Description

[0001] The invention relates to a one-piece folding cut for a container, which

5 serves to accommodate bulk products such as detergent or cleaning agent. The invention also relates to a package, which is based on a folding cut. [0002] From US 5,363,981 a foldable cut of this type of cardboard is known, having four elements arranged adjacent to each other,

10 separated in each case by fold lines, which form in the folded state a front side, a first front side, a rear side and a second front side of the package. Several bottom tabs are connected at a lower edge of the elements, from which a container can be manufactured. The bottom tabs are connected in this case by means of fold lines with the elements. For the rest, the cut

Folding document of US 5,363,981 has several cover tabs, which are connected by means of fold lines at an upper edge of the elements and from which at least a part of an articulated lid element of the package can be manufactured . [0003] The folding cut also has a neck. The neck is joined by means

20 of a fold line with the rear side and comprises a first front side part, a front side part and a second front side part. The three parts of the neck are separated in this case from each other by means of fold lines, so that these fold lines extend parallel, respectively, to the fold line, which connects the neck with the back side, and to

25 the fold lines, which separate the front side and the rear side and the first and the second front side from each other. In this way, the front side, the first front side, the rear side, the second front side as well as the three parts of the neck are arranged adjacent to each other, which leads to a large width of the folding cut. The foldable cut folds during the manufacture of the container now such

30 so that the neck is supported, when the package is folded, on the front side and the first and the second front side rests on an inner side and is covered at least by the cover element in a closed state. By means of the neck in collaboration with the lid element, the container can be closed tightly, so that the detergent in the package is well shielded from the surroundings.

[0004] To fold it into a parallelepiped shaped container, the flat folding cut is driven to a folding machine. In this case, the foldable cut is inserted transversely into the machine, so that the total width of the elements placed adjacent to each other and of the neck portions predetermines the necessary width of the machine. Therefore, the machines must be made

5 comparatively wide, which can be an inconvenience in the case of a limited space offer. [0005] When the folding cut according to US 5,363,981 is not inserted exactly into the machine, so that the folding cut is not exactly aligned at right angles to the transport direction of the

10 machine, due to the large width of the folding cut, displacement can occur, by virtue of which it is no longer possible to correctly fold the folding cut to the desired accuracy. [0006] Therefore, the invention has the task of preparing a folding cut, which can be easily cut and folded well and without problems with the machine

[0007] The task on which the invention is based is solved by means of a collapsible cut with the features of claim 1. Preferred embodiments can be deduced from dependent claims 2 to 14. [0008] According with the invention it is provided that in the deployed state of the folding cut, that is, when the folding cut is flat, the neck is arranged

20 above the top edge of the lid tabs. In this way, the neck is not connected laterally in the adjacent arranged elements (front side, first and second front side, rear side), but is located above these elements. This reduces the width of the folding cut, which is now composed only, apart from possible adhesive tabs, of the width of the front side,

25 on the back side, the first and the second front side. Through the arrangement according to the invention of the neck above the elements a compact folding cut is created, which can be processed easily on machines with smaller width. [0009] In the neck, preferably the front side part, may be arranged

At least one closing flange and an opposite piece, so that when the package is folded, the opposite piece and the closing flange collaborate with the purpose of a removable fixing of the lid element. The opposite part can be properly fixed to the cover element for this purpose, for example by gluing. [0010] In a preferred embodiment, the closure tab and the part

Opposite 35 form a bridge of material, which connects the neck with one of the tabs

of the lid. In this way, the neck can be connected through this bridge of material and, in a corresponding embodiment, also through the first and second rib with various flanges of the lid. Preferably in this case, the closure flange is connected through a fold line with a front 5 side of the neck. On one side of the closing flange, which is far from the front side part, the opposite piece can be connected through a weakening line. In the originally unopened state of the container, the opposite part and the closure tab are connected to each other by means of this line of weakening. If the container is now opened, unfolding the lid element afterwards

