Description

Recyclable trolley case

The present invention relates to a reusable trolley case, a method for manufacturing the trolley case and its use.

In today's society, travel such as air travel - private or business - has become indispensable. Several days are often spent at the holiday home, especially when traveling by plane. It is not uncommon for travelers to come back home with more luggage because, for example, souvenirs are bought.

Before traveling home, additional luggage must be packed in such a way that it arrives safely at its destination. This is particularly important when traveling by air or by coach, as third parties sort the individual pieces of luggage and these are also exposed to an increased load capacity. For example, baggage that is checked in when traveling by air must typically be packed in suitcases.

However, there is not always enough space for additional luggage in the luggage. Therefore it is sometimes necessary to buy an additional piece of luggage, for example a suitcase, for quite a bit of money in order to be able to pack the additional luggage correctly. If you travel regularly, the number of pieces of luggage available at home may grow continuously.

It is therefore the object of the present invention to provide an inexpensive item of luggage which can be reused. The piece of luggage should only take up little space from manufacture to sale and should therefore be easy to transport, store and stack. It should be stable enough to to protect the contents well for at least one trip. However, the item of luggage should also offer at least a level of convenience in terms of its ability to be transported, as is known from existing items of luggage. And if the piece of luggage is no longer needed, it should at least for the most part, ideally completely, be easy to recycle.

Surprisingly, this complex task could be achieved with a reusable trolley case (1) comprising a folded, lockable container (2), a handle (4), at least one roller holder (6) and at least one roller (7), wherein

- the container (2) is based on a common flat part (26) with front (21), rear (22), two side surfaces (23), underside (24) and a large number of tabs (27), - the container (2 ) has a top (25), the top

(25) is part of the common flat part (26) or of a further element arranged on the flat part (26) of the container (2), and

- The container (2), the roll holder (6), the handle (4) and optionally the at least one roll (7), made from cardboard and / or punched from cardboard, wherein

- The handle (4) is integrated or sunk in the container (2) in a position A and protrudes out of the container (2) in a position B, whereby the handle (4) can be reversibly changed from position A to position B.

What is also claimed is a method for producing the rolling suitcase (1) according to the invention, wherein i) the common flat part (26) of the container (2) made of flat cardboard is removed and the front side (21), rear side (22),

Side surfaces (23), underside (24), possibly upper side (25) and the plurality of tabs (27) of the container (2) are delimited from one another by creating a fold line, with at least one opening (8) being created in the flat part (26), if necessary, ii) the at least one roller (7 ) attached to the roll holder (6), in particular clamped, and iii) the front (21), back (22), side surfaces (23), underside (24), optionally the top (25), as well as the multitude of Tabs (27) are folded to form the container (2) and the container (2) is optionally closed, and iv) if the top (25) of the container is not part of the common flat part (26), the top (25) is put together with a large number of tabs (27) and the further element to be arranged on the container (2) removed from flat cardboard, created fold lines and folded to the top (25) and that

Element arranged on the container (2), wherein steps ii) and iii) can be carried out in any order. In addition, the use of the rolling suitcase (1) according to the invention as a rolling suitcase for transporting objects is also claimed, in particular for transporting objects once or only a few times.

The trolley case (1) according to the invention, the trolley case (1) produced according to the invention and the use according to the invention of the trolley case (1) surprisingly have many advantages. The rolling suitcase (1) according to the invention is inexpensive to manufacture and can be manufactured at the factory as a thin, packaged rolling suitcase (1 *) and transported, stored and stacked in an unfolded or flat-folded, ie folded, form as a semi-finished product in a simple and space-saving manner. For example, every hotel reception - or even every hotel room - can use the folded and packed trolley case (1 *), which can be bought, folded, packed and used as a full-fledged piece of luggage by anyone without prior knowledge. The folded flat part (26) of the container (2) can, respectively, without tools such as a folding box. Folding box easily folded into a fillable and closable container (2), ie joined together, respectively. be composed. The at least one roller (7) can easily be inserted into the roller holder (6) and the handle (4) can be reversibly brought into the correct position. The container (2) - typically in the form of a folded, ie assembled, folding cardboard box - can be packed, closed, transported and, for example, at an airport with the material to be transported, such as items of clothing, souvenirs and / or other goods intended for everyday use. or the bus terminal. If necessary, it can also be closed with adhesive tape, a tape, a safety strap or a belt and / or covered with a plastic film.

As a result, the trolley case (1) according to the invention does not differ from conventional trolley cases, at least when it is first used. However, it is cheap to set up and buy. After the trip, the container (2) can be folded up again so that the trolley case (1) can be stored to save space. If the trolley case (1) is no longer required, it can be disposed of in a simple manner, for example in a cardboard recycling plant, after the first use - or after a few additional uses as a trolley case - and thus reused.

With the method according to the invention, the rolling suitcase (1) according to the invention can surprisingly be produced in a simple manner. It is particularly advantageous that the rolling case (1) is factory-made as a semi-finished product in the form of a folded and packaged rolling case (1 *) can be manufactured and transported to the destination. The folded and packaged trolley case (1 *) can be transported and stored in a particularly space-saving manner. If the trolley case (1) is then required, it can be easily assembled using the packaged trolley case (1 *) without prior knowledge. The container (2) can typically be folded up like a folding box. If necessary, sides and flaps can also be glued to one another, for example by means of double-sided adhesive tape, it being possible for the adhesive tape to be attached at the factory to one side at the location to be glued.

