Detailed description of the invention

[0007] Figure 1 shows a carrying device which does not form a part of of the invention, which is arranged for forming a multipackage containing two cartons. Figure 2 shows two cartons 31 placed side by side, the carrying device of Figure 1 being arranged to receive said two cartons 31 so as to form a multipackage. Figure 3 shows a multipackage formed from the carrying device of Figure 1 and the cartons of Figure 2.

[0008] The carrying device comprises a frame 2 which is arranged, in use, to surround peripherally an upper part of the cartons 31 of the multipackage when the cartons 31 are placed side by side. In a use situation, the frame 2 resides tightly against the cartons 31 in a lateral direction. The frame 2 is provided with supporting means and carrying means. The supporting means are arranged, in use, to apply supporting forces to each carton 31 of the multipackage to enable carrying. The carrying means are arranged to enable a user to take hold of the multipackage in order to carry the multipackage.

[0009] For each carton 31 to be included in the multipackage, the supporting means comprise a tongue 6 at an upper part of the frame 2 as well as a lateral supporting section 8 at a lower part of the frame 2. Each tongue 6 is arranged, in use, to apply a vertical supporting force to a recess 35 located at the upper part of the carton 31, and each lateral supporting section 8 is arranged, in use, to apply a lateral supporting force to the carton 31, below the recess 35.

[0010] It can be seen in Figure 4, which shows a cross section of the multipackage of Figure 3, how the tongue 6 penetrates into the recess 35. The vertical supporting force applied by each tongue 6 is designated by arrow 65, while the lateral supporting force applied by each lateral supporting section 8 is designated by arrow 85.

[0011] Each tongue 6 is an integral part of the frame 2, in a use situation projecting obliquely from a side wall of the frame 2 with which it is associated. Each tongue 6 is associated with the frame 2 through a crease 62 which is arranged to turn the tongue 6 inwards with respect to the part of the frame 2 with which the tongue 6 is associated. One such crease is shown in Figure 5 wherein a bending force generated by the crease is designated by arrow 95.

[0012] Each lateral supporting section 8 is an integral part of the frame 2. Each lateral supporting section 8 is formed by a part of a straight side wall of the frame 2 located below an adjacent tongue 6 while the lateral supporting section 8 is located on the same side of the frame 2 as the adjacent tongue 6.

[0013] The carrying means comprises two carrying holes 12 provided in the frame 2, each being arranged to receive, at least partly, at least one finger of the user for carrying the multipackage. The carrying holes 12 are located on opposite sides of the frame 2, these opposite sides being perpendicular to each side of the frame 2 which comprises a tongue 6.

[0014] The carrying device of Figure 1 further comprises a top wall 14 provided with an information aperture 16. When forming the multipackage, the information aperture 16 is arranged to allow a top 33 of each carton 31 of the multipackage to penetrate through the top wall 14 such that in a use situation a "best before" date provided at the top 33 of each carton 31 is readable.

[0015] The information aperture 16 divides the top wall 14 into two parts, each part being associated with an adjacent side wall containing a carrying hole 12 via a crease 72. Further, each part of the top wall 14 is associated with an adjacent side wall, containing a tongue 6, in order to stiffen the carrying device. A side wall containing a tongue can be provided with a projection which, when manufacturing the carrying device, is bent so as to be parallel with the top wall and glued thereto.

[0016] The top wall 14 is provided with two cap openings 18, each being arranged to receive a cap 37 of the respective carton 31. The cap openings 18 enable the top wall 14, which extends perpendicularly to the side walls of the frame 2 and which, in a use situation, thus extends horizontally, to be located lower than upper parts of the caps 37.

[0017] The carrying device may not comprise a top wall. In such a case, it is naturally to be ensured that the side walls containing a carrying hole are strong enough to withstand stresses caused by carrying of the multipackage.

[0018] The carrying device shown in Figure 1 is arranged for forming a multipackage from cartons whose cross section below the recess has the shape of a rectangular parallelogram. To be more precise, the shape of the cross section of the cartons 31 of the multipackage of Figure 3 below the recess 35 is that of a square. The carrying device may also be arranged for forming a multipackage from cartons whose cross section below the recess has the shape other than that of a rectangular parallelogram.

