Abstract
The invention relates to a reusable plastic bottle for receiving a product, which bottle consists of a plastic material that absorbs odorous molecules from the product or from residues of the product. Coffee additives and/or coffee flavors are added to the plastic material, thereby reducing the penetration of odorous molecules into the plastic and reducing, masking or neutralizing off-odors of the odorous molecules.
