Description

The The invention relates to a two-part packaging made of folding material with a bottom and side walls having lower Packing part and a side walls having upper Packaging part, wherein to form a common packaging the two packaging parts are inserted into each other, at least overlap with a mounting portion of its side walls in an overlapping area and there detachable by at least one attachment point connected to each other.

at Such a two-part packaging are the first lower packaging part and the upper packaging part together connected and form for receiving suitable articles a substantially closed packaging. In this essentially closed Condition, the packaging is also usually transported, so that during transport the ones contained in the packaging Articles are protected accordingly. At the place of sale you solve the connection between the two packaging parts. As a result, the items contained in the packaging for the sale freely accessible; because they are in the lower one Packing part, which remains after removing the obe ren packaging part and as a tray-shaped packaging for the presentation the article serves.

From the DE 43 25 431 A1 For example, a two-part packaging is known in which for releasing the connection are provided externally accessible fastening tabs which are detachably connected via parting lines with the respective wall, so that when releasing the compounds by pulling the fastening tabs, the two packaging parts can be separated , The fastening tabs are formed as upwardly facing extensions of the adjacent side walls and connected to each other via a connecting panel which adjoins the upper edges of the side walls via a cutting line.

at the conventional constructions led the separation process to impairments of the lower packaging part, the showed up at least in the form of a visible spoiler lip. The occurrence of such impairments on the lower packaging part is a disadvantage especially when using high quality materials, whose purpose consists in an optimal presentation.

It is the object of the present invention, for a two-part Packaging of the type mentioned above to propose a construction, in which the separation process to no impairment the lower packaging part leads and which also offers a simple structure and easy handling.

These Task is solved by a two-part packaging Folding material having a bottom and side walls lower packaging part and a side walls having upper Packaging part, wherein to form a common packaging the two packaging parts are inserted into each other, at least overlap with a mounting portion of its side walls in an overlapping area and there detachable by at least one attachment point interconnected, characterized in that at least a side wall of the upper packaging part with the at least one Fastening portion inside on a side wall of the lower packaging part is located and the at least one mounting portion of the upper packaging part detachable with the remaining portion of the upper packaging part and firmly connected to the lower packaging part and from the lower Packaging part is completely covered.

preferred Embodiments and developments of the invention are in specified in the dependent claims.

With the help of the construction according to the invention, a separation process can be realized, which leads to no impairment of the remaining for the presentation of the article lower packaging part. This is inventively achieved in that the upper packaging part is fixed to the inside of the lower packaging part by means of at least one attachment portion which is fixed inextricably on the inside of the lower packaging part, but releasably connected to the remaining portion of the upper packaging part and also from the lower packaging part completely covered. During the separation process, the attachment portion is detached from the upper packaging part and remains on the inside of the lower packaging part. The separation process therefore does not take place directly between the lower packaging part and the upper packaging part, but between the fastening section attached to the inside of the lower packaging part and the remaining part of the upper packaging part. This ensures that the lower packaging part is not affected by the separation process in any way. In particular, no tear-off edge or other cut contour is formed at the lower part of the package. Since the attachment portion is not only fixed to the inside of the lower packaging part, but is completely covered by this, he remains invisible after the separation process. Thus, neither mechanical nor visual impairments occur on the lower packaging part after loosening the upper packaging part. This is particularly advantageous if for the lower Packaging part can be used for the purpose of optimal presentation of high quality materials.

Furthermore offers the construction of the invention a simple design and easy handling, which is suitable for makes the separation process also beneficial noticeable.

following is a preferred embodiment of the invention explained in more detail with reference to the accompanying drawings. Show it:

1 in a separate representation, a blank for a lower packaging part and a blank for a top packaging part to form a two-part package;

2 the blank for the lower packaging part and the blank for the upper packaging part in a connected arrangement to form the two-part packaging;

3 in a fragmentary enlarged view of a portion of the arrangement of 2 in the area of a splice; and

4 a 3 corresponding representation in which the upper packaging part is detached from the lower packaging part.

