Description

Folding box for storing bulk material

The invention relates to a carton for storing bulk material.

From WO 93/13 995 A1 a folding box for storing bulk material is known, which comprises a Faltschachtelkörper. At this Faltschachtelkörper a closure is provided which opens and closes an opening in the Faltschachtelkörper. This closure is designed as a click closure and has four pressure surfaces, which are pressed in the direction of the interior of the Faltschachtelkörpers to convert the click closure in an open position. After releasing the actuating force on the pressure surfaces, the closure closes.

From DE 93 11 178 U a foldable cardboard packaging box is known. This carton has a deflectable spout to release an opening for dispensing the bulk material.

From DE 20 2016 101 728 U1 a resealable carton for storing free-flowing material is known. This carton has a closure which is provided in a corner region of the carton. This closure is connected by a hinge fold with a side wall of the carton. To open the closure, the latter comprises at least one first projection on a pivotable cover, which engages behind at least one further projection on a side wall of the folding box in a closed position.

The invention has for its object to propose a carton, which is designed re-closable in a simple manner and allows easy operation to open the carton and an independent closing this opening of the carton.

This object is achieved by a carton, in which a closure for an opening in a carton body is designed as a click closure, which has at least one pressure point and a lid associated therewith, which transfers the lid from a closed position to an open position upon actuation of the pressure point and after releasing an actuating force to this pressure point, the lid automatically returns to the closed position. The closure extends partially along a folding edge between two adjacent side walls of the folding box body and partially in each case in the side walls of the folded box body at least partially. In two further side walls of Faltschachtelkörpers the opening is provided, which are covered by the closure having the side walls. By means of this click closure, it is possible to apply only an opening pressure to the folding box for opening the folding box for dispensing the bulk material stored therein, and after the desired amount of bulk material has been dispensed, the closure is automatically transferred to the closed position by releasing the pressure point. Such a click fastener preferably makes it possible to unfold the closure when the pressure point is actuated, wherein an end position of the pressure point in the folding box is not self-holding, so that after releasing the opening force to the pressure point, the independent return to a starting position and thus the cover can be transferred to the closed position is. In this closed position, the lid is preferably provided self-holding.

Due to this arrangement of the closure, which extends along a folding edge between two side walls and projects at least partially into the two side walls, the restoring force can be generated, which after releasing the actuating force on the pressure point, in particular the fold, an independent reset of the closure in the closing position allows.

It is preferably provided that the cover of the closure covers the opening in the further side walls and laterally adjacent to the opening side wall portions of these other side walls. This has the advantage that the hinged lid can not be pressed into the interior of Faltschachtelkörpers in case of incorrect operation. In addition, a safe and complete closing of an opening edge of the opening can be made possible by this cover. For this purpose, the contour of the opening deviates from the course of an outer edge of the lid. In particular, the outer contour of the lid is sheet-shaped larger than the underlying portion of the opening formed. As a result, an overlap region is formed, in which the cover covers a side wall section adjoining the opening.

Advantageously, the closure is drop-shaped and extends symmetrically to the folded edge of Faltschachtelkörpers. As a result, the opening force and the restoring force for actuating the closure act to the same extent.

The pressure point is preferably formed by the folded edge, which extends along the closure. As a result, a defined point of attack is formed and allows easy operation.

Furthermore, it is preferably provided that adjacent to the pressure point two pressure surfaces are formed, which extend into the side walls, wherein the pressure surfaces are connected by a folding line, in particular perforation, with the lid. This allows a simple articulation of the lid to the pressure surfaces and the control of an opening movement for the closure.

Furthermore, it is preferably provided that the pressure surfaces adjoining pressure surfaces are limited to the side walls by a hinge line. This hinge line is preferably formed by a stamping line, in which the wall thickness of the side wall is tapered.

Advantageously, it is provided that the pressure surfaces, starting from a drop tip, each have two hinge lines extending into the side wall. When the pressure point on the folding edge is actuated, the folding edge is thereby pressed in the direction of the interior volume of the folding box and the adjacent pressure surfaces are pressed slightly along the hinge line in the direction of the interior volume. As a result, a slight bulbous erection of the side wall surfaces are generated, which provide after the release of the opening force for a return movement and thus a closing movement of the lid.