US-A-2010/0001054 discloses packaging arrangements for moving a product in a box, the box being arranged on a tray having at least one roller which facilitates moving the box. Thus, the box does not have a stable underside and the roller is not attached to the box. The disclosed embodiments have a handle in the form of an opening attached to the box or as a conventional telescopic handle made of metal with a handle insert, which makes it easier to attach the telescopic handle to the box. The handle insert and the telescopic handle are arranged within the box and adjacent to at least one side wall of the box. A handle made of cardboard which can be reversibly changed from a position A integrated or recessed in the container (2) into a position B protruding from the container (2) is not disclosed.

WO-A-2006/053921 relates to a case with wheels and a storage body with a handle, and an opening through which objects can be inserted into or removed from the interior of the storage body. The case and the handle are formed by folding using a sheet material. The handle is designed so that it can be grasped by one hand of the user in the upright position. However, the handle cannot be reversibly integrated or sunk into the case, which means that it can easily be destroyed during transport or even separated from the case. The case is also made from two different flat materials that are joined together. Thus, the case does not consist of a flat common part. As a result, the case has additional weak points which can be torn open during transport and the material contained in it can be lost.

DE-A-10 2012 211 563 describes a transport device which has a foldable or folded container, a rolling element which is attachable or attached to the container and has a roller, the roller being made of a recycled, recyclable and / or biodegradable material , for example from cardboard and / or paper, or made of wood. The transport device is typically in the form of a wheeled suitcase with a handle, the handle being in the form of an opening in the elongated rear wall of the wheeled suitcase. The handle cannot be integrated or recessed into the folded container. As a result, it can be destroyed during transport or even separated from the case.

The trolley case (1) The trolley case (1) according to the invention is made entirely or for the most part from cardboard and is particularly suitable for one-time or only a few uses. If the trolley case (1) is no longer needed, the parts made of cardboard can be recycled, ie reused, in a cardboard recycling plant. Parts that may not be made from cardboard are preferably made from other recyclable materials so that the entire trolley case (1) can be recycled. The rolling suitcase (1) typically has the same or similar mass as conventional rolling suitcases. However, it is also possible for the rolling case (1) to differ significantly in height, width and / or depth from conventional case dimensions. Typical dimensions are, for example, 50 x 40 x 20 cm or 85 x 50 x 30 cm.

The container (2) of the rolling suitcase (1) can be closed, i.e. it can only be closed reversibly, i.e. non-destructively, using an insertable flap and / or a Velcro fastener. Alternatively - or additionally - one side, for example the front side (21), and / or a flap can be closed with an adhesive tape, for example with a double-sided adhesive tape, with at least one adjoining area of the container (2). Gluing is then typically done reversibly with a pressure sensitive adhesive (PSA) and / or - depending on the tab (27) - irreversibly, i.e. at least one top layer of the cardboard is torn out when the adhesive layer is opened. However, the container (2) can also - additionally or alternatively - be surrounded by a belt and thus closed. The container (2) is preferably in the form of a square, straight prism.

The reusable trolley case (1) according to the invention comprises a folded, lockable container (2), a handle (4), at least one roll holder (6) and at least one roll (7), the roll holder (6) being attached to the container (2) is or is part of the container (2) and the role

(7) engages in the roll holder (6). The container (2) is based on a common flat part (26) with a front side (21), a rear side (22), two side surfaces (23), a respective underside (24) and a large number of tabs (27). The container (2) also has a top side (25), the top side (25) being part of the common flat part (26) or of a further element arranged on the flat part (26) of the container (2), the Element preferably in the form of a pull-out rail (5) or a further layer (9) which is arranged on the outside of the rear side (22) and, for example, completely or partially covers the pull-out rail (5). In addition, the container (2), the roll holder (6), the handle (4) and, if necessary, the at least one roll (7) are made from cardboard and / or punched from cardboard. The handle (4) is integrated or sunk in the container (2) in a position A and the handle (4) protrudes from the container (2) in a position B, the handle (4) being reversible from position A to position B. can be changed

The term “integrated” is understood to mean that the handle (4) is part of the container (2) and does not protrude beyond its external dimensions, for example when the handle (4) is punched out of the rear (22) apart from a few folded edges and as a result, it can be opened reversibly and pushed back into the rear side, as shown in FIG. 2. And the term "recessed" means that the handle (4) is not part of the container (2), but was added to the container (2) as an additional element, but in position A essentially depends on the external dimensions of the container ( 2) covered and, for example longitudinally, can be pulled out reversibly to position B. Exemplary embodiments are shown in FIGS. 7a-d and 8a-d.

The container (2) of the rolling suitcase (1) is based on a common flat part (26) which is typically removed, in particular punched, from flat cardboard. Ideally, the front (21), the rear (22), the two side surfaces (23), the underside (24), possibly the upper side (25), and the large number of tabs (27) are separated from each other by means of fold lines, ie fold edges so delimited that they can be easily folded. The flat part (26) can have any shape as long as the individual sides with the tabs face the container 2. Can be folded. The flat part (26) - or a part thereof - can consist of one or more layers of cardboard.

The underside (24) of the container (2) - and thus of the trolley case (1) - is sufficiently stable to be used as an independent underside of the trolley case. Thus no additional floor is required, as is the case with US-A-2010/0001054. The underside (24) also has arrangements for attaching the at least one roller (7) and the roller holder (6) - provided this is not part of the common flat part (26) - whereby the at least one roller (7) is attached to the Container (2) is arranged. The top (25) of the folded container (2) is arranged on the side opposite to the bottom (24). The handle (4) is typically attached to the rear (22) of the rolling suitcase (1). In the lower area of the back (22), respectively. at least one roller (7) is usually attached to the area of the underside (24) which is connected to the rear side (22). The front side (21) is located on the opposite side of the rear side (22) and the two side surfaces (23) are arranged between the front side (21) and the rear side (22). The front side (21), the rear side (22) and the two side surfaces (23) are in contact with the lower side (24) at one folded edge and, if necessary, with the upper side (25) at the opposite folded edge.

