Description

folding

The invention relates to a carton, their use and a method for producing the carton.

There are already various cartons known that serve to receive goods or packaged goods. In WO2005 / 075300 a rectangular or cube-shaped or six-sided folding or folding box is disclosed with a quadrangular plan, which has a bottom wall and six side walls. The side walls are hingedly connected to each other via bellows, so that the carton can be set from a flat position to a raised position. One of the side walls is hingedly attached to the bottom wall together with two bellows, with the bellows located at one end of the side wall, respectively.

The object of the present invention is to provide a carton, their use and manufacturing method in which the transportability and storage ability is improved and the inclusion of roundish intake material is ensured.

To solve the specified in claim 1 carton, their use in claim 10 and a method for producing a carton in claim 16 are proposed. Advantageous, optional training arise wholly or partly from the dependent claims.

The carton has a polygonal bottom wall and accordingly, hinged side walls, which surround the bottom wall in a closed row. The sidewall number is an even number and half of the sidewall number is an odd number. Furthermore, the bottom wall has a bottom hinge that extends from one corner to an opposite corner. This bottom hinge may be an embossed fold or crease line or edge. That means the bottom wall off an item is made. However, it is also possible that the bottom wall consists of two identical bottom wall parts. This means that the bottom hinge passes through the bottom wall and thus connects the two bottom wall parts together. The bottom wall also has at least two corners, preferably six corners, ie it represents a hexagon or a hexagon.

According to the invention at least one stop element is attached to each side wall below the bottom wall. The attachment of the stop elements on the side walls is preferably made by a material connection, such as gluing. The arrangement of the stop elements below the bottom wall is provided to prevent slipping down the bottom wall. This means that the stop elements represent a support or support surface for the bottom wall.

It is also expedient that the bottom wall has at least two adhesive tabs or other fastening elements which extend parallel to the bottom hinge. An adhesive flap length or fastener length corresponds to a side edge length of the bottom wall. The glue flaps or fasteners are disposed on opposite side edges of the bottom wall which are parallel to the bottom hinge or to the fold or crease line or edge. This means that the adhesive tabs or the fastening elements are formed on both sides of the bottom hinge or folding or bending line or edge. There may also be more than two adhesive tabs or fasteners. However, the glue flaps or fasteners may be located only on two side edges of the bottom wall that are parallel to the bottom hinge so that the box remains foldable.

Furthermore, it is expedient that the adhesive tabs or other fastening elements of the bottom wall between the side wall and the stop element are attached. This can preferably be achieved by means of a material connection. Conceivable but also non-positive or positive connections. The on the adhesive tabs or on the Attachment elements applied stop elements stabilize the connection between the bottom wall and the side wall row.

In a preferred embodiment, the stop elements, which are fastened to the adhesive flaps or other fastening elements of the bottom wall, are arranged over the entire side wall edge length. As a result, increased stability and load capacity is achieved, so that the carton can be loaded with more packaged goods or bulky goods.

In one embodiment of the invention, the stop elements are arranged flush with the respective side wall edge. Furthermore, all stop elements on the same height, so that the bottom wall rests flat on the stop elements. This ensures a right angle between side walls and bottom wall.

In a further embodiment of the invention, the side walls, the bottom wall and the stop elements of packaging material, preferably made of cardboard and / or paper are formed. Packaging material is understood as meaning a material from which the packaging material, i. the carton, exists. The packaging or the folding box are intended to protect the packaged goods, i. the goods, to enclose or hold together so that it is storable and / or transportable and / or salable. Under packaging material, for example, wood, paper, cardboard, glass, iron, aluminum, plastic, etc. can be understood.

It is also expedient that all side walls have the same height. Nevertheless, this is not absolutely necessary. The side walls can also have different heights. However, it should be noted that the lid would have to be adjusted accordingly, so that the goods or the packaged goods can also be sealed.

In a further embodiment of the invention has at the unfolded carton each edge angle or interior angle between the side walls at least 120 °. The angle depends on the number of side walls and / or the number of corners of the bottom wall. The internal angles or edge angles should all be the same to give a closed cylindrical and symmetrical shape. In a hexagon or hexagon, the internal angle or edge angle between the side walls 120 °, in a toe or decagon, however, it is already 144 °.