As the 1 and 2 can be seen, a two-part packaging shown there has a lower packaging part 2 and an upper packaging part 4 on, with the 1 and 2 for the lower packaging part 2 and the upper packaging part 4 each show a corresponding cut.

The blank for the lower packaging part 2 has two long side wall sections 6 passing through an upper free edge 6a are limited, and two narrow side wall sections 8th extending transversely to the longitudinal extent of the long side wall sections 6 running fold lines 10 with the long side wall sections 6 are connected. At the one end (according to 1 Right) located narrow side wall section 8th is about one of the fold lines 10 parallel folding line 12 a glue flap 14 hinged. At its side away from the upper free edge side are the two long side wall sections 6 and narrow side wall sections 8th from a straight, continuous fold line 16 limited, over on the long side wall sections 6 and the narrow side wall portions 8th one bottom flap each 18 is articulated.

The blank for the upper packaging part 4 has two long side wall sections 20 , each by a lower free edge 20a are limited, and two narrow side wall sections 22 on, which also each by a lower free edge 22a limited and across the longitudinal extent of the long side wall sections 20 running fold lines 24 with the long side wall sections 20 are hingedly connected. The lower free edges 20 . 22a the long side wall sections 20 and narrow side wall sections 22 lie on a straight line. In particular 1 can recognize, have the long side wall sections 20 and the narrow side wall portions 22 of the upper packaging part 4 the same dimensions in the longitudinal direction as the long side wall sections 6 and the narrow side wall portions 8th of the lower packaging part 2 so the fold lines 24 of the upper packaging part 4 with the fold lines 10 of the lower packaging part 2 essentially aligned. The same applies to one at the one (according to 1 right) end of the blank of the upper packaging part 4 trained fold line 26 over which a glue flap 28 on the adjacent narrow side wall section 22 hinged, in relation to the fold line 12 of the lower packaging part 2 , At the bottom of the free edge 20a respectively. 22a remote side are the long side wall sections 20 and the narrow side wall portions 22 through a straight, continuous fold line 30 bounded at a distance parallel to the lower free edges lying on a straight line 20a and 22a the long side wall sections 20 and narrow side wall sections 22 runs and over to the long side wall sections 20 and the narrow side wall portions 22 one lid flap each 32 is articulated.

When Material for the blanks described above becomes common Cardboard and especially corrugated cardboard used. in principle are of course but other types of material conceivable, if this is foldable material.

The lower packaging part 2 and the upper packaging part 4 are in the state of delivery to a two-piece packaging overlapping connected. This is in 2 which, moreover, also shows that in the connected state, as previously mentioned, the fold lines 10 and 24 such as 12 and 26 aligned with each other. The same applies to the free side edge section 6b the one on the other (according to 2 left) end of the blank for the lower packaging part 2 located long side wall section 6 opposite the free side edge section 20b also on the other (according to the figure left) end of the blank for the upper packaging part 4 located long side wall section 20 ,

As 2 further, overlap the long side wall sections 6 and the narrow side wall portions 8th of the lower packaging part 2 from the outside the lower part of the long side wall sections 20 and the narrow side wall portions 22 of the upper packaging part 4 so that the upper part of the packaging 4 with the upper part of its long side wall sections 20 and its narrow side wall sections 22 over the lower packaging part 2 sticks out.

