Definitions

• the invention relates to a box made from a cardboard box, which can be folded flat in the fully glued state, with a space division by inner walls, which are folded up from the inward in the collapsed state against the chess side walls and attached to the latter along the bending lines four bottom parts 'The flaps are formed, of which two neighboring ones are glued to each other and automatically take up their position as upright inner walls when the flat folded folding box is erected into the room shape.
• folding boxes of this type have a plurality of compartments separated from one another by the inner walls for receiving sensitive products in each of the compartments, in which they are mutually protected by the inner walls.
• Folding boxes of this type can be designed in such a way that they already contain the bottom, side walls and all inner walls connected to one another in the flat folded state in such a way that the box straightens up from the flat state by exerting pressure from opposite sides into the spatial shape lets, where then all inner walls automatically take their position as partitions.
• the folding box consists of a one-piece blank, of which individual parts are glued together, 6264
• the flat shape can be created with one hand from the flat folded state.
• the advantage of such folding boxes is in particular that the prefabricated folding boxes can be stacked in a very space-saving manner before use for the purpose of packaging products in the folded state.
• the object underlying the present invention was to improve folding boxes of this type in order to be able to pack products which are particularly sensitive to impact.
• the products should be softly supported in order to withstand vibrations occurring during transport.
• the folding box has the features of claim 1.
• the resilient box oden has the advantage that shocks during transport do not have a negative effect on the contents of the box and that even in stacked, filled folding boxes there is a free space underneath each box oden and therefore there is no direct contact between the cardboard layers enclosing the contents of the box . So that the inwardly arched box bottom does not push itself flat under heavy loads, additional support feet are provided that maintain a minimum degree of arching.
• 1 shows the blank for a first embodiment of the folding box with four compartments formed by inner walls; 2 shows the folding box folded flat after gluing together before erection;
• Fig. 4 is a plan view of the underside of the folding box
• FIG. 5 shows the blank for a further embodiment of a folding box with six compartments separated by inner walls
• FIG. 6 shows the folding box manufactured using the blank according to FIG. 5 after gluing in the flat folded state
• FIG. 8 is a plan view of the bottom surface of the folding box according to FIG. 7.
• the first embodiment of the folding box is produced from a one-piece cardboard blank 1 shown in FIG. 1.
• the blank 1 comprises four box side walls 4, 5, 6 and 7 and bottom parts 8, 9, 10 and 11 attached to each of them along a bending line.
• the adhesive flap 13 attached to the side wall 7 is fixed to the free end of the side walls 4 sticks.
• Flaps 14, 15, 16 and 17 are attached to the bottom parts 8, 9, 10 and 11 along bending lines.
• the non-continuous bend line ends in an arcuate and then an oblique line • P 64
• the area 21 marked with crosses is connected from the bottom part 11 to the bottom part 10 by gluing in the area 22 marked with crosses.
• the adhesive flap 23 attached to the flap 17 along a bending line is connected to the flap 16 in the adhesive area marked with triangles.
• the blank 1 according to FIG. 1 is designed in such a way that the length a of the base part 8 measured between the two bending lines and the length b of the base part 10 measured between the two bending lines together are somewhat greater than the length c of the side wall 5 parallel to this when the folding box is erected also for the bottom parts 9 and 11 and the side wall 6 too.
• the individual base parts are inclined from the bending line to the adjacent box side wall starting towards the middle of the box and resiliently yielding, and so that this inclination is maintained even under load
• the flap attached to the end of the upstanding bottom part and functioning as a partition wall each has a support foot in the form of the edge projection 14a or 15a or 16a or 17a, which support feet are each Support on the inside of the floor part adjacent to the flap:
• the type of support is shown in FIG. 3.
• the folding box has four separate compartments due to the four flaps 14-17 which are connected in pairs. The front right corner of the box is cut away in order to show the function of the support leg obtained by reducing the base part.
• the bottom of the box shown in FIG. 4 reveals that the two perforation lines 2 and 3 in the base parts 9 and 11 lie on a line connecting two corners, which move in the opposite direction when the box is pressed against one another by the two other corners to be brought into the flat folded state according to FIG. 2.
• FIGS. 5-8 the same principle is used to produce an inwardly curved and resilient box bottom by the small excess length of the bottom parts and mutual support thereof.
• FIG. 5 for the production of the folding box, corresponding parts are designated with the same reference numerals as in the first exemplary embodiment.
• the folding box has four side walls 4, 5, 6 and 7 and base parts 8, 9, 10 and 11 attached to these along longitudinal bending lines.
• 64 64
• a flap 25 attached to the following base part 9 along a bending line has, adjacent to the bending line, a flap base 29 of the same length and a flap part 30 projecting asymmetrically to one side.
• the flap 25 has an adhesive tab 31 which is freely attached along a bending line and is marked with triangles and which is glued to the flap 24 in the area 32 marked with triangles.
• an edge projection 33 for the flap 25 is formed on the bending line between the flap 25 and the bottom part 9 by reducing the bottom part 9 on the middle of the bending line by means of a cut 32, which edge projection forms a supporting foot in the center of the bottom when the folding box is erected.
• the flap 26 also has a slot 28 in the middle, next to which in the area 32 the adhesive flap attached to the flap 27 along a bending line
• the asymmetrical flap 27 also has a Kl appe ⁇ sockel 29 and a flap part 30 projecting opposite to this on one side and an edge projection 33 formed on the bending line by a cut 32 as a supporting foot.
• a corner C is formed at the covering area of the two base parts 8 and 9, the base part 9 coming to rest on the base part 8 and these are bonded to one another in the zones 18 and 19. This corner lies with the erected folding box on the longitudinal center line through the floor.
• the inwardly curved box bottom in turn arises from the slight excess length of the bottom parts, the longitudinal axis of the folding box being identical in this case with respect to the longitudinal axis of the folding box which is identical to the above-mentioned center line, that the length a of the bottom part 8 measured between the associated bending lines and the corresponding length b des Bottom part 10 and the length s of the flap base 29 of the flap 25 or 27 added together are somewhat larger than the length c of the side wall 5 parallel to it.
• the box base which is thereby angled inwards at an angle, therefore has resilient bottom parts le inclined towards the center .and so that this inclined position is maintained even when the bottom of an overall non-rigid box is loaded, the edge projections 33 provided on the flaps 25 and 27 are located in the center of the bottom as support feet on the base or, in the case of stacked folding boxes, on the box lid of the lower one in each case Box on.
