Description

[0001] The invention relates to a packaging device according to the preamble of claim 1.

[0002] Packaging units that comprise an outer packaging and additionally feature one or more inner trays on or in which the individual products are arranged are widespread and well-known. Classic chocolate wrappers are a well-known packaging type in this case, in which, in multi-layer solutions, the individual trays rest on top of one another without any additional locking or latching devices.

[0003] It is a regular requirement for retailers and end consumers to design packaging units that contain multiple products in such a way that accidental falling out of such trays is avoided and that individual, unused products are still presented advantageously.

[0004] For example, US 2012 / 008578 A1 proposes providing an inner support and wrapping element that encloses the actual product on at least three sides and provides a locking element on each end face, into which a vertical (locking) tab pointing toward the bottom of the outer packaging can snap. While this secures the inner support and wrapping element, removal is so difficult that the outer packaging must be destroyed or completely unfolded, depending on the hardness and stiffness of the tab.

[0005] Another embodiment is disclosed in EP 2 778 086 A1, which proposes attaching an outwardly projecting (locking) tab to the end face of an inner support and wrapping element, extending the base surface. This tab projects upwards when the product or the support and wrapping element is inserted and snaps into place below a folding tab on the end face of the outer packaging. The support and wrapping element is thus securely held in its final position, analogous to US 2012 / 008578 A1, but removal is very complex.

[0006] The object of the present invention is therefore to provide a packaging unit which is improved in this regard.

[0007] This object is achieved by the packaging unit according to the features of claim 1; further advantageous embodiments are set out in the subclaims and / or mentioned below.

[0008] The packaging unit according to the invention comprises an outer box, at least one carrier element for receiving products, in particular at least two elongated products, such as at least two toothbrushes, formed from a carrier blank, wherein - the outer box comprises a base surface, at least two side surfaces and at least two end surfaces, and wherein at least one folding flap is arranged on each end surface for at least partial contact with the end surface, wherein at least one folding flap has at least one contact edge, and wherein - the support element has two end faces, two longitudinal edges, a roof section and at least one base section, and wherein at least one locking tab is arranged on each end face, and wherein - the locking tabs of the carrier element can be locked onto the contact edges of the folding flap in such a way that they can be fixed in a low position (within the outer box), and wherein - a folding flap of an end face has at least two opposing contact edges or - two opposing folding tabs on one end face each have at least one (jointly opposing) contact edge. In this case, the (horizontally) opposing contact edges have a (horizontal) distance that increases towards the base surface in at least one section. The support element also has at least one roof section and at least one base section, whereby the roof section is formed from at least two diagonally upwardly extending roof surfaces and at least one locking tab is arranged at each end of at least one roof surface and / or at least one base surface. The or one base section can be multi-part and comprise one base surface or several base surfaces.

[0009] Here, the "contact edge" of the folded section also refers to one or more sections, so that in an advantageous embodiment, the contact edge at least partially encompasses a shadow area of ​​a triangle, a trapezoid, or a truncated cone. The contact edge also refers to the cut edge in or on the folded section, against which the locking tab can also be brought into contact with its outer cut edge.

[0010] The "carrier element" refers to a tray formed from a blank, hereinafter referred to as the carrier blank, which can be inserted into an outer packaging, the outer box. The carrier element is designed to carry at least one product and, if necessary, can be lifted out of the outer box together with the product, such as one or more toothbrushes.

[0011] Advantageously, the carrier element itself, as well as the blank from which it is formed (shaped), is made of a (fiber) material or a material mixture, such as single- or multi-layer cardboard, corrugated cardboard, carton, composite material, or comparable materials. It is particularly advantageous if the carrier element or the carrier blank is made of a renewable raw material, and furthermore, if the outer box and / or the closure element (lid) are also made of a corresponding material.

[0012] The sub-surfaces and sub-areas of the carrier material, such as the roof surface, floor section, foot surfaces, and locking tab, are separated or connected from adjacent sub-areas or areas by so-called "functional lines." These include embossed lines, scored lines, or perforation lines. Depending on the material and function, a crease line or crease edge can be incorporated into the carrier blank using a tool as one of the aforementioned functional lines, thus predefining and facilitating the shaping of the carrier element into the desired usage or target shape.

