US Patent 10279975 Bottle with pressurizing feature under lateral load and associated method

A bottle is provided for storing an associated fluid product when filled. The bottle includes a first wall having an opening therein that is selectively opened and closed to allow the associated fluid product to be dispensed therethrough or stored in the bottle, respectively. A second wall is spaced from the first wall, and a third wall extending between the first and second walls. A compliant pleat extends along substantially an entirety of the first wall, second wall, and third wall and divides the bottle into first and second portions. The compliant pleat allows the first and second portions to move toward one another in response to a predetermined force and thereby increase pressure in the closed bottle.
