A plastic massage bottle has a neck portion with a mouth opened and closed by a cap, a shoulder portion extending from the neck portion, a bottom portion, and a body portion interconnecting the shoulder portion and the bottom portion. The body portion is formed with a thickness of 0.1 to 0.6mm so that the body portion can be subjected to elastic deformation in the event of the massage bottle being tapped on or pressed against a human body. The body portion includes a plurality of pressure massage protrusions so shaped and arranged that they can make contact with and apply massage pressure to a multiplicity of discrete, adjoining points of the human body as the bottle is tapped on or pressed against the human body. Massage-aiding fluid is partially filled in the bottle for generating kinetic energy in response to the tapping or pressing motion of the bottle.