[0019] The multipackage of Figure 3 contains two cartons. The carrying device according to the invention may also be arranged for binding more cartons to one another so as to enable them to be carried together. For instance, a carrying device for a four-carton multipackage is obtained by keeping the dimensions of the side walls containing a carrying hole as before and by enhancing the dimensions of the side walls perpendicular thereto so as to correspond with two adjacent cartons. In such a case, each side wall perpendicular to the side walls containing a carrying hole is thus provided with at least one tongue for each carton located on the side in question, said at least one tongue being arranged, in use, to apply a vertical supporting force to the recess located at the upper part of the respective carton.

[0020] The relative expressions used in the above disclosure, such as "at the upper part of the carton", "at the upper part of the frame" and "below the recess", refer to a normal use situation wherein the multipackage is in the vertical position according to Figure 3. In the multipackage of Figure 3, the caps 37 of the cartons 31 reside at the upper part of the multipackage, as do the carrying holes 12.

[0021] Figure 6 shows a carrying device according to an embodiment of the invention. In the carrying device of Figure 6, a tongue 6' is an integral part of a frame 2', in a use situation projecting obliquely inwards from the side wall of the frame 2' with which it is associated. Each tongue 6' is associated with the frame 2' through a crease 62' which is arranged to turn the tongue 6' inwards with respect to the part of the frame 2' with which the tongue 6' is associated. The crease 62' is positioned in a lower edge of the tongue 6'. The crease 62' is curved such that a middle part of the crease 62' resides lower than ends of the crease 62'. An imaginary line passing through the ends of the crease 62' is horizontal. Since the crease 62' defines the lower edge of a tongue, the lower edge of the tongue 6' is curved.

[0022] The tongue 6' further comprises a middle crease 64' which extends from a tip of the tongue 6' to the lower edge and which is arranged to turn the middle part of the tongue 6' inwards with respect to edge parts of the tongue 6', making the tongue a concave groove.

[0023] Figure 7 shows a carrying device according to a second embodiment of the invention, which is arranged for forming a multipackage containing three cartons. The carrying device of Figure 7 differs from the carrying devices of Figures 1 and 6 also in that in the carrying device of Figure 7, tongues 6" are positioned on long sides of a frame 2", i.e. two tongues 6" are provided per each carton to be received, i.e. six tongues in total.

[0024] Each tongue 6" is associated with the frame 2" through a crease 62". The crease 62" is positioned in a lower edge of the tongue 6". Each crease 62" has the shape of a wide V such that a middle part of the crease 62" resides lower than ends of the crease 62". An imaginary line passing through the ends of the crease 62' is horizontal. Each tongue 6" comprises a middle crease 64" which extends from a tip of the tongue 6" to the lower edge and which is arranged to turn the middle part of the tongue 6" inwards with respect to edge parts of the tongue 6", making the tongue a concave groove. Each tongue 6" is symmetrical in respect of its middle crease 64".

[0025] Figure 8 shows a multipackage formed by using a carrying device which does not form a part of the invention. In the carrying device of Figure 8, a tongue 6"' is an integral part of a frame 2"'. The tongue 6"' is associated with the frame 2"' through a crease 62"' which is arranged to turn the tongue 6"' inwards with respect to the part of the frame 2"' with which the tongue 6"' is associated. The crease 62"' is positioned in a side edge of the tongue 6"'. Thus, the crease 62"' extends in a vertical direction. The height of the tongue 6"' in its outermost part is smaller than in a part adjacent to the crease 62"'. An upper edge of the tongue 6"' comprises a horizontal section next to the crease 62"', and an inclined part at a distance from the crease 62"', the inclined part of the upper edge sloping downwards, i.e. the lowest point of the inclined part of the upper part is located at an end that is far from the crease 62"'. A lower edge of the tongue 6"' is upwardly inclined, the lower edge rising upwards as the distance from the crease 62"' grows.

[0026] In the carrying devices according to the invention, each tongue is associated with the frame at one of its edges only. The rest of the edges of the tongue are clear of the frame part.

[0027] The top walls of the carrying devices of Figures 6 to 8 are provided with information apertures but do not comprise cap openings. When necessary, however, said carrying devices may be provided with cap openings. The carrying device according to the invention may be made e.g. from cardboard, corrugated board, plastic material or a combination thereof. The carrying device may be manufactured from a sheet-like initial preform, which is first provided with necessary perforations and creases, after which the perforated and creased initial preform is folded into its final shape and glued together.

[0028] It is apparent to one skilled in the art that the basic idea of the invention may be implemented in many different ways. The invention and its embodiments are thus not restricted to the above-described examples but may vary within the scope of the claims.
