Printing fluid container

A printing fluid container for a printing fluid source for a printer system, the printing fluid container comprising:

• a neck having an outer opening;
• a closure device comprising:
• a closure device main body connected to the neck, the closure device main body comprising a closure device printing fluid outlet opening and a closure device printing fluid outlet passage extending from the outer opening of the neck through the closure device main body to the closure device printing fluid outlet opening;
• and
• a closure device lid connected to the closure device main body, wherein
• the closure device lid comprises a lid member for closing the closure device printing fluid outlet opening, and
• the closure device lid has a first position, in which the lid member closes the closure device printing fluid outlet opening, and a second position, in which the lid member opens the closure device printing fluid outlet opening;
• and
• a sealing material layer disposed within the closure device printing fluid outlet opening of the closure device, the sealing material layer having:
• an initial condition, in which the closure device printing fluid outlet opening is sealed;
• a fluid outlet condition, in which the sealing material layer is pierced by engagement of a fluidic interconnect device of the printing fluid source, which fluidic interconnect device provides a printing fluid inlet passage towards an inner space of the printing fluid source, and the closure device printing fluid outlet opening establishing a fluid path through the closure device printing fluid outlet opening;
• and
• a re-sealing condition, in which the sealing material layer re-seals the closure device printing fluid outlet opening upon removal of the fluidic interconnect device.
