Description

Folding box with reinforced dust flap area

The invention relates to a carton, cardboard, plastic or similar material created carton with at least two double-layered or honeycomb-like winding sockets, which can accommodate and secure a product to be packaged, especially crucibles.

EP 642977 discloses such a carton having at least one holding and protecting element for a glass, such as a jam jar or the like, formed from a sheet of flexible material, in particular cardboard, and provided with four successive main walls, further comprising two flaps and to form the two ends of the box with two respective closure walls which protrude from the free ends of the main walls and are separated therefrom by fold lines. At each of the mentioned flaps complementary fold lines are provided, to which in turn are hinged on fold lines more tabs. These tabs can form a retaining element for the glass to be packaged, the tabs being freely rotatable, i. hinged to be laid on at least the flap portions between its fold line and the supplementary fold line which is closer to the adjacent folding box main wall to stiffen the same flap portion.

A disadvantage of these embodiments is an insufficient in particular for glass containers stability, which is caused in particular by the holding element, which can be attached to the carton only single or insufficient.

The object of the present invention is to provide a carton in the form of a single piece of cardboard or other material, the carton being capable of stably holding and effectively protecting a product to be packaged, particularly in crucible form, within the carton.

Another object is to provide an alternative carton for storing and transporting crucible-shaped containers.

Task here is in particular that these cartons can be easily punched and folded in folding carton without any additional effort.

The objects are achieved by a folding box with reinforced dust flap area according to claim 1.

The folding box according to the invention for packaging a product comprises four side walls forming the box body, a front side wall, a rear side wall, a right side wall and a left side wall and at least one on the left

Sidewall hinged connection tab for connecting to the back wall.

At the front and / or rear wall are below or above floor or

Hinged closure tabs, to which in turn at least one plug-in or gluing tab suitable for closing is articulated.

On the left and right side walls are attached at the bottom and / or top dust flaps, with at least two of the dust flaps each four hinged to each other

Wrap tabs, formed from outer support tab, outer support tab, inner

Support tab and inner support or support tab are hinged, forming at least two surrounding the product to be packaged invention, two-ply, supported and / or honeycomb-like winding.

The inner support or support tabs are on the dust straps and / or on the

Dust tabs hinged on or on outer support tabs. When resting the inner

Support or support tabs on the outer support tab forms a double-layered

Winding, the concern of the inner support or support tabs on the outer support tab and / or on the dust flap forms a supported winding and when concerns the inner support or support tabs on the dust straps and additional Stützverklebung forms a honeycomb-like winding.

Furthermore, according to the invention, the inner support tabs are in at least one each

Center strap and one web tab each divided and the center strap is on the outer

Support tab hinged and can be folded on the inside of the right and left

Side wall are glued, which is referred to as Mittellaschenstützverklebung.

The formation of a honeycomb, two-ply and / or supported coil for supporting a product to be packaged in combination with the center flap support bonding is a significant difference and advantage over the prior art by providing at least on the overlying flap portions of the roll a double layer between a fold line and the complementary Folding line must be formed, which is closer to the adjacent Faltschachtelhauptwand to stiffen the same flap section.

In particular, by the formation of a honeycomb-like and / or supported coil according to the invention, the double layering known from the prior art is avoided but nevertheless ensures increased stability of the coil in order to safely store and transport products to be packed, in particular glass crucibles. Another advantage of the carton according to the invention is that it can be easily produced in one cut and folded in a folding carton in one operation and glued.

The information outside and inside refer to each case on the formed coils.

According to FIG. 1, the folding box according to the invention comprises four side walls forming the box body, a front side wall (3), rear side wall (1), right side wall (2) and left side wall (4), and at least one connection tab (5) articulated on the left side wall (4) ) for connection to the rear wall (1). The designation as left, right, front or rear side wall as well as subsequent orientation information, such as outer, inner, etc., serve only for clarification. Equivalent transformations are also included according to the invention. Bottom or Veschlusslaschen (1 1, 31, 31 ^' ) are hinged to the front and / or rear side wall (1, 3), to which in turn at least one plug-in or gluing tab (12, 32 , 32 ^' ) is articulated. These tabs form the reclosable basic body of a cuboid carton.