A further preferred embodiment of the invention provides that the lid is beak-shaped in an opening position. For example, the round, teardrop-shaped end of the closure is set up and preferably has this beak-shaped opening.

Advantageously, the lid of the closure can be transferred into an opening position to the folding edge, in which an angle of at least 15 ° is provided. This allows a sufficiently large volume of expenditure for the output of the bulk material.

Furthermore, it is preferably provided that, starting from the fold edge, the hinge line is delimited by the folding line and, following the drop shape of the closure, a cutting line is provided between the cover and the respective side wall. This allows the production of the closure in a blank in a simple manner.

Advantageously, the blank for the carton comprises two further side walls in which the opening is provided, which are covered by the side walls receiving the closure after formation of the Faltschachtelkörpers and bonded thereto. It is preferably provided that the closure is aligned congruent to the opening. This allows the lid of the closure to be lifted relative to the opening and thus this opening can be released for dispensing the bulk material.

The opening in the side walls extends along the folded edge of the two side walls and preferably has a profile of the opening edge starting from the folding edge, which corresponds to the hinge line of the pressure surface. This allows the pressure point and the pressure surfaces laterally adjacent to move toward the interior volume of the carton body. The hinge lines adjacent the opening edges of the opening form an abutment. As a result, the adjacent side walls to the folding edge, in particular by the two-ply training, stiffened, however, the single-layer pressure surfaces can be actuated in a simple manner.

An opening edge of the opening which is closed by the cover preferably has a circular contour starting from the folded edge. This allows an enlargement of the opening on the one hand and a stiffening of the opening contour in the region of the folding edge.

Furthermore, it is preferably provided that the closure in the original state of the folding box between the lid and the adjacent side wall has at least one connecting web, which is separable by operating the closure. As a result, a tamper-evident closure can be created.

Furthermore, it can preferably be provided that the closure in the original state of the folding box in a region covering the opening with the or the adjacent side walls has a releasable adhesive bond. Also by this a quality closure can be created. Also, a combination of the two aforementioned quality seals can be provided.

It is preferably provided that the folding box body is formed with the resealable closure of a single blank of a sheet-like material. This allows for easy manufacture and subsequent rapid formation of the carton body.

The invention and further advantageous embodiments and developments thereof are described in more detail below with reference to the examples shown in the drawings and explained. The features to be taken from the description and the drawings can be applied individually according to the invention individually or in combination in any combination. Show it:

FIG. 3 shows a further perspective view of the folding box with an opened closure.

1 shows a schematic view of a blank 12 of a folding box 11 shown in FIGS. 2 and 3. This blank 12 has side walls 14, 15, 16, 17, 18, 19. On the side walls 14, 15, 16, 17 bottom tabs 21, 22, 23, 24 and cover tabs 25, 26, 27, 28 are provided. The side walls 18, 19 are formed without bottom tab and lid flap, for example.

The connection of the bottom flaps 21, 22, 23, 24 and cover flaps 25, 26, 27, 28 to the side walls 14, 15, 16, 17 and the connection of the side walls 14, 15, 16, 17, 18, 19 to each other by folding lines 31, which are shown in the blank 12 dashed lines.

In order to form a folding box body 33 of the folding box 11 according to FIGS. 2 and 3, the side walls 14, 15, 16, 17 are folded along the folding line 31 and the respective bottom and cover tabs 21, 22, 23, 24, 25, 26, 27, 28 folded toward each other and preferably glued together.

The side walls 18, 19 are preferably positioned congruent with the side walls 14, 15 and along at least one adhesive surface 35, 36 provided on the side walls 14, 15 or on the side walls 18, 19 or on all side walls 14, 15, 18, 19 are glued together.

