Abstract

A safety valve for mounting on the opening of a feeding bottle. The safety valve has an outer cap with a raised flat top in the middle with perforations thereon, and a flanged inner cap with a raised flat top in the middle disposed inside an interior space defined by the side wall and the raised flat top of the outer cap. The inner cap is rotatable with respect to the outer cap from an open position to a closed position. The raised flat top of the inner cap has a plurality of through holes formed thereon which, when in the open position, are in alignment with the perforations formed on the raised flat top of the outer cap to form passages for the milk contained in the feeding bottle to flow therethrough. A plurality of temperature sensitive springs and a regular spring are connected between the outer and inner caps to rotate the inner cap to the closed position when the temperature of the milk is higher than a pre-specified range and to return the inner cap to the open position when the milk is cooled down.