[0013] In this case, the flat support cut-out as a support element forms a roof section with at least two roof surfaces that rise from two essentially horizontal floor sections. The major advantage here is that the roof section develops a restoring force via the functional line of the formed gable or ridge and the fold lines at the transition to the floor section. The long edges of the floor sections are thus pressed against the respective side surfaces of the outer box. The roof shape also has the major advantage that it can be grasped and pressed together by a consumer without any additional accessories or handles, so that the support element can be detached from the outer box and removed. The fold line of the roof gable can advantageously also be a functional line that connects the two roof surfaces lengthwise.The term "roof section" refers to the surface portions of the beam section from which the roof-like structure is formed after erection and alignment. The roof section can be formed from two or more sub-sections.

[0014] In one embodiment, an advantage may be that the gable of the roof section has two parallel gable edges, so that a further, possibly strip-like and / or horizontal upper roof surface is formed between the two gable edges in the form of use.

[0015] Surprisingly, a similar effect and advantage was also observed with the locking tabs. These are usually folded upwards from the blank and, when the carrier blank is positioned, slip over at least one folding flap of the outer box because the locking tabs exert a restoring force toward the end faces. After passing over the contact edge, the locking tabs fold out to the lower layer of the end face and thus engage below the contact edge of the folding flap. Since the folding tabs on the end face of the sloping roof surface are arranged along a functional line, they lie diagonally from bottom to top below the respective contact edge of the folding flap.In this way, the support elements and the products arranged there are securely held in the desired position and secured against accidental falling out by the support element pressing and locking itself on the side surfaces and on the end surfaces with a certain spring or restoring force.

[0016] In one embodiment, it may be advantageous if the single- or multi-part contact edge is formed by an opening, a recess, or a cutout in the folding flap. Furthermore, it may be advantageous if the contact edge has contact edge sections that have a course and / or different orientation in at least two spatial directions (yz plane / axes).

[0017] In one embodiment of the packaging unit, an improvement may consist in the folding flap of the outer box being connected to a side surface via a functional line and resting at least partially flat on the front surface with its back. In other words, in this embodiment, the folding flap having the contact edge(s) in the outer box blank is an adjacent surface of at least one side surface, ideally one folding flap on each side surface.

[0018] Here, the term “connected” means that these two partial surfaces are formed from one piece of material or are essentially formed from one (piece) of material.

[0019] In this case, "back" means that it does not face the interior or product space of the outer box, where the carrier blank or the product can be positioned. Similarly, "front" means the side of the outer box material that faces the interior or product space.

[0020] In an improved embodiment, it can be provided that at least one of the cut edges and / or a cut edge section of the locking tab is oriented obliquely to a contact edge in the released position (removal position) such that the cut edge and / or the cut edge section can slide off the contact edge. In this case, the "released position" of the cut edge means that the roof surfaces of the support element have been pressed together a defined distance and / or moved toward each other, so that the locking tabs are no longer in force-fit and / or form-fit connection with the contact edges (end position).

[0021] In a further embodiment of the packaging unit, an improvement can be achieved by connecting the folding flap of the outer box to a front face via a functional line, and resting at least partially flat on the side face with its back. In other words, in this embodiment, the folding flap having the contact edge(s) in the outer box blank is an adjacent surface of at least one front face, ideally one folding flap on each front face.

[0022] In one embodiment, it can be provided that the aforementioned variants are combined in that a folding flap of the outer box is connected to a side surface via a functional line and a folding flap of the outer shafts is connected to a front side via a functional line.

[0023] In a further embodiment of the packaging unit, an improvement may consist in at least one locking tab being arranged at each end face of each roof panel and / or each base panel. In other words, a locking tab protrudes (obliquely) upwards at each end face of the roof panels when inserted.

[0024] In a further embodiment of the packaging unit, an improvement can be achieved by forming at least one clamping and positioning section from at least one base section, which extends transversely beyond the longitudinal edge. This clamping and positioning section can essentially have two functions. Firstly, it forms a second clamping line on the side surface of the outer box, and secondly, it centers a product that is inserted between the inward-facing surface of the clamping and positioning section and the respective roof surface.

[0025] Based on an elongated extension of the outer box and thus also of the support element with a longitudinal axis, “longitudinal direction” means the x-axis of a Cartesian system, “transverse direction” the y-axis and “up or down” the z-axis.

[0026] In a further improved embodiment of this variant, at least one side surface of the outer box has at least one contact element, beneath which at least one clamping and positioning section can engage in the use position. This represents a further advantage of the compressible roof surfaces of the support element. These additional locking sections on the contact element are also unlocked or released with the same user action, allowing easy removal of the support element at any time.

