Container having a petaloid base with rib feet

Abstract

Disclosed is a plastics container obtained by blow moulding or stretch blow moulding from a blank, this container including a body, a neck which extends at an upper end of the body and a petaloid base which extends at a lower end of the body, this petaloid base being provided with protruding feet that are separated by recessed valleys that extend radially from a central region of the base, each foot having an external wall which extends in continuation of the body and two side walls that each border a valley and are each connected to the external wall by a fillet, each foot being provided with at least one rib, a lateral portion of which overlaps the fillet.
