Abstract: This invention relates to an aseptic recipient or bottle containing a non-pasty product, comprising a body with a cylindrical or prismatic lateral wall, obturated at one end by a bottom and presenting an outlet orifice for evacuation of the product, and an internal mobile piston rubbing in tight manner against the inner surface of the lateral wall of the recipient and defining a volume containing the product. In order to prevent the germs and bacteria present in the ambient air from penetrating inside the product and contaminating it, structure is provided for exerting on the piston, upon each use, a sufficient force to push the piston in the direction of the outlet orifice and consequently for exerting on the product a pressure ensuring that the desired quantity of product is evacuated, and non-return structure maintains the piston, after the force exerted to evacuate the product has stopped, in the position attained so as to conserve a permanent residual pressure in the product.
