Abstract: Flower vase made of a watertight, cardboard-like material. Starting from a blank, after fold lines suitably applied have been introduced, a vase is obtained, which is watertight without glue or sealing techniques. In particular it is proposed to design the folding structure such that there are elastic material flaps in the middle of the vase for accommodating a bouquet of flowers closely fitting therein. Because of the folding inwards, a stiff outside of the vase is created. Optional carrying handles, such as cords, can be applied such that this inward-moving effect for retaining a bunch of flowers is reinforced. A vase of this type can be provided with any desired printing and can have any desired dimensions.
