Description

The invention relates to a carton for confectionery, snacks, drinks or the like.

For the packaging of confectionery cardboard boxes are known in a variety of designs. For example, there are cuboid or cup-shaped cartons. Known folding boxes are usually filled by an opening at the top, which is closed by means of a lid. The lid consists for example of several top wall sections, which can be folded into the opening and locked or glued together. The carton is formed for example of an uncoated or plastic-coated cardboard, which is liquid-impermeable. In many cases, the goods are placed directly in the carton. It is also known to pack the goods in a plastic bag hermetically sealed and insert the bag in the carton to improve the durability of the product.

The invention has for its object to provide a simple and safe to close and open folding box for confectionery, snacks, drinks or the like.

The object is achieved by a folding box with the features of claim 1. Advantageous embodiments of the carton are given in subclaims.

• einen Becher mit einer seitlichen Becherwand, einer Bodenwand und einer mehrere Deckwandabschnitte aufweisenden Deckwand, wobei die seitliche Becherwand am oberen Rand jeweils zwischen zwei Ecken einen oberen Randabschnitt aufweist,
• die Deckwandabschnitte jeweils über eine obere Faltlinie an einen oberen Randabschnitt angelenkt und um die obere Faltlinie in oder über eine von den oberen Randabschnitten umgrenzte obere Öffnung des Bechers faltbar sind,
• wobei mindestens zwei Deckwandabschnitte oder ein Deckwandabschnitt und die seitliche Becherwand Verrieglungselemente aufweisen, welche die beiden Deckwandabschnitte in einer die obere Öffnung versperrenden Stellung miteinander verriegeln.

The carton according to the invention for confectionery, snacks, drinks or the like comprises:

• a cup with a lateral cup wall, a bottom wall and a cover wall sections having a plurality of top wall, wherein the lateral cup wall at the upper edge in each case between two corners has an upper edge portion,
• the top wall sections are each hinged to an upper edge section via an upper fold line and are foldable about the upper fold line into or over an upper opening of the cup bounded by the upper edge sections,
• wherein at least two top wall sections or a top wall section and the side cup wall have Verrieglungselemente which lock the two top wall sections in a blocking the top opening position with each other.

The carton according to the invention can be filled and emptied through the upper opening of the cup. Here, the top wall sections are folded around the upper fold lines to the outside. The carton is easy to close by the top wall sections are folded or folded over each other. In the folded or folded-over layer, at least two cover wall sections or a top wall section and the side cup wall can be easily locked together by locking locking elements of these parts of the folding box together. The locking elements may be formed so that the locking of the locking elements in the folding or folding over of the top wall sections is made or they may be configured so that the lock is made only after the top wall sections have been folded or folded over one another. When at least one top wall portion is locked with a locking element, it can restrain underlying top wall sections in a position in which they also block the upper opening. According to one embodiment of the invention, more than two cover wall sections on locking elements which lock in a blocking the upper opening position with each other. In particular, it is possible that all cover wall sections have such locking elements. To open the top wall, the locking elements can be unlocked and the top wall sections are unfolded. Depending on the structural design of the locking elements, their unlocking can be done simultaneously with the unfolding of the top wall sections or prior to unfolding the top wall sections.

Folding cartons in the form of a cup and thus a one-piece executable, sealable top wall was created for the first time with the invention.

An embodiment of the invention relates to a carton according to claim 1, wherein the two top wall sections which are articulated via two parallel upper fold lines to two opposing upper edge portions, each having a parallel to the upper fold lines slot, wherein the slots in the two top wall sections of extend lateral edges of the top wall portions in different directions so far in the two top wall sections that at least the ends of the two slots overlap each other when the two top wall sections are folded over each other, and in the outer fold lines in the two top wall portions of overlap points starting at where the two slots overlap each other when the top wall sections are folded over each other, each extending to the outer edges of the top wall sections, so that the slots and the other fold lines ei in each case in a top wall section ne locking flap limit, which is foldable around the outer fold line to the outside of the respective top wall portion in an unlocking position in which the top wall sections one above the other are foldable and foldable after folding over the top wall portions to the outside of the other top wall portion out in a locking position in which the locking flaps engage behind each other with lateral edges of the slots.

