Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to secondary packaging, i.e. packaging used in order to contain packaging containers during transport or storage. 
       TECHNICAL BACKGROUND 
       [0002]    When a product is packaged in packaging containers for further delivery within a value chain it is common practice to arrange the packaging containers in some sort of secondary packaging. This secondary packaging may consist of a cardboard box, a tray, a dispenser box or simply a plastic bag. 
         [0003]    The present disclosure relates to secondary packaging particularly well suited to contain packaging containers in the form of bottles or bottle like packaging containers. The bottles may be regular plastic bottles, glass bottles or carton bottles, referred to as “primary packages”. “Carton bottles” may be used to describe a packaging container having the overall appearance of a bottle, yet being made fully of cardboard, or a fusion between a cardboard sleeve and a plastic top comprising an opening device. Two examples of the latter would be Tetra Top™ and Tetra Evero Aseptic™ by the present applicant. 
         [0004]    One type of secondary packaging uses a tray in which a base end of the primary packages is arranged, and an insert localizing a top end of the packages. 
         [0005]    The present disclosure relates to an improved secondary packaging of using a tray and insert 
       SUMMARY 
       [0006]    According to a first aspect the present invention provides a secondary packaging comprising a tray for localizing a base end of primary packages and an insert for localizing a top end of primary packages, characterized in that the insert is punched. 
         [0007]    In one or more embodiments the insert further comprises recesses for improved localization of the top end of the primary packages, preferably one recess for each primary package. 
         [0008]    In one or several embodiments the insert further comprises tabs for localisation of the insert in relation to a top end of the primary packages. Each tab has one end pivotally attached to the insert and a free end. 
         [0009]    In one or more embodiment the tab is formed in one piece with the insert. 
         [0010]    In one or more related embodiments the tabs are configured to be arranged in a position normal to a main surface of the insert. In this way, if the tabs are bent towards the top of the primary packages the extension of the tabs may be used to align the insert in relation to the very top end of the packages. The bent tabs may also increase the contact area between the insert and the primary packages thus improving the distribution of any load. 
         [0011]    In any embodiment the secondary packaging may be complimented with a wrap, such as a shrink wrap, ensuring the integrity of the secondary packaging. The wrap will also align the free end of the tab with the top end of a primary package. 
         [0012]    According to another aspect of the present disclosure relates to an insert according to the above or below description is disclosed. The insert may be used in combination with the tray as disclosed or in combination with any other tray, or even without a tray. 
         [0013]    According to still another aspect it is disclosed a method for manufacturing a secondary packaging according to any previous or following description. In particular such a method may include the step of punching an insert from a tray. The method may also comprise punching the tray from a larger piece of material, as well as folding the sides of the tray to make it more adapted to localize and protect the base end of primary packages arranged therein. 
         [0014]    A secondary packaging comprising a tray and an insert, wherein the tray is configured to localize a lower end of primary packages and the insert is configured to localize an upper end of the primary packages, wherein the insert is formed from cutout material of the tray. 
         [0015]    The insert may comprise recesses for localizing an upper end of the primary packages. 
         [0016]    The insert may comprise tabs formed in one piece with the insert, wherein the tabs has a free end and are pivotally associated with the insert. 
         [0017]    The tabs may be arranged in recesses for localizing an upper end of the primary packages. 
         [0018]    The tabs may be positioned to, in a use position, engage the primary packages. 
         [0019]    The tabs may be positioned to engage a neck or an opening device of the primary packages. 
         [0020]    An insert for use in a secondary packaging may comprise recesses for localizing an upper end of primary packages and pivotable tabs for localizing the insert in relation to the upper end of the primary packages. 
         [0021]    According to another aspect the disclosure relates to a method for manufacturing a secondary packaging having a tray for localizing a lower end of primary packages and an insert for localizing an upper end of primary packages, said method comprising: providing a piece of raw material, cutting the insert from the raw material, thus forming a cutout in the raw material, forming the tray from an area of the raw material comprising the cutout. 
         [0022]    According to one or more embodiments the insert may be maintained positioned in the cutout of the tray in a transportation step, for later separation. 
         [0023]    In one or more embodiments the insert may be separated from the tray, either before or after having transported the secondary packaging to a location in which it will be used for its ultimate purpose.

     DETAILED DESCRIPTION 
       [0027]      FIG. 1  illustrates a first embodiment of the present invention, in a schematic, yet clear manner. A piece of raw material  100 , such as a rectangle made from cardboard, is used as a starting point during the manufacture of the secondary packaging of the present embodiment. An insert  200  is punched out from the raw material  100 , effectively dividing it into the insert  200  and a tray, also designated with the reference numeral  100 . To punch the shape with a knife or stamp is one option available to the skilled person, yet there are numerous other ways to cut out shapes in a material such as cardboard. The present invention should therefore not be limited to a single cutting method, and the present disclosure does not relate to novel methods of cutting cardboard but to a particular secondary packaging. 
         [0028]    In the present embodiment the tray  100  is provided with sub panels,  102 ,  104 ,  106 ,  108 , which may be separated from a main body of the tray  100  by means of creasing lines or “weakening lines” indicated by dotted lines in  FIG. 1 . The wakening lines may be accomplished by pressing or deforming the material locally in a manner commonly used in manufacture of cardboard boxes of various types. The sub panels  106  and  108  are also provided with creasing lines and cuts (the latter indicated by full lines) separating them from the neighbouring panels  102 ,  104 . This arrangement makes it easy to fold the sub panels to a standing position, normal to the plane of the main body, thus forming sidewalls of the tray  100 . The cuts and creases may instead be arranged in the panels  102 ,  104  and in other embodiments it is enough with creasing lines to form the sidewalls. In still other embodiments the sidewalls may be left out, leaving the main body of the tray only. The sidewalls may be secured in a raised state by means of an adhesive such as a hotmelt, yet they may also be forced and maintained in a raised state by a wrap arranged around the secondary packaging once the primary packages are arranged therein. One example of such wrap may be a shrink wrap or other plastic commonly used in relation to secondary packaging. 