Typically, the width of the front (21) and the rear (22) is greater than the width of the side surfaces (23). However, it is also possible for the side surfaces (23) to be wider than the front side (21) and the rear side (22).

The at least one roller (7) is attached to at least one point on the underside (24) of the trolley case (1) - preferably in the area of an edge to the rear (22). The roller (7) can have an elongated dimension and For example, they extend over more than half the edge length of the underside (24) in order to ensure sufficient stability with a roller (7). Alternatively, for example, two rollers (7) are arranged next to one another and in the end area of the edge length. However, it is also possible for the trolley case (1) to have three or four rollers (7) so that it can also be conveniently moved in a vertical position.

If the trolley case (1) is angled so that only one roller (7) or two adjacent rollers (7) of the trolley case (1) touches the floor, the trolley case (1) with the handle (4) can be moved like a conventional trolley case to be pulled.

The handle (4) of the trolley case (1) enables the trolley case (1) to be easily held with one hand and pulled over the floor thanks to the rollers (7) attached to the lower area of the container (2) . The handle (4) can be a reversibly extendable and / or foldable handle and can thus be integrated into the trolley case (1). Alternatively, the handle (4) can be reversibly attached to the trolley case (1) or the handle (4) can be in the form of at least one opening into which at least one hand can be inserted. If the handle (7) can be pulled out reversibly, it is typically attached to at least one pull-out rail (5), in particular on two pull-out rails (5), and preferably in one piece. In a preferred embodiment of the rolling suitcase (1) the cardboard is based on cellulose, wood pulp and optionally waste paper and has a mass per unit area of at least 225 g / m ² , preferably at least 500 g / m ² , measured according to DIN 6730: 2017-09 . The cardboard is preferably cardboard, corrugated cardboard, corrugated cardboard, cardboard box, pressed cardboard, wooden cardboard and / or gray cardboard role (7), can consist of the same or different cardboard. The same applies to the optional at least one guide element (3) and the optional at least one pull-out rail (5). The cardboard can also be selected in such a way that the individual components of the rolling case (1) such as the container (2), the roll holder (6) and, if applicable, the handle (4) have the appropriate stability. It is also possible - for example, the back (22) of the container (2) - to be reinforced by a second or even third layer of cardboard. The rollers (7) can be conventional rollers, such as those used, for example, in known wheeled suitcases. After removing the rollers (7), the trolley case (1) can be recycled. So that the trolley case (1) can be recycled as completely as possible, it is extremely advantageous if the rollers (7) can also be recycled. Thus, the at least one role (7) of the trolley case (1) is preferably based on a renewable raw material, a recyclable raw material and / or on rubber, the renewable raw materials preferably cardboard, wood, cork and / or vegetable fiber; and the recyclable raw materials, preferably metal and / or plastic, such as polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polycarbonate and / or their mixed, co- or block copolymers , represent; and rubber is preferably an elastomer such as natural or synthetic latex, rubber, ethylene-propylene-diene rubber (EPDM), and / or SBR. This means that the roll (7) - and thus the entire trolley case (1) - can also be recycled, even if the roll (7) is not made of cardboard.

The rollers (7) can have a diameter of, for example, 2 to 15 cm, in particular 3 to 10 cm. The width, respectively. The length of the rollers (7) depends in particular on whether only one roller (7) or two or more rollers are arranged per edge length. Will only one role (7) used, their length - depending on the edge length - be for example 15 to 45 cm. If two rollers (7) are arranged next to one another, their length can be, for example, 1 to 10 cm, in particular 1.5 to 6 cm.

In a further preferred embodiment of the rolling suitcase (1) the handle (4) is

- Formed from the flat part (26) of the container (2) and preferably foldable, as shown by way of example in FIGS. 2, 5a and 6; or

- Integrated in a flat pull-out rail (5) which, in position A, is wholly or partially arranged between the back (22) of the container (2) and a layer (9) arranged on the outside of the back (22), the pull-out rail ( 5) with the handle (4), preferably in the form of an opening (8) in the flat

Pull-out rail (5), in position A between the rear side (22) and the layer (9), can be lowered and reversibly shifted from position A to position B, in particular slidingly shifted and thus drawn or respectively. can be pushed, the handle (4) preferably in the form of an opening (8) in the

The pull-out rail (5) is integrated and / or the handle (4) can be opened out of the pull-out rail (5), as shown by way of example in FIGS. 7a-d, 8a-b, 9b and 10b; and / or arranged on a pull-out rail (5), the pull-out rail (5), which is preferably made of cardboard, is guided by means of at least one guide element (3), the guide element (3) being arranged on the container (2) and / or part of the container (2).

The trolley case (1) with the handle (4) can be moved in a comfortable manner, in particular pushed or. pulled, without having to carry the trolley case (1). If the handle (4) is formed from the flat part (26) of the container (2) and can preferably be opened, the handle (4) is usefully attached to the rear side (22) of the container (2) and can be reversibly integrated into this and again be opened. This allows a particularly efficient manufacture of the handle (4) without additional elements. The handle (4) can also be easily opened and closed. When it is closed, it is fully integrated into the rear (22) and has no disruptive elements. In this embodiment, at least the rear side (22) preferably comprises a further layer of cardboard to prevent objects from falling out, this further layer of cardboard being applied to the rear side (22) at the factory or when folding, ie assembling, the container (2) can be.

