Inventor(s) include Ammann, Peter.

The application for the patent was published on May 30, under issue no. 22/2025.

According to the abstract released by the Intellectual Property India: "The invention relates to a box (10) having a variable volume and/or shape. The box comprises four box lateral walls (10a) and a box base (10b) with a first, a second, a third, and a fourth element (1, 2, 3, 4). Each element has two lateral walls (1a, 1b; 2a, 2b; 3a, 3b; 4a, 4b) and a base (1c, 2c, 3c, 4c) and is connected to two adjacent elements such that each element forms a corner of the box, wherein the box base (10b) is formed by at least partial overlapping of the bases (1c, 2c, 3c, 4c) of all of the elements, and each box lateral wall (10a) is formed by a lateral wall of one element and a lateral wall of an adjacent element (1b, 2a; 2b, 3a; 3b, 4a; 4b, 1a) such that the lateral walls are pushed into each other. The element lateral walls which are pushed into each other can be moved back-and-forth relative to one another in a longitudinal direction (x; y) of the lateral walls between a minimum overlap position and a maximum overlap position, and the volume and/or shape of the box can be changed by changing the length (L1, l2) of any two opposing box lateral walls (10a) or any two opposing box lateral walls and subsequently the other two opposing box lateral walls. Each box lateral wall is formed by a lateral wall with a longitudinal guide (1a; 1b; 3a; 4a) and a lateral wall without a longitudinal guide (2a; 2b; 3b; 4b) such that the lateral wall without the longitudinal guide can be received in the longitudinal guide (9a) of the lateral wall with the longitudinal guide and can be held therein in such a way that it can be moved back-and-forth."

The patent application was internationally filed on Oct. 21, 2022, under International application No.PCT/EP2022/079373.