10 to tear the strip element, the opposite piece and the closure tab are separated from each other. They support each other again when the cover element is closed. [0011] The fold line, which connects the neck with at least one of the elements and / or with at least one of the cover tabs, can be extended perpendicularly to the fold lines that separate the elements. With

In preference, the neck is arranged on the front side, on the first front side and on the second front bark. In this way, the neck can be connected along the fold line, which connects it with at least one of the elements and / or with at least one of the cover tabs, to be turned 180 degrees or folded, so that the neck rests on the front side or on the first and the

20 second front side. [0012] Preferably, the neck has a front side part, a first front side part and a second front side part, so that the first front side part and the second front side part are separated, respectively, by means of lines of front side fold. When

25 the container is folded, the first front side part rests on the first front side, the front side part rests on the front side and the second front side part of the neck rests on the second front side. By means of gluing points or gluing lines, the individual parts of the collar can be fixed on the respective support side of the package.

[0013] In a preferred embodiment, the neck has a first rib and a second rib, so that the first rib connects the first frontal lateral part of the neck with a flange of the lid of the first frontal side and the second rib connect the second front side of the neck with a tab on the cover of the second front side. The fold line, around the

35 which articulates the neck around 180 degrees for the manufacture of the container, extends along an upper edge of the tabs of the lid. A height of the first and the second rib corresponds in this case exactly or approximately to the height of the tabs of the cover of the first and the second front side. The height of a lid tab corresponds in this case to the

5 distance from the upper edge of the lid flange with respect to the upper edge of the elements, in which the respective flange of the lid is connected. [0014] In a preferred embodiment, a tear strip element extends transversely on the first and second front side as well as on the front side, so that, when the package is folded, after

10 tear the strip element, the lid element can be opened. The tear strip element defines in this case a first lower edge of the cover element. Since when the package is folded, the strip element has not yet been torn and in this way the container is in the original unopened state, the cover element and the shelf part of the container are connected to each other, of

15 so that no detergent or similar can be spilled. In addition, with the help of the pulling element, you can easily verify if the package is in the original unopened state. [0015] Between the front side part and at least one of the front side parts of the neck a recess of material may be provided. Through this

20 recess of material shortens the fold line between the front side part and the corresponding front side part, whereby the front side part and the front side part can be more easily articulated with each other. [0016] In a preferred embodiment, a neck edge, which forms an upper edge of the neck when the package is folded, is retracted in the area of the

25 fold line, which separates the front side part and one of the front side parts. This retraction of the upper edge leads, when during the manufacture of the package the front side part and the front side part are folded at a right angle, to a rounding of one of the upper corners of the hill that are then formed, through which the cover element must move during opening and

30 the closure. Through the rounding the lid element can be opened and closed more easily. [0017] The edge of the neck, which forms the upper edge of the neck when the package is bequeathed, may be retracted at least in a central area of the front side part in front of the areas of the front side parts. Through retraction

35 of the upper edge creates a distance between a lower side of the closed cover element and the neck, to improve the collaboration of the closing flange with the opposite piece arranged in the cover element. By means of an elastic flexion now possible of the cover element during closing, an elastic fit of the closing flange behind the opposite part is also ensured after use.

5 prolonged container. In addition, in an appropriate position of the closure flange and the opposite piece, an elastic flexion of the lid member can be adjusted in the closed state, so that the closure flange and the opposite piece are pressed against each other. [0018] In general, in this case, an interstitium remains between the upper edge of the

10 neck and the bottom side of the cover element. [0019] The width of one of the front side parts may correspond approximately to the width of the corresponding front side. In this way, the front side of the neck joins with an outer edge, when the package is folded, on the back side, so that, in order to seal it, it closes

15 a possible gap between the neck and the back side. [0020] One of the tabs of the lid may comprise a carrying handle. Another possibility to provide a container, which can be manufactured from the folding cut, with a transport handle, consists of providing suitable points and fixings on the front sides for the ends of a transport handle, which extends in a

20 arc from the first front side on the cover element to the second front side. By means of the fixation on the end side of the transport handle on the front sides, the container can be lifted without tilting through the transport handle also when the lid element is not closed or is inclined with respect to the rest of the container.

