a bottom and a lid, it being possible for a removal flap (24) with two lateral boundary tabs (28, 30) of the opening to be swivelled out of the front peripheral wall (4). The boundary tabs (28, 30) of the opening are constructed integrally with a material strip (38) which is bonded to the inside of the removal flap (24). Said material strip is preferably made integrally with the bottom tab (72), which is attached to the front peripheral wall (4), of the bottom, which is constructed as a foldable bonded bottom, and is connected to said bottom tab via a tear-off edge (78). The material strip (38) is then folded, together with the bottom tab (72), in an automatic folding stage onto the inside of the blank and bonded in its position. When the dispenser box is set up from the flat-folded state into the box shape, the bottom tab (72) lifts up from the peripheral wall (4), thus tearing off the tear-off edge (78). <IMAGE>

Description

The invention relates to a folding box in the preamble of claim 1 and a method for their production.

With such folding boxes, the front wall always borders, a side wall, the rear wall and another side wall in the sequence shown together; accordingly be is the not yet processed box cut from four in this episode connected to each other via folded edges partitions, this sequence with any of the ge called four peripheral walls can begin. On the free longitudinal edge of one of the two outer peripheral walls is generally mean an overlap adhesive tab arranged. For education the folding box is then, for example, the one with the overlapping adhesive flap provided peripheral wall and there after the other outer peripheral wall flat on the box cut folded, the outer edge of the latter with the previously glued overlap glue tab is glued. From this flat folded state, the carton can are unfolded in a known manner, being from the flat form suitable for shipping over a form with diamond-shaped plan in the final form with good reason square floor plan.

At the top and bottom edges of the peripheral walls are Bo and the cover flaps arranged over folded edges. For the The floor is between a plug-in shelf and a folding adhesive board the differences. The peg is generally after unfolding the carton by nesting the Bottom flaps formed, this process hardly being automatic is sizable. To form the folding adhesive base, the Bo denlaschen in particular, based on an embodiment  folded in more detail and glued so that a folded one, in the plane of the flat fold box-lying bottom results, which when unfolded the folding box is stretched. The formation of the Folding adhesive floor is generally carried out simultaneously with the Formation of the folding box and is easy to automate.

The removal flap arranged on the front peripheral wall can be opened like a dump flap, the two opening limitation tabs on the one hand the side walls form this dump flap, on the other hand for guiding and Opening restriction of this pouring flap are formed, as will be explained in more detail.

To the buyer of the flat-folded folding boxes To facilitate use as much as possible, one is strives to be in a largely completed state offer, so that the customer himself as little hand as possible grips to the creation of the ready-to-use box must afford. Another goal is given the box size the ready-to-ship, flat folded fold Box format as small as possible and thus the packaging to keep the wall as low as possible.

It is already a folding box in the top handle of the An known type 1 known, in which the removal flap integrally formed with the opening limiting tabs and is connected to a bottom flap (EFKA folding box PRINT, version 1). With this folding box, the Removal flap which is essentially the same in size and shape Ent to be closed opening in the front peripheral wall speaks, not be punched out of this, since the one with the Removal flap connected opening limit tabs then necessarily out of the lateral peripheral walls would have to be cut. For the entire, out of flap and attached opening limiting flaps existing bulk  flap must therefore have a separate cutting area will see; accordingly must be on the front circumference wall a dump opening can be cut out. Overall he this gives a relatively large, unfavorable ge structured cutting or utility format.

The pouring flap is on in the known folding box a bottom tab connected to the rear peripheral wall arranged. The bottom of the well-known folding box is as Plug-in base trained. Because the plug-in floor is only at the customer can be formed after unfolding the folding box also the filler flap from the user in a cumbersome manner be brought into their use form and position. This This process is just as impossible as plugging the floor automate. The well-known folding box has therefore in ready for dispatch an extremely low manufacturing degree and an undesirably large crop format.

It is the object of the present invention to make a fold Box of the type mentioned in the preamble of claim 1 to create which is possible with a given box size very small and closed, with little waste producible cut format and which in ver sand-ready condition as far as possible, a ver application for the customer to facilitate the degree of production sits; another task is to create a simple, rational manufacturing process for the production of a Specify folding box according to the invention.

