Description

Descriptive Report of the Invention Patent for "FOLDING BOX WITH ENHANCED REGION OF ABA AGAINST DUST".

The present invention relates to a folding box made of cardboard, cardboard, synthetic material or similar material having at least two double layer or honeycomb winding bases which can house and protect a product from be packed, especially crucibles.

EP 642977 discloses such a folding box with at least one retaining and protective element for a glass, such as jelly glass or the like, which is formed by an arc of flexible material, especially cardboard, and is It is provided with four adjacent main walls, also including two tilting caps and two closing walls for the respective formation of the two ends of the box, which walls are spaced from the free ends of the main walls and are separated from them by each other. bend lines. Complementary folding lines are provided in each of the tilting caps mentioned, to which other flaps are also articulated by folding lines. These flaps may form a retaining element for the glass to be packed, the flaps being freely rotatable, i.e. tilting, so that they can be placed over at least the tilting lid sections between their line. fold and the complementary fold line, which is located near the adjacent main wall of the folding box, to reinforce the same tilting lid section.

A disadvantage in such embodiments is insufficient stability especially for glass containers, caused particularly by the retaining element, which can only be fixed in one layer or insufficiently to the folding box.

The object of the present invention is to provide a box in the form of a single piece of cardboard or other material, the box being able to unstably retain a product to be packaged, especially in small form, and to effectively protect it.

Another objective is to provide an alternative folding box for the storage and transport of crucible containers. The aim in this particular case is that these folding boxes can be stamped and folded easily at the folding box factory without additional effort.

These objectives are achieved by means of a folding box with reinforced dust flap region according to claim 1.

The foldable 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, as well as in the At least one hinged flap to the left side wall for connection to the rear side wall. The front and / or rear side walls are hinged below, respectively at the top, with closing flaps respectively, to which at least one insertion or gluing flap suitable for the closure.

The left and right sidewalls are hinged underneath and / or above the dust flaps, and at least two of the dust flaps are respectively hinged to four hinged rollers, formed by an outer support flap, an outer support flap, an inner support flap and an inner support flap, respectively, which form the at least two coils, which according to the invention are double layered and supported and / or honeycomb, which surround the product to be packaged.

In this case, the inner support tabs, respectively supporting ones, abut the dust tabs and / or rest on or abut the outer support tabs hinged to the dust tabs. In case the inner support flaps respectively of the support rest on the outer support flap, a double layer winding is formed; if the inner support flaps respectively abut the abutment outer flap and / or the dust flap, a support winding is formed and in the case of the inner abutment flaps respectively abutting the flaps against dust and in the case of an additional backing glue, a honeycomb winding is formed. Moreover, according to the invention, the inner support flaps are divided into at least one respective central flap and a respective segment-flap07-and-central flap is hinged to the outer flap. and can be glued to the inner side of the right and left sidewall by snapping, which is called the central flap bearing glue.

The formation of a honeycomb, double-layered and / or supported winding to support a product to be packaged in combination with the central flap support gluing is a decisive difference and advantage in With respect to the state of the art, at least over the flip-top sections placed above the winding, a double layer must be formed between a fold line and the complementary fold line, which is located near the adjacent main wall. of the folding box to reinforce the same tilting lid section.

Especially due to the formation of a honeycomb and / or supported winding according to the invention, the known double layer of the state of the art is avoided, yet even further reinforced stability of the winding is ensured for storage. and safely transport the products to be packed, such as special glass crucibles.

Moreover, an advantage of the folding box according to the invention is that it can be easily produced in one cut and can be fitted and glued in one work step in a folding box factory.

The foldable box variants according to the invention for packaging a product will be shown in detail by means of figures 1 to 14.

The outward and inward indications, in this case, refer respectively to the formed windings.

