Abstract
A thermoplastic container is provided with a venting structure to enhance the delivery therefrom of food products, including toppings and the like, in an en mass or molded form from the container. A deep drawn rupturable tip is formed in a concave bottom web of the container which can be ruptured by a fingernail or fork tine to vent the bottom of the contents to atmosphere and enhance dispensing of the entire contents by inverting the container. The tip is of lesser depth than the bottom concavity to permit stacking of containers one upon the other and normal positioning on a flat surface.