         [0029]    Turning to the insert  200 , it may be described as having a rectangular shape in a central body  202  and being provided with recesses  204  or cutouts. A purpose of the recesses  204  is to localize or position the neck of a primary package, such as the neck of a bottle. In one or more of the recesses  204 , preferably though not necessarily all, a tab  206  is arranged. The tab  206  is readily formed during the manufacturing process. Each tab  206  has a free end and a weakening line may be arranged at the end which is connected to the central body  202 . For the sake of simplicity it is preferred that the tabs  206  are formed in the same piece with the central body  202 . The weakening line, also indicated by a dotted line, helps the tab  206  to pivot, and though it is not absolutely crucial it does add to the functionality of the tab  206 , and as such it ensures a reliable function. A length of the tab  206  is defined as the extension from the free end to the pivot axis (the weakening line if there is one). The length of the tabs  206 , as will be explained in relation to  FIGS. 3 and 4 , will have a beneficial effect. The insert as described above and below may be used without the tray  100 , since it does have functional advantages beyond the beneficial effect of saving raw material. The particular location of the tabs as illustrated in the drawings also has the effect that the tabs are located as close to the centre of the central body as possibly, thus minimizing torsion effects. 
         [0030]    In  FIG. 2  it is indicated how the insert  100  is lifted from the tray  200 . The secondary package will be used when arranging the primary packages therein, i.e. after filling of the primary packages. The manufacture of the secondary packaging may be performed in close proximity of where it will be used, yet it may also be performed at another site, if that is considered more efficient. 
         [0031]      FIG. 3  is a plan view of six primary packages  300  arranged in a secondary packaging comprising a tray  100  and an insert  200 . The primary packages comprise a shoulder portion  302  and an opening device  304 . After having arranged the primary packages  300  in the tray  100 , or at least having arranged them in a similar configuration, the insert  200  is pressed down between the primary packages  300  by means of a relative motion. When doing this the tabs  206  will fold upwards. When doing so they may act as a positioning means for the insert in relation to the top of the primary packages  300 . The shape of the primary packages  300  may prevent the insert  200  from sliding downwards, and in combination with the tabs  206  the insert  200  will be localized with great precision such that the insert  200  may fulfil its ultimate purpose of localizing the primary packages such as to protect them from damage during transportation and storage.  FIG. 3  contains more reference numerals than what has been referred to here, yet for those reference numerals reference is made to  FIGS. 1 and 2 . 
         [0032]      FIG. 4  is a sideview of the arrangement of  FIG. 3 . The primary packages  300  are shown as carton bottles, having an opening device  304 , a shoulder portion  302  made from plastic and a body portion  306  formed from a packaging laminate based on a paper core with plastic layers laminated thereto. This is merely an example, and it is apparent that present secondary packaging may be used for other containers such as bottles made from plastic, PET, glass, etc. The tray  100  will in this example localize the primary packages both by restricting their motion in a lateral direction and of course by aligning the bottom of the primary packages since they are all resting on the tray. In other embodiment only one of the localization effects may be utilized, and in still other embodiments where the tray is omitted the localization effect may be accomplished by other means, for example by a shrink wrap. 
         [0033]    In the view of  FIG. 4  a wrap, such as a shrink wrap  400  is indicated. This shrink wrap  400  will localise the free end of the tabs  206  and thereby the insert  200  as such. The same effect could be accomplished by arranging a further tray  100  on top of the first one, or by arranging the primary packages  300  in a cardboard box (not shown) with a closed lid, etc. This highlights that for the present secondary packaging the insert  200  does not necessarily have to be used in combination with the tray, although the disclosed way of manufacturing the insert from the tray still is beneficial. 
         [0034]    A suitable material for the secondary packaging is cardboard or any similar material, and for the wrap any material commonly used as shrink wrap may be used. 
         [0035]    It should be appreciated that the present disclosure has the purpose of explaining a few examples of the present invention in order to enable for the skilled person to practise it within the full scope. The fact that not all possible embodiments and uses have not been disclosed should not be interpreted as limiting for the scope of the present disclosure as defined only by the claims in the form they may have. For example, the disclosed position of the tabs results in a number of effects. This does not remove the fact that one or more tabs arranged at other positions, instead or in combination with the original tabs, may result in part of the same effects. The fact that cardboard is the only material explicitly mentioned does not remove the possibilities of using other materials having suitable properties. “Suitable properties” may in this respect refer to rigidity, stiffness, durability, cost, etc. Furthermore, the drawings only illustrate an example with six primary packages, yet it does not exclude examples having 3, 4, 5, 6, 7, 8, 9 . . . etc primary packages from the scope of the claims. 
         [0036]    Additionally, although individual features may be included in different claims, these may possibly advantageously be combined, and the inclusion in different claims does not imply that a combination of features is not feasible and/or advantageous. In addition, singular references do not exclude a plurality. The terms “a”, “an”, “first”, “second” etc do not preclude a plurality. Reference signs in the claims are provided merely as a clarifying example and shall not be construed as limiting the scope of the claims in any way.
