Description

Description [0001] The invention relates to a base made of a foldable material, such as cardboard, corrugated cardboard or paperboard, having side walls, a contact area formed by base flaps for positioning on a ground and a receiving area formed by cover flaps, facing away from the contact area. The side walls can be erected from a transport state lying flat upon one another at least in some regions to a use state, in which they form an annular hollow edge defined by the inner and outer side walls, which are spaced apart from one another by means of the base and cover flaps. The invention also relates to a blank for manufacturing such a base.

[0002] For displaying and selling goods from product holders, it is known to place these at grab height and therefore easy to see and access by a consumer. For this purpose product holders, such as for example containers, trays or the like, are arranged on a base. In the same way displays can also be positioned at an optically good perceptible height on such bases. Such a base can be erected directly on a floor or the like or can be designed as a so-called pallet base for connection to a pallet. Pallet bases for example are connected to a plastic Chep quarter pallet, which in turn is placed on the floor.

[0003] In order to withstand the weight of the product holders loaded with products and/or of a display, such bases usually consist of a partition of several reinforced webs and a sleeve for example bonded in the longitudinal direction which, apart from resisting forces, also serves to line the base. The webs forming the partition are structural elements separate from the sleeve of the base, meaning that the costs and logistical effort for supplying such a base are relatively high. In addition the manageability of a base, which must be able to be erected in a shop, at a proprietary brand manufacturer or contract packer in the shortest possible time by frequently unskilled temporary workers and which consists of several components, is felt to merit improvement.

[0004] Furthermore bases, which are similar in structure to a packaging case with automatic base, are well-known. Such a base is disclosed in EP 0 850 843 A2. The automatic base locks automatically when the base is erected. Compared to multipart base designs these bases are less complex to assemble but usually only possess minimum weight-bearing properties, meaning that they are not practical for certain applications.

[0005] DE 20 2004 202 707 Ul, as well as DE 10 2004 003 246 B4, discloses a base and a blank of the type detailed above, wherein the hollow edge provides high stability for the base. For erecting the base from the flat-lying transport state to the use state, firstly base flaps are turned down and locked and then the inner side walls are pivoted inwards over the cover flaps.

[0006] In contrast to this the object of the present invention is to create a base of the type detailed above, which can be erected faster and has improved manageability even by unskilled temporary workers and at the same time possesses a high weight-bearing capacity. A blank should also be created for such a base.

[0007] This object is substantially achieved with a base according to claim 1 and a blank according to claim 9.

[0008] Here it is proposed according to the invention that the inner side walls are connected with one another by means of articulated pivoting flaps. This has the effect that the inner side walls can move in unison. In this way it is also possible to pivot the remaining inner side walls simultaneously by pivoting only one inner side wall. The effort for erecting the base from the flat-lying transport state to the use state is substantially reduced because only one operation is necessary instead of four operations (in the case of a rectangular base having four side walls). At the same time in particular the high stability of the base known from DE 10 2004 003 246 B4 and its good manageability can be maintained, as the result of which, in contrast to other well-known bases, a partition can be dispensed with.

[0009] According to a preferred embodiment of the invention the cover flaps of the base are configured in such a manner that these can form an at least generally closed hinged cover. It is possible thereby to place containers, packagings or even individual products on the side of the base uppermost in the use state. The hinged cover thereby does not have to form a completely closed face, but it is possible that e.g. stacking openings and/or openings for manipulating the cover flaps are provided in the hinged cover.

[0010] In a further embodiment of this inventive concept, preferably at least two of the cover flaps are substantially rectangular and for example extend in each case over half the depth of the base. In other words the extension of the cover flaps in the direction away from the outer side wall, on which they are articulated, towards their free end roughly corresponds to half the width of a respectfully adjacent outer side wall. Even if such an arrangement is preferred for reasons of material thickness, different divisions of the cover flaps are also feasible, for example a cover flap substantially extending over the entire cover face.

[0011] Erecting the inventive base can be further facilitated by automatically pivoting the inner side walls relative to the outer side walls, whenever the cover flaps are turned down. In combination with the connection of the inner side walls with one another by means of the pivoting flaps, this has the effect that the complete hollow edge can be formed by pivoting a single cover flap.

[0012] For example this can be achieved by an adhesive flap being articulated to each inner side wall on the side facing away from the respective base flap by means of a first groove or bending line, which adhesive flap is connected to the respective cover flap in such a manner that the first groove or bending line is disposed parallel offset with respect to a second groove or bending line, with which the respective cover flap is articulated on the respective outer side wall. The offset of the groove or bending lines of the cover flap and the adhesive flap has the effect that, when the cover flap is pivoted, the inner side wall is pushed inwards and downwards. The offset of the groove or bending lines in this case is such that the first groove or bending line, with which the adhesive flap is articulated on the inner side wall, lies nearer to the free end of the cover flap than the second groove or bending line.

