## Abstract

A printing fluid container for a printing fluid source for a printer system, wherein the printing fluid container comprises a sealing material layer being arranged in a closure device printing fluid outlet opening, the sealing material layer having a fluid outlet condition, in which the sealing material layer is pierced by engagement of a fluidic interconnect device of the printing fluid source and the closure device printing fluid outlet opening, as well as a printing fluid source, a printer system, a printer system arrangement and a method of filling a printing fluid source.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The printing fluid container according to claim 1, further comprising a removable neck seal sealing the outer opening of the neck.

### Claim 3 (depends on 1)

The printing fluid container according to claim 1, wherein the closure device main body is removably connected to the neck.

### Claim 4 (depends on 1)

The printing fluid container according to claim 1, wherein:
the closure device main body comprises an outer opening at an outer surface of the closure device main body and a closure device printing fluid outlet passageway extending between the closure device printing fluid outlet opening and the outer opening of the closure device; and
the closure device printing fluid outlet opening is located within the closure device main body.

### Claim 5 (depends on 1)

The printing fluid container according to claim 1, wherein the sealing material layer comprises silicone.

### Claim 6 (depends on 1)

The printing fluid container according to claim 1, wherein the sealing material layer comprises a cut into its surface, wherein the cut is selected from a group consisting of line cut, cross-like cut, and star-like cut.
