Embodiment Construction
[0098] The invention will be described hereinafter with reference to an embodiment of the invention, which is also shown in the accompanying drawings.
[0099] Figure 1a schematically shows a packaging structure 1 designed according to the principles of the present invention. The packaging structure 1 defines a top surface 2, a bottom surface 3 (not visible in FIG. is visible in . The side panels 4a, 4b extend from the bottom surface 3 to the top surface 2 . In this way, the packaging structure 1 can form a closed structure enclosing the inner space. Figure 1a shows the packaging structure 1 in an upright position, in which an item has been (or is intended to be) filled.
[0100] FIG. 1 b schematically shows a raw blank 5 for forming the packaging structure 1 . The blank 5 is suitably formed to comprise two flaps 2a, 2b which can be folded to form the above-mentioned top surface 2 when the structure 1 is in its assembled state. Likewise, said blank 5 comprises two further...

Abstract
The invention relates to a packaging structure (1) formed from a multilayer sheet (6) comprising an intermediate layer (8), a first outer layer (7) attached to said intermediate layer (8) ), and a second outer layer (9) attached to the middle layer (8), the packaging structure (1) defines a bottom surface (3), a top surface (2) and joins the bottom surface (3) and The top surface (2) has a plurality of side panels (4) forming a closed structure, wherein at least one edge (14) is defined between adjacent side panels (4). The invention is arranged such that said second outer layer (9) has a lower bending stiffness according to ISO5628 than said first outer layer (7), so that said plate (6) is only ) is outwardly bendable in a direction towards, and the packaging structure (1) is formed such that at least one side panel (4) is curved and / or at least one edge (14) is rounded.
Description
technical field [0001] The present invention relates to a packaging structure formed from a multilayer sheet material comprising a middle layer, a first outer layer attached to the middle layer and a second outer layer attached to the middle layer, the The packaging structure defines a bottom surface, a top surface, and a plurality of side panels joining the bottom surface and the top surface to form an enclosed structure, wherein at least one edge is defined between adjacent side panels. [0002] The invention also relates to a method of manufacturing a packaging structure. Background technique [0003] There is a demand today for packages, cases and casings that are uniquely designed and have graphics that appeal to customers, such as eye-catching packaging forms for sales purposes that are under development. Examples of such packages are cylindrical or oval packages, or packages with rounded sides or edges. [0004] Currently, packaging structures can be manufactured fr...
