A packaging arrangement for a product and a sample associated with the product. The packaging includes a flexible tube having a first end which delimits an outlet hole a second end opposite the first which is closed at an end closure zone formed by fastening an end edge portion of the tube onto itself, for example, by welding or adhesive bonding. The tube further includes at least one intermediate closure zone which is formed between the first and second ends, and which is formed by fastening a wall of the tube onto itself along at least one transverse line so as to define at least two compartments which are isolated from one another. One of the compartments communicates with the outlet hole. The two compartments can be separated from one other by breaking (e.g., tearing) an arrangement for facilitating separation, with the separation facilitating arrangement provided in the region of the intermediate closure zone. The product and the sample can be the same or different products.
