Description

The invention relates to a collapsible and erectable reusable cardboard made of corrugated cardboard for Transporting goods in the upright position of the Cardboard boxes with the features of the generic term of Claim 1.

Such a folding box is in US-PS 44 05 077 described. This is where the crease and the Auxiliary fold so close to the ground that the folding of the Side parts is difficult because the corrugated cardboard in the folded side panels opposite the floor by almost Must be bent 180 °. Such an upset can on the one hand to breakage of the corrugated cardboard and on the other hand lead that the side parts have a tendency to themselves to erect. In the folded state there is Cardboard box of US-PS 44 05 077 no residual volume in which the folded side parts could lay down. The folded side parts are also from this Basically stand up more or less.

Since there is no residual volume in the folded carton exists, auxiliary parts such as Support parts to be transported back.

When erected, the side parts tend to Bulge when packing bulk goods or such  Cardboard boxes are stacked.

In FR-PS 4 72 157 is a collapsible box described for hats or other items. Such Boxes were not made from corrugated cardboard, but from Hard boxes or the like made.

On the FR-PS 4 72 157 there are four folds on two formed and cross opposite side parts not yourself. Fold folds away from the floor in the folded box into a usable one Volume. Auxiliary folds are not provided.

To strengthen the erected side panels is after the FR-PS 4 72 157 in the area of the upper edges of the Side parts provided a frame, which is there by means Can snap buttons or the like fix. The frame can the upright position of the side parts to back up. From vertical, introduced from the lid Loads such as those encountered when stacking occur, the frame relieves the side parts Not.

The box is also regarding disposal inconvenient as they are different Materials exist that are separated during disposal should be. With such a box, this plays not a crucial role, because the box for durable packaging. With a transport box on the other hand, there is a separate structure for disposal important.

In DE-AS 10 63 522 are foldable Permanent packaging sleeves described. With these is the  Cover with grooves on the tenon of the end walls. For a structure made of corrugated cardboard is suitable Construction not.

In US-PS 44 11 373 is a collapsible Support part made of corrugated cardboard described in erected state in a reusable folding box Stabilization of the side parts can be used. The Support part must be folded out before folding the folding box can be taken from this as it is folded Condition does not form space for receiving the support part. The support member must therefore be separated from the Folded cardboard can be transported back.

A folding box is described in DE-GM 78 09 215. However, this has a when folded much larger footprint than the floor in unfolded condition. To return any Pieces, this folding box is unsuitable. Become frequent Cardboard boxes transported on standard-sized pallets. To the Return of a box according to DE-GM 78 09 250 then the palette is no longer suitable because the Footprint of the folded cardboard box essential is larger than that of the soil.

The object of the invention is to provide a reusable carton propose the preamble of claim 1, which itself can be easily folded up and erected Green area in the folded state is just as large as when erected and its volume in folded state much smaller than in is erected state, means being provided which the side parts of the erected folding box stabilize and in the remaining volume of the folded cartons can be transported with this are.

According to the invention, the above task is for a carton  initially mentioned type by the characteristics of characteristic part solved.

This reusable box can be used after it has been emptied fold up in a few simple steps. For this he will by means of the corner folds, the crease folds, the Folding folds and the auxiliary fold or the auxiliary folds folded up. All four then work Side parts over the floor so that they are in this are essentially parallel. The volume of the folding box is small in this folded state Comparison to the erect state.

When folding, nothing needs to be changed on the floor will. The floor still forms the base of the Folding boxes. Accordingly, the return transport of the Folding boxes are made on the same pallet on which the transport was also carried out. The floor can also be direct attached to the pallet.

That in the folded state of the folding box in this because of the folding folds spaced from the floor the remaining volume is taken up by the collapsible Support part on. This can be done in this way Transport folded folded cardboard back. in the The erected condition of the folding box stabilizes it used support part the side parts.

The configuration according to claim 2 ensures that corner folds or auxiliary folds only on three side parts are provided. One of the side parts is from such oblique folds free. This keeps the folding box in the erected state - regardless of the support part - stand more stable. In addition, the folding of the Cardboard boxes are simplified because the folding process both by pushing in and pulling out the two Auxiliary folds can take place.  

The embodiment according to claim 4 has the advantage that two Side parts of oblique crease or auxiliary folds are free. Aid wrinkles are not necessary Execution.

The second longer side part is optionally together with the first longer side panel can be folded outwards and then after folding the other side parts over the Foldable floor, or it is over the floor from the start foldable.

The embodiment according to claim 5 relates to cutouts on the upper edge of the longer side parts. This means that even at greater heights of the side parts on which the Wrinkles preferably run at an angle of 45 ° Crossing the folds is avoided in this Execution would prevent folding.

The cutouts are preferably so long that they are Fold the shorter side parts over the floor enable. The greater the height of the folding box, the longer the cutouts are dimensioned. At the the folded cardboard hardly disturbs the cutouts, after the support part in the erected cardboard box is used.

This preferably extends beyond the open one Side parts or the erected folding box used support part the upper edge of the side parts. The The lid then sits on the support part. The side parts are then of vertical acting on the lid Relieves stress.

