BACKGROUND OF THE INVENTION

The invention relates to a packaging system with tablet-type objects, particularly friable tablets, with a polygonal exterior packaging formed from a folding blank of cardboard or the like and with film pouches which are individually arranged in the exterior packaging and in each of which at least one tablet-type object is received.

Washing and/or cleaning agent in tablet form, which, for example, due to their hygroscopic properties require additional protection against mixture, are generally packaged in film pouches. So-termed ‘flow packs’, which consist of a film tube pouch having a longitudinal seam and two transverse seams, so-called ‘fins’, have, by way of example, proved themselves in practice for that purpose. The production of such ‘flow packs’ is known and usually takes place on high-performance production plants directly after tablet manufacture. Such a film pouch is known from, for example, DE 295 09 593 U1.

Tablets wrapped in film pouches of that kind (individual or multiple wrapping) are loosely packed in a packaging container, such as a packet, carrier pack, drum or the like, which basically represents a sufficiently stable outer packaging or exterior packaging for storage and transport. In that case stability refers to the requisite compression resistance of the package in the event of pressure loading and weight loading within a pallet unit.

Washing agent tablets of that kind are, however, friable products which in general are loaded during the filling process and during transport in such a manner that edge breakage, fracture and abrasion cannot be avoided even with the usual rigid outer packaging. The tablet is also not protected with respect thereto by the film pouches, which offers only a slight additional protective effect relative to shock loading and in transport.

Packaging of the kind in question has become known from DE 198 52 936 A1 of the applicant, in which the film pouches are individually arranged in the exterior packaging with longitudinal seams aligned parallel to one another, wherein the length of the film pouches is greater than the spacing of the lateral walls—which are parallel to the transverse seams of the film pouches—of the exterior packaging in such a manner that at least one end region of the film pouches lies resiliently bent over in the exterior packaging and that at least the lateral walls, which are parallel to the longitudinal seams of the film pouches, of the exterior packaging are furnished with wall reinforcements. In the case of such a form of packaging, shock loads parallel to the longitudinal seam in the foil pouches are absorbed relatively satisfactorily at the outset by the segregated arrangement of the film pouches in the packaging, these shock loads being partly absorbed by the bent-over fins (transverse seams) of the film pouch. Since the film pouches are in additional designed to be longer than the respective package length (spacing of the lateral walls, which are parallel to the transverse seams of the film pouches, of the exterior packaging), at least one of the two fins of each film pouch is bent over when inserted into the exterior packaging, so that the fin lies resiliently in the exterior packaging, whereby shocks can be damped without giving rise to damage of the tablet-shaped products. Shock loads parallel in longitudinal direction of the film pouch thus cannot lead to damage of the tablets. Shock loads in transverse direction, i.e. parallel to the transverse seams, are absorbed by the special design of the exterior packaging with wall reinforcements in the corresponding lateral walls of the same.

This known packaging with a rectangular base cross-section thus offers significant advantages, but it is still worthy of improvement since due to the round, tablet-shaped objects there are cavities within the packaging, particularly in the corner regions, which impair the strength thereof.

A tablet, preferably a water-soluble cleaning agent tablet, is known from WO 99/50381, which is to have special strength characteristics primarily due to a special geometric shape.

Box-shaped packaging for reception of bottles or the like is known from DE 93 20 302 U1, which has an octagonal base surface. In that case the bottle-shaped objects are arranged on the base surface and subsequently the packaging lateral walls are folded in around the bottle-shaped objects. Completely different objects having nothing in common with washing or cleaning agent tablets packed in film pouches are obviously involved. A packaging blank with an octagonal base surface is also known from FR 2 780 703 A1.

DESCRIPTION OF THE INVENTION

It is the object of the invention to so further develop a packaging system of the kind in question that the strength thereof, particularly the stacking compressive pressure thereof, is increased and the mechanical loads on the tablet-shaped objects are further reduced.

According to the invention this object is fulfilled with a packaging system of the kind denoted in the introduction in that the folding blank has an at least octagonal base surface, which is formed symmetrically with respect to the centre, with two longitudinal edges and two narrow edges as well as with four short edges—which are adapted to the contour of the tablet-shaped objects—in the corner regions, wherein lateral walls able to be connected together are pivotably connected with the longitudinal edges and the narrow edges.

