<p>The invention provides a constant head dispensing package for flavouring concentrate or other liquids. Dispensing at constant head is explained in the specification, and the invention resides in that the compensating chamber outlet is made of smaller area than the interior of the compensating chamber to prevent the compensating chamber from filling up with concentrate when the package is inverted and reinverted as it will be by virtue of the nature of the design and use of the package. It is preferred that the ports connecting the interior of the compensating chamber and the package body be as large as possible. </p> |
