ABSTRACT:
A dispensing package including a plastic container having a surface recessed in portion of the container and an opening in the recessed portion of the container and a valve system in overlying position to the opening and including a valve member movable manually from a closed position to an open dispensing position is disclosed. The container has a flexible portion which can be squeezed for dispensing the product through the opening. In one form, the valve system comprises a fitment and a toggle valve pivoted on the fitment. The toggle valve includes a discharge passage which is closed and opened so that the product can be dispensed by squeezing the container. In another form, the toggle valve is pivoted directly in the recess on the plastic container. In another form, the valve system consists of a fitment having an opening and a valve member hinged to the fitment. In another form, the valve system comprises a valve member which engages a complementary surface on the opening of the container and is movable by a toggle action. The recess may extend partially across the upper surface of the container or completely across the upper surface of the container. In some forms, the plastic container has a modified upper surface to minimize accumulation of liquid product adjacent the outlet of the container.
