ABSTRACT:
A disposable squeezable dispenser employing a flexible container filled with a mixture of air and the liquid to be dispensed. The dispenser employes only two main parts (other than the container itself) plus a ball and dip tube. One of the main parts is a hollow pull top which cooperates with the other main part in a sealing operation which prevents leakage when the dispenser is not in use.