On the left and right side walls (2, 4) below and / or above are hinged flaps (21, 41), wherein at least two of the dust flaps (21, 41) in each case four mutually hinged winding flaps formed of outer support tab (22, 42 ), outer support tab (23, 43), inner support tab (24, 44), and inner support or support tab (25, 45)) hinged to cover at least two two-ply (FIG. 7), honeycomb-like (FIG. Fig. 12) or supported windings (Fig. 14d) form. The carton envelops the product in the lid and / or bottom area protectively by the foldable extended winding tabs (22, 23, 24, 25 or 42, 43, 44, 45) when two coils (A, B) are formed and additionally by the winding tabs (22 ', 23', 24 ', 25 ^' or 42 ', 43', 44 ', 45 ^' ) (reels C, D) if a total of four reels securing the product are to be formed (see FIG , 2 and 8).

By corresponding folding and bonding are thus inventively preferred important areas of the coil, the surfaces shown in Figure 3 24a, 24b with 23 and 44a, 44b with 43 and surfaces 25, 45, 25 ', 45' on 22, 42, 22 '. , 42 'double-layered.

By the inner support or support strap tabs (25, 45) lie folded on the outer abutment tabs (22, 42) hinged to the dust flaps (21, 41), a double-layered winding can form (Figure 4.7). The inner support tabs (24, 44) are subdivided into at least one middle tab (26, 46) and one tab (24a, 24b or 44a, 44b) and the center tabs (26, 46) attached to the outer tabs (23 , 43) are glued by folding on the inside of the right and left side wall (2, 4). This results in the middle flap support bonding according to the invention (FIG. 7). Alternatively, the inner support tabs (25, 45) can not rest on the outer support tabs (22, 42) from the inside, be glued to them advantageously, and form a two-ply turn (Figure 14b) but, as shown in Figure 14d, e and f, lie in the fold between the outer support tabs (22, 42) and the dust flaps (21, 41), supporting the outer support tabs (22, 42) or the dust tabs (21, 41) (Figure 14) e, f), depending on how the length of the inner support tab (25, 45) is selected. In these embodiments of the folding boxes according to the invention results in a so-called. Supported winding and the inner support tabs (25, 45) are advantageously referred to as inner support tabs. When the preferred to a surface become tabs (24 to 23, 25 to 22 and 44 to 43, 45 to 42 and in accordance with the ^tabs') (46 ', with the carcass are folded, the central surfaces 26, 46, 26) can' the folding box (surfaces 2 + 4) are glued (Figure 4, 5, 6, 7). Advantageously, at least one adhesive point (6) on the middle tab (26, 46, 26 ', 46') provided (Figure 5, 6 and 1 1). Depending on whether the adhesive dot on the center flap is applied externally or internally and the center flaps are folded inwards or outwards, an outwardly directed (FIG. 7, 8, 12b, 13b, 14a-f,) or inwardly directed (FIG. Figure 12 a, 13 a, 14 g) Center flap support bonding. This results in a bridge-like connection after erection of the roll, as shown in FIGS. 7 and 8, respectively. In the interior of the roll according to this alternative, a double-layered surface (double-layered winding) (tabs 22, 42 with 25, 45 and tabs 23, 43 with 24a, 44a and 24b, 44b) has been created, the supporting and fixing to be packaged Work well and in particular encase a Tiegelboden- or crucible cover area.

Advantage of this winding is the high stability in the supporting area of the coil. The product is held firmly by a two-ply board surface upwards and / or downwards, so that a high product security is guaranteed. This substantially contributes to the stability of a packed crucible, as can not be achieved by folding cartons of the prior art.