According to the invention, the first subtask is characterized by Character of claim 1 specified features solved.

The removal flap is immediately out of the front circumference wall punched out so that the removal flap and the Ent opening in one operation with one tool be put. In addition, the removal flap is inside  half of the outline of the front peripheral wall, so that no ge special annex, which enlarges the utility format, is provided have to be. By sticking the material strip with the there ran, for example, over opening edges attached to folded edges the discharge flap is completed. they is after sticking the material strip from even in the intended position of use, so that inso far a very extensive degree of production is achieved and the completion items still to be provided by the user are low.

When folding the box blank to the flat Folding box in the manner described above and Wise at least one of the two opening limit lash together with a lateral peripheral wall by 180 ° folded flat on the front peripheral wall. When unfolding the box must put this opening restriction tab together with the lateral peripheral wall against which it lies, by 90 ° be erected. To prevent this opening limiting tab in an only partially erected Position remains and in the interior of the unfolded In one embodiment, the box protrudes into the Er provision provided that that with the removal flap closed inner end of this opening limitation tab against a lifting ge from this peripheral wall by a fuse is secured; this fuse is designed so that it automatically when the removal flap is opened for the first time can solve. With this fuse, when unfolding the Folding box the opening limit flap from the ordered circumferential wall taken.

In a preferred embodiment of the invention, that the secured opening restriction tab by engagement between the associated adjacent peripheral wall and one this glued overlap adhesive tab on the back Peripheral wall is held. The gluing area between  Overlap adhesive flap and peripheral wall can be in the area of Intervention of the opening limitation tab be interrupted, so that it is only held positively. When opening the removal flap becomes the inner end of the opening out the border flap under the overlap glue flap pulled, which releases the fuse.

In order to be able to produce the box blank in one piece, the material strip is preferably in one piece with it Cut connected and hangs with this over a tear edge together. He can then be separated if necessary and in the front seen position are transferred. In a preferred version staltung of the invention, the box blank is in one piece with a bottom flap of the front wall and hangs with this together over a tear edge. The arrangement can be so be taken that after folding the bottom flap around its folded edge on the inside of the front peripheral wall the material strip automatically in its exact target position arrives in which it should be glued. In this way is an exact positioning with simple, well known Folding facilities possible, so that this process without Difficulties can be automated.

In a preferred embodiment of the invention is pre see that with training the floor as a folding adhesive floor in articulated and glued bottom tabs the circumferential walls, which when the jacket unfolds to Stretch the floor, the strip of material connected to the Bottom flap of the front peripheral wall is made and of by opening the jacket for the first time can be torn off automatically. The strip of material becomes together men with the bottom flap of the front peripheral wall, which for Folded anyway for the purpose of forming a foldable adhesive base must be brought into their target position and glued. It remains connected to this bottom flap as long as the  Folding box maintains its flat folded state. The The tear edge is designed so that when folding the fold box, i.e. then when the bottom flap out of their for front peripheral wall parallel position in the floor level is pivoted, the strip of material from this floor tab is separated.

The present invention also relates to a method the kind mentioned in the preamble of claim 7. As there emerges, after provision of a suitable, all or all of the essential parts of the folding box pointing cut individual tabs glued and the Zu cut into the flat folded, ready-to-ship form, the glued tabs with the corresponding counter glue surfaces. In the known folding box, the Removal flap with those attached to it over folded edges Opening limitation tabs as separate, on a floor cut out the attached cut part. From this Order results that the removal flap only when open usually fold the folding box manually in several Process steps are brought into their position of use, so that a substantial part of all up to the deployment of the finished, usable folding box required Operations very inefficient and also by the user leads. In addition, the known Ver drive an unfavorable, a relatively high Ver Benefit form dependent on the cut share, as already stated has been.

It is another object of the present invention to provide a ver drive to manufacture a folding box to indicate at which is the degree of manufacture of the flat folded fold box is as high as possible and with a cheap, low-waste benefit form is achieved.  