[0021] The invention also relates to a package for bulk products, such as detergent, which is based on a collapsible cut according to one of claims 1 to 14. It should be noted that the package can also be based on a folding cut and on a neck separated from the foldable cut. In this case, the folding cut comprises, while it is a parallelogram-shaped container,

30 a rear side, a front side, a first front side and a second front side as well as several tabs on the bottom and lid. The neck preferably comprises a first front side part, a front side part and a second front side part. The neck and the foldable cut can be in this case of the same material and only join together during the manufacture of the container.

[0022] With the help of the embodiments shown in the figures,

explains the invention in detail. In this case: Figure 1 shows a package according to the invention. Figure 2 shows a folding section according to the invention; and Figure 3 shows the folding section of Figure 2 with a neck turned 180

5 degrees [0023] A container according to the invention is shown in Figure 1, which is designated in its entirety as 1. The package 1 comprises a lid element 2, which is in Figure 1 in an open or unfolded state. The lid element 2 is articulably connected with the remaining part of the container 1 by means of a

10 bending edge 3. [0024] The package 1 can be manufactured from a foldable cut 4 of a piece, as shown in figures 2 and 3. The foldable cut 4 has four elements 5, 6, 7, 8 arranged adjacent to each other, which are separated from each other in each case by means of fold lines 9 extending parallel to each other. He

Element 5 forms, when the package is folded, a first front side, element 6 forms a front side, element 7 forms a second front side and element 8 forms a rear side of the container. [0025] On a longitudinal side of the rear side 8 (the corresponding element and the rear side are designated below with the same reference sign, this is

20 also applies similarly to the remaining elements) an adhesive flange 10 is provided, through which the rear side 8 can be connected with the first front side 5, so that the elements 5, 6, 7, 8 form a hose. [0026] At the bottom edge 11 of the elements 5, 6, 7, 8 four bottom tabs are connected, which are designated with the reference signs 5a to 8a and are used for

25 forming a bottom of the container 1. [0027] On the upper edge 12, tabs of the lid 5b to 8b are connected, which serve to form the element of the lid 2 (see Figure 1). A tear strip element 13 extends at a distance from the upper edge 12. Through the tearing of the strip element 13 the first front side 5 can be divided into

30 a lower part 5c and an upper part 5d. This is also conveniently applied to the front side 6 and the second front side 7, which can be divided by tearing the strip element 13 into a lower part 6c or 7c and an upper part 6d or 7d. As can be deduced from Figure 1, the upper parts 5d, 6d of the elements 5, 6, 7 form a marginal zone 14 of the

35 cover element 2. The lower parts 5c, 6c and 7c together with the rear side 8 form a storage part 15 of the container 1. [0028] As can be deduced from Figure 2, which shows the folding cut 4 in the unfolded or flat state, a neck 16 is provided above the upper edge 12, which comprises a first front side part 17, a side part

5 front 18 and a second front side part 19. Through the fold lines 20, which are understood in the same direction as the fold lines 9, the first front part 17 and the front side part 18 or the side part front 18 and the second front side part 19 are separated from each other. Through a first rib 21, the first front side part 17 of neck 16 is connected

10 with the lid tab 5b. A second rib 22 connects the second front part 19 of neck 16 with the tab of the cover 7b. Between the first rib 21 and the flange of the lid 6b as well as between the second rib 22 and the flange of the lid 7b are arranged two fold lines 23 aligned with each other. Around these fold lines 23 the neck 16 can be placed by means of fold