In addition to the carton also a use for folding and unfolding a carton is claimed. The carton comprises a polygon with an even number of corners. Half of the number of corners corresponds to an odd number. Furthermore, the carton has a bottom wall having a bottom hinge extending between two opposite corners and side walls, the two side walls which are parallel to the bottom hinge being pressed against each other.

In an example of use according to the invention, the bottom wall is folded or folded inwardly against the floor hinge by pressing the two side walls against each other. The bottom wall thus forms a pointed roof shape during collapsing and unfolding. The angle of the pointed roof shape decreases during folding and during unfolding. Accordingly, the angle is dependent on the distance of the opposite side walls, which are pressed against each other.

It is expedient that the side walls are pressed against each other until they rest tight or full or flat on the bottom wall. The angle of the pointed roof shape of the bottom wall is always smaller when folding, so that at the end of both bottom wall sides or bottom wall parts are dense or rich or flat on each other.

There are several ways to unfold the carton again. On the one hand, the flat folded carton According to the invention be opened by pressing against the two ends, whereby the bottom wall lowers. On the other hand, according to the invention, the folded flat folding box can be opened by pressing against the bottom hinge. Both options can also be used one after the other, ie first the bottom wall is lowered by pressing against both ends, so that subsequently the folding box is completely unfolded by pressing against the bottom hinge. The aforementioned ends are understood to mean the two corners or the two film hinges which, when folded, have a small or approximate inner angle or edge angle of 0 °.

In a further preferred embodiment, a buckling and / or bending of the bottom wall to the outside or down are prevented by the stop elements. The stop elements are therefore used as a support or bearing surface or as a stopper, so that the packaged goods or goods can be safely stored or transported in the carton.

Furthermore, a method for producing a folding box is claimed. Here, a polygonal bottom wall starting from one corner is provided to an opposite corner with a bottom hinge. Instead of the bottom hinge also a fold or crease line or edge can be embossed. Furthermore, both ends of a series of hinged side walls or side wall parts are connected together. Preferably, this is done by means of a material connection. Subsequently, the bottom wall is connected to the side wall row, wherein the bottom wall and the side wall row are formed with an even number of corners and half of the number of corners is odd.

The bottom hinge or the fold or crease line or edge can also be made by scribing the bottom wall along the desired folding or crease line or edge. Another possibility is that the bottom wall consists of two parts, ie two bottom wall parts and these parts are connected to each other with a hinge joint.

According to the invention, the side wall row is formed from separately produced side walls or side wall parts, which are lined up with hinge-like connections. This means that firstly all side walls are present individually and in a further processing step the individual side walls are connected to one another, so that a side wall row results. The side wall row is in turn connected at both ends, creating a closed cylindrical shape.

In a preferred variant of the method, stiff material is used for the side wall parts and by means of a flexible coating, the side wall parts are connected to one another such that film hinges are formed. For the side wall parts, for example, cardboard or cardboard is used. The individual side wall parts are placed with a constant or predetermined distance from each other in a row and then coated with a flexible coating such as a thin layer of paper. The distances between the side wall parts are preferably formed uniform. The coating creates hinges or flexible transitions between the fixed or stiff side wall parts, as a result of which the side wall row can be folded or folded at these points.

Another possibility according to the invention is that the side wall row of one piece, so in one piece, is formed and the fold or crease line or edge are embossed to form hinged joints. This means that in the sidewall row at certain and uniform intervals, the fold or crease line or edge is imprinted. Subsequently, the two ends of the side wall row are connected together. This can be achieved either by a material, non-positive or positive connection. In a variant of the method according to the invention, the side wall row is formed on both sides with adhesive tabs or with other fastening elements and at least one of the adhesive tabs or one of the fastening elements connected to the inside of the other side wall end. The adhesive tabs or the fasteners need not be glued, but can also by positive or non-positive connections, depending on the material used, the sidewall row to produce a closed cylindrical shape.

It is expedient that the bottom wall is introduced into the closed side wall row, so that in each case a side wall bears against a respective side edge of the bottom wall. Accordingly, the bottom wall has the same number of side edges as the side wall row side walls. The side edges of the bottom wall are also closely adjacent the side walls, so that the bottom wall with the side walls is a downwardly closed cylindrical shape.

It is also appropriate that at least two adhesive flaps or other fasteners are attached to the bottom wall parallel to and on both sides of the bottom hinge or parallel to and on both sides of the folding or folding line or edge. At least one glue flap or fastener must be attached or formed on each side edge that is parallel to the bottom hinge or parallel to the fold or crease line or edge. By means of these adhesive tabs or fasteners, the bottom wall is connected to the side walls.