[0027] The clamping and positioning section is advantageously formed at least partially from the base section or the foot surface and, in the unfolded position, extends transversely beyond the longitudinal edge of the base section by a defined distance. Thus, a crease line is arranged longitudinally at the transition from the base section to the clamping and positioning section, and cutting lines are arranged transversely on both sides of the clamping and positioning section at the transition to the base section. In the following, no distinction is made between cutting line and cutting edge; the terms are used synonymously, because a cutting line in the blank represents one or two cutting edges after unfolding.

[0028] For this embodiment of the packaging unit, in which at least one base section is formed into at least one clamping and positioning section which projects transversely beyond the long edge, an improvement could be that at least one clamping and positioning section is folded upwards when the support elements are inserted in the outer shaft. This means that the clamping and positioning section projects diagonally upwards in the direction of the z-axis. The angle of inclination of the clamping and positioning section depends on the length in the transverse direction (y-axis) by which the long side of the base section is projected over and the distance in the transverse direction of the fold line parallel to the long axis in the transition from the base section to the clamping and positioning section.

[0029] Advantageously, at least one clamping and positioning section and / or one roof surface has at least one (product) recess for receiving or inserting at least parts of the product. This can be, for example, a toothbrush head that rests on the support element facing the center and is accommodated in a (product) recess of the roof section. Preferably, two toothbrushes are positioned opposite each other in this manner, and a recess is provided in each roof surface, either at the same or at the opposite end faces.

[0030] A further improvement of this embodiment of the packaging unit can be achieved by having at least one roof surface, formed by at least one cutting line, particularly two-sided cutting lines, form the base section, which has inner base sections projecting inward in the transverse direction, particularly for placing and inserting a product end (toothbrush head) and / or as an access area for removing a product. In other words, these inner base sections are arranged in the shadow area of ​​the roof section projecting in the z-axis direction.

[0031] In a further embodiment of the packaging unit, an improvement can be that the packaging unit has at least two carrier elements stacked one above the other for receiving at least one product each, wherein - a folding flap of an end face has at least four contact edges arranged opposite one another in pairs and one above the other in pairs, or - two opposing folding tabs of one end face each have at least two superimposed (jointly opposing) contact edges, and wherein each pair of (horizontally) opposing contact edges has in at least one section a (horizontally) distance increasing towards the base surface, in which the at least one locking tab of one of the support elements can be brought into contact.

[0032] This doubling of the support elements in the direction of the z-axis as well as further levels of support elements follow in an analogous manner the above-mentioned embodiment and its concept.

[0033] The complementary attachment edges of the folding tabs to the respective locking tabs are provided on the folding tabs at the desired frequency n, one above the other (z-direction). During assembly, the lowest support element 1 is inserted first and the uppermost support element n last. During removal, as described above, the uppermost support element n is first at least partially released from the locking position by grasping and pressing the roof surfaces together, and can then be removed.

[0034] With this stacking of n support elements, the underside of the base section can rest on the products below. Advantageously, inner base sections are provided that extend transversely toward the center (longitudinal axis) and rest on or against an underlying roof surface with a partial surface and / or their respective inner edge.

[0035] In a further embodiment of the packaging unit, an improvement may consist in the locking tabs being folded upwards in the inserted position of the carrier element in the outer box.

[0036] The invention is explained in more detail below with reference to exemplary embodiments and the figures. They show: Fig. 1 a perspective top view of the packaging unit, Fig. 2 a top view of the carrier blank, Fig. 3 a perspective view of the released support element, Fig. 4 a further plan view of an alternative design of the carrier cut, Fig. 5 a perspective top view of part of the front side, Fig. 6 a vertical sectional view looking towards the inner end face of the outer box and Fig. 7 one to Fig. 3 alternative embodiment.

[0037] Identical reference numerals are used in the figures for identical or equivalently functioning elements of the invention. Furthermore, for the sake of clarity, only those reference numerals are shown in the individual figures that are necessary for the description of the respective figure. Furthermore, the invention is shown in the figures only as a schematic view to explain its operation. In particular, the representations in the figures serve only to explain the basic principle of the invention. For reasons of clarity, all components of the device have been omitted.