According to Figure 1, the folding box according to the invention comprises four side walls forming the body of the box, one being a front side wall (3), a rear side wall (1), a right side wall (2) and a left side wall (4), and at least one connecting tab (5) hinged to the left side wall (4) for connection to the rear side wall (1). The left, right, front or rear side wall designations, as well as the following orientation references, such as outer, inner, etc., are for clarification only. Equivalent configurations are also encompassed according to the invention.

The front and / or rear sidewalls (1, 3) are hinged at the bottom, respectively at the top, by the bottom flaps (11,31, 31 ') respectively, which are also in turn arranged. if at least one insertion or gluing flap (12, 32, 32 ') suitable for closure is hinged. These tabs form the basic body that can also be enclosed in a cubic folding box.

The left and right side walls (2, 4) are hinged underneath and / or above, dust flaps (2-1, - 41), with at least two of the dust flaps (21, 41) being four hinged winding tabs, respectively, formed by external support tabs (22, 42), external support tabs (23, 43), internal support tabs (24, 44) and tabs. (25, 45) which form at least two double layer (fig. 7), honeycomb (fig. 12) or supported (fig. 14 d) windings surrounding the product to be packaged.

The folding box surrounds the product in the lid and / or bottom region in a protective manner by means of the folding and extended winding tabs (22, 23, 24, 25, respectively 42, 43, 44, 45) when they are two windings (A, B) are formed, and additionally by means of the winding tabs (22 ', 23', 24 ', 25', respectively 42 ', 43', 44 ', 45') (windings C, D ) when a total of four windings protecting the product are to be formed (cf. figures 1, 2 and 8).

By means of suitable folding and gluing, therefore, the double-layer according to the invention are preferably important regions of the winding which are the areas shown in figures 3, 24a, 24b with 23 and 44a. , 44b to 43, as well as areas 25, 45, 25 ', 45' over 22, 42, 22 ', 42'.

As the inner support or support tabs (25, 45) rest on the outer support tabs (22, 42) hinged to the dust tabs (21, 41), it becomes possible to form a coil - double layer design (Figures 4, 7). The inner support flaps (24, 44) are respectively divided into at least one central flap (26, 46) and a segment flap (24a, 24b, respectively 44a, 44b), and the central flaps (26 , 46), which are hinged to the outer support flaps (23,43), are glued to the inner side of the right and left side walls (2, 4). This provides the central flap support glue (fig. 7) according to the invention. Alternatively, the inner support flaps 25, 45 may not rest inwardly on the outer support flaps 22,42, be advantageously glued thereto and form a double layer coil (Fig. 14b), otherwise, As shown in Figs. 14 d, e and f, they may abut the interlocking between the outer support tabs (22, -42) and the dust tabs (21, 41), they may abut against the outer support tabs (22, 42). ) or the dust flaps (21, 41) (Figure 14e, 14f) depending on the length of the inner support flaps (25, 45). In such embodiments of the folding boxes according to the invention a so-called supported winding is obtained and the inner support flaps (25, 45) are advantageously referred to as internal support flaps.

When the flaps (24 on 23, 25 on 22 and 44 on 43, 45 on 42, as well as the corresponding flaps ') which preferably have become a surface are turned, then the central areas (26, 46, 26' 46 ') can be glued to the folding box body (areas 2 + 4) (Figures 4, 5, 6, 7). Advantageously, for this there is provided at least one collection point (6) on the central flap (26, 46, 26 ', 46') (Figures 5, 6 and 11). Depending on whether the glue point is applied to the center flap externally or internally and whether the center flaps are snapped in or out, an outwardly directed center flap support bonding results (Figures 7, 8, 12b, 13b , 14a-f) or inwardly directed (Figures 12a, 13a, 14g). In this way, after lifting the winding, a bridging connection is obtained, as shown in Figure 7, respectively. 8. According to this alternative, within the winding a double layer (double layer winding) area (tabs) has been created. 22, 42 with 25, 45, as well as tabs 23, 43 with 24a, 44a, respectively 24b, 44b), which act as a support and as a fixation on the product to be packaged and especially surrounds a bottom region, respectively of lid of the crucible.

