Summary
The invention relates to a valve sub assembly where a flexible valve member is retained by crimping in a closure member for the container. Such valve assemblies are used in containers such as ketchup bottles, sports drink bottles and the like. The application seeks to improve on the prior art by increasing the crimping force holding the vale member in place by increasing the crimping flange length from 1mm to 1.4mm. This increase it was claimed provided significantly increased retaining force. The Hearing Officer concluded that whilst extending the crimping flange might be an obvious way of increasing the holding force, increasing it to specifically 1.4mm as claimed was not clearly obvious. Applying the guidance inBlacklight Power Inc. v The Comptroller-General of Patents,the applicant was given the benefit of the doubt and the application was allowed to proceed.
