Description

The present invention relates to a banderolenarti cut packaging material for packaging a Majority of containers, for example cans, fla or the like, with an upper part, with the upper part in Connected side walls as well as on the sides walls adjacent floor parts, which in the folded or pre-folded state can be connected, with upper part, side walls and / or bottom parts one or more parts lig are formed, and an additional bracket Containers on the respective side area of the blank is provided.

With such band-like blanks, a Most containers, for example six limona de-cans on the four main side surfaces of the cans order involved, with the cans on the two sides ten areas of the can assembly, d. H. on the side area the cut be secured against falling out have to. This backup has been used in the past for example by using additional tapes performed which folded the side areas of the At least partially close the blank and here prevent it from falling out of the cans. Furthermore one has already gone over with side stripes fold in, which also causes the cans to fall out should prevent. The previous measures designed itself - especially for containers with a round exterior contour - complex, provided a certain stability or Packaging quality should be achieved. In spite of of the measures of the prior art described above Technology was a compact packaging and a center  container inside the packaging always guaranteed.

The object of the invention is the genus further training in such a way that this is possible is as easy to manufacture and fold as possible increased security against tearing open a very compact packaging enables.

This object is achieved in that as a holder, foldable and / or swiveling upper, lateral and lower side flaps are provided, which after folding at least partially with each other or are connected to each other, to each other Adjacent side flaps over a folding area in connection which neighboring side flaps fall connected state and folded is, whereby all side flaps or at least at least part of it in the folded state of the blank adapts / adapt the outer contour of the containers. The Packaging material blank according to the invention is suitable net, a plurality of especially round containers full, d. H. also around safely on the side areas close, with the side flaps of the Outer contour of the containers in the corner areas of the ge pleated cut hugs, which on the one hand quite attractive design can be achieved, a ver Larger advertising space available for advertising prints stands and finally due to the full range Wrapping the containers even a weaker mate rial, for example a weaker cardboard used can be without taking the risk that the Tear open packaging during transport or the like. Through the compact integration of the containers through which he measures according to the invention can be achieved, he will  increased transport safety on pallets (i.e. with pallet packaging) and increased carrying safety guaranteed when carrying the individual packaging. In addition, the complete completion of the Side areas ensure effective light protection. The packaging according to the invention or the fiction moderate packaging material cutting is therefore particularly important also suitable for glass containers which are light sensitive Include liquids. The pre-invented see folding surfaces due to the connection the individual side flaps one below the other special stability of the overall packaging. The folding surface Chen also ensure the advantage that after the folding of the blank over the folding surface of the outer side tabs a force on the inside lying, d. H. on the sides of the container Side tabs is transmitted, creating an additional Increasing the stability of the containers within the packaging is guaranteed. This through the folding surface Chen transmitted force causes during the folding of the Cut that the cut is tight around the whole Arrange the containers around and the containers nisse be additionally centered. The cut literally extends around the corner areas of the arrangement of the Containers around. In addition, the cutting is very easy to manufacture, d. H. there are only a few areas to punch out, the blank has i. w. Rectangular shape, it is easy to store or stack and can close and finally, in a simple way, mechanically are folded and causes far less cardboard packaging cut, d. H. Committee.

The folding surface is expediently designed in this way and / or arranged that folded over the folding surface state of the blank a supporting effect between  the adjacent side surfaces can be achieved. The Be ten flaps are folded at the end of the folding process, with two opposite flaps folded inwards and then the two adjacent tabs folded over it. This will support the effect of the folding surface in connection with the curved External contour of the containers reached that the lateral Side tabs with "tension" on the outer contour of the Containers fit and thereby a particularly safe Ensure re packaging.

Another useful embodiment of the fiction moderate packaging material cutting is known records that the upper and lower side flaps in folded state between the containers and the side side flaps are arranged and the inside edge of the folding surface against the associated side Supports side flap. The side side flaps are consequently arranged on the outside.

An additional fixation of the containers within the Packaging is achieved in that in the corner area Chen the blank openings are provided, the Openings in the folded state of the blank one Section of the top and / or bottom of each Release the container. The folding surface is here Lich formed as a web.

The folding surface regularly comprises two fold lines, wel che with the adjacent side tabs connect. However, the folding surface can expediently also more than two fold lines, preferably three fold lines have lines.  

To optimally adapt to the round contour of the Ensuring the outside of the containers is further According to the invention provided that the side tenlaschen over a plurality of bending grooves or Kink grooves with the associated side walls in verbin stand. These bending or kinking grooves are located in the area of the curved outer contour of the in the corner range from the multiple arrangement containers.

