Appeal 2007-0672
Application 10/399,702
the opening….having a pressure surface exposed
to inner pressure, said collar in a closed position
responding to the inner pressure by deforming in a
manner such that said collar becomes increasingly
support on the neck rim and sealingly closes the
opening.
As such, we construe independent claim 11 to be directed to a closure with a
collar that is able to function so that it can be releasably engaged with the
neck rim of the opening of a container. In addition, if there is pressure
within the container, a surface of the collar is capable of being exposed to
the pressure in the container. In response to pressure in the container, the
collar deforms in a manner such that the collar becomes increasingly
supported on the neck rim and sealingly closes the opening.
Independent Claims 24, 33 and 35 have similar language and thus are
similarly construed to be directed to a closure which includes a sealing
element having a deformable collar protruding radially inwardly. The collar
of the closure is capable of being releasably engaged with the neck rim of
the opening of a container. The collar has a surface that is capable of being
exposed to pressure inside a container. In response to pressure in the
container, the collar deforms in a manner such that the collar becomes
increasingly supported on the neck rim and is capable of sealingly closing a
container.