An advantageous embodiment of the cover is in Claim 8 specified, with which the return transport the lid is simplified.

The bottom of the folding box is usually the same size  a usual, standardized range, for example one Width of about 800 mm and a length of about 1200 mm (Euro pallet), with a height of, for example, 700 mm. With these dimensions, the manual loading of the unfolded cartons can be difficult. To load to simplify, on at least one of the side parts a loading flap known per se may be provided. These can be the vertical slits of the Create side parts and, if necessary, the support part.

Suitable as a material for the folding box is one or multi-wall corrugated cardboard or solid cardboard. The above Fold through perforation lines, scratch lines or Roll lines determined.

A folding box has side parts ( 1, 2, 3, 4 ). These are connected to a bottom ( 5 ), which is formed by parts ( 6, 7, 8, 9 ) (see FIG. 3). The bottom ( 5 ) is attached to a pallet ( 10 ). It has a base area formed by the length (L) and the width (B).

There are corner folds ( 11, 12, 13, 14 ) between the side parts ( 1 to 4 ). The side parts ( 2, 3 ) are permanently glued or clamped together by means of a tab ( 15 ).

A crease ( 16, 17, 18, 19 ) is formed on each of the side parts ( 1 to 4 ). The folds ( 16 to 19 ) begin at points ( 20, 21, 22 and 23 ) of the relevant corner folds ( 11 to 14 ) and form an angle (W) of approximately 45 ° with them. The locations ( 20 to 23 ) lie at a small, equal distance (h) above the floor ( 5 ) compared to the height (H) of the folding box. Between the points ( 20 to 23 ), fold-in folds ( 24, 25, 26 and 27 ) run parallel to the floor ( 5 ) on the side parts ( 1 to 4 ).

An auxiliary fold ( 28 ) is additionally provided on the side part ( 1 ). This begins at the point ( 23 ) of the corner fold ( 14 ) of the side part ( 1 ), but not at the corner fold ( 11 ) of the side part ( 1 ) at which the crease ( 16 ) begins. The auxiliary fold ( 28 ) extends in the side part ( 1 ) at an acute angle (W 1 ) to the corner fold ( 14 ).

A supporting part ( 29 ) made of corrugated cardboard is provided for the folding box, which is shown in its collapsed state in FIG. 1b. Its length (Lb) corresponds to the length (L). Its height (Hb) is not greater than the width (B) of the folding box. Each of its collapsible sides ( 30, 31 ) corresponds in the stretched state to the width (B) of the folding box. When folded, the support part ( 29 ) has a thickness (d) which is approximately the same as the height (h). The support part ( 29 ) can be inserted into the folding box on the floor ( 5 ) in the folded state according to FIG. 1b. The support part ( 29 ) is provided for those cases in which the folding carton appears to be too unstable due to the folds ( 16 to 19 ) or the folding folds ( 26 to 27 ) and the auxiliary fold ( 28 ). It is then inserted with the sides ( 30, 31 ) extended into the folding carton and supports its side parts ( 1 to 4 ). The height (Hb) of the support part ( 29 ) need not be as large as the height (H) of the folding box. The height (Hb) of the support part ( 29 ) can, if the width (B) of the folding box allows it, also be greater than the height (H). The support part ( 29 ) then projects beyond the side parts ( 1 to 4 ) and increases the volume that can be packed in the folding carton.

Furthermore, a lid ( 32 ) made of corrugated cardboard is provided, which forms a peripheral edge ( 33 ). The height (Hc) of the edge ( 33 ) is approximately equal to the height (h). Its base area is essentially the same as that of the base ( 5 ). The lid ( 32 ) can be placed on the side parts ( 1 to 4 ). If the support part ( 29 ) projects beyond the side parts ( 1 to 4 ), the cover ( 32 ) can be placed on the support part ( 29 ).

The folding style of the folding box is essentially the following:

If the folding box is to be folded up from its unfolded position shown in FIG. 1a, the upper edge ( 34 ) on the crease ( 28 ) is pulled slightly outwards in the direction of the arrow (P 1 ). Conversely, the corner fold ( 14 ) is pressed inwards in the direction of the arrow (P 2 ). The side part ( 1 ) folds inwards around the fold-in fold ( 24 ) until the corner fold ( 14 ) lies against the fold-in fold ( 27 ) on the inside. The partial area lying between the crease ( 16 ) and the corner fold ( 11 ) lies on the partial area of the side part ( 1 ) lying between the crease ( 16 ) and the fold-in fold ( 24 ) until the corner fold ( 11 ) approximately parallel to the fold-in fold ( 24 ) lies. Accordingly, the other side parts ( 2, 3, 4 ) are taken along and fold over the floor ( 5 ) until the corner fold ( 12 ) is parallel to the fold ( 25 ) and the corner fold ( 13 ) is approximately parallel to the fold ( 26 ). The folded carton now has essentially only the height (h). The lid ( 32 ) can then be placed on it again (cf. FIG. 2).