[0013] In the transport state of the base, the adhesive flaps are preferably already connected to the cover flaps and the inner side walls each lie between an outer side wall and another inner side wall. In other words firstly the inner side walls are unfolded onto the outer side walls, so that in the case of a rectangular packaging the four side wall pairs lying upon one another are disposed next to each other. Subsequently, for example, the two outer pairs of side walls are unfolded onto the two inner side wall pairs and connected to an adhesive flap, so that the side wall pairs lying upon one another form a closed sleeve.

[0014] The transport state is thereby a state, in which the base is prefabricated so far that the necessary bonding or other interconnections of the flaps have already taken place, the base however still being in a flat-lying state, in which the base can be conveyed and stored before use in a space-saving manner. Actual erection of the base to its transport state can then take place comparatively rapidly and simply as described above, by firstly the side walls being unfolded from the flat-lying state into a rectangular sleeve and then the cover flaps being locked, as a result of which the inner side walls are also moved relative to the outer side walls in such a manner that the hollow edge is formed.

[0015] Whenever the pivoting flaps are articulated on the inner side walls in such a manner that the pivoting flaps each project by roughly a material thickness in the direction of the base flaps and in the direction of the cover flaps, the pivoting flaps can withstand vertical loads. In this case cover flaps lie upon the pivoting flaps and the pivoting flaps are located on the opposite side level with the base flaps. The weightbearing capacity of the inventive base can be further improved hereby.

[0016] Stacking projections and/or stacking comers can be provided on the outer side walls, in order to facilitate connection with other packagings to be held by the base. Whenever several bases are to be stacked on top of one another, stacking openings can also be provided in the base for receiving the stacking projections and/or stacking corners. Preferably the stacking projections and/or stacking corners are designed in such a manner that these on the outer side walls in the transport state point in the direction of the cover flaps. In other words the stacking projections and/or stacking corners generally lie within the cover flaps, but are separated from these by means of an incision. This has the effect that the stacking projections and/or stacking corners protrude upwards over the level of the cover when the cover flaps are turned down.

[0017] Additionally or alternatively to this connector flaps may be provided in the base flaps and/or in the outer side walls. For example these can be roughly T-shaped flaps which are circumscribed by a perforated line. The connector flaps can therefore be pried out of the base flaps and/or out of the outer side walls as required and can be used to connect to elements lying under the base. In this way the base can be fixed for example to a pallet or bases stacked on top of one another can be connected with each other. Corresponding openings or the like can also be provided on the opposite side of the base in order to receive such connector flaps.

[0018] The inventive base does not have to be used so that the cover flaps lie vertically upwards in the use state and the base flaps lie vertically downwards in the use state. In fact it is also possible to use the base folded by 180° as required if a closed base is preferred.

[0019] An inventive blank for manufacturing such a base consists of a foldable material, such as cardboard, corrugated cardboard or pasteboard. The blank has outer side walls articulated to one another by means of groove or bending lines and base flaps and cover flaps articulated to these, wherein inner side walls, the height of which generally corresponds to that of the outer side walls and the width of which is less than that of the outer side walls, are articulated to the base flaps. The base flaps can be at least roughly trapezoidal. According to the invention the inner side walls are connected with each other by pivoting flaps articulated to one another. Alternatively or additionally to this on the side of the inner side walls, facing away from the base flaps, adhesive flaps are preferably articulated by means of groove or bending lines.

[0020] In principle it is possible to design the blank to manufacture the base as a one-piece blank. However depending on the size of the base and/or processability in printing presses, e.g for offset printing as opposed to flexographic printing, a two-piece blank can also be used. With a two-piece blank in each case two outer side walls are directly articulated to one another and two inner side walls are connected with each other by two pivoting flaps. Furthermore for example adhesive flaps are provided for connection to an identically designed blank on an outer side wall and an inner side wall. Also in the case of a one-piece blank e.g. adhesive flaps are provided on an inner side wall and an outer side wall, so that the side walls can be connected with each other to form a closed sleeve.

[0021] The invention is described below in detail on the basis of exemplary embodiments and with reference to the appended drawing.

[0022] This shows schematically:

Fig. 2 a part of a two-piece blank for a base according to a second embodiment of the invention,

Figs. 3a to 3d in schematic perspective view the folding- and adhesive sequence for the blank according to Fig. 2 into a base in its transport state,

Figs. 4a to 4c in schematic perspective view the steps of erecting the base according to Fig. 2 from its transport state to the use state and

Fig. 5 in perspective view two bases stacked on top of one another.

[0023] The one-piece blank shown in Fig. 1 has four outer side walls 1, 2, 3, 4, which are each articulated to one another by means of groove or bending lines, and four inner side walls 5, 6, 7, 8. The height of the outer side walls and the inner side walls is at least generally identical, the inner side walls as illustrated being narrower than the outer side walls. The inner side walls 5, 6, 7, 8 are articulated on the outer side walls 1, 2, 3, 4 by means of roughly trapezoidal base flaps 9.

[0024] In each case two pivoting flaps 10, which are articulated on the respective inner side walls by means of groove or bending lines and in the embodiment illustrated are connected with each other by two webs, are provided between the inner side walls 5, 6, 7, 8.

