Description

The invention relates to a base made of a foldable material, such as cardboard, corrugated board or cardboard, with side walls, a contact surface formed by bottom tabs for placement on a substrate and a contact surface facing away from the contact surface formed by cover tabs. The side walls can be erected from an at least partially flat superimposed transport state into a use state in which they form an annular hollow edge, which is defined by spaced from each other via the bottom and cover flaps inner and outer side walls. Furthermore, the invention relates to a blank for producing such a base.

For the presentation and the sale of goods from goods carriers, it is known to arrange this handle height and thus easily visible for a consumer and easily accessible. For this purpose, goods carriers, such as spouts, trays or the like., Arranged on a pedestal. In the same way, displays can also be positioned on such pedestals in a visually easily perceivable height. Such a pedestal may be placed directly on a floor or the like or formed as a so-called pallet base for connection to a pallet. For example, pallet sockets are connected to a plastic ¼ Chep pallet, which in turn is placed on the floor.

In order to accommodate the weight load of product-filled goods carrier and / or a display, such sockets usually consist of a compartment of several reinforced webs and a longitudinally glued shell, for example, which in addition to the absorption of forces and the panel the base is used. The truss-forming webs are separate components from the shell of the socket, so that the costs and the logistics outlay for providing such a socket are comparatively high. In addition, the manageability of a multi-element socket, which must be erectable in a shop, a branded goods or a co-packer in the shortest possible time by often unskilled assistants, perceived as in need of improvement.

Next, sockets are known which are similar in structure to a packaging box with automatic bottom. Such a pedestal is from the EP 0 850 843 A2 known. The automatic floor closes automatically when erecting the base. Although these pedestals have a lower assembly cost compared to multi-part base constructions, they generally only have low wearing properties, so that they can not be used for certain applications.

From the DE 20 2004 202 707 U1 as well as the 10 2004 003 246 B4 are a base and a blank of the type mentioned above, in which the hollow edge ensures high stability of the base. For the construction of the base from the flat lying transport state in the erected condition of use, first floor flaps are folded and locked and then pivoted the inner side walls on the cover flaps inward.

Object of the present invention is in contrast to provide a base of the type mentioned, which is easier to install with improved handling and unskilled assistants and at the same time has a high load capacity. Next, a blank for such a socket is to be provided.

This object is achieved essentially with a base according to claim 1 and a blank according to claim 9.

In this case, the invention provides that the inner side walls are hinged together via hinged swivel plates. This causes the inner sidewalls to move together. It is possible in this way, by pivoting a single inner side wall at the same time to pivot the other inner side walls with. The labor required to erect the base from the flat transport state to the use state is thereby considerably reduced, because instead of four steps (in a rectangular base with four side walls) only a single step is required. At the same time, in particular, the high stability of the DE 10 2004 003 246 B4 known socket and its good handling are maintained, which can be dispensed with in contrast to other known sockets on a Gefache.

According to a preferred embodiment of the invention, the cover flaps of the base are designed such that they can form an at least substantially closed hinged lid. This makes it possible to place on the upper side of the base in the state of use, packaging, or even individual products. The hinged lid does not have to form a completely closed surface, but it is possible that, for example, stacking openings and / or openings for actuating the cover tabs are provided in the hinged lid.

In a further development of this inventive concept, preferably at least two of the cover tabs are substantially rectangular and extend, for example, over half of the depth of the base. In other words, the extension of the cover tabs in the direction of the outer side wall to which they are hinged, to its free end is slightly equal to half of Width of a respective adjacent outer side wall. Even if, for reasons of material usage, such a configuration is preferred, other subdivisions of the cover tabs can also be represented, for example, a cover tab substantially extending over the entire cover surface.

The erection of the socket according to the invention can be further facilitated by the fact that the inner side walls automatically pivot relative to the outer side walls when the cover tabs are folded down. In combination with the connection of the inner side walls to one another via the pivoting lugs, this causes the complete hollow edge to be erectable by pivoting a single cover lug.

This can be achieved, for example, in that on each inner side wall on the side facing away from the respective bottom flap via an initial creasing or bending line, an adhesive flap is hinged, which is connected to the respective cover flap, that the first crease line or bend parallel offset is arranged to a second creasing or bending line, with which the respective lid flap is hinged to the respective outer side wall. The offset of the creasing or bending lines of the cover flap and the adhesive flap thereby causes the inner side wall to be pushed inwards and downwards when the cover flap pivots. The offset of the creasing or bending lines is designed such that the first creasing or bending line, with which the adhesive flap is articulated on the inner side wall, closer to the free end of the cover flap than the second crease line or bend.

