Abstract

A board blank for producing a folding carton, has a base panel having a plurality of sides, a plurality of side panels each hinged to a respective one of the sides of the base panel, a top panel hinged to one of the side panels, and a plurality of intermediate sections each located between and connecting two neighboring ones of the side panels with one another. Each of the intermediate sections is foldable along a folding line which divides each of the intermediate sections into a first part located adjacent to one of the two neighboring side panels and a second part located adjacent to another of the two neighboring side panels. The first part of each of the intermediate sections is provided with a cut-out adjacent to the one neighboring side panel so that the second part of each of the intermediate sections rests against the one neighboring side panel when the intermediate sections are folded.

Claims

1. Board blank for production of a folding carton, with a base, two side panels and also a front panel and a back panel hinged to the base, and a top panel hinged to the back panel, where the panels hinged to the base are connected by intermediate sections, each of which is divided by a folding line, wherein each of the intermediate sections is provided with a cut-out section in an area adjacent to the front panel and the back panel, so that an area of the intermediate sections adjacent to the side panels rests directly against the front panel and the back panel in an area of said cut-out section when the intermediate sections are folded into position against the front panel and the back panel, said cut-out section being substantially rectangular and forming substantially a rectangle with one narrow side abutting against an adjacent one of the front panel and the back panel, the cut-out section having an inner corner facing away from one of the front and back panels and being rounded at a distance from said folding line.

2. Board blank according to claim 1, wherein the cut-out section forms substantially a rectangle, where one narrow side of the rectangle abuts against an adjacent one of the front and back panels, while the cut-out section is located on an outer edge of the intermediate section and is thus open towards outside of the blank.

3. A board blank for producing a folding carton, comprising a base panel having a plurality of sides;

a plurality of side panels each hinged to a respective one of said sides of said base panel;

a top panel hinged to one of said side panels; and

a plurality of intermediate sections each located between and connecting two neighboring ones of said side panels with one another, each of said intermediate sections being foldable along a folding line which divides each of said intermediate sections into a first part located adjacent to one of said two neighboring side panels and a second part located adjacent to another of said two neighboring side panels, said first part of each of said intermediate sections being provided with a cut-out adjacent to said one neighboring side panel so that said second part of each of said intermediate sections rests against said one neighboring side panel when said intermediate sections are folded, said cut-out section being substantially rectangular and forming substantially a rectangle with one narrow side abutting against an adjacent one of the front panel and the back panel, the cut-out section having an inner corner facing away from one of the front and back panels and being rounded at a distance from said folding line.

4. A board blank as defined in claim 3, wherein each of said intermediate sections have an outer edge, said cut-out being formed substantially as a rectangle with a narrow side next to said one neighboring side panel and with a wide side which is open at said outer edge.

5. A board blank as defined in claim 4, wherein each of said cut-outs has another narrow side, another wide side, and a curve between said another narrow side and said another wide side.