The advantage of this winding is the high stability in the bearing region of the winder. The product is firmly held up and / or down by means of a double layer cardboard area such that high product safety is ensured. This essentially leads to the stability of a packed crucible, which is not obtainable in the case of state-of-the-art folding boxes.

According to the invention, as an additional variant a profile-shaped stamp can also be incorporated into the bottom or cover region of the winding, as shown in Figures 2, 6 and 8, of areas 230 + 430, with that the cutting profile (231 + 431) is adapted to the container. The folding box then comprises at least two of the outer support tabs (22, 42, 22 ', 42') and inner support tabs (25, 45, 25 ', 45') and / or outer supports (23, 43, 23 ', 43'), a stamping (230, 231, 430, 431) in profile form adapted to the product to be packaged.

The folding crucible box can also have a window stamping (3a) adapted to the product, in which case the most different embodiments can be assumed. Then, in at least one of the side walls (1, 2, 3, 4) there is a stamping (3a), which makes the product to be packed identifiable from the outside (figure 1).

The bases (winding A, B, C respectively D) created by the windings and glues can reach all dust flaps, respectively only at the lower two (21, 41) or the upper two (21 ', 41' ).

Thus, the folding box preferably comprises on the left and right side walls (2, 4), below and above, dust flaps (21, 21 ', 41, 41'), with the all dust flaps (21, 21 ', 41, 41') are respectively hinged to four hinged winding tabs formed by external support tabs (22, 42, 22 ', 42'), external support tabs (23, 43, 23 ', 43'), inner support flaps (24, 44, 24 ', 44') and inner support flaps (25, 45, 25 ', 45'), which form four layer windings double (A, B, C, D) involving the product to be packed.

Preferably, the folding box comprises four inner support flaps (24, 44, 24 ', 44'), which are respectively divided into at least one central flap (26, 46 ', 26', 46 ') and one respectively, segment flap (arb) (24a, 24b, 44a, 44b, 24a ', 24b', 44a ', 44b')] where the central flaps (26, 46, 26 ', 46') are hinged to the outer support flaps (23, 43, 23 ', 43') and can be glued together on the inner side of the right and left side walls (2, 4).

The windings and embossing (3a) are preferably arranged in a one-way way so that it is possible to see a product completely and the embossing (3a) is arranged between the formed windings (A, B, C, D).

The lengths of the respective flap areas (22, 25, 42, 45, 22 ', 25', 42 ', 45'), as can also be seen from figures 1, 2, 7 or 10, may differ from each other. . They are always adapted to the product and the size of the folding box and thus also form different winding heights. By length of a tab here is meant the distance between the tabs hinged to the adjacent tab; thus, for example, the lengths of the inner support flaps (24, 44) are the distances between the outer support flaps (23, 43) and the inner support flaps (25, 45).

As a particularly preferred alternative, as discussed above, it is possible to vary the lengths of the inner support flaps (25, 45, 25 ', 45') so that they do not form a double layer support area with the support flaps. outer supports (22, 42, 22 ', 42'), but do touch the dust flaps (21, 41, 21 ', 41') or the support flaps (22, 42, 22 ', 42') internally, as shown particularly by FIGS. 14d, e, and FIG. 10. The inner support flaps, now support flaps (25, 45, 25 ', 45') can act as a support from within, for example, diagonally into the folding of the dust flaps (21, 41, 21 ', 41') and the support flaps (22, 42, 22 ', 42'). This also provides greater winding support with respect to the product. This embodiment is called a folding box with suitable winding.

Thus, the length of the inner support flaps (25, 45) may be the same as the length of the outer support flaps (22, 42) depending on the length of the inner support flaps (24, 44), - and thus the winding formation according to figures 7, 12, 14 a, b or c. However, it may also be shorter, respectively longer, than the length of the outer support flaps 22, 42 and thus the winding construction according to FIGS. 14 d, e or f is obtained.