15 around 180 degrees on the elements 5, 6, 7. A neck 16 articulated around 180 degrees is shown in Figure 3. [0029] Between the flange of the cover 6b and the front side part 18 of the neck 16 are arranged the closing tab 24 and an opposite piece 25. The closing tab 24 and the opposite piece 25 are joined together by means of a line of

20 weakening 26. [0030] The closing flange 24 and the opposite piece 25 form a bridge of material between the front side part 18 of the neck 16 and the flange of the lid 6b. To bring the neck 16 to the position, as shown in Figure 3, the opposite piece 25 must be separated out of the lid tab 6b. More conveniently, so

Therefore, the opposite piece 25 and the flange of the lug 6b are only joined together by means of a line of weakening. [0031] The collaboration of the closing flange 24 and the opposite piece 25 for the purpose of a removable fixing of the cover element 2 can be described with the aid of Figure 1. As already mentioned above, Figure 1

30 shows container 1 with a lid element collapsed. To fold down the cover element 2 for the first time, the strip element 13 (see Figure 2) must be torn first, so that the first front side 5, the front side 6 and the second front side can be separated into the lower parts 5c, 6c, 7c and in the upper parts 5d, 6d, 7d respectively. When the cover element 2 now closes again, it covers

35 the neck 16 with its marginal zone 14, which is constituted by the parts 5d, 6d, 7d.

[0032] During the manufacture of the container 1, the opposite part 25 is fixed in the lid element 2, namely, in the marginal area 14 or, more precisely, in the upper part 6d of the front side 6. The opposite part 25 corresponds to the closure flange 24, which is arranged in the connecting edge 29 of the neck and is folded forward 5, so that, in the closed state of the container 1, it is between the front side part 18 of the neck 16 and the part 6d of the marginal zone 14 and joins at an upper edge 28 of the opposite piece 25. This joint causes, in the closed state of the container 1, an insurance of the cover element 2. When the element is pulled up of cover 2, conditioned by the flush connection, the closing flange 24 directed downwardly articulates and at the same time the front side part 18 of the neck 16 is pressed as well as the part 6d of the cover element 2 one out of the other. After overcoming a maximum resistance, then the cover element 2 elastically fits, so that the closure flange 24 jumps to an obliquely inclined downward position, as shown in Figure 1. The closure

15 of the cover element, during which the closing flange 24 jumps behind the connecting edge 29 of the opposite piece 25, implies an audible noise. [0033] To facilitate the closing and opening of the cover element, the upper ends 30, 31 of the neck 16 are rounded, so that the upper edge 28 is retracted in the respective zones. Also in the areas of the side parts

20 front 17, 19, the upper edge 28 of the neck is slightly retracted, so that the cover element 2 does not collide on the neck 16, without the opposite piece 25 fitting behind the closing flange 24. The recesses of the upper edge 28 of neck 16 described in this section are not shown in the folding cuts 4 of Figures 2 and

3.

[0034] In the manufacture of the folded container starting from the flat folding cut 4 according to figure 2, the neck 16 is first articulated about 180 degrees around the fold line 23, so that the neck 16 is placed flat on the elements 5, 6, 7. In this case, the closing flange 24 and the opposite piece 25 collide between the front side part 18 of the neck 16 and the front side 6, of

30 so that, unlike the representation of figure 3, the closing tab 24 and the opposite piece 25 point downwards. The opposite piece 25 is fixedly connected to the front side 6 or to the upper part 6d of the front side 6. The elements 5, 6, 7, 8 are folded in such a way that the flange is connected adhesive 10 rests on the first front side 5 so that it

35 extends in the longitudinal direction and can be glued. To form the bottom of the container 1, the bottom tabs 5a, 6a, 7a, 8a are folded around the bottom edge 11 around 90 degrees up and glued properly. The container 1 opened upwards can now be filled with detergent or the like. After filling, the tabs of the lid 5b, 6b, 7b, 8b are folded, glued and thus configured in a lid element 2. In this way the manufacturing of the container 1 is completed.