It has proved that through segregated arrangement of the tablet-like objects in the exterior packaging and matching of the corner regions of the exterior packaging to the contour of the tablet-like objects disposed in the corners the corner regions of the exterior packaging are substantially more stable, so that kinking in of the exterior packaging in the corner region is largely avoided and no transverse loading is exerted on the tablet-like objects in these regions. Moreover, the stacking compressive pressure of the packaging is significantly increased by these measures, so that several such packages can be stacked on, for example, a pallet without thereby prejudicing the tablet-shaped objects. Moreover, damage of packages, which are stacked on pallets, in the corner region by packing material such as stretch film is avoided, since the corners are not pressed in by the transverse loads. The packaging system according to the invention is protected from external influences along the entire circumferential surface.

Moreover, the packaging can be more easily handled, since it is readily possible to grip it, depending on the respective size of the packaging, by, for example, one hand. Cutting of the corner edge of the exterior packaging into the region between index finger and thumb is precluded by the flattened corner region and the risk of injury thus diminished.

In addition, a significantly reduced blank and cardboard consumption and thus reduced packing material costs can be achieved. Moreover, the exterior packaging can, by virtue of the corner design, also be used free of problems in a reusable container already in the hands of a user.

With particular preference narrow lateral wall parts respectively corresponding with the length of the corner edges are pivotably connected with two opposite lateral walls at the edges. In this design the blank can be produced in particularly simple and material-saving manner, since the narrow lateral wall parts forming the corner regions are pivotably connected with only two of the four lateral walls.

If the packaging has more than eight corners, it is proposed in a another embodiment that further narrow lateral wall parts are pivotably connected with the narrow lateral wall parts, wherein the overall length of all narrow lateral wall parts corresponds with at least the length of the corner edges. The narrow lateral wall parts are then appropriately adapted to the corner construction. For example, a sixteen-sided base surface can be provided.

In order to achieve a particularly good adaptation to the contour of the tablet-shaped objects in the corner regions, the corner edges are, with particular preference, formed to be radiused towards the outside, wherein the radius amounts to between 10 to 50 millimetres, preferably 20 to 40 millimetres and particularly preferably between 25 to 35 millimetres. Beyond that, this form of embodiment leads to even better sealing of the closed packaging and, in addition, the overall compressive pressure of the packaging can thereby be even further increased.

In order to further enhance the strength of the packaging, it is provided with particular preference to pivotably connect respective adhesive flaps, the width of which corresponds with at most the width of the associated lateral wall, by way of fold lines to each of the opposite narrow lateral wall parts at the edges. The relevant lateral wall in the case of this embodiment is then formed to be triple-layered, wherein this can also be provided only in sections in a lower region of the lateral wall.

In addition, preferably the lateral walls pivotably connected with the longitudinal edges have a length corresponding with the height of the packaging and the lateral walls pivotably connected with the narrow edges are preferably formed to be shorter. The narrow sides are then formed partly by the short lateral walls and over the entire height by the corresponding adhesive flaps.

In that case, the lateral walls pivotably connected with the narrow edges preferably have approximately half the length of the lateral walls, together with narrow lateral wall parts and adhesive flaps, pivotably connected with the longitudinal edges and the width of the adhesive flaps approximately corresponds with the width of the associated narrow lateral walls.

In addition, adhesive flaps, the width of which is preferably smaller than the corner edge, are preferably arranged at the narrow lateral walls by way of fold lines.

In order to further simplify production of the packaging it is further provided that a cover part is pivotably connected by way of a fold line with at least one wide lateral wall at the top as seen in position of use. The pivotable connection can be effected by way of either a fold line or a perforation line, if the cover is to be capable of being easily torn off.

The cover part is preferably constructed to be removable so that the packaging can be inserted into a reusable container. For that purpose the cover part is pivotably connected by means of, for example, a perforation line.

The folding blank of the packaging system can preferably consist of cardboard or corrugated cardboard, wherein the material of the folding blank preferably has a flat crush resistance of 100 to 4,000 N, preferably from 1,000 to 3,000 N, particularly preferably from 1,500 to 2,800 N.

If the folding blank consists of corrugated cardboard, the corrugated cardboard preferably has an F or E wave profile, wherein in the case of an E wave profile (DIN 55486 Part 1) a wave pitch of 3 to 3.5 mm and a wave height of 1.0 to 1.8, preferably 1.4, mm is provided and in the case of an F wave profile a wave pitch of 2 to 3 mm, preferably 2.38 mm, and a wave height of 0.6 to 1.0 mm, preferably 0.78 mm, is provided.