As an additional variant, according to the invention also in the bottom or top region of the coil a contour-like punching, as shown in Figures 2, 6 and 8, surfaces 230 + 430, are incorporated, wherein the sectional contour (231 + 431) is adapted to the container. The carton then comprises at least two of the outer support tabs (22, 42, 22 ^' , 44 ^' ) and inner support tabs (25, 45, 25 ^' , 45 ^' ) and / or the outer support tabs (23, 43, 23 ^' , 43) ^' ) a contour-like cutout adapted to the product to be packaged (230, 231, 430, 431).

The crucible folding box can also have a window cut-out (3a) adapted to the product, whereby very different embodiments can be used here. Then, in at least one of the side walls (1, 2, 3, 4) a punched-out (3a) is present, which makes the packaging product visible from the outside (Figure 1).

The sockets (wraps A, B, C or D) created by windings and adhesions can be attached to all or even only to the two lower (21, 41) or the two upper (21 ^' , 41 ^' ) dust flaps. Thus, the folding box preferably comprises at the left and right side walls (2, 4) at the bottom and at the top stacks of flaps (21, 21 ^' , 41, 41 ^' ), with four at each of the stacks (21, 21 ^' , 41, 41 ^' ) articulated roll tabs formed of outer support tabs (22, 42, 22 ^' , 44 ^' ), outer support tabs (23, 43, 23 ^' , 43 ^' ), inner support tabs (24, 44, 24 ^' , 44 ^' ), and inner support tabs (10; 25, 45, 25 ^' , 45 ^' )) are articulated, the four surrounding the product to be packaged double-layered winding (A, B, C, D).

Preferably, the carton comprises four inner support tabs (24, 44, 24 ^' , 44 ^' ) which are in at least one middle tab (26, 46, 26 ^' , 46 ^' ) and one or two web tabs (a, b) (24a , 24b, 44a, 44b, 24a ^' , 24b ^' , 44a ^' 44b ^' ), wherein the middle tabs (26, 46, 26 ^' , 46 ^' ) on the outer support tabs (23, 43, 23 ^' , 43 ^' ) hinged and can be glued by folding on the inside of the right and left side wall (2, 4).

The winding and the punch-out (3a) are preferably arranged so that a product can be seen completely and the punched-out portion (3a) is arranged between the formed coils (A, B, C, D).

The lengths of the surfaces or tabs (22, 25, 42, 45, 22 ', 25', 42 '45',) as well as in the figures 1, 2, 7 or 10 visible) may be of different lengths. They are always adapted to the product and the size of the carton and thus form different heights of the wrap. The length of a tab is hereby considered to be the distance between the hinged tabs adjacent to the tab, e.g. the lengths of the inner support tabs (24, 44) are the distances between the outer support tabs (23, 43) and the inner support tabs (25, 45).

As a particularly preferred alternative, as previously stated, the inner support tabs (25, 45, 25 ^' , 45 ^' ) may be varied in length so that they do not have a two-ply bearing surface with the outer support tabs (22, 42, 22 ^' , 42) ^' ), but on the inside of the dust flaps (21, 41, 21 ^' , 41 ^' ) or on the support tabs (22, 42, 22 ^' , 42 ^' ) rest, as shown in particular by the figures 14 d, e, f and Figure 10 is shown. The inner support, now support tabs (25, 45, 25 ^' , 45 ^' ), for example, diagonally into the fold of the dust flaps (21, 41, 21 ^' , 41 ^' ) and support tabs (22, 42, 22 ^' , 42 ^' ) to support from the inside. This also achieves an increased support of the coil to the product. This embodiment is referred to as a carton with supported winding. The length of the inner support tabs (25, 45) can thus, depending on the length of the inner support tabs (24, 44), be equal to the length of the outer support tabs (22, 42) and the winding formation according to Figures 7, 12, 14 is obtained a, b or c. But it can also be shorter or longer than the length of the outer support tabs (22, 42) and you get the winding structure according to Figure 14 d, e or f.