This object is achieved by the in the license plate of claim 7 contained features solved.

The actual removal flap is in one with the Zu cutting the benefits coincident or a separate Operation out of the surface of the front peripheral wall punches in such a way that it folds in with this over a folded edge Connection stays. There is no opening to remove the limiting tabs in one piece with the removal flap form; instead, in a separate process step on the inside of the removal flap strips with side opening tabs glued. Based on the method according to the invention a folding box, in the flat folded state the folding box the removal flap is already in use position. When unfolding the carton the opening limitation tabs together with the assigned lateral peripheral walls automatically in their position of use, so that no separate, concerning the removal flap Operations are required.

If the bottom of the folding box is a so-called folding adhesive is formed bottom, which when folding the fold box stretches, is the Er in a further embodiment provision provided that the strip of material from an Ab tear edge with the bottom flap of the front peripheral wall is made coherent that the strip of material be is glued and that it is simultaneously with the bottom flap of the front peripheral wall folded on this and with the Ent the flap is glued. As already stated, this manufacturing process leads to a folding box that only be unfolded from the flat folded state must, the strip of material automatically from the floor tab tears off, so that they stretch into the floor level can. A folding box made by this process can therefore be easily folded up mechanically,  except for possibly closing the lid Operations are required which require a manual on make grip necessary.

Several embodiments of the invention are in the Drawing shown and described in more detail below. Show it:

Figure 1 is a perspective view of a folding chute tel in the unfolded state with the flap open Ent.

FIG. 2 shows a box blank for producing a folding box according to FIG. 1 with a view of the inside of the wall;

. Fig. 3 shows the carton blank of Figure 2 after working sizing of the parts to be bonded and after a first folding operation;

Fig. 4 is a folding box of Figure 1 during the folding on in a view obliquely from below.

Fig. 5 is a view of the open-top folding box of FIG. 1 in the direction of arrow IV, the individual peripheral walls are pulled apart with the attached bottom flaps.

The folding box 2 shown in FIG. 1 has a casing which is formed from the front peripheral wall 4 , the lateral peripheral wall 6 , the rear peripheral wall 8 and the further lateral peripheral wall 10 . A bottom 12 closes the lower end face, a cover 14 the upper end face of the folding box 2 . The bottom 12 can be formed in a known manner as a plug-in base or as a folding adhesive base; the cover 14 is generally a plug-in cover with inner cover flaps 16 and an outer cover flap 18 provided with a plug-in flap 20 .

In the front peripheral wall 4 , a removal opening 22 is formed, which can be closed by a removal flap 24 of the same shape and dimension. The removal flap 24 is pivotable about a folding edge 26 close to the floor between the open position shown and one in the plane of the position lying in front of its peripheral wall 4 .

On the side edges of the removal flap 24 opening brackets 28 , 30 are arranged, which abut on the inner sides of the associated lateral peripheral walls 6 and 10, respectively. The opening limitation tabs 28 , 30 together with the removal flap 24 form a pouring flap 32 and form the side walls thereof.

At the inner ends of the opening limiting tabs 28 , 30 stop lugs 34 , 36 are formed which, in the open position of the pouring flap 32 shown in FIG. 1, bear against the front peripheral wall 4 on the inside and thus limit the opening path of the pouring flap 32 .

The opening limiting lugs 28, 30 are formed integrally with a glued to the inside of the removal flap 24 material strip 38 and the latter via folding edges 80, connected 82 grenzungslaschen a folding the Öffnungsbe 28, 30 to 90 ° allow out of the plane of the material strip 38 .

The material strip 38 with the attached opening limit tabs 28 , 30 can for example be produced as a separate part and glued to the flat blank blank. However, a carton and a method of manufacturing the same will be described with reference to FIGS. 2 to 5, which make it possible to manufacture the strip of material 38 and the accompanying opening limiting lugs 28, 30 in one piece blank in a particularly simple manner with the folding box and further process.