If the folding blank consists of solid cardboard, a solid cardboard with 350 to 600 g/qm, preferably 450 to 500 g/qm, is preferably used.

The tablets preferably have a diametral fracture hardness of 10 to 200 N, preferably 30 to 70 N, particularly preferably 35 to 55 N, wherein each tablet is protected by the film pouches and/or the exterior packaging against transverse loads.

Preferably several, especially two, tablets are arranged adjacent to one another in longitudinal direction of a film pouch, wherein their centre axes are aligned to be parallel. In that case preferably several film pouches are arranged separately in the exterior packaging to be parallel to one another in longitudinal direction, wherein several film pouches form a layer parallel to the base surface.

The length of the film pouches between transverse seams closing them at the ends preferably corresponds approximately with the width between two opposite lateral walls of the exterior packaging. In that case the length of the film pouches between transverse seams closing them at the ends is preferably greater than the width between two opposite lateral walls of the exterior packaging, so that at least one end region of the film pouches is bent over to bear against the lateral wall, whereby shocks can be resiliently damped.

With particular preference in that case two end regions of the film pouches are bent over to bear against the corresponding lateral walls.

The film pouches of the packaging system preferably consist of a film with the following parameters: water vapour permeability (23° C., 85% r.h.) (according to DIN 53122) between 0.7 to 1.5 g/qm/24 h, preferably 0.9 to 1.3 g/qm/24 h, particularly preferably 1.0 g/qm/24 h, modulus of elasticity (according to DIN 53455) 1,200 to 2,500 N/qmm, preferably 1,800 N/qmm, tensile strength (according to DIN 53455) 150 to 500 N/qmm, preferably 250 N/qmm, thickness 20 to 40 μm, preferably 25 to 35 μm, particularly preferably 30 μm.

Moreover, the film pouches preferably consist of a sealable film, particularly a cold-sealable film or a film sealable at low temperature, such as co-extruded OPP film.

DETAILED DESCRIPTION OF THE DRAWINGS

A packaging system according to the invention with tablet-type objects, particularly friable washing and/or cleaning agent tablets, is denoted in FIG. 1 generally by 20. The packaging system 20 comprises a closed exterior packaging 21 and a plurality of film pouches 22, in each of which, in the case of the embodiment, two tablet-shaped objects 23 with a diameter of approximately 44 millimetres and a height of 19 millimetres are received adjacent to one another, wherein the diametral fracture hardness amounts to between 20 to 100 N. These film pouches 22 are closed in usual manner by a longitudinal seam and at both ends, with formation of so-called fins, by transverse seams as is known from, for example, DE 198 52 136 A1. However, the film pouches in the form of a tube can also be closed only by transverse seams. The film pouches 22 together with the tablet-shaped objects 23 disposed therein are arranged within the exterior packaging 21 to be stacked one above the other segregated in parallel rows, as evident from FIG. 1. In an exterior packaging (size for thirty) the thirty tablets are arranged in five layers each with three parallel film pouches.

As further evident from FIG. 1, the exterior packaging 21 has a cover 24 which can be pivoted up and which in closed position is lockable by means of flaps 24a provided at the opposite upper edge of the cover fold line.

Of significance for the form of the packaging system 20 is the corner construction of the exterior packaging 21, these corner regions being denoted in FIG. 1 by E.

As best evident from FIG. 2, according to a first embodiment the base surface 1 is formed to be octagonal with two longitudinal edges 25, two narrow edges 26 and four short edges in the corner regions, which are adapted to the contour of the tablet-shaped objects 23. Suitable dimensions (width of the longitudinal edge×width of the narrow edge) for the base surface 1 are 142 millimetres×95 millimetres, wherein the corner edges form relative to the other edges an angle of approximately 45°, but other angle combinations are also possible. The height of the exterior packaging amounts to approximately 125 millimetres in the case of a thirty-size.

The form of embodiment according to FIG. 3 shows an even better adaptation to the contour of the tablet-shaped objects 23, in which each corner region E has, due to a twelve-sided shape of the base surface 1, two short corner edges 27.

Through this embodiment of the corner regions E a cavity between the tablet-shaped objects 23, which are received in the film pouches 22, and the exterior packaging 21 can be almost completely avoided, so that kinking in of the corner regions by transverse loads is securely avoided. The stacking compressive pressure of the exterior packaging can thereby be substantially increased and in addition grasping or gripping of a package 20 even by one hand is possible substantially more simply.