The bending or kinking grooves preferably run pa parallel to each other. Conveniently, between four to ten kink grooves per side flap are provided be.

Furthermore, according to an expedient embodiment the present invention in the folded blank in Additional head and / or bottom area of the containers Inclined surfaces can be provided, creating the side walls and / or side areas to the top and / or to the Taper over the floor parts. Next to the thereby achieved particularly attractive design especially in connection with those already described Openings a high packing density of the containers in within the packaging and therefore high packaging stability guaranteed.

To be able to carry the packaging easily, is on a carrying device in a side region of the blank intended. Especially for packaging with one high number of containers housed therein die cuts in the upper part of the packaging material are sufficient rial cutting no longer to an adequate stretcher to ensure safety.  

Expediently on one side as a carrying device Cut in the two side side tabs handle openings provided. The purpose for optimal stacking moderately tight side flaps can be subtracted from the user, creating the two Handle openings become accessible. The consumer has so that a handle is available in a matter of seconds and can take the entire pack on one side area and carry it upright.

The side flaps are expediently complete or individually connected to each other by glue points. This connection method enables one by hand feeding easy opening of the side flaps.

Another useful embodiment of the fiction moderate cut ensures the possibility of opening nens the packaging, but the packaging in particular especially used for transporting the containers can be. This configuration is known records that the folded cut by user opening a tear line on the side can be opened, the folded blank in such a condition remains that the containers contained therein continue can be transported safely. The packaging should therefore also be their actual after opening Function as a means of transporting or storing several Do not lose containers.

A practical embodiment is characterized by this from that from the center of the top to the outside a tear-off area is provided, whereby between the two tear-off areas, a web on the upper part remains. Become the tear-off areas of the blank removed, the containers can be removed easily  will. However, a hand-shaped bridge remains handles so that the packaging is like a "basket chen "is to be handled.

Characterized in that the web preferably over after kink lines has foldable edges at the bottom and / or inside, is an additional stabilization of the handle against an unforeseen tearing ensured. The Carrier also ensures the advantage that the packaging as a storage container for empties and / or as a means of transport for empties back to Supermarket or for glass or metal containers can be used. The containers can the Ver Pack removed immediately, emptied and then be pushed back into the packaging. The Ver packaging thus relieves everyone's waste disposal Household. The invention therefore also carries an essential contribution to environmental protection.

It is further provided according to the invention that the since Lichen side plates in several parts, preferably in two parts are trained and the two sub-areas of each side flap over a fold line and / or a Folded surface are connected. Those trained in this way Side tabs are able to fit snugly on containers with tapering outer contours (e.g. Bottles) because of the kink line or Folding surface of the upper part of the side flap rela tapering towards the lower part towards the top runs. If a folding surface is used, this is between the two sections of the respective side Chen side flap fully folded. Both Ausge designs allow bottlenecks to be as narrow and tight as possible tightly wrapped around.  

In order to achieve the best possible curvature in both the upper, as well as in the lower part of the respective side to achieve chen side flap, the bending or Creases in the part of the upper part respective side tab at an acute angle (one on top of the other to) towards the top. This creates an outer contour of the upper portion of the side flap, which corresponds to a cone section. This cone section shaped section goes in the straight line, d. H. cylin The lower section, which runs in the shape of.

A particularly simple removal of the containers simultaneous maintenance of transportation possible speed is achieved in that the tear-off area Part of the respective side wall and this part associated side tabs.

Another embodiment of the Ver Packing material blank is characterized in that the bottom parts only after covering the containers connected to each other, in particular glued together will. Here, the cut around the Be relationships, then the bottom parts of the same glued together and then the sides flaps folded accordingly and with each other or at least the two outer side flaps preferably connected with glue points. In this case the packaging machine becomes a single-layer mate rial cutting fed.

Alternatively, according to a further embodiment of the blank according to the invention provided that the Floor parts already connected to each other in advance, preferably are glued together. Here the Ver packaging machine already a double layer Ver  Packing material cut in the form of a tunnel-like Tube fed. The containers are then in spent the tube and then the side tabs folded accordingly and provided with glue dots or glued. Such pre-bonding is particularly to be carried out especially with large containers, as a result of this mechanical packaging is made considerably easier.

In the following, expedient refinements of the invention Packaging material blank with reference explained in more detail on the drawings. It shows

Fig. 8 shows the blank according to FIG. 7 in a folded state with removed front stall region.