The folding of the folding box is obviously easy to do manually. In principle, folding can be done with one hand. The empty, folded folding carton, in which the support part ( 29 ) may be inserted, can easily be transported back with its pallet ( 10 ) for refilling. It takes up little space and is nevertheless dimensionally stable. To refill the carton, simply remove the lid ( 32 ) and return it to its unfolded position. For this purpose, the side parts ( 1 to 4 ) are folded up and, if necessary, the support part ( 29 ) is inserted into it in the manner described.

In the embodiments according to FIGS. 4 to 9 the same reference numerals as used in the embodiment described above for the corresponding parts or fold lines. In this respect, reference is made to the above execution. Different from the exemplary embodiment described above in the exemplary embodiments according to FIGS. 4 to 9 are the positions of the folds or auxiliary folds on the side parts ( 1 to 4 ).

In the embodiment according to Fig. 4a and Fig. 6, the two folds ( 16, 17 ) are arranged on the shorter side part ( 2 ), which has the width (B), which is shorter than the length (L) of the side parts ( 1 and 3 ). The crease ( 16 ) begins at point ( 20 ) and extends at an angle (W) of 45 ° to the corner fold ( 11 ). The crease ( 17 ) begins at point ( 21 ) and extends at an angle of approximately 45 ° to the corner fold ( 12 ). With the usual dimensions, the folds ( 16, 17 ) intersect within the side part ( 2 ).

The folds ( 18, 19 ) run on the side part ( 4 ) as well as the folds ( 16, 17 ) on the side part ( 2 ). The crease ( 18 ) starts from the point ( 22 ) and extends at an angle of 45 ° to the crease ( 13 ). The crease ( 19 ) starts from the point ( 23 ) and extends at an angle of 45 ° to the crease ( 14 ). The side part ( 3 ) is free of crease lines.

On the side part ( 1 ) two auxiliary folds ( 28, 28 ' ) are provided. These start from the points ( 23 or 20 ) and extend at an angle (W 1 ) to the corner fold ( 14 or 11 ), this angle (W 1 ) being approximately between 20 ° and 35 ° and in particular 30 ° is.

If the folding box folded in FIG. 4a is to be folded up, then the side part ( 1 ) is first pulled outwards or pressed inwards. Both are possible due to the auxiliary folds ( 28, 28 '' ). After pulling out the side part ( 1 ), the side parts ( 2, 4 ) are moved inwards and then pushed further inwards. This is possible due to the folds ( 16 to 19 ). The side panel ( 3 ) then folds inwards over the base ( 5 ). Then the side part ( 1 ) is pressed inwards until all side parts ( 1 to 4 ) are pivoted about the folding lines ( 24 to 27 ) and are approximately parallel to the floor ( 5 ).

It is also possible to first push the side part ( 1 ) inwards over the base ( 5 ). The side parts ( 2, 4 ) follow this due to the folds ( 16 to 19 ). You then pull the side part ( 3 ) over the side part ( 1 ) until the side parts ( 1 to 4 ) again lie approximately parallel to the floor ( 5 ) above it.

Then the lid ( 32 ) can be put on as described.

In the embodiment according to FIGS. 7 to 9, the folds ( 16, 17 ) are provided on the longer side part ( 1 ) and the folds ( 18, 19 ) on the opposite, longer side part ( 3 ). The folds ( 16, 17, 18, 19 ) each extend at an angle (W) of approximately 45 ° to the corner folds ( 11, 14, 12, 13 ), from their locations ( 20, 23, 21, 22 ) they going out. The side parts ( 2, 4 ) are free of fold lines.

The folds ( 16, 17 and 18, 19 ) do not cross in the side parts ( 1, 3 ). In order to avoid such a crossing at the heights (H) provided in FIGS. 7a and 9, cutouts ( 35, 36 ) are provided on the upper edge ( 34 ) of the side parts ( 1, 3 ). The cutouts ( 35, 36 ) are so deep that the folds ( 16, 17 and 18, 19 ) meet at most on their base line ( 34 ' ). However, it is also possible that the folds ( 16, 17 or 18, 19 ) do not meet on the base line ( 34 ' ) of the recess ( 35 or 36 ).

The extent of the recess ( 35, 36 ) in the longitudinal direction (L) is so large that the side parts ( 2, 4 ) over the bottom ( 5 ), parallel to this, can be inserted, with them in the corner areas under the Grab cutouts ( 35, 36 ) adjacent areas of the side parts ( 2, 3 ).

In order to fold up the folded cardboard according to FIG. 7a, at least one of the side parts ( 1, 3 ) is first pulled outwards, which is possible due to the folds ( 16, 17 or 18, 19 ). The side parts ( 2, 4 ) then fold inwards, approximately parallel over the floor ( 5 ). Then the side part or the side parts ( 1, 3 ), which is initially pivoted outwards, is folded inwards over the base ( 5 ). Then the cover ( 32 ) can be put on.

If necessary, a loading flap known per se can be provided on all of the exemplary embodiments on one of the side parts ( 1 to 4 ).
