Coupling device for dispensing of food

Coupling device for connection to a flexible container comprising a plastic foil for dispensing of food product in fluid form out of the same, comprising an outlet valve with a first end comprising at least one hole-creating part for penetration of the container and its plastic foil when connecting to the same, and a through-flow channel which merges into a second end for transfer of food product, where an outer portion of the hole-creating part is configured as an axially protruding spear point, which point is adapted to merge into at least one radially protruding edge configured to extend axially from the point in direction of the dispense for food product and connect to an inlet orifice at the through-flow channel, wherein food product can be discharged from the container via orifice openings after the container has been penetrated by the spear point which is provided with at least one outwards pointing tooth which works as at least one cutting element with at least two edges or corners or cutting edges configured to create a cutting effect on the container's plastic foil in at least two places in the plastic foil,

• wherein the through-flow channel is configured with a conical outer mantle surface which has an increasing size in a direction away from the inlet orifice, wherein the point and at least one protruding spear point edge comprises at least one such outwards pointing tooth configured as a step that mainly faces radially outwards with at least one outermost cutting edge being sharp and extending in a plane substantially perpendicular to the point's and/or spear point edge's axial extension.
