Abstract
A package and applicator for dispensing a product from a flexible closed tube having a weakened zone in one end is shown. A one-piece application unit is attached by a U-shaped portion whose legs are connected to the edges of the tube at the weakened zone end. The unit has a flexible spatula disposed facing the weakened zone and a cogged wheel for breaking the weakened zone. The wheel is attached on one side to said zone and on the other side to the inner face of the U-shaped base portion. Rotation of the cogged wheel opens the weakened zone and detaches it from the base portion, with the consequence that pressure on the flexible tube will deliver the product onto the spatula for application.
