Definitions

• the invention relates to a container, in particular a folding box or folding shaft made of corrugated cardboard for the transport of heavier objects, in particular moving carton / the bottom of which is formed by folding together v extension parts of the two large side walls and the two small side walls designed with grip holes.
• this area is able to absorb and redirect greater forces.
• the invention is based on the finding that this is the weak point in known folding cartons.
• By the Invention 'type configuration of the strength comparable cartons can be increased by a multiple.
• Experiments had shown that a folding box according to the invention can have a tear strength of over 2000 N.
• the cutouts are formed with a web arranged in the center at a certain distance from the ends of the extension part, and the outer parts of the extension parts of the large side walls are formed with centrally arranged cutouts to their lateral boundaries.
• the extension of the small side walls in the area between the base of the cutout and the adjacent folded edge is provided with a reinforcing part.
• the material for the folding carton according to the invention is corrugated and solid cardboard, corresponding plastics or material combinations.
• Fig. 1 shows a diagrammatic view of a container according to the invention.
• Fig. 2 shows, on an enlarged scale, a detail in the area of the grip hole of a container according to the present invention.
• Fig. 3 shows the area of a finger hole on an enlarged scale.
• Fig. 4 shows a bottom view of a folding box according to the invention.
• Fig. 5 shows details in the area of the lid of a carton according to the invention.
• 10 denotes a container according to the invention, specifically a corrugated cardboard box, which can also be used for moving books, for example, when moving house.
• the container is formed in the usual way from a cardboard blank by folding.
• the container has a handle hole 11 on its small side walls, namely the end wall parts.
• the end wall part is delimited by a fold line 12, as is customary in corrugated cardboard boxes.
• the side wall part is extended beyond the fold line 12 and has two parts 13 and 16 of essentially the same size, which are separated from one another by a fold line 14.
• a tab part 17 In the middle area of the extension part, namely in the area of the fold line 14, there is a tab part 17. This is formed by pre-punching on three boundary lines, because the fourth boundary line only represents one fold line 18.
• Fig. 2 shows how the side part 16 is placed by 180 ° around the fold line 14, wherein the side part 13 is also pivoted by 180 °.
• the tab 17 is then put out of the actual opening and inserted into the grip hole 11. This state is shown shortly before its completion, and it can be seen that this design of the grip hole and the tab part 19 achieves a higher mechanical strength of the moving box and at the same time a more comfortable carrying of the moving box is achieved due to the wide contact surface.
• the tab part 19 can also be formed on the side wall part 10 in the region of the grip hole in order to take over the function shown in FIG. 2,
• the folding box shown in Fig. 4 is shown in its not yet fully assembled state. With 10 one of the smaller side walls is designated. 112 with the grip hole in the small side part 10 is designated.
• the side parts have extensions, which are designated by the reference numerals 20 and 16, 170.
• the extensions of the small side parts 10 are designed with a slot 15, which extends in the longitudinal direction of the carton, but does not go through to the adjacent folded edge 21.
• the corresponding distance is designated by 20, with 130 referring to the particularly critical stress point.
• extension part 140 is already in the final position, the extension part 20 shown on the right must still be placed on the other extension part. Then the two extension parts 16, 170 are also folded inwards, the outer parts being folded on the folded edge 180, being passed through the incisions 15 and being put back. The outer parts of the extension pieces 170 of the larger side walls 110 have cutouts which are provided with the reference number 190.
• Extension parts 16 and 170 of the large sides cutout 117 so that the folding of the carton is possible.
• the handle hole 11 with its upper limit is at a distance Hi from the edge of the carton.
• Extension parts 200 which extend from the edge and each have an extension of H, are folded together (turned inside out). Since H 2 is slightly larger "al Hi, the cardboard, the force zun spiritss from the fold of the grip hole on the folded parts 20 and transferred irn beau then de only after a certain deformation grip hole area to the south and transferred 10 under load.
• the partial carton shown in FIG. 5 is equipped with two lids which are partially opposite one another and are equipped with slots 110. In the state of the art, these are slots, the two flanks of which are designed parallel to one another.
• the curved curve merges into a slot base 13.
• the curve boundary 112 of the one cover is the straight boundary 111 of the other cover and vice versa.
• the end position is stable due to the slot base 113. Nevertheless, the folding box can easily be opened and used several times without the edges of the slot having to be deformed.
