Description

BLANK FOR FORMING A PACKAGE, AND A PACKAGE FORMED OF SUCH BLANK

Field of the invention

The invention relates to a blank for forming a package.

The invention also relates to a package formed from such a blank.

Background art

When designing a package, it is often desirous to take into account a number of different design criteria. The package should e.g., often be designed such that it makes efficient use of the material, is easy to transport to the point of use, is easy to prepare for use, and provides a strong structure. It is often desirable that it is strong during handling and stable in an erected state. Moreover, it should often be capable of being erected into a box with a lid and to be used as a box with a lid without the use of any adhesive or similar means of keeping the erected and/or closed, or at least with a minimum use of such adhesive or similar means.

When designing a package being a box with a lid, it is often desirous that the package can be closed in a simple manner in an erected state. When designing packages of a smaller size it is typically desirous to consider also other aspects, such as that it should be easy to stack on shelves in the stores.

Packages made from cardboard are beneficial since they do not take up much space before they are erected, during for example transport. There exist numerous attempts to address the above design criteria in connection to designing a package of cardboard material.

EP2174877 B1 for instance discloses a box and a single blank for forming such box. The blank comprises an outer lid panel and an inner lid panel, wherein parts of the inner lid panel can be removed. The inner lid panel is connected to a first flap which is glued to an inside of a rear wall of the box to form a closed box. The outer lid panel is in turn connected to a second flap which is glued to an outside of a front wall of the box. Further, the document discloses a locking mechanism for the outer lid panel allowing the box to be reclosed after initial opening.

However, it may be noted that the prior art document does not adequately address the set of design criteria that the package should make efficient use of the material, be formed of one single blank, be easy to erect, be closed in a simple manner in the erected state and provide a strong structure, while being capable of being erected into a box with a lid and used as a box with a lid without the use of any adhesive or any similar means of keeping the box erected and/or closed, or at least with minimum use of such adhesive or similar means, while also being easy to stack.