Reference number 1 in FIG. 1 denotes the packaging material blank in its entirety. The blank 1 is shown in one dimension in FIG. 1, ie it is in the unfolded state. The blank 1 comprises an upper part 2 , adjoining side walls 3 and 3 ' and with the side walls connected bottom parts 4, 4' , which are connected to each other before packaging or immediately during packaging.

The blank 1 is suitable for incorporating a plurality of containers (not shown), for example six lemonade cans or the like, over the four main side surfaces of the can arrangement. To avoid falling out of the containers from the side areas of the blank 1 side flaps 5-9 and 5'-9 'are provided, which (starting from the finished packaging) are divided into upper side flaps 5, 5' , lower side flaps 8, 8 ' and 9, 9 ' and side side plates 6, 6' and 7, 7 ' .

The individual side flaps are each connected to the associated, adjacent side flap via a folding surface 12 (cf. hatched area) and folding lines 10 and 11 .

Furthermore, at the locations of the blank 1 , which are assigned to the top and / or bottom region of the containers, additional inclined surfaces 15 in the form of kinked surfaces are provided, as a result of which the side walls 3, 3 ' and the side regions to the top part 2 and to the bottom parts 4, 4 ' each taper in the folded state and adapt to the upper and lower parts of the containers. These additional inclined surfaces 15 are formed by two circumferential fold lines 26, 29 .

For a particularly tight looping of round containers, for example cans, the side side flaps 6, 6 ' and 7, 7' are connected to the associated side walls 3 and 3 ' via a plurality, ie a plurality of bending grooves or kink grooves 14 . These bending or kinking grooves 14 facilitate the curvature of the side wall or side flap in question.

Furthermore, openings 13 and 13 'are provided in the corner regions of the blank 1 , which release a portion of the top and bottom of the respective containers in the folded state of the blank 1 . The folding surface 12 is thereby designed as a web.

In order to be able to carry the finished packaging without problems, two handle openings 24 are formed in the upper part 2 .

In FIG. 1, for the sake of clarity, only one folding surface is provided with the relevant reference symbols.

During the packaging of the containers, the arrangement of the containers is first enveloped by the main surfaces of the blank 1 and then the bottom parts 4 and 4 ' are connected to each other, preferably glued. Then - as shown in Fig. 2 - the upper side flaps 5, 5 ' and the lower side flaps 8, 8', 9, 9 ' folded down or up, the respective folding surfaces 12 buckling at their fold lines 10 and 11 . For the sake of clarity, the lateral side flap 6 is still shown in the open state in FIG. 2, the two folding surfaces 12 which become effective (see hatching) being visible. The remaining side flaps 5, 5 ' and 7 are already in the fully folded state. Fig lateral side flaps are then mutandis. 3 folded over and under full folding in the folding surfaces 12 joined together, preferably glued. If the blank is completely folded in the side area, the respective folding surfaces 12 rest on the inner sides of the associated lateral side flaps 6, 7 . For a better understanding, the hidden folding surfaces 12 and areas of the upper and lower side flaps 5 and 5 'are shown hatched or dash-dotted lines in the right half of the illustration of FIG. 3. For particularly large and thus heavy arrangements of containers can be used as an alternative to the above packaging method to connect the bottom parts 4 and 4 'together in advance, preferably to glue. The resulting double-layer packaging material blank is then pushed manually or automatically in the form of a tube over the arrangement of the containers and the side flaps are folded in the manner already described above.

Due to the folding surfaces 12 , which connect the adjacent side flaps with each other, a kind of support function or tensioning function is ensured, ie the side flaps 6, 6 ' and 7, 7' in FIG. 1 are put under tension when folded down due to this support effect, which means that the respective lateral side flap or the area of the bending or kink grooves 14 fits closely to the outer contour of the containers. Due to the supporting effect of the folding surfaces 12 , the arrangement of the containers is very closely integrated by the blank 1 and under tension.

FIG. 4 shows a further embodiment of the blank 1 according to the invention, which has a carrying device on one side region. This carrying device is realized by two handle openings 16 which are arranged in the lateral side flaps 6 and 7 and which have a foldable flap 30 . Here, the side faces 6, 6 ' and 7, 7 ' are folded in an analogous manner during the manufacture of the packaging via the upper and lower side flaps 5, 5 ' and 8, 8', 9, 9 ' . The side side flaps 6, 6 ' and 7, 7' are - as shown in Fig. 5 - via a glue point 28 and the upper and lower side flaps 5, 5 ' also connected via an additional (not shown) glue point, so that the handle recesses 16 cannot be used in this state. However, the consumer only has to pull off the side flaps, ie to open the glue point 28 , the handle openings 16 can then be reached through and the packaging can be carried upright. The tab 30 in the handle opening 16 , together with the part of the folding surface 12 in question, causes the material in the region of the handle opening 16 to be doubled or tripled. Due to the feature that the handle openings 16 are completely integrated into the packaging when the packaging is folded, ie when the blank 1 is folded, the inventive blanks can be stored very tightly and therefore very well in the folded state.

