ABSTRACT:
Apparatus for dispensing predetermined amounts of viscous product. The apparatus has a conduit which is telescopically received with a cap. The cap and conduit define an expandable dosing chamber which expands to a predetermined maximum volume when product is introduced into the chamber through the conduit. A check valve prevents back flow of product through the conduit. Collapsing the chamber from its maximum volume to a minimum volume dispenses the product from the dosing chamber.