A further preferred alternative embodiment of the carton according to the invention is obtained if on the inner support or support tabs (25, 45), in the formation of two coils (A, B) or the inner support or support tabs (25, 45, 25 ^' , 45 ^' ), when four coils A, B, C, D) are formed, further support or adhesive tabs (27, 47), in the formation of two coils, or (27, 47, 27 ^' , 47 ^' ) in the formation of four windings, articulated (see Figure 9).

By shortening the length of the inner support tabs (24, 44, 24 ^' , 44 ^' ) and web tabs (24a, 24b, 24'a, 24'b, 44a, 44b, 44'a, 44'b), as in Figures 9, 1 1, 12, 13 and 14 a shown, and the articulation of the other support or Verklebungslaschen (27, 47) or (27, 47, 27 ^' , 47 ^' ) is provided an additional support support, the Winding is divided into two chambers and referred to as inventively preferred honeycomb-like embodiment (Figure 12, 13). As a result, an increased rigidity and stability of the winding is achieved without double layer of the support surface. Thus, the required problem solving to better protect the product inside the package is also solved by this preferred embodiment.

In the later Aufrichteprozessen the carton, as Figure 1 1, 1 1 a and b represent, the other support tabs (27, 47, 27 ^' , 47 ^' ), depending on the length of the inner support tabs (24, 44, 24 ^' 44 ^' ) and web tabs (24a, 24b, 24'a, 24'b, 44a, 44b, 44'a, 44'b) are placed inside the outer support tab (22, 42, 22 ^' , 42 ^' ) and at Erecting preferably glued by means of adhesive surfaces (6b) on the dust flaps (21, 41, 21 ^' , 41 ^' ). Further retention of the resulting honeycomb-like winding is achieved by gluing the web tabs (24a, 44a, 24b, 44b or 24a ^' , 44a ^' , 24b ^' , 44b ^' ) onto the tabs (23, 43, 23 ^' , 43 ^' ).

In the illustrated preferred embodiments with the additional support tabs (27, 47) or the extended support tabs (25, 45), the inner support tabs (24, 44) or web tabs (24a, 24b, 44 a, 44b) are shortened, so that only the, as shown in Figures 14 a, c, d, e, f and g shown preferred winding structures can form. Correspondingly, the middle straps (26, 26 ', 46, 46') are shortened as well. It is preferred if the lengths of the inner support tabs (24, 44) or (24 ^' , 44 ^' ) and / or web tabs (24a, 44a, 24b, 44b) and (24a ^' , 44a ^' , 24b ^' , 44b ^' ) are 0.9 to 0.1 shorter than the length of the outer support tabs (23, 43) and (23 ^' , 43 ^' ), respectively. In particular, it is advantageous if the lengths of the inner support or web tabs (24, 44) by 0.5 to 0.1, in particular by 0.3 to 0.1, shorter than the lengths of the outer support tabs (23, 43 ) or (23 ^' , 43 ^' ). If the lengths of the tabs (25, 45) and (23, 43) are the same (ratio 1: 1), the variant results according to Figure 7 or 14 b.

Alternatively, the additional support tabs (27, 47, 27 ^' , 47 ^' ) from the inside to the outer support tabs (21, 41, 21 ^' , 41 ^' ) in the direction of the side wall (2) (Figure 14c) or in the direction of the outer support tabs (22, 42, 22 ^' , 42 ^' ) (Figure 14a) are applied and preferably glued. This results in the so-called inwardly directed (Figure 14 c) or outward directed (Figure 14 a, g) Stützlaschenverklebung.

The gluing of the folding boxes can be done in the folding carton plant. In this case, the outer surfaces (FIG. 3) 25, 45, 25 ', 45', with the surfaces 24b, 44b, 24'b, 44'b, and 24a, 44a, 24'a, 44'a, respectively, are preferably referenced to 22 , 42, 22 ', 42', as shown in Figures 3, 4 and 5, placed inside and glued.
