1. A dispensing system for dispensing fluidic content, said system comprising:
a container comprising a wall with an opening therein, the container defining an interior open volume configured to receive the fluidic content therein; and
a port attached to the opening of the container and configured to be traversed by a needle configured to transfer the fluidic content between an inside of the container and an outside of the container, said port comprising:
a rigid annular member extending in a longitudinal direction, said rigid annular member comprising a side wall surrounding a channel extending in the longitudinal direction between an inner end and an outer end of the rigid annular member and configured to receive the needle, said rigid annular member being open at the inner and outer ends to allow the needle to pass therethrough, and
an overmolding member made of thermoplastic elastomer and disposed around the rigid annular member, the overmolding member comprising
an annular body extending in the longitudinal direction from a proximal end portion affixed to the wall of the container to a distal end portion extending into the open volume of the container, the annular body comprising
an inner surface directly contacting the side wall of the rigid annular member, and
an outer surface having an adhesion portion that directly welds the outer surface at the proximal end portion of the annular body to the wall of the container at the opening, and
a sealing portion integrally formed with the annular body at a lower end thereof, the sealing portion being configured to be traversed by the needle in a direction close to the longitudinal direction and configured to seal the overmolding member in a fluid-tight manner in the absence of the needle after withdrawal of the needle,
wherein the overmolding member is configured to seal the channel in a fluid-tight manner in the absence of the needle after withdrawal of the needle.