[0038] The Fig. Figure 1 shows a top view of the packaging unit 300 with a slightly unfolded outer box 101, on whose bottom surface 102 the carrier element 201 is placed in an upright position. The packaging unit 400 shown comprises an outer box 101 and a carrier element 201 for accommodating two toothbrushes 130, each with a brush head (product end 132, front) and a toothbrush handle (product end 134, rear).

[0039] The outer box 101 comprises a base surface 102, at least two side surfaces 104, and at least two end surfaces 106. Folding flaps 110 are arranged on the end surfaces 106 for at least partial contact with the respective end surface 106 in the closed, finalized state. The folding flaps 110 have recesses 150 as openings or cutout areas, at which contact edges 112 are arranged. Furthermore, a closure flap 120 is arranged on each of the side parts 104 and an end surface 106, which serves to support and connect to a closure element (not shown). The closure flap 120 protrudes outwards along the functional line F and can, for example, be glued, welded, or otherwise connected to a closure element. In this case, the functional lines F are punched lines that specify a defined bend in the material of the outer box.

[0040] The support element 201 has two end faces 206, two longitudinal edges 208, a roof section 210, and base sections 220. Two locking tabs 250 are arranged at each end face 206, with one locking tab being arranged on each roof surface 211 at each end face 206. When the outer box 101 is closed, the locking tabs 250 of the support element 201 engage the contact edges 112 of the folding flap 110 arranged in the recesses 150 and can be locked there. The folding flaps 110 and the recesses 150 therein each have two contact edges 112, an outer and an upper one.

[0041] A toothbrush, as product 130, is inserted onto the carrier element 201, by way of example. The toothbrush has a front product end 132, a toothbrush head, and a rear product end, a toothbrush handle. A second toothbrush can be inserted analogously below in the image plane, with the toothbrush head, the front product end 132, also oriented toward the center (upward).

[0042] As in connection with the Fig. 5 and Fig. 6, the opposing folding tabs 110 of an end face 106 each have at least one (jointly opposing) contact edge 112. The opposing contact edges 112 are spaced apart from one another at a distance increasing toward the base surface 102. The support element 201 has a roof section 210 and a base section 220. The roof section 210 is formed in a gable-like manner from two obliquely upwardly projecting roof surfaces 211 and has locking tabs 250 at each end face 206.

[0043] The representation of the Fig. 1 is for illustrative purposes only. The carrier element 201 is intended to be inserted into the finished outer shaft 201, not into an open, unfinished outer box 201.

[0044] In the Fig. 2, the support blank 200 is shown as a flat, unerected element from which the support element 201 is formed. The support blank 200 consists of a one-piece cardboard material or paperboard. In the embodiment shown, the support blank 200 has a roof section 210, a base section 220, clamping and positioning sections 230, a central folding axis 202, two outer folding axes 204, two end faces 206, and outer longitudinal edges 208. The roof section 210 comprises two roof surfaces 211, on which locking tabs 250 are formed at the end faces 206. However, the two outer folding axes 204 do not later form a continuous folding line in the erected support element 201, but are interrupted, for example, by the inner base surfaces 224. The central folding axis 202 is one of the functional lines F, which is formed as a folding and perforation line 252. The longitudinal axis L runs in the same position.In the embodiments of the figures, it is largely left open how the functional lines F are mechanically formed, ie whether they are perforated, cut or punched, for example.

[0045] The locking tabs 250 are trapezoidal in shape. The floor section 220 is divided into two sections, an upper and a lower section in the image plane, on both sides of the roof section 210. A bending axis 204 is provided at the transition between a roof surface 211 and the adjacent outer base surface 222. Cutting areas and corresponding cutting lines 232 extend from the bending axis 204, forming the inner floor sections 224. Fig. In Figure 2 and the other illustrations, only individual cutting lines 232 are shown. Functional lines F, cutting and / or folding lines are self-explanatory from the illustrated erected support elements 201.

[0046] This inner base surface 224, together with the resulting cutout area in the compartment surface, forms a receiving space / area for, for example, a transversely projecting section of a product 130, such as a toothbrush head (not shown). Furthermore, the longitudinal axis L (x-axis) and the transverse axis 205 (y-axis) are shown.

[0047] In the Fig. 3, the released support element 201 is according to Fig. 1, where the Fig. 4 shows the corresponding carrier cut 200. Fig. Figure 3 shows an upright or unfolded position of the support element 201. The two roof surfaces 211 are oriented upwards in a gable-like manner in the direction of the vertical axis 207 (z-axis). Locking tabs 250 are arranged at each end face 206 of each roof surface 211 of the roof section 210, so that the support element 201 has a total of four locking tabs 250.