In the transport state of the base, the adhesive tabs are preferably already connected to the lid flaps and the inner side walls are each between an outer side wall and another inner side wall. In other words, first, the inner sidewalls on the outer Folded side walls, so that in a rectangular packaging, the four superposed side wall pairs are arranged side by side. Subsequently, for example, the two outer side wall pairs are unfolded on the two inner side wall pairs and connected to an adhesive flap, so that the superposed side wall pairs form a closed shell.

The transport state is a state in which the base is pre-assembled to the extent that the necessary bonds or other connections of the tabs has already taken place among themselves, the base is still in a flat state, in which a space-saving shipping or storage of Socket is possible before use. The actual erection of the base in its transport state can then be comparatively quickly and easily done as described above by the side walls are first unfolded from the flat state in a rectangular shell and then the cover tabs are closed, whereby also the inner side walls relative to the outer Move side walls so that the hollow edge forms.

If the swivel plates are articulated on the inner side walls such that the swivel plates protrude in the direction of the bottom flaps and in the direction of the cover flaps by approximately one material thickness each, the swivel flaps can absorb vertical loads. There are lid tabs on the swivel tabs and the swivel tabs are located on the opposite side in a plane with the bottom flaps. The carrying capacity of the base according to the invention can thereby be further improved.

Stacking protrusions and / or stacking corners may be provided on the outer sidewalls to facilitate connection to other packages to be received by the socket. When several pedestals stacked on top of each other are to be provided, stacking openings for receiving the stacking projections or stacking corners in the base. Preferably, the stacking projections or stacking corners are formed so that they point to the outer side walls in the transport state in the direction of the cover tabs. In other words, the stacking projections and / or stacking corners lie substantially within the cover tabs, but are separated therefrom by an incision. This causes the stack projections to project upwardly over the plane of the lid when the lid tabs are folded over.

Additionally or alternatively, connector tabs may be provided in the bottom flaps and / or in the outer sidewalls. These may be, for example, about T-shaped tabs, which are bounded by a perforated line. The connector tabs can thus be broken out of the bottom flaps or outboard sidewalls when needed and can be used for connection to members located below the pedestal. In this way, the base can for example be fixed on a pallet or stacked pedestals can be connected to each other. Further, corresponding openings or the like may be provided on the opposite side of the socket to receive such connector tabs.

The base according to the invention does not have to be used in such a way that the cover flaps lie vertically upwards in the state of use and the bottom flaps lie vertically downwards in the state of use. Rather, it is also possible to use the base turned by 180 ° if necessary, if a closed bottom is preferred.

An inventive blank for the production of such a base consists of a foldable material, such as cardboard, corrugated cardboard or cardboard. Of the Blank has over Rill- or bending lines hinged together outer side walls and hinged to these bottom flaps and lid flaps, which are hinged to the bottom flaps inner side walls whose height is substantially equal to the outer side walls and whose width is less than that of the outer side walls. The bottom flaps can be configured at least approximately trapezoidal. According to the invention, the inner side walls are hinged to each other via hinged flaps. Alternatively or additionally, adhesive tabs are preferably articulated on the side facing away from the bottom flaps of the inner side walls via creasing or bending lines.

In principle, it is possible to form the blank for the production of the base as a one-piece blank. However, due to the size of the base and / or because of the processability in printing machines, for example in offset printing instead of in flexographic printing, a two-part blank can also be used. In a two-part blank each two outer side walls are hinged directly to each other and two inner side walls connected via two pivoting plates. Further, for example, on an outer side wall and an inner side wall adhesive tabs are provided for connection to a structurally identical blank. Even with a one-piece blank adhesive tabs are provided, for example, on an inner side wall and an outer side wall, so that the side walls can be joined together to form a closed shell.

The invention will be explained in more detail by means of embodiments and with reference to the accompanying drawings.

The in Fig. 1 shown one-piece blank has four outer side walls 1, 2, 3, 4, which are each hinged to each other via creasing or bending lines, and four inner side walls 5, 6, 7, 8. The height of the outer sidewalls and the inner sidewalls is at least substantially equal, with the inner sidewalls being narrower than the outer sidewalls, as shown. The inner side walls 5, 6, 7, 8 are hinged to the outer side walls 1, 2, 3, 4 via slightly trapezoidal bottom flaps 9.

Between the inner side walls 5, 6, 7, 8 two swivel plates 10 are provided in each case, which are articulated via creasing or bending lines on the respective inner side walls and are interconnected in the illustrated embodiment via two webs.

On the bottom flaps 9 side facing away from the inner side walls adhesive tabs 11, 12 are articulated in each case via a creasing or bending line 13. The adhesive tabs 11 are substantially rectangular, while the adhesive tabs 12 are formed approximately trapezoidal. In principle, however, the adhesive tabs can also have another suitable shape.

