An apparatus for prewarming tooth paste in a tooth paste tube prior to extrusion from the tube through an outlet opening in the end of the tube includes a cap-shaped member of plastic material detachably closing the opening and enveloping the outlet end of the tooth paste tube. The cap-shaped member has an outer skirt portion extending along and surrounding portion of the side wall of the tube adjacent the outlet opening and an electrical resistance heating element is embedded in the cap-shaped member including the outer skirt thereof for warming the outlet section of the tube when the terminals of the heating element are connected to an electrical power source while the tube is closed by the cap-shaped member. A thermostat unit embedded in the cap-shaped member is connected in series with the heating element to control the temperature to which the outlet section of the tube is heated. The electrical terminals are formed in a rigid electrical plug at a stiff area on the cap-shaped member for direct insertion into an electric wall socket as well as for hanging the apparatus thereby.