The folding box blank or use 44 shown in FIG. 2 is used to produce a folding box according to FIG. 1. All parts corresponding in the two figures are therefore provided with the same reference numerals. The lateral circumferential wall 6 , the front circumferential wall 4 , the lateral circumferential wall 10 and the rear circumferential wall 8 are hinged together by common, formed as folded edges longitudinal edges 46 , 48 , 50 . The inner cover tabs 16 are connected to the lateral circumferential walls 6 and 10 via folded edges 52 . The outer cover flap 18 is connected to the front circumferential wall 4 via a folded edge 54 and in turn carries the plug-in flap 20 via a folded edge 56 .

On the free side edge of the rear peripheral wall 8 , an overlap adhesive flap 60 is arranged in an articulated manner via a folded edge 58 .

At the lower edges of the side circumferential wall 6 , the front circumferential wall 4 , the lateral circumferential wall 10 and the rear circumferential wall 8 , bottom flaps 70 , 72 , 74 and 76 are arranged over the articulated folding edges 62 , 64 , 66 and 68, respectively. The bottom flaps 70 , 72 , 74 , 76 are designed in such a way that they can form a folding adhesive base, as will be described in more detail below.

With the bottom flap 72 is connected to a tear-off edge 78 of the material strip 38 , on which over the articulated folding edges 80 and 82 hang the opening limitation tabs 28 and 30 , respectively.

FIG. 3 shows the blank 44 according to FIG. 2 after it has passed through a gluing station and a first folding station. The areas to be glued to each other are shown hatched, whereby it can remain open which area of each pair of areas receives the glue application and what the glue application looks like, for example, punctiform, strip-like or the like Surface is glued to the counter surface; The continuous hatching means accordingly that the upper side of the corresponding surface with respect to the drawing plane represents an adhesive surface. In Fig. 3 it can be seen that the underside of the overlap adhesive flap 60 and the left edge area 61 of the lateral peripheral wall 6 form an adhesive surface pairing. Further pairs of adhesive surfaces each form parts of the bottom flaps 70 and 72 or 74 and 76 , as will be described in more detail below. As can be seen in particular in FIG. 2, the bottom flap 70 consists of a main part and a flap 70 a attached to it via a folded edge 71 . The bottom flaps 76 comprises a main part and a thereto attached via a fold edge 77 tabs 76 a.

As can be seen from Fig. 3, the bottom flaps 70 , 72 , 74 and 76 are folded in one operation around the respective folding edges 62 , 64 , 66 and 68 and placed flat on the peripheral walls 6 , 4 , 10 and 8 respectively. At the same time, the flap 70 a connected to the bottom flap 70 is folded back around the folded edge 71 , so that the side of the flap 70 a which is at the top in FIG. 2 is also at the top in the arrangement according to FIG. 3. Similarly, the coherent with the bottom flap 76 flap 76 a Retired to the fold edge 77 is folded so that the constellation of the bottom flaps illustrated in FIG. 3 results in 70 and 76 with the attached tabs 70 a and 76 a.

The material strip 38 is folded together with the bottom flap 72 so that it flaps 24 on the inside of the removal. The opening limiting tabs 28 and 30 lie on the associated lateral circumferential walls 6 and 10, respectively. The folded edges 80 and 82 are flush with the folded edges 46 and 48 . Before folding the bottom flaps 70 , 72 , 74 , 76 , for example, the side of the material strip 38 lying on top in FIG. 2 has been glued. If the material strip 38 hangs in FIG. 3 on the inside of the removal flap 24, it will be glued to it (it is understood that the congruent with the strip of material 38 face of the removal flap 24 can be glued).

Before further folding of the blank 44 taking the state according to FIG. 3, at least one of the two assigned hatched areas of the flap 70 a or the bottom flap 72 on the one hand and the flap 76 a or the bottom flap 74 on the other hand is glued. In a next process step, the rear peripheral wall 8 is folded around the folded edge 50 so that it lies on the lateral peripheral wall 10 and on part of the front peripheral wall 4 . Then the lateral peripheral wall 6 is folded around the folded edge 46 so that it also lies on the front peripheral wall 4 , the adhesive region 61 being placed on the overlap adhesive flap 60 and being glued to it. At the same time, the mutually assigned hatched areas of the flap 70 a and the bottom flap 72 on the one hand and the flap 76 a and the bottom flap 74 on the other hand are glued together. The state of the blank 44 thus achieved corresponds to the flat folded, ready-to-ship folding box.

