Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIGS. 1 and 2 are plan views illustrating a secondary packaging according to a first embodiment.

(2) FIG. 3 is a plan view showing a number of primary packages arranged in a secondary packaging according to the first embodiment.

(3) FIG. 4 is a side view of the arrangement of FIG. 3.

DETAILED DESCRIPTION

(4) 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.

(5) 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.

(6) 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.

(7) 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.

(8) 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.

(9) 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.

(10) 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.

(11) 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.

(12) 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.

(13) 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.
