<p>The present dual chamber sachet overcomes the problem of non-uniform dispensing when the sidewalls of the sachet are depressed. Through the use of a relatively thin intermediate divider wall, rounded corner edges at the lower end of each chamber of the sachet, tapered side edges up to the exit channel of each chamber of the sachet, and a relatively wide dispensing opening uniform dispensing can be achieved. This structure prevents the downward flow of substances in each chamber during dispensing. The substances are directed upwardly by the rounded lower corners of the sachet, the tapered upper walls and the wide dispensing opening. This relatively wide dispensing opening minimizes the back pressure caused by the substances flowing to a dispensing exit of a width less than that of the product chambers.</p> |