For connection to the lower part of the packaging 2 In the illustrated embodiment, each of the two long side wall sections 20 of the upper packaging part 4 a fixing section 34 on which part of the corresponding long side wall section 20 is. About two spaced apart and serving as dividing lines perforations 36 that the attachment section 34 Limit to its two sides is the attachment section 34 with the remaining part of the associated long side wall section 20 releasably connected. The two perforation lines 36 run approximately transversely to the longitudinal extent of the long side wall sections 20 and flow into their lower free edge 20a so that the attachment section 34 a lower free edge 34a has, the part of the lower free edge 20a the associated long side wall portion 20 is. In the illustrated embodiment, the two attachment portions 34 a transverse to the longitudinal extent of the long side wall sections 20 extending elongated trapezoid shape. On the outside of each attachment section 34 is a splice 38 educated. The attachment sections 34 are at their bottom free edge 34a remote side by an upper free side edge 34b limited to the one in the associated long side wall section 20 trained finger or handle hole 40 connects so that the top free margin 34b of the attachment section 34 a part of the grip hole 40 forming bordering edge. As in the rest of the 1 and 2 can also be seen, runs in the illustrated embodiment, the upper free side edge 34b the attachment sections 34 parallel to their lower free margin 34a or the lower free margin 20a the long side wall sections 20b and also to the fold line 30 of the upper packaging part 4 ,

As 1 can recognize, in the illustrated embodiment, each of the two long side wall sections 6 of the lower packaging part 2 also a splice 42 on, which is provided on the side, which after completion of the lower packaging part 2 with the help of a later to be described folding process, the inside of the lower packaging part 2 forms while the splices 38 on the side of the upper packaging part 4 are provided, which after completion of the upper packaging part 4 by the folding process, the outside of the upper packaging part 4 forms.

To achieve the in 2 As shown supply state becomes the blank for the lower packaging part 2 with its in the folded state later forming the inner side on the later in the folded state later forming the outer side of the blank for the upper packaging part 4 placed so that the splices 38 . 42 cover each other and connect with each other. For this purpose, optionally only one or both splices 38 . 42 be provided with adhesive. It is also conceivable, instead of the punctiform or circular configured in the figures splices 38 . 42 also essentially the entire attachment section 34 to coat with adhesive. Furthermore, it is conceivable to provide other mounting options than a bond. The decisive factor is that the upper packaging part 4 only with the fixing sections 34 on the lower part of the packaging 2 is fastened, wherein the purpose of such attachment will be explained in more detail below.

As 2 can also be seen, are the lower packaging part 2 and the upper packaging part 4 to be arranged such that the lower free edge of the upper packaging part 4 coming from the lower free edges 20a the two long side wall sections 20 and the lower free edges 22a the two narrow side wall sections 22 is formed and lies on an imaginary straight line, with the lower part of the packaging 2 existing fold line 16 coincides, about which in the lower part of the packaging 2 the bottom flaps 18 with the long side wall sections 6 and the narrow side wall portions 8th are connected. Like a comparison of 2 With 1 is the height of the attachment sections 34 , that is, the distance between its lower free edge 34a and its upper free edge 34b so dimensioned that in the connected state or delivery state according to 2 the attachment sections 34 preferably not over the top free edge 6a the long side wall sections 6 of the lower packaging part 2 protrude and thus the upper free edge 34b the attachment sections 34 possibly below the upper free edge 6a the long side wall sections 6 is or at most coincides with this. However, with this arrangement, you should definitely make sure that the grip holes 40 in the upper part of the packaging 4 at least to a greater extent, if not completely, beyond the lower packaging part 2 and thus beyond the upper free edge 6a the long side wall sections 6 lie to be freely accessible. Finally, the splices need to 38 . 42 be positioned so that they are connected Touch state, like 2 can also recognize.

As already mentioned, shows 2 although one from the lower part of the packaging 2 and the upper packaging part 4 assembled two-piece packaging; however, the in 2 shown two-piece packaging in a delivery state forming unfolded state in which it is still spread in the blank plane and thus forms a kind of flat part. Only by a corresponding folding process, the two-part packaging for their use is completed. For this, a folding takes place at each of the coincident fold lines 10 . 24 around 90 °. This creates a cuboid body, which by gluing the adhesive tabs 14 . 28 facing the adjacent narrow side wall sections 8th . 22 at the fold lines 12 . 26 also be folded by 90 °, with the free side edge sections 6b . 20b the now adjacent long side wall sections 6 . 20 , In the illustrated embodiment, the folding takes place in such a way that the lower packaging part 2 forms the outside of the two-piece package. Furthermore, the bottom flaps 18 at the fold line 16 opposite the long side wall sections 6 and the narrow side wall portions 8th folded inwards by 90 ° and together form a bottom of the two-piece packaging, with the fold line 16 now the bottom edge of the lower packaging part 2 represents. Also, the lid flaps 32 opposite the long side wall sections 20 and the narrow side wall portions 22 of the upper packaging part 4 90 ° at the fold line 30 folded inwards and together form a lid of the two-piece package. In this context, it is of course assumed that the two-part packaging then closed on all sides was previously filled with suitable articles. Alternatively, it is also conceivable, the lid flaps 32 leave out and have the packaging open.

