Claim:
Closure with hinged lid for a container having an automatic lid opening system, said closure comprising: a main body, provided with a supply mouth to be applied to a neck of the container; a hinged lid joined to said main body by a hinge joint, so that said lid can pivot between an open position and a hinged position in which the lid blocks said supply mouth, wherein said main body and said lid are molded from a rigid plastics material; an elastic element arranged between said main body and said lid to apply a spring-back force on said lid towards said open position, wherein said elastic element is made from an elastomer material other than said rigid plastics material; an anchoring member between said lid and said main body for retaining said lid in said hinged position; and a button for operating the release of said anchoring member, so that by operating said button the lid is opened due to the action of the spring-back force applied by said elastic element, wherein said elastic element has at least one first joining area fixedly attached to said main body and at least one second joining area fixedly attached to said lid, with at least one extendible section of said elastic element being defined between said first and second joining areas; wherein said main body includes at least one projection that defines a seating surface, said seating surface being positioned externally with respect to said hinge joint; and wherein said extendible section extends freely in front of said seating surface, so that when said lid pivots towards said hinged position said seating surface receives said extendible section, which rests on said seating surface, and keeps said extendible section positioned externally with respect to said hinge joint.