If the handle (4) is arranged on a pull-out rail (5) and guided by means of at least one guide element (3), the handle (4) can be pulled out in a simple manner as with conventional trolley cases and - for example, for transporting the trolley case (1) in the bus, car, plane, train or ship - be sunk back into the trolley case. Once the handle (4) and the pull-out rail (5) have been pulled out, smaller trolleys (1) can also be easily pulled or pushed. Depending on the specific embodiment, it is helpful if the guide rail (3) and the pull-out rail (5) with handle (4) are covered by a further layer (9) and thus protected, as in Fig. 7a-d and Fig. 8a -b shown. This typically involves fastening the guide rail (3) and the pull-out rail (5) with the handle (4) to the rear wall (22) of the container (2), as well as the subsequent covering of the guide rail (3) and the pull-out rail (5) with the other layer (9) carried out at the factory.

If the handle (4) is integrated in a flat pull-out rail (5) and is arranged in position A between the rear side (22) of the container (2) and a layer (9) arranged on the outside of the rear side (22), the Layer (9) completely cover the pull-out rail (5) - except for a part for pulling out the pull-out rail (5). Alternatively, the layer (9) only covers lateral guide elements, ie at least one protruding element (51), but not the larger part of the pull-out rail (5). In this embodiment, this is preferably covered with a further layer of cardboard in order to increase the stability of the pull-out rail (5). The thickness of the further layer of cardboard typically corresponds to the thickness of the layer (9), as a result of which the surfaces of the arranged layer (9) and the pull-out rail (5) do not differ. This embodiment is preferably used with larger trolley cases (1), in which case a hinged handle (4) is no longer necessary.

If the handle (4) is arranged on a pull-out rail (5), the pull-out rail (5) can consist of one pull-out rail or two pull-out rails arranged parallel to one another. If two parallel pull-out rails are used, the stability of the connection between the handle (4) and the trolley case (1) is increased. Alternatively, a flat pull-out rail (5) is inserted, as shown for example in Fig. 9b and Fig. 10b. If a pull-out rail (5) with at least one guide element (3) is used, the guide element (3) preferably consists of a further layer of cardboard which is connected, in particular glued, to the rear side (22) of the container (2). The guide element (3) can be attached to the inside or outside of the rear side (22); and / or the guide element (3) is preferably formed from parts of the rear side (22), the at least one guide element (3) at least partially enclosing the at least one pull-out rail (5) and / or the at least one guide element (3) in the at least one pull-out The rail (5) engages so that the at least one pull-out rail (5) with the handle (4) can be reversibly at least partially pulled out of the rear side (22) of the container and pushed back in again. If the guide element (3) is formed from parts of the rear side (22), for example rectangular elements can be punched and folded vertically so that three sides of the elements are severed and the fourth side is folded with a vertical orientation. These elements can now be punched and folded in such a way that the fold lines are arranged alternately on the left and right-hand side and the distance between the fold lines is the width of the pull-out rail (5). If these elements are then folded inwards and outwards alternately, the result is the guide element (3) for receiving the pull-out rail (5).

The at least one pull-out rail (5) preferably has

- At least one protruding element (51), for example in the form of a barb in the pull-out direction, in order to limit the distance with which the at least one pull-out rail (5) can be pulled out of the guide element (3), the protruding element (51 ) is limited by a stopper of the at least one guide element (3), and / or

- At least one tab (52), and when the pull-out rail (5) protrudes from the container (2) in position B, the tab (52) can reversibly lock the pull-out rail (5) in position B. A preferred, exemplary embodiment is shown in FIGS. 7a-d, 8a-b, 9a-b, and 10b.

In a preferred embodiment, the pull-out handle (4) and the at least one pull-out rail (5) are molded in one piece and the handle (4) is thus part of the pull-out rail (5). They are preferably made from cardboard, in particular punched from cardboard. This doesn't allow just one easy to manufacture, but also to be recycled together with the other parts of the cardboard trolley case (1).

In a particularly preferred embodiment, the role (7) of the trolley case (1) is based on an inner area (71) and an outer area (72), the inner area (71) consisting of at least one layer, preferably several - for example 3 to 10-planar layers arranged one on top of the other, for example made of honeycomb cardboard, are formed, the layer or layers being arranged perpendicular to the axis of the roll (7). The axis preferably runs through the center of the inner area (71) of the roller (7), i.e. the rotating roller (7) rotates with or around the axis. The outer area (72) is in the form of a sleeve, respectively. of a tube into which the inner area (71) is inserted with an accurate fit, the inner area (71), and optionally the outer area (72), of the roll (7) being made of cardboard.

The outer area (72) can be based on cardboard, which is preferably coated with a water-repellent layer such as paint, wax and / or paraffin, or made of another, preferably water-repellent material, which is also insensitive to abrasion, for example plastic . This embodiment allows the roll (7) to be manufactured - at least for the most part - from cardboard with significantly improved water resistance and stability, for example against mechanical wear, of the roll (7). If the outer area (72) is not made of cardboard, the entire roll (7), including the outer area (72), can usually be recycled because small amounts like the outer area (72) can be filtered out in a simple manner. In another preferred embodiment of the rolling case (1), the axis of the at least one roller (7) for fixing the roller (7) engages in the at least one roller holder (6), the roller holder (6)

- In the lower area of the rear side (22), in the lower area of the side surfaces (23) and / or on the underside (24) of the container

(2) is attached, in particular glued;

- Is formed by at least one opening (8) in at least one front (21), rear (22), and / or side surface (23) of the container (2) or by at least one opening (8) in at least one guide element (3) ; and or

- into which at least one guide element (3) is inserted, the roller holder (6) preferably having a protruding element (61), in particular in the form of a barb, the protruding element (61) preferably being in a slot in the guide element (3) is locked.