In this embodiment, the locking elements are formed by the locking flaps and the adjacent slots of two top wall sections. The carton is easy to close by folding each locking flap around the outer fold line to the outside of the cover wall portion connected to it and the top wall sections are folded or folded over each other. In the folded or folded-over position, the top wall sections are easily locked together by folding each locking flap around the outside fold line to the outside of the other top wall section. As a result, the locking flaps are brought into a locking position, in the mutually facing lateral edges of the slots abut each other and prevent opening of the top wall. To open the top wall, each locking flap can be folded around the outer fold line to the outside of the top wall section connected thereto, and then the top wall sections are folded outwardly about the top fold lines. Even a reclosure of the carton is easily possible. Another advantage is that the top wall in the closed state has a look reminiscent of a loop. The loop shape is formed by slightly elevating the top wall sections with respect to the top opening in the locking position and raising the locking flaps and the portions of the top wall sections disposed on the opposite side of the outer folding lines furthest with respect to the top opening. Furthermore, several Folding cartons with locked top wall sections can be stacked on top of each other to store them in a space-saving manner.

According to one embodiment of the invention, the slots each have a slot width of 1 mm to 5 mm, preferably from 2 mm to 4 mm, further preferably 3 mm. With these dimensions, closable and openable folding boxes are achieved in a particularly simple and secure manner.

According to a further embodiment, each slot extends only over half the width of the respective top wall portion. As a result, a particularly secure entanglement of the locking flaps is achieved with each other, in which abut the ends of the slots to each other.

According to a further embodiment, each outer fold line extends in the respective top wall section perpendicular to the upper fold line, via which the respective top wall section is articulated to the upper edge section of the cup. As a result, a secure locking is achieved with easy locking and unlocking. In principle, it is also possible that the outer fold line includes an acute or obtuse angle with the upper fold line.

According to a further embodiment, the lateral edges of the cover wall sections are curved arcuately outwardly at least outside the slots. As a result, the loop shape is more closely approximated by the closed top wall.

According to a further embodiment, the outer edges of each top wall portion between the outer end of the outer fold line and each curved side edge of the top wall portion to the outside. As a result, the loop shape is more closely approximated by the closed one.

According to a further embodiment, the distance of the outer edge of each cover wall portion from the upper fold line, via which the respective top wall section is articulated to the upper edge section, increases from the outer end of the outer fold line to the lateral edges of the respective cover wall section. This further improves the approach to the appearance of a loop through the closed top wall.

According to one embodiment of the invention, a cover wall portion has a locking element in the form of a pivotable tongue and the side cup wall on a locking element in the form of a plug-in slot. The tongue is preferably integrated in a connected via a fold line with the top wall portion locking tab. For this purpose, the locking tab preferably has a broken fold line which is parallel to the fold line, over which the locking tab is connected to the top wall portion. In the interruption of the broken fold line the tongue is punched out in the locking tab on the side of the broken fold line, which faces the fold line, via which the locking tab is hinged to the top wall portion. Such a carton is in Fig. 15 and 19 shown.

After closing the top wall portion with the hinged locking tab, the locking tab is folded against the side cup wall and swung the tongue in the slot. In the locked position, the tongue fixes the locking tab on the side cup wall. In the locked position of the top wall portion holds the underlying top wall sections in the closed position. To unlock the tongue is folded down, so that the locking tab can be folded away from the cup wall and the top wall section can be opened.