[0048] In an embodiment not shown, only two locking tabs 250 are provided, for example, offset at the two end faces 206. The support element 201 is shown in a position in which the roof surfaces are brought closer together such that the inner edges of the (inner) foot surfaces 224 touch. This can be the released position, whereby the inner foot surfaces 224 can also be deformed and / or slid over one another by further force applied by a user.

[0049] The partial section acc. Fig. Figure 5 shows the open outer box 102 with an end piece 114 arranged there, which has an eyelet 116, which serves for attachment to a support element (not shown). The inserted and erected support element 201 has a certain distance from the end face 206, wherein the locking tabs 250 create a locking and, to a certain extent, a resilient mounting due to the restoring forces. The embodiment of the partially illustrated support element 201 in the Fig. 5, which is in the Fig. 3, Fig. 4 and Fig. 6. It can be seen that when the two roof surfaces 211 are manually pressed or folded together, with the ridge constituting a type of leaf or foil hinge, the locking tab 250 is at least partially pulled over a contact edge 112 and thus released to such an extent that the support element 201 can be removed without significant resistance when the roof surfaces 211 are thus grasped and brought closer together. In particular, the upper locking edge 256 is guided transversely inward toward the center to such an extent that the lateral locking edge 254 rests in the area of ​​the upper contact edge 112 or the upper contact edge section and can slide off.

[0050] Fig. Figure 6 shows the entire packaging unit 400 of an exemplary embodiment in a vertical section in the closed form. This comprises an outer box 101, a closure element 300, and the carrier element 201. In particular, the opposing folding flaps 110 of an end face 106 and the recess 150 therein with the associated contact edges 112, which are formed as two contact sections with different spatial orientations, are visible in detail.

[0051] The folding tabs 110 are snapped, glued or otherwise attached in an inconspicuous manner to the respective rear side on the front side 106.

[0052] The contact edges 112 of the left and right recesses 150 are opposite each other and form a (transverse) gap in the transverse direction (y-axis) that opens or widens toward the base surface 102. The two contact edges 112 of the left and right folding flaps form an angle, which in an alternative embodiment can also be an arc or other curved line. The locking flaps 250 have two complementary locking edges 254, 256. The lateral locking edge 150, in the position shown, is opposite the lateral contact edge 112 (contact edge section) of the folding flap 110, and the upper locking edge 256 is opposite the upper contact edge 112 (contact edge section). Fig. 6 shows a situation in which the support element 201 is not fully erected, so that the longitudinal edge 208 of the outer foot surface 222 does not abut the side surface 104. Thus, the locking edges 254, 256 of the locking tabs 250 are not at least partially in contact with the contact edges 112 of the folding tabs 110.

[0053] Clearly visible is the advantageous locking mechanism, which is easy for a user to manipulate, in two directions: diagonally upwards and (crosswise) to the side.

[0054] Furthermore, in the Fig. 6 an alternative embodiment for the folding flap 110 is indicated by the dashed line, which is open to the base surface 102, whereby the base surface has a more web-like or hook-like shape.

[0055] Finally, in the Fig. 7 shows an embodiment of the carrier element 201 which, except for the arrangement of the locking tabs 250, corresponds to the embodiment of the Fig. 3 is identical, so reference is made to the explanations therein. The contact edge, which is designed to complement the locking tab arranged on the (outer) base surface, is preferably not part of a recess of a folding tab. This folding tab for a locking tab arranged on the edge of the base surface preferably has an open shape directed towards the bottom surface of the outer box. In other words, this is a base surface, which is designed, for example, like a web-like or hook-like structure. In other words, which is designed like a type of overhang.

[0056] In the present case, the packaging unit and the associated elements, such as the carrier blank, the carrier element and / or the products, are shown essentially in one position and orientation, namely resting on a horizontal surface (not shown). It will be understood by those skilled in the art that the packaging unit and the associated elements, individually or jointly, can assume any position and orientation. Thus, all terms and references to spatial position, such as top, bottom, vertical, diagonal, etc., as well as terms that indicate a spatial position, such as "floor," "ceiling," "side," etc., serve only to simplify the language. They are not to be understood as limiting, and are to be understood and interpreted analogously if the basic orientation of the packaging unit or the associated elements changes.