The at least one roller (7) is preferably fixed on both sides by a roller holder (6), a roller holder with knobs on both sides, respectively. can surround the axis of a roller (7) and so can accommodate the roller (7) on both sides. Alternatively, a roller holder (6) is attached to both sides of the roller (7), around the axis, respectively. to fix the role (7) optimally. If the trolley case (1) comprises two or more rollers (7) which are arranged side by side, a roller holder (6) can be arranged between two rollers (7) and thus accommodate a roller (7) on both sides.

If the trolley case (1) comprises two or more rollers (7) which are arranged side by side, a roller holder (6) can be arranged between two rollers (7) and thus accommodate a roller (7) on both sides. If the roll holder (6) is attached in the lower area of the rear side (22), in the lower area of the side surfaces (23) and / or on the underside (24) of the container (2), the roll holder (6) is preferably in the form of a separate one Element, which is typically attached when assembling the rolling suitcase (1) at a suitable location, which is ideally marked. The roller holder (6) can have a type of knob which can grip laterally into the center of the roller (7), ie into the axis of the roller (7). The axis of the roller (7) has a recess so that the roller (7) can grip into the nub of the roller holder (6). Alternatively, the roller holder (6) has a recess and the axis of the roller (7) can form a nub. Both sides of the roller (7) are typically designed in the same way. In a further embodiment, a separate axle is used which engages through the center of the at least one roller (7) and which is attached to the roller mounts (6). The axis can be in the form of a cardboard sleeve with a layer thickness of, for example, 3 to 4 mm and an outer diameter of, for example, 1.5 to 2.5 cm.

Is the roll holder (6) through at least one opening (8) in at least one front (21), back (22), and / or side surface (23) of the container (2) or through at least one opening (8) in at least one guide element (3), the axis of the roller (7) - typically on both sides of the roller (7) - is designed in the form of protruding knobs which engage in the respective openings (8) of the roller holder (6). The roller holder (6) is a part of the container (2) and / or part of the guide element (3), the at least one opening (8) typically being created when the flat part (26) or the guide element (3) is in position, especially punched, is. If the roll holder (6) is inserted into the at least one guide element (3), the roll holder (6) is usually a separate element, which is inserted into the guide element (3) when assembling the rolling case (1). The cantilevered element (61) of the roller holder is designed, for example, in the form of a barb, the cantilevered element (61) preferably snapped - and thus fastened - in a slot in the guide element (3). The cantilevered element (61) attaches the roller holder (6) to the guide element (3) and prevents the roller holder (6) from falling out or being displaced upwards by the forces acting on it.

The procedure

In the method according to the invention for positioning the rolling suitcase (1) in a first step i) the common flat part (26) of the container (2) is removed from flat cardboard, in particular punched out, cut out, and the front side (21), rear side (22 ), Side surfaces (23), underside (24), possibly the upper side (25) - that is, if this is not part of a further element to be arranged on the container (2) - as well as the plurality of tabs (27) of the container (2) are delimited from one another by creating a fold line, that is to say folded edge, with at least one opening (8) being created in the flat part (26) if necessary. The fold line is typically created with a tool or machine, especially during the punching process for removing the flat part (26) from the flat cardboard, so that the individual pages and flaps can be folded quickly, easily and at the correct location. This step is usually done at the factory. The flat part (26) obtained is then combined with the at least one roller (7) and - if available as separate components - with the handle (4), the at least one roller holder (6) and, if necessary, other optional elements such as at least one guide element (3) and at least one Pull-out rail (5), advantageously packaged to form a rolled-up case (1 *) that is folded flat and transported to the destination.

If the trolley case (1) is required, the flat folded case (1 *) is unpacked - if it is packed. In the following step ii) the at least one roller (7) is attached to the roller holder (6), in particular clamped, the axis of the at least one roller (7) typically engaging in the roller holder (6) to fix the roller (7). The axis can be designed in the form of lateral knobs attached to the roller (7) or as a separate element which engages in the roller bracket (6). The roll holder (6) in turn is arranged on the container (2) or is part of the container (2).

In a further step iii) the front (21), rear (22), side surfaces (23), underside (24), possibly the upper side (25) - provided this is not part of a further element to be arranged on the container (2) - As well as the plurality of tabs (27) folded to form the container (2) and - typically after the container (2) has been filled - the container (2) optionally closed. The closing can be done by inserting a last flap (27), by means of a - typically previously attached - double-sided adhesive tape, by means of single-sided adhesive tape, by means of pressure-sensitive adhesive, belt, rope or other fastening means and / or by inserting the trolley case (1) into a sack, in particular plastic sack or wrapping of the rolling suitcase (1) with packaging material, for example plastic.

If the top (25) of the container is not part of the common flat part (26), the top (25) is removed together with a large number of tabs (27) and the further element made of flat cardboard to be arranged on the container (2) , Fold lines created and to the top (25) - typically in the form of a lid - folded and then on Container (2) arranged. The element is preferably the guide element (3) or the further layer (9) which is arranged on the outside of the rear side (22) and, for example, covers the guide element (3) with the pull-out rail (5) - or a part thereof .