According to one embodiment of the invention, the locking elements comprise a tongue on a top wall portion and a slot on another cover wall portion. Preferably, the locking tongue is formed in the manner described above in a locking tab, which is connected via a fold line with a top wall portion. The top wall portion with the hinged locking tab in which the tongue is formed, and the top wall portion with the insertion slot formed therein are zusammenschwenkbar. In the pivoted-together position, the locking tab can be folded over the cover wall section with the insertion slot, so that the insertion tongue can be swiveled into the insertion slot. When the two cover wall sections are locked together, they can fix under cover wall sections arranged in the closed position over the opening of the cup. To open the tongue is in turn pivoted down so that they can get out of the slot and the locking tab is wegschwenkbar from the top wall portion with the slot. Thereafter, all top wall sections are swung open. Such a carton is in Fig. 18 shown.

According to a further embodiment, a cover wall section has a plug-in tab. When swiveling the cover wall section, the insertion flap can be clamped behind an edge section, which lies opposite the edge section to which the cover wall section with the insertion flap is applied. For secure fixing of the top wall portion, preferably, the edge portion has a further top wall portion which is hineininfaltbar into the cup and behind the Clamps edge portion clamped insertion tab. Such a carton is in Fig. 17 shown.

According to a further embodiment, the locking elements are formed so that two cover wall sections next to the upper fold lines, via which they are hinged to the side cup wall, punched out. These are top wall sections, which are hinged to opposite edge portions of the side cup wall. The punch-outs can be arranged immediately adjacent to the fold lines over which the top wall sections are connected to the side cup wall. But they can also be arranged at a distance from the fold lines. Another top wall section has at its two lateral edges on folding lines hinged tabs. The top wall sections with the cutouts are foldable into the upper opening of the cup and the top wall section is foldable with the lateral tabs over the top wall sections. In this case, the lateral tabs are foldable down and inserted into the punched, whereby said cover wall sections are locked together. To open the carton is moved in the reverse manner. Such a carton is in Fig. 17 shown.

According to a further embodiment, two cover wall sections, which are hinged by fold lines to opposite edge portions of the lateral cup wall, have locking elements. In a top wall section, the locking element is a tongue on the outer edge of the top wall section. In the other top wall section, the locking element is a plug-in slot, which is aligned approximately parallel to the fold line, via which the top wall section is articulated to the side cup wall. When folding the two top wall sections one above the other, these are by pinching the tongue in the slot locked together and unlocked in the reverse manner. Such a carton is also in Fig. 18 shown.

According to a further embodiment, two cover wall sections, which are articulated on opposite edge sections of the lateral container wall, at their outer ends hinged on folding lines tabs on. At two further edge portions of the lateral container wall more cover wall sections are hinged on fold lines. In the two other top wall sections are plug-in slots, which are aligned perpendicular to the fold lines over which the two other top wall sections are hinged to the side cup wall.

The top wall sections with the tabs are pivotable in or over the opening and the tabs in vertical alignment can be applied to each other. Furthermore, the two further cover wall sections are übereinanderfaltbar, so that the insertion slots overlap each other. The tabs are inserted into the slots and fold away from each other, whereby all cover wall sections are locked together. The opening is done in reverse order. Such a carton is in the Figures 20 . 21 and 22 shown. Furthermore, it is possible first to fold the cover wall sections with the insertion slots over the opening and then to fold the cover wall sections with the insertion tongues over them and insert them with the insertion tongues down into the insertion slots. The tabs then engage in the carton.

According to a further embodiment, the carton has a further top wall portion which is connected via a fold line with an edge portion of the side cup wall, which is arranged opposite the edge portion, hinged to the top wall portion with the two side tabs is. The further top wall section has further plug-in slots. The further top wall section can be folded over the upper opening, so that each of its plug-in slots is arranged above a slot of an adjacent top wall section. The top wall section with the lateral tabs can be locked with each tongue in two mutually overlapping tabs. Such a carton is also in Fig. 19 shown.

According to a further embodiment, the locking elements are formed so that a plurality of cover wall sections are foldable rosette-like in a curved state in which they partially cover each other and mutually secure in a locking position. Such a carton is in Fig. 23 shown.

According to a further embodiment, the carton has further top wall sections, which are foldable as dust flaps in the upper container opening and over which the top wall sections are foldable, which have the locking flaps. As a result, the closure of the carton is further improved by the top wall.

