Claims

1. A filling machine for filling product into a packaging container comprising;
at least one filling nozzle for ejection of liquid in a first general direction into the packaging container, wherein the filling nozzle is arranged in a dishbox having an opening through which the product is ejectable towards a package provided in a volume, the opening being selectively sealable by a sealing valve having a valve body with a portion dimensioned to be inserted in said opening, and a recess is arranged in an upper surface of the volume such that the valve body is at least partly insertable in the recess in the rest position.
2. The filling machine of claim 1, wherein an effective diameter of the opening is smaller than the effective diameter of the recess, referring to a diameter of engagement, such that a part of the valve body exposed towards the filling nozzles in a use position has not been exposed to atmosphere inside the volume when in a rest position.
3. The filling machine of claim 1, wherein the sealing valve is movable in the first general direction and perpendicular to said first general direction between a use position and a rest position.
4. The filling machine of claim 1, wherein the valve body is coupled to a turning shaft extending from an annular channel in an upper surface of the volume, and further comprising sealing means for sealing between the turning shaft and said channel when the valve body is positioned in the recess.
5. The filling machine of claim 4, wherein the turning shaft comprises individual projections abutting the inner wall channel, said projections being distributed around the circumference of the shaft.
6. The filling machine of claim 1, wherein the valve body comprises a resilient cover.
7. The filling machine of claim 4, wherein the sealing means are vulcanized to the turning shaft.
8. The filling machine of claim 5, wherein the projections are arranged at a lower end of the turning shaft and are configured to allow passage of dishing or sterilizing agents.
9. A valve arrangement for sealing an opening in a dishbox of a filling machine relative to a volume in which packages to be filled may be arranged, said system comprising:
a sealing valve having a valve body for sealing the opening; and
the valve body being at least partly insertable in a recess arranged in an upper surface of the volume.
10. The valve arrangement of claim 9, wherein the valve body is coupled to a turning shaft extending from an annular channel in an upper surface of the volume, further comprising sealing means for sealing between the turning shaft and the channel when the valve body is positioned in the recess, the sealing means having one state in which the opening is sealed by the valve body while the annular channel is open and another state in which the valve body is arranged in the recess and the sealing means provides a seal between the turning shaft and the channel.
