Abstract

Disclosed is an elastic coil member for a pump dispenser, wherein the elastic coil member provides a uniform elastic restoring force to a head part when the head part is pressed toward a container cap by an external force and prevents corrosion thereof and spoiling of contents even in a state where the elastic coil member is in contact with the contents. The disclosed elastic coil member for a pump dispenser includes a first support ring seated in a housing provided at a container cap, a second support ring spaced apart from the first support ring and being pressed against the head part, and a uniform elasticity generation part provided between the first support ring and the second support ring and generating a uniform elastic restoring force when the head part is pressed by an external force.
