Abstract
The present application deals with a grid flap, comprising a multiplicity of vertical and horizontal grid struts, a frame which surrounds the grid struts, wherein a vertical and a horizontal grid strut respectively overlap in a crossing point, characterized in that the crossing points of the grid struts are made of one piece. As the grid is self-supporting because of its topology (made of one piece) and the overlapping of two grid struts can be avoided, double areas or cavities can be avoided, which contributes to a hygienic design of the grid flap.