Different forms of embodiment for the design of the exterior packaging 21 are illustrated in FIGS. 4 to 9 on the basis of differently shaped folding blanks.

In the form of embodiment according to FIG. 4 the folding blank has at the outset an octagonal base surface 1 having a length a and a width b. In that case the length a and the width b are so selected that they correspond approximately with a whole-number multiple of the diameter of the tablet-shaped objects 23. If a is larger than b, as illustrated in FIG. 4, wide lateral walls 2, 3 are pivotably connected with the longitudinal edges 25 by way of fold lines and form the front and rear wall, respectively, and narrow lateral walls 4, 5 are similarly pivotably connected with the narrow edges 26 by way of fold lines and form the left and right lateral wall, respectively.

The ends of the longitudinal edges 25 go over into the narrow edges 26 by way of the short corner edges 27. In that case the corner edges 27 in the octagonal base surface 1 are so aligned that they form a tangent to the tablet-shaped objects 23 (not illustrated in FIG. 4) arranged in the corners of the packaging, the associated radius, which is arranged at right angles thereto, of the tablet-shaped object 23 (indicated only schematically) being denoted in each instance by s.

Narrow lateral wall parts 7 and 8 or 6 and 9 are pivotably connected by way of fold lines with the front or rear wall 2 or 3. The width of these narrow lateral wall parts 6, 7, 8, 9 in that case corresponds with the length of the corner edges 27. Respective adhesive flaps 4a, 4b, 5a, 5b, the width of which corresponds with the width of the lateral walls 4 and 5, are pivotably connected by way of fold lines with these narrow lateral wall parts 6, 7, 8, 9 at the outer side. On folding of the folding blank for formation of the exterior packaging 21 from the flatly disposed blank there is effected, by way of the mutual adhesion of the adhesive flaps and lateral walls 5, 5a and 5b or 4, 4a and 4b, formation of a stable righthand or lefthand lateral wall; it is then recognisable, at least in the lower region thereof which is then of triple-layered construction, that in the folding blank according to FIG. 4 the height L of the adhesive flaps 4a, 4b, 5a, 5b is greater than the height of the lateral wall 4, 5.

The film pouches 22 with the tablet-shaped objects 23 disposed therein are then inserted, segregated, in the thus-erected exterior packaging 21, so that the tablet-shaped objects 23 disposed in the corner regions bear tangentially against the corner edges 27 whereby cavities in the corners are avoided. Due to the stable, multi-layer lateral walls 4, 5 with multiple adhesion the tablet-shaped objects 23 are protected against impacts or other external loads.

A modified form of embodiment of a folding blank is illustrated in FIG. 5, wherein the same reference numerals as in FIG. 4 are used insofar as the same parts are concerned.

By contrast to the form of embodiment according to FIG. 4 additional adhesive flaps 6a, 7a or 8a, 9a are pivotably connected by way of fold lines with the side walls 4 and 5 at both edges, so that adhesion of the adhesive flaps 6a, 7a, 8a, 9a with the narrow lateral wall parts 6, 7, 8 or 9 takes place when the folding blank is folded. The narrow lateral walls are thus also appropriately reinforced and stabilised in the corner regions, whereby an additional protection for the tablet-shaped objects 23 disposed in the exterior packaging is effected. In order to achieve a particularly stable package, particularly a package with very high stacking compressive pressure, a continuous gluing by several glue seams arranged in parallel and extending over the entire lateral wall length L is recommended. In the finished package the lateral wall length L corresponds with the package height.

A further form of embodiment of a folding blank for packaging is illustrated in FIG. 6. This form of embodiment differs from that according to FIG. 4 by an additional cover part. This cover part has at the outset a cover wall 10 which is pivotably connected with the upper edge of the side wall 2 by way of a fold line. This cover wall 10 has a length c and a width d, which are respectively slightly larger than the length a and the width b of the base surface 1. Side walls 11, 12, 13, 14 and 15 are pivotably connected with this cover wall 10. Flaps 11a and 11b are again pivotably connected by way of fold lines with the lateral walls 14 and 15 and are glued with the lateral wall 11 in the erected state of the folding blank, so that a packaging lid which is simple to open and close is thereby created.