At the point of sale, the connection between the two packaging parts is broken 2 . 4 and takes the upper part of the packaging 4 from. The items packed in the packaging are then freely available for sale by placing them in the lower part of the packaging 2 remain, thus forming a tray-shaped packaging part.

Like the connection between the two packaging parts 2 . 4 solved and the upper packaging part 4 from the lower part of the packaging 2 is separated is schematically in the 3 and 4 shown. For this purpose, one engages from the outside by means of at least one finger through the finger or handle hole 40 through and out, viewed from the outside, grasps below the handle hole 40 lying attachment section 34 , This will affect the inside of the attachment section 34 Pressure exerted in the outward direction. In this way you pull with the help of the attachment section 34 the associated long side wall portion 20 of the upper packaging part 4 and the externally applied long side wall portion 6 of the lower packaging part 2 outward. This drawing process continues until along the two perforation lines 36 about which the attachment section 34 with the remaining part of the associated long side wall section 20 of the upper packaging part 4 connected, a crack is formed and thereby the attachment portion 34 from the remaining part of the long side wall section 20 is disconnected. Since the attachment section 34 with the help of the splices 38 . 42 on the inside of the long side wall section 6 of the lower packaging part 2 is permanently attached, there remains the attachment portion 34 , In contrast, arises in the long side wall section 20 of the upper packaging part 4 a corresponding recess 44 after lifting the upper part of the packaging 4 from the lower part of the packaging 2 or when separating the two packaging parts 2 . 4 visible from each other, like 4 lets recognize.

Since, as stated previously, the attachment portion 34 in the illustrated embodiment is dimensioned such that this over the upper free edge 6a of the long side wall section 6 of the lower packaging part 2 does not stick out, but at best with its upper free edge 34b at the height of the upper free edge 6a of the long side wall section 6 is the attachment section 34 Not visible from the outside, although it by the bond to the inside of the long side wall section 6 of the lower packaging part 2 remains. This results in the presentation to advantages both in terms of visual appearance and in terms of handling.

After completion of the previously based on the 3 and 4 described separation process returns the side wall portion 6 of the lower packaging part 2 back to its original position, in which it lies essentially in one plane. This results from a certain elasticity inherent in at least the entire assembly. Thus, the original shape (in the illustrated embodiment, a cuboid shape) of the now serving as a tray lower packaging part remains 2 receive.

The separation process described above is in the illustrated embodiment usually simultaneously on both mounting portions 34 carried out.

Finally, it should be noted that the number of fastening sections to be used 34 be arbitrary and, for example, at least one further attachment portion 34 in the area of the narrow side wall sections 22 of the upper packaging part 4 can be provided. Just if also the attachment sections 34 be formed in a different shape than the trapezoidal shape shown in the figures and, for example, have a rectangular, rectangular or circular shape. Also, the attachment sections must 34 not necessarily to the fold line 16 of the lower packaging part 2 extend, which in the folded state, the lower edge of the long side wall sections 6 and narrow side wall sections 8th and thus the bottom edge of the lower packaging part 2 forms, but can for example also above this fold line 16 end up.

After all It should also be noted that the blanks for the two packaging parts can also be designed that the two-piece package in the erected state another Form as the previously mentioned cuboid shape receives. For example, the cross section may also be square or the entire packaging have a cube shape. It is also conceivable that the packaging in cross-section a triangular or even polygonal shape has.
