<p>A container adapted to contain and dispense a product. Said container comprises a hollow body, a filling opening, a dispensing opening,, a valve and a flexible and resilient support means for said valve. Said flexible and resilient support means urges said valve against said dispensing opening, achieving a leak-tight engagement between said valve and said dispensing opening. Said flexible and resilient support means can be resiliency deformed by an external force acting on said valve whereby said leak -tight engagement between said valve and said dispensing opening is disengaged, allowing said contained product to be spread by said valve, Said flexible and resilient support means comprises a housing which fits the container and defines said dispensing opening at one extremity. Said housing comprising a resiliency deformable means urging said valve against said dispensing opening to achieve said leak-tight engagement. When the leak-tight engagement between said valve and said dispensing opening is disengaged a fluid flow pathway is created which has a cross-section of greater than 10% of the width of the dispensing opening.</p> |
