A stopper or closure for a fluid product retaining container constructed for being inserted and securely retained in a portal forming neck of the container, said stopper/closure comprising:A. an elongated, solid, cylindrically shaped member dimensioned for insertion in the portal of the neck of the fluid product retaining container for closing and sealing the fluid product in the container; B. said member being formed from extruded foamed plastic material comprising a density ranging between about 100 kg/m3 to 500 kg/m3 and constructed for sealing the fluid product retained in the container and preventing transfer of the fluid product from the container prior to removal; and C. said foamed plastic material comprises a blend of at least formed two components, each comprising different hues or colors, thereby imparting an integrally formed streaking effect to said synthetic closure; whereby a synthetic closure is attained which is capable of completely sealing any desired fluid product in a container, retaining the product in the container for any desired length of time without any degradation of the fluid product or degradation of the closure, while providing a visual appearance substantially identical to a stopper formed from natural material.
