The present invention relates to an arrangement for portioning or dispensing viscous material from a pack, whereby the pack is positionable in an outer container and a portioning or dispensing unit includes a non-return valve which prevents the material from flowing back to the pack during portioning or dispensation. For being able to quickly place the pack in the outer container and quickly and safely lock a retaining portion as well as ensure than vital valve members of the non-return valve are not damaged during handling and operation of the portioning unit, the outer container is divided in a special way into two container members, whereby retaining members of the retaining device are integrated in the container members and whereby the valve seat of the non-return valve is surrounded by the retaining members of the retaining device.