The blank 12 comprises an opening 41, which preferably extends symmetrically to the fold line 31 in the side walls 14, 15. The contour of the opening 41 is adapted to the contour of a closure 44 which is introduced in the side walls 18, 19. This closure 44 consists of at least one pressure point 46, which lies after folding of the side walls 18, 19 by, for example, 90 ° on a folded edge 47 of the folded box body 33. This pressure point 46 may be part of the folded edge 47 between two side walls 18, 19. This pressure point 46 may also be an actuating point in the form of a surface or a trough. As a result, a simple actuation of the closure with a finger can be made possible. Adjacent to this pressure point 46 extending pressure surfaces 48, 49. At these pressure surfaces 48, 49 then a lid 51 is provided. The pressure surfaces 48, 49 are limited by a folding line 52 to the lid 51. Furthermore, the pressure surfaces 48, 49 are limited by a hinge line 54 to the side walls 18, 19. The folding line 52 is preferably formed as a perforation line. The hinge line 54 is preferably formed as a stamping line.

The closure 44 is drop-shaped. Starting from a tip 56 of the drop, which preferably lies on the folded edge 47, the hinge line 54 extends on both sides into the side wall 18, 19, wherein the hinge line 54 terminates at a crossing point 58 with the respective folding line 52. The folding line 52 extends symmetrically to the folded edge 47, wherein the folding lines 52 are aligned in a V-shape to each other to the folding edge 47. These include an angle of less than 90 ° towards the lid 51. Starting from the intersection point 58 of the hinge lines 54 and the folding lines 52, a cutting line 60 is provided, which extends along the teardrop shape. By the section line 60, the lid 51 is separated from the side wall portions 18, 19.

It can preferably be provided that between the cover 51 and the side wall 18 and / or 19, a connecting web 62 is provided. This connecting web 62 may form a tamper-evident closure. The connecting web 62 can be separated by actuating the closure 44.

The opening 41 has, starting from the folding line 31 or the folding edge 47 of the folding box body 33, an opening edge 64 which corresponds to the course of the hinge line 54 of the closure 44. This opening edge 64 preferably extends at least slightly beyond the crossing point 58 of the closure 44. Subsequently, the opening edge 64 tapers in order to preferably transition into a circular contour 66 in the region of the folded edge 47. The taper of the opening edge 64 between the crossing point 58 and the preferably circular contour 66 is steeper than an outer contour of the lid 51, which is formed by the sectional contour 62. As a result, adjacent to the opening edge 64 of the opening 41 side wall sections 68 are formed, which are covered by the cover 51. The lid 51 abuts against these side wall sections 68. These side wall portions 68 may be arcuate, crescent or the like. These side wall portions 68 form an abutment for the cover 51, so that it can not be pressed into the interior of the folding box body 32. It is preferably provided that adhesive dots are provided on the side wall sections 68, so that the cover 51 is held in a closed position by means of the adhesive connection at least during delivery. These adhesive dots can also be provided with a releasable adhesive, in which the lid 51 can be solved for the output of a bulk material and is then held again in a secure closed position.

The blank 12 for forming the folding box body 33 is preferably formed in one piece. The blank 12 may be made of cardboard, paper or a paper / plastic composite material. Also, such a sheet-like material may be provided with an inner coating, in particular to create a hygienic packaging when taking food.

FIG. 2 shows the folding box 11 formed from a blank 12. The closure 44 of the carton 11 is closed.

FIG. 3 shows a perspective view of the folding box 11 with an opened closure 44.

By actuating the pressure point 46, the folding edge 47 is pressed in the direction of the inner volume of the folding carton body 33. The pressure surfaces 48 pivot along the hinge line 54 inwards. The lid 51 can be placed along the folding line 52, as shown in Figure 3. This erected position of the closure 44 is maintained as long as an opening pressure on the pressure point 46 acts. The side walls 18, 19 are bulged. This causes a reset effect after releasing the opening force on the pressure point 46. As a result, the lid 51 automatically returns to a closed position, as shown in Figure 3. The arrangement of the closure 44 along the folded edge 47 of this snap closure can be formed. In an open position, the lid 51 of the closure 44 is beaked.

Due to the contour of the opening 41 in the side walls 14, 15, the pressure surfaces 48 in the side walls 18, 19 on the one hand to the internal volume of the carton body 33 are transferred, but these are on the other hand thereby also automatically reset to the starting position. In the initial position of the pressure surfaces 48, the lid 51 is held in a closed position. This prevents an undesired discharge of the bulk material into the folding box body 33.

In the carton 11 various types of bulk materials can be included, such as food, especially chewing gum or dragees, or consumables in granular or powder form.