According to a further embodiment, the further cover wall sections do not overlap each other when they are folded into the cup opening. This simplifies the folding process and saves material.

According to a further embodiment, the cup widens from bottom to top. This allows the nesting of similar cartons to store them before filling goods to save space.

According to a further embodiment, the carton has a cup which widens from the bottom upwards and which is frustoconical in a lower cup portion and has in an upper cup portion between corners wall sections each having an opening towards the outside which reduces to the upper edge portion. As a result, a particularly pleasing and haptic external shape of the cup is achieved.

According to a further embodiment, the corners are formed by longitudinal fold lines which extend in the longitudinal direction on the circumference of the cup. In a cup with a frusto-conical lower cup portion, the fold lines in the side cup wall terminate at a distance from the bottom wall. In the case of a parallelepiped carton, the longitudinal fold lines end at the lower edge of the lateral cup wall.

According to a further embodiment, the lateral cup wall on a longitudinal fold line on a side edge tab and a top wall portion at an upper fold line in continuation of the longitudinal fold line on an upper edge tab and is an adjacent edge region of the side cup wall with the side edge tab and an adjacent edge region of the top wall portion connected to the upper side edge tab. This is particularly advantageous for the production of folding cartons of blanks foldable flat material.

According to a further embodiment, at least one strip-shaped outer bottom edge tab is folded inwards at the lower edge of the cup around a lower fold line and the bottom wall has a disk with at least one circumferentially downwardly projecting inner bottom edge tab which is folded between the side cup wall and the inwardly folded one Bottom edge tab is arranged. As a result, a particularly tight connection of the bottom wall is achieved with the side cup wall. This embodiment is particularly advantageous for folding boxes with a conical lower cup section with a circular disk-shaped bottom wall. But it also comes in cartons with polygonal bottom wall into consideration, especially in cuboid cartons. In cartons with polygonal bottom wall, the bottom wall is preferably formed by bottom wall sections, which are folded over fold lines at the bottom of the side cup wall in a lower opening of the cup and connected to each other.

Furthermore, the object is achieved by a folding box with the features of claim 13. Advantageous embodiments of the carton are given in subclaims.

In the present application, the terms "top" and "bottom" and "horizontal" and "vertical" refer to an orientation of the carton with a horizontal bottom wall and the top wall above the bottom wall.

According to Fig. 1 For example, a blank 1 has a lateral cup wall 2 with arcuately curved lower edge 3 and an outer bottom edge tab 5 connected thereto via a lower fold line 4.

In the side cup wall 2, four longitudinal fold lines 6, 7, 8, 9, which are each aligned perpendicular to the lower edge 3 extend. The lateral fold lines extend approximately from the middle of the lateral cup wall and extend to the upper edge of the lateral cup wall. The upper edge 10 of the lateral cup wall 2 has in each case between the ends of two adjacent lateral fold lines 6, 7, 8, 9 a rectilinear upper edge portion 11, 12, 13, 14, wherein the edge portion 11 left and right on the blank 1 has separate parts ,

At each upper edge portion 11, 12, 13, 14, a top wall portion 19, 20, 21, 22 is articulated via an upper fold line 15, 16, 17, 18, wherein the Top wall portion 19 has left and right on the blank 1 separate parts. To the upper edge portions 12, 14 cover wall portions 20, 22 are hinged, the slots 23, 24 which extend parallel to the upper fold lines 16, 18. Each slot 23, 24 extends from a side edge of the top wall portion 20, 22 and terminates in the middle of the top wall portion 20. From the end of each slot 23, 24 extends an outer fold line 25, 26 to the outer edge 27, 28 of Top wall portion 20, 22. The outer fold line 25, 26 is formed perpendicular to the upper fold line 16, 18, via which the respective top wall portion 20, 22 is hinged to the side cup wall 2.