Process steps ii) and iii) for setting the wheeled suitcase (1) in position can be carried out in any order.

In a preferred embodiment of the method according to the invention, the handle (4) of the rolling suitcase (1), when the handle (4) is integrated in the container (2), is cut into the flat part (26), in particular punched, and opened for use ; if the handle (4) is integrated in a flat pull-out rail (5), the flat pull-out rail (5) is thus arranged between the back (22) of the container (2) and the layer (9) arranged on the outside of the back (22) is that the pull-out rail (5) with the handle (4) in position A between the back (22) and the layer (9) sunk and reversibly shifted to position B, in particular slidingly shifted and thus drawn, respectively. can be pushed. This is where the handle lies

(4) preferably in the form of an opening (8) in the flat pull-out rail (5). If the pull-out rail (5) has at least one protruding element (51), the pull-out rail is preferably guided by means of a guide element (3); and / or if the handle (4) with the pull-out rail (5) is guided by means of at least one guide element (3), with the pull-out rail

(5) is introduced into the guide element (3). If the handle (4) of the rolling suitcase (1) is integrated into the container (2) and can be opened reversibly, the handle (4) can typically be made at the factory created, in particular punched. It is helpful that the handle (4) consists of only one layer of the flat part (26) and another, inner layer of the container (2) covers the opened handle (4) flat. This embodiment of the handle (4) can be manufactured easily and does not require any further components such as a pull-out rail. The handle (4) is also already integrated in the container (2), which means that no additional work is required when assembling the trolley case (1). The handle (4) can be unfolded each time it is used and then folded back again so that it is integrated into the container (2) over a large area.

If the handle (4) of the rolling suitcase (1) represents at least one opening (8) in the container (2), the opening (8) can be punched into the flat part (26) in a simple manner and typically at the factory. This embodiment of the handle (4) does not contain any element which can be torn off or removed. In addition, no additional work step is required when assembling the trolley case (1).

Alternatively, the handle (4) with the pull-out rail (5) can be attached in at least one guide element (3) and on the back (22) of the container (2), so that the handle (4) with the pull-out rail (5) can be fitted in a conventional manner and Wise and especially reversible can be pulled out and retracted again. In a further preferred embodiment of the method according to the invention, the rolling case (1) has at least one guide element (3), i) removing the at least one guide element (3) from a further flat layer of cardboard, possibly provided with fold lines, and attaching it to the back ( 22) of the container (2) is attached, in particular glued and / or pushed in; ii) the at least one guide element (3) from the rear side (22) of the container (2) is cut or punched in such a way that the guide element (3) remains connected to the rear side (22) over at least one side, preferably indicated by a fold , or iii) lateral guide elements (3) are attached between the rear side (22) of the container (2) and the layer (9) arranged on the outside of the rear side (22), between which the flat pull-out rail (5) with handle (4 ) reversibly shifted from position A to position B, in particular slidingly shifted and thus drawn or respectively. can be pushed.

The guide element (3) allows optimal fixation and guidance of the pull-out rail (5), so that the fixation (5) can not only be easily attached, but can also be extended and retracted without any problems.

In another preferred embodiment of the method, the trolley case (1) has at least one pull-out rail (5), in particular a pull-out rail (5) with a handle (4), wherein i) the at least one pull-out rail (5), optionally with a handle (4) ), is removed, in particular punched out, from another flat layer of cardboard, and ii) the pull-out rail (5) on the container (2), preferably between the rear side (22) of the container (2), typically as a separate element, and the layer (9) is arranged in a reversibly sliding manner, for example in prefabricated openings. The pull-out rail (5) with handle (4) can be removed from the container (2) for further transport of the trolley case (1) and, if appropriate, attached to the container (2), for example by means of straps, and together with the trolley case (1) transported or as a separate element and separated from the trolley case (1) from Fland be worn. This allows the handle (4) with the pull-out rail (5) to be manufactured and used in a simple manner; or iii) the pull-out rail (5) is inserted into the guide element (3). Thus, the pull-out rail (5) is an integral part of the trolley case (1) and can be easily pulled out and stowed away again.

The pull-out rail (5) can have at least one tab (52), with the pull-out rail (5) reversibly in position with the at least one tab (52) when the pull-out rail (5) protrudes from the container (2) in position B B can be locked. If the pull-out rail (5) with handle (4) is to be stowed back in the trolley case (1), the flap (52) is folded back, whereby the lock is released and the pull-out rail (5) is conveniently placed back in the guide element (3), for example. can be pushed and stowed away.

By removing the pull-out rail (5), optionally with a handle (4) made of cardboard, and thus also being formed from cardboard, the pull-out rail (5) can be reused together with the cardboard trolley case (1).

In a particularly preferred embodiment of the method according to the invention, a) the flat part (26) of the container (2) removed from the flat cardboard is folded together with the at least one roller (7) and the handle (4) and the Roller holder (6), provided the handle (4) and / or the roller holder (6) are not part of the flat part (26), and optionally with the at least one guide element (3), the at least one pull-out rail (5) and / or the further layer (9) is packaged together, whereby a folded, packaged rolling suitcase (1 *) is obtained, and b) the folded, packaged wheeled suitcase (1 *) is put together to form a wheeled suitcase (1) if necessary by attaching the at least one roll (7) to the roll holder (6), in particular by clamping it, and the front (21), back (22), side surfaces (23), underside (24), possibly the upper side (25) and the plurality of tabs (27) folded to form the container (2) and the container (2) is optionally closed, and optionally the at least one guide element ( 3), the at least one pull-out rail (5) and / or the further layer (9) on the container (2), in particular on the rear side (22) of the container (2).