Another preferred embodiment of the foldable box according to the invention is obtained when the inner support wings, respectively internal support wings (25, 45), in the case of the formation of two windings (A, B), or on the inner support tabs, respectively inner support tabs (25, 45, 25 ', 45'), when four windings (A, B, C, D) are formed, other tabs are articulated support or gluing (27, 47) in the case of the formation of two windings, respectively (27, 47, 27 ', 47') in the case of the formation of four windings (see Figure 9).

By shortening the length of the inner support flaps (24, 44, 24 ', 44'), respectively segment flaps (24a, 24b, 24'a, 24'b, 44a, 44b, 44'a , 44'b), as shown in figures 9, 11, 12, 13 and 14a, and of the articulation of the other support or glue tabs (27, 47), respectively (27, 47, 27 ', 47') an additional supporting support is created which divides the winding into two chambers and is called the preferred honeycomb embodiment according to the invention (Figures 12, 13). This results in greater rigidity and stability of the double layer winding of the support area. Thus, the required solution of the problem of better protecting the product within the package is also achieved by this preferred embodiment.

In the subsequent folding box lifting processes, as shown in figures 11, 11a and 11b, the other support flaps (27, 47, 27 ', 47'), depending on the respective length of the internal support flaps ( 24, 44, 24 ', 44'), respectively of the segment flaps (24a, 24b, 24'a, 24'b, 44a, 44b, 44'a, 44'b), are placed inside over the flaps of outer supports (22, 42, 22 ', 42') and, when lifting, they are glued to the dust flaps (21, 41, 21 ', 41 "), preferably by adhering surfaces (6b) Another retention of the thus produced honeycomb coil is obtained by taking off the segment flaps (24a, 44a, 24b, 44b, respectively 24a ', 44a', 24b ', 44b') by means of glue points (6a). on the tabs (23, 43, 23 ', 43') In the preferred embodiments shown, with the additional support tabs (27, 47) or with the extended support tabs (25, 45), the support tabs (24, 44) respectively the segment flaps (24a, 24b, 44a, 44b) are shortened such that initially the preferred winding constructions shown in Figures 14a, 14c, 14d, 14e, 14f and 14g can be formed. In this case, correspondingly the central flaps (26, 26 ', 46, 46') are also shortened.

Preferably, the lengths of the inner support flaps (24, 44), respectively (24 ', 44'), and / or the segment flaps (24a, 44a, 24b, 44b), respectively (24a ', 44a', 24b ', 44b') must be 0.9 to 0.1 shorter than the length of the outer support flaps (23, 43), respectively (23 ', 43'). It is especially advantageous that the lengths of the inner support wings, respectively inner segment flaps (24, 44), are 0.5 to 0.1, especially 0.3 to 0.1, shorter than the lengths. external support flaps (23, 43), respectively (23 ', 43'). If the lengths of the flaps 25, 45 and 23, 43 are equal (1: 1 ratio), then the variant according to figure 7, respectively 14b, will result.

Alternatively, the additional support flaps (27, 47, 27 ', 47') may be placed inside and preferably glued to the external support flaps (21, 41, 21 ', 41') towards the side wall. (2) (Figure 14c) or towards the outer support tabs (22, 42, 22 ', 42') (Figure 14a). This results in bonding of the support flaps designated as inwardly directed (Figure 14c), respectively as outwardly directed (Figure 14a, 14g).

Collapsible box collages can be made in the collapsible box factory. In such a case, preferably the outermost areas (figure 3) 25, 45, 25 ', 45', with the areas 24b, 44b, 24'b, 44'b, respectively 24a, 44a, 24 ' a, 44'a, over 22, 42, 22 ', 42' are placed inwards and are glued as shown in figures 3, 4 and 5.