Preferably, the adhesive tabs or other fastening elements of the bottom wall and / or the side wall row are attached to the inner sides of the side walls. As a result, the connections of the individual parts, in particular the side wall row with itself and the side wall row with the bottom wall, can not be seen from the outside. In a further variant of the invention, stop elements are attached to the inner sides of the side walls and / or on the attached adhesive flaps or fasteners to serve as a support for the bottom wall. The stop elements prevent slippage and the buckling of the bottom wall downwards. Furthermore, the stop elements are bearing surfaces for the bottom wall, so that the bottom wall forms a plane or a straight surface.

It is also possible to provide the carton with a lid. The lid may also have the characteristics of the carton, so that it is also collapsible like the carton.

Further details, features, combinations of features and effects on the basis of the invention will become apparent from the following description of preferred, exemplary embodiments of the invention and from the drawings. These show in:

Figure 8 bottom wall with adhesive tabs FIG. 1 shows an example of a folding box in a bird's eye view. The exemplary folding box represents a hexagon or a hexagon. For this purpose, six side wall parts 1 or side walls 1 or a side wall row are connected in such a way that a cylindrical shape is formed. The side walls 1 or side wall parts 1 are connected to each other via hinge joints or hinges 2 or folding or creasing lines or edges. At the lower end of the cylindrical shape, a bottom wall 3 is arranged. The bottom wall 3 has six side edges 4, between each of which a corner 5 is arranged. From a corner 5 to an opposite corner 5, a folding or bending line or edge 6 is embossed or a bottom hinge 6 is arranged. The bottom wall 3 may also consist of two individual parts, ie consist of two bottom wall parts 7, which are interconnected by means of the bottom hinge 5. In addition, the side edge length 4 of the bottom wall 3 corresponds to the length of the inner side wall edge eighth

In Fig. 2, the carton is shown in a bird's eye view from below. On each side wall 1 or on each side wall part 1, a stop element 9 is arranged. The stop elements 9 serve as a support surface for the bottom wall 3, so that the bottom wall 3 forms a plane. On the side walls 1, which run parallel to the bottom hinge 6, the stop elements 9 are formed over the entire side wall edge 8. Between these two side walls 1 and the associated stop elements 9 are projecting adhesive tabs 10 which are fixed to the bottom wall 3 or to the bottom wall parts 7, respectively. These adhesive tabs 10 also each form a hinge joint.

In Fig. 3 and in Fig. 4, the carton is shown as a top view or bottom view.

In Fig. 5, the carton can be seen during the Zusammenoder or unfolding. It will be the two side walls 1, which are parallel to the bottom hinge 6, pressed against each other (see arrows). The inner angles α of the two corners 5 or hinges 2 or hinged joints 2 of the side wall row, which border on the bottom hinge 6 in the unfolded carton, or the two ends 11 formed in the folded state are getting smaller. The inner angle ß of the remaining corners 5 or hinges 2 or hinged joints 2 of the side wall row, however, are getting bigger when folding. During unfolding and folding, the bottom wall 3 or the two bottom wall parts 7 are folded or folded inwards. As a result, the bottom wall 3 forms a pointed roof shape. The smaller the distance between the two opposite side walls 1, the smaller the angle between the two bottom wall parts 7 or the angle at the bottom hinge 6 of the bottom wall 3 becomes.

When the carton is folded, as can also be seen in FIG. 6, the angle between the bottom wall parts 7 is approximately 0 °. This means that the bottom wall parts 7 are directly close to each other and flat on each other. The angles at the two ends 11 of the folded carton also have an approximate angle of 0 °. Fig. 7 shows the top view of a lying collapsed carton. Fig. 8 illustrates the bottom wall 3 in detail as a separate

Part dar. It can be seen that the bottom hinge 6 from a corner 5, α to the opposite corner 5, α runs. The bottom hinge 6 connects either both individual bottom wall parts 7 or it represents a fold or crease line or edge 6 which has been embossed in the bottom wall 3. Parallel and on both sides of the bottom hinge 6 3 adhesive tabs 10 are projecting arranged on the side edges 4 of the bottom wall, so that they overlap with the respective side walls 1 and stop elements 9. These are formed according to FIG. 8 over the entire side edge length. LIST OF REFERENCE NUMBERS