A folded and packaged trolley case (1 *) obtained in this way is an extremely suitable semi-finished product that can be transported, stacked and stored in a space-saving manner. It can also be assembled, that is to say, folded, easily and without prior knowledge to form a trolley case (1). After using the rolling case (1), if it has not yet been disposed of, it can be folded up again and stored as a rolling case (1 *) until it is next used. In a very particularly preferred embodiment of the method according to the invention, the roll (7) is produced by arranging at least one layer of cardboard, preferably several flat layers of cardboard, one on top of the other, forming the inner region (71) of the roll (7), the inner region (71) is inserted precisely into the outer area (72). The outer area (72) is typically in the form of a tube which protects the inner area. The outer area is advantageously treated with a water-repellent layer so that the trolley case (1) can also be used in the rain without any problems. This embodiment significantly increases the stability and water resistance of the roller (7). The usage

The trolley case (1) according to the invention and the trolley case (1) produced according to the invention are used in particular as trolley cases for transporting objects, in particular for one or only one transport, ie for 2 to 10 times, preferably 2 to 5 times of objects. The trolley case (1) is preferably used for trips such as air, bus, car, car, train and / or boat trips

If the trolley case (1) is used more than once, the trolley case (1) or at least the container (2) of the trolley case (1) can be folded up after use and stored in a space-saving manner. Before the next use, the container (2) is resp. the trolley case (1) then reassembled. This procedure is particularly advantageous when the reversibly assemblable parts of the container (2), respectively. of the rolling suitcase (1) are not glued, but merely plugged together, folded and / or reversibly connected to one another, for example by means of Velcro.

If the trolley case (1) is no longer used, it can - typically completely - be recycled. Thus, it is advantageously recycled as cardboard, i.e. reused, after use, if necessary after removing the at least one roll (7), provided the roll (7) is not made of cardboard. If the roll (7) is made of another reusable material, this can also be recycled. This increases the sustainability and thus the environmental balance of the trolley case (1). In addition, there is little or no waste.

The flat part (26) shown comprises a large number of lateral tabs (27). One or more tabs (27) can also be omitted and / or one or more tabs shortened and, for example, equipped with one or more adhesive strips. The person skilled in the art knows which tabs (27) are required for the stability required in each case and which can be omitted and / or shortened if necessary.

Analogously to FIG. 3a, FIG. 5a shows, by way of example, the trolley case (1) from FIG. 2, the front side (21) with the adjoining tabs (27) being open so that the opened container (2) can be packed. The tab (27) with the two openings (8) arranged on the longer edge of the front side (21) comes to lie directly next to the side surface (23) when the front side (21) is closed and reinforces it.

The handle (4) is, for example, unfolded from the rear side (22) and one roller (7) is arranged laterally on a roller holder (6) in the lower area of the rear side (22).

FIG. 5b shows an example of the opened trolley case (1) from FIG. 5a from the other side, so that the interior of the container (2) with the underside (24) is visible. The rollers (7) are covered by the roller holder (6) and attached to it. The roll holder is attached, for example, to both the underside (24) and the rear (22) by means of double-sided adhesive tape.

In the folded part of the container (2) with the back (22), top (25), bottom (24) and side surfaces (23), the tabs (27) are not shown. Analogously to FIG. 4, FIG. 6 shows, by way of example, an embodiment of a common flat part (26) of the container (2) from FIG. 2 and FIGS. 5a and 5b, which was removed, in particular punched, from flat cardboard. The flat part (26) comprises a front side (21), two rear sides (22), and two side surfaces

(23), (24) an upper side (25) with a plurality of tabs (27). On a side surface (23) and on the top (25) there are two openings (8) for carrying the trolley case (1). The handle (4) is cut into a rear side (22), which forms the outer rear side of the container (2), so that it can be opened in a simple manner. The other rear side (22), which forms the inner rear side of the container (2), covers the opening created by the unfolded handle (4) so that the contents of the container (2) remain protected. In the rebate area between the back (22) with an integrated handle

(4) and the underside (24) there are two openings (8) in which, after folding, a roll holder (6) with a roll (7) is attached (not shown).

On the other rear side (22) and on a tab (27) attached to it, lines parallel to one another are arranged by way of example, which indicate the presence of adhesive strips. These can be applied to the rear side (22) and the flap (27), for example in the form of a double-sided adhesive tape. When folding and after removing the protective layer, the two backs (22) and the

Tab (27) glued to a side surface (23).

The front (21), the side surfaces (23), the underside (24) and the upper side (25) also have further lateral flaps (27) in order to give the folded container (2) the desired stability. The flat part (26) shown comprises a large number of lateral tabs (27). One or more tabs (27) can also be omitted and / or one or more tabs shortened and, for example, equipped with one or more adhesive strips. The person skilled in the art knows which tabs (27) are required for the stability required in each case and which can be omitted and / or shortened if necessary.

7a, 7b, 7c, 7d show a further embodiment of the rolling case (1), in which the handle (4) is integrated in a flat pull-out rail (5) and protrudes in position B from the container (2). The pull-out rail (5) is locked by means of opened tabs (52). If the tabs (52) are folded back, the handle (4) can be reversibly pushed back from position B to position A and thus lowered.