For a better understanding of the manner of folding the blank 1 according to the invention, Fig. 6 shows the side area of the blank with three folded side flaps 5, 5 ' and 7 and a non-folded side flap 6 , the folding surfaces 12 of the side flap 6 hatched here are shown.

If the two side side plates 6 and 7 are subtracted from the consumer, the connection from the upper side plate 5 to the lower side plate 5 ' remains effective. The consumer folds the respective tab 30 of the associated handle opening inwards, reaches through the two handle openings 16 and can thus carry the packaging upright without effectively reducing the stability of the packaging.

On the other hand - if necessary - due to the supporting action of the folding surface 12, the lateral side flaps 6, 6 ' and 7, 7' can be connected or glued to each other in the region of their ends at a certain distance from the upper and lower side flaps, as a result of which the handle recesses 16 directly " are accessible ". Secure packaging is ensured here due to the supporting action of the folding surfaces 12 , which causes the inner side flap 5, 5 ', 8, 8', 9, 9 'to bear tightly against the containers.

The recesses 25 in the folding surfaces 12 (see FIG. 4) prevent the handle openings 16 from being closed by the folding surface 12 when the blank 1 is folded.

Fig. 7 shows a further embodiment of the blank 1 of the invention, which can be manually opened in the folded state, the folded blank 1, however, remains in such a state that the containers contained therein continue safely stored and / or can be transported. For this purpose, a tear-off area 20 or 20 'is provided running from the center of the upper part 2 to the outside. Between the two tear-off areas 20, 20 ' only one web 18 remains in the area of the upper part 2 .

The respective tear-off areas 20 and 20 ' are each formed by a tear line 19 or 19' in the form of a perforation line in the packaging material.

By removing the tear-off areas 20 and 20 ' , a type of "basket" is created, from which the containers can be removed in a simple manner, but which, due to the web 18 , which acts as a handle, ensures that the containers are transported further within the packaging.

In order to increase the security against tearing of the web 18 , the web 18 has edges 17 which can be folded downwards via folding lines 22, 23 .

The lateral side flaps 6, 6 ' and 7, 7' are formed in two parts in this embodiment, the two partial areas of the respective side flap being connected to one another via a folding surface 21 . The folding surface 21 enables the setting of a certain inclination of the partial area of the lateral side flaps 6, 6 ' and 7, 7' which is directly connected to the upper part 2 . The folding surface 21 is folded in when the side flaps are folded on the side region of the blank 1 between the upper and lower partial regions of the respective side side flaps 6 and 7 .

In addition, the bending or kink grooves 14 in the upper part 2 assigned portion of the respective side plate 6, 6 ' and 7, 7' towards each other at an acute angle to the opening 13 in the upper part 2 . The latter measures ensure the possibility of creating packaging which, in the form of bottles, can fit very closely to the bottle necks.

The folding surface 12 shown in FIG. 7 has, in addition to the fold lines 10 and 11, an additional fold line 26 .

As can be seen from Fig. 7, the tear-off surface 20 and 20 ' comprises the two folding surfaces which are assigned to the respective upper side flap 5 and 5' and the two parts of the respective side flap 6, 6 ' and 7 assigned to the upper part 2 , 7 ′ . If the tear-off area in question 20 or 20 'is removed, the bottles can be removed as if from a basket, but the packaging can still be used for transport.

FIG. 8 shows the above-described configuration of the blank 1 , which is completely folded and contains containers in the form of a double-row arrangement of bottles 31 , the front tear-off area 20 having already been removed. The bottles 31 can therefore be easily removed from the packaging. This also and precisely because the tear-off area includes not only the upper part 2 , but also the two side parts 3 and 3 ' and the associated side plates 5 (and at least partially 6 and 7 ). In the same way, as shown in Fig. 8, the rear tear-off area 20 'can be removed, a type of basket with a handle in the form of the web 8 is created.

In order to ensure a certain tapering of the side walls upwards in accordance with the tapering of the upper partial area of the side pools 6, 6 ', 7, 7' , the side walls 3, 3 ' also have a kink line 27 .

The invention offers a particularly effective possibility for effective packaging of multiple arrangements of containers with very high packaging quality and thus packaging security and the possibility the use of automatic packaging equipment. The invention therefore represents an essential enrichment in the field of packaging technology.
