Device for delayed dispensing of viscous liquids in which the plastic material of the dispensing container is selected for its ability to shrink in a predictable manner upon exposure to heat, age, light, or chemical activator; and the container shape and dimensions are selected to render the proper evacuation pressure according to the volume and viscosity of the charge to be dispensed. In various embodiments of the invention the shrink induced dispenser is used to dispense lubricants, inks, additives, and medications. In heat activated embodiments the inventiuon is capable of integral temperature responsive automatic flow control.