The handle (4) can, for example, be opened out of the pull-out rail (5) from a lower position. This makes pulling the trolley case (1) easier because the person pulling does not have to lower himself as much.

The flat pull-out rail (5) with handle (4) is arranged between the rear side (22) of the container (2) and a layer (9) arranged on the outside of the rear side (22).

8a, 8b, 8c, 8d show a further embodiment of the rolling case (1), which can be opened and filled by opening the top (25). In order to be able to completely open the top (25) - designed in this form as a lid - as shown in FIGS is not visible. The flat pull-out rail (5) with handle (4) is analogous to FIG. 7a-d between the rear side (22) of the container (2) and one on the Outside of the rear side (22) arranged layer (9) attached.

Fig. 9a shows the pull-out rail (5) with the folded-in handle (4), made of a cantilevered element (51) and tabs (52) embedded in a flat, folded-together form in the guide element (3). The pull-out rail (5) is limited when it is pulled out by the protruding element (51) on the stopper of the at least one guide element (3).

The guide element (3) and the pull-out rail (5) are attached by way of example to the rear side (22) of the container (2) of FIGS. 7a-d and 8a-d and from the layer (9) as a protective layer - except for a part for pulling out the pull-out rail (5) - completely covered. Alternatively, the layer (9) has a larger recess and covers the layer of the guide element (3), the area in which the protruding elements (51) are and are guided, and optionally a lateral edge area of the pull-out rail (5). The area of the pull-out rail (5) which is not covered by the layer (9) can be reinforced with a further layer of cardboard in order to increase the stability of the pull-out rail (5).

The handle (4) is attached to the pull-out rail (5) and, for example, folded back. This embodiment is particularly suitable for smaller wheeled suitcases (1). With larger - and thus longer resp. higher - wheeled suitcases (1), the handle (4) does not have to be folded back. Thus, the foldable part can be left out. In this way, for example, the upper horizontal part of the pull-out rail (5) can serve as a handle (4) Fig. 9b shows the pull-out rail (5) pulled out of the guide element (3) with the handle (4) folded out, as shown as part of the rolling suitcase (1) in Fig. 7a-d and Fig. 8a-b. The protruding element (51) serves as a stopper when pulling out the pull-out rail (5) and the unfolded tabs (52) prevent the pull-out rail (5) from sliding back into the container (2), ie in position A.

Fig. 9c shows the layer (9), which the guide element shown in Fig. 9a (3) and the pull-out rail (5), if arranged on the back (22) of the container (2), except for a part for pulling out the Pull-out rail (5) - completely covered and thus protects. Fig. 10a shows the embodiment of the container (2) without a top (25).

The rollers (7) with axis are attached to the rear (22) and are not visible in the perspective shown.

FIG. 10b shows, analogously to FIG Lid is attached. If this guide element (3) with top (25) and pull-out rail (5) is attached to the rear (22) of the container (2) from FIG. 10a and covered with the layer (9) from FIG ) receive. The container (2) of FIG. 10a can be closed with the top (25), ie the lid, after the pull-out rail (5) has been sunk into the guide element (3). Fig. 11a shows an example of a handle (4) which is connected to two parallel pull-out rails (5). A cantilevered element (51) is arranged in the lower area of the pull-out rails (5). The pull-out rail (5) is inserted into the guide element (3) in the rolling case (1) and is limited by this. The guide element (3) is now advantageously so wide in the lower area that the pull-out rail (5) with the cantilevered element (51) can easily be guided up and down within the lower area. In the upper area of the guide element (3), however, this is tapered so that the protruding element (51) is too wide and prevents the pull-out rail (5) from being pulled out further.

11b shows an example of the rear side (22) of the container (2) with two guide elements (3), which are created when a surface is folded with guide elements (3) prepared by means of folding lines.

The area with the guide elements (3) prepared by means of folding lines can be a separate element which is attached to the rear side (22), in particular placed on top or glued on. This surface can, however, also be part of the flat part (26), as shown in FIG. 4.

Analogously to FIG. 11a, FIG. 11c shows, by way of example, another embodiment of the guide elements (3) arranged on the rear side (22).

These are shaped as simple rectangular flea bodies, which are typically attached, in particular glued, to the rear side (22). Fig. 12a shows an example of a roll holder (6) with an opening around the lower area of the roll holder (6) into which the lateral Nub of a roller (7) can be introduced. The roller bracket (6) has a cantilevered element (61) in the upper area. The shape of the roller holder shown is particularly suitable for insertion into a guide element (3), the insertion typically taking place from below. The cantilever

Element (61) attaches the roller holder (6) to the guide element (3) and thus prevents the roller holder (6) from falling out or being pushed upwards by the forces acting on it. The protruding element (61) can also have a different shape, for example a rectangular one

Shape, or it can be rotated 180 degrees.

The guide element (3) into which the roller holder (6) can be inserted can, for example, have a limitation that prevents the roller holder (6) from being pushed further upwards.

Fig. 12b shows an example of a roller (7) with an elongated dimension. The axis of the roller (7) has protruding knobs on both sides, which are inserted into the roller holder (6), whereby the roller (7) is fixed in such a way that it is fixed but can still rotate.

12c shows two rollers (7) which are based on an inner area (71) and an outer area (72), the inner area (71) being exemplarily composed of several superposed areas

Layers are shaped. These layers are arranged perpendicular to the axis of the roller (7), which passes through the center of the rollers (7). The outer area (72) of the rollers is typically in the form of a tube, into which the inner area (71) is precisely inserted, the inner area (71) and preferably also includes the outer area (72), the roller (7) are made of cardboard.