The form of embodiment according to FIG. 7 differs from that according to FIG. 4 in that the folding blank has, in the region of the corners, narrow lateral wall parts 6, 7, 8 and 9 each divided by two additional fold lines into three adjacent sections. Two corners thereby additionally arise in each of the corners in the folded-up state, so that the cross-section of the erected lateral walls is thus sixteen-sided in this example of embodiment. The base surface 1 is also correspondingly constructed in the corner regions, i.e. the corner edges 27 consist of three different sections.

FIG. 8 shows a further form of embodiment. This corresponds with that according to FIG. 6, with the difference that the cover wall 10 of the cover part is pivotably connected with the lateral wall 2 not by way of a fold line, but by way of a perforation line P. This makes it possible to tear off the cover entirely after opening of the packaging, if this is desired.

FIG. 9 shows yet another further form of embodiment of a folding blank. This form of embodiment differs from that according to FIG. 4 in that the corner edges are radiused outwardly, which is indicated by the radii R. The base surface 1 is thereby polygonal if the radiused corners are regarded approximately as a plurality of corners. During the processing process in the filling line the obliquely disposed narrow lateral wall parts 6, 7, 8, 9 thereby position themselves substantially automatically between the base surface 1 and the cover wall 10. This leads to a higher degree of sealing of the closed packaging and to an additional increase in the overall compressive pressure of the packaging. Moreover, the closed exterior packaging offers a cleaner appearance. The radius R of the rounded corner regions lies between 10 and 50 millimetres, preferably between 20 and 40 millimetres and particularly preferably between 25 and 35 millimetres.

FIG. 10 shows the possibility of using an opened packaging system 20 in a reusable container 28. If the exterior packaging has a lid, there is preferably used such a folding blank as is illustrated in FIG. 8, i.e. with a cover wall which is articulated by way of a perforation line P and which enables simple tearing off of the lid.

It is also recognisable from FIG. 10 that the packaging system according to the invention enables, relative to conventional packaging with a rectangular cross-section, insertion into a reusable container 28, because as was apparent a package with a rectangular cross-section and an approximately equal base surface does not fit into the reusable container 28.

Finally, there is shown in FIG. 11 a folding blank which largely corresponds with that according to FIG. 4. In addition, however, glue seams are illustrated. In that case, glue seams LN1 extend over the entire height (length L) of the adhesive flaps 4a and 4b, whilst glue seams LN2 at the adhesive flaps 5a and 4b are shorter. These are initially glued to the lateral walls 4 and 5 and subsequently gluing to the adhesive flaps 5b and 4a is carried out by way of the long glue seams LN1.

Apart from the afore-described advantages a package made from a folding blank according to FIG. 4 also has a significant material saving. Thus, by comparison with a conventional package with a rectangular cross-section there can be achieved, depending on the packaging size or the number of received tablets, the following savings of area:

Blank area (m2): Number of rectangular packaging received tablets packaging according to FIG. 4 Area reduction 30 0.146069 0.117489 19.50% 36 0.163340 0.136559 16.40% 48 0.193369 0.1658120 14.25% 56 0.208718 0.180368 13.50% 64 0.228423 0.198161 13.25% 72 0.246021 0.211660 14.00%

A comparison of the specific strength (crush pressure) of the standard box, which is currently used by the applicant, with a rectangular base surface for thirty tablets with the packaging system according to the invention for thirty tablets (according to FIG. 6) shows that the specific strength (overall strength referred to the area of the lateral walls positioned at the narrow edges) in the packaging system according to the invention is substantially higher. Moreover, the influence of the form of gluing was investigated and it was established that in the case of the packaging system according to the invention continuous gluing over the height of the lateral wall is advantageous relative to gluing interrupted over the height. In the case of the known standard box, no influence by the kind of gluing was established.

The following results were ascertained by laboratory tests:

Packaging System Standard Box* according to FIG. 6** total specific value total specific value Hot Melt Coating Value N N/mm value N N/mm closed 1785 18.5 1680 27.3 tracks points, 1824 18.9 1520 24.7 beads/1 cm long
*flat width: 96.5 mm

**flat width: 61.5 mm

The specific strength for the different designs of the packaging system according to the invention is between 30 to 70 higher than in the case of the known standard box with rectangular cross-section.

Obviously the invention is not restricted to the illustrated examples of embodiment, for example exterior packaging with lateral walls of the same width can be equally developed in accordance with the invention. Further embodiments are possible without departing from the basic concept.
