Abstract
A liquid dispenser is described which dispenses liquid through a sidewall of the dispenser. The dispenser includes an air pocket structure in a lower portion adjacent the container base and a dispensing exit at the same level as the air pocket structure. The dispenser can be squeezed to reduce the volume in the container and cause liquid to be ejected from the dispensing exit. The exit and air pocket structure are proportioned so that on release of pressure, air is sucked-back into the dispenser through the exit and air pocket to remove liquid in the exit and eliminate dripping. The air pocket is also designed to compensate for temperature increases of 30.degree. F. to 40.degree. F. without having product leakage. The dispenser can accommodate liquids of different viscosities and various preferred embodiments are disclosed for different dispenser applications.