[0025] On the side facing away from the base flaps 9 of the inner side walls, adhesive flaps 11,12 are each articulated by means of a groove or a bending line 13. The adhesive flaps 11 in this case have a substantially rectangular shape while the adhesive flaps 12 have a roughly trapezoidal shape. In principle however the adhesive flaps can also have another suitable shape.

[0026] On the side facing away from the base flaps 9 of the outer side walls 1, 2, 3, 4, cover flaps 15, 16 are each articulated by means of a groove or a bending line 14. In this case the cover flaps 15, which are articulated on the wider side walls 1 and/or 3, again have a rectangular shape, while the cover flaps 16, which are articulated on the narrower side walls 2, 4, have a trapezoidal shape. Furthermore adhesive flaps 17, with which the outer side wall 4 can be connected to the outer side wall 1 and the inner side wall 5 to the pivoting flap 10 associated with the inner side wall 8, are provided at the free edge of the outer side wall 4 and the inner side wall 5 in each case, [0027] As evident from Fig. 1, the groove or bending line 14, with which the cover flaps 15, 16 are articulated on the respective outer side walls, does not run continuously but is interrupted by stacking projections 18 and/or stacking corners 19. The stacking projections 18 and the stacking corners 19 in the state shown in Fig. 1 of the blank reach into the respective cover flaps 15, 16, but are separated from these by incisions.

[0028] Furthermore connectors 20, which are connected to the base flaps 9 by a perforated line, are formed in the base flaps 9 but can be pried out from these. A recess also reaching into the respective inner side walls 5, 6, 7, 8 extends around the connector flaps 20. The connector flaps 20 for example serve to lock the base onto a pallet.

[0029] In comparison with the dimensions of the side walls of the blank according to Fig. 1, the blank according to Fig. 2 is designed in such a manner that this can be used e.g. for a Chep quarter pallet, whereas the blank according to Fig. 1 is only suitable for half as large a base, i.e. two such bases can be placed on a Chep quarter pallet. Only one of two identical blanks is illustrated in Fig. 2, which are together necessary to manufacture an inventive base. Similar parts are designated with the same reference symbols as in Fig. 1.

[0030] Deviating from the embodiment in Fig. 1 the connector flaps 20 are generally T-shaped. Recesses are also provided in the outer side walls, into which the connector flaps of a base lying above can be engaged, as illustrated in Fig. 5. Regions corresponding to the stacking projections 18 and stacking comers 19, which are realized in the embodiment illustrated so they can be pried out by way of a perforation, are also provided along the groove or bending lines connecting the base flaps 9 to the outer side walls.

[0031] The manufacture of an inventive base from two blanks according to Fig. 2 is illustrated in Figs. 3a to 3d. In this case Fig. 3a already shows the state, in which the two blanks are connected with each other by the adhesive flaps 17, so that the two blanks lie next to one another. In this position an adhesive is applied to the adhesive flaps 11 and 12 and/or to the cover flaps 15 and 16 or an existing adhesive is activated so that, during subsequent unfolding into the position shown in Fig. 3b, the adhesive flaps 11,12 are firmly connected to the cover flaps 15, 16. Unfolding into the position according to Fig. 3b is thereby effected along the groove or bending line, by means of which the outer side walls are articulated to the base flaps 9. Therefore the inner side walls are disposed offset relative to the outer side walls by the height of the base flaps 9, as a result of which the adhesive flaps 11,12 terminate substantially flush with the cover flaps 15, 16. The groove or bending line 13 is thus likewise offset to the groove or bending line 14 by the height of the base flap 9.

[0032] The blank can be transferred from the position shown in Fig. 3b into the position according to Fig. 3c, by unfolding the respective outer side wall pairs onto the respective inner side wall pairs. Thus the inner side walls lie upon one another. In this state the respective outer side walls in Fig. 3b can be bonded together, so that a flat-lying sleeve in accordance with the illustration in Fig. 3d is formed. In this flat-lying transport state the base can be stored and conveyed in a space-saving manner.

[0033] For erecting the base from the transport state to the use state, the side wall pairs are firstly pulled apart so that a rectangular sleeve, in which the inner side walls however still lie upon the outer side walls, is formed. This is illustrated in Fig. 4a. In this state the connector flaps 20 can be used to connect the base with a pallet 21. This is suggested in Fig. 4b by the arrows. The hollow edge of the base can be subsequently formed, by pivoting one of the two cover flaps 15 by 90°. Due to the inner side wall 5 being connected by means of the adhesive flap 11, the inner side wall 5 is pivoted inwards and downwards in this case. Since the inner side walls are together articulated to one another by means of the pivoting flaps 10, all inner side walls are pivoted accordingly at the same time, so that the entire hollow edge is formed by turning only one cover flap down. In this case the remaining cover flaps also lock, as suggested in Figs. 4b and 4c.

[0034] Fig. 5 shows the use of two bases erected on a pallet 21 as in Figs. 3a to 4c, the two bases being stacked on top of one another. Here it is evident how the stacking projections 18 and stacking corners 19 engage into corresponding recesses of the base lying above. The connector flaps of the upper base also engage into the corresponding recesses of the lower base.