The lateral edges 29, 30, 31, 32 of the two cover wall portions 20, 22 are substantially rectilinear between the upper fold line 16, 18 and an axis defined by the slot 23, 24. Outside the axis defined by the slot 23, 24 they are arcuately curved outward.

The outer edges 27, 28 of each top panel section 20, 22 are arched outwardly between the outer end of the outer fold line 25, 26 and each side edge 29, 30, 31, 32 of the top panel section 20, 22. The distance of the outer edge 27, 28 of each top wall portion 20, 22 from the upper fold line 16, 18 increases from the outer end of the outer fold line 25, 26, starting at the lateral edges 29, 30, 31, 32 of the respective top wall portion 20, 22.

About the upper fold lines 15, 17 more top wall sections 19, 21 are articulated to the side container wall 2. The further top wall section 21 is formed in one piece.

The further top wall section 19 is formed by two parts left and right on the blank 1.

The further cover wall sections 19, 21 are substantially rectangular. They form dust flaps. The outer edge 33, 34 of the further cover wall sections 19, 21 is located less far from the upper fold lines 15, 17 than in the cover wall sections 20, 22. In the example, the distance of the outer edge 33, 34 of the other top wall portions 19, 21 from the upper fold line 15, 17 is slightly less than the distance of the slots 23, 24 from the upper fold lines 16, 18th

The blank 1 is formed by bending the lower portion of the lateral cup wall 2 and folding the upper portion of the lateral cup wall 2 about the lateral fold lines 6, 7, 8, 9 and by gluing the lateral edge portions 34, 35 of the side cup wall 2 and possibly the Parts of the other top wall sections 19 and the lower bottom edge tab 5 brought in cup form. The cup 2.1 extends slightly from bottom to top (see. Fig. 3 ).

The further blank 36 comprises a circular bottom wall 37 having a plurality of inner bottom edge tabs 38 on the circumference 39, which have the shape of trapezoidal tongues. To prefabricate the carton, the inner bottom edge tabs 38 are folded away by fold lines 40 vertically from the bottom wall 37 and the further blank 36 is inserted into the lower end of the cup-shaped erected blank 1. Thereafter, the outer bottom edge tab 5 is folded inwardly and sealed or glued to the inner bottom edge tabs 38.

A large number of prefabricated folding boxes can be stored and transported in the manner of a bar.

Fig. 3 shows the prefabricated carton 41 when folding the other top wall sections 19, 21 in an upper opening 42 between the upper edge portions 11, 12, 13, 14, as happens after filling the carton with goods.

According to Fig. 4 Subsequently, the top wall sections 20, 22 are folded toward the upper opening 42.

The slots 23, 24 and the outer fold lines 25, 26 define a locking flap 43, 44 in each top wall section 20, 22. According to Fig. 5 For locking, the locking flaps 43, 44 are folded outwardly towards the outside of the respective top wall section 20, 22 to which they are connected. As a result, the top wall sections 20, 22 can be folded past one another such that the one cover wall section 20 rests partially (with the region adjacent to the locking flap 43) on the other top wall section 22 and the other top wall section 22 partially (with the region adjacent to the locking flap 44) a top wall portion 20 rests. Thereafter, the locking flaps 43, 44 are folded back, as in Fig. 6 shown. In this situation, the locking flaps 43, 44 with side edges 45, 46, which define the slots 23, 24, abut each other. As a result, the top wall sections 20, 22 are secured in the locked position.

For the removal of goods, the cover wall sections are opened in the reverse manner. First, the locking flaps43, 44 are unlocked, then the top wall sections 20, 22 folded outwards and finally the other cover wall sections 19, 21 folded outwards. This will make the top opening 42 open for the removal of goods. The folding box 41 is resealable.

The blanks 1, 36 may be formed from coated or uncoated cardboard.

According to Fig. 7 it is possible to seal the above-described folding box 41 by means of a sealing foil 47. In this case, the folding box 41 is preferably formed from a cardboard coated at least on the inside with plastic. This also favors the tight joining of the blanks 1 and 36 by sealing the bottom edge tabs 5, 38 together.