As is 3 resulting from a consideration of Fig., When folding the lateral peripheral wall 6 also Öffnungsbe grenzungslasche 28 is entrained and flat on the strip of material 38 placed. Since the out as a stop lug 34 formed end of the opening limiting tab 28 protruding portion 61 in the adhesive, there is between this adhesive portion 61 and pinched the overlap glue flap 60th So that the stop lug 34 is not glued to the peripheral wall 6 or the overlap adhesive tab 60 , the gluing is interrupted in the area in which the stop lug is pinched, as shown in FIG. 3.

FIG. 4 shows a folding box according to FIG. 1 during the unfolding from its flat folded state into the box shape. If the folding box 2 is loaded, for example, by a folding device in the direction of the arrows P 1 and P 2 , the lateral peripheral walls 6 and 10 are raised from their flat position, so that the folding box 2 has a state with an approximately diamond-shaped plan gets into the desired box shape with a rectangular layout. The bottom tabs 70 and 72, glued to one another, and the bottom tabs 74 and 76, on the other hand, extend into the floor level and form a closed, partially multi-layer overlapping bottom, the tab 76 a engaging under the part of the bottom tab 72 close to it, which The main part of the bottom flap 76 , on the other hand, lies over the part of the bottom flap 72 that is close to it, with an additional interlocking of the folding adhesive base also being formed on the bottom flap 72 on the one hand and on the bottom flap 76 on the other hand, when the folding interlocking locking projections 84 and 86 are unfolded .

As can be seen in particular in FIG. 4, the bottom flap 72 is lifted when the folding box 2 is unfolded from the front order wall 4 , on which it previously rested. Since the material strip 38 is glued to the front peripheral wall, the tear-off edge 78 tears off, so that the unfolding of the bottom flap 72 is not hindered.

Since the opening limiting tab 28 in the manner described with reference to FIG. 3 between the adhesive area 61 of the circumferential wall 6 and the overlap adhesive tab 60 is clamped, it is secured against lifting off from the circumferential wall 6 and is consequently when the folding box 2 is unfolded in the direction perpendicular to it Strips of material 38 taken with standing. This measure is necessary because by folding the opening limiting flap by 180 ° its tendency to erect on its own may be lost. When opening the removal flap 24 for the first time, the pinched end 34 is automatically released from the fuse described, so that the opening of the removal flap is not prevented.

Fig. 5 shows a view into the open top of the folding box according to the arrow IV in Fig. 1. For a better overview, the peripheral walls 4 , 6 , 8 and 10 are shown separately from each other, so that even in the unfolded state overlapping several times Bottom tabs 72 , 70 , 76 and 74 are fully visible. According to the explanation to Fig. 3, hatched hatching means that the lower side with respect to the plane of the drawing represents an adhesive surface, while the continuous hatching indicates that the upper side with respect to the plane of the drawing is an adhesive surface. Accordingly, the shaded area 74 is the bottom flap to the flap 76 a of the bottom flap 76 and overlaps therewith in the kon Gruenten hatched areas. The hatched area of the bottom flap 72 lies on the hatched area of the flap 70 a and overlaps with this in the respective hatched areas. As already explained with reference to FIG. 4, in the unfolded state of the box - with reference to FIG. 5 - the tab 76 a and the bottom tab 74 bonded to it grip under the left part of the bottom tab 72 , while the right part of the bottom tab 76 engages over the right part of the base plate 72 and the base plate 70 , 70 a glued to it. The projections 84 , 86 clamp together . The overlap adhesive flap 60 , the material strip 38 and the two opening-limiting flaps 28 , 30 can also be seen in FIG. 5.

It should also be mentioned that the material strip 38 not only serves to hold the opening limitation tabs 28 and 30 , but at the same time forms an advantageous reinforcement of the removal flap 24 .