On the bottom tabs 9 side facing away from the outer side walls 1, 2, 3, 4 14 each cover tabs 15, 16 is articulated via a crease or bending line. In this case, the lid tabs 15, which are hinged to the wider side walls 1 and 3, in turn, an approximately rectangular shape, while the cover plates 16, which are hinged to the narrower side walls 2, 4, have an approximately trapezoidal shape. Further, at the free edge of the outer side wall 4 and the inner side wall 5 each adhesive tabs 17 are provided, with which the outer side wall 4 with the outer side wall 1 and the inner side wall 5 with the inner side wall 8 associated pivoting lug 10 can be connected.

How out Fig. 1 it can be seen, the creasing or bending line 14, with which the cover tabs 15, 16 are hinged to the respective outer side walls, not continuous, but is interrupted by stacking projections 18 and stacking corners 19. The stacking projections 18 and the stacking corners 19 extend in the in Fig. 1 shown state of the blank into the respective cover tabs 15, 16 in, but are separated from them by cuts.

Further, 9 connectors 20 are formed in the bottom flaps, which are connected by a perforated line with the bottom flaps 9, but can be broken out of these. Around the connector tabs 20 around a also extending into the respective inner side walls 5, 6, 7, 8 extending recess. The connector tabs 20 are used, for example, the locking of the base on a pallet.

In comparison with the dimensions of the side walls of the blank after Fig. 1 is the cut to Fig. 2 designed so that it can be used for example for a ¼ Chep range, whereas the cut to Fig. 1 is suitable for only half the size of a pedestal, ie, two such pedestals can be arranged on a ¼ Chep pallet. In Fig. 2 only one blank of two identical blanks is shown, which are required together for the manufacture of a base according to the invention. Same parts are given the same reference numerals as in Fig. 1 designated.

Notwithstanding the embodiment in Fig. 1 the connector tabs 20 are formed substantially T-shaped. In addition, recesses are provided in the outer side walls, in which the connector tabs of an overlying base can be introduced, as in Fig. 5 is shown. In addition, the stack projections 18 and stack corners 19 are provided corresponding areas along the bottom flaps 9 with the outer side walls connecting creases or bending lines, which are realized breakable in the illustrated embodiment by a perforation.

The preparation of a base according to the invention from two blanks Fig. 2 is in the Fig. 3a to 3d shown. Fig. 3a already shows the state in which the two blanks on the adhesive tabs 17 are connected to each other so that the two blanks lie side by side. In this position, an adhesive is applied to the adhesive tabs 11 and 12 or on the cover tabs 15 and 16 or activated an existing adhesive, so that in the subsequent unfolding in the in Fig. 3b shown position the adhesive tabs 11, 12 with the cover tabs 15, 16 are firmly connected. Folding into position after Fig. 3b takes place along the creasing or bending line, via which the outer side walls are hinged to the bottom flaps 9. Therefore, the inner side walls are relative to the outer side walls offset by the height of the bottom flaps 9, whereby the adhesive flaps 11, 12 are substantially flush with the lid flaps 15, 16. The creasing or bending line 13 is therefore also offset by the height of the bottom flap 9 to the creasing or bending line 14.

From the in Fig. 3b As shown, the blank can be moved to the position Fig. 3c be converted by the respective outer side wall pairs are folded onto the respective inner side wall pairs. Thus, the inner side walls lie on each other. In this state, the in Fig. 3b each outer side walls are glued together, so that a flat-lying shell as shown in FIG Fig. 3d arises. In this flat transport mode, the base can be stored and shipped to save space.

To build the base from the transport state into the state of use, the side wall pairs are first pulled apart so that forms a rectangular shell, in which the inner side walls, however, still rest on the outer side walls. This is in Fig. 4a shown. In this condition, the connector tabs 20 may be used to connect the pedestal to a pallet 21. This is in Fig. 4b indicated by the arrows. Subsequently, the hollow edge of the base can be set up by one of the two cover tabs 15 and 90 ° is pivoted. Due to the connection of the inner side wall 5 via the adhesive flap 11, the inner side wall 5 is here pivoted inwardly and downwardly. Since the inner side walls are hinged to each other via the pivot plates 10, all inner side walls are pivoted at the same time, so that the entire hollow edge rears up by folding a single lid flap. In this case, the other lid flaps, as in the Fig. 4b and 4c indicated.

Fig. 5 shows the use of two as in the Fig. 3a to 4c upright pedestal on a pallet 21, with two pedestals stacked on top of each other. It can be seen how the stacking projections 18 and stacking corners 19 engage in corresponding recesses of the overlying base. Further, the connector tabs of the upper socket engage in the corresponding recesses of the lower base.
