Description

BLANK INTENDED TO BE ERECTED INTO A PACKAGE
Field of invention
The invention relates to a blank intended to be erected into a package having protective zones protecting of goods inside the package against mechanical impacts.
Technical Background
Many different types of objects are packaged in packages which are made from a blank, the package being assembled by folding the blank.
Sometimes the package is folded around an object, enclosing the object as the package is assembled of the blank.
The blanks are most often made of a two-dimensional material which is cut, provided with fold lines and then folded.
For such packages, formed form folded two-dimensional blanks, it is a general problem to create them with as little waste material as possible while still being simple and quick to assemble. At the same time such packages generally don’t provide for a satisfactory protection of therein packaged objects against mechanical impacts.
In documents US 3386641 , EP 2594501 and SE 1451055 such blanks are described. Additionally, in these documents the blanks are intended to form packages which comprise portions providing additional protection against mechanical impacts.
